Abstract
A mounting nut for a pre-stress steel bar comprises a mounting nut for a fixing end and a mounting nut for a stretching end. Both the mounting nut for the fixing end and the mounting nut for the stretching end are provided with a threaded sleeve. The inner diameter of the threaded sleeve is slightly bigger than the diameter of the pre-stress steel bar. A section of screw thread is arranged in the middle of the inner wall of the threaded sleeve. A magnetic ring is concentrically embedded on the tail end of the threaded sleeve. The end head of the threaded sleeve is expanded and a locating surface is formed towards one side of the tail of a locating column. A locating column having a locating column end head is fixed inwards to the threaded section from a sleeve end head of the mounting nut for the fixing end. The nut has simple and reliable structure, convenient manufacturing and low cost, ensures the reliable mounting of an anchor plate, simplifies the installing technique of the anchor plate, decreases the type and the quantity of construction tool and the labor intensity of workers, accelerates the construction progress, saves a large amount of working time and realizes the rapid mounting of the pre-stress steel bar.

Background technology
In the past in the track plate prefabrication process, connect the installation nut employing plain nut that prestressed steel bar is used, plain nut is connected by bolt with anchor plate, because the quantity of prestressed steel bar and anchor plate is various, aforesaid operations will cause sizable workload, makes installation effectiveness low; Simultaneously, the axial location of prestressed steel bar all is by range estimation or by survey tool, and the position that range estimation is installed is accurate inadequately, can make installation effectiveness become low again by survey tool.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of mounting nut of prestressed steel bar, solve prestressed steel bar and the low technical problem of anchor plate installation effectiveness; And the accurate inadequately problem in the axial installation site that solves prestressed steel bar and anchor plate.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of mounting nut of prestressed steel bar, comprise that stiff end is installed nut and the stretch-draw end is installed nut, it is characterized in that: described stiff end is installed by nut and stretch-draw end installation nut all has a threaded sleeve, the internal diameter of threaded sleeve is slightly larger than the diameter of prestressed steel bar, there is one section screw thread at the middle part of threaded sleeve inwall, be embedded with a magnet ring on the tail end face of threaded sleeve with one heart, expand the sleeve pipe termination of threaded sleeve, forming locating surface towards reference column afterbody one side, the sleeve pipe termination of stiff end installation nut inwardly is fixed with the reference column of a band reference column termination to thread segment.
Be welded to connect between the reference column termination of described reference column and the sleeve pipe termination of threaded sleeve.
Described termination can be square toes, turret head or interior hexagonal socket cap.
The beneficial effects of the utility model are as follows:
The utility model is for the prefabricated speed of accelerating the track plate, improves track plate production efficiency and a kind of novel pre-stressed rod iron developed is installed nut, is divided into that stiff end is installed nut and the stretch-draw end is installed two kinds on nut.Stiff end is installed the double action that nut plays locking and location prestressed steel bar, and the stretch-draw end is installed nut can effective fastening prestressed steel bar, realize the Fast Installation of prestressed steel bar.
The utility model is installed the screw-in depth of the reference column in the nut by limiting stiff end, the axial installation site of control prestressed steel bar.By installing at stiff end on nut end face, the stretch-draw end installation nut end face magnet ring is installed, is replaced bolt to connect, reach the purpose of Fast Installation anchor plate with magnet ring.
The utility model is simple and reliable for structure, and is easily manufactured, with low cost, can realize the quick positioning and locking of prestressed steel bar.The utility model relies on the suction of magnet ring, has guaranteed the reliable installation of anchor plate, has simplified the mounting process of anchor plate, has reduced kind, quantity and the working strength of workers of job site instrument, has accelerated construction speed, has saved a large amount of man-hours.The utlity model has easy construction, quick, characteristics simple to operate can guarantee that the quality of track plate has very high stability and reliability when producing in enormous quantities.
