Description

Technical Field

[0001] The utility model belongs to the technical field of post-cast strip construction, and particularly relates to an independent support system for a post-cast strip. Background Art

[0002] Traditional post-cast strip construction uses a steel pipe support frame system. The post-cast strip support frame needs to be disconnected from the full-floor frame and retained until the post-cast strip is closed and concrete curing is completed.

[0003] Later, a post-cast strip support system using PVC tube formwork and independent concrete columns emerged. For example, the Chinese utility model patent document with authorization announcement number CN221799145U discloses a beam-slab support structure at the post-cast strip. The structure uses PVC tubes, which are installed simultaneously with the formwork. The concrete inside the tubes and the beam and slab are poured into the structure at the same time. After the full-floor support is removed, the post-cast strip independent column support system is naturally formed. This system can also improve the turnover rate of the formwork and support, reducing costs. However, this support system also has its shortcomings. For example, the bottom of the tube formwork directly contacts the ground, resulting in poor stability. In addition, the length of the tube formwork needs to be precisely cut according to the support length. If the tube formwork is too long, it will affect its installation, while if it is too short, it will affect the support effect.

[0004] Therefore, it is necessary to design an independent support system for the post-casting strip that improves stability, adjusts height, reduces the requirements for the accuracy of the pipe mold length, and improves construction convenience to solve the current technical problems. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides an independent support system for a post-casting strip that improves stability, is height-adjustable, reduces requirements for pipe mold length accuracy, and improves construction convenience.

[0006] The technical solution of the present invention is: an independent support system for the post-cast strip, including a beam slab, a support tube is provided at the bottom of the beam slab, a support base is provided at the bottom end of the support tube, the support base has a bottom tube, a support plate which is an integral structure thereof is fixedly provided at the bottom of the bottom tube, at least three support plates are provided in a circular array on the outside of the support plate, a bottom foot is provided below the support plate for sliding in the vertical direction, and an adjusting bolt which is threadedly connected to the support plate is provided on the top of the base foot for vertical rotation.

[0007] A guide rod parallel to the axis of the adjusting bolt is fixedly provided on the top of the base, the guide rod is slidably connected to the support plate, and a limit plate is fixedly provided on the top end of the guide rod.

[0008] A rubber inner tube is fixedly provided inside the bottom tube, and the support tube is detachably interference-inserted inside the rubber inner tube.

[0009] A plastic film is sheathed on a position of the lower end of the support tube corresponding to the rubber inner tube.

[0010] The base foot is a waist-shaped plate structure, and a rubber pad matching its shape is fixedly provided on the bottom of the base foot. Fixing holes are correspondingly provided on the base foot and the rubber pad.

[0011] The outer side thread of the adjusting bolt above the support plate is assembled with a locking nut.

[0012] The supporting tube is a PVC tube.

[0013] The diameter of the support tube is not less than 150 mm.

[0014] The support pipe is a DN200 PVC pipe, and the wall thickness of the support pipe is 4.0 mm.

[0015] The outer side of the supporting plate is provided with four supporting plates in a circular array.

[0016] Beneficial effects of the utility model:

[0017] (1) In the present invention, the bottom end of the support tube is assembled inside the bottom tube, and the bottom tube is supported by a support plate below the bottom tube. The bottom frame below the support plate around the support plate is in contact with the ground, thereby increasing the support area and improving the stability of the bottom end of the support tube;

[0018] (2) By rotating the adjusting bolt, the distance between the base and the support plate can be adjusted, thereby adjusting the support height of the support frame to the support pipe. The length error of the support pipe mold can be compensated by adjusting the support height of the support frame to the support pipe, thereby reducing the requirement for the length accuracy of the pipe mold and improving the convenience of construction.

[0025] like Figures 1 to 3 As shown, the post-casting strip independent support system includes a beam slab 2, a support pipe 3 is provided at the bottom of the beam slab 2, a support base 1 is provided at the bottom end of the support pipe 3, and the support base 1 has a bottom pipe 11. The bottom of the bottom pipe 11 is fixedly provided with a support plate 12 as an integral structure therewith, and the outer side of the support plate 12 is provided with at least three support plates 13 in a circumferential array. A foot 14 is provided below the support plate 13 for sliding in the vertical direction, and an adjusting bolt 15 connected to the support plate thread 13 is provided at the top of the foot 14 for vertical rotation. In this embodiment, the bottom end of the support pipe 3 is assembled inside the bottom pipe 11, and is supported below the bottom pipe 11 by the support plate 12. The base frame 14 below the support plates 13 around the support plate 12 is in contact with the ground, increasing the support area and improving the stability of the bottom end of the support pipe 3; rotating the adjusting bolt 15 can adjust the distance between the base foot 14 and the support plate 13, thereby adjusting the support height of the support base frame 1 to the support pipe 3, and the length error of the pipe mold of the support pipe 3 can be compensated by adjusting the support height of the support base frame 1 to the support pipe 3, reducing the requirements for the length accuracy of the pipe mold and improving the convenience of construction; the heights of multiple base feet can be adjusted separately, and they can be adjusted separately when the ground is uneven, providing stable support for the support pipe 3.

[0026] In some embodiments, a guide rod 16 parallel to the axis of the adjusting bolt 15 is fixedly provided on the top of the base foot 14, and the guide rod 16 is slidably connected to the support plate 13. A limit plate 17 is fixedly provided on the top of the guide rod 16. The limit plate 17 can prevent the guide rod 16 from slipping off the support plate 13. The base foot 14 cooperates with the support plate 13 through the guide rod 16 to achieve a sliding connection between it and the support plate 13 in the vertical direction.

[0027] In some embodiments, a rubber inner tube 111 is fixedly installed inside the bottom tube 11, and the support tube 3 is detachably inserted into the rubber inner tube 111. The rubber inner tube 111 generates elastic deformation to apply elastic force to the outside of the support tube 3, making it difficult to detach from the bottom tube 11.

[0028] In some embodiments, a plastic film is provided at the position corresponding to the lower end of the support tube 1 and the rubber inner tube 111. The plastic film can isolate the concrete from the bottom tube 11 and the support plate 12 after pouring, making it easy to remove the support rod 3 from the bottom tube 11 after cutting and removing the support tube 3, which is conducive to the rapid turnover of the support frame 1.

[0029] In some embodiments, the base 14 is a waist-shaped plate structure, and a rubber pad 18 matching its shape is fixed to the bottom of the base 14. The rubber pad 18 can increase the friction between the base 14 and the ground and improve stability. Corresponding fixing holes 19 are opened on the base 14 and the rubber pad 18. During installation, expansion bolts corresponding to the fixing holes 19 can be set on the ground. The base 14 is fixed to the ground by the expansion bolts, which can further improve the stability of the connection between the base 14 and the ground.

[0030] In some embodiments, the outer side of the adjusting bolt 15 above the support plate 13 is threadedly equipped with a locking nut 151. After the distance between the base 14 and the support plate 13 is adjusted by the adjusting bolt 15, the locking nut 151 can be tightened so that it is against the top of the support plate 13, locking the adjusting bolt 15 and the support plate 13 to prevent loosening.

[0031] In some embodiments, the support tube 3 is a PVC tube, which has high strength and small weight, and is convenient for cutting and use; specifically, the diameter of the support tube 3 is not less than 150 mm; more specifically, the support tube 3 is a DN200 PVC tube, and the wall thickness of the support tube is 4.0 mm.

[0032] In some embodiments, four support plates 13 are arranged in a circumferential array on the outer side of the support plate 12 .
