Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a high-strength PVC pipe mold concrete independent column. Background Technique

[0002] The traditional steel pipe support system needs to set up a full hall scaffold, and at the same time, it is necessary to set up a secondary back support scaffold after the formwork support is removed. The measures are complex and the full hall scaffold affects the transportation and passage of basement materials;

[0003] Embedded channel steel back support can avoid the disadvantages of the traditional steel pipe full hall scaffold support system, but the rental cost of channel steel increases the cost greatly. By using a PVC pipe mold concrete independent column, it is installed synchronously with the formwork, and the concrete in the pipe and the beam and slab are poured integrally at one time. After the full hall formwork support is removed, an independent column support system is naturally formed. However, there are still certain defects in the existing PVC pipe mold concrete independent columns during use;

[0004] For example, a UPVC pipe concrete column support system for the post-cast strip of the basement floor slab proposed in the application number CN202222736632.7 belongs to the technical field of building engineering construction, including a plurality of UPVC pipe concrete column structures fixed on both sides of the post-cast strip. Each of the UPVC pipe concrete column structures includes: a base, a top support and a UPVC pipe mold; the base is fixed on the basement floor slab, and an installation hole is opened on the base; the top support is fixed on the basement floor slab and a positioning hole is opened on it; the UPVC pipe mold is arranged vertically, its upper end is sleeved in the positioning hole, and its lower end is sleeved in the installation hole; the UPVC pipe mold includes two UPVC pipe half molds, the two UPVC pipe half molds are symmetrically arranged and detachably connected. In the actual use process, the UPVC pipe half molds in this application are arranged in multiple sections and are spliced during use. The multi-section setting will reduce the integration effect and the use strength, and at the same time, the multi-section UPVC pipe half molds are not convenient for storage and transportation, and it is easy to produce a scattered phenomenon during transportation and storage.

[0005] Therefore, we propose a high-strength PVC pipe mold concrete independent column to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a high-strength PVC pipe mold concrete independent column to solve the problems that the multi-section design in the above background technology is easy to reduce the use strength and the transportation and storage effect.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A high-strength PVC pipe mold concrete independent column, including a lower independent column and an upper independent column,

[0008] Reinforcing plates are fixedly installed on the outer circles of the lower independent column and the upper independent column, and a splicing and positioning mechanism is used for sealed connection between the top end of the lower independent column and the bottom end of the upper independent column;

[0009] The bottom end of the lower independent column is fixedly installed with a bottom plate;

[0010] A telescopic sealing mechanism is installed at the top of the upper independent column. The top end of the upper independent column is sleeved with a cast-in-place beam slab, and a groove is opened at the bottom of the cast-in-place beam slab.

[0011] Preferably, the splicing and positioning mechanism includes sealing grooves on the outer circles of the top end of the lower independent column and the bottom end of the upper independent column. A first clamping ring and a second clamping ring are attached to the outer circle at the connection of the lower independent column and the upper independent column. Sealing rings are symmetrically installed on the inner circles of the first clamping ring and the second clamping ring, and the sealing rings are closely attached to the sealing grooves.

[0012] Preferably, clamping seats are fixedly installed on the outer circles at both ends of the second clamping ring. Clamping grooves are opened inside the clamping seats. Fixed seats are fixedly installed on the outer circles at both ends of the second clamping ring. Fixing plates are fixedly installed on the inner sides of the fixed seats.

A clamping block is fixedly installed at one end of the connecting seat, and the clamping block is movably clamped and connected with the clamping groove.

[0013] Preferably, telescopic rods are symmetrically connected between the connecting seat and the fixing plate, and the adjusting screw rod and the connecting seat form a threaded telescopic structure.

[0014] With the design of the above structure, it is convenient for the reinforcing plates to effectively improve the structural strength of the lower independent column and the upper independent column. The setting of the splicing and positioning mechanism can facilitate the convenient splicing between the lower independent column and the upper independent column, which is beneficial to selecting a suitable upper independent column and lower independent column for splicing according to the height of the cast-in-place beam slab to achieve support work at various heights. At the same time, the two-section design of the lower independent column and the upper independent column is also convenient for transportation and storage.

[0015] Preferably, the telescopic sealing mechanism includes a positioning plate fixedly installed on the outer circle of the top of the upper independent column. A lifting rod penetrates through the positioning plate. The top end of the lifting rod is fixedly connected with a top plate. A spring is sleeved on the outer circle of the lifting rod between the top plate and the positioning plate. A sealing pad is fixedly installed on the top surface of the top plate.

[0016] Preferably, the lifting rod and the spring are equally angularly distributed between the positioning plate and the top plate, and the spring pushes the sealing pad to closely fit with the groove.

