DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
The fixture of the heat insulation cladding tube which concerns on this invention fixes the heat insulation cladding tube whose cross section cut | disconnected at right angles with respect to the length direction is elliptical shape. In the present invention, a heat-insulated coated tube means that two synthetic resin tubes coated with a coated thin film are arranged at the center, and the outer peripheral surface of the coated thin film is coated with a heat insulating material layer. Is a structure coated with a skin film (for example, see JP-A-11-82875). A signal line may be arranged inside or outside the coating thin film. The size of the heat insulation cladding tube can be selected in the range of 3 to 7 cm in the major axis and 2 cm to 5 cm in the minor axis depending on the building to be constructed and the location in the building.
[0007]
The fixing device for a heat insulating cladding tube according to the present invention has a flat plate-shaped wall surface fixing portion at the bottom, and a fixing arm for fixing the heat insulating cladding tube at a central portion in the length direction of the flat wall surface fixing portion. The cross section cut at right angles to the length direction has a structure similar to the outer shape of the vertical cross section at the maximum diameter of the overhanging ridge (kagane ridge) and is integrally attached, and surrounded by this fixed arm The space portion is a portion in which the heat insulating coated tube can be fixed vertically or horizontally. The flat plate-shaped wall fixing part below is for attaching and fixing the insulation cladding tube to the floor surface, wall surface, ceiling, etc. by contacting the floor surface, wall surface, ceiling, etc. along the installation route. is there. The flat wall surface fixing portion is provided with screw fixing holes at the center and / or both ends in the length direction. The size of the plate-like wall surface fixing part can be selected in the range of 5 cm to 10 cm in length and 1.5 cm to 5 cm in width.
[0008]
In the flat plate-like wall fixing part, the cross-section obtained by cutting the fixing arm for fixing the heat insulation cladding tube at a right angle with respect to the length direction at the center part in the length direction is the vertical cross section of the overlapping wall. It has a structure similar to the outer shape and is integrally attached. At both ends in the length direction of the flat wall surface fixing part, it is convenient when a plurality of fixing tools are connected to each other by providing convex protrusions on one side and concave grooves on the other side.
[0009]
The flat wall surface fixing part has such a dimension that the space on the lower side of the fixing arm can fix the long diameter of the elliptical heat insulating cladding tube from both the left and right sides with the heat insulating cladding tube being placed sideways. (See FIG. 2 below). It is preferable that the maximum dimension of the lower left and right inner wall surfaces of the overlapped ridge is about 5 to 20% smaller than the major axis of the elliptical heat insulating cladding. Since the outer periphery of the heat insulation coated tube is covered with a heat insulating material layer, the heat insulating material layer is compressed and securely fixed when held by a fixture having a smaller size. It is preferable that both the left and right inner wall surfaces on the lower side of the pile are arcuate so as to come into surface contact with the arcuate outer circumferential wall surface of the elliptical heat insulating cladding. The flat wall fixing part is also sized so that the space on the lower side of the fixing arm can fix the long diameter of the elliptical heat insulating cladding tube from above and below with the heat insulating cladding tube being vertical. (See Fig. 3 below). It is preferable that the maximum dimension of the lower central portion and the upper inner wall surface of the stacked ridge is about 5 to 20% smaller than the major axis of the elliptical heat insulating cladding.
[0010]
In the fixing tool for a heat insulating coated tube according to the present invention, the fixed arm is discontinuous at the opening, and the tip ends of both the fixing arms are V-shaped and extend toward the opening. The discontinuous portion of the fixed arm functions as an insertion port when the heat insulation coated tube is inserted into the space surrounded by the fixed arm. The part extended in V shape on the upper side functions as a guide part at the time of inserting a heat insulation cladding tube. The interval between the discontinuous portions of the fixing arm is preferably about 10 to 90% smaller than the minor axis size of the elliptical heat insulating cladding tube, depending on the rigidity of the material for preparing the fixture. In addition, although an opening part can be provided in arbitrary positions, such as the upper side, right side, left side, and upper right side of a fixing tool, it is preferable to provide in an upper side. In addition, the opening can be held by a fixed arm by making the heat insulating cladding tube having an elliptical cross section smaller than the short diameter, but the opening can be held by a band, string, clip, etc. It can also be securely held by pressing with a tool.
[0011]
The fixture of the heat insulation coating tube which concerns on this invention can be prepared from the material excellent in rigidity, such as a metal, wood, and a synthetic resin. Synthetic resins are preferred because they can be produced in large quantities by the injection molding method. Examples of the synthetic resin include olefin resins such as polyethylene and polypropylene, styrene resins such as ABS resin and rubber-reinforced polystyrene, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polycarbonate, and polyphenylene oxide. Of these, olefin-based resins are preferred from the balance of cost and physical properties.
[0012]
In order to construct a heat insulation coated tube using the heat insulation coated tube fixture according to the present invention, first, the fixture according to the present invention is installed along a route such as a wall surface, a floor surface, or a ceiling on which the heat insulation coated tube is constructed. stop. The fastening method at this time may be temporary fastening. Next, the heat insulating coated tube is pushed into the space surrounded by the fixed arm from the V-shaped extending portion of the fixing tool. The heat insulation coated tube pushed into the space surrounded by the fixed arm is aligned vertically or horizontally depending on the position.
