Heating furnace upright post cofferdam internal mold and making method thereof

Abstract

The invention discloses a heating furnace upright post cofferdam internal mold. The cofferdam internal mold is axially provided with a through hole through which a movable upright post passes, and the cofferdam internal mold comprises a pair of cofferdam internal mold members in a size which is half of the cofferdam internal mold. The cofferdam internal mold is characterized in that: the cofferdam internal mold members are made of expanded polystyrene. A making method of the heating furnace upright post cofferdam internal mold comprises the following steps of: 1) making a pair of sample plates in a size which is half of the section of the cofferdam internal mold; 2) making an expanded polystyrene board into a preformed block, the height of which is equal to that of the cofferdam internal mold and the section of which is greater than or equal to half of the section of the cofferdam internal mold; and 3) tidily putting the pair of sample plates made in the step 1) on two sections of the preformed block in parallel, cutting the preformed block along the outlines of the pair of sample plates to obtain the cofferdam internal mold members in a size which is half of the cofferdam internal mold, and thus forming the heating furnace upright post cofferdam internal mold by using the pair of cofferdam internal mold members. The cofferdam internal mold is convenient and fast for supporting, simple in making and low in cost.

Description

technical field [0001] The invention belongs to the field of moulds, and in particular relates to an inner mold of a heating furnace column embankment and a manufacturing method thereof. Background technique [0002] In the construction of the walking heating furnace, the inner mold of the embankment needs to be supported at the lower part of each movable column, and the quality of its support will directly affect the movement stroke of the movable column. Currently used dike internal formwork is divided into steel formwork and wood formwork. [0003] The steel formwork is composed of a pair of steel modules whose size is one-half of the internal formwork of the embankment. Since the thickness of the steel formwork is 55mm, and the gap between the movable column and the inner wall of the embankment is only 60mm, the ordinary steel formwork is connected here. The "U" type buckle used cannot be installed, and a pair of steel modules can only be connected by bolts. The use of...

AI Technical Summary

Problems solved by technology

Because the structure is not convenient for bolt connection, the strength of the wooden formwork is not strong. During the use, there are often problems such as wrong platform of the poured finished product, deviation of the gap between the movable column and the inner wall of the embankment, etc.; , the dismantling operation will be carried out slightly in advance. Too early will affect the quality of the poured finished product. If the time is too late, it can only be destructively dismantled. After the wooden formwork is abolished, it will become a large amount of construction waste

After the internal mold of the embankment is removed, once construction waste falls into the water seal groove at the lower part of the embankment during the subsequent construction of the heating furnace roof, a lot of cleaning work will be added, affecting the entire construction period
