Technical Field
[0001] The utility model relates to the technical field of building tools, and more specifically to a side formwork fastener for a cast-in-place concrete component. Background Art
[0002] In the field of concrete component formwork construction in construction projects, traditional square column buckles are more common for fastening the formwork of columnar components. Traditional square column buckles are usually composed of four single-arm bent plates and four fixing pins. The installation method is to place the four single-arm bent plates on the four sides of the square column, and then connect and fix them with fixing pins to form a closed hoop around the column to hold the column.
[0003] However, with the innovation and development of architectural design, the application of special-shaped columns such as hexagonal columns, cross columns, T-shaped columns, etc. is increasing. This traditional square column buckle has many inconveniences when facing special-shaped columns. Taking the hexagonal column as an example, it has six sides, which is quite different from the outline of the square column. The traditional square column buckle is difficult to fit tightly. If it is used forcibly, a lot of splicing and adjustment are required, which may involve cutting, bending and other modification work on the components, which not only increases the complexity of construction, but also increases the construction cost. Similarly, for cross columns and T-shaped columns, their shapes are complex, with protruding and recessed parts, and the curved shape of the traditional square column buckle cannot be adapted. Special treatment is required for the protruding and recessed parts, which makes it easy for the template to be fixed loosely, and it is difficult to provide all-round effective support, causing the template to be easily deformed during concrete pouring. For this reason, we propose a side template fastener for cast-in-place concrete components. Utility Model Content

[0021] Furthermore, two groups of slots 4 are provided in parallel on the top and bottom of one side of the elbow clamp 1 close to the adjustment plate 3. The slots 4 penetrate the corresponding wall surface of the elbow clamp 1 and are connected to the movable groove on the elbow clamp 1. Adjustment slots 5 are provided on the adjustment plate 3 at intervals. The adjustment slots 5 are in two rows. The two rows of adjustment slots 5 are staggered with each other, and the two rows of adjustment slots 5 correspond to the positions of the two groups of slots 4 on the elbow clamp 1 respectively.
[0022] In the present embodiment, after a plurality of groups of single boards are telescopically adjusted on the elbow clamp 1 through the adjustment plate 3 and then assembled and installed on the template through the elbows at both ends of the elbow clamp 1, the pin 8 is inserted into one of the two groups of slots 4 on the elbow clamp 1, so that the pin 8 can be inserted into the slot 4 on the elbow clamp 1 and the corresponding adjustment slot 5 on the adjustment plate 3, thereby limiting the extension of the single board. At the same time, the inner side contraction of the assembled single board is limited by the concrete casting template, so that the pin 8 can tighten and limit the concrete casting template after the multiple groups of single boards are assembled.
[0023] In this embodiment, the angle of the single board can be adjusted from the middle position through the adjustment component, and the adjustment angle can be limited according to the angles on both sides of the common special-shaped columns of the building, so that the angle formed by the adjusted single board is adapted to it. The common special-shaped columns include but are not limited to diamond columns, "T"-shaped columns, "X"-shaped columns, etc.
[0024] Furthermore, the adjustment component includes a connecting substrate 2, an adjustment block 6, a shielding plate 7, a limit piece and a telescopic piece, wherein the connecting substrate 2 is divided into two groups, the two groups of connecting substrates 2 are rectangular blocks on the side away from each other, and the two groups of connecting substrates 2 are circular blocks on the side close to each other. The circular blocks on the two groups of connecting substrates 2 are symmetrically arranged up and down, and the two groups of connecting substrates 2 are connected to the adjustment plates 3 at the corresponding positions on the side away from each other.
[0025] Furthermore, a telescopic member is provided on the bottom group of connection substrates 2 , and the telescopic member slides through the wall surface at a corresponding position of the top group of connection substrates 2 .

[0029] In this embodiment, the shielding plate 7 can protect the limiting member during long-term use to prevent the limiting member from being affected by external impurities and concrete.
[0030] Furthermore, the limiting member includes a limiting groove 10 and a limiting block 11. The limiting grooves 10 are arranged in a ring-shaped manner above a group of connecting substrates 2 at the top. The angle between two adjacent groups of limiting grooves 10 can be adjusted according to the angle between the two sides of the common special-shaped columns of the building. The limiting block 11 is fixedly installed on the bottom wall of the adjustment block 6.
[0031] In this embodiment, the top group of connection substrates 2 is rotated so that the limiting blocks 11 are snapped into the corresponding limiting grooves 10 on the connection substrates 2, thereby adjusting and fixing the angle between the two groups of connection substrates 2.
[0032] Furthermore, the telescopic member includes a fixed cylinder 9, a connecting shaft 12 and a telescopic adjustment member 15.

[0033] In the present embodiment, the adjusting block 6 and the connecting shaft 12 are connected to each other, and the connecting shaft 12 is adjusted inside the fixed tube 9 by the telescopic adjusting member 15, so that when it is necessary to adjust the angle between the two groups of connecting substrates 2, the user lifts the adjusting block 6 to separate the limit block 11 on the shielding plate 7 and the limit groove 10 on the top group of connecting substrates 2. At this time, after rotating the top group of connecting substrates 2 to adjust to the fitting position, the adjusting block 6 is released so that the telescopic adjusting member 15 drives the adjusting block 6 and the connecting shaft 12 to reset, so that the limit block 11 is snapped into the limit groove 10 on the top group of connecting substrates 2, thereby completing the angle adjustment and locking angle of the single board.
