DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 illustrates an embodiment of a heat insulating base material for building exterior according to the present invention.
Is a base material having a heat insulating function used for a roof, an outer wall, and the like. The base material is formed using a synthetic resin foam made of urethane, styrene, isocyanurate, phenol, or the like. It has a thickness of the order of millimeters, and the front and back surfaces are formed flat. On the surface of the heat insulating base material 1, two concave grooves 2 into which a support member to be described later can be fitted are formed in a left-right parallel manner along the longitudinal direction of the base material 1. Is formed in a substantially U-shaped cross-section in which a support member serving as a rafter can be fitted, and a receiving portion 3 having a substantially convex cross-section is provided at the center of the bottom surface thereof in the longitudinal direction. Downflow grooves 4 capable of draining rainwater are formed along the bottom surfaces on both left and right sides of the vehicle. By providing the required number of concave grooves 2 on the surface of the heat insulating base material 1 in this manner, the assignment of the support members is completed at the same time as the laying of the heat insulating base material 1, so that the work for marking the exterior material supporting member can be performed. It is reasonable to simplify the installation work and improve the workability. The groove 2 provided on the surface of the heat insulating base material 1
The number is not limited to two, and one or more may be provided according to the width of the base material or the like.

The mounting portion 5 is provided on the top surface of the receiving portion 3 in the concave groove 2 along the longitudinal direction, at intervals substantially equal to the greatest common divisor of a plurality of typical mounting intervals by fasteners described later. The mounting portion 5 includes a pair of upper and lower concave portions 5a and 5b recessed from both sides of the base material, and a thin portion 5 between the bottom surface portion 5c of the upper and lower concave portions 5a and 5b.
d. The upper and lower concave portions 5a and 5b are formed in a long groove shape along the longitudinal direction, and are formed in an expanded shape from the bottom portion 5c toward the opening side, and are pressed against the fixing tool or pushed into the fixing tool. The thin portion 5c is formed to have a thickness (specifically, about 5 to 10 mm) through which the fastener can be forcibly pressed to penetrate.

[0009] Further, at the periphery of the heat insulating base material 1, polymerization drainage parts 6 and 7 which can be vertically polymerized so that there is no place where the front and back are directly communicated between adjacent heat insulating base materials.
And the overlapped cover parts 10 and 11 are formed. The polymerization drainage portion 7 recessed along the upper edge of the heat insulating base material 1 has a stepped portion 8 cut down along the upper edge of the surface of the base material 1 to a depth of about half the thickness of the base material 1. And a bank-shaped ridge 9 projecting upward along the entire outer edge of the stepped portion 8 to form a groove-shaped gutter having a width required for drainage. On the other hand, the polymerization drainage portion 6 recessed along the right edge of the heat insulating base material 1 is formed in a gutter shape having the same cross-sectional shape as the above-described polymerization drainage portion 7 at the upper edge portion. By changing the height continuously, it is formed in an inclined shape with a return gradient rising from the water upper side to the water lower side. The polymerization drainage section 6
The water-side end is joined to the right end of the polymerization drainage portion 7 at the upper edge, and the water-side end portion is disposed below the right end of the polymerization drainage portion 7. It is configured such that a slight step is generated at the junction between the drainage portions 6 and 7. Further, the polymerization drainage portion 6 is gently inclined so as to rise from the water upper end to the water lower end. The inclination of the polymerization drainage part 6 is sufficiently smaller than the inclination of a normal roof. When the heat insulating base material 1 is laid on the roof ground, the polymerization drainage part 6 is inclined downward toward the eaves. So that the rainwater that has entered the polymerization drainage section 7 flows down from the right end of the polymerization drainage section 7 to the upper end of the polymerization drainage section 6 and further flows down the polymerization drainage section 6 to be drained. It is.

[0010] The left and lower edges of the back surface of the heat insulating base material 1 can be joined to the above-described superposed drainage portion 6 on the right side edge and the superposed drainage portion 7 on the upper edge in a state of being overlapped from above. Polymerized covering parts 10 and 11 are formed. The overlapped covering portion 11 at the lower edge is formed symmetrically with the polymerization drainage portion 7 at the upper edge, and has a step 12 along the lower edge of the back surface of the heat insulating base material 1 and an outer edge of the step 12. And a ridge 13 along the portion. In the laid state, the overlapped cover portion 11 is joined so as to overlap the overlapped drainage portion 7 at the upper edge of the vertically adjacent heat insulating base material 1. In this bonding state, a drainage cavity is formed between the overlapping polymerization drainage part 7 and the polymerization covering part 11, and the surface of the junction between the adjacent heat-insulating base materials 1 is made flush. It is.

The overlapped cover 10 on the left side of the back surface of the heat insulating base material 1 is formed in the same sectional shape as the overlapped cover 11 of the lower edge described above. Since the polymerization drainage portion 6 is formed in an inclined shape, the polymerization covering portion 10 superposed on the polymerization drainage portion 6 is also formed in an inclined shape rising from the water upper end toward the water lower end. Therefore, the overlapped covering portion 10 is joined so as to overlap the overlapped drainage portion 6 on the right side edge of the heat insulating base material 1 adjacent to the left and right in the laid state. In this joining state, a drainage cavity is formed between the overlapping polymerization drainage section 6 and the overlapping polymerization covering section 10, and the surfaces of the junctions between the side edges of the adjacent heat insulating base material 1 are flush. . In addition, the polymerization drainage part 7 of the upper edge is
If the inclined shape is inclined to the left or right or either one, or if the wall surface is similarly inclined, and the overlapped covering portion 11 on the lower edge is also formed in a configuration corresponding to this, drainage is further improved. Become. In the heat insulating base material 1 described above, the polymerization drainage portion 6 extends along the right edge of the surface of the heat insulating base material 1.
However, the superposed drainage portion 6 at the side edge may be provided along the left side edge. In this case, the superimposed covering portion 10 is provided along the right side edge of the back surface of the base material 1.

Further, on the flat surface of the heat insulating base material 1, a large number of narrow grooves 14 extending downward toward the concave grooves 2 are formed in parallel. The narrow groove 14 has an underwater end connected to the concave groove 2, and the rainwater that reaches the heat insulating base material 1 flows into the concave groove 2 through the narrow groove 14, and The water flows down the downflow groove 4 in the inside and is quickly drained to the lower side of the water. The number of the concave grooves 2 provided in the heat insulating base material main body 1 may be one or more.
Is preferably formed separately on the left and right of each groove 2. The narrow groove 14 is a small groove for guiding rainwater dropped on the surface of the heat insulating base material 1 to flow down the water while keeping the surface along the same surface. The rainwater dropped on the heat insulating base material 1 in the state flows along the narrow groove 14 and is drained downward. As a result, the absolute amount of rainwater that has entered the heat insulating base material 1 from the junction between the heat insulating base materials 1 and flowing into the polymerization drainage parts 6 and 7 is limited. (Waterproofness) is improved. Furthermore, as a result, the space of the polymerization drainage portions 6 and 7 that easily become a heat transfer portion can be minimized, which is preferable in terms of heat insulation performance. Further, the cross-sectional form of the narrow groove 14 may be a continuous combination of a substantially U-shaped convex portion and a concave portion, or may be a small wavy or zigzag cross-sectional shape. Absent.
