DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for a floor formed between entrances and exits of a building, and a method for constructing the waterproof structure.

[0002]

2. Description of the Related Art At entrances and exits such as a porch where a space is formed below and an entrance on the second floor,
Since the lower frame of the opening frame for storing the door needs to be fixed to the beam, waterproofing of the floor is conventionally performed by dividing the lower frame into the outdoor side and the indoor side as shown in FIG. In addition, the waterproof property of the lower frame part is likely to be impaired because it is discontinuous, and the waterproofing layer that is performed as waterproofing on the outdoor side ends at the rising part of the lower frame, and the indoor side separately as a part of unspecialized carpentry Due to the waterproofing work, there still remains a problem in the reliability of waterproofing inside the entrance.

In addition, since the waterproof layer from the outdoor side is completed by the lower frame, it is necessary to provide the lower frame to some extent higher than the level of the waterproof layer in order to prevent rainwater from entering. When the room enters and exits, the vehicle is straddled over the lower frame, and this step particularly hinders the passage of the elderly and the disabled.

The present invention has been made in view of the actual situation of a conventional waterproof structure, and aims at proposing a waterproof structure which ensures waterproofness of a lower frame portion and eliminates a step between a lower frame and a floor surface. is there.

[0005]

According to the present invention, a waterproof layer is provided on the lower surface of the lower frame from the outdoor side to the indoor side to ensure waterproofness between the lower frame and the indoor side, and at the same time, the upper end of the lower frame is connected to the floor. Eliminate steps between surfaces. As the waterproof layer is continuous across the lower frame, the lower frame and the skeleton are insulated,
A connection between the lower frame and the skeleton is ensured by installing a mounting member for fixing the lower frame to the skeleton at the position of the lower frame on the waterproof layer.

[0006] The waterproof layer is continuously laid inside and outside the room on the lower surface side of the lower frame of the opening frame for housing the door, and is an attachment member for fixing the lower frame to the frame at the position of the lower frame on the waterproof layer. Is installed.

[0007] The mounting member is installed on the skeleton by penetrating the waterproof layer, and the portion penetrating the waterproof layer is preliminarily subjected to a caulking treatment so as to avoid a decrease in the water tightness of the waterproof layer caused by penetrating the waterproof layer. And maintain the continuity of the waterproof layer through the interior and exterior of the room.

When the waterproof layer is continuous between the outside and the inside of the room with the lower frame interposed therebetween, the waterproof property of the lower frame portion is secured, and the waterproofness of the inside of the entrance is secured by not dividing the construction area. In addition, when the waterproof layer is continuous, it is not necessary to secure a distance between the lower frame and the floor surface when the partition is sandwiched by the lower frame, that is, it is not necessary to secure a distance from the waterproof layer to the upper end of the lower frame. .

[0009] The waterproof floor is installed on the lower surface side of the lower frame of the opening frame.
This is performed in such a manner that a waterproof layer is previously penetrated and integrated therewith, and a mounting member in which a penetrating portion of the waterproof layer is subjected to a caulking process is installed and this is fixed to a skeleton.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing one embodiment.

According to the first aspect of the present invention, as shown in FIG. 1, a lower frame 1 of an opening frame for storing a door installed at an entrance of a building.
A waterproof layer 2 continuous inside and outside the room is laid on the lower surface side of the
An attachment member 3 for fixing the lower frame 1 to the frame 7 is provided at the position of the lower frame 1 on the waterproof layer 2.

As shown in FIG. 2, the waterproof layer 2 is continuously laid from the outside of the room to the inside of the entrance on the inside of the room with the lower frame 1 interposed therebetween.
The indoor end is raised up to the floor. Since the mounting member 3 is installed at the position of the lower frame 1, the waterproof layer 2 is located outside the room.
Side waterproof layer 21 and indoor waterproof layer 22
The waterproof layer 21 is integrated with the mounting member 3 in advance so that the indoor waterproof
Layer 22 is superimposed on site. The waterproof layer 21 on the outdoor side has a depth to the middle of the indoor side beyond the lower frame 1 and is superimposed on the waterproof layer 22 on the indoor side, and both waterproof layers 21 and 22 are laid between them from above. The connection is continued by the connecting member 4. For example, a vinyl chloride sheet is used for the waterproof layer 21 on the outdoor side and the waterproof layer 22 on the indoor side, and a steel plate coated with vinyl chloride is used for the connecting member 4.
Welded to.

The mounting member 3 has a support piece 31 on which the lower frame 1 is mounted, and a mounting piece 32 to which the lower frame 1 is fixed, and penetrates the waterproof layer 21 through the back plate 5 arranged on the lower surface side of the waterproof layer 21. Are connected by bolts 6. A joining member 8 for joining to a building body 7 of the building is installed under the back plate 5 and is connected to the building body 7 by bolts 10 in advance. The bolt 10 penetrating the joining member 8 is welded to the joining member 8 in advance, and is fixed to the frame 7 by tightening a nut.

The lower frame 1 has bolts 10 attached to the mounting pieces 32 of the mounting member 3.
Is fixed by

The mounting member 3 and the back plate 5 are assembled as a single component in advance with bolts 6 with the waterproof layer 21 interposed therebetween, and installed on the joining member 8 in an integrated state. Mounting member 3
A packing 9 is interposed between the watertight layer 21 and the watertight layer 21 to prevent watertightness weakness due to a hole of the bolt 6 penetrating the waterproof layer 21, and caulking around the bolt 6 for closing the bolt hole of the support piece 31. Processing is performed in advance at the factory.

A third aspect of the present invention is a method for constructing the first aspect of the present invention, wherein a waterproof layer is provided on the lower surface of the lower frame 1 in advance.
The mounting member 3 which penetrates through and integrates with the mounting member 3 and is subjected to caulking treatment at the portion penetrating the waterproof layer 21 is fixed to the frame 7 to complete the process.

[0017]

The present invention is as described above. Since the waterproof layer is continuous on the lower surface side of the lower frame, the waterproof property of the lower frame is ensured. Can also be secured. In addition, since the waterproof layer is continuous, there is no need to start up at the lower frame portion, so that it is not necessary to secure a distance from the waterproof layer to the upper end of the lower frame, and it is possible to eliminate a step between the upper end of the lower frame and the floor surface. .

As the waterproof layer is made continuous on the lower surface side of the lower frame, a mounting member for fixing the lower frame to the frame is installed at the position of the lower frame on the waterproof layer. By fixing the waterproof layer to the skeleton by penetrating it while maintaining the waterproof performance of the above, it is possible to avoid a decrease in the water tightness of the waterproof layer due to the waterproof layer being sandwiched between the mounting member and the skeleton.
