Description

transformation structure of old building brick column

Technical Field

The utility model relates to a transformation structure of kinds of old building brick posts belongs to building reinforcement technical field.

Background

With the development of economy and the acceleration of urban construction pace, the existing building area of China currently exceeds 600 hundred million square meters, and a large number of existing buildings have reduced safety or function decline due to longer service life, potential safety hazards exist or cannot meet the increasingly developed living needs of people. Therefore, the old building must be treated by effective measures such as reinforcement, maintenance and the like to improve the function of the structure and prolong the service life of the building.

The old city building construction is long in the years, the structural style is mostly brick-concrete structure or timber structure, and the girder of a large amount of buildings adopts independent brick column to support, under the horizontal force effect, takes place to collapse easily, consequently need to be to the building that earthquake-resistant bearing capacity and antidetonation measure do not satisfy current standard requirement reform transform. The conventional reinforcing method adopts the outer-wrapped profile steel, cannot form a whole with the brick column, is stressed together, and has an unobvious reinforcing effect.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a transformation structure of kinds of old building brick posts to realize under the condition of the former post of not disturbing, improve the bearing capacity of post by a wide margin, improve anti-seismic performance, thereby accomplish with low costs, efficient mode and reform transform and overcome the not enough of prior art to the reinforcement of brick post.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model discloses a structure is reformed transform to kind of old building brick posts, including old building brick post, the four corners of old building brick post is equipped with L shaped steel skeleton, L shaped steel skeleton and bottom connection pad welding, the bottom connection pad adopts the bolt anchor on the basis, connect through group steel batten board between the adjacent L shaped steel skeleton, L shaped steel skeleton periphery is equipped with group's main muscle, the main muscle overcoat has group stirrup, the last welding of stirrup has the lacing wire, the lacing wire adopts the bar planting mode to be connected with old building brick post, main muscle, stirrup and old building brick post and concrete placement are physically.

In the structure, the cross-sectional dimension of the old building brick column is 240 multiplied by 240 mm-490 multiplied by 490 mm.

In the structure, the groups of steel batten plates are vertically arranged along the L-shaped steel framework, the distance between the steel batten plates is 250-400 mm, the width of each steel batten plate is 40mm, and the thickness of each steel batten plate is 5 mm.

In the structure, the strength grade of the concrete is C30-C50.

In the structure, the main bar is anchored in the foundation in a bar planting mode.

Since the technical scheme is used, compared with the prior art, the utility model, the low cost, the reinforcement transformation to the brick column is accomplished to efficient mode. The utility model discloses a composite construction who comprises angle steel, steel sheet and reinforced concrete when improving the bearing capacity by a wide margin, because the joining of shaped steel improves the anti-seismic performance of brick post by a wide margin. The utility model discloses simple structure, the site operation of being convenient for, and construction cycle is short, and it is convenient to install, passes power clearly and definitely, and the abundant reduction is to housing construction area, building layout and structural damage, and can improve the bearing capacity and the anti-seismic performance of structure by a wide margin.
