However, the existing steam-pressurized concrete panels are usually connected by a relatively simple structure to merge two concrete panels together, and the joint position usually needs to be sealed and fixed with mud. The existing method is generally to scrape mud on the joint position before joining. In the joint process, there will be mud waste and accidental separation of mud, and the operation is relatively troublesome. Utility Model Content

[0023] See also Figure 1-3As shown, the utility model is a self-insulating autoclaved aerated concrete board, comprising a precast concrete board 1, and a bonding structure 2 is arranged at the butt joint of two precast concrete boards 1.

The wall panel 101 is fixedly connected with a butt joint protrusion 1012 at the center position on the opposite side of the butt joint groove 1011, and the structure of the butt joint protrusion 1012 is the same as the groove type of the butt joint groove 1011.

[0025] The adhesion structure 2 includes a covering bag 201, which has the same shape as the arc-shaped groove of the flat-joint groove 1011 and is bonded and fixed to the inside of the arc-shaped groove of the flat-joint groove 1011 in the form of a convex surface facing the groove. The inside of the covering bag 201 is provided with a plurality of storage cavities of the same shape from top to bottom, and the inside of the storage cavity is fixedly connected with mud 2011. The storage cavity inside the covering bag 201 is thinner toward the arc surface and the surface opposite to the arc surface, and thicker at the two corners. A diagonal channel is provided in the middle position inside the arc membrane of the covering bag 201 and the membrane opposite to the arc membrane, and the upper and lower ends of the channel are intersected and then pass through the covering bag 201, and the inside of the channel is fixedly connected with a bag-breaking lead 2012 according to the path, and the bag-breaking lead 2012 can meet the needs of expansion and extension.

[0026] During operation, firstly, a wall panel is assembled to the designated position according to the plan, with the side with the flat joint groove 1011 facing outwards, and then the wall panel is positioned using the support structure. After being fixed, another wall panel can be moved to the position of the second wall panel, and the second wall panel is adjusted so that the side with the flat joint protrusion 1012 faces the side of the flat joint groove 1011 of the first wall panel, and the second wall panel is stably moved so that the flat joint protrusion 1012 of the second wall panel faces the inside of the flat joint groove 1011. During the facing process, the flat joint protrusion 1012 of the second wall panel will squeeze the covering bag 201 and the bag breaking lead 2012, so that they are moved along the flat joint groove 101 1 extends to the open gap on both sides until the corners on both sides of the covering bag 201 are exposed at the gap, and then the second wall panel is positioned by the supporting structure, and then the position of the extended bag-breaking lead 2012 is found, and the bag-breaking lead 2012 is ignited to break the sealed covering bag 201, and the ignited covering bag 201 will break and shrink to both sides at the ignition position. At this time, the mud stored inside will contact the wall surface, and then the second wall panel can be pushed and pressed, and the corners of the covering bag 201 are appropriately pulled to pull the covering bag 201 out of the wall gap, and then the wall gap is further repaired, so as to complete the mud sealing treatment between the wall panels.
