Description

LIGHT-STEEL STRUCTURE

RESIDENTIAL FRAMING SYSTEM TECHNICAL FIELD

[0001] The present invention relates to the field of steel structure for construction, especially to a light-steel structure residential framing system.

BACKGROUND OF THE INVENTION

[0002] There are two dominant types of structure currently used in civil buildings, including the steel reinforced concrete frame structure and the steel structure.

[0003] Building using conventional steel reinforced concrete frame structure building is the most mainstream building type in China, which has complicated construction procedures and low construction efficiency. In particular, mould plates are required to be assembled/disassembled during construction, which not only reduces construction efficiency but also increases construction cost. In addition, it has large dead weight and consumes large amount of materials, resulting in great material and energy consumptions. 1 [0004] Currently, common steel frame structure is widely used in industrial buildings. In the mounting procedure of said steel frame structure, international standard hot-rolled steel profiles are used, which are fastened to one another via welding or bolt or the like to form a frame structure, in which steel reinforced concrete floors and wall envelope structures are laid. Compared to the steel reinforced concrete frame structure building, the steel frame structure building is more convenient and less time-consuming in construction. However, the steel frame building has several disadvantages, including costly materials and complicated manufacture, as well as the involvements of manufacture using large factories and hoist using on-site heavy lifting equipment. In addition, the walls are usually assembled with prefabricated walls which are prone to crack due to the difference in expansion rate than the steel frame, resulting in occurrence of water seepage or even personal safety problems including wall collapse or wall fall.

[0005] Light-steel structure building adopts cold-formed thin-walled steel to form an integral multi-ribbed bearing structure, in which advantages may be achieved like easy manufacture of steel, overall light structure and good seismic performance, etc.. However, for a light-steel structure building, several disadvantages are also present, including poor resistances to wind and torsion, susceptibility to rusting and poor durability of the steel, etc.. If light-steel structure is combined with lightweight waterproof concrete technology, steel is wrapped by the lightweight waterproof concrete. Consequently, resistances to torsion and 2 shear can be significantly improved, and corrosion of the steel can be reduced due to isolation from air and water. As a result, the building may have excellent dampproof, waterproof and energy saving performances. However, the solid web C-shaped steels used in a conventional light-steel structure building need to be manufactured and cut in the factory or on-site according to the actual needs, and thus may have many different sizes. Furthermore, the distances between each of the members have to be measured for a proper location and assembling. These procedures are done in such a crude way that the manufacturing and assembling efficiencies are low and also the assembling is carried out arbitrarily to a large extent, which goes against standardized construction and quality control. Furthermore, the solid web C-shaped steel is adverse to through-flow of the lightweight waterproof concrete, such that the lightweight waterproof concrete cannot be solidified as to form an entirety.

SUMMARY OF THE INVENTION

[0006] The technical problem that the present invention aims to solve is to provide a novel light-steel structure residential framing system with high assembling efficiency and low construction cost.

[0007] A further object of the present invention is to provide a light-steel structure residential framing system that facilitates cast and through-flow 3 of the lightweight concrete.

[0008] The present invention provides a light-steel structure residential framing system, comprising steel grade beams, steel beam columns vertically arranged on the steel grade beams, girth beams transversally arranged and fixedly connected with the steel beam columns, steel floor beams placed on the girth beams and fixedly connected with the steel beam columns, roof beams provided on the roof and fixedly connected with the steel beam columns. The steel grade beams, the steel beam columns, the girth beams and the steel floor beams each has a plurality of connecting portions, each kind of the plurality of connecting portions are molded in a single stamping process with a predetermined interval (module).

