Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an SR fastener (curtain wall mounting metal fitting) for a building, more specifically, for fixing a floor surface of a skyscraper or the like to a pillar.
The present invention relates to a method for manufacturing a curtain wall fitting.

2. Description of the Related Art In general, it is said that a flexible structure is preferable for a skyscraper as an earthquake countermeasure. Therefore, conventionally, as shown in FIG. 3 which is shown in a vertical section, a curtain wall fitting for fixing the floor surface 5 of the skyscraper and the curtain wall 6 which is a pillar is suitable for a flexible structure. That is, a conventional curtain wall mounting bracket for a super high-rise building has a substantially L-shaped cross section composed of a horizontal portion 1 mounted on the floor surface 5 side of a building and a vertical portion 2 mounted on the curtain wall 6 side of the building. A height adjustment bolt receiver 3 is attached by welding to the upper end of the vertical portion 2 of the metal integrally formed with the parallel to the horizontal portion 1. The horizontal portion 1 has an elongated hole 1a for adjusting the positions of the curtain wall 6 side and the floor surface 5 side and bolting the floor surface 5, and the vertical portion 2 has the elongated hole 1a. Long hole 2a for bolting to the curtain wall 6 side
In addition, the curved wall member 20 having a convex curved surface is welded to the surface in contact with the curtain wall 6 to form a conventional curtain wall mounting bracket for a super high-rise building. Further, an adjustment bracket 6b is welded to the curtain wall bracket 6a attached to the curtain wall 6, and the adjustment bracket 6b is
Height adjustment bolt 6c attached with nuts 6d and 6d
The tip of the abuts on the height adjustment bolt receiver 3.
By adjusting the height adjusting bolt 6c, the height relationship between the floor surface 5 and the curtain wall 6 is adjusted, and the nut 6d
The adjusted height is retained by tightening 6d. The curved surface member 20 of the vertical portion 2 is normally held by being tightened with the bolt 2b and the nut 2c in a state where the highest vertex of the convex curved surface R is in contact with the curtain wall bracket 6a of the curtain wall 6. When a skyscraper sways laterally due to an earthquake or the like, the curtain wall 6 changes from a vertical state to an oblique state flexibly in response to the sway, and the curtain wall bracket 6a attached to the curtain wall 6 has a curved surface R. The curtain wall 6 and the floor surface 5 are connected and held while being in contact with each other as if they were tangents at a position vertically displaced from the highest point of the curtain wall 6. That is, in the event of an earthquake or the like, a flexible structure that flexibly accommodates the change in the curtain wall 6 with respect to the floor surface 5 at an angle other than a right angle due to the curved surface contact is provided so as to avoid damage to the building. Further, the serrated portion 1c near the elongated hole 1a for stabilizing the position of the bolt 1b has conventionally been formed by separately cutting the surface of the horizontal portion 1 of the substantially L-shaped curtain wall fitting.

[0003]

However, according to the above-described conventional example, since the curved surface is formed by welding the curved member 20 to the outside of the vertical portion 2 of the curtain wall mounting member, the product strength is improved. There are problems that not only unevenness occurs, but also it takes time and effort to manufacture, requires a skilled welding engineer, is not suitable for mass production, and the manufacturing cost is high. In addition, the formation of the serrations near the long hole was performed by cutting after the formation of the substantially L-shaped metal piece,
This also has a problem that the cost becomes high. An object of the present invention is to solve such a problem.

[0004]

In order to achieve the above object, the present invention provides the following method for manufacturing a curtain wall fitting. That is, the present invention is a method for manufacturing a curtain wall mounting metal fitting, which is produced by billet-processing a metal material, after heating, and after extruding from the die with an extruder having a die, cooling and commercializing, The die of the extruder has a substantially L-shaped hole shape including a horizontal portion and a vertical portion, and the outside of the substantially L-shaped hole-shaped vertical portion is arcuate. The method for manufacturing a curtain wall mounting member, and the substantially L-shaped hole shape of the die is provided with an uneven serration on an upper surface of a horizontal portion, and a method for manufacturing the curtain wall mounting member according to claim 1. The method for manufacturing a curtain wall mounting member according to claim 1 or 2, wherein the substantially L-shaped hole shape of the die has an eave-shaped protruding portion in parallel with a horizontal portion on an upper portion of a vertical portion. Is.

[0005]

In the above structure, when the outside of the vertical portion of the substantially L-shaped hole is arcuate, the upper surface of the horizontal portion is provided with the serrated portion, and the upper portion of the vertical portion is provided with the eaves-like protrusion, it is billet processed and heated. When an object is extruded from the substantially L-shaped hole shape, the substantially L-shaped thing that comes out of the hole shape has an arc shape outside the vertical portion and a serrated shape on the upper surface of the horizontal portion. The eaves-like protrusion is simultaneously formed on the upper portion of the vertical portion, and has an action of coming out.

FIG. 1 is a schematic explanatory view of an embodiment showing a manufacturing method of the present invention, in which S1 is a billet processing step,
A billet-processed metal material in the billet processing step S1 is heated in the next heating step S2 so as to be easily deformed, and then sent to the extrusion step S3.
Then, the heated billet B is extruded from the die of the die D of the extrusion device C, and cooled in the commercialization step S4 to be commercialized. The method for manufacturing the curtain wall fitting of the present invention is characterized by adopting a specific hole type for the die D, as described later.

FIG. 2 is an explanatory view showing a hole die A of a die D of the extrusion apparatus C. The hole die A is a hole die formed by cutting a horizontal portion 1 and a vertical portion 2 into a substantially L shape. And its abbreviation L
The outer side of the vertical portion 2 having a letter-shape is hollowed out in the shape of an arc 20, and the substantially horizontal portion 1 having an L-shape is provided by hollowing out a notch 1c formed by repeating irregularities on the upper surface side. The notch 1c serves to increase the frictional force and stabilize the position of the tightening bolt. Further, an eaves-like protrusion (height adjusting bolt receiver) 3 is provided in the upper portion of the vertical portion 2 of the substantially L-shaped hole A in parallel with the horizontal portion 1. When the heated billet B (see FIG. 1) is extruded from the hole shape A hollowed out in such an L shape, the billet B follows the hole shape A and has a substantially L-shaped cross section (the serrated portion 1c and the eaves). (Including the projecting portion 3) and emerges in a continuous state. At this time, the outer side of the substantially L-shaped vertical portion is arcuate, the horizontal portion is serrated, and the eave-shaped protruding portion is formed on the upper portion of the vertical portion in parallel with the horizontal portion. The curtain wall mounting bracket is commercialized by cooling this.
