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).

Accordingly, the present invention has been made in view of the above problems, and improves the floor structure of a building constructed by laying steel floor panels to enhance heat insulation performance. The objective is to improve the heat insulation performance of the building related to the floor structure and reduce the building cost by standardizing the dimensions.

The same reference numerals are used for the same elements, and duplicate description will be omitted.

[0008] 1. 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.

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.

FIG. 3 is a plan view of a first floor of a house according to the frame wall method. Further, FIG. 4 is a floor plan of the second floor when the floor structure according to the present invention is used in the house shown in FIG. As shown in the figure, by using several types of steel floor panels 1 having an integral multiple of 455 mm in both the vertical and horizontal directions, the steel floor panels 1 are placed between the center of the wall of the house, and the odd part is formed. It can be laid without gaps without generating.

1-2) Floor structure FIG. 1A is a perspective view showing an embodiment of a floor structure according to the present invention. As shown in the figure, the present invention is characterized by wooden lateral joists 6 and end joists 7 provided around the outer peripheral side surface of the steel floor panel 1 laid on the upper wall frame 5. These wooden side joists 6 and end joists 7 are so-called heat bridges that are hardly transmitted to the inside of the floor assembly by being provided around the outer peripheral side surface of the floor assembly that is in contact with the outside air. Play a role in preventing. In addition,
By using wood with high dimensional stability, such as glued laminated timber and LVL, as the lateral joist 6 and the end joist 7, it also plays a role of restraining and fixing the entire floor set composed of laid steel floor panels from the outer periphery. Become.

FIG. 1B is a longitudinal sectional view showing a main part of an embodiment of a floor structure according to the present invention. As shown in the figure,
The joining of the steel floor panel 1 to the wall upper frame 5 in the floor structure according to the present invention is performed by nailing from above the face material 4 so as to penetrate the frame 2 at the end of the steel floor panel 1 as in the related art. Performed by The end joist 7 is fixed to the web of the frame 2 of the steel floor panel 1 with a screw screw. In the figure, the joining of the steel floor panel 1 to the upper wall frame 5 and the joining of the end joist 7 to the steel floor panel 1 are illustrated, but the joining of the steel floor panel 1 to the base and the side joist 6 The same applies to the connection with the steel floor panel 1.

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.

In the above-described embodiment, a house according to the framing wall method has been exemplified. 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.

2. Construction procedure Construction of buildings related to the framed wall method is performed in the same procedure as usual. 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.

[0016]

As described above, in the floor structure using the steel floor panel according to the present invention, the floor which comes into contact with the outside air while taking advantage of the strength of the steel floor panel of high strength and good workability. By constructing wooden side joists and end joists, whose thermal conductivity is significantly lower than that of steel, on the outer peripheral side of the set, it is possible to compensate for the disadvantages of steel floor panels that insulation performance is low, and The heat of the outside air is hardly transmitted to the inside of the set, and a floor structure having high heat insulation performance can be configured, and the heat insulation performance of a building related to the floor structure can be improved. In addition, by using wood having high dimensional stability as the wooden member, it also plays a role of restraining and fixing the entire floor set composed of the laid steel floor panels from the outer periphery.

Further, utilizing the fact that the distance between the cores of the building according to the framed wall construction method is modularized, a floor structure using steel floor panels having a plane dimension on the module is used. Accordingly, when the steel floor panel is laid, an odd portion is not generated, so that the work of installing the steel floor panel at the site is simplified, and further, the types of the plane dimensions of the steel floor panel are reduced and standardized. Thereby, the production cost of the steel floor panel can be reduced, and thus the construction cost can be reduced.
