Description

  The present invention relates to a water blocking structure of an outer wall of a building and a balcony waist wall.

  In the outer wall of a building, an outer wall panel provided with various patterns having a concave portion and a convex portion is often applied, and as such an outer wall panel, for example, a ceramic siding material or a metal siding material And panels formed therefrom. As the depth of the recess, i.e., the depth to the bottom of the handle increases, the appearance design is enhanced, and therefore, it is possible to produce a digging outer wall panel in which the depth of the recess is deeper than that of the conventional outer wall panel. It is For example, when the depth to the bottom of the handle is about 9 mm and the depth is about 12 mm and about 3 mm, the appearance design of the outer wall panel is remarkably excellent.

  By the way, in a multi-storey detached house or apartment, a balcony is often installed on the second floor or more. The balcony is constructed in such a manner that a balcony floor beam is projected from the outer wall panel and the balcony floor beam supports the balcony waist wall after the construction of the outer wall panel is finished at the site. Inside the balcony waist wall, a balcony floor is constructed so as to be supported by the balcony floor beam. A balcony base plate is attached below the balcony floor beams, and the balcony floor beams are isolated from the outside. If there is a gap between the end face of the constructed balcony waist wall and the outer wall panel, rain water or the like may enter the balcony floor beam or the like through the gap. If the balcony floor beam is wood, it will be corroded by the entering rainwater, and if the balcony floor beam is a shaped steel such as H-shaped steel, the coating on the shaped steel surface will be degraded by the rainwater, and the steel will be exposed and corroded It can be achieved. In addition, when the balcony waist wall is internally provided with a metal waist wall frame, rainwater infiltrates into the inner waist wall frame, and the oxide film on the surface of the waist wall frame may be destroyed, leading to corrosion.

  Therefore, between the end face of the balcony waist wall and the outer wall panel, it is necessary to take measures to prevent water from entering the structure of the balcony. In particular, in the case of the outer wall panel having the above-described concave and convex portions, since a gap is easily formed between the balcony waist wall and the outer wall panel, water blocking measures become even more essential and important. Thus, as a water stop measure between the outer wall panel having the recess and the balcony waist wall, conventionally, in the surface of the outer wall panel to which the end face of the balcony waist wall is attached, the recess is eliminated to form a flat mounting surface Such scraping is performed, and the method of attaching the end face of the balcony waist wall to a flat mounting surface formed is applied in some cases. However, this method has the problems that it takes time and labor to scrape the surface of the outer wall panel, and there is a possibility that the outer wall panel may be damaged to some extent during the scraping.

  On the other hand, after inserting an elongated dry type waterproofing material into the recess in the vertical joint area of the outer wall panel and bringing the end face of the balcony waist wall into contact with this vertical joint area, the metal material provided with the dry waterproofing material is a balcony A waterproof method and a waterproof structure have been proposed which are attached at the top end of the lumbar wall and by pressing and compressing a dry water blocking material into the outer wall panel (see, for example, Patent Document 1).

JP, 2005-256508, A

  However, the waterproof structure described in Patent Document 1 is disclosed herein because it is not intended to stop water between the patterned outer wall panel having the concave portion and the convex portion and the end face of the balcony waist wall. The long dry joint water blocking material can not be introduced into the many recesses provided in the outer wall panel, and an effective water blocking structure can not be formed.

  The present invention has been made in view of the above problems, and it is an outer wall that can achieve high water-resistance while eliminating the need for scraping the surface of the outer wall panel between the outer wall panel having many recesses and the end face of the balcony waist wall. And the purpose of the balcony is to provide a water barrier structure of the waist wall.

In order to achieve the above object, one aspect of the water blocking structure of the outer wall and the balcony waist wall according to the present invention is the attachment below the balcony waist wall to the balcony floor beam extending from the outer wall provided with the recess and the projection. A water blocking structure of an outer wall and a balcony waist wall which is formed between an end face of the balcony waist wall and the outer wall in a state in which the part is fixed,
Between the end face and the outer wall, a dry water blocking material extending in the width direction of the end face is interposed in a compressed state,
The dry water blocking material is
It consists of a compressible elastic body,
A pedestal extending in the width direction of the end face and attached to the end face, a plurality of thin rods extending from the side surface on the outer wall side of the base, and the same length as the thin rods extending from the side surface of the base Upper and lower plates disposed above and below the plurality of thin rods;
A pressing plate having a relatively low compressibility and a high rigidity is attached to the upper surfaces of the pedestal and the upper plate, as compared with the dry water blocking material.

