Description
Technical field
The invention belongs to timber structures to reinforce technical field, and in particular to a kind of construction of timber structure beam column Tenon joint strengthening
Form.
Background technique
The development that Wooden Structure of Chinese Ancient Architecture have passed through thousands of years is perfect, and in China, most area exists and widely answers
With；The connection type of Ancient Times in China tradition timber structure is mainly mortise-tenon joint, which is widely used in building, furniture
And in common wooden utensil, it is convenient that the main feature of mortise-tenon joint is drawn materials, easy construction, quickly.
Although wood-structure old building structural behaviour is superior, there are still certain defects: (1) from building up from it, just will
It is influenced by physics, chemistry and biological factor, causes timber aging, physical and mechanical property decaying, damage accumulation；(1) and
There are the excessive fourths of the twelve Earthly Branches mouthful in mortise-tenon joint, it will usually unfavorable to the stress of entire node；(3) under seismic loading, usually
Will appear it is out of joint, pull out phenomena such as tenon；(4) area is larger after joinery and its construction is interconnected with one another, at section has weakening, in load
Easily occurs the phenomenon that stress concentration under effect, to cause the destruction of component；Based on above-mentioned problem, existing timber structure
Beam column Tenon node usually requires to reinforce.
Currently, the method for common timber structure Tenon joint strengthening can be improved the bearing capacity of node to a certain extent,
But these methods still have deficiency in practical situations: (1) being wrapped beam cross-section using short steel, then will be flat with wooden peg
Steel is scheduled on beam column by force, but the fixed requirement for wooden peg of band steel is high, and complex manufacturing technology；(2) by iron nail directly by tenon
Fourth of the twelve Earthly Branches node is fixed by force, but iron nail will damage structure；(3) beam column is replaced, but destroys timber buildings itself
Historical value；(4) bean column node outer wrapping fiber enhancing composite material is reinforced, but it is complicated to construct, and forms brittleness, and reduce and destroy
Seismic Behavior；(5) fall frame overhaul and beat to prop up and set right, but heavy workload, cost greatly, long construction period and for ancient building meeting
It is set to lose antique value.
Summary of the invention
To solve problems of the prior art, the present invention provides a kind of structures of timber structure beam column Tenon joint strengthening
Appearance formula has the advantages that easy construction, low cost, reinforcing effect are significant.
To achieve the above object, the invention provides the following technical scheme:
1, a kind of structural form of timber structure beam column Tenon joint strengthening is determined including screw rod and being fixed on screw rod
Bit architecture, the location structure include nut, cushion block and gasket；
The screw rod is through the beam being mutually connected vertically, in rod structure, and the cushion block, gasket and nut are with beam, column knot
The flared direction of structure is successively sheathed on screw rod；
The nut is screwed with screw rod to be connect, and is formed and compressed by nut between beam, rod structure and cushion block；
There are four the nut and cushion block are all provided with, and four cushion blocks are divided into two groups of two sides for being closely attached on beam, rod structure respectively
Table wall.
Preferably, the angle that runs through of the screw rod is 45 °.
Preferably, the cushion block uses triangular prism structure, and the cross sectional shape of cushion block is isosceles triangle.
2, it is directed to above-mentioned structural form, installation construction step is as follows:
A) two 45 ° of oblique holes are symmetrically opened up on beam to be reinforced, rod structure, and guarantee the axle center of two oblique holes
Line is located along the same line；
B) screw rod compatible with oblique hole aperture is taken, and guarantees that the length of screw rod is greater than between two oblique holes
Then one end of screw rod is inserted into one of oblique hole by distance；
C) it is inserted in two groups of location structures on screw rod, and guarantees that two groups of location structures are located between two oblique holes；
D) screw rod is continued into, so that another oblique hole is run through in one end of screw rod；
E) to be exposed to beam, one group of location structure is inserted at the screw rod both ends outside rod structure respectively；
F) nut in four location structures being inserted in step c) and step e) is tightened, so that four cushion blocks compress
Four contact surfaces of beam, rod structure are fixed to form reinforcement.
Preferably, the size of the screw rod, nut, cushion block and gasket is determined according to national standard Bolt sizes.
Compared with the prior art, the present invention has the following beneficial effects:
Simple structure of the present invention, it is easy for construction, it occupies little space；It is with strong points using local strengthening, without to beam column structure
Part is replaced, low cost；Timber buildings Tenon node Stiffness problem under long-term natural environment is overcome, is mentioned simultaneously
The high energy dissipation capacity of node, has been obviously improved the anti-seismic performance and overall stiffness of timber structure.
Detailed description of the invention
Fig. 1 is front view of the invention；
Fig. 2 is enlarged drawing at the A in Fig. 1；
In figure: 1- screw rod, 2- nut, 3- cushion block, 4- gasket.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
