Description

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

  When installing a relatively large fixed member such as a solar panel installation rack, a large antenna device, or 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 thereof.

  When placing support piles in a severe construction environment such as steep slopes, hard ground, or many underground obstacles, it is easy for piles to fall, get twisted and have height errors (collectively construction errors) . Therefore, when fixing fixed members, such as a top structure, to fixed members, such as a support pile, the connection structure with the adjustment function which can absorb the said construction error is required. Examples of such a joint structure with adjustment function include the structures disclosed in Patent Documents 1 and 2.

  The attachment support unit 11 (joining structure) disclosed in Patent Document 1 mounts the receiving seat 28U having the ball seat 23 and the concave receiving surface 23a on the curved receiving surface 23a of the ball seat 23 so as to attach it. It has a mounting base member 30 to which an object is fixed, and a fixing bolt 50 for clamping and fixing the mounting base member 30 to the ball seat 23. And, in the bolt insertion hole 35 opened in the central part of the concave curved surface of the mounting base member 30, a clearance which enables the sliding movement of the mounting base member 30 along the curved receiving surface of the ball seat 23 is secured. . The mounting base member 30 of the mounting support unit 11 can slide 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 orientation with respect to the unit 28U can be easily adjusted. In addition, after the mounting base member 30 is bolted to the receiving seat portion 28U, if it is desired to adjust the direction of the mounting base member 30 again, it can be easily readjusted by loosening the fixing bolt 50.

  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 includes a spherical head bolt 11 having a convex surface 11 b supported by a pile head cap 19 and a spherical head bolt. Position adjustment portion 21 (fixing means) for fixing the head 11c which is one end of the head 11 to the pile head cap 19 and a foundation beam fixing plate for connecting the other end of the ball head bolt 11 and the foundation beam 5 And nine. The position adjustment portion 21 has an insertion hole Ha through which the other end of the ball-seat bolt 11 is inserted, and the insertion hole Ha has a hole diameter in which the ball-seat bolt 11 can swing. Then, when the position adjusting portion 21 abuts on 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, the inclination error of the installation state of the foundation beam 5 can be easily adjusted by adjusting the ball seat head bolt 11 while tilting it in the insertion hole Ha with the convex surface 11b supported by the pile head cap 19 as a fulcrum. The foundation beam 5 can be easily connected to the steel pipe pile 3 with high accuracy.

  Here, in the mounted object support unit 11 disclosed in Patent Document 1, the fixing bolt 50 is inserted into the bolt insertion hole 35 opened in the central portion of the concave surface of the mounting base member 30. Therefore, in the state where the attachment is fixed to the mounting base member 30, the head of the fixing bolt 50 may be covered by the attachment, and the adjustment can not be performed by loosening the fixing bolt 50. There is a risk.

  Further, in the joint structure 7 disclosed in Patent Document 2, the spherical head bolt 11 is swingable with a convex surface 11b formed on the head portion 11c as a fulcrum. That is, the ball head bolt 11 is in a point contact state of one point support. Further, the projecting side surface of the head portion 11 c of the ball head bolt 11 abuts on the inner circumferential surface of the insertion hole Ha of the position adjustment portion 21, whereby the ball head bolt 11 does not come out of the insertion hole Ha of the position adjustment portion 21. To be locked. For this reason, when holding the ball head bolt 11 in the inclined state, the contact area between the side surface of the head 11 c of the ball head bolt 11 and the inner peripheral surface of the insertion hole Ha of the position adjustment portion 21 decreases. It will be held in the state of point contact.

  That is, in the inclined state, the head 11c is held at a total of three points, that is, one point of the convex portion and two points of the overhang 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 orthogonal to the inclination direction, and the ball head 11 in the inclined state is held. There is a problem that directionality arises in the strength of force. In addition, in holding point contact, the load is concentrated on the contact point, so the contact point tends to be dented in a long time (creep deformation), thereby reducing the contact pressure of the contact point and holding force of the ball head bolt 11 May be lost in the long run.

  The present invention has been made in view of the above circumstances, and is capable of adjusting the inclination angle and inclination direction of the fixed member with respect to the fixing member, and stabilizing the fixed member regardless of the inclination angle and inclination direction It is an object of the present invention to provide a joint structure which can be held and which can be easily readjusted for the tilt angle and tilt direction of the fixed member.

  In order to achieve the above object, firstly, the present invention has a receiving seat portion having a first convex curved surface and connected to a fixing member, and a first concave which can slide in surface contact with the first convex curved surface.

The present invention provides a bonding structure (invention 1).