  According to this aspect, the plurality of thin rods of the dry type water blocking material having compressibility enter into the recess and the upper upper plate presses the plurality of thin rods from above and the upper plate is above By holding down the relatively high-rigidity holding plate, a plurality of thin rods can be sufficiently inserted into the recess to obtain high water barrier property. In addition, high water-repellency can also be obtained by abutted, for example, the front end of the pressing plate in a compressed state on the surface of the outer wall panel.

Further, in another aspect of the water blocking structure of the outer wall and the balcony waist wall according to the present invention, the pressing plate is characterized by not projecting toward the outer wall side than the upper plate.
According to this aspect, for example, in a mounting method in which the balcony waist wall in a state of being suspended by a heavy machine is suspended and seated while pressing against the outer wall panel, the pressing plate located above is relatively high rigidity outer wall panel It is possible to eliminate that the function of the pressing plate which presses the plurality of thin rods downward can be prevented.

Further, another aspect of the water blocking structure of the outer wall and the balcony waist wall according to the present invention is characterized in that a plurality of combinations of the pressing plate and the dry water blocking material are arranged in the upper and lower direction. .
According to this aspect, for example, the lower end of the holding plate is sandwiched between the dry water stopping materials located above and below, so that, for example, the front end of the holding plate firmly abuts on the outer wall panel, High water barrier properties can be obtained.

Further, another aspect of the water blocking structure of the outer wall and the balcony waist wall according to the present invention is characterized in that the pressing plate and the dry water blocking material are disposed in the vicinity of the mounting portion.
According to this aspect, since the attachment force acting on the balcony waist wall attached to the balcony floor beam can be effectively applied to the pressing plate and the dry water blocking material in the vicinity of the attachment portion, the outer wall panel On the other hand, the pressing plate and the dry water blocking material can be sufficiently pressed and compressed.

In the other aspect of the water blocking structure of the outer wall and the balcony waist wall according to the present invention, another dry water blocking material extending in the longitudinal direction is disposed at the left and right positions of the end face below the dry water blocking material. Has been
The other dry water stop material is made of a compressible elastic body, and has at least a pedestal, and a plurality of thin rods projecting from the side surface on the outer wall side of the pedestal. .
According to this aspect, even when the moisture passes through the holding plate extending in the width direction of the end face of the balcony waist wall and the dry water blocking material passes downward, the other extending longitudinally in the left and right positions It is possible to suppress the inflow of moisture to the central side of the balcony waist wall with a dry water blocking material, and thus to inhibit the infiltration of moisture into the central side of the balcony waist wall structure. Can.

Further, another aspect of the water blocking structure of the outer wall and the balcony waist wall according to the present invention is characterized in that the elastic body is a closed cell structure.
According to this aspect, since the elastic body is formed of the closed cell structure, it is possible to stop the water even with a small compression rate.

  As can be understood from the above description, according to the water blocking structure of the outer wall and the balcony waist wall of the present invention, it is possible to provide a water blocking structure having high water blocking performance while eliminating the need for scraping the surface of the outer wall panel.

In the present specification and the drawings, substantially the same components are denoted by the same reference numerals and redundant description will be omitted.