[0009] Preferably, the steel grade beam comprises a web and two flanges, and positioning bases configured for catching the steel beam columns are disposed on an inner wall of the web. The positioning base consists of two parallelly arranged blocks between which a gap is formed for catching the steel beam column. The steel beam column is C-shaped in cross section and comprises a web and two flanges, the middle region of the web of the steel beam column is provided with rectangular openings for receiving the girth beams, and the two inner edges of each of the rectangular openings in the direction of the length direction of the web are respectively provided with catching blocks. The girth beam is a square tubing, the middle regions of the top and bottom surfaces of the 4 girth beam are symmetrically provided with first slots respectively, the first slots are oblong slots opened in the width direction of the top and bottom surface, and the catching blocks are engaged with the first slots. The steel floor beam comprises a web and two flanges, and the steel floor beam is disposed sideways on the girth beam enabling the web of the steel floor beam to be perpendicular to the top and bottom surfaces of the girth beam, the steel floor beam and fixedly connected with the web of the steel beam column through the web thereof. In this case, the plurality of connecting portions, including the positioning bases of the steel grade beam, the rectangular openings of the web of the C-shaped steel beam and the first slots of the girth beam, are each molded in a single stamping process with a predetermined interval (module). Preferably, the webs and/or the flanges of the steel grade beam, the steel beam column, the girth beam and the steel floor beam are each provided with a plurality of division reference lines for indicating the intervals (module).

[0010] Light-steel members used in the present invention are manufactured under standard and modular procedures and can be rapidly and easily assembled together to form an integral steel structure frame. The web of the steel grade beam is provided with positioning bases, by means of which the steel beam column can be positioned rapidly and fastened on the steel grade beam. The web of the steel beam column is provided with rectangular openings into which the girth beam can be easily inserted, so that the girth beam can be connected with the steel beam column to form an entirety. The steel floor beam can be easily 5 placed on the girth beam and fixedly connected with the steel beam column. The roof beam can be easily placed on the topmost girth beam and fixedly connected with the steel beam column. In this way, all the member can be easily assembled to form an entirety. The plurality of connecting portions, such as the positioning bases of the steel grade beams, the rectangular openings of the C-shaped steel beam column, and the first slots of the girth beams, etc., are each molded in a single stamping process with a predetermined interval (module), so that the members can be rapidly positioned and connected to one another during assembling of the whole steel frame. Compared with construction of the current steel structure building, the distance-measuring and positioning procedure is significantly simplified, construction efficiency is increased, and time consumption is greatly reduced.

Thus reliability of the cast concrete is ensured while corrosion resistance of each member is significantly improved. Besides, the plumbing and electricity wires can be easily assembled since said openings allow for passages of the plumbing and electricity wires, without the need to provide any additional layer for wires and pipes. These openings can enhance the path for heat and sound transfers, so that heat insulation and sound insulation properties can be improved for the walls and floors. With the third openings arranged on the web of the steel floor beam, when the steel floor beam is subject to a vertical force from the floor, said vertical force can be dispersed along both sides of the third openings so that vibration is effectively reduced. Furthermore, the third openings can also reduce the dead weight of the members so as to relieve pressure on the C-shaped steel beam column. Also in this way, use of materials is lessened and construction cost is lowered. 7

DETAILED DESCRIPTION OF THE INVENTION

[0026] The embodiments of the present invention are described in detail below in conjunction with the drawings.

[0027] Fig. 1 is a three-dimensional illustration of one embodiment of a light-steel structure residential framing system according to the present invention. The embodiment of the present invention is used for rapid assembling of a light-steel structure residential framing system. A light-steel framing house is built by assembling plates inside and outside 9 each light-steel member of the assembled framing system and casting lightweight waterproof concrete into the closed space defined by the plates and the light-steel members.

[0028] One embodiment of the present invention provides a light-steel structure residential framing system, comprising a plurality of grade beams 11, a plurality of steel beam columns 12 vertically arranged onto the steel grade beams 11, a plurality of girth beam 13 transversally arranged and fixedly connected with the steel beam columns 12, a plurality of steel floor beams 14 placed over the girth beams 13 and fixedly connected with the steel beam columns 12, a plurality of roof beams 15 provided on the roof and fixedly connected with the steel beam columns.

