Description

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

Technical field

The invention belongs to field of civil engineering, be specifically related to a kind of reserved last-cost joint assembled integral reinforced concrete Tulou Plate.

Background technology

Current in-situ reinforced concrete slab, work on the spot amount is big, and the engineering time is long.And at current assembled coagulation In soil structure, floor many employings laminated floor slab, its advantage is to reduce shuttering work amount, reduces wet trade, improves work efficiency, Shorten construction period, but at present laminated floor slab yet suffers from that prefabrication rate is low, general thickness big, caused by truss bars The unfavorable factors such as amount of reinforcement is many, thus cause laminated floor slab construction costs high, dead load is big and then causes structural earthquake to make By shortcomings such as increasings.

Summary of the invention

The present invention provides a kind of reserved last-cost joint assembled integral reinforced concrete floor, prefabricated rate height, good integrity, mixes Consumption is few, dead load is light for solidifying soil.

Technical scheme is as follows:

A kind of reserved last-cost joint assembled integral reinforced concrete floor, for prefabricated reinforced concrete floor, its periphery sets Postponing pouring concrete plate seam, described rear pouring concrete plate seam uses the mode of on-the-spot arrangement of reinforcement casting concrete to water coagulation after being formed Soil strip.

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

Described reserved last-cost joint assembled integral reinforced concrete floor, its preferred version is, described rear pouring concrete Plate seam cross section is inverted trapezoidal cross 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, described rear pouring concrete In plate seam, configuration reinforcement replaces principle according to equivalent reinforcing bar.

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

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

The invention have the benefit that the reserved last-cost joint assembled integral reinforced concrete floor of the present invention, with cast-in-place Reinforced concrete floor thickness is identical, and its amount of reinforcement is essentially identical with in-situ reinforced concrete slab.The present invention reserved after Water seam assembled integral reinforced concrete floor, the prefabricated rate of assembled floor can be improved, reduce situ wet operation, reduce scene Form work engineering amount, accelerates in-site installation speed, enhances the globality of structure, compared with laminated floor slab, decreases concrete and uses Amount, and then alleviate dead load, reduce the geological process of structure.

Detailed description of the invention

Embodiment 1

As shown in figures 1-4, a kind of reserved last-cost joint assembled integral reinforced concrete floor, for prefabricated reinforced concrete Floor 1, slab thickness is 120mm, concrete and internal calculation the reinforcing bar configured and the pipeline arranged in advance and built-in fitting system Becoming, after utilizing corresponding mould reserved, pouring concrete plate stitches 2 positions, then installation form, layout reinforcing bar and casting concrete；Its Periphery arranges the rear pouring concrete plate seam 2 being perpendicular to edges of boards, and rear pouring concrete plate seam 2 is straight joint form, and spacing is 1000mm, long Degree is the 1/4 of short slab end bay degree；It is inverted trapezoidal cross section that rear pouring concrete plate stitches 2 cross sections, and upper bottom width is 100mm, goes to the bottom a width of 130mm.Prefabricated complete after, can transport to scene carry out lifting install, be overlapped on precast reinforced concrete beam 4.After water Concrete slab stitches and uses the mode of on-the-spot arrangement of reinforcement casting concrete to form rear pouring concrete strip at 2, and rear pouring concrete plate stitches Interior according to equivalent reinforcing bar replacement principle configuration reinforcement 3, at rear pouring concrete plate seam, carry out scene after assembling reinforcement 3 by design and water 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, slab thickness is 150mm, and rear pouring concrete plate seam 2 is Form of grooves, groove bottom concrete thickness of slab is 65mm, and depth of groove is 85mm.
