Description

Technical Field

[0001] This utility model relates to the field of secondary structure construction technology in building construction, specifically to a partition wall structure based on ultra-high autoclaved aerated concrete panels. Background Technology

[0002] Public buildings, serving the needs of the public for work, study, culture, and leisure, are increasingly favored for their high ceilings and spacious layouts. Autoclaved aerated concrete (AAC) panels, with their advantages of being lightweight and high-strength, providing thermal insulation, fire resistance, noise reduction, and environmental friendliness, are widely used in high-ceilinged and large-space building structures. However, during construction, the large length of the concrete panels presents challenges in connecting the top to the concrete floor slab, the side walls to the main wall, and adjacent panels. This can lead to problems such as panel tilting and instability, affecting the stability and safety of the wall structure and posing potential structural safety hazards later on. Utility Model Content

[0003] The purpose of this utility model is to provide a partition wall structure based on ultra-high autoclaved aerated concrete (AAC) panels. This structure adopts a multi-unit assembly method, which enhances overall stability, reduces the risk of panel cracking and overturning, and can also unload the upper-level panels to prevent the first-floor panels from being damaged by pressure. The installation is simple and convenient.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A partition wall structure based on ultra-high autoclaved aerated concrete (AAC) panels includes a concrete floor slab and a concrete wall. A support frame is installed between the concrete floor slab and the concrete wall. AAC panel units are installed on the support frame. The ends of the support frame are fixedly connected to the concrete floor slab or the concrete wall via post-embedded parts. Hangers are provided between the concrete floor slab and the support frame. L-shaped connectors are provided on the support frame, and the AAC panel units are connected to the L-shaped connectors via hook connectors.

[0006] Preferably, the post-installed component includes an anchor plate and multiple chemical anchors installed on the anchor plate.

[0007] Preferably, the support frame includes multiple square steel keels arranged longitudinally and transversely, and the ends of the square steel keels are fixedly installed on the anchor plate.

[0008] Preferably, the hanger causes the horizontally arranged square steel keel to arch upwards by 1‰.

[0009] Preferably, the L-shaped connectors are fixedly installed at both the top and bottom of the horizontally arranged square steel keel.

[0010] Preferably, steel pipe clamps are provided on the concrete floor slab, concrete wall and supporting frame, with one end of the steel pipe clamp connected to the autoclaved aerated concrete strip unit.

[0011] In this invention, the ends of the support frame are fixedly connected to the concrete floor slab or concrete wall via post-installed embedded parts. During construction, the post-installed embedded parts are pre-installed at corresponding positions according to the location of the support frame, facilitating the installation and fixation of the support frame. By using the support frame to divide the ultra-high pressure autoclaved aerated concrete (UHPA) panels into multiple units, the height of a single UHPA panel is reduced, enhancing overall stability and reducing the risk of panel cracking and overturning.

[0012] The installed hangers allow the horizontally arranged square steel keels to arch, applying prestress and unloading the upper-floor slabs to prevent damage to the lower-floor slabs due to pressure. The slabs are fixedly connected to L-shaped connectors via hook connectors, ensuring reliable connection and simple, convenient operation. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figures 1-3 The invention illustrates a partition wall structure based on ultra-high autoclaved aerated concrete (AAC) panels, comprising a concrete floor slab 1 and a concrete wall 2. In this invention, it is applied to a frame shear wall structure, wherein in some areas the first and second floors are of the same height, and the panel installation height reaches 9.8m.

[0019] A support frame 3 is installed between the concrete floor slab 1 and the concrete wall 2. The support frame 3 includes multiple square steel keels arranged longitudinally and transversely. The ends of the square steel keels are fixedly installed on the anchor plate 60 by welding.

[0020] Autoclaved aerated concrete (AAC) panel units 4 are installed on the support frame 3. The horizontally arranged square steel keel in the support frame 3 vertically divides the installation area into two areas, reducing the overall height of the panels. During installation, the gaps between two adjacent AAC panel units 4, between AAC panel units 4 and the concrete floor slab 1, between AAC panel units 4 and the concrete wall 2, and between AAC panel units 4 and the support frame 3 are filled with special mortar. The mortar joints should be full and uniform, and the fullness should be greater than 90%.

[0021] Steel pipe clamps 5 are installed on the concrete floor slab 1, concrete wall 2, and supporting frame 3. One end of the steel pipe clamp 5 is connected to the autoclaved aerated concrete (AAC) panel unit 4. The steel pipe clamp 5 serves as an auxiliary support during installation and a component for long-term fixation during subsequent use, ensuring that the connected AAC panel units 4 form a stable structural system. It provides temporary support during the installation of the AAC panel units 4, preventing tilting or displacement, and shares some of the load during long-term use, enhancing the overall stability of the AAC panel units 4 and their connection points, and improving the wind and earthquake resistance of the wall.

[0022] The ends of the support frame 3 are fixedly connected to the concrete floor slab 1 or concrete wall 2 via post-installed embedded parts 6. During construction, the post-installed embedded parts 6 are first installed at the corresponding positions according to the installation location of the support frame 3, and then the support frame 3 is installed, which facilitates the installation and fixation of the support frame 3. The post-installed embedded part 6 includes an anchor plate 60 and multiple chemical anchors 61 installed on the anchor plate 60. The anchor plate 60 is provided with connection holes, and the chemical anchors 61 pass through the connection holes to fix the anchor plate 60 to the surface of the concrete floor slab 1 or concrete wall 2. The connection holes are round holes or oblong holes.

[0023] A hanger 7 is installed between the concrete floor slab 1 and the supporting frame 3. The hanger 7 is a threaded rod, fixed by washers and nuts. During installation, the hanger 7 is adjusted so that the horizontally arranged square steel keel arches upward by 1‰. The arching creates prestress to prevent the first-floor slab from being damaged by pressure.

[0024] L-shaped connectors 8 are provided on the support frame 3, and the autoclaved aerated concrete (AAC) panel units 4 are fixedly connected to the L-shaped connectors 8 via hook connectors 9. Specifically, L-shaped connectors 8 are fixedly installed on the top and bottom of the horizontally arranged square steel keel, and the top of the first-layer AAC panel unit 4 and the bottom of the upper-layer AAC panel unit 4 are fixedly installed on the L-shaped connectors 8.

[0025] During the installation of the first-floor autoclaved aerated concrete (AAC) panel unit 4, the bottom end of the AAC panel unit 4 is fixedly connected to the concrete base slab via steel pipe clamps 5. Existing products are used for the steel pipe clamps 5, and they will not be described in detail in this manual. During construction, when encountering the construction of the replacement support steel structure, holes are drilled at the corresponding positions in the concrete floor slab 1, and the vertical steel columns are welded to the embedded parts. The horizontally arranged square steel keels are then fixed to the vertical steel columns to form a stable replacement support steel structure.

[0026] Apply anti-rust paint to the welding positions of the support frame 3 and the anchor plate 60, and apply anti-rust paint to the welding positions of the L-shaped connector 8 and the support frame 3. After one end of the hook connector 9 is fixedly connected to the L-shaped connector 8, apply anti-rust paint as well. When installing the autoclaved aerated concrete (AAC) panel unit 4, add a steel pipe clamp 5 at the upper and lower ends (800mm from the end) and at the middle position on the side of the AAC panel unit 4 closest to the structure to improve the connection strength.

[0027] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