Each of the positioning bases 113 consists of two parallelly arranged blocks 1131, between which a gap is molded for catching the steel beam column. The steel beam column 12 is C-shaped in cross section and comprises a web 121 and two flanges 122. The middle part of the web 121 of the C-shaped steel beam column is 10 provided with a plurality of rectangular openings 123 for receiving the girth beams 13, and the two inner edges of each of the rectangular openings 123 in the length direction of the web are respectively provided with a catching block 124. The girth beam 13 is a square tubing, the middle portions of the top and bottom surfaces of the girth beam 13 are respectively symmetrically provided with a first slot 131 arranged in the width direction of the top and bottom surfaces, and the catching blocks 124 are engaged with the first slots 131. The steel floor beam 14 comprises a web 141 and two flanges 142. The steel floor beam 14 is laterally disposed over the girth beam 13 and fixedly connected with the web 121 of the C-shaped steel beam column 12 through the web 131 thereof. According to the load and span, the steel floor beam 14 or the steel beam column 12 can be used as the roof beam 15, without the need of a special one. The roof beams 15 are disposed sideways onto the topmost girth beam 13 and fixedly connected with the external surface of the web of the steel beam column 12. In case of a gable roof building, the roof beams 15 are disposed sideways onto the top girth beams 13 obliquely, and the roof beams which extend obliquely on both sides of the building contact and are fixed with each other at the ridge of the roof. In case of a flat roof building, the roof beams 15 is placed sideways onto the topmost girth beams 13 transversally.

[0030] In the above embodiment, the positioning bases 113, the rectangular openings 123 of the C-shaped steel beam column and the first slots 131 are included in the plurality of connecting portions, each being 11 molded in a single stamping process with a predetermined interval (module). Preferably, the webs and/or the flanges of the steel grade beam 11, the steel beam column 12, the girth beam 13 and the steel floor beam 14 are each provided with a plurality of division reference lines for indicating the intervals (module).

[0031] The light-steel members used in the present invention are manufactured under standard and modulus procedures and can be rapidly and easily assembled together to form an integral steel structure frame. The web of the steel grade beam 11 is provided with positioning bases 113, and the steel beam column 12 can be rapidly positioned and clamped on the grade beam 11. The web of the steel beam column 12 is provided with rectangular openings 123, into which the girth beam 13 can be easily inserted so that the girth beam 13 can be connected with the steel beam column 12 to form an entirety. The steel floor beam 14 can be easily placed on the girth beam 13 and fixedly connected with the steel beam column 12. The roof beam 15 can be easily placed on the topmost girth beam 13 and fixedly connected with the steel beam column 12. In this way, each light-steel member can be easily assembled together to form an entirety. The connecting portions, such as the positioning bases 113 of the steel grade beams 11, the rectangular openings 123 of the C-shaped steel beam column 12, and the first slots 131 of the girth beams 13, etc., are each molded in a single stamping process with a predetermined interval (module), so that the light-steel members can be rapidly positioned and connected with one another during assembling of the whole steel frame. 12

As a result, the distance-measuring and positioning procedure during assembling of the steel beam column can be significantly simplified than construction of current steel structure building, and construction efficiency is considerably increased also with a great reduction in time consumption. Assembling with the standardized and modular light-steel members also greatly saves construction materials and significantly reduces construction cost. In addition, in order to facilitate division of each steel member into standard lengths by the workers according to actual need, the webs and/or the flanges of the above steel grad beam 11, the steel beam column 12, the girth beam 13 and the steel floor beam 14 are further provided with division reference lines configured for indicating the intervals (module), so that assembling efficiency is further improved.

[0032] At the same time, in addition to being used for assembling and fixation of the girth beam 13, the rectangular openings 123 of the steel beam column 12 can be further used as a casting mouth for the lightweight waterproof concrete, which facilitates through-flow of the lightweight waterproof concrete and thus solidification thereof to form an entirety.

[0033] Fig. 2 is a structural illustration of the steel grade beam llof Fig. 1. As shown in Fig. 2, the steel grade beam of the light-steel structure residential framing system comprises a web 111 and two flanges 112. Preferably, the steel grade beam has a U-shaped cross section. The inner 13 wall of the web 111 is provided with positioning bases 113 for connection with the steel beam column 12. The positioning bases 113 are preferably symmetrically arranged on the inner wall of the web 111. Each of the positioning bases 113 consist of two parallelly arranged blocks 1131, between which a gap is formed for catching the steel beam column. As shown in Fig. 3, in one embodiment, the gap corresponds to the thickness of the web of the steel beam column 12. The U-shaped steel grade beam member 11 is connected with the vertically disposed steel beam column 12 by means of the positioning base 113, so that rapid positioning and temporary fixing of the steel beam column 12 can be achieved, which significantly simplifies the distance-measuring and positioning procedure during assembling of the steel beam column 12.

