Demolding method and device for end plate of side plate of bilateral pre-tensioned pre-stressed concrete track plate

Abstract

The invention discloses a demolding device for an end plate of a side plate of a bilateral pre-tensioned pre-stressed concrete track plate. The demolding device comprises a side plate demolding device and an end plate demolding device which are used separately or together, and a control system, wherein the side plate demolding device and the end plate demolding device are provided with driving mechanisms which are connected with the control system respectively; and the side plate demolding device and the end plate demolding device work simultaneously or in sequence under the control of the control system, so that the side plate and / or the end plate is separated from the track plate at one time. The invention further relates to a demolding method for the end plate of the side plate of the bilateral pre-tensioned pre-stressed concrete track plate using the demolding device. Preferably, the side plate demolding device and the end plate demolding device are arranged integrally into an integral side plate and end plate demolding device, so that the side plate and the end plate can be separated conveniently and efficiently in sequence or simultaneously. According to the demolding method and the demolding device, the side plate and / or the end plate can be separated conveniently and reliably at one time, so that the appearance of a product is ensured, and the production efficiency is increased.

Description

technical field [0001] The invention relates to a demoulding method and device for a bidirectional pretensioned prestressed concrete track slab side plate end plate, and belongs to the field of manufacturing technology and equipment of high-speed railway ballastless track slabs. Background technique [0002] At present, the high-speed railways in the world mainly use Japanese I-type track slabs and German II-type track slabs. [0003] Japan's I-type track plate is produced by the post-tensioning production process of a single mold. The steel rod is fixed on the side plate by a nut, and the rubber sleeve is used to seal the steel rod and the side plate. The small number of rods and the elasticity of the rubber make it easy to remove the side panels. The defect of this prior art is that: in order to prevent the anchor material from falling off during the service of the track plate, an annular groove is usually engraved on the forming part of the anchor hole on the mold, and a...

AI Technical Summary

Problems solved by technology

The defect of this prior art is that: in order to prevent the anchor material from falling off during the service of the track plate, an annular groove is usually engraved on the forming part of the anchor hole on the mold, and a rubber sealing ring is added to anchor the track plate after demoulding. The hole part leaves an annular groove, but because it is difficult to control the synchronization and levelness during demoulding, it is easy to cause visible micro cracks in the anchor hole part

[0015] However, so far, there is no extensive report on the demoulding technology of the above-mentioned two-way pretensioned prestressed concrete track slab side plate end plate, and there is a need for improvement.
