Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to an autoclaved aerated concrete integrated wall structure. Background Art

[0002] At present, the integrated insulation structure wall has been widely used in the building exterior wall industry. It has significantly improved the quality and safety problems of the traditional exterior wall system with thermal insulation materials attached to the wall, such as the easy cracking, water seepage and falling off of the insulation layer. It also has the obvious advantages of convenient construction, environmental protection and energy saving.

[0003] The existing thermal insulation structure integrated wall still has some shortcomings in engineering practice. The utility model patent with the authorization announcement number CN206521847U discloses an autoclaved aerated concrete integrated wall structure assembled thermal insulation decoration integrated wall, which includes a cement fiberboard and an insulation board. The upper and lower sides of the insulation board are connected to the cement fiberboard. The thermal insulation board in the thermal insulation decoration integrated wall extends to the left to form a convex groove. The two cement fiberboards in the thermal insulation decoration integrated wall extend to the right to form a groove. The length of the thermal insulation board extending to the left is equal to the length of the two cement fiberboards extending to the right. The convex groove of one wall is inserted into the groove of the other wall for splicing. During the installation process, the thermal insulation layer between the two walls can be tightly spliced, which ensures the thermal insulation effect and enhances the firmness of the wall.

[0004] In this patented technical solution, cement fiberboard as internal and external wallboard will greatly increase the wall density and significantly increase the construction cost, which limits the application scenarios. At the same time, in this solution, the wall only forms a set of concave and convex groove assembly structures at the left and right ends, that is, the two walls are only spliced ​​and assembled in the left and right directions, which is not enough to ensure the assembly strength and thermal insulation effect of the wall.

[0005] Based on this, developing a new type of autoclaved aerated concrete integrated wall structure for application in engineering practice is an urgent problem to be solved. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] like Figure 1-5As shown, an autoclaved aerated concrete integrated wall structure includes an inner wall panel 1 and an outer wall panel 2, wherein an insulation board 3 is fixedly connected between the inner wall panel 1 and the outer wall panel 2 to form an integrated wall structure. In order to facilitate the assembly of the integrated wall, the insulation board 3 is staggered relative to the inner wall panel 1 and the outer wall panel 2, so that the front end and the lower end of the insulation board 3 protrude from the front end and the lower end of the inner wall panel 1 and the outer wall panel 2, respectively, to form a convex structure 41 for wall assembly. At the same time, the top and the right end of the insulation board 3 are respectively recessed in the top and the right end of the inner wall panel 1 and the outer wall panel 2, serving as a recessed structure 42 for wall assembly, and finally an integrated wall having a concave-convex assembly structure on all four sides is formed.

[0030] like Figure 1 , 2 As shown, during construction and assembly, the convex structure 41 of the integrated wall is tightly plugged into the concave structure 42 of another wall, so that the four sides of the wall are firmly clamped through the concave and convex assembly structure. Compared with the traditional two-sided clamping structure, the construction accuracy and assembly strength of the wall are greatly improved, the air tightness of the wall is increased, and the moisture-proof, noise-reduction and thermal insulation properties of the wall are improved.

[0031] As a preferred embodiment, the inner wall panels 1 and the outer wall panels 2 can be made of autoclaved aerated concrete to overcome the problems of existing cement fiberboards as inner and outer wall panels, such as large wall volume, high cost, and limited application scenarios. Autoclaved aerated concrete has high strength and controllable dry density index, which reduces the wall volume, and can obtain high-strength, lightweight integrated wall materials. In addition, the wall panels made of autoclaved aerated concrete have low cost and mature construction node solutions, which can meet various installation methods such as embedded, semi-embedded, and external, and can be widely used in apartments, businesses, hotels, and other places with steel and concrete structures.

[0032] Preferably, the insulation board 3 can be selected from existing insulation materials according to construction requirements, such as extruded board, graphite extruded board, polystyrene board, graphite polystyrene board, rock wool board, polyurethane board, etc., to meet different construction requirements. The insulation board 3 is connected to the inner wall board 1 and the outer wall board 2 by mortar or adhesive.

