Description

Technical Field

[0001] This utility model relates to the field of decoration engineering technology, and particularly to the field of wall plastering technology, specifically referring to a plastering device for inside and outside corners. Background Technology

[0002] Decoration and renovation projects, also known as interior decoration projects, refer to a complete set of construction and design plans carried out in a certain area and scope, including water and electricity construction, walls, floors, ceilings, landscaping, etc., based on certain design concepts and aesthetic rules.

[0003] The purpose of renovation projects is to protect various building components from the erosion of natural wind, rain, and moisture, improve heat insulation, sound insulation, and moisture-proofing functions, enhance the durability of buildings, and extend their service life. At the same time, it creates a better production, living, and working environment for people.

[0004] In building decoration, inside and outside corners are a special type of wall corner. As the name suggests, inside and outside corners are the concave and convex corners of a wall. The concave part is the inside corner, such as the angle between the top surface and the surrounding area; the convex part is the outside corner, such as the angle between the window opening and the wall. Plastering these corners is often quite tedious, and traditional manual plastering is inefficient and difficult to guarantee quality. Currently, when plastering inside and outside corners of walls, it is usually done manually using a trowel and scraper to apply the plaster to the wall surface. The thickness of the plaster needs to be leveled manually, and the accuracy of observing the thickness with the naked eye is not high enough, which can easily lead to unevenness.

[0005] Therefore, it is desirable to provide a plastering device for inside and outside corners, which can plaster inside and outside corners efficiently and accurately, and speed up the construction process. Utility Model Content

[0044] In use, taking a vertically oriented wall arranged in the left-right direction as an example, with a window opening in the wall, it is necessary to plaster the horizontal external corner between the top wall of the window opening and the front side of the wall. Place the support frame 1 of this utility model on the ground in front of the wall, apply plastering material to the upper side of the horizontal plastering board 8 and the rear side of the vertical plastering board 9 of the plastering tool 7, and then adjust the position of the adjusting rod 6 relative to the fixed bracket 5 along the length direction of the adjusting rod 6 to adjust the height of the plastering tool 7.

Then fix the ground fixing piece 2 on the ground, and move the guide slider 4 left and right on the guide slide rail 3. Through the fixed bracket 5 and the adjusting rod 6, the plastering tool 7 moves left and right to plaster the horizontal external corner.

[0045] With the lower side of the horizontal plastering board 8 adjustable in the left-right rotation angle relative to the rear end of the adjusting rod 6, by rotating the lower side of the horizontal plastering board 8 90 degrees downward and backward in the left-right direction relative to the rear end of the adjusting rod 6, the horizontal plastering board 8 becomes vertical and the vertical plastering board 9 becomes horizontal. This can be used to plaster the horizontal external corner of the bottom wall of the window opening and the front side of the wall, thereby expanding the scope of application of this utility model and improving the flexibility of its use.

[0047] In summary, the corner plastering device of this utility model can plaster corners efficiently and accurately, accelerates construction progress, has a clever design, simple structure, is easy to manufacture, and has low manufacturing cost, making it suitable for large-scale promotion and application.

[0048] Therefore, it is evident that the objective of this utility model has been fully and effectively achieved. The function and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the stated principles, any modifications can be made to the implementation methods. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
