Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment
As shown in attached Fig. 1 and 2, a kind of method of reinforcing mortise and tenon node wooden frame with stirrup, is characterized in that, it comprises the following steps:
First step stirrup 1 is processed: according to pin 2 and wooden frame 3 sizes, and processing stirrup 1, stirrup 1 height is highly identical with wooden frame 3, and stirrup 1 entangles pin 2, and fixed arm is stretched out to wooden frame 3100mm～150mm place in stirrup 1 opening two ends;
Second step stirrup 1 is installed: stirrup 1 is enclosed within to mortise and tenon node 201 places on pin 2, stirrup 1 is fixed on wooden frame 3 with bolt 4.
In the described first step, in the time that pin 2 diameters are less than or equal to 200mm, stirrup 1 thickness is 3mm～4mm; In the time that pin 2 diameters are greater than 200mm and are less than or equal to 350mm, stirrup 1 thickness is 5mm～7mm.
In the described first step, in the time that pin 2 diameters are less than or equal to 200mm, fixed arm is stretched out to wooden frame 3 to 100mm～120mm in stirrup 1 opening two ends;
In the time that pin 2 diameters are greater than 200mm and are less than or equal to 350mm, fixed arm is stretched out to wooden frame 3 to 120mm～150mm in stirrup 1 opening two ends.
In described step I, stirrup 1 is processed into the shape corresponding with pin 2 profiles.
After in described second step, stirrup 1 is enclosed within on mortise and tenon node 201, first hole with Churn drill in selected bolt 4 positions, bore diameter is to wearing the large 1mm～2mm of diameter of bolt 4;
In the time that pin diameter is less than or equal to 200mm, bolt 4 diameters select 8mm～12mm;
In the time that pin diameter is greater than 200mm and is less than or equal to 350mm, bolt 4 diameters are selected 12mm～16mm.
In described second step, before using bolt 4 to connect, respectively increase a pad in both sides, and tight a bolt 4.Getting mortise and tenon node wooden frame floor height is 2600mm, and span is 3600mm; Pin cross section is circular, and diameter is 200mm; Wooden frame cross section is rectangle, width and be highly respectively 100mm and 200mm.Pin adopts dovetail mode to be connected with wooden frame, dovetail length 50mm, tenon width 50mm, tenon tail width 40mm.Top applies constant vertical load, and single pin vertical load is taken as 20kN.Then apply at a slow speed horizontal reciprocating load by MTS actuator, loading speed is 0.3mm/s.After maximum load occurs, along with the increase of distortion, rupture load and corresponding deformation thereof get load drop to maximum load 85% time corresponding load and corresponding deformation.Destroy if tenon appears pulling out in wooden frame, load corresponding while pulling out tenon can be regarded rupture load as.
Test shows, the horizontal bearing capacity peak value of the contrast mortise and tenon node wooden frame of reinforcing is 3.1kN, and horizontal movement is 75.5mm.
Separately get the identical mortise and tenon node of specification wooden frame.Adopt the stirrup of patent scheme of the present invention to reinforce, stirrup height is all 200mm mutually with wooden frame height.Stirrup adopts 5mm steel plate to be processed into annular, coincide with round log post profile, and stirrup is at wooden frame place opening and extend 100mm, and stirrup prolongation is fixed on wooden frame to wearing bolt with diameter 12mm.
Result of the test shows, adopt stirrup to reinforce after the horizontal bearing capacity of mortise and tenon node wooden frame be 6.9kN, horizontal movement is 200.0mm.Hand over respectively contrast wooden frame to improve 123% and 165%.
A kind of method of reinforcing mortise and tenon node wooden frame with stirrup provided by the invention, by stirrup being set at mortise and tenon Nodes, submit rigidity and the bearing capacity of node to, thereby significantly improve anti-seismic performance and the deformability of mortise and tenon node wooden frame, meet subsequent installation instructions for use.