[0034] More preferably, both flanges 112 of the steel grade beam 11 are provided with a plurality of first mounting holes 115 which are symmetric with each other and through which a plurality of bolts are able to pass. The first mounting holes are configured to establish a bolt connection with positioned steel beam column 12. Correspondingly, the flanges 122 of the steel beam column 12 are provided with a plurality of third mounting holes 127 that will be described below. In the embodiment, the positioned steel beam column 12 can be further fastened by means of the first mounting hole 115 on the flanges 112 in such a way that the assembling can be carried out in an easy and reliable way.

[0035] More preferably, a plurality of first openings 117 are provided in 14 the middle part of the web 111. In the embodiment, the first openings 117 allow for passage of the plumbing and electricity wires, which facilitates flow of the concrete during construction of the cast-in-place walls and floors. Besides, due to the existence of the first openings 117, dead weight of the members and thus consumption of materials can be reduced.

[0036] More preferably, the web 111 of the steel grade beam 11 is further provided with symmetrical slotted holes 116 reserved for connection with the foundation, so that pre-embedded members can pass through and fix the steel grade beam.

[0037] The positioning bases 113, the first mounting holes 115, the slotted holes 116 and the first openings 117 are included in the plurality of connecting portions, each being molded in single stamping processes with a predetermined interval (module m). The manufacture is simple and convenient, and thus is adapted for industrial production. Preferably, the flanges 112 are respectively provided with division reference lines 118 for indicating the intervals (module), so as to facilitate division of U-shaped steel grade beam member into standard lengths by the workers according to the actual need and thus achieve modulus assembling, thereby improving assembling efficiency. Apparently, the web 111 may also be provided with division reference lines for indicating the intervals (module).

[0038] As shown in Fig. 4, the steel beam column 12 is C-shaped in cross 15 section, and comprises a web 121 and two flanges 122. Preferably, the outer edge of the flange 122 is bent inward, so that bending resistance of the steel beam column is greatly improved. The web 121 of the C-shaped steel beam column 12 is provided with rectangular openings 123 in the middle region, the two inner edges of each of the rectangular openings 123 in the direction of the length direction of the web 121 are respectively provided with a catching block 124. The catching block 124 and the web 121 are integrally formed or fixedly connected with each other. For example, the catching block may be a protrusion provided at the inner edge of the rectangular openings 123. In particular, the two catching blocks 124 are symmetrically disposed at the central line of the web 121, so as to ensure that the C-shaped steel beam column 12 is under an even stress, thereby improving stability of mounting and thus preventing occurrence of any safety risk. The rectangular openings 123 are used to mount the girth beam 13, which is able to pass through the rectangular openings 123. Besides, the girth beam 13 is provided with first slots 131, into which the catching blocks 124 are inserted so that engagement between the girth beam 13 and the steel beam column 12 is achieved. This will be further described in detail in the following.

[0039] Furthermore, the web 121 of the C-shaped steel beam column 12 is provided with a plurality of second mounting holes 124 through which bolts can pass, and the second hole is configured to establish a bolt connection with the steel floor beam 14. Correspondingly, the web of the steel floor beam 14 is provided with a plurality of fourth mounting holes 16 144 aligning with the second mounting holes 124, which will be described in detail in the following.

[0040] Furthermore, two opposite margins of the web 121 of the C-shaped steel beam column 12 are respectively provided with a plurality of second slots 126 for mounting the wallboard hanging members 16, the second slots at the two opposite margins are symmetrically arranged in a width direction of the steel beam column. The second slots are oblong in shape, being arranged in the length direction of the web 121. Preferably, the second slots 126 are located near to the edges at the two opposite margins of the web between two adjacent rectangular openings 124. In the embodiment, the inner wallboard and the external wallboard can be rapidly positioned and fixed on the C-shaped steel beam column 12 by means of the hanging members, and thus mounting efficiency can be greatly improved. During construction of the cast-in-place walls, the slotted holes can provide larger pulling force for the hanging member and the inner and external wallboards than the bolts, so that the mould plates can be substituted with the wallboards, avoiding disassembling of the mould plates and thus saving large amount of labor force and materials.

