Description

  The present invention provides the first plate-like member and the second plate-like member with a connecting portion that can be connected via a bolt and a nut, respectively. The present invention relates to a fixture for other objects in which a bolt insertion hole is formed in each of two plate-like members.

Conventionally, in order to connect the first plate-like member and the second plate-like member by the connecting portion, a bolt is inserted between the bolt insertion holes, and the first plate-like member and the second plate are tightened by tightening the bolt. The opposing surfaces of the shaped member are brought into pressure contact with each other.
However, there is a possibility that the first plate-like member and the second plate-like member may be relatively displaced due to an external force, load, vibration, or the like.
Therefore, in order to prevent relative displacement between the first plate-like member and the second plate-like member, the first plate-like member and the second plate-like shape are provided at the periphery of the bolt insertion hole. It is conceivable to employ a structure (for example, refer to Patent Document 1) in which concave and convex portions that can be engaged with each other are formed on the opposing surfaces of the members.

  However, when the above-described structure is adopted, the unevenness formed on the facing surfaces of the first plate member and the second plate member until the bolt insertion holes provided on the first plate member and the second plate member are aligned with each other. There is a problem that it takes time to relatively adjust the position of the first plate-like member and the second plate-like member smoothly because the portions are caught with each other.

  Accordingly, when connecting the first plate member and the second plate member, the first plate member and the second plate member can be adjusted after the alignment while the bolt insertion holes can be adjusted smoothly. Is to stably maintain the relative connection position.

  The first characteristic configuration of the present invention includes a base-side support member having a first fixing portion to the floor at a lower end portion, and an other object support member having a second fixing portion for fixing a fixing target member to the upper end portion. The first connection part is configured by providing a first connection part that can be connected via a bolt to the upper end part of the base support member and the lower end part of the other object support member. However, a bolt insertion hole is provided in each of the peripheral side plate of the base support member and the peripheral plate of the other object support member, and one of the bolt insertion holes is formed as a long hole, One of the long hole-shaped bolt insertion holes is formed by forming a flat side plate on which one of the bolt insertion holes is formed, providing a recess in a peripheral portion of the other bolt insertion hole, and tightening the bolt and the nut. The bolt is used to press and deform the peripheral side plate formed along the recess. Than the washer between the insertion is to flat washer and the circumferential side plate have configured deformed pressurizing provided small-diameter pressure auxiliary washer.

  According to the first characteristic configuration of the present invention, the peripheral side plates are relatively positioned along one bolt insertion hole formed in the long hole in a state where the bolt is inserted through the bolt insertion hole of each peripheral side plate. While the bolt and the nut are tightened, one bolt is applied to the recess formed in the peripheral portion of the other bolt insertion hole by the deforming and pressing portion provided between the opposing surface portions of the bolt and the nut. It can prevent that the peripheral part of an insertion hole deform | transforms and raise | generates the relative position shift of peripheral side plates.
