Abstract
The utility model relates to a combined pre-built-in bolt casing tube used in a non-broken piece orbit, which belongs to the technical field of railway construction. The utility model is provided with a nylon bolt casing tube, wherein a metal casing tube is sheathed outside the nylon bolt casing tube, screw threads matched with each other are arranged on the inner wall of the metal casing tube and the outer wall of the bolt casing tube, and the metal casing tube is sheathed on the nylon bolt casing tube by the screw threads. The utility model has the advantages that the nylon casing tube can be conveniently replaced, and concrete sleeper and road bed are not damaged; the utility model can improve the stress condition of the nylon casing tube, and the damage, such as cracking, breakage, etc., is reduced. The utility model can be used for replacing the existing nylon bolt casing tube.
Description
Technical field
The utility model relates to a kind of bolt sleeve that is cast in the ballastless track in the railway construction technology neighborhood.
Background technology
In ballastless track construction, bolt sleeve must be cast in the concrete, again anchor bolt is installed in the bolt sleeve anchoring after solidifying with steel rail laying.Existing bolt sleeve is the nylon bolt sleeve pipe, and after cast was advanced in the concrete sleeper, because of it in use can wear out and wear and tear, application life can not be synchronous with concrete sleeper, and in case after being embedded in the concrete, change very difficult.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes existing nylon sleeve, and a kind of combined type pre-embedded bolt sleeve pipe that can be convenient for changing nylon sleeve is provided.
Realize the combined type pre-embedded bolt sleeve pipe of the utility model purpose, has a nylon bolt sleeve pipe, be socketed with a metal sleeve in the outside of described nylon bolt sleeve pipe, the outer wall of the inwall of metal sleeve and nylon bolt sleeve pipe is provided with the screw thread that cooperatively interacts, and described metal sleeve is connected on the nylon bolt sleeve pipe by thread bush.After this combined type pre-embedded bolt sleeve pipe is cast in the concrete sleeper, metal sleeve and concrete become one and can with the same life-span of concrete.Nylon sleeve can screw out from metal sleeve after damaging, and screws in new nylon sleeve in addition and realizes being convenient for changing.
For preventing when this combined type pre-embedded bolt sleeve pipe being poured into a mould into concrete sleeper, there is not the concrete grout of sclerosis to enter into sleeve pipe, cause the curtailment that enters when anchor bolt is afterwards installed, can be provided with a capping in the bottom of described metal sleeve.
The utility model has the advantages that: can be convenient for changing nylon sleeve, not damage concrete sleeper and railway roadbed; Metal sleeve also can improve the breaking resistance in nylon sleeve and concrete screw-bolt hole; Behind the nylon sleeve added metal sleeve pipe, can improve the stress condition of nylon sleeve, reduce infringements such as cracking, breakage.Capping is set, can stops the concrete of ot-yet-hardened in the casting process to enter bolt sleeve to guarantee the length that enters of anchor bolt effectively from sleeve bottom.Alternative existing nylon bolt sleeve pipe uses.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Referring to Fig. 1, this combined type pre-embedded bolt sleeve pipe, has a nylon bolt sleeve pipe 1, be socketed with a metal sleeve 2 in the outside of described nylon bolt sleeve pipe 1, the outer wall of the inwall of metal sleeve and nylon bolt sleeve pipe is provided with the screw thread 3,4 that cooperatively interacts, and described metal sleeve 2 is connected on the nylon bolt sleeve pipe 1 by thread bush.The nylon bolt sleeve pipe can be continued to use existing product, and the metal sleeve available thickness is that the stainless steel of 2mm is made into the helical corrugation tubulose that matches with existing nylon bolt sleeve pipe.This on its outer wall ripply metal sleeve have bigger ability of solidifying than the smooth metal sleeve of outer wall with the coagulation soil phase.Also the pitch of the screw thread on the nylon bolt sleeve outer wall can be designed to its internal thread inequality.
The concrete of ot-yet-hardened enters bolt sleeve from sleeve bottom in casting process in order to stop, and can be provided with a capping 5 in the bottom of described metal sleeve.Capping 5 is a nylon cock lid with screw thread in the present embodiment, and the bottom of precession metal sleeve is with its shutoff.In this case, the length of metal sleeve should be longer than nylon sleeve.Capping also can be a plate, is welded on the bottom of metal sleeve.
Claims (2)
1, a kind of combined type pre-embedded bolt sleeve pipe that is used for ballastless track, has a nylon bolt sleeve pipe, it is characterized in that being socketed with a metal sleeve in the outside of described nylon bolt sleeve pipe, the outer wall of the inwall of metal sleeve and nylon bolt sleeve pipe is provided with the screw thread that cooperatively interacts, and described metal sleeve is connected on the nylon bolt sleeve pipe by thread bush.
2, combined type pre-embedded bolt sleeve pipe as claimed in claim 1 is characterized in that being provided with in the bottom of described metal sleeve a capping.
