Construction method for using drain board as hollow painting or embedding foam strip into floor

Abstract

The invention discloses a construction method for using a drain board as hollow painting or embedding foam strips into a terrace, and belongs to the technical field of building waterproofing, moisture insulation, heat preservation and indoor moist wall surfaces. A plastic drainage plate does not absorb water, so that a painting layer is easy to generate shrinkage cracks. According to existing floor concrete, partition seams are cut on the surface, but the partition seams cannot be cut from the surface during wall painting, and according to the method, firstly, foam strips are pre-buried, then painting is conducted, so that natural partition seams are formed in a painted base layer, and after the base layer is dried, surface layer coating is conducted, or mesh cloth is pasted firstly. On a non-water-absorbing plastic plate, the painting is divided into a combination relation that the inside contains the bin dividing seam and the surface is integrated. The hollow painting solves the problem of shrinkage cracks, is also suitable for concrete hollow terraces, and is an innovative invention method.

Description

Technical Field

[0001] The invention discloses a construction method for using a drainage board as a hollow plaster or embedding foam strips in the floor, which belongs to the technical field of building waterproofing, moisture insulation and heat preservation, especially relates to underground engineering and indoor humidity. Background Art

[0002] The inventors have been continuously researching, developing, and improving hollow stucco on drain boards. Because plastic drain boards don't absorb water, shrinkage cracks easily form in the stucco layer. Existing concrete floors have compartmentalized seams cut into the surface, but wall stucco can't be made from the surface. This led to the invention's method, which involves pre-embedding foam strips before stucco, creating natural compartmentalized seams in the stucco base. After the base dries, a topcoat is applied, or mesh is applied first. The present invention's solution, on a non-absorbent plastic board, divides the stucco into compartmentalized seams on the inside, while maintaining a single, integrated surface, eliminating stucco cracks. This method is also applicable to hollow floors. Summary of the Invention

[0003] After placing the drain board on the wall, secure foam strips to the board's surface, spacing them 0.5 to 6 meters apart. These can be vertical, grid-like, or in other configurations. Then, use expansion tubes and mesh to secure the board to the structural wall, and apply mortar. The drain board can be a flat plate with a fulcrum, or it can be constructed with grooves in the plate to more easily secure the foam strips within the grooves. The base mortar is divided into compartments by the foam strips. After shrinkage, fiber mesh is applied to the mortar, and putty, surface coating, or other decorative finishes are applied. This can also be used on hollow concrete floors, where the decorative surface is integral, with the shrinkage joints located in the middle of the concrete surface layer. The drain board is placed on the ground, unlike on the wall, in that it no longer requires expansion tubes for securement, and the mortar is applied as a single-pour concrete surface.

[0004] The beneficial effect of this invention is that, on a non-absorbent plastic drain board, foam strips are first used to create shrinkage cracks in the plaster base layer. The internal cracks are contained within the plaster base layer, while the surface is a single, integrated structure. This hollow plastering method solves the problem of shrinkage cracks and can also be used on hollow concrete floors. This is an innovative invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 5 This is a schematic diagram of wall painting. 4 is the structural wall, 2 is the fulcrum of the drainage board, 3 is the foam strip, and then the mesh (including wire mesh) 7 is placed. It is fixed to the structural wall 4 with an expansion tube 10. Then the bottom layer of paint 6 is applied. The paint layer 6 is divided into compartment seams by the foam strip 3. When the paint 6 is stable, the mesh 8 is applied, and the surface putty and paint 9, or other decorative surfaces, are applied. (When used for flooring, there is no fixing part of the expansion tube 10, and the structural wall 4 is the base plate).
