Abstract
The utility model discloses a compressing device for construction of a ballastless track plate, which comprises an L-shaped steel frame, a reinforcing steel bar with external threads and a nut matched with the reinforcing steel bar, wherein the L-shaped steel frame consists of a cross beam and a support beam which are vertical to each other; and a vertical through slot is arranged on the cross beam for the reinforcing steel bar to pass through. Through the compressing function of the cross beam and the tensioning function of the reinforcing steel bar, the displacement of the track plate is limited in the vertical direction, the track plate is ensured not to float in the mortar filling process after fine adjustment, and the construction precision is ensured.
Description
Technical field
The utility model relates to a kind of fragment-free track slab pavement construction equipment, is specifically related to a kind of fragments-free track slab construction hold down gag.
Background technology
Special line for passenger trains non-fragment orbit structure mainly is made up of three parts from top to bottom: track plate, sacked cement emulsified asphalt slurry and concrete bed.In the track slab pavement process, at first accurately be placed on the track plate on the precalculated position with the track slab precision adjustment device, cement injection emulsified asphalt slurry in the infusion bag that between track plate and concrete bed, places in advance then, in filling process, thereby the constraint that is subjected to infusion bag and upper rail guidance tape around the mortar causes track plate come-up, and the location that influences track plate in the vertical direction is accurate.
Therefore, need to explore a kind of hold down gag, guarantee that the track plate after the accurate adjustment is non-rising when mortar injection, guarantee construction precision.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of fragments-free track slab construction hold down gag, can limit the displacement of track plate in the vertical direction, guarantees that the track plate after the accurate adjustment is non-rising when mortar injection, guarantees construction precision.
Fragments-free track slab construction hold down gag of the present utility model, comprise L shaped steelframe, be with externally threaded reinforcing bar and with the screw thread steel nut engaged, described L shaped steelframe is made up of orthogonal crossbeam and brace summer, has the vertical groove that passes for reinforcing bar on the crossbeam.
Further, described brace summer is connected with the horizontal base seat board away from an end end of crossbeam;
Further, described L shaped steelframe and horizontal base seat board are made by channel-section steel;
Further, described vertical groove extends along the crossbeam length direction;
Further, described nut one end is connected with the circular metal backing plate, and the diameter of circular metal backing plate is greater than the groove width of vertical groove;
Further, described nut is a wing nut, is symmetrically connected with two wing bars on its outer wall.
The beneficial effects of the utility model are: in the track slab construction process, after track slab precision adjustment finishes, reinforcing bar is anchored on the concrete bed, and the reinforcing bar that anchoring is finished is in plumbness, after making reinforcing bar pass the vertical groove of L shaped steelframe then, vertically place L shaped steelframe, the crossbeam of L shaped steelframe is closely contacted with the track plate, and brace summer or horizontal base seat board are supported on the concrete bed, overlap top nut at last on reinforcing bar, screw nut, promptly finish the installation of hold down gag, the cement emulsified asphalt mortar perfusion is finished, and mortar expansion is finished, after mortar strength reaches 2MPa, can remove hold down gag; The utility model has limited the displacement of track plate in the vertical direction by the pressuring action of crossbeam and the tension effect of reinforcing bar, guarantees that the track plate after the accurate adjustment is non-rising when mortar injection, has guaranteed construction precision.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
Fig. 1 is a front view of the present utility model, and Fig. 2 is a vertical view of the present utility model; As shown in the figure, fragments-free track slab construction hold down gag of the present utility model, comprise L shaped steelframe, with externally threaded reinforcing bar 1 and with the nut 2 of reinforcing bar 1 threaded engagement, described L shaped steelframe is made up of orthogonal crossbeam 3 and brace summer 4, has the vertical groove 5 that passes for reinforcing bar 1 on the crossbeam 3.
As further improvement of the utility model, described brace summer 4 is connected with horizontal base seat board 6 away from an end end of crossbeam 3; Usage level bed plate 6 is supported on the concrete bed 9, and horizontal base seat board 6 is bigger with the contact surface of concrete bed 9, makes the utility model more firm.
As further improvement of the utility model, described L shaped steelframe and horizontal base seat board 6 are made by channel-section steel; Horizontal base seat board 6 can be made by a channel-section steel, and brace summer 4 also can be made by a channel-section steel; Crossbeam 3 is welded by two blocks of relative channel-section steels, reserves certain distance between them, is vertical groove 5; Use the channel-section steel to be base material, material is simple and easy to, and is easy to make.
As further improvement of the utility model, described vertical groove 5 extends along crossbeam 3 length directions; Vertically groove 5 extends along crossbeam 3 length directions, and flute length is longer, and reinforcing bar 1 can be in move left and right in the vertical groove 5, to regulate the contact length of crossbeam 3 and track plate 11.
As further improvement of the utility model, described nut 2 one ends are connected with circular metal backing plate 7, and the diameter of circular metal backing plate 7 is greater than the groove width of vertical groove 5; Circular metal backing plate 7 has increased the contact area of nut 2 with crossbeam 3, has strengthened fastening force.
As further improvement of the utility model, described nut 2 is a wing nut, is symmetrically connected with two wing bars 8 on its outer wall; When turning wing nut, convenient laborsaving.
In the track slab construction process, after 11 accurate adjustments of track plate finish, reinforcing bar 1 is anchored at (anchorage depth should be 100 ~ 150mm on the concrete bed 9, use epoxy resin to fix), and the reinforcing bar 1 that anchoring is finished is in plumbness, after making reinforcing bar 1 pass the vertical groove 5 of L shaped steelframe then, vertically place L shaped steelframe, the crossbeam 3 of L shaped steelframe is closely contacted with track plate 11, horizontal base seat board 6 is supported on the concrete bed 9, the last nut 2 that puts band circular metal backing plate 7 on reinforcing bar 1 screws nut 2, promptly finishes the installation of hold down gag, cement emulsified asphalt mortar 10 perfusions are finished, mortar 10 expands and finishes, and after mortar 10 intensity reach 2MPa, can remove hold down gag; The utility model has limited the displacement of track plate 11 in the vertical directions by the pressuring action of crossbeam 3 and the tension effect of reinforcing bar 1, guarantees that the track plate 11 after the accurate adjustment is non-rising when mortar 10 perfusions, has guaranteed construction precision.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and the spirit and scope of the present utility model that do not depart from appended claims and limited.
