Abstract
The utility model belongs to protection of an anchor cable structure in building and bridge construction, and particularly relates to a non-adhesion anchor cable protection device which comprises a non-adhesion anchor cable body, wherein the anchor position is provided with a protective cap. The non-adhesion anchor cable protection device is characterized in that an oil spill pipe of a hollow tubular structure is arranged in the protective cap, the opening in one end of the oil spill pipe is an oil filling hole, and an oil outlet hole in the other end of the oil spill pipe is formed in the inner side of the protective cap. The non-adhesion anchor cable protection device is characterized in that even in high-temperature weather or on a slope position, grease flows into the oil spill pipe along with rising of the temperature, and due to the fact that the grease in the protective cap is limited, the amount of the overflowing grease is much reduced compared with the prior art due to the containing function of the oil spill pipe. Therefore, people do not need to fill oil into the oil filling hole frequently. Particularly in the field, the temperature difference of day and night is large, and after the temperature is lowered, the grease may flow back to the protective cap. The protection device is more convenient to maintain and use after being improved.
Description
Technical field
The utility model belongs to the protection of building, bridge construction anchor cable structure, specifically, is exactly the protector without the cementability anchor cable.
Background technology
Many anchoring engineerings adopt the method for concrete or cement mortar covering to be protected without the outer ground tackle of bonding anchor cable, process two problems are arranged like this, the one, when needs are adjusted anchor cable prestressing force, must be the concrete cover fragmentation, and thoroughly know the cement paste in the ground tackle outside, carrying out concrete sealing, trivial operations after adjustment; The 2nd, the protection of ground tackle is not too reliable.Can form passivating film on the ground tackle surface with the concrete of portland cement mixing, prevent the corrosion of iron and steel, but ground tackle and covering layer thereof be in atmosphere, than the anchor cable circumstance complication in buried stratum, the CO in atmosphere
2, acid rain and other hazardous substancess can make the concrete carbonization, reduces its basicity, likely makes ground tackle lose established passivating film and corrosion.Different without the bonding anchor cable of bonding anchor cable and total length, the stressed locality characteristics of the bonding anchor cable of total length determined the ground tackle corrosion even lost efficacy little to the reinforcement effect of anchor cable, but just mean the whole inefficacy of anchor cable without the inefficacy of bonding Anchor Cable Anchorage.Existing hard hat leaks in order to prevent grease, in the end of hard hat, is provided with oil filler point, the grease overflowed during in order to supplementary high temperature.But, just more frequent in the maintenance of hot weather.
Summary of the invention
The utility model is in order to solve existing anchor cable device in protection, grease needs the problem of regularly filling, a kind of protector without bonding anchor cable is provided, the technical scheme of taking is: comprise without bonding anchor cable body, be provided with hard hat in its ground tackle position, it is characterized in that: be provided with the oil spill pipe of the tubular structure of hollow in hard hat, an end opening is oil filler point, and other end oil outlet is in the hard hat inboard.
Described hard hat is connected with ground tackle by backing plate.
Be filled with grease in described hard hat.
The utility model has the advantage of: even in hot weather or side slope position; if along with the rising of temperature, grease can flow into oil spill pipe, because the grease in protective cap is limited; therefore due to the effect of holding of oil spill pipe, the oil quantity overflowed is compared than before and is reduced a lot.Therefore, can be frequently through the oil filler point oiling.Especially area, field, the temperature difference is larger sooner or later, and after temperature reduces, grease can be back in protective cap.Improved protective device is more convenient for safeguarding and using.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1-hard hat, 2-oil spill pipe, 3-oil filler point, 4-oil outlet, 5-without bonding anchor cable body.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of protector without bonding anchor cable comprises and is provided with hard hat 1 without bonding anchor cable body 5 in its ground tackle position that oil spill pipe 2, one end openings that are provided with the tubular structure of hollow in hard hat are oil filler point 3, and other end oil outlet 4 is in the hard hat inboard.Hard hat is connected with ground tackle by backing plate.Be filled with grease in hard hat.
