Description
Technical field
The present invention relates to the site operation worker method of the structural member and the bean column node of reinforced concrete beam column node.
Background technology
Reinforced concrete beam column node is the key position that guarantees structural-load-carrying capacity and ductility, is the important content of seismic design.Because bean column node district reinforcing bar is staggered, the colligation difficulty often causes the spacing of exopodite hoop excessive in the practice of construction; And " well " font hoop of compound stirrup or all seldom colligations of lacing wire; Do not meet design and code requirement, make structure stay serious hidden danger, belong to one of workmanship common fault.
Summary of the invention
The present invention's technical problem at first to be solved provides a kind of prefabricated stirrup tube of reinforced concrete beam column node, and it can reduce the difficulty of construction of said bean column node, improves construction quality.For this reason; The present invention adopts following technical scheme: it comprises by exopodite and interior limb by certain limb apart from being connected to form latticed horizontal limb; Said stirrup tube is provided with the horizontal limb of multi-layer net shape; Have spacing between layer and the layer, the latticed horizontal limb of said multilayer is fused by many vertical rods more than three, and the outer contour shape of said latticed horizontal limb and the shape of cross section of said bean column node are suitable.
The outer contour shape of said latticed horizontal limb can be rectangle, and said vertical rod is separately positioned on four jiaos of said rectangle.The outer contour shape of said latticed horizontal limb also can be circle, and said many vertical rods along the circumferential direction evenly distribute.The outer contour shape of said latticed horizontal limb and size also can be according to different other shapes that are of the shape of cross section of bean column node; Like T shape, L shaped, cross etc.; Vertical muscle passes its inside as long as it can make post, and it is sunk down in the bean column node district along the vertical muscle of post get final product.
The upper end of said vertical rod exceeds the latticed horizontal limb of the superiors,
The lace angle steel is adopted in said vertical rod.
The present invention needing to replace the node stirrup of field fabrication colligation with prefabricated stirrup tube; Operate extremely simply, can reduce bean column node colligation work difficulty and adhering to specification fully, reduce the on-the-spot labour intensity of workman; Improve work efficiency, bean column node district construction quality can be fully guaranteed.The present invention adopts reinforced concrete beam column node stirrup tube to replace traditional colligation stirrup; Because the stirrup tube encloses the hoop effect to concrete; Restraint performance is better, can improve the anti-seismic performance of node greatly, realizes the anti-seismic performance design aim of " strong node, weak member ".
Another technical problem to be solved of the present invention provides a kind of component on site construction method of reinforced concrete beam column node, can use above-mentioned stirrup tube, reduces the difficulty of construction of said bean column node, improves construction quality.For this reason, the present invention adopts following technical scheme: it provides claim 1 described prefabricated stirrup tube, and said job practices may further comprise the steps:
1), column template, beam forms, template die plate installation forming;
2), said stirrup jacket casing is gone into the vertical muscle of post, support the stirrup tube temporarily and make it remain on the bean column node top;
3), the vertical muscle of beam passes through the stirrup tube from the side, supports the vertical muscle of beam temporarily, is inserted in the stirrup of beam, colligation finishes beam stirrup;
4), remove interim support to the vertical muscle of stirrup tube, beam, the stirrup tube slips into the bean column node district, the beam framework reinforcing bar sinks down into design attitude;
5), post is indulged the latticed horizontal limb tighten of the superiors of muscle and stirrup tube.
For solving the problems of the technologies described above, the present invention also can adopt following technical scheme: it provides above-mentioned prefabricated stirrup tube, and said job practices may further comprise the steps:
1), column template, beam bottom board installation forming;
2), said stirrup jacket casing is gone into the vertical muscle of post, the following bean column node district that slides to;
3), the vertical muscle of beam passes through the stirrup tube, the stirrup of colligation beam from the side;
4), post is indulged the latticed horizontal limb tighten of muscle and stirrup tube.
Further, near the vertical muscle of the post of stirrup tube vertical rod, also with the vertical rod tighten of stirrup tube.
Adopt job practices provided by the present invention, can reduce the on-the-spot labour intensity of workman greatly, improve work efficiency, bean column node district construction quality can be fully guaranteed, and can improve the anti-seismic performance of node greatly.
