Description

The present invention relates to an installation method for a gantry having an inclined mounting portion.

Conventionally, steel frames such as C-shaped steel, square steel, and L-shaped steel have been used when constructing the frameworks of various buildings. As a joining method for joining these members, a welding method using a joint or the like or a method of fastening a bolt and a nut is generally used. However, since the members to be joined are not always in the correct positions and orientations as designed, position adjustment (error absorption) means between the members is required. Moreover, when constructing the column base, it is necessary to adjust the position of the pile and the column base, and various construction methods and positioning devices (joints) have been proposed.
For example, (Patent Document 1) is a foundation pile including a base plate that fastens and fixes a building column to a pile head and a spiral rib in a lower body, and the base plate extends radially from the radial center of the foundation pile. A plurality of long holes that are opened at intervals, and a long hole that is opened in a plurality of radial directions by the long holes and a long hole that is opened opposite to the mounting plate attached to the lower part of the pillar of the building. In the overlapping range of the hole and the long hole that opens oppositely, adjust the misalignment between the foundation pile and the column and adjust the mounting angle in the circumferential direction of the column, and fix the board and the mounting plate with the fastening member A joint structure between a foundation pile and a building column is disclosed.

Patent No. 4846378

However, the above conventional technique has the following problems.
(1) In (Patent Document 1), even if the foundation pile is embedded with a misalignment from a predetermined position, the strut of the building can be joined to the foundation pile while adjusting the misalignment. Even in the case of a spiral pile, the purpose is to adjust the angular position in the circumferential direction of the column so that when the prism is used as the column, the predetermined surface of the column can be aligned. The construction and assembly procedures are complicated, the number of parts is large, the construction takes time, and there is a problem that the mass productivity and workability are lacking.
(2) Further, in (Patent Document 1), a plurality of long holes arranged radially at a predetermined angle on a substrate welded and fixed to the head of the pile main body and an attachment plate attached to the lower part of the column are opposed to each other. Since the center gap adjustment and the mounting angle adjustment in the circumferential direction of the support column are performed with the established long hole, the adjustment range is limited, fine adjustment is difficult, and versatility and functionality are lacking.
(3) Furthermore, since (Patent Document 1) does not have a height adjustment mechanism, to adjust the height, the depth of the foundation pile itself must be adjusted, but the depth of the foundation pile is adjusted. If the foundation pile is rotated to do so, the board will also rotate together, and the position (arrangement angle) of the radially arranged long holes will change, which may make it impossible to adjust the mounting angle in the circumferential direction of the column correctly There was a problem of lack of versatility, workability and reliability.

The present invention solves the above-described problems, and does not require connection work and position adjustment between a steel pipe pile and a support leg as in the prior art, can significantly reduce the construction time, and can be mass-produced, workable, and assembled. The purpose is to provide a method for installing a gantry with excellent workability.

It can be fixed, and it is excellent in the attachment workability of the coupler.
(7) Since the female thread for fixing the connector to the steel pipe pile is formed at the center of the top plate, the connector can be adjusted at a predetermined angle even if the steel pipe pile is rotated to adjust the height. The long guide hole of the connector and the long hole position adjustment hole of the girder can always be perpendicular to each other, so the steel pipe pile and girder can be adjusted in the horizontal plane.

The steel pipe pile and the connecting tool can be fixed to each other, and the fixing workability is excellent.
(10) Since the two guide holes of the coupling tool are formed at positions where they do not overlap the bottom plate parts at both ends in the longitudinal direction of the upper plate part, a fixture such as a bolt is inserted into the guide hole from below the upper plate part. Thus, when screwing to the girder, the bottom plate portion does not get in the way and is excellent in workability and fixing workability.

  Here, either the low position side support leg installation step or the high position side support leg installation step may be performed first or in parallel. In the low position side support leg installation step and the high position side support leg installation step, one low position side support leg and one high position side support leg may be installed, or a plurality of them may be installed simultaneously.

The construction time can be greatly reduced, and the mass productivity, workability, and assembly workability are excellent.
(2) Adjacent low position side support legs and high position side support legs are connected by having a large beam provided between adjacent low position side support legs and between adjacent high position side support legs. It can be securely connected to form the foundation of the mounting portion, and is excellent in workability.
(3) By having a plurality of small beams extending between the large beam on the low position side and the large beam on the high position side, it is possible to securely connect the large beams having different heights to form an inclined mounting portion. It can be formed and has excellent workability.

Here, for the large beam and the small beam, a groove steel having a U-shaped cross section, a lip groove steel (C channel) having a C-shaped cross section, or the like is preferably used.
Screw fixing is suitably used for fixing the low position side support leg and the high position side support leg to the large beam and fixing the large beam and the small beam.

In addition, if a fixing hole is previously formed in the beam support part and the side part of the beam, the beam support part and the beam can be easily and reliably fixed by screwing, and the workability is excellent.

Here, when forming the internal thread portion at the center of the top plate that is covered with the steel pipe pile, the internal thread portion may be formed directly on the top plate, or only the through hole is formed on the top plate. A member such as a nut formed and formed with a female screw portion on the back surface of the top plate may be welded.
The connector may have a bottom plate portion, a support portion, and an upper plate portion, but square steel is preferably used. This is because the connecting tool can be easily formed by simply cutting the square steel so that the bottom plate portion is short and the top plate portion is long, and the through hole, the fixture insertion hole and the guide hole are formed.
The fixture insertion hole only needs to be large enough to allow a fixture such as a bolt or a tool to be inserted and rotated, and the shape thereof can be selected as appropriate.

By placing the solar power generation panel on the mounting portion , it is possible to install a large amount of solar power generation panels in a short time and promote solar power generation, which is excellent in workability and environmental protection.
