Abstract

The invention discloses an integral construction method for assembling a prefabricated column pier and a post-cast strip-shaped foundation beam, comprising a prefabricated column pier and a post-cast strip-shaped foundation beam. The first joint steel bar of the force steel bar, the second joint steel bar and the third joint steel bar extending from the side of the prefabricated column pier for connecting the longitudinal stress steel bar of the post-casting strip-shaped foundation beam rib beam and the distribution steel bar of the wing plate; The prefabricated column pier is placed at the predetermined column position, the extension of the first steel bar joint and the frame structure construction of the first structural layer are carried out, and the second joint steel bar and the third joint steel bar of the prefabricated column pier are timely and synchronously constructed during the superstructure construction. After extending and pouring the concrete, the strip-shaped foundation beam is poured and the structure is further extended upward; the present invention uses the post-cast strip-shaped foundation beam to form a cross-strip foundation with high spatial rigidity and bear the self-weight and construction load of the continuously extending upward structure, thereby To achieve the purpose of saving time.

Description

Technical field

[0001] The present invention relates to the field of building construction, in particular suitable for a prefabricated column pier and a post-cast strip foundation beam assembly integral construction method for unattended basements. Background

[0002] A bar foundation under a column is a reinforced concrete strip foundation arranged in one or both directions, also known as a beam foundation or foundation beam. Its cross-section consists of a ribbed beam and a wing plate that extends horizontally outward. Because the ribbed beam beam height is relatively large and a certain number of longitudinal stress reinforcement bars and stirrups are configured, and the bottom of the wing plate is provided with transverse bending reinforcement and wing plate distribution steel reinforcement, it has a large shear, bending and impact cutting ability, so it is often used in the case of large load and small bearing capacity of the foundation, such as the frame or row frame struct...
