DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escape hatch mounting structure for an outdoor floor such as a balcony of a house.

[0002]

2. Description of the Related Art Evacuation hatches have conventionally been provided on outdoor floors of balconies on upper floors. The evacuation hatch is installed by welding and fixing a reinforcing bar from a wet concrete floor.

[0003]

However, in the conventional mounting structure of the evacuation hatch, there is a problem that a step is generated between the evacuation hatch and the surrounding floor surface, or the appearance is deteriorated due to a different color. Was. Also, since the construction method is a wet method, it takes time to weld the evacuation hatch to the reinforcing steel, or it is necessary to arrange concrete plates in small pieces around the evacuation hatch, which hinders performance and construction. There was a problem that would occur.

[0004] It is an object of the present invention to provide an outdoor floor evacuation hatch mounting structure which can easily finish the surface and is excellent in workability.

[0005]

According to a first aspect of the present invention, there is provided an evacuation hatch mounting structure for an outdoor floor in which the size of the evacuation hatch mounting opening is adjusted according to the size of the evacuation hatch mounting opening on the outdoor floor on which the floor panel is laid. The evacuation hatch main body with an apron protruding around the entire upper part is attached, and the surface of the floor panel adjacent to the surface of the apron is made substantially flush and substantially the same color.

According to the evacuation hatch mounting structure for an outdoor floor according to the first aspect, the evacuation hatch can be mounted by a dry method since the main body of the evacuation hatch is inserted and mounted in the evacuation hatch mounting opening formed in the outdoor floor. The workability is improved.
In addition, the apron protruding from the entire circumference of the upper part of the evacuation hatch is almost flush with the surface of the floor panel around the evacuation hatch, making it easy to finish it according to the floor just by attaching the evacuation hatch. Can be done.

According to a second aspect of the present invention, there is provided an evacuation hatch mounting structure for an outdoor floor according to the first aspect, wherein a bent piece is formed on an outer edge of the apron so as to hang down substantially by the same thickness as an adjacent floor panel. And a joint material is loaded between the adjacent floor panel and the wall component. According to the evacuation hatch mounting structure for an outdoor floor according to the second aspect, in addition to the operation of the first aspect, the joint material can ensure watertightness between the evacuation hatch and an adjacent floor panel or a wall component. it can. Further, since the length of the bent piece is substantially the same as the thickness of the floor panel, the joint between the floor panel and the floor panel can have the same configuration as the joint between the floor panels, thereby improving the workability. .

According to a third aspect of the present invention, there is provided an evacuation hatch mounting structure for an outdoor floor according to the first or second aspect, wherein a mounting piece is protruded from the entire periphery of the main body of the evacuation hatch below the apron projecting position. The mounting piece is engaged with a floor assembly provided below the surface of the opening, and the four corners of the mounting piece are fixed to the floor assembly with fasteners. According to the evacuation hatch mounting structure for an outdoor floor according to the third aspect, in addition to the operation of the first or second aspect, the mounting of the evacuation hatch is performed in a state where the mounting pieces are locked and temporarily supported by the floor assembly. And the construction is very easy. Further, since the upper part of the fixing tool for fixing the mounting piece is covered with the apron, the surface finishing is not required.
