However, the steel structural components for constructing the frame-type building are generally constructed by a construction method of transporting the components to the site for assembly, the number of the components is large, the time and labor are wasted in the process of on-site installation and disassembly, and if the wallboard structural frame is installed in advance, the assembly efficiency of the steel structure is influenced because the size is large and the transportation is inconvenient.
Example 1:

When in use, the utility model can be unfolded directly. The method has the advantages that excessive component installation is not needed, the building time of the frame type building is greatly shortened, and the building efficiency is improved. Specifically, the method comprises the following steps:
this building steel structure includes a plurality of prefabricated steel columns of corner 2 of connecting on bottom plate 1 of erectting, is equipped with a plurality of articulated joints 3 on the prefabricated steel column of corner 2. The height direction interval distribution of a plurality of hinged joint 3 edge angle prefabricated steel column 2 has folding wall supporting component 4 through just to 3 swing joint of hinged joint 3 swing joint that set up between two adjacent corner prefabricated steel column 2, and folding wall supporting component 4 can follow a corner prefabricated steel column 2 and around a plurality of hinged joint 3 pivots to radially draw close to angle prefabricated steel column 2 and accomplish the shrink. Wall supporting component 4 can also can draw close the shrink in the prefabricated steel column 2 of a plurality of corners that lie in the steel construction corner after the shrink promptly to contract into a long structure with whole frame-type building, have less area's characteristics, the transportation of being convenient for, and the integral type structure need not carry out on-the-spot dismouting, has improved frame-type building's the efficiency of buildding.
The invention is characterized in that: the end part of the wall surface supporting component 4 is connected with the corner prefabricated steel column 2 in a hinged mode through the hinge joint 3, the wall surface supporting component 4 and the corner prefabricated steel column 2 do not need to be assembled temporarily, and the mounting efficiency of the steel structure is improved. Simultaneously, the wall supporting component 4 of being convenient for draws close to corner prefabricated steel column 2 after contracting, accomplishes the integral type shrink, and area is little, the transportation of being convenient for. Specifically, the method comprises the following steps:
articulated head 3 all includes a plurality of universal set of joints subassembly 301, and universal set of joints subassembly 301 all includes along the first pivot 302 that rotates of corner prefabricated steel column 2 side direction level extension. That is, the first pivot 302 is vertically disposed with the corner precast steel column 2, and the first pivot 302 is radially rotatable in the horizontal extending direction. The end of the first rotating pivot 302 is movably connected with a rotating ball 303, and the rotating ball 303 is movably connected with a second rotating pivot 304. Since the rotating ball 303 can rotate at any angle, the second rotating pivot 304 can rotate at any angle around the first rotating pivot 302 along with the rotating ball 303, and the above structure is similar to a common universal joint. The second pivot 304 is connected to the side end of the wall surface supporting component 4, so that the wall surface supporting component 4 can rotate at any angle relative to the corner prefabricated steel column 2.
The invention is also characterized in that: wall supporting component 4 after folding conveniently transports to wall supporting component 4 can expand the inner frame that forms the steel construction fast, and the integral type structure has reduced a plurality of interior wall frame subassemblies's assemble duration, improves engineering efficiency. Specifically, the method comprises the following steps:
the wall support assembly 4 includes a plurality of parallel horizontal steel column assemblies 401 and a plurality of vertical steel columns 402 perpendicular to the horizontal steel column assemblies 401. Preferably, the horizontal steel column assembly 401 is detachably connected to the end of the second pivot 304.
The intersections of the horizontal steel column assemblies 401 and the vertical steel columns 402 are hinged to each other by pivot pivots 403. A plurality of horizontal steel column assemblies 401 and vertical steel columns 402 form a filling lattice 5 therebetween, which improves the load-bearing capacity of the steel framework. The structure is similar to a folding clothes hanger or a common telescopic door. The expansion is convenient, when not in use, the utility model can be quickly contracted into a limited floor area, and the transportation and carrying are convenient.
In order to maintain the vertical position of the corner precast steel column 2 and the wall surface support member 4 after being unfolded, a position limiting sleeve installing cylinder 305 is provided at the end of the horizontal steel column member 401, and can slide along the radial direction of the horizontal steel column member 401, and the position limiting sleeve installing cylinder 305 can simultaneously install the first rotating pivot 302 and the second rotating pivot 304 which are positioned on a horizontal line. After the corner prefabricated steel column 2 and the wall surface supporting component 4 are adjusted to be vertical, the limiting sleeve installing barrel 305 on the horizontal steel column component 401 is directly slid to the first rotating pivot 302 and the second rotating pivot 304 which are positioned on the same horizontal line at the same time, so that the vertical state between the two is fixed.
In another embodiment, considering the limited mass that the hinge joint 3 can bear, part of the weight of the wall support assembly 4 is distributed to the corner precast steel column 2, specifically:
the connection part of the side wall of the corner prefabricated steel column 2 and the first rotating pivot 302 is provided with a convex socket column 306. The outer ring of the sleeve connection column 306 is provided with a sleeve connection thread 307, and the sleeve connection thread 307 is matched with the inner wall thread of the limiting sleeve installation barrel 305. When the limiting sleeve installation barrel 305 on the horizontal steel column assembly 401 slides to the first rotating pivot 302, the second rotating pivot 304 and the sleeve column 306 which are positioned on the same horizontal line and are covered at the same time, part of the weight of the wall surface supporting assembly 4 is distributed to the corner prefabricated steel column 2, and the overall rigidity of the steel structure building is improved.
Preferably, the first and second pivot shafts 302, 304 have the same cross-section as the collar post 306, which fits within the interior cross-section of the stop collar assembly 305. The smoothness of the running of the stop sleeve barrel 305 is improved.
The assembly unit module in the existing assembly type building technology has the defects of self weight, low assembly degree, low integration degree and the need of welding assembly nodes on site, and the components of the assembly type steel structure are generally prefabricated according to specifications in advance, so that the requirement on steel structure buildings with different specifications is difficult to meet by one set of construction.
The present invention effectively solves the above problems by using the wall surface supporting member 4 which can be changed in length in the horizontal and reverse directions. And greatly improves the assembly efficiency. Specifically, the method comprises the following steps:

