Description
A connector for constructing a lightweight pressure relief wall in a chemical plant. Technical Field
[0001] This utility model belongs to the field of lightweight pressure relief walls, and in particular relates to a connector for the construction of lightweight pressure relief walls in chemical plant buildings. Background Technology
[0002] Chemical plant buildings are industrial buildings used for the production, processing, storage, and transportation of chemical products and related materials. Due to the involvement of flammable, explosive, toxic, and corrosive substances, the design, construction, and operation of chemical plant buildings must strictly adhere to safety standards and regulations to ensure the safety of personnel and the environment. Pressure relief wall panels are mainly used to release the pressure generated by an explosion in a pre-set manner when an explosion occurs inside the building, thereby protecting the main structure of the building and the safety of personnel. The design goal of pressure relief wall panels is to break or separate quickly to prevent greater structural damage. Connectors are required for connection during the installation of pressure relief walls.
[0003] In current applications of pressure relief walls, self-tapping screws, expansion bolts, and angle steel are generally used for connection. After a pressure relief wall panel breaks, the broken panel can usually be repaired by quick replacement, resulting in low maintenance costs. However, the force required to fix the pressure relief wall with self-tapping screws, expansion bolts, and angle steel is relatively small, and it is easy to fall off when subjected to a large impact. Furthermore, it is inconvenient to replace the wall when damage occurs at points other than the break. Summary of the Invention
[0004] In view of this, the present invention aims to provide a connector for the construction of a lightweight pressure relief wall in a chemical plant, in order to solve at least one of the technical problems in the background art. This application facilitates the quick and easy connection of single-layer and double-layer pressure relief wall panels through its connection structure, and can withstand greater impact forces, while also facilitating later replacement.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A connector for constructing a lightweight pressure relief wall in a chemical plant, wherein a keel support is provided between a double-layer pressure relief wall panel and a single-layer pressure relief wall panel; the single-layer pressure relief wall panel is connected to the keel support through a first connecting structure, and the double-layer pressure relief wall panel is connected to the keel support through a second connecting structure;
[0007] Both the first and second connection structures include a sleeve assembly, a mounting assembly, and a collar assembly. The mounting assembly is threaded inside the sleeve assembly, and the collar assembly is located outside the sleeve assembly.
[0008] The sleeve assembly of the first connection structure passes through the single-layer pressure relief wall panel and the keel support, while the collar assembly and the installation assembly fix the single-layer pressure relief wall panel and the keel support.
[0009] The sleeve assembly of the second connection structure passes through the double-layer pressure relief wall panel and the keel support, while the collar assembly and the installation assembly fix the single-layer pressure relief wall panel and the keel support.
[0010] Furthermore, the end of the mounting component of the first connecting structure is fixed by a limiting nut;
[0011] The end of the mounting component of the first connection structure is fixed by connecting bolts.
[0012] Furthermore, the mounting components include a threaded rod, a hexagonal seat, and a cylindrical platform;
[0013] One end of the threaded rod is connected to the hexagonal base, and the cylindrical platform is set on the hexagonal base.
[0014] Furthermore, a reinforcing rhombus is provided on the cylindrical platform.
[0015] Furthermore, the outer wall of the threaded rod is provided with an external thread corresponding to the sleeve assembly;
[0016] The end of the threaded rod away from the hexagonal seat has a threaded hole corresponding to the connecting bolt.
[0017] Furthermore, the sleeve assembly includes a base and a threaded sleeve. The base is disposed at the end of the threaded sleeve, and the threaded sleeve has an internal thread corresponding to the external thread of the threaded rod.
[0018] Furthermore, the threaded sleeve is provided with a pressure-bearing surface for installing the collar assembly.
[0019] Furthermore, the collar assembly includes a collar and a limiting bolt. The collar is sleeved on the outside of the threaded sleeve, and the collar abuts against the pressure surface of the threaded sleeve through the limiting bolt.
[0020] Furthermore, the number of the first connection structures is at least four.
[0021] Furthermore, the number of second connection structures is at least four.
[0022] A connector for constructing a lightweight pressure relief wall in a chemical plant.
