Intensified reinforced concrete sewer pipe steel mold

Abstract

The invention discloses an intensified reinforced concrete sewer pipe steel mold which comprises an upper cylinder, a lower cylinder, a mounting hole, a first supporting flange, a second supporting flange and a third supporting flange. The lower end of the upper cylinder is provided with the lower cylinder, a steel cylinder is arranged inside the upper cylinder, the mounting hole is formed insidethe steel cylinder, the first supporting flange is arranged outside the upper cylinder, one side of the first supporting flange is provided with the second supporting flange, one side of the second supporting flange is provided with the third supporting flange, and a reinforcing cross bar is arranged on the front side of the upper cylinder. The intensified reinforced concrete sewer pipe steel moldhas the beneficial effect that the steel cylinder with the diameter smaller than the diameter of the reinforced concrete sewer pipe steel mold is additionally arranged, so that the inner wall pressure area of a pipe body is larger, rolled concrete is more uniform and dense, the inner wall is more smooth, the concrete slump is reduced, the dead time can be shortened, the production efficiency is improved, the production quality is also ensured, and the structure is simple.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a reinforced concrete drainage pipe steel mold. Background technique [0002] The cement pipe mold is the main equipment for the production of cement pipes. It is a steel container for constraining concrete and forming cement pipes. It uses the rotation of the roller shaft and the steel mold to generate pressure and centrifugal force to make the material densely formed. The formed product is formed by steam or natural curing. The pipe reaches the standard strength. The cement pipe mold can be divided into two types according to the connection mode of the formed drainage pipe, rigid interface and flexible interface. According to the cement pipe production process, it can be divided into centrifugal pipe mold and suspension roller pipe mold. The interface form of the pipe can be divided into flat type, tongue and groove type, socket type and steel tongue and groove type. The pr...

According to the cement pipe production process, it can be divided into centrifugal pipe mold and suspension roller pipe mold. The interface form of the pipe can be divided into flat type, tongue and groove type, socket type and steel tongue and groove type. The production of reinforced concrete drainage pipes formed by traditional suspension rollers is to pour dry hard concrete. Its own weight is formed by centrifugal rolling of the suspension roller shaft, which has the characteristics of high requirements for concrete slump, and is prone to uneven rolling concrete, which affects production quality
