Description
Technical Field
The utility model relates to a building antidetonation reinforcement technology field especially relates to an antidetonation reinforced structure of timber frame building.
Background
In remote areas such as Guangxi and Yunnan China, a lot of rural houses are protected by taking a wood structure as a bearing structure and masonry as a filler wall. According to rural earthquake damage analysis, the earthquake resistance of the wood frame-filled wall structure is poor, the strength of materials in the structure is low, the integral performance is very poor, and the connection performance of the wood frame and the filled wall is poor. The brick wall with the wooden framework of the filler wall only plays a role of enclosure, and because the connection performance of the load-bearing structure and the filler wall is poor, the deformation of the filler wall and the wooden structure is inconsistent, the structure often has the situation of 'the wall falls over the house and does not collapse' under the earthquake action, and the load-bearing capacity and the energy consumption capacity of the load-bearing structure can be effectively improved by reasonably designing the connection of the filler wall and the wooden structure. Under the action of an earthquake, the masonry infilled wall can be subjected to shearing damage in a plane, the masonry infilled wall is very serious in damage and difficult to repair, and is usually required to be dismantled and rebuilt, however, many ancient buildings are also wood frame-infilled wall structures, and in order to protect the ancient buildings, the ancient buildings cannot be dismantled, and are subjected to in-plane reinforcement, so that the anti-seismic performance of the ancient buildings is improved, and the in-plane shearing damage of the ancient buildings is prevented. And the brickwork brick wall also needs to bear the earthquake load outside the plane, makes the central point of brickwork wall take place the building block easily and outwards bulge to the wall, and the plane is outer bending stiffness low and take place to dodge outward easily moreover and lead to the local collapse even the whole collapse. The common reinforcing methods for the wood frame filler wall at present comprise reinforcement embedding, steel wire mesh-polymer mortar reinforcement, external plaster (FRP, steel plate and the like) reinforcement, wall grouting reinforcement, ECC (high-toughness cement-based composite material) surfacing reinforcement and the like. However, the existing reinforcing method only considers a certain failure mode (insufficient connection strength between a wood structure and a wall body, in-plane shear failure and out-of-plane collapse). The seismic performance of the whole wood frame-infilled wall cannot be satisfied.
The earthquake-resistant reinforcing structure of the wood frame building is urgently needed, the connection strength between the wood frame and the masonry brick wall and the shear damage resistance in the plane of the wall body can be enhanced, the block protruding and even collapsing damage outside the plane can be avoided, a lot of materials can be saved, and the engineering cost is greatly reduced.
