Description
Technical field
The present invention relates to a kind of technical field of rail traffic, particularly a kind of ballastless track slab mold and demolding of track slab method.
Background technology
Along with the rise of high-speed railway, in order to ensure the high-speed cruising of train on rail, there is the fragment-free track slab replacing traditional railway sleeper system, according to accuracy and the flatness requirement of the structure of existing fragment-free track slab and the high of track plates, existing fragment-free track slab is in manufacturing process, adopt preset die, by mould matched moulds before precast track plate, the method for form removal again after prefabricated.That is,
When adopting Mold Making fragment-free track slab, meeting first will by each mould matched moulds to form the cavity geometry of fragment-free track slab, then accurate adjustment mould is to meet the shape of fragment-free track slab, size, surface parameter, the designing requirements such as inner steel bar arrangement, adjust complete, carry out the making of fragment-free track slab, after non-fragment orbit sheet metal forming, remove again mould to take out fragment-free track slab, adjustment mould is reinstalled again when next block fragment-free track slab makes, due to the shape of fragment-free track slab, size, surface parameter, the design accuracies such as inner steel bar arrangement require very high, the matched moulds of existing template and carry out release method and make fragment-free track slab to remove and there is following problem:
When 1, often opening fragment-free track slab making, all need to reinstall adjustment mould, be difficult to ensure that mould installation accuracy reaches consistent;
2, all will spend considerable time mounting and adjusting mould when often opening fragment-free track slab and making, cause production efficiency lower, and the matched moulds, the demoulding that repeat cause the significant wastage of construction man power and material; Because the designing requirement of fragment-free track slab is very high, also very high to the requirement of mould mounting and adjusting personnel, difficulty of construction is large, higher to construction site space requirement.
There are the problems referred to above in the mould made in view of existing fragment-free track slab, in the urgent need to a kind of all will the novel ballastless track slab mold of matched moulds and form removal and demolding of track slab method again without the need to often to open when track plates makes.
Summary of the invention
To the object of the invention is to overcome in prior art existing existing railway plate die often open track plates produce before and after all need independent matched moulds and form removal, the coherence requests such as the accuracy of often opening track plates causing it to produce and flatness are difficult to the above-mentioned deficiency ensured, and provide a kind of disengaging method that can adopt the reusable fixing track plates production mould do not dismantled and track plates and mould.
