The utility model comprises a decorative panel laid on the outer surface of the floor, the decorative panel is spliced on the outer surface of the floor through the first cement mortar layer, the first steel wire mesh is laid between the floor and the first cement mortar layer, the second A steel wire mesh is fixed on the floor with cement nails, a geogrid is laid between the decorative panel and the first cement mortar layer, a second cement mortar layer is arranged between the soil grid and the decorative panel, and a geogrid is laid between the decorative panel and the first cement mortar layer. The gaps between are filled with sealant. Compared with the prior art, when the original building structure is deformed, the steel wire mesh and the geogrid are properly stretched and shrunk to ensure that the cement mortar placed on it will not crack due to the deformation of the adjacent building structure floor.

Description

Decorative Expansion Joint Structure

technical field

The utility model relates to a building decoration structure, in particular to a structure for decorating expansion joints.

Background technique

In the construction industry, in order to prevent the structural cracks or damage of building components due to climate temperature changes (heat expansion, cold contraction), an expansion joint must be installed vertically at an appropriate position along the length of the building. The general expansion joint method In order to fill the concrete mortar at the joints, but it is easy to crack due to the deformation of the building, so that two seams are formed on the decorative surface, which affects the aesthetic effect of the decorative surface, the construction is complicated, and it is easy to cause water leakage.

Contents of the invention

The purpose of the utility model is to provide a decorative expansion joint structure, the technical problem to be solved is to prevent the expansion joint from cracking and the construction is simple.

In order to solve the above problems, the utility model adopts the following technical solutions: a decorative expansion joint structure, including a decorative panel laid on the outer surface of the floor, the decorative panel is spliced on the outer surface of the floor through the first cement mortar layer, the A first steel wire mesh is laid between the floor slab and the first cement mortar layer, the first steel wire mesh is fixed on the floor slab by cement nails, a geogrid is laid between the decorative panel and the first cement mortar layer, A second cement mortar layer is arranged between the grille and the decorative panel, and a sealant is filled in the gap between the decorative panels.

The gap between the decorative panels described in the utility model is provided with n-shaped caulking strips, and the gap between the n-shaped embedded strips and the decorative panels forms a filling cavity, and the sealant is filled in the filling cavity.

In the utility model, two adjacent steel wire meshes are connected to each other through the first n-shaped connecting piece.

Two adjacent geogrids of the utility model are connected to each other through the second n-shaped connecting piece.

Both the first n-shaped connector and the second n-shaped connector described in the utility model are made of stainless steel.

Compared with the prior art, the utility model adopts laying steel wire mesh and geogrid between the bottom of the decorative panel and the cement mortar layer, so that when the original building structure is deformed, the steel wire mesh and geogrid can be properly stretched and shrunk. , to ensure that the cement mortar set on it will not crack due to the deformation of the building structure floor; a U-shaped caulking strip is provided in the gap between the decorative panels, and a sealant is provided in the U-shaped caulking strip to make the expansion joint The structure plays a very good waterproof effect.

Detailed ways

The technical solutions of the present utility model will be further described in detail below in conjunction with the embodiments.

As shown in Figure 1, the decorative expansion joint system of the present utility model includes the floor 3 of the original building, and the floor 3 is provided with a steel wire mesh 1, and the steel mesh 1 is fixed on the floor 3 by cement nails. 1 are hooked to each other through the first n-shaped connecting piece 5 made of stainless steel material to prevent rust, and also to have a certain tension between the two steel wire mesh 1, and the first cement mortar is poured on the top of the steel wire mesh 1 layer 4, the pouring thickness of the first cement mortar layer 4 is 20 mm, after the first cement mortar layer 4 is poured, the geogrid 6 is laid, and the second n-shaped connector is passed between two adjacent soil common grids 6 5 hang each other to form a whole, pour the second cement mortar layer 7, the thickness of the second cement mortar layer 7 is 10mm, lay the decorative panel 2 on the second cement mortar layer 7, the decorative panel 2 is a stone veneer, An n-shaped caulking strip 9 is embedded in the gap between the two decorative panels 6 , and a filling cavity is formed between the n-shaped caulking strip 9 and the gap between the two decorative panels 6 , and a sealant 8 is injected into the filling cavity.

The utility model makes the cement mortar not easy to crack and durable through the expandable force and contraction of the geogrid and the steel wire mesh.
