Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and particularly to an ALC wall panel corner structure and construction method. Background Art

[0002] Autoclaved lightweight aerated concrete (ALC) is a new type of building material. This material uses sand, stone powder, fly ash, slag, lime, cement, etc. as the main raw materials, adds a foaming agent and a bubble stabilizer, and is made through processes such as batching and mixing, casting, foaming and static stopping, cutting, and high-pressure steam curing. The ALC board has good fire resistance, fire prevention, sound insulation, heat insulation, heat preservation and other properties, and is widely used in industrial and civil buildings such as concrete structures and steel structures. The installation and construction of the ALC board is simple, which can meet people's multi-functional requirements for building safety, comfort, energy conservation, environmental protection, etc. In addition, as a wall material, the ALC board can increase the usable area by 3% - 5% compared with traditional wall materials, and has efficient and lasting heat insulation, heat preservation, and fire prevention properties, which can save heating and heat preservation energy consumption. The customized processing and on-site assembly of the ALC board reduce on-site wet operations, are less affected by dust control, and are beneficial to improving the construction level and building quality.

[0003] During the construction process, the ALC wall panel is generally a precast flat panel. In order to strengthen the connection strength at the corner, generally, one pipe clamp is used to fix each of the upper and lower ends of the ALC partition wall, and then the joint is connected through a dowel and an adhesive. This method has a large joint, and the mortar for filling the joint at the joint position will crack due to the tensile stress generated by the wall during the temperature and dry-wet cycle process, and the locking effect is still insufficient. At the same time, this construction method will result in poor corner connection force, long construction period, and low efficiency. If the board is collided when the adhesive has not yet solidified, it is easy to appear loose, and the pipe clamp fixing piece is exposed, making it difficult to construct the later decorative layer.

[0004] For example, the Chinese utility model patent with application number 202222050499.X discloses an L-shaped corner connection structure of an ALC wall panel, including a first wall and a second wall, the first wall and the second wall are arranged vertically, and hollow blocks are installed at both ends of one side of the second wall, and arc blocks are arranged symmetrically on a symmetrical side of each hollow block, and each hollow block is provided with a synchronous movement mechanism for synchronously moving two arc blocks, and a fixing mechanism for fixing the arc blocks is provided at both ends of one side of the first wall, and a connecting mechanism for mutual connection is provided between the first wall and the second wall. The utility model can connect the first wall and the second wall by setting the hollow block, the arc block, the first groove and the second groove, and the connection is convenient and fast, thereby improving the use effect of the device. However, the structure of the second wall in this scheme is complicated, and the precision requirements of the prefabricated functional ALC wall panel are high; and the cost will be greatly increased by adding mobile components in the wall, which limits its application.

[0005] The Chinese utility model patent with application number CN215977913U provides an ALC interior partition wall panel corner connection card, including a U-shaped connection card and a U-shaped connection card 2, the connection card 1 includes a bottom plate 1, the sides of the bottom plate 1 are respectively fixed with side plates 2 and 3, the connection card 2 includes a bottom plate 2, the sides of the bottom plate 2 are respectively fixed with bottom plate 1 and side plates 4, the side plates 2 and the bottom plate 2 are connected as one body, the utility model can improve the construction efficiency and increase the connection force of the two ALC wall panels at the corner, increase the locking effect of the wall panels, reduce the difficulty of operation, and effectively protect the corners of the wall from being damaged. However, the structure uses the upper and lower connection cards of the ALC wall panels for connection, and installs a through-type screw at the end of the wall, which has a large hole and is prone to the risk of breakage; in addition, the connection structure has high requirements on the material stiffness. If the material thickness is too large, it will affect the construction of the decorative layer.

[0006] In summary, an ALC wall panel corner structure and construction method is provided to reduce the construction difficulty of conventional corner connections, effectively improve construction efficiency, reduce the number of wall pins and enhance stability, which is of great significance for expanding the application of ALC wall panels.

[0020] The present invention will be further described below by way of examples, but the present invention is not limited to the scope of the described examples. The experimental methods without specific conditions in the following examples are carried out according to conventional methods and conditions, or selected according to the product instructions.

[0021] Example 1 The ALC wall panel corner structure of this embodiment includes a wall body and a fixing member for connecting and fixing it. Among them, the wall body is the ALC wall body 1 at the corner, the first ALC wall panel flat wall body 2, and the second ALC wall panel flat wall body 3. The fixing member is a butterfly-shaped double-sided U-shaped clamp 4 and a fixing pipe clamp 5.

[0022] As Figure 1 shown, the left and right sides of the ALC wall body 1 at the corner are respectively connected to the first ALC wall panel flat wall body 2 and the second ALC wall panel flat wall body 3. On the connection interfaces in the vertical direction, a plurality of butterfly-shaped double-sided U-shaped clamps 4 are evenly arranged on both sides. Combining Figure 1 , Figure 2 , the fixing pipe clamp 5 is fixed to the upper and lower parts of the wall body to connect the ALC wall body 1 at the corner and the flat wall body.

[0023] As Figure 3 shown, the structure of the butterfly-shaped double-sided U-shaped clamp 4 is a single-sided U-shaped fixing piece 401 arranged on both sides of the bottom plate and staggered up and down. The side plate of the single-sided U-shaped fixing piece 401 is provided with a pin fixing hole 402. When in use, the pin is inserted into it to fix the butterfly-shaped double-sided U-shaped clamp 4 to the walls connected on the left and right sides.

