Description

Technical Field

[0001] The utility model relates to the technical field of ALC wall panels, in particular to a hidden connection device of autoclaved lightweight concrete wall panels and a wall structure thereof. Background Art

[0002] Autoclaved Lightweight Concrete (ALC) wall panels are a kind of porous concrete panels that are made by combining fly ash (silica sand), cement, lime and other selected raw materials, and reinforced with built-in steel mesh, and refined through a high-pressure steam curing process. This type of panel is not only suitable for wall construction, but also suitable as a roofing material. It is characterized by its light weight and excellent strength, as well as excellent thermal insulation, sound insulation, and earthquake resistance and fireproof performance. In addition, the ALC panel's cut-to-length production and rapid installation characteristics, coupled with its energy-saving and environmental protection advantages, as well as its easy cutting, carving and fixing during the construction process, make it a high-quality choice in the field of green buildings.

[0003] However, despite the increasing use of ALC wall panels in construction, their traditional connection methods, such as hook bolts, U-shaped steel clamps or pipe clamps, often damage the panels, and the exposure of the connection devices also affects the overall aesthetics. More importantly, when the wall is subjected to horizontal loads, due to construction defects or stress concentration around the connection devices, ALC wall panels are prone to cracks or damage in these areas.

[0004] Therefore, the market urgently needs a new type of ALC wall panel connection structure, which should have the characteristics of simple structure, convenient installation, elegant appearance, reliable quality, and minimize damage to the wall. Such innovation will greatly enhance the application potential and user experience of ALC wall panels in modern buildings.

[0005] In view of this, the applicant filed this application after studying the existing technology. Utility Model Content

The slide member 1 is provided with a T-shaped slide. The first end of the connecting member 3 is engaged with the long sheet member 2. The second end of the connecting member 3 is provided with a T-shaped sliding portion capable of being embedded in the slide. The T-shaped sliding portion can be slidably embedded in the slide. Preferably, the material of the long sheet member 2 is Teflon or EVA plastic foam. The material of the slide member 1 is steel. The material of the connecting member 3 is steel. The fastener 4 is an expansion bolt.

[0031] On the basis of the above-mentioned embodiment, in an optional embodiment of the present invention, a plurality of first strip holes are provided at both ends of the long sheet-like member 2. A plurality of second strip holes are provided at the first end of the connecting member 3. The first strip hole and the second strip hole completely overlap. The fastener 4 can pass through the first strip hole and the second strip hole to be combined with the end of the ALC wall panel 6. Preferably, the direction of the long sheet-like member 2 is arranged along the direction of the ALC wall panel 6. The fastener 4 can move in the first strip hole and the second strip hole along with the ALC wall panel 6. The long sheet-like member 2 is arranged on the surface of the raised part at the end of the ALC wall panel 6. Four first strip holes are provided at each end of the long sheet-like member 2.

[0032] In this embodiment, the slide member 1 is a track made of steel, which is fixed on the columns 5 on both sides of the ALC wall panel 6. Its notch has a shape that matches the end of the connecting member 3, so that the connecting device is connected to the column 5 through the connecting member 3, so that the installation of the connecting device does not cause damage to the column 5. The long sheet member 2 is arranged on the surface of the raised part of the upper end of the ALC wall panel 6, and has four oblong holes at both ends for the fastener 4 to penetrate and move. The connecting member 3 is made of high-strength steel, arranged on the upper surface of the two ends of the long sheet member 2, and its end has a flange that matches the slide member 1 and is placed in the notch of the slide member 1, and the same hole is arranged at the position corresponding to the hole of the long sheet member 2.

The connection device of the hidden autoclaved lightweight concrete wall panel can be arranged horizontally or vertically according to the arrangement direction of the wall panel.

[0033] The long sheet-like member 2 is made of Teflon or EVA plastic foam, which is thin and has a low friction coefficient. When used as the intermediate material between the two ALC wall panels 6, when the wall is subjected to horizontal loads, the friction between the upper and lower wall panels can be reduced, allowing the wall panels to slide relative to each other, thereby protecting the ALC wall panels 6 from damage. The long sheet-like member 2 and the T-shaped steel plate have oblong bolt holes, which allow the fasteners 4 fixed on the ALC wall panels 6 to move with the wall panels when the wall is subjected to horizontal loads, thereby ensuring that the connection device is not damaged. The fasteners 4 are expansion bolts to enhance the connection strength of the connection device.

[0034] The construction method of the hidden autoclaved lightweight concrete wall panel connection device of the embodiment of the present invention is as follows:

[0035] S1: Reserving corresponding recessed portions of the slide member 1 on the columns 5 on both sides of the wall panel, and embedding the slide member 1 into the columns 5;

[0037] S3: Hang the next ALC wall panel 6 on the connecting device, and repeat the above operation to stack and install.

[0038] Compared with the prior art, the connection device has a simple structure, reliable quality, beautiful appearance, and is easy to process and install. The long sheet-like piece made of Teflon or EVA plastic foam has a low friction coefficient. When it is placed between two wall panels, when the wall is subjected to horizontal load, the two wall panels above and below the connection device can be allowed to slide relative to each other, protecting the wall panel structure from damage. The T-shaped steel sheet is connected to the side column through a slide groove. This connection does not require damage to the side column, and the connection device is invisible after the wall panel construction is completed, which can make the wall as a whole more beautiful and greatly reduce the damage to the ALC wall panel and the connection device caused by adverse loads.
