Description

According to the present invention, a rectangular pipe that can be easily piped on the indoor and outdoor wall surfaces of a building and can be decoratively attached to the wall surface, a substantially rectangular pipe for indoor and outdoor piping having a trapezoidal shape having a substantially thick plate-like appearance, and the same. It relates to parts of joints.

Generally, pipe materials used for various facilities such as water supply and drainage, sewage, rainwater equipment, fire extinguishing equipment, air piping, etc. in stores and factories, and jointing equipment for various pipe materials are circular, steel pipes, resin pipes, and pipes inside and outside the building. When it is used, it does not look good in appearance, and this is also a factor, and it is often buried in walls and soil. Therefore, it is difficult to install.
Furthermore, many circular pipes are laid in parallel in factories, etc., but the rectangular pipe requires a small space, and the packing, transportation, and storage costs are low and the economy is high.

Building pipes are generally circular steel pipes and vinyl pipes, and there are few non-circular shapes, but it is proposed that the cross section is oval in order to prevent the accumulation and accumulation of solids that accumulate inside. ing. It has been proposed that the egg shape is an egg-diameter tube having an egg-shaped cross section in which a large-diameter arc portion and a small-diameter arc portion are connected by a curve (see Patent Document 1).
As a steel pipe as a water pipe such as a water supply / drainage pipe, a steel pipe whose inner surface is coated with resin is used in order to impart corrosion resistance to the inner surface thereof. For example, vinyl chloride resin attached to the inner surface of a steel pipe is generally widely used, but at low temperatures when it is stored outdoors for a long time in the cold at a piping construction site or used in a cold region. Due to its low impact resistance, the vinyl chloride resin may be damaged, making it difficult to maintain corrosion resistance. Further, a method has been proposed in which the steel pipe and the vinyl chloride resin are separated and each is individually disposed of so that harmful substances are not generated from the vinyl chloride resin after using the hard vinyl chloride coated steel pipe on the inner surface.

Therefore, a technique for coating the inner surface of a steel pipe without using a vinyl chloride resin is being studied. There is disclosed a technique of imparting shape restoration to a cross-linked polyethylene pipe and expanding the diameter by heating and restoring in the steel pipe to cover the inner surface of the steel pipe. Further, a technique of imparting shape resilience to a polyethylene pipe to cover the inner surface of a steel pipe is disclosed (see Patent Documents 1 and 2).

In addition, as long as the above problems do not occur, most of the piping technology is for measures against accumulation of solids or corrosion inside the pipe, and it is a proposal for the shape of the pipe with decorativeness or simplification in piping work. Is almost nonexistent.

If the buried pipe under the floor leaks due to aging or an earthquake in a store or factory, it is difficult to determine the location of the leak, and the construction is forced to be a large-scale construction by stripping the concrete on the floor. Furthermore, major damages such as relocation of machinery and suspension of operation at factories and movement of displayed items at stores are unavoidable.
For this reason, the existing buried pipes were abolished, and tap water was branched from near the meter, well water was branched from near the pump, or near a building that did not hinder, and exposed pipes were installed along the outdoor wall. From there, there is no choice but to branch indoors and use it. However, when outdoors, there is a concern that water may leak due to the rupture of the pipe due to freezing in winter, and a heat insulating material is required. In addition, the exposed piping indoors does not look good and causes a sense of discomfort.
Further, when a large number of pipes are required to be piped in parallel in a factory or the like, a wide piping space is required, but a pipe having a shape capable of piping even in a narrow space is required.

Generally, it is intended for pipe materials used for equipment of various facilities such as water supply and drainage of water supply and drainage of well water, sewage, rainwater, fire extinguishing, etc. in houses, stores, offices, factories, warehouses, etc. Shaped pipe materials are expected. In particular, if the pipe material buried in a factory, store, office, or house leaks, the construction can be done easily without the need for large-scale construction by stripping the floor concrete, and it will look like a waterworks trace. Instead, the existing buried pipes are abolished, and for tap water, rectangular pipes are used so that the decoration is not damaged inside and outside the building and that the pipes can be easily installed indoors. Therefore, it is desired that the indoor exposed piping does not look bad and does not feel uncomfortable. The purpose is to solve the problems of conventional water and gas piping, such as simplification and decorativeness.

