Description

Technical Field

[0001] This utility model is a welded structure for a perforated sleeve in civil defense, belonging to the field of civil defense engineering technology. Background Technology

[0002] Civil air defense engineering, also known as civil defense engineering, refers to underground protective buildings constructed separately to ensure the shelter of personnel and materials, civil air defense command, and medical rescue during wartime, as well as basements built in conjunction with above-ground buildings that can be used for air defense during wartime. Civil defense engineering is an important facility to prevent sudden enemy attacks, effectively shelter personnel and materials, and preserve war potential.

[0003] Publication number CN211525708U discloses a welded structure for a perforated sleeve in civil defense systems, which fixes a flange to cast steel reinforcement through welding. Specifically, the flange is formed by welding two semicircular rings, with each semicircular ring welded to the cast steel reinforcement. During construction, depending on the construction conditions, the semicircular rings can be welded to the cast steel reinforcement first, and then the two semicircular rings can be welded together; alternatively, the two semicircular rings can be welded together to form the flange first, and then welded to the cast steel reinforcement. This embodiment uses a flange composed of two semicircular rings, which reduces construction difficulty. However, this device can only be used on relatively thin walls. When drilling holes in thicker walls, the pipe needs to be inserted into the reinforced concrete wall. The influence of light inside the wall can cause the steel reinforcement to collide with the reinforced concrete wall during the pipe's passage. There is an urgent need for a welded structure for a perforated sleeve in civil defense systems to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a welded structure for a perforated sleeve in civil defense systems, thereby solving the problems mentioned in the background art. This utility model is highly practical. By attaching the mounting box to one side of a reinforced concrete wall, the operating rod is inserted into the hole in the reinforced concrete wall. After observing the position of the guide rod at the other end of the reinforced concrete wall, the pipe is sleeved on the guide rod, thereby pulling the pipe through the reinforced concrete wall. This avoids wear and tear on the pipe caused by the reinforcing steel bars inside the reinforced concrete wall.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a welded structure for a perforated sleeve in civil defense, comprising a reinforced concrete wall and a connecting pipe, wherein a mounting box is fixedly connected to the right end of the connecting pipe, an elastic ring is provided inside the mounting box, a limit ring is fixedly connected to the circumferential surface of the elastic ring, a guide rod is fixedly connected inside the elastic ring, and an operating rod is fixedly connected to the right end of the guide rod.

[0006] Furthermore, a protective pad is fixedly connected to the left end of the sticker box, and the protective pad is made of rubber material.

[0007] Furthermore, a handle is fixedly connected to the right end of the sticker box, and a threaded groove is provided on the left end of the guide rod.

[0008] Furthermore, the elastic ring is made of rubber material, and the limiting ring is slidably connected inside the adhesive box.

[0009] Furthermore, the surface of the guide rod is provided with a rubber layer.

[0010] Furthermore, the right end of the operating lever has a circular structure.

[0011] The beneficial effects of this utility model: The welded structure of the perforated sleeve for civil defense of this utility model, due to the addition of a patch box, elastic ring, operating rod, limiting ring and guide rod, has shown through our design improvement and actual use that the device has a reasonable structure and good practicality. By attaching the patch box to one side of the reinforced concrete wall, the operating rod is inserted into the hole in the reinforced concrete wall. After observing the position of the guide rod at the other end of the reinforced concrete wall, the pipe is pulled through the reinforced concrete wall by fitting it onto the guide rod, which can avoid the steel bars in the reinforced concrete wall from causing wear to the pipe.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a welded structure for a perforated sleeve in civil defense, comprising a reinforced concrete wall 1 and a connecting pipe 8. A mounting box 3 is fixedly connected to the right end of the connecting pipe 8. An elastic ring 4 is provided inside the mounting box 3. A limit ring 6 is fixedly connected to the circumferential surface of the elastic ring 4. A guide rod 5 is fixedly connected inside the elastic ring 4. An operating rod 2 is fixedly connected to the right end of the guide rod 5. This design solves the problem that the original device can only be used for operation on relatively thin walls. When drilling holes in thicker walls, it is necessary to insert the pipe into the reinforced concrete wall 1. The influence of light inside the wall can cause the reinforcing steel to collide with the reinforced concrete wall 1 during the process of the pipe passing through the wall.

[0021] In the first embodiment of this utility model: a protective pad 7 is fixedly connected to the left end of the mounting box 3. The protective pad 7 is made of rubber material. The protective pad 7, located on the left side of the mounting box 3, can reduce wear and tear on the mounting box 3 caused by the wall. The protective pad 7, made of rubber, can separate the reinforced concrete wall 1 and the mounting box 3, thereby increasing the service life of the mounting box 3. A handle is fixedly connected to the right end of the mounting box 3. A threaded groove is opened on the left end of the guide rod 5. The handle on the right side of the mounting box 3 allows the worker to hold the handle and attach the mounting box 3 to the wall, thereby increasing the stability of the guide rod 5. The threaded groove on the left side of the guide rod 5 increases the length of the guide rod 5 through a threaded connection. An elastic ring 4 is made of rubber material. A limiting ring 6 is slidably connected inside the mounting box 3. The elastic ring 4 is made of elastic material, which can prevent wear and tear on the guide rod 5 caused by the wall. The limiting ring 6, located inside the mounting box 3, can install the guide rod 5 inside the mounting box 3 for worker operation. A rubber layer is provided on the surface of the guide rod 5. The rubber layer on the surface of the guide rod 5 can reduce the impact damage to the guide rod 5 caused by the reinforcing steel. The right end of the operating lever 2 has a circular structure, which allows the worker to grip the operating lever 2 for operation.

[0022] As a second embodiment of this utility model: When drilling a hole in the reinforced concrete wall 1, it is necessary to weld the pipe to the steel bars inside the reinforced concrete wall 1. The hole is larger than the pipe, and the steel bars will be exposed, resulting in an uneven structure. First, on one side of the reinforced concrete wall 1, the guide rod 5 is inserted into the hole by holding the handle. Then, the connecting pipe 8 is slid into the hole and the protective pad 7 is placed against the surface of the wall. After observing the guide rod 5, the worker on the other side of the reinforced concrete wall 1 slides the pipe on the surface of the guide rod 5 and pushes it backward. Meanwhile, the worker on the other side pulls the mounting box 3 backward so that the pipe can pass through the reinforced concrete wall 1. Then, the pipe is installed on the steel bars inside the reinforced concrete wall 1 by welding.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