[0041] Furthermore, the flange 122 of the C-shaped steel beam column 12 is provided with a plurality of third mounting holes 127 for bolt connections with the steel grade beams. As discussed above, the third mounting holes 127 are configured to establish bolt connections with the first mounting holes 115 of the steel grade beam 11. After the C-shaped 17 steel beam column 12 is vertically connected with the positioning bases 113 of the steel grade beam 11, the third mounting holes 127 on the C-shaped steel beam column 12 aligning with the first mounting holes on the steel grade beam 11, so that bolt connection is established.

[0042] In the embodiment, by means of the third mounting holes 127 on the flange 122 of the C-shaped steel beam column as well as the second mounting holes 125 on the web 121, the steel grade beam, steel floor beam and the hanging member that have already been positioned can be further fastened, so as to ensure stability of the whole residential steel framing system.

[0043] More preferably, the rectangular openings 123, the second mounting holes 125, the second slots 126, and the third mounting holes 127 are included in the plurality of connecting portions, each being molded in a single stamping process with a predetermined interval (module m). The manufacture is simple and convenient, and thus is adapted for industrial production. Moreover, normalization of dimensions of the floor height, the doors and windows and the wall board is achieved. Excellent flexibility is present in adjustment of the steel beam column member 12 according to multiples of the modulus. More preferably, the web 121 and the flange 122 are respectively provided with a division reference line 118 for indicating the intervals (module), so as to facilitate division of the steel beam column into standard lengths by the workers according to actual needs, thereby further improving the mounting 18 efficiency.

[0044] More preferably, as shown in Fig. 4, a surface of the web 121 of the steel beam column 12 is pressed to form an inwardly recessed stiffener section 128, so as to effectively improve structural strength of the steel beam column 12. It is to be noted that the stiffener section 128 is recessed inwardly when viewed from the outer surface to the inner surface of the web 121. However, the stiffener section 128 would be protruding inwardly when viewed from the interior cavity defined by the web 121 and the two flanges 122. Furthermore, the stiffener section 128 of the steel beam column 12 is continuously stamped to form a continuous stiffening region between the two adjacent rectangular openings 123 in the length direction of the web, between the second slots 126 that are symmetrical in the width direction, and between the two side edges in the width direction of the web 121 and the rectangular openings 123, thereby improving the stiffness of the steel beam column 12 in a more effective way. By doing so, the stiffener section 128 includes a transversal stiffener 1281 and a longitudinal stiffener 1282, so as to enhance transversal and longitudinal strengths of the steel beam column and thus effectively improve shock resistance of the steel beam column. The enhanced embossment of the steel beam column 12 is preferably rolling molded at one time, and thus the production efficiency is high and the steel beam column is adapted for mass production.

[0045] As shown in Fig. 5, the girth beam 13 is a square light-steel tubing 19 with a square in section which consists of top and bottom surfaces and left and right sidewalls. The middle parts of the top and bottom surfaces are respectively provided with first slots 131. The first slots are oblong slots arranged in the width direction of the top and bottom surfaces. As discussed above, the first slots 131 are engaged with the catching blocks 124 on the web of the steel beam column 12 to form an engagement. As shown in Fig. 6, the girth beam 13 is capable of passing through the C-shaped steel beam column 12 by means of the rectangular openings 123 on the web 121 of the C-shaped steel beam column during fabrication, and the corresponding first slots 131 on the girth beam are thus capable of engaging with the catching blocks 124 to achieve rapid positioning and fixing of the girth beam 13. As a result, it significantly simplifies the distance-measuring and positioning procedure during assembling of the C-shaped steel beam column 12, and the height of the girth beam 13 or even the steel floor beam 14 can be rapidly determined. It is thus unnecessary for the C-shaped steel beam column 12 to be disconnected for a building with more than two levels, thus avoiding the risk of inadequacy in mechanics property of the transition connecting portions after the disconnection.

