Description

Technical Field

[0001] The utility model relates to a fine stone concrete steel bar truss floor deck, belonging to the technical field of steel bar truss floor decks. Background Art

[0002] The truss made of steel bars as the upper chord, lower chord and web members connected by resistance spot welding is called a steel truss. The combined load-bearing plate formed by the steel truss and the bottom plate connected by resistance spot welding is called a steel truss floor deck. The steel truss floor deck can be mechanized, which is conducive to uniform spacing of steel bars and uniform thickness of concrete cover, thus improving the construction quality of the floor. The assembled steel truss floor deck can significantly reduce the amount of on-site steel bar binding work, speed up the construction progress, increase construction safety assurance, and achieve civilized construction.

[0003] For example, CN215330825U discloses a steel truss floor decking, which makes the fireproof floor decking combination more closely combined with the concrete floor slab, improves the floor slab strength, avoids the difficulty of steel bar binding and the need to remove the formwork, and the problems of holes and gaps in the floor slab after the formwork is removed after the concrete is poured and formed. The fireproof floor decking combination does not need to be removed, and the concrete floor slab will not leave holes and gaps after the concrete is poured and formed, and the appearance is neat and beautiful. However, although the steel truss floor decking can be exempted from removal, the bottom plate mixed in the concrete will also be used more, which increases the use cost of the steel truss floor decking, and the bottom plate after splicing is prone to certain misalignment, which easily causes concrete to leak from the joints of the bottom plate.

[0024] Example 1: Please refer to Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A fine stone concrete reinforced truss floor decking plate comprises a base plate 1, a bottom steel bar 2 is fixedly connected to the top of the base plate 1, a V-shaped steel bar 3 is fixedly connected to one side of the bottom steel bar 2, a top steel bar 4 is connected to the top of the V-shaped steel bar 3, a protrusion 5 is provided on the side of the base plate 1, a rubber sealing pad 6 is provided at one end of the protrusion 5, a positioning seat 7 is fixedly connected to the bottom of the base plate 1, a positioning rod 8 is connected inside the positioning seat 7, a push plate 9 is fixedly connected to one end of the positioning rod 8, a slider 10 is connected inside the push plate 9, a crank 11 is connected inside the slider 10, a fixed shaft 12 is connected inside the crank 11, and a handle 13 is connected to one end of the crank 11.

[0026] Specifically, a clamping plate 14 is provided on the base plate 1 at the other end of the protrusion 5, and the clamping plate 14 is provided with the rubber sealing pad 6 made of the same material as that of the protrusion 5. The protrusion 5 and the clamping plate 14 are provided in two groups and are respectively arranged on the four sides of the base plate 1. The protrusion 5 can be inserted between the clamping plates 14 to facilitate the connection of adjacent base plates 1, and the rubber sealing pad 6 can improve the sealing of the connection between adjacent base plates 1, thereby preventing concrete from penetrating downward.

[0027] Specifically, a screw hole 15 is provided inside the base plate 1, and a connecting screw 16 is connected inside the screw hole 15. The upper part of the connecting screw 16 is connected to the inside of the V-shaped steel bar 3. A screw hole 2 17 matching the connecting screw 16 is provided inside the V-shaped steel bar 3. The depth of the screw hole 2 17 is the same as the length of the connecting screw 16. A cross groove is provided at the bottom of the connecting screw 16. The connecting screw 16 can be rotatably connected inside the screw hole 2 17. After the connecting screw 16 is screwed into the screw hole 2 17, not only can the base plate 1 be separated from the V-shaped steel bar 3, but also the bottom of the poured concrete can be kept flat, reducing the problem of holes left after the concrete is poured, and saving the cost of use.

[0028] Example 2: Please refer to Figure 2The difference between this embodiment and embodiment 1 is that: the positioning rod 8 is slidably connected inside the positioning seat 1 7, and one end of the positioning rod 8 is conical, and a positioning seat 2 18 is provided below the bottom plate 1 on the opposite side of the positioning seat 1 7. The shape and size of the positioning seat 2 18 are the same as those of the positioning seat 1 7, and a through hole is provided inside the positioning seat 2 18 to accommodate the positioning rod 8, the slider 10 is embedded in the push plate 9, and the slider 10 is slidably connected inside the push plate 9.

When the crank 11 is rotated, the positioning rod 8 can be driven to move and be inserted into the positioning seat 2 18, so that adjacent bottom plates 1 can be aligned and connected with each other to prevent the bottom plates 1 from offsetting or tilting.

[0029] The working principle of the utility model is as follows: when in use, the adjacent base plates 1 are aligned, and then the handle 13 is rotated. The handle 13 drives the crank 11 to rotate, so that the crank 11 pushes the push plate 9 and the positioning rod 8 to move, so that the positioning rod 8 is inserted into the positioning seat 18 on the base plate 1 on the adjacent side, and then the base plate 1 on one side is pushed, and the protrusion 5 on the base plate 1 is clamped in the clamping plate on the base plate 1 on the other side. After pouring concrete above the floor decking, the connecting screw 16 can be tightened inside the V-shaped steel bar 3 to disengage the connecting bolt 16 from the inside of the base plate 1. Not only can the connecting screw 16 be removed from the base plate 1, reducing the problem of holes left after concrete pouring, but also the use cost can be saved.
