Description

  The present invention relates to a height adjusting member that is installed between a gantry and a supporting member or between supporting members to adjust the height of the supporting member.

2. Description of the Related Art Conventionally, a gantry or a temporary house on which a solar panel or the like is installed generally embeds a plurality of piles in the ground and fixes them to a plurality of buried pile heads. For this reason, height adjustment when the embedding depth of each pile is different and height adjustment when each pile sinks are necessary. In addition, even in a temporary scaffold where many pillars are set up on the ground of a construction site, height adjustment is required if the ground is uneven.
Therefore, in the connection structure in which the upper structure and the steel pipe pile supporting it are connected with hexagon bolts and nuts, a square plate is placed on one side between the L-shaped adjustment bracket and the intermediate bracket that fixes the upper structure. A method for adjusting a height that is good for inserting a predetermined number of shims having U-shaped attachment grooves that open is disclosed (see Patent Document 1). In addition, a cylindrical member with a nut fixed coaxially with the hole provided in the center of the bottom portion is put on the pile head, and the nut is screwed onto a bolt screwed to the cap member of the pile head, while protruding from the cylindrical member. A method is disclosed in which a pedestal is fixed to a bolt via a horizontal adjustment member, and a tubular member is rotated to adjust the pedestal height (see Patent Document 2).

However, the method of inserting a shim between the L-shaped adjustment fitting and the intermediate fitting requires fine adjustment with a plurality of types of shims having different thicknesses. Has a lot of time and effort. In addition, the method of screwing the nut fixed inside the cylindrical member to the bolt attached to the pile head requires a member that fixes the bolt on the pile side in addition to the cylindrical member, so there are many parts and each part Is costly because it requires molding, and when the gantry on which the superstructure is placed is exposed to strong winds, there is a concern that it can withstand one bolt screwed into the cap member of the pile head. .
In view of the above circumstances, the present invention has an object of providing a height adjusting member that has a simple structure and has a small number of parts, has a low cost burden, is easy to adjust the height of the gantry, and can sufficiently withstand strong winds. To do.

The height adjusting member of the present invention is coaxial with a first member in which a rod-like body having an external thread is erected at the central portion of the disk, and a hole in which an engaging portion having an internal thread is formed in the central portion of the disk. A plurality of tubular support members that support a gantry installed in a horizontal direction, and a second member that is rotatable by screwing the joined engagement portion into the rod-shaped body. It is characterized in that the height of the rack can be freely adjusted by interposing it.
And the said height can be adjusted by fixing the said mount on the said disc of the said 1st member which inserted the said rod-shaped body in the said tubular support member, and rotating the said engaging part.
As described above, the height adjustment member is rotatable by the second member screwed to the first member, and the rod-shaped body (for example, a long screw bolt) of the first member is used as a tubular support portion (for example, a steel pipe pile). On the other hand, since the disc of the first member is fixed to the pedestal, the first member does not rotate, but the engaging member (for example, a nut) is screwed into a rod-shaped body (for example, a long screw bolt). Since it is not fixed to a tubular support part (for example, steel pipe pile), it rotates freely. Therefore, the rod-shaped body (for example, a long screw bolt) moves up and down, and the height of the gantry fixed to the disk of the first member can be adjusted.
In that case, the tubular support member into which the rod-like body is inserted is a member in which a disc having a hole in the center is joined to an edge, and the circle of each of the first member and the second member. The plate has a plurality of holes, and the pedestal is fixed with bolts and nuts to adjust the pedestal height, and then the disc of the second member and the disc of the tubular support member are connected to the bolts and nuts. It is preferable to fix with.
Thus, after fixing a mount to a disk of the 1st member with a bolt and a nut and adjusting height, a disk of a 2nd member and a disk of a tubular support member (for example, steel pipe pile) are bolt and nut. Since the gantry is firmly fixed to the tubular support member (for example, steel pipe pile), there is no possibility that the structure on the gantry is detached from the tubular support member (for example, steel pipe pile) even if the structure on the gantry is covered with strong wind. Further, if a plurality of holes are provided in the disk, it is easy to fix with bolts and nuts.
Further, the second member is formed by screwing the engaging portion with the rod-shaped body with the engaging portion facing toward the first member, and rotates the engaging portion clockwise when viewed from the gantry side. Thus, the height can be adjusted to be increased, and the height can be adjusted to be lowered by rotating counterclockwise.
Thus, if the engaging portion (for example, a nut) is screwed into a rod-shaped body (for example, a long screw bolt) with the first member facing toward the first member, the disk of the second member and the disk of the first member are separated. Therefore, it is easy to turn the engaging portion (for example, a nut) with a spanner or turn the disk of the second member with bare hands. Further, the engaging portion (for example, a nut) screwed into a rod-shaped body (for example, a long screw bolt) moves to the disk side when rotated clockwise, and moves to the tip side when rotated counterclockwise. When the two-member disk or engaging portion (for example, a nut) is rotated clockwise as viewed from the gantry side, the pedestal height can be increased, and by rotating counterclockwise, the pedestal height can be decreased.
Here, it is preferable that the rod-shaped body has a length of 10 cm or more, and has a member that stops the engagement portion from rotating clockwise near the tip.
Thus, if a member such as a pin that stops rotation is provided on a rod-like body (for example, a long screw bolt), the engaging portion (for example, a nut) of the second member is a rod-like body (for example, a long screw bolt) of the first member. If the length is 10 cm or more, not only fine adjustment of the rack height but also height adjustment in the case of unevenness of the ground or ground subsidence can be performed.

