Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete formwork reinforcement technology, specifically a concrete formwork reinforcement device for building construction. Background Technology
[0002] Concrete formwork reinforcement devices are key facilities in building construction to ensure the stability of formwork and guarantee the quality of concrete pouring. Through reasonable mechanical structural design, they tightly connect the formwork, support system and building structure, effectively resisting the lateral pressure, gravity and vibration impact generated during concrete pouring.
[0003] Concrete formwork is generally assembled by means of threaded connection, snap-fit splicing or welding, which can prevent construction defects such as concrete bulging and displacement. When reinforcing the beams of a building ceiling, the formwork needs to be attached to the outer surface of the beam and then the formwork is limited and fixed by connecting rods. A vertical support frame is then used to support the bottom of the formwork to reinforce and fix the beam concrete.
[0004] When the vertical support frame is integrated with the formwork reinforcement device, it exerts an upward force on the bottom of the formwork, causing deformation and potentially leading to concrete leakage. Furthermore, uneven ground can cause instability in the support frame, resulting in its collapse and compromising the formwork's stability. Therefore, this paper proposes a concrete formwork reinforcement device for building construction to address these issues. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-5 As shown, a concrete formwork reinforcement device for building construction includes a base 1, a support rod 11 fixedly installed on the top of the base 1, a lifting component 2 provided on the top of the support rod 11, a reinforcement component 3 installed on the top of the lifting component 2, and an adjustment component 4 provided inside the base 1.
[0026] The reinforcement component 3 includes a support plate 301. Fixing plates 302 are fixedly installed on the top left and right sides of the support plate 301. A threaded hole is opened on the left side of the fixing plate 302. A threaded rod 303 is threadedly connected inside the threaded hole. A stop plate 304 is rotatably connected to the right side of the threaded rod 303. A sliding groove 305 is opened on the top of the support plate 301. A slider 306 is slidably installed inside the sliding groove 305. A connecting block 307 is fixedly installed at the bottom of the slider 306. A sliding rod 308 is fixedly installed on the left side of the stop plate 304. A compression spring 309 is sleeved on the outer surface of the sliding rod 308.
[0027] The left side of the slide bar 308 extends through to the left side of the fixed plate 302, the right side of the compression spring 309 is installed on the outside of the abutment plate 304, and the slider 306 is fixedly installed on the bottom of the abutment plate 304.
[0028] There are two abutment plates 304, which are symmetrically distributed on the top of the support plate 301.
[0029] Through the above technical solution, the fixing plate 302 is fixedly installed on the top side of the support plate 301, so that the threaded rod 303 can rotate in the threaded hole opened inside the fixing plate 302. Rotating the threaded rod 303 causes the abutment plate 304, which is rotatably connected to the right side of the threaded rod 303, to move left and right on the top of the support plate 301. This allows the abutment plate 304 to abut against the outside of the template, reinforcing the side template to the outside of the concrete. A slider 306 is fixedly installed on the bottom of the abutment plate 304, allowing the slider 306 to slide within the groove 305 on the top of the support plate 301. The bottom of the slider 306 is fixedly connected by a connecting block 307 that fits against the bottom of the support plate 301. When the position is moved, the slider 306 and the connecting block 307 will move together inside the groove 305, so that the abutment plate 304 can be horizontally pressed against the outside of the template to reinforce the template. The slide rod 308 is fixedly installed on the left side of the abutment plate 304. The left side of the slide rod 308 is inserted into the inside of the fixed plate 302. When the abutment plate 304 moves left and right, it can drive the slide rod 308 to compress the spring 309 and move left and right inside the fixed plate 302, so that the abutment plate 304 can move horizontally left and right stably, achieving the effect of abutting and reinforcing the side of the template. The abutment plate 304 is in horizontal contact with the template, which can avoid the problem of deformation caused by the abutment plate 304 pressing the template, and effectively avoid the problem of grout leakage caused by template deformation.
