[0002] At present, for fireproof brick walls with steel beams on top, the conventional fireproof sealing method at the intersection is mainly to build to the bottom of the steel beam with a certain gap and fill the gap with fine stone concrete, fireproof mortar or fireproof mud. Because it is between two different materials, brick wall and steel structure, it is difficult to fill the gap effectively and fully. Moreover, over time, the brick wall itself will settle and the sealing material will shrink, which will easily cause gaps, fail to meet the fireproof sealing requirements, and cause fire hazards.

[0003] To this end, we have developed a fire-proof blocking component between steel beams and brick walls to solve the above problems. Utility Model Content
