Description

  The present invention relates to a temporary waterproof structure and a temporary waterproof construction method.

  Conventionally, in order to prevent the inside of the building from getting wet due to rain or to prevent the construction period from being extended during the period from the start of the building's enclosure to the completion of the waterproofing work on the roof, Measures are taken. For example, in a large-scale building, many methods for providing a temporary roof that covers the entire building using a scaffold have been proposed. In a small building such as a house, a method of simply placing a sheet on the roof surface has been proposed.

  With this simple method of placing a sheet on the roof surface, there are few problems with rain in the case of a sloped roof. However, in the case of a flat roof with a parapet, a puddle is formed, and it is necessary to separately consider a method for discharging water. Based on such a study, as a temporary waterproofing technique that can significantly reduce the cost and labor and can omit almost all of the removal work, for example, the one described in Patent Document 1, etc. (See Patent Document 1).

  However, in the conventional temporary waterproof technology, there are cases where it takes time and cost to install the temporary tack. Moreover, the conventional temporary waterproofing technique may be based on the premise that there is a recess for installing the temporary tack along the outer periphery, and in this case, it cannot be handled without the recess. For this reason, it may not be said that versatility is high, such as requiring repair of an outer wall panel.

  Therefore, an object of the present invention is to provide a temporary waterproof structure and a temporary waterproof method that do not require labor and cost, have high versatility, and do not require repair of an outer wall panel.

In order to solve the above problems, the present invention is a temporary waterproof structure in an external floor having a floor slab made of a panel made of a non-waterproof material and having a wall rising portion formed around it.
A temporary waterproof sheet laid in a pool shape is included from the surface of the floor slab to the upper end surface of the wall rising portion.

  Such a temporary waterproof structure can be constructed without installing a temporary fence since the temporary waterproof sheet is laid from the surface of the floor slab to the upper end surface of the wall rising portion. For this reason, the effort and cost for installing a temporary waterproof structure are not required, and repair of an outer wall panel is unnecessary. Therefore, versatility is high.

  Such a temporary waterproof structure can be attached to a hardware formed on the inner wall surface side of the wall rising portion, and applies tension to the temporary waterproof sheet against the rising surface of the hardware. The temporary waterproof sheet may include a magnet to be stuck so as not to be depressed at the outer joint.

  In addition, the temporary waterproof structure hooks a temporary drainer having an L-shaped cross section on the upper end of the hardware so that the hanging piece is on the outside of the building, and the horizontal edge of the temporary waterproof sheet is overlapped with the edge of the temporary waterproof sheet. The upper end surface of the hardware may be continuously pasted using the same magnet.

Furthermore, the present invention is a temporary waterproofing method for an external floor having a floor slab made of a panel made of a non-waterproof material and having a wall rising portion formed around it,
Including a step of laying a temporary waterproof sheet in a pool shape from the surface of the floor slab to the upper end surface of the wall rising portion.

  According to the present invention, it is possible to provide a temporary waterproof structure and a temporary waterproof method that do not require labor and cost, are highly versatile, and do not require repair of the outer wall panel.

It is sectional drawing which shows an example of the external floor by which the temporary waterproof structure was laid. It is an enlarged view near the upper end surface of the parapet in FIG. It is a figure which shows an example of an adhesion member. It is a perspective view which shows an example of a temporary draining.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings (see FIGS. 1 to 4).

  The target external floor 100 in the present embodiment refers to an outdoor floor portion formed on, for example, a flat roof or rooftop of a building. The external floor 100 has a floor slab 110 made of a panel 120 made of a non-waterproof material. A preferred example of a non-waterproof material suitable for the outer floor 100 is ALC (Autoclaved Light weight Concrete).

  A wall rising portion such as a parapet 200 is provided around the outer floor 100 so as to surround the outer floor 100 (see FIG. 1). The parapet 200 is formed with an inner wall surface 202 which is a surface facing the center side (the side where the outer floor 100 is located) of the building or the like, and an outer wall surface 204 which is a surface facing the outside. The material of the parapet 200 of the present embodiment is ALC, but is not particularly limited to this. Further, the parapet 200 of the present embodiment does not include a headboard on the upper end surface 206, but a headboard having a width wider than the thickness of the parapet 200 (the distance between the inner wall surface 202 and the outer wall surface 204) is formed. In some cases.

