But in the excellent agent structure of aforesaid post, post 2 extends to floor from following floor, the post 2 of each floor at grade, therefore if determine post 2 positions according to the room configuration of certain one deck, also stipulate thus post 2 positions of remainder layer, so also just limited the degree of freedom of every layer of plan.And then, for example in Figure 37, even under 2 layers post 2, wall peristome 9 is set, also because of having in its position and 1 layer of identical post 2, so owing to the existence of this post 2 produces wall peristome 9 inconveniences such as grade that expectation can't be set.
In addition, as in the above-mentioned excellent agent structure of post, shown in above-mentioned each document, on post 2, generally adopt rectangular steel tube.Figure 38 adopts the plane of the frame structure of the post 2 that is made of rectangular steel tube for expression and constitutes.The post 2 that is made of rectangular steel tube has identical cross section performance on directions X and Y direction, therefore by adopting this post 2, can form a post 2 bear directions X and Y direction two to the twocouese frame structure of level load.
But, as mentioned above, a post 2 all possesses on directions X and Y direction in the twocouese frame mechanism body of horizontal endurance, for example in Figure 38, between the post 2a of centre and relative therewith post 2b, necessarily beam 3e need be set, and post 2c also be set always at the beam 3f of directions X and the beam 3g cross part of Y direction.Therefore, when the centre of location of design post 2 and beam 3, strengthened the restriction in the design.
In addition, in this twocouese frame structure, be to improve the cross section performance of post 2, must strengthen the sectional dimension of this post 2, but in this case, as shown in figure 38, post 2 is outstanding to the width of beam 3, drawback such as post can't be received in the wall body and produce.
And then rectangular steel tube has the cross section of blocking shape, is fished beam 3 on its side therefore, need carry out complicated processing to the mating face, or weld various accessories.
The present invention develops in order to improve the problems referred to above in the existing agent structure, its purpose is, a kind of agent structure of steel frame building thing is provided, has improved the design freedom height of post and beam configuration, therefore reduced the restriction in the configuration of room configuration and peristome.And the objective of the invention is to, in the aforementioned body structure, guarantee enough structure endurance, and then effectively form the connected structure of each parts, and improve application property according to the parts Cross section Design of economy.
Summary of the invention
For reaching above-mentioned purpose, the basic comprising of the agent structure of steel frame building thing of the present invention constitutes more than 2 floors for the post that will be made of the steelframe material and beam engage, it is characterized in that, bear the length of material of the post of normal load and level load and carved up each floor, and have precedence over the excellent engagement state of post of post by the continuity that post and beam is bonded into the beam between each floor, the post of each floor can be configured to respectively on the optional position of beam individually, simultaneously the junction surface of above-mentioned post and beam rigidly connects abreast by the material direction of principal axis with the strong direction of principal axis of post and beam and closes, and forms a unidirectional frame construction that possesses horizontal endurance on the material direction of principal axis of each beam.
According to this basic comprising, because of having run through beam between the post of each layer and the post, so need not as the excellent agent structure of existing post, to make the post position consistency of each layer, so the position of the post of each layer of conversion, for example can improve in the degree of freedom that is provided with under 2 layers the post in the designs such as peristome such as window.And the radical of the post of last floor reduces to and is less than the down radical of the post of floor, and therefore design plane plan more freely can be realized simultaneously improving the application property of the operation of inserting post and reduce component costs.
In addition, according to above-mentioned basic comprising, because of having constructed agent structure by the strong direction of principal axis of coupled column and the consistent unidirectional framework of material direction of principal axis of beam, so at least only having engaged beam in one direction and just be enough on a post, and need not as the two-way frame at the beam that engages on the post more than the both direction.Its result need not the bight or the T font portion configuration post that must intersect at the beam of the beam of directions X and Y direction, thereby can be to the beam of directions X then on the optional position of its directions X, on the other hand, to the beam of Y direction then on the optional position of its Y direction, the configuration post.Thus, positions such as peristome for example in planar design, have been pre-determined, so can on position in addition, dispose structural design drawing post, that degree of freedom is very high.And, also can design corner portion do not have post, cross section is the layouts such as window of L font.
And, in order to improve performance, should only on the material direction of principal axis of beam, increase the sectional dimension of post, and need not to increase at the width of beam as above-mentioned unidirectional frame construction, therefore also be easy to post is received in the wall body.
