Fire escape wall pulling bricks
- Description
-
Fire channel wall pull brick is a kind of refractory material with specific structure, which is designed to solve the problem that the stress concentration of the brick is easy to break in the prior art, so as to prevent the serious deformation of the fire channel wall structure. The design feature of this kind of pull brick is that it is in the shape of "work" structure, both ends are cuboid masonry, and the middle is connected by pulling ribs. In the direction of the long side of the masonry, the male and female tenons are arranged respectively on the upper and lower sides, and the joint of the masonry and the tension bar is arranged with a clamping tenon, and the circular arc is excessive. This design not only improves the structural strength, but also prolongs the service life, at the same time saves the production and maintenance cost, and brings good economic benefits for the enterprise
