Background

The self-compacting concrete layer plays a key role in bearing up and down and transferring longitudinal, transverse and vertical loads from an upper track structure as an important structural component of the CRTS III type plate ballastless track structure, and the success or failure of the CRTS III type plate ballastless track structure is determined by the construction quality of the self-compacting concrete layer. In the current self-compaction concrete construction process, self-compaction concrete layer sets up between track board and base, need carry out spacing banding to self-compaction concrete filling layer periphery in pouring the shaping in-process, also guarantee the discharge of air in the self-compaction concrete, still need exert decurrent pressure to self-compaction concrete filling layer in the track board top simultaneously, prevent track board come-up and skew or fine tuning back cause track board position change because of the reason that the people trampled when pouring self-compaction concrete, and in the current construction process, if not take measures, cause track board come-up and track board and self-compaction concrete layer crack phenomenon, can bring very big harm for the construction.

Aluminium alloy track board closing device among the prior art has light in weight, corrosion-resistant, the outward appearance roughness is good, bearing capacity advantage such as big, but, along with the development of the track traffic of china, use in not only the high-speed railway construction, also will use in the subway, consequently face the problem that can not adapt to in the use, the problem of existence mainly has: firstly, the original design is integrated, so that the installation is inconvenient, and the width is unchanged, so that the self-compacting concrete layer can not adapt to the compaction of self-compacting concrete layers with two widths of high-speed rails and subways; and secondly, the edge sealing template is fixed, so that the edge sealing template cannot be tightly propped against the side of the self-compacting concrete layer with a certain inclination. The sealing edge template is difficult to fasten when facing a large area, and the problem of unbalanced pressure of each point is often caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a detachable and adjustable track slab pressing device which can adapt to both high-speed rail and subway and has balanced pressure on each point of an edge sealing template.

The purpose of the utility model is realized as follows: a detachable and adjustable track slab pressing device for high-speed railways and subways comprises supporting legs, a pressing bar, an upper bolt group and side bolt groups, wherein the supporting legs and the pressing bar are connected into a door-shaped structure; the tightening bolt foot comprises square foot, ball joint, screw rod, nut and lock nut, and ball joint, screw rod and nut structure as an organic whole, and square foot is the components of a whole that can function independently structure, and inside is the sacculus hole and is used for being connected with the cooperation of ball joint, and lock nut is used for locking the screw rod on the side fixed plate after ball joint and screw rod are tight with the banding template top.

The object of the utility model can be achieved by: the landing leg comprises the landing leg body, strengthening rib and connecting plate, and landing leg body top sets up the connecting plate, and the connecting plate lower part sets up the strengthening rib, and landing leg body lower part is equipped with the mounting hole and is used for connecting the side fixed plate, is equipped with the mounting hole on the connecting plate and is used for connecting the pressure thick stick.

The lower part of the supporting leg body is provided with a plurality of groups of mounting holes for adjusting and connecting different heights of the lateral fixing plates on the supporting leg body.

The material is aluminum alloy number 6061, the alloy state: t6.

The material is carbon steel or stainless steel.

The utility model has the following positive beneficial effects: the self-compacting concrete layer compaction method is suitable for compacting self-compacting concrete layers with various widths such as high-speed rails, subways and the like; and secondly, for the edge sealing template with a large area, balanced pressure can be applied to the edge sealing template through the tightening bolt feet of each point position, and meanwhile, the pressing of the edge sealing template with a certain inclination can be adapted.
