Description

A kind of ater-casting structure that adopts the shaped steel short beam to improve shearing resistance
Technical field
The utility model relates to a kind of ater-casting structure, particularly a kind of ater-casting structure that adopts the shaped steel short beam to improve shearing resistance.
Background technology
The length of reinforced concrete beam and plate generally should be provided with the shrinkage joint when surpassing the shrinkage joint maximum spacing of regulation.When helping the ater-casting construction as the weather conditions of construction seasons, can not establish the shrinkage joint, the ater-casting is set on beam slab, the ater-casting width is 800~1000mm, the common way in ater-casting is that the reinforcing bar of beam slab does not cut off, and at an amount of stiffener of beam slab waist configuration.The shortcoming of this way is that the concrete at the old and new's concrete interface can not become integral body and make the shear strength of concrete low, thereby has reduced the shear resistance of beam.Therefore, this ater-casting can only be located at the little position of shearing usually.But, when bigger operation load is arranged at flooring, particularly at the floor that the heavy-duty vehicle operation is arranged, because the shearing that mobile point load (wheel load) causes on beam is bigger, and the position of mobile point load (wheel load) on beam change, and in this case, adopts common ater-casting, just seem and the shear resistance deficiency of beam stay hidden danger to engineering.
The utility model content
The purpose of this utility model is, it is a kind of stressed reasonable that the utility model provides, can bear a kind of ater-casting structure that adopts the shaped steel short beam to improve shearing resistance of big shearing, this structure can improve the shear resistance of place, ater-casting beam greatly, guarantee engineering safety, improve workmanship, and this structural calculation is simple, convenient and quick construction.
The technical solution of the utility model.A kind of ater-casting structure that adopts the shaped steel short beam to improve shearing resistance.Comprise two beam slabs that are oppositely arranged, be embedded with the shaped steel short beam in the beam slab, shaped steel short beam one end is embedded in the beam slab, and the shaped steel short beam other end stretches out outside the beam slab, is provided with the steel concrete ater-casting between two relative shaped steel short beams.
Above-mentioned employing shaped steel short beam improves in the ater-casting structure of shearing resistance, and described shaped steel short beam is provided with one group of lengthways main steel bar that welds together with the shaped steel short beam.
Aforesaid employing shaped steel short beam improves in the ater-casting structure of shearing resistance, be provided with steel bar framework in the described ater-casting, steel bar framework comprises one group of shearing resistance stirrup and one group of side anchor muscle, the shearing resistance stirrup is arranged along the length direction of shaped steel short beam, the side anchor muscle is arranged along the short transverse and the width of shaped steel short beam, and the infall of shearing resistance stirrup and side anchor muscle is connected with the iron wire colligation.
Aforesaid employing shaped steel short beam improves in the ater-casting structure of shearing resistance, and shearing resistance stirrup and side anchor muscle adopt the HRB335 grade reinforcing steel; The spacing of shearing resistance stirrup and side anchor muscle is not more than 200mm, and the diameter of lengthways main steel bar, shearing resistance stirrup and the used reinforcing bar of side anchor muscle is not less than Φ 14.
Aforesaid employing shaped steel short beam improves in the ater-casting structure of shearing resistance, and described ater-casting forms with the concrete casting that label is not less than C25.
Compared with prior art, because the utility model connects beam slab and ater-casting by the shaped steel short beam, can improve the shear resistance of place, ater-casting beam greatly, guarantee engineering safety, improve workmanship, stressed reasonable, and it is simple that this structure also has designing and calculating, the characteristics of convenient and quick construction.
