Problems solved by technology

However, it is found in the construction that the cast-in-place reinforced concrete lintel uses more lintel steel bars and cement, and the construction period is relatively long, the maintenance of masonry is troublesome, and it is easy to crack, which poses a potential threat to future housing; Concrete lintels not only have the problem of relatively large amount of steel bars and cement used in the lintel, but also the weight of the finished product is relatively large, which brings great trouble to the site construction. At the same time, the existing lintels do not take into account the routing of power lines inside the house The problem of wires caused the user to use a power drill to open a channel on the wall to facilitate the routing of the wires inside and outside the house in the later stage of house decoration. This is not only time-consuming and laborious, but also greatly increases labor costs. cost

Abstract

The invention discloses an autoclaved aerated concrete lintel which has a cuboid-shaped brick body structure and is characterized in that a plurality of parallel grooves are formed in the upper surface of the brick body structure and along the long edge of the brick body structure; a circular countersinks are formed in the bottom surface at the two ends of each groove; a reinforcing rib is preburied in each groove, is a steel bar and has a C-shaped structure; edgefolds are arranged at the two ends of each reinforcing rib and matched with the corresponding countersinks; and wiring channels are formed in the brick body structure along the long edge and / or the short edge of the brick body structure. The autoclaved aerated concrete lintel is small in density, large in strength and convenient in construction and installation. By forming the wiring channels in the brick body structure in the long edge and / or the short edge direction, the autoclaved aerated concrete lintel is convenient in the installation layout of lines during house decoration in the future, saves the time, the labor and the construction cost and is beautiful and convenient.

Description

technical field [0001] The invention relates to a lintel for doors and windows in buildings, in particular to an autoclaved aerated concrete lintel. Background technique [0002] At present, the lintels above the doors and windows of houses generally adopt cast-in-place reinforced concrete lintels or prefabricated reinforced concrete lintels. However, it is found in the construction that the cast-in-place reinforced concrete lintel uses more lintel steel bars and cement, and the construction period is relatively long, the maintenance of masonry is troublesome, and it is easy to crack, which poses a potential threat to future housing; Concrete lintels not only have the problem of relatively large amount of steel bars and cement used in the lintel, but also the weight of the finished product is relatively large, which brings great trouble to the site construction. At the same time, the existing lintels do not take into account the routing of power lines inside the house The p...
