CN201678920U - Ballastless track board paving no-slip limiting device - Google Patents

Abstract

The utility model discloses a ballastless track board paving no-slip limiting device. The upper surface of a Z-shaped rack (3) is pressed on a track board, and the lower surface thereof is fixed on a base through a fixed bolt hole (4); a screwing anti-floating screw rod (1) is tightly pressed on the upper surface of the track board to prevent the track board from upwards floating; and a screwing no-slip screw rod (2) is tightly pressed on the side of the track board to prevent the track board from transversally sliding. The reinforcing rib (5) can be arranged on the Z-shaped rack (3) so as to ensure the strength of the Z-shaped rack (3). The utility model has simple and compact structure, and solves the problem of the curve section paving of the ballastless track board that the track board floats up and slips downwards.

Description

The anti-skidding stopping means of a kind of fragment-free track slab pavement

Technical field

The utility model belongs to the construction of railways field, relates in particular to a kind of railway ballastless track.

Background technology

Plate-type ballastless track is introduced in the China railways construction since the beginning of this century, wait very much construction of railways through the line that changes then, Beijing-Tianjin inter-city railway, military wide, stone, the non-fragment orbit construction has obtained a large amount of experiences, has obtained certain effect, has promoted the development of China Express Railway effectively.But on Construction Quality Control, particularly in the control of the come-up of CRTS I type track plate and laterally slippage, also there is more problem, also needs us to do further research and discussion.

During the construction of CRTS I type fragment-free track slab pavement, requiring track plate center line allowable variation is 2mm; Track plate top surface elevation allowable variation ± 1mm; Front and back position allowable variation 5mm.Carry out filling bed when grouting after track slab precision adjustment puts in place, the track plate is subjected to the buoyancy that the CA mortar gives and is shifted, thereby makes the position of track plate not reach required precision.And when the freeboard section mortar injection, track plate displacement problem is particularly serious.Do not having under the situation of stopping means, when perfusion CA mortar, the track plate of straightway is easy to generate big come-up situation, then is easy to generate the situation of come-up and downslide at curved section.

The utility model content

The purpose of this utility model is: solve in the construction of CRTS I type fragment-free track slab pavement the problem that curved section then is easy to generate come-up and glides during the CA mortar injection.

The purpose of this utility model is achieved in that by anti-floating screw rod, anti-skidding screw rod, Z type frame and fixed bolt hole to be formed, anti-floating screw rod be installed in Z type frame above, anti-skidding screw rod is installed in the side of Z type frame, and Z type frame can be fixed on the base by the fixed bolt hole on it; Be pressed on the track plate above the Z type frame, then be fixed on the base below, screw anti-floating screw rod, make it press track plate upper surface, prevent track plate come-up by fixed bolt hole; Screw anti-skidding screw rod, make it be adjacent to track plate side, prevent that the track plate from laterally sliding.The utility model is simple in structure, compact, has solved track plate come-up that occurs during the fragment-free track slab curved section is laid and the problem that glides.

Description of drawings

Fig. 1 is a front view of the present utility model.

Fig. 2 is the utility model vertical view.

Fig. 3 is the utility model left view.

Each position and numbering among the figure: anti-floating screw rod 1, anti-skidding screw rod 2, Z type frame 3, fixed bolt hole 4 and reinforcing rib 5.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only is used to explain the utility model, and be not used in qualification the utility model.

Be pressed on the track plate above the Z type frame 3, then be fixed on the base below, screw anti-floating screw rod 1, make it press track plate upper surface, prevent track plate come-up by fixed bolt hole 4; Screw anti-skidding screw rod 2, make it be adjacent to track plate side, prevent that the track plate from laterally sliding.For guaranteeing the intensity of Z type frame 3, can also on Z type frame 3, establish reinforcing rib 5.

Claims (2)

1. anti-skidding stopping means of fragment-free track slab pavement, it is characterized in that forming by anti-floating screw rod (1), anti-skidding screw rod (2), Z type frame (3) and fixed bolt hole (4), anti-floating screw rod (1) be installed in Z type frame (3) above, anti-skidding screw rod (2) is installed in the side of Z type frame (3), and Z type frame (3) can be fixed on the base by the fixed bolt hole on it (4).

2. the anti-skidding stopping means of a kind of fragment-free track slab pavement as claimed in claim 1 is characterized in that reinforcing rib (5) is arranged on the Z type frame (3).
