Embodiment Construction

[0035] Hereinafter, a preferred embodiment of the present invention will be described in detail by referring to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations will be omitted when it may indeed obscure the subject matter of the present invention.

[0036] Figures 3 to 9 is a schematic side view showing the connection structure of the bracket 1 and the peripheral column 20 . In the present invention, a displacement receiving device is provided at the junction of the bracket 1 and the peripheral column 20 , ie, between the end 2 of the bracket 1 and the upper and lower brackets 21 integrally connected with the peripheral column 20 . This displacement receiving device contracts or extends according to the displacement of the end 2 of the support 1, so that it automatically absorbs the displacement between the end 2 of the support 1 and the upper and lower brackets 21 of the peripheral...

Abstract

Disclosed is a novel connection structure of an outrigger and a perimeter column. The connection structure has a function of automatically absorbing differential column shortening which is occurred between the core wall and the perimeter column during or after the construction of a building, thereby preventing excessive stress due to the differential column shortening. In addition, the invented apparatus also functions as damper by providing additional damping to the structure to resist dynamic loading such as wind and earthquake efficiently.

Description

[0001] Cross References to Related Applications [0002] This application claims the full rights of Korean Patent Application No. 2007-27568 filed on March 21, 2007 at the Korean Intellectual Property Office and Korean Patent Application No. 2007-122864 filed on November 29, 2007, The above application documents are hereby incorporated by reference. field of invention [0003] The present invention relates to a novel connection structure and corresponding device for connecting brackets and peripheral columns. The present invention will automatically absorb the difference in column shrinkage between the core wall and the perimeter columns without creating additional stresses in the building volume and resist lateral loads like wind or earthquakes with the additional damping provided by this arrangement. Background technique [0004] Typically, cores are provided in tall buildings to support lateral loads, such as wind and / or earthquakes, as well as additional vertical loads....
