Problems solved by technology

[0003] In addition, at the corner of the building structure that bears a large load, the traditional rectangular column has a small section moment of inertia, which reduces the torsional ability of the component to resist earthquake action, while increasing the cross-sectional area of ​​the rectangular column causes convex corners inside the building, affecting the building. The internal use area and equipment layout, and the proposal of special-shaped columns is an effective way to solve the above problems

Embodiment Construction

[0044] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] A multi-limb L-shaped special-shaped column with a built-in core column that can recover functions, such as figure 1 As shown, it includes a rectangular parallelepiped central side column 1, and a corner of the central side column 1 is provided with a bidirectional core column 2 in parallel, and the bidirectional core column 2 leans against the central side column 1; figure 2 As shown, one top of the bidirectional stem 2 expands outward in a conical shape, the other top of the bidirectional stem 2 decreases inward in a conical shape, and the inclination angles at both ends of the bidirectional stem 2 are not greater than the friction angle; the upper end surface of the bidirectional stem 2 is provided with an L-shaped first groove, and both ends of the first groove extend to the edge of the bidirectional stem;

Abstract

The invention discloses a function recoverable multi-limb special L-shaped column with built-in core columns. The column comprises a bidirectional core column in an L shape and two unidirectional corecolumns. A center side column and side columns fit to the outer walls of the bidirectional core column and two unidirectional side columns. Steel beams, diagonal web members and replaceable members are connected between any two adjacent side columns. The invention also discloses an assembling method of the multi-limb special L-shaped column. The method comprises: bidirectional core column, centerside column and side column installation, connector installation, unidirectional core column and side column installation, connector installation and replaceable member installation. The multi-limb special L-shaped column is used at the corner of a building, can quickly replace the replaceable member with energy failure after strong earthquake action, and can quickly restore the structural function. The method is easy to implement and is convenient for industrial use in batch.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and relates to a multi-leg L-shaped special-shaped column with a built-in core column and a recoverable function. The invention also relates to an assembly method of the multi-leg L-shaped special-shaped column. Background technique [0002] As the main load-bearing member, the column bears the force transmitted by the beam and transmits the force to the foundation. However, the damage caused by earthquakes to building structures is complex. The damage to columns after strong earthquakes is difficult to repair, which in turn makes it difficult to guarantee structural safety or restore structural functions. Therefore, it is necessary to propose a new frame column design concept, which is convenient for construction and safe, so as to ensure that the structure will not be damaged under frequent earthquakes, or to quickly restore structural functions after strong earthquakes by only r...
