Abstract

The invention relates to a large steel formwork integrated with a reserved box and its construction method, which relates to the technical field of building construction and is used to solve the problem that the traditional corbel reserved box positioning deviation affects the climbing of the steel platform formwork. Both sides of the reserved box are longitudinally provided with oblong holes; the formwork components include a pair of formwork bodies and angle steel longitudinal ribs. Connecting holes matching the oblong holes are set vertically at a certain interval on the side, so that several reserved boxes are sandwiched between the two formwork bodies at equal intervals and fixed to form a whole large steel formwork. This design allows construction personnel to operate outside the large steel formwork, which solves the manual operation problems of installing, dismounting and moving the reserved box. Moreover, the reserved box is connected with the side bolts of the formwork body, which avoids the problem that the concrete slurry contaminates the bolt holes. The most important thing is that it will not affect the quality of the surface after the concrete is formed.

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 corbel reserved box is often temporarily tied at the corresponding elevation of the vertical steel bar, and the positioning is not firm enough. In the subsequent process of formwork installation and concrete pouring, the reserved box is easily displaced, which will lead to concrete pouring. The positioning size of the reserved hole formed later is deviated. When the steel platform formwork climbs to the corbel extending out to the corresponding height, due to the positional deviation of the hole, some corbels cannot accurately reach the reserved hole, so that the climbing action of the steel platform formwork cannot be completed smoothly. SUMMARY OF THE INVENTION [0003] Aiming at the problem of the pos...
