Description
Technical field
The present invention relates to connector of a kind of Prefabricated concrete-filled steel tube girder segment and attaching method thereof, belong to technical field of structural engineering.
Background technology
Along with construction scale of projects grows with each passing day, development structure prefabrication and assembly construction technology makes Prefabricated concrete-filled steel tube adapt to industrialization construction, and reduce situ wet workload, lifting construction efficiency and economy, also can promote that concrete filled steel tube is applied in bridge field as longeron.And Prefabricated concrete-filled steel tube joint is key position, it is comparatively large to bear axial compression and moment of flexure, will ensure that concrete axial is to close contact especially.Steel pipe is directly spliced after-pouring inner concrete by common prefabrication and assembly construction method cannot ensure that inner concrete is closely knit, and splice region power transmission is not direct, and globality is poor, or adopts complicated splice region structure, adds difficulty of construction, extends the duration, less economical.
Summary of the invention
The present invention is directed to deficiency of the prior art, propose connector of a kind of Prefabricated concrete-filled steel tube girder segment and attaching method thereof, made by steel tube concrete beam and all complete in the factory, the on-the-spot sections that only need complete connects.Simple structure of the present invention, rolled steel dosage is few, easy construction, and in-site installation speed is fast, and wet trade amount is little, little to surrounding environment influence, and stress performance is good simultaneously, the joint connection in site method between the reliable Prefabricated concrete-filled steel tube beam of power transmission.
Technical scheme of the present invention is as follows:
A connector for Prefabricated concrete-filled steel tube girder segment, is characterized in that, this connector is a taper lined steel pipe, and it is welded in one end of outer steel pipe.
The connector of Prefabricated concrete-filled steel tube girder segment of the present invention, the length that taper lined steel pipe stretches out outer steel pipe meets steel pipe build-in and passes curved requirement.
A method of attachment for Prefabricated concrete-filled steel tube girder segment, comprises the steps:
1) Prefabricated concrete-filled steel tube girder segment, one section of taper lined steel pipe is welded in one end of outer steel pipe, under the vertical state of steel pipe, build pipe inner concrete, ensure two ends concordant and outside steel pipe pre-set groove;
2) job site is spliced after two segment centering, connects outer steel pipe by butt weld, pours into high-strength mortar or high-strength grout afterwards from grouting mouth, will to be in the milk mouth and grout outlet sealing after grout outlet has mortar spilling.
4, method of attachment according to claim 3, is characterized in that, described taper lined steel pipe extension elongation meets steel pipe build-in and passes curved requirement.
The present invention has following beneficial effect relative to prior art:
(1) adopt the mode of prefabrication scene splicing, ensure that the closely knit of steel pipe inner concrete, good integrity, improve construction quality and anti-seismic performance; (2) the method for attachment simple structure of Prefabricated concrete-filled steel tube beam, easy construction, in-site installation speed is fast, concrete wet trade amount is little, little to surrounding environment influence, meets the requirement of green construction; (3) connecting structure stress performance is good, and power transmission is reliable; (4) adopt embedded sleeve pipe to make to there is space between sections, can do and necessarily regulate to correct structure misalignment of axe in scene.

Detailed description of the invention
Below in conjunction with accompanying drawing, structure of the present invention, processing and use procedure are further described.
The connector of a kind of Prefabricated concrete-filled steel tube girder segment of the present invention, this connector is a taper lined steel pipe 2, and it is welded in one end of outer steel pipe, as shown in Figure 3.The length that described taper lined steel pipe stretches out outer steel pipe meets steel pipe build-in and passes curved requirement.
Figure 1 shows that overall schematic of the present invention.
The method of attachment Specific construction step of Prefabricated concrete-filled steel tube girder segment of the present invention is as follows:
1) be prefabricated in the factory concrete filled steel tube girder segment (as shown in Figure 3), described sections comprises prefabricated reinforced concrete outer steel pipe 1, taper lined steel pipe 2, one section of taper lined steel pipe 2 is welded in one end of outer steel pipe 1, under the vertical state of steel pipe, build pipe inner concrete 3, ensure two ends concordant and outside steel pipe 1 pre-set groove.
2) (as shown in Figure 1) is spliced by after two segment centering in job site, connects outer steel pipe 1 by butt weld 7.Pour into high-strength mortar or high-strength grout 4 from grouting mouth 5 afterwards, will to be in the milk mouth and grout outlet sealing after grout outlet 6 has mortar to overflow.
Step 1) taper lined steel pipe extension elongation should meet steel pipe build-in and pass curved requirement, adopts taper lined steel pipe to make step 2) splicing can correct structure misalignment of axe; Step 2) mud jacking operation can ensure two segment concrete filled between closely knit contact.
Connector of Prefabricated concrete-filled steel tube girder segment of the present invention and attaching method thereof, is applicable to Loads of Long-span Bridges bridge deck, is conducive to the prefabrication and assembly construction mode of construction realizing encased structures.The present invention adopts the mode of prefabrication scene splicing, ensure that the closely knit of steel pipe inner concrete, good integrity, improves construction quality and anti-seismic performance; The method of attachment simple structure of Prefabricated concrete-filled steel tube beam, easy construction, in-site installation speed is fast, concrete wet trade amount is little, little to surrounding environment influence, meets the requirement of green construction; Connecting structure stress performance is good, and power transmission is reliable; Adopt embedded sleeve pipe to make to there is space between sections, can do and necessarily regulate to correct structure misalignment of axe in scene.
