Background

In order to protect land resources and ecological environment, building energy-saving materials are pushed, along with the development of science and technology, building materials are changing day by day, wall materials are reformed all over the country, novel substituted wall materials are searched, various wall materials are continuously updated and popularized, a large amount of novel building materials are produced and are favored by people, and the building energy-saving materials are particularly popular in the fields of filling walls, non-bearing partition walls, old house reconstruction and the like of buildings. The autoclaved lightweight aerated concrete slab has the excellent characteristics of light weight, high plasticity, strong shock resistance, good adaptability, good waterproof property, good sound insulation effect and the like, and in addition, the wallboard has the advantages of smooth surface, accurate size, easy forming, convenient production and high production efficiency; the integrity is good, the assembly type installation can be carried out, the construction efficiency is high, and therefore the autoclaved aerated concrete slab occupies an important position in the construction project. However, the crack easily appears in the splicing seam of the autoclaved aerated concrete slab, which is a technical problem troubling the wall construction.

The autoclaved aerated concrete slab adopts butt joint seams of a male groove and a female groove, and the grid cloth arranged at the joint seams to hang anti-crack mortar can enable the originally planar autoclaved aerated slab to be protruded at the joint seams, so that the leveling is performed again during later decoration, and a large amount of materials are wasted.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a save artifical, save material, reduce machinery and use, accelerate the novel aerated concrete slab that evaporates of concatenation seam of construction progress.

The utility model adopts the technical proposal that:

a novel autoclaved aerated concrete slab with splicing seams comprises a slab body, wherein the slab body is a Z-shaped slab body, every two Z-shaped slab bodies are spliced with each other, splicing seams along the outline of the Z-shaped slab body are arranged at the splicing surfaces, two arc-shaped grooves are formed in the splicing surface of a first Z-shaped slab body, first step grooves are formed in two corner positions, a first connecting concave table used for filling mortar is further arranged on the splicing surface of the first Z-shaped slab body, and the first connecting concave table is excessively connected with the two arc-shaped grooves through an arc;

the splicing surface of the second Z-shaped plate body is provided with two circular-arc-shaped bosses matched with the circular-arc-shaped grooves, two corner positions are provided with second stepped grooves symmetrical to the first stepped grooves, the splicing surface of the second Z-shaped plate body is also provided with second connecting concave tables corresponding to the first connecting concave tables, and the second connecting concave tables are connected with the two circular-arc-shaped bosses through circular arc transition;

the first stepped groove and the second stepped groove form a splayed mortar groove, the first stepped groove and the second stepped groove respectively comprise an inclined plane, a vertical plane and a horizontal plane which are sequentially connected, and the horizontal plane is connected with the splayed mortar groove.

Furthermore, the thickness of the first connecting concave table and the thickness of the second connecting concave table are both one half of the thickness of the Z-shaped plate body, the first connecting concave table is formed by sinking one half of the front surface of the first Z-shaped plate body, the second connecting concave table is formed by sinking one half of the back surface of the second Z-shaped plate body, and grooves are formed in the front surfaces and the back surfaces of the first connecting concave table and the second connecting concave table.

Compared with the prior art the beneficial effects of the utility model:

1. the utility model adopts the Z-shaped plate body, so that the mutual splicing of every two plate bodies is more reliable;

2. the utility model is provided with the arc-shaped groove and the arc-shaped boss, which increases the contact area of the two plates, and compared with the square groove, the embedded mortar is easier to flow, so that the mortar is more compact, and meanwhile, the anti-crack mortar is plastered and pressed for multiple times in a layered way, thereby avoiding the situation that the shrinkage of the anti-crack mortar is larger in one-time construction, and the crack is caused by the self shrinkage of the anti-crack mortar, so that the crack is found in the splicing joint;

3. the utility model is also provided with connecting concave platforms at the splicing seams, one is positioned at the front side and the other is positioned at the reverse side, and mortar is filled on the connecting convex platforms, so that the Z-shaped plate bodies are more closely connected;

4. the utility model discloses a two bight positions are provided with the ladder groove, and two liang of concatenation ladder grooves of Z template body constitute eight characters mouth mortar recesses, adopt net cloth to wipe and press and anti-crack mortar back of making level in the ladder groove, and whole face is still at a plane, can not influence the basic unit's roughness that the later stage fitment required.
