Embodiment 1

[0025] Such as figure 1 and figure 2 As shown, the present embodiment provides a supporting device for cornice formwork on the track, wherein the upper cornice 30 is located at one end of the track 10, and the upper cornice formwork supporting device includes an inner surface of the upper cornice 30 The leveling pipe 31, the inner formwork 32, and the outer formwork 33 opposite to the inner formwork 32, wherein the upper end of the inner formwork 32 is flat with the concrete design surface at the top of the upper cornice 30, and the lower end of the inner formwork 32 is pasted Close to the leveling pipe 31 , the top of the upper cornice 30 is provided with a plurality of support strips 34 along the surface of the concrete, and the support strips 34 are connected to the inner formwork 32 and the outer formwork 33 .

[0026] The cornice formwork supporting device on the track in this embodiment, wherein the upper cornice 30 is located at one end of the track 10, and the upper ...

Embodiment 2

[0032]This embodiment provides a method for supporting cornice formwork on a race track. According to the cornice formwork support device on a race track described in Embodiment 1, the upper cornice of the race track is supported, including the following steps: Step S1: along the The upper eaves 30 of the race track are arranged with an inner formwork 32, an outer formwork 33 and a leveling pipe 31, and the upper end of the inner formwork 32 is level with the concrete design surface at the top of the upper eaves 30, and the lower end of the inner formwork 32 is fixed on On the leveling pipe 31; step S2: laying a plurality of support strips 34 along the surface of the concrete on the top of the upper cornice 30, and connecting the support strips 34 to the inner formwork 32 and the outer formwork 34 .

[0033] The cornice formwork support method on the racetrack described in this embodiment, in the step S1, the inner formwork 32, the outer formwork 33 and the leveling pipe 31 ar...

Embodiment 3

[0035] This embodiment provides a method for dismantling cornice formwork on a track. The cornice formwork supporting device on a track described in Embodiment 1 is removed, including the following steps: Before the initial setting, remove the support bar 34 first; continue to remove the inner formwork 32, and then remove the leveling pipe 31 after the inner formwork 32 is dismantled; finally remove the outer formwork 33.

[0036] This embodiment provides a method for removing cornice formwork on the track. Due to formwork support spraying and formwork support spraying, there will be some staggered platforms on the joint surface, resulting in obvious delamination. Therefore, it is required to remove the formwork before initial setting , carry out the joint surface treatment in time to achieve the overall effect, specifically, after the concrete spraying and leveling of the inner surface of the upper cornice 30 are completed, before the initial setting of the concrete, the suppo...

Abstract

The present invention relates to a cornice formwork support device, a support method and a removal method on a track, wherein the upper cornice is located at one end of the track, and the upper cornice formwork support device includes an inner surface of the upper cornice Leveling tube, inner formwork, and outer formwork opposite to the inner formwork, wherein the upper end of the inner formwork is level with the concrete design surface at the top of the upper cornice, the lower end of the inner formwork is close to the leveling pipe, the The top of the upper cornice is provided with a plurality of support strips along the surface of the concrete, and the support strips are connected to both the inner formwork and the outer formwork. The invention is beneficial to improve the construction efficiency, and has the least influence on the force of the concrete surface when the formwork is subsequently removed.

Description

technical field [0001] The invention relates to the technical field of track construction, in particular to a support device for cornice formwork on a track, and a support and removal method. Background technique [0002] The 24th Winter Olympic Games will be held in Beijing in 2022. Beijing will host all ice events, while Yanqing and Zhangjiakou will host all snow events. In order to ensure the smooth progress of the Winter Olympics, the relevant competition venues are also under construction. [0003] Both bobsleigh and sled events are highly ornamental snow sports. The bobsleigh and sled track, as the competition slides for the snowmobile and sled events of the Winter Olympics, is a slide with high quality requirements. Since this track is the first in China and the third in Asia, it is the most difficult and complex facility to design in the Beijing Winter Olympics. [0004] Since the snowmobile and sled track is a space-changing hyperboloid track with complex shape, t...
