It was developed for the purpose of completely water-tightening the joint part of
Packing materials 158 and 1 represented by the watertight structure 150 and the like
This is an improvement over the one using 68. In this watertight structure 170, packing materials 177 and 178 are provided between the upper and lower members 172 and 173 on the indoor side and abutted against each other, and a gap 176 is formed on the outdoor side to form a gap 17 with the packing material 178 and the like.
A large space 174 is formed between the six. According to the watertight structure 170, the space 174 has the same atmospheric pressure as the external pressure due to the gap 176, and rainwater does not enter the space 174 through the gap 176 due to the pressure difference. Further, rainwater that has entered through the gap 176 with kinetic energy also enters the space 174, but the packing material 178 and the like cannot reach these because it is at a high position that cannot be seen through the gap 176. Further, the rainwater that has entered the space 174 is smoothly discharged from the gap 176 due to gravity because the interior of the space 174 has the same atmospheric pressure as the external pressure. As a result, the water that has entered up to the height of the packing material 178 and the like in the space 174 is not accumulated, and as a result, complete water tightness is achieved.

The operation will be performed in the embodiment described below, but for the principle thereof, refer to, for example, Japanese Patent Publication No. 9-508073. In general, when welding members made of aluminum alloys by arc welding such as MIG, inventions have been proposed in which various welding conditions are devised in order to obtain good welding quality and excellent sealing performance. 8-197255, JP-A-9-103884). But these are

る。Therefore, in recent years, attention has been given to the friction stir welding, which is capable of joining metal materials more easily than arc welding. As shown in FIGS. 12 (A) and 12 (a), this friction stir welding rotates along the abutting surface between a pair of aluminum alloy flat plates 180, 181 whose edges are abutted and restrained. This is performed by moving the tool 182 while pressing it. The tool 182 is made of a material having a hardness and a softening temperature higher than that of a material to be joined, and includes a rotating cylindrical body 184, a surface restraining portion 186 which is a concave bottom surface thereof, and a friction pin 188 coaxially hanging from the center thereof. Then, the tool 182 is horizontally tilted slightly along the abutting surface.
It is moved in the (left) direction and a vertical pushing force is applied. A screw-shaped friction stirrer blade (not shown) along the horizontal direction is formed on the peripheral surface of the friction pin 188.

It is heated by frictional heat to be plasticized, and is fluidized in the horizontal and vertical directions between the plates 180 and 181 with the abutting surfaces sandwiched therebetween. Further, the surface restraint 186 suppresses the vertical flow of the fluidized aluminum and stirs the fluidized aluminum by the friction pin 188. As a result, as shown in FIGS. 12 (B) and 12 (C), the aluminum is solidified in the solid state, and the stirring section 18 is solidified.
It becomes 9. In addition, the surface of the stirring portion 189 becomes a joining line 190 which is flat and has a constant width. Therefore, unlike the conventional arc welding, there is no raised welding beat, and post-processing becomes easy.

径の約2〜3倍で良い。Since the conventionally considered application of such friction stir welding is an application requiring a joining strength in place of MIG welding or the like, 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 restraint portion was 6 to 25 mm, which were relatively large. Further, in this case, the rotation speed of the tool 182 is 500 to 15000 rpm, and the feed speed is 0.
Pressing force applied to the tool 182 at 05-2 m / min: 1
It was performed at kN to 20 kN. In the present invention, the watertightness is the object and the bonding strength is not the object. Therefore, the depth and width of the bonding line may be extremely small. Therefore, in the tool used for friction stir welding, the length of the friction portion of the friction pin is 3 mm or less and its 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 its range is 0.5 mm. The requirement is to be ~ 3.0 mm. The diameter of the surface restraining portion may be about 2 to 3 times the outer diameter of the friction portion.

The pressing force applied to the above tool can be performed at about 10 N to 1000 N at 0000 rpm and a feed rate of 0.02 to 2 m / min. The number of rotations is increased because the friction pin has a small outer diameter and is required to obtain the amount of heat required for softening aluminum. Further, the reason why the pushing force is small is that the outer diameter and the pushing depth of the friction pin become small. This makes it possible to make a small handy device, and it becomes a portable joining device that can be used at a construction site or the like. Further, in order to obtain the rotational speed, it can be realized by using, for example, a turbine motor using compressed air (eg, a dental drill) in addition to a normal electric motor. If the size of the friction pin is smaller than the above, high precision is required for processing, the dimensional precision of the pin material itself is considerably required, and it is not practical, and the friction stirrer blade formed on the peripheral surface is also sufficiently formed. Becomes difficult. Further, if the size is larger than the above size, a large force is required for the tool as described above, the apparatus becomes large in size, and the size of the pin material has to be increased, which is not practical.

多いためである。First, as shown in FIG. 1 (A), the ridges 4, 4 are formed so that the end portions 8 of the extruded shape members 2, 2 adjacent in the longitudinal direction are brought into contact with each other to form a butt portion 9. The shape members 2 and 2 are fixed to a structural member such as a column (not shown) by using screws 4 or the like by using the screw 4.
In this state, friction stir welding described below with reference to FIG. 2 is performed along the upper surface (front surface) side of the butted portion 9 between the extruded shape members 2 and 2. Then, as shown in FIGS. 1B and 1C, a shallow joining line W having a depth corresponding to the length of the friction pin is formed across the respective end portions 8 and 8. This joining line W is formed by the aluminum forming each end 8 being fluidized in a solid state and then solidified, so that the adjacent extruded shape members 2 and 2 are metallically joined along the abutting portion 9. And the reliable and stable watertight structure 1 can be obtained. Moreover, as shown in FIG. 1 (C), since the surface of the joining line W is flat, there is no protruding portion and post-processing is hardly required. The joining line W is formed along the front surface side of the abutting portion 9 because it is necessary to perform watertight construction after attaching the extruded shape members 2 and 2 at predetermined positions in FIG. 1 (A). This is because there are many cases.

The tool 10 is made of a material having a hardness and a softening temperature higher than that of the shape member 2, and is coaxial with the center of the rotary cylinder 12 and the surface restraining portion 14 having an outer diameter of 4 mm which is a bottom surface of the rotary cylinder 12 and is gently curved. It consists of a hanging friction pin 16. The friction pin 16 has an outer diameter of 1.8 mm and a length of 1.5.
A cylindrical mm-shaped cylindrical body having a screw-shaped small friction stirrer not shown is formed on the outer peripheral surface thereof. Then, as shown in the drawing, the central axes of the cylindrical body 12 and the friction pin 16 are set to the shape members 2
The tool 10 is rotated by a motor (not shown) and lowered toward the abutting portion 9 in a state in which the end portions 8 and 8 are slightly inclined from the right angle. The rotation speed of the tool 10 is appropriately selected within the range of 3000 to 30000 rpm.

きる。According to the watertight structure 1 obtained by shallowly joining a plurality of extruded shape members 2 with the above-described joining line W, no prior processing is required, and the shape members 2 are simply butted and restrained to form a metallic structure. Since a unique joint is formed along the entire length of the abutting portion 9,
Water tightness can be reliably and stably imparted to a flat wall / floor / ceiling surface over the long term. Moreover, since the surface Wa of the joining line W is flat, almost no post-processing such as grinding is required. It should be noted that a shape member obtained by bending the middle of the flat plate portion 3 of the shape member 2 at a right angle or a shape member having a substantially cross section in advance is interposed between a plurality of watertight structures 1 and 1 and joined in the same manner as above. By joining along the line W, it is possible to form a three-dimensional watertight structure in which the wall surface and the floor surface and / or the ceiling surface are continuously sealed.
