Abstract

(57) [Summary] [Purpose] To prevent the screws from coming out that supplement the joining of the bolts that join the mounting member to the mounted member that has a long hole. [Structure] A mounted member 1 having a long hole 11 formed therein and a mounting member 2 overlapping the same are joined by a bolt 3 and a nut 4 penetrating the long hole 11, and one of the mounted member 1 and the mounting member 2 is joined. At the joint where the screws 5 are screwed from one side to the other to connect them, the head of the bolt 3 on the head side of the screw 5 or the nut 4 has an area that spans all the screws 5, or By disposing a washer 6 having an area that spans all the screws 5 between the head of the screw 5 and the head of the bolt 3 or the nut 4, the head of the screw 5 is restrained in the screwing direction, and the screw 5 is loosened. It is intended to prevent the escape due to.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connecting structure for connecting a mounting member and a mounted member, which joins the mounting member with the mounted member positioned.

[0002]

[Problems to be Solved by Prior Art and Invention]

 When a mounting member that positions a certain member is joined to a mounted member that is a base material and has a long hole by using a bolt, the bolt is fully tightened after the positioning of the mounting member is completed. Since the mounting member and the mounted member are friction-bonded to each other, there is a possibility that the mounting member may move within the long hole due to a load exceeding the frictional force at the portion where the load is received in the direction of the long hole.

Conventionally, the movement of the mounting member is prevented by screwing a screw penetrating both of them into a position where the long hole is removed after the main tightening of the bolt to compensate for the bolt connection, but the screw has a breaking force. Since it is placed under the condition that the screw is loaded, the screw hole easily expands, and there is a danger that the screw will come loose when the screw loosens.

This invention was made by paying attention to the problem at the joint between the mounting member and the member to be mounted, which are positioned by a long hole and bolted together, and an attempt is made to propose a structure for preventing the screw from coming out due to loosening. To do.

[0005]

[Means for Solving the Problems]

 In the present invention, the head area of the bolt or the nut located on the head side of the screw is provided with an area extending over all the screws, or the area extending over the entire head area between the head of the screw and the head of the bolt or the nut. By placing a washer that holds the screw, the screw is restrained from the head side and it prevents the screw from slipping out.

When the head or nut of the bolt is directly adhered to the mounting member or the member to be mounted on the side where the screw is screwed, any one of them straddles all the screws, and when the washer is sandwiched, the washer is Straddle all screws.

The bolt, nut, or washer holds the head of the screw in the screwing direction by the axial force of the bolt, and keeps the screw screwed into both members even if the screw is loosened.

【Example】

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

As shown in FIG. 1 and FIG. 2, the present invention joins a mounted member 1 having a long hole 11 formed therein and a mounting member 2 overlapping the same with a bolt 3 and a nut 4 penetrating the long hole 11, At the joint where the screws 5 are screwed from one side to the other side of the mounted member 1 and the mounting member 2 to connect them, the screw 5 is screwed by the head of the bolt 3, the nut 4, or the washer 6. By restraining in the insertion direction, the loosening of the screw 5 due to the load in the direction of the long hole 11 which the mounting member 2 bears is prevented.

The mounting member 2 is positioned with respect to the member 1 to be mounted by the elongated hole 11 in a state where the bolt 3 is temporarily fixed to the nut 4, and is joined to the member 1 to be mounted by fully tightening the bolt 3. After the members 1 and 2 are joined, the screw 5 is screwed into a screw hole opened through them to supplement the bolt joint.

FIG. 3 shows an attachment member 1 which is a frame member of a curtain wall, and an attachment member which is an edge member 9 for positioning a backing material of the structural adhesive 8 filled on the back surface of the glass 7. 2 shows the joint portion, but in the present invention, the application site is not specified as long as it is the attachment member 2 which is joined to the attached member 1 having the long hole 11 by the bolt 3 and the screw 5.

The screw 5 can be screwed in from either side of the mounting member 2 and the mounted member 1 depending on the site, but as shown in the drawing, the screw 5 is screwed in and the head is located. A washer 6 having an area spanning all the screws 5 is arranged between the mounting member 2 or the mounted member 1 and the head of the bolt 3 or the nut 4, and all the screws 5 are constrained in the screwing direction. When the head of the bolt 3 or the nut 4 directly adheres to the mounting member 2 or the member 1 to be mounted, the head of the bolt 3 or the nut 4 is provided with an area that spans all the screws 5. Bind 5. It suffices if the head of the bolt 3, the nut 4, or the washer 6 that restrains the screw 5 overlaps a part of the head of the screw 5. Alternatively, the screws 5 can be restrained by using bolts 3 and nuts 4 with which washers 6 are integrated.

Since the screw 5 is always screwed into the mounting member 2 and the mounted member 1 by the bolt 3, the nut 4, or the washer 6, the screw hole is enlarged and the shaft is loosened. In the case of slipping out, it is prevented from coming out.

[0014]

[Effect of device]

 The present invention has been described above, and the head of the screw on the head side of the screw or the nut is provided with an area that spans all the screws, or the head of the screw and the head of the bolt or all the screws are placed between the nut. By disposing a washer having an area that spans over the screw head, the head of the screw is restrained in the screw-in direction, so it is possible to prevent the screw from coming off due to loosening.
