[0038] Further specifically described: Through the design of the strengthening assembly 400, the stable connection between the web bar reinforcement 110 and the bottom formwork 200 can be strengthened, and the situation that the connection is unstable due to the small contact area between the web bar reinforcement 110 and the bottom formwork 200 can be avoided.

[0039] Specifically, there is a distance between two opposite web bar reinforcements 110 in adjacent two groups of the reinforced trusses 100.

[0040] Specifically, two opposite web bar reinforcements 110 in adjacent two groups of the reinforced trusses 100 are welded.

[0041] Further specifically described: The distance between two opposite web bar reinforcements 110 in adjacent two groups of the reinforced trusses 100 can be adjusted appropriately according to actual needs to improve adaptability, and the adjustment is carried out before the wave trough section 111 of the web bar reinforcement 110 is welded to the steel mesh 500.

[0042] Specifically, the steel truss 100 includes an upper chord 120, a lower chord 130 and a cross steel bar 140, and both sides of the upper chord 120 are welded to the web bar 110;

[0043] To be more specific, each group of steel trusses 100 includes an upper chord 120 , two web bars 110 and two lower chords 130 .

[0044] The web reinforcement 110 also includes a peak section 112 integrally formed with the trough section 111, the outer side of the lower end of the peak section 112 is welded to the lower chord reinforcement 130, the cross-rebar 140 passes from the inner side of the peak section 112 of one group of web reinforcements 110 to the inner side of the peak section 112 of another group of web reinforcements 110, and the top end of the cross-rebar 140 is welded to the bottom end of the upper chord reinforcement 120.

[0045] To be further described in detail: the trough section 111 is parallel, the crest section 112 is vertically inclined, the crest section 112 and the trough section 111 are integrally formed, and the trough section 111 is arranged in the bottom template 200; the design of the cross-bar 140 is convenient for hoisting, and there are two of them.

[0046] Specifically, the connecting sleeve 310 includes a half ring 311, the half ring 311 and the lower chord rib 130 are sleeved, the half ring 311 and the lower chord rib 130 are welded, one end of the half ring 311 is integrally formed with a connecting rod 312, the other end of the connecting rod 312 is horizontal, the other end of the connecting rod 312 is threadedly connected to the threaded tube 320, and the connecting rod 312 and the threaded tube 320 are sleeved and connected.

[0047] To further explain in detail: one end of the connecting rod 312 is horizontal, and the other end is inclined, and it is integrally formed with the half ring 311 on the same side, thereby strengthening the connection strength between the half ring 311 and the connecting rod 312.

[0048] Specifically, the two connecting rods 312 in the same group of the connecting assembly 300 correspond to a threaded barrel 320, and the ends of the two connecting rods 312 have threaded rings with opposite directions. The inner walls of the threaded barrel 320 have threaded holes at both ends that match the threaded rings on the same side.

[0049] To be further described in detail: a handheld tool is used to clamp the threaded barrel 320 and twist it, the threaded barrel 320 rotates, and the threaded barrel 320 is threadedly connected to the connecting rods 312 on both sides, and the connecting rods 312 are limited by the half ring 311 and the steel truss 100. The connecting rods 312 cannot rotate circumferentially with the threaded barrel 320, and can only move axially along the threaded barrel 320, so as to adjust the spacing between the connecting rods 312 on both sides, thereby also adjusting the spacing between the steel trusses 100.

[0050] Specifically, it further includes a steel bar mesh 500, which comprises longitudinal steel bars 510 and transverse steel bars 520. The longitudinal steel bars 510 and the transverse steel bars 520 are welded and fixed crosswise, and the bottom end of the trough section 111 is welded to the transverse steel bars 520.

Therefore, the strengthening component 400 and the steel bar mesh 500 will not interfere with each other.

[0052] When the reinforced steel truss thin-walled plate with adjustable truss spacing in the embodiment of the present application is actually used: Connect multiple groups of steel trusses 100 and connecting components 300 according to the above structure. When it is necessary to adjust the spacing of the steel trusses 100, there is one staff member in the span direction of each steel truss 100. Hold the tool to clamp the threaded cylinder 320 and turn it. The threaded cylinder 320 rotates. The threaded cylinder 320 is threadedly connected to the connecting rod 312. Since the connecting rod 312 and the half collar 311 are integrally formed, and the half collar 311 is welded to the lower chord bar 130, stabilize the steel truss 100, so that the steel trusses 100 can only approach or move away from each other, thereby the distance between the steel trusses 100 can be adjusted. In addition, adjacent web bars 110 of adjacent steel trusses 100 can also be welded according to requirements.

[0053] Then weld the steel truss 100 and the steel bar mesh 500, and finally pour concrete into the steel truss 100 and the steel bar mesh 500 to obtain a thin-walled plate. The strengthening component 400 is also poured synchronously, which strengthens the connection strength between the steel truss 100 and the bottom formwork 200.
