Stone decoration quality control

Stone plaque in the natural, luxurious, beautiful wait for a characteristic in decoration industry has become more and more widely, and will continue to from indoor to outdoor, from low to high altitude, from small to large development. A few years ago, only stone curtain wall in the building now dado, but to tens of meters, hundreds of meters tall development. Imagine, high-level decorative glass than to 5 times heavier hundreds of thousands of stone, if because of raw materials, technology, construction methods exist, resulting in blocks fall from the sky, the consequences would be disastrous. Therefore, the quality of stone decoration not only affects the decoration effect, the quality of the project, but also related to the safety of people's life and property.

Stone decoration quality is a complex system engineering, which includes the design quality, construction quality, stone quality, process quality, etc..
Process quality control

In recent years, the stone veneer dry hanging process has been rapid promotion. Mainly with steel pin connection, back bolt method, short slot connection, slot connection method, the composite connection method, the method is in the main structure design main points; the metal Guajian stone will be fixed in the buildings, forming decorative stone curtain wall. Its main advantages: one is improve the safety and durability and can effectively avoid the wet paste process plate hollowing, cracking, peeling and other phenomena: second is to keep the wall clean and beautiful, to avoid the phenomenon of whitening, discoloration; three is to improve the construction conditions, reduce the labor intensity, speed up the progress of the project. Stone curtain wall dry hanging method, has obvious advantages, but the cost is high. How to ensure the quality, safety, reduce costs, improve the construction technology, improve economic efficiency, is the first stone to solve the problem.

Material quality control

Stone material decoration materials is the key to ensure the quality of the project, in addition to the stone, the main steel (aluminum) skeleton material, hanging plate, hook, structural adhesive and sealing, etc.. The selected aluminum, steel and other materials, must comply with the national standard requirements. The plating layer on the surface of aluminum material must meet the requirements of the national AAl5 level, the steel must be hot dip galvanized or other anti-corrosion materials for processing, in order to ensure that it does not occur. The connecting plate shall be used for 3mm above the stainless steel plate or 4mm above the aluminum plate. Structural adhesive and resistant to the adhesive must be in line with national standards, to ensure that no oil leakage.
Large engineering, decoration companies to provide complete and complete stone factory, complete stone decoration, for processing time reference. If possible, the best sent to the stone processing site inspection.

Construction quality control

Stone decoration engineering construction process, the project is very complex, which requires all aspects of strict control, close cooperation. Stone curtain wall works are generally in the main structure of the main structure, within a period of time within the decoration work, a short period of time, related to the progress of the whole project, which requires the decoration company in advance to prepare for the work, including various materials, including the performance of the supporting materials, must be carried out in advance. Exterior wall stone decoration construction are open operation, by the impact of climate, welding and other types of work can not be in the rain, can not operate in the hot sun, to find ways to reduce the constraints of climate conditions. A wide range of stone curtain wall, welding, electric drills, cutting machine is widely used, power consumption and concentrated, which need to construction units to solve the problem of electricity. At the same time, but also to solve the construction scaffolding, stone semi-finished products, finished products and other work.
In the construction, construction and technical personnel must adhere to the certificates, key technical positions, should first try. In the design should be further improved, against the wind, seismic, material selection, connection structure design and so on to carry out strict censorship. Implementation of the process of the quality acceptance system, including decorative stone production, skeleton installation, hanging plate, hook installation, stone installation and other processes, design and implementation of strict inspection and acceptance, to check the process to carry out the rectification and rework, until qualified, then the next process. The skeleton installation stone curtain wall embedded parts position during the key control structure of civil construction, the quality of embedded parts. Outside wall stone installation key check stone and hanging plate, hook fixed connection of quality. Engineering supervision to every link, in particular, hidden links, to carefully check, supervise the record, to ensure the construction quality. The large area stone curtain wall all must carry on the function test, including the wind pressure test, the water tightness test, the air permeability test, the seismic test, in order to ensure the safety.
