Description of the Related Art In recent years, a floor structure using a steel floor panel having a frame made of shaped steel has been adopted as a floor of a building such as a house for the purpose of reducing building costs and reducing on-site work. . FIG. 2 is a perspective view illustrating a steel floor panel, in which a steel floor panel 1 includes a frame 2 in which light channel steel is assembled in a rectangular shape, and a light channel steel in parallel with one side of the frame 2. It is composed of a skeleton composed of reinforcing bones 3 arranged thereon, and a face plate 4 of a structural plywood attached to the skeleton. FIG. 5 is a perspective view showing a conventional technique of laying a steel floor panel 1 on a wall of a house according to a framing wall construction method to form a floor framing. The joint between the steel floor panel 1 and the upper frame 5 in such a floor structure is shown in FIG.
As shown in FIG. 2A, the steel floor panel 1 is nailed from above the surface material 4 so as to penetrate the frame 2 at the end. As shown in FIG. 6B, the steel floor panels 1 are joined by applying tapping screws so as to penetrate the webs of the adjacent frame 2. Also,
Although not shown here, a floor structure using steel floor panels is also used in a wooden building or a steel-framed building according to another method such as a conventional framing method, which contributes to the achievement of the object. Has become.

(図5参照)。However, in such a floor structure, the main part of the steel floor panel, which is a component of the floor structure, is a shaped steel, and the thermal conductivity of the steel material is about 4 times that of wood.
Due to the feature of having a size of 00 times, its heat insulation performance is extremely low. In addition, since the plane dimensions of the steel floor panels constituting such a floor structure have not been standardized conventionally, an odd part is formed when the steel floor panels are laid, and a great deal of labor is required for processing this part. (See FIG. 5).

In the invention described, the floor frame is a steel floor panel having a plane dimension according to a module of a building according to a framed wall method,
A floor structure characterized by being laid between the cores of the building. As described above, by utilizing the fact that the distance between the cores of the building according to the framed wall construction method is modularized, the floor structure using the steel floor panel having a plane dimension on the module can be achieved. In addition, when the steel floor panel is laid, no irregular portions are generated, so that the work of installing the steel floor panel at the site is simplified, and furthermore, standardization by reducing the types of plane dimensions of the steel floor panel. Thereby, the production cost of the steel floor panel can be reduced, and thus the construction cost can be reduced.

Configuration 1-1) Steel floor panel As described above, in the steel floor panel 1 which is a component of the floor structure according to the present invention, the frame composed of the frame 2 and the reinforcing bone 3 is shaped steel (see FIG. 2). . The thermal conductivity of steel is about 400 times that of wood. From the above two characteristics, it can be said that the heat insulation performance of the building related to the floor group using the steel floor panel 1 without taking any special measures is extremely poor. That is, although the steel floor panel 1 has advantages such as high strength and good workability, there is a face that it cannot be said that the steel floor panel 1 is necessarily suitable as a component of a building as it is.

となることになる。Incidentally, the plane dimensions of the steel floor panel 1 used in the floor structure according to the present invention are an integral multiple of 455 mm in both the vertical and horizontal directions. This is based on the fact that 910 mm modules are frequently used in the frame wall construction method when the building to which the floor structure according to the present invention is applied is related to the frame wall construction method. That is, in the frame wall construction method, the distance between vertical frames is often 455 mm, and the wall center distance at this time is an integral multiple of 455 mm. Therefore, if a steel floor panel in which each side has a length of an integer multiple of 455 millimeters is used, an odd portion does not occur when the steel floor panel is laid to form a floor of a building. The interval between the reinforcing bones 3 of the steel floor panel having such a plane dimension is also 455 mm.

にする。FIG. 3 is a plan view of the first floor of a house according to the framing wall construction method using the floor structure according to the present invention thus configured, and FIG. 4 is a floor plan of the second floor. As is clear from the above figures, the steel floor panels were all laid between the cores of the walls, and the plane dimensions of all the steel floor panels were related to the module of the house. In some cases, no odd part is generated. In addition, a wooden side joist 6 or end joist 7 is always provided around a portion on the outer peripheral side surface of the floor set, which is in contact with the outside air. At this time, the frame of the steel floor panel in contact with the lateral joist 6 or the end joist 7 functions as an additional lateral joist or an anti-fall. In addition, the fitting of the steps such as the stairs is appropriately devised so as to ensure the heat insulation performance of the floor set.

However, in a building other than the house according to the framing wall method, similarly to the above, a wooden part is provided on the outer peripheral side surface of the floor frame in contact with the outside air. If the side joist 6 or the end joist 7 is provided around, the heat insulation performance of the building can be enhanced.

That is, after the wall is erected, a steel floor panel is laid and fixed on the upper frame of the wall, and wooden side joists and end joists are laid on the side of the steel floor panel at a predetermined position. You can repeat the cycle of building a wall. Of course, the construction of the first-floor floor set is the same as that in the above description in which the upper frame of the wall is replaced with a base.
