Description

[Detailed description of the invention] This invention relates to a support generally used in civil engineering, architecture, signage, etc.

Specifically, it is concerned with preventing the support from falling sideways or being pulled out of the ground.

Conventionally, in order to prevent the support from falling sideways or being pulled out, a method has been used in which the lower part of the support is inserted into the base of a hole drilled in the center of the board, and both are buried underground.

However, the attachment between the root plate and the support is weak, and the support is likely to be pulled up or pulled up by the structure attached to the support due to wind pressure.

There are some types that have a steel plate welded to the bottom of the support to prevent them from climbing up, or those that have a solid foundation made of concrete.
It is troublesome to bury it, and once it is buried, it is very difficult to dig up and move it.

The purpose of this invention is to provide a support that is easy to assemble and does not fall sideways, pull out, or climb up.

An embodiment of this invention will be explained based on the drawings.The strut body 1 is a steel pipe coated with hard vinyl chloride resin, etc., and an anchor base support part 2 for holding an anchor base 3, which will be described later, is provided at the end. There is.

The anchor base support part 2 consists of two elliptical bulges of synthetic resin provided at an interval approximately equal to the thickness of the anchor base plate, and is integrally molded at the same time as the steel pipe is extruded and coated with synthetic resin. It is what was done.

In addition, make an ellipsoid with a through hole in the center of the synthetic resin mold,
This may be inserted into a predetermined position at the end of the synthetic resin cladding tube and fixed by welding, gluing, or the like.

The anchor base 3 is a disk made of hard synthetic resin, and its thickness is approximately equal to the interval between the bulges of the anchor base support portion described above.

A tube insertion groove 4 equal to the diameter of the support column body is cut from the periphery of the disk toward the center, terminating at the semicircular end at the center.

The width of the groove is slightly larger than the diameter of the support body at the periphery, and slightly smaller at the central semicircular portion, making it easier to fit the column support into the center.

Since the diameter of the central semicircular hole is slightly smaller than the diameter of the main post body, the post is adhered to the center hole of the anchor base by hammering or other methods.

The synthetic resin-coated metal tube is bonded and fixed to the inner wall surface of the center hole of the anchor base due to the elasticity of the anchor base plate and the elasticity of the synthetic resin layer covering the support column.

Moreover, when removing it, it is sufficient to forcefully hit the support column toward the groove opening.

Note that the anchor base is not circular, but may be square as shown in the opening of Figure 3.

In addition, if the thickness is made thicker in the center and thinner in the periphery, the effect can be maintained and materials can be saved.

In addition to the above-mentioned synthetic resin, wood, metal plates, concrete plates, etc. can be used as constituent materials.

In addition to the ellipsoidal shape of the anchor base support, as shown in the opening in Figure 2, an umbrella-shaped protrusion is provided so that the horizontal planes face each other, and the anchor base is sandwiched between these planes. Also good.

Conveniently used when the anchor base plate is thin.

The anchor base prevents the support from falling sideways, rising up, or sinking by supporting the vertical strut of the soil, and its size is closely related to the length of the support.

The across length of the anchor base is 1/2 of the length of the post
It is preferably in the range of 0 to 1/4; if it is smaller than 1/20, the pressure receiving surface for the tonosho will be small and the above-mentioned effect will be poor, and even if it is larger than 1/4, the labor for digging the pillar burial hole will increase. However, the above-mentioned effects remain almost unchanged.

The main body of the column and the anchor base are sandwiched and fixed at the column support, so the column does not tilt relative to the anchor base, and vertical movement is prevented by the bulge of the support. Therefore, the pillars will not sink or be pulled out.

This invention has the above-mentioned structure, is easy to assemble and bury, is highly durable, and can be easily reused in other locations, making it useful as a prop that can be used in various directions.

Claims (1)

[Scope of utility model registration request] At least one anchor base support 2 formed from a plurality of bulges or protrusions is provided at one end of the synthetic resin-coated metal tube 1, and the length across the length is 1/1 of the length of the synthetic resin-coated metal tube. An anchor base 3, which is a plate of 20 to 1/4 and has a pipe insertion groove 4 whose inner core diameter is slightly smaller than the diameter of the synthetic resin-coated metal pipe, is adhered to the anchor base support part. A pillar.
