Description

Technical Field

[0001] The utility model relates to the technical field of building structures, and particularly relates to a prefabricated structure for column construction without formwork. Background Technique

[0002] A construction column refers to a reinforced concrete construction column that should be set in the walls of multi-story brick-concrete structure buildings in order to enhance the integrity and stability of the building, and is connected to the ring beams of each floor to form a spatial frame that can resist bending and shear. It is an effective measure to prevent the collapse of the house. The installation positions of the construction columns are at the four corners of the exterior wall, the intersection of the transverse wall and the exterior longitudinal wall at the staggered floor position, both sides of the larger opening, the intersection of the inner and outer walls of the large room, etc. In addition, the requirements for the installation of construction columns vary depending on the number of floors of the house and the seismic intensity. The minimum cross-sectional size of the construction column is 240mm×180mm, the vertical steel bars are mostly 4φ12, the stirrup spacing is not greater than 250mm, and the cross-section and steel grade of the construction columns at the four corners of the building can be appropriately increased with the increase of the seismic intensity and the number of floors.

[0003] For traditional construction columns, generally after the wall masonry is completed, wooden formwork is supported, and processes such as formwork preparation, formwork support, fixation, and formwork removal are required. This process has a long construction period, many processes, and the fixation between the formworks requires bolts, which increases the loss of human and material resources.
