Description

  The present invention relates to a building having a temporary waterproof structure.

  Conventionally, various measures have been taken to prevent the inside of the building from getting wet due to rain or extending the construction period during the period from the start of the building's frame to the completion of waterproofing of the roof. Has been.

  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. However, with such a simple method, although there are few problems with rain in the case of sloped roofs, a puddle is formed in the case of flat roofs with parapets, and it is necessary to separately examine the method of draining water. was there.

  Therefore, in recent years, a waterproof structure for a flat roof has been proposed that is configured so that rainwater can be discharged naturally by using a balloon so that the central portion of the seat is higher than the parapet and is provided with a gradient (for example, patents). Reference 1).

  However, adopting a waterproof structure as described in Patent Document 1 requires a device for inflating the balloon, and requires installation and removal of the device, which requires considerable costs and labor. There's a problem. Moreover, when such a waterproof structure is adopted, the central portion of the seat becomes high, so that rainwater flows down in all directions, which may hinder the work on the outer periphery of the building. Further, when such a waterproof structure is adopted, it is necessary to remove all of the waterproof construction, and if there is rain during the removal work, the inside of the building may be wetted.

  The present invention has been made in view of such circumstances, and it is possible to install a building with a temporary waterproof structure that can be installed while drastically reducing costs and labor, and that can omit almost all of the removal work. It is intended to provide.

  In order to achieve the above object, a building according to the present invention has an outer peripheral roof beam arranged on the outer periphery of the building, a roof slab installed on the outer peripheral roof beam, and an outer periphery so as to protrude above the upper surface of the roof slab. A chest wall disposed outside the roof beam, and a temporary waterproof structure installed after the roof slab is installed. The temporary waterproof structure has a U-shaped cross-section mounted on the outer roof beam so as to be positioned below the upper surface of the roof slab, and is connected to the side surface of the temporary fence and penetrates the chest wall. A temporary drainage drain provided so as to protrude outward, a first temporary tarpaulin that covers the entire top surface of the roof slab and is attached so that an edge portion hangs down inside the temporary fence, and a chest wall And a second temporary waterproof sheet that is attached so that the edge portion hangs down inside the temporary tack.

  If this configuration is adopted, the temporary fence is placed on the outer roof beam, a temporary drainage drain that penetrates the chest wall from the side of the temporary fence and communicates with the outside of the chest wall is provided, and two types of temporary waterproof sheets are attached. A temporary waterproof structure can be installed just by doing. Therefore, it is possible to significantly reduce the cost and labor required for installing the temporary waterproof structure.

  In the building according to the present invention, it is preferable to set the outer width dimension of the temporary helmet so as to correspond to the separation dimension from the inner side surface of the chest wall to the edge of the roof slab.

  When such a configuration is adopted, the temporary lock is sandwiched and restrained between the chest wall and the roof slab, so that the displacement of the temporary lock in the width direction can be suppressed.

  Moreover, the building which concerns on this invention can further be equipped with the heat insulating material affixed on a roof slab, the protection board which protects a heat insulating material, and this waterproof sheet affixed on a protection board. In such a case, the heat insulating material, the protective plate, and the main waterproof sheet can be attached with the temporary waterproof structure remaining.

  By adopting such a configuration, it is possible to complete the waterproofing work with the waterproof sheet without removing the temporary waterproof structure, so that the labor of the removal work can be saved. Moreover, even if there is rain during the construction of the waterproof sheet, the inside of the building is not wetted.
