Abstract
The utility model discloses an umbelliform anti anchor of pulling out, including biography power noose (1) and lower part sleeve (7), be equipped with down chassis (6) on lower part sleeve (7), be equipped with chassis (3) above lower part sleeve (7), swing joint has balancing pole (4) on last chassis (3), swing joint has from expander bar (5) on chassis (6) down, and balancing pole (4) and from expander bar (5) swing joint, the one end and the lower part sleeve (7) of biography power noose (1) are connected, the other end of biography power noose (1) and pass in follow last chassis (3). Under the action of the pulling force, the umbrella wings, namely the balancing rods and the self-expanding rods, are opened to form a soil column (soil pile) with thick bottom area; utilize the weight of the soil body itself and the shear strength of soil and soil itself to provide the required resistance to plucking of basis, make the utility model discloses a atress performance improves, has improved the degree of safety of building.
Description
Technical field
The utility model relates to a kind of building anti-float anchor rod, relates in particular to a kind of umbrella resistance to plucking anchor.
Background technology
Along with the development and utilization energetically of the underground space, we run into the problem of pulling out load in the increasing opposing in the engineering construction.The come-up situation that needs to solve structure gets more and more, as the underground square in high water level area, underground garage and water treatment building etc.At present, the anti-floating of building design mainly contains two kinds of anti-floating stake and anti-float anchor rods.The anti-floating stake usually and sole plate fixed fully, it is uplift pile when underground water level is higher, when underground water level was low, it had become again and has been subjected to piling, plays the effect of minimizing building settlement; And anti-float anchor rod only is anchored on the sole plate by steel strand, and between anchor pole and sole plate bed course is set, only when groundwater table is higher, anti-float anchor rod plays a role, and lower in groundwater table, when building had sedimentation trend, anchor pole is almost not effect then.
For uplift pile, its uplift resistance that can provide is mainly from two aspects: the vertical gravity that the concrete of stake side and the frictional resistance of soil provide the quality of downward pulling force and pile body itself to provide to uplift pile, the former adopts for the concrete based on the pressurized performance, raise weak point a little and keep away length, lose more than gain; The latter adopts quality of concrete to replace the quality of soil itself, and it also is not a lot of increasing, and wastes bigger.For the resistance to plucking anchor pole, its uplift resistance that can provide mainly from the concrete of anchoring body and the frictional resistance of soil, generally less, if will obtain than large pulling resistance, waste also bigger by the rock-bolt length that then need extend.
Summary of the invention
The utility model provides a kind of simple in structure, umbrella resistance to plucking anchor that stress performance is good.
The utility model adopts following technical scheme:
A kind of umbrella resistance to plucking anchor, comprise power transmission strand cable and lower sleeve portion, on lower sleeve portion, be provided with low bottom-disc, above lower sleeve portion, be provided with top bottom-disc, on top bottom-disc, be connected with balancing pole, on low bottom-disc, be connected with from spreader bar, and balancing pole and flexibly connect from spreader bar, one end of power transmission strand cable is connected with lower sleeve portion, the other end of power transmission strand cable and passing from top bottom-disc.
Compared with prior art, the utlity model has following advantage:
1, the utility model is simple in structure, stress performance good.The utility model is under tension, and the umbrella wing is balancing pole and will opens from spreader bar, forms the very thick earth pillar of floor space (soil stake); Utilize the weight of the soil body itself and the shear strength of soil and soil itself to provide the basis required uplift resistance, make stress performance of the present utility model improve, improved the degree of safety of building, this and in the past only depend on anchoring body or pile body itself provide the resistance to plucking technology of uplift resistance more reasonable.
2, the utility model is easy to use and can reduce cost.With regard to the utility model itself, its weight by the soil body self provides uplift resistance, can reduce the difficulty of pile, and is convenient for users to use, and reduce concrete consumption, thereby reduced the cost and the cost of engineering.
