Problems solved by technology

[0003] As a non-load-bearing wall, the lintel also has to bear the weight from the upper masonry. The existing lintel generally adopts reinforced concrete structure, which is heavy in itself, and has poor thermal insulation and fire protection performance. It is difficult to meet the requirements of the modern construction industry for environmental protection and energy saving. demand for building materials
The existing autoclaved aerated concrete structure is light in weight, has good thermal insulation performance and fire resistance performance, but its bearing capacity is limited, and it is difficult to meet the load requirements of the lintel

Abstract

The invention discloses a high-performance steam-pressure aerated concrete lintel, and relates to the technical field of architectural structures. The high-performance steam-pressure aerated concretelintel comprises a lintel body and at least one piece of truss reinforcing mesh. The lintel body is formed by casting high-performance steam-pressure aerated concrete. The truss reinforcing mesh is arranged in the lintel body and comprises at least two main ribs. A plurality of truss reinforcing steel bars are continuously and fixedly arranged between every two adjacent main ribs in the length direction of the main ribs. A preset included angle is formed between the truss reinforcing steel bars and the main ribs. The high-performance steam-pressure aerated concrete lintel has good thermal insulation and fireproof performance, meanwhile has good structural strength, can bear the loads transmitted by upper building bricks, and has quite high practical use value.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a high-performance autoclaved aerated concrete lintel. Background technique [0002] When door and window openings are set on the wall and the wall opening is larger than 600mm, in order to support various loads transmitted by the masonry above the opening and transfer these loads to the walls on both sides of the opening such as doors and windows, beams are often set on the openings of the doors and windows. This beam is called a lintel. [0003] As a non-load-bearing wall, the lintel also has to bear the weight from the upper masonry. The existing lintel generally adopts reinforced concrete structure, which is heavy in itself, and has poor thermal insulation and fire protection performance. It is difficult to meet the requirements of the modern construction industry for environmental protection and energy saving. demand for building materials. The existing autocla...
