Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a pillow for supporting the Huum's canal whose size can be easily adjusted according to the size of the Huum's canal.

[Conventional technology]

In order to support and fix the conventionally laid pipes, pillow bodies made of wood or synthetic resin are press-fitted at appropriate intervals on the underside of the pipes, and the pipes and foundation plates (Yobicon 9 and Stecon 10 in Fig. 3) are pressed into place. (collectively referred to as the foundation board). Fill the space between the foundation board, the pillow body, and the pillow body with fresh concrete to fix the pillow body.
Huyum's canal is fixed.

[The problem that the idea aims to solve]

However, the pillow body made of wood or synthetic resin is
The concrete base plate called 0 is different in material from the ready-mixed concrete packed between the humid pipe and the base plate, so it is difficult to achieve good integration between the pillow body, the base plate, and the ready-mixed concrete. It was hot.

Specifically, in the case of a wooden pillow body, moisture that has passed through the concrete from the outside seeps into the pillow body that is solidified with concrete, causing the wooden pillow body to rot.

In addition, in the case of a synthetic resin pillow body, when the outside temperature is high, the pillow body expands thermally, causing cracks in the concrete covered with it.

The technical object of the present invention is to provide a pillow for supporting the Huum's canal that overcomes these drawbacks.

[Means to solve the problem]

The gist of the present invention will be explained with reference to the accompanying drawings.

It is used by being placed under the hume tube 1 when laying the hume tube 1, and has a horizontal mounting surface 11 on the bottom surface and an inclined surface 12 on which the hume tube 1 is placed on the top surface. , a plurality of cutting grooves 3 at appropriate intervals in a direction substantially perpendicular to the mounting surface 11;
This invention relates to a pillow for supporting a Huyum tube, characterized in that it is constructed of two concrete pillow bodies 2 on the left and right sides with numbers 4 engraved on the front and rear sides.

[Effect]

The left and right pillow bodies 2 are placed in a facing state and brought into contact with the respective mounting surfaces 11 at a desired installation location, and the inclined surfaces 12 of the left and right pillow bodies 2 form a humerous canal support portion having a V-shaped longitudinal section, The hume tube 1, which is placed on this hume tube support portion, is supported and fixed by the left and right pillow bodies 2.

The pillow body 2 is appropriately cut using cutting grooves 3 and 4 depending on the diameter of the hume tube 1 to be placed.

〔Example〕

The pillow body 2 in the drawing shows a case in which two cutting grooves 3 and 4 are carved on both sides of the pillow body 2. When supporting and fixing a large hume canal, the pillow body 2 as it is is used. When supporting and fixing a small hume canal, the base side of the pillow body 2 is cut off from the cutting groove 3 near the base to create a smaller pillow body 2.
use.

The concrete construction method of this product will be explained with reference to FIG. 3. A concrete layer called a steel base 10 is formed on a base 13. Since this steel cone 10 is not struck with an accurate thickness and inclination, a Yobicon 9 with the desired thickness and desired slope is placed on top of the steel cone 10.
A layer of concrete, called a concrete layer, is poured to form the exact foundation slab as desired. The pillow body 2, which is the product of the present invention, is placed on this base plate in a facing state, and the pillow body 2
The humid pipe 1 is placed on top, and finally concrete 8 is poured to complete the construction.

Figure 2 shows the formwork 5 used when forming the pillow body 2. Excess concrete for laying the foundation slab at the site is filled into the formwork 5 to form the pillow body 2 of the same quality as the concrete used on site. If molded, the base plate and the pillow body 2 will be of better quality.

In the figure, reference numeral 7 indicates a vibrator connecting portion to which a vibrator is applied during curing, and reference numeral 6 indicates a molding plate.

[Effect of idea]

Since the present invention is constructed as described above, it exhibits the following effects.

Since the pillow body is made of concrete, it is well integrated with the concrete poured to fix the foundation plate and the pillow body, and the hume pipe can be supported and fixed with such durability.

Since multiple cutting grooves are cut at appropriate intervals on the front and rear sides of the pillow body, it is easy to cut along the cutting grooves without having to individually mold the pillow body to match the diameter of the humid pipe. Through these operations, it becomes possible to adapt the pillow body to the size of the hume pipe diameter.

On the contrary, this means that it is necessary to prepare only one mold for molding the pillow body that matches the diameter of the hume tube, and therefore costs can be reduced accordingly.
