Description

Technical Field

[0001] This utility model relates to a firewall, specifically a steel rectangular tube firewall body structure, and belongs to the technical field of firewall devices. Background Technology

[0002] The primary function of firewalls is to prevent the spread of fire between zones. Firewalls divide the interior of a building into different fire compartments, effectively preventing the fire from spreading between these compartments during a fire, controlling the fire within a certain area, and reducing fire damage. Firewalls can prevent fire from spreading from one building to another, protecting the safety of adjacent buildings. In the early stages of a fire and during firefighting, firewalls can also effectively confine the fire to a certain space, blocking the fire from spreading from one side of the firewall to the other, buying time for evacuation and firefighting rescue. For some important equipment and facilities, such as fire control rooms, fire extinguishing equipment rooms, and fire pump rooms, firewalls can separate them from other areas, preventing fire from damaging these important facilities and ensuring their normal operation during a fire.

[0003] Most existing firewalls have one of the following structures: First, reinforced concrete columns or beams are poured at appropriate height and width, and polystyrene particle concrete wall panels are installed between the beams and concrete columns. This structure has a long construction time and high cost. Second, depending on the thickness requirements, steel rectangular tubes similar to those used for polystyrene particle concrete wall panels are selected for reinforcement. This solution is faster and cheaper, so most companies choose the second option for polystyrene particle concrete wall panel installation. However, the second solution is not suitable for modern fire protection requirements. Polystyrene particle concrete wall panels can meet the national fire protection rating (more than four hours), while steel rectangular tubes have a fast heat transfer rate and fall far short of the required national fire protection rating. Therefore, we provide a steel rectangular tube firewall structure to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a steel rectangular tube firewall structure, the specific technical solution of which is as follows:

[0005] A steel rectangular tube fireproof wall structure includes a steel rectangular tube frame and fireproof panels. Multiple fireproof panels are installed inside the steel rectangular tube frame and arranged sequentially at equal intervals. The thickness of each fireproof panel is greater than the diameter of the steel rectangular tube frame. A positioning reinforcing bar is inserted through the inner side of the steel rectangular tube frame, with its other end inserted into the interior of the fireproof panel. Fireproof cotton is attached to the outer surface of the steel rectangular tube frame, and self-adhesive mesh fabric is attached to the outer surface of the fireproof cotton.

[0006] Preferably, the fireproof board is elongated, with a groove on one side and a protrusion on the other side, wherein one of the grooves inside the fireproof board contacts a nearby protrusion.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. The steel rectangular tube fire wall structure is relatively easy to construct through the cooperation between the steel rectangular tube frame, fireproof board and fireproof cotton, and the splicing of fireproof boards. It greatly shortens the construction period. The fireproof cotton covers the exposed parts of the steel rectangular tube frame, preventing the fire source from directly contacting the steel rectangular tube frame in the event of a fire, thereby improving the fire resistance rating of the steel rectangular tube frame.

[0009] 2. The fireproof steel rectangular tube fire wall structure utilizes the cooperation between fireproof cotton and self-adhesive mesh fabric. The self-adhesive mesh fabric acts as a shield outside the fireproof cotton, preventing it from falling off the steel rectangular tube frame. The self-adhesive mesh fabric positions the fireproof cotton, ensuring that it is always wrapped around the steel rectangular tube frame, thus improving the stability of the fireproof cotton.

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] Please see Figures 1-5A steel rectangular tube fire wall structure includes a steel rectangular tube frame 1 and multiple fireproof panels 2. The fireproof panels 2 are made of polystyrene particle concrete, which has good fire resistance and high-temperature resistance. Multiple fireproof panels 2 are installed inside the steel rectangular tube frame 1, arranged sequentially at equal intervals. The thickness of the fireproof panels 2 is greater than the diameter of the steel rectangular tube frame 1. After the steel rectangular tube frame 1 is welded and fixed, a layer of fire-retardant coating is applied to its surface to improve its fire resistance and high-temperature resistance. During installation, the fireproof panels 2 must be tightly fitted to the steel rectangular tube frame 1 without gaps, and the steel rectangular tube frame 1 must be positioned in the center of the fireproof panels 2. The fireproof panels 2 are fixed together with adhesive mortar. Fireproof cotton 6 is connected to the outer surface of the steel rectangular tube frame 1, and self-adhesive mesh cloth 7 is connected to the outer surface of the fireproof cotton 6. After the entire wall is installed, the exposed steel rectangular tube frame 1 is treated with fireproofing and fire resistance. First, fireproof cotton 6 is pasted onto the rectangular tube, and no part of the steel rectangular tube frame 1 should be exposed. Then, the fireproof cotton 6 is fixed with self-adhesive mesh cloth 7. Finally, 2-3mm of adhesive fire-resistant material is applied to the mesh cloth. A positioning steel bar 3 is inserted through the inner side of the steel rectangular tube frame 1. The other end of the positioning steel bar 3 is inserted into the fireproof board 2. The positioning steel bar 3 connects the steel rectangular tube frame 1 and the fireproof board 2 together, so that the steel rectangular tube frame 1 and the fireproof board 2 form a whole, improving the overall strength of the fireproof board 2 and the steel rectangular tube frame 1.

[0018] The fireproof board 2 is long and narrow. A groove 4 is provided on one side of the fireproof board 2, and a protrusion 5 is connected to the other side of the fireproof board 2. The groove 4 inside one of the fireproof boards 2 contacts the protrusion 5 of the adjacent fireproof board 2. The groove 4 wraps around the protrusion 5, which makes the fireproof board 2 stable when connected. The groove 4 and the protrusion 5 make the connection between the fireproof boards 2 tighter. After multiple fireproof boards 2 are connected together, the connection strength between the fireproof boards 2 is increased.

[0019] In use, the following steps are taken: First, connect the steel rectangular tube frame 1 to the building. Then, apply fireproof coating to the surface of the steel rectangular tube frame 1. Next, install the fireproof board 2 inside the steel rectangular tube frame 1. When installing the fireproof board 2, adhere one side of the groove 4 to one side of the protrusion 5 with adhesive mortar. Then, push one side of the protrusion 5 into the groove 4. Then, insert the positioning steel bar 3 into the steel rectangular tube frame 1 and the fireproof board 2. Then, adhere the fireproof cotton 6 to the surface of the steel rectangular tube frame 1. Then, adhere the self-adhesive mesh cloth 7 to the outside of the fireproof cotton 6 and the fireproof board 2. Apply a gel-like fire-resistant material to the outside of the self-adhesive mesh cloth 7.
