Description

[Detailed description of the invention] The present invention relates to a method for connecting pipe pillows for piping.

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

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 portion or intermediate portion of the piping, and to connect the tube columns at each pitch portion.

The present invention has been made in view of such circumstances, and embodiments thereof will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a rectangular tube column when viewed from the front, and the tube column 1 is made of non-magnetic material such as plastic, FRP, resin concrete, concrete, etc. A through hole is formed.

That is, the tube column 1 is composed of an upper split member 2 and a lower split member 3 which are divided into two at the center in the height direction, and these have semicircular recesses 6 and 7 on opposing surfaces 4 and 5, These semicircular recesses 6 and 7 constitute the through hole.

Both sides of the semicircular recess 6 of the upper split member 2 and the lower split member 3
Each of the facing surfaces 4 and 5 located on both sides of the semicircular recess 7 has a connecting surface distributed left and right with respect to the semicircular recess 6 and 7 and at a central position in the thickness direction (front and back direction). pin(
An example of a convex part) 8A, 8B and a pin insertion hole (an example of a concave part) 9
A and 9B are provided facing each other.

In the figure, a coupling pin 8A is provided on the left side of the upper split member 2, and a pin fitting hole 9B is provided on the right side, and a pin fitting hole 9A is provided on the left side of the lower split member 3, and a coupling pin 8B is provided on the right side. However, this may be configured such that, for example, feeding pins are provided on both sides of the upper split member 2.

On the other hand, one or more coupling pins 11 and pin fitting holes 12 are provided on the upper surface 10 side of the upper split member 2, and similarly coupling pins 14 and pins are provided on the bottom surface 13 side of the lower split member 3. A fitting hole 15 is provided.

These coupling pins 11 and 14 and pin insertion holes 12 and 15 constitute a bonding agent when stacking the tube columns 1.

A vertical binder flow path 16 is formed from each of the pin fitting holes 9A, 9B, and 12.15, and these binder flow paths 16 are connected to the binding pins 8A facing each other in the vertical direction.

Open through 8B, 11.14.

Furthermore, a communication passage 17 in the left-right direction is formed in the upper part of the upper parting member 2 and in the lower part of the lower parting member 3.

Therefore, as shown in FIG.
A, 8B are fitted into the pin fitting holes 9A, 9B, and a binder 19 such as concrete IJ or resin is injected from the pin fitting hole 12.

Then, the binder 19 passes through the binder flow path 16 to the fitting portion between the binding pin 8A and the pin fitting hole 9A, and also to the communication path 17.
The binding agent flows through the binding agent channel 16 to the fitting portion between the binding pin 8B and the pin insertion hole 9B, fills these fitting portions, and is then solidified, so that the split members 2 and 3 are Strongly integrated.

The bottom surface 13 side of the lower split member 3 is to be fitted with another pipe post or mount base, and the above-mentioned bonding agent 19 can be injected at the same time as the pipe posts 1 are assembled one by one, or when all the pipes are assembled. This is done all at once after installing the pillars.

When the right coupling pin 11 is the pin insertion hole 12,
Alternatively, when the binder 19 can be injected from the upper end opening of the binder channel 16 in the coupling pin 11, the communication channel 1
7 can be omitted.

Figures 4 and 5 show three different sizes of tube IA.

1B shows a case where a tube-column assembly 20 is constructed by combining ICs vertically and horizontally.

That is, first, the mount base 21 is installed horizontally, and the three largest tube columns 1C are assembled on the left and right on top of the mount base 21, and the endmost tube column 1
Stack and combine one tube column 1C of the same size on C, combine three intermediate dog-sized tube columns 1B on one side of this tube column 1C, and then combine the smallest tube column (the one shown in Figure 1). corresponds to

) IA is combined on the largest tube IC.

As described above, the mutually overlapping tube columns are integrated by fitting the coupling pins 11. There is.

In addition, P in FIG. 4 indicates the joint between the bisecting members 2 and 3, and H
indicates a joint between the tube columns or between the tube column and the mount base 21.

Here, the latter joint pitch is taken into consideration so that tube columns of the same size or different sizes can be combined with each other without any problem.

The assembly order of the tube-column assembly 20 is as follows: mount base 21
The lower pipe column group is installed on top, and the upper pipe column group is stacked one after another on the lower pipe column group, and in the case of pipe column groups on the same level,
It is desirable to support the tube on the lower split member and then cover it with the upper split member to integrate it.

As described above, according to the present invention, the upper splitting member and the lower splitting member work together to hold the pipe and at the same time fit together, the fitting portion between the concave portion and the convex portion, and the pipe pillars are stacked and simultaneously fit together. By injecting a binder into the fitting part of the concave part and the convex part and solidifying it, this clamping and stacking posture can be firmly joined with quick work.
It can be done easily and accurately.
