Abstract
Description
Technical Field
[0001] This utility model relates to the field of duct installation technology, specifically to a duct through-wall installation device. Background Technology
[0002] As an important piece of equipment for treating malignant tumors in hospitals, the particle linear accelerator works by generating high-energy X-rays that directly target the lesion and kill the tumor. During operation, a small amount of radioactive gas may be generated in the room, requiring continuous ventilation to ensure that the environment does not harm patients and staff. If the reserved opening in the air duct is a conventional straight shape, X-rays will leak out, posing a great safety hazard. The structural design optimizes the reserved opening in the wall by designing it in a 90° "Z" shape, which greatly improves the radiation protection effect.
[0003] The existing zigzag openings are constructed using traditional formwork and scaffolding. Once the concrete is poured in one go, they cannot be removed. Furthermore, the narrow interior of the zigzag openings means that the ducts can only be installed in sections, which leads to a series of problems such as the inability to connect the joints in the middle of the ducts, the inability to install the outer insulation, and the inability to fix the ducts.
[0004] Therefore, a duct penetration wall installation device is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a duct wall-penetrating installation device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A duct through-wall installation device includes a wall, with side walls fixedly installed on both sides of the wall, a groove provided on one side of the wall, a steel template provided inside the wall, a casting component provided inside the wall, a protective component provided inside the steel template, and an installation component provided inside the steel template.
[0008] Furthermore, the casting assembly includes several longitudinal reinforcing ribs fixedly installed on the top surface of the wall, several transverse reinforcing ribs fixedly installed on the inner wall, and fixing plates fixedly connected to both sides of the outer surface of the steel formwork.
[0009] Furthermore, the longitudinal stiffeners and transverse stiffeners are equidistantly staggered, and the other ends of the longitudinal stiffeners and transverse stiffeners are fixedly connected to the outer surface of the steel formwork.
[0010] Furthermore, the protective component includes an inner cavity disposed inside the steel template, a partition plate is welded to the middle position of the inner wall of the inner cavity, and several fixing clips are fixedly installed on the inner wall of the inner cavity and the outer surface of the partition plate respectively.
[0011] Furthermore, the installation assembly includes an insulated sheet metal plate installed inside the inner cavity, the insulated sheet metal plate having a pipe installation groove inside, an air duct being fixedly installed inside the pipe installation groove, and a fixing ring being fixedly connected to one end of the insulated sheet metal plate.
[0012] Furthermore, the air duct is configured in multiple sections, with angle steel flanges fixedly connected between each section, and the air duct is symmetrically distributed on both sides of the inner cavity.
[0013] The beneficial effects of this utility model are as follows:
[0014] This invention involves attaching an insulated sheet metal plate to the outside of the ductwork, installing it inside a steel formwork, and then installing the entire steel formwork inside the wall and pouring concrete. This effectively disperses the concentrated stress at the ductwork's penetration point, providing a direct and reliable reinforcement effect. It ensures that the concrete is formed in one pour, and after the steel formwork is poured, it is tightly integrated with the wall reinforcement, enhancing the overall structure and reducing later maintenance requirements. By installing angle steel flanges between different sections of the ductwork, the ease of installation and efficiency are improved. Attached Figure Description

The longitudinal reinforcing ribs 401 and the transverse reinforcing ribs 402 are equidistantly staggered, and the other ends of the longitudinal reinforcing ribs 401 and the transverse reinforcing ribs 402 are fixedly connected to the outer surface of the steel formwork 405.
[0026] More specifically, the steel formwork 405 is entirely welded, and all welds are full welds, which can prevent concrete from entering the interior of the steel formwork 405 when pouring concrete. The outer surface of the steel formwork 405 is fixedly connected to the longitudinal reinforcing ribs 401 and the transverse reinforcing ribs 402, which can strengthen the integrity between the steel formwork 405 and the wall 1 when pouring concrete into the wall 1.
[0027] The steel formwork 405 is equipped with a protective component 5 inside; such as Figure 3 As shown, specifically, the protective component 5 includes an inner cavity 501 disposed inside the steel template 405, a partition 502 welded to the middle position of the inner wall of the inner cavity 501, and several fixing clips 503 fixedly installed on the inner wall of the inner cavity 501 and the outer surface of the partition 502 respectively.
[0028] More specifically, several fixing clips 503 are welded to the inner wall of the inner cavity 501. When installing the air duct 604, the air duct 604 is fixedly installed inside the inner cavity 501 by the fixing clips 503, so as to achieve stable installation of the air duct 604.
[0029] The steel formwork 405 has an installation component 6 installed inside; such as Figure 4 As shown, specifically, the installation component 6 includes an insulated sheet metal plate 601 installed inside the inner cavity 501. The insulated sheet metal plate 601 has a pipe installation groove 602 inside, and an air duct 604 is fixedly installed inside the pipe installation groove 602.
