Description

A kind of two-way floor of overlapping concrete reinforcement ring
Technical field
The invention belongs to technical field of buildings, more particularly to a kind of two-way floor of overlapping concrete reinforcement ring.
Background technique
A kind of preferable structure type that laminated floor slab is prefabricated and cast-in-place concrete combines.Precast prestressed thin plate (thickness 5 ~8 centimetres) with top cast-in-place concrete layer be combined into an entirety, work together.The prestressing force main reinforcement of thin plate is overlapping The main reinforcement of floor, top concrete cast-in-situ layer only configure negative reinforcement and distributing bar.Prestressed thin slab is used as cast-in-place coagulation The bed die of soil layer, it is not necessary to be in-situ layer support shuttering.Thin plate bottom surface is smooth, and after processing, ceiling can be smeared no longer plate stitch Ash.This laminated floor slab has globality, the rigidity of cast-in-situ floor are big, crack resistance is good, do not increase reinforcing bar consumption, save template etc. Advantage.Since cast-in-situ floor is not required to formwork, there are also bulk precast concrete partition plates to lift simultaneously in the structure construction stage, from And it can be inserted into fitting-out work in advance, shorten the duration of entire engineering.
Floor span can be widely used in hotel, office building, school, house, hospital, warehouse, parking lot, more within 8 meters The various building engineerings such as layer industrial premises.Prestressed thin slab is different by the construction of superposed surfaces, can be divided into three classes: 1. superposed surfaces The shear stress of receiving is smaller, and superposed surfaces do not set shear reinforcement, but requires coarse concrete upper surface, stroke hair or stay some combinations Hole.2. the shear stress that superposed surfaces are born is larger, thin sheet surface will also add shear reinforcement in addition to requiring coarse stroke of hair, and reinforcing bar is straight Diameter and spacing are computed determination.The shape of reinforcing bar has waveform, spiral shape and spot welding mesh sheet to be bent into triangular section.3. prefabricated Thin plate upper surface is equipped with steel truss, to reinforce rigidity when sheet construction, reduces the support that thin plate is set up below.
Reinforced concrete slab is a part of iterative structure, is a kind of prefabricated and cast-in-place structure type combined.It is folded In the construction process, first in basis rest prefabricated panel, it plays template when pouring upper layer concrete to plywood, and then two Part concrete forms entirety and carrys out bearing load.Laminated floor slab integrates cast-in-place and prefabricated advantage, is that one kind has development very much The floor form of future.
1) from stress, for full prefabricated slab, the overall stiffness and anti-seismic performance of structure can be improved, When configuring same presstressed reinforcing steel, for the load action tension edge of total cross-section, established on prefabricated section Effective prestress is larger, to improve the cracking resistance of structure.Under the premise of same cracking resistance, then pre- answer can be saved The dosage of power muscle.
2) from manufacture craft, the main part of the force of laminated floor slab is manufactured in factory, and mechanization degree is high, is easy to protect Quality is demonstrate,proved, it is fast using continuous productive process speed of production, and can make in advance, it does not account for the duration, and the template of pre-erection can To reuse.Pouring concrete does template with prefabricated panel afterwards, and more full cast-in-situ floor can reduce the workload of formwork, and reduction is applied Work situ wet operation improves construction site condition, improves construction efficiency, especially under conditions of high altitude operation or difficult formwork Effect is even more obvious, and prefabrication is easily achieved the production of more complex section form, for developing component load-bearing potentiality, Reducing dead load has apparent advantage.Large span superimposed sheet also is compliant with the developing direction of Modern Residence superstructure simultaneously.
3) long-term scientific experiment and engineering practice result show to take in concrete structure engineering using laminated floor slab Fairly obvious benefit is obtained, when using high strength cast iron, amount of reinforcement is substantially reduced.It, can be with when using prefabricated section on an empty stomach Concrete amount is saved, the duration also shortens accordingly, it, which is disadvantageous in that, increases prefabricated processing and transporting and hoisting link.
4) reinforced concrete slab section is made of prefabricated and cast-in-place two parts, their common working performances are dependent on new The shear behavior of old superposed surfaces, therefore shear bond strength design is very important part, it is seen that reinforced concrete slab is to applying Work technology content also has a higher requirement, especially in construction quality management aspect to using unit to propose tightened up requirement.
5) two-way slab of concrete folding plate be always there are some problems not to be solved effectively, to handle it is various not With the reinforcing bar of form, it is difficult to realize mechanization, the production of intellectually and automatically.Therefore need to solve these technical problems, with Fully demonstrate the advantage of precast concrete assembly building.Two-way slab difficulty of processing is big, at high cost, is often difficult to realize, and without Ji.
Summary of the invention
