JPH04366255A - Connecting structure for steel-reinforced curtain wall member - Google Patents

Abstract

PURPOSE:To simplify structure of a curtain wall by a method wherein a fixing part is made by providing a fixing flange to the front of a steel reinforcing material so that it projects frontward and a connecting hardware therefor is made adjustable within the horizontal and the vertical planes, and a mullion is connected thereto for covering the said fixing part. CONSTITUTION:A fixing flange 2-1 is welded vertically to the front of a vertical steel reinforcing material 1 so that it projects frontward, and long nuts 3 are welded to the upper and the lower parts of the said fixing flange 2-1. A box-shaped connecting hardware 4 is put over the fixing flange 2-1 and is fixed thereto by screwing bolts 6 penetrating through loose holes on the upper and the lower sides of the connecting hardware 4 down to the upper and the lower long nuts 3. Then a channel-shaped base 7 of a mullion A of the steel reinforcing material 1 is fitted to the connecting hardware 4, covering its fixing part T, and side faces of both the connecting hardware 4 and the channel-shaped base 7 are placed in superposition and are fixed together with bolts 8 and nuts 9. In another instance, a loose hole 11 is provided to a fixing flange 2-2 of the steel reinforcing material 1, and a connecting hardware 14 is fixed to the fixing flange 2-2 with nuts screwed down to the outer periphery of a long nut 12 that is provided, penetrating through the abovementioned loose hole. Then the channel-shaped base 7 is fitted and is fixed with bolts 15 to cover the above-mentioned structure.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall mullion member connection structure reinforced with steel frames.

0002

[Problem to be solved by the invention] When installing a curtain wall on the wall of a building with a large floor height such as an atrium, it is difficult to support it with mullions alone, and it is necessary to install steel reinforcing materials such as steel columns on the inside of the curtain wall. It was requested that the steel reinforcing material and the mullions be connected with fasteners and the curtain wall be reinforced with the steel reinforcing material. It is conceivable to use ordinary angular hardware as the fastener, but it is not desirable for these fasteners to be visible on the outside, and a simple structure that is easy to work on site is desired.

The present invention was developed in view of the above circumstances.

0004

[Means for Solving the Problems] The present invention provides a member connection structure for a steel reinforced curtain wall, in which a mounting flange is provided protruding from the front surface of the steel reinforcing member, and connecting fittings are attached to the mounting flange in horizontal and vertical planes. The mounting portion is adjustable and is fixed by covering the mounting portion with a mullion placed on the front side of the steel reinforcing member.

[0005]

[Embodiment] In the embodiment shown in FIG. 1, the steel reinforcing members 1 assembled vertically and horizontally are made of H-shaped steel, and an I-shaped mounting flange 2-1 is vertically attached to the front surface of the vertical steel reinforcing members 1. They are welded and protruded at appropriate intervals, and long nuts 3 are welded to the top and bottom of this mounting flange 2-1. A box-shaped connecting fitting 4 is mounted on a mounting flange 2-1, and bolts 6 passing through loose holes 5 on the upper and lower sides of the box-shaped connecting fitting 4 are screwed into vertical long nuts 3 and fixed.

The groove-shaped base 7 of the mullion A placed on the front side of the steel reinforcing member 1 is fitted over the mounting portion T, and the box-shaped connecting fittings 4 and both sides of the groove-shaped base 7 are overlapped and bolted. 8. Nut 9
It is fixed at Note that the screw 10 is used to further secure the position after the installation adjustment.

In the embodiment shown in FIG.
The front mounting flange 2-2 has a loose hole 11, a long nut 12 is provided passing through the loose hole 11, and a groove-shaped connecting fitting 14 is connected by a nut 13 screwed onto the outer periphery of the long nut 12. The mounting portions T are fixed to both sides of the mounting flange 2-2 in a back-to-back manner, and the groove-shaped base 7 of the mullion A is provided.
is fitted over the mounting portion T, and both side surfaces of the grooved base 7 are overlapped with the end surfaces of the long nut 12 and fixed with bolts 15.

An overall view of a curtain wall implementing the above invention is shown in FIG.

[0009]

Effects of the Invention The present invention has the above-described structure, and most of the connecting members, ie, fasteners, between the mullions or blinds of the curtain wall and the steel reinforcing members are accommodated in the base grooves of the mullions or blinds, and bolts and nuts are It looks good as only a part of the curtain wall is visible on the outside, and it is easy to adjust the installation of each member of the curtain wall, and the structure is relatively simple, improving workability on site.
