Description

  The present invention relates to a joining structure for fixing a member to be fixed to a fixing member, and more particularly, to a joining structure capable of adjusting an inclination angle and an inclination direction of a member to be fixed with respect to the fixing member.

  When installing a relatively large fixed member such as a photovoltaic power generation panel installation base, a large antenna device, a foundation beam of a building on the ground, a fixing member such as a support pile is erected on the ground, A fixed member is often attached to the upper end portion.

  When placing support piles in harsh construction environments such as steep slopes, hard ground, and many obstacles in the ground, pile errors, twists, and height errors (collectively construction errors) are likely to occur. . Therefore, when a fixed member such as an upper structure is fixed to a fixing member such as a support pile, a joining structure with an adjustment function that can absorb the construction error is required. As this type of joint structure with an adjustment function, for example, there are structures disclosed in Patent Documents 1 and 2.

  The attachment support unit 11 (joint structure) disclosed in Patent Document 1 is mounted by bringing a concave curved surface 38 into surface contact with a receiving seat portion 28U having a ball seat portion 23 and a curved receiving surface 23a of the ball seat portion 23. A mounting base member 30 to which an object is fixed and a fixing bolt 50 for fastening and fixing the mounting base member 30 to the ball seat portion 23 are provided. And the clearance which enables the slide movement of the mounting base member 30 along the curved receiving surface of the ball seat part 23 is ensured in the bolt insertion hole 35 opened in the center part of the concave curved surface of the mounting base member 30. . The mounting base member 30 of the attachment support unit 11 is slidable along the curved receiving surface 23a of the ball seat 23 in a state where it is not fixed to the ball seat 23 of the receiving seat 28U. The direction with respect to the portion 28U can be easily adjusted. In addition, after the mounting base member 30 is bolted to the receiving seat portion 28U, when it is desired to adjust the direction of the mounting base member 30 again, the fixing bolt 50 can be loosened and the readjustment can be easily performed.

  The joint structure 7 disclosed in Patent Document 2 is a structure for connecting the foundation beam 5 and the steel pipe pile 3, and a ball seat head bolt 11 having a convex surface 11 b supported by a pile head cap 19 and a ball seat head bolt. A base beam fixing plate for connecting the other end of the ball head bolt 11 and the base beam 5 to a position adjusting portion 21 (fixing means) for fixing the head 11c, which is one end of the head 11, to the pile head cap 19. 9 and. The position adjusting unit 21 has an insertion hole Ha through which the other end of the ball head bolt 11 is inserted, and the insertion hole Ha has a hole diameter that allows the ball head bolt 11 to swing. Then, when the position adjusting portion 21 comes into contact with the radially extending portion of the ball head bolt 11, the ball head bolt 11 is locked so as not to come out of the insertion hole Ha of the position adjusting portion 21. Therefore, by adjusting the ball head bolt 11 while tilting the ball head bolt 11 in the insertion hole Ha with the convex surface 11b supported by the pile head cap 19 as a fulcrum, the tilt error of the installed state of the foundation beam 5 can be easily adjusted. The foundation beam 5 can be easily connected to the steel pipe pile 3 with high accuracy.

  Here, in the attachment support unit 11 disclosed in Patent Document 1, the fixing bolt 50 is inserted into the bolt insertion hole 35 opened at the center of the concave surface of the mounting base member 30. Therefore, in a state where the attachment is fixed to the attachment base member 30, the head of the fixing bolt 50 may be covered with the attachment, and the readjustment after loosening the fixing bolt 50 becomes impossible. There is a fear.

  Further, in the joint structure 7 disclosed in Patent Document 2, the ball head bolt 11 is swingable with a convex surface 11b formed on the head 11c as a fulcrum. That is, the ball head bolt 11 is in a point contact state with one point support. Further, the protruding side surface of the head 11 c of the ball head bolt 11 comes into contact with the inner peripheral surface of the insertion hole Ha of the position adjustment unit 21, so that the ball head bolt 11 does not come out of the insertion hole Ha of the position adjustment unit 21. It is locked as follows. For this reason, when the tilted ball head bolt 11 is held, the contact area between the side surface of the head 11c of the ball head bolt 11 and the inner peripheral surface of the insertion hole Ha of the position adjusting portion 21 is reduced. It will be held in a point contact state.