[0030] Considering that the bottom of the template also needs support and reinforcement, please provide... Figure 1 and Figure 4 The specific structure of the lifting assembly 2 is disclosed. The lifting assembly 2 includes a threaded post 201 fixedly installed on the top of the support rod 11. A threaded sleeve 202 is threadedly connected to the outer surface of the threaded post 201. A rotating handle 203 is fixedly installed on the bottom of the outer surface of the threaded sleeve 202. The threaded sleeve 202 is fixedly installed on the bottom of the support plate 301.
[0031] Through the above technical solution, the threaded column 201 is welded and fixedly installed on the top of the support rod 11. By rotating the rotating handle 203, the threaded sleeve 202, which is threadedly connected to the outer surface of the threaded column 201, can be rotated, so that the threaded sleeve 202 can be adjusted up and down along the threaded column 201. The support plate 301 is fixedly installed on the top of the threaded sleeve 202. Thus, the up and down movement of the threaded sleeve 202 can drive the support plate 301 to be adjusted up and down together. When reinforcing the template of the crossbeam, the base 1 can be placed on the ground, and the position of the threaded sleeve 202 can be adjusted upward by rotating it. The support plate 301 is then placed against the bottom of the template to provide support and reinforcement for the bottom of the template.
[0032] Secondly, considering that the ground on which base 1 is placed may be uneven, causing the support column to tilt and making it impossible to provide vertical support and reinforcement for the formwork, the following is provided: Figure 1 and Figure 5 The specific structure of the adjustment component 4 is disclosed. The adjustment component 4 includes a threaded opening on the top of the base 1. An adjustment rod 401 is threadedly connected inside the threaded opening. The bottom of the adjustment rod 401 extends through to the bottom of the base 1 and is rotatably connected to a support block 402. A rotating component 403 is fixedly installed on the top of the adjustment rod 401.
[0033] There are four adjustment components 4, which are arranged in a rectangular array inside the base 1 and are used to adjust the height of the four corners of the base 1 respectively.
[0034] Through the above technical solution, four threaded openings are made at the four corners of the top of the base 1, and four adjusting rods are threaded into the inside of the threaded openings. Then, rotating the rotating part 403 at the top of the adjusting rod 401 can drive the support block 402 fixedly installed at the bottom of the adjusting rod 401 to move up and down. When one or more corners of the base 1 are placed on uneven ground, the support block 402 can be adjusted downwards to different heights by rotating the four adjusting rods 401 at the four corners by different numbers of turns, so that the support block 402 can be pressed against the ground, and the base 1 can be placed relatively horizontally on the ground. Then, the support rod 11 can provide horizontal support for the lifting component 2 and the reinforcing component 3, so that the reinforcing component 3 can be pressed relatively horizontally against the bottom of the template to reinforce the template.
[0035] In summary, the working principle of this utility model is as follows:
[0036] When reinforcing the outside of the template, the base 1 is placed on the ground. If one or more corners of the base 1 are not on an uneven surface, the support block 402 can be adjusted downwards by rotating the four adjusting rods 401 at the four corners by different numbers of turns, so that the support block 402 can rest against the ground. The base 1 is then placed relatively horizontally on the ground. The support rod 11 can then provide horizontal support for the lifting component 2 and the reinforcing component 3, so that the reinforcing component 3 can rest relatively horizontally against the bottom of the template to reinforce the template. By rotating and adjusting the position of the threaded sleeve 202 upwards, the support plate 301 is placed horizontally against the bottom of the template, achieving the effect of horizontal support and reinforcement of the bottom of the template, and preventing the template from being squeezed and deformed, which could cause grout leakage.
[0037] When the support plate 301 is placed against the bottom of the template for support and reinforcement, rotating the threaded rod 303 can move the abutment plate 304 to a position, so that the abutment plate 304 abuts against the outside of the template, reinforcing the side template to the outside of the concrete. The abutment plate 304 will also move the slider 306 and the connecting block 307 together inside the slide groove 305. At the same time, when the abutment plate 304 moves left and right, it can also move the sliding rod 308 to compress the spring 309 together inside the fixed plate 302, so that the abutment plate 304 can move horizontally left and right stably, achieving the effect of abutting and reinforcing the side of the template. The sliding rod 308 and the connecting block 307 can stably move the abutment plate 304, preventing the template from leaking grout.
