[0002] Autoclaved aerated concrete (ALC) panels are a new type of building material with superior properties such as low density and high strength. Therefore, they can be used as exterior wall materials for residential, commercial, and industrial buildings. Currently, existing ALC panels are generally installed by directly butt-jointing them together; however, after the exterior wall is installed, it will undergo thermal expansion and contraction deformation when exposed to changes in external temperature, leading to cracks at the joints and affecting the safety and stability of the exterior wall structure.

[0003] Therefore, those skilled in the art have provided an autoclaved lightweight aerated concrete panel exterior wall structure to solve the problems mentioned in the background art. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: an autoclaved lightweight aerated concrete panel exterior wall structure, comprising: a wall panel, wherein square grooves are respectively formed on its upper and lower end faces, and connecting grooves are respectively formed on its left and right end faces;

[0005] A square steel cylinder is used to be fitted and sealed in the square groove cavity;

[0008] In an optional embodiment, the locking connecting rod includes a vertical support part and a horizontal locking part that are integrally formed and arranged alternately in the vertical direction. The horizontal locking part has U-shaped openings at both ends for connecting the locking ring.

[0009] Furthermore, the wall panel is provided with a locking post hole that can penetrate the locking ring and the U-shaped opening, and a locking post is passed through the locking post hole;

[0010] Furthermore, the transverse locking part has a cross cavity in the front-to-back direction, and a cross support frame is installed in the cross cavity;

[0012] In an optional embodiment, the transverse locking portion includes an arc-shaped portion arranged in a cross structure, and the arc-shaped portion has an arc-shaped opening layer.

[0013] In an optional embodiment, the cross support frame includes: a support cylinder that can be concentrically assembled with the semi-column slot, and four sliding columns are fixedly assembled on its outer wall, and its inner wall is provided with a threaded groove.

[0014] The fixed cylinders are respectively embedded and fixedly assembled in the cross cavity wall, and are slidably connected to the slide column outside the slide column. A compression spring is elastically connected between the fixed cylinder and the slide column in the sliding fit.

[0015] Hook bolts have protruding threads on their bolt surfaces that can engage with threaded grooves.

[0016] In an optional embodiment, the vertical support portion has a flat cavity that extends vertically and connects to a cross-shaped cavity.

[0017] In an optional embodiment, the arc-shaped portion includes a steep arc portion located on the middle side, a beveled portion located on the horizontal and vertical sides of the steep arc portion and smoothly tangent to each other, a sloping arc portion located on the outer horizontal end side of the sloping portion on the horizontal side and the outer vertical end side of the sloping portion on the vertical side and smoothly tangent to each other, and a planar portion located on the outer end of the sloping arc portion on the outer horizontal end side and the outer end of the sloping arc portion on the outer vertical end side and smoothly tangent to each other.

[0020] In an optional embodiment, the opening of the locking ring is oriented perpendicular to the top and bottom surfaces.

[0021] In an optional embodiment, the opening of the locking ring is perpendicular to the front and rear sides.

[0022] Compared with the prior art, the present invention provides an autoclaved lightweight aerated concrete panel exterior wall structure, which has the following beneficial effects:

[0023] 1. The square steel cylinder cavity setting and locking connecting rod setting structure in this invention have excellent support strength and can compensate for the assembly gap on the outside of the wall panel by the rigid deformation of the square steel cylinder and locking connecting rod when the wall panel is affected by the external ambient temperature. For example, when the wall panel is heated and impacted, the square steel cylinder is forced to compress and the cavity volume shrinks, safely and stably generating a certain rigid deformation. The rigid deformation of the locking connecting rod compensates for the gap between the wall panels, thereby ensuring the airtightness and support strength at the interface of the assembly gap on the outside of the wall panel.

