Abstract
The invention discloses a composite precast concrete rail plate. The composite precast concrete rail plate comprises rail plates and rail bearing platforms at the upper parts of the rail plates, wherein self-compacting concrete filling holes penetrating from top to bottom are arranged in the middle parts of the rail plates; door-type steel bars are arranged at the bottom parts of the rail plates and are embedded in self-compacting concrete layers fixedly connected with the bottom parts of the rail plates; and embedded shear plates are arranged at two ends of each of the rail plates. The composite precast concrete rail plate has the beneficial effect that the rail plate is suitable for any section of high-speed rails and metros. Due to the arrangement of the door-type steel bars and the self-compacting concrete layers, equivalently the structural thickness is increased indirectly and the temperature stress and bridge deflection force resistant capabilities are enhanced; the embedded shear plates are arranged at the two ends of each of the rail plates, so that the rail plates can be connected in sequence in construction, and the shearing force between the rail plates can be well transferred; and therefore, the problem of unsmooth rails due to non-uniform settlement of road foundations is well solved.
Description
Technical field
The present invention relates to the rail plate technique field, particularly a kind of compound precast concrete track plate.
Background technology
At present, known railway ballastless track plate mainly contains two kinds: a kind of is the post stretching linear pattern pre-track plate of Japan; Another kind is the prefabricated blank flat of pre-tensioning system of Germany, through becoming the track plate behind the precision machine tool polishing plate face.In the railway curve location, the track plate of Japan is that broken line is installed, and regulates the constraint rail through the skew of track plate upper fastener, to reach the purpose that circuit is turned; The track plate of Germany is according to the prefabricated blank of straight line, accomplishes curve type track slab through the polishing of computer control precision machine tool then.
Obviously, the construction regulated quantity is big in the curve location for the track plate of Japan, and needs to add the purpose that the fill-type backing plate reaches adjusting, and cost is high; And the track plate of Germany is higher through precision machine tool polishing cost.Under the plate of the track plate of Japan and the track plate of Germany cement asphalt mortar (being the CA mortar) packed layer is arranged all, this material is the bond of organic matter and inorganic matter, in the construction stage; The CA mortar is by the aluminium powder expansion of getting angry; And environment temperature is very big to the gas forming amount influence, therefore, is difficult to the control expansion rate.In operational phase, its compressive strength, expansion rate, shrinkage factor are to responsive to temperature, and particularly behind the ground generation differential settlement, the long-term vibrating load of train makes the CA mortar fall piece, and is cracked, has a strong impact on durability of structures.For the track plate of Germany, bayonet type vertically connects between plate owing to adopt, and continuous length makes thermal stresses and roadbed generation differential settlement that the plate upper stress is concentrated, and causes the track plate fracture of blockiness, influences durability of structures.
Summary of the invention
Goal of the invention of the present invention is: weak point and endurance issues to existing non-fragment orbit exists provide a kind of compound prestressed concrete railway board.
The technical scheme that the present invention adopts is such: a kind of compound precast concrete track plate; Comprise the track plate with and the support rail platform on top; Said track plate middle part is provided with the self-compacting concrete fill orifice that runs through from top to bottom; The bottom is provided with a shaped steel muscle, and door shaped steel muscle embeds the self-compacting concrete layer that is fixedly connected with track plate bottom, and track plate two ends are provided with pre-buried shear plate respectively.
Setting through door shaped steel muscle and self-compacting concrete layer; Form composite construction; Become the composite orbit plate, be equivalent to increase indirectly structural thickness, all be better than Japanese plate and German plate aspect opposing thermal stresses, the bridge flexural force; And, overcome the problem that the CA mortar shrinks uneven compliance and durability between the plate that brings.
Through pre-buried shear plate being set at track plate two ends; Each track plate is connected successively with screw rod with the shearing junction plate during construction; Make that shearing can well be transmitted between plate; Thereby solve the track irregularity problem that settlement of subgrade causes well, can withstand natural calamities better the influence of track structure.
Said track plate has two kinds of forms, and a kind of is module extender board, and another kind is a curve ruler.During fabrication, high accuracy model capable of using is adjusted rail support groove, thereby produces the track plate that satisfies any sweep needs.
As optimal way, said track plate both sides are provided with the lifting sleeve pipe respectively, and pre-buried insulation sleeve is set on the support rail platform.
As optimal way, said track plate middle part is provided with the hollow frame.Such structure can be practiced thrift track plate manufacturing cost.
Be provided with the cage of reinforcement of forming by transversary reinforcing bar, vertical structure reinforcing bar and handling reinforcement in the said track plate.
In sum; Owing to adopted technique scheme, the invention has the beneficial effects as follows:, form composite construction through the setting of door shaped steel muscle and self-compacting concrete layer; Be equivalent to increase indirectly structural thickness, strengthened ability and the structure durability of resisting thermal stresses, bridge flexural force; Through pre-buried shear plate being set at track plate two ends; Each track plate is connected successively with screw rod with the shearing junction plate during construction; Make that shearing can well be transmitted between plate; Thereby solve the track irregularity problem that settlement of subgrade causes well, can withstand natural calamities better the influence of track structure.
