A watertight structure of a wall surface or a roof surface, wherein the joining line is formed by friction stir welding using a tool including a friction pin having a friction portion of 0 mm and an outer diameter of 0.5 to 3.0 mm and a surface suppressing portion (claim Item 3) is also included. According to this, it is possible to more reliably form the watertight structure between members having a flat surface and a shallow bonding line. The length of the friction portion is set to 3.0 mm or less because watertight construction is generally performed at an assembly site or a construction site, and is carried out by a friction stir welding apparatus including the tool which is easy to transport and operate. This is to make it possible. The minimum length is set to at least 0.5 mm in order to perform reliable joining and prevent poor watertightness. Furthermore, the reason why the minimum outer diameter of the friction portion is 0.5 mm is because the friction pin corresponds to the minimum outer diameter required for strength,
The maximum outer diameter is 3.0 from the point of transportation and operability of the above-mentioned joining device.
mm. That is, in the friction stir welding, the force for pressing the friction pin is a large factor. However, as the pressing force increases, the entire bonding apparatus becomes large, and is not suitable for use in an assembly site or the like. . The surface suppressing portion has a diameter that is two to three times the outer diameter of the friction portion.

A watertight structure of a wall surface or a roof surface, wherein watertightness is provided between the plurality of construction panels by forming the joining line.
(Claim 5) is also included. According to this, various panels such as a sandwich panel in which various core materials or the like are filled between a pair of plate members can be joined to each other while maintaining watertightness through an extruded shape member, and a wide range of wall surfaces and roof surfaces can be used.

In general, when aluminum alloy members are welded to each other by arc welding such as MIG, an invention has been proposed in which welding conditions are variously devised in order to obtain good welding quality and excellent sealing performance (Japanese Patent Application Laid-Open No. HEI 9-134572). 8-197255, JP-A-9
-103884). However, since these require a welding wire or the like separately and must be performed strictly under welding conditions, the management of welding becomes complicated, and
There is a problem that post-processing for grinding and removing the top part of the formed weld bead is sometimes required.

形成されている。Therefore, in recent years, the above-mentioned friction stir welding, which can easily join metal materials as compared with arc welding, has been receiving attention. As shown in FIGS. 9A and 9A, this friction stir welding is performed by rotating along a butting surface between a pair of aluminum alloy flat plates 180 and 181 whose edges are butted and constrained to each other. The tool 182 is moved while being pressed. The tool 182 is made of a material having a higher hardness and softening temperature than the material to be joined.
And a surface suppressing portion 186 which is a concave bottom surface thereof, and a friction pin 188 which coaxially hangs from the center thereof. Then, the tool 182 is moved in the horizontal (left) direction while being slightly inclined along the butting surface, and a vertical pushing force is applied. In addition, a screw-shaped friction stirrer blade (not shown) is formed on the peripheral surface of the friction pin 188 along a horizontal direction (not shown).

While being plasticized by heating by frictional heat, it is fluidized in the horizontal and vertical directions between the plates 180 and 181 with the abutting surface therebetween. In addition, the above-mentioned surface suppressing portion 186
The fluidized aluminum is prevented from flowing in the vertical direction, and the fluidized aluminum is stirred by the friction pins 188. As a result, as shown in FIGS. 9 (B) and 9 (C), the aluminum was solidified in a solid state and the stirring section 1
89. In addition, the surface of the stirring section 189 becomes a bonding line 190 having a flat and constant width. Therefore, there is no raised welding beat like conventional arc welding,
Post-processing becomes easier.

外径の約２〜３倍で良い。Conventionally, the application of such friction stir welding is an application requiring joining strength in place of MIG welding or the like. Therefore, the length of the friction portion of the friction pin is usually 3 to 15 m.
m, the diameter was 3 to 10 mm, and the diameter of the surface suppressing portion was 6 to 25 mm, which was relatively large. In this case, the rotation speed of the tool 182 is 500 to 15000 rpm, and the feed speed is 0.
At a speed of 0.5 to 2 m / min, the pushing force applied to the tool 182 is 1
kN to 20 kN. In the present invention, since the purpose is watertightness and not the bonding strength, the depth and width of the bonding line need only be extremely small. Therefore, the length of the friction portion of the friction pin in the tool used for friction stir welding is 3 mm or less and the range is about 0.5 mm to 3.0 mm, and the outer diameter of the friction portion is 0.5 mm or more and the range is 0.5 mm or more.

