Description

[Detailed explanation of the idea] The present invention relates to a pipe column.

When burying piping underground, make piping work easier,
Moreover, the pipes are supported by pipe pillars in consideration of earthquakes, unreasonable ground subsidence, and various pressure loads that the pipes are subjected to over a long period of several decades.

For example, in the case of underground underground conduits, multiple conduits may be installed in parallel, and in such cases, it is necessary to ensure that the pitch between each conduit is set to the required value.

Therefore, it is necessary to install a large number of tube columns at certain short pitches in the bell section or intermediate section of the piping.

The present invention has been devised in view of the above circumstances, and embodiments thereof will be described below with reference to FIGS. 1 and 2.

Reference numeral 1 denotes a tube column having a rectangular shape when viewed from the front, and the tube column 1 is made of a non-magnetic material such as plastic, FRP, resin concrete, concrete, etc., and a through hole 3 for a pipe 2 is formed in the center thereof. .

The pipe column 1 is divided into two parts at the center in the height direction.
and a lower split member 5, which have a bone frame structure as is clear from the illustration.

Fitting recesses 8 and 9 are formed over the entire thickness of opposing surfaces 6 and 7 located on both sides of the through hole 3 of the upper split member 4 and on both sides of the through hole 3 of the lower split member 5. There is.

The innermost parts of the fitting recesses 8 and 9 are expanded diameter holes 8A and 9A.

FIG. 2 shows a connecting pin 10, which has the same length or approximately the same length as the thickness of the tube column 1, and has a pair of columnar parts 10 at both ends.
A, has 10 A.

Each columnar part 10A of the connecting pin 10 and each fitting recess 8 of the upper split member 4 and lower split member 5 in which IOAs are stacked in two stages.
, 9, aligning its axis with the expanded diameter holes 8A, 9A of the tube column 1.
If inserted in the thickness direction, the upper split member 4 and the lower split member 5
are combined into one.

FIG. 3 shows another connecting pin 11 used in place of the connecting pin 10 of FIG.

This connecting pin 11 has one columnar part 11A and one split part 11B.

According to this connecting pin 11, the columnar part 11A is pushed into the enlarged diameter hole 9A of the fitting recess 9 in the lower split member 5, and the separate part 11B is made to protrude upward.
By knocking in the upper splitting member 4 from the state where the fitting recess 8 of the upper splitting member 4 is in contact with B, it can be integrally combined with the lower splitting member 5.

At this time, the separate portion 11B of the connecting pin 11 is fitted into the enlarged diameter hole 8A of the upper split member 4 due to its elasticity.

On the other hand, a fitting recess 12 is also formed on the side end surface of the upper split member 4.

This fitting recess 12 has an enlarged diameter hole 12A at its innermost portion, and has the same structure as the fitting recesses 8 and 9 described above.

Similarly, the lower split member 5 is also formed with a fitting recess 13 having an enlarged diameter hole 13A.

These fitting recesses 12 and 13 are spaced at equal intervals along their side end surfaces when the upper split member 4 and the lower split member 5 are joined together.

In other words, the distance l from the corner of the tube column 1 to the fitting recesses 12 and 13 closest to it is equal to 100, the distance between the fitting recesses 12 and 13 formed on the side end surface that is flush with each other. There is.

Such a pitch relationship between the fitting recesses 12 and 13 is the same even in tube columns of different sizes.

Therefore, when combining pipe columns of the same size,
Alternatively, when tube columns of different sizes are combined, the fitting recesses of adjacent tube columns always face each other at a plurality of locations.

At each corner in the thickness direction of the upper end surface of the upper split member 4, a key-shaped protrusion 14 and a notch 1 are provided over the entire length in the left and right direction.
5 is formed.

Further, a key-shaped protrusion 16 and a notch 17 are formed at each corner in the thickness direction of the lower end surface of the lower split member 5 in a relationship opposite to that of the key-shaped protrusion 14 and the notch 15, respectively.

In other words, when the two pipe columns 1, 1 are combined in a vertically stacked manner as shown by solid lines and imaginary lines in FIG. 1, the upper split member 4
The key-shaped protrusion 14 is the lower split member 5 of the upper pipe column 1.
The key-shaped protrusion 16 of the lower split member 5 in the upper pipe column 1 engages with the cutout 15 of the upper split member 4 in the lower pipe column 1 from the same direction. There is.

Figure 4 shows tube columns of three sizes, IA, IB, and I.
C are combined vertically and horizontally to form a tube-column assembly 18.
This shows the case where .

That is, first, the mount base 19 is installed horizontally, on which the three largest tube columns 1C are assembled on the left and right, and one tube column 1C of the same size is stacked and assembled on the endmost tube column 1C.
Two intermediate-sized tube columns 1B are combined on one side of this tube column 1C, and the smallest tube column (shown in FIG. 1) IA is placed on top of the largest tube column 1C.

The connecting pins 10 and 11 explained in FIG. 2 or 3 are fitted between the tube columns adjacent to each other in the left and right direction to integrate them.

In addition, in FIG. 4, P indicates the connecting pin 10 or 11, and H indicates a fitting recess into which the connecting pin 10 or 11 is not fitted.

The assembly order of the tube-column assembly 18 is as follows: mount base 19
The upper pipe post group is stacked one after another on the lower pipe post group, and for the pipe post groups in the same stage, after supporting the pipe 2 on the lower split member, cover this with the upper split member. It is desirable to do so in a way that they are integrated.

As is clear from the above explanation, according to the present invention, multiple parallel pipes can be reliably set at the required pitch with respect to each other by a combination of a plurality of pipe columns, and also Since the pitch of the fitting recesses is set as described above, when pipe posts of the same size are combined with each other, or when pipe posts of different sizes are combined with each other, they are always adjacent to each other in the left and right direction. The fitting recesses of the tube columns face each other at a plurality of locations, and they can be combined in any form to form a tube column assembly.

Therefore, it can be particularly advantageously applied when pipes having different diameters are arranged in parallel.

Furthermore, the upper split member and the lower split member as well as the pipe columns assembled with each other in the left and right direction are connected to each other by fitting a common connecting pin into the fitting recess formed in the upper split member and the lower split member. Therefore, the connection work can be done easily and in a short time, and compared to, for example, a method in which projections and recesses are provided on the upper and lower surfaces of the pipe columns and the pipe columns are connected by fitting together, the connection work is easier and faster. Since the pin can span the entire length of the tube column in the thickness direction, the strength against external forces in the width direction and the vertical direction applied to the tube column assembly can be improved.
