Description

Technical Field

[0001] This application belongs to the field of building construction technology, specifically a protective plate for pouring concrete floor slabs with adjustable height. Background Technology

[0002] A concrete floor slab is a horizontal load-bearing component in a building structure that separates upper and lower floors. It is usually made of reinforced concrete and its thickness is designed according to the building's functional requirements (e.g., the thickness of a residential living room floor slab is usually 8-12cm, while it can reach 15-20cm in areas with larger loads). Its main function is to bear the floor load and transfer it to the beams and columns. Concrete floor slabs often require the use of protective plates during the pouring process because concrete is fluid. If there is no obstruction along the edge of the floor slab, the concrete will flow outward, resulting in inaccurate dimensions and inconsistent thickness of the floor slab edge, and even leakage. Protective plates, as vertical baffles set along the edge of the floor slab, can enclose the pouring space that matches the design dimensions, ensuring that the concrete is formed within the limited area.

[0003] Existing concrete slab pouring guards are mostly rigid structures with a fixed height, which only matches the specific slab thickness. When encountering slab pouring requirements of different thicknesses, it is necessary not only to stock guards of various specifications, but also to frequently replace guards before construction to adapt to the corresponding pouring dimensions, which prolongs the construction preparation time. While some adjustable guards can achieve height changes, the adjustment process is relatively cumbersome, often requiring the removal of multiple bolts before re-fixing, which is inconvenient and inefficient. Therefore, a concrete slab pouring guard that is easy to adjust in height is provided. Utility Model Content

[0004] The purpose of this application is to provide a protective plate for pouring concrete floor slabs that is easy to adjust in height, in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: a protective plate for concrete floor slab pouring that is easy to adjust in height, including a floor slab pouring bottom formwork, wherein multiple protective plates are provided on the sides of the floor slab pouring bottom formwork, and an adjustment mechanism connected to the protective plates is provided on the bottom surface of the floor slab pouring bottom formwork.

[0006] The adjustment mechanism includes a threaded slider, an adjusting screw, a bearing seat one, a sprocket one, a bearing seat two, a main shaft, and a sprocket two. A threaded slider is fixedly installed on the side of the guard plate near its bottom end. The adjusting screw is threadedly connected to the middle of the threaded slider. A bearing seat one corresponding to the adjusting screw is fixedly installed on the bottom surface of the floor slab casting mold. The top end of the adjusting screw is fixedly installed in the middle of the bearing seat one, and a sprocket one is fixedly installed at the bottom end of the adjusting screw. A limiting mechanism connected to the floor slab casting mold is provided on one side of the guard plate. A bearing seat two is fixedly installed on the bottom surface of the floor slab casting mold. A main shaft is fixedly installed in the middle of the bearing seat two. A sprocket two is fixedly installed on the outer surface of the main shaft. Both sprocket one and sprocket two have chains on their outer surfaces.

[0007] In a preferred embodiment, the limiting mechanism includes a mounting bracket and a limiting rod. The mounting bracket is fixedly installed on the side of the guard plate near the bottom end. The limiting rod is movably inserted through the middle of the mounting bracket, and the top end of the limiting rod is fixed to the bottom surface of the floor slab casting formwork.

[0008] In a preferred embodiment, a sealing connecting plate is fixedly installed at one end of each of the multiple protective plates that are close to each other by bolts.

[0009] In a preferred embodiment, a sealing gasket is fixedly installed on the side of the bottom formwork for floor slab casting.

[0010] In a preferred embodiment, a rotating handwheel is fixedly installed at the bottom end of the main rotating shaft.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0012] 1. In this application, due to the adoption of the above-mentioned scheme, the personnel first drive the main shaft to rotate by turning the handwheel. The sprocket two on the main shaft drives the sprocket one at the bottom of each adjusting screw to rotate synchronously through the chain, so that the adjusting screw rotates stably in the bearing seat one. At this time, the threaded slider connected to the adjusting screw will drive the guard plate to rise and fall vertically along the limiting rod of the limiting mechanism, so as to realize the synchronous adjustment of the height of the guard plate, thereby adapting to the pouring requirements of floor slabs of different thicknesses. During the adjustment process, the sealing connection plate and the sealing gasket can maintain the seal, effectively preventing grout leakage and ensuring the quality of floor slab forming.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] refer to Figures 1-5 As shown, a height-adjustable protective plate for concrete slab pouring includes a slab pouring bottom formwork 1. Multiple protective plates 2 are provided on the sides of the bottom formwork 1. Sealing connection plates 5 are fixed to the ends of the multiple protective plates 2 that are close to each other by bolts. Sealing gaskets 6 are fixedly installed on the sides of the bottom formwork 1. An adjustment mechanism 3 connected to the protective plates 2 is provided on the bottom surface of the bottom formwork 1. A supporting keel is provided at the bottom of the bottom formwork 1 to effectively maintain the overall stability of the bottom formwork 1. The protective plates 2 have a total of four... Each of the four sides of the bottom formwork 1 for floor slab pouring is connected to form a complete floor slab pouring space. The sealing connection plate 5 between adjacent protective plates 2 enhances the sealing performance and prevents grout leakage due to gaps during pouring. A sealing connection gasket is installed at the end of the sealing connection plate 5 near the protective plate 2. When the protective plate 2 is installed, it will squeeze the sealing connection gasket to achieve a seal. At the same time, the sealing gasket 6 on the side of the bottom formwork 1 for floor slab pouring can improve the sealing effect at the contact point between the protective plate 2 and the bottom formwork 1 for floor slab pouring, further preventing concrete leakage and ensuring the forming quality of the floor slab edge.

