Description

[Detailed description of the invention] The present invention relates to the invention of a column support mechanism, and attempts to obtain a novel column support mechanism that can provide a stable column support function with a relatively small support structure for the foundation. It is something.

Installing guardrails on the sides of roads and separation fences to separate pedestrian and pedestrian paths, or installing fences, and setting up supports at the foundations when setting up various signs, billboards, pagodas, etc. Conventionally, when setting up such a support, the base end of the support was simply buried, or a part of the anchor protruding from the side of the support was provided at the base end of the support, or the support was Anchor bolts are simply protruded from the bottom and buried and fixed, but in any case with these conventional methods, the construction work on the foundation is quite large-scale.

In other words, in the case where the base end of a column is buried and fixed, at least a hole sufficient to fully insert the column and fill with a setting material such as concrete is required, and a part of the anchor protrudes from the bottom of the column. In this case, the perforation becomes even larger.

However, with anchor bolts protruding from the bottom of the column, even if the diameter of the hole at the foundation is small, the supporting force is obtained from the small diameter anchor bolt, so the depth of the hole needs to be made considerably larger. The large-scale construction work is not substantially improved.

The present invention was devised through research to solve the disadvantages of the conventional ones as described above.
The use of a tubular member as the support column 1 to be set as shown in FIG. However, in the present invention, the anchor member 8 is also provided with an interior portion 8a into the support 1, and a collar member 9 is provided at the upper end and middle portion of the anchor member 8, respectively.
. 10 is fitted onto the inner surface of the lower end of the tubular support 1.

It is clear that the tubular support 1 may be either square as shown in FIG. 1 or circular as shown in FIG. In order to obtain a stable assembly relationship between the
．． Folded portions 9a, 10a are formed on at least both sides of the flange members 9, 10 to achieve a substantially tight bonding relationship with the inner surface of the support member, and in the case of a circular member as shown in FIG. By adopting a structure in which folded portions 9a and 10a are provided on the circumferential side of the ring, a substantially tight bonding relationship is obtained in the same manner as described above.

Regarding the anchor member 8 as described above, the anchor plate 4 may be formed with a bent portion 4a or a branched portion 4b as shown in FIG. 3 to increase the anchor supporting force.

An example of a specific setting state of the support mechanism according to the present invention as described above is as shown in FIG.
A lid body 3 with a screw receiving part 13 integrally formed on the upper end is attached, and an anchor part 8 protruding from the lower end of the column 1 is inserted into a hole 7a formed in the base part 7. Its installation is done by filling and setting a setting material 4, such as cement mortar or paste.

The support mechanism according to the present invention is a guardrail as described above,
It is obvious that it can be applied to road separation fences, fences, signage poles, etc., and if it is relatively large, it can also be used freely for street lighting poles, telephone poles, etc., but it is also suitable for mounting billboards. It can also be used advantageously for things like standing a tower in a graveyard.

In other words, one example of a concrete application state of such a billboard or tower stand is as shown in the above-mentioned FIG. Materials 5, 5 are attached above and below, and these horizontal members 5, 5
The upper flange member 10 and the lid member 3 are attached as described above.
Advantageously, this is done together with the installation of the

That is, the fixing means 6 such as screws can be screwed into the above-mentioned folded part 10a or the screw receiving part 13 through the horizontal members 5, 5, so that the attachment relationship can be formed with a small number of fixing means 6. Moreover, in this case, the plate-shaped horizontal beam 5
acts like a washer and can achieve accurate tightening and fixing by the fixing means 6.

In the case where the horizontal beams 5, 5 are attached to the front and rear of the pillars 1, 1 as shown in the figure, it is clear that the space between the horizontal beams 5, 5 is used for inserting and supporting a tower, etc. Also, the pillar 1
．． 1 and the horizontal beam 5 can be used to attach an advertising board or other display board.

It is clear that according to the present invention as described above, the anchor member 8 is connected to the intermediate portion on the foundation of the tubular support 1 via the collar member 10 attached to the upper end thereof and the fixing means 6. An anchor member 8 with a small diameter is firmly and stably connected to the column 1, and the lower end of the column 1 is connected to the base 7 surface as shown in FIG. If a lateral force acts to tilt the support 1 down, a preferable resistance action will be exerted by the interior portion 8a of the anchor member 8 through the collar member 10 and the fixing means 6 even in the middle part of the support 1, and the lower part of the tubular support 1 will be A collar member 9 attached to the end face and a foundation 7 at the lower end of the tubular support 1
Coupled with the joint support effect on the surface, an effective support function can be achieved, and therefore the base portion 7 of the anchor member 8
A preferable collapse prevention performance can be obtained even if the depth of burial is relatively short, and it goes without saying that the anchor member 8 may have a significantly smaller diameter than the support 1 itself.

Therefore, it is possible to reduce both the diameter and the depth of the hole in the base 7 for supporting the column 1, and in any case, it is possible to greatly reduce the amount of holes to be drilled.
In the case where the foundation 7 is made of stone, bedrock, or a concrete layer, the number of man-hours for drilling the holes 7a is significantly reduced, and the amount of coagulant 4 such as mortar or cement paste is reduced. This is very advantageous because it makes it possible to use fixing means 6 such as screws.
As shown in the embodiments described above, the connection and fixing with the anchor member 8 can be used in common with the attachment of a horizontal member such as the horizontal beam member 5, and although it can have the above-mentioned effects. The structure is simple, and as a result, an effective support effect can be obtained through simple and compact construction, so it is a highly effective idea in practical terms.