[0023] Compared with existing technologies, the connector for constructing a lightweight pressure relief wall in a chemical plant, as described in this utility model, has the following advantages:
[0024] 1. When the pressure relief wall needs to be replaced, the connection parts used in the construction of the lightweight pressure relief wall in the chemical plant of this application can be removed by removing the limit nut and the connecting bolt, and then rotating the hexagonal seat to pull the connecting bolt out of the threaded sleeve, which is convenient for disassembly. When damage occurs at non-explosion relief points, it is convenient for disassembly and replacement, thus improving work efficiency.
[0025] 2. In this application, when subjected to a large impact force, the hexagonal seat and collar are attached to the surface of the single-layer pressure relief wall panel, the double-layer pressure relief wall panel and the keel support. Compared with the connection of self-tapping screws, expansion bolts and angle steel, the force-bearing surface is larger and the pressure is smaller, thereby improving the strength of the connection. The probability of falling off under a large impact is reduced, and the service life of the equipment is improved.
[0026] 3. When installing the double-layer pressure relief wall panel in this application, the limiting bolt is rotated in the reverse direction to pull the base to the front end, and then the limiting bolt is rotated in the forward direction to make the end of the limiting bolt fit against the upper surface of the pressure-bearing surface to fix the threaded sleeve, which facilitates the connection of pressure relief walls of different thicknesses.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0038] Referring to Figures 1-4, one embodiment of this utility model is provided: a connector for the construction of a lightweight pressure relief wall in a chemical plant, including a keel support 1. The front end of the keel support 1 is provided with a single-layer pressure relief wall panel 3, and the rear end of the keel support 1 is provided with a double-layer pressure relief wall panel 4. The front inner wall and the rear inner wall of the keel support 1 are provided with four first connecting structures 2 and four second connecting structures 5 arranged in a rectangular pattern. The first connecting structures 2 and the second connecting structures 5 facilitate quick connection between the single-layer pressure relief wall panel 3 and the double-layer pressure relief wall panel 4, and can withstand greater impact force, and is also convenient for later replacement.
[0039] The first connecting structure 2 and the second connecting structure 5 have a total of eight collars 201. The eight collars 201 are respectively set on the front inner wall and the rear inner wall of the keel support 1. The rear end face of the four collars 201 at the front and the front end face of the four collars 201 at the rear are provided with bases 203. The center of the front end face of the four bases 203 at the front and the center of the rear end face of the four bases 203 at the rear are fixedly connected with threaded sleeves 204. The four threaded sleeves 204 at the front pass through the front inner wall of the keel support 1 and the rear end face of the single-layer pressure relief wall panel 3 in sequence and lead to the front end face of the single-layer pressure relief wall panel 3. The four threaded sleeves 204 at the rear pass through the rear inner wall of the keel support 1 and the front end face of the double-layer pressure relief wall panel 4 in sequence and lead to the interior of the double-layer pressure relief wall panel 4.
[0040] Hexagonal seats 206 are provided on the front surface of the single-layer pressure relief wall plate 3 at the front of the four threaded sleeves 204 and the rear surface of the double-layer pressure relief wall plate 4 at the rear of the four threaded sleeves 204.
[0041] Threaded rods 210 are fixedly connected to the center of the rear end face of the four hexagonal bases 206 at the front and the center of the front end face of the four hexagonal bases 206 at the rear. The four threaded rods 210 at the front are threaded through the four threaded sleeves 204 at the front and extend to the rear end of the four threaded sleeves 204, and each end is threaded with a connecting bolt 211. The four threaded rods 210 at the rear pass through the rear end face of the double-layer pressure relief wall plate 4, and each end is threaded into the interior of the four threaded sleeves 204 at the rear. By connecting the rear end of the base 203... The threaded sleeve 204 passes through the collar 201, the keel bracket 1, and the double-layer pressure relief wall panel 4. Then, the threaded rod 210 passes through the double-layer pressure relief wall panel 4 and is threaded into the inside of the threaded sleeve 204. By first passing the threaded sleeve 204 at the front end of the base 203 through the collar 201, the keel bracket 1, and the single-layer pressure relief wall panel 3, and then threading the threaded rod 210 through the threaded sleeve 204, and then using the limit nut 209 to thread it onto the outside of the threaded rod 210 at the rear end of the base 203, it is convenient to install the single-layer pressure relief wall panel 3.
