Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of installing a signboard support frame which is easy and easy to install and is strong against wind pressure.

[0002]

2. Description of the Related Art When installing a signboard or the like on the ground where it is easy to see along roads, railroad tracks, etc., the support frame of the signboard is made of wood logs, square timbers, etc. 1 or the sign frame 1 of the signboard 1 shown in FIGS. 1 and 2, the bracing frame 3, the beams 4, 5, 6 and the base 7 constitute a signboard support frame unit. The signboard support frame 8 is installed on the ground 11 by a method of connecting a plurality of sets by connecting beams 9 and 10 and fixing it to an anchor bolt 13 of a concrete foundation 12 provided in the ground 11. Was.

However, when the support frame of a signboard or the like is made of timber logs, lumber, etc., not only is it inferior in strength and durability, but there are many problems such as acquisition and transportation of logs. ,
Almost disappearing, the method of concrete foundation construction has a drawback that it requires necessary raw materials, tools, and man-hours for storing and transporting them, and that the construction period is long.

Further, when the support frame of the signboard is fixed on the concrete foundation surface of the ground, it is proportional to the product of the wind pressure received by the signboard surface and the distance from the center point of the signboard surface to the base 7 shown in FIG. Since the bending moment to be applied acts concentratedly on the point where the pillar frame 2 and the bracing frame 3 of the signboard supporting frame are in contact with the base 7, it has a sufficient cross-section coefficient to counter this and is relatively It requires a large square pipe and the like, which is expensive.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an installation method for firmly fixing a support frame such as a signboard to the ground without requiring concrete foundation work.

[0006]

[Means for Solving the Problems] In the leg portion of the signboard support frame,
Providing a plurality of sets of guide frame pieces that regulate the driving angle, and after driving the stake-shaped fixture along the guide frame piece into the ground, a means for fixing the legs of the signboard support frame to the stake-shaped fixture. It was taken.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described in detail below.

The column frame 2, the bracing frame 3, the beams 4 shown in FIG.
5, 6 and the base 7 are integrally formed, bolt through holes 14, 15, 16 shown in FIG. 5 are provided, and guide frame pieces 17, 18 facing each other with a space of 0 around the bolt hole 14 are provided on the ground. Is fixed to the beam 6 in the vertical direction by welding or the like, and the guide frame pieces 19 and 20 which are also opposed to each other around the bolt hole 15 are bent at an angle inclined forward with respect to the wind pressure direction received on the signboard surface. It is fixed to the frame 3, and the guide frame pieces 21 and 22 facing each other around the bolt hole 16 are inclined at an angle inclined backward with respect to the wind pressure direction.
The signboard support frame 23 is fixed to the column frame 2, and a plurality of sets of the signboard support frame 23 are appropriately connected by the beams 9 and 10 shown in FIGS. 3 and 4,
The grounded ground 11 is made to stand upright by the base 7.

Next, because of the positioning of the signboard support frame, the width D shown in FIG.
A peg-shaped fixture 30 having a head 24, a tip 25, and bolt holes 26, 27, ... 29 is provided in the direction of arrow A in FIG.
When the bolt holes 26 shown in FIG. 8 have been driven into the ground along the lines 7 and 18 and have reached a sufficient depth corresponding to the bolt holes 14 shown in FIG. Tighten the hole 14 and the peg-shaped fixture 30 with the bolt 33,
Fix it. When there are relatively large stones in the ground and the plow-shaped fixture cannot be driven to a sufficient depth, the bolt holes 27 ,. 29 is appropriately selected and fixed so as to match the bolt hole 14. The above work is performed at three locations shown in FIG.

Subsequently, along the guide frame pieces 19 and 20 shown in FIG. 5, which are inclined forward with respect to the wind pressure direction, in the direction of arrow B,
Further, the guide frame pieces 21, 22 inclined rearward with respect to the wind pressure direction
4, the plow-shaped fixtures 31 and 32 are driven into the positions shown in FIG. 4, respectively, and the signboard support frame is fastened with the bolts 33 to complete the installation.

[0011]

The method for installing a signboard support frame of the present invention does not require any concrete foundation work, so not only can the construction period be significantly shortened, but also the storage of materials, tools, etc. necessary for foundation work, In addition, there is no need for transportation to the installation site.

Since the leg portion of the signboard support frame of the present invention has a guide frame piece which is inclined in the direction vertical to the ground, and in the wind pressure direction and the anti-wind pressure direction, the peg-shaped fixing tool can be moved in a predetermined direction. It is easy to drive, installation of the signboard support frame is extremely easy, and it is greatly inclined in the wind pressure direction and the counter wind pressure direction,
Since there is a peg-shaped fixture that acts as a brace, it can be installed firmly.

Further, since the guide frame piece is fixed to the leg portion of the signboard support frame by welding or the like, the section modulus of the leg portion against the bending moment is significantly reinforced, and an extremely strong signboard support frame body is provided. There are numerous effects such as being able to
It is a useful invention.
