The base plate is disc-shaped, is provided with an equihexagonal through hole in the middle, and can be sleeved on the periphery of the nut in a fitting manner; the push rod is in an inverted U shape, and the end part of the opening end of the push rod is fixed on the upper surface of the chassis and symmetrically positioned on the central line of the chassis. The utility model relates to a rationally, simple structure, convenient to use can effectively overcome the restriction of space environment in the construction, and convenient and fast fastens or dismantles finish rolling screw thread muscle nut, makes the efficiency of construction promoted by a wide margin.
Description
Technical Field
The utility model relates to a bridge construction structure, especially a fastener, specific fastener of finish rolling screw thread muscle nut that says so.
Background
At present, a steel wrench is mostly used for fixing and tightening the nut. However, in the vertical prestressing construction of a bridge structure, it is often necessary to fasten nuts on finish-rolled threaded bars. The positions of finish-rolled threaded bars are often in steel bar clusters, and force cannot be applied when a wrench is used for tightening nuts, so that great inconvenience is brought to construction, and improvement is urgently needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at prior art not enough, provide a fastener of finish rolling screw thread muscle nut, can effectively overcome the space environment limit in the construction, convenient and fast fastens or dismantles finish rolling screw thread muscle nut, makes the efficiency of construction promoted by a wide margin.
The technical scheme of the utility model is that:
a fastening device for a finish-rolled threaded rib nut comprises a chassis and a push rod. The base plate is disc-shaped, is provided with an equihexagonal through hole in the middle, and can be sleeved on the periphery of the nut in a fitting manner; the push rod is in an inverted U shape, and the end part of the opening end of the push rod is fixed on the upper surface of the chassis and symmetrically positioned on the central line of the chassis.
Further, the chassis is made of a steel plate.
Further, the push rod is made of round steel.
The utility model has the advantages that:
the utility model relates to a rationally, simple structure, convenient to use can effectively overcome the restriction of space environment in the construction, and convenient and fast fastens or dismantles finish rolling screw thread muscle nut, makes the efficiency of construction promoted by a wide margin.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1-a chassis; 2-a through hole; and 3, pushing the rod.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1.
A fastening device for a finish-rolled threaded rib nut comprises a chassis 1 and a push rod 3. The base plate 1 is disc-shaped, and an equihexagonal through hole 2 is formed in the middle. The diameter of the through hole 2 is adapted to the nut to be fastened, so that the through hole can be conveniently and stably sleeved on the periphery of the nut. The push rod 3 is in an inverted U shape, the end part of the opening end of the push rod is welded on the upper surface of the chassis 1 and symmetrically located on the central line of the chassis, and the push rod can drive the chassis to rotate through the axial rotation of the push rod.
The chassis 1 is made of a steel plate, and the thickness of the chassis is 1.5-2 cm.
The push rod 3 can be made of round steel with phi of 16 mm. The height of the push rod 3 is about 45cm, so that the push rod can bear force and can be higher than the height of a steel bar head on a common construction site, and the operation is convenient.
When the nut screwing device is used, the chassis is vertically sleeved on the nut, then a reinforcing steel bar torsion bar with the diameter of more than 20mm or other similar rod-shaped objects penetrate through the neutral gear in the middle of the push rod, and the push rod is rotated clockwise or anticlockwise according to the tightness requirement, so that the push rod drives the chassis to rotate, and the nut is screwed or unscrewed.
The utility model discloses the part that does not relate to all is the same with prior art or can adopt prior art to realize.
