Description
Technical field
The utility model relates to a kind of hanging-connecting crab-bolt counterforce device, belongs to crab-bolt counterforce device technical field.
Background technology
The quiet stake of anchor pole is a kind of emerging foundation construction technology, is usually used in the engineerings such as the underpin of existing building, rectifying of leaned building, foundation underpinning, building jacking, the transformation of existing building Space Expanding.The features such as anchor pole quiet pile foundation construction equipment has light and flexible, easy to operate, noise is low, it is little to pollute, low energy consumption.Substantially civilized construction requirement is met.But existing counterforce device can't meet the demand of this construction technology development completely.Construct with electric hammer or pneumatic pick as stake holes perforate, anchor pole and basis connect be connect firmly with the method for implantation gluedd joint together with, counterforce device is integral frame Combination Welding structure.Owing to constructing with electric hammer or pneumatic pick, there is the problem that noise is large, energy consumption is high, basic destruction is also larger, do not reach civilization, environmental protection construction requirement.
Summary of the invention
The purpose of this utility model is to solve above-mentioned prior art Problems existing, namely owing to constructing with electric hammer or pneumatic pick, there is the problem that noise is large, energy consumption is high, basic destruction is also larger, does not reach civilization, environmental protection construction requirement.And then a kind of hanging-connecting crab-bolt counterforce device is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hanging-connecting crab-bolt counterforce device, comprise: hanging-connecting crab-bolt, threaded connecting sleeve, counter-force pull bar, setscrew nut, reaction plate, hold-down nut, hydraulic jack, oil pipe and hydraulic pump, by hanging-connecting crab-bolt, threaded connecting sleeve and counter-force pull bar composition counter-force draw piece, the lower end of described counter-force pull bar is threaded by threaded connecting sleeve with between the upper end of hanging-connecting crab-bolt, the upper end of counter-force pull bar is connected with reaction plate, setscrew nut is arranged on the counter-force pull bar of reaction plate bottom, hold-down nut is arranged on the counter-force pull bar on reaction plate top, the upper end of hydraulic jack is connected with reaction plate, oil pipe is connected with between hydraulic jack and hydraulic pump.
In existing construction foundation basic reinforcing engineering technology, often use anchor rod static pressure pile construction method.Anchor jacked pile is that anchor pole technique and static pressure pile process two kinds of technology combine and a kind of brand-new construction method produced.The anchor rod static pressure pile construction method used in present existing construction foundation basic reinforcing engineering with tendon-planted craft, anchor pole is fixed in existing building basis.Bar planting method is subject to multiple construction and natural conditions restriction in work progress, and fixing reliability is affected.The anti-frame input that anchor rod static pressure pile driving construction is used is in addition many, weight large, it is high to come and go landed cost, is not suitable for a large amount of uses when existing building promotes.Hanging-connecting crab-bolt counterforce device of the present utility model, volume is little, lightweight, installation is fast.Hanging-connecting crab-bolt counterforce device have employed hanging-connecting crab-bolt makes anchoring quality safe and reliable.Be applicable to the underpin of various existing building, correction, jacking, the inverse construction done.
