Jiangsu new chimney brick chimney Which is good

Jiangsu new chimney concrete chimney Prevention Project 1, material quality control quality light block performance indicators, new chimney wall for generating greatest impact is shrinking, while the relative moisture content is an important indicator of contractility. To this end, the requirements of lightweight block especially lightweight aggregate concrete block must be approved by 28 days before the factory conservation and the use of units must adhere to product acceptance, eliminating the use of substandard products. 2, the better off the structural design of the new lightweight block wall prevent new chimney, we must focus on building design. Designers should be based on the requirements of "small non-load-bearing concrete block masonry engineering point of order", "non-load-bearing concrete masonry structure with small block" and the relevant norms, combined with the use of the functions and features of various building materials, to take effective structural measures before to avoid wall crack leakage. 3, the construction contractor ⑴ control measures should be selected and qualified local manufacturers have Zhunyongzheng. When signing the contract, the construction site to clear blocks of time, manufacturers must ensure age issues, and be held accountable. ⑵ construction unit should strengthen detection block approach. After ⑶ block approach, as soon as possible has been put away construction floor brought into line, decentralized stacking position to masonry and waterproofing measures should be well in advance to ensure that the main structure of water conservation and rain water does not flow into the floor. Try to increase the age for the block, the interval should be laying a week later, and should be measured using electrothermal block moisture. When the moisture content below 15%, square allow construction. ⑷ characteristics for blocks in front of the masonry, should not advance watering wet in order to avoid increasing the water content of the block caused by uneven watering. It should take before the masonry, mortar shop, in the right amount of masonry surface watering practices. ⑸ strengthen Setting ring beams, structural columns, walls over 4 meters long column structure should be set up, more than three meters high wall, ring beam should be located. Long walls and floors and have openings larger, set the column structure should first ensure that both sides of the hole, the hole in order to avoid new chimney corners of contraction. When the body does not stay steel structure, or positional deviation must anchorage. ⑹ Because vulnerable air humidity, as well as the presence of the frame structure deformation difference, should the two sides of the wall tie bar pull-through, improving crack resistance. ⑺ in strict accordance with the rules of construction, to ensure the strength of mortar and mortar joint full (especially vertical joints). After completion of masonry ⑻ to adhere sprinkler maintenance to reduce drying shrinkage of mortar. 1, material quality control quality light block performance indicators, new chimney wall for generating greatest impact is shrinking, while the relative moisture content is an important indicator of contractility.
