Assembly node and construction method of prefabricated hollow beam and column

Abstract

An assembling node between a prefabricated hollow beam and a column and a corresponding construction method belong to the construction component technology field. The prefabricated beam appears as a hollow beam (2); a core-through lock (6) connected to a column (3) is embedded inside an inner hole on the hollow beam (2). The method comprises the following steps: A. the hollow beam (2) is arranged on a support frame or a support template; the core-through lock (6) is arranged on the right upper part of the column (3) and the inner hole of the hollow beam (2); and beam ribs (5) at the ends of two opposite hollow beams (2) are welded correspondingly; B. the concrete is cast on the connection part between the column (3) and the hollow beam (2); and the assembling node between the prefabricated hollow beam and the column is formed after the concrete is vibrated and solidified. The definition of 'dark corbel' is adopted by the invention to extend the connection support of the node so as to avoid the superposition between the construction joint and the max shearing-force point of the column and beam structures so as avoid the damage by shear stress. The invention is suitable for the frame-structure buildings and the high buildings.

Description

technical field [0001] The invention relates to a component structure and a construction method of a building assembly frame, in particular to an assembly node and a construction method of a prefabricated hollow beam and column, and belongs to the improvement of a building assembly component and a process method. technical background [0002] At present, the connection method of "steel stool" is adopted for the joints of the assembled structure, that is, a large number of section steel structures are used at the joints, and welding construction is carried out, which is also called dry construction. The disadvantage of dry construction is that the exposed weld seam weakens the original integrity after oxidation, and it is easy to form stress concentration and cause damage. This is the dead spot where the assembly structure is not easy to promote. The traditional assembly structure has limitations in its ability to adapt to architectural design, and lacks the flexibility of ar...

Problems solved by technology

[0004] The first purpose of the present invention is to overcome the time-consuming and material-consuming cast-in-place structure in the prior art, the poor integrity of the assembled structure and the poor adaptability to building changes, and the poor connection rigidity between the beam and the column of the assembled structure. The assembly node of prefabricated hollow beams and columns with high overall rigidity, strong adaptability to architectural changes, and convenient assembly and construction