[0017] With the design of the above structure, when connecting the upper independent column to the cast beam and slab, the expansion and sealing mechanism can closely fit with the groove, facilitating the sealing of the connection between the upper independent column and the cast beam and slab, avoiding leakage and improving the sealing effect.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. 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 efforts 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 high-strength PVC pipe mold concrete independent column, including a lower independent column 1 and an upper independent column 2. The outer circles of the lower independent column 1 and the upper independent column 2 are fixedly installed with a reinforcement plate 3. The top end of the lower independent column 1 and the bottom end of the upper independent column 2 are hermetically connected by a splicing positioning mechanism 4. The splicing positioning mechanism 4 includes a sealing groove 401 on the outer circle of the top end of the lower independent column 1 and the outer circle of the bottom end of the upper independent column 2. The outer circles of the connection part of the lower independent column 1 and the upper independent column 2 are fitted with a first clamping ring 402 and a second clamping ring 403. The inner circles of the first clamping ring 402 and the second clamping ring 403 are symmetrically installed with a sealing ring 404, and the sealing ring 404 is closely fitted with the sealing groove 401;

[0029] The outer circles of both ends of the second clamping ring 403 are fixedly installed with clamping seats 405. The inside of the clamping seat 405 is provided with a clamping groove 406. The outer circles of both ends of the second clamping ring 403 are fixedly installed with fixed seats 407. The inner sides of the fixed seats 407 are fixedly installed with fixed plates 408. One side of the fixed plate 408 is rotatably installed with an adjusting screw 409. One end of the adjusting screw 409 is sleeved with a connecting seat 410. Telescopic rods 411 are symmetrically connected between the connecting seat 410 and the fixed plate 408. The adjusting screw 409 and the connecting seat 410 form a threaded telescopic structure. One end of the connecting seat 410 is fixedly installed with a clamping block 412, and the clamping block 412 is movably clamped and connected with the clamping groove 406;

[0030] The design of the above structure enables the setting of the reinforcement plate 3 to enhance the individual structural strength of the lower independent column 1 and the upper independent column 2. When splicing the lower independent column 1 and the upper independent column 2, first, the upper independent column 2 with a corresponding length needs to be adapted according to the height of the cast beam and slab 7. Then, the bottom end of the upper independent column 2 is fitted to the bottom end of the lower independent column 1. Furthermore, after aligning the sealing rings 404 inside the first clamping ring 402 and the second clamping ring 403 with the sealing grooves 401 opened at the top end of the lower independent column 1 and the bottom end of the upper independent column 2, the first clamping ring 402 and the second clamping ring 403 are sleeved on the connection part of the lower independent column 1 and the upper independent column 2. Then, by rotating the adjusting screw rod 409, the connection seat 410 and the clamping block 412 can be driven to move, so as to facilitate the clamping block 412 to engage with the clamping groove 406 opened in the clamping seat 405, thus completing the fixed connection of the first clamping ring 402 and the second clamping ring 403 and realizing the splicing and positioning of the lower independent column 1 and the upper independent column 2;

[0031] The setting of the telescopic rod 411 can ensure the stability of the movement of the connection seat 410 and the clamping block 412 during the clamping process with the clamping groove 406.

[0032] The bottom end of the lower independent column 1 is fixedly installed with a bottom plate 5, the top of the upper independent column 2 is installed with a telescopic sealing mechanism 6, the top end of the upper independent column 2 is sleeved with a cast beam and slab 7, and a groove 8 is opened at the bottom of the cast beam and slab 7. The telescopic sealing mechanism 6 includes a positioning plate 601 fixedly installed on the outer circle of the top of the upper independent column 2. A lifting rod 602 penetrates through the inside of the positioning plate 601. The top end of the lifting rod 602 is fixedly connected with a top plate 603. A spring 604 is sleeved outside the lifting rod 602 between the top plate 603 and the positioning plate 601. The lifting rod 602 and the spring 604 are equally angularly distributed between the positioning plate 601 and the top plate 603. A sealing gasket 605 is fixedly installed on the top surface of the top plate 603. The spring 604 pushes the sealing gasket 605 to closely fit with the groove 8;

[0033] The design of the above structure enables the spring 604 to push the top plate 603 to rise when connecting the top end of the upper independent column 2 with the cast beam and slab 7, and drive the sealing gasket 605 to closely fit with the groove 8 at the bottom of the cast beam and slab 7 to form a seal, thus being able to avoid leakage from the connection part during the subsequent concrete pouring and improving the sealing effect. The equally spaced distribution of the lifting rods 602 and their sliding connection with the positioning plate 601 can effectively limit the expansion and contraction of the top plate 603 and improve the stability.

[0034] Thus, a series of work is completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
