Description

A reinforcement structure and method for strengthening the connection of walls and columns of ancient residential buildings

technical field

The invention belongs to the technical field of building reinforcement, and relates to a reinforcement structure and a method for strengthening the wall column connection of ancient residential buildings.

Background technique

Our country has a long history, and the ancient Chinese residential buildings are the most distinctive. These houses have a long history, but many of them are still in use today. Most of the ancient residential buildings are wooden frame load-bearing systems. The frame formed by beams and columns plays the main load-bearing role. The facilities play the role of insulation and rain protection. The so-called "the house will not collapse when the wall collapses". This structural form is the crystallization of the wisdom of ancient Chinese craftsmen and a treasure of Chinese history and culture. However, because the enclosure wall is a self-supporting wall, the calculated height is large and the stability is insufficient. Due to reasons such as eccentricity, skewing, or uneven settlement, the wall often collapses due to insufficient stability. Although the collapse of the wall will not cause the entire The failure of the structure, but it will also lead to serious consequences such as personal and property losses in the house. The present invention utilizes the structure of the walls of ancient residential buildings to increase effective connections between the walls and the internal wooden frame columns, so that the walls and the internal frames form effective knots, thereby significantly improving the overall stability of ancient residential buildings and preventing The collapse of ancient residential buildings is of great significance. The invention adopts off-site prefabricated components and on-site assembly-based reinforcement schemes to reinforce the wall-column connection. The invention is a permanent reinforcement method, which has the advantages of no open flame operation on site, simple operation, convenient application, strong practicability, and adaptability. It has the characteristics of wide range of objects and no damage to the ancient residential buildings. It has a broad application prospect for preventing the instability and damage of ancient residential buildings with a large number of areas.

Contents of the invention

Technical problem: The present invention provides a kind of ancient residential building that is suitable for the internal use of wooden frame and external enclosure brick wall, which can permanently improve the overall stability of the ancient residential building and strengthen the wall-column connection of the ancient residential building. method.

Technical solution: The reinforcement structure for strengthening the wall-column connection of ancient residential buildings of the present invention includes a wall, a side column located inside the wall, a corner column located inside the wall corner, a plurality of side column reinforcements arranged at vertical intervals along the side column, and a A plurality of corner column reinforcements arranged at vertical intervals in the corner column, and the side column reinforcements strengthen and fix the side column and the wall as a whole, including U-shaped connectors arranged around the side columns and long connecting plates arranged on the outside of the wall, U-shaped The connector part wraps around the side column along the circumferential direction, and the two ends pass through the wall and are fixedly connected with the long connecting plate; the corner column reinforcement fixes the corner column and the wall corner as a whole, including the L-shaped connector arranged around the corner column and the The short connecting plate on the outer side of the wall corner, the L-shaped connecting piece wraps the corner column along the circumferential direction, and the two ends pass through the wall and are fixedly connected to the short connecting plate.

In the reinforcing structure for strengthening the connection of walls and columns of ancient residential buildings in the present invention, the walls, side columns and corner columns are all original structures in ancient residential buildings.

The reinforcement method for strengthening the wall column connection of ancient residential buildings of the present invention comprises the following steps:

1) Install side column reinforcements at the bottom, middle and top of the side column respectively according to the following method: wrap the side column with the arc part of the U-shaped connector along the circumferential part, and pass the two ends of the U-shaped connector through the wall brick After the slit protrudes to the outside of the wall, a pre-tightening force is applied from the inside to the outside, so that the side column is tightly attached to the inner wall of the wall, and then the long connecting plate arranged close to the outer wall of the wall is fixedly connected to the end of the U-shaped connector;

2) Install the corner post reinforcements at the bottom, middle and top of the corner post according to the following method: Use the arc part of the L-shaped connector to wrap the corner post along the circumferential part, and extend the two ends of the L-shaped connector through the brick joint of the wall After reaching the outside of the wall, apply a pre-tightening force from the inside to the outside, so that the corner column is tightly attached to the inner wall of the wall, and then the short connecting plate that is set close to the outer wall of the wall is fixedly connected to the end of the L-shaped connector;

3) After all the side post reinforcements and corner post reinforcements are installed, press the two ends protruding out of the wall until they are flush with the wall.

After using the wall column reinforcement device of the present invention, an effective connection can be formed between the wall body and the inner frame of the ancient residential building, so that they can work together, which can effectively improve the lateral stiffness of the ancient residential building and improve its overall stability. Extend its service life.

Beneficial effect: compared with the prior art, the present invention has the following advantages:

Many existing ancient residential building reinforcement methods will cause certain damage to the ancient residential building body, and the process is complicated, the cost is high, the scope of application is small, and the reinforcement device will also affect the appearance of the ancient residential building, which seriously affects the normal use of the ancient residential building Features. However, the present invention has the advantages of strong applicability, small and exquisite parts, replaceable parts, simple operation, convenient application, and no damage to the building itself. It utilizes structural features such as brick joints in the walls of ancient residential buildings to form a protective structure between the maintenance wall and the wooden frame. The effective connection enables the wooden frame and the wall to support each other laterally, permanently increases the structural rigidity, improves the overall stability of the ancient residential building, and can effectively prevent the overall instability and collapse of the ancient residential building under earthquake, strong wind and human action.

The reinforcement structure and reinforcement method have broad application prospects in the reinforcement of ancient residential buildings.