[0024] 2. The structure in this invention, in which the locking ring is pre-connected in the steel frame and the locking column penetrates the wall panel, makes the connection strength of the wall panel to wall panel more robust and stable. It also helps to distribute the locking stress of the locking connecting rod evenly in the wall panel. On the one hand, it avoids the uneven locking stress on the wall panel caused by local locking and fixing. On the other hand, it can increase the upper limit of the locking stress, thereby improving the stability of the wall panel to wall panel assembly connection. Attached Figure Description

[0032] refer to Figure 1-5 The present invention provides a technical solution: an autoclaved lightweight aerated concrete panel exterior wall structure, comprising: a wall panel 1, wherein square grooves 11 are respectively opened on the upper and lower end faces, and connecting grooves 12 are respectively opened on the left and right end faces;

[0033] The square steel cylinder 2 is used for locking and sealing in the square groove 11;

[0034] Locking ring 7 is welded to the left and right sides of the steel frame 6 inside the wall panel 1 and exposed in the connecting groove 12;

[0035] The locking connecting rod 3 is used to be fitted into the adjacent connecting groove 12, and its left and right ends are respectively connected to the corresponding locking rings 7;

[0036] The square steel cylinder cavity and locking connecting rod structure have excellent support strength and can compensate for the assembly gaps on the outside of the wall panel by means of the rigid deformation of the square steel cylinder and locking connecting rod when the wall panel is affected by the external temperature. For example, when the wall panel is heated and impacted, the square steel cylinder is forced to compress and the cavity volume is reduced, which safely and stably generates a certain rigid deformation. The rigid deformation of the locking connecting rod compensates for the gaps between the wall panels, thereby ensuring the airtightness and support strength at the interface of the assembly gaps on the outside of the wall panel.

[0037] In this embodiment, the locking connecting rod 3 includes a vertical support part 31 and a horizontal locking part 32 that are integrally structured and arranged vertically alternately. The horizontal locking part 32 has U-shaped openings 321 at both ends for connecting the locking ring 7.

[0038] Furthermore, the wall panel 1 is provided with a locking post hole 14 that can penetrate the locking ring 7 and the U-shaped opening 321, and a locking post 8 is passed through the locking post hole 14;

[0039] Furthermore, the transverse locking part 32 has a cross cavity 322 in the front-to-back direction, and a cross support frame 5 is installed in the cross cavity 322;

[0040] Furthermore, the left and right end faces of the wall panel 1 are provided with semi-column slots 13 that are concentric with the front and rear center lines of the cross cavity 322;

[0041] The structure of the locking ring being pre-connected in the steel frame and the locking column penetrating the wall panel makes the connection strength of the wall panel to wall panel stronger and more stable. It also helps to distribute the locking stress of the locking connecting rod evenly in the wall panel. On the one hand, it avoids the uneven locking stress on the wall panel caused by local locking and fixing. On the other hand, it can increase the upper limit of the locking stress, thereby improving the stability of the wall panel to wall panel assembly connection.

[0042] In addition, the cross cavity and cross support frame in the transverse locking part are designed as a safe and stable rigid structure that generates the main rigid deformation in the locking connecting rod structure. This allows the rigid deformation of the transverse locking part to compensate for and absorb the displacement deformation and vibration fluctuations of the wall panel when it is subjected to certain deformation and vibration, thus ensuring the stability and strength of the wall panel support.

[0043] In this embodiment, the transverse locking part 32 includes an arc-shaped part 33 arranged in a cross structure, and the arc-shaped part 33 has an arc-shaped opening layer 3311. Through the structural design of the arc-shaped opening layer, the toughness and safety strength of the arc-shaped part under tensile and compressive deformation can be further improved.

[0044] In this embodiment, the cross support frame 5 includes: a support cylinder 51, which can be concentrically assembled with the semi-column slot 13, and four sliding columns 52 are fixedly assembled on its outer wall, and its inner wall is provided with a threaded groove 511.

[0045] The fixed cylinder 53 is respectively embedded in the wall of the cross cavity 322 and is slidably connected to the slide column 52 outside the slide column 52. A compression spring 54 is elastically connected between the fixed cylinder 53 and the slide column 52 that are slidably engaged.

[0046] The hook bolt 4 has a protruding thread 41 on its bolt post surface that can engage with the threaded groove 511.

