Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically a fixing structure for exterior wall window openings. Background Technology
[0002] Autoclaved aerated concrete (AAC) partition walls offer advantages such as lightweight construction, excellent fire resistance and sound insulation, environmental friendliness, economy, and ease of construction. Made primarily from silica sand, cement, and lime, and reinforced with rust-proofed steel bars, these porous concrete products are cured under high temperature, high pressure, and steam. They possess excellent sound insulation and absorption properties, as well as good thermal insulation. With a specific gravity of only 0.5, which is one-quarter that of ordinary concrete, they significantly reduce the self-weight of the walls and lower the cost of building foundations. Products include partition walls, interior wall panels, floor slabs, and roof panels.
[0003] In current construction projects, lightweight partition walls commonly suffer from insufficient wind load resistance during the construction phase. When the wall is subjected to concentrated stress around door and window openings or encounters strong winds, structural damage such as cracking of board joints and peeling at the joints often occurs. In severe cases, it may lead to functional defects such as deformation of door and window frames and peeling off of wall finishes. Utility Model Content
[0004] The purpose of this utility model is to provide a fixing structure for window openings in exterior walls, which aims to solve the problem of insufficient wind load resistance of lightweight partition boards during the construction stage in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: the external wall window opening fixing structure includes partition wall panels fixedly installed relative to the main beam and shear wall, the partition wall panels including a left partition wall panel for fixing to the left shear wall, a right partition wall panel for fixing to the right shear wall, and a lower partition wall panel for fixing to the lower main beam;
[0006] The upper main beam, lower partition wall, left partition wall, and right partition wall form a window opening;
[0007] A left reinforcement member extending vertically and waterproofly is fixedly installed between the left partition wall and the upper and lower main beams;
[0008] A right reinforcement member extending in the vertical direction is fixedly installed between the right partition wall and the upper and lower main beams;
[0009] A transverse reinforcement is fixedly installed between the lower partition wall and the left and right reinforcement components.
[0010] Preferably, the upper and lower ends of the left and right reinforcing members are fixedly connected to the upper and lower main beams via the first connecting member.
[0011] Preferably, the first connector includes an embedded plate;
[0012] The lengths of the left and right reinforcement members are both longer than the partition wall, so that the embedded plate is fixed at the upper and lower ends of the left and right reinforcement members, and the other side of the embedded plate is fixedly connected to the upper and lower main beams.
[0013] Preferably, the left and right reinforcement components are fixedly connected to the partition wall panel by a first hook bolt.
[0014] Preferably, the transverse reinforcement is fixedly connected to the partition wall panel by a second hook bolt.
[0015] Preferably, the door and window components include doors, windows, and railings;
[0016] An S-shaped connector is fixed to the horizontal reinforcement member, and the doors, windows and railings are installed on the S-shaped connector.
[0017] The railing is located on the outside of the doors and windows.
[0018] Preferably, a sealant is applied between the door / window and the window opening structure.
[0019] The beneficial effects are: 1. After the partition wall panels are installed, to further enhance the connection strength between the partition wall system and the main building structure, it is necessary to install the left and right reinforcement components, as well as the horizontal reinforcement components, in sequence. The implementation of this multi-directional reinforcement system can significantly improve the structural stability between the partition wall panels and the main beams, effectively prevent the panels from shifting or loosening, thereby ensuring the overall robustness and long-term safety of the partition wall system.
[0020] 2. The pre-embedded plate allows the left and right reinforcement components to be installed between two adjacent main beams. Then, the left and right reinforcement components are installed to the partition wall using the first hook bolt, which improves the ease of installation of the left and right reinforcement components. Moreover, the horizontal reinforcement components are fixed between the left and right reinforcement components and then installed on the partition wall using the second hook bolt, making the overall installation convenient and avoiding the waste of a lot of manpower and material resources.
