Steel large formwork integrally designed with reserved boxes and construction method of steel large formwork

Abstract

The invention discloses a steel large formwork integrally designed with reserved boxes and a construction method of the steel large formwork, relates to the technical field of building construction, and is used for solving the problem that the positioning deviation of traditional bracket reserved boxes affects the climbing of a steel platform formwork. Long round holes are longitudinally formed inthe two sides of the reserved box; a formwork component comprises a pair of formwork bodies and angle steel longitudinal ribs; long strip holes are longitudinally formed in the positions, corresponding to brackets, of the formwork bodies; the angle steel longitudinal ribs are arranged at the two sides of the long strip holes; and connecting holes matched with the long round holes are vertically formed in the side edges of the angle steel longitudinal ribs at certain intervals, so that the plurality of reserved boxes are clamped between the two formwork bodies at equal intervals, and the wholesteel large formwork is fixedly formed. Due to the design, a constructor can operate on the outer side of the steel large formwork, and the manual operation problems of mounting, dismounting and position moving of the reserved boxed are well solved; in addition, the reserved boxes are in bolt connection with the side surfaces of the formwork bodies, so that the problem that concrete slurry pollutes bolt holes is avoided; and most importantly, the quality of the formed concrete surface is not affected.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a large steel formwork designed integrally with a reserved box and a construction method thereof. Background technique [0002] In the existing construction, the reserved box of the corbel is often temporarily tied at the corresponding elevation of the vertical steel bar, and the positioning is not firm enough. During the subsequent formwork installation and pouring of concrete, the reserved box is easily displaced, which will lead to the pouring of concrete The positioning size of the reserved hole formed later produces a deviation. When the steel platform formwork climbs to the corresponding height of the extended corbel, some corbels cannot accurately reach the reserved hole due to the position deviation of the hole, so that the climbing action of the steel platform formwork cannot be completed smoothly.
