[0011] Furthermore, in the autoclaved aerated concrete (AAC) structural wall panel leveling and installation method provided by the present invention, the adjustable bolts are post-embedded bolts, which are embedded at both ends in the vertical direction after the sealing layer is constructed, and the post-embedded bolts are chemical expansion bolts.

[0012] Furthermore, in the autoclaved aerated concrete (AAC) structural wall panel leveling and installation method provided by the present invention, chemical expansion bolts are used to embed the angle iron at both ends of the panel in the vertical direction during or after the construction of the sealing layer.

[0013] Furthermore, in the leveling and installation method for autoclaved lightweight aerated concrete structural wall panels provided by the present invention, the hook bolts of the autoclaved lightweight aerated concrete structural wall panels are installed by pre-embedding or post-embedding.

[0015] grassroots level;

[0016] The base layer is sealed, and the cast-in-place construction is carried out on the base layer.

[0017] Adjustable bolts are embedded vertically within the sealing layer and distributed at both ends of the sealing layer;

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] The present invention provides a method and structure for leveling and installing autoclaved aerated concrete (AAC) structural wall panels. This involves constructing a sealing layer on the base layer and embedding adjustable bolts and other bolts. After the concrete in the sealing layer reaches its strength, angle irons are installed at both ends of the sealing layer using the embedded bolts to form installation grooves. The AAC structural wall panels are then assembled into these grooves. The height of both ends of the AAC structural wall panels is adjusted using the adjustable bolts, thus leveling the panels. Finally, the gap between the sealing layer and the AAC structural wall panels is filled with waterproof mortar to form a waterproof mortar layer. This method achieves leveling and installation of the AAC structural wall panels on the base layer, improving the installation quality and avoiding the problem of tilted installation of AAC structural wall panels above the base layer. The mounting slots enable rapid alignment of autoclaved aerated concrete (AAC) wall panels onto the substrate and its sealing layer, facilitating quick positioning and installation. This reduces the inconvenience and cumbersome procedures associated with repeated adjustments after assembly due to inaccurate positioning. Embedded bolts ensure the reliability of the angle iron installation on the sealing layer. The waterproof mortar layer guarantees the integrity of the wall structure between the sealing layer and the AAC wall panels, ensuring a high-quality connection. The welding of hook bolts to the angle iron further enhances the reliability and quality of the connection between the AAC wall panels and the sealing layer.

[0027] The autoclaved aerated concrete (AAC) structural wall panel leveling and installation method and structure provided by this invention mainly uses adjustable bolts embedded in the construction sealing layer to level the autoclaved aerated concrete structural wall panel on the base layer.

[0033] The present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0034] Please refer to Figures 1 to 2 This invention provides a method for leveling and installing autoclaved lightweight aerated concrete structural wall panels, comprising:

[0035] Step S201: Construction of the sealing layer and installation of adjustable bolts and embedded bolts.

[0036] A fine aggregate concrete base layer 120 is formed by casting fine aggregate concrete on the base layer 110. Adjustable bolts 130 are embedded at both ends of the base layer 120 in the vertical direction during or after its construction. Embedded bolts 140 for fixing angle iron 150 are also embedded at both ends of the base layer 120 in the vertical direction during or after its construction. The embedded bolts 140 are located outside the adjustable bolts 130. Alternatively, other types of concrete can be used instead of fine aggregate concrete. The adjustable bolts 130 at both ends of the base layer 120 are symmetrically arranged, and the number of adjustable bolts 130 can be uniformly matched according to the horizontal dimensions of the base layer 120. To enable the adjustable bolts 130 to be installed within the base layer 120, the adjustable bolts 130 can be pre-embedded bolts, pre-embedded at both ends of the base layer 120 in the vertical direction during its construction. The pre-embedded bolts can be movable anchor bolts, bolt assemblies consisting of a threaded sleeve and a straight threaded rod connected by its internal thread, with the threaded sleeve pre-embedded within the base layer. The adjustable bolt 130 can also be a post-embedded bolt, installed vertically at both ends after the sealing layer 120 is constructed. This post-embedded bolt can be a standard expansion bolt or a chemical expansion bolt. In this case, the bolts need to be installed after the fine aggregate concrete of the sealing layer 120 has reached its strength. To allow the bolt 140 to be installed within the sealing layer 120, the bolt 140 can be either a standard expansion bolt or a chemical expansion bolt, installed either during the construction of the sealing layer 120 or after its construction. To improve construction efficiency, both the adjustable bolt 130 and the embedded bolt 140 in this embodiment are preferably installed using a pre-embedded method. However, when the sealing layer 120 is already completed, a post-embedded method is used, which is particularly suitable for construction projects following a previous construction project.

[0037] Step S202: Angle iron installation.

[0038] After the fine aggregate concrete of the sealing layer 120 reaches its strength, angle irons 150 are installed using embedded bolts 140. The first surface of the angle iron 150 is attached to the sealing layer 120, with the second surface facing upwards. The inner surface of the second surface is aligned with the edge line of the sealing layer 120, and the angle irons 150 at both ends of the sealing layer 120 form mounting grooves for assembling autoclaved aerated concrete structural wall panels 170. The angle iron 150 has a first and a second surface that are perpendicular to each other; it is also called an angle steel.

[0039] Step S203: Assembly and leveling of autoclaved aerated concrete structural wall panels.