[0046] More preferably, the middle region of the top surface of the girth beam 13 and the middle region of the bottom surface of the girth beam 13 both are further provided with a plurality of second openings 132. The second openings 132 facilitate flow of the concrete into the interior of the members, so that corrosion resistance of the members is greatly improved. 20

More preferably, third slots 133 are provided at both side edges of the second openings 132 on the top and bottom surfaces of the girth beam 13. The third slots are oblong in shape, being arranged in the length direction of the top and bottom surfaces. The third slots 133 are configured to engage with specific comers to improve the generality of the girth beam 13 ,so that the girth beam can function as a floor beam, a partial stiffening beam for a door or window, a trimmer beam for a door or window, and a simple wall post. For example, when the girth beam 13 is mounted on the transversal steel beam member vertically as a simple wall post, it can be rapidly positioned and temporarily fixed by means of the third slot 133 and the specific comers. If further fastening of the girth beam 13 is desired, it is all necessary to mount corresponding bolts on the transversal steel beam members with the girth beam unbolted. In this way, the assembling efficiency can be greatly improvement. Obviously, other method, such as welding or rivet joint, can also be used to fasten the transversal steel beam members.

[0047] More preferably, the first slots 131, the second openings 132 and the third slots 133 on the girth beam 13 included in the plurality of connecting portions are each molded in single stamping processes with predetermined intervals (module), thereby facilitating assembling and connection with the steel beam column 12 and other corresponding members.

[0048] As shown in Fig. 7, the steel floor beam 14 includes a web 141 21 and two flanges 142. The steel floor beam 14 is disposed sideways on the girth beam 13, and fixedly connected with the web 142 of the steel beam column 12 through the web 141 of the steel floor beam 14.

[0049] Fig. 8 further shows the structural illustration of the steel floor beam 14. The web wall 141 of the steel floor beam 14 is provided with several sets of fourth mounting holes 144 arranged in the middle region of the web 141 and both side regions of the web 141 respectively. As discussed above, the fourth mounting holes 144 establish bolt connection with the second mounting holes 125 on the web of the steel beam column 12. In the embodiment, after the C-shaped steel beam column 12 is fixedly connected with the girth beam 13, the steel floor beam 14 is assembled between two girth beams 13. Namely, the steel floor beam 14 is disposed sideways onto the fixed girth beams 13, so that the web 141 of the steel floor beam 14 abuts against the web 121 of the C-shaped steel beam column 12 and is thus positioned. Then the steel floor beam 14 is moved in a longitudinal direction to let the fourth mounting holes 144 align with the second mounting holes 125, and then bolts are used to connect the fourth mounting holes 144 and the corresponding second mounting holes 125. In this way, the use of bolt connection avoids any potential safety risk that may be caused by mounting of an on-site power supply when welding method is adopted, and also accelerates the assembling procedure.

[0050] In addition, as shown in Fig. 8, a plurality of third openings 143 22 are provided in the middle region of the web of the steel floor beam 14. The fourth mounting holes 144 are located in a region between two adjacent third openings 143. The third openings 143 are designed to be square in shape, although they may have other shapes like triangle, rhombus, or trapezoid. When the steel floor beam is subjected to a vertical force from the floor slab, the third opening 143 disperses the vertical force along both sides of the third opening 143 to effectively reduce the vibration. Furthermore, due to the existence of the third openings, the dead weight of the members can be reduced and thus the pressure on the C-shaped steel beam column 12 can be relieved, and also the materials consumption and cost can be reduced. As shown in Fig. 8, two opposite margins of the web of the steel floor are symmetrically provided with a plurality of engaging holes 145, each pair of the engaging holes are located at two sides of a region between two adjacent third openings 143 on the web 141 of the steel floor beam 14. The engaging holes are configured to rapidly engage with the keel to improve the application flexibility of the steel floor beam 14.

