Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a device for mounting a curtain wall on a building main material.

"Prior Art" Conventionally, a metal fitting to be attached to a building main material is one in which a mounting bolt provided on an outer wall material is securely tightened with a nut to the above-mentioned main material. Therefore, when the expansion and contraction of the outer wall material after the construction and the inward and outward warping phenomenon, the load is remarkably concentrated on the connecting portion between the mounting bolt and the outer wall material, which increases the risk.

"Problems to be solved by the invention" The present invention is a curtain wall capable of releasing a load based on the tilting of the mounting bolt caused by the sliding and warping of the mounting bolt caused by the expansion and contraction of the outer wall material and absorbing the tilt error. The purpose is to obtain a mounting device.

"Means for solving the problem" This proposal is to make a large diameter notch for inserting the mounting bolt in the mounting bracket,
A nut having a concave spherical surface in contact with an outer surface of the large-diameter cutout, the outer surface of the small-diameter hole of the washer bulging into a spherical surface, and a concave spherical surface in contact with the bulged spherical surface is provided. It is composed of a curtain wall mounting device formed so as to be screwed into a bolt.

"Operation" Therefore, the mounting metal fitting 1 is fastened to the building main material 7 with the bolt 8, and the outer wall material 9 of the outer wall material 9 is fixed in a state where the washers 4 and 4 are in contact with the outer side surfaces 1'and 1'of the large diameter cutout 2 of the metal fitting 1. When the mounting bolt 10 projecting on the back surface is inserted into the large-diameter notch 2 through the small-diameter holes 3 and 3, and in that state, the nuts 6 and 6 screwed into the bolt 10 are rotated and propelled in the opposite direction. The washers 4, 4 are pressed against the outer side surfaces 1 ′, 1 ′ of the large-diameter cutout 2 via the bulging spherical surfaces 5, 5 so that the outer wall member 9 can be attached to the main member 7. In this state, when the outer wall material 9 expands and contracts in the vertical and horizontal directions due to changes in the outside air temperature, the mounting bolt 10 slides in that direction, but the load causes the washers 4 and 4 to move to the outer surface 1'of the large-diameter notch 2,
Slide along 1 '. Further, when the outer wall member 9 is inwardly and outwardly warped and tilted due to the temperature change caused by the irradiation of sunlight on a part of the outer wall member 9, the mounting bolt 10 tilts (FIG. 2). By this tilting, the bolt 10 tilts together with the nuts 6, 6. At this time, the concave spherical surfaces 6'of the nuts 6, 6 are bulged spherical surfaces 5,
Rotate along 5. In addition, bolt 10 and mounting bracket 1 when mounting
Even if there is an error in the angle between and, the error is absorbed.

[Example] An L-shaped mounting bracket 1 is fastened to a building main material 7 made of H-shaped steel with bolts 8. The mounting bracket 1 supports the outer wall material 9, and also has a large diameter notch 2 (also the large diameter hole 2 shown in FIGS. 1 and 2) through which a mounting bolt 10 protruding from the back surface of the outer wall material 9 is inserted. There is no problem). A set of washers 4 and 4 is disposed in contact with both outer side surfaces 1'and 1'of the large-diameter cutout 2, and the washers 4 and 4 each have a small-diameter hole 3 into which the bolt 10 is inserted.
Is to be drilled. On the outer surfaces of the washers 4 and 4, tightening nuts 6 and 6 to be screwed into the bolt 10 are arranged. The outer surfaces of the washers 4 and 4 are formed into a bulging spherical surface 5, and the inner surfaces of the nuts 6 and 6 are formed into a concave spherical surface 6'which abuts the spherical surface 5, and a large-diameter cutout 2 is formed as shown in FIG. Also, by inserting the mounting bolt 10 into the small diameter holes 3 and 3 and propelling the nuts 6 and 6 in opposite directions to hold both outer side surfaces 1 ′ and 1 ′ of the large diameter cutout 2 with the washers 4 and 4, the outer wall. Material 9 is the main material 7
To be attached to. The base of the mounting bolt 10 is the outer wall material 9
The outer wall member 9 and the mounting bolt 10 are integrally fixed to each other by being fixed by being buried in the outer wall member 9 or by being screwed into a cap nut fixed by being buried in the outer wall member 9. The sliding member 11 may be held between the abutting surface and the contact surface. In the above-described embodiment, the mounting bracket 1 is held between the two
This is an example of a set, but if the force applied to the bolt 10 is limited to one direction, one set on one side may be used.

"Effect" Since the present invention is configured as described above, the mounting bolt 10 slides and tilts as the outer wall member 9 slides and tilts due to the expansion and contraction of the outer wall member 9 to allow the outer wall member 9 to respond to the above sliding and tilting. The material 9 can be made to respond to changes in the outside air temperature, the danger due to separation and separation of the outer wall material 9 can be prevented, and safety can be improved.