Since the height adjusting member of the present invention is composed of a disc, a long screw bolt, and a nut, the structure is simple, the construction is easy, the number of parts is small, and the cost is low. Moreover, since a small diameter nut is rotated by rotating a comparatively large diameter disk and a nut is rotated using a spanner, height adjustment is easy. Furthermore, since the height can be adjusted by inserting a long screw bolt into a tubular support member such as a steel pipe pile, it can be easily applied to temporary scaffolds and existing facilities. In addition, if a disc with a hole in the center is joined to the open end of the tubular support member, it can be fixed with the disc of the height adjustment member and bolts and nuts, so that the structure on the pedestal becomes strong in wind. There is no risk of detachment from the tubular support member or the like even if it is heated.

Below, embodiment of the height adjustment member of this invention is described.
FIG. 1 is a view showing a first member of the height adjusting member of the present embodiment, FIG. 1 (a) is a front view, and FIG. 1 (b) is a bottom view.
A first member 10 shown in FIGS. 1 (a) and 1 (b) has a round iron plate (corresponding to the “disk” of the present invention, the same applies hereinafter) 11 provided with a hole 13 on the periphery, and a male screw. And a metal long screw bolt (corresponding to the “rod-like body having an external thread” of the present invention; The round iron plate 11 has six holes 13, and long screw bolts 12 are vertically welded to the center thereof.
Here, the round iron plate 11 of this embodiment has a thickness of 6 mm and an outer diameter of 150 mm, and the long screw bolt 12 has a nominal diameter of 24 mm, a nominal length of 130 mm, and a pitch of 3 mm. However, these dimensions are merely examples, and are not necessarily limited to these dimensions.

2A and 2B are diagrams showing a second member of the height adjusting member of the present embodiment, in which FIG. 2A is a front view and FIG. 2B is a bottom view.
A second member 20 shown in FIGS. 2A and 2B corresponds to a round iron plate 21 having a hole in the periphery and a nut (an “engagement portion having an internal thread” of the present invention). The same).
The round iron plate 21 is the same size as the round iron plate 11 of the first member, and a long screw bolt 12 is allowed to pass through in the center, but the nut 22 has a hole 23 for blocking, and the first member 10 is formed at the periphery. There are six common holes 24. The six holes 24 on the peripheral edge fix the round steel plate 21 of the second member to the steel pipe pile (corresponding to the “tubular support member” of the present invention; the same applies hereinafter) 30 that supports the pedestal with bolts and nuts. It is a hole for.
The nut 22 is welded to the round iron plate 21 coaxially with the hole 23 formed in the center of the round iron plate 21.
Here, the first member 10 and the second member 20 of the present embodiment are formed of a metal member, and the long screw bolt 12 or the nut 22 is welded to each of the round iron plates 11 and 21, but they are bonded with an adhesive. Alternatively, each of the first member 10 and the second member 20 may be integrally formed of plastic.

