Description

Technical Field

[0001] The utility model relates to the technical field of steel structure building construction, in particular to a fire protection device for building steel structure nodes. Background Art

[0002] The nodes in building steel structures are the key parts connecting various structural components. They not only undertake the function of transmitting force between structural members, but also ensure the stability, safety and durability of the structure. In building steel structures, fire protection of nodes is very important. It is necessary to maintain sufficient fire resistance when a fire occurs to ensure the safety and stability of the structure. Therefore, fire protection devices for building steel structure nodes were born to achieve the best fire protection effect and economy.

[0003] Traditional fire protection devices for building steel structure nodes are composed of protective sleeves, fire-retardant coatings and other parts. When a fire occurs, the materials in the fire-retardant coating will expand and foam, forming a heat insulation effect, reducing the speed of heat conduction to the steel structure. This can extend the fire resistance time of the steel structure and maintain the strength and stability of the structure for a certain period of time.

[0033] In the process of implementing the fire protection measures for the steel beam, when preparing to install the fire protection cover 6, the staff needs to carefully insert the fire protection cover 6 into the two side walls of the steel beam 2 to ensure that the mounting plate 5 can be completely fitted to the connecting plate 3. Next, the operator needs to place the mounting shell 8 into the interior of the mounting plate 5 so that the mounting column 14 can slide smoothly into the card slot 16. At this time, by manually rotating the rotating handle 9, the operator can realize the rotation of the mounting column 14 so that the card block 15 can be restored to its original state. Subsequently, since the spring 12 is no longer squeezed by external force, it will naturally return to its original state, pushing the mounting column 14 to move downward, and then sliding the card block 15 into the card slot 16. At this time, operate the rotating handle 9 again to ensure that the card block 15 is firmly stuck in the card slot 16, indicating that the installation of the fire protection cover 6 is completed. When the fire protection cover 6 needs to be maintained or replaced, the operator The operator first needs to rotate the rotating handle 9 to rotate the mounting column 14, so that the block 15 can also rotate accordingly.

As the rotating handle 9 continues to be pulled up, when it reaches the appropriate position of the internal cavity of the mounting shell 8, the operator rotates the rotating handle 9 again, so that the mounting column 14 rotates inside the rotating column 11, driving the block 15 to rotate into the cavity and make it stuck in the cavity. At this time, the mounting shell 8 can be safely removed, and then the fire protection cover 6 can be easily separated from the steel beam 2 to complete the replacement of the fire protection cover 6.

The side wall of the fireproof sealing layer 18 is provided with a supporting structure layer 19. The supporting structure layer 19 is made of steel and concrete.

The side wall of the fireproof filling layer 20 is provided with a fireproof coating layer 21. The fireproof coating layer 21 is made of rock wool board. The side wall of the fireproof coating layer 21 is provided with a fireproof partition layer 22. The fireproof partition layer 22 is made of glass fiber.

[0035] The protective layer 17 is carefully prepared using silicate paint, which is well-known for its excellent fireproof properties. When a fire occurs, it can effectively reduce the damage of the fire to the building structure, thereby buying precious time for personnel evacuation and fire fighting. The fireproof sealing layer 18 is a composite of silicone and polyurethane synthetic materials. The silicone material not only has excellent sealing and bonding capabilities, but can also be widely used in various joints and cracks in closed buildings to prevent the spread of fire. The polyurethane material can be used as an insulating material inside and outside the building, effectively reducing the transfer of heat and sound energy, and further improving the safety of the building. The supporting structure layer 19 is composed of hard steel and solid concrete. The high strength and rigidity of the steel enable it to bear huge loads while maintaining a small cross-sectional size, thereby realizing a lightweight design of the building and greatly improving the structural efficiency of the building.

[0036] Working principle: When using the device to install the fire protection cover 6, first put the fire protection cover 6 into the side wall of the steel beam 2, so that the installation plate 5 fits the connecting plate 3, and then put the installation shell 8 into the installation plate 5, so that the installation column 14 slides into the card slot 16. At this time, by turning the rotating handle 9, the installation column 14 is rotated to allow the block 15 to recover. Subsequently, the spring 12 loses its extrusion and recovers, pushing the installation column 14 down, so that the block 15 slides into the card slot 16. At this time, by turning the rotating handle 9, the block 15 is stuck in the card slot 16. At this time, the installation of the fire protection cover 6 is completed. When the fire protection cover 6 needs to be removed, first turn the rotating handle 9 to allow the installation column 14 rotates, causing the card block 15 to rotate, and then the rotating handle 9 is pulled up to drive the rotating column 11 to move up, thereby moving the fixed block 13 up, allowing the spring 12 to be squeezed and contracted, so that the installation column 14 moves up, allowing the card block 15 to escape from the inside of the card slot 16 and enter the inside of the installation shell 8. As the rotating handle 9 is pulled up, when it is pulled up to the upper position of the internal cavity of the installation shell 8, the rotating handle 9 is rotated to make the installation column 14 rotate inside the rotating column 11, driving the position of the card block 15 to rotate, thereby causing the card block 15 to be stuck in the cavity. At this time, the installation shell 8 can be taken out, and then the fire protection cover 6 is separated and replaced. The protective layer 17 is made of silicate paint. Silicate coatings have excellent fireproof properties and can effectively delay the impact of fire on building structures. The fireproof sealing layer 18 is made of silicone and polyurethane. Silicone has excellent sealing and bonding properties and can be used to seal joints and cracks in buildings. Polyurethane can be used as an insulating material inside and outside the building, which can effectively reduce the conduction of heat and sound. The supporting structure layer 19 is made of steel and concrete. Steel has high strength and rigidity and can withstand large loads with smaller cross-sectional dimensions, thereby realizing the lightweight design of the building. Concrete is often used as a filling material or supporting element of steel structures to increase the bearing capacity and stability of the columns. The fireproof filling layer 20 is made of expanded perlite, which has good fire resistance and can effectively prevent the spread of flames and heat, thereby improving the fire safety of the building. The fireproof coating layer 21 is made of rock wool board, which has good thermal insulation properties due to its unique fiber structure and density. It can effectively reduce the conduction and loss of heat, improve the energy efficiency of buildings, and at the same time has a certain degree of flexibility and elasticity, can buffer and reduce the vibration of the building structure during an earthquake, and improve the earthquake resistance of the building. The fireproof partition layer 22 is made of glass fiber, which can still maintain good performance at high temperatures and is not easy to soften or deform. Compared with some synthetic fibers, glass fiber is more environmentally friendly because it is made of renewable natural resources and can be recycled.