First Embodiment
<Summary of house>
First, an example of a house to which the water stopping structure of the outer wall and the balcony waist wall according to each embodiment is applied will be described using FIG. 1. The building H shown in FIG. 1 is a light-weight steel 2-story house. The outer wall panel (outer wall) 1A is formed of a siding material. Examples of the siding material include ceramic-based siding, metal-based siding made of aluminum and steel plates, wood-based siding obtained by processing natural wood, and resin-based siding made of vinyl chloride resin and the like. The outer wall panel 1A has a pattern of various asperities on its surface. Although an enlarged view of the outer wall panel 1A is shown in FIG. 1, as shown in the drawing, it is disposed at a predetermined interval in the vertical direction and a plurality of vertical recesses 1b disposed at a predetermined interval in the horizontal direction. A plurality of horizontal recesses 1a are formed, and rectangular projections are formed by the vertical recesses 1b and the horizontal recesses 1a. The vertical recess 1b and the horizontal recess 1a are both deep for example about 12 mm in depth to the bottom of the handle, and the exterior design of the house H is enhanced by the deep wall panel 1A. The outer wall panel 1A has its upper and lower end surfaces scraped by half of its thickness to form a fruit, and the outer wall panels 1A adjacent to each other in the upper and lower portions are joined together to form a plurality of outer wall panels 1A in a row Is attached. And there is a vertical joint 2 between each row, and this vertical joint 2 is formed of a joint joiner (not shown) and a dry water stopping material such as a gasket. In addition, the vertical joint 2 may be equipped with a wet waterproof material.

  The house H shown in FIG. 1 is provided with a balcony 4 on the second floor, and can freely enter and exit from the discharge window 3. A water blocking structure according to each embodiment described in detail below is formed between the balcony waist wall forming the balcony 4 and the outer wall panel 1A.

<Adhesive body of dry water blocking material and pressing plate>
Next, with reference to FIG. 2, an adhesive body of a dry water blocking material and a pressing plate which forms a water blocking structure of the outer wall and the balcony waist wall according to each embodiment will be described. FIG. 2 is a perspective view of an example of a bonded body of a dry water blocking material and a pressing plate. The dry water blocking material 10 is made of a compressible elastic body, and the base 11, the plurality of thin rods 14 protruding from the side of the base 11, and the upper plate 12 sandwiching the bundle of the plurality of thin rods 14 vertically And a lower plate 13. The plurality of thin rods 14 are formed by a large number of slits in the vertical direction and the horizontal direction. For example, for a cubic elastic body having overall dimensions of height t, overhang length s, and width v, the overhang length s1 of the pedestal 11 is secured, and the height t1 of the upper plate 12 and the lower plate 13 is secured By forming a large number of slits in the vertical direction and the horizontal direction, it is possible to manufacture the illustrated dry water blocking material 10. For example, the pedestal 11, the upper plate 12, the lower plate 13 and the large number of thin rods 14 may be separately manufactured and bonded to each other to manufacture the dry water-stop material 10 of the illustrated example.

  The dry water blocking material 10 which is a compressible elastic body is made of a closed cell structure. The closed cell structure is, for example, a sponge having a structure in which cells are independently arranged, and is a material that does not allow gas or liquid to pass through like an open cell structure. More specifically, the dry water stop material 10 can be manufactured from EPDM rubber (ethylene propylene rubber), polyethylene rubber, or the like. As will be described later, the dry water blocking material 10 is pressed against the outer wall panel in a state of being adhered or the like to the end face of the balcony waist wall, and is suspended so as to slide the outer wall panel surface in this pressed state. Is exposed to the method of construction where it is seated on the balcony floor beam. In this construction method, the dry water blocking material 10 is not damaged when sliding on the outer wall panel surface in the pressed state, and the plurality of thin rods 14 are firmly fixed in the recess of the outer wall panel at the sitting position of the balcony waist wall. It is necessary to be able to get into, with deformation performance and rigidity, and wear resistance etc. Therefore, a material capable of imparting such performance is used for manufacturing the dry water-stop material 10, and the size and shape of each part of the dry water-stop material 10 are set.

  In the dry water-stopping material 10, the upper plate 12 and the lower plate 13 sandwich the bundle of many thin rods 14 so that the large number of thin rods 14 are prevented from being significantly warped upward in the above construction method, As a result, a large number of thin rods 14 can be inserted into the horizontal recess 1a and the vertical recess 1b of the outer wall panel 1A. Further, the large number of thin rods 14 can be easily deformed when pressed and can enter the vertical recess 1 b and the horizontal recess 1 a, and retain the water inside the large number of thin rods 14, so that the water is removed with time. Can evaporate and dissipate.

