Such a positioning means can be formed separately from the cover 21 and the substrate 20, and can be attached after the both are locked. Further, such a positioning means can be applied to each of the covering means 4.

In the above configuration, the procedure for installing the piping will be described below. First, the piping route to the surface of the building wall 6 or the like is confirmed and marked. Next, as described with reference to FIGS. 1 to 5, 8, and 14, the substrate 20 of the coating means 4 a to 4 c is inserted into the holes 33, 34, and 24 together with the pipe holding member 22 at a predetermined position on the surface of the wall 6. And fixed in a fixed relationship with the screw 35. Coating means 4
The board 20 in c is further firmly fixed to the wall surface 6 by screws (not shown) using the mounting holes 43. If the length of the heat-insulating coated pipe 1 is long, the substrate 20 of the coating means 5 is attached to a desired position on the wall surface 6 together with the pipe holding member 22 in a fixed relation with the pipe holding member 22 by screws 35 as described above. Next, the heat-insulated coated pipe 1 is cut into a predetermined length, the heat insulating material 12 and the cover 13 at both ends are cut off to expose the pipes 11 at both ends, and the desired heat-insulated coated pipe 1 is cut.

According to the present embodiment, a plurality of heat-insulated coated pipes 1 having a rectangular outer shape in which a heat insulating material 12 and a cover 13 are sequentially coated integrally are used on the outer periphery of the pipe 11, so that assembled parts are used. The number of points can be reduced, and the assembling work at the site can be performed easily and quickly. Therefore, the work efficiency can be improved, and as a result, the construction cost can be reduced. The covering means 4a to 4c of the joint member 2 includes a substrate 20, a cover 21, and a pipe holding member 22, and has a small number of assembly parts. Further, the heat insulating material 3 has a split groove formed at one place along the axial direction. 19, the joint member 2 can be covered, and the position of the cover 21 is restricted when the cover 21 and the substrate 20 are locked so that the mounting position of the cover 21 is not shifted. Further, the assembling work can be performed easily and quickly, which contributes to the improvement of the work efficiency and the cost reduction. Also, the cover 1 of the heat-insulating coated pipe 1
Since the outer surface of the end of the cover 21 in the covering means 4a to 4c, 5 for covering the end in 3 is formed on the inclined surface 31, a natural sense of unity can be given to these joints. Further, as described above, since the square heat-insulated coated pipe 1 in which the heat insulating material 12 and the cover 13 are integrally coated sequentially on the outer periphery of the pipe 11 is used, if the pipe diameter is set to be the same as the conventional example described above, The external dimensions can be reduced, so that the installation area can be reduced as much as possible and can be made as inconspicuous as possible.

If the heat-insulating coating pipe 1 is fixed to the wall 6 by the fixing coating means 5, the coating means 4a to 4c such as the joint member 2 need not be fixed to the wall 6. In addition, the present invention can be variously changed in design without departing from the basic technical idea.

[0030]

As described above, according to the present invention, a plurality of heat-insulated coated pipes having a square outer shape are used by sequentially covering the outer periphery of the pipe with a heat-insulating material and a cover. The number of parts to be assembled can be reduced, and the on-site assembling work can be performed easily and quickly. Therefore, the efficiency of construction work can be improved, and as a result, the construction cost can be reduced. In addition, since the above-described heat-insulating coated pipe is used, if the pipe diameter is set to be the same as the conventional example, the outer dimensions can be reduced,
Therefore, the installation area can be made as small as possible, and it can be made as inconspicuous as possible.

Since the covering means is composed of the substrate, the cover, and the pipe holding member, the number of assembly parts is reduced, so that the assembling work can be performed more easily and quickly, and the work efficiency can be improved. It can contribute to cost reduction.

Further, the end of the cover of the heat-insulating coated pipe is covered with the end of the cover of the covering means, and an inclined surface which becomes gradually thinner toward the tip end is formed on the outer surface of the end of the cover of the covering means. Thereby, a natural sense of unity can be provided at the joint between the cover of the heat-insulating coated pipe and the cover of the coating means.
