Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an independent column back-support structure of PVC pipe formwork for heavy vehicle routes. Background Technique

[0002] During the construction of the garage, it is usually necessary to back-support the heavy vehicle lanes on the top slab of the garage. The traditional steel pipe support system requires the erection of a full hall formwork, and at the same time, it is necessary to erect a secondary back-support frame after the formwork support is removed. The measures are complex and the full hall formwork affects the material transportation and passage in the basement, affects the early penetration of the mechanical and electrical pipelines in the basement, and restricts the overall construction period.

[0003] The embedded channel steel back-support can avoid the disadvantages of the traditional steel pipe full hall formwork support system, but the rental cost of the channel steel increases and the cost is relatively large. Therefore, the independent column back-support structure of PVC pipe formwork can not only avoid the disadvantages of the full hall formwork but also reduce the cost of the embedded channel steel back-support. However, there are still certain defects in the existing independent column back-support structure of PVC pipe formwork during use.

[0004] For example, a post-cast strip PVC pipe plain concrete support system proposed in the application number 202120338813.7, which relates to the technical field of building construction engineering. The outside of the structural beam is provided with structural beam stirrups, and the structural beam is fixedly connected with the structural beam stirrups. The first PVC pipe support is installed below the structural beam, and the structural beam is fixedly connected with the first PVC pipe support. The first PVC pipe formwork is installed below the first PVC pipe support, and the first PVC pipe support is fixedly connected with the first PVC pipe formwork. The first PVC pipe formwork penetrates through the first PVC pipe support. The bottom reinforcement of the structural slab is arranged below the top slab formwork. The second PVC pipe support is installed below the top slab formwork, and the top slab formwork is fixedly connected with the second PVC pipe support. During actual use, the bottom of this application is supported by a reinforced plywood assembly, but such a support structure is prone to tilt, thus reducing the stability during the subsequent pouring process. At the same time, there is no sealing structure between the top end and the top slab in this application, and thus leakage will occur from the connection during the subsequent pouring process, reducing the use effect.

[0005] Therefore, we propose an independent column back-support structure of PVC pipe formwork for heavy vehicle routes to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide an independent column back-support structure of PVC pipe formwork for heavy vehicle routes to solve the problems of easy tilt causing reduced stability and reduced top sealing and easy leakage raised in the above background technique.

At the same time, the inclination angle of the auxiliary support mechanism can be adjusted, which is beneficial to adjusting the support occupation range of the auxiliary support mechanism according to the needs of the indoor use space, and improving the practicability of the auxiliary support mechanism.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , the present invention provides a technical solution: a jacking structure for the independent column of the PVC pipe mold on the heavy vehicle route, including a PVC pipe mold body 1, a bottom sealing ring 2 is fixedly installed at the bottom of the PVC pipe mold body 1, positioning rings 3 are symmetrically sleeved on the outer ring of the bottom of the PVC pipe mold body 1, a hoop 4 is installed on the surface of the PVC pipe mold body 1 between the positioning rings 3, and auxiliary support mechanisms 5 are installed at equal angles inside the hoop 4. The auxiliary support mechanism 5 includes connecting seats 501 installed at equal angles inside the hoop 4, a rotating shaft 502 is rotatably installed inside the connecting seat 501, an upper support plate 503 is fixedly sleeved on the outer ring of the rotating shaft 502, the upper support plate 503 is rotationally connected to the connecting seat 501 through the rotating shaft 502, a connecting shaft 504 is connected to the bottom end of the upper support plate 503, a turning handle 505 is connected to the bottom end of the connecting shaft 504, a threaded rod 506 is installed at the bottom end of the turning handle 505, the turning handle 505 and the threaded rod 506 are rotationally connected to the upper support plate 503 through the connecting shaft 504, a lower support plate 507 is sleeved on the outer ring of the threaded rod 506, the threaded rod 506 is threadedly connected to the lower support plate 507, and a mounting plate 508 is rotatably installed at the bottom end of the lower support plate 507;

[0028] The design of the above structure enables the bottom end of the PVC pipe mold body 1 to closely fit the ground in cooperation with the bottom sealing ring 2 during the installation of the PVC pipe mold body 1, preventing leakage. By rotating the upper support plate 503, it can rotate and adjust the angle inside the connecting seat 501 in cooperation with the rotating shaft 502, which is beneficial to adjusting the inclination angle and the supporting occupied area of the upper support plate 503 and the lower support plate 507 according to the indoor site use requirements. After the inclination angle adjustment is completed, by rotating the turning handle 505, the turning handle 505 can rotate at the bottom end of the connecting shaft 504 and drive the threaded rod 506 to rotate. At this time, manually limit the lower support plate 507, so that the rotation of the threaded rod 506 can drive the lower support plate 507 to move in position until the mounting plate 508 at the bottom end of the lower support plate 507 can fit the ground. At this time, the mounting plate 508 and the ground are fixedly connected by expansion bolts to realize the positioning of the auxiliary support mechanism 5 and the support of the PVC pipe mold body 1;

[0029] After the PVC pipe mold body 1 is poured, the hoop 4 can be disassembled to separate it from the positioning ring 3, and then the hoop 4 and the auxiliary support mechanism 5 can be disassembled to realize recycling.

[0031] The design of the above structure enables the top of the PVC pipe mold body 1 to be docked with the heavy vehicle line top mold 7 after the bottom of the PVC pipe mold body 1 is installed. Then, by rotating the threaded socket 602, it spirally rises on the external thread 601 on the outer circle of the top of the PVC pipe mold body 1, and then drives the top plate 604 to rise in cooperation with the fixed shaft 603. Then, the top plate 604 will drive the top sealing ring 605 to be in a mating connection with the sealing groove 606 at the bottom of the heavy vehicle line top mold 7, so as to seal the connection between the top of the PVC pipe mold body 1 and the heavy vehicle line top mold 7, avoiding leakage from the connection during the subsequent pouring process and further improving the sealing effect.
