Description
Technical field
The utility model belongs to the dual-direction pre-tensioning system prestressed track plate prefabrication technical field of high-speed railway CRTS III plate-type non-fragment orbit, is specifically related to a kind of adjustable connector for CRTS III type track plate prefabrication.
Background technology
CRTS III plate-type non-fragment orbit is up-to-date brand-new, the ballastless track structure system with complete independent intellectual property right developed of China, CRTS III type pretensioning prestressed concrete track plates is the important component part of CRTS III plate-type ballastless track structure, be at factorial praluction, then lay to on-the-spot.
Bidirectional pre-tensioned prestressed concrete railway board adopts matrix unit to produce, each unit is 2 × 4 pieces of track plates models, adopt deformed bar fixed-length blanking, track plates side scheme is not exposed in conjunction with deformed bar, deformed bar two ends arrange tension rod, the corresponding tension rod of adjacent forms is connected by connector, and make deformed bar realize integral tension, Synchronous Radio is opened.But below the connector ubiquity adopted at present, some is not enough: 1. after Synchronous Radio is opened, owing to also having residual stress between adjacent forms, connector is by the tension dismounting very difficulty of two ends tension rod; 2. because designing requirement is less than 1.0mm to ensure anchor plate location consistency in a template along presstressed reinforcing steel direction length variation, therefore, at the scene in the middle of practical operation, need to realize the position of anchor plate in template by adjusting the tension rod of canned paragraph, and be not more than ± 2mm due to presstressed reinforcing steel processing length designing requirement deviation; Therefore, be difficult to adjust to design attitude.
Summary of the invention
The utility model is solve to adopt current connector dismounting difficulty, is difficult to the technical problem of adjustment anchor plate position in a template, provides a kind of adjustable connector for CRTS III type track plate prefabrication.
The technical solution adopted in the utility model is as follows:
A kind of adjustable connector for CRTS III type track plate prefabrication, comprise cylinder shape connector main body and slotted nut, cylinder shape connector body shaft is to establishing the female through hole in two ends, cylinder shape connector main body two ends are also symmetrically arranged with convex open slot, the inner side width of rebate of convex open slot is greater than outside width of rebate, the bar footpath of outside width of rebate and tension rod adapts, the diameter of the hexagonal structure of inner side width of rebate and tension rod end adapts, and the length of inner side notch is greater than the length of the hexagonal structure of tension rod end; Described slotted nut is elongated fluting in the axial direction, and groove width is consistent with the outside width of rebate of cylinder shape connector main body, and external screw thread and the through hole internal thread of slotted nut adapt.
When using the utility model to carry out connection tension rod, only tension rod need be put into cylinder shape connector main body along open slot, then with slotted nut, tension rod be screwed, during dismounting, slotted nut does not need whole back-out, only needs to revolve a few circle, and after tension rod loosens, aligned notches namely removably.
The utility model structure is simple, uses and dismantles all very convenient, and conveniently can adjust tension rod to regulate anchor plate position in a template, improve efficiency of construction, ensure that track plate prefabrication quality.

Detailed description of the invention
As shown in Figure 1, a kind of adjustable connector for CRTS III type track plate prefabrication, comprise cylinder shape connector main body 1 and slotted nut 2, as Fig. 2, shown in 3, cylinder shape connector main body 1 axially establishes the female through hole in two ends, cylinder shape connector main body 1 two ends are also symmetrically arranged with convex open slot, the inner side width of rebate of convex open slot is greater than outside width of rebate, the bar footpath of outside width of rebate and tension rod 3 adapts, the diameter of the hexagonal structure of inner side width of rebate and tension rod 3 end adapts, the length of inner side notch is greater than the length of the hexagonal structure of tension rod 3 end, as shown in Figure 4,5, described slotted nut 2 elongated fluting in the axial direction, groove width is consistent with the outside width of rebate of cylinder shape connector main body 1, and external screw thread and the through hole internal thread of slotted nut 2 adapt.
As shown in Figure 1, when using the utility model to carry out connection tension rod, only tension rod 3 need be put into cylinder shape connector main body 1 along open slot, with slotted nut 2, tension rod 3 is screwed again, during dismounting, slotted nut 2 does not need whole back-out, only needs to revolve a few circle, and after tension rod 3 loosens, aligned notches namely removably.
The utility model structure is simple, uses and dismantles all very convenient, and conveniently can adjust tension rod to regulate anchor plate position in a template, improve efficiency of construction, ensure that track plate prefabrication quality.