[0051] It is to be noted that the rectangular openings 123 of the C-shaped steel beam column 12, the third openings 143 of the steel floor beam 14 and the second openings 132 of the girth beam 13 allow passage of the plumbing and electricity wires without the need to provide any additional layer for wires and pipes, which is favorable for assembling of wires and pipes. This also facilitates flow of the concrete so that it is filled in the interior of each member, and thus reliability of concrete casting is 23 guaranteed while corrosion resistance of each member is significantly improved. Furthermore, the rectangular openings 123, the third openings 143 and the second openings 132 can enhance the path for heat and sound transfers, so that heat insulation and sound insulation properties can be improved for the walls and floors.

It 24 is to be noted that the stiffener section 146 is recessed inwardly when viewed from the outer surface to the inner surface of the web 141. However, the stiffener section 146 would be protruding inwardly when viewed from the interior cavity defined by the web 141 and the two flanges 142. Preferably, the stiffener section 146 includes a transversal stiffener 1461 and a longitudinal stiffener 1462 and forms a continuous stiffening region which is pound sign “#” shaped. The third openings 143 in the middle region of the web 141 are preferably located within the stiffener section 146, while the fourth mounting holes 144 and the engaging holes 145 are located outside the stiffener section 146. The third openings 143 located within the stiffener section 146 further help to disperse the vertical force along both sides of the third openings 143, and thus vibration resulted from the vertical force could be effectively reduced. The stiffener section 146 consisting of the transversal stiffener and the longitudinal stiffener can enhance the transversal strength and the longitudinal strength, i.e. stiffness, so as to effectively improve bearing capability and shock resistance of the steel floor beam and further reduce the vibration resulted from the vertical force. Preferably, the enhanced embossment of the steel beam column 14 is preferably rolling molded at one time, and thus the production efficiency is high and the steel beam column is adapted for mass production.

All the members can be manufactured simply and rapidly, and normalization and standardization of the whole light-steel structure residential framing system can be realized. The members can be rapidly assembled together to form an integral framing, which significantly improves construction efficiency of the light-steel structure frame system. Moreover, the webs or the flanges of the steel grade beam 11, the steel beam column 12, the girth beam 13 and the steel floor beam 14 are respectively provided with division reference lines for indicating the intervals (module), so as to facilitate the positioning and distance-measuring procedure for the workers during assembling, thereby increasing construction efficiency.

[0055] In one embodiment, according to the load and span, the steel floor beam or the steel beam column can be used as the roof beam, without the need of designing a specific one, so that lower construction cost is achieved. As shown in Fig. 9 and Fig. 10, in this embodiment, the roof 26 beam 15 has the structure of the steel floor beam. Obviously, in other embodiments, the structure of the steel post can be used. In the embodiment of Fig. 9, the building structure is pinnacle-topped. The roof beams 15 are disposed sideways on the topmost girth beam 13. That is, a flange 151 of the roof beam 15 is placed on the girth beam 13. Meanwhile, the external surface of the web 151 of the roof beam 15 abuts against the web 121 of the steel beam column 12, and they are bolt fastened by means of the mounting holes of the web of the roof beam 15 and the mounting holes of the web of the steel beam column 12. The roof beams 15 obliquely disposed at both sides of the building contact each other and are fixed together at the ridge of the roof. Preferably, the two steel floor beams are fixed to each other to form an entirety in such a way that their webs abut against each other, so that they can be used as a purlin 153 which is connected below the ridge. The roof beam can be assembled in a simple and convenient way, and the use of the steel floor beam or the steel beam column provides excellent strength and stability.

[0056] Preferably, as shown in Fig. 11, a wallboard hanging member 16 configured for mounting inner and outer plates is arranged on both sides of the C-shaped steel beam column in the width direction. In particular, the inner and outer wallboards of the building are connected with the steel beam column 12 by means of the wallboard hanging member 16. As shown in Fig. 12, the wallboard hanging member 16 includes a bearing plate 161 configured for attaching the wallboard and a mounting plate 162 for engaging with the steel beam column 12. The bearing plate 161 is 27 provided with upper baffles 1611 and a lower baffle 1612 at one side of the facing the wallboard. A notch 1613 is arranged at the other side of the bearing plate 161 near to the steel beam column 12, and the mounting plate 162 is vertically attached to an edge of the notch 1613 of the bearing plate 161. One side of the mounting plate 162 facing the steel beam column 12 is provided with a hanger 1623. In the embodiment, as shown in Fig. 10, the wallboard hanging member is engaged with the corresponding second slot 126 of the steel beam column 12 by means of the hanger 1623, so that temporary fixation and convenient assembling can be achieved.

