Description

A fireproof sealing structure for building openings Technical Field

[0001] This utility model belongs to the field of building fire protection technology, and in particular, it is a fireproof sealing structure for building openings. Background Technology

[0002] In construction projects, various pipes and cables create numerous openings when passing through walls and floors. If these openings are not effectively fireproofed, flames and high-temperature smoke can spread rapidly through them during a fire, causing the fire to spread quickly within the building, seriously threatening lives and causing significant property damage. Traditional fireproofing structures (such as metal frames and rigid fireproof boards) directly compress the walls using bolts and pressure plates, which can lead to wall cracks, plaster peeling, and even damage to the internal steel reinforcement or masonry structure, affecting the building's aesthetics and maintenance costs.

[0003] A search revealed a Chinese patent document (authorization announcement number CN218493109U). This application discloses a sealing structure for holes in building formwork. By fixing a spring between the first and second grooves, the spring is stretched, and its tension reacts on the fixing plate, thereby making the fixing plate and the elastic sealing plate more stably adhere to the building formwork. This prevents concrete from entering between the elastic sealing plate and the building formwork during pouring, which would make it difficult to disassemble the sealing structure later. This device can meet basic usage requirements. However, sealing structures (such as metal frames or rigid fireproof boards) directly squeeze the wall through bolts, pressure plates, etc., which may cause wall cracks, plaster layer peeling off, or even damage the internal steel bars or masonry structure of the wall, affecting the building's aesthetics and maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide a fireproof sealing structure for building openings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fireproof sealing structure for building openings, comprising a building wall, wherein a buffer box is provided on the side of the building wall;

[0006] The buffer box has four U-shaped grooves symmetrically arranged on its outer periphery for sliding. The buffer box is connected to a compression spring for cushioning. The end of the compression spring away from the building wall is connected to a movable plate. The movable plate is slidably disposed inside the buffer box. Four guide posts for restricting the movement of the movable plate are welded to the outer periphery of the movable plate. The four guide posts are slidably disposed inside the U-shaped grooves. A stop post is welded to the side of the movable plate away from the compression spring.

[0007] Preferably, the buffer box has a threaded rod slidably disposed inside, and a protective gasket is disposed on the outer periphery of the threaded rod.

[0008] Preferably, the outer circumference of the threaded rod is rotatably connected to an adjusting threaded block, and the end of the threaded rod is equipped with a limit groove.

[0009] Preferably, a connecting rod is welded to one end of the threaded rod near the building wall, and two connecting blocks for support are welded to the end of the connecting rod. Each of the two connecting blocks has a circular groove for guidance inside.

[0010] Preferably, a rotating shaft is rotatably connected inside the circular groove, and a spring is connected inside the circular groove, with one end of the spring connected to the outer periphery of the rotating shaft.

[0011] Preferably, a locking rod for contacting the building wall is installed on the outer periphery of the rotating shaft.

[0012] Preferably, the connecting rod and the connecting block are slidably disposed inside the hole.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This fireproof sealing structure for building openings benefits from the structure of the buffer box. By rotating the adjusting threaded block, the adjusting threaded block moves closer to the washer on the threaded rod. Finally, the adjusting threaded block drives the washer to press against the abutment column. The abutment column drives the moving plate and the buffer box to press against the other side of the building wall. The locking rod drives the buffer box to be fixed to the side of the building wall. The buffer box seals the building opening. Compared with the traditional fireproof sealing structure for building openings that directly presses against the wall, this structure improves the buffering capacity, prevents wall cracking and plaster layer peeling, reduces damage to the internal steel bars or masonry structure of the wall, and ensures the building's aesthetics and maintenance costs.

[0015] This fireproof sealing structure for building openings benefits from the locking rod mechanism. When the locking rod is rotated, it causes the rotating shaft to rotate at a certain angle, which in turn causes the spring to deform. The locking rod and connecting rod then enter the opening. When the locking rod leaves the opening, the spring causes the rotating shaft and locking rod to return to their original positions, and the outer side of the locking rod contacts the side of the building wall. This structure allows for easy disassembly and saves operation time. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] As shown in Figures 1 to 5, a fireproof sealing structure for building openings includes a building wall 1, a buffer box 2 installed on the side of the building wall 1, and a fiber-reinforced silicate fireproof board installed on the side of the buffer box 2. The board is made of silicate and calcareous materials as the base material, mixed with fibers (such as glass fiber and cellulose) and pressed. The fire resistance limit can reach 2-4 hours, the temperature resistance is above 1000℃, and it burns without smoke or toxicity.

