Description
Technical field
The utility model relates to the plate-type ballastless track construction technology, is specially the fastening devices of a kind of track plate and cement emulsified asphalt mortar template.
Background technology
At in the plate-type ballastless track construction to behind the track slab precision adjustment, when the cement injection emulsified asphalt slurry, prevent the track plate occur come-up and displacement and fixedly the job practices of mud emulsified asphalt slurry template have three kinds at present: one, on the concrete bed outside the track plate, hole, and bury reinforcing bar underground and the hold down gag ways of connecting is fixed.Two, on the concrete in the track plate outside, hole, bury expansion bolt underground and the hold down gag ways of connecting is fixed.Three, on the concrete in the track plate outside, hole, bury the top explosion bolt underground and the hold down gag ways of connecting is fixed.
First method is easier, but, for fixing embedded bar has certain uplift resistance, must be in hole perfusion resin or special glue, both inconvenient when removing reinforcing bar in the later stage, sometimes the reinforcing bar that will expose cuts away, and stays a part of reinforcing bar in the cavity, or extracts back perfusion mortar sealing in hole at reinforcing bar.Later stage work is loaded down with trivial details, and the durability of concrete bed is constituted a threat to.
Though second method does not need to fix expansion bolt with special glue,, more loaded down with trivial details in the actual installation process, and the expansion bolt installation position is equipped with height and has lowly, exceeds also need cutting away of concrete bed surface.
The third method is comparatively advanced, still, with the method for using expansion bolt common shortcoming is arranged, and there have height to have when installing exactly to be low, exceeds also need cutting away of concrete bed surface, and what be lower than the concrete bed surface also needs the cement mortar shutoff.
More than three kinds of methods all be to hole building on the concrete bed of finishing, bury built-in fitting underground, bore 4-6 hole on the concrete bed of track panel area, waste time and energy, and cost is higher, and, also can influence the insulating properties of concrete bed reinforcing bar at the scene in the drilling construction because the built-in fitting that adopts is steel part, the improper meeting of borehole sealing simultaneously exerts an influence to the durability of concrete bed.
Summary of the invention
The utility model is wasted time and energy for the fixing means that solves track plate and cement emulsified asphalt mortar template exists, the cost height, easily influence the insulating properties of concrete bed reinforcing bar and influence the problem of the durability of concrete bed, and the fastening devices of a kind of track plate and cement emulsified asphalt mortar template is provided.
The utility model is to adopt following technical scheme to realize: the fastening devices of track plate and cement emulsified asphalt mortar template, comprise some track plate compressing members and template fixture and be through screw rod on both respectively, screw rod is screwed on the insulating sleeve of upper surface and concrete bed upper surface flush, the insulating sleeve lower end is fixed with bottom end cover, the insulating sleeve external cylindrical surface is shaped as shape of threads, and the insulating sleeve external cylindrical surface is fixed with reeding.By insulating sleeve being set, do not influence the insulating properties of concrete bed reinforcing bar in the time of time saving and energy saving on the concrete bed surface; Do not have later stage work simultaneously, reduced cost when not influencing the durability of concrete bed; The insulating sleeve external cylindrical surface is shape of threads and is provided with reeding, has improved the resistance to plucking ability and the skid resistance of insulating sleeve.
Track plate compressing member comprises the channel-section steel that compresses that leaves vertical gap between two horizontal positioned and two waists, the front end that compresses channel-section steel is fixed with the lower platen that the lower end is lower than its lower end, the rear end that compresses channel-section steel is provided with the support channel-section steel of vertical placement, support waist place, channel-section steel top and compress the channel-section steel rear end and fix by junction plate, and support channel-section steel waist of lower part place is fixed with the bottom surface and has the base of recess supports on concrete bed, during work, screw rod is through the place, slit that compresses between the channel-section steel, on the screw rod that compresses above the channel-section steel, be screwed with nut then, at this moment swivel nut can be realized track plate compressing member compressing the track plate, base is provided with groove simultaneously, improved the non-skid property of track plate compressing member, structure design is more rationally reliable, prevents that the track plate from having improved the control accuracy to the track plate when come-up and displacement problem occurring.
The template fixture comprises the two fixing block plates that meet at right angles, and is fixed with reinforcing rib between two steel plates, all has screw hole on the block plate of reinforcing rib both sides, and bolt is all rather arranged on another block plate of reinforcing rib both sides.During work, screw rod passes screw hole, and on the screw rod above the screw hole, be screwed with nut the template fixture is fixed, the front and back position of regulating bolt this moment can be realized fixing to the cement emulsified asphalt mortar template, sets up reinforcing rib and makes that the structure setting of template fixed head is more reliable and more stable.
The fixing means of track plate and cement emulsified asphalt mortar template adopts the quantity and the installation site of formulating insulating sleeve before following steps: a, the concreting base; B, concrete bed vertically are pressed into the installation site with insulating sleeve after building and propose the slurry leveling, flush with concrete surface to the insulating sleeve upper surface; C, finish to track slab precision adjustment after, control the fixing of track plate compressing member and template fixture in the insulating sleeve by screw rod is screwed into, accurately check fixed error then.
The utility model is by pre-buried insulating sleeve in concrete floor, saved bore operation operation at concrete surface, avoided the problem of the easy drilled wound of reinforcing bar in the concrete bed in the time of time saving and energy saving, and saved the later stage built-in fitting and removed flow chart and cavity grouting sealing operation operation, and do not produce waste material, insulating sleeve can be used for the later stage to non-fragment orbit maintenance and maintenance, the insulating properties of concrete bed have been guaranteed simultaneously, reeding is set up on insulating sleeve top, has guaranteed the resistance to plucking ability and the skid resistance of insulating sleeve.
With every kilometer (two-wire) plate-type ballastless track construction is example: adopt existing method, it is 310 to 400 that track plate (the every long 5m to 6.45 of plate) is laid quantity, and its drilling hole amount is a hole, (310 to 400) * (4 to 6)=1240 to 2400; Can boring 50 holes for each person every day, according to every day 50 of cement injection emulsified asphalt slurries calculate, need every day 4 people carry out bore operation, need to bore 12 days, and need four Churn drills; And adopt fastening devices described in the utility model, and can save required human and material resources of above-mentioned operation and energy consumption.