  As an example of the dimensions of the dry water-stopping material 10, s1 of 10 mm, s2 of 20 mm, s of 30 mm, t1 of 5 mm, t2 of 20 mm, t3 of 5 mm, t of 30 mm, and v of about 100 mm. In addition, the width | variety v of the dry water stop material 10 respond | corresponds to the length of the width direction of the end surface of a balcony waist wall, and is set according to the width | variety of this end surface.

  In the above construction method, for example, the dry water-stopping material 10 having an extension length s of 30 mm is pressed against the outer wall panel 1A and compressed, and slides on the surface of the outer wall panel 1A in a state where the extension length is about 12 mm. It is hung down.

  On the other hand, the presser plate 20 bonded to the upper surface of the dry water-stopping material 10 is a member having a relatively smaller compressibility than the dry water-stopping material 10, and thus a high rigidity. For example, when the dry water-stopping material 10 is made of EPDM rubber sponge, the pressing plate 20 can be made of PP resin (polypropylene), PE resin (polyethylene) or the like.

  The upper plate 12 of the upper plate 12 which suppresses the warping of the bundle of many thin rods 14 in the above-mentioned construction method by the relatively high rigidity holding plate 20 being adhered to the upper surface of the dry water blocking material 10 Warpage can be suppressed. As a result, a large number of thin rods 14 can be inserted into the horizontal recess 1a and the vertical recess 1b, and a high water barrier property can be obtained. In addition, by the pressing plate 20 itself also in contact with the surface of the outer wall panel 1A, it is possible to obtain a still higher water barrier property.

  Further, although the pressing plate 20 is bonded to the upper surface of the pedestal 11 of the dry water-stopping material 10 and the upper plate 12, the protruding length is smaller than that of the upper plate 12. By this, in the case of the said construction method, when the press plate 20 is excessively pressed with respect to the outer wall panel 1A and it slides down, it can suppress that the press plate 20 warps upwards. Furthermore, in the process in which the relatively high-rigidity pressing plate 20 is slid down in a state of being compressed on the surface of the outer wall panel 1A, the pressing plate 20 excessively presses the outer wall panel 1A and damages the surface of the outer wall panel 1A. Can also be suppressed.

  As an example of the dimensions of the pressing plate 20, s3 can be set to 20 mm, t4 to 0.2 mm, and v to about 100 mm (the same dimensions as the dry water-stopping material 10). The pressure plate 20 is adhered to the pedestal 11 of the dry water-stopping material 10 and the upper surface of the upper plate 12 through an adhesive or an adhesive tape.

  In addition, regarding the pressing plate 20 having a projecting length smaller than the bundle of the upper plate 12 and the large number of thin rods 14, the illustrated example shows the projecting length of the bundle of the upper plate 12 and the large number of thin rods 14 from the pedestal 11. While the length of (s2) is 20 mm, the length of the region above the upper plate 12 and the bundle of the large number of thin rods 14 in the pressing plate 20 is 10 mm, and thus the overhanging length of the pressing plate 20 The length is 10 mm short. With regard to how short the overhanging length of the pressing plate 20 is with respect to the overhanging length (s2) of the bundle of the upper plate 12 and the large number of thin rods 14, the range of 5 mm to 15 mm when s2 is set to 20 mm It is preferable to set them short. That is, in this case, the projecting length of the pressing plate 20 is in the range of 5 mm to 15 mm, and in the length range of 1/4 to 3/4 of s2. When the overhanging length of the pressing plate 20 is less than 1⁄4 of s2, the pressing effect by the pressing plate 20 becomes insufficient. On the other hand, when the overhanging length of the pressing plate 20 exceeds 3/4 of s2, the above construction method, that is, in the construction to be suspended to the sitting position so as to slide the outer wall panel surface in a state of being pressed against the outer wall panel In addition, the pressing plate 20 is excessively pressed against the outer wall panel to make the bonded body of the dry water blocking material 10 and the pressing plate 20 less slippery.

