Shows the cross-sectional structure of the intersection (cross-sectional structure taken along line 2-2 of FIG. 1). As shown in these figures, the lower end of a fixed gasket 28 on the upper floor side (corresponding to the "fixed gasket for vertical joints on the upper floor" in claim 1) and the fixed gasket 28 on the lower floor (claim 1) A metal frame body 68 for connecting the two is interposed between the upper end of the "standard gasket for vertical joints on the lower floor" described above). In detail,
As shown in FIGS. 6A and 6B, the frame body 68 includes a vertical wall 70 and a horizontal wall 72 bent from the upper end of the vertical wall 70. The vertical wall 70 is fixed to the side wall portion of the vertical frame 24 with a screw 74 in a state of being inclined at a predetermined angle. Therefore, in the fixed state, the horizontal wall 72 is inclined by a predetermined angle so as to have a downward slope from the indoor side to the outdoor side in a side view. The vertical wall 70 corresponds to the "one wall portion" in claim 3, and the horizontal wall 72 corresponds to the "other one wall portion".

A sheet 76 is adhered to the top surface 72A of the horizontal wall 72 with an adhesive tape (double-sided tape) 78, and an elastic body 80 made of solid rubber or sponge rubber is attached to the surface of the sheet 76. Are glued by. The elastic body 80 has a length up to the vicinity of the surface of the outer wall panel 22 on the outdoor side. Also, adhesive tape 7
The reference numeral 8 extends further to the outside than this, and is folded back and adhered to the vertical portion of the upper cover 50. The secondary gasket portion 34 of the fixed gasket 28 on the upper floor is abutted against the top surface 72A of the horizontal wall 72 via the elastic body 80. As a result, the fixed gasket 28 on the upper floor side
The lower end surface of the secondary gasket portion 34 located on the indoor side is closed.

On the other hand, on the bottom surface 72B of the horizontal wall 72, an elastic body 8 made of sponge rubber or the like and partially having a two-layer structure is used.
2 is glued. The elastic body 82 is made of sponge rubber or the like. The elastic body 82 elastically deforms when the frame body 68 is assembled, so that the upper end surfaces of the primary gasket portion 32 and the secondary gasket portion 34 of the fixed gasket 28 on the lower floor side are closed (sealed). The above-mentioned top surface 72A of the horizontal wall 72, the adhesive tape 7
8, the elastic body 80 corresponds to the "top surface portion" of claim 1,
The bottom surface 72B of the horizontal wall 72 and the elastic body 82 correspond to the "bottom surface".

Further, at the end portion on the vertical joint side of the adjacent barrel inserts 38, a barrel gap gasket 84 is arranged. The body end small gasket 84 includes a fitting portion 84A fitted to the longitudinal joint side end of the barrel 38, and a seal portion 84B integrally formed in an annular shape from the fitting portion 84A. The seal portion 84B of the body endless gasket 84 is vertically arranged along the barrel insert 38, and is integrally connected to the seal portion of the primary gasket portion 32 of the upper fixed gasket 28.

Further, the space portion 86 between the primary gasket portion 52 for the horizontal joint and the secondary gasket portion 48 described above.
(See FIG. 1) communicates with the outside through the opening formed in the lip portion of the primary gasket portion 52 described above. Therefore, the atmospheric pressure in the space 86 is equal to the external atmospheric pressure. Further, both ends of the space portion 86 in the horizontal joint are communicated with the space portion 88 between the primary gasket portion 32 and the secondary gasket portion 34 in the vertical joint. Therefore, the space 88
The atmospheric pressure of is equal to the atmospheric pressure (outside pressure) of the space 86. That is, in the present embodiment, an isobaric seal structure is configured.

The operation and effect of this embodiment will be described below. Describing along the process of building the unit house 10, first, the residential unit 12 on the lower floor is placed on the foundation.
Is installed. At this time, the fixed gasket 28 has already been assembled to the residential unit 12 in the factory. When the other residential unit 12 is installed adjacent to the one residential unit 12, the primary gasket portion of the fixed gasket 28 is formed on the vertical joint 18 formed by both the residential units 12 as shown in FIG. 32, the secondary gasket portion 34, and the lip portion 36 are arranged in pressure contact with each other.

Next, the frame body 68 is attached to the upper end portion (the portion corresponding to the intersecting portion) of the vertical joint 18 of the residential unit 12 on the lower floor side. Specifically, the vertical wall 70 of the frame body 68 is attached to the vertical frame 24 of the outer wall panel 22 with screws 74 in a state of being inclined at a predetermined angle.
At this time, the protruding portion of the sheet 76 is folded back and adhered to the vertical portion of the upper cover 50 by the adhesive tape 78. As a result, the elastic body 82 hermetically seals between the upper end portions of the primary gasket portion 32 and the secondary gasket portion 34 in the fixed gasket 28 on the lower floor side.

