Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a connection structure between a PC floor slab and a cast-in-place slab strip. Background Technology

[0002] With the continuous growth of the world's population and the acceleration of urbanization, traditional construction methods face significant challenges in meeting housing demands. Therefore, prefabricated construction is considered a key area for future sustainable development. Currently, prefabricated construction in China has been applied in various fields, including residential construction, public facilities, and commercial offices. For example, prefabricated construction is widely used in relocation projects for poverty alleviation, significantly shortening construction cycles and improving overall quality. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a connection structure between PC floor slabs and cast-in-place slab strips, which facilitates the control of concrete forming quality at the interface and reduces the impact caused by construction inconvenience.

[0004] The present invention adopts the following technical solution:

[0005] A connection structure between a PC floor slab and a cast-in-place slab strip includes a connecting rod, a threaded rod, a template, timber, and a nut. The connecting rod is horizontally positioned, and its middle position is connected to the top of the threaded rod. The bottom of the threaded rod passes through the slab strip, and the timber rests on the bottom of the template of the slab strip. The nut is fixed to the lower end of the threaded rod and is located at the bottom of the timber.

[0006] Furthermore, foam strips are pre-applied to the completed template around the perimeter of each PC floor slab.

[0007] Furthermore, the top of the connecting rod and the screw are connected by welding.

[0008] Furthermore, at the very center of the strip, a hole is set every 1 meter, one end of the screw is inserted into the hole, and the two ends of the connecting rod abut against the PC floor slabs on both sides.

[0009] Furthermore, after the nut is fixed to the lower end of the screw, steel bars are tied to the upper part of the PC floor slab and strip.

[0010] Furthermore, the connecting rod has a diameter of 16mm and a length of 300mm, and the screw is model M12×200.

[0011] Furthermore, the screw is set vertically.

[0012] Beneficial effects

[0013] This invention can reduce issues such as concrete leakage and cracking in the later stages, improving the appearance quality of the concrete. Utilizing surplus waste materials such as steel bars, bolts, and timber on-site avoids resource waste, improves the quality of concrete pouring, achieves technological efficiency, and saves construction costs.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] As shown in the figure, this utility model discloses a connection structure between a PC floor slab and a cast-in-place slab strip, including a connecting rod 3, a screw rod 4, a template 6, a timber 7, and a nut 8. The connecting rod 3 is horizontally arranged, and the middle position of the connecting rod 3 is connected to the top of the screw rod 4. The lower end of the screw rod 4 is set on the slab strip 2. The timber 7 is placed on the bottom of the template 6 of the slab strip 2. The nut 8 is fixed to the lower end of the screw rod 4 and is located at the bottom of the timber 7.

[0018] Nut 8 is used to fix screw 4.

[0019] After installation, pour concrete. Once the concrete reaches the required strength, remove the bottom timber 7 and formwork 6, and cut off the excess portion at the bottom of the screw rod 4.

[0020] The connecting rod 3 here can be made from scrap steel bars or scrap screws.

[0021] In one embodiment of this utility model, before installing the PC floor slab 1, control lines for the installation of the PC floor slab 1 are laid out, and sponge adhesive strips are pre-attached to the completed template 6 around the perimeter of each PC floor slab 1. The PC floor slabs are then installed according to the control lines.

[0022] In one embodiment of this utility model, the top of the connecting rod 3 and the screw 4 are connected by welding.

[0023] In one embodiment of this utility model, a hole is set every 1 meter in the middle of the strip 2, and one end of the screw 4 is inserted into the hole, and the two ends of the connecting rod 3 abut against the PC floor slabs 1 on both sides.

[0024] In one embodiment of this utility model, after the nut 8 is fixed to the lower end of the screw 4, reinforcing bars are tied to the upper part of the PC floor slab 1 and the strip 2. After the reinforcing bars are tied, concrete can be poured.

[0025] In one embodiment of this utility model, the diameter of the connecting rod 3 is 16mm and the length is 300mm, and the screw 4 is of model M12×200.

[0026] In one embodiment of this utility model, the screw 4 is vertically arranged.

[0027] This invention can reduce issues such as concrete leakage and cracking in the later stages, improving the appearance quality of the concrete. Utilizing surplus waste materials such as steel bars, bolts, and timber on-site avoids resource waste, improves the quality of concrete pouring, achieves technological efficiency, and saves construction costs.

[0028] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
