Description
Technical field
The utility model relates to building structure technology field, specially a kind of superimposed sheet composite roof truss.
Background technique
Truss: structure made of one kind is hinged at both ends each other as rod piece.The general tool that truss is made of straight-bar
There are the plane or space structure of triangular element, truss member is primarily subjected to axial tension or pressure, so as to make full use of material
The intensity of material saves material than solid web girder when span is larger, mitigates self weight and increases rigidity.
The advantages of truss is that rod piece is primarily subjected to pulling force or pressure, can give full play to the effect of material, saves material, subtracts
Light construction weight.There are commonly steel truss, reinforced concrete truss, prestressed concrete truss, timber truss, steel to combine purlin with wood
Frame, steel and Combined concrete truss.
In the development process of prestressing force superimposed sheet, the skill to the shearing resistance of conjunction old and new concret face and foolrstiffness experienced
Art requires process from low to high.By the development of many years, prestressing force superimposed sheet by from it is flat to shear reinforcement formula again to
Reinforce the performance that ribbed substantially increases product.However, in the actual production process, the application of ribs reduces production effect
The presentation quality of rate and component is unfavorable for the popularization and application of technology.The application of country's prestressing force superimposed sheet mainly has plate at present
Formula, steel pipe truss formula and concrete ribbed, and steel pipe truss formula is current mainstream.What steel pipe truss formula was primarily present at present asks
Inscribe as follows: 1, steel pipe truss formula rigidity is smaller, and scaffold measure difficulty is big when superimposed sheet is constructed；2, in the steel pipe of steel pipe truss formula
High-strength slightly expanded concrete need to be poured, complex process, production efficiency is low, it would therefore be highly desirable to which a kind of improved technology is existing to solve
This problem in the presence of technology.
Utility model content
The purpose of this utility model is to provide a kind of superimposed sheet composite roof truss, the concrete of filling in C-type steel and slot
Collective effect, very big rigidity is provided to bottom plate, and the variation of C-type steel height meets the requirement of bottom plate different-stiffness, C-type steel
Slot inner concrete pours together with bottom plate, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of superimposed sheet composite roof truss, including C
Fashioned iron and steel bar girder winged, C-type steel lower surface both ends are connected with steel bar girder top winged respectively, the reinforcing bar winged
Truss section is up-side down triangle.
Preferably, the steel bar girder winged includes web member reinforcing bar and the muscle that winds up, and the muscle two sides of winding up are respectively at web member
Reinforcing bar is connected, and web member reinforcing bar upper end is bent outward.
There is choosing, the steel bar girder winged further includes lower edge muscle.
Preferably, the wall thickness of C-type steel is 0.5~4mm.
Preferably, the height of the C-type steel is 50~200mm, and the width of the C-type steel is 30~150mm.
Preferably, the side aperture of the C-type steel, diameter are 4~10mm.
Preferably, the C-type steel inner transverse is provided with reinforcing bar, and the reinforcing bar both ends are respectively arranged at the side of C-type steel
Aperture in.
Compared with prior art, the utility model has the beneficial effects that
(1) C-type steel and the interior concrete collective effect filled of slot, very big rigidity, C fashioned iron height are provided to bottom plate
Variation, meet the requirement of bottom plate different-stiffness.
(2) C-type steel slot inner concrete pours together with bottom plate, improves production efficiency.
Detailed description of the invention
Fig. 1 is the utility model side structure schematic view.
Fig. 2 is the utility model cross section structure schematic diagram.
Fig. 3 is steel bar girder cross section structure schematic diagram winged.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of superimposed sheet composite roof truss, including C-type steel
1 and steel bar girder winged 2,1 lower surface both ends of C-type steel be connected respectively with 2 top of steel bar girder winged, steel bar girder 2 winged is cut
Face is up-side down triangle, and the wall thickness of C-type steel 1 is 0.5~4mm, and the height of C-type steel 1 is 50~200mm, and the width of C-type steel 1 is 30
~150mm, the side aperture of C-type steel 1, diameter are 4~10mm, and the C-type steel 1 that composite roof truss rib uses, steel plate thickness meets weldering
Connect the requirement of power transmission；Truss uses steel bar girder 2 winged, and material is not less than HRB400；The bottom surface of C-type steel 1 and steel winged
The both wings of muscle truss 2 use fillet weld seam, and 1 inner transverse of C-type steel is provided with reinforcing bar 11, and 11 both ends of reinforcing bar are set respectively
It is placed in the aperture of the side of C-type steel 1.
As shown in figure 3, steel bar girder 2 winged includes lower edge muscle 21, web member reinforcing bar 22 and the muscle 23 that winds up, 23 two sides of muscle of winding up
