Abstract
The utility model discloses a temporary fixing bracket shaped like a Chinese character ''yi'', which is characterized by comprising a fixing bracket (1) shaped like a Chinese character ''yi'' and a bed plate (2), wherein, the cross section of the fixing bracket (1) is of a reversed U-shape, the two ends of the lower part of the fixation bracket (1) are connected with the bed plate (2), the bed plate (2) is vertical to the fixing bracket (1), the upper part of the fixing bracket (1) is equipped with a hole with a screw anchor (3). The screw anchor (3) is equipped with a wing profile nut (4) and a briquette (5). The utility model solves the difficult problems including the upward floating of the straight line section of the track plate, the upward floating and the transverse sliding of the curved section of the track plate during the grouting mortar process of the track plate and eliminates the potential quality troubles caused by the plate grouting.
Description
Technical field
The utility model relates to fixed mount, especially relates to a kind of temporary fixed of in-line that ballastless track boards plays fixation that is used for.
Background technology
The structure of ballastless track of high-speed railway is made up of bridge floor or roadbed, bed plate concrete or hydraulicity supporting layer, asphalt cement mortar layer, track plate, rail and rail fastening on track slab system.Build non-fragment orbit and at first built bridge floor or roadbed, bed plate concrete or hydraulicity supporting layer, then laid rail guidance tape and accurately adjust according to the line design key element.The track plate that lays need carry out temporary fixed, and then lays long rail on the track plate, and the utility model is exactly to play temporary fixed function.
The utility model content
The purpose of this utility model provides temporary fixed of a kind of in-line that prevents track plate come-up or laterally slippage.
The technical solution adopted in the utility model: constitute by fixed mount that is in-line and bed plate, wherein the cross section of fixed mount is the ∏ type, on two ends, fixed mount bottom, be connected with bed plate, bed plate and fixed mount are perpendicular, above fixed mount, have the hole, be installed with threaded anchor rod in the hole, have aerofoil profile nut and briquetting on the threaded anchor rod.
Described fixed mount outer face and the outer face of bed plate on vertically transversely is positioned on the same horizontal plane; The lateral length of bed plate is wider than the longitudinal length of fixed mount.
The utility model is before the track plate is extensive, threaded anchor rod is anchored on the track plate base, threaded anchor rod is between two track plates, behind the track slab precision adjustment, the utility model fixed mount upper aperture is through on the threaded anchor rod, the bed plate at two ends, fixed mount bottom is shelved on respectively on the track plate of both sides, by the aerofoil profile nut on the threaded anchor rod the utility model is pressed on the track plate.The utility model is no tiny fragments of stone, coal, etc. track slab pavement temporary fastening device when building, and it mainly acts on is temporary fixed track plate, in order to avoid track plate generation displacement during grouting.
The beneficial effects of the utility model: the utility model has solved the difficult problem of track plate perfusion CA mortar process cathetus location track plate come-up and curve location track plate come-up and horizontal slippage, has eliminated owing to irritating the hidden danger of quality that plate produces; Extensively utilization has fabulous market prospects in track slab construction.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is and the matching used threaded anchor rod structural representation of the utility model;
Fig. 4 is the utility model and the threaded anchor rod structural representation when being used.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
The structure that a kind of in-line of the utility model is temporary fixed such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, constitute by fixed mount 1 that is in-line and bed plate 2, wherein the cross section of fixed mount 1 is the ∏ type, on two ends, fixed mount 1 bottom, be connected with bed plate 2, bed plate 2 is perpendicular with fixed mount 1, above fixed mount 1, have hole a, be installed with threaded anchor rod 3 in the hole, have aerofoil profile nut 4 and briquetting 5 on the threaded anchor rod 3.
It is temporary fixed that the utility model is mainly used in the track plate in straight line and curve location.Mounting means is:
1, before the track plate is extensive, electricity consumption is drilled in the hole that the about deeply 200mm of φ 20mm is bored in the precalculated position on the track plate bed plate concrete near measuring disjunction mark.
2, filling bar planting glue in the hole, and insert threaded anchor rod 3.
3, after track slab precision adjustment and bar planting gelling are solid, the yi word pattern temporary fastening device are installed, and are tightened aerofoil profile nut 4 and briquetting 5 compresses.
Claims (2)
1, a kind of in-line is temporary fixed, it is characterized in that: constitute by fixed mount that is in-line (1) and bed plate (2), wherein the cross section of fixed mount (1) is the ∏ type, on fixed mount (1) two ends, bottom, be connected with bed plate (2), bed plate (2) is perpendicular with fixed mount (1), has hole (a) in fixed mount (1) top.
2, in-line according to claim 1 is temporary fixed, it is characterized in that: be installed with threaded anchor rod (3) in the hole (a) of fixed mount (1) top, have aerofoil profile nut (4) and briquetting (5) on the threaded anchor rod (3).