[0021] refer to Figures 1-5As shown, the adjustment mechanism 3 includes a threaded slider 301, an adjusting screw 302, a bearing seat 303, a sprocket 304, a bearing seat 305, a main shaft 306, and a sprocket 307. A threaded slider 301 is fixedly installed on the side of the guard plate 2 near its bottom. The adjusting screw 302 is threadedly connected to the middle of the threaded slider 301. A bearing seat 303 corresponding to the adjusting screw 302 is fixedly installed on the bottom surface of the floor slab casting mold 1. The top end of the adjusting screw 302 is fixedly installed in the middle of the bearing seat 303. Through the threaded engagement between the threaded slider 301 and the adjusting screw 302, the rotational motion of the adjusting screw 302 can be converted into the vertical lifting motion of the guard plate 2, achieving height adjustment. The bearing seat 303 provides stable support for the adjusting screw 302, ensuring that it does not wobble during rotation and improving the smoothness and accuracy of the adjustment process.

[0022] refer to Figures 1-5 As shown, a sprocket 304 is fixedly installed at the bottom end of the adjusting screw 302. A limiting mechanism 4 connected to the floor slab casting bottom mold 1 is provided on one side of the guard plate 2. A bearing seat 305 is fixedly installed on the bottom surface of the floor slab casting bottom mold 1. A main rotating shaft 306 is fixedly installed in the middle of the bearing seat 305. A rotating handwheel 7 is fixedly installed at the bottom end of the main rotating shaft 306. A sprocket 307 is fixedly installed on the outer surface of the main rotating shaft 306. Both the sprocket 304 and the sprocket 307 are provided with chains on their outer surfaces. The rotating handwheel 7 facilitates the rotation of the main rotating shaft 306. Through the transmission of the sprocket 307, the chain, and the sprocket 304, multiple adjusting screws 302 can be rotated synchronously, realizing the synchronous height adjustment of the four guard plates 2. This avoids the problem of inconsistent height caused by individual adjustment and greatly improves the adjustment efficiency. The bearing seat 305 ensures the stable rotation of the main rotating shaft 306, while the chain drive ensures the reliability of power transmission.

[0023] refer to Figures 1-5 As shown, the limiting mechanism 4 includes a mounting support 401 and a limiting rod 402. The mounting support 401 is fixedly installed on the side of the guard plate 2 near the bottom end. The limiting rod 402 is movably inserted through the middle of the mounting support 401. The top of the limiting rod 402 is fixed to the bottom surface of the floor slab casting bottom formwork 1. Through the cooperation between the limiting rod 402 and the mounting support 401, the lifting and lowering of the guard plate 2 is facilitated and limited, preventing the guard plate 2 from tilting or shifting during the adjustment process, ensuring that the guard plate 2 always remains vertical. This not only improves the accuracy of height adjustment but also enhances the stability of the guard plate 2 against the lateral pressure of concrete during casting.

[0024] The implementation principle of this application's embodiment of a height-adjustable concrete floor slab pouring guard plate is as follows: During normal use, the floor slab pouring bottom formwork 1 and the four guard plates 2 together form a floor slab pouring platform, facilitating concrete pouring operations on the floor slab pouring bottom formwork 1. When it is necessary to adjust the four guard plates 2 to a suitable height, firstly, the handwheel 7 is turned to drive the main shaft 306 to rotate. The sprocket 2 307 on the main shaft 306 drives the sprocket 1 304 at the bottom of each adjusting screw 302 to rotate synchronously via a chain, causing the adjusting screw 302 to rotate stably within the bearing seat 1 303. At this time... The threaded slider 301, which is threadedly connected to the adjusting screw 302, will drive the guard plate 2 to rise and fall vertically along the limiting rod 402 of the limiting mechanism 4, so as to realize the synchronous adjustment of the height of the guard plate 2, thereby adapting to the pouring requirements of floor slabs of different thicknesses. During the adjustment process, the limiting rod 402 can effectively ensure that the guard plate 2 does not tilt. The sealing connecting plate 5 and the sealing gasket 6 always maintain the sealing state between the guard plates 2 and between the guard plate 2 and the bottom formwork 1 of the floor slab pouring. After the adjustment is in place, concrete can be poured. The guard plate 2 encloses and forms a stable pouring space, which can effectively prevent grout leakage and ensure the quality of floor slab forming.
