ALC panel walls (autoclaved lightweight aerated concrete partition walls) have the advantages of fast construction speed and low cost, can meet the needs of urban construction, and promote urban development. However, in actual engineering applications, there are wall cracking phenomena. Especially after the delivery of the bare concrete houses, the small property owners carried out secondary fine decoration, damaging the steel wire mesh (or fiberglass mesh) at the joints of the ALC panel walls, resulting in wall cracking in the later stage of fine decoration. This phenomenon has received extensive attention in the construction industry. Summary of the Invention

Before pouring the structural columns, the reserved holes are grouted, which greatly enhances the overall performance of the ALC panel walls, effectively prevents the occurrence of wall cracking in the later stage, and at the same time plays an anti-overturning effect.

[0029] The following non-limiting embodiments are used to illustrate the present application.

[0030] Embodiment 1

[0031] Referring to Figure 1 and Figure 2 shown, a construction structure for preventing cracking of an ALC slab wall includes an upper member 1, a lower member 2, an ALC slab wall 3, horizontal reserved holes 4, reinforcing bars 5, filling mortar 6 and a construction column 7.

[0032] The upper member 1 and the lower member 2 are completed building structures. There are several ALC slab walls 3 between the upper member 1 and the lower member 2. The ALC slab wall 3 is used as a partition wall to divide the space, and has the advantages of light weight, good fire prevention performance, sound insulation performance, environmental protection, economy, and convenient construction.

[0033] There are several layers of horizontal reserved holes 4 on the ALC slab wall 3. The horizontal reserved holes 4 are used to realize the threading and placement of the reinforcing bars 5. The reinforcing bars 5 are horizontally threaded through the horizontal reserved holes 4 and fixed by the filling mortar 6. The ALC slab wall 3 is structurally strengthened by the reinforcing bars 5, and the ALC slab wall 3 is connected to the construction column as a whole to improve the structural integrity.

[0034] There is also a construction column 7 between the upper member 1 and the lower member 2. The construction column 7 is used for the load-bearing transition between the upper and lower members. At the same time, the reinforcing bars 5 are poured into the construction column 7, so that the ALC slab wall and the construction column form a whole, thereby improving the structural strength of the ALC wall, preventing the occurrence of subsequent wall cracking, and at the same time playing an anti-overturning effect.

[0035] The upper member 1 is the upper beam-slab, and the lower member 2 is the lower beam-slab. The upper beam-slab and the lower beam-slab are exposed beams. Similarly, the upper beam-slab and the lower beam-slab can also be concealed beams or floor slabs.

[0036] The ALC panel wall 3 is arranged in a single layer, that is, only one layer of ALC panel wall 3 is arranged between the upper member 1 and the lower member 2. Similarly, according to different requirements, the ALC panel wall can also be arranged in a double layer or multiple layers, which adds the joint treatment between the upper and lower layer panel walls.

[0037] At least two ALC panel walls 3 are arranged between two adjacent construction columns 7, that is, the reinforcing bars 5 connecting and fixing between two adjacent construction columns 7 act on multiple ALC panel walls 3. In this embodiment, four ALC panel walls 3 are arranged between two adjacent construction columns 7.

[0038] The horizontal reserved hole 4 is a rectangular cross-section hole, preferably a rectangular hole with a size of 30mm×80mm, which is convenient for processing and manufacturing, is also beneficial to the horizontal penetration of the reinforcing bar 5, and can slightly adjust the horizontal and vertical positions of the reinforcing bar 5. The middle distance between the upper and lower layer rectangular holes is 500mm, and the distance between the rectangular hole and the upper and lower ends of the wall panel is ≦250mm.

[0039] Both ends of the reinforcing bar 5 (φ6.5mm) extend into two adjacent construction columns 7 respectively, that is, a single section of reinforcing bar 5 is only arranged on two adjacent construction columns 7 and the ALC panel wall 3 therebetween, which is convenient for the processing and manufacturing of the reinforcing bar 5, convenient for installation construction at the same time, and can also ensure the integral connection effect.

[0040] The filling mortar 6 is a slightly expanding cement mortar, which realizes the plugging of the horizontal reserved hole 4 and the fixed placement of the reinforcing bar 5, so as to fix the reinforcing bar 5 on the ALC panel wall 3 and realize the force transmission between the two.

[0041] The construction column 7 is a reinforced concrete structure, which has good structural strength and realizes the load-bearing force up and down. The reinforcing bar 5 is poured inside the construction column 7 to realize the fixed connection between the two and ensure the force transmission. The reinforcing bar 5 can also be tied and fixed on the steel bar skeleton of the construction column 7 to further improve the integrity.

[0042] Embodiment 2

[0043] Reference Figure 1 and Figure 2 As shown, a construction method for preventing cracking of ALC panel walls is used to form the construction structure for preventing cracking of ALC panel walls in Embodiment 1.

[0044] Specifically, it includes the following steps: Step S01, installation of the panel wall: Install and fix several ALC panel walls 3 between the upper member 1 and the lower member 2, and reserve the construction position of the construction column between the upper member 1 and the lower member 2.

[0045] When the ALC slab wall is produced, a rectangular hole with a size of 30mm×80mm is reserved in the middle to facilitate the smooth passing of the wall tie bars during on-site installation. The middle distance between the upper and lower rectangular holes is 500mm, and the distance between the rectangular hole and the upper and lower ends of the wall panel is ≤250mm, ensuring the uniform and reliable action of the reinforcing bar 5.

[0046] The distance for setting the structural columns is generally 3000mm - 4000mm (the specific setting needs to be carried out according to the requirements of the corresponding specifications).

[0047] Step S02, inserting the reinforcing bar: After the ALC slab wall (between two structural columns) is installed and fixed, insert the reinforcing bar 5 (φ6.5mm) into the horizontal reserved hole 4 of the ALC slab wall 3, and at the same time, the reinforcing bar 5 passes through the construction position of the structural column, and the steel bar needs to be anchored in the two end structural columns.

[0048] In step S02, both ends of the reinforcing bar 5 extend into the two adjacent structural columns 7 respectively.

[0049] Step S03, closing the reserved hole: Use the filling mortar 6 to fill and close the horizontal reserved hole 4, and fix the reinforcing bar 5 on the ALC slab wall 3. The filling mortar 6 uses micro-expansion cement mortar or the professional mortar supporting the ALC slab wall.

[0050] Step S04, pouring the structural column: Bind and place the steel bar framework of the structural column, install the formwork at the construction position of the structural column to form a closed pouring space, and pour concrete in the pouring space to form the structural column 7.

[0051] Step S05, removing the formwork and curing: Remove the formwork of the structural column and sprinkle water for curing the structural column.

[0052] The foregoing basic example of the present application and its various further selected examples can be freely combined to form multiple embodiments, all of which are the embodiments that can be adopted and claimed in the present application. In the solution of the present application, each selected example can be arbitrarily combined with any basic example and selected example.

[0053] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