<Waterstop structure of outer wall and balcony waist wall>
Next, the water blocking structure of the outer wall and the balcony waist wall according to the first embodiment will be described together with a construction method for seating the balcony waist wall on the balcony floor beam. FIG. 3 is a perspective view showing a balcony waist wall and a balcony floor beam before the water blocking structure of the outer wall and the balcony waist wall according to the first embodiment is formed. The balcony waist wall 40 includes a metal waist wall frame 41 having a flat track shape in the form of a horizontally long track, and an outer wall panel 43 attached to one of two wide side surfaces of the waist wall frame 41 via a base frame 42. And an inner wall panel 44 attached via the base frame 42 to the other of the wide side surfaces. The inner wall panel 44 is a panel facing the inner side of the balcony, and the material is, for example, the same as that of the outer wall panel 1A, and on the surface thereof, a plurality of juxtaposed spaced apart in the same manner as the outer wall panel 1A. It has a vertical recess 44a and a horizontal recess 44b. The outer wall panel 43 is a panel facing the outside of the balcony and, like the inner wall panel 44, the material is, for example, the same as the outer wall panel 1A, and on the surface thereof, like the outer wall panel 1A, a predetermined distance is provided. It has a plurality of vertical recesses 43a and horizontal recesses 43b arranged in parallel.

  The balcony waist wall 40 has, in its lower part, a recessed area without the inner wall panel 44 and the inner side of the waist wall frame 41, and only the outer wall panel 43 and the waist wall frame plate on the outer wall panel 43 side It extends to the lower side. Then, two metal plates 45 in which bolt holes 45a are opened are connected by welding to the surface of the inside exposed waist wall frame plate at intervals. In addition. The method of forming the metal plate 45 is not limited to the illustrated example, and may be formed by cutting and bending the waist wall frame plate by 90 degrees, or may be formed by other embossing or the like. Good.

  On the other hand, a balcony floor beam 46 projects from the outer wall of the housing (not shown). The balcony floor beam 46 is made of, for example, an H-shaped steel, and is connected to a beam made of an H-shaped steel or the like between steel floors of a house, a steel pipe column, or the like. On the upper surface of the upper flange of the balcony floor beam 46, two fixing angles 47 in which bolt holes 47a are opened are attached by welding at positions just sandwiching the two metal plates 45 of the balcony waist wall 40. . The balcony waist wall 40 is hung down and seated so that the metal plate 45 is sandwiched between the two fixing angles 47, and the bolt hole 45 a of the corresponding metal plate 45 and the bolt hole 47 a of the fixing angle 47 are placed. By inserting a bolt (not shown), attachment of the balcony waist wall 40 to the balcony floor beam 46 is performed. In addition, the balcony waist wall 40 which forms a water blocking structure between the outer wall panel 1A also exists on the other side across the balcony space, and the front waist wall is attached to the front of these two balcony waist walls 40 A flat-panel-like balcony waist wall is formed.

  The bonded body of the dry water stop material 10 and the pressing plate 20 is a pressing plate at a lower position of the end face 41a on the outer wall panel 1A side of the waist wall frame forming the balcony waist wall 40, that is, directly above the depressed area. 20 is attached by adhesion or the like so as to extend in the width direction of the end face 41a in a posture where the face 20 is disposed upward.

  Before describing the water blocking structure according to the first embodiment, a method of attaching the balcony waist wall 40 to the balcony floor beam 46 will be described with reference to FIG. 4. As shown in FIG. 4A, a worker (not shown) pushes the balcony waist wall 40 into the outer wall panel 1A side while the balcony waist wall 40 is suspended by a crane (not shown). For example, as described above, the dry water-stopping material 10 having an extension length s of 30 mm is pushed in to compress the dry water-stopping material 10 and the pressing plate 20, and as shown in FIG. The pressing force is applied until the overhang length u of the frame is about 12 mm. For example, the position where the dry water blocking material 10 has an overhang length of 12 mm (the distance between the balcony waist wall 40 and the outer wall panel 1A) is when the balcony waist wall 40 is hung down and seated on the balcony floor beam 46 As described above, the two metal plates 45 of the balcony waist wall 40 are just sandwiched between the two fixing angles 47 of the balcony floor beam 46.