Next, the upper-floor residential unit 14 is sequentially installed on the upper end of the lower-floor residential unit 12. As a result, the lower end of the secondary gasket portion 34 of the fixed gasket 28 on the upper floor side is abutted against the top surface 72A of the horizontal wall 72 of the frame body 68 while being sealed by the elastic body 80. In this state, since the horizontal wall 72 of the frame body 68 is arranged in a state of being inclined by a predetermined angle, even if rainwater enters the space 88, the rainwater is discharged to the outside along the horizontal wall 72. It

Further, since the trunk unit 38 is attached to the upper living unit 14 in advance, when the upper living unit 14 is installed, the upper barrel 40 is installed.
The secondary gasket part 48 is pressed against the horizontal part of the upper cover 50, and the primary gasket part 5
2 is pressed against the vertical portion of the upper cover 50.

The procedure for assembling the barrel 38 is as follows. First, the tip of the fitting portion 40C of the upper barrel 40 is inserted into the recess 60 of the fitting receiving portion 42A of the lower barrel 42. At this time, the tapered surface 58 is formed on the tip of the protrusion 62 of the fitting receiving portion 42A and the tip of the fitting portion 40C.
Since 64 is formed, a large clearance is secured during assembly. When the fitting portion 40C is relatively inserted into the recess 60, the fitting receiving portion 42 is inserted into the step portion 56 of the fitting portion 40C.
Insertion is stopped by the contact of the tip end of the protruding portion 62 of A. Thereafter, by rotating the lower case insert 42 toward the upper case insert 40 side, the waterproof material 66 is compressed and deformed so that they are in close contact with each other, and finally the thick walled portion of the tip of the fitting receiving portion 42A is the upper case insert 40. The rotation angle is regulated by coming into contact with the back surface of the, and both are connected by the rivet 54.

As described above, the vertical joint 18 and the horizontal joint 20 are provided.
In the state in which the general portion and the crossing portion are sealed, the primary gasket portion 52 and the secondary gasket portion 48 for the horizontal joint are formed.
The space 86 between the space and the outside communicates with the outside. In addition, the space portion 86 and the space portion 88 between the primary gasket portion 32 for the vertical joint and the secondary gasket portion 34 are communicated with each other. As a result, an isobaric seal structure is established as a whole.

Here, in the present embodiment, by only interposing a single frame body 68 between the upper end surface of the fixed gasket 28 on the lower floor side and the lower end surface of the fixed gasket 28 on the upper floor side, the lower floor side is formed. The upper end surface of the fixed gasket 28 and the lower end surface of the fixed gasket 28 on the upper floor are sealed on the indoor side, and the horizontal wall 72 is arranged at a predetermined angle so that the drainage surface is secured. Therefore, the rainwater that has entered the indoor side can be reliably discharged to the outside by a simple operation.

Further, in this embodiment, the frame body 68 is used.
Since the vertical wall 70 is fixed to the upper end of the vertical frame 24 by the screw 74, the frame body 68 can be rigidly joined to the vertical frame 24. Therefore, the lower surface of the fixed gasket 28 on the upper floor side and the fixed gasket 28 on the lower floor side
The horizontal wall 72 can be held at a fixed position regardless of the position of the upper end surface of the. Therefore, the horizontal wall 7 of the frame body 68
The inclination accuracy of 2 can be improved. As a result, even if the positions of the lower end surface of the fixed gasket 28 on the upper floor side and the upper end surface of the fixed gasket 28 on the lower floor side vary, the clearance between the lower end surface and the upper end surface of the gasket 28 is considered. Only then, a stable airtight state and drainage performance can be obtained.

Further, since the elastic body 82 is arranged on the back surface of the horizontal wall 72, even when the upper surface of the fixed gasket 28 on the lower floor side is uneven due to a step in assembling or a rough surface at the time of cutting, By absorbing this with the elastic body 82, the horizontal wall 7
It is possible to prevent a gap from occurring between 2 and the upper end face, and to secure a stable airtight state.

Further, in the present embodiment, the seat 76 is provided on the top surface 72A of the horizontal wall 72 of the frame body 68, and the seat 76 is made to extend to the outdoor side more than the thickness of the outer wall panel 22. Since the extending portion is adhered to the upper end portion of the outer wall panel 22 with the adhesive tape 78, a continuous waterproof surface without a seam can be obtained from the secondary gasket portion 34 of the fixed gasket 28 to the surface of the outer wall panel 22. Therefore, it is possible to improve the drainability of rainwater that has entered the secondary gasket portion 34 side of the fixed gasket 28, and prevent rainwater from entering between the seat 76 and the outer wall panel 26 due to the head pressure difference. . further,
By using the sheet 76, it is possible to flexibly follow the step of the outer wall panel 22.

