Abstract

The invention provides an L-shaped angle steel-reinforcing wooden structure tenon-and-mortise node, comprising a wooden column, a wooden beam and a tenon-and-mortise node, wherein the wooden column and the wooden beam are connected through the tenon-and-mortise node; L-shaped angle steel for reinforcing is arranged on an included angle formed by connecting the wooden column and the wooden beam; and two ends of the L-shaped angle steel are respectively fixed on the wooden column and the wooden beam through bolts. By adopting the L-shaped angle steel-reinforcing wooden structure tenon-and-mortise node, the bearing capacity is improved, and meanwhile, the energy consumption capacity is remarkably improved; the product can be used for emergently reinforcing the wooden structure tenon-and-mortise node after an earthquake and can also be used for resisting shock and reinforcing a common wooden structure house.

Description

The wooden construction tenon fourth of the twelve Earthly Branches node that a kind of L type angle steel is reinforced
Technical field
The present invention relates to a kind of building structure, be specifically related to the wooden construction tenon fourth of the twelve Earthly Branches node that a kind of L type angle steel is reinforced, main (but not exclusively) is used for the emergent reinforcing of wooden construction tenon fourth of the twelve Earthly Branches node after the earthquake, also can be used for the seismic hardening of general wooden frame structure.
Background technology
China's timber buildings is with a long history, and distributed areas are wider.From original log cabin in period in ancient times, develop into the modern wood structure of today, the wooden construction form constantly changes.Yet, also exist timber frame load bearing constructions such as a large amount of wooden construction, brick yoke structure and civil structure in vast rural area.These buildings are not passed through regular seismic design mostly, have often caused the loss of a large amount of casualtiess and economic asset in earthquake.Especially at the timber frame load bearing construction that southwest, the high earthquake intensity of northwest earthquake area also exist and have a large capacity and a wide range, danger is big, the serious threat people life property safety is badly in need of reinforcing reparation.
From all previous earthquake the mode of failure of wooden construction as can be seen, its earthquake mainly is divided into: supporting member destruction, destruction of a node, safeguard that body of wall destroys, roofing destroys, integral body is toppled over etc.Wherein common with destruction of a node again, and the harm maximum that causes.Joint form mainly is a tenon fourth of the twelve Earthly Branches node in the tradition wooden construction, and it usually pulls out tenon, folding tenon destruction and fourth of the twelve Earthly Branches mouth destruction etc. in earthquake.Shake back, old place in time reinforces tenon fourth of the twelve Earthly Branches node and seems particularly important.
Tradition wooden construction joint reinforcing mode mainly contains the reinforcing of U sections hoop, dog reinforcing, FRP reinforcing etc.These reinforcing modes all are from increasing the angle of node rigidity mostly, the relative displacement between the limited tenon fourth of the twelve Earthly Branches, thus avoided pulling out tenon, mode of failure such as the beam that falls.Though traditional reinforcing mode is simple and convenient, along with the increase of the integral rigidity of wooden construction, its seismic forces that is subjected to also strengthens thereupon, and these reinforcing modes are between the limited tenon fourth of the twelve Earthly Branches in the relative displacement, and the energy dissipation capacity of wooden construction also descends to some extent.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, the wooden construction tenon fourth of the twelve Earthly Branches node that provides a kind of L type angle steel to reinforce, the tenon fourth of the twelve Earthly Branches node after this is reinforced has also increased energy dissipation capacity when improving supporting capacity, make the anti-seismic performance of wooden construction better.
The technical solution used in the present invention is: the wooden construction tenon fourth of the twelve Earthly Branches node that a kind of L type angle steel is reinforced, comprise pin, wooden frame and tenon fourth of the twelve Earthly Branches node, described pin is connected by tenon fourth of the twelve Earthly Branches node with wooden frame, the angle that described pin and wooden frame are connected to form has been provided with the L type angle steel of reinforcement effect, and described L type angle steel two ends are separately fixed on pin and the wooden frame by bolt.
As preferably, last angle that described pin and wooden frame are connected to form or inferior horn are provided with L type angle steel.
As preferably, be provided with L type angle steel on last angle that described pin and wooden frame are connected to form and the inferior horn simultaneously.
As preferably, the material of described L type angle steel is the steel or the power consumption steel of low-yield.
As preferably, the thickness of described L type angle steel is 6~10mm.
As preferably, the width of described L type angle steel is 1/3~1/2 of a wooden frame width.
As preferably, the length of described L type angle steel is 200~300mm.
As preferably, the diameter of described bolt is more than or equal to 10mm.
The two ends of L type angle steel of the present invention are adjacent to pin and wooden frame respectively, and connect closely with bolt, and the form of described tenon fourth of the twelve Earthly Branches node can be straight tenon, dovetail etc.
The invention has the beneficial effects as follows: the tenon fourth of the twelve Earthly Branches node that the present invention reinforces by L type angle steel, when supporting capacity improved, energy dissipation capacity also had remarkable increase; Product can be used for the emergent reinforcing of wooden construction tenon fourth of the twelve Earthly Branches node after the earthquake, also can be used for the seismic hardening of general wooden frame structure.
Description of drawings
Accompanying drawing is the structural representation of the wooden construction tenon fourth of the twelve Earthly Branches node of L type angle steel reinforcing of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail:
As shown in drawings, the wooden construction tenon fourth of the twelve Earthly Branches node that a kind of L type angle steel is reinforced, comprise pin 1, wooden frame 2 and tenon fourth of the twelve Earthly Branches node 3, described pin 1 is connected by tenon fourth of the twelve Earthly Branches node 3 with wooden frame 2, the angle that described pin 1 and wooden frame 2 are connected to form has been provided with the L type angle steel 4 of reinforcement effect, and described L type angle steel 4 two ends are separately fixed on pin 1 and the wooden frame 2 by bolt 5.
Described L type angle steel 4 can be prefabricated in the factory and finish, and carries out perforate according to bolt 5 diameters, and described bolt 5 is a standard component.
In order to improve the bearing capacity and the energy dissipation capacity of tenon fourth of the twelve Earthly Branches node, the profile and the size of L type angle steel all will satisfy certain requirement, to reach the consolidation effect of expection.L type angle steel length is at 200~300mm, and the thickness of L type angle steel is at 6~10mm, and the width of L type angle steel is 1/3~1/2 of a wooden frame width.In order to reach better anti seismic efficiency, the material of L type angle steel can adopt the power consumption material, can be prefabricated in the factory and finish.The diameter of bolt and number should be calculated definitely according to actual tenon fourth of the twelve Earthly Branches node is stressed, should satisfy the requirement of concerned countries standard simultaneously.
