technical field

The invention relates to the technical field of floor slab fire protection, and more specifically relates to a heat-resistant and fire-resistant building fire-fighting floor slab.

Background technique

Urban underground spaces or tunnels are usually places where fire prevention measures are relatively weak. There are more and more tall and large spaces in contemporary buildings. In order to maintain a spacious and transparent effect and meet the use requirements, this type of space has broken through the code for the maximum fire protection zone. The regulations on the allowable area, but also correspondingly increase the requirements for fire extinguishing facilities.

In the event of a fire, the floor is the largest fire-affected area and an important structure that can effectively prevent the fire from spreading upstairs. At present, most fire-fighting methods at home and abroad are to install additional fire-fighting facilities, and the effective use of the floor itself has not been considered. This kind of passive fire extinguishing device also requires personnel to actively detect the fire and take fire extinguishing measures in time. If measures are not taken in time and the fire develops rapidly, the fire extinguishing effect will be unsatisfactory.

For this reason, we propose a heat-resistant and fire-resistant building fire-fighting floor to effectively solve some problems existing in the prior art.
