A construction method for sealing a hole with a combination of profiled steel beams and profiled steel plates

Abstract

The invention relates to a construction method for sealing a hole by the combination of profiled bar beams and profiled steel sheets. The construction method is characterized in that connecting boltsare arranged in concrete columns and floor slabs around the hole; a self-supporting lifting platform is arranged at the position of the hole, and a jacking device is arranged on a platform expansion plate of the self-supporting lifting platform; after the profiled bar beams and the profiled steel sheets are jacked to the set height, the profiled bar beams, reinforcing angle steel I and reinforcingangle steel II are separately connected with the connecting bolts, and flat steel placement grooves are connected with the two ends of flat steel; the profiled steel sheets and reinforcement cages are sequentially arranged on the upper portions of the profiled bar beams and the flat steel; after connecting tenons, steel bar connecting sections, and angle steel connecting bars with the reinforcement cages are firmly connected, first concrete I in the middle part of baffles is poured, and then concrete II at the edges of the baffles after the concrete I finally solidifies; and finally, the construction of a fiber grating layer, an anti-cracking mortar layer and a leveling mortar layer is carried out in sequence. According to the construction method for sealing the hole by the combination ofthe profiled bar beams and the profiled steel sheets, the construction efficiency and quality of hole sealing can be improved, and cracks of the plate surface are prevented.

Description

technical field [0001] The invention relates to a construction method for a floor opening, in particular to a construction method for sealing an opening by combining a shaped steel beam and a profiled steel plate, which belongs to the field of decoration engineering and is suitable for the opening sealing project adjacent to a wall column. Background technique [0002] With the development of my country's economy, the construction industry is also constantly innovating and developing. During the construction of modern high-rise residential engineering structures, there are more and more structural transformations due to incomplete consideration in the early stage or professional installation needs. After the main structure of the construction project is completed, it is often necessary to seal the original opening. In the process of sealing slab construction, how to complete the structural slab sealing operation quickly, efficiently and with controllable quality has become a...
