A prestressed fixed deflection structure applied to timber frame and its construction method

Abstract

The invention relates to a prestressed fixed deflection structure applied to a wooden structure frame, comprising a plurality of columns supported on the building ground, the plurality of columns form a support frame, each column is provided with a hoop, and two adjacent columns The upper hoops are mutually tensioned by prestressed steel wires, and at least one outer hoop of the support frame is connected to the external fixed end by prestressed steel wires. The structure of the prestressed fixed deflection structure applied to the wooden frame is simple. The two adjacent columns are connected to each other through the prestressed steel wire, and finally the entire support frame is connected to the external fixed end, which improves the overall structure of the frame. Rigidity, stability and anti-tilt ability of the column, simple and convenient operation, stable structure and low cost.

Description

technical field [0001] The invention relates to a prestressed fixed deviation structure applied to a wooden structure frame and a construction method thereof. Background technique [0002] In the history of Chinese architecture, the wooden structure of ancient buildings is undoubtedly an important chapter. In the long river of history, the wooden structure runs through the past and the present, and is an important contemporary building material and structural form. The wood structure has the characteristics of light weight, convenient materials, simple construction process and fast construction speed. However, after a period of use, the structural performance of the wood itself will degrade, especially the natural defects of the wood, such as knots, insects, When decaying, the degradation of performance will become more obvious, so the wooden structure needs to be reinforced. [0003] At present, the common reinforcement methods for inclined wooden structure columns mainly ...

Problems solved by technology

These methods can improve the lateral stiffness, overall stiffness and bearing capacity of the wooden frame to a certain extent, but these methods still have disadvantages: the overhaul of the falling frame requires a lot of work, the cost is large, the construction period is long, and for ancient buildings, it will cause damage. The value of cultural relics is lost; during construction, the tile roof must be removed first, the watchboard and some rafters must be removed, and the mortise and tenon gaps at the rubbing ends shall be cleaned, so the workload is relatively large; plywood walls and buttress walls shall be added Although the lateral stiffness is improved, it does not improve the overall stiffness, and has a great impact on the cultural relic value of the original structure; the addition of a steel frame takes up a lot of space and damages the aesthetics of the ancient wooden structure

[0004] When the damage of the column is not serious and the column itself has not started to tilt, but the direction of its tilt can be judged by the signs of damage, it is too overkill to use the above method for reinforcement. On the one hand, it wastes manpower and material resources, and on the other hand, it is even more damaged. Construction; when the column itself is not damaged, but you still want to carry out insurance reinforcement, the above method cannot be used
