Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof bridge frames, and more specifically, particularly relates to a suspended fireproof bridge frame. Background Art

[0002] Traditional fireproof bridges are mainly composed of fireproof boards composited with glass fiber reinforced materials and inorganic adhesives, metal frames and other fireproof substrates. With fireproof coatings added to the outer layer, the fireproof bridge will not burn when it encounters fire, thereby blocking the spread of fire. It has extremely good fireproof and fire-retardant effects, and is fire-resistant, oil-resistant, corrosion-resistant, non-toxic, and pollution-free. It is easy to install as a whole, has a reasonable structure, a long service life, and is beautiful. The cables are installed in the cable bridge, and the environment is clean and easy to clean. The fireproof coating has the characteristics of thin coating, high fire resistance limit, and strong adhesion. Among them, China Patent No.: CN217984391U discloses a suspended fireproof bridge, including a bridge body, a through groove is opened at the bottom of the inner wall of the bridge body, and a plurality of support bars are opened at equal distances on the inner wall of the through groove. First slide grooves are opened on both sides of the inner wall of the through groove, and a card slot is opened on the inner wall of each support bar. The inner walls of the two first slide grooves are both clamped with protective plates, and sliding buttons are fixed at the two corners at the bottom of the protective plate. The utility model discloses a suspended fireproof bridge frame, which is suspended by means of a latch and a steel cable at its upper end. Equipment to be placed is placed on an internal support bar. During later maintenance, a protective plate is slid out of a first slide groove by a sliding button to expose a through groove at the bottom of the bridge frame body, which is convenient for maintenance by staff. After the maintenance is completed, the protective plate can be closed and clamped in the first slide groove and the clamping slot. It is easy to use and reduces maintenance costs, thereby improving the practicability of the device.

[0003] Based on the above, the inventors found the following problems: the bridge in the above patent can facilitate maintenance by the staff and improve the practicality, but the bridge is installed in sections, and the disassembly method in the above patent is sliding. When the bridge that needs to be repaired is in the middle position, the protective plate is difficult to remove.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a suspended fireproof bridge is provided to achieve a purpose with greater practical value. Utility Model Content
