Abstract
The utility model relates to a stretching device, in particular to a stretching device for a prestress applying bolt for a cable membrane structure. The stretching device is characterized in that the front end of the bolt stretching device is a steel cable clamp, and the rear end thereof is a membrane edge clamp, threaded holes are formed on the two sides of one of the clamps, through holes are formed on the two sides of the other clamp, two bolts respectively penetrate the threaded holes on one clamp and the through holes on the other clamp, and screwed through nuts positioned outside the through holes; The bolts are coarse thread bolts. The stretching device has the advantages the membrane structure can be rapidly connected with the steel cable; In the stretching process, the stroke is easy to control, the prestress applied to the membrane structure is slowly performed, the stretching stress is uniform, and the operation is simple; the processing of the stretching device is also simple, with low material consumption and low price.
Description
Technical field
The utility model relates to a kind of tensioning equipment, and particularly a kind of rope membrane structure prestressing force applies the bolt tensioning equipment.
Background technology
Critical process in the rope membrane structure construction is the stretch-draw to membrane structure, promptly it is applied the prestressing force that adheres to specification, because the characteristic of membrane structure determines that this is a progressive and process slowly, prestressedly applies common one all even longer time of needs.In construction in the past, adopt wire rope euphroe, Lever Blocks or jackscrew to carry out to prestressed the applying of membrane structure.Wire rope euphroe and Lever Blocks are in membrane structure stretch-draw, and stroke should not be controlled, and tensioning speed is too fast, cause tearing of membrane structure easily.And the stretch-draw of jackscrew need be provided with reaction frame, and device is complicated, and difficulty of construction is big, is not suitable for macrocyclic progressively prestressing force and applies.
Summary of the invention:
The purpose of this utility model is to solve rope membrane structure construction of the prior art to adopt the existing the problems referred to above of wire rope euphroe stretch-draw, provides a kind of rope membrane structure prestressing force to apply the bolt tensioning equipment.The utility model design rope membrane structure prestressing force applies the bolt tensioning equipment, it is characterized in that: the front end of bolt tensioning equipment is the cable wire anchor clamps, the rear end is film limit anchor clamps, the both sides of anchor clamps offer screwed hole therein, the both sides of another anchor clamps offer through hole, pass through hole on a screwed hole on the anchor clamps and another anchor clamps respectively by two bolts, and twist and connect by being positioned at the through hole nut outside.It is characterized in that: bolt is the coarse thread bolt.The utility model has the advantages that and fast membrane structure and cable wire to be coupled together.In stretching process, stroke is controlled easily, and the prestressing force that membrane structure is applied slowly carries out, and tension stress is even, and simple to operate.The processing of tensioning equipment is also very simple, and it is few, cheap to consume material.
Description of drawings:
Figure is a structural representation of the present utility model,
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
The specific embodiment:
The front end of bolt tensioning equipment is cable wire anchor clamps 3 among the figure, the rear end is film limit anchor clamps 2, the both sides of anchor clamps offer screwed hole therein, the both sides of another anchor clamps offer through hole, pass through hole on a screwed hole on the anchor clamps and another anchor clamps respectively by two bolts 1, and twist and connect by being positioned at through hole nut outside 5.It is characterized in that: bolt 1 is the coarse thread bolt.
During use, the cable wire anchor clamps of bolt tensioning equipment are fixedlyed connected with cable wire, film limit anchor clamps are enclosed within on the film limit, connect cable wire anchor clamps and film limit anchor clamps with two bolts then, and turn nut with box spanner, realize the stretch-draw of membrane structure, in stretching process, stroke is controlled easily, and the prestressing force that membrane structure is applied slowly carries out, tension stress is even, and simple to operate.The processing of tensioning equipment is also very simple, and it is few, cheap to consume material.
