Abstract
The utility model provides an anticorrosive device for prestress anchorage devices of bridge backstay cables and the like, in particular to a steel strand anchorage device preservative melting device. The steel strand anchorage device preservative melting device comprises an anchorage device assembly which is composed of a sealed chamber and an anchor plate, wherein the sealed chamber is connected with the anchor plate. The anchor plate is provided with a perfusion through hole leading to the inside of the sealed chamber. The steel strand anchorage device preservative melting device further comprises a melting bar which is installed on the anchorage device assembly and is good in heat-conducting property, wherein one end of the melting bar is provided with a back-out pull ring, and the other end of the melting bar is inserted into the sealed chamber through the perfusion through hole. The sealed chamber is perfused with oil pasty anticorrosive material. The steel strand anchorage device preservative melting device is simple in structure and low in manufacturing cost. Moreover, when performance of the anticorrosive material changes and cables of steel strands need replacing, the steel strand anchorage device preservative melting device can assist the anticorrosive material to be replaced easily and conveniently, and reliability of corrosion prevention of anchorage devices is guaranteed.
Description
Technical field
The utility model belongs to the road and bridge technical field.The anti-corrosive apparatus of prestressed anchor such as bridge cable particularly.
Background technology
At present, bridge is with pouring into anti-corrosion material (grease, paraffin etc.) in the prestress wire dragline anchorage usually, to protect exposed steel strand surface.Because filling cavity is a sealing drum that is difficult to open, its inner anti-corrosion material of being annotated is a mobile at normal temperatures relatively poor ointment (fat).When said anti-corrosion material performance changes or steel strand need change rope the time, be difficult to the anti-corrosion material in the sealing drum is extracted with the new anti-corrosion material of annotating.To sum up, in the use of bridge Cheng Qiaohou, because the anti-corrosion material in the ground tackle can not get in time substituting, make bridge inspection and maintenance difficult, traffic safety can not get effective assurance.
Summary of the invention
The purpose of the utility model provides a kind of steel strand anchorage anticorrisive agent fusing device, can monitor the anticorrosion situation in the ground tackle, the auxiliary anti-corrosion material of changing easily and effectively, to ensure the safety of bridge.
For realizing that the technical scheme that the utility model purpose adopts is such, a kind of steel strand anchorage anticorrisive agent fusing device comprises the ground tackle assembly that is made up of sealing drum that links together and anchor slab, and said anchor slab has the perfusion through hole that leads to sealing drum inside.Also comprise be installed on the said ground tackle assembly, fusion that heat conductivility is good rod, an end of said fusion rod is equipped with and screws out draw ring, the other end is inserted in the sealing drum through said perfusion through hole.Be perfused with the anti-corrosion material of ointment shape in the said sealing drum.At Cheng Qiaohou; Because of the anti-corrosion material performance changes or steel strand need change rope; When need extracting mobile relatively poor anti-corrosion material out, can the anti-corrosion material in the ground tackle fully be fused, extract original anti-corrosion material easily out through heating fusion rod; Again pour into new anti-corrosion material then, let ground tackle inside effectively protected.
The utility model is because said structure, and its advantage is: apparatus structure is simple, and low cost of manufacture is widely used in the prestressed anchor in bridge field.When the anti-corrosion material performance changes or steel strand need change rope the time, the auxiliary anti-corrosion material of changing is guaranteed the anticorrosion reliability of ground tackle, has effectively ensured the safety of bridge.
Description of drawings
The device of the utility model can further specify through the non-limiting embodiment that accompanying drawing provides.
Fig. 1 is the sectional view of the fusion rod of the utility model;
Fig. 2 is the use sketch map of the utility model;
Fig. 3 is a ground tackle sketch map in the prior art.
Among the figure: 1-screws out draw ring, and 2-sealing thread, 3-fuse rod, the 4-anchor slab, and the 5-sealing drum, 6-pours into through hole, 7-electro-heat equipment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further, only limits to following embodiment but should not be construed the above-mentioned subject area of the utility model.Under the situation that does not break away from the above-mentioned technological thought of the utility model, according to ordinary skill knowledge and customary means, make various replacements and change, all should be included in the utility model scope.
Referring to accompanying drawing: a kind of steel strand anchorage anticorrisive agent fusing device, comprise the ground tackle assembly that constitutes by sealing drum that links together 5 and anchor slab 4, said anchor slab 4 has and leads to the inner perfusion through hole 6 of sealing drum 5.Also comprise be installed on the said ground tackle assembly, fusion that heat conductivility is good rod 3, an end of said fusion rod 3 is equipped with and screws out draw ring 1, the other end is inserted in the sealing drum 5 through said perfusion through hole 6.Be perfused with the anti-corrosion material of ointment shape in the said sealing drum, fusion rod 3 immerses in the anti-corrosion material when inserting.When need changing anti-corrosion material, only need heating fusion rod 3, tube to be sealed 5 inner old anti-corrosion material fully melt after, screw out heating fusion rod 3, can extract out easily.At last, through the perfusion through hole 6 new anti-corrosion material of in sealing drum 5, annotating, can accomplish maintenance work.
Among the embodiment, have sealing thread 2 on the barred body of said fusion rod 3, said perfusion through hole 6 has the internal thread that matches with said sealing thread 2.After the perfusion of the anti-corrosion material in the ground tackle finishes, can fusion rod 3 be screwed in perfusion through hole 6, can anti-corrosion material be sealed in interior secluding air.Further, in the middle of bridge uses, can also screw out fusion rod 3, through observing the variation with the monitoring anti-corrosion material of the anti-corrosion material taken out of on the fusion rod 3, whether decision is changed anti-corrosion material.
Because anti-corrosion material is some mobile relatively poor greases normally, particularly after it is rotten, more be difficult to extract out, give and safeguard or construction brings constant.Further, said fusion rod 3 has electro-heat equipment 7.Electric heater unit in normally excellent.When needs are changed anti-corrosion material, only need energising make 3 heatings of fusion rod, make anti-corrosion material melt.After treating that anti-corrosion material fully melts, fusion rod 3 is screwed out, can extract original anti-corrosion material, the new anti-corrosion material of perfusion easily out through rotating back-out draw ring 1.
