[0019] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION Example
[0020] refer to Figure 1 、 Figure 2 and Figure 3 An embodiment of the present utility model proposes a building wood formwork joint fixing clamp, comprising: a pad 1, a pressure plate 4 and a pin piece 6; a locking plate 2 is vertically arranged on the back side of the pad 1, and a first long hole 3 is provided on the locking plate 2; a second long hole 5 is provided on the pressure plate 4, and the pressure plate 4 is used to press the back side of the pad 1, and the locking plate 2 passes through the second long hole 5; the pin piece 6 passes through the first long hole 3 to press the pressure plate 4.
[0021] The backing plate 1 can be made of a galvanized metal sheet with a width of 30mm and a thickness of 2.6mm. The length of the backing plate 1 is generally 100mm, but shorter lengths can be made as needed. One or more locking plates 2 are welded to the back of the backing plate 1. When splicing the wooden formwork 9, the backing plate 1 is placed between two adjacent wooden formworks 9, so that the locking plates 2 extend out of the wooden formworks 9. The pressing plate 4 is then inserted onto the locking plates 2 through the second elongated hole 5. The pin 6 is then inserted into the first elongated hole 3 on the locking plates 2. The pressing plate 4 and the backing plate 1 clamp the two adjacent wooden formworks 9 together, ensuring that the joints between the two adjacent wooden formworks 9 are aligned and prevent deformation. Finally, concrete 10 is poured into the inner side of the wooden formwork 9. When the concrete 10 has solidified, the pin 6 and the pressing plate 4 are removed, and finally, the wooden formwork 9 and the backing plate 1 are removed from the surface of the concrete 10. Example
[0022] refer to Figure 2 and Figure 3 On the basis of embodiment 1, it further includes a pad 7, which is used to pad under the pressure plate 4.
[0023] Placing the pad 7 between the pressing plate 4 and the wooden template 9 can facilitate installation and disassembly. The pad 7 can be made of wood or other weak elastic materials, and is placed under the pressing plate 4 and distributed on both edges of each second long hole 5. Example
[0024] refer to Figure 2 and Figure 3 On the basis of Example 1, the pressing plate 4 is a wooden board, and the pressing plate 4 is connected to the two edges of the second long hole 5 with pads 7, and the pads 7 are wooden blocks.
[0025] When a wooden board is used as the pressure plate 4, the pad 7 is also made of a wooden block. The pad 7 can be fixed to the two edges of the second long hole 5 on the pressure plate 4 by nails or screws to form an integrated structure, which can prevent the pad 7 from being lost. Example
[0026] refer to Figure 1 and Figure 2 On the basis of Example 1, a plurality of locking plates 2 are provided on each pad 1, and the plurality of locking plates 2 are aligned.
[0027] The pad 1 is generally about one meter long, and the length can be customized as needed. Multiple locking plates 2 are welded on the back of the pad 1, and the interval between every two locking plates 2 is 300mm, which can compress the pad 1 in sections. Example
[0028] refer to Figure 1 、 Figure 2 and Figure 3 Based on Example 1, the pin piece 6 is a triangular or trapezoidal structure with a large end and a small end.
[0029] The small end of the pin 6 passes through the first long hole 3 and then gradually presses against the first long hole 3 on the locking plate 2 through the inclined surface to press the pressing plate 4. Example
[0030] refer to Figure 1 、 Figure 2 and Figure 3 On the basis of embodiment 5, a through hole 8 is provided at the small end of the pin piece 6.
[0031] One or more through holes 8 are provided on the pin piece 6. After the pin piece 6 is inserted into the second long hole 5 on the locking piece 2, a short rod can be inserted into the through hole 8 of the pin piece 6 to prevent the pin piece 6 from falling off.
