Self-supporting semi-dry method prefabricated column connection and construction method thereof

Abstract

The invention discloses a self-supporting semi-dry method prefabricated column connection and a construction method thereof. The connection comprises an upper prefabricated column and a lower prefabricated column, wherein a first reserved hole is formed in the lower end of the upper prefabricated column, a second reserved hole is formed in the upper end of the lower prefabricated column, the firstreserved hole and the second reserved hole are opposite to each other, an enclosed area is used for placing a shear resistant mechanism and pouring mortar, a connecting box and a first longitudinal rib are arranged in the upper prefabricated column, a second longitudinal rib is arranged in the lower prefabricated column, and a top plate and a bottom plate of the connecting box are correspondinglyconnected with the first longitudinal rib and the second longitudinal rib; the construction method comprises the following steps that a, the end head of the first longitudinal rib is screwed into aninner threaded hole; b, the shear resistant mechanism is placed in the first reserved hole and the second reserved hole; c, the second longitudinal rib penetrates through a bottom plate hole and is fixed by a bolt; and d, the mortar is filled through a first reserved hole channel and a second reserved hole channel. According to the self-supporting semi-dry method prefabricated column connection and the construction method thereof, the anti-seismic performance of a prefabricated column connecting node can be basically equivalent to that of a cast-in-place column, a design method of the cast-in-place column can be used continuously, and the engineering design is facilitated.

Description

technical field [0001] The invention relates to the connection of prefabricated reinforced concrete components, in particular to a self-supporting semi-dry prefabricated column connection and a construction method thereof. Background technique [0002] With the transformation and upgrading of the construction industry, prefabricated buildings have attracted more and more attention from the engineering community. As a form of industrialized structure, prefabricated concrete frame structure is widely used in various residential buildings, office buildings and other buildings. For prefabricated concrete frame structures, the connection performance between prefabricated columns plays a vital role in the bearing capacity of the overall structure. [0003] From the perspective of construction methods, the connection between prefabricated columns can be divided into "wet connection" and "dry connection". Among them, the "wet connection" prefabricated column usually has the same c...

Problems solved by technology

Among them, the "wet connection" prefabricated column usually has the same connection performance as the cast-in-place column, but this kind of column connection requires lateral support to fix the column first, and then forms the connection by pouring mortar at the connection part. This connection method often requires A large number of on-site wet operations make it difficult to efficiently utilize the advantages of prefabricated buildings

"Dry connection" usually uses mechanical connection to connect prefabricated columns. This method usually does not require lateral support and has efficient construction performance. However, the connection performance of this method is usually "not equivalent to cast-in-place" and has its own set performance , the corresponding design method is not mature enough
