Embodiment

[0026] Such as Figure 1 to Figure 9 As shown, a two-way pretensioned prestressed concrete track slab mold includes: track slab bottom mold 1, rail bearing platform 2, load-bearing side mold 3, load-bearing end mold 4, tension plate 5, pressure plate 6, Prestressed steel bar hole 7, lifting sleeve hole 8, track plate bottom mold support steel plate 9, tension connecting rod 10, tension locking wedge 11, pretensioning balance force bar 12, model positioning hole 13, sliding wheel 14 and Perfusion hole mold 15.

[0027] There are 18 rail bearing grooves 1-1 evenly distributed on the bottom mold 1 of the track slab, arranged in parallel in pairs and arranged in two rows.

[0028] The 18 rail-supporting platforms 2 are firstly cast and then precision-machined, and are evenly distributed and embedded in the rail-supporting grooves 1-1. The rail support platform 2 has: a pre-embedded casing positioning pin 2-1.

[0029] There are two groups of embedded casing positioning pins 2-1...

Abstract

The invention provides a prestressed concrete rail board die manufactured through a bidirectional pre-tensioning method. The prestressed concrete rail board die is characterized by comprising a rail board bottom die, rail bearing tables, force bearing side dies, force bearing end dies, force plates, prestressed rebar holes, a plurality of tensioning connecting rods, and a plurality of tensioning force locking wedge blocks, wherein rail bearing grooves are uniformly distributed in the rail board bottom die; the rail bearing tables are uniformly distributed and are embedded in the rail bearing grooves; the force bearing side dies are symmetrically arranged on the two sides of the rail board bottom die; the force bearing end dies are symmetrically arranged on the other two sides of the rail board bottom die; the force plates are arranged on the force bearing side dies and the force bearing end dies; the prestressed rebar holes are distributed in the force bearing side dies and the force bearing end dies; the plurality of tensioning connecting rods are inserted on the two sides of the force bearing side dies and the two sides of the force bearing end dies; the plurality of tensioning force locking wedge blocks and the tensioning connecting rods are in one-to-one correspondence; and one of the tensioning force locking wedge blocks is fixed to the force bearing side dies, and the other of the tensioning force locking wedge blocks is inserted into the connecting rods.

Description

technical field [0001] The invention relates to track slab mold technology, in particular to a two-way pretensioned prestressed concrete track slab mold. Background technique [0002] At present, there are two types of track slabs known in the field of rail transit technology: prestressed structure and non-prestressed structure. Prestressed structures are subdivided into post-tensioned prestressed structures and pre-tensioned prestressed structures. The pre-tensioned structure is further divided into a one-way pre-tensioned structure and a two-way pre-tensioned structure. According to the production method of the track slab, it is the fixed platform method, that is, the track slab model is fixed and installed in the workshop at a certain distance, and other operating procedures are carried out successively according to the position of the model. The production method of the fixed model is inefficient, the material flows in the workshop, and it takes up a lot of space. Co...
