Description
Technical Field
The utility model relates to a civil engineering technical field, concretely relates to ancient building timber structure house roof beam-brickwork wall connecting portion reinforced structure.
Background
The stone block has high compressive strength and good durability, is a traditional masonry material since ancient times, and is easy to form a traditional masonry process according to the characteristics of local building materials. Houses built by stones are warm in winter and cool in summer and have good living comfort, but most houses are limited by building materials which can be applied in local areas, and are limited by terrains such as mountainous regions and remote mountain areas, cement, sand, stones and other materials are difficult to transport to a construction site, so that the houses can be transported as little as possible. In ancient buildings, mud obtained by adding water into clay and stirring is used as a masonry material and is filled into irregular stone blocks to build a bearing wall, and the masonry method is used up to now. The block shape and size are different, and the block belongs to a bulk material, and because the block and clay have poor adhesive force, caulking soil can fall off along with long-time rain wash, the block constraint is weakened, the wall shear resistance is poor, the bearing performance is seriously reduced under the earthquake action, and the wall can be seriously damaged. The ancient building masonry-wood structure house is more, and the building blocks in the system are regular and irregular, wherein regular building blocks are mostly used for buildings such as palace halls, and irregular building blocks are commonly used for civil houses, and a space stress system formed by wood beams (wood roof trusses) and wall bodies exists.
The structural form of the joint of the wood beam and the block wall is that the beam is placed on the lower layer wall, the structural form determines that the bearing capacity of the beam is often lower than that of a component, the beam is a weak part of the structure, and the beam does not accord with the anti-seismic design principle of a strong node weak rod piece. Because natural disasters reasons such as earthquake, strong wind, in addition timber self material defect will make the timber roof beam can extract and extrude and close on the building block under the timber roof beam recurrence for the timber roof beam jack position grow at brickwork position connects can not hard up, and then arouses to pull off, causes the roof part to drop the frame phenomenon. In order to recover and improve the overall shock resistance of a masonry-wood structure house system, improve the durability of the masonry-wood structure house system and better protect ancient architecture cultural heritage in China, reasonable reinforcement of a connecting part between a wood beam and a wall body in an ancient architecture masonry-wood structure is very important, and the serious damage caused by frame falling and insufficient local pressure bearing of the wall body can be effectively avoided.
At present, the common methods for reinforcing the modern building structure mainly comprise a section enlarging method, a steel plate pasting method, a fiber composite material pasting method, a fulcrum adding method and the like. Due to the particularity of ancient building repair and reinforcement, in order to meet the repair and reinforcement principle of 'minimum intervention, reversibility and identifiability without changing the stress system of the original structure' of the ancient building, the existing reinforcement method needs to be properly improved so as to be suitable for reinforcing the ancient building masonry-wood structure.
The method is characterized in that the damage mode of the existing wall beam system for reinforcing the damaged masonry-wood structure house is analyzed, and the connection part of the wood beam and the wall body is often seriously damaged. The end part of the wood beam is pulled out from the wall body, the wood beam cracks and vertical or oblique cracks appear under the wood beam and close to the wall body. These are all caused by the long-term maintenance, the falling of wall mortar joints or the weathering of building blocks, and the wood beam can be damaged due to the aging of materials, the worm-eating and the like in the natural environment. These damages reduce the overall load-bearing capacity of the structure, leading to local destruction or even continuous collapse of the structure under the action of earthquakes. If the old beam is completely replaced by the new wood, the historical appearance of the ancient building can be damaged, and meanwhile, the problem of further damage caused by failure of connection between the beam and the wall cannot be fundamentally solved. Meanwhile, the stiffness of the old wood beam is changed into a new wood beam, so that the stiffness is not coordinated.
