  In the present invention, members constituting the floor and the outer wall are not particularly limited. However, in this embodiment, the floor and the outer wall are configured by using a lightweight aerated concrete (ALC) floor panel 2 and an outer wall panel 3, respectively. As the floor panel 2 and the outer wall panel 3, even a precast concrete (PC) panel can be used.

  When the outer wall panel 3 is attached to the side surface of the beam 1, the top edge surface 3 a is set so as to protrude above the upper surface of the floor panel 2. Then, from the difference in height between the height of the top edge surface 3a and the upper surface of the floor panel 2, the thickness of the heat insulating material 11 installed on the upper surface of the floor panel 2 and the floor base material 12 having a water gradient is further determined. The subtracted dimension is set as the height of the parapet. The height of the parapet is not particularly limited. However, when a wall surface having an opening such as a discharge window is provided on the upper surface of the floor panel 2, the height is set lower than the height of the lower edge of the opening. The

  Further, the outer wall panel 3 can have a length that is a height obtained by adding a height as a parapet to the height of the first floor (floor height), and a dimension as a height as a parapet. It is also possible to use a small wall panel formed of

  Also in the present embodiment, the outer wall panel 3 has a dimension obtained by adding a height as a parapet to the floor height, and the lower end portion is supported by using a support hardware (not shown) provided on the beam on the lower floor. And the upper predetermined part contacts the attachment member 5 fixed to the lower flange 1b of the beam 1, and a bolt (not shown) penetrates the outer wall panel 3 in the thickness direction and is attached to the attachment member 5. .

  The order of attachment of the outer wall panel 3 and the waterproof base member 4 to the beam 1 may be that the outer base panel 4 may be attached after the waterproof base member 4 is attached to the beam 1, and the waterproof base is attached after the outer wall panel 3 is attached to the beam 1. The member 4 may be attached.

  The waterproof base member 4 includes a fixed piece 4a fixed to the upper flange 1a of the beam 1, a standing piece 4b formed from the fixed piece 4a in the standing direction of the upper flange 1a of the beam 1, and an upper end portion of the standing piece 4b. The side view which consists of the free end pieces 4c which are formed and extend in the direction of the apex facet surface 3a of the outer wall panel 3 is formed in a Z-shape. Moreover, the opening part 4d for inserting the insertion piece of the holding member mentioned later is formed in the edge part close | similar to the waterproof base member 4 which adjoins the upper end part of the standing piece 4b.

  The dimension of the waterproof base member 4 along the longitudinal direction of the beam 1 is not particularly limited. However, it is preferable to have the same dimension as the width dimension of the outer wall panel 3. Further, although the material is not particularly limited, a cap member is attached to the free end piece 4c via a cap bracket, and therefore, the material having an appropriate rigidity, particularly a steel plate may be bent and formed. preferable.

  Moreover, each dimension of each piece 4a-4c of the waterproof base member 4 is not specifically limited. However, the extension dimension of the fixed piece 4a is formed in accordance with the width dimension of the upper flange 1a surface of the beam 1, and the standing height dimension of the standing piece 4b is the surface of the upper flange 1a of the beam 1 on the waterproof base member 4. When fixed to, a predetermined gap can be formed between the lower surface of the free end piece 4c and the top edge surface 3a of the outer wall panel 3. The extension dimension of the free end piece 4c is formed so as to be substantially equal to or slightly smaller than the thickness of the outer wall panel 3.

  The waterproof base member 4 configured as described above is disposed continuously in the length direction of the beam 1 and is fixed to the upper flange 1a. Since the plurality of waterproof base members 4 fixed to the upper flange 1a are independent from each other, variation occurs along the beam 1. For this reason, the adjacent waterproof base members 4 are connected to each other by the gripping member 7.

  As shown in FIG. 2, the gripping member 7 is a waterproof base member 4 continuously fixed to the beam 1 along the length direction of the beam 1, and is a side end portion of a pair of waterproof base members 4 adjacent to each other. Across the seam formed between them, the end portions (side end portions) in the length direction of the beams 1 are sandwiched between the adjacent ends of the pair of waterproof base members 4 on the free end 4C side, and adjacent to each other. By fixing the waterproof base members 4 to each other, it is possible to make a plurality of independent waterproof base members 4 continuous with each other and match the streets. For this reason, the gripping member 7 is made of a thin metal plate, for example, a steel plate, which can be easily bent by an operator, and is free of the waterproof base member 4 fixed to the beam 1 adjacent to each other. It is comprised so that the piece 4c and the standing piece 4b can be hold | gripped.

