AI Technical Summary
In the existing technology, the welded structure of the perforated sleeve for civil defense is difficult to install inside the flange because the flange is misaligned when installed on the reinforcing bars.
The positioning components include a bonding plate, a support rod, a positioning tube, and a positioning sleeve. The sleeve is positioned by aligning it at both ends of the air-raid shelter wall to prevent it from shifting. A wide tube guides the sleeve through the positioning tube, and rubber material is used to protect the sleeve from scratches and corrosion.
This enabled the sleeve to be installed smoothly inside the air-raid shelter wall, avoiding displacement, improving the stability and comfort of the installation, and protecting the safety of workers.

[0018] 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.
[0019] Please see Figures 1-4This utility model provides a technical solution: a welded structure for a perforated sleeve in civil defense, including a civil defense wall 1. Positioning components are provided at both ends of the civil defense wall 1. One set of positioning components includes an adhesive plate 7, a support rod 5, a positioning tube 4, and a positioning sleeve 2. The adhesive plate 7 is disposed on the surface of the civil defense wall 1. The support rod 5 is fixedly connected to the upper end of the adhesive plate 7. The positioning tube 4 is fixedly connected to the upper end of the support rod 5. The positioning sleeve 2 passes through and is slidably connected to the civil defense wall 1 and the positioning tube 4. This design solves the problem that in the original device, the flange was only installed on the reinforcing steel bars inside the civil defense wall. Due to the uneven layers of the reinforcing steel bars, the flange shifted during installation, making it difficult to install the sleeve inside the flange.
[0020] As the first embodiment of this utility model: A wide tube 3 is fixedly connected to the right end of the positioning tube 4. The surface of the wide tube 3 has a rounded corner structure. The wide tube 3 installed on the surface of the positioning sleeve 2 can guide the positioning sleeve 2 into the positioning tube 4, so that the positioning sleeve 2 passes through the air-raid shelter wall 1 through the positioning tube 4. The rounded corner structure on the surface of the wide tube 3 can prevent workers from being scratched when handling the wide tube 3. A protective sleeve 6 is fixedly connected to the circumferential surface of the support rod 5. The protective sleeve 6 is made of rubber material. The protective sleeve 6 installed on the surface of the support rod 5 can prevent workers from being corroded by hand sweat when handling it, and can also increase the comfort of the surface of the support rod 5. Both bonding plates 7 have a rubber layer on their surfaces. The rubber layer on the surface of the bonding plates 7 can allow the bonding plates 7 to adhere to the surface of the air-raid shelter wall 1, while preventing the steel bars inside the air-raid shelter wall 1 from slipping on the bonding plates 7. The positioning tube 4 is aligned with the through hole on the surface of the air-raid shelter wall 1. By aligning the positioning tube 4 with the through hole in the air-raid shelter wall 1, the positioning sleeve 2 can simultaneously penetrate both the air-raid shelter wall 1 and the positioning tube 4. The bonding plate 7 is bonded to the air-raid shelter wall 1. By bonding the bonding plate 7 to the air-raid shelter wall 1, the positioning tube 4 and the air-raid shelter wall 1 are positioned.
[0021] As a second embodiment of this utility model: First, holes are drilled inside the air-raid shelter wall 1, and the steel bars inside the air-raid shelter wall 1 are exposed to form a circular structure. Two sets of bonding plates 7 are respectively bonded to both ends of the air-raid shelter wall 1. Then, two sets of positioning tubes 4 are aligned with the through holes on the surface of the air-raid shelter wall 1, so that the positioning sleeve 2 passes through the two positioning tubes 4 and the air-raid shelter wall 1. The positioning sleeve 2 is welded to the steel bars inside the air-raid shelter wall 1. Finally, the two sets of positioning components are loosened from the positioning sleeve 2.
[0022] 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.
