Embodiment 1

[0059] Example 1: Beam Length Realization Method 1

[0060] The method of realizing the length of the track beam: select prefabricated steel box segments (1) of different lengths + prefabricated connecting plates (2) of different gap lengths to adjust the length of the track beam.

[0061] The method described is applied to straight track beams such as Figure 12 . Linear prefabricated steel box segments such as figure 1 , the linear prefabricated connection plate such as Figure 5 . The length of the prefabricated steel box segment is l si , the number of segments is n; the gap length of the prefabricated connecting plate is Δ pi , then the actual track beam length l ac for:

[0062] l ac = Σ i = 1 n l si + Σ i = 1 ...

Embodiment 2

[0069] Example 2: Implementation Method 2 of Beam Length

[0070] The method of realizing the length of the track beam: select prefabricated steel box segments of different lengths (1) + prefabricated connecting plates of different gap lengths (2) + cast-in-place concrete of different thicknesses (3) to adjust the length of the track beam.

[0071] The method described is applied to straight track beams such as Figure 14 . Linear prefabricated steel box segments such as figure 1 , the linear prefabricated connection plate such as Figure 5 . The length of the prefabricated steel box segment is l si , the number of segments is n; the gap length of the prefabricated connecting plate is Δ pi , the thickness of the cast-in-place concrete at the beam end is Δ ci , then the actual track beam length l ac for:

[0072] l ac = Σ i = 1 n ...

Embodiment 3

[0079] Embodiment 3: Beam height realization method one

[0080] The method of realizing the height of the track beam: select prefabricated steel box segments of different heights (1) + prefabricated metal contact surface structures of different heights (4) to adjust the height of the track beam.

[0081] The method is applied to steel box track beams, such as Figure 16 , Figure 17 .

[0082] The prefabricated steel box segments (1) have different heights, height h si The value range of is 500mm~2000mm; the prefabricated metal contact surface structure (4) has different heights, the height h mi The value range of is 0mm~500mm.

[0083] According to the target beam height, determine the height h of each prefabricated steel box segment si , and then according to the beam height of the track beam to be replaced and the superelevation value of the running surface, the height h of the prefabricated metal contact surface structure is determined by changing the height of the s...

Abstract

The invention relates to a fast production method of track beams and belongs to the technical field of bridge engineering. The production method includes: combining and assembling prefabricated steel box segments (1), prefabricated connecting slabs (2), cast-in-place concrete (3) or prefabricated metal contact surface structures (4), which are designed preliminarily, thus quickly producing track beams which meet the field requirements and which are optional in length, height, curve radius and plane turning angle and optional in wheel-track contact surface linearity and size. The method has the advantages that the track beams different in size and shape can be quickly produced by the production method, and used as the substitute for track beams damaged in operation of straddle monorail transit, or used as a temporary track-beam structure for passage of bridge girder erection machines, on construction sites such as tunnels and deep trenches that a crane approaches with difficulty or at which the crane functions with difficulty during construction of monorail transit systems.

Description

technical field [0001] The invention relates to a rapid manufacturing method of track beams, which can quickly produce track beams with different sizes and shapes. The method is applied to the manufacture of emergency track beams in the emergency repair work of straddle-type monorail traffic track beams, or to the production of temporary track beam structures for bridge erecting machines to pass through during construction. Specifically, this method can be used to quickly produce track beams of any size and shape, which can be used to replace track beams damaged during operation of straddle-type monorail traffic, or when monorail traffic systems encounter tunnels during construction. It is a temporary track beam structure used for bridge erecting machines to pass through construction sites where cranes such as deep trenches and deep trenches are difficult to enter or play a role. Background technique [0002] In the straddle monorail system, the track beam is not only a loa...
