Multi-curvature grg limit adjustment connection design structure for wet space

Abstract

This invention provides a multi-curvature GRG limiting and adjusting connection design structure for humid spaces. It includes several GRG plates with several exposed screws pre-embedded on them, a perforated angle iron with connecting screws on it, and hooks at the bottom of the connecting screws; and a steel plate with a bidirectional internal thread bearing on it. The hooks are connected to the steel plate, and the exposed screws are screwed onto the bidirectional internal thread bearing. This invention forms a sleeve limiting mode through the exposed screws and the bidirectional internal thread shaft. By rotating the bidirectional internal thread shaft, the spacing between adjacent GRG plates is controlled, allowing for gap repair and preventing uneven gap sizes that could lead to cracking during later repairs. Furthermore, by pre-embedding T-shaped steel plates and I-shaped pre-embedded parts within the GRG plates, connected by rivets, the overall GRG hanging force is increased, preventing the hanging parts from falling off due to moisture in humid environments.

Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, and more specifically, to a multi-curvature GRG limit adjustment connection design structure for damp spaces. Background Technology

[0002] GRG (Glass Reinforced Plastic) is primarily made of gypsum and fiberglass, and its breaking load is 10 times that of ordinary gypsum. It is also a non-combustible material, making it suitable for various spaces. However, in humid and hot environments, gypsum absorbs moisture, which can lead to reduced strength, expansion, and cracking. When multi-curvature GRG modules are assembled and connected, these quality issues become more severe and require further solutions.

[0003] Currently, GRG hangers are pre-embedded at the factory and welded to the base steel frame on site. The process involves laying out lines on-site according to drawings, and then welding the base. Because the curvature of the GRGs varies in different areas, it's necessary to determine the starting point for dry-hanging the GRGs. Furthermore, the hanging points for GRGs with different curvatures cannot be standardized, requiring several people to hold the GRGs while welding the hangers to the base. When installing adjacent GRGs, they are hoisted according to pre-arranged numbers. However, to ensure consistent curvature between two GRGs, the GRGs need to be slowly moved and adjusted while being held before welding the pre-embedded parts to the steel frame. This leads to the following problems: 1. The entire GRG is made of gypsum, which has a high density and heavy weight. When the curvature of the GRG is adjusted during assembly, multiple people need to lift the GRG while welders weld and fix the embedded parts to the steel frame. This reduces work efficiency and the on-site welding can easily cause safety accidents. 2. When splicing two GRG pieces, a gap width of 5-8mm is required to ensure a firm bond and prevent cracking or detachment of the repair material. However, with multi-curvature GRGs, the gap between adjacent pieces cannot be adjusted after welding, leading to inconsistent gap sizes and even tight gaps. This makes it difficult to meet the required gap width, resulting in cracking and detachment. Since the curvature cannot be adjusted again after welding, manual sanding is necessary. However, GRG is a hard material, making sanding time-consuming, labor-intensive, and difficult to control the curvature during sanding.

[0004] 3. Because the embedded parts in conventional curvature GRG only consider the embedding depth and not the embedding overlap length, the strength of GRG decreases in humid and hot environments, and there is a risk of falling off. Therefore, the connection and fixing of GRG hangers and steel frame base has resulted in a waste of human resources. At the same time, there are unsafe factors in the construction process, which may lead to potential safety accidents. Furthermore, the two adjacent GRG hangers cannot be adjusted again, and cracking occurs during later repairs. In humid and hot environments, the strength of GRG decreases, which may cause the pre-embedded dry hangers to fall off. Utility Model Content

[0005] In view of this, the present invention provides a multi-curvature GRG limit adjustment connection design structure for humid spaces, which solves the problems of the inability to adjust two adjacent GRGs for the second time, resulting in cracking after repair; and the risk of GRG strength reduction and dry-hanging component detachment caused by the pre-embedded parts falling off in humid and hot environments.

[0006] Therefore, on the one hand, this utility model provides a multi-curvature GRG limiting adjustment connection design structure for humid spaces, which includes: Several GRG plates, with several exposed screws pre-embedded on them. A perforated angle iron with a connecting screw on it and a hook at the bottom of the connecting screw; The steel plate has a double-sided internal thread bearing installed on it, the hook is connected to the steel plate, and the exposed screw is screwed onto the double-sided internal thread bearing.

[0007] Furthermore, the aforementioned bidirectional internal thread bearing includes a fixed bearing and a bidirectional internal thread shaft, with a limiting hole provided on the steel plate, and the fixed bearing connected within the limiting hole.

[0008] Furthermore, the aforementioned bidirectional internal thread shaft is provided with a threaded groove, and the exposed screw is threaded into the threaded groove.

[0009] Furthermore, the aforementioned connecting screw is fixed to the punched angle iron by a nut, and a spring washer is provided at the bottom of the nut.

[0010] Furthermore, a T-shaped embedded steel plate is pre-embedded inside the aforementioned GRG plate.

[0011] Furthermore, a straight-line embedded part is also pre-embedded in the above-mentioned GRG plate, and the straight-line embedded part is fixed by rivets.

[0012] This utility model provides a multi-curvature GRG limiting and adjusting connection design structure for humid spaces. It utilizes a bidirectional internal thread bearing mounted on a steel plate. The bidirectional internal thread bearing includes a fixed bearing and a bidirectional internal thread shaft with a threaded groove. An exposed threaded rod is pre-embedded in the GRG plate. When two GRG plates need to be installed, the bidirectional internal thread shaft is simply screwed onto the exposed threaded rod. The exposed threaded rod and the bidirectional internal thread shaft form a sleeve limiting mode. By rotating the bidirectional internal thread shaft, the distance between adjacent GRG plates is controlled, allowing for the repair of gaps and preventing uneven gap sizes during later repairs. To prevent cracking, the steel plate is hung in the hooks for simplified installation, avoiding the need for multiple people to lift the GRG plate while one person welds and fixes it, thus reducing safety hazards associated with welding. The height and curvature of the GRG plate are controlled by adjusting the nuts, reducing the time and effort required for manual repair and grinding later. Exposed bolts are pre-embedded into the GRG plate at the factory, and T-shaped and straight-line embedded steel plates are also pre-embedded in the GRG plate. The T-shaped and straight-line embedded steel plates are connected by rivets, increasing the overall load-bearing capacity of the GRG and preventing the hangers from falling off due to moisture in humid and hot environments.

[0013] Therefore, this embodiment has the following advantages compared to the prior art: A multi-curvature GRG limit adjustment connection design structure for humid spaces solves the problems of the inability to adjust two adjacent GRGs for the second time, resulting in cracking during later repairs; and the risk of GRG strength reduction and detachment of pre-embedded dry-hanging components in humid and hot environments.
