Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a post-cast strip of basement floor slab with a PVC pipe hole support structure. Background Technique

[0002] During the construction of the basement floor slab, it is necessary to install precast unit beams on the top of concrete independent columns, and then carry out post-cast strip construction between two adjacent precast unit beams to form an integral top beam. However, there are still some defects in the existing post-cast strips of basement floor slabs during use;

[0003] For example, a post-cast strip PVC pipe formwork concrete independent column support system proposed in the application number CN202322965324.6 includes a PVC pipe formwork and a support frame. The support frame stands on the ground and is used to support the PVC pipe formwork. The support frame is wound and fixed to the concrete independent column. The set concrete independent column in this application can support and reinforce the support frame, making the stability of the support frame better during installation and use. Furthermore, the support effect of the support frame on the PVC pipe formwork is better, improving the stability of the PVC pipe formwork during concrete pouring. In the actual use process, a support frame needs to be erected to support the post-cast strip formwork before pouring, and a secondary erection of a back-topping frame is required after the formwork support is removed. The measures are complex and the full hall frame affects the transportation and passage of basement materials, restricting the overall construction period and reducing the use effect and the use strength of the post-cast strip.

[0004] Therefore, we propose a post-cast strip of basement floor slab with a PVC pipe hole support structure to solve the problems mentioned above. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-5 , the present invention provides a technical solution: a basement floor post-cast strip with a PVC pipe hole support structure, including a post-cast strip body 1, a PVC pipe formwork 2 is installed through the inside of the post-cast strip body 1, the bottom outer ring of the PVC pipe formwork 2 is fixedly sleeved with a floor slab 3, a structure strengthening mechanism 4 is installed inside the post-cast strip body 1 and the PVC pipe formwork 2, the structure strengthening mechanism 4 includes longitudinal strengthening ribs 401 evenly distributed inside the post-cast strip body 1, transverse strengthening ribs 402 are symmetrically distributed inside the post-cast strip body 1, support ribs 403 are equally angled inside the PVC pipe formwork 2, connecting ring ribs 404 are evenly installed on the outer ring of the support ribs 403, the top of the support ribs 403 is in contact with the longitudinal strengthening ribs 401 and the transverse strengthening ribs 402, and the joints between the longitudinal strengthening ribs 401, the transverse strengthening ribs 402, the support ribs 403 and the connecting ring ribs 404 are fixedly connected by steel wires;

[0029] The design of the above structure enables the longitudinal strengthening ribs 401 and the transverse strengthening ribs 402 to improve the structural strength of the post-cast strip body 1, while the support ribs 403 and the connecting ring ribs 404 can improve the structural strength of the concrete poured inside the PVC pipe formwork 2, improving the structural stability of the basement floor post-cast strip with a PVC pipe hole support structure.

[0030] The bottom of the post-cast strip body 1 is attached with a first template 5 and a second template 6. The first template 5 and the second template 6 are connected to each other through a sealing connection mechanism 7. The sealing connection mechanism 7 includes a docking groove 701 opened inside the first template 5. A docking strip 702 is fixedly installed on the inner side of the second template 6. The size of the docking groove 701 matches the size of the docking strip 702. The bottom surface of the first template 5 is symmetrically installed with connecting plates 703. A clamping groove 704 is opened inside the connecting plates 703. The bottom surface of the second template 6 is symmetrically installed with limit seats 705. A clamping rod 706 is slidably penetrated through the limit seats 705. A spring 707 is sleeved outside the clamping rod 706. The two ends of the spring 707 are fixedly connected to the clamping rod 706 and the limit seats 705 respectively. The clamping rod 706 and the limit seats 705 form a telescopic structure through the spring 707. The clamping rod 706 is snap-fitted with the clamping groove 704;

[0031] The design of the above structure enables the first template 5 to be hermetically connected to the docking strip 702 on the second template 6 through the docking groove 701 when installing the first template 5 and the second template 6. At the same time, when docking the first template 5 and the second template 6, the connecting plate 703 will also be inserted into the limit seat 705.
