Background

At present, plastering engineering refers to a system construction process of smearing plastering mortar on the surface of a substrate material, having the functions of protecting a base layer and improving the appearance and providing special functions for buildings. The plastering engineering has two major functions: the wall has the advantages that firstly, the wall is protected from being eroded by wind, rain and snow, the moistureproof, weatherproof and heat insulation capabilities of the wall are improved, and the durability and thermal performance of the wall are improved; and secondly, the functions of beautifying, improving indoor sanitary conditions, purifying air, beautifying the environment and improving the living comfort level are realized.

For house construction, the forming quality of wall plastering attracts more and more attention of all parties, but the traditional building wall surface bottom layer plastering method is to use a trowel for bricklayer to plaster the bottom layer of the wall surface, the wall surface is often required to be repeatedly plastered with the bottom layer for many times, the one-step forming cannot be realized, the process cost is high, the construction time is long, the quality cannot be ensured, and the conditions of plastering bottom layer falling crack and wall body crack after the whole plastering is finished often caused.

CN205444825U discloses a plastering and slurry throwing device, which comprises a handle and an operation net, wherein the operation net is fixed on the upper part of the handle through a binding wire; the operation net is formed by transversely and longitudinally folding wire nets in a staggered mode, and the thickness of the operation net is 10-15 mm. Above-mentioned plastering gets rid of thick liquid device, the operation net is intensive, and is violently indulged crisscross, has improved the thick liquid ability of inhaling of operation net, effectively guarantees operating efficiency and engineering construction quality.

However, the crack prevention member formed of the mesh-like net disposed on the bottom layer is attached to the surface of cement mortar or lightweight aerated concrete, and thus cannot completely endure thermal deformation and mechanical deformation due to inherent characteristics of concrete, so that the generation of cracks cannot be perfectly prevented.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can slow down house building wall that plastering layer warp and plaster and prevent structure of ftractureing, its technical scheme as follows:

the plastering anti-cracking structure for the wall surface of the residential building comprises a bottom layer, wherein a circular chain embedded along the width direction is embedded in the surface of the bottom layer, at least one half part of the circular chain is immersed in the bottom layer, and the rest part of the circular chain is exposed out of the bottom layer and embedded in a plastering layer.

Preferably, the circular chain is formed by alternately sleeving a flat ring tiled on the surface of the bottom layer and a vertical ring vertically inserted on the surface of the bottom layer, at least one half of the vertical ring is immersed in the bottom layer, and the rest part of the vertical ring is exposed outside the bottom layer and is embedded in the plastering layer.

Preferably, the circular chain is formed by alternately sleeving a first inclined ring forming an included angle of 30-60 degrees with the surface of the bottom layer and a second inclined ring forming an included angle of 120-150 degrees with the surface of the bottom layer, and the intersection point position of the first inclined ring and the second inclined ring is immersed in the bottom layer.

Preferably, the ring section of the ring chain comprises a waist-shaped ring main body, two ends of the ring main body are provided with a notch positioned in the center, the width of the notch is smaller than the diameter of the edge of the ring main body, and a C-shaped ring in a shape of a major arc is bridged between the edges of the two sides of the notch.

Preferably, the diameter of the edge line of the circular chain is 0.14mm-0.22 mm.

The utility model has the advantages that:

the utility model discloses utilize the ring chain when tiling, still have the part can not paste the characteristics on the plane, regard the ring chain as the splice bar between plastering layer and the bottom to because of the ring chain has unsettled part outside the bottom, so the ring chain can form effective stable connection between bottom and plastering layer, avoids the plastering layer to appear weighing down and splits and spider crackle.

Detailed Description

Example 1:

referring to fig. 1, a schematic view of the plastering anti-cracking structure of the wall surface of the residential building of the embodiment is shown, and the concrete structure is as follows: mainly comprises a bottom layer 101, a circular chain 102 and a plastering layer 103 in sequence. The surface of the bottom layer 101 is embedded with a ring chain 102 embedded along the width direction, at least one half part of the ring chain 102 is immersed in the bottom layer 101, and the rest part is exposed outside the bottom layer 101 and embedded in the plastering layer 103. The circular ring chain 102 is formed by alternately sleeving a flat ring 121 laid on the surface of the bottom layer 101 and a vertical ring 122 vertically inserted on the surface of the bottom layer 101, at least one half of the vertical ring 122 is immersed in the bottom layer 101, and the rest part of the vertical ring 122 is exposed out of the bottom layer 101 and is embedded in the plastering layer 103.

Referring to fig. 2, the ring segment of the ring chain 102 includes a waist-shaped ring main body 123, two ends of the ring main body 123 are provided with a central gap, the width of the gap is smaller than the diameter of an edge of the ring main body 123, and a C-shaped ring 124 having a good arc shape is bridged between two side edges of the gap. The diameter of the edge line of the circular chain 102 is 0.14mm-0.22 mm.

When the circular chain type plastering machine is used, when the bottom layer 101 is constructed, the circular chain 102 is embedded in the surface of the bottom layer 101 in a parallel or criss-cross mode, after the bottom layer 101 is hardened, the surface of the bottom layer 101 is coated with the plastering layer 103, the plastering layer 103 needs to completely cover the circular chain 102, and the thinnest part of the plastering layer 103 cannot be less than 1 mm.
