Description
Technical Field
The utility model relates to the technical field of ancient building reinforcement, in particular to a wooden structure tenon-and-mortise joint reinforcing structure for an ancient building.
Background
The wooden structure of the Chinese ancient building mainly comprises a roof beam frame for supporting a roof, a bearing and anti-side wooden frame and a wall for enclosing and separating, wherein a beam and a column in the wooden frame are connected together through mortise and tenon joints. Completely different from modern steel structure and concrete structure nodes, the tenon-and-mortise joint connection mode is that the section of a joint component is weakened, a tenon is formed at a beam end, a column body is made into a mortise type, and the tenon at the beam end is inserted into the mortise of the column body; the tenon-and-mortise joint mainly depends on mutual extrusion contact between the tenon and the mortise to transfer force, and the contact surface can transfer pressure and friction force but cannot transfer pulling force.
Due to the construction age and environmental change, the ancient building wood structure has different types and degrees of damage under the action of natural and artificial factors such as long-term wind and rain erosion, earthquakes, fire disasters, wars and the like, such as wood aging, component decay, node tenon pulling, column foot decay and the like, so that the bearing capacity of the structure is reduced, and the safety performance and the service life of the ancient building are seriously influenced. According to the special structure of the node, the section of the member is redundant, the safety redundancy is high, but the section of the node is weakened and becomes a weak link of the structure, and after the node fails, the whole structure is easy to become a mechanism and is damaged. Therefore, the wood structure tenon-and-mortise joint is important for performing necessary seismic reinforcement and strengthening and performing the coordination of the joint and the deformation of the connected member on the basis of meeting the ancient building, repairing and strengthening principles.
The traditional reinforcing method of the wooden structure tenon-and-mortise joint of the historic building comprises a tinplate reinforcing method, a steel pin reinforcing method, a flat steel reinforcing method, an FRP reinforcing method and the like. The tinplate reinforced damaged node can limit and delay the occurrence of tenon drawing, and the final damage form of the node is tenon-and-mortise wood local extrusion and the drawing of the tinplate; the effect of reinforcing the damaged node by the steel pin is similar to that of a tinplate, only the tenon pulling is limited, and the problems of low bearing capacity, small rigidity and the like of the damaged node cannot be fundamentally solved; the flat steel reinforcement method usually needs to make wood screws on the wood members for anchoring, when the node rotates greatly, the anchoring failure and damage of the screws can occur, and the wood can be damaged; 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 also has the defects that the bearing capacity of a node cannot be greatly improved and the like. Therefore, the reinforcing method can greatly improve the rigidity and the bearing capacity of the node, can effectively limit the pulling out of the tenon, and prevents the whole structure from being changed into a mechanism and damaged after the node is pulled out of the tenon.
For example, the patent application with application number 200720032298.X discloses "big timber frame's of ancient building timber structure tenon fourth of twelve earthly branches node is consolidated to band steel, including big timber frame, the band steel that timber and timber beam formed through tenon fourth of twelve earthly branches connection, big timber frame's tenon fourth of twelve earthly branches node is consolidated through horizontal band steel, the upper and lower edge of band steel is parallel with the upper and lower edge of timber beam, the band steel passes through the wood screw to be fixed on the timber beam, it is unset between band steel and the timber. In the technology, the wood columns and the wood beams are connected through the flat steel, so that the mutual rotation of the wood columns and the wood beams is limited, and the bending resistance of the mortise and tenon joints is obviously improved; however, in the technology, when the node rotates greatly, the anchoring failure and damage of the wood screw are easy to happen, so that the flat steel is not effective in reinforcement, and the wood is damaged.
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". The carbon fiber cloth is bonded by the organic glue, so that peeling between the carbon fiber cloth and wood is easy to occur, the reinforcing effect is lost before the carbon fiber cloth reaches the ultimate tensile strength, and the improvement of the bearing capacity and rigidity of the reinforcing tenon-and-mortise joint is limited.
The patent application with the application number of 201520792899.5 discloses "an ancient building tenon fourth of twelve earthly branches node that imbedding shape memory alloy stromatolite carbon cloth is consolidated, and this tenon fourth of twelve earthly branches node is consolidated in the post periphery and with the continuous upper and lower stromatolite carbon cloth of wooden beam purlin through two parallel cladding, and the tip of upper and lower stromatolite carbon cloth is equipped with the anchor metalwork of connecting through shape memory alloy respectively, and the metalwork passes through wood screw embedding wooden beam purlin in fixed. The Shape Memory Alloy (SMA) wires are embedded in the laminated carbon fiber cloth, so that the bending resistance bearing capacity and rigidity of the mortise and tenon joint are improved, the energy consumption capacity of the joint is greatly improved, and the reinforcing effect of reinforcing the mortise and tenon joint is further improved. However, in the technology, the anchoring metal piece is fixed by the wood screw unstably, and the anchoring metal piece loses effect after the wood screw is pulled out under stress; and the technology can not limit, and can not effectively prevent serious damage consequences caused by frame falling of a wood structure due to tenon pulling and tenon folding damage of the mortise and tenon joint.
