Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connection structure of a curtain wall frame material and an attachment, in which an attachment for positioning an edge material is connected to a frame material that supports glass with a structural adhesive.

[0002]

[Problems to be Solved by Prior Art and Invention]

 When the glass of the curtain wall is supported by a frame material such as a frame of a shoji that is stored upright, blind or in the opening, with a structural adhesive filled between the two, it is adhered to the back side of the glass. An edge material serving as a backup material for the agent is arranged.

The edge material is positioned with respect to the frame material of the curtain wall by an attachment that engages with the edge material, and the attachment is supported by the frame material by connecting the attachment to the frame material. It is done by a long hole opened in the prospective direction in the mounting piece that overlaps with the attachment. Therefore, the attachment may move within the long hole due to the wind pressure acting on the glass surface. The movement of the attachment can be prevented by filling the long holes with resin, etc., but this will increase the cost and the number of constructions.

This invention was made by focusing on the problems of the conventional joining method between the attachment and the frame member, and proposes a structure for preventing the attachment from moving without increasing the cost or the number of constructions. Is what you are trying to do.

[0005]

[Means for Solving the Problems]

 In the present invention, a washer having teeth that bite into the attachment piece of the attachment while tightening the bolt is arranged between the head of the bolt that connects the attachment and the frame material, or between the nut and the attachment piece of the attachment. By restraining the attachment, the movement of the attachment with respect to the bolt can be prevented without the need to fill the long holes with resin, and the increase in cost and the number of installations can be suppressed.

The attachment is positioned with respect to the frame material by the long hole formed in the attachment piece, and in that state, the bolt or the nut is tightened to join the frame material, and the teeth of the washer bite into the attachment piece. This stabilizes the displacement due to the force in the expected direction that acts on the attachment.

Since the displacement of the attachment is prevented by the arrangement of the washers, the joining is completed only by tightening the bolt and the nut.

【Example】

 The present invention will be described below with reference to the drawings showing an embodiment.

As shown in FIG. 1, the present invention positions an edge material 6 as a backup material of a structural adhesive 7 filled on the back side of a glass 8 and mounts it on a mounting piece 21 overlapping a frame material 1 of a curtain wall. The attachment 2 having a long hole 211 formed in the prospective direction is joined to the frame member 1 by a bolt 3 and the washer 5 is bitten into the attachment 2 to prevent the attachment 2 from moving with respect to the frame member 1. The frame member 1 includes a frame of a shoji which is housed in an opening surrounded by the vertical and the eyes as shown in the figure and which is a part of the curtain wall in addition to the vertical and the eyesless.

The attachment 2 has a mounting piece 21 that overlaps the prospective piece 11 of the frame member 1 and has a long hole 211 that is long in the prospective direction, and an engaging piece 22 that engages with the edge member 6. Are joined by bolts 3 and nuts 4 which penetrate the long holes 211.

As shown in FIGS. 2 and 3, the washer 5 has teeth 51 that partially protrude on one side, and as shown in FIG. 1, the head of the bolt 3 or the nut 4 and the attachment piece 21 of the attachment 2 are attached. The tooth 51 is arranged facing the mounting piece 21 side between the two, and the tooth 51 bites into the mounting piece 21 of the attachment 2 as the bolt 3 and the nut 4 are tightened, and the tooth 51 is inserted into the projecting piece of the frame material 1. Crimped together with 11 to restrain the movement of Attachment 2. 2 shows the case where the wavy tooth 51 is formed in one direction, and FIG. 3 shows the case where the tooth 51 is formed at the four corners, and both show a square washer 5, but the plane shape of the washer 5 does not matter. .

The washer 5 is made of a material having a hardness higher than that of the attachment 2, such as structural steel or stainless steel, if the attachment 2 is made of aluminum because it is necessary to bite into the mounting piece 21 without the teeth 51 being crushed.

[0013]

[Effect of device]

 The present invention has been described above, and a washer having teeth between the head of a bolt that connects the attachment and the frame member, or between the nut and the attachment piece of the attachment, which has teeth that bite into the attachment piece of the attachment when tightening the bolt. Since the attachments are arranged and the attachments are restrained by washers, the attachments can be prevented from moving with respect to the bolts without the need to fill the resin, and the increase in cost and the number of constructions can be suppressed.