In addition to water supply pipes, drainage pipes, sewage pipes, and rainwater pipes used inside and outside buildings such as houses, factories, restaurants, offices, and public facilities, large air pipes used to drive firefighting equipment, air conditioning equipment, and machinery.・ We devised a rectangular pipe for circular pipes of various diameters. Steel pipes and resin pipes that can be easily piped on the inner and outer walls of a building and can be decoratively attached to the wall surface, and are representative of large and small circular pipes with a diameter of 25 mm. We proposed a rectangular tube corresponding to the area.
Its shape is a rectangle or trapezoid with approximately square corners rounded to an R curved surface, and has a vertical width of 10 to 20 mm and a vertical width and a horizontal width in order to secure a cross-sectional area equivalent to an existing inner diameter 25 mm circular pipe. The ratio is 2 to 4, the cross-sectional area is 4 to 10 cm ² , the thickness of the pipe is ² to 5 mm, the appearance of the rectangular pipe and trapezoidal pipe is substantially thick plate, and the inner pipe is not divided or divided. It is a component of a rectangular pipe for internal and external piping of a building and its joint, which is divided into two sections and whose outer surface exhibits various decorative patterns.

The rectangular tube and the trapezoidal tube have a width of 2 to 4 mm and a length of 2 to 4 m on the R curved surface of the corner, and the elbow, cheese, and socket of the same tube shape to which the rectangular tube and the trapezoidal tube can be connected. It has a fitting type that can be joined to the incidental parts of.

The outer surface of the rectangular tube and the trapezoidal tube, which have a substantially thick plate shape, is colored according to the surrounding wall surface, and various patterns, paintings, and photographs are directly printed, and paper. Alternatively, a piece printed on resin is attached with an adhesive to give a decorative property that does not give a sense of discomfort to the surroundings of the building wall surface.

The inner diameters of the elbows, cheeses, and socket ancillary parts of the same pipe shape as a jointing tool for adding, bending, and branching a thick plate-shaped rectangular pipe or trapezoidal pipe, and a sealing tool are approximately thick at the inset type joint. It has almost the same dimensions as the outer shape of the rectangular tube and the trapezoidal tube, which are plate-shaped, and exhibits various decorative patterns on the outer surface of the incidental parts. The thick plate-shaped rectangular tube and the trapezoidal tube are used on the wall surface. The metal fittings to be attached and the heat insulating cover also have various decorative patterns on the outer surface so as not to impair the decorativeness.

According to the present invention, the appearance is an important factor in the case of piping in a building, and a design that does not give a sense of discomfort is also required, especially in stores and restaurants visited by customers. Also, in the case of a factory that requires a large number of pipes, in order to enable many pipes even in a narrow space, the problem is solved by making the cross section of the pipe rectangular and rounding the four corners to make the appearance plate-like. By selecting colors and pictograms that match the indoor and outdoor wall colors by coloring in a single color or pictorial pattern, the usage can be expanded, and the joint parts with various shapes reduce discomfort and at the same time new You can create a space.

In addition, it is generally used for pipe materials used for equipment of various facilities such as water supply and drainage of water supply, well water, sewage, rainwater, fire extinguishing, etc. in houses, stores, offices, factories, warehouses, etc. and joining equipment of various pipe materials. It can be done, especially because the pipe can be piped directly to the wall of the building without burying it in the wall or in the ground, so the construction is easy, the construction period is short, and the rectangular plate shape makes it a circular pipe. Costs are reduced for packing, transportation and storage. In addition, the buried pipe in a small site cannot be mechanically excavated and is manually excavated, but the excavation width is narrow and the excavation labor is greatly reduced, which is expected to shorten the time.
