Reconstruction of old buildingRetrofit elevator, has been a hot topic of public discussion in the past two years, and is also the focus of the transformation of old areas supported by ******。So when installing an elevator in the old building, what identification needs to be done to the building？和Changsha elevator installationCompany up to look at it!
   1, the type of house structure, the number of building floors, the address of the house, the construction age, the orientation of the house, the general situation of the house decoration and the use of the house are investigated on the spot。
   2, the existing superstructure of the building and structural layout, component size, layer height of the field measurement。
   3. Measure the inclination rate of some vertical components of the house to analyze whether the inclination rate of the house exceeds the limit。
   4. Inspect and measure the appearance of the superstructure, envelope structure, building decoration and construction equipment of the house, and inspect the appearance and take photos of the damage of some typical components (deformation, cracking, subsidence, leakage, exposed tendons, etc.)。
   5. The reinforcement detector is used to detect some reinforced concrete columns, beams and slabs of the house and find out the reinforcement information of some reinforced concrete column walls, beams and slabs of the house。
   6. According to the requirements of relevant testing standards, a certain number of reinforced concrete column walls and beam components of the house are extracted and the concrete compressive strength is tested by resilient method。
   7. According to the requirements of relevant testing standards, a certain number of reinforced concrete slab members of the house are extracted and the concrete compressive strength is tested by the core drilling method。
   8. According to the requirements of relevant testing standards, a certain number of load-bearing brick wall components of the house are extracted and the compressive strength of masonry mortar is tested by penetration method。
   9. According to the requirements of relevant testing standards, a certain number of load-bearing brick wall components of the house are extracted and the compressive strength of brick blocks is tested by resilient method。
   10. The bearing capacity of the load-bearing members of the superstructure of the building shall be checked and calculated according to the on-site inspection and test results and the transformation plan provided by the client, and in accordance with the relevant specifications ******。
   11, according to the inspection, testing and verification results, determine whether the current situation of the house meets the requirements of the carrying capacity after the renovation (with the installation of elevators)。
   12. Inspect the original seismic structural measures of the house, analyze the role of the structure to be demolished in the house structure according to the proposed reconstruction plan, and evaluate whether the reconstruction plan affects the original seismic performance of the house。

  Above isChangsha elevator installationThe company compiled about the old building renovation and installation of elevators need to do identification, for reference, Hunan Alpha elevator is a professional elevator installation, elevator maintenance, elevator installation company, welcome the need of new and old customers to come to consult。
