Abstract

The invention discloses a method of changing multistory brick-concrete structure building near street into frame structure building. The technical method provides changed building structure project according to owner changing intension and using performance of new building after changed. By calculating the changed total structure project construction drawings of changing and strengthening building structure are drawn. According to construction drawings, foundation underpinning construction and underpinning brick-wall construction of new concrete frame beam-column are carried out. Thereinto, the construction of new concrete frame beam-column structure system adopts reverse process. By adopting the invention existing building is changed and used. Compared with demolishing and rebuilding to existing building, it is provided with no land expropriation, no demolishing, land and social source saving, small invest and quick result. It strengthens the capability that existing building adopts market development and change and improves the usage efficiency of existing building near street. To an extent social economical development is promoted.

Description

Overlooking multistory brick-and-concrete structure building renovation is the method for frame structure building
Technical field
The present invention relates to the remodeling method of building, particularly a kind of method that is frame structure building with overlooking multistory brick-and-concrete structure building renovation.
Background technology
Along with the enhancing and the development of market economy of china's overall national strength, the construction work of China has begun to enter newly-built and has transformed the developing period that maintenance is laid equal stress on.At first, from the social visual angle of present stage, the degree of safety in large quantities of old rooms of building after the founding of the state and dwelling environment all more and more are difficult to satisfy people's the existing standard of living and the needs of social sustainable development, some old room even have serious potential safety hazard.Secondly, along with the quickening of China's process of industrialization, industry restructuring and renewal of the equipment, production technology renewal etc. are increased, and the function in existing house also must adapt to this variation.
Existing all kinds of overlooking multistory brick-and-concrete structure buildings are transformed, make it adapt to the new functional requirement that people propose, satisfy the commercial needs of continuous development and change, rebuild with existing building is removed, there is not expropriation of land, do not have and remove, save soil and social resources, small investment, instant effect, strengthen existing building and adapted to the ability that market development changes, improved the service efficiency of existing overlooking building, promoted socio-economic development to a certain extent.
Summary of the invention
The objective of the invention is deficiency, the method that the overlooking multistory brick-and-concrete structure building renovation that provides a kind of and save the soil, saves social resources, small investment, instant effect is a frame structure building at the prior art existence.
For achieving the above object, the technical solution used in the present invention is: the method that a kind of overlooking multistory brick-and-concrete structure building renovation is a frame structure building is characterized in that this method specifically may further comprise the steps:
(1) transforms intention and transform the new building function of use requirement that back hope reaches according to the owner, propose to transform back building structure scheme;
(2) will transform the level that the back whole structural scheme decomposes member, the improved actual cross-section of structural element of selected various situations; Determine the joint construction of member;
(3) determine to transform back member actual cross-section and rigidity representative section, set up improved monolithic architecture structural model;
(4) carry out structural analysis, draw whole displacement, anti-seismic performance and the reinforced component data of new construction; Carry out the adjustment that building structure is arranged repeatedly, require and the component performance requirement up to the structural seismic overall performance that satisfies the current specifications requirement;
(5), draw and transform the building structure construction drawing of reinforcing by above structural analysis result of calculation;
(6) according to the construction drawing of step (5), at first carry out the construction of ground stabilization and foundation underpinning, promptly wear the method that muscle cooperates concreting, under the situation of not destroying original brickwork bar base, the brick bar base of rigidity is transform as the strip foundation under columns of flexibility by bar planting, boring;
(7) secondly increase the concrete frame beam column bracket newly and change the brick wall construction, promptly at existing structure underfloor installation frame beam column reinforcing bar, install and underpin the frame beam column template, the method that be combined on original body of wall and the floor boring, holes is built to finish and is underpined frame beam column structural system; After the newly-increased frame beam column system that underpins reaches the design strength requirement, remove and underpined body of wall, finish the process that underpins to the existing building brick wall;
(8) in concrete frame post and beam structure system construction, adopts and plant: first underfloor and original structure body of wall side installation beam column cage of reinforcement at original structure with the subinverse workmanship; Install column template again; Build the post concrete; Remove column template; Install beam forms; The casting beams concrete; The frame beam column system of successively having constructed new, and after it reaches the design supporting capacity fully, remove the original structure brick wall that is underpined; Form by the combo box trestle at last, underpin the new frame structure system that beam and original structure floor are formed.
The present invention compared with prior art has the following advantages: adopt the present invention that existing building is carried out renovation and utilization, with being removed to rebuild, existing building compares, have and do not have expropriation of land, do not have the characteristics of removing, saving soil and social resources, small investment and instant effect, strengthen existing building and adapted to the ability that market development changes, improve the service efficiency of existing overlooking building, promoted socio-economic development to a certain extent.
