Description
Technical field
The utility model is related to building structure technology field, more particularly to a kind of Steel Castellated Beams rib concrete folding plate.
Background technology
Reinforced concrete laminated floor slab is to add to pour a kind of assembling entirety formed by one layer of cast-in-place concrete on prefabricated board
Formula floor.Assembled integral floor integrates the advantage of cast-in-situ floor and assembled floor, compared to cast-type floor, the building
Plate realizes pre-erection industrialized production, can reduce formwork and concrete construction wet trade amount, shortens construction period；Compared to
Assembled floor, prefabricated panel and the top cast-in-place concrete of the floor are combined into an entirety, floor integral rigidity and antidetonation
Performance is greatly improved, therefore for the larger multi storied industrial factory building of some loads, skyscraper and has requirements for fortification against earthquake
Building, can also use this structure type.
Concrete folding plate can be divided into plane according to the cross sectional shape of concrete floor and last layer contact surface to overlap
Plate, shear connections type superimposed sheet and the class of floor type superimposed sheet three with ribbing.It is viscous between its planar-type superimposed sheet new-old concrete
Knot power is relatively low, and new-old concrete easily ftractures and occurs safety problem, and the rigidity of this kind of superimposed sheet is relatively low, and the construction stage needs
Temporary support is set, workload is added；Shear connections type superimposed sheet sets 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 for causing steel, and prefabricated thickness of slab is thicker, stacks, transports inconvenient；Floor type overlapping with ribbing
Plate sets unidirectional or two-way help and formed in rectangular base plate, and the rib of prefabricated bottom plate with ribbing not only adds the rigidity of bottom plate, subtracts
Less or the use of temporary support is avoided, and add the cohesive force and shearing strength between new-old concrete.Therefore such
The features such as plate has easy construction, short time limit, cost economic.
The rib of common floor type superimposed sheet with ribbing is concrete structure, and cross sectional shape is rectangle and T-shaped two kinds.This kind is folded
Plywood is typically conducted oneself with dignity larger, perforate inconvenience and cavity position easily produces crack, causes the internal flaw of superimposed sheet, this kind overlapping
Formwork supporting plate is more during the construction of plate bottom plate, construction inconvenience；Current some scholars propose various steel bar girder rib superimposed sheets, but existing
Steel bar girder rib superimposed sheet in steel bar girder effect mainly increase new-old concrete between adhesion strength, enhancing construction
The rigidity of bench floor, is not involved in carrying after later stage superimposed sheet pours shaping, causes the waste of steel substantially.
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 ", ribbed stiffener is made using steel web and the concrete edge of a wing, is taken full advantage of firm outside the excellent plane of steel web
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
Line steel web, and two block concretes connect 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,
Adjacent two pieces of precast slabs are connected using corrugated web girder steel in Shear Behavior of R. c. Laminated Slabs, increase prefabricated board 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, corrugated web girder steel is not involved in carrying, it is necessary to set temporary support during the construction stage, and construction is not
Just.
Utility model content
To overcome problems of the prior art, the utility model is safe and reliable there is provided a kind of easy to process,
The Steel Castellated Beams rib concrete folding plate of superior performance.This kind of superimposed sheet realizes Steel Castellated Beams rib to be made in construction stage and later stage
The effect that can be effectively carried with the stage.
The technical scheme in the invention for solving the technical problem is：This kind of Steel Castellated Beams rib concrete folding
Plate, including the Steel Castellated Beams that concrete floor and at least one are set along plate length direction, the Steel Castellated Beams include top flange, under
The edge of a wing and steel web, the lower flange build-in is in concrete floor, and the steel web is provided with honeycomb hole.
Further, the concrete floor is internally provided with reinforced mesh, and the reinforced mesh carries prestressing force, reinforcing bar
Mesh sheet and the lower surface of the lower flange are welded and fixed.
Further, the quantity of the Steel Castellated Beams is two or more, and the steel web of Steel Castellated Beams is parallel to each other cloth
Put.
Further, the Steel Castellated Beams are used as to be hidden in concrete slab after concrete folding layer is poured bears carrying
The flat beam of power.
Further, the steel web height of the Steel Castellated Beams is not more than the concrete guarantor of top flange, lower flange and reinforcing bar
Covering thickness.
Further, the honeycomb hole shape on the steel web is circular or regular polygon or ellipse.
Further, pre-set and install circuit pipeline in the concrete floor.