[0047] One installation method for the cross support frame is as follows: First, after assembling the compression spring, sliding column, and fixing cylinder, one end of the fixing cylinder is embedded in the cross cavity wall and welded in place. Then, an external pressure clamping device is used to compress the four sliding columns near the center. The support cylinder is then placed in the center, and the compression on the sliding columns is slowly released using the pressure clamping device, causing the sliding columns to embed in the locking grooves on the outer wall of the support cylinder. Finally, welding is performed. It is important to note that the compression spring can be pre-selected based on the required pre-set elastic force. This ensures that when the wall reaches a certain threshold, the locking connecting rod undergoes rigid deformation, which helps balance the stability of the wall. Furthermore, combined with... Figure 3 As shown, the number and spacing of the protruding threads on the hook bolts need to be set according to the corresponding number and spacing of the locking connecting rods before and after, so as to fix the support cylinder; specifically, combined with Figure 4 As shown, when the wall panel produces the locking connecting rod as follows Figure 4 When the applied stress is as shown, it will immediately act on the arc-shaped part to produce rigid deformation for compensation. This helps to reduce the direct force and the intensity of the force in unstable directions on the hook bolt and support cylinder, thereby ensuring the firmness and strength between the wall panels.

[0048] In this embodiment, the vertical support 31 has a flat cavity 311 that runs vertically through and connects to the cross cavity 322, which further enhances the rigid deformation compensation safety effect between the wall panels.

[0049] In this embodiment, the arc-shaped portion 33 includes a steep arc portion 331 located in the middle, a slope portion 332 located on the horizontal and vertical sides of the steep arc portion 331 and smoothly tangent to each other, a sloping arc portion 333 located on the outer horizontal end side of the sloping arc portion 332 and the outer vertical end side of the sloping arc portion 332 and smoothly tangent to each other, and a flat portion 334 located on the outer end side of the sloping arc portion 333 and the outer end side of the sloping arc portion 333 and smoothly tangent to each other, making rigid deformation safer and tougher.

[0050] In this embodiment, the arc-shaped layer 3311 is formed at the steep arc portion 331.

[0051] In this embodiment, the locking connecting rod 3 is configured with multiple different widths, and the locking connecting rod 3 with a larger front and rear width has a vertically opened arc-shaped opening 34 on the outside of the arc-shaped part 33 of the transverse locking part 32. That is to say, during the wall panel installation and assembly process, locking connecting rods of different widths can be used to assemble and lock the gaps between the wall panels. Figure 3 As shown, this width specification can be used for multiple consecutive assembly gaps between wall panels, and then a further selection can be made as follows: Figure 5 The specifications shown allow for segmented differentiation of the deformation and vibration experienced by continuously assembled wall panels. In other words, for example, in one embodiment, a selection is made every n wall panel assembly gaps. Figure 5 As shown in the specifications, the remaining assembly gaps are handled as follows: Figure 3 As shown in the specifications, when the locking connecting rods of the same specification undergo relatively uniform small rigid deformation, and then the wide locking connecting rod provides a larger rigid deformation, the assembly and connection of the wall panels becomes more flexible, and at the same time, the overall strength of the wall panels is further improved.

[0052] In this embodiment, the direction of the locking ring 7 is perpendicular to the top and bottom surfaces. That is to say, in this selection method, the direction of the locking post hole and the locking post is set vertically, so that the locking stress of the locking connecting rod is evenly distributed vertically.

[0053] Reference Figure 6 As shown in this embodiment, the direction of the locking ring 7 is perpendicular to the front and rear. In other words, in this selection method, the direction of the locking post hole and the locking post is set laterally, so that the locking stress of the locking connecting rod is evenly distributed laterally. This further improves the support strength of the wall, the locking and securing strength, and the effect of resisting torsional stress while ensuring that the locking connecting rod has excellent rigid deformation on the wall panel.

[0054] In practice, based on the direction of the required locking ring's opening, the locking ring is welded into the constructed steel frame before the wall panel is prepared, and the wall panel is then prepared. According to the direction of the locking ring's opening, the required locking post holes are drilled, and the required square grooves are opened on the upper and lower end faces of the wall panel, as well as the required connecting grooves on the left and right end faces. The required locking connecting rods are then prepared and assembled. During installation, for example, after assembling the locking connecting rod in the connecting groove on one side of the wall, it is locked using the locking post. The wall is then locked to the outer frame using hook bolts. Another wall is then assembled on the other side of the locking connecting rod, locked again using the locking post, and then locked to the outer frame using hook bolts. This process of assembling and installing the walls makes the wall installation more convenient, efficient, and flexible, and further improves the locking stability between the walls.

[0055] The above description is merely a preferred embodiment of the invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
