Embodiment 1

[0043] Such as Figure 1-4 As shown, a formwork system of a straddle type monorail track beam according to the present invention includes:

[0044] The side form 1 includes a side form panel and a top plate linear adjustment assembly, the side form panel is used for forming the side wall of the track beam, and the top plate linear adjustment assembly is arranged above the inner side of the side form panel for adjusting the top plate in the the alignment of the side-form panels;

[0045] The function of the side form panel is to ensure the geometric dimensions of the track beam section, which is composed of a whole steel plate, and the embedded parts on the track beam are determined according to the final position of the embedded parts to open positioning connection holes on the side form panel; The bottom of the top plate alignment adjustment assembly is a triangular structure. By adjusting the height of the top plate alignment plate, the beam height, vertical curve alignment...

Embodiment 2

[0057] Such as Figure 1-4 As shown, the method for using a formwork system of a straddle-type monorail track beam according to the present invention, applying the formwork system of a straddle-type monorail track beam as described in Embodiment 1, comprises the following steps:

[0058] A. Set the bottom form force mechanism 4 at the position to be poured, the bottom form force mechanism 4 is connected to the bottom form 3, adjust the bottom form force mechanism 4 so that the bottom form 3 forms the shape of the designed track beam bottom ;

[0059] B. Control the driving assembly 51 to drive the mobile platform 5 to move along the track 6 to the position to be poured;

[0060] C. Adjust the position of each traversing assembly 22 in the chute according to the design of the track beam and fix it, then adjust all the traversing assemblies 22 to pull and compress the side mold 1, and constrain the side mold 1 to form the required shape , all the traversing components 22 synch...

Abstract

The invention discloses a straddle type single-rail track beam formwork system and an application method. The formwork system comprises side molds, side mold stress application mechanisms, a bottom mold, a bottom mold stress application mechanism, a movable platform, tracks and supporting mechanisms. By application of the formwork system, the distribution position of each transverse movement assembly relative to the corresponding side mold can be independently adjusted, then, accurate adjustment of the side mold stress application positions can be achieved, and accordingly it is ensured that the side mold line shapes can meet the forming requirements of complex section space composite curve as well as straight line and curve transition section track beams. After track beam pouring and initial setting, the side mold stress application mechanisms drive the side molds for demoulding, the movable platform drives the side mold stress application mechanisms and the side molds to move to thenext pouring position, the initially-set track beams can be stored and completely cured and formed on the site, and the problems about potential safety hazards and quality of lateral overturning and cracking during track beam movement due to movement after initial setting like an existing manner are solved. The formwork system is simple in structure, convenient to use, high in mold reversing efficiency and capable of saving time.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a formwork system and a using method of a straddle-type monorail track beam. Background technique [0002] Straddle-type monorail traffic is a new type of traffic system that has emerged in recent years. Vehicles, track beams and turnouts are its three key technologies. Vehicles ride directly on the slender track beams, and the track beams have dual functions of load bearing and guidance. , the line is mainly arranged in the central divider of the road and the side of the existing road, and flexibly shuttles through the city in the form of a viaduct span. The straddle-type monorail traffic has been favored by the society because of its strong climbing ability, small turning radius and low construction cost. It is widely favored and will definitely become an important direction for the development of urban rail transit in the future; the track beam is the key to the straddle-typ...
