Description

Wooden structure of ancient building is not hard up tenon joint reinforced structure

Technical Field

The utility model relates to the technical field of historic building timber structure reinforcement, in particular to a reinforcing structure for a loose tenon joint of a historic building timber structure.

Background

The timber structure of the ancient building is characterized in that structural members such as beams and columns are all in a tenon-and-mortise joint connection mode, namely, tenon ends of tenon-and-mortise joints are made into tenon-and-mortise joints, a column body is made into mortise-and-mortise-joint forms, and the tenons are inserted into the mortise-and-mortise joints, so that a concave-convex combined special connection system is formed. However, over hundreds of years of weathering, earthquake disasters and invasion of natural organisms, the mortise and tenon joint often has the damage problems of decay, worm damage, shrinkage crack, joint loosening, tenon pulling-out and the like in different degrees. The damage not only influences the normal work of the mortise and tenon joint, but also potentially threatens the safety of the historic building timber structure.

In various ancient building damage forms, the loose connection of mortise and tenon joints is an important damage characteristic of an ancient building wood structure. According to the structural form of the transparent tenon joint and the assembling technology thereof, the transparent tenon joint is an inserting joint, and a certain initial gap is formed between the tenon and the mortise in order to meet the installation requirement. When the structure encounters hundreds of thousands of years of natural disasters, biological erosion and material drying and shrinkage of the wood, gaps between the tenons and the mortise can be expanded, the contact state becomes poor, and finally the performance of the node is degraded. The transverse grain compressive strength of the wood is known to be along grain compressive strength (1/3-1/10) according to the mechanical property of the wood; therefore, in reality, the deformation of most of loose transparent tenon nodes along the pressed mortise openings of the grains is small, the deformation of the pressed tenon of the transverse grains is large, and the tenon is seriously reduced along the height direction. According to the special structure of the tenon joint, the section of the component is more abundant, the safety redundancy is higher, but the section of the tenon joint is weakened, so that the tenon joint becomes a weak link of the structure; when the tenon joint fails, the whole structure is easy to become a mechanism and be damaged. Therefore, on the basis of meeting the ancient architecture renovation and reinforcement principle, necessary reinforcement is carried out on the loosened tenon joint according to the damage characteristics of the tenon joint, and the recovery joint is particularly important for coordinating the deformation of the connected components.

The traditional ancient building timber structure tenon-and-mortise joint reinforcing method mainly comprises an iron piece reinforcing method, an FRP reinforcing method and the like. The iron part reinforcing method can improve the energy consumption capability of the node by utilizing the excellent ductility of steel; however, the iron parts are easily rusted after being exposed in humid air for a long time, so that the stress performance of steel is degraded quickly, the connection performance between the iron parts is reduced, and most of the reinforced iron parts can damage wood. The FRP reinforcing method has the advantages of light weight, high strength, corrosion resistance, easiness in cutting, convenience in construction, labor saving and the like, but the FRP reinforcing method has the defects that the bearing capacity of a node cannot be greatly improved and the like. In addition, most of the existing reinforcing methods for the mortise and tenon joints are reinforcing and reinforcing, and damaged mortise and tenon joints are rarely reinforced. According to the literature, the tenon variable cross section is easy to tear along the grains under the action of external force such as earthquake and the like, and then the tenon root is broken and the part near the tenon root is bent and damaged. Therefore, the reinforcing method is provided aiming at the damage characteristic of the loose tenon joint, so that the joint recovers the set function, the rigidity and the bearing capacity are greatly improved, the pulling-out of the tenon can be effectively limited, and the problem that the integral structure is changed into a mechanism to be damaged after the tenon of the joint is pulled out and loses efficacy is particularly important.

The application number is 200720032300.3 discloses "a big timber frame's of carbon cloth reinforced ancient building timber structure tenon fourth of twelve earthly branches node, the big timber frame is formed through tenon fourth of twelve earthly branches connection to timber column and timber beam, carbon cloth, big timber frame's tenon fourth of twelve earthly branches node is consolidated through pasting the horizontal carbon cloth on timber column and timber beam, the upper and lower edge of horizontal carbon cloth is parallel with the upper and lower edge of timber beam, horizontal carbon cloth is through the carbon cloth hoop anchor of the perpendicular to timber beam length direction on timber beam". In the technology, the carbon fiber cloth is bonded by organic glue, so that the carbon fiber cloth is easy to peel off from wood, and the reinforcement can lose the effect before the carbon fiber cloth reaches the ultimate tensile strength, so that the improvement of the bearing capacity and the rigidity of the reinforcement on mortise and tenon joints is limited.

The patent application with the application number of 201610141475.1 discloses "a node reinforcing apparatus that ancient building timber structure allows to slide, beam-ends and the column end at tenon fourth of twelve earthly branches node respectively set up the steel component, and the steel component and the roof beam collaborative work on the roof beam, the steel component and the post collaborative work on the post utilize the steel component on the roof beam to retrain the deformation of steel component on the post to make tenon fourth of twelve earthly branches node take place to be retrained by the steel sub-assembly after certain slippage, no longer continue to warp". However, in the technology, the bolt anchor of the fastening reinforcing member is inserted into the wood beam and the wood column to damage the wood structure body, and the bolt anchor on the beam column is easily pulled out, so that the reinforcing device fails.

The application number is 201820004021.4 discloses "an ancient building timber structure tenon fourth of twelve earthly branches node reinforcing apparatus, including wooden beam and post, be equipped with the stop collar on the wooden beam, the post is equipped with fixed cover respectively on wooden beam upside and downside position, is equipped with the extension rod between fixed cover and the stop collar, and the fixed cover that is located the wooden beam upside is connected with the lower extreme of stop collar, and the fixed cover that is located the wooden beam downside is connected with the upper end of stop collar". However, in the technology, the rod piece is easy to be unstabilized under pressure, and the pulling effect is lost after the rod piece is unstabilized, so that the effect of improving the bearing performance of the whole structure by reinforcing the mortise and tenon joint cannot be achieved.

Therefore, aiming at the defects and shortcomings of the traditional method for reinforcing the tenon-and-mortise joints of the wood structure, the reinforcing structure for the loose transparent tenon joints of the ancient building wood structure is urgently needed, and the bending rigidity, the ultimate bearing capacity and the energy consumption capacity of the loose transparent tenon joints can be greatly improved, so that the phenomena that the loose transparent tenon joints are torn along the grain and damaged and are bent are effectively restrained, the ductility of the joints is improved, the tenoning of the loose transparent tenon joints is limited, and the tenon pulling damage is avoided.