[0040] The autoclaved aerated concrete (AAC) structural wall panel 170, equipped with hook bolts 160 at both ends, is assembled into the mounting groove on the sealing layer 120, such that the hook bolts 160 of the AAC structural wall panel 170 at least partially overlap with the outer surface of the second plate of the angle iron 150. The height of both ends of the assembled AAC structural wall panel 170 is adjusted using adjustable bolts 130 embedded at both ends of the sealing layer 120, ensuring that the AAC structural wall panel 170 is installed horizontally in the mounting groove. The partial overlap includes two conditions: contact without gaps and non-contact with gaps sufficient for weld width. The hook bolts 160 of the AAC structural wall panel 170 can be pre-embedded or post-embedded during construction.

[0041] Step S204: Connection and caulking of autoclaved lightweight aerated concrete structural wall panels with the sealing layer.

[0042] Angle iron 150 and hook bolt 160 on its side are welded together so that autoclaved lightweight aerated concrete structural wall panel 170 is fixedly installed on the sealing layer 120 by the welded hook bolt 160 and angle iron 150. The gap between the sealing layer 120 and the autoclaved lightweight aerated concrete structural wall panel 170 is filled with waterproof mortar to form a waterproof mortar layer 180.

[0043] Please refer to Figure 1 This invention also provides a leveling and installation structure 100 for autoclaved aerated concrete (AAC) structural wall panels, which can be constructed using the AAC structural wall panel leveling and installation method. The structure includes: a base layer 110, a sealing layer 120, adjustable bolts 130, embedded bolts 140, angle iron 150, hook bolts 160, an AAC structural wall panel 170, and a waterproof mortar layer 180. Wherein:

[0044] The base layer 110 is usually a reinforced concrete structure, typically a structural floor slab.

[0045] The base layer is 120mm thick, and the cast-in-place construction is carried out on a 110mm thick base layer.

[0046] Adjustable bolts 130 are embedded vertically within the sealing layer 120 and distributed at both ends of the sealing layer 120.

[0047] Embedded bolts 140 are embedded vertically within the sealing layer 120 and distributed at both ends of the sealing layer 120. The embedded bolts 140 are located outside the adjustable bolts 130.

[0048] Angle iron 150 is installed on the sealing layer 120 by embedded bolts 140, so that the first plate of angle iron 150 is attached to the sealing layer 120 and the second plate is arranged facing upward, so that the inner surface of the second plate is aligned with the edge line of the sealing layer 120, and the angle iron 150 at both ends of the sealing layer 120 forms an installation groove for assembling autoclaved lightweight aerated concrete structural wall panel 170.

[0049] The autoclaved aerated concrete (AAC) structural wall panel 170 has hook bolts 160 at both ends, which are fitted into mounting grooves on the sealing layer 120, such that the hook bolts 160 of the AAC structural wall panel 170 at least partially overlap with the outer surface of the second plate of the angle iron 150.

[0050] Waterproof mortar layer 180, caulking construction between sealing layer 120 and autoclaved lightweight aerated concrete structural wall panel 170.

[0051] The method and structure for leveling and installing autoclaved aerated concrete (AAC) structural wall panels provided in this invention involves constructing a sealing layer 120 on a base layer 110 and embedding adjustable bolts 130 and embedded bolts 140. After the concrete in the sealing layer 120 reaches its strength, angle irons 150 are installed at both ends of the sealing layer 120 using the embedded bolts 140 to form installation grooves. The AAC structural wall panel 170 is then assembled into the installation groove on the sealing layer 120. The adjustable bolts 130 are used to level the two ends of the AAC structural wall panel 170. The height of the end is adjusted to make the autoclaved aerated concrete (AAC) structural wall panel 170 level. Then, the gap between the sealing layer 120 and the AAC structural wall panel 170 is filled with waterproof mortar to form a waterproof mortar layer 180. This achieves leveling installation of the AAC structural wall panel 170 on the base layer 110, improves the installation quality of the AAC structural wall panel 170, and avoids the problem of tilted installation of the AAC structural wall panels 170 above the base layer 110.

[0052] The autoclaved aerated concrete (AAC) structural wall panel leveling and installation method and structure provided in this embodiment of the invention mainly uses the construction of the base layer 120 and the adjustable bolts 130 embedded therein to level the autoclaved aerated concrete (AAC) structural wall panel 170 on the base layer 110. It has the advantages of simple structure, low cost and convenient adjustment.

[0053] The autoclaved aerated concrete (AAC) structural wall panel leveling and installation method and structure provided in this embodiment of the invention enables the installation groove to quickly align the AAC structural wall panel 170 onto the base layer 110 and the sealing layer 120, thus achieving rapid positioning and installation of the AAC structural wall panel 170. This reduces the problem of cumbersome adjustment procedures and construction inconvenience caused by repeated adjustments due to inaccurate positioning of the AAC structural wall panel 170 after assembly.

[0054] The autoclaved aerated concrete (AAC) structural wall panel leveling and installation method and structure provided in this embodiment of the invention, with the embedded bolts 140 ensuring the reliability of the angle iron 150 installed on the sealing layer 120.

[0055] The leveling and installation method and structure of the autoclaved aerated concrete (AAC) structural wall panel provided in this embodiment of the invention ensures the integrity of the wall between the sealing layer 120 and the AAC structural wall panel 170 by the waterproof mortar layer 180, and also ensures the connection quality between the sealing layer 120 and the AAC structural wall panel 170.

[0056] The leveling and installation method and structure of the autoclaved aerated concrete (AAC) structural wall panel provided in this embodiment of the invention, wherein the hook bolt 160 is welded to the angle iron 150, ensures the reliability of the connection between the autoclaved aerated concrete structural wall panel 170 and the sealing layer 120, and ensures the connection quality.
