A kind of race track cornice formwork and supporting method

Abstract

The invention discloses a racetrack cornice formwork and a support method, belonging to the racetrack construction technical field. The racetrack cornice formwork comprises an inner formwork, an outerformwork and a fixing part. The inner formwork can be attached to a leveling pipe connected to the inner cornice of the racetrack skeleton. The outer formwork is arranged on the outer side of the cornice of the racetrack frame. The fixing part is provided with a plurality of groups and spaced apart for fixing the inner formwork and the outer formwork to the cornice of the racetrack frame. The cornice formwork of the racetrack provided by the invention can define the basic contour of the cornice of the racetrack, and by adopting the support method of the cornice formwork of the racetrack, thecornice formwork of the racetrack can be stably supported at the cornice of the racetrack frame, thereby ensuring the pouring quality of the concrete at the cornice of the racetrack and improving theconstruction quality of the cornice of the racetrack.

Description

technical field [0001] The invention relates to the technical field of race track construction, in particular to a race track cornice formwork and a supporting method. Background technique [0002] The construction steps of the track generally include placing the bottom form in the swinging column of the U-shaped groove, placing the built track skeleton on the bottom form, supporting the track cornice formwork outside the cornice of the track skeleton, and the track cornice The formwork is used to define the basic outline of the cornice of the track, and the concrete is sprayed on the track skeleton, and a certain shape of the track is obtained after the concrete solidifies. The skeleton of the track is mainly made of steel bars, and there are refrigeration pipes inside. There are several leveling pipes on the inner surface of the skeleton. The leveling pipes are bound to the refrigeration pipes by iron wires, and are used as a smoothing spray after the concrete spraying is ...

AI Technical Summary

Problems solved by technology

[0003] The track cornice structure is complex and is a hyperboloid structure. Currently, it is difficult to support the track cornice formwork, and the quality of the track cornice formwork support will directly affect the quality of the track cornice concrete pouring. Therefore, it is necessary to find a method that can guarantee Concreting quality track cornice formwork support method is very important
