Description

Technical Field

[0001] This utility model belongs to the field of construction, and in particular relates to a device for fixing an internal insulation board in the formwork of a hydraulic concrete dam. Background Technology

[0002] In cold regions, to prevent temperature cracks caused by sudden drops in temperature after concrete pouring, which could lead to splitting cracks after water is impounded, insulation materials are applied to the upstream and downstream faces of the dam throughout the construction period. The insulation material should be tightly adhered to the protected surface, and the insulation standard should be reasonably determined based on the temperature of the construction area. Insulation methods include pasting insulation boards. The conventional method involves installing insulation boards on the exterior of the dam using suspended platforms or similar tools after each concrete pour, which often presents safety hazards such as overlapping work on different surfaces and working at height. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a device for fixing the built-in insulation board of the formwork for the lifting of hydraulic concrete dams.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A device for fixing an internal insulation board in a hydraulic concrete dam formwork lifting platform includes several lower fixing components and several side fixing components. The lower fixing components are located at the bottom of the lifting platform and connected to the insulation cup. The side fixing components are located on both sides of the insulation board and connected to the lifting platform.

[0006] The side fixing assembly includes a limiting member, a connecting plate, a second screw, and a fixing nut. The limiting member has an inverted L-shaped structure and is located on one side of the lifting template and the insulation board. One side of the connecting plate is connected to the limiting member. The second screw passes through the connecting plate, the lifting template, and the insulation board in sequence and is connected to the fixing nut. The connecting plate has screw holes to facilitate the installation of the second screw.

[0007] Furthermore, the limiting component includes a limiting end and a fixing end. The limiting end is located on one side of the lifting template and the insulation board and is provided with a second adjustment groove. The fixing end is located on one side of the insulation board. One end of the connecting plate is provided with a connector, which cooperates with the second adjustment groove.

[0008] Furthermore, the second screw has several cut-off recesses. If the screw is rusted or cannot be pulled out, force can be applied to both ends simultaneously to break the second screw from the cut-off recesses, and then it can be removed from both ends.

[0009] Furthermore, the fixing nut is equipped with a hand-held disc, which facilitates breaking off the second screw and pulling it out.

[0010] Furthermore, the length of the second adjusting groove is greater than the thickness of the insulation board.

[0011] Furthermore, the lower fixing component includes a clamping plate, a support plate, and a first screw. The support plate is fixed to the bottom of the tilting template and is provided with a first adjustment groove. The clamping plate has an L-shaped structure, with one end of the clamping plate placed in the first adjustment groove. The first screw passes through the clamping plate and the insulation plate and is connected to the tilting template.

[0012] Furthermore, the length of the first adjusting groove is less than the thickness of the insulation board.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] The hydraulic concrete dam lifting formwork built-in insulation board fixing device of this utility model is equipped with both a lower fixing component and a side fixing component. It can accurately fix the insulation board in the designated position of the lifting formwork to prevent displacement. At the same time, it is easy to install and disassemble and can be reused repeatedly. Attached Figure Description
