Description
Technical field
The present invention relates to precast slab combination beam fields, and in particular to a kind of assembled Fast Installation combination beam.
Background technique
Steel-concrete composite beam forms whole force structure by the shear connector between girder steel and concrete slab, this
Structure has given full play to the material property of steel and concrete, accept rationally, economy it is superior, at home and abroad obtained widely answering
With.
Bridge assembling can realize live Fast Installation, and energy conservation and environmental protection of constructing reduces labor intensity.Steel structure bridge is suitable
Batch production manufacture, industrialized production, fabricated construction.
Steel reinforced concrete combined beam structure is to realize assembling at present, mostly uses cluster formula WELDING STUDS and prefabricated bridge, and cast-in-place
Floorings compare the field operation amount that can reduce, but shear notch and still need to cast-in-place concrete, expend a large amount of manpower.Due to concrete
Age is longer, and cast-in-place concrete need to increase the construction time, and live notch maintenance quality is not easy to guarantee.
Summary of the invention
The object of the present invention is to provide a kind of assembled Fast Installation combination beams, and assembling degree is high, and maintenance quality is more
Easily guarantee, it is convenient to construct, and scene Fast Installation can be achieved under conditions of meeting combination beam mechanical property.
The technical scheme adopted by the invention is as follows:
Assembled Fast Installation combination beam, it is characterised in that:
The combination beam includes the girder steel of precast concrete floorings and the setting of its bottom surface；
Girder steel top surface is welded with WELDING STUDS and casting concrete block, is inserted into precast concrete floorings corresponding position from lower section
The notch of setting is adhesively fixed with precast concrete floorings by grouting material.
Girder steel is I-shaped or groove profile girder steel, and WELDING STUDS is welded in its top board surface.
The WELDING STUDS is cluster formula WELDING STUDS, is decorated in array in the top board surface of girder steel.
Cluster formula WELDING STUDS is embedded in concrete block in advance, and concrete block is located at girder steel top board surface, and whole is in cuboid.
Cluster formula WELDING STUDS longitudinally disposed multiple groups on girder steel form muti-piece concrete block, precast concrete floorings
Notch is correspondingly arranged.
Multiple tracks is arranged in parallel in precast concrete floorings bottom surface in girder steel.
The concrete block of steel beam surface is from before the notch of lower section insertion precast concrete floorings, concrete block and notch
Bonding is realized there are gap and by grouting material.
The invention has the following advantages that
Concrete block is prefabricated using batch production at girder steel and cluster formula WELDING STUDS of the invention, and construction quality mores easily guarantee, and is protecting
Reduce field operation amount under the premise of card structure stress；Floorings and girder steel, which can separate, to be lifted, and lifting weight is reduced；Girder steel and
It is attached between concrete slab by pouring into grouting material between concrete block and notch, connection can be reached in the shorter time
Required intensity reduces the construction time, improves construction efficiency.

Specific embodiment
The present invention will be described in detail With reference to embodiment.
The present invention relates to a kind of assembled Fast Installation combination beam, the combination beam includes 4 He of precast concrete floorings
The girder steel 1 of its bottom surface setting；1 top surface of girder steel is welded with WELDING STUDS and casting concrete block 2, is inserted into concrete from lower section
The notch of native 4 corresponding position of floorings setting is adhesively fixed with precast concrete floorings 4 by grouting material 3.
Girder steel 1 is I-shaped or groove profile girder steel, and WELDING STUDS is welded in its top board surface.The WELDING STUDS is that cluster formula is cut
Power nail 5, is decorated in array in the top board surface of girder steel 1.Cluster formula WELDING STUDS 5 is embedded in advance in concrete block 2, concrete block 2
Positioned at 1 top board surface of girder steel, whole is in cuboid.
According to actual needs, the longitudinally disposed multiple groups on girder steel 1 of cluster formula WELDING STUDS 5 form muti-piece concrete block 2, in advance
The notch of concrete slab 4 processed is correspondingly arranged.Multiple tracks is arranged in parallel in 4 bottom surface of precast concrete floorings in girder steel 1.
The concrete block 2 on 1 surface of girder steel is inserted into the notch of precast concrete floorings 4, concrete block 2 and notch from lower section
There is gap before and bonding is realized by grouting material 3.
When construction:
Girder steel 1 is segmented to be made in factory, cluster formula WELDING STUDS 5 is welded in 1 top flange of girder steel by design requirement, on girder steel 1
The edge of a wing binds template and casting concrete block 2, is transported to construction site after concrete coagulation hardening.Floorings use factory segment
It is prefabricated, notch is reserved by design requirement.
Floorings are lifted after the completion of live steel girder erection, concrete block 2 is made to be located at notch middle position, after the completion of lifting
Notch pours grouting material in gap, and bridge next step construction procedure can be carried out after grouting material reaches intensity.
The contents of the present invention are not limited to cited by embodiment, and those of ordinary skill in the art are by reading description of the invention
And to any equivalent transformation that technical solution of the present invention is taken, all are covered by the claims of the invention.
