Embodiment 1

[0024] like figure 1 and figure 2 As shown, the present embodiment provides a supporting device for the cornice formwork under the race track, wherein the lower cornice 20 is located at one end of the race track 10, and the lower cornice formwork supporting device includes a The surface leveling pipe 21, the inner formwork 22, the outer formwork 23 opposite to the inner formwork 22, wherein the upper end of the inner formwork 22 is flat with the concrete design surface at the top of the lower cornice 20, and the lower end of the inner formwork 22 Close to the leveling pipe 21 , and the top of the lower eaves 20 is provided with a plurality of support bars 24 along the surface of the concrete, and the support bars 24 are connected to the outer formwork 23 and the inner formwork 22 .

[0025] The lower eaves formwork support device for the track in this embodiment, wherein the lower eaves 20 is located at one end of the track 10, and the lower eaves formwork support device inc...

Embodiment 2

[0031]This embodiment provides a method for setting up cornice formwork under the track. According to the supporting device for the cornice formwork under the track described in Embodiment 1, supporting the lower cornice of the track includes the following steps: Step S1: The lower eaves 20 of the track are provided with an inner formwork 22, an outer formwork 23 and a leveling pipe 21, and the upper end of the inner formwork 22 is level with the concrete design surface at the top of the lower eaves 20, and the lower end of the inner formwork 22 is Fix on the leveling pipe 21; step S2: arrange a plurality of support strips 24 along the surface of the concrete at the top of the lower cornice 20, and make the support strips 24 and the outer formwork 23 and the inner side Templates 22 are all connected.

[0032] In the method for setting up cornice formwork under the track in this embodiment, in the step S1, the inner formwork 22, the outer formwork 23 and the leveling pipe 21 ar...

Embodiment 3

[0034] This embodiment provides a method for removing the cornice formwork under the track. The supporting device for the cornice formwork under the track described in Embodiment 1 is removed, including the following steps: after the concrete spraying and leveling of the inner surface of the lower cornice 20 are completed, Before the initial setting of the concrete, the support bar 24 and the inner formwork 22 are removed at the same time; the leveling pipe 21 is continuously removed; and the outer formwork 23 is finally removed.

[0035] This embodiment provides a method for removing cornice formwork under the track. Due to formwork support spraying and no formwork support spraying, there will be some staggered platforms on the joint surface, resulting in obvious delamination. Therefore, it is required to carry out the formwork before the initial setting. Dismantling, joint surface treatment in time, to achieve the overall effect, specifically, after concrete spraying and leve...

Abstract

The invention relates to a racing track lower cornice formwork bracing device. A lower cornice is located at one end of a racing track, the racing track lower cornice formwork bracing device comprisesa leveling pipe arranged on the inner surface of the lower cornice, an inner side formwork, an outer side formwork opposite to the inner side formwork, wherein the upper end of the inner side formwork is aligned to a concrete design surface at the top end of the lower cornice. The leveling pipe is attached to the lower end of the inner side formwork, a plurality of supporting strips are arrangedat the top end of the lower cornice along the surface of the concrete, and the supporting strips are connected with the outer side formwork and the inner side formwork. According to the racing track lower cornice formwork bracing device, improvement of the construction efficiency is facilitated, and the acting force influence on the concrete surface is small during subsequent formwork removal.

Description

technical field [0001] The invention relates to the technical field of track construction, in particular to a support device for cornice formwork under 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...
