Description

TECHNICAL FIELD The present invention relates to a duct support arranged in a ceiling of a building and a pipe support for supporting an air conditioning pipe whose peripheral surface is covered with a heat insulating material on the ceiling, and can cope with various duct shapes and pipe outer diameters in particular. The present invention relates to a pipe support.
The present invention also relates to a pipe support member suitable for use in the pipe support.

  Conventionally, a pipe support has been used as a member for suspending and supporting an air conditioning pipe whose peripheral surface is covered with a duct or a heat insulating material disposed in a ceiling of a building. In such a pipe support, a metal member as in Patent Document 1 is used. However, in the case of a structure in which air conditioning pipes are suspended and supported using such metal bands, a plurality of air conditioning pipes cannot be suspended and supported using a single metal band. Accordingly, it was necessary to use a metal band. In addition, there are many cases where sufficient illumination cannot be obtained at the construction site, and if the state can be clearly seen, a simple band expansion / contraction work is a heavy burden for an actual worker.

  Furthermore, in the metal pipe support that is widely used, as pointed out in Patent Document 2, the pipe supported in the substantially horizontal direction by the hanging fitting (horizontal pulling pipe) Due to its own weight, there are cases where problems such as collapse of the pipe covering part and tearing of the pipe covering part occur. Such crushing and tearing of the pipe covering portion causes a decrease in the heat insulation and heat insulation functions of the pipe, and there is a problem that it may cause a problem on the air conditioner such as the occurrence of condensation and heat loss. In particular, the condensation resulting from the air conditioning piping oozes out as condensed water on the ceiling because the air conditioning piping is installed behind the ceiling. When this leachate dries, it becomes a stain on the ceiling board, and there is a problem of harming the aesthetics of the room.

  In addition, it is customary that construction conditions such as factory production do not ensure uniformity at construction sites, and there is a need for flexible work operations that meet the actual conditions of construction sites. However, due to the flexible construction work, there is a high probability that the construction work will be time-consuming and the installation state of the air-conditioning pipe and the pipe support to the building after the construction work will not be as designed. Therefore, it has been proposed to support the suspension using magnetism as in Patent Document 3. However, it is necessary to use dedicated equipment using magnetism for the hanging metal fittings, which makes it impossible to use general-purpose hanging metal fittings, resulting in a problem that the equipment cost remains high.

  In Patent Document 4, pipe fasteners for commercial refrigerators and showcases are proposed. However, such a pipe fastening fitting is attached to piping on the cooling device side such as a commercial refrigerator or a showcase, and cannot be used as a member that supports the air conditioning piping suspended from the ceiling. was there.

FIG. 3 is a detailed configuration diagram of a pipe support member showing an embodiment of the present invention. FIG. 4 is a plan view of a flexible band showing an embodiment of the present invention. In addition, about the same member in each figure, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

The pipe support of the present invention is used, for example, to suspend and support the air conditioning pipe 40 on the ceiling, and is mainly composed of two parts of the pipe support member 10 and the flexible band 30. Ceiling suspension bolts 50 are previously provided on the ceiling at regular intervals for suspension support.
The pipe support member 10 includes a mounting main body portion 12, a head portion 14, a bolt mounting opening 16, a band guide portion 18, and a protruding member 22 as a band fixing portion 20.

  The attachment main body 12 has substantially the same width as that of the flexible band 30. For example, a metal material having high rigidity and easy plastic processing such as steel, aluminum alloy, brass, and copper alloy may be used. The mass productivity may be improved as a resin. The resin may be any general-purpose plastic material, such as vinyl chloride resin, polyether resin, polystyrene resin, polypropylene resin, and the like, and these plastic materials and fiber reinforced plastic materials such as glass fibers and metal fibers.

  The head portion 14 has a shape bent to the side opposite to the mounting side of the flexible band 30 of the mounting main body portion 12, and is suspended from the ceiling in order to increase the rigidity when fixed to the ceiling suspension bolt 50. The reinforcing portion 142 is bent on the side opposite to the mounting side of the bolt 50. The bolt attachment opening 16 is provided in the head portion 14 and the ceiling suspension bolt 50 is inserted therethrough. The shape of the bolt mounting opening 16 is preferably, for example, a round hole or a square hole, and is large enough to allow the ceiling suspension bolt 50 to be inserted, so that the ceiling suspension bolt 50 can be easily inserted. For example, the inner diameter may be φ. After engaging the bolt mounting opening 16 with the ceiling suspension bolt 50, as shown in FIG. 2, the operator attaches the screw 52 to the ceiling suspension bolt 50 so that the bolt mounting opening 16 is on the ceiling. This prevents the suspension bolt 50 from being detached.

