Abstract
The invention relates to a segment prefabrication and assembly beam structure with steel sleeve elastic shear force tenons. A conventional beam prefabricated segment assembly and connection device is usually provided with rigid shear keys, machining is complex, interference between the rigid shear keys and a prestressing force duct is high, and the formwork cost is high. The segment prefabrication and assembly beam structure comprises a box girder type prefabricated beam segment, annular transverse partition plates are arranged on the edges of cavities in the two end faces of the prefabricated beam segment, reserved holes are evenly arranged in each transverse partition plate, and externally-sleeved steel pipes are embedded into the reserved holes; when every two adjacent prefabricated beam segments are spliced, and the internally-sleeved steel pipes corresponding to the externally-sleeved steel pipes in position penetrate into the externally-sleeved steel pipes; axial internally-sleeved pipe kerfs are formed in the internally-sleeved steel pipes, and one end of each internally-sleeved steel pipe is conical. The prefabricated beam segment assembly and connection structure is easy to construct, high in formwork utilization rate, low in beam steel cable interference and even in stress, shear force in the prefabricated box girder segment cementing joint assembly structure is effectively transmitted, and the defects that key blocks and key grooves are prone to damage and tightness is not achieved after vibration are overcome.
Description
Technical field
the invention belongs to bridge engineering construction technical field, be specifically related to a kind of precast segment spliced girder body structure that steel sleeve elasticity shear tenon is set.
Background technology
The assembled construction method of precast segment has intensive, modernization feature; the beam section quality that standardization is made is good, can improve working conditions, and is conducive to the advantages such as environmental protection; add improvement and the development of transport, lifting appliance, the assembled construction method of precast segment is being promoted rapidly all over the world.At present, precast segment assembling construction has two kinds of seam connecting methods, and one is that wet seam is assembled, and another kind is that cementing seam is assembled.Wherein, cementing seam erection method is the sections that the utilizes casting complete end mould as next sections, and two segment is engaged completely at seam crossing.The assembled phase specific humidity of cementing seam seam is assembled constructs faster without carrying out Cast-in-Situ Segment reinforcing bar binding, prestress pipe installation and concrete curing, and construction quality more easily ensures.While adopting the construction method of bonded process Precast Concrete Segmental Bridges, between piece part, there is connecting sewing face.For each point of module component formed to entirety, must butt joint part deal with, in making each part position accurately fixing, seam portion also should be able to Transfer of Shear, reaches malformation continuous.At present, conventional prefabrication of beam section assembling linkage mostly is rigidity shear connector, it is the splicing joint face place of adjacent two joint prefabricated subsections, trapezoidal or dentation shear connector is set during by prefabricated units, the slotting position of keyway is staggered, make the splicing joint faces of adjacent two joint case beam prefabricated sections form a protruding recessed interlock configuration, bear structure shearing.But easily cause because shear connector size is less the leakiness of vibrating, in the time of the demoulding, occur arrisdefect disrepair phenomenon, and end mould processed complex, disturbing greatly with prestressed pore passage, formwork cost is high, and construction accuracy is difficult to ensure.
Summary of the invention
The object of this invention is to provide a kind of precast segment spliced girder body structure that steel sleeve elasticity shear tenon is set, effective Transfer of Shear in the cementing seam splicing structure of prefabricated subsection.
The technical solution adopted in the present invention is:
The precast segment spliced girder body structure of steel sleeve elasticity shear tenon is set, includes the prefabrication of beam sections of case beam type, it is characterized in that:
The cavity edge of prefabrication of beam sections both ends of the surface is provided with the diaphragm of all shapes of ring, has been evenly arranged reserving hole on diaphragm, is embedded with outer steel pipe in reserving hole;
Adjacent two joint prefabrication of beam sections splice mutually, in the corresponding outer steel pipe in position, penetrate inner sleeve steel pipe.
Described inner sleeve steel pipe is provided with axial inner sleeve joint-cutting.
Described inner sleeve steel pipe one end is taper.
The present invention has the following advantages:
The invention provides a kind of construction simple, template utilization rate is high, Liang Tigang bundle disturbs little, stressed uniform prefabrication of beam section assembling syndeton, compared with normally used rigidity shear connector, avoid easily damaged and uncompacted defect of vibrating of key piece and keyway, beam body end mould simplified processing, utilization rate is high, because shear tenon is arranged in diaphragm, utilize diaphragm width, avoid the interference of shear tenon layout with beam prestressing with bond duct, facilitate presstressed reinforcing steel to arrange, the layout of shear tenon is also more even because not having interference to arrange simultaneously, stress performance is good.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
A kind of precast segment spliced girder body structure that steel sleeve elasticity shear tenon is set the present invention relates to, include the prefabrication of beam sections 4 of case beam type, the cavity edge of prefabrication of beam sections 4 both ends of the surface is provided with the diaphragm 8 of all shapes of ring, on diaphragm 8, be evenly arranged reserving hole, in reserving hole, be embedded with outer steel pipe 3.Adjacent two joint prefabrication of beam sections 8 splicings mutually, penetrate inner sleeve steel pipe 2 in the corresponding outer steel pipe 3 in position.In beam section seam 6, fill glue and connect adjacent two joint prefabrication of beam sections 8.
Inner sleeve steel pipe 2 and outer steel pipe 3 have formed steel sleeve elasticity shear tenon 1, and the joint connecting equipment while being prefabrication of beam assembling construction, for transmitting the shearing of assembled section of seam crossing and in assembled location time in place of work progress structure.Inner sleeve steel pipe 2 is provided with axial inner sleeve joint-cutting 7, makes the steel pipe can elastic deformation; Inner sleeve steel pipe 2 one end are taper, are convenient to penetrate the interior formation Tenon of outer steel pipe 3.Beam section is welded inner sleeve joint-cutting 7 after having spliced again, reduces the elastic deformation of operation stage.
It is cited that content of the present invention is not limited to embodiment, and the conversion of any equivalence that those of ordinary skill in the art take technical solution of the present invention by reading manual of the present invention, is claim of the present invention and contains.
