Abstract
The utility model discloses a rubber dam bag anchoring device which is provided with an embedded anchoring bolt, a steel base plate, a bottom gasket, a steel pressing plate and a hold-down nut. An inner pressing strip is arranged under the bottom gasket. An outer pressing strip is arranged under the steel pressing plate. A rubber dam bag is placed between the bottom gasket and the outer pressing strip, and then the hold-down nut is tightly screwed. A concave curved line is formed at the anchored position between the rubber dam bag and the bottom gasket. When the rubber dam bag is filled with water or air and is in a working state, acting force on rubber cloth of a bag body is uniformly distributed and the rubber dam bag is not prone to be damaged. Meanwhile, the contact area between the pressing strips and the rubber dam bag is small. Consequently, the rubber dam bag can be squeezed more tightly, can firmly and reliably bear pressure of water inside and outside and can also meet requirements for water sealing or air sealing.
Description
Technical field
The utility model belongs to the water conservancy project building technical field, is specifically related to a kind of rubber dam bag anchor device.
Background technology
Rubber dam project is a kind of novel water retaining structure, with adopting the synthetic adhesive plaster of rubber and fiber as the dam bag, is anchored on dam foundation plinth and the headwall, forms the flexible water retaining structure of sealing.Because of its novel structure, social benefit obviously, advantage such as convenient management, numerous areas such as be widely used in flood control, irrigation, town and country water supply, hydroelectric generation, beautify the environment.Rubber dam bag bears the external and internal pressure of water, is the main body of engineering dash operation, to the anchoring of rubber dam bag, good sealing property should be arranged, and is solid and reliable again.So just can make rubber dam play the dash effect, guarantee normal operation.
In the prior art, to the anchoring of rubber dam bag, employing be the bolt clip plate anchoring process.Specifically be by pre-embedded bolt, punched steel plate and dam bag are pressed abd fixed on the dam base plate.This method, dam bag anchoring place stress distribution inequality, easy damaged dam bag; For the anchoring of high dam (surpass 5 meters height of dam) dam bag, because the dam bagging is thicker, bolt is not easy to compress, and sealing effectiveness is poor, and when being subjected to strong water impact, the dam bag is prone to serious seepage phenomenon.
Summary of the invention
The purpose of this utility model is, at the deficiencies in the prior art, provides a kind of bolt to compress easily, and stress distribution is even, and good sealing effect, dam bag be the rubber dam bag anchor device of easy damaged not.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of rubber dam bag anchor device, have pre-buried anchor bolt, billet, bottom spacer, keeper plate of steel and clamping nut, it is characterized in that: below bottom spacer, be provided with inside casing, below keeper plate of steel, be provided with outside casing, when rubber dam bag is put between bottom spacer and the outside casing, when screwing clamping nut, make rubber dam bag and bottom spacer form concavity shaped form down in anchoring place.
Described inside casing, outside casing are respectively the frame type structure that periphery is communicated with.
The beneficial effects of the utility model: owing to below bottom spacer, be provided with inside casing, below keeper plate of steel, be provided with outside casing, therefore, rubber dam bag put between bottom spacer and the outside casing, when screwing clamping nut, rubber dam bag and bottom spacer form concavity shaped form down in anchoring place.After rubber dam bag was full of water (gas), enters duty, the active force on the bag rubberized fabric evenly distributed, not easy damaged dam bag; Simultaneously, press strip and rubber dam bag contact area are big, can guarantee rubber dam bag extruding tightlyer, make it can bear the pressure of inside and outside water solid and reliablely, can satisfy water (gas) seal request again.The utility model reduces the rubber dam bag seepage for the loosening and wearing and tearing of avoiding rubber dam bag, reduces maintenance and overhead cost, guarantees that the normal operation of engineering has remarkable economic efficiency and social benefit.
Description of drawings
Fig. 1 is a rubber dam bag anchor device structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, a kind of rubber dam bag anchor device, have the anchor bolt 1, billet 2, bottom spacer 3, keeper plate of steel 4 and the clamping nut 5 that are embedded on the dam foundation 8, below bottom spacer, be provided with inside casing 6, below keeper plate of steel, be provided with outside casing 7, when rubber dam bag is put between bottom spacer 3 and the outside casing 7, when screwing clamping nut 5, rubber dam bag 9 and bottom spacer 3 form concavity shaped form down in anchoring place.
Inside casing, outside casing can be respectively the frame type structure that periphery is communicated with, and it is more convenient to construct, better effects if.
Claims (2)
1. rubber dam bag anchor device, have pre-buried anchor bolt, billet, bottom spacer, keeper plate of steel and clamping nut, it is characterized in that: below bottom spacer, be provided with inside casing, below keeper plate of steel, be provided with outside casing, when rubber dam bag is put between bottom spacer and the outside casing, when screwing clamping nut, make rubber dam bag and bottom spacer form concavity shaped form down in anchoring place.
2. a kind of rubber dam bag anchor device according to claim 1 is characterized in that: described inside casing, outside casing are respectively the frame type structure that periphery is communicated with.
