Embodiment Construction

[0023] The fixing device for the track slab and the cement emulsified asphalt mortar formwork includes a number of track plate pressing parts 1 and formwork fixing parts 2 as well as screw rods 5 respectively threaded on the two. The screw rods 5 are screwed on the upper end face to be flush with the upper surface of the concrete base On the insulating sleeve 6, a lower end cover 7 is fixed at the lower end of the insulating sleeve 6, the outer cylindrical surface of the insulating sleeve 6 is threaded, and the outer cylindrical surface of the insulating sleeve 6 is fixed with a non-slip strip 8. The rail plate pressing member 1 includes two horizontally placed pressing channels 9 with a vertical gap between the waists. The front end of the pressing channel 9 is fixed with a lower pressing plate 10 whose lower end is lower than its lower end, and the pressing groove The back end of the steel 9 is provided with a vertically placed support channel 11, the upper waist of the suppor...

Abstract

The invention particularly relates to a method and device for fixing a track plate and a cement emulsified asphalt slurry template, solving the problems of time and labor consuming, high cost, influences on insulativity of a concrete base steel bars and the durability of a concrete base. A screw rod is screwed on an insulation sleeve with the upper end face level with the upper surface of the concrete base, the lower end of the insulation sleeve is fixed to a lower end cover, and a cylindrical surface outside the insulation sleeve is in a thread shape and is fixed to an anti-skidding strip. The invention has the advantages of eliminating the drilling procedure on the surface of concrete, and saving the dismantling procedure of a later-stage preembedding member and the sealing procedure ofcavity grouting. The insulation sleeve can be used for the later-stage maintenance of the ballastless track; meanwhile, the pulling-resisting capacity and the skid resistance of the insulation sleeveand the insulativity of the concrete base are ensured.

Description

Technical field [0001] The invention relates to a slab-type ballastless track construction technology, in particular to a fixing device and method for a track slab and a cement emulsified asphalt mortar template. Background technique [0002] After the track slab is fine-tuned in the construction of the slab ballastless track, when the cement emulsified asphalt mortar is poured, there are currently three construction methods to prevent the track slab from floating and displacement and to fix the mud emulsified asphalt mortar template: 1. Drill holes on the concrete base, and bury steel bars to connect with the pressing device for fixing. 2. Drill holes in the concrete on the outer side of the track slab, and fix it by embedding expansion bolts and connecting the pressing device. 3. Drill holes in the concrete on the outer side of the track slab, and fix it by embedding the top blast bolts to connect with the pressing device. [0003] The first method is relatively simple. However...
