Traditional sole plate post-poured strip structure (application number: 201120202782.9), comprise bed course, ater-casting enhancement Layer, waterproofing course, fish tail and waterproof layer and concrete from bottom to up successively, the integrative-structure that wherein enhancement Layer of ater-casting is formed by the steel plate laid along ater-casting length direction instead of original reinforced concrete structure, decreases engineering quantity and labour; After cushion construction completes, only steel plate need be placed by design attitude, easy construction, can lighten one's labor workload greatly, increases work efficiency, and reduces the engineering time.There is following shortcoming in this form of structure: in (1) work progress, ater-casting is in opening-wide state all the time, construction rubbish easily enters ater-casting, produce certain harmful effect to the construction quality of late poured band structure, intensity and durability, the reinforcing bar simultaneously exposed in ater-casting is easily corroded; (2) two sides, ater-casting easily produce penetrating passage, affect the service life of structure.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provide a kind of can the reinforcing bar that stretches out of both sides, available protecting ater-casting, avoid reinforcement corrosion, effectively avoid construction rubbish fall into ater-casting and have the structure of waterproof effect.
This sole plate post-poured strip structure, comprises sole plate, concrete cushion, pre embedded bolt, premade closure plate, rib of slab, waterproof concrete, ater-casting concrete, hydro-expansive rubber and base plate decorative layer; Ater-casting is provided with waterproof concrete, ater-casting concrete, premade closure plate, base plate decorative layer from the bottom up successively; Concrete two sides, described ater-casting are arranged to step-like; The pre-buried screw rod that premade closure plate and sole plate are fixed on the step of premade closure plate soffit; Premade closure plate both sides are provided with hydro-expansive rubber; Sole plate and premade closure plate upper surface are provided with base plate decorative layer.
As preferably: both sides, described ater-casting concrete is arranged to step-like, and upper and lower transverse reinforcement stretches out side, and welds together with the transverse reinforcement of step opposite side respectively.
As preferably: described premade closure plate adopts precast rc slab or steel plate, reserved screw rod through hole on premade closure plate, premade closure plate soffit is provided with rib of slab, and the upper surface of premade closure plate top and sole plate is in same level.
As preferably: described ater-casting concrete and sole plate adopt the concrete of same label.
The utility model has following feature and beneficial effect:
1, the sole plate post-poured strip structure that relates to of the utility model can the transverse reinforcement that stretches out of both sides, available protecting ater-casting, avoids reinforcement corrosion.
2, arranging of premade closure plate plate can keep the clean of inside, ater-casting, foreign material and construction rubbish is avoided to enter in the groove of ater-casting, thus improve construction quality and the durability of structure, simultaneously, after the concreting of ater-casting, the construction of next procedure can be carried out immediately, effectively shorten the construction period.
3, prefabricated reinforced concrete cover plate surrounding and arrange hydro-expansive rubber with screw rod fixed connection place, effectively can improve the waterproof effect of structure.
4, bottom ater-casting, waterproof concrete is set, the waterproof effect of late poured band structure can be strengthened, avoid the underground water of foundation bottom to produce harmful effect to basis.
In sum; adopt the base plate main muscle up and down that this sole plate post-poured strip structure can expose in available protecting ater-casting; avoid simultaneously foreign material and construction rubbish enter ater-casting; play the effect of construction quality, intensity and the durability improving late poured band structure, there is good water resistance simultaneously.
