Summary of the invention
The goal of the invention of the utility model provides a kind of steel work prestressing force that is used for and detects adjusting device, has solved the problem of in the past drawing the inconvenience of detection for the cable wire of steel building, and the equipment body is big, shortcomings such as inconvenient installation.
For solving the problems of the technologies described above, the utility model is achieved in that a kind of steel work prestressing force that is used for detects adjusting device, and it is to be made up of steel reaction frame, vertically-displacable jack, Manual pressure transport, shunting oil pressure pipe, top end nut; The steel reaction frame is fastened on the cable wire, and the steel reaction frame withstands on the ground tackle; Leave distance between steel reaction frame and the fastening nut; Described vertically-displacable jack passes the ground tackle hanging bolt, and end face withstands on the two ends of steel reaction frame, and the bottom surface withstands at the bottom of the top of passing the ground tackle screw rod on the nut; Described shunting oil pressure pipe one is terminated at the vertically-displacable jack, other end catcher dynamic pressure transport.
The utility model adopts a steel reaction frame and top end nut to replace original ground tackle and fastening nut, utilizes the top power of vertically-displacable jack, carries out negative drawing, thereby reaches the purpose of tension cable wire.And then calculate through the oil pressure pressure of jack, calculate corresponding data, finally fastening nut is regulated, to the dual purpose that detects and regulate.
Technique scheme is done further refinement; Described steel reaction frame is to be made up of two plate clamps and lock bolt; The centre of every monolithic anchor clamps is provided with the semicircle boss that supplies cable wire to pass, and is provided with the screw that supplies lock bolt to be horizontally through in the bilateral symmetry of anchor clamps.The present technique scheme has been done further improvement and optimization to technique scheme; Adopt the form of assembly unit to accomplish the steel reaction frame; And then the construction in being more convenient for operating; In addition the centre of every monolithic anchor clamps is provided with the semicircle boss that supplies cable wire to pass, its objective is that to make the steel reaction frame farther from fastening nut, thereby can further strengthen the distance of stretching.
Technique scheme is done further to improve, and the both sides of described every monolithic anchor clamps are provided with the semicircle that supplies fastening nut to pass.Set up these two semicircles in the steel counter-force and further strengthen the distance that stretches on the basis of case up.
Technique scheme is done further to improve, Manual pressure conveyer output port, but be provided with pressure meter and direct-reading Suo Li detection data.In order to reach the purpose of detection, at Manual pressure conveyer output port, but be provided with pressure meter and direct-reading Suo Li detection data, can calculate according to data, thereby regulate according to data again, finally reach the dual purpose that detects and regulate.
Technique scheme is done further to improve; For convenient practical operation; Sometimes because distance, the restriction in place, the overall height of steel reaction frame and vertically-displacable jack is not enough to push up ground tackle; At this moment can between top end nut and vertically-displacable jack, can be provided with the roll adjustment pad, to reach the effect of flexible.
Technique scheme is done further to improve,,, therefore will consider the falling object from high altitude problem, so with belt on described steel reaction frame because of its operation generally is in work high above the ground in order to play safety effect; Be fixed on the steel work.
The advantage of the utility model: device miniaturization, light and handy, portable, be suitable for the operation of various building constructions and small space, safe and reliable, test order of accuarcy reaches national regulation standard and respond well.
Description of drawings
Fig. 1 is the utility model user mode figure.
Fig. 2 is the sketch map of this steel reaction frame.
The specific embodiment
For the structure of clearer and more definite product, annexation is done further to describe below in conjunction with accompanying drawing.
As shown in the figure, a kind of steel work prestressing force that is used for detects adjusting device, and it is to be made up of steel reaction frame 3, vertically-displacable jack 4, Manual pressure transport 7, shunting oil pressure pipe 6, top end nut 5; Steel reaction frame 3 is fastened on the cable wire 8, and steel reaction frame 3 withstands on the ground tackle 1; Described steel reaction frame 3 is to be made up of two plate clamps and lock bolt; The centre of every monolithic anchor clamps is provided with the semicircle 34 that supplies cable wire to pass; The middle upper portion of monolithic anchor clamps is provided with the boss 31 of semicircle, is provided with the screw 32 that supplies lock bolt to be horizontally through in the bilateral symmetry of anchor clamps.The both sides of described every monolithic anchor clamps are provided with the semicircle 33 that supplies fastening nut to pass.Leave distance between steel reaction frame 3 and the fastening nut 2; Described vertically-displacable jack 4 passes ground tackle 1 hanging bolt, and end face withstands on the two ends of steel reaction frame 3, and the bottom surface withstands on passes ground tackle screw rod top end nut; Described shunting oil pressure pipe 6 one is terminated at vertically-displacable jack 4, other end catcher dynamic pressure transport.Manual pressure transport 7 output ports, but pressure meter and direct-reading Suo Li detection data be provided with.