And then, agent structure of the present invention is as the formation of the splitlevel agent structure that relates to the plural above-mentioned agent structure body of combination, can also adopt first agent structure, the depth of beam second agent structure body disposed adjacent different with the floor gap that has a part at least with the above-mentioned first agent structure body, the beam of the foot of these two agent structure bodies is connected by one separately from each other with the beam of topmost each other, simultaneously joins formation on the beam of each floor gap of each agent structure body at the post that preferential mode will be common to two agent structure bodies with beam on the adjacent portions of two agent structure bodies.
In addition, as other formations that relate to identical splitlevel agent structure, can also adopt by the staggered floor section the depth of beam second agent structure body disposed adjacent different with the above-mentioned first agent structure body with the floor gap of the first agent structure body and at least a portion, the beam of the foot of these two agent structure bodies is connected by one separately from each other with the beam of topmost each other, on above-mentioned staggered floor section, stand simultaneously and establish through post, the beam of each floor gap of two agent structure bodies extends to above-mentioned staggered floor section, thereby mode preferential with beam or that post is preferential joins the formation on the above-mentioned through post to.
Constitute according to these, each agent structure body that the depth of beam of floor gap is different has constituted the preferential frame structure of beam respectively, therefore carries out structural calculation easily on each agent structure body, thereby parts design transfiguration is easy.And, even at the stair of the coupling part that is arranged at two agent structure bodies be arranged on the depth of beam around its stair etc. design variation takes place, also needn't carry out complicated specification conversion to the parts of periphery, and can mobile simply post and the position of beam.
Particularly, when employing connects the formation of two agent structure bodies by the through post that is arranged at the staggered floor section, the structure independence of each agent structure body becomes clearer and more definite, and the outer wall that the staggered floor section is shaken in the vibration when avoiding owing to earthquake easily simultaneously breaks away from situations such as agent structure body.
Cross section structure as the critical piece that constitutes the aforementioned body structure, beam preferably by the web that possesses setting and up and down the H shape steel of 2 flanges constitute, and the post of bearing normal load and level load is preferably by having the steel of web of open tee section or the assembly of these steel constitutes in a strong axial part at least.
And, connected structure as these posts and beam, preferably on the flange of beam, form a plurality of bolts hole with predetermined distance, and weld the fish plate that its size is no more than the flange width of beam in the end of post, therefore on this fish plate, also form bolt hole, and by above-mentioned each bolt hole with high-strength bolt the be spirally connected fish plate of post and the flange of beam, post and beam are engaged by steel.
The employing of and connected structure selected according to this parts can be transferred to low cost with the post and the beam that possess necessary cross section performance, and the joint operation each other of these parts also becomes simpler, thereby has improved application property.
In the aforementioned body structure, for will be on top or lower bond the sidepiece (so-called panel section) of beam of post put more energy into, the parts of putting more energy into that are connected between the last lower flange of this beam preferably will be installed in the scope of the strong axial sectional dimension that meets above-mentioned post at least.As the parts of putting more energy into, the stiffener on the side of the last lower flange that is fixed by welding in beam and web, can also the reinforcing rib identical with above-mentioned stiffener be set on being the parts of channel shaped in the cross section on the side of lower flange on the beam and web adding.This strength parts can also form the unit that separates with beam, and are screwed to by means of high-strength bolt on the recess of beam.
In addition, according to the aforementioned body structure, need not beam to be rigidly connected each other and close in corner portion and T word portion.Therefore, mutually orthogonal beam can carry out and will be fixed in the butted part of web of the stiffener of side of a curb girder and another curb girder by adding, so-called dowelled joint that be spirally connected with high-strength bolt in the continued access plate of this butted part each other.Thus, beam joint each other is simple, and can be at outstanding fish plate of the upper and lower of the flange of beam and high-strength bolt etc., so the agent structure body also becomes simple with being connected of wall material or floor etc.
Moreover, be configured to outer structural requirement according to post, have the beam of having to quadrature and rigidly connect each other and close, so that the situation of the flexural stress of transfer beams.In this case, the butted part of lower flange is also added the continued access plate on beam, thereby can engage by high-strength bolt.