  According to the above invention (Invention 1), the joining structure is achieved because the position at which the pressing member is fastened to the receiving seat portion or the fixing member is outside the sliding range of the first concave surface of the bowl-like member. Even when the fixed member is placed on the upper part of the case, the pressing member slides between the receiving seat and the pressing member by loosening the fastening means for fastening the receiving seat or the fixing member. Since the inclination angle and the inclination direction of the shaft member with respect to the fixing member can be adjusted, the inclination angle and the inclination direction in which the fixing member is attached to the fixing member can be adjusted. In addition, since it is not necessary to remove the fixed member from the joint structure in order to adjust the tilt angle and the tilt direction, the fixed member is stably held, and readjustment is easy any number of times.

  In the above invention (Invention 1), the shaft member has a structure in which a male screw member having a male screw formed on the outer periphery and a female screw member having a female screw formed on the inner periphery are screwed together. It is preferable that the axial length of the shaft member can be adjusted by relatively rotating the female screw member (Invention 2).

  According to the above invention (Invention 2), in addition to the adjustment of the inclination angle and inclination direction of the fixed member relative to the fixed member, the fixed member relative to the fixed member only by a simple operation of relatively rotating the male screw member and the female screw member Adjustment of the height can also be easily performed.

  In the above invention (Invention 2), the shaft member and the member to be fixed are further sandwiched by the first holding portion and the second holding portion, and the device further comprises a holding member connecting the shaft member to the member to be fixed. It is preferable that the first holding portion and the second holding portion be configured to be freely tightened (invention 3).

  According to the above invention (Invention 3), the first holding portion and the second holding portion are configured to be freely tightened, so that holding of the shaft member and the fixed member by the first holding portion and the second holding portion Since the state can be released, relative rotation of the male screw member and the female screw member of the shaft member becomes possible without completely removing the fixed member from the joint structure. As a result, it is possible to easily finely adjust and re-adjust only the height of the fixing member with respect to the fixing member while maintaining the inclination angle and the inclination direction of the shaft member once determined.

  In the above inventions (inventions 1 to 3), the receiving seat portion includes a receiving member having the first convex curved surface, and an attaching member for attaching the receiving member and connecting the receiving member to the fixing member, and the receiving member It is preferable that adjustment of the relative position of the first convex curved surface with respect to the fixing member is possible by changing the position of attachment to the mounting member (Invention 4).

  According to the above invention (Invention 4), in addition to the adjustment of the inclination angle and inclination direction of the fixed member with respect to the fixed member, the fixed member with respect to the fixed member only by a simple operation of changing the position of attaching the receiving member to the mounting member The adjustment of the plane position of can also be easily performed.

  According to the joint structure of the present invention, the inclination angle and the inclination direction of the fixing member can be adjusted with respect to the fixing member, and the fixing member can be stably held regardless of the inclination angle and the inclination direction And, it is easy to re-adjust the tilt angle and tilt direction of the fixed member.

  A method for fixing the vertical rail 91 to the support pile 8 using the connector 1 by combining the members constituting the connector 1 described above will be described. First, the support member mounting holes 122a and 122b of the mounting members 12a and 12b and the mounting member connection of the support rod 8 are connected such that the receiving member mounting portions 123a and 123b of the mounting members 12a and 12b are located outside from the upper end of the support pile 8. The mounting members 12 a and 12 b are attached to the support pile 8 by tightening the holes 82 with the bolts and nuts 60. Since the support pile mounting holes 122a and 122b have a square hole shape, the use of the square root round head bolt 60 corresponding to the square hole shape facilitates the bolt / nut fastening operation. Although three attachment member connection holes 82 of the support pile 8 are drilled on each side surface, they can be arbitrarily selected from three in accordance with the required installation height of the vertical rail 91.

  Subsequently, the receiving member 11 is placed on the receiving member mounting portions 123a and 123b of the mounting members 12a and 12b so that the mounting member fastening holes 113a and 113b are on the receiving member mounting holes 124a and 124b, and the receiving member mounting The receiving members 11 are attached to the mounting members 12 a and 12 b by tightening the holes 124 a and 124 b and the mounting member fastening holes 113 a and 113 b with bolts and nuts 61.

Further, since the receiving member mounting holes 124a and 124b are also formed in a rectangular shape, the mounting position of the receiving member 11 in the north-south direction with respect to the support pile 8 is also within the range of the north-south length of the receiving member mounting holes 124a and 124b. It is possible to adjust within. The adjustment width of the attachment position of the receiving member 11 to the support pile 8 in the north-south direction is smaller than the adjustment width in the east-west direction, but the position adjustment in the north-south direction It can be adjusted more broadly.

  Thus, in the present embodiment, by changing the position at which the receiving member 11 is attached to the mounting members 12a and 12b, the relative positions of the receiving member 11 to the support pile 8 and the hook-like member contact surface 111 provided on the receiving member 11 Position adjustment is possible. Therefore, it is possible to easily adjust the planar position of the upper structure 9 of the mount frame for PV panel installation relative to the support pile 8 only by a simple operation of changing the mounting position of the receiving member 11 to the mounting members 12a and 12b.
