Example 1

Referring to fig. 1 and 2, the present utility model provides a steel structure support beam for construction, comprising a support beam body 1, the support beam body 1 comprising a top plate 11, a bottom plate 12 and a vertical plate 13 having a rectangular shape. The lengths of the top plate, the bottom plate and the vertical plate are equal, and the width of the top plate is smaller than that of the bottom plate. The top plate and the bottom plate are relatively parallel, and the vertical plate is arranged between the top plate and the vertical plate. Specifically, one side wall of the vertical plate in the length direction is vertically connected with one side wall of the top plate in the length direction, and the other side wall of the vertical plate in the length direction is vertically connected with the middle position of the bottom plate in the length direction.

In addition, the T-shaped supporting beam body can be made of steel metal materials, glass fiber and other high-strength composite materials, and can achieve the same functions and effects, and the T-shaped supporting beam body can be processed by electroplating or plastic spraying on the steel metal materials, so that the service life of the T-shaped supporting beam body is longer.

Two purlines are needed to be made in the traditional steel structure roof heat preservation method, and the cost is high, and the support beam body provided by the utility model only needs one purline, so that the cost is saved and the space is also saved; in addition, the scaffold is not required to be built under the purlines, and the profiled steel sheet is fixed from bottom to top, which is tedious and labor-consuming. Therefore, the utility model can reduce the manufacturing cost of the steel structure roof enclosure and heat preservation system, can save the space by reducing the height of the roof, has the comprehensive cost lower than that of two conventional methods, can achieve the same use effect while saving the national resources, and has good social and economic benefits.

Example two

Referring to fig. 3 and 4, the utility model provides a steel structure supporting system for building, which comprises a bearing girder 2, a roofing tile 3, a profiled steel sheet 4, a heat insulation and sound insulation board 5, a heat insulation pad 6, a self-adhesive waterproof coiled material 7 and a supporting beam body 1 in the technical scheme. Specifically, the bearing girder is arranged on the top of the roof in parallel to the water slope direction and is used as the bearing girder of the roof. The two or more support beam bodies are arranged on the bearing girder at intervals along the downhill direction of the bearing girder and are vertical to the bearing girder. Preferably, the bottom plate of the support beam body is fixed with the bearing main beam by welding or bolting.

In this embodiment, an accommodating space for accommodating the heat insulating and sound insulating plate can be formed together between two adjacent support beam bodies. The length of the profiled steel sheet and the length of the sound insulation and heat preservation plate are smaller than the distance between the vertical plates of the two adjacent support beam bodies and larger than the distance between the two adjacent bottom plates, before the heat insulation and sound preservation plate is installed and contained, the profiled steel sheet is placed into the containing space, and two ends of the profiled steel sheet are respectively connected with the two adjacent vertical plates or the two adjacent bottom plates. Preferably, the profiled steel sheet is a corrugated profiled steel sheet, and the length direction of the profiled steel sheet is the same as the direction of the roof along the water slope.

Preferably, the connection mode between the profiled steel sheet and the bottom plate can be welding, weather-proof adhesive bonding, self-tapping screw locking or direct placement.

In this embodiment, the length of heat preservation acoustic celotex board and profiled steel sheet's length looks adaptation, and the thickness of heat preservation acoustic celotex board is less than the height of riser. The heat-insulating sound-insulating plate is embedded into the accommodating space and is connected with the upper surface of the profiled steel sheet. The heat-insulating sound-insulating plate with little hardness and high flatness can be adopted, such as an extruded sheet and the like, so that the whole splicing surface is smoother after the upper surface of the profiled steel sheet is paved, and the self-adhesive waterproof coiled material adhered to the upper surface of the heat-insulating sound-insulating plate is smoother. The water-draining coiled material is self-adhesive waterproof coiled material, the self-adhesive waterproof coiled material is adhered to the other end of the whole slope surface along the length direction of the supporting beam body in a seamless way, and the self-adhesive waterproof coiled material is adhered to the surface of the heat-insulating sound-insulating plate along the outer surface of the heat-insulating pad. The junction of two self-adhesive waterproof coiled materials is positioned above the heat insulation pad and can be stuck in a staggered way, and a seamless integral waterproof surface can be formed above the heat insulation and sound insulation plate between two adjacent support beam bodies. The self-adhesive waterproof coiled material has the advantages that in case of water leakage of roof tiles, water can flow down from the eave edges on the left side and the right side of the roof above the self-adhesive waterproof coiled material and cannot flow into a room; if the water leakage is not great, the water stays above the coiled material for a certain time and naturally evaporates. Through the double arrangement, the roof waterproof can meet the first-level waterproof requirement in national standards.

