Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a grout-proof column formwork for residential construction. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project, encompassing the construction process of various buildings. Column formwork refers to the molds used during building construction to cast concrete columns, primarily for shaping the geometric form of the concrete column and supporting the concrete pouring. In residential building construction, formwork is often used to shape and pour concrete into columns. However, square column formwork is typically composed of four panels joined together. During grouting, this type of formwork may experience grout leakage due to weak connections between the panels.

[0003] In related technologies, such as the patent for a leak-proof column formwork for residential construction (publication number CN212957629U), three movable rods are rotated to form a concave structure on the column formwork and placed on the corresponding mounting block. Then, the fixed rod and the movable rod can form a rectangular structure and be fixedly fitted onto the column formwork. At this time, the movable rod and the fixed rod are in close contact with the surface of the plate, which can strengthen the plate and improve the stability between the plates, preventing the plates from shaking and causing gaps between the plates to form during grouting.

[0004] However, the clamping structures such as reinforcing brackets and fastening rods in the aforementioned devices can only clamp and fix column formwork of fixed dimensions. In practical applications, column formwork sizes are numerous and complex, which necessitates the preparation or customization of a large number of clamping devices for each construction project. This not only increases construction costs but also causes inconvenience to on-site construction operations. Furthermore, because the clamping structure is tightly fitted to the column formwork, it is not very convenient to tighten in practice. Based on this, a leak-proof column formwork for residential construction is provided to solve the above problems. Utility Model Content

[0011] As a preferred embodiment of the anti-leakage column formwork for residential construction described in this utility model, the first pressure rod has a strip-shaped limiting groove on the side away from the second movable rod. The first pressure rod is placed on the inner side of the concave surface of the concave limiting rod. The outer end of the concave limiting rod is threadedly connected to a second adjusting screw, and the inner end of the second adjusting screw abuts against the inner side of the strip-shaped limiting groove.

[0012] As a preferred embodiment of the anti-leakage column formwork for residential construction described in this utility model, the tops of the first pressure rod and the second pressure rod are flush with each other, and the inner length stroke of the concave limiting rod matches the second limiting groove.

[0013] As a preferred embodiment of the anti-leakage column formwork for residential construction described in this utility model, the outer ends of the first adjusting screw and the second adjusting screw are also fixed with handles at a perpendicular angle to them.

The operation is simple. In summary, this column formwork structure effectively prevents and reduces grout leakage during pouring. Furthermore, the diameter of the hoop structure can be flexibly adjusted according to the actual outer dimensions of the column formwork, reducing construction costs and providing convenience for on-site construction operations. It is suitable for widespread application. Attached Figure Description

[0022] Figures 1-3 The diagram shown is a complete structural schematic of a grout-proof column formwork for residential construction according to this utility model. Please refer to [link / reference]. Figures 1-3 This embodiment of a residential construction anti-leakage column formwork includes a column formwork 100, which is a rectangular structure composed of four plates. Multiple hoop structures are provided along the height direction of the outer periphery of the column formwork 100. Each hoop structure includes a movable rod 200 and a movable rod 210 horizontally rotatably connected to one end of the movable rod 200. Sliding blocks 220 are attached to the distanced sections of the movable rods 200 and 210 along their length. A pressure rod 300 is horizontally hinged to the movable rod 210 via the sliding blocks 220. A pressure rod 400 is horizontally hinged to the movable rod 200 via the sliding blocks 220. A concave limiting rod 410 is fixed to the end of the pressure rod 400 facing away from the movable rod 200. The movable rods 200, 210, 300, and 400 are fitted together around the column formwork 100 by a locking structure.

