JP2015137538A - Spacer accommodating pipes of different diameters - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a spacer that accommodates pipes of different diameters, to be used for holding medium- and small-sized pipes of different diameters, thereby resolving the conventional issues of complexity, lack of structural strength and high prices resulting from when several clamps of different sizes are used for accommodating pipes of different diameters.SOLUTION: A foothold single-pipe clamp 1 directly clamps pipes 6 and 7 of different diameters via a two-piece spacer 5, where the spacer 5 has a circular arch-shaped groove for holding a medium-sized pipe and that for holding a small-sized pipe.

Description

  The present invention relates to a spacer that facilitates clamping of a different diameter pipe.

  Conventionally, single tubes and clamps have been provided to construct construction or architectural scaffolds. In addition to this, four types of ready-made different diameter pipe compatible clamps using a single pipe are provided for practical use.

However, the current situation is that the solid structure and economics of a single scaffold are not so much used in agricultural greenhouses, field enclosures, or other fields that require it.
We will apply the scaffolding single pipe and off-the-shelf clamps for different diameter pipes. There are four types of clamps that are determined according to the size of the pipe material. If the diameter of the pipe material is different, the number of clamp types will increase accordingly. There is no applicability and there is an economic burden and administrative inconvenience.
We try to build a roof part by fixing long pipe materials used in greenhouses using clamps for different diameter pipes, but the fastening bolts are 6mm in diameter, the holding brackets are 2mm thick, and they are light but not strong. Naturally changing wind pressure has not been realized due to resistance concerns. In addition, there were economic disadvantages, such as the market price was twice that of a robust single tube clamp due to the small variety of products.

  A long pipe material of 19 mm or 21 mm is used for a conventional agricultural greenhouse or a rain pipe for tomato cultivation. Since it has a kamaboko-shaped tunnel house structure, there are two entrances at both ends. It feels inconvenient except for those who newly start farming. When organic cultivation is carried out in this, it is necessary to operate the mower and tillage work, the lined pipes interfere with efficiency, and in addition, inconvenience and improvement measures of putting in and out of the tiller are considered and improvement measures are realized Not done.

  I want to make a structure that uses a single scaffolding pipe and a different diameter pipe because of the need for storage shelves to manage equipment and parts in the workplace. Clamps corresponding to this have been put into practical use, but have not been realized due to insufficient strength and high cost. For the same reason, this is not realized even if the necessity of a long and strong erection ladder as needed at the work site is felt.

  The problems to be solved are the lack of strength of clamps for different diameter pipes, the complexity required for the same number of different diameter pipe material types as required, and the efficiency and economic efficiency of high market prices. It is.

  The present invention uses a spacer that is divided into a set of two directly on a single tube clamp, and allows even a plurality of pipe materials having different diameters to be gripped with a strong fastening force of 12 millivolts in diameter. The most important feature is the realization of economic efficiency.

  Although the spacer for different diameter pipes of the present invention is gripped by a strong fastening force of a 10 mm diameter bolt of a single pipe clamp, it is transformed into a spacer and a pipe material from the characteristic shape of the elasticity and two arcs of the material, Rationality that damage does not occur. In addition, the wood was made from thinned wood for economic efficiency. However, there is an advantage that the selectivity according to the purpose of use has been born by making it a convenient shape different from wood because of the ease of forming the waste plastic material.

  It is explanatory drawing which showed the implementation method of a wooden spacer. (Example 1)   Explanatory drawing (Example 2) which showed the implementation method characterized by the both ends of a waste material spacer and the easy fitting

  Even with the strong gripping force of a single pipe clamp, the spacer and pipe material are not deformed or damaged, and the economy of clamping multiple pipes with a set of spacers for different diameter pipes has been realized.

  FIG. 1 is a perspective view of an embodiment in which a 19 mm tube is gripped by a set of wooden spacers of the present invention. FIG. 3 is a perspective view in which the wooden spacer main body has a circular arc shape in which the concave portion can hold a 40 mm tube material, and an arc-shaped shallow groove in which the 19 mm tube material can be held in the central portion. FIG. 5 is a side view showing that the gripping surface is large even if it is strongly gripped only by the central part of the spacer obtained by dividing the 19 mm pipe material into two parts, so that there is no damage and the fastening force has a margin.

FIG. 2 is an example of gripping a medium-diameter 40 mm tube material using only one piece of spacer formed from waste plastic material, and is positioned because both ends of the spacer are fitted in a shape raised from the clamp, Is a perspective view that is easy and has good workability.
FIG. 4 is a perspective view of the shape of the waste plastic material spacer body, which has the same concave shape as that of the wooden part, but is raised at both ends of the portion where the spacer and the clamp are fitted.
FIG. 6 is a side view of an embodiment in which the shape in which both ends of the waste plastic material spacer are raised from the clamp serves as a displacement prevention effect and the workability is good.

A structure constructed of a single scaffold is strong and economical. I would like to use this for the construction of an agricultural greenhouse. If the house pipe material is used only for the roof structure and the side surface is constructed with a single scaffolding, an open and strong plastic house will be realized.
The grip strength of different diameter pipes is increased by the scaffold single pipe clamp and the different diameter pipe compatible spacer. Economic effects can be expected if this is devised and used for building the scaffolding, which is the original purpose.

  It is explanatory drawing which showed the implementation method of a wooden spacer. (Example 1)   It is explanatory drawing which showed the implementation method with which the fitting characterized by the both ends of a waste material spacer was easy. (Example 2)   The wooden spacer main body and the concave portion have two arc shapes for gripping a plurality of pipe materials having different diameters, and the outer shape gripped by the clamp is the same as a single tube.   The waste plastic material spacer main body and the perspective view which made it the same as a wooden spacer except having become the shape where both ends rose.   Implementation drawing of wooden spacers, the size of the space is enough to prevent the gripping force from losing when the two divided spacers come into contact with each other. Side view.   The side view of the implementation figure of a waste plastics material spacer, although it is the same use conditions as a wooden spacer, it can observe the shape where both ends rose.

The present invention uses a spacer that is divided into a set of two parts directly on a single pipe clamp, and can conveniently hold even a plurality of pipe materials having different diameters with a strong fastening force of 10 millivolts. The most important feature is the realization of economic efficiency.

Claims (2)

  A single tube clamp is used to clamp a plurality of pipes with different diameters directly through a two-part spacer. A concave part for gripping the medium-diameter pipe is provided with an arc shape corresponding to the diameter. A spacer for different diameter pipes, characterized by providing an arc-shaped groove and the outer diameter of the spacer being the same size as that of a single pipe, so that pipes having different diameters can be gripped by a set of spacers. The feature is that this special spacer for different diameter pipes is further raised at both ends of the fitting part protruding from the single pipe clamp.
