Method for building vault lining of flue

Abstract

The invention discloses a method for building a vault lining of a flue. The method comprises the following steps of: during building a fire-proof vault lining of a coke oven flue (1) by using fire-proof bricks (2), supporting and moving a mould (3) for building a vault by using a movable operating platform and mould support integrated bracket so as to facilitate the construction of constructors on an operating platform of the bracket, and laying a fire-proof material on the operating platform at the same time. Because a mould adjustment support is arranged on the upper part of the movable bracket, the elevation control of the mould is simple; because the movable bracket adopts truckles and the lower part of the movable bracket is provided with a bracket adjustment support, the operating platform is convenient to move and has stronger bearing capacity; the operating platform and the movable bracket which are convenient to move are adopted so as to meet the construction requirement and reasonably allocate the labor force; and the movable bracket has a simple structure, is made of a common material, has the characteristics of economy, practicability and simple and convenient operation, and is easy to popularize.

Description

technical field [0001] The invention relates to a flue, in particular to a method for building the inner lining of the flue vault by using a mobile operating platform and a mold support integrated bracket. Background technique [0002] When the flue is closed (the concrete pouring of the flue vault is completed), the construction of the vault is limited by the construction process of refractory bricks and doors. The construction sequence from the middle to both sides also requires several months of construction time. The support of the mold often depends on the method of reserving corbels four floors away from the arch foot on the flue wall, with a distance of 1500mm as the bearing point. The upper four layers of bricks press the corbels, and two layers of standard bricks are laid flat on the corbels. , place horizontal square wood on the bricks so that the mold can be supported on it. The length of the mold is 700mm, of which 100mm is the part that overlaps with the vault a...

AI Technical Summary

Problems solved by technology

Refractory materials need to be placed on the operating table of the construction workers. The self-weight of the working platform with a considerable bearing capacity requires 8 people to move freely. In this way, the construction distance is 600mm each time, and 8 people are needed, and there is a phenomenon of idle work.
