Problems solved by technology
However, when the lifting frame drags the enclosure and the formwork slides up, the formwork is subjected to the resistance of the concrete to cause relative displacement and deformation between the enclosure and the enclosure.
With the lifting of the sliding formwork, under the action of the dynamic load and frictional resistance of the vibrating concrete, the lower opening of the formwork is prone to opening, and the phenomenon of concrete leakage and hanging curtains often occurs, which seriously pollutes the visual quality of the silo wall surface
In view of the existing sliding formwork, the appearance quality of the constructed silo cannot meet the quality requirements of fair-faced concrete, and there are often cases of secondary grouting and plastering, which not only increases the project cost, but also fails to achieve the desired quality effect

Abstract
The invention relates to a cylinder silo device with a taper large steel slide template and a production method of the cylinder silo device, which belong to the technical field of the slide template, and a cylinder silo device with a taper large steel slide template which is economical and high efficient and has high product appearance quality and a production method of the cylinder silo device are provided. The invention adopts the technical scheme that: a first inner hoop and a second inner hoop are vertically perpendicular, a first outer hoop and a second outer hoop are vertically perpendicular, the structure of the large steel template is that one side of a steel plate is provided with a plurality of vertical reinforced ribs in a welding way, each reinforced rib is provided with a vertical long edge and a slope long edge, and the vertical edge of the reinforced rib is welded onto the steel plate. The production method of the cylinder silo device with the taper large steel slide template comprises the following steps that: step 1, a hoisting bracket which is shaped like the Chinese character 'kai' is produced; step 2, the hoops are installed; step 3, the large steel template isproduced; and step 4, the large steel template is hung. The cylinder silo device is used for producing the slide template when a wall of the cylinder silo is poured.
Description
technical field [0001] The invention relates to a tapered large-steel sliding formwork device and a manufacturing method thereof, belonging to the technical field of sliding formwork. Background technique [0002] The existing circular silo sliding formwork usually adopts a combination of ordinary small steel molds to hang on the enclosure and slide with the lifting frame, because the circle of the silo is surrounded by n pieces of flat steel molds, theoretically speaking, it is an equilateral n side Therefore, there are obvious vertical rib marks on the concrete surface of the silo that slides out. If there is a torsion deviation, the marks will be more obvious. In addition, the installed formwork of the existing sliding formwork device should have a small upper opening and a large lower opening according to the specification requirements, and the inclination of one side is 0.1%~0.3% of the height of the formwork. The formation of the formwork taper depends on the installat...
