Wherein, the steel bar truss building carrier plate 2 can realize exempting from formwork construction floor, simultaneously, and the die block in the steel bar truss building carrier plate 2 can be dismantled and can cyclic utilization, and after the die block was demolishd to steel bar truss building carrier plate 2, its bottom molding face is better, need not the later stage and carries out top fitment like the furred ceiling to prevent the indoor height of this assembled steel structure building of loss.
It can be seen that the steel bar truss floor carrier plate 2 not only can improve the construction quality, but also can make the indoor height of the assembled steel structure building higher, and increase the indoor space.
The design and construction of the steel bar truss floor support plate 2 can refer to construction specifications such as 'steel bar truss floor support plate' and 'composite floor slab design and construction specification'.
As shown in fig. 2, the steel bar truss floor support plate 2 comprises end vertical ribs 20, truss steel bars 21 and a bottom template 23, and the bottom template 23 and the truss steel bars 21 are detachably connected together through plastic fasteners 22. Wherein the plastic fastener 22 is a fastener commonly used in construction.
As shown in fig. 2, the steel bar truss deck 2 and the beams 11 in the steel frame support structure 1 may be connected together by welding the end studs 20 to the beams 11.
As shown in fig. 2, when the gap between the bottom formwork 23 and the steel beam 11 is greater than 1 mm, the gap between the bottom formwork 23 and the beam 11 should be blocked by an iron sheet 24 in order to prevent slurry leakage during construction.
As shown in fig. 3, when two adjacent steel bar truss floor support plates 2 are connected together, if the gap between the bottom templates 23 in two adjacent steel bar truss floor support plates 2 is greater than 1 mm, the gap between the bottom templates 23 and the bottom templates 23 should be plugged by an iron sheet 24 in order to prevent slurry leakage during construction.

In actual construction, when the peripheral base wall of the fabricated steel structure building is made of the ALC plate 3, because the ALC plate 3 is made of a rigid material, and a large amount of steel materials adopted by the fabricated steel structure building have lower rigidity and higher flexibility than the ALC plate 3, the connection between the ALC plate 3 and the steel frame supporting structure 1 of the fabricated steel structure building should be connected by adopting the steel pipe anchors 8, as shown in fig. 4, the steel pipe anchors 8 can ensure the connection strength and simultaneously can enable the wall and the steel frame supporting structure 1 to generate coordinated deformation so as to prevent the fabricated steel structure building from being damaged due to rigid extrusion.
Further, the connection between the ALC board 3 at the periphery of the fabricated steel structure building, i.e., the ALC board 3 at the exterior wall, and the beams 11 in the steel frame support structure 1 may be connected together by steel pipe anchors 8. Specifically, as shown in fig. 4, the beam 11 may be welded with angle steel 6, between the angle steel 6 and the ALC plate 3, the angle steel 6 is connected with a steel pipe anchor 8 through a sliding plate 7 and an anchor bolt, and a gap between the ALC plate 3 and the beam 11 at the outer wall may be filled with a foaming agent, a polyethylene rod and a sealant.

When the height of the ALC plate 3 is greater than 24 meters, the connection mode of the ALC plate 3 can be designed singly according to a construction chart set in order to realize coordinated deformation while the assembled steel structure building meets the strength requirement.
When the assembled steel structure building is subjected to lateral force, the lateral displacement of the steel frame supporting structure 1 and the lateral displacement of the steel bar truss floor supporting plate 2 are large. Because the steel frame supporting structure 1 is connected with the wall body, the steel bar truss floor supporting plate 2 is also connected with the wall body, and the rigidity of the ALC plate 3 in the wall body is high, the wall body and the steel frame supporting structure 1 and the wall body and the steel bar truss floor supporting plate 2 can be coordinated and deformed in order to prevent the wall body from being damaged when being subjected to lateral force, and the steel frame supporting structure 1 and the steel bar truss floor supporting plate 2 can not be extruded to damage the wall body in the lateral displacement process.
Further, in order to make the wall body and the steel frame support structure 1 and the wall body and the steel bar truss floor support plate 2 capable of being deformed in a coordinated manner, the connection mode between the rest part of the ALC plate 3 except the bottom part in the wall body and the steel frame support structure 1 can be flexible connection, and the connection mode between the ALC plate 3 in the wall body and the steel bar truss floor support plate 2 positioned on the steel frame support structure 1 can be flexible connection.

In the present embodiment, the diagonal braces 12 in the steel frame support structure 1 are box-shaped steel diagonal braces 12.
In the actual construction process, the box-shaped steel diagonal bracing 12 should be coordinated with the assembled steel structure building to prevent the box-shaped steel diagonal bracing 12 from being arranged at the door and window opening position.
The wall body further comprises an air adding block and an autoclaved sand-lime brick, and the air adding block is enclosed at a position corresponding to the diagonal bracing 12 on the steel frame supporting structure 1. Autoclaved sand-lime bricks are enclosed on the steel frame supporting structure 1 at the area corresponding to the toilet in the building.
The design and construction of the aerated block and the autoclaved sand-lime brick can also refer to construction atlas such as autoclaved aerated concrete block, plate structure, autoclaved aerated concrete slab and the like.
