[hot review]
With the development of the construction technology and materials industry, a growing number of non-linear, fluid-sensitive designs have been able to move away from paper and take shape. The use of these three materials is indispensable。
While the three materials are widely used, there is a lack of knowledge of the materials in question, which does not allow designers to understand them and which limits their use。
In the course of this session, we brought to you a presentation of the grc materials, which focused on the following issues:
What's the difference between grc and grg
In which areas is the gcf applied
Three. Why use grc
Four, grc is so good. How should we use it
Grg, grc, grp
The material used in the picture is our main actor today, the grc。
Don't worry. All three materials are composited with glass fibre
Grg (glassfiber reinforced gypsum) is a fibreglass enhanced plaster prefabricated. G means plaster。
Grc (glassfiber reinforced cement) refers to fibreglass reinforced concrete prefabricated units. C means cement。
Grp, another name is frp (fiber reinforced plastics), commonly known as glass steel. P means plastic。
And then we officially started sharing grc knowledge points。
Grc, fully known as glass fiber reinforced concrete, is called fibreglass enhanced concrete in chinese。
It is enhanced by fibres resistant to alkaline fibres, with sulphate low-alkaline cement as glued and integrated into suitable aggregates to form the base of light, high and resilient, multifunctional new inorganic composites made through processes such as jetting, emulation, crowding out and fluid slurries。
The same performance and lifetime as concrete is a green building material for renewable recycling。
Areas of application of the grc
Case of outside construction
The grc is used mainly in the area of construction, for exterior decorating of buildings and for exo-wall decorating of indoor spaces, and also for architectural decorative components and landscapes。
Cases of use of indoor and outdoor walls
The most frequent use is of the building skin. In modern buildings, all types of building formation, all types of outer-surface design are well equipped to meet design requirements and achieve design effectiveness。
Architectural components
The use of the grc in indoor space is mostly in large, open public space, giving space a sense of future and science fiction。
Artscape
Architectural components are the most used places in the grc, and market products of various grc components, such as the roman pillar of the grc, the grc fence, the grc horn line, the grc window set, the grc vase bar, etc。
Why use grc
There must be a reason why, as the saying goes, without unprovoked love, the grc can be universally recognized and widely applied。
1. Current pains in construction
1) a gap between conceptual design and physical location
The famous female architect, zahhadid, was once called “paper architect”. It is because conceptual design has remained on paper and cannot be translated into reality without technical support。
In recent years, an increasing number of architects have designed non-linear buildings in complex and variable forms. Higher demands are placed on building technologies, which need to be built as a bridge for conceptual design and physical landing。
2) reduction in the number of construction workers。
Construction workers are also facing shortages as china accelerates its integration into an ageing society, reducing the number of young adults of appropriate age。
3) construction quality is difficult to control。
The quality of the work was constrained by a number of factors and the quality of the work was not controlled。
4) high energy consumption in buildings, causing serious energy waste。
The state has been advocating for energy-saving reductions and demands for lower energy consumption and green, energy-efficient buildings。
2. How can the grc be favoured by the market
1) plasticity
The grc product is a blending of raw materials, which is sprayed in the moulds and produces products that are rich in form and of diverse quality. The designer's design dream can be perfected by any artistic configuration that is tailored to the different needs of the client and the designer。
2) low quality and high intensity
The volume density of the grc is about 1. 8-1. 9, 8 mm standard grc plate weight is only 15 kg, with resistance exceeding 40 mpa and resistance exceeding 34 mpa, significantly exceeding international standard requirements。
3) polytechnic, large size
The minimum size of the grc sheet is 5 mm, with a standard width of 900 mm and 1,200 mm and an unlimited length, sufficient to meet the conditions of transport, or between 5 mm and any thickness, of any size。
(4) colorful and diverse
Grc products use homogenous penetrating mineral raw materials, which can be produced in different colours and shapes according to the needs of the customer。
5) good taste, good sense
The surface of the grc product can be used to produce different qualitative and sensory effects, such as sand-spray, twig, light-face, etc。
6. Environmental, non-radiation
The grc is a renewable material that is environmentally friendly. The raw materials do not contain radioactive nuclear elements and are environmental materials of national radionuclide level a。
In response to the pains faced in the construction sector, we found that the reason for the widespread application of the grc was to address the pains and match market needs。
3. The advantages of grc application in actual projects
Shanghai treasure centre
1) the plant produces a grc modular curtain wall of varying sizes for transport to the construction site for installation. This form of intensive assembly has been strongly promoted by the state in recent years. The quality of construction can be ensured without involving too many construction workers。
2) designed in the form of dents, which control the lighting of indoor space and also provide for the protection of the sun. Create more comfortable indoor environments while reducing energy consumption of air-conditioning and achieving building-efficient requirements。
3) reliance on the plasticity of grc materials, with more extensive language expression in architectural design and application to more diverse architectural forms。
4) the overall fit, which is installed at a fast pace, has a short construction life on the site and has obvious economic and social benefits。
Grc is so good. How should we use it
The designer designs the drawings in depth and separates them according to production requirements before they are handed over to the ministry of production. Production by the ministry of production is based on model selection materials。
Production process:
Maintenance of the production of moulds and simulators
Construction process:
The measuring, wiring and wiring of the grc plate layouts and the processing of steel skeletons are accompanied by the installation of the grg, grc, grp plate coating surface treatment。
Process flowchart for production
Installation process:
The curtain wall materials are mounted in a dry-mounted manner. The curtain wall materials and skeletons are connected to the building by swelling bolts, and the length of the curtain wall is controlled by the dry wall hanger。
This paper focuses on the use of the grc material in buildings, indoors, landscape areas; the use of the grc material to solve current problems in the construction area; and the installation of the grc material using dry-mounted means。
