Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building tools, and particularly relates to a self-assembly lintel structure for building doors and windows. BACKGROUND

[0002] Doors and windows are divided into envelope components or partition components according to their positions, have different design requirements, and have functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fireproofing. New requirements are energy saving. In cold regions, heat loss through door and window gaps accounts for about 25% of total heating heat consumption. The requirement for the airtightness of doors and windows is an important content in energy-saving design. Doors and windows are important components of building envelope systems. In the prior art, in order to improve the airtightness, a beam body is pre-buried on the underside of the door and window during installation, but the existing beam body has the following problems during use:

[0003] 1. The beam body is a prefabricated integral type, and some relatively long integral beam bodies are inconvenient to transport and carry. When a collision occurs, the beam body is prone to breakage or cracking. When a plurality of short beam bodies are used for butt joint installation, the plurality of beam bodies cannot maintain flatness, resulting in gaps during the later installation of doors and windows.

[0004] 2. After the beam body is pre-buried, the pre-buried door and window frame body and the beam body are connected by bolts. Grouting or glue injection is performed in the gap between the beam body and the door and window frame body, but cracking is prone to occur later, resulting in poor waterproofness and water ingress in the gaps.