Drawing 3 is a front view showing the state where the height adjustment member of this embodiment was fixed to the steel pipe pile.
A round iron plate 31 having a hole 32 into which the long screw bolt 12 is inserted is welded to the end of the steel pipe pile 30 shown in FIG.
The height adjusting member 1 includes a first member 10 in which a long screw bolt 12 is vertically joined to a round iron plate 11 having six holes on the periphery, and a round iron plate 21 having a hole 23 in the center. A second member 20 having a nut 22 coaxially joined to the hole 23, and inserted into the steel pipe pile 30 with the long screw bolt 12 screwed into the nut 22 facing the first member 10 side downward, The round iron plate 21 of the second member is brought into contact with the round iron plate 31 welded to the end of the steel pipe pile 30.
Further, a base (not shown) is fixed in the horizontal direction with bolts and nuts by utilizing the six holes 13 provided in the round iron plate 11 of the first member facing upward.
Here, when the structure to be placed on the gantry is heavy enough not to be blown away even if it is blown by a strong wind, it is not necessary to provide the round iron plate 31 at the end of the steel pipe pile 30. In that case, since the contact area between the round iron plate 31 and the end of the steel pipe pile 30 is small, even if gravity is applied to the contact surface, the frictional resistance is relatively small. On the other hand, the magnitude of the rotational torque of the nut 22 is proportional to the distance from the shaft. Therefore, by applying a rotational force to the outer periphery of the round iron plate 21, or by directly rotating the nut 22 with a spanner or the like, A large torque can be obtained with a small force. Since the round iron plate 21 of the second member is always pressed against the end of the steel pipe pile 30, even if the nut 22 is turned, the long screw bolt 12 and the round iron plate of the first member are used instead of the nut 22. 11 moves up and down. In that case, when the nut 22 rotates clockwise as viewed from the gantry side, the gantry height increases, and when the nut 22 rotates counterclockwise, the gantry height decreases.

As shown in FIG. 4 (b), a round iron plate 31 having an outer diameter of 150 mm joined to one end of a hollow steel pipe has a 28 mm hole 34 into which a long screw bolt 12 can be inserted. There are six holes 35 at the periphery for fixing the second member with the round iron plate 21 and bolts and nuts. And it welds coaxially to the steel pipe pile 30 which has a hollow part larger diameter than the hole 34 of the center part. Note that the dimensions, angles, and shapes shown here are examples and are not necessarily limited to these dimensions.
As shown in FIG.4 (c), the cutting blade 32 welded to the other edge part of the steel pipe pile 30 provides the notch 36 in the center of an edge part, and the cutting blade 32 of an isosceles triangle is formed in the notch. The bottom is inserted and welded.
As shown in FIG. 4 (d), the outer wall at a position of 100 mm, 200 mm, and 200 mm from the tip of the steel pipe pile 30 on which the cutting blade 32 is installed is spaced apart by 120 degrees in the circumferential direction, and has a rectangular shape with a side of 50 mm. The blades 33 are welded obliquely.
The cutting blade 32 is directed to the ground, the steel pipe pile 30 is rotated and dug, and the piled iron plate 31 is buried until it reaches a predetermined height from the ground. Then, the long screw bolt 12 of the height adjusting member 1 is inserted into the hole 34 in the center of the round iron plate 31 of the steel pipe pile 30, and the round iron plate 11 of the first member and a gantry (not shown) are fixed with bolts and nuts. After repeating the same operation for all the steel pipe piles 30, the height of the gantry (not shown) is measured with a level or the like, and the height adjustment member 1 installed on each steel pipe pile 30 is used to adjust the height. The round iron plate 31 of the steel pipe pile 30 and the round iron plate 21 of the second member are fixed with bolts and nuts.
The tubular support member 2 shown here is a steel pipe pile 30 having a cutting blade 32 at the tip and partially embedded in the ground, but the tubular support member 2 necessarily has a cutting blade 32 in the ground. It is not necessary to embed, but it is a short hollow pile with a plate-shaped member joined to the tip, and the plate-shaped member is supported by a bolt on the roof or roof to support the gantry Good.