  That is, the ball head bolt 11 in the tilted state is in a state where the head 11c is held at a total of three points, one point of the convex portion and two points of the protruding portion. In this state, the holding force is strong in the direction in which the inclination of the ball head bolt 11 is fixed, but the holding force is weakest in the direction perpendicular to the inclination direction, and the holding of the ball head bolt 11 in the inclined state is held. There is a problem that directionality occurs in the strength of power. Further, in the point contact holding, since the load concentrates on the contact point, the contact point is likely to dent for a long term (creep deformation), thereby reducing the contact pressure at the contact point and holding force of the ball head bolt 11. May be damaged in the long term.

  The present invention has been made in view of the above circumstances, and can adjust the tilt angle and tilt direction of the fixed member relative to the fixed member, and can stabilize the fixed member regardless of the tilt angle and tilt direction. It is an object of the present invention to provide a joint structure that can be held and can be easily readjusted in the inclination angle and the inclination direction of the fixed member.

Since the tilt angle and tilt direction of the shaft member with respect to the fixing member can be adjusted, the tilt angle and tilt direction for attaching the fixed member to the fixing member can be adjusted. Further, since it is not necessary to remove the member to be fixed from the joining structure in order to adjust the inclination angle and the inclination direction, the member to be fixed is stably held, and readjustment is easy any number of times.

  According to the said invention (invention 3), since the 1st clamping part and the 2nd clamping part are comprised so that loosening is possible, clamping of the shaft member and to-be-fixed member by a 1st clamping part and a 2nd clamping part Since the state can be released, the male screw member and the female screw member of the shaft member can be relatively rotated without completely removing the member to be fixed from the joining structure. Thereby, only the height of the fixed member relative to the fixing member can be easily finely adjusted / re-adjusted while maintaining the inclination angle and the inclination direction of the shaft member once determined.

  In the said invention (invention 1-3), the said receiving seat part is provided with the receiving member which has said 1st convex curved surface, and the attachment member which attaches this receiving member and connects to the said fixing member, The said receiving member It is preferable that the relative position of the first convex curved surface with respect to the fixing member can be adjusted by changing the position of attachment to the attachment member (Invention 4).

  According to the above invention (Invention 4), in addition to the adjustment of the tilt angle and tilt direction of the fixed member with respect to the fixed member, the fixed member with respect to the fixed member can be simply operated by changing the position where the receiving member is attached to the mounting member. It is possible to easily adjust the plane position.

The round hole 513 of the member 52 is tightened with the bolt and nut 63. This operation is repeated in each support hole 8, and a plurality of vertical bars 91 are mounted in parallel on the support pile 8.

  After the vertical bars 91 are mounted in parallel, a plurality of horizontal bars 92 are arranged in parallel on the vertical bars 91, and the vertical bars 91 and the horizontal bars 92 are fixed by known fixing means such as connecting brackets and screws. Then, the upper structure 9 of the mount for installing the photovoltaic power generation panel is assembled on the support pile 8.

  Here, the position where the pressing member 40 is fastened to the receiving member 11 of the receiving portion 10 is outside the sliding range of the receiving portion contact surface 21 of the bowl-shaped member 20 as shown in FIG. It is in. Thus, even if it is in the state by which the upper structure 9 of the mount for photovoltaic power generation panel installation was mounted on the upper part of the connector 1 by fastening with respect to the receiving member 11 of the receiving part 10 by the pressing member 40 Since the flanged member 20 is slid between the seat 10 and the pressing member 40 by loosening the bolts and nuts 62, the inclination angle and the inclination direction of the shaft member 30 with respect to the support pile 8 can be adjusted. The inclination angle and the inclination direction for attaching the upper structure 9 of the solar power panel installation base to 8 can be adjusted. In order to adjust the tilt angle and the tilt direction, it is not necessary to remove the upper structure 9 of the solar panel installation stand from the connector 1, so that the upper structure 9 of the solar panel installation base is stably held, It is easy to readjust again and again.

  Further, since the first clamping plate member 51 and the second clamping plate member 52 are connected to each other by bolts and nuts 63, the bolts and nuts 63 are loosened to loosen the first clamping plate member 51 and the second clamping plate member 51. The clamping state of the shaft member 30 and the vertical beam 92 by the two clamping plate members 52 can be released. When the clamping state is released in this manner, the male screw member 31 and the female screw member 32 of the shaft member 30 can be rotated relative to each other without completely removing the upper structure 9 of the solar panel mounting base from the connector 1. Only the installation height of the upper structure 9 of the gantry for installing the solar power generation panel with respect to the support pile 8 can be easily readjusted and finely adjusted while maintaining the determined inclination angle and inclination direction.
