Description
Technical field
The utility model belongs to technical field of building construction, is specifically related to the composite member in constructional column hole for precast beam.
Background technology
Constructional column, is be arranged in the masonry of building and be connected with beam slab, for building provides the structural member of more useful anti-seismic performance.Along with a large amount of construction of high-rise building, the utilization of constructional column is more and more extensive.Between constructional column and beam slab, by bar planting (by reinforcing bar, both being linked together), interconnect, become fixing integral body.But; bar planting method between existing constructional column and beam slab is after forming the concreting of beam slab and solidifying; the mode that employing is holed to beam slab is carried out bar planting; need to carry out floating dust in fixed point location, boring, removing boring, boring is injected colloid, anchored into reinforcing bar, reinforcing bar proofread and correct, just can complete after solidifying the processing steps such as protection to boring beam slab, also will after the self check of construction party and transfer project acceptance inspection two procedures, just can enter the construction of constructional column subsequently.The deficiency such as have that complex procedures, difficulty of construction are large, low precision, cycle are grown, taken time and effort, in addition, owing to needing that in construction beam slab is holed, this boring is not easy location first, and in the process of punching, be difficult to guarantee that beaten hole is vertical all the time with beam slab end face, affect the structural strength of later process; Second, due to boring, subsidiary high-frequency vibration can cause the deteriorated of inequality that beam slab internal stress distributes and beam and slab structure and intensity, very easily at beam slab opening area, produce radial fine cracks, and have a strong impact on structural strength and the shock resistance of beam slab and even building itself.In order to eliminate above-mentioned impact, increase again extra structure and technique, the waste engineering time also causes the rising of building costs.
If when making beam slab, realize and stayed constructional column hole, can better overcome brought by techniques such as above-mentioned boring, removing, injecting glue, rectification and curing protections loaded down with trivial details and not convenient.Existing trial is the mould that scribbles sliding agent to be placed on to beam slab when making beam slab to make in groove, then topples over concrete, after hardening of concrete, the mould of making beam slab locating hole is removed again.The deficiency that this scheme exists is: when toppling over concrete slurry, easily the lubrication oil on the mould of making beam slab locating hole is washed out, cakey concrete and the mould of making beam slab locating hole are adhered to each other, be difficult to root out.In addition, the access times of the mould that the method is used are limited, after often using several times, when disassembling on the concrete beam plate of mould self-forming, first can residual concrete on mould, second mold rods can produce coarse extension trace with it, all makes follow-up while re-using mould, the concrete of newly building is hung between trace and is closely connected with original residual concrete or shaft, is difficult to after beam slab sizing, mould be removed.
In addition, because beam slab belongs to large-scale block, internal and external temperature differs greatly, after the concrete setting on surface, inner slow setting soil also in higher temperature, still in process of setting slowly.And along with the difference of beam slab thickness and environment temperature, the time of solidifying is different in size.If in advance mould is removed on beam slab, be unfavorable for the sizing of beam slab and constructional column hole, and the quality of beam slab and mechanical strength, toughness are existed to adverse influence.