  The pressing force is applied to the outer wall panel 1A side of the balcony waist wall 40, and while the dry water blocking material 10 and the pressing plate 20 are compressed, the dry water blocking material 10 has an upward frictional force in the process of being suspended downward. You will receive

  The water blocking structure of the outer wall and the balcony waist wall according to the first embodiment, which is formed by the construction method shown in FIG. 4, will be described with reference to FIGS. 5 and 6. FIG. 5 is a view of the water blocking structure as viewed from the inside of a balcony together with a longitudinal sectional view of a wall. 6 is an enlarged view of a VI portion of FIG. 5, and in the state where the balcony waist wall 40 is seated, the bonded body of the dry water blocking material 10 and the pressing plate 20 is a recess of the outer wall panel 1A (here, a horizontal recess It shows a state in which two patterns are in contact with 1a).

  As shown in FIG. 5, in a state in which the balcony waist wall 40 is seated on the balcony floor beam 46, the bolt 48 is inserted through the bolt hole 45a of the corresponding metal plate 45 and the bolt hole 47a of the fixing angle 47. By being tightened, the balcony waist wall 40 is fixed to the balcony floor beam 46. In the state where the illustrated balcony waist wall 40 is fixed, the bonded body of the dry water stop material 10 and the pressing plate 20 enters in a state of being pressed to the horizontal recess 1 a of the outer wall panel 1A in the vicinity of the mounting portion 50 and stops A water structure 100 is formed. Here, "in the vicinity" is a meaning that indicates a position close to the attachment portion 50, and means a lower position of the end surface 41a as illustrated.

  The structure of the wall 1 is also outlined with reference to FIG. The wall 1 is an outer wall heat insulating material 1D to which an outer wall panel 1A having a handle pattern made of a siding material and the like and a moisture permeable waterproof sheet 1C disposed on the indoor side across the ventilation layer 1B are stuck in order from the outside. , Heat insulator 1E, moisture proof sheet 1F, and interior material 1G. The heat insulating material 1E is made of glass wool, rock wool or the like, and the interior material 1 is made of gypsum board or the like.

  In the water blocking structure 100, two patterns shown in FIGS. 6A and 6B, for example, in the positional relationship between the dry water blocking material 10 and the bonded body of the pressing plate 20 and the horizontal recess 1a of the outer wall panel 1A. Water blocking structure can be formed. First, the water blocking structure 100 shown in FIG. 6A has a form in which the pressing plate 20 is not in the horizontal recess 1a. While the adhesive body as a whole shows a tendency to warp upward in the X direction in a state of being pressed as a whole by the construction method shown in FIG. 4, the pressing plate 20 which is not in the horizontal recess 1a is pushed into the surface of the outer wall panel 1A. In the state as it is, the dry water blocking material 10 located below is pushed down by the pressing force P1 to suppress excessive warpage of the dry water blocking material 10, for example, the upper plate 12 and the thin rod 14 upward. By suppressing the warping of the upper plate 12 and the thin rod 14, they can sufficiently enter the bottom of the handle of the horizontal recess 1a, and even in the housing H in which the horizontal recess 1a is formed deep, The rod 14 can reach the bottom of the handle of the horizontal recess 1a. Further, the front end of the pressing plate 20 itself is in contact with the outer wall panel 1A with a certain pressing force. Therefore, together they form a high water blocking structure 100.

  Moreover, the water stop structure 100 shown in FIG.6 (b) is a form in which the holding | suppressing plate 20 has entrapped in the horizontal recessed part 1a. In this embodiment, the compressive deformation of the pressing plate 20 is alleviated, and the upper plate 12 and the thin rod 14 are pushed downward by the pressing force P2 in the horizontal recess 1a. Also in this embodiment, the warping of the upper plate 12 and the thin rod 14 is suppressed by the pressing plate 20, so that they can sufficiently enter the handle bottom of the horizontal recess 1a, and the water blocking structure is high. One hundred is formed.

  Thus, regarding the water blocking structure 100 formed at the seating position of the balcony waist wall 40, the positional relationship between the bonded body of the dry water blocking material 10 and the pressing plate 20 and the horizontal recess 1a of the outer wall panel 1A is assumed. In any case, a water blocking structure 100 having high water blocking properties is formed.

