Abstract
Description
Technical Field
[0001] This utility model relates to the field of building installation and construction technology, specifically to a non-removable cement fiberboard connecting component. Background Technology
[0002] In response to the requirement for integrated thermal insulation in building envelope structures, self-insulating blocks, thickened ALC panels, and self-insulating composite wall panels are commonly used in building envelope construction. Among these, self-insulating composite wall panels, which meet the requirements for integrated structural, thermal insulation, and decorative technologies and have significant advantages such as high industrialization, fast construction speed, and reliable quality, are experiencing rapid development.
[0003] Self-insulating composite wall cladding consists of an exterior decorative layer, a structural insulation layer, and cement fiberboard. Currently, construction typically uses wall panel supports or full-scale scaffolding to support the exterior decorative layer and cement fiberboard to prevent bulging of the wall panels during concrete pouring. However, this complex process has several drawbacks: it increases the budget cost of the wall, slows down the construction progress, and wastes the advantage of the self-insulating composite wall cladding's inherently fast construction speed. Therefore, the widespread application of self-insulating composite wall cladding is limited.
[0004] Prefabricated buildings have become a mainstream trend in the construction industry due to their unique advantages. In particular, self-insulating wall panels that do not require formwork removal not only serve as an internal insulation layer but also function as formwork. This design further simplifies the construction process and reduces costs.
[0005] However, as mentioned in the article, the bonding strength between multi-layer structures and the potential for formwork bulging during the pouring process are key issues that need to be addressed during the construction of self-insulating wall panels that do not require formwork removal.
[0006] To address the above problems, this utility model provides a non-disassembly cement fiberboard connecting component. Summary of the Invention
[0007] The purpose of this utility model is to provide a non-disassembly cement fiberboard connecting component that can firmly secure the cement fiberboard and facilitate convenient and quick installation of the connecting component, thereby solving the problems in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a non-removable cement fiberboard connecting component for fixing non-removable cement fiberboard and truss reinforcement, comprising a connecting component, which includes two mutually symmetrical steel bar clips, two fixing anchor rods, four connecting anchor rods, and a pressure plate. Each steel bar clip has six symmetrically opened round holes on both sides, and the pressure plate has four symmetrically opened round holes on both sides. The fixing anchor rods fix the two steel bar clips to the truss reinforcement through the round holes of the steel bar clips, and the connecting anchor rods pass through the round holes of the steel bar clips to fix the steel bar clips to the cement fiberboard without removal.
[0009] Furthermore, the cross-section of the steel bar clip is rectangular at both ends and semi-circular in the middle. After the steel bar clips are combined, they wrap around the truss bars, and the inner diameter is the same as the outer diameter of the truss bars, so that the truss bars are connected to each other.
[0010] Furthermore, the anchor rod passes through the round hole of the rebar clip, and both ends of the anchor rod are threaded and connected to the fixing nut. The anchor rod fixes the rebar clip to the truss bar through the fixing nut.
[0011] Furthermore, the two ends of the connecting anchor rod are threaded and respectively threaded to the wall-in-body fixing nut and the wall-out-body fixing nut. One end of the connecting anchor rod is threaded to the wall-in-body fixing nut, and the other end passes through the round hole of the steel bar clip, the round hole of the cement fiberboard, and the round hole of the pressure plate in sequence and is threaded to the wall-out-body fixing nut.
[0012] Furthermore, the pressure plate is arranged on the outside of the non-removable cement fiberboard.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. By pressing the pressure plate onto the frame of the non-removable cement fiberboard, the out-of-plane movement of the non-removable cement fiberboard can be restricted; by fixing the non-removable cement fiberboard to the truss reinforcement through connecting components, the in-plane movement of the non-removable cement fiberboard can be restricted.
[0015] 2. It can effectively connect the layers of the self-insulating composite wall enclosure, and is easy to install with a good appearance after installation;
[0016] 3. By setting installation holes and using fixed anchor rods and connecting anchor rods inserted through the installation holes to fix the connecting components, open flame operations on site can be avoided, thus improving on-site safety;
[0017] 4. This connecting component connects and fixes the cement fiberboard to the truss reinforcement without the need for dismantling, eliminating the need for formwork supports, making it economical and easy to install;
[0018] 5. This connecting component strengthens the connection between the non-removable cement fiberboard and the self-insulating composite wall structure layer, reducing the risk of the non-removable cement fiberboard falling off. Attached Figure Description