[0023] The column formwork 100 comprises parallel, opposite X-axis side plates 110 and Y-axis side plates 120. The X-axis side plates 110 have slots 1101 at both ends that engage with the edges of the Y-axis side plates 120. It can be understood that this single-sided interlocking method provides better grout leakage prevention compared to traditional column formwork structures. One side of the movable rod 200 has a limiting groove 2001 that slides and matches the slider 220. One side of the movable rod 210 has a limiting groove 2101 that slides and matches the slider 220. One side of the slider 220 is fixed with a connecting block 230 that is horizontally rotatably connected to the pressure rod 300 and the pressure rod 400 respectively. The outer ends of the movable rod 200 and the movable rod 210 are threadedly connected with a first adjusting screw 240 that extends to the inner side of the limiting groove 2001 and the limiting groove 2101. The inner end of the first adjusting screw 240 abuts against the slider 220, and one side of the slider 220 has a circular groove corresponding to the end of the first adjusting screw 240. The pressure rod 300 has a strip-shaped limiting groove 3001 on the side away from the movable rod 210. The pressure rod 300 rests on the inner side of the concave surface of the concave limiting rod 410. The outer end of the concave limiting rod 410 is threadedly connected to a second adjusting screw 500, and the inner end of the second adjusting screw 500 abuts against the inner side of the strip-shaped limiting groove 3001. The tops of the pressure rod 300 and the pressure rod 400 are flush with each other, and the inner length stroke of the concave limiting rod 410 matches the limiting groove 2101. Specifically, in use, the column formwork 100 is initially placed around the perimeter of the reinforcing bars, utilizing the interlocking structure of the edge plates of the column formwork 100 to create a good grout leakage prevention effect. Then, movable rods 200 and 210 are placed at right angles to adjacent sides of the column formwork 100. Next, pressure rods 300 and 400 are rotated to another set of adjacent sides of the column formwork 100. With the cooperation of limiting slide grooves 2001 and 2101, and sliders 220, pressure rods 300 and 400 are moved to fit against the outer side of the column formwork 100. Tightening the first adjusting screw 240 and the second adjusting screw 500 ensures that the movable rod 1 200, movable rod 210, pressure rod 1 300, and pressure rod 2 400 fit tightly against the outer periphery of the column formwork 100, resulting in a firm bond and seal at the edge of the column formwork. The operation is simple. In summary, this column formwork structure effectively prevents and reduces grout leakage during pouring. Furthermore, the diameter of the hoop structure can be flexibly adjusted according to the actual outer dimensions of the column formwork, reducing construction costs and facilitating on-site construction operations. It is suitable for widespread application.

[0024] Furthermore, the outer ends of the first adjusting screw 240 and the second adjusting screw 500 are also fixed with handles at a perpendicular angle to them. It can be understood that the handles allow construction personnel to easily rotate, tighten, and loosen the first adjusting screw 240 and the second adjusting screw 500, saving time and effort.

[0025] In summary, this embodiment of a residential construction anti-grout leakage column formwork, when in use, involves initially surrounding the perimeter of the reinforcing steel bars with the column formwork 100, utilizing the interlocking structure of the edge plates of the column formwork 100 to create a good anti-grout leakage effect. Then, movable rod 1 200 and movable rod 210 are attached at right angles to adjacent sides of the column formwork 100. Next, pressure rod 1 300 and pressure rod 2 400 are rotated to another set of adjacent sides of the column formwork 100. With the cooperation of limiting slide groove 1 2001, limiting slide groove 2101, and slider 220, pressure rod 1 300 and... The second pressure rod 400 is moved to fit against the outside of the column formwork 100. Then, the first adjusting screw 240 and the second adjusting screw 500 are tightened, so that the first movable rod 200, the second movable rod 210, the first pressure rod 300 and the second pressure rod 400 fit tightly against the outer periphery of the column formwork 100. This ensures that the edge of the column formwork is firmly bonded and sealed. The operation is simple, and this column formwork structure can effectively prevent and reduce grout leakage during the pouring process. At the same time, the diameter of the hoop structure can be flexibly adjusted according to the actual outer dimensions of the column formwork.