  Further, in the water blocking structure 100 according to the first embodiment, the bonded body of the dry water blocking material 10 and the pressing plate 20 is located in the vicinity of the attachment portion 50. Therefore, the tightening force of the bolt and nut at the mounting portion 50 is likely to act on the adhesive body, and the desired compression state required for the adhesive body (for example, as described above, the 30 mm overhang length is compressed to a predetermined value 12 mm) In the state, the compression ratio can be easily formed 40%.

  Although not shown in the drawings, the same is true also in the case where there is an adhesive at a position where the vertical recess 1b of the outer wall panel 1A is present, or where the adhesive is at a position where the horizontal recess 1a and the vertical recess 1b intersect. There is no change in the fact that waterproofness is obtained.

  In the state where the balcony is completed by the water blocking structure 100, the rainwater etc. which pass between the balcony waist wall 40 and the outer wall panel 1A are shut off, and the rainwater etc. constitutes the mounting portion 50. 45, it can be prevented from infiltrating the internal structural member of the balcony such as the balcony floor beam 46 and the like.

Second Embodiment
Next, the water stopping structure of the outer wall and the balcony waist wall according to the second embodiment will be described with reference to FIGS. 7 to 9. Here, FIG. 7 is a perspective view showing the balcony waist wall and the balcony floor beam before the water blocking structure of the outer wall and the balcony waist wall according to the second embodiment is formed.

  Furthermore, the lower pressing plate 20 is sandwiched between the upper and lower dry water-stopping materials 10, so that the pressing plate 20 is effectively prevented from warping upward, and is firmly in contact with the surface of the outer wall panel 1A. . This further enhances the water blocking property of the water blocking structure 200.

Third Embodiment
Next, the water stopping structure of the outer wall and the balcony waist wall according to the third embodiment will be described with reference to FIGS. 10 and 11. Here, FIG. 10 is a perspective view showing the balcony waist wall and the balcony floor beam before the water blocking structure of the outer wall and the balcony waist wall according to the third embodiment is formed. FIG. 11: is the figure which looked at the water stop structure of the outer wall and balcony waist wall which concern on 3rd Embodiment from the inside of a balcony with the longitudinal cross-sectional view of a wall.

  As shown in FIG. 10, the bonded body of the dry water blocking material 10 and the pressing plate 20 is attached to the end face 40 a of the balcony waist wall 40 at the upper position, and the lower end face 40 a of the dry water blocking material 10 At the left and right positions, dry cut-off members 30 of two other configurations extending in the longitudinal direction are disposed. The dry water-stopping material 30 is formed of a long base 31 of the same material as the dry water-stopping material 10 and a bundle of many fine rods 32. By providing a large number of slits in the vertical direction and the horizontal direction so as to secure the pedestal 31 for the elongated hexahedron, it is possible to manufacture the dry water blocking material 30 of the illustrated form.

  The balcony waist wall 40 shown in FIG. 10 is seated on the balcony floor beam 46 and bolted at the attachment portion 50, whereby a water blocking structure 300 according to the third embodiment shown in FIG. 11 is formed. In the water blocking structure 300, the bonded body of the dry water blocking material 10 and the pressing plate 20 is pressed at the upper position of the balcony waist wall 40, so that the water blocking structure 300 is as high as the water blocking structures 100 and 200 of the other embodiments. Demonstrate aqueous. However, by stopping water at the upper position of the balcony waist wall 40, when water passes through the adhesive body, there is a distance to which the water flows down to reach the attachment portion 50. It is assumed that the water flows down near the center, and in such a case, the possibility that the water infiltrates the internal structural member of the balcony increases. Therefore, in the water stop structure 300, the two left and right dry water stop members 30 extending to the attachment portion 50 prevent the water from flowing down so as to approach the center of the end face 41a. In the water blocking structures 100 and 200 of the other embodiments, the bonded body of the dry water blocking material 10 and the pressing plate 20 is located in the vicinity of the mounting portion 50 below, so that water is temporarily bonded. Even if it passes, since there is almost no distance to the mounting portion 50, there is no possibility that the water will flow down so as to approach near the center of the end face 41a, and therefore it is not necessary to provide two right and left dry water blocking members 30. However, in the water blocking structures 100 and 200 as well as the water blocking structure 300, two right and left dry water blocking members 30 of short length (because the distance to the attachment portion 50 is short) are provided below the adhesive body. It is also good.
