Abstract

PROBLEM TO BE SOLVED: To provide a floor structure capable of being fixed onto a continuous footing by correcting the strain of a floor panel more effectively, having excellent workability and being used for the lower section of a sweeping-out opening section and a method for executing a floor. SOLUTION: A joining member 5 is fixed onto the floor panel 3 so that a pushing section 54 is abutted against the joining section 82 of the floor panel 3 from an upper section. The floor panel 3 is placed on the continuous footing 1 by inserting a fastening section 52 to an anchor bolt 2, and the joining member 5 is fastened to the anchor bolt 2. Accordingly, fastening axial force pushes the joining section 82 of the floor panel 3 through the pushing section 54 and works so as to correct the strain of the floor panel 3 while fixing the floor panel onto the continuous footing 1. A half-sill 4 is placed on an approximately outer half on the continuous footing 1, and fixed onto the floor panel 3 by an adhesive, nails or the like.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure and a floor construction method used in a panel construction method for constructing a house or the like.

[0002]

2. Description of the Related Art Conventionally, as one of industrialized houses, a panel construction method in which structural materials such as floors, walls, and roofs are previously panelized in a factory or the like, and these panels are assembled at a construction site to construct a house. Has been adopted. The panel is
For example, it is common to assemble a crosspiece into a rectangular frame shape, assemble reinforcing crosspieces vertically and horizontally as needed in the frame body, and attach a face material such as plywood on the upper surface of the frame body. Panels for floors, walls, roofs, etc. are assembled at the factory,
Trucks are carried to the construction site. At the construction site,
The basic structure of a house, such as floors, walls, and roofs, can be constructed in a short period of time only by installing panels and joining panels.

One type of floor structure in the panel method is a floor structure using a semi-base. The semi-base is a base formed by a timber or the like which is installed at about the outer half of the thickness on the cloth foundation. A plurality of floor panels are laid on the inner half of the thickness of the cloth foundation, and a semi-base is placed on the outer half to form a floor. Then, a plurality of wall panels are erected on the floor, and the wall is formed by fastening with nuts or the like to portions of the anchor bolts protruding above the upper surface of the floor panel.
By fastening the wall panel to the anchor bolt,
The floor panel and the semi-base are fixed to the cloth foundation by receiving the fastening axial force. On the other hand, in a sweeping opening for installing a long span fitting such as a sweeping window sash, the fitting must be mounted so as to be flush with the upper surface of the floor panel. Therefore, it is not possible to fix the wall panel and the floor panel and the semi-base to the fabric foundation by projecting the anchor bolts further upward from the upper surface of the floor panel as described above.

[0004] Therefore, conventionally, in the sweeping opening, the floor panel is fixed on the cloth base by using a special joining metal fitting, and then the half base is placed on the outer half of the thickness of the cloth base and the side panel is placed from the side. A method of fixing to a floor panel with an adhesive, a nail, or the like is adopted. In this way, the floor panel and the semi-base can be fixed to the cloth foundation even at the sweeping opening. Specifically, for example, JP-A-10-88722 can be mentioned.

[0005]

However, in Japanese Unexamined Patent Application Publication No. 10-88722, in the fixing device for a floor panel in the form of a feather board shown as the first embodiment, the fixing device firstly extends the anchor from the cloth base. In order to fix the floor panel to the bolt and then to attach the floor panel to the end face of the floor panel from a substantially horizontal direction, the force for pressing the floor panel vertically downward is insufficient. For this reason, the floor panel may be fixed with distortion remaining, which makes it difficult to align the wall panel when standing or installing a fitting, and in some cases, there is a problem that a repair work must be performed. In the U-shaped fixing bracket shown as the second embodiment of the publication, in order to cope with the above problem, a bar is applied to the end of the fixing bracket, and the floor panel is pressed by the lever principle. Although the fixing method is used, there is still a problem that the operation is complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a floor structure used under a sweeping opening and a method for constructing a floor, in which a floor panel can be fixed to a cloth foundation more effectively, and which has good workability. is there.

[0007]

Means for Solving the Problems To solve the above problems, the invention according to claim 1 is, for example, as shown in FIGS. 1 to 4 (or FIGS. 5 to 7), a cloth base 1 (11). The base (semi-base 4 (14)) is placed on the outer half of the thickness on the upper side, the end of the floor panel 3 (13) is placed on the inner half, and the fabric base 1 (11) is placed on the upper side. A floor structure in which the base 4 (14) and the end of the floor panel 3 (13) are fastened to anchor bolts 2 (12) extending toward the anchor bolts 2 (12) via joining members 5 (15). Notches 8, 9 (18) which are opened at the end face and the upper and lower faces at positions opposed to each other at portions where the base 4 (14) and the floor panel 3 (13) are fastened to the anchor bolts 2 (12). , 19) are provided, and the notch 8 (18) in the floor panel 3 (13) is provided. Includes a joint 82 (182) which focus member having an upper surface contacting, the joining member 5 (15)
