[0002] Steel truss floor deck, also known as steel truss formwork, is a composite structural system formed by processing the main load-bearing steel bars in the floor slab into steel trusses using special equipment in the factory, and then welding the steel trusses and galvanized steel plates into one. When used, it can be built on the roof and concrete can be poured directly on top to form a steel truss concrete floor.

[0003] However, there are some problems with the prior art: when the existing steel trusses are hoisted, multiple groups of steel truss floor decks are usually stacked and tied, and then a support column is inserted from the middle for hoisting. However, the steel truss floor decks after production are large in size and inconvenient to transport and hoist. If they are transported and hoisted after disassembly, they are usually fixed by spot welding when assembled on site, which is not easy for ordinary workers to operate and is inconvenient to assemble on site. Therefore, we propose a steel truss floor deck that is easy to hoist. Utility Model Content

[0033] The connecting component 11 includes a first positioning block 12 and a second positioning block 1201. The first positioning block 12 and the second positioning block 1201 are both welded to the upper surface of the bottom template 1. The first positioning block 12 is rotatably connected to the fixed plate 13 through a hinge. The bottom of one end of the fixed plate 13 is fixedly connected to a connecting block 16. A limiting groove is provided in the second positioning block 1201, and the connecting block 16 is inserted into the second positioning block 1201 through the limiting groove.

[0034] By connecting the components 11 and the lifting ring 8, the lifting ring 8 can be used to conveniently lift the steel truss floor deck. By using the connecting components 11, ordinary workers can also easily complete the assembly of the steel truss 2 and the bottom formwork 1 on site.

[0035] Furthermore, the steel truss 2 includes an upper-chord steel bar 4 and two groups of lower-chord steel bars 3, both ends of the two groups of lower-chord steel bars 3 are fixedly connected between the first positioning block 12 and the second positioning block 1201, both ends of the lower-chord steel bars 3 are fixedly connected with two groups of flank steel bars 5, the upper-chord steel bar 4 is fixedly connected between the two groups of flank steel bars 5, and flank bending bars 6 are welded on both sides of the middle part of the upper-chord steel bar 4, and the two ends of the two groups of flank bending bars 6 are respectively fixedly connected to the opposite sides of the two groups of lower-chord steel bars 3.

[0036] By using multiple groups of flank steel bars 5 and flank bending bars 6, the upper chord steel bars 4 and the lower chord steel bars 3 can be connected and fixed, and the steel truss 2 can be fixed on the bottom formwork 1 through the connecting assembly 11.

[0037] Furthermore, two sets of connecting plates 7 are fixedly connected to one side of the bottom template 1, and a second threaded hole is opened on the connecting plate 7. A connecting hole 10 is opened on one side of the bottom template 1, and the connecting hole 10 is arranged corresponding to the connecting plate 7. A first threaded hole is opened at the bottom end of the bottom template 1 at the connecting hole 10, and a first bolt 9 is threadedly connected to the connecting hole 10.

[0041] How it works

[0042] When the utility model is in use, the limit block 14 is first moved out of the connecting block 16 by using the sliding rod 15, so that the fixing plate 13 can be rotated and opened along the hinge, and then the steel truss 2 is removed from the bottom template 1, and then the bottom template 1 and the steel truss 2 are lifted respectively by using the lifting ring 8, and then the steel truss 2 is placed in the first positioning block 12 and the second positioning block 1201, and the fixing plate 13 is closed to wrap the two ends of the lower chord steel bar 3, and finally the sliding rod 15 is moved to clamp the limit block 14 into the connecting block 16 to fix the steel truss 2.

[0043] The utility model solves the problem that the steel bar truss floor deck is large in size, inconvenient to transport and hoist, requires spot welding to fix, is difficult for ordinary workers to operate, and is not convenient for on-site assembly through the connection assembly 11.
