Abstract
The utility model discloses a special anchor bolt drawing screw driver. The special anchor bolt drawing screw driver comprises a rectangular sleeve, wherein a U-shaped groove with the width which is slightly greater than the diameter of an anchor bolt is arranged in the middle of a rear side face of the rectangular sleeve; the outer side of a front side face of the rectangular sleeve is welded with a nut; the circular-arc center of the U-shaped groove and the center of the nut are on the sane axis; the front side face has a threaded hole which is concentric to the nut. With the adoption of the special anchor bolt drawing screw driver, the stress on the anchor bolt is uniform, the detection data is more accurate, the structure is simple and the design is reasonable.
Description
Technical field
The utility model relates to a kind of plastics crab-bolt detection technique field, especially relate to a kind of plastics crab-bolt pulling capacity bottle opener.
Background technology
?at present, plastics crab-bolt needs to use multiple clamping apparatus in drawing experimentation, original crab-bolt stretching clamp scene needs assembling (with 3 supporting legs), on-the-spot installation is loaded down with trivial details, and height control is inconvenient, the result that this method causes is can not make than more comprehensive reflection integral construction quality, causes test data inaccurate.
In the detection of heat-insulation wall plate crab-bolt tension bearing capacity, traditional way is by structure glue, pull bar and crab-bolt disk to be bonded together, and its defect is: the one, and wait gelling admittedly just can work afterwards; The 2nd, in bonding, may be because little with disk bond area, disc surfaces is clean and bonding not firm not; The 3rd, be difficult for making anchor pole vertical with disk direction in bonding, cause in drawing process pulling force to disperse inhomogeneous, result is produced to relatively large deviation; The 4th, not easy to operate.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of easy to detect, simple in structure, can make crab-bolt uniform stressed, detect more accurate, the reasonable in design Special anchor bolt drawing bottle opener of data.
The utility model technical solution problem provides following scheme:
A Special anchor bolt drawing bottle opener, comprises rectangular sleeve, and the centre on the trailing flank of described rectangular sleeve is provided with the U-shaped groove that width is slightly larger than crab-bolt diameter, and leading flank outside is welded with nut, and the center of arc of described U-shaped groove, the center of nut are on same axis.
On described leading flank, there is the threaded hole concentric with nut.
The width of described U-shaped groove is 12-16mm, and the aperture of described threaded hole, nut is 14mm.
The length of described rectangular sleeve is 60-100mm, and wide is 60-80mm; Wall thickness is 20-30mm.
Adopt a kind of Special anchor bolt drawing bottle opener of said structure, its beneficial effect is: described Special anchor bolt drawing bottle opener, with U-shaped groove and nut, during test, U-shaped draw-in groove is stuck on plastics crab-bolt expansion sleeve, crab-bolt disk is through rectangular sleeve, together with nut is screwed in anchor pole, guarantee that pulling force is applied in the vertical direction of disk, applies pulling force and tests, make crab-bolt uniform stressed, detect accurately, reasonable in design, be convenient to testing staff's execute-in-place, and use the utility model can be more accurate by detecting data, improved accuracy of detection.

Embodiment
With reference to accompanying drawing, a kind of plastics crab-bolt pulling capacity bottle opener, comprises rectangular sleeve 1, and the centre on the trailing flank of described rectangular sleeve 1 is provided with U-shaped groove 2, and leading flank outside is welded with nut 3, and the center of the center of arc of described U-shaped groove 2, nut 3 is on same axis; On leading flank, there is the threaded hole concentric with nut 4; The width of described U-shaped groove 2 is 12mm, and the aperture of described threaded hole 4, nut 3 is 14mm; The length of described rectangular sleeve 1 is 80mm, and wide is 80mm, and wall thickness is 25mm.
During test, U-shaped groove 2 is stuck on plastics crab-bolt expansion sleeve, and crab-bolt disk, through rectangular sleeve 1, together with welded nut 3 is screwed in anchor pole, applies pulling force and tests.
