The basic points of the granite dry hanging construction method

This benevolent brother put the construction disclosure on the bottom, and he finished his business.

Kiss! Hello, happy to answer your <>

The technical points of the pro-stone dry hanging method are as follows: 1. The technical requirements and properties of the steel used in the metal skeleton should conform to the current national standards. Its specifications and models should meet the requirements of the design drawings, and hot-dip galvanized products should be used if section steel is used outdoors.

The variety, size, shape, pattern, shape and color of the slate should meet the design requirements. The thickness of the slate must not be less than 25 mm. 4. Other materials:

Stainless steel gaskets, foam rods, expansion bolts, pendants, spring gaskets, etc. Hope mine can help you <>

The construction method of dry hanging on the exterior wall is very, very commonly used, through the way of dry hanging, various undesirable phenomena can be effectively avoided in ceramic tiles and stones, such as cracks, hollow drums, etc., which significantly improves the durability of exterior wall decoration and, at the same time shortens the construction period to a certain extent, and the dry hanging can be accepted as long as it is done, and there is no need to wait for material hardening or other factors. Next, I will introduce to my friends the construction method of dry-hanging granite walls.

The first step of dry-hanging granite wall is the treatment of the base layer, use a broom to clean the surface of the base surface of the wall next to the key, clean the convex part that affects the installation of the skeleton, check the wall according to the position of the drawing design, and whether there is local chiseling to ensure the decorative effect.

Before the construction of the dry-hung granite wall, the horizontal control line and vertical line should be played on each layer according to the elevation data of the design drawings.

Dry-hung granite walls are fixed with 12 mm expansion bolts, and the fixed spacing of expansion is the same as that of granite; If it is a lightweight wall, then it should be fixed to the ground at the time of installation, fixed with a spacing of no more than 600 mm.

The angle between the angle steel and the stone of the dry-hung granite wall is the same, and the part is directly connected to the wall. When installing the skeleton, pay attention to its verticality and flatness.

The installation of dry-hung granite wall adjustment parts is determined according to the size of the stone, the adjustment parts are made of stainless steel, and the adjustment pieces should be properly processed according to the design drawings, and the adjustment parts should be connected with the skeleton with screws, and the adjustment pieces must be installed firmly.

When installing stone on a granite wall, start from the bottom floor and install it vertically upwards. Pay attention to the installation should be handled gently, according to the accurate position adjusted in the drawing, immediately clean the hole, inject bone glue into the hole, pay attention to the coagulation of bone glue takes 4-8 hours, in order to avoid premature coagulation and brittle fracture, coagulation too slow and loose.

After completing the dry-hanging granite wall joining or bonding, clean the stone surface with cotton yarn, etc. After the glue solidifies, clean the surface of the stone with a wallpaper knife, cotton yarn, etc.

The construction steps of the granite wall surface of the bright chain dry hanging of the exterior wall are basically the same as the steps of the dry hanging of marble and the dry hanging of ceramic tiles. But the difference is that the surface texture and color of granite itself are relatively special, not only with many types, but also with high requirements in terms of color. Color is also the main consideration for granite laying, to avoid visual color difference, which requires more effort during installation.

The new national standard "Interior Decoration" atlas stone wall design and construction points are explained.

In order to improve the design level of China's decoration projects and unify the construction standards and methods, Tang Zenglie, an expert in the expert database of China Building Decoration Association, invited the China Architectural Design and Research Institute Environmental Art Design and Research Institute to organize several domestic interior design companies to compile and publish the "Interior Decoration" (03J502-1 3) after nearly two years. This set of new national standard atlas has a total of 3 books, including three categories of interior decoration practices: interior wall decoration, ceiling and floor. It preliminarily solves the problem that China's decoration design is not based on the national standard atlas.

Interior wall stone wall practices are only a small part of the 03J502-1 atlas. However, the stone interior wall in the interior decoration project, especially in the public building interior decoration project, occupies a large proportion of the cost, is a very important sub-project in a unit project. At present, there is no complete set of relevant design specifications in China, in the actual engineering, many projects are lacking the calculation book of steel skeleton production and dry pendant, and the construction practices and construction requirements are not clear, and some customary practices have unsafe hidden dangers.

Combined with the actual construction in China, summarize the construction practice experience in recent years, and compile a set of safe, reliable, universal and feasible, with a certain scientific basis for the interior wall stone wall practice, is a general requirement in the industry. In the 03J502-1 atlas, three common practices are included in the stone dry hanging, stone dry sticking and stone wet pasting. At present, a small number of projects have adopted the back bolt type dry hanging method, although the back bolt material and the node strength test have been measured and approved by the national inspection agency, but its installation accuracy is more suitable for the practice of wall joints, and the details such as wall socket openings need to be further solved.

The design and calculation of the back-bolt dry hanging method requires higher professional knowledge, and the back-bolt dry hanging method is not included in this time. Wet patches are not recommended and are limited to certain areas for use in wet rooms such as restrooms. In the case of conditions, it is also advisable to use special adhesives for stone.

The practice of dry hanging on stone walls has been popular in China for many years, but there has been no relevant design specifications and special acceptance specifications, and there are no special technical standards. In the preparation of the national standard atlas, the main reference is the current relevant design codes, of which the "metal and stone curtain wall engineering technical code" (JGJ133-2001) is for the outdoor curtain wall preparation, although the general height of the inner wall is not high, basically do not consider the role of wind load, but the relative installation accuracy requirements are more stringent, in some structural requirements are slightly stricter. If it is stipulated that the area of each stone should not be greater than, it is in the external curtain wall.

Here are a few key points of the new atlas.
