Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a technique for attaching floor panels without using bundles when constructing the floor of a house.

[Background technology]

Conventionally, in the case of floors in houses, bundles were erected on a bundle foundation, the bundles supported the floor panels, and the floor panels were supported by the floors. For this reason, in the past, bundles were required to support the floor panels, and when the bundles were erected, there was a problem that the bundles would be lifted up by frost heave in winter in cold regions and the floor panels would be lifted up.
Therefore, when installing floor panels without using bundles, as shown in Fig. 3, the upper horizontal piece 3 of the floor panel support bracket 2, which is shaped like an inverted L, is placed on the top surface of the foundation 1. At the same time as installing the floor panel 5, place the end of the floor panel 5 on the floor panel mounting portion 9 that protrudes outward from the vertical piece 4 of the floor panel receiving bracket 2 along the side surface of the foundation 1, and attach the floor panel fixing bracket 6 to the floor panel. It is conceivable that the floor panel 5 be attached by tightening the bolts 7 to the receiving fittings 2 and pressing the upper surface of the end portion of the floor panel 5 with the pressing pieces 8 of the floor panel fixing fittings 6. However, in the case shown in Figure 3,
When the floor panel 5 is attached by tightening the bolts 7, it is not securely fixed properly, and due to the thinness of the wood of the floor panel 5, there is a gap between the floor panel 5 and the hardware, which causes the floor to rumble.

[Purpose of invention]

The present invention was devised in view of the above points, and its purpose is to enable floor panels to be easily and securely installed even if the bundles supporting the floor panels are removed, and to enable frost heaving. To provide a mounting structure for a floor panel that does not have any effect on the floor panel even if the floor panel is damaged, and also prevents floor noise by not creating gaps between the floor panel and hardware due to thinning of the wood of the floor panel, etc. It is in.

[Disclosure of invention]

[Effect of idea]

As described above, this invention allows the floor panel to be clamped and installed by placing the floor panel on the floor panel receiving bracket attached to the foundation and fixing it with the floor panel fixing bracket. Since the floor panel can be supported and installed using the panel support metal fittings and the floor panel fixing metal fittings, it is no longer necessary to use a bundle when installing the floor panel, as was the case in the past. Since this is not necessary, there is no effect on the floor panel even if there is frost heaving, and since it can be installed simply by clamping with metal fittings, it is possible to save labor during construction. In addition, a pair of slits were provided in parallel in a part of the fixing piece of the floor panel fixing bracket, and a bolt insertion hole was provided between the pair of slits, and the bolt was inserted through the bolt insertion hole and installed in the floor panel receiving bracket. It is screwed into the nut part, and the pressing piece is pressed against the upper surface of the end of the floor panel, and the backing piece is pressed against the upper surface of the foundation either directly or through other inclusions, so when the bolt is tightened, the pressing piece is strongly pressed against the upper surface of the end of the floor panel using the fixing piece as a fulcrum, and the part between the slits of the fixing piece is elastically deformed so as to bend downward, and the pressing piece is pushed downward by the reaction force of this elastically deformed part trying to recover. This allows the floor panel to be firmly attached by strongly pressing the upper surface of the end of the floor panel, and also has a pressing piece that works to restore the area between the slits even if the wood thins. It can be pressed against the upper surface of the edge of a floor panel to prevent floor noise, and the part between the slits can be elastically deformed to act as a spring washer and reliably prevent bolts from loosening. be.
