Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall connecting structure between a prefabricated scaffold provided outside a curtain wall and a curtain wall in a curtain wall construction method for building construction.

[0002]

2. Description of the Related Art In a curtain wall construction method for building construction, an assembly type scaffold is often provided outside the curtain wall. FIG. 6 is a partial front view of a building showing an example of a curtain wall, 1 is a vertical direction mullion (also referred to as a cube), 2 is a horizontal blind eye, 3 is glass, and F is a building frame. In this case, it is the floor slab. Use the fasteners (not shown) to build the Marion 1 body F
Then, the seamless member 2 is attached to the mullion 1 using an attaching member to form a frame body, and the glass 3 is inserted and fixed in the frame body.

When there is a work to be performed from the outside of the building, such as assembling the frame, inserting the glass, applying a pushing edge between the frame and the glass or applying a sealing material, finishing the exterior, etc., it is assembled on the outside of the curtain wall. A ceremony scaffold must be provided. FIG. 7 is a partial side view of the prefabricated scaffold and a part of the building seen from the horizontal direction, where S is the prefabricated scaffold, C is the curtain wall, and 6 is the prefabricated scaffold S and the curtain wall C are connected in the horizontal direction. It is a tie material.

There are log scaffolds, steel pipe-type assembled scaffolds, frame scaffolds using a steel pipe gate formwork called a building frame, etc., but in any case, the thickness is independent compared to the height. Wall, occupational health and safety regulations (eg 5th
Article 70 “Steel pipe scaffolding”, Paragraph 3), etc., obliges to provide “wall joints or retainers” with a predetermined interval and strength in the vertical and horizontal directions to prevent falling.

The retainer is a diagonal member that supports the fall of the scaffold from the outside, but it is not effective because it is ineffective unless it is supported from a considerably distant position outside, and if the scaffold wall becomes taller. Since it requires a considerably long member and cannot be adopted in a normal building construction site, it is common to provide a wall joint. However, due to the exterior appearance of the building, there are often no protrusions or the like for fixing the connecting material on the outer surface of the curtain wall C, so it is necessary to drill holes in the exterior material of the curtain wall, the mullion, or the frame part such as the eyes, or to install nuts. It is common practice to weld such a female threaded member as described above and screw in a bolt-shaped connecting material, but not only must these troublesome operations such as drilling and nut welding be performed, but also scaffolding Block these holes after dismantling,
It is necessary to remove the nuts, and if they are incomplete, there are problems such as rainwater entering and impairing the appearance of the building.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a horizontal cross-sectional view showing the mullion 1, the joining material attachment hardware 5 of the present invention, and the joining material 6 in a separated state. The connecting material mounting hardware 5 of the present invention includes an I-shaped member 51 in which one side of a quadrangular overlapping portion 512 is bent at a right angle to form a locking claw 511, and one side of a quadrangular overlapping portion 522 is bent at a right angle. To form a mounting surface 523, the tip of the mounting surface 523 is bent at a right angle in the opposite direction, and further bent at the right angle in the same direction to form an engaging claw 521, and the I-shaped member 51 and the L-shaped member 52. A fixing means 53 for fixing the overlapping portions 512 and 522 of the member 52 by overlapping them and a mounting surface 523 of the L-shaped member.
And a receiving nut 55 to which the bolt-shaped connecting member 6 is screwed.

On the outer surface of the mounting surface 523 of the L-shaped member 52,
A nut groove 524 formed by a pair of claw-shaped ribs is provided,
The receiving nut 55 is inserted and held in this. To prevent the receiving nut 55 from falling, screws may be attached to the upper and lower sides or the lower side of the nut groove 524 or putty-like padding may be used. In this embodiment, since the I-shaped member 51 and the L-shaped member 52 both have the uniform cross section shown in FIG. 1 in the height direction, they can be easily manufactured, for example, by cutting an aluminum extrusion mold material. it can.

Generally, the outer surface side of the mullion 1 is formed into an H shape by forming a groove into which glass is inserted on both sides. Therefore, the outer flange 11 of this H shape portion is used to mount the L shape member 52 on the mounting surface. The inner surface of 523 is pressed against the outer flange 11 of the mullion 1, and the fixing means 53 fixes the I-shaped member 51 and the L-shaped member 52.
The locking claws 511 and 521 of the
The fitting 5 for attaching the connecting material is fixed to the mullion 1 by sandwiching.

The mounting procedure will be described with reference to FIG. 1. First, as shown by the arrow, the mounting surface 52 of the L-shaped member 52 is shown.
3 is applied to the outer flange 11 of the mullion 1, and the overlapping portion 512 of the I-shaped member 51 is overlapped with the overlapping portion 522 of the L-shaped member 52 as shown by the arrow. Since the overlapping portions 512 and 522 are provided with bolt holes, a bolt is inserted into the overlapping portions 512 and 522 as fixing means 53 as shown by an arrow, and a nut 53a is tightened as shown by an arrow to form an I-shaped member 51. The locking claws 511 and 521 with the L-shaped member 52 are brought close to each other, so that the connecting material mounting hardware 5 is fixed to the mullion 1. By loosening the nut 53a, the mounting position in the height direction can be adjusted arbitrarily. Moreover, it is easy to remove after use and no traces remain, so there is no risk of rainwater invading or spoiling the appearance of the building.

When the scaffold is assembled on the outside of the curtain wall, the connecting material 6 such as a steel rod provided with a screw as shown by the arrow is screwed into the nut 55 to complete a wall connecting structure having a predetermined strength. . I-shaped member 51 and L
As the fixing means 53 for the mold member 52, in addition to bolts, clamps,
There are various things such as welding and rivets. FIG. 2 shows a partial horizontal cross-sectional view of the curtain wall in a state in which the connecting material mounting hardware 5 is fixed to the mullion 1, and FIG. 3 shows a partial vertical cross-sectional view taken along the line AA in FIG. 41 is a pushing edge, 42
Is a fixing material, and 43 is a sealing material (these are collectively referred to as the fixing member 4).

FIG. 4 is a perspective view showing a case in which a steel plate is bent to manufacture a connecting material mounting hardware 5 having substantially the same shape as that shown in FIG. 1 as a second embodiment. The difference is that the nut groove 524 is not provided and the receiving nut 55
Is welded and attached directly to the attachment surface 523 of the L-shaped member 52. Since the L-shaped member 52 is made of a steel plate, the steel receiving nut 55 can be welded.

FIG. 5 is a perspective view showing a connecting material mounting hardware 5 which is a modified example of the second embodiment. The difference from FIG. 4 is that the bent portion for the locking claw 521 of the L-shaped member 52 is different. Extend it to the outdoor side as it is, and attach the upper and lower surfaces of the mounting surface 523 to the rib 525.
The point is that it is folded and box-shaped. As a result, it is possible to prevent the edge of the glass from being caught by the tie material fitting 5 when the glass is fitted.
