One-pile-one-column connecting structure adopting reverse building method and construction method of one-pile-one-column connecting structure

Abstract

The invention relates to the field of building construction, in particular to a reverse construction method one-pile one-column connecting structure which comprises a steel pipe column casing and a steel rib column arranged at the upper end of the steel pipe column casing, a connecting assembly is arranged between the steel pipe column casing and the steel rib column, and the connecting assembly comprises a first connecting plate fixed in the steel pipe column casing and a second connecting plate fixed on the steel rib column. The invention discloses a construction method for one-pile-one-column connection through a reverse building method. The construction method comprises the steps that S1, coordinates of a constructed steel pipe column casing are measured; s2, a post-cast strip space of at least 300 centimeters is reserved in the steel pipe column casing; s3, the steel reinforced column is hoisted, the first connecting plate is inserted into the steel pipe column cylinder, then the position of the steel pipe column is rechecked on site and is checked with the position of the drawing, and the position of the steel reinforced column is properly adjusted according to the deviation condition; s4, the two semicircular plates are installed at a cylinder opening of the steel pipe column cylinder; and S5, concrete is poured into the post-cast strip space reserved in the steel pipe column casing. The connecting structure has the effect of improving the structural strength of the one-pile-one-column connecting joint.

Description

Technical field [0001] The present application relates to the field of building construction, in particular, involving a column, a column, a column, and a construction method thereof. Background technique [0002] At present, in the process of construction of the foundation pit, a column is a permanent structure, which is the main vertical force component. The general construction process of the reverse approach is first, one column, and then opened the first floor of the foundation pit. When the first board is under construction, the upper steel structure is connected to the lower column, and then the basement is ligated. Summer plate steel and pouring concrete. After the first floor of the basement is completed, the next layer of earth-mounted dark digging, at which time the upper steel structure can be lifted synchronously. [0003] The advantage of reverse construction is the effectively controlling the influence of the foundation pit on the surrounding environment. Since the...

Problems solved by technology

The verticality control of one column and one pile is one of the key technologies in the reverse construction method. Due to excessive measurement and setting-out errors, construction process, geological conditions and other reasons, there will often be a certain deviation in the position of one column and one pile constructed in advance. As a result, the lower inserted columns of the upper steel structure cannot be concentric with one column and one pile, resulting in eccentric force on one column and one pile, which directly affects the quality of the project and the safety of the structure
