Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum formwork production, and relates to a leak-proof structure at the bottom of an aluminum formwork. Background Art

[0002] During the construction process of aluminum formwork, due to the uneven working surface with high and low levels, there is often a gap of about 10 mm at the bottom of the wall columns. For this gap, the existing method is to mix cement mortar on-site for plugging during construction. However, this method has the following disadvantages:

[0003] 1. Plugging with cement mortar from the outside cannot control the plugging quality, and it is easy to cause cavities and rotten roots on the concrete forming surface;

[0004] 2. If the cement mortar plugging is not in place, it is easy to leak slurry, resulting in waste and increasing the subsequent repair cost;

[0005] 3. Before the formwork is removed, it is necessary to knock out the cement mortar from the bottom of the formwork first, which is a large workload;

[0006] 4. The cement mortar becomes construction waste and is not easy to clean up.

[0007] In view of the above problems, we specifically designed a leak-proof structure, which can fill the gap between its bottom and the working surface when the working surface of the aluminum formwork is uneven, thereby preventing the slurry from leaking out. Summary of the Utility Model

[0008] The purpose of the utility model is to provide a leak-proof structure at the bottom of an aluminum formwork for the above-mentioned existing problems, aiming to fill the gap between its bottom and the working surface when the working surface of the aluminum formwork is uneven, thereby preventing the slurry from leaking out.

[0009] The purpose of the utility model can be achieved by the following technical solutions: A leak-proof structure at the bottom of an aluminum formwork, characterized in that it includes an aluminum formwork, and an angle aluminum and a rubber strip are successively arranged below the aluminum formwork from top to bottom. The rubber strip includes a cuboid base and a compression strip fixed to one side of the top of the base. There are several cavities in the compression strip; this leak-proof structure also includes several countersunk bolts, and through holes for the countersunk bolts to pass through are opened on the aluminum film plate, the angle aluminum and the base; springs are sleeved on each countersunk bolt, and each countersunk bolt successively tightens and fixes the aluminum formwork, the angle aluminum, the spring and the base together from top to bottom.

[0010] Preferably, notches are opened on the base at both ends of the rubber strip, and several anti-slip teeth are arranged at the bottom of the rubber strip.

[0011] The advantages of the utility model are:

[0012] 1. This leakage plugging structure is adopted to set a rubber strip with appropriate deformability at the bottom of the aluminum formwork, so that it can adaptively deform under the action of the self-gravity of the aluminum formwork, thereby realizing the plugging of the bottom of the aluminum formwork, preventing the leakage of grout, saving pouring materials while making the pouring surface smoother and improving the construction quality.

[0013] 2. In this leakage plugging structure, it uses countersunk bolts and springs, so we can conveniently adjust the height of the bottom of the aluminum formwork. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following are specific embodiments of the present invention in combination with the drawings, and the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0019] As Figure 1 , Figure 2 and Figure 3 shown, a leakage plugging structure for the bottom of an aluminum formwork includes an aluminum formwork 1, and an angle aluminum 2 and a rubber strip are sequentially arranged from top to bottom below the aluminum formwork 1. The rubber strip includes a cuboid base 3 and a compression strip fixed to one side of the top of the base 3. There are several cavities 41 in the compression strip 4; this leakage plugging structure also includes several countersunk bolts 5, and through holes for the countersunk bolts 5 to pass through are opened on the aluminum formwork, angle aluminum 2 and base 3; springs 6 are sleeved on each of the countersunk bolts 5, and each of the countersunk bolts 5 tightly fixes the aluminum formwork 1, angle aluminum 2, spring 6 and base 3 together from top to bottom.

[0020] The working principle of this leakage plugging structure is as Figure 1 and Figure 2As shown, in actual application, the rubber strip of this leak plugging structure seals the gaps left at the bottom of the aluminum formwork 1 due to the uneven working surface, thereby avoiding the leakage of slurry during pouring and effectively preventing waste of materials. Moreover, the base 3 of the rubber strip and the bottom of the aluminum formwork 1 are tightened by a countersunk head bolt 5 sleeved with a spring 6. Therefore, we can adjust the plugging height by turning the bolt, enabling it to make adaptive adjustments according to the conditions of the installation surface at any time. Furthermore, on one side of the top of the base 3, there is a compression strip 4 with multiple cavities 41 inside. Thus, when the countersunk head bolt 5 is adjusted downward, it can be adaptively compressed downward and, under the action of its own elastic force, always tightly press against the bottom of the aluminum formwork 1. The angle aluminum 2 is used to position the rubber strip and seal the gap between the rubber strip and the aluminum formwork 1, making its sealing performance better. This leak plugging structure adopts a rubber strip with appropriate deformability at the bottom of the aluminum formwork 1, enabling it to adaptively deform under the action of the self-weight of the aluminum formwork 1, thereby realizing the plugging of the bottom of the aluminum formwork 1, preventing slurry leakage, saving pouring materials, making the pouring surface smoother, and improving the construction quality.

[0021] As Figure 3 shown, notches 7 are provided on the base 3 at both ends of the rubber strip, and a number of anti-slip teeth 8 are provided at the bottom of the rubber strip. The notches 7 are provided to facilitate the staff to measure the elevation when installing the aluminum formwork 1, and the anti-slip teeth 8 can prevent the rubber strip from sliding due to the pouring pressure, further ensuring the sealing performance of this leak plugging structure.

[0022] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art of the present utility model can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
