Description

Technical Field

[0001] The utility model belongs to the technical field of building plastering construction, and in particular relates to a double-sided mixed mortar plastering anti-cracking structure for a filling wall. Background Art

[0002] The plastering (plastering) of the infill wall masonry is a basic process in building decoration and renovation. It is the base surface layer that carries a large number of decorative effects. The quality of the plastering (plastering) construction has an important influence on the decorative molding effect.

[0003] Since the infill wall masonry mostly adopts sintered hollow bricks, sintered porous bricks, autoclaved aerated concrete blocks, lightweight aggregate concrete small hollow blocks, etc., the relative moisture content and roughness of the masonry vary greatly. The water absorption rate and shrinkage deformation of the infill wall after plastering are uneven, which can easily cause common quality problems such as hollowing and cracking of the plaster surface. In particular, the potential risk of cracking is greater for medium and high-level plastering with a thickness of more than 30 mm, so targeted anti-cracking structural measures are needed. Utility Model Content

[0004] The utility model aims to provide a double-sided mixed mortar plastering anti-cracking structure for a filling wall, thereby solving the problem of cracking of the filling wall plastering.

[0009] Furthermore, the mixed mortar has a surface strength of at least M5 and a thickness of 25 to 35 mm.

[0010] Furthermore, the tensioning steel wire is galvanized steel wire, and the steel wire mesh is galvanized steel wire mesh.

[0011] Furthermore, the tensioning steel wires are arranged in a plum blossom shape.

[0013] Furthermore, both ends of the tensioning steel wire are bent and tied sections, and the bent and tied sections are anchored to the wire mesh.

[0014] Furthermore, the bending and tying section is an L-shaped structure.

[0015] Furthermore, the steel wire mesh is a corrugated steel wire mesh.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a schematic diagram of the structure of the utility model.

[0019] In the figure: 1- masonry filling wall, 2- mixed mortar plastering, 3- tensioning steel wire, 4- steel wire mesh. DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0021] refer to Figure 1 As shown, a double-sided mixed mortar plastering anti-cracking structure of a filling wall includes a masonry filling wall 1, a mixed mortar plastering 2, tensioning steel wires 3 and a steel wire mesh 4.

[0022] The masonry filling wall 1 is a wall structure built with sintered hollow bricks, sintered porous bricks, autoclaved aerated concrete blocks or small hollow blocks of lightweight aggregate concrete, and plays the role of enclosure and separation.

[0023] Both sides of the masonry filling wall 1 are provided with mixed mortar plastering 2, which serves as a decoration. The mixed mortar plastering 2 has a strength of at least M5 and a thickness of 25 to 35 mm (preferably 30 mm). Specifically, the mixed mortar plastering 2 includes a 10 to 15 mm thick mixed mortar bottom ash layer on the inner side and a 15 to 20 mm thick mixed mortar top ash layer on the outer side. The steel wire mesh 4 is located between the mixed mortar bottom ash layer and the mixed mortar top ash layer to achieve step-by-step construction.

[0024] A tensioning steel wire 3 is inserted into the masonry filling wall 1, and both ends of the tensioning steel wire 3 extend into the mixed mortar plastering 2 on both sides, and it is ensured that the ends of the tensioning steel wire 3 do not pass through the mixed mortar plastering 2. The tensioning steel wire 3 is used to fix the steel mesh on both sides, and the tensioning of both ends is conducive to reducing the burden of the steel mesh on the wall on one side. A steel mesh 4 is provided in the mixed mortar plastering 2, and the tensioning steel wire 3 is connected to the steel mesh 4.

[0025] The tension wire 3 is No. 10 galvanized steel wire, arranged in a plum blossom shape with a spacing of 600mm, to ensure uniform and reliable effect on the wire mesh. The length of the tension wire 3 is the wall thickness and 25 to 35mm (preferably 30mm) is added at both ends, leaving a portion for bending and knotting at the end. The two ends of the tension wire 3 are L-shaped bending and knotting sections, which are anchored to the wire mesh 4, and have better firmness and anti-slip effect than simple binding and attachment.

[0026] The steel wire mesh 4 is a galvanized corrugated steel wire mesh, which can improve the wrapping effect of the plastering on the outer side of the wall and reduce or avoid subsequent cracking problems.

[0027] The workflow of this utility model:

[0028] Punch holes in the clean, tidy, and sharp-free masonry filling wall and apply No. 10 galvanized steel wire, or bury it as the masonry filling wall is constructed. For sintered hollow bricks and small hollow masonry filling walls made of lightweight aggregate concrete with high water absorption, water (spray) them 1-2 days in advance. Apply a 10-15mm M5 strength mixed mortar base ash leveling layer to the masonry filling wall, spread a galvanized steel wire mesh and bend and anchor it with the pre-buried No. 10 galvanized steel wire, apply a 15-20mm mixed mortar top ash layer, and the surface should be smooth and clean, without smearing marks, hollows, and cracks, to achieve a decorative plastering effect.

[0029] The comprehensive structural measures taken can effectively meet the bonding and anti-cracking structure of 30mm thick medium and high-grade plaster surfaces, meet the functional requirements and ensure construction quality.

[0030] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
