Abstract

The utility model discloses a track structure of a monolithic track bed capable of being assembled rapidly. The track structure comprises a track board and steel rails erected on the track board through buckling pieces. The track board is fixedly arranged a below-the-line foundation through supporting seats. Compared with the prior art, the supporting seats arranged between the below-the-line foundation and the track board can support the track board effectively so that rapid installation and location of the track board can be achieved, and the requirement that a train can travel on the rail after the track structure is installed is met. The track structure has the advantages of being high in efficiency and precision and convenient to construct. The track structure of the monolithic track bed capable of being assembled rapidly can be well applied to maintenance in skylight time or monolithic roadbed changing under the circumstance that driving conditions are not interrupted.

Description

But a kind of track structure of quick assembled type solid concrete roabed

Technical field

The utility model relates to the railroad track technical field, but refers to particularly it is a kind of track structure that high-speed railway, common railway, subway, administrative region of a city railway etc. are newly-built, reconstruct, run the quick assembled type solid concrete roabed in maintenance that is applied to.

Background technology

At present, domestic and international various types of solid concrete roabed structure, maintenance workload is few, simple in structure owing to having, globality reaches by force the plurality of advantages such as the surface is clean and tidy, at home and abroad all use in a large number on railway, such as German Rehda double-block type ballastless track, Borg slab non-fragment orbit, Japanese the Shinkansen plate-type ballastless track, ladder-type sleepers formula solid concrete roabed, domestic CRTS I type, II type, III plate-type non-fragment orbit, CRTS I type double-block type ballastless track etc., but there is following problem in it in the practice process:

The solid concrete roabed structure is the support on lower basis (the concrete bearing structure on bridge, tunnel, roadbed) online, need to adopt concrete to build under track plates and line between the basis, therefore the certain setting time of material require that adopts when track laying, be after track structure has been laid, need certain curing time; Therefore, because track structure can not be realized the condition that track just can be driven a vehicle immediately after laying is completed, can not adapt to present high-speed railway, the maintenance requirement of subway in the operation process, namely can not satisfy driving when needing repairing at track structure, just can satisfy immediately the requirement of driving a vehicle after can not realizing keeping in repair in the Window time of 3-4 hours.

The utility model content

The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, but provides a kind of to realize that track just can satisfy the track structure of the quick assembled type solid concrete roabed of driving condition after laying is completed.

The technical solution of the utility model is: but a kind of track structure of quick assembled type solid concrete roabed, it comprises track plates and is located at rail on track plates by fastener frame, described track plates is fixedly installed on online lower basis by bearing.

The utility model on the basis, arranges rail and fastener with prefabricate track plates under the mode of employing bearing is fixed online subsequently on track plates, realize can satisfying driving condition after Fast Installation.

In such scheme:

Described bearing is arranged on track plates bottom surface or a part and is arranged on track plates inside, the outstanding track plates of another part.

Vertical both sides of the basic plate that gets on the right track are provided with baffle plate under described line, are used for keeping the laterally fixing of track plates.

Than prior art, bearing between online lower basis and track plates is set, can effectively support track plates, can realize the Fast Installation location of track plates, and realize to satisfy after installation the requirement of train travel, possess that efficient is high, precision is high, the advantage of easy construction, and the utility model can well be applied to need to be in the situation that the condition that do not cut off traffic, repair or replace in solid concrete roabed at Window time and use, have advantages of that present various solid concrete roabed structure is incomparable.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not consist of restriction to the utility model.

But the track structure of a kind of quick assembled type solid concrete roabed as shown in Figure 1 and Figure 2, it comprises track plates 1 and is erected at rail 3 on track plates 1 by fastener 2, its special character is, track plates 1 is to be fixedly installed on online lower basis by bearing 4, than prior art, the bearing 4 between online lower basis and track plates 1 is set, can effectively track plates 1 be supported, can realize the Fast Installation location of track plates 1, and realize to satisfy after installation the requirement of train travel.

Bearing 4 in the present embodiment can be arranged on track plates 1 bottom surface or a part and be arranged on track plates 1 inside, the outstanding track plates 1 of another part.

Get on the right track vertical both sides of plate 1, online lower basis are provided with baffle plate 5, and baffle plate 5 can be used for keeping the laterally fixing of track plates 1.

In the present embodiment, bearing can be realized the adjustment of height, horizontal direction, and possesses the vertical and horizontal fastness function.Bearing can have elasticity, such as adopting rubber or macromolecular material to make, can possess the vibration and noise reducing performance.

The form of structure of bearing 4 can have multiple:

As shown in Figure 3, Figure 4, described bearing 4 is a single cylinder;

As Fig. 5, shown in Figure 6, described bearing 4 is large cylinder 4.1 and small cylinder 4.2, and large cylinder is provided with groove 4.3 in the middle of 4.1 upper surfaces, and small cylinder 4.2 is arranged in groove 4.3;

As Fig. 7, shown in Figure 8, described bearing 4 is large cylinder 4.1 and small cylinder 4.2, and large cylinder 4.1 upper surfaces are provided with groove 4.3, a lateral opening of groove 4.3, and small cylinder 4.2 is arranged in groove 4.3;

Some structures of above-described bearing 4 form, be not the utility model is confined to shown in and described concrete structure in, such as can change cylinder into square body etc., every corresponding modify that might be utilized and equivalent all belong to the scope of the claims of the utility model application.
