BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a mounting base for mounting an apparatus according to the present invention.

FIG. 1 is a perspective view of a basic mounting table according to the present invention. The mounting table 11 for mounting the apparatus is an embodiment of the invention described in the specification attached to the application filed by the present applicant in Japanese Patent Application No. 05-213607 and the accompanying drawings. explain.

The mounting base 11 has a mounting column 14 reinforced with a stay 13 attached to the bottom of a base 12 formed of a rectangular frame disposed at the center by welding. An offset type parabolic antenna device 1 for satellite communication similar to the conventional one is mounted on the upper part thereof.

A vertical surface 16 rising from a bottom surface 15 is formed on all sides of the base 12 to form a tray-like frame. Four sets of weight support frame members 17 and 18 made of angle iron are opposed to the vertical surface 16 so that four sets are detachably attached in four directions and extend in the horizontal direction.

A connecting member 19 for defining the width is similarly attached to the distal ends of the weight supporting frame members 17 and 18. The above members are attached and fixed by bolts and nuts 21, respectively.

Weight support frame member 17, 1 made of angle iron
The opposing bottom surfaces of the members 8 are set to have a width just suitable for arranging and stacking the additional weights 22 made of a known concrete block, so that the weight supporting frame members 17 projecting from the four sides are provided. , 18 each having a large number of additional weights 2
2 (not shown) are stacked in a predetermined number so that the mounting table 11 does not tilt or move.

The base 12, the stay 13, the supporting column 14 for mounting the apparatus, the members 17 and 18 for the weight support frame are all structural steel materials, and are subjected to a surface treatment with a molten zinc bath for rust prevention. Is what it is. However, it is of course possible to apply an aluminum alloy material or the like to reduce the weight as required.

The base 12 and the weight support frame member 17,
1 can be fully understood in FIG. 1, but for easier understanding, description will be made with reference to a plan view in FIG. 2 and a perspective view of a main part in a separated state in FIG. 2 does not show the antenna device 1 and the stay 13, and FIG. 3 shows the weight support frame member 17,
18, only one portion is shown.

There are two types of weight support frame members. A linear weight 17 is a first weight support frame member, and a right angle L-shaped material 18 is a second weight support member. It is a frame member. A part of the vertical surface 25 of the first weight supporting frame member 17 is attached to one side of the vertical surface 16 of the base 12, and a part of the horizontal surface 26 is located below the bottom surface 15 of the base 12. On the side.

The end face of the L-shaped portion 27 of the second weight supporting frame member 18 is perpendicular to the vertical surface 16 of the base 12 on which the first weight supporting frame member 17 extends. Adjacent side 16
The first weight supporting frame member 17 is attached with the vertical surface 25 therebetween, and the opposing portions extending in the horizontal direction are in parallel with each other. The tip portions are joined by a connecting member 19 to define a mutual interval.

In FIG. 2, a center line traversing each portion indicates a portion to which a connecting bolt and nut are attached, and FIG. 3 shows a hole for inserting a bolt. The portable additional weight 22 (FIG. 1) mounted and mounted on the horizontal surface of the weight support frame members 17 and 18 is a known and easily available hollow shape used for a block wall or a partition. It is also used as a semi-buried state for concrete blocks and land boundaries, etc.
Solid concrete blocks that are readily available are applied.

As described above, according to the present invention, since the first weight supporting frame member 17 is attached along one side of the base 12, the same as when one side of the base 12 is extended. In addition, since each is configured in four directions, it can sufficiently withstand a deformation force such as bending in any direction.

A rubber sheet disposed between the mounting table 11 and the installation surface when the installation table 11 is installed will be described with reference to FIG. The stay 13 of the support 14 is not shown. According to the perspective view of FIG. 4A, a square rubber sheet 31 having a size similar to the size of the base 12 is provided at the center.
And four rectangular rubber sheets 32 arranged radially around each side of the rubber sheet.

The base rubber sheet 31 is formed by laminating and integrating two rubber sheets so that the center becomes higher. The reason for this configuration is that the lower peripheral portion has the same thickness as the rectangular rubber sheet 32, but here, as shown in the sectional view of FIG. 17 is a portion where the lower surface of the horizontal portion 26 contacts, and the bottom of the central portion of the base 12 lifted by the horizontal portion 26 is set so as to contact the surface of the higher portion 33. .

The first edge of the rectangular rubber sheet 32 is
The lower surface of the horizontal surface 26 of the weight supporting frame member 17 is in contact with the other lower edge of the horizontal surface of the second weight supporting frame member 18. Base rubber sheet 31
Is surrounded by the portion of the first weight supporting frame member 17 because it is restricted by the end face of the horizontal surface 26 and does not slide between each other, so that any horizontal moving load is However, the effect and effect of increasing the resistance can be obtained.

The purpose, action and effect of inserting the rubber sheet as described above will be described. The coefficient of friction between the rubber sheet and the mortar finished surface at the installation location is about 0.9 to 0.6 depending on the situation. , On average about 0.
8 The coefficient of friction between the metal surface constituting the mounting table and the mortar finished surface is about 0.3. The coefficient of friction between the metal surface and the rubber sheet is about 0.4.

As a countermeasure against the fact that the coefficient of friction between the metal surface and the rubber sheet is lower than that between the rubber sheet and the mortar-finished surface, an appropriate adhesive is applied between the metal and the mortar to fix the metal sheet. It is possible to cope with it more fully.

An offset type parabolic antenna having an opening diameter of 1.8 mφ receives a wind pressure of about 900 k at a wind speed of 60 m / s.
g. Therefore, assuming that the friction coefficient between the rubber sheet and the mortar finished surface is 0.8, the total weight is 1,
It needs to be about 200kg.

When the weight is 1,200 kg, it is necessary to correspond to an allowable load per unit area of a roof such as a building. Allowable load per unit area is 1
If it is set to 80 kg / m ² , the installation area, which is the area of the installation table with respect to the floor in contact, needs to be about 7 m ² or more.
