Problems solved by technology

At present, for the existing houses with the following simple structure: that is, including the masonry foundation, the outer wall and the roof, if the house is lifted high enough, it is hoped to improve the use capacity and scope through transformation, and expand the area and use space. Most of the effective and practical transformation methods choose to demolish and rebuild, because adding indoor columns will result in too many indoor columns, which is inconvenient to use and does not improve the structural safety. The floor structure is independent and belongs to the platform structure. During the earthquake, it is easy to produce vibration superposition damage, which brings a lot of inconvenience to the house renovation

Embodiment 1

[0072] Include the following steps:

[0073] ⑴Based on the actual load after the renovation, calculate the dimensions and positions of the foundation, columns and beams according to the conventional frame building structure. roof 4;

[0074] ⑵Mural pillars and additional layers

[0075] According to the calculation results, arrange the location and implement structural modification; specifically include:

[0076] ①Basic treatment

[0077] The newly added reinforced concrete foundation 9 and the newly added rubble concrete foundation 10 are required to be processed one by one separately, and the next one must be completed after the previous foundation treatment is completed;

[0078] The treatment method is to excavate according to the design size, and it is required to be connected to the original foundation, but the original foundation cannot be damaged. The foundation reinforcement mesh, reinforcement cage and column reinforcement are arranged in the lateral foundation, i...

Abstract

The invention relates to a renovation method for adding floors to an old building which can improve the earthquake resistance capability and safe life span, and belongs to the renovation method for improving the earthquake resistance capability, safety and lifespan of a building by using structural modification technology, and can also increase floors at the same time. Including the calculation of the size and position of the foundation, columns, and beams according to the actual load after the renovation, according to the conventional frame building structure, the installation of columns and additional floors in the wall, and the demolition of the concrete. The structure becomes a frame structure, the wall and the frame are integrated, and the bearing capacity and earthquake resistance have been greatly improved. The advantages are: the effect of the remodeled house is excellent, the brick structure is converted from the structural modification to the frame structure, the usable space of the house is excellent, the structural safety is greatly improved, the earthquake resistance capacity and service life are also greatly improved, and the users are extremely satisfied.

Description

technical field [0001] The invention belongs to the transformation method of improving the anti-seismic ability, safety and service life of a building by using the structural modification technology, and can increase floors at the same time. Background technique [0002] When renovating old houses, if the performance, earthquake resistance, durability and safety can be improved at the same time, it is very popular and pursued by users. At present, for the existing houses with the following simple structure: that is, including the masonry foundation, the outer wall and the roof, if the house is lifted high enough, it is hoped to improve the use capacity and scope through transformation, and expand the area and use space. Most of the effective and practical transformation methods choose to demolish and rebuild, because adding indoor columns will result in too many indoor columns, which is inconvenient to use and does not improve the structural safety. The floor structure is in...
