Description

  The present invention is a construction for fixing a relatively large attachment such as a photovoltaic power generation panel, an antenna, a solar water heater, etc., or a stand for supporting the equipment to an attachment base such as a structure such as a building or the ground. The present invention relates to an attachment support unit and an attachment support structure that can be suitably used.

  As a method of installing relatively large equipment such as solar power generation panels, antennas, solar water heaters, etc. on the ground, steel pipe piles are driven into multiple places on the ground, and the above equipment is placed on the upper end (pile head) of these steel pipe piles. There is a construction method (hereinafter also referred to as a pile installation method) in which a pedestal for supporting the frame is bolted and a plurality of steel pipe piles are used as a foundation for supporting the gantry and a device attached to the gantry.

By the way, in the operation of driving the steel pipe pile into the ground, the steel pipe pile may be driven with a slight inclination with respect to the vertical due to, for example, variations in the density of the soil layer.
In many cases, the inclination of the steel pipe pile driven into the ground with respect to the vertical is negligible. However, for example, when a relatively large installation such as the above-mentioned mount is supported by a plurality of steel pipe piles, the slope of the steel pipe piles is constructed by ensuring a relatively large span between the steel pipe piles. The effect on is increased.

This will be described with reference to the explanatory model diagrams of FIGS.
FIG. 18A illustrates a case where a long bar B is fixed on a steel pipe pile 120 that is vertically driven into a plurality of locations on the ground 110 and the bar B is supported in the horizontal direction.
The several steel pipe pile 120 is arrange | positioned and installed in the ground 110 at intervals mutually. Bar material B is being fixed on pile head 120H which is the upper end part of the portion projected on ground 110 of each steel pipe pile 120. The upper end of each steel pipe pile 120 has the same projecting dimension from the upper surface 111 of the ground 110.

If the separation distance (span) between the piles 121 and 122 is long, the deviation amount of the bar B with respect to the upper end of the second steel pipe pile 122 becomes large. For this reason, the case where the bar B cannot be fixed to the upper end of the second steel pipe pile 122 occurs.

In the above-mentioned pile installation method, in order to realize horizontal support of the installation even if the steel pipe pile driven into the ground is inclined with respect to the virtual vertical axis, both sides of the pile are installed between the pile head and the installation. In addition, the angle (tilt angle) of the installed object with respect to the pile head is adjusted by inserting one or more shim plates laminated so as to have different thicknesses (hereinafter referred to as the first conventional technique).
A plurality of shim plates with different thicknesses are prepared, and the angle is adjusted by inserting between the pile head and the installation object at the site.

In addition, as a technique for supporting the installation object by adjusting the angle on the foundation, there are disclosed techniques disclosed in Patent Documents 1 and 2 below.
In Patent Document 1, an antenna device having a large radiator has a hemispherical convex portion at the base end of a support column (installed object) formed at the tip of the radiator fixed to a basic support column (base). Pushing / pullable fixing means for fixing the support column in three directions to an enclosure that is slidably abutted on the recess of the support column adjustment unit and is connected to the support column angle adjustment unit and surrounds the base end of the support column And a structure in which the angle of the support column can be adjusted in an arbitrary direction is disclosed (hereinafter referred to as the second prior art).
