Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure building technology, and in particular to a reinforcement device for door and window openings in ALC panel walls. Background Technology
[0002] With the rise of prefabricated construction, steel structure buildings, using steel beams and columns as main components and assembled on-site to form the main structure, naturally possess the characteristics of prefabricated construction and have received increasing attention. In these buildings, the enclosure system typically uses prefabricated wall panels, which need to meet the requirements of standardized design, factory manufacturing, and assembly-based construction in prefabricated buildings. Therefore, the research and development trend of new wall panels is moving towards lightweight, high-strength, and easy-to-install materials. Among these, autoclaved aerated concrete (ALC) wall panels are the most widely used type.
[0003] However, in architectural design, walls often require door or window openings, which poses a challenge to the overall stability of the wall structure. This is especially true for lightweight materials like ALC, which place higher demands on the securing of door and window frames; improper installation can severely impact the lifespan and performance of doors and windows. To address this issue, specific reinforcement measures must be implemented when creating door and window openings in ALC walls to ensure the structural safety and durability.
[0004] Patent CN213572478U discloses a reinforcement and waterproofing structure for window openings in ALC walls. This invention features closely spaced horizontal strips at the top of the window opening, and closely spaced vertical strips on the sides and bottom, improving the stress distribution and transmission path of the wall at the window opening. This allows the load above the window opening to be transferred to the walls on either side, preventing deformation of the window frame under pressure. However, this invention still has the following drawbacks: ① The use of horizontal strips at the top of the window opening, with the strips fitting into grooves between two connecting strips, results in a lack of support in the middle of the horizontal strips, leading to decreased structural stability; ② The use of vertical strips below the capping plate, which typically ranges in height from 0.9 meters to 1.2 meters, requires cutting multiple prefabricated ALC strips on-site, resulting in excessive material waste; ③ The capping plate uses a cast-in-place structure, and the connection between it and the prefabricated vertical strips below is not reliable, resulting in poor structural stability.
[0005] Therefore, how to solve the problems of poor structural stability and high material consumption of ALC panel wall openings for doors and windows has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0006] The present invention aims to provide a reinforcement device for door and window openings in ALC panel walls to overcome the above-mentioned shortcomings.
[0007] In order to achieve the above objectives, the technical solution of this utility model is as follows:
[0008] A reinforcement device for door and window openings in an ALC panel wall includes a steel beam, an ALC wall, and a floor slab arranged sequentially from top to bottom. Door and window openings are provided within the ALC wall, including horizontal and vertical panels. The horizontal panels are provided between the door and window openings and the steel beam, and between the door and window openings and the floor slab. The vertical panels are provided at the left and right ends of the door and window openings and the horizontal panels. Flat iron is connected to the periphery of the door and window openings and the periphery of the horizontal panels located at their top away from the steel beam.
[0009] Furthermore, the top end of the flat iron is fixedly connected to the steel beam, and the remaining part is connected to the transverse strip and / or longitudinal strip by expansion bolts.
[0010] Furthermore, the flat iron in the vertical direction is connected to the longitudinal strip via the expansion screw, and the flat iron in the horizontal direction is connected to the transverse strip via the expansion screw.
[0011] Furthermore, a capping is provided between the door / window opening and the horizontal strip at its bottom, and the lower end of the flat iron extends to the left and right into the interior of the longitudinal strip, where the capping is embedded.
[0012] Furthermore, a shear stud is fixedly connected to the inner wall of the protruding lower end of the flat iron, and the capping material is concrete, with the shear stud embedded in the capping.
[0013] Furthermore, the outer top of the capping is provided with an arc-shaped drainage slope.
[0014] Furthermore, a snap-fit groove is provided on one side of the longitudinal strip connected to the transverse strip, and both ends of the transverse strip are connected in the snap-fit groove.
[0015] Furthermore, the two ends of the horizontal strip at the top of the door and window opening are fixedly connected to the vertical strips on the left and right sides by pins inserted into the vertical strips on the left and right sides, respectively.
[0016] Furthermore, the pin is inclined downward at 45° from the transverse strip towards the longitudinal strip, and the pin is offset from the flat iron.
[0017] Compared with the prior art, this utility model has at least the following advantages:
[0018] ① In this utility model, flat iron is set around the horizontal strip at the top of the door and window opening, so that the horizontal strip at the top of the door and window opening provides multiple supports. The flat iron provides upward support force, which improves the structural stability of the device. In addition, the bottom of the door and window opening is made of horizontal strip. Compared with the traditional structure, only one side of the horizontal strip needs to be cut to meet the usage conditions, which reduces a lot of on-site construction work and reduces material waste.
[0019] ②The capping of this utility model is connected to the flat iron by shear nails, and the flat iron is connected to the horizontal strip at the bottom of the door and window opening by expansion bolts, thereby enhancing the connection between the capping and the horizontal strip at the bottom, and thus improving the structural stability of the device.
