Abstract
The utility model provides an energy dissipating timber structure tenon-jig node reinforced by arced steel plates. The node comprises a wood post, a wood beam and a tenon-jig node; the wood post is connected with the wood beam by the tenon-jig node; arced steel plates for reinforcing are disposed on the included angle of the wood post and the wood beam; both ends of each arced steel plate are respectively fixed with the wood post and the wood beam by bolts. The energy dissipating timber structure tenon-jig node reinforced by arced steel plates of the utility model, not only has higher bearing capacity, but also has obviously higher energy dissipating ability; can be applied in emergency reinforcing to timber structure tenon-jig nodes after an earthquake, or in earthquake proof reinforcing to common timber structure houses.
Description
Technical field
The utility model 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 curved plate that consumes energy is reinforced, mainly (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 purpose of this utility model 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 curved plate that consumes energy to reinforce, 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 adopted in the utility model is: the wooden construction tenon fourth of the twelve Earthly Branches node that a kind of curved plate that consumes energy 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 curved plate of reinforcement effect, and described curved plate two ends are separately fixed on pin and the wooden frame by bolt.
As preferably, last angle or inferior horn that described pin and wooden frame are connected to form are provided with curved plate.
As preferably, be provided with curved plate simultaneously on last angle that described pin and wooden frame are connected to form and the inferior horn.
As preferably, the material of described curved plate is the steel or the power consumption steel of low-yield.
As preferably, the thickness of described curved plate is 4～8mm.
As preferably, the width of described curved plate is 1/3～1/2 of wooden frame 2 width.
As preferably, the radius of described curved plate is 200～500mm.
As preferably, the diameter of described bolt is more than or equal to 10mm.
The two ends of curved plate described in the utility model 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 beneficial effects of the utility model are: the tenon fourth of the twelve Earthly Branches node that the utility model is reinforced by the power consumption curved plate, and 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 the utility model power consumption curved plate reinforcing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in drawings, the wooden construction tenon fourth of the twelve Earthly Branches node that a kind of curved plate that consumes energy 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 curved plate 4 of reinforcement effect, and described curved plate 4 two ends are separately fixed on pin 1 and the wooden frame 2 by bolt 5.
Described curved plate 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 of curved plate and size all will satisfy certain requirement, to reach the consolidation effect of expection.Curved plate should be made 1/4 circle, and radius is at 200～500mm, and the thickness of curved plate is at 4～8mm, and the width of curved plate is 1/3～1/2 of a wooden frame width.In order to reach better anti seismic efficiency, the material of curved plate can adopt the power consumption material, can be prefabricated in the factory to 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.
