Introduction to "concrete model block"
Land is a scarce natural resource that human beings depend on to survive.
Currently, China's per capita arable land is less than 1.7 acres, below the UN's warning line. The state council in 1999 for coastal cities and other urban land resources are scarce, banning the use of solid clay brick, and according to the possible conditions limit the production and use of other clay products. The Shanghai building design institute limited company has been strongly supported by the city construction committee leader to develop the new type of wall material, concrete model block. The research and development of concrete mold card block, before and after five years, has obtained the national Patent Office issued two patents and access to the Shanghai municipal people's government issued by the Shanghai science and technology progress third prize. Through more than a dozen pilot project 110000 square meters of construction engineering research and application of the in material, design, construction technology, quality acceptance each has made significant achievements, such as accumulated rich experience. The pilot building of "huili garden" in pudong has been awarded the third prize in the design of the Chinese architectural society. Codes for design of mould card concrete building blocks, the modulus of concrete block construction and quality acceptance regulation approved by the Shanghai construction and management committee of Shanghai municipal engineering construction standards, and on December 1, 2004 in the city. The concrete module card block external thermal insulation system of energy conservation building structure map ", the concrete module card block structure figure 2 atlas has Shanghai construction and traffic committee approved on March 1, 2006 in the city. The concrete model block is a new type of wall material with a new concept of special appearance. Up and down or so have tenons, die card block masonry without mortar, and rely on male female tenon with build by laying bricks or stones, block and block between the up and down or so firmly stuck, interlock. At the same time in all vertical slot into the rate of hole and prior graded according to the requirement, and is composed of cement, fine aggregate, coal cinder, stone chips), mineral admixture, fly ash, slag powder), additive and water pouring hole size, etc. Its special construction, the product has the strength high, the technical performance index is good, the force is reasonable, the characteristic of the weight is light, is very good the bearing masonry material. It is in accordance with the national industrial development policy to utilize industrial waste without burning. The biggest difference between the concrete block and the block is:
The anti-pressure and shear strength of model block are not only better than small block, but also better than clay brick and clay porous bricks.
The construction is simple, the building is fast, it is good for the construction quality, and the construction progress is accelerated.
Improving the efficiency of work, reducing the overall cost and labor intensity, and improving economic efficiency;
The whole body is good, it is convenient to decorate several times, and the building block is self-preservation material, it is more advantageous to building energy saving, for the benefit of future generations.
The basic physics and mechanical properties are good enough to meet the requirements of the wall materials. We are specialized in building design and research of Shanghai science and technology enterprise, the more fully recognize the importance of building energy efficiency, we actively responded to an appeal by the city government, from the source construction, design, implement various energy-saving measures and technical requirements, create a new situation building energy conservation work.
