Abstract
The invention discloses a mounting nut of a prestressed steel bar, which comprises a fixed-end mounting nut and a stretch-end mounting nut that are respectively provided with a threaded sleeve; the inside diameter of the threaded sleeve is slightly larger than the diameter of the prestressed steel bar; the middle part of the inner wall of the threaded sleeve is provided with a section of threads;the end surface of the tail part of the threaded sleeve is embedded with a magnet ring in a concentric way; the sleeve end of the threaded sleeve expands and forms a locating surface towards one sideof the tail part of a locating column; and the sleeve end of the fixed-end mounting nut is fixed with the locating column with a locating column end inwards to the thread section. The nut has simple and reliable structure, convenient manufacture and low cost, ensures the reliable installation of an anchor backing plate, simplifies the installation process of the anchor backing plate, reduces the tool kind and amount in the construction site and the labor intensity of the workers, quickens the construction progress, saves a great deal of working hours, and realizes the fast installation of theprestressed steel bar.
Description
Technical field
The present invention relates to a kind of nut that is connected on the railway plate die, is used for the prestressed rod iron.
Background technology
In the past in the track plate prefabrication process, connect the installation nut employing plain nut that prestressed steel bar is used, prefabricated anchor plate is to adopt bolt that anchor plate is connected with the anchor recess mould, 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.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention 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 solution adopted for the present invention to solve the technical problems 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.
Beneficial effect of the present invention is as follows:
The present invention 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 present invention installs the degree of 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 present invention 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 present invention 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 present invention has easy construction, quick, and characteristics simple to operate can guarantee that the quality of track plate has very high stability and reliability when producing in enormous quantities.

Reference numeral: 1-magnet ring, 2-threaded sleeve, 3-reference column, 3.1-reference column termination, 4-sleeve pipe termination, 5-screw thread, 6-railway plate die, 7-anchor plate, 8-stiff end anchor recess mould, 9-stretch-draw end anchor recess mould, 10-prestressed steel bar, 11-stiff end are installed nut, 12-stretch-draw end is installed nut.
The specific embodiment
Embodiment is referring to shown in Figure 4, this mounting nut of prestressed steel bar, comprise that stiff end is installed nut 11 and the stretch-draw end is installed nut 12, 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 10, there is one section screw thread 5 at the middle part of threaded sleeve inwall, be embedded with a magnet ring 1 on the tail end face of threaded sleeve with one heart, expand the sleeve pipe termination 4 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 3 of a band reference column termination 3.1 to thread segment, be welded to connect between the reference column termination 3.1 of reference column and the sleeve pipe termination 4 of threaded sleeve.
Described termination 4 is square toes, turret head or interior hexagonal socket cap.
The present invention includes two kinds: stiff end is installed by nut and the stretch-draw end is installed nut, and above-mentioned two kinds of nuts use in pairs.Anchor plate and mounting nut of prestressed steel bar directly paste tight by magnetic force.Prestressed steel bar 10 is installed nut screwing clamping with stiff end earlier, because the position-limiting action of reference column, tighten the other end location of promptly having finished prestressed steel bar when tightening again.
As shown in Figure 1 and Figure 2, stiff end installation nut is made up of threaded sleeve, magnet ring, reference column.Reference column and threaded sleeve welding, magnet ring is embedded in the end face of threaded sleeve, and the other end of threaded sleeve can be made the turret head of being convenient to wrench operated or the termination form that is fit to other tool operation, and the end face of termination 4 is as locating surface is installed.By the length of control reference column, just can control the screw-in depth of prestressed steel bar, can realize the axial location of prestressed steel bar.
As shown in Figure 3, stretch-draw end installation nut is made up of threaded sleeve and magnet ring, and magnet ring is embedded on the end face of threaded sleeve.Threaded sleeve is provided with one section screw thread, and the rear and front end is logical open form formula.
As shown in Figure 4, be connected with stretch-draw end anchor recess mould 9 on the railway plate die 6, threaded sleeve 2 is through 9 li of stretch-draw end anchor recess moulds, and the magnet ring 1 on the threaded sleeve end face holds anchor plate 7, makes the anchor plate 7 and the medial end of stretch-draw end anchor recess mould 9 paste tight.
As shown in Figure 4, be connected with stiff end anchor recess mould 8 on the railway plate die 6, threaded sleeve 2 is through 8 li of stiff end anchor recess moulds, and the magnet ring 1 on the threaded sleeve end face holds anchor plate 7, makes the anchor plate 7 and the medial end of stiff end anchor recess mould 8 paste tight.
