Embodiment Construction

[0011] The present invention will be further described below in conjunction with the drawings.

[0012] Such as figure 1 Shown is a high-speed rail plate type ballastless track switch plate embedded bolts, including bent steel bolts 4, a casing 1 and a protective cover 2. One end of the casing 1 is connected with a protective cover 2, and the other end of the casing 1 passes through a connecting plate 3. Bending steel bolts 4 are connected, a supporting plate 5 is symmetrically provided on the side of the casing 1, and screw holes 6 are opened on the supporting plate 5. Preferably, the outer surfaces of the bent steel bolts 4, the casing 1, the protective cover 2, the connecting plate 3 and the supporting plate 5 are all provided with an anticorrosive layer; the casing 1 and the protective cover 2, the casing 1 and the connecting plate 3, the connection The connection relationship between the plate 3 and the bending steel bolt 4, the sleeve 1 and the support plate 5 is all weldi...

Abstract

The invention discloses an embedded bolt for a slab type ballastless track turnout of a high-speed railway, and relates to an embedded part. The embedded bolt comprises a bent steel bolt, a sleeve and a protective cover, wherein one end of the sleeve is connected with the protective cover, and the other end of the sleeve is connected with the bent steel bolt through a connecting plate; supporting plates are symmetrically arranged on side surface of the sleeve; and screw holes are formed in the supporting plates. The embedded bolt is higher in accuracy, the fixation strength is increased relatively, and the embedded bolt is not prone to corrosion.

Description

Technical field [0001] The invention relates to a pre-embedded part, in particular to a high-speed rail slab-type ballastless track turnout plate pre-embedded bolt. Background technique [0002] In the construction of high-speed railways, embedded bolts are commonly used connection facilities. The general embedded bolts are fixed by welding and other methods. However, the precision of this kind of embedded bolts is not high, and the most important thing is that the welding points are easily corroded. In addition, the existing embedded bolt structure is relatively simple, the fixing strength is not high, it is easy to loosen, and it is difficult to achieve an effective fixing effect. Summary of the invention [0003] The purpose of the present invention is to provide a high-speed rail slab-type ballastless track turnout plate embedded bolt, which has high precision, relatively increased fixing strength, and is not easy to be corroded. [0004] The technical scheme of the present i...
