Abstract
The utility model belongs to the technical field of the tubular pile and specifically relates to joint design of iron road bridge roof beam major diameter PHC tubular pile, its characterized in that: the joint design includes that connecting piece and pyrocondensation are pullover, the connecting piece with it is fixed to constitute bolted connection between the end plate of two root canal stakes respectively, the pullover cladding of pyrocondensation is in the periphery of connecting piece. The utility model has the advantages that: construction speed is fast, welding quality is high, joint strength is high, stability is strong, the durability is strong, simple structure, reasonable is suitable for the popularization.
Description
Technical field
This utility model relates to pile tube field, the especially joint design of railroad bridge PHC tube pile of major diameter.
Background technology
The joint of pile tube processes to be divided into being welded to connect and is connected with bolt, and wherein bolt connects the pipe pile foundation for being chronically at subsoil water, and durability is poor, and joint certainly will become the weak link of pile foundation.And be welded to connect and generally use common welding rod welding, but because of cooling duration after welding, affect speed of application or welding quality.In order to improve construction effect, it is ensured that can pile sinking, existing many employing carbon-dioxide arc welding method welding, but the problem that there is also length weld interval continuously in time after welding.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art, provide the joint design of railroad bridge PHC tube pile of major diameter, two root canal piles are connected by connector bolt, realize the quick connection between two root canal piles, simultaneously pullover in the cladding pyrocondensation of connector periphery, improve the durability of connector.
This utility model purpose realizes being completed by techniques below scheme:
A kind of joint design of railroad bridge PHC tube pile of major diameter, realize the connection between two root canal piles, it is characterized in that: described joint design includes that connector is pullover with pyrocondensation, respectively constitute bolt between described connector and the end plate of described two root canal piles and be connected fixing, the pullover periphery being coated on described connector of described pyrocondensation.
Respectively constitute bolt between described connector and the end plate of described two root canal piles and be connected fixing referring to, the end plate of described two root canal piles offers bolt hole respectively, described connector offers the adaptive installing hole that coincide with the described bolt hole on described two root canal pile end faces respectively, is bolted between described bolt hole with described installing hole between the fixing end plate making described two root canal piles to be connected by described connector and fixes.
The utility model has the advantages that: speed of application is fast, welding quality is high；Bonding strength is high, stability is strong；Durability is strong；Simple and reasonable for structure, be suitable to promote.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
This utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, in order to the understanding of technical staff of the same trade:
As it is shown in figure 1, labelling 1-7 is expressed as in figure: pile tube 1, pile tube 2, end plate 3, end plate 4, connector 5, bolt 6, pyrocondensation pullover 7.
Embodiment: as it is shown in figure 1, the joint design of railroad bridge PHC tube pile of major diameter is used for connecting pile tube 1 and pile tube 2 in the present embodiment.The bottom of pile tube 1 is end plate 3, and the top of pile tube 2 is end plate 4.
Bolt hole (not shown) is offered respectively on the surface of end plate 3 and end plate 4, connector 5 is sleeved on end plate 3 and the periphery of end plate 4, offers and respectively constitute, with the bolt hole on end plate 3 and end plate 4, adaptive installing hole (not shown) of coincideing on connector 5.Bolt 6 is tightened among bolt hole and installing hole so that connector 5 constitutes connecting bolt respectively and is connected fixing with end plate 3 and end plate 4, and so, end plate 3 and end plate 4 will pass through connector 5 and connect fixing, and the connection being also achieved that between pile tube 1 and pile tube 2 is fixed.
As it is shown in figure 1, be coated with pyrocondensation pullover 7 in the periphery of connector 5, pyrocondensation pullover 7 is for closing the junction between connector 5 and pile tube 1 and pile tube 2, thus plays a protective role, and improves connector 5 and the durability of junction.
The present embodiment is in the specific implementation: when preparing to connect pile tube 1 and pile tube 2, can be in the sheathed pyrocondensation of stake end pullover 7 of pile tube 2；After treating that the connection being completed between pile tube 1 and pile tube 2 by the cooperation of connector 5 and bolt 6 is fixed；Adjust pullover for pyrocondensation 7 to suitable height, after i.e. meeting the requirement of its junction being coated with between connector 5 and pile tube 1 and pile tube 2, pullover to pyrocondensation 7 carry out heat treated, make pullover 7 heat shrinkable of pyrocondensation, it is made to be adjacent to mutually with the end sheet surface of pile tube 1 and pile tube 2, so that pyrocondensation is pullover, junction between connector 5 and pile tube 1 and pile tube 2 is closed, improve durability.
Although design and the embodiment of this utility model purpose is elaborated by above example referring to the drawings, but those of ordinary skill in the art will be consequently realised that, under the precondition limiting scope without departing from claim, still this utility model can be made various modifications and variations, as: the version of connector 5, bolt hole, the quantity etc. of installing hole, therefore repeat the most one by one at this.