In this embodiment, the roof tile is installed above the top plate of the support beam body, and the heat insulating pad is disposed between the roof tile and the top plate. The heat insulation pad is concave, the heat insulation pad corresponds the opening of concave font and roof looks adaptation, and the roof inlays to be established in the recess that the heat insulation pad corresponds the concave font, and the height of heat insulation pad can be according to the fall setting between roof and the heat preservation acoustic celotex board, makes the bottom of heat insulation pad be close to the heated board, and self-adhesion waterproofing membrane is spread and is pasted on the upper surface of heat preservation acoustic celotex board or also is spread simultaneously on the upper surface of heat insulation pad. Then, the self-tapping screw sequentially penetrates through the roof tile, the self-adhesive waterproof coiled material, the heat insulation pad and the top plate, and the roof tile, the self-adhesive waterproof coiled material, the heat insulation pad and the top plate are connected in a locking mode.

Preferably, the heat insulation pad can be made of high-density extruded sheets, foaming PVC or hard foam polyurethane, and has the advantages of convenience in material drawing, low cost and good heat insulation effect. The heat insulation pad can block heat transfer between the purline body and the color steel tile, reduces the heat bridge effect, and ensures that the heat insulation under the roof tile has no dead angle.

In this embodiment, a plurality of inspection through holes are arranged at intervals along the length direction on one side of the bottom plate of the support beam body, and one side of the support beam body with the inspection through holes is arranged above the roof along water slope. The support beam body can be convenient for look for the weeping point of roofing in the use through setting up the inspection through-hole. Specifically, if the color steel tile leaks in the service life, the color steel tile can enter the profiled steel sheet from the gap between the adjacent heat insulation and sound insulation plates, no hole exists in the middle of the profiled steel sheet, water can flow onto the bottom plate from the gap between the profiled steel sheet and the vertical plate, and then flows out of the inspection through holes of the bottom plate, and only the water leakage of the inspection through holes and the water leakage of the two support beam bodies are determined, so that the water leakage of the roof tile can be accurately determined. The worker only needs to search the water leakage point on the roof tile above the area, so that the maintenance cost is greatly reduced. When water leakage is found in the conventional method of the existing roof, the roof tile is corroded and rusted, and water is seriously mixed in the heat-insulating layer; in addition, the profiled steel sheet is generally arranged along the whole water slope in a full length way, and the water flowing distance is long, so that the water leakage point is not found well in the conventional method, and the roof tile can only be forced to be replaced again finally, so that the through hole provided by the utility model has the advantages of clear water leakage point and convenience in maintenance. In the embodiment, the top plate, the bottom plate and the vertical plate are made of steel, the thickness is 1.5mm-3mm, the distance between the top plate and the bottom plate is 40mm-300mm, and the width of the top plate is 30mm-100mm. Embodiment III:

referring to fig. 3 and 4, the difference from the second embodiment is that the support beam body is directly used as a bearing main beam in a floor plate of a steel structure, such as a steel structure interlayer on a newly built steel structure building or attic, and the like, and the product can solve the problem of poor sound insulation of the floor plate of the steel structure.

Specifically, in this embodiment, the top plate, the bottom plate and the vertical plate are made of iron, the thicknesses are 3mm-10mm, the distance between the top plate and the bottom plate is 50mm-300mm, and the width of the top plate is 30mm-100mm.

