Press-bonding hanging type decorative board and its producing method

Abstract

The sticky pendent ornament veneer comprises a surface plate, with sheet mesh cement sticking to the back of the surface plate. It also relates to the built in pendent ornament inside the cement and combining with the outer wall. It starts by cutting the surface plate into specified plates, burying the bottom of the pendent ornament using glues at the back of the surface layer forming a cement material base, spreading sheet mesh and coating it with cement and solidifying and drying the coating with the surface plate. It is safe, fine in performance, simple, easy in process, low in cost, material saving, and particularly suitable for big thin plates, especially new constructing plates.

Description

(1) Technical field [0001] The invention belongs to the field of preparation of new building materials, and in particular relates to a method for making a pressure-bonded hanger type decorative panel. (2) Background technology [0002] The use of stone veneer as the indoor and outdoor decoration of buildings has the characteristics of high-grade quality, natural effect and good durability, and has been widely used. [0003] The stone veneer panels used in the early building exterior walls were connected to the exterior wall by wet hanging method. Due to many problems, at present, dry hanging stone technology is mostly used, such as pin connection, sheet connection or back bolt connection. Among them, the pin connection is shown in Figure 1. The construction method is to open a pin hole 12 of a certain depth on the end surface of the stone veneer 11, insert a pin 13 into it and fix the pin in the hole with structural glue, and the pin is partially exposed. In the hole of a c...

AI Technical Summary

Problems solved by technology

[0004] These installation techniques have obvious disadvantages, such as the wet hanging method, because the stone decorative board is in direct contact with the cement wall, it is prone to white blooms, pan-alkali and flooding, which seriously affects the decorative effect of stone materials; The dry hanging process is to punch holes and slots in the middle of the stone section. In order to ensure the horizontal force of the stone, the thickness of the stone is required to be thicker, generally 25-35 mm thick

Due to the large thickness and heavy weight of the stone, it is unfavorable to the safety of the main structure of the building, especially for high-rise buildings. The problem of thick stone is that the stone decorative board used is relatively thin, but because the frontal wind pressure is only concentrated on a few points, when the wind pressure is high and the stone is thin, it is easy to form penetration and fracture, which has hidden quality problems

Moreover, the above processes are all on-site operations, limited by equipment, personnel, and materials, and the quality is very unstable. These problems have been plagued by designers and users, and have affected the wide use of stone decorative panels.

Although this kind of stone veneer has many advantages such as good safety, excellent performance, and convenient and quick installation, because a certain depth of installation groove must be opened on the back of the stone, the stone itself must meet the thickness requirement of at least 10-15mm. Grooving not only requires special tools, but also has certain technical difficulties, which limits its application to a certain extent

Especially at present, the building materials industry continues to introduce new products. For example, stone slabs can be processed into large slabs with a thickness of 3mm and an area of ​​600mm×800mm or larger, and porcelain slabs can also be produced with a thickness of 3mm and an area of ​​1200mm×2400mm or larger. The above-mentioned process cannot be used for these thin and large plates, which makes it difficult to popularize and use these new plates