[0033] Furthermore, if Figure 3-5As shown, the inner wall panel 1, the insulation panel 3 and the outer wall panel 2 are connected and fixed by a connector 5 to form a firm integrated wall structure. The connector 5 includes an embedded rod 51 and a fastening sleeve 52. The embedded rod 51 and the fastening sleeve 52 are threadedly connected to fix the inner wall panel 1, the insulation panel 3 and the outer wall panel 2 into an integrated wall structure. Specifically, the tail end of the embedded rod 51 is fixedly set in the outer wall panel 2, and the top end of the embedded rod 51 extends out of the end face of the outer wall panel 2. The insulation panel 3 and the inner wall panel 1 are provided with a connecting hole 6 corresponding to the embedded rod 51, and the tail end of the fastening sleeve 52 is provided with a limit stop 53, and the connecting hole 6 on the inner wall panel 1 is provided with a countersunk hole 61 corresponding to the limit stop 53.

[0034] When connecting, the embedded rod 51 extending from the exterior wall panel 2 is passed through the connection holes 6 on the insulation board 3 and the interior wall panel 1 in turn, and the insulation board 3 and the interior wall panel 1 are laid on the exterior wall panel 2. Then, the fastening sleeve 52 is inserted through the connection hole 6 on the interior wall panel 1 and screwed onto the embedded rod 51, so that the limit stop 53 is fixed at the bottom of the countersunk hole 61, and the interior wall panel 1, the insulation board 3 and the exterior wall panel 2 are fixedly connected. After the connection is completed, the filling material 54 such as mortar or sealant is poured into the connection hole 6 of the interior wall panel 1 to ensure the connection strength and thermal insulation performance. The connector 5 provided in this embodiment facilitates the connection and fixation between the wall panel layers, improves the working efficiency, and ensures the connection strength.

[0035] Furthermore, if Figure 4 As shown, the tail end of the embedded rod 51 is provided with a reinforcing barb 55, which is used to strengthen the connection strength between the embedded rod 51 and the outer wall panel 2. The reinforcing barb 55 is a plurality of barb structures fixedly connected to the tail end of the embedded rod 51, and the plurality of barb structures are staggered. The setting of the reinforcing barb 55 effectively enhances the firmness of the connection between the embedded rod 51 and the outer wall panel 2, and avoids the situation where the embedded rod 51 falls out of the outer wall panel 2. The connection strength between the wall panels is further guaranteed. In order to avoid the generation of cold bridges, the embedded rod 51 does not penetrate the outer wall panel 2, and the end of the embedded rod 51 stops in the outer wall panel 2 to ensure the thermal insulation performance of the wall.

[0036] Thanks to the higher connection strength of the connecting piece 5, the number of connecting pieces 5 in the utility model can be controlled at 4-8 per square meter. The use of fewer connecting pieces 5 reduces the cost of wall manufacturing on the one hand, and reduces the number of connecting holes 6 on the wall on the other hand, thereby ensuring the structural strength and thermal insulation performance of the wall.

[0037] Preferably, if Figure 2As shown, the edges and corners of the exterior wall panels 2 and the interior wall panels 1 are provided with chamfer structures 7 to reduce the damage caused by the edges and corners during production and transportation, resulting in defects such as notches and debris. At the same time, the setting of the chamfer structure 7 provides a sealing construction space at the joints during wall assembly, which is convenient for construction workers to inject sealant into the triangular groove formed by the chamfer structure 7, ensuring the sealing construction effect.

[0038] Furthermore, if Figure 5 As shown, the outer side of the exterior wall panel 2 is provided with an anti-crack plastering layer 8 for improving the anti-crack performance of the wall. The anti-crack surface layer can be in the form of a structure in which anti-crack mortar is pressed into an alkali-resistant mesh cloth. The inner side of the interior wall panel 1 is also provided with an interior decoration layer 9, and the interior decoration layer 9 can be painted or brick-finished to form an integrated wall with an interior decoration surface. The provision of the anti-crack plastering layer 8 and the interior decoration layer 9 improves the integration of the wall, which can be customized according to the needs of building use, processed and formed in the factory at one time, and then transported to the project site for installation. The construction period is shortened and the construction waste at the construction site is reduced.

[0039] The above disclosure is only a specific embodiment of the present patent, but the present patent is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, the deformation made should be deemed to belong to the protection of the present invention.
