Description

Technical Field

[0001] This utility model belongs to the technical field of cement-based wall panels, and in particular relates to lightweight cement-based wall panels. Background Technology

[0002] Lightweight cement-based wall panels, as a new type of building wall material, are building wall panels made of cement as the main cementing material, combined with sand, aggregates, fibers (such as glass fiber, cellulose, etc.) and other auxiliary materials (such as admixtures, lightweight aggregates, etc.) through specific processes (such as mixing, pouring, curing, etc.). They have good mechanical properties, fire resistance, durability and construction adaptability, and are increasingly widely used in prefabricated buildings and green buildings.

[0003] The construction process often uses splicing and adhesive bonding, which results in low shear strength. When subjected to vibration or impact, the joints are prone to cracking and the wall panels may fall off. In addition, due to the installation method (side-mounted support nodes), mechanical components protrude around the wall panels. Therefore, it is necessary to provide lightweight cement-based wall panels. Multiple wall panels can be installed and fixed by structural reinforcement and quick connection between two wall panels. At the same time, crack-resistant treatment is used to ensure the smoothness of the wall surface. Utility Model Content

[0022] In the following description, embodiments of the lightweight cement-based wall panel of this utility model will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates a lightweight cement-based wall panel according to an embodiment of the present invention, comprising a cement-based structural panel 2 located below a wall 1; a light steel keel 4 is provided between two cement-based structural panels 2; rectangular grooves 3 are provided on both sides of the cement-based structural panels 2, and the light steel keel 4 is located in the inner cavity of the rectangular grooves 3. The rectangular grooves 3 provide pre-set installation space for the light steel keel 4, thereby ensuring a tight connection between the two cement-based structural panels 2 and improving the installation strength of the cement-based structural panels 2 after construction; two first bolts 5 are provided through the right side of the light steel keel 4, and the left end of the first bolts 5 extends through to the left side of the light steel keel 4 and is embedded inside the cement-based structural panel 2; locking components 6 are provided at the top and bottom of the light steel keel 4, and the locking components 6 include expansion sleeves 61, which are embedded inside the wall 1; connecting clips 62 are welded to the surface of the expansion sleeves 61, and connecting clips 62 are also provided. A second bolt 64 is installed through the right side of the 2. The left end of the second bolt 64 extends through to the left side of the light steel keel 4 and is fixedly connected to the cement-based structural plate 2. An expansion bolt 7 is installed through the inner cavity of the expansion sleeve 61. A nut 8 is threadedly connected to the bottom of the surface of the expansion bolt 7. The expansion bolt 7 and the nut 8 work together to fix the expansion sleeve 61 and compress it internally, thereby strengthening the connection stability between the expansion sleeve 61 and the wall 1. Multiple annular anti-detachment protrusions 9 are fixedly connected to the surface of the expansion sleeve 61. Limiting slots 63 are opened at the top and bottom of the light steel keel 4. The connecting clip 62 is engaged in the inner cavity of the limiting slot 63. A hanging mesh 10 is attached to the front and back sides of the joint of the two cement-based structural plates 2. A mortar layer 11 is applied to the surface of the cement-based structural plate 2. A lime layer 12 is applied to the surface of the mortar layer 11.

[0024] Working Principle: In use, the user installs the first cement-based structural slab 2. After installation, a light steel keel 4 is laid in the inner cavity of the rectangular groove 3 on the right side of the cement-based structural slab 2 and fixed with the first bolt 5. Then, the user drills installation holes on the surface of the wall 1, engages the connecting clip 62 in its inner cavity, and taps the expansion sleeve 61 into the inner cavity of the installation hole. Next, the user rotates the nut 8. During rotation, the nut 8, through the interaction of its inner thread and the surface thread of the expansion bolt 7, engages the expansion bolt 7. As the expansion bolt 7 slides, it compresses the inner wall of the expansion sleeve 61, causing the expansion sleeve 61 to deform and expand, thereby enhancing the contact strength between the expansion sleeve 61 and the wall 1. Then, the user inserts the second bolt 64 from right to left into the inner cavity of the connecting clip 62, while simultaneously inserting the second bolt 64 through the light steel keel 4 and into the inner wall of the cement-based structural board 2. Then, the user lays the hanging mesh 10 at the contact position of the two rectangular slots 3, and applies a mortar layer 11 to the surface of the rectangular slots 3 and the hanging mesh 10. After the mortar layer 11 has completely solidified, a white lime layer 12 is applied to the surface of the mortar layer 11.

[0025] In summary, this lightweight cement-based wall panel, through the setting of the locking component 6, fixes the position of the light steel keel 4. At the same time, with the cooperation of the light steel keel 4 and the first bolt 5, the supporting strength of the cement-based structural panel 2 is enhanced. Finally, with the cooperation of the mortar layer 11 and the lime layer 12, the surface of the multiple rectangular grooves 3 is leveled and uniformly finished, thus achieving the purpose of simple and fast construction and high supporting strength.
