Description

Technical Field

[0001] The utility model relates to a leveling frame with a reserved groove for a skirting line embedded in a wall plastering, and belongs to the technical field of auxiliary equipment for building construction. Background Art

[0002] During the construction of a fully furnished house, uneven surfaces may occur in later masonry walls, which require plaster leveling. For walls with built-in skirting, to avoid secondary grooving later, the bottom of the plaster leveling layer must be positioned to prevent the plaster leveling layer from being applied to the built-in skirting.

[0003] Existing technology for limiting the positioning of the bottom of a gypsum screed is disclosed in Chinese Patent Publication No. CN103899075B. Although a Z-shaped construction ruler can be used to limit the positioning of the bottom of the gypsum screed, the bottom of the construction ruler contacts the floor or the ground, and the top of the construction ruler contacts the bottom of the gypsum screed. Pulling the construction ruler outward horizontally will damage the bottom of the gypsum screed. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a leveling frame with a reserved groove for embedded skirting in wall plastering.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a wall plastering embedded skirting line reserved groove leveling frame, comprising:

[0007] A positioning plate that can be lowered vertically from the bottom of the gypsum leveling layer.

[0008] The positioning plate is provided with a boring, in which a rotatable lifting bolt is installed. The lifting bolt can be raised and lowered and screwed onto the supporting arm.

[0009] The support arm is connected with embedded screws which are embedded and fixed in the wall.

[0010] It also includes a wall with embedded screws, and the support arm is fixed to the wall through the embedded screws; a gypsum leveling layer is provided on the wall, and the positioning plate contacts and positions the bottom of the gypsum leveling layer.

[0011] The suspended end of the support arm is screwed with a support screw, and the support screw supports the suspended end of the support arm in a lifting and adjusting manner.

[0012] The middle part of the support arm is provided with a threaded through hole which can be raised and lowered and is screwed with a lifting bolt, and the top of the lifting bolt is located in the hole and can rotate without passing through.

[0013] A slurry leakage hole is provided on the positioning plate away from the gypsum leveling layer; the slurry leakage hole is conical.

[0014] The beneficial effects of the present invention are as follows: both ends of the positioning plate are lifted and supported to the corresponding height by lifting bolts, and the gypsum leveling layer is applied to the wall surface by scraping. The positioning plate positions and limits the gypsum leveling layer to form a reserved groove for the embedded skirting line. After the scraping is completed, the lifting bolts rotate and descend on the support arm. At this time, there is no obstruction below the vertical position plate and there is space for it to fall, which solves the problem that the top of the construction ruler hits the bottom of the gypsum leveling layer, and the bottom of the gypsum leveling layer will be damaged when the construction ruler is pulled out horizontally.

[0018] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0019] like Figures 1 to 2 shown.

[0020] The present application discloses a leveling frame for a wall plastering with an embedded skirting line reserved groove, comprising:

[0021] The support arm 1 is fixed to the wall 2 by embedded screws 11. The free end of the support arm 1 is screwed with a support screw 12. The bottom of the support screw 12 is used to support the ground or floor. The support screw 12 supports the free end of the support arm 1.

[0022] A threaded through hole is provided in the middle of the support arm 1, and a lifting bolt 31 is screwed in. A positioning plate 3 is supported on the top of the lifting bolt 31. A blind hole is provided on the positioning plate 3 for the lifting bolt 31 to rotate without passing through. When the lifting bolt 31 rotates and rises on the support arm 1, it can support the positioning plate 3. When the lifting bolt 31 rotates and descends on the support arm 1, the positioning plate 3 falls vertically downward by its own weight.

[0023] A mortar leakage hole 41 is provided on the positioning plate 3 away from the gypsum leveling layer 4. The mortar leakage hole 41 is conical. After the mortar applied to the gypsum leveling layer 4 falls onto the positioning plate 3 close to the gypsum leveling layer 4, the accumulated mortar can be scraped out from the mortar leakage hole 41 and collected for reuse.

[0024] Before the wall 2 is scraped and coated with the gypsum leveling layer 4, the two ends of the positioning plate 3 are lifted and supported to the corresponding height by the lifting bolts 31, and then the gypsum leveling layer 4 is scraped and applied to the wall 2. The fallen mortar accumulates on the positioning plate 3 and is scraped from the leakage hole 41 and collected for reuse. The positioning plate 3 positions and restricts the gypsum leveling layer 4 to form a reserved groove for the embedded skirting board. After the scraping is completed, the lifting bolt 31 rotates and descends on the support arm 1. At this time, there is no obstruction on the vertical downward direction of the positioning plate 3 and there is space for falling. The positioning plate 3 falls vertically downward by its own weight, which avoids the situation where the positioning plate 3 easily damages the bottom of the gypsum leveling layer 4, and solves the problem that the top of the construction ruler is against the bottom of the gypsum leveling, and the bottom of the gypsum leveling layer will be damaged when the construction ruler is pulled out horizontally.
