Abstract
The utility model discloses a replaceable contact network pillar base which comprises anchor bolts pre-buried in concrete, wherein bolts are in threaded connection onto the anchor bolts. The replaceable contact network pillar base is simple in structure, reasonable in design, low-carbon and environment-friendly and can be used repeatedly, and follow-up maintenance and repairing cost and difficulty are reduced effectively.
Description
Technical field
The utility model belongs to railway road and bridge construction technical field, particularly relates to a kind of mast foundation for overhead contact wire system.
Background technology
Tradition mast foundation for overhead contact wire system adopts cast-in fixing bolt form, and crab-bolt is vertical state, and fixing steel plate is established for locating pre-embedded bolt in each basic top.As time goes on, because the reasons such as environmental attack, railway operation make the corrosion of crab-bolt exposed parts, destruction, reduce bearing capacity and can not normally use.Although it is intact to be embedded in the crab-bolt of inside concrete, really cancelling in whole crab-bolt basis, cannot re-use, and the difficulty that causes later maintenance, repairing greatly and the wasting of resources.
Utility model content
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art part exactly, and a kind of replaceable mast foundation for overhead contact wire system is provided, once solve prior art crab-bolt exposed parts, by corrosion, after destroying, with regard to integral body, scrap, and the problem that cannot use.
The purpose of this utility model realizes by following technical proposals:
A replaceable mast foundation for overhead contact wire system, comprises the crab-bolt being embedded in advance in concrete, threaded connection bolt in described crab-bolt.
Further, described crab-bolt outer wall is vertically provided with a plurality of grooves, thereby has increased and concrete contact area, and shear resistance strengthens.
Further, described crab-bolt bottom sets firmly resistance to plucking plate, has strengthened the uplift resistance of crab-bolt.
Further, there is zinc coat on described crab-bolt surface.
The beneficial effects of the utility model are: simple in structure, reasonable in design, reusable, low-carbon environment-friendly, effectively reduces later maintenance, repair cost and difficulty.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of crab-bolt in Fig. 1;
Fig. 3 is the structural representation of bolt in Fig. 1;
Fig. 4 is the structural representation of fixing steel plate in Fig. 1.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figures 1 to 4, a kind of replaceable mast foundation for overhead contact wire system, comprises the crab-bolt 1 being embedded in advance in concrete, threaded connection bolt 2 in described crab-bolt 1.
Described crab-bolt 1 outer wall is vertically provided with a plurality of annular grooves 3, thereby has increased and concrete contact area, and shear resistance strengthens.Described crab-bolt 1 bottom sets firmly resistance to plucking plate 4, and this resistance to plucking plate 4 can be square plate.There is zinc coat on described crab-bolt 1 surface.
When constructing, this mast foundation for overhead contact wire system top arranges fixing steel plate 5 for positioning bolt 2, offers the hole 6 matching with pre-buried crab-bolt 1 position on fixing steel plate 5, and bolt 2 is connected with crab-bolt 1 through fixing steel plate 5.Because crab-bolt 1 is to be embedded in advance in concrete, therefore can not suffer erosion and destroy, can reuse low-carbon environment-friendly.And the bolt 2 exposing and fixing steel plate 5 can be changed after by corrosion, destruction, very convenient.This mast foundation for overhead contact wire system can be used in various road and bridge line construction.
The utility model is different from position according to the circuit types using, and has different bearing capacities and title, as following eight kinds (they wherein, are name of product before bracket, bracket is interior is Chinese lexical or textual analysis):
Anchor-20 in the middle of 1.SX-TZJM-20(two-wire-T beam, 20 is bearing capacity, unit K N)
2.SX-TGJM-35(anchor-35, two-wire-T beam joint)
Anchor-15 in the middle of 3.SX-LZJM-15(two-wire-continuous beam)
Anchor-60,4.SX-LGJM-60(two-wire-continuous beam joint)
5.DX-TZJM-20(anchor-20 in the middle of single line-T beam)
6.DX-TGJM-35(anchor-35, single line-T beam joint)
Anchor-15 in the middle of 7.DX-LZJM-15(single line-continuous beam)
Anchor-60,8.DX-LGJM-60(single line-continuous beam joint).
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
