2results about How to "Improve fire protection" patented technology

This utility model relates to the field of steel fire doors and discloses a structure for preventing the installation misalignment of fireproof mortise locks on fire doors. It includes: a fireproof protective cover pre-assembled inside the fire door body; two guide steel plates fixedly installed inside the fireproof protective cover, forming a guide zone between the two guide steel plates; the fireproof protective cover being parallel to the fire door body; a fireproof mortise lock body being inserted between the two guide zones; a side groove on the fire door body; an adapter frame fitted into the side groove; an insertion hole on the adapter frame; and a mating frame fixedly installed on the fireproof mortise lock body. This utility model has the following advantages and effects: it ensures that the fireproof mortise lock body will not misalign during installation, improves installation efficiency, reduces the number of after-sales maintenance visits, lowers labor costs, provides good fire protection in extreme situations such as fires, and improves the safety performance of fire doors.

The application belongs to the technical field of building, and particularly relates to an aluminum veneer roof ridge for replacing a roof lightning strip, comprising a V-shaped roof aluminum framework and a pseudo-classic building roof for mounting the V-shaped roof aluminum framework. The application integrates the lightning strip and the pseudo-classic building roof decoration structure into one by replacing the roof lightning strip with the aluminum veneer roof ridge, which not only facilitates the pseudo-classic building roof pseudo-classic decoration construction, but also improves the aesthetic property of the pseudo-classic building. Moreover, the aluminum veneer roof ridge can effectively reduce the total weight of the building, improve the anti-seismic performance and temperature deformation resistance, and has excellent fireproof function. Meanwhile, the aluminum veneer roof ridge for replacing the roof lightning strip also has the functions of pseudo-classic building roof moisture monitoring and roof drying, which can avoid moss and mildew breeding due to continuous moisture of the pseudo-classic building roof, further avoid the pseudo-classic building roof from being damaged by microorganisms, further avoid the occurrence of water seepage, and improve the reliability of the pseudo-classic building roof.
