Embodiment 1

[0025] The following combination figure 1 And Fig. 2 specifically introduces the steel pipe connector of the railway rail ladder frame sleeper as described in the present invention. figure 1 It is a structural cross-sectional view of a railway rail ladder frame sleeper, which adopts the steel pipe connector according to the present invention, Figure 2(a) and 2(b) Represent the steel pipe connector according to the present invention, wherein, Fig. 2 (a) is a plan view omitting a certain section of its middle part, and Fig. 2 (b) is a front view of the steel pipe connector according to the present invention.

[0026] see Figure 2(a) and 2(b) , the identifier 1 indicates a steel pipe connector made of small-diameter thick-walled steel pipe 6, the two ends of the steel pipe 6 are flattened to form a flattened part 2, and the thickness of the straightened part 2 is 1 / 2 of the height of the outer diameter in the horizontal direction , the outer surface of the middle part of ...

Embodiment 2

[0031] Steel pipe connectors play the role of connecting concrete longitudinal beams and structural constraints in railway rail ladder sleepers. This specification proposes two examples of steel pipe connectors, one adopts a conventional structure and the other is as described in the present invention. Among them, the structural features of conventional steel pipe connectors are as follows: the rib is H-shaped, its thickness is 6 mm, and its width is 30 mm. The material used is ordinary rolled structural steel SS 400 in JIS G3101. The rib is 50 mm The length up to 300 mm is welded to the sides of the two ends of the small-diameter thick-walled steel pipe 6. The outer diameter of the small-diameter thick-walled steel pipe is 76.3 mm, the wall thickness is 9 mm, and the length is 1476 mm. The material used is ordinary carbon in JIS G3444. The pipe material of structural steel STK540; the middle part of the steel pipe connector is coated with a cured rubber coating on the length o...

Abstract

The invention provides a connector constructed 1 made of a steel pipe and bearing a tie function of a ladder-type sleeper for railway tracks, in a connector constructed of a steel pipe 1 used in the ladder-type sleeper for railway tracks integrated with longitudinal beams made of concrete and the connectors constructed of steel pipes 1 by feeding concrete, both end portions of the connector constructed of the steel pipe 1 are flattened in the horizontal direction and a corrosion resistant coating 4 is coated at portions of the connector constructed of the steel pipe 1 exposed to the atmosphere.

Description

technical field [0001] The present invention relates to a connecting piece of a steel pipe structure, which is used in a sleeper in the shape of a ladder frame in a hybrid rigid connection structure (hereinafter referred to as a railway track ladder type sleeper), which is connected to a longitudinal beam made of concrete and The connecting parts of the steel pipe structure are integrated as a railway track laid on the railway bed. Background technique [0002] A railway is a special road consisting of rails and a subgrade supporting the rails. Railway rails include road beds, sleepers and guide rails, while roadbeds include road foundations that support guide rails and rail structures: ballast is usually used as a road bed, and its elastic properties can absorb the impact or vibration caused by train operation. For the railway of ultra-high-speed trains, thick-slab rails with concrete and mortar instead of sleepers and ballast have been adopted in order to reduce the workl...