The concrete construction flow is as follows: the two ends of the T-shaped support beam body are fixed on the columns or walls on two sides according to the conventional construction procedure, and the support beam bodies are arranged at certain intervals. According to the interval between two adjacent supporting beam body riser surfaces, adopt the thermal insulation acoustic celotex board of same width to pack into between two supporting beam bodies, then buckle the heat insulating mattress on the roof of supporting beam body, then install the bedding board such as cement fiberboard, mat formation such as timber apron etc. at last.

The prior art has the problem that the prior steel structure floor plate generally adopts I-steel, C-steel or square tubes as supporting beams. The structural characteristics of the I-shaped steel beams enable the heat-insulating sound-insulating plate to be incapable of being plugged between two adjacent I-shaped steel during installation; when the C-shaped steel or the square pipe is used as a beam, a bottom plate which simultaneously plays a supporting role with two ends of the heat-insulating sound-insulating plate is absent between the adjacent C-shaped steel or square pipes, so that the heat-insulating sound-insulating plate cannot be placed, a supporting backing plate is required to be independently arranged below the C-shaped steel or the square pipe, and the cost of labor and materials is increased; in addition, the square tube has a hollow structure and poor sound insulation.

When the heat-insulating and sound-insulating plate is installed, one side of the heat-insulating and sound-insulating plate can be plugged between the vertical plates of the two support beam bodies and is vertically placed on the bottom plate in a manner of being closely attached to the vertical plates, so that the heat-insulating and sound-insulating plate is tightly connected with the support beam bodies, and gaps are not formed between the heat-insulating and sound-insulating plate and the support beam bodies, so that sound insulation between an upper room and a lower room is better; the heat insulation pad also has a flexible material with heat insulation and sound insulation functions, and has the functions of buffering and noise reduction when the floor is stepped on in the later stage. Therefore, compared with the support beam system of the conventional method, the T-shaped support beam system has better sound insulation and noise reduction functions, and meanwhile, the high tightness of the T-shaped support beam system also strengthens the heat insulation performance between the upper layer and the lower layer, so that the use efficiency of the air conditioner is improved.

In this embodiment, because the supporting beam body is used as the roof beam, the model of the specification that needs to adopt thicker intensity higher, so can adopt hot rolling or hot extrusion integrated into one piece's mode production to the edge of roof and the edge of bottom plate both sides all are equipped with the hem of bending to riser direction, make the anti-bending force of supporting beam body stronger, the supporting intensity is better.

The beneficial effects are that:

most materials of the system can be produced in a factory and assembled on site, so that the on-site operation area is reduced. The construction mode of fixed-length production and then on-site assembly is adopted from the supporting beam body to the heat insulation and sound insulation plate, the profiled steel plate, the heat insulation pad and the self-adhesive waterproof coiled material, and each part is accurately aligned and tightly connected, so that the artificial uncontrollability is reduced. Meanwhile, the assembly method reduces the construction difficulty, greatly improves the installation speed and saves a lot of labor cost.

The heat insulation pad in the system has a flat outer surface, so that the self-adhesive waterproof coiled material can enclose a large U-shaped water guide groove between the heat insulation and sound insulation plate and the adjacent heat insulation pad, and has a structural waterproof effect essentially, and the self-adhesive waterproof coiled material has enough guarantee as the protection of some water leakage. The conventional method is to spread the heat-insulating layer to the same height as the top surface of the purline, and then use a waterproof coiled material to spread and paste along the water slope direction, wherein each coiled material in the method needs to be pasted, and the pasting position cannot ensure good waterproof performance due to various factors. In addition, the arrangement of the checking through holes seems to reduce the tightness of the roof, but the water leakage can be prevented from gradual change by timely finding, so that the permanence of the waterproof system can be ensured. So roofing tile, self-adhesion waterproofing membrane, the inspection through-hole of this system can play waterproof, water conservancy diversion and the three aspect function of early warning respectively, and waterproof performance is better and more permanent than the traditional way.

In summary, the steel structure supporting beam and the supporting system for the building have the advantages of reducing cost, saving space and improving waterproof performance, can solve the problem of poor sound insulation of the conventional steel structure floor plate, and have good social and economic benefits.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