When not wanting in that the upper and lower of the flange of beam is prominent when establishing continued access plate and high-strength bolt, can with the cross section L word with the web that on the material direction of principal axis of each beam, extends the amount of given size, the T word, or the quadrature web that is welded of crosswise, pass through the quadrature flange that a steel plate forms respectively with each flange of the upper and lower of the amount of extension given size on the material direction of principal axis of each beam, connect by welding the quadrature beam element that forms that is fixed as one in advance, quadrature web and quadrature flange with this quadrature beam element, with the web and the flange of each beam, carry out high-strength bolt by the continued access plate respectively and connect to rigidly connect and close.If adopt this syndeton, also flexural stress can be delivered to beam orthogonal part each other, be used for fished beam plate and the orthogonal part that can not be projected into beam such as bolt each other simultaneously, therefore also be easy to post upright be located at this orthogonal part under or directly over.
Therefore in addition, according to the aforementioned body structure, the relative beam of post of bearing level load rigidly connects and closes, and for the studding of not bearing level load, then beam carries out the preferential dowelled joint of beam for well relatively.Thus, can reduce the sectional dimension of studding, also can hold the junction surface of studding and beam simultaneously compactly.
In addition, in the aforementioned body structure, connect, can in the horizontal structure face that is surrounded by beam, form ground by will flange carrying out high-strength bolt from the outstanding floor fish plate carrier of the acies portion on the floor that constitutes by precast concrete to beam.According to this structure, needn't carry out complicated processing and just easily the floor be joined on the beam, utilize the interior rigidity of face on floor self simultaneously, the sufficient rigidity on the horizontal plane that can guarantee to be surrounded by beam.Also after floor construction to this floor, its floor can be set on the beam as activity bases and with the post of this floor is upright, therefore also have the good working performance.
In addition, in the aforementioned body structure, can outer wall materials be installed on the flange of beam by suitable installing component.In this case, exempt from the state in the outside of face, or support the outer wall parts with the state that separates with the main body structure face outside to be connected to the agent structure that constitutes by post and beam.Perhaps, outer wall materials can be installed in the main body structure face that constitutes by post and beam.
In addition, in the aforementioned body structure, can also be formed for the section of bond post at the middle body on the width of beam, side edge portions is formed for the section of joined floorboards or outer wall materials, forms bolt hole with predetermined distance on above-mentioned each section in upright arrangemently.According to this structure, because of on the flange of beam, having divided the section that is used for bond post and be used for the section of joined floorboards and outer wall materials, thereby can avoid being used for the various board types and the mutual interference of bolt type phase of these joints.Therefore, can with the position that situation is irrespectively set post that holds of floor and outer wall materials, thereby further improve the design freedom of structure.
For the foot of aforementioned body structure, it can be joined on the grade beam that is made of steel concrete.This grade beam possesses: be configured along a pair of up and down cross main-bar of the direction of principal axis of grade beam, in that the direction of principal axis of grade beam is separated by a certain interval, and connect many stirrups between the above-mentioned cross main-bar, be configured in the abdomen muscle of the pars intermedia of above-mentioned stirrup as required, and on the bonding station of post, disposed 2 one group the stone bolt that is disposed at the width of grade beam with separated by a certain interval, so that stride across the cross main-bar of upside.
By formation base beam like this, on the agent structure body of 2 layers of building or 3 layers of building, needn't too increase the width of grade beam, and save quantity of reinforcement and amount of concrete, can guarantee the practical sufficient underlying strength of.And even do not adopt complicated template auxiliary, the stone bolt that also can only will be used for bond post by the simple operation of necessity is configured in the optional position, thereby has improved the workability of template processing.
For the foot of aforementioned body structure, also these can be joined on the grade beam that constitutes by H shape steel, and cover around this grade beam by concrete.
According to this structure, grade beam also can engage with the identical side of beam with the post of superstructure with the joint of post, therefore can unify job content, thereby realizes the efficient activity of field operation.And, compare with the method for the grade beam of constructing steel concrete system at the scene, can make the operation of the top level of formulating grade beam and the adjustment operation of punching and the position operation of formulation stone bolt etc. become simple, thereby grade beam can be set at short notice.Uncommon tight bolt hole is because of forming in factory in advance, so also improved construction precision.And then, be cast in grade beam concrete on every side and prevent that this grade beam from getting rusty, increase basic all weight simultaneously, thereby improved stability.
