Abstract

The utility model belongs to civil engineering field, concretely relates to water integral reinforced concrete floor slab of seam assembly after reservation. The utility model discloses a water integral reinforced concrete floor slab of seam assembly after reservation, is the precast reinforced concrete floor, waters the concrete slab seam after its periphery sets up, after water and water the concrete slab area after mode that concrete slab seam adopted on -the -spot arrangement of reinforcement and concreting forms. The utility model provides a water integral reinforced concrete floor slab of seam assembly after reservation, prefabricated rate is high, the wholeness is good, the concrete quantity is few, structural weight is light.

Description

A kind of reserved last-cost joint assembled integral reinforced concrete floor

Technical field

The utility model belongs to field of civil engineering, and in particular to a kind of reserved last-cost joint assembled integral armored concrete Floor.

Background technology

Current in-situ reinforced concrete slab, work on the spot amount is big, and the engineering time is long.And in current assembled coagulation In soil structure, laminated floor slab being adopted floor, its advantage is to reduce shuttering work amount, reduces wet trade, improves operating efficiency more, Shorten construction period, however at present laminated floor slab yet suffer from that prefabrication rate is low, general thickness is big, by truss bars caused by The unfavorable factor such as amount of reinforcement is more, so as to cause laminated floor slab construction costs high, dead load greatly and then causes structural earthquake to make The shortcomings of with increasing.

Utility model content

The utility model provides a kind of reserved last-cost joint assembled integral reinforced concrete floor, and prefabricated rate is high, globality Good, concrete amount is few, dead load is light.

The technical solution of the utility model is as follows：

A kind of reserved last-cost joint assembled integral reinforced concrete floor, is prefabricated reinforced concrete floor, and its periphery sets Pouring concrete plate stitch is postponed, the rear pouring concrete plate stitch pours coagulation after being formed using live arrangement of reinforcement and by the way of casting concrete Native strip.

Described reserved last-cost joint assembled integral reinforced concrete floor, its preferred version is, the rear pouring concrete Perpendicular to edges of boards, spacing is less than 1200mm to plate stitch, and length is the 1/4 of short slab end bay degree.

Described reserved last-cost joint assembled integral reinforced concrete floor, its preferred version is, the rear pouring concrete Plate stitch section is inverted trapezoidal section, and upper bottom width is less than 120mm, and lower bottom width is less than 140mm.

Described reserved last-cost joint assembled integral reinforced concrete floor, its preferred version is, the rear pouring concrete Configuration reinforcement replaces principle according to equivalent reinforcing bar in plate stitch.

Described reserved last-cost joint assembled integral reinforced concrete floor, it is described when its design thickness is less than 140mm Afterwards pouring concrete plate stitch is straight joint form.

Described reserved last-cost joint assembled integral reinforced concrete floor, when its design thickness is not less than 140mm, institute It is form of grooves to state rear pouring concrete plate stitch, and groove bottom concrete thickness of slab is not less than 60mm, and depth of groove is not less than 80mm.

The beneficial effects of the utility model are：Reserved last-cost joint assembled integral reinforced concrete Tulou of the present utility model Plate, identical with in-situ reinforced concrete slab thickness, its amount of reinforcement is essentially identical with in-situ reinforced concrete slab.This practicality New reserved last-cost joint assembled integral reinforced concrete floor, can improve the prefabricated rate of assembled floor, reduce situ wet Operation, reduces Site Template quantities, accelerates in-site installation speed, enhances the globality of structure, compared with laminated floor slab, subtracts Lack concrete amount, and then alleviated dead load, reduce the geological process of structure.

Specific embodiment

Embodiment 1

As shown in figures 1-4, a kind of reserved last-cost joint assembled integral reinforced concrete floor, is prefabricated reinforced concrete Floor 1, slab thickness is 120mm, by concrete and the internal calculation reinforcing bar for configuring and the pipeline and built-in fitting system arranged in advance Into, using corresponding mould it is reserved after the position of pouring concrete plate stitch 2, then installation form, arrangement reinforcing bar and casting concrete；Its Periphery arranges the rear pouring concrete plate stitch 2 perpendicular to edges of boards, and rear pouring concrete plate stitch 2 is straight joint form, and spacing is 1000mm, long Spend for the 1/4 of short slab end bay degree；Afterwards the section of pouring concrete plate stitch 2 is inverted trapezoidal section, and upper bottom width is 100mm, is gone to the bottom a width of 130mm.After the completion of prefabricated, you can transporting to scene carries out lifting installation, it is overlapped on precast reinforced concrete beam 4.After pour Rear pouring concrete strip, rear pouring concrete plate stitch are formed at concrete plate stitch 2 using live arrangement of reinforcement and by the way of casting concrete Interior to replace principle configuration reinforcement 3 according to equivalent reinforcing bar, by design, the scene of carrying out is poured after assembling reinforcement 3 at rear pouring concrete plate stitch Build, form post-cast strip, constitute reserved last-cost joint assembled integral reinforced concrete floor.

Embodiment 2

As shown in figures 5-8, difference from Example 1 is that slab thickness is 150mm, and rear pouring concrete plate stitch 2 is Form of grooves, groove bottom concrete thickness of slab is 65mm, and depth of groove is 85mm.