[0042] As shown in Figures 3 and 4, each of the eight collars 201 has a limiting bolt 202 at the center of its upper end face, and each of the eight threaded sleeves 204 has a pressure-bearing surface 205 at the center of its upper end face. The lower ends of the eight threaded sleeves 204 pass through the upper end faces of the eight collars 201 and extend into the interior of the collars 201, with their ends respectively attached to the upper end faces of the eight pressure-bearing surfaces 205. By rotating the limiting bolt 202 in the reverse direction, the base 203 is pulled towards the front end. Then, by rotating the limiting bolt 202 in the forward direction, the end of the limiting bolt 202 is attached to the upper surface of the pressure-bearing surface 205 to fix the threaded sleeve 204, which facilitates length adjustment.
[0043] A cylindrical platform 207 is fixedly connected to the center of the front face of the four hexagonal bases 206 at the front and the center of the rear face of the four hexagonal bases 206 at the rear. A reinforcing ridge 208 is fixedly connected to the center of the front face of the four cylindrical platforms 207 at the front and the center of the rear face of the four cylindrical platforms 207 at the rear. The cylindrical platforms 207 and the reinforcing ridge 208 reinforce the hexagonal bases 206, thereby improving the overall strength of the hexagonal bases 206.
[0044] Threaded holes 212 are provided at the center of the rear end face of the four threaded rods 210 at the front end and at the center of the front end face of the four threaded rods 210 at the rear end. Connecting bolts 211 are provided at the front end face of the four bases 203 at the rear end. The four connecting bolts 211 pass through the front end of the four bases 203 at the rear end and pass into the four threaded sleeves 204. The ends are threaded into the four threaded holes 212 at the rear end. After the connecting bolts 211 are passed through the bases 203 at the rear end, they are threaded into the threaded holes 212, which facilitates the installation of the double-layer pressure relief wall panel 4.
[0045] Working principle: When installing the single-layer pressure relief wall panel 3, the threaded sleeve 204 at the front end of the base 203 is first passed through the collar 201, the keel bracket 1 and the single-layer pressure relief wall panel 3, and then the threaded rod 210 is threaded through the threaded sleeve 204. The threaded sleeve 204 is provided with an internal thread corresponding to the external thread of the threaded rod 210.
[0046] Then, the limiting nut 209 is threaded onto the outside of the threaded rod 210 at the rear end of the base 203, which facilitates the installation of the single-layer pressure relief wall panel 3. When installing the double-layer pressure relief wall panel 4, the limiting bolt 202 is rotated in the reverse direction to pull the base 203 towards the front end, and then the limiting bolt 202 is rotated in the forward direction so that the end of the limiting bolt 202 is attached to the upper surface of the pressure-bearing surface 205 to fix the threaded sleeve 204. The threaded sleeve 204 at the rear end of the base 203 is passed through the collar 201, the keel bracket 1 and the double-layer pressure relief wall panel 4. Then, the threaded rod 210 is passed through the double-layer pressure relief wall panel 4 and threaded into the inside of the threaded sleeve 204. Then, the connecting bolt 211 is passed through the base 203 at the rear and threaded into the inside of the threaded hole 212, which facilitates the installation of the double-layer pressure relief wall panel 4 and facilitates the connection of pressure relief walls of different thicknesses.
[0047] When subjected to significant impact, the hexagonal base 206 and collar 201 adhere to the surface of the single-layer pressure relief wall panel 3, the double-layer pressure relief wall panel 4, and the keel support 1. Compared with the connection of self-tapping screws, expansion bolts, and angle steel, the force-bearing surface is larger and the pressure is smaller, thereby improving the strength of the connection. The probability of detachment under significant impact is reduced, thus improving the service life of the equipment.
[0048] When replacement is needed, the limit nut 209 and the connecting bolt 211 are removed, and then the hexagonal seat 206 is rotated to unscrew the connecting bolt 211 from the threaded sleeve 204, which facilitates disassembly. When damage occurs at a non-explosion relief point, it is easy to disassemble and replace, thus improving work efficiency.
[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
