Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for insulating the floor of a sunroom used as a greenhouse, living room, etc.

Prior Art A sunroom has a light-transmitting plate attached to the ceiling or the like to let enough sunlight into the room, and the sunlight shines through almost the entire floor surface.

For this reason, if the flooring material that makes up the floor is made of wood, it will warp or warp over a long period of time, as it will warp or sag (in other words, deteriorate over time).
Due to the bending, gaps are created between the flooring materials, and cold air can enter the interior through these gaps at night or during the winter.

In order to prevent the aforementioned cold air from infiltrating, carpets may be placed on the floor, but even with this method, it is not possible to reliably prevent the aforementioned cold air from infiltrating, and it may also cause damage due to direct sunlight. Sputum deteriorates (drying)
This is not desirable because it causes

On the other hand, if synthetic resin flooring is used, which has thermal elasticity but does not warp or distort,
Since the flooring materials are connected alternately to provide an adjustment function, cold air flows into the interior through these connections.

In any case, there will be gaps in the floor of the sunroom, and cold air will seep into the interior through those gaps.

Purpose of the invention The purpose is to prevent cold air from flowing into the interior even if there is a gap in the floor.

Structure of the invention: A deck material placement part and a panel body placement part are vertically separated and integrally formed on the floor joists and stringers, and the deck material is placed in the deck material placement part, and the panel body placement part is integrally formed with the floor joists and stringers.