000 rpm, feed rate 0.02 to 2 m / min, and the pushing force applied to the tool is about 10N to 1000N.
As described above, the number of rotations was increased because the outer diameter of the friction pin was small, so that it was necessary to obtain the heating amount necessary for softening aluminum. The reason why the pushing force is small is that the outer diameter and the pushing depth of the friction pin become small. As a result, a small-sized handy device can be obtained, and a portable joining device can be used at a construction site or the like. Furthermore, in order to obtain the above-mentioned number of rotations, besides a normal electric motor, for example, a turbine motor using compressed air (eg, a dental drill) can be used. If the size of the friction pin is smaller than the above, high precision is required for processing, the dimensional accuracy of the pin material itself is considerably required, which is not practical, and the friction stirrers formed on the peripheral surface are also sufficiently formed. It becomes difficult to do. On the other hand, if the size is larger than the above-mentioned size, a large force is required for the tool as described above, and the device becomes large-sized, and the size of the pin material must be increased, which is not practical.

In this state, the friction stir welding described below with reference to FIG. 2 is performed along the upper surface (front surface) of the butted portion 9 between the extruded members 2. Then, as shown in FIGS. 1B and 1C, a joining line W having a depth corresponding to the length of the friction pin is formed across the end portions 8, 8. Since the joining line W is formed by solidifying the aluminum forming each end 8 after fluidizing in a solid state, the adjacent extruded sections 2 and 2 are metallically joined along the butt 9. In addition, a reliable and stable watertight structure 1 can be obtained. In addition, as shown in FIG. 1C, the surface of the joining line W is flat, so that there is no protrusion and almost no post-processing is required. The reason why the joining line W is formed along the surface side of the butted portion 9 is that watertight construction is required after each of the extruded members 2 and 2 is attached to a predetermined position in FIG. This is because there are many cases.

This feed speed is appropriately selected within a range of 0.05 to 2 meters / minute. As the tool 10 rotates and moves, the aluminum forming the vicinity of the butting portion 9 of each end 8 is heated and plasticized by the friction pin 16 and the left and right profiles are sandwiched by the butting portion 9. It is fluidized in the horizontal and vertical directions between the two. In addition, the fluidized aluminum is given a certain pressure against the flow in the vertical direction (surface direction) by the above-mentioned restraining portion 14 and prevents the aluminum from scattering outside from near the surface of each end 8 to be joined.

The joining line W has a substantially inverted triangular cross section. As shown in FIG. 2C, the surface of the joining line W becomes a flat surface Wa continuous along the abutting portion 9, although the surface suppressing portion 14 slightly dents the portion corresponding to the width of the diameter. In addition, no air is formed inside the joining line W due to the presence of the suppressing portion 14, so that no air hole is formed.

造にすることもできる。According to the watertight structure 1 such as a wall surface obtained by joining a plurality of extruded sections 2 shallowly with the above-mentioned joining line W, the sections 2 are butted and restrained without any prior processing. Since only a metallic joint is formed along the entire length of the butted portion 9, it is possible to reliably and stably impart watertightness to the flat walls, floors and ceiling surfaces over a long period of time. . Moreover, since the surface Wa of the joining line W is flat, post-processing such as grinding is almost unnecessary. It is to be noted that a shape material obtained by bending the middle of the flat plate portion 3 of the shape material 2 at a right angle or a shape material whose entire cross section is substantially in advance is interposed between the plurality of watertight structures 1 and joined in the same manner as described above. By joining with the line W, a three-dimensional watertight structure in which the wall surface and the floor surface and / or the ceiling surface are continuously sealed can be obtained.
