Abstract
A honeycomb steel beam rib concrete laminated slab comprises a concrete floor and at least one honeycomb steel beam arranged in the slab length direction. Each honeycomb steel beam comprises a top flange, a bottom flange and a steel web, the bottom flanges are embedded in the concrete floor, and the steel webs are provided with honeycomb holes. In-situ casting of concrete is convenient in the construction stage, and the honeycomb steel beam rib concrete laminated slab is reasonable in stress, light in self-weight and high in bearing capacity in the use stage and is an ideal structural member. With the honeycomb steel beams, the rigidity and strength of a prefabricated slab are improved, the weight of the laminated slab is reduced, and use of a temporary support in the construction stage is reduced or avoided. The honeycomb steel beams are flat beams hidden in the concrete floor and bear external loads together with the concrete floor in the later use stage. By adopting honeycomb steel beam ribs, the bonding strength of new concrete and old concrete is improved.
Description
Technical field
The present invention relates to building structure technology field, particularly to a kind of Steel Castellated Beams rib concrete folding plate.
Background technology
Reinforced concrete laminated floor slab is to add a kind of assembling entirety poured one layer of cast-in-place concrete and formed on precoated plate
Formula floor.Assembled integral floor integrates cast-in-situ floor and the advantage of assembled floor, compared to cast-type floor, this building
Plate achieves pre-erection industrialized production, can reduce formwork and concrete construction wet trade amount, shortens construction period；Compared to
Assembled floor, the prefabricated panel of this floor and top cast-in-place concrete are combined into an entirety, floor integral rigidity and antidetonation
Performance all greatly improves, therefore for the larger multi storied industrial factory building of some loads, skyscraper and has requirements for fortification against earthquake
Building, may also be employed this version.
Concrete folding plate can be divided into plane to overlap according to the cross sectional shape of concrete floor and last layer contact surface
Plate, shear connections type superimposed sheet and floor type superimposed sheet three class with ribbing.Viscous between its planar-type superimposed sheet new-old concrete
Knot power is relatively low, and new-old concrete easily ftractures and safety problem occurs, and the rigidity of this kind of superimposed sheet is relatively low, and the construction stage needs
Setting temporary support, increased workload；Shear connections type superimposed sheet arranges bar dowel or reinforcing bar in plane plate upper surface
The shear connector of the types such as truss, enhances the cohesive force of new-old concrete, but the steel using amount of this kind of superimposed sheet is higher, many
Reinforcing bar is in the later stage invalid waste causing steel, and prefabricated thickness of slab is thicker, stacks, transports inconvenience；Floor type overlapping with ribbing
Plate arranges unidirectional or two-way helping in rectangular base plate and is formed, and the rib of prefabricated base plate with ribbing not only increased the rigidity of base plate, subtracts
Less or avoid the use of temporary support, and increased the cohesive force between new-old concrete and shearing strength.Therefore such
Plate has the features such as easy construction, short time limit, cost economic.
The rib of common floor type superimposed sheet with ribbing is xoncrete structure, and cross sectional shape is rectangle and two kinds of t type.Fold for this kind
The general deadweight of plywood is larger, and perforate is inconvenient and cavity position easily produces crack, causes the internal flaw of superimposed sheet, this kind of overlapping
During the construction of plate base plate, formwork supporting plate is more, construction inconvenience；Also scholar is had to propose various steel bar girder rib superimposed sheets at present, but existing
Steel bar girder rib superimposed sheet in steel bar girder effect be mainly to increase adhesion strength between new-old concrete, strengthen construction
The rigidity of bench floor, is substantially not involved in after superimposed sheet pours molding in the later stage carrying, causes the waste of steel.
A kind of entitled " a kind of steel web prestressed concrete overlapping disclosed in China Patent No. cn201310297726.1
The superimposed sheet with ribbing of plate ", makees ribbed stiffener using steel web and the concrete edge of a wing, takes full advantage of outside the excellent plane of steel web just
Degree and shear resistance, reduce dead load.But the connection between steel web and concrete floor and the edge of a wing is insecure, especially ripple
Stricture of vagina steel web, and two block concretes are connected by steel web, not only increase the use of template, and increase difficulty of construction.
A kind of entitled " a kind of corrugated web girder steel-flat beam of Combined concrete " disclosed in China Patent No. cn201520173691.5,
Adopt corrugated web girder steel to connect adjacent two pieces of precast slabs in Shear Behavior of R. c. Laminated Slabs, increase precoated plate it
Between and new-old concrete between adhesion strength and shear-carrying capacity, reduce building floor height.But corrugated web girder steel does not have
It is cast in precast slab, during the construction stage, corrugated web girder steel is not involved in carrying, need to arrange temporary support, construction is not
Just.
Content of the invention
For overcoming problems of the prior art, the invention provides a kind of easy to process, safe and reliable, performance
Superior Steel Castellated Beams rib concrete folding plate.This kind of superimposed sheet achieves Steel Castellated Beams rib and uses rank in construction stage and later stage
The effect that Duan Douneng effectively carries.
The present invention solves its technical problem and is adopted the technical scheme that: this kind of Steel Castellated Beams rib concrete folding plate, bag
Include concrete floor and at least one Steel Castellated Beams along the setting of plate length direction, described Steel Castellated Beams include top flange, lower flange
