Description

TECHNICAL FIELD

[0001] The utility model relates to a beating tool, in particular to a beating tool for wall plastering base suitable for use in a limited space. BACKGROUND

[0002] In recent years, the problem of wall skin peeling caused by wall hollowing has gradually become one of the common problems of construction engineering quality. In order to effectively curb the hollowing phenomenon in plastering engineering, the treatment process of the plastering base needs to be innovated and optimized.

[0003] In the prior art, the common base treatment method is "spraying", and the slurry is P.O 42.5 cement, sand and glue which are proportioned, and after proportioning, the slurry is sprayed on the wall to be plastered by using an air compressor, the formed burrs should be uniformly arranged in point shape, the burr height is preferably 3-5mm, after curing, the burrs reach a certain strength (as a standard that the hand cannot be broken) to perform plastering construction, thereby increasing the adhesion of the plastering layer and the base wall.

[0004] The spraying technology has found many problems in actual engineering practice. Due to various reasons in the construction process, such as air compressor pressure inconsistency, uneven spraying time of the spray gun, different distances between the spray gun and the wall, etc., the burrs formed by spraying are not prominent, different in size, and uneven in spacing, and the forming quality of the burrs formed by spraying cannot be controlled, and the adhesion of the plastering layer and the base wall cannot be guaranteed.

[0005] Through comparative analysis of actual engineering application, compared with the traditional mechanical spraying technology, the wall base beating and brushing technology can significantly reduce the hollowing rate of the plastered wall, and becomes a more efficient treatment method. The beating and brushing process can greatly avoid the quality problems of the plastering layer such as hollowing and cracking caused by improper base treatment, thereby significantly reducing the hollowing rate and greatly improving the quality level of the plastering engineering. With the reduction of repair times, not only the maintenance cost can be effectively reduced, but also the complaint rate of the owner can be greatly reduced, and the living satisfaction of the home buyer is effectively improved. Although the beating and brushing process is slightly compact in construction period and the labor cost is slightly high compared with the mechanical spraying technology, considering the excellent hollowing prevention effect, the rework rate and the repair cost of hollowing can be effectively reduced.

[0006] The prior art generally uses beating to beat and brush, such as using a steel wire mesh with a size of 12.7mm*12.7mm*0.9mm, repeatedly folding three times (to ensure that the steel wire mesh openings are aligned layer by layer), forming a steel wire mesh plate with an outer dimension of 200*200mm, connecting the steel wire mesh plate with a bamboo piece, and the bamboo piece is used as a handle to form a beating tool.

[0007] However, the existing technology of beating the mortar adopts a fine steel wire mesh repeatedly folded into three layers, the contact area with the cement mortar is insufficient, the hanging mortar rate is relatively low, and the contact area with the wall surface is not large enough, compared with the sprayed cement mortar, although the height and coverage of the burr are improved, but the overall burr base is not strong enough, the burr height does not reach 3-5mm, and because the beater is a handle type, it is easy to cause uneven force on the front and rear ends of the beater surface, and the force between the beaters is inconsistent, resulting in inconsistent thickness, which cannot effectively meet the construction needs. Practical new type content

[0008] The utility model provides a wall plastering base beat mortar tool, which aims to overcome the above-mentioned deficiencies of the prior art, improve the contact area with the mortar, thereby improve the hanging mortar rate, and improve the contact area with the wall surface, meet the burr base and height requirements, and improve the beating mortar effect.

The elastic potential energy of the spring is used for beating the mortar, at equal distances from the wall surface, without considering the spring elastic attenuation, the potential energy is consistent, and the beating mortar demand can be met. The square tube and the round tube are connected by threads, the length can be adjusted, the space where the height is limited and the scaffold cannot be built is suitable, and the working efficiency is effectively improved. The elastic potential strength of the elastic metal wire can be adjusted according to the operation space, so that the quality of the burr is ensured.

[0010] Preferably, the beat surface is a rectangular stainless steel sheet, and a plurality of through holes are uniformly and spaced apart on the beat surface. Compared with the existing technology of iron wire mesh surface, the contact surface with the mortar and the wall surface is larger, the hanging mortar rate is higher, and it is easier to form a burr with excellent quality.

DETAILED DESCRIPTION

[0016] The utility model will be further described in detail in combination with examples and specific embodiments.

[0018] According to the above structure, the rotating shaft 11 is a connecting device for rotating the brush surface 1, and the angle of the brush surface 1 is adjusted by adjusting the elastic metal wire 7 and the non-extendable metal wire 10.

[0019] The elastic potential energy converted by spring 6 is used for mortar application. At equal distances from the wall, without considering spring elasticity decay, the potential energy is consistent. Furthermore, because the mortar application surface 1 has a grid-like, equidistant mesh, the contact area with the mortar is large, resulting in a high mortar adhesion rate. The large contact area with the wall also creates a larger burr base, making it easier to achieve the required 3-5mm burr height. The rod uses a threaded connection, allowing for length adjustment according to the construction height. Specifically...

[0020] The patting surface 1 uses thin stainless steel with uniform holes, which, compared to the existing wire mesh surface, provides a larger contact area with the mortar and wall, resulting in a higher mortar adhesion rate and making it easier to form high-quality burrs.

[0021] The handle and the handle 1 are driven by spring 6. By controlling the distance from the wall according to the mortar conditions on site, burrs can be formed better in narrow spaces, and it is also easier to achieve the required 3-5mm.

[0022] The external thread at the top of the round tube 5 can be formed by threading a lightweight steel pipe.

[0023] A non-stretchable metal wire 10 passes through the middle of the spring 6. By pulling the non-stretchable metal wire 10, elastic potential energy can be accumulated and the angle of the paddle can be adjusted, thus enabling operation in confined spaces and other places where it is difficult to paddle.

[0024] The square tube 4 and the round tube 5 are connected by threads, and the length is adjustable, making it suitable for spaces where scaffolding cannot be erected due to height restrictions, thus effectively improving work efficiency.

[0025] The elastic metal wire 7 can adjust its elastic potential energy intensity according to the operating space to ensure the quality of burr formation.
