Prefabricated modular houses reinforcement design train of thought
1) the reinforcement design of component activities room, construction and commitment, and strive to achieve units, construction units according to the activities of the board level implementation identified experience and a more reasonable design.
2) reinforced concrete structure housing service life, by the owner and the design unit, generally 30 years specified agreed. Reinforcement for several years has been used and not more than 50 years of life structure and the structure of the local, as the owners of the project requirements or special needs, have a longer life expectancy, measures should be taken to strengthen the activities of the board if necessary, experts will convene a meeting, discuss solutions. The original seismic design, seismic fortification criterion of low intensity or old concrete building structure design, most existing code for strengthening housing is difficult to meet the design requirements.
3) activities of the housing reinforcement reinforcement and reconstruction activities of the Board shall be designed by the design unit has the qualifications or scientific research units.
4) identification and detection of modified steel construction drawing design documents, but also need and file map construction new, send the document review the construction plan review department, if the main street in a building facade or large temporary transformation on the original roof, design documents shall be approved by the local planning departments in the design of the activities of the board (including test the report, identification and evaluation of data, design drawings and calculation, the relevant approval documents etc.), engineering and new design. XH5 Zhejiang building network 7.) Reinforcement design used in the transformation should be light, in order to reduce the seismic response, to avoid the original foundation reinforcement; layer should increase the use of steel roof structure, light maintenance structure; atomic structure, reduced or no reinforcement, influence the use to lower housing, reduce the activities of the board power transmission reinforcement part, the original should be clear, simple structure, the existing structure with less or no damage to the activities of the board, convenient construction, low cost solution; need lag caused an increase in material strength pressure considering the force, should be the second part of the new standards, regulations and make the corresponding discount; should follow the construction is simple, convenient, we can guarantee housing quality, which is one reason.
