Non-setting adhesive mold and method for fabricating facing bricks on site using mold

Abstract

The invention provides a facing brick mold for fabricating facing bricks on the surface of a building on site. The mold is a sheet-shaped hollow mold, wherein a bottom layer laminating film and a surface layer laminating film are respectively arranged on the bottom surface and external surface of the mold, a non-setting adhesive bonding layer is arranged on the bottom layer laminating film, and a layer of anti-sticking paper is further arranged on the non-setting adhesive bonding layer. The invention further provides a method for fabricating wall facing bricks on site by using the mold. The wall facing brick mold and the method for fabricating the wall facing bricks on site by using the mold, provided by the invention, have the advantages that the facing bricks can be fabricated on the building on site, are uniform in color lump and regular in molded face, can be demolded in one time and cannot generate fins.

Description

technical field [0001] The invention relates to the technical field of building material construction, in particular to a self-adhesive mold and a method for using the mold to make facing bricks. Background technique [0002] Existing building wall brick decoration is usually formed by bonding and jointing the wall brick special bonding material with the wall. This traditional tiling process has the following disadvantages: (1) The weight of the wall brick facing layer (about 20kg / m 2 above); (2) construction (pasting, pointing and other processes) work efficiency is low (the work efficiency of conventional skilled workers is 7-8m 2 / day / person); (3) due to the difference in elastic modulus between the wall brick and the bonding material and the controllability difference between the bonding material and the construction, the safety hazard of wall brick falling off and peeling off; (4) due to the sticking The efflorescence of the bonding material (generally cement mortar) ...

AI Technical Summary

Problems solved by technology

This traditional tiling process has the following disadvantages: (1) the weight of the wall brick facing layer (about 20kg / m 2 above); (2) construction (pasting, pointing and other processes) work efficiency is low (the work efficiency of conventional skilled workers is 7-8m 2 / day / person); (3) due to the difference in elastic modulus between the wall brick and the bonding material and the controllability difference between the bonding material and the construction, the safety hazard of wall brick falling off and peeling off; (4) due to the sticking The efflorescence of the bonding material (generally cement mortar) affects the aesthetics of the decorative surface of the wall brick; (5) The decorative layer is prone to water seepage due to jointing materials and construction reasons; (6) The graphics of the wall brick products are not rich enough , the decoration of complex graphics cannot be realized; (7) Consuming a large amount of wall tiles is not good for energy saving, environmental protection, and resource conservation

The disadvantage of these measures is that more special requirements are put forward for the performance of wall tiles, bonding materials, and pointing materials, and the difficulty of control in the construction process and the self-weight of the overall decorative layer cannot be reduced to a greater extent , there are also long-term safety and quality risks of the project

This method has the following problems in the demoulding process. If the primer is wet, the forming surface of the primer will have roughness after demoulding, which will seriously affect the appearance; if the primer is dry, the topcoat will be demoulded in a dry state , due to the demoulding shear and friction effects, the molding surface will split and flash; if the primer is in a dry state and the topcoat is in a wet state, the topcoat has not yet formed structural strength at this time, and the burrs embedded in the primer The mold comes out, and the friction between the top coat and the mold makes the bottom coat produce friction flash and the top coat comes off, which affects the forming surface

At the same time, since the surface coating is made of aggregate coating, its construction can only be plastered or sprayed, and the differences in stubble and finish texture between the two construction surfaces will cause color difference

Therefore, it is difficult to obtain a decorative effect with uniform color and regular graphics by this method.
