However, it is inevitable that quality defects such as misalignment and leakage will occur after the concrete components are cast and formed, which seriously affects the visual quality of the concrete project. In the traditional construction process, the installation of wooden formwork is to cut the formwork into appropriate sizes and then assemble it. The level of the operators directly affects the assembly effect. The formwork assembly of some projects is not strict and exceeds the allowable deviation of the specification. After the concrete is poured, it is very easy to cause leakage, misalignment and other quality defects. Utility Model Content

The rotating plate 33 can play a role of locking and releasing. The locking structure 3 is used to fix the template 1 and the connecting structure 2.

[0031] The first embodiment is a concrete construction joint fixing device, which is clamped on the template 1, the thickness of the template 1 is 14 mm, and a tenon 11 is provided on the template 1. The size of the tenon 11 matches the size of the center plate 22.

The locking structure 3 is provided on the connecting structure 2, and the locking structure 3 is used to fix the connecting structure 2 when it is inserted into the template 1.

[0032] This embodiment adopts a cross-shaped connection structure 2, which can connect four templates 1 and then fix them through a locking structure 3. This embodiment is used when building walls over a large area and can effectively connect the four templates 1 tightly.

[0033] The second embodiment, as Figure 4 As shown, a concrete construction joint fixing device is clamped on a template 1, the thickness of the template 1 is 14 mm, a tenon 11 is provided on the template 1, the size of the tenon 11 matches the size of the center plate 22, the tenon 11 is used to be inserted into the inside of the connecting structure 2, including: a connecting structure 2 and a locking structure 3, the connecting structure 2 is inserted on the template 1, the connecting structure 2 is used to connect other templates 1, the locking structure 3 is provided on the connecting structure 2, and the locking structure 3 is used to fix the connecting structure 2 when it is inserted into the template 1.

[0034] Compared with the first embodiment, this embodiment reduces the connection between the two templates 1. It is practical when the area is not as large as the wall building area in the first embodiment. The two templates 1 are connected by plugging up and down and are also fixed by the locking structure 3. The effect is the same as that of the first embodiment.

[0036] This embodiment is mainly used when building wall corners. Two templates 1 are plugged into the template 1 horizontally and vertically, and then fixed by a locking structure 3. Generally, the connection of the templates 1 at the corners is often accompanied by loose assembly and exceeding the allowable deviation of the specification. After the concrete is poured, it is very easy to cause quality defects such as leakage and misalignment. However, due to the fixation and intervention of the connection structure 2, similar situations will not occur, ensuring the stability and cleanliness of the wall.
