1. Building insulation materials have the same life as buildings.
SCS building insulation system is advanced in technology, safe and applicable. The insulation layer is built in the composite shear wall of the building, and the surface is protected by a reinforced concrete protective layer with a thickness of not less than 50 mm, which is not affected by external environmental factors during use, so that the insulation layer does not need maintenance and repair during the whole life cycle of the building, and there is no risk of insulation layer falling off, so that the insulation layer has the same life as the building.
2. Meet the requirements of GB500 16-20 14 Code for Fire Protection Design of Buildings, and solve the problems of selecting A-grade materials for external walls and fire prevention.
Article 6.7.3 of this specification stipulates that when the thickness of protective layer reaches 50mm, thermal insulation materials with fire resistance grade of B 1 B2 can be used. Because the insulation board is sandwiched between the inner and outer concrete layers, it can't touch the open flame. The fire department of the Ministry of Public Security has passed the fire resistance test and the expert demonstration of the construction department, and the overall construction method of the wall can reach the 4-hour fire resistance limit, which solves the problem of the selection and application of A-grade materials for the external wall.
3. When using B 1/B2 thermal insulation material, there is no need to set fire isolation belt.
According to Article 6.7.3 of Code for Fire Protection Design of Buildings (GB500 16-20 14), when the combustion performance of thermal insulation materials is B 1 and B2, the wall of thermal insulation materials should be made of non-combustible materials, and the thickness should not be less than 50 mm .. Except Article 6.7.7. The insulation layer of the built-in cast-in-place concrete composite wall is covered with a concrete protective layer with a thickness of 50-60 mm. When B 1/B2 EPS, XPS and PU(PIR) are used as thermal insulation materials, the requirements specified in GB500 16-20 14 can be met, and there is no need to set fire isolation belt within the specified range.
4. Good seismic performance
The concrete of the protective layer is firmly connected with the main structure through the tie pieces of steel bars to form an integral structure, which improves the lateral force resistance stiffness of the wall and enhances the ability to resist the horizontal force of the earthquake.
5. Rachel is evenly distributed, and the force is clear, so as to avoid concentrated cold and hot bridges.
SCS building insulation system integrates insulation board and protective layer from bottom to top, and the protective layer cuts deformation joints, which solves the problem of temperature deformation compensation caused by long wall. The tie pieces are distributed, and all loads are transferred to the main structure through the tie pieces of steel bars, without changing the normal design steel bars and concrete labels, so as to avoid centralized cold and hot bridges.
6. It provides conditions for the diversification of exterior wall decorative surfaces.
SCS building thermal insulation system solves the security risks such as cracks, hollowing, leakage, falling off, etc. which are easily caused by external wall sticking and external thermal insulation technology at present, and solves the maintenance problem in the later stage of external thermal insulation. The thickness of protective layer concrete reaches 50 mm, which is firmly combined with the main structure, providing conditions for the diversification of exterior wall decorative surfaces.
7. Simple production process, no environmental pollution during construction, and environmental protection.
SCS building insulation system can choose B2, B 1 EPS or XPS insulation materials with high cost performance, which are assembled by insulation materials and steel mesh. The production process is pollution-free and environment-friendly. There is no need to cut and scrap in the construction site, which fully conforms to the development direction and industrial policy of the national green building materials and meets the energy-saving requirements of 75% of the national policy.
8. Rachel uses our patented products, which effectively ensures the displacement of the grid plate during the cast-in-place process.
The insulation board with reinforced grid structure adopts the limit fixing piece on the rebar tie piece, which binds the internal formwork support piece of the main body and the internal and external rebar into a whole to prevent the displacement of the rebar grid plate in the cast-in-place concrete. The connection between the cushion block and the rebar tie piece can effectively ensure that the insulation board does not deviate during the concrete pouring process. Fine stone concrete or ordinary concrete is used for pouring, and screening machine is used for pouring at the same time, which improves the pouring efficiency and quality.
9. Economical and reasonable, with low comprehensive cost.
Concrete can be self-compacting concrete or a certain proportion of ordinary concrete, which reduces the cost of concrete; The internal formwork support on the rebar tie piece is used as the internal support when the external wall formwork is set up, and the connection pad on the rebar grid insulation board is used as the external support when the external wall formwork is set up. The tie piece and the connecting pad replace the formwork top support (or cement pad), so there is no need to place the formwork top support before mold sealing, which reduces the construction process and reduces the cost. Insulation board and related accessories are processed by the factory according to the drawing number, which is convenient and fast to install and low in cost;
10. Simple construction, less labor, fast construction and short construction period.
SCS building insulation system is easy to install. Under normal circumstances, for a building with a building area of 500 square meters, five or six buildings can be constructed simultaneously with the main body, and other types of work (steel workers or carpenters) can also be used instead of construction, which reduces the problem of tight accommodation on site and shortens the construction period.
1 1. Factory customized processing to reduce material loss.
SCS building insulation system is customized by the factory, with simple production equipment and easy assembly process. Each person can assemble 200-300m2 steel grid insulation board in each shift, so the production does not need to invest a lot of money, and the investment cost is saved. Decompose and typeset the drawings in advance, and make the material list of each layer of steel grid insulation board. According to the specific component position of each floor, the component size is determined, and the insulation board and steel grid are cut and numbered according to the component size. Put the finished steel grid insulation products into the site and install them according to the component number position.
12. Increase the floor area ratio by 8%- 10%.
Compared with the traditional masonry structure, the building built with SCS building insulation system increases the building area by about 8% ~ 10%, which makes people get more benefits.
13. Low carbon, energy saving, material saving and good environmental protection performance.
SCS building thermal insulation system meets the requirements of material saving and assembled components in green building evaluation standards, and is a plus item in green building evaluation. It is suitable for saving energy and materials in green buildings, which is beneficial to protecting the ecological environment and belongs to green building materials.
At present, Hebei has issued the Notice on Strengthening the Structural Measures of Composite Insulation Board for Exterior Walls of Housing Construction Projects (Ji Jian Biao [2065438+09] No.2), followed by Baoding City (Cheng Jian Ke [2065438+09] No.208) and Chengde City (Ming Chuan Telecom Shi Cheng Jian Ming Dian [2065438+09] No.4). The document requires enterprises that have obtained the local standard of "Construction of External Wall Composite Insulation Board" issued by Hebei Province before June 2065438+2008 to step up the review and revision of technical standards, focus on the safety of building insulation and structural integration technology, optimize the design scheme of building structure, and promote structural technologies such as large formwork built-in cast-in-place concrete or sandwich insulation cast-in-place concrete with high smoothness and easy control in wall construction.