Further, in this embodiment, since the body end small gasket 84 is arranged at the end of the body insert 38 on the longitudinal joint side and is connected to the primary gasket portion 32 of the fixed gasket 28, the waterproof reliability is improved. A high space (space portion 86) is continuously ensured up to the inside of the barrel 38. As a result, it becomes possible to use the inside of the barrel 38 as an air guide path for equal pressure waterproofing. Therefore, high waterproofness can be secured. Further, according to the present embodiment, since the body end cap gaskets 84 are provided at the longitudinal joint side end portions of the body inserts 38 to connect the adjacent body inserts 38 to each other, the connecting member becomes unnecessary and It is possible to improve the appearance of the connecting portion between the matching barrels 38.

Further, in this embodiment, the barrel 38 is divided into a barrel upper portion 40 and a barrel lower portion 42 and they are fitted together to be integrated, and further, the fitting portion 40C and the fitting receiving portion 42A. Since the tapered surfaces 58 and 64 are provided on the
A relatively large clearance can be secured when fitting the upper part 40 of the body and the lower part 42 of the body. Therefore, the workability of assembling the barrel 38 can be improved. Further, since the barrel 38 is previously integrated in the factory and the barrel gap 38 is used to connect the barrels 38 to each other, connection work on site is not necessary.
Work scaffolding is not required, and it is possible to easily perform construction in dense areas where a sufficient gap cannot be secured between adjacent buildings.

Further, in the present embodiment, the barrel upper portion 40
And the lower part 42 of the body, the fitting portion 40C and the fitting receiving portion 42A
Since the connection portion and the rivet 54 are fixed at two points separated from each other, not only the attachment strength of the connection portion can be secured, but also an attachment angle error due to variations in component accuracy is unlikely to occur and breakage is less likely to occur. In addition, since the connecting portion of the fitting portion 40C and the fitting receiving portion 42A extends along the longitudinal direction of the barrel 38, even if the pitch of the rivets 54 is increased, it is sufficient for an external force (wind pressure or the like). Can withstand. Therefore, the number of rivets 54 is small, and a favorable appearance can be obtained.

Moreover, in the present embodiment, the body lower portion 42
Since the elastically deformable waterproof material 66 is disposed in the fitting receiving portion 42A, the waterproof property at the connecting portion between the upper case 40 and the lower case 42 can be improved. Further, the elastic restoring force of the waterproof material 66 causes the fitting portion 4 of the upper portion 40 of the girder.
Since it acts as a fitting force between 0C and the fitting receiving portion 42A of the trunk lower portion 42, the fitting state can be ensured.

Although the substantially L-shaped frame body 68 is used in the present embodiment, the present invention is not limited to this, and a connecting body having another structure can be used. For example, in the example shown in FIG. 8, a bottom wall 90 having a horizontal wall surface, a top wall 92 inclined by a predetermined angle with respect to the bottom wall 90, and these bottom walls 9 are provided.
0 and the bottom wall 90, a pair of side walls 94 and an intermediate wall 96
A block body 98 constituted by and is used instead of the frame body 68. The block body 98 is adhered to the upper end surface of the fixed gasket 28 on the lower floor side by the adhesive tape 78 adhered to the bottom surface of the bottom wall 90. As a result, the upper end surface of the fixed gasket 28 on the lower floor side is hermetically sealed. When the block body 98 is used, the upper end of the fixed gasket 28 on the lower floor side is set lower by the height of the block body 98. Further, the seat 76 and the elastic body 80 are arranged on the top surface of the top wall 92, and the lower end surface of the fixed gasket 28 on the upper floor side is abutted against the seat 76 and the elastic body 80. It should be noted that this embodiment corresponds to an embodiment of the present invention according to claim 2. Further, in the relationship with the invention according to claim 1, the top wall 92, the sheet 76, and the elastic body 80 correspond to the “top surface portion”, and the bottom wall 90 corresponds to the “bottom surface portion”.

Also in this example, the same effect as that of the above-described embodiment can be obtained, and since the top wall 92 and the bottom wall 90 are connected by the pair of side walls 94 and the intermediate wall 96,
The structure can be stabilized. Further, the lower end surface of the fixed gasket 28 on the upper floor side and the fixed gasket 2 on the lower floor side
Even when a large variation occurs in the distance dimension from the upper end surface of 8, the side wall 94 and the intermediate wall 96 can be elastically deformed and absorbed. The bottom wall 90 and the top wall 92 may be connected to each other by only the pair of side walls 94, only the intermediate wall 96, or four or more walls.

In the above-mentioned example, the length of the seat 76 is set to the length of the surface of the outer wall panel 22 on the outdoor side. However, as shown in FIG.