[0057] In order to further fasten the hanger on the steel beam column 12, the mounting plate 162 is preferably further provided with a plurality of fifth mounting holes 1622 for bolt connection. When the wallboard hanging member is engaged with the second slots 126 of the steel beam column 12 by means of the hanger 1623, the fifth mounting holes 1622 on wallboard hanging member 16 align with the second mounting holes 125 on the side edge of the web of the steel beam column 12, and thus a further fastening is achieved by means of bolt connection.

[0058] In order to improve the cooperating performance between the hanger 1623 and the second slots 126, multiple hangers 1623 are used for the connection so as to reduce clearance error between the hanger 1623 and the second slots 126 and thus prevent the hanging member from swinging outwardly and becoming loosened. Preferably, two hangers 28 1623 are arranged in the vertical direction. Meanwhile, considering the manufacturing process of the members, it would be more cost effective to arrange the hanger 1623 at the edge of the mounting plate 162 and have the hanger to be integrally formed with the hanging member. Therefore, manufacture cost is low while the final product still has excellent stmcture strength.

[0059] More preferably, one area of the bearing plate 161 close to the notch 1613 is constructed as a triangular panel. Since the hanging member is mainly subject to pressure from the wall, the hanging member may have better shock resistance and bearing capacity because of this triangular panel.

[0061] More preferably, the upper baffles 1611 and the lower baffle 1612 are located at one side of the bearing plate 161 facing the wallboard with the upper baffles 1161 at the two opposite sides and the lower baffle 1612 in the middle. Obviously, the positioning of the upper baffles and the lower baffle can be adjusted according to actual need. For example, the upper baffle is located in the middle while the lower baffles are located at the two opposite sides, or the upper baffle is located at left side while the lower baffle is located at the right side. 29 [0062] By means of fixing the inner and outer wallboards by the hanging member 16 via a combined method of engagement and bolt connection, the hanging member 16 can be rapidly positioned and fixed on the steel beam column 12, thus greatly improving assembling efficiency. During the construction of cast-in-place walls, engagement can provide better mechanical property for the hanging member and the inner and outer wallboards compared to bolt connection and welding. In addition, the implementation is less costly.

[0063] The present invention provides standardized and modularized light-steel members, including the steel grade beam, the steel beam column, the girth beam, the steel floor beam, the roof beam and the wallboard hanging member. The light-steel members can be rapidly and easily assembled together to form an integral framing system. This greatly improves assembling efficiency. The use of the standardized and modularized light-steel members in the construction also significantly saves construction materials, and thus greatly lowers the cost. In addition, embodiments of the present invention are provided with the rectangular openings 123 of the steel beam column, the third openings 143 of the steel floor beam 14, the second openings 132 of the girth beam 13, etc.. These features can not only be used for assembling of the members, such as the assembling of the girth beam and the steel beam column, but also allow passage of plumbing and electricity wires so as to facilitate assembling of the plumbing and electricity wires. More advantageously, this may facilitate flow and circulation of the lightweight waterproof 30 concrete during construction of the cast-in-place wallboards and floors, so that the concrete can be filled in the interior of each member and a reliable, uniform, steady and sturdy integral building entirety is resulted after solidification of the concrete.

[0064] When a light-steel residence is being constructed, the light-steel members are respectively assembled to form a light-steel structure framing system initially, then the inner and outer plates are mounted on the inner and outer sides of the light-steel members, and then lightweight waterproof compound concrete is cast on site into the inner cavity defined by the inner and outer plates. The whole building walls and floors are cast integrally to form a steady and sturdy building entirety. During the cast on site, the inner and outer plates act as the mold plates, and after the cast on site is completed, the inner and outer plates can be used as superficial layer directly without having to be removed. In the implementation of the embodiments of the present invention, assembling efficiency is improved and materials consumption as well as construction cost are lowered. The present invention thus provides a novel energy and material saving light-steel structure residential framing system, which is worth to be popularized.