When fabricated buildings with different length-width ratios are needed, only the length of the horizontal sleeve steel column 405 sleeved in the horizontal sleeve steel column 405 needs to be adjusted and changed. One set of equipment can be used for randomly building steel structure buildings of various scales, and the applicability of the assembly type building is greatly enhanced. But also can buffer the transverse stress of the steel structure and avoid stress collapse.
In order to ensure sufficient rigidity of the steel structure and avoid the fracture of the connection part of the horizontal sleeve steel column 405 and the horizontal sleeving steel column 406, it is preferable that: the length of the horizontal sleeved steel column 406 sleeved inside the horizontal sleeve steel column 405 is not less than one third of the length of the horizontal sleeve steel column 405.
Meanwhile, in consideration of reducing the number of assembly components of the wall surface support component 4 as much as possible, the horizontal sleeve steel column 405 and the horizontal sleeving steel column 406 which are adjacent to each other and located between two adjacent telescopic units 404 are integrally formed to form an assembly cross rod 407, and the assembly cross rod 407 and the vertical steel column 402 are hinged to each other. The horizontal sleeved steel column 406 at one end of the assembled cross bar 407 is sleeved in the horizontal sleeve steel column 405 of the adjacent assembled cross bar 407. I.e. several assembling rails 407 are connected end to end. The assembling cross bars 407 at the two ends of the horizontal steel column component 401 are respectively connected with the hinge joints 3 with the corresponding horizontal height.
After the horizontal steel column assembly 401 and the vertical steel column 402 of the wall surface supporting assembly 4 are adjusted to be perpendicular to each other, the hinged portion may be stressed to be difficult to maintain the perpendicular state therebetween. Therefore, the assembling cross bars 407 and the vertical steel columns 402 at the hinge joint parts are respectively provided with a vertical limiting component 8 for locking the mutually perpendicular state of the assembling cross bars 407 and the vertical steel columns 402.

After the horizontal steel column assembly 401 and the vertical steel column 402 are adjusted to be perpendicular to each other, the limiting guide groove 802 and the limiting guide strip 803 on the limiting slide block 801 are located on the same straight line. The limit slider 801 is pushed in to clamp the limit guide strip 803 in the limit guide groove 802, and the vertical relation between the horizontal steel column assembly 401 and the vertical steel column 402 is locked.
The invention is also characterized in that: prefabricated filling wall boards 6 are respectively arranged in the filling lattices 5. Prefabricated infilled wall panel 6 is the elastic material that has all around to inlay and get into in the groove. Specifically, the method comprises the following steps:

Not only can improve the rigidity of steel structure building, but also the open slot that i-shaped steel structure formed can provide spacing space for prefabricated infilled wallboard 6. Specifically, the method comprises the following steps: the openings of the i-section steel adjacent to one of the filling lattices 5 are all directed towards the same filling lattice 5 so as to form a limiting frame groove 7 enclosing the deformed hollow plate 601.