[0024] As Figure 4 shown, the fixing pipe clamp 5 includes a pipe clamp bottom plate and a hollow metal pipe vertically arranged on one side of the pipe clamp bottom plate. When in use, the hollow metal pipe is anchored at one place of the L-shaped corner ALC wall body 1 or the flat wall body, and the bottom plate is anchored to the other wall body through a nail gun.

[0025] According to the above implementation method, the ALC wall panel corner structure adopts a three-section connection method, and can complete the assembly of wall panel corner structures at different angles according to the actual processing needs of building wall corners. This embodiment simplifies the connection structure at the corner, effectively enhances the structural stability, and maximally utilizes the original strength of the materials. By adopting the butterfly-shaped double-sided U-shaped clamp 4, it combines the traditional single-sided U-shaped clamp, has the function of fixing on both sides, and staggering the positions of the U-shaped clamps up and down is also beneficial for installation. Installing and fixing the fixing pipe clamp 5 on the upper and lower parts of the L-shaped ALC wall panel at the corner can effectively hide the pipe clamp, reducing inconvenience for later decoration construction.

[0026] Embodiment 2 The ALC wall panel corner structure of this embodiment adopts the ALC wall body 1 at the L-shaped corner with a wall corner angle of 90° on the basis of the structure of Embodiment 1.

[0027] According to the above implementation method, the ALC wall body 1 at the L-shaped corner can improve the convenience of ALC wall panel installation. At the same time, compared with the flat ALC wall panel, the L-shaped ALC wall panel structure is small in volume, light in weight, convenient for transportation and installation, and can meet the wall panel corner requirements in most application scenarios.

[0028] Example 3 The corner structure of the ALC wall panel in this example is basically the same as that in Example 2. In this example, at the connecting interfaces of the ALC wall body 1 with the first ALC wall panel flat wall body 2 and the second ALC wall panel flat wall body 3 at the corner in the vertical direction, four butterfly-shaped double U-shaped clips 4 are respectively arranged evenly. Each side of the butterfly-shaped double U-shaped clip 4 is located at one-third to two-thirds of the wall height from bottom to top.

[0029] According to the above implementation manner, the number of the butterfly-shaped double U-shaped clips 4 is four and they are arranged evenly at both sides of the connection, increasing the force-bearing connection points and saving the materials for fixing, and minimizing the loss of the ALC wall panel structure to the greatest extent.

[0030] Example 4 Based on Example 3, this example uses hot-dip galvanized Q235 steel to prepare the butterfly-shaped double U-shaped clip 4 and the fixed pipe clip 5. The 2-mm-thick hot-dip galvanized Q235 steel raw material is processed into the shape of the butterfly-shaped double U-shaped clip 4, and a pin fixing hole 402 is drilled at the center of the single-side U-shaped fixing piece 401; similarly, in the fixed pipe clip 5, the hot-dip galvanized Q235 steel raw material is made into a rectangular pipe clip bottom plate with a length ≥ 170 mm and a width ≥ 45 mm, and a hollow metal pipe with a height of 80 mm, a diameter of 15 mm, and a pipe thickness of 1.2 mm. In actual assembly, the above original component parameters can be flexibly adjusted according to the design requirements of the wall body.

[0031] According to the above implementation manner, the dense protective layer on the surface of the hot-dip galvanized Q235 steel can effectively isolate oxygen and moisture, preventing the steel from oxidizing and rusting. In humid, acid-base environments or outdoor exposure conditions, its corrosion resistance is significantly better than that of ordinary carbon steel. The zinc layer has the self-repairing property. Even if it is scratched locally, the sacrificial anode protection effect of zinc can still continuously slow down the corrosion and extend the service life. As a low-carbon steel, Q235 steel has a mature production process, low raw material prices, and controllable galvanizing treatment costs, with good comprehensive economy, and is especially suitable for engineering scenarios with high requirements for cost control and durability.

[0032] Example 5 This example provides a construction method for the corner structure of the ALC wall panel in Example 4, and the steps are as follows: (1) Selection of ALC wall panels: According to the design requirements of the construction site, the wall body is typeset, and after completion, the number of corner positions is counted, and the wall body is customized according to the number; (2) Substrate treatment: After the structural floor slab is poured, the substrate is cleaned, the wall body is positioned and the line is drawn, and a special bonding mortar is laid before installation; (3) Fixing of the L-shaped ALC wall panel at the corner: The fixed pipe clip is installed on the upper and lower parts of the L-shaped ALC wall panel and anchored to the structure by shooting nails, and the ALC wall panel is installed at the fixed position; (4)Install the butterfly-shaped double-sided U-shaped clamp: First install the butterfly-shaped double-sided U-shaped clamp on both sides of the L-shaped ALC wall panel and fix it with pins. The butterfly-shaped double-sided U-shaped clamp is fixed at one-third and two-thirds of the height, and two are installed on each side respectively. (5)Install the flat wall: After the base is cleaned and the wall is positioned and marked, apply special adhesive mortar at the bottom. The special adhesive mortar needs to be scraped and applied at the joint of the wall. Then install the vertical flat wall panels on both sides. Install the vertical flat wall panels on one side of the butterfly-shaped double-sided U-shaped clamp and fix them with pins. (6)Seal the joints: Then process the joints of the installed wall, paste alkali-resistant fiberglass mesh cloth, and apply special putty for closing the opening.

[0033] The construction method of the present invention has the advantage of convenient construction, reduces the construction difficulty, and effectively improves the construction efficiency.
