DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a floor panel used in forming the floor of a building.

[Prior Art] Conventionally, as a floor panel used to form the floor of the first floor of a building, a framework is formed using frame materials, a plurality of wooden joists are fixed between the opposing frame materials of this framework, and the wooden joists are There was one with surface material fixed to the top surface.

However, in this structure, if long members were used for the wooden joists in order to increase the size of the floor panel, the wooden joists lacked strength, making it impossible to increase the size of the floor panel.

Therefore, in order to increase the size of the floor panel, it was proposed that the floor panel be supported by floor beams. In this structure, a connecting plate is provided on the lower surface of the floor panel, and a working opening is formed in the surface material above the connecting plate, so that the floor panel can be connected to the floor beam from above. Additionally, in order to improve the insulation properties of the floor panels, a heat insulating material was provided inside the floor panels.

[Problem to be solved by the invention]

However, with this structure, although it is possible to increase the size by supporting the floor panels with floor beams, the insulation material gets in the way when connecting the floor panels and floor beams, making the work difficult. . Therefore, an attempt was made to improve workability by removing the heat insulating material at the work opening position, but this structure had a problem in that the heat insulating properties of the floor panel deteriorated.

Therefore, an object of the present invention is to provide a floor panel that can be made large and maintain its heat insulation properties.

[Means to solve the problem]

In the floor panel of the present invention, a plurality of wooden joists are fixed within a framework formed of frame materials, a surface material is fixed to the upper surface of the wooden joists and the frame material, and a back surface of the surface material is fixed between the wooden joists. In the floor panel formed by fixing a heat insulating material in contact with the frame material, a steel connecting plate is fixed to the lower surface of the frame material and the wooden joists in a state perpendicular to the longitudinal direction of the wooden joists, and A working opening is formed in the surface material above the connecting plate, the heat insulating material is provided in a separated state at the position of the working opening, and at least the heat insulating material near the working opening is an elastic heat insulating material. This is a characteristic feature.

(Function) According to the structure of the present invention, since the steel connecting plate is fixed to the frame material of the floor panel and the lower surface of the wooden joist, the wooden joist can be reinforced and the strength of the floor panel can be increased. Therefore, it is possible to increase the size of the floor panel.Moreover, by forming a working opening in the surface material above the connecting plate,
Since the insulation material is separated at this working opening position, it is possible to reach inside the floor panel from between the insulation materials, and it is possible to work on connecting the connecting plate and the floor beams that support the floor panel. It can be carried out. Furthermore, since an elastic heat insulating material is used as the heat insulating material near the work opening, even if the hand is removed after the work is completed, the elastic heat insulating material returns to its original position and no gap is created. Therefore, the heat insulation properties of the floor panel can be maintained.

Therefore, it is possible to increase the size of the floor panel. Moreover, a working opening is formed in the surface material above the connecting plate, and the insulation material is separated at the position of this working opening, so it is possible to reach inside the floor panel from between the insulation materials. It is possible to perform connection work between the connecting plate and the floor beams that support the floor panel. Furthermore, since an elastic heat insulating material is used as the heat insulating material near the work opening, even if the hand is removed after the work is completed, the elastic heat insulating material returns to its original position and no gap is created. Therefore, the heat insulation properties of the floor panel can be maintained.
