Description
Technical field
The present invention relates to a kind of preparation method and application thereof of the truss-like reinforcing bar with circular hole, belong to structure construction technology field.
Background technology
Concrete profiled rod structure has do not reveal post angle in building function, and the feature such as Lateral resisting ability is strong in structural performance, is a kind of form of structure meeting modern architecture developing direction and trend, deeply favors by user.A large amount of theoretical and experimental investigations and engineering practice show, concrete profiled pile structural seismic performance is undesirable.2006, the concrete profiled pile tecnical regulations regulation of country's issuing and implementation, 8 degree (0.2g) area, Framed Structure with Special-Shaped Columns maximum height was only 12m, and this regulation causes difficulty to concrete profiled rod structure applying of highlight lines area.The foundation of this regulation is that the research carried out in industry authorizing standard process finds, ultimate bearing capacity of joints deficiency is the undesirable major embodiment of concrete profiled pile structural seismic performance, and this also becomes the governing factor of the maximum maxi-mum height of the concrete profiled rod structure in highly seismic region.Difficulty is applied in highlight lines area for solving concrete profiled rod structure, the scholar of Some Domestic colleges and universities and R&D institution proposes a lot of measure for the improvement of special-shaped column structure anti-seismic performance, such as adopt steel reinforced concrete special-shaped columns, adopt base isolation, node area adopts high-strength concrete, node area haunch, node area adds shaped steel reinforcing bar etc.Adopt this Study on Measures achievement of steel reinforced concrete special-shaped columns maximum, effect is also better, but cost is higher; The achievement in research of base isolation mode is adopted mainly to concentrate on theory analysis aspect; Node area adopts high-strength concrete measure to have some improvement to concrete profiled pile structural seismic performance, but adopts high-strength concrete to cause ductility of joint to be deteriorated; The achievement in research of node area haunch is less; The measure that node area adds shaped steel reinforcing bar improves successful to concrete profiled pile structural seismic performance, cost is lower, it is a kind of economically viable measure, but node area adds shaped steel reinforcing bar can bring certain difficulty to node construction, be mainly reflected in common steel flanged beam shaped steel reinforcing bar and add membership blocking-up beam column longitudinal reinforcement passing in node area, node area stirrup construction simultaneously also can be hindered.In addition, find in theory analysis, under seismic loading, only node area adds shaped steel reinforcing bar and there will be shaped steel reinforcing bar deficiency bonding with between concrete, there is the mutual changing of the relative positions, cause the problem of constructional difficulties and bonding deficiency after adding shaped steel reinforcing bar for node area, the present invention proposes a kind of truss-like reinforcing bar improving the band circular hole of the construction of concrete profiled pile structure node and enhancing reinforcing bar and concrete bonding.
Summary of the invention
The technical problem to be solved in the present invention is: the present invention is directed to special-shaped column structure and add in node area common steel flanged beam shaped steel reinforcing bar can increase difficulty and reinforcing bar and concrete bonding deficiency problem to construction, propose a kind of preparation method and the application that improve the truss-like reinforcing bar of the special-shaped column structure node construction band circular hole bonding with reinforcing bar with strengthening node area concrete, by processing the shaped steel reinforcing bar adding node area, form the truss-like reinforcing bar of band circular hole, under the prerequisite not increasing cost, not only facilitate node construction, enhance bonding with between reinforcing bar of node area concrete, and do not affect even be conducive to Seismic Behavior promote.
Technical solution of the present invention is: a kind of particular content of preparation method of the truss-like reinforcing bar with circular hole is as follows:
First according to hetermorphiscal column Types of nodes, processing reinforcing bar front end limb plate 1, rear end shaped steel and limb bar 3; According to hetermorphiscal column node area number of steel bars and distribution situation, determine quantity and the distribution of circular hole 4 on front end limb plate 1; Then carry out circular hole 4 to process; Again according to hetermorphiscal column Types of nodes, front end limb plate 1 and rear end shaped steel to be welded as a whole the truss-like reinforcing bar being formed and be with circular hole by limb bar 3.Spacing wherein between front end limb plate 1 with rear end shaped steel must ensure that corresponding beam steel all can pass, but considers from load transmission between front end limb plate 1 and rear end shaped steel, and spacing between the two should be not excessive yet, therefore between the two apart from the half of getting corresponding deck-siding.
Another object of the present invention is that the truss-like reinforcing bar of the band circular hole preparation method of the truss-like reinforcing bar of described band circular hole obtained is applied to and improves special-shaped column structure node construction and strengthen the bonding of node area concrete and reinforcing bar.
When the truss-like reinforcing bar of described band circular hole uses, the lifting of the truss-like reinforcing bar of the band circular hole made to bean column node place, truss-like reinforcing bar with circular hole should be placed on the central authorities of beam cross-section, during colligation beam reinforced steel bar, according to reinforcement construction figure, longitudinal reinforcement and the stirrup that node area need be run through front end limb plate 1 can not be truncated through circular hole 4 reserved on front end limb plate 1 and the joint gap front end limb plate 1 and rear end shaped steel, meanwhile, the reinforcing bar of circular hole 4 and front end limb plate 1 and rear end shaped steel joint gap is run through as the peg retraining reinforcing bar slippage.
The front end limb plate 1 of truss-like reinforcing bar is attacked and bores circular hole 4, circular hole 4 is attacked and bored principle is ensure that the reinforcing bar that hetermorphiscal column node area runs through front end limb plate 1 can not be truncated by design drawing construction, at least large than the diameter the running through front end limb plate 1 reinforcing bar 2mm of circular hole 4 diameter, to guarantee the through smoothly of reinforcing bar in work progress.
The invention has the beneficial effects as follows:
1, truss-like reinforcing bar node shaped steel reinforcing bar being made as band circular hole is conducive to node area reinforcing bar and passes, and ensure that the continuity of beam main tendon, facilitates node construction; Circular hole 4 on front end limb plate 1, as the passage of node stirrup and floor bar, ensure that smooth construction and the structural specifications of node area stirrup and floor bar.
2, node shaped steel reinforcing bar is made as the truss-like reinforcing bar of band circular hole, not only can not weakens the effect that node adds shaped steel reinforcing bar, also can promote the anti-seismic performance of node to a certain extent.Beam main tendon, in the continuity of node area, ensure that beam main tendon is in the stressed continuity of node area; The circular hole 4 of limb plate as node area floor bar and stirrup through passage, strictly can carry out reinforcement construction by designing requirement, ensure that construction quality, simultaneously, the shear stud shaped steel reinforcing bar and concrete is can be used as through the floor bar of circular hole 4 and stirrup, prevent the Relative sliding between steel reinforced concrete, increase the globality of joints.
3, front end limb plate 1 and the rear end shaped steel of being with the truss-like reinforcing bar of circular hole weld by limb bar 3 entirety formed, and easy to make, cost is lower.
