The construction plan of reinforcing the balcony railing with secondary structure reinforcement

The secondary structure does not include balcony railings, only balconies and wall columns.

Most of the cantilever beams on the first floor of the balcony are "stranded"! The lower part of the cantilever beam is not equipped with stressed steel bars, and "stranded" means that the end of the cantilever beam is on the outdoor ground, and the cantilever beam becomes a simply supported beam, and the lower part of the simply supported beam is bound to crack if there is not enough steel bar. It should be disconnected from the outdoor ground to form a suspension.

First. The concrete mix is incorrect, resulting in insufficient strength. >>>More

Hello, whether there is a waterstop under the exterior wall of the balcony of the secondary structure of the building. Some non-load-bearing masonry, structural columns, lintels and other parts that need to be completed before decoration in frame, shear wall and frame shear engineering are called secondary structures. The process time of the secondary structure is constructed after the completion of the construction of the primary structure (referring to the load-bearing member part of the main structure), which is relative to the load-bearing structure, and is a non-load-bearing structure, and the maintenance structure, such as structural columns, ring beams, water-stopping anti-beams, parapet walls, roof-pressing walls, infill walls, partition walls, etc.

There is no problem with the second gluing.

However, in general, an anti-mold sealant is used. >>>More
