Problems solved by technology

However, this method not only has high technical requirements for construction workers, but also the phenomenon that the organic glue loses its sealing and waterproof function due to insufficient filling is prone to occur during the construction process, and because the organic glue is easy to age, its brittleness will increase with time. As it increases, the service life is short and the later maintenance is complicated
In addition, because the entire seam is filled with a large amount of organic glue, the construction cost of the project is greatly increased

Embodiment 1

[0037] This embodiment provides a method for treating the joints of an autoclaved aerated concrete exterior wall panel, the method comprising the following steps:

[0038] S0, such as figure 1 As shown, grooves 1-3 are provided on the side wall of one of the autoclaved aerated concrete outer wall panels 1 along its length direction in advance to form the second autoclaved aerated concrete outer wall panel 1 to be spliced. A splicing surface 1-1; on the side wall of another autoclaved aerated concrete exterior wall panel 1, a protrusion 1-4 for clamping with the groove 1-3 is provided to form a second splicing surface 1-2 . The advantage of such setting is: on the one hand, the curved surface of the groove 1-3 and the protrusion 1-4 can be used to extend the path of moisture migration along the thickness direction of the autoclaved aerated concrete exterior wall panel 1, thereby slowing down the moisture migration On the other hand, when splicing, the construction personnel o...

Embodiment 2

[0049] The steps and principles of the method for treating the joints of the autoclaved aerated concrete exterior wall panels in this embodiment are the same as those in Embodiment 1, and will not be repeated in this embodiment.

[0050] The difference is that there are multiple grooves 1-3 in this embodiment, and the multiple grooves 1-3 are sequentially arranged along the thickness direction of the autoclaved aerated concrete exterior wall panel 1 . Since the protrusions 1-4 are arranged in one-to-one correspondence with the grooves 1-3, the number of the protrusions 1-4 is the same as that of the grooves 1-3, and it is also along the thickness direction of the corresponding autoclaved aerated concrete exterior wall panel 1 Set in turn.

[0051] For example, if Figure 4 As shown, two grooves 1-3 are opened on the side wall of one of the autoclaved aerated concrete outer wall panels 1, and two protrusions 1 are opened on the side wall of the other autoclaved aerated concret...

Abstract

The invention relates to the field of building materials, and provides a plate joint treatment method for autoclaved aerated concrete external wall plates. The plate joint treatment method comprises the following steps that S1, plate joint shoving materials are brushed at the first end of a first spliced face of one of the autoclaved aerated concrete external wall plates and / or the first end of asecond spliced face of the other autoclaved aerated concrete external wall plate; S2, the first spliced face and the second spliced face are moved oppositely until the space between the first end of the first spliced face and the first end of the second spliced face is filled with the plate joint shoving materials, and a gap is formed between the second end of the first spliced face and the secondend of the second spliced face; S3, a plate joint between the outer walls of the two autoclaved aerated concrete external wall plates is cleared; and S4, the plate joint between the outer walls of the two autoclaved aerated concrete external wall plates is filled with a sealing adhesive. According to the plate joint treatment method, the using amount of the sealing adhesive can be reduced, and the problem that the sealing adhesive is prone to uncompacted filling is avoided; and in addition, the gap between the second end of the first spliced face and the second end of the second spliced facecan further be utilized to further block transferring of moisture.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a board seam treatment method for an autoclaved aerated concrete exterior wall board. Background technique [0002] With the country's vigorous promotion of prefabricated buildings, various prefabricated supporting wall panel technologies have developed rapidly. Autoclaved aerated concrete (Autoclaved Lightweight Concrete, ALC) wall panels can be used as internal Partition walls, floor slabs and facade panels. Among them, ALC wall panels, as exterior wall panels, are considered to be the main supporting external protection parts of steel structure buildings. Convenient, durable and so on. [0003] Since the ALC wall panel is used as an assembled steel structure exterior wall panel, the splicing joint between two adjacent autoclaved aerated concrete exterior wall panels is a through joint, and the treatment method of the panel seam during use must adapt to the interlayer displa...
