A unitized curtain wall column hook connection structure

Abstract

A unitized curtain wall stand column hook connection structure comprises a first stand column and a second stand column, wherein an insertion plate and a slot which are corresponding to each other are respectively arranged between the first stand column and the second stand column, the tail end of the insertion plate is in overhead hook shape, a lock plate is arranged in the slot, the lock plate and the insertion plate are oppositely arranged, and a hook which is corresponding to the overhead-hook-shaped tail end of the insertion plate and can be interlocked with the overhead-hook-shaped tail end of the insertion plate is arranged at the tail end of the lock plate. The unitized curtain wall stand column hook connection structure can guarantee stability of the stand columns through interlocking of the overhead hook and the hook after the stand columns are connected in butt joint mode, prevents a bending instability performance from occurring, and accordingly improves overall structural strength of a curtain wall. Furthermore, under the same conditions, the unitized curtain wall stand column hook connection structure enables the section of a sectional material to be simple, optimizes the section of the sectional material, saves material cost, and simultaneously decreases the number of manufacturing procedures, and improves processing efficiency.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a hook connection structure for a unit curtain wall column. Background technique [0002] A curtain wall is a continuous enclosure system suspended from the main structure of a building. At present, there are two types of curtain walls widely used in the market: frame curtain wall and unit curtain wall. Among them, the unitized curtain wall is a curtain wall system formed by connecting multiple adjacent unit components and installing them on the periphery of the building. The unit assembly is composed of butt-joint keels and panels installed on it, which are assembled in the factory and then transported to the construction site for butt-joint installation. Such as figure 1 , figure 2 As shown, the existing unitized curtain wall keel 1' and keel 2' are not connected and fixed after being plugged in. In order to meet the force requirements, the curtain wall keel 1' and keel ...

AI Technical Summary

Problems solved by technology

figure 1 and figure 2 The practice will inevitably increase the section of the keel of the curtain wall and increase the cost. Secondly, because the keel 1' and keel 2' of the curtain wall are still separated, the optimal distance (12mm) at the rear end of the keel will increase or decrease when the glass panel bears a positive load. , resulting in the instability of the keel

In addition, when the wind load is too large, the opening column is prone to "open mouth" deformation, and it is more prone to bending and twisting instability.
