Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an air-filled sealing device for gaps at the base of walls and columns. Background Technology

[0002] When pouring concrete into the wall, aluminum corner strips are used to seal the bottom of the wall column base during the final forming process to ensure that the concrete can be formed smoothly.

[0003] Existing aluminum formwork for walls and columns uses corner strips to connect the bottom of the formwork, but due to difficulties in achieving complete ground leveling and elevation control, a 5mm gap is typically left between the corner strips and the ground in the formwork design. In practical applications, after the wall and column surfaces are installed and leveled, the gaps at the bottom of the corner strips need to be manually sealed with mortar. If the sealing is not tight or there are gaps, mortar leakage at the bottom will occur, leading to quality defects such as concrete bulging, looseness, pitting, and rotten roots at the base of the wall and column. On the other hand, manual sealing with mortar is also very labor-intensive, resulting in high labor intensity for workers. To address these shortcomings, we propose an inflatable sealing device for the gaps at the base of walls and columns. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 - Figure 4 An inflatable sealing device for gaps at the base of wall columns includes a main air cushion 1 positioned below a corner strip. The main air cushion 1 is a non-enclosed strip structure with an inflation port 101 on its side. Main wear-resistant pads 2 are located on both the upper and lower surfaces of the main air cushion 1, their shapes matching those of the main air cushion 1. When the main air cushion 1 is filled with gas, the upper and lower main wear-resistant pads 2 are tightly fitted to the bottom of the corner strip and the ground, respectively. End pad assemblies 3 are detachably installed at the open ends of the main air cushion 1 and the main wear-resistant pads 2. After the main air cushion 1, main wear-resistant pads 2, and end pad assemblies 3 are installed in the aforementioned connection relationship at the location requiring sealing, air can be injected into the main air cushion 1 through the inflation port 101. For example, an air pump or air cylinder can be used to inflate the main air cushion 1, causing the upper and lower main wear-resistant pads 2 to tightly fit against the bottom of the corner strip and the ground, achieving the sealing purpose. Compared to mortar sealing, this method is not only more convenient and simple to operate but also provides a better sealing effect.

[0021] Furthermore, the main wear-resistant pad 2 has several equally spaced fixing holes 201 on the side facing the corner strip. Fixing pins 202 for vertically penetrating the corner strip are fixedly inserted into the fixing holes 201, so that after the main air cushion 1, the main wear-resistant pad 2 and the end pad assembly 3 are installed, the workers can insert the fixing pins 202 through the corner strip into the fixing holes 201, thereby fixing the main air cushion 1 and the main wear-resistant pad 2, causing the sealing device to slip and preventing concrete leakage.

[0022] It should be noted that the upper and lower main wear-resistant pads 2 and the middle main air pad 1 are all made of lightweight and flexible materials. When not inflated, they can be folded and rolled up for easy handling. When installed, they are partially inflated and have a preliminary shape, making it easy to install on the corner mold with the fixing pin 202. When removing them, the air inlet 101 can be opened to retract them. The operation is simple and easy to transport between floors.

[0023] In this embodiment, the end pad assembly 3 includes two secondary wear-resistant pads 301 and one secondary air pad 302. The two secondary wear-resistant pads 301 are respectively fixedly disposed on the upper and lower surfaces of the secondary air pad 302, so that the end position can also achieve a sealing effect through the three-layer structure.

[0024] Furthermore, an air outlet pipe 102 is provided on the side of the main air cushion 1 facing the secondary air cushion 302, and an air inlet pipe 4 is fixedly provided on the secondary air cushion 302 facing the air outlet pipe 102. In this embodiment, a sealing ring is also fixedly provided on the inner wall of the air outlet pipe 102 so that the air inlet pipe 4 can achieve a sealed state when entering the air outlet pipe 102, thus preventing gas leakage. The left and right ends of the air inlet pipe 4 are located in the inner cavity of the secondary air cushion 302 and the inner cavity of the main air cushion 1, respectively, and both ends of the air inlet pipe 4 are open, so that when the end pad assembly 3 is installed in the end position, the air inlet pipe 4 on the secondary air cushion 302 can pass through the air outlet pipe 102 and be inserted into the main air cushion 1, thereby achieving communication with the interior of the main air cushion 1.

[0025] In order to enable the operator to control the opening and closing state of the air intake pipe 4, this application provides an air intake hole 401 on the air intake pipe 4, and a slide tube 5 is slidably connected inside the air intake pipe 4 along its length. The slide tube 5 is provided with a misalignment hole 501. When the end of the slide tube 5 close to the air outlet pipe 102 moves to the position of the air outlet pipe 102, the misalignment hole 501 and the air intake hole 401 are aligned, so that the operator can change the position of the misalignment hole 501 by controlling the movement of the slide tube 5, thereby switching the misalignment hole 501 and the air intake hole 401 between aligned and misaligned states, and realizing the opening and closing control of the air intake pipe 4.

[0026] Specifically, a drive rod 502 is fixedly provided at the end of the slide tube 5 away from the main air cushion 1, and an air guide tube 503 is fixedly provided on the side wall of the secondary air cushion 302. One end of the drive rod 502 extends laterally through the air guide tube 503 to the outside of the secondary air cushion 302. Similarly, in this embodiment, a sealing ring is fixedly provided on the inner side wall of the air guide tube 503 so that the drive rod 502 will fit tightly with the sealing ring when it passes through the air guide tube 503, achieving a sealing state. A threaded sleeve 504 is rotatably connected to the end of the drive rod 502 away from the slide tube 5. The threaded sleeve 504 is used to thread-connect with the air guide tube 503 so that the operator can drive the drive rod 502 by rotating the threaded sleeve 504, thereby driving the slide tube 5. A spring 505 is installed inside the air inlet pipe 4. Flanges are provided on the inner walls of both the air inlet pipe 4 and the slide pipe 5. The left and right ends of the spring 505 abut against the flanges of the slide pipe 5 and the air inlet pipe 4, respectively. In its natural state, the spring 505 is compressed, so that when the threaded sleeve 504 disengages from the air guide pipe 503, the spring 505 can eject the slide pipe 5 outwards, causing the misalignment hole 501 and the air inlet 401 to be misaligned. When the drive rod 502 is pushed into the auxiliary air cushion 302, the air inlet pipe 4 is opened, allowing the operator to simultaneously inflate the main air cushion 1 and the auxiliary air cushion 302 through the inflation port 101, making inflation more convenient.

[0027] The working principle and usage process of this utility model are as follows: First, use an air pump to inflate the air inlet 101, so that the main air cushion 1 is in a semi-inflated state. Then, install the main air cushion 1 and the main wear-resistant pad 2 at the bottom of the corner strip. At this time, the air outlet pipe 102 is in a closed state. Then, open the air outlet pipe 102 and install the end pad assembly 3 at the position of the air outlet pipe 102, so that the air inlet pipe 4 passes through the air outlet pipe 102 and is inserted into the main air cushion 1. Then, screw the threaded sleeve 504 onto the outer wall of the air guide pipe 503, and push the drive rod 502 towards the sliding tube 5 to move the sliding tube 5, so that the misalignment hole 501 and the air inlet 401 are aligned. Finally, use an air pump to inflate the main air cushion 1 and the secondary air cushion 302 again through the air inlet 101, so that the two main wear-resistant pads 2 are in contact with the bottom of the corner strip and the ground respectively. Then, insert the fixing pin 202 into the fixing hole 201 to fix the main air cushion 1 and the main wear-resistant pad 2 to the bottom of the corner strip, thus completing the installation process. This replaces mortar to achieve the sealing effect. The operation is convenient and simple, and the sealing effect is good.