[0027] The buffer box 2 has four U-shaped grooves 201 symmetrically arranged on its outer periphery for sliding. A compression spring 202 for cushioning is connected inside the buffer box 2. Damping is provided between the compression spring 202 and the buffer box 2. The main function of the damping is to improve the reliability and durability of the fireproof sealing structure by consuming vibration energy, suppressing impact loads, and optimizing dynamic response. A movable plate 203 is connected to the end of the compression spring 202 away from the building wall 1. The movable plate 203 is slidably disposed inside the buffer box 2. Four grooves are welded to the outer periphery of the movable plate 203 to limit its movement. The four guide pillars 204 are slidably set inside the U-shaped groove 201. The moving plate 203 is welded with a stop pillar 205 on the side away from the compression spring 202. The adjusting threaded block 207 is rotated and moves closer to the washer 206 on the threaded rod 208. Finally, the adjusting threaded block 207 drives the washer 206 to squeeze the stop pillar 205. The stop pillar 205 drives the moving plate 203 and the buffer box 2 to squeeze the other side of the building wall 1. The locking rod 305 drives the buffer box 2 to be fixed on the side of the building wall 1. The buffer box 2 seals the building hole.

[0028] The buffer box 2 has a threaded rod 208 that slides inside. A protective gasket 206 is provided on the outer periphery of the threaded rod 208. An adjusting threaded block 207 is rotatably connected to the outer periphery of the threaded rod 208. A limit groove is installed at the end of the threaded rod 208 to prevent the adjusting threaded block 207 from falling off.

[0029] A connecting rod 3 is welded to one end of the threaded rod 208 near the building wall 1. The connecting rod 3 and the connecting block 301 are slidably disposed inside the hole 101. Two supporting connecting blocks 301 are welded to the end of the connecting rod 3. Each of the two connecting blocks 301 has a circular groove 302 for guidance. A rotating shaft 303 is rotatably connected inside the circular groove 302. A spring 304 is connected inside the circular groove 302. The spring 304 stores elastic potential energy by winding, and provides power to drive mechanical operation or realize component reset when released. One end of the spring 304 is connected to the rotating shaft 301. The outer periphery of the shaft 303 is connected to the building wall 1. A locking rod 305 is installed on the outer periphery of the shaft 303 for contacting the building wall 1. When the locking rod 305 is rotated, the shaft 303 is rotated at a certain angle. The spring 304 is deformed. The locking rod 305 and the connecting rod 3 enter the hole 101. When the locking rod 305 leaves the hole 101, the spring 304 drives the shaft 303 and the locking rod 305 to return to their original positions. The outer side of the locking rod 305 contacts the side of the building wall 1. Due to the deformation of the compression spring 202, there is a certain elastic buffer, thereby protecting the structure and the building wall 1 from damage.

[0030] Working principle

[0031] This fireproof sealing structure for building openings operates as follows: First, the locking rod 305 is rotated, causing the rotating shaft 303 to rotate at a certain angle. The spring 304 deforms, and the locking rod 305 and connecting rod 3 enter the opening 101. Then, the locking rod 305 leaves the opening 101, and the spring 304 causes the rotating shaft 303 and locking rod 305 to return to their original positions. The outer side of the locking rod 305 contacts the side of the building wall 1. Rotating the adjusting screw block 207 adjusts the screw... The threaded block 207 moves closer to the washer 206 on the threaded rod 208. Finally, the threaded block 207 adjusts the washer 206 to press the abutment 205. The abutment 205 drives the moving plate 203 and the buffer box 2 to press the other side of the building wall 1. The locking rod 305 drives the buffer box 2 to be fixed to the side of the building wall 1. The buffer box 2 seals the building hole. Due to the deformation of the compression spring 202, there is a certain elastic buffer, thereby protecting the structure and building wall 1 from damage.
