[0027] Embodiment 1

[0028] like Figure 1-Figure 6As shown, a latch-type fixed support is installed in a detachable steel truss floor deck system. The latch-type fixed support includes a connecting body 1, a fixing body 2, and a latch 3; the connecting body 1 is in the shape of a plate, and threaded holes 4 are provided at both ends, and it is fixed on the bottom mold of the detachable steel truss floor deck system through the threaded holes 4; the fixing bodies 2 are in a plurality, evenly spaced and vertically fixed on the connecting body 1; in this embodiment, two groups of fixing bodies 2 are symmetrically fixed at both ends of the connecting body 1; the fixing body 2 is provided with a first socket 53, a second socket 63, and a bayonet 71, wherein the bayonet 71 is provided between the first socket 53 and the second socket 63; the latch 3 is inserted into the first socket 53 and the second socket 63 in sequence, and a fixed area is formed between the latch 3 and the bayonet 71, which is used to fix the steel bars of the steel truss floor deck system.

[0029] In this embodiment, the connecting body 1 and the fixing body 2 are integrally formed; or, the two can be divided into two independent parts and then welded into a whole.

[0030] In this embodiment, the fixed body 2 includes a first plug plate 5, a second plug plate 6, and a clamping plate 7, which are integrally formed or can be divided into three independent parts for welding and assembly, and the whole is in a concave shape; the first plug plate 5 and the second plug plate 6 are symmetrically arranged at the left and right ends of the clamping plate 7; the first plug plate 5 is provided with a first raised section 51 and a first recessed section 52, which are staggered front and back to form a first socket 53 between each other; the second plug plate 6 is provided with a second raised section 61 and a second recessed section 62, which are staggered front and back to form a second socket 63 between each other; the first raised section 51 and the second raised section 61 are in the same vertical plane, and are arranged opposite to each other; the first recessed section 52 and the second recessed section 62 are in the same vertical plane, and are arranged opposite to each other; the clamping port 71 is arranged on the clamping plate 7.

[0031] In this embodiment, the bayonet 71 is V-shaped, so that when the steel bar is placed in the bayonet 71, it is easy to fix the steel bar in place. At the same time, the V-shaped structure design cooperates with the pin 3 to make the structure more stable and the steel bar can be fixed more firmly.

[0032] In this embodiment, the latch 3 is plate-shaped and has a right-angle trapezoidal shape as a whole. A circular arc surface is provided at the bottom of the latch 3; when the steel bar is inserted into the fixing area between the latch 3 and the bayonet 71, the circular arc surface is located at the upper side of the steel bar; thus, the steel bar can be fixed and locked more firmly, and the structural design is more reasonable.

[0033] In this embodiment, a clamping protrusion 31 is fixed on the front end surface of the bolt 3, which is pyramidal or hemispherical. When the bolt 3 is inserted into the first socket 53 and the second socket 63 in sequence, the clamping protrusion 31 is located on the side of the first socket 53 or the second socket 63, or on the side of the first protrusion section 51 or the second protrusion section 61. In this way, it is convenient to lock the bolt 3 and enhance the structural stability. This is a conventional technology and will not be elaborated on.

[0034] The working principle of this embodiment is: when the steel truss floor deck is constructed (after the connecting body 1 is fixed to the bottom mold), the truss steel bar is inserted into the bayonet 71, and then the pin 3 is inserted into the first socket 53 and the second socket 63 in sequence, so that the steel bar is locked in the fixed area between the pin 3 and the bayonet 71.

[0035] The beneficial effect of this embodiment is that the installation and fixing method of the bolt-type fixing support is convenient and quick, and is more stable and reliable than the existing buckle fixing method with slippage and falling off. At the same time, the bolt-type structure is also easy to disassemble and assemble, and can be installed on site. By setting the bayonet 71 into a V shape, it is easy to fix and position the truss steel bars and install them, and the structure can be made more stable.

[0036] Embodiment 2

[0037] The difference between this embodiment and the first embodiment is that the latch-type fixing support further includes an auxiliary pad 8 , and the auxiliary pad 8 is fixed to the bottom of the connecting body 1 .

[0038] In this embodiment, the auxiliary pads 8 are plastic pads; there are two groups of auxiliary pads 8, which are fixed at both ends of the bottom of the connecting body 1, and the fixing method can be glue or fasteners such as screws.

[0039] The beneficial effect of this embodiment is that by arranging the plastic pad, the utility model can also ensure that the metal part of the floor decking is not exposed after the construction is completed, that is, after the formwork is removed, the structural design is more reasonable, and the construction quality is guaranteed.

[0040] Embodiment 3

[0041] The difference between this embodiment and the first embodiment is that the connecting body 1, the fixing body 2 and the plug 3 are all made of galvanized material.

[0042] The beneficial effect of this embodiment is that by using galvanized materials for each component, the strength of the present invention is higher than that of the existing support and can better meet the process requirements.

[0043] Advantages of the utility model:

[0044] 1. The fixing method is convenient, reliable and stable, and can be installed on site;

[0045] 2. Higher strength, better able to meet process requirements;

[0046] 3. Simple structure, easy to disassemble and assemble.
