Description

Technical Field

[0001] The utility model relates to the technical field of civil construction, in particular to a device for sealing and preventing slurry leakage at the bottom of an aluminum alloy template. Background Art

[0002] The anti-leakage slurry sealing device for the bottom of the aluminum alloy formwork is an innovative technology used in construction to improve the quality of concrete pouring. In my country, the construction industry is developing rapidly, and the requirements for construction quality and efficiency are getting higher and higher. Under this background, the anti-leakage slurry sealing device for the bottom of the aluminum alloy formwork came into being. The device is mainly composed of an aluminum alloy formwork and a sealing member. During the construction process, the aluminum alloy formwork is used as a mold for concrete pouring. Its surface is smooth, demoulding is convenient, and it can be reused, which greatly improves the construction efficiency. However, leakage is prone to occur at the part where the aluminum alloy formwork contacts the ground, affecting the molding quality of concrete. In order to solve this problem, a anti-leakage slurry sealing device for the bottom of the aluminum alloy formwork is designed. The sealing member is fixed at the bottom of the aluminum alloy formwork, which can effectively prevent the concrete slurry from flowing out. At the same time, a tight line of defense is formed to further prevent the occurrence of leakage. The application of the anti-leakage slurry sealing device for the bottom of the aluminum alloy formwork not only improves the quality of concrete pouring and ensures the structural safety of the building, but also improves the construction efficiency and reduces the construction cost.

[0003] According to the search of China Utility Model Publication No.: CN220036134U, a structure for sealing and preventing leakage of slurry at the bottom of an aluminum alloy formwork is disclosed. The structure of the utility model adopts a triangular wedge block and an EVA foot sponge. Through the characteristics of the EVA foot sponge rebounding under pressure, the slurry is effectively prevented from leaking out during concrete pouring, and the EVA foot sponge can be replaced once every three to five floors, saving construction costs and reducing complicated column foot sealing procedures. The structure of the utility model adopts foot sponge sealing, which can increase the aesthetics of concrete molding, reduce the generation of garbage in the standard layer, have a better sealing effect, greatly reduce the phenomenon of concrete leakage, and save unnecessary labor and cost waste.

[0004] However, there are some issues that need to be considered when implementing the above technical solution: first, the structure uses EVA presser foot sponge for sealing, which needs to be replaced after multiple uses, causing waste, and due to the different widths of the gap between the bottom of the template and the ground, the sealing effect is unstable, and the unpressed part is still prone to leakage. Secondly, using a triangular wedge block to fix the EVA presser foot sponge will cause the EVA presser foot sponge to be damaged, resulting in leakage, and manual operation is labor-intensive and inefficient.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides an embodiment: a device for sealing and preventing leakage of slurry at the bottom of an aluminum alloy formwork, comprising an aluminum formwork 1 and a sealing mechanism 3, a connecting flange 2 is arranged on the front of the aluminum formwork 1, a sealing mechanism 3 is arranged on the inner side of the connecting flange 2, a partition 301 is arranged on the inner side of the connecting flange 2, and a mounting plate 302 is arranged below the partition 301.

[0026] Specifically, the partition 301 is welded to the aluminum template 1 and the connecting flange 2, the mounting plate 302 matches the size of the partition 301, the mounting plate 302 is connected to the partition 301 through the mounting bolts 303, and the mounting plate 302 is installed on the partition 301 through the mounting bolts 303, which is convenient for repair and replacement after damage.

A limiting groove 305 is provided behind the support bolts 304. The support bolts 304 are rotated to adjust the exposed length.

[0028] Specifically, the bottom of the partition 301 is connected to one end of the spring 306, and multiple groups of springs 306 are arranged. The other end of the spring 306 is connected to a connecting plate 307. An airbag 308 is arranged on the outside of the connecting plate 307. The airbag 308 forms a movable structure with the partition 301 through the spring 306. The airbag 308 is consistent in shape with the limiting groove 305. The airbag 308 is made of rubber. After the airbag 308 is inflated, it passes through the limiting groove 305 to fill the gap between the aluminum template 1 and the ground. At the same time, the spring 306 is stretched by force. After being deflated, the spring 306 is unloaded and reset, and the airbag 308 is lifted and retracted through the connecting plate 307 to prevent the airbag 308 from being damaged during the process of disassembling and assembling the template.

The connecting pipe 311 and the air pump 312 are threadedly connected. Multiple groups of air pumps 312 can be set according to needs.

After the aluminum template 1 is supported, avoid all the weight of the template being pressed on the airbag 308 to cause damage to the airbag 308. When multiple templates are used, the connecting pipe 311 can be used to connect the connecting ports 309 of adjacent airbags 308 to facilitate inflation and reduce the number of air pumps 312 used. Then use the blocking cap 310 to seal the end The connecting port 309 is blocked to prevent air leakage, and then the air pump 312 works to inflate the airbag 308 through the connecting pipe 311 and the connecting port 309. After the airbag 308 is inflated, it passes through the limiting groove 305 to fill the gap between the aluminum formwork 1 and the ground. At the same time, the spring 306 is stretched.