The band guide portion 18 is located on the insertion side of the flexible band 30 of the attachment main body portion 12, is located at a distance d ₁ that is larger than twice the thickness t of the flexible band 30, and is flexible. It has a structure that can be accommodated even when two bands 30 overlap each other. The band guide portion 18 includes bent portions 182 and 184 located at both ends of the flexible band 30 on the insertion side, and a gap portion 186 larger than the width w ₁ of the protruding member 22 is provided between the bent portions.

The protruding member 22 is inclined toward the insertion side of the flexible band 30, and the tip 222 of the protruding member 22 is in a position where it can penetrate into the insertion opening 32 of the flexible band 30. The band fixing portion 20 is made possible by engaging the protruding member 22 with the insertion opening 32 of the flexible band 30 and bending the protruding member 22 in the direction in which the gap portion 186 of the band guide portion 18 is positioned. The flexible band 30 can be fixed to the attachment main body 12.

The protruding member 22 has a narrowed tip 222, and a base 224 of the tip 222 is formed wider than the shaft 226 of the protruding member 22. For example, the opening angle θ of the tip 222 may be 45 to 120 degrees, and preferably 90 degrees. The width w _{2 of the} base 224 is wider than the width w ₁ of the shaft portion 226. The width w _{2 of the} base 224 is slightly larger than the insertion opening 32 of the flexible band 30, and the protruding member 22 is inserted into the insertion opening 32 and is generated in the flexible band 30. It is preferable to prevent the protruding member 22 from coming out of the insertion opening 32 by elastic deformation.
The window portion 24 is provided for punching the projecting member 22 from a rectangular sheet metal material, and is obtained by removing the attachment main body portion 12 into a window shape. By providing the window portion 24, the plastic deformation of the rectangular sheet metal material that occurs when the protruding member 22 is punched into the mounting body portion 12 does not affect the processing shape of the mounting body portion 12 or the protruding member 22. . For example, when the thickness of the sheet metal is about 1 mm, the clearance between the window portion 24 and the base portion 224 is set to a shape that ensures a gap of about 2 to 5 times the thickness of the sheet metal.

  The flexible band 30 suspends and supports the air conditioning pipe 40, and the width of the flexible band 30 is such that the heat insulating material is compressed and deformed to improve the heat insulating performance even when the air conditioning pipe 40 is covered with the heat insulating material. In order to avoid the influence, it is preferable to have a sufficient width, for example, a width of about 50 mm to 100 mm. The thickness of the flexible band 30 may be determined so as to have a strength necessary for hanging and supporting the air conditioning pipe 40, for example, a thickness of about 0.5 mm to 5 mm. Since the flexible band 30 is inserted into the band guide portion 18 and is fixed to the mounting body portion 12 by the band fixing portion 20, the air conditioning pipe 40 can be held in a predetermined posture, for example, horizontally with respect to the ceiling. .

  The flexible band 30 may be made of a material that does not easily condense. Materials that are difficult to condense include plastic materials such as vinyl chloride resin, polyether resin, polystyrene resin, and polypropylene resin, and these plastic materials and fiber reinforced plastic materials such as glass fiber and metal fiber.

For example, a polygon such as a pentagon or a heptagon, a round hole, a flat hole, or an oval hole can be used so as to match the tip shape of the protruding member 22. Etc. can be used. The round hole is suitable when the protruding member 22 is a round bar-shaped bar. Polygons such as pentagons and heptagons are suitable when the protruding member 22 is a flat protruding plate material and the tip has a protruding end shape. The shape of the insertion opening 32 may have a polygonal shape such as a triangle or a quadrangle, or a concave portion such as a star shape. When the flexible band 30 suspends and supports the air conditioning pipe 40, the insertion openings 32 are provided at appropriate intervals so that the openings do not expand to the adjacent insertion openings 32 due to insufficient strength. And good. In the embodiment shown in FIG. 4, a pentagonal opening 322, a round hole opening 324, a small pentagonal opening 326, and a round hole opening 328 are repeatedly provided in this order as the insertion openings 32.

  A procedure for attaching the air conditioning pipe 40 to the ceiling using the pipe support of the present invention having the above configuration will be described. Ceiling suspension bolts 50 are previously provided on the ceiling at regular intervals for suspension support.