  In addition, the outermost panel (the panel adjacent to the parapet 200) among the panels 120 constituting the floor slab 110 is supported by the outer roof beam 300 made of H-shaped steel. Between the outermost panel 120 of these floor slabs 110 and the parapet 200, a space that is filled with joint mortar in the subsequent process and becomes the outer joint part 150 is formed (see FIG. 1).

  On the inner wall surface 202 side of the parapet 200, a hardware 400 serving as a base when the waterproof sheet is attached is attached (see FIG. 1). The hardware 400 has a crank shape including an upper horizontal portion 400a, a vertical portion 400b, and a lower horizontal portion 400c. The upper horizontal portion 400a is on the upper end surface 206 of the parapet 200, and the vertical portion 400b is on the inner wall surface 202 of the parapet 200. The lower horizontal portion 400c is disposed and fixed so as to be respectively applied to the outer peripheral roof beam 300. In this fixed state, the vertical portion 400b of the hardware 400 becomes a rising surface, and the upper horizontal portion 400a of the hardware 400 becomes an upper end surface (see FIGS. 1 and 2).

  The temporary waterproof structure 1 is used for temporary waterproofing in the external floor 100 in which the parapet 200 is formed in this way, and includes the temporary waterproof sheet 2 and the sticking member 3. The temporary waterproof structure 1 may further include a temporary drainer 4 as a rainwater intrusion prevention member.

  The temporary waterproof sheet 2 is a sheet laid in a pool shape from the surface of the floor slab 110 to the upper end surface 206 of the parapet 200. The temporary waterproof sheet 2 is preferably composed of a single sheet and does not overlap, but is not limited to this as long as waterproofness is maintained.

  The sticking member 3 is a member including a magnet that can be stuck to the hardware 400. The sticking member 3 is not loosened so that the temporary waterproof sheet 2 is not depressed at the outer joint part 150 while applying tension to the temporary waterproof sheet 2 with respect to the vertical part (rising surface) 400b of the hardware. Affixed (see FIG. 1). Further, another sticking member 3 is stuck to the upper end surface 206 of the parapet 200 so as to press the end edge 2a of the temporary waterproof sheet 2 or the vicinity thereof.

  Although the specific structure of such a sticking member 3 is not limited, in this embodiment, the narrow and long plate 32 which has a softness | flexibility, and predetermined | prescribed in the length direction in one surface of the said plate 32 A magnet plate composed of magnets 34 attached at intervals is employed (see FIG. 3). In addition, you may employ | adopt the magnet plate accommodated in the accommodation bag as the sticking member 3. FIG.

  The temporary drainer 4 is used as a member for preventing rainwater from entering the upper end surface 206 of the parapet 200 (see FIGS. 1 and 2). The temporary drainer 4 of the present embodiment is formed of a member having an L-shaped cross section or an angle member, which is composed of a horizontal piece 4a and a hanging piece 4b (see FIG. 4). The temporary drainer 4 is a state where the end piece 2a of the temporary waterproof sheet 2 and the horizontal piece 4a are overlapped, and the hanging piece 4b becomes the outside of the building between the upper horizontal part 400a of the hardware 400 and the upper end of the parapet 200. It is hooked to cover the gap. Further, in this state, the temporary drainer 4 is the same as the other bonding member 3 that presses the edge 2a of the temporary waterproof sheet 2 or the vicinity thereof (the edge 2a of the temporary waterproof sheet 2 or It is arranged so as to be pressed against the upper horizontal portion (upper end surface) 400a of the metal object 400 (also used as another sticking member 3 for pressing the vicinity thereof) (see FIGS. 1 and 2).

  As described above, the temporary waterproof structure 1 according to the present embodiment is configured such that the temporary waterproof sheet 2 can be easily laid from the surface of the floor slab 110 to the upper end surface 206 of the parapet 200. It can be laid without it. For this reason, it is unrelated to the installation of a temporary fence requiring labor and cost. Moreover, the temporary waterproofing structure 1 of this embodiment can be laid regardless of the presence or absence of the outer joint part 150, and its versatility is high.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention.