  As shown in FIG. 4, the gripping member 7 has a substantially rectangular shape in plan view and is formed in an L shape in side view. The beam has a length substantially equal to the extension dimension of the free end piece 4c of the waterproof base member 4 and is formed by a seam of substantially horizontal planes formed between the side ends of the free ends 4c of a pair of adjacent waterproof base members 4. A main body portion 7a covering from above 1 and a plurality of first hanging pieces (bending) formed by projecting from an end portion (outside of the building) perpendicular to the length direction of the beam 1 of the main body portion 7a And a pair of adjacent waterproof base members 4 which are formed by being bent 90 degrees at the opposite end (inside of the building) of the first hooking piece 7b in the main body 7a. A contact piece 7c that comes into contact with a seam formed between the side ends of the upright piece 4b and a first piece that is formed on both sides in the length direction of the beam 1 of the contact piece 7c and has a length that can be folded by the operator. A second hooking piece 7d. In addition, an opening 7e is formed at substantially the center of the main body 7a, and this opening 7e is equidistant in the length direction of the beam in order to support the handrail, for example, when a handrail is provided on the parapet. It is for penetrating the support | pillar member provided in.

  Next, a procedure of gripping a pair of adjacent waterproof base members 4 by the grip member 7 configured as described above will be described with reference to FIG. First, as shown in FIG. 4A, the pair of adjacent waterproof base members 4 are aligned along the beam 1, and the main body portion 7a of the gripping member 7 is set to the free end piece 4c of each of the pair of waterproof base members 4. The seam is straddled so as to cover the joint of the substantially horizontal plane formed by the above from above the beam 1.

  Next, as shown in FIGS. 2B and 2C, the contact pieces 7c are pressed against the rising surfaces formed by the respective upstanding pieces 4b to be faced. At this time, the second hooking piece 7 d faces the opening 4 d formed in the waterproof base member 4.

  Next, as shown in FIG. 4 (d), the second hooking piece 7d is bent and inserted into the opening 4d, and the inner end of the free end piece 4c is turned around to turn the back surface of the free end piece 4c. Bend approximately 90 degrees from the original state so as to be hooked to the side. Similarly, the first hooking piece 7b is bent from the original state by approximately 180 degrees, and the end of the free end piece 4c outside the building is turned and bent so as to wrap the back surface from the surface of the free end piece 4c.

  As described above, a plurality of waterproof base members 4 continuously installed on the beam 1 are integrated with each other via the gripping member 7, and the waterproof base member is easy to meander in the length direction of the beam 1. It is possible to secure the linearity on the free end piece 4c side of 4 (so that the so-called streets are aligned along the length direction of the beam 1), and the force is concentrated on any waterproof base member 4 Even in such a case, this force can be transmitted to another adjacent waterproof base member 4 to be borne.

  When the above-described support member (flat bar) fixed to the flange 1a surface of the beam 1 is fixed, the opening 7e of the gripping member 7 is first passed through the support member, and thereafter It is possible to connect the adjacent waterproof base member 4 through the gripping member 7 by working in the same procedure as.

  When the plurality of waterproof base members 4 are fixed along the beam 1 and connected via the gripping member 7 as described above, the free end piece 4c of the waterproof base member 4 and the outer wall panel 3 are connected as shown in FIG. A gap 9 having a predetermined dimension is formed between the head edge surface 3a. By forming the gap 9, it is possible to prevent damage to the outer wall panel 3 due to the screws when fixing the hardware for attaching the head member to the free end piece 4c with the screws.

  In the waterproof base structure, since the waterproof base member 4 is continuously arranged along the surface on the indoor side of the outer wall panel 3, when starting up the waterproof steel sheet or the waterproof sheet to be laid on the floor surface, It becomes possible to construct along the free end piece 4c from the standing piece 4b. For this reason, it becomes possible to construct the waterproof layer without bringing the waterproof member into direct contact with the outer wall panel 3.

  In addition, even when the head member is installed above the top edge surface 3a of the outer wall panel 3, it is possible to fix the hardware as a base to the free end piece 4c, and there is no need to fix it directly to the outer wall panel 3. Therefore, the outer wall panel 3 is not damaged.

  Next, the waterproof structure of the parapet will be described with reference to the drawings. FIG. 6 is a cross-sectional view illustrating the waterproof structure of the parapet. In the figure, the waterproof base structure uses the above-described embodiment, and the description is omitted by using the same reference numerals.
