The brick wall body infilled wall structure is an important component part in ancient architecture, and the masonry structure has poor earthquake resistance and is easy to collapse. After the earthquake, a great number of cracks often appear in the masonry structure house, and wall damage and even collapse are easily caused. Therefore, the wall body is reinforced, the lateral bearing capacity is improved, and the service life is prolonged, so that the method has important significance for protecting the ancient masonry building.
Masonry walls generally bear both in-plane loads (dead weight, loads transferred from superstructure) and out-of-plane loads (wind loads, self inertial forces from seismic action). Because of the low tensile strength of the masonry structure and the limited deformability outside the surface, the collapse damage outside the surface becomes a main damage mode of the masonry structure under the action of an earthquake, so that the horizontal bearing capacity of the existing important unreinforced wall body is reinforced, and the improvement of the out-of-plane earthquake resistance is quite important.
In the existing reinforcing method, the out-of-plane strength of the wall body can be remarkably improved by sticking fiber reinforced polymer (CFRP) on the surface of the wall body, but the structure reinforced by the CFRP is easy to generate brittle fracture, the ductility of the reinforced wall body is poor, the shearing resistance and the fire resistance are poor, and in addition, the manufacturing cost is high. The traditional reinforcement method mainly adopts a steel wire mesh cement mortar method, and adopts a thin layer structure formed by taking a steel wire mesh or a steel wire mesh and a steel bar mesh as reinforcing materials and taking cement mortar as a base material. The steel wire mesh can improve the structural strength, and the mortar plays roles of protection and anchoring, but the construction process is complex and troublesome.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the invention provides a plane external reinforcing device for a brickwork filling wall in a traditional wood structure, which comprises a bar wood 1, bolts 2, a rubber pad 3 and a connecting piece 4.
The wood strips 1 can be a plurality of blocks, but generally have an even number, are in a horizontal trend, are parallel to the wall surface of the brick masonry infill wall 5, are symmetrically arranged on the front surface and the back surface of the brick masonry infill wall 5, and have a certain gap between the plate surface and the wall surface. Two strips 1 which are symmetrical on the front and back sides of the masonry infill wall 5 can be referred to as a pair.
