Description

Technical Field

[0001] This utility model relates to the field of composite plate reinforcement technology, specifically a composite plate strip reinforcement structure. Background Technology

[0002] With the development of industrialized construction, precast concrete composite slabs are increasingly widely used in construction projects. During construction, after multiple composite slabs are placed and installed, concrete needs to be poured on the composite slabs and the strips between them. Before pouring, plywood boards need to be fixed to the bottom of the strips to prevent concrete from leaking through the gaps between the composite slabs during the pouring process. After the concrete has solidified, the plywood boards need to be removed. In the existing technology, the fasteners used to fix the plywood boards are partially or completely poured into the concrete, and some protruding parts of the fasteners sometimes need to be cut off. The process is cumbersome and costly. Therefore, this utility model proposes a composite slab strip reinforcement structure. Summary of the Invention

[0003] The purpose of this utility model is to propose a composite plate and strip reinforcement structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a composite slab strip reinforcement structure, including a top rod, a lead screw fixedly connected to the bottom of the middle end of the top rod, the lead screw having threads on its outer side and a fastening nut screwed in, the top rod being positioned above the gap between two composite slabs, the lead screw passing through a plywood positioned below the gap between the two composite slabs and slidably connected to the plywood, cement pads being positioned between the bottom of both ends of the top rod and the top of the composite slab, and a sleeve being fitted around the outside of the lead screw, the sleeve being slidably connected to the lead screw.

[0005] Preferably, one end of the lead screw passes through a short wooden board, and wooden pads are provided on the side of the short wooden board near the plywood at both ends.

[0006] Preferably, a slidable ingot pad is provided on the lead screw, and the ingot pad is disposed between the fastening nut and the short wooden board.

[0007] Compared with the prior art, the beneficial effects of this utility model are: by setting a cement block between the composite plate and the top rod, the top rod is made higher than the concrete pouring surface, and a sleeve is fitted on the threaded rod to separate the threaded rod from the concrete, which makes it convenient to remove the threaded rod and the top rod after pouring, and reuse them to save costs and reduce the process of cutting the protruding parts.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Referring to Figure (1), a composite board strip reinforcement structure includes a top rod 1. A lead screw 3 is fixedly connected to the bottom of the middle end of the top rod 1. The lead screw 3 has threads on its outer side and is screwed with a fastening nut 4. The top rod 1 is positioned above the gap between two composite boards 5. The lead screw 3 passes through a plywood board 6 positioned below the gap between the two composite boards and is slidably connected to the plywood board 6. Cement pads 8 are provided between the bottom of both ends of the top rod 1 and the top of the composite board 5. A sleeve 2 is fitted on the outer side of the lead screw 3, and the sleeve 2 is slidably connected to the lead screw 3. One end of the lead screw 4 passes through a short wooden board 7. Wooden pads 9 are provided on the side of both ends of the short wooden board 7 near the plywood board 6. A slidable ingot pad is provided on the lead screw 3, and the ingot pad is positioned between the fastening nut 4 and the short wooden board 7.

[0012] When using this device, the cement block 8 can be prefabricated to a suitable height according to the height of the concrete to be poured, and a sleeve 2 of corresponding height can be made. The sleeve can be made of PVC material. Holes for the threaded rod to pass through are pre-drilled in the plywood 6 and short wooden boards 7. During construction, after the composite slab is placed and installed, the plywood 6 is placed below the gap between the composite slabs to block the gap. The threaded rod 3 is then fitted onto the sleeve 2 and passed through the plywood 6 and short wooden boards 7. The cement block 8 is placed between the top of the composite slab 5 and the top rod 1, and the wooden block 9 is placed... Between the short wooden board 7 and the plywood 6, tighten the fastening nut 4 to secure them, ensuring a tight fit between the plywood 6 and the composite board 5. After the concrete is poured and solidified, the cement block 8 and the sleeve 2 remain inside the poured concrete. Loosen the fastening nut 4 and remove the top rod 1 and the threaded rod 3. The plywood 6, short wooden board 7, and wooden block 9 can also be removed and reused after losing their support. The holes left on the sleeve 2 can be filled with dry-hardened cement mortar. The cement blocks and sleeves consumed in the above construction can be made from low-cost materials, reducing costs.
