Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a support structure for a floor panel that allows the vertical height of the floor panel to be adjusted.

[Background technology]

2. Description of the Related Art Dry method 1 buildings are often used in which floors, walls, etc. are formed using architectural panels such as floor panels and wall panels.

Conventionally, even in such 1-dry 1-method buildings, in order to absorb dimensional errors in the formed cloth foundation, the first floor floor was constructed using bundled materials that were set up along the cloth foundation or independently. up,
It was formed by so-called built-in methods, such as laying the subflooring material through floor joists. Therefore, there are drawbacks such as poor floor construction efficiency and variations in construction.

In addition, the construction period for floor construction was long (therefore, the floor of the first floor could not be used for ridge work, which hindered the efficiency of ridge work. devised a solution to one part of the problem by supporting the floor panel flexibly, but the metal fittings were subject to dimensional errors, installation errors, or the fabric to which the metal fittings were attached. Variations in the height of the floor panels tend to occur due to changes in the height of the top of the foundation, and it is difficult to install the floor panels horizontally and flush.

[Purpose of the invention]

The present invention allows the height of the floor panel to be adjusted by providing a receiving piece for receiving the floor panel on the threaded shaft of the receiving bracket for receiving the floor panel, which allows the floor panel to be installed correctly, and also eliminates the use of bundle members, etc. The purpose is to provide a support structure for floor panels that can improve the efficiency of floor construction by eliminating the need for floor panels.

[Disclosure of the invention]

An embodiment of the present invention will be described below based on the drawings.

In the figure, the support structure of the floor panel is PI! Receipt fixed to H! 1. On the screw shaft 3 rotatably supported by 2,
A receiving piece 5 is screwed together to support the bottom surface of the end of the floor panel F that spans between the cloth foundations 8, and in this embodiment, the receiving metal fitting 2 is fixed to the upper surface of the cloth foundation B and is attached to the wall panel W. A push piece 7 for pressing the floor panel F is also attached to the receiving metal fitting 2.

The floor panel F is made by fitting the vertical frame members 21 and 21, each having a large height, into the notch provided on the facing surfaces thereof, and aligning the upper surfaces of the horizontal frame members 22-- and 21-21, each having a small height. A subfloor board 23 is attached to the upper surface of a plurality of frameworks spanning both ends. In addition, on the floor panel F, at both side edges and in the center position,
Both the floor base plate 23 and the vertical frame material 21 are cut out in the same shape, and a recess 25 is formed with the bottom surface 24 horizontal and open on each side of the floor panel F, and a through hole 26 is bored in the bottom surface 24. .

The top surface of the cloth foundation B is coated with mortar fi 29 and the top thereof is broken in, and anchor bolts 32 are installed at a predetermined distance on the top surface of the cloth foundation B.

The base metal fitting 4 is mounted on the upper surface of the cloth foundation B and is bolted using the anchor bolt 32, with a vertical piece 34 raised on the inner edge of the piece 33.
The lower end of the wall panel W is supported by fitting the upper end of the vertical piece 34 into the groove 35 on the lower surface of the wall panel W.

The receiving fitting 2 is a bent long piece, through which the anchor bolt 32 is inserted, and the anchor bolt 32 connects to the inner edge of an upper plate portion 37 provided with a through hole 36 attached to the base fitting 4. , by attaching it, a drooping portion 39 is formed that hangs down along the inner surface of the cloth curtain PJB. The hanging portion 39 also includes an inwardly protruding projecting portion 40 at its lower end.
0 is provided with a screw hole 42 that passes through the reinforcing plate 41 on the upper surface thereof. Note that the screw hole 42 is formed, for example, in a left-handed helix.

The screw shaft 3 is a bolt provided with a rotating portion 44 having a hexagonal head, and is inserted into the through hole 26 of the floor panel F.

Further, the screw shaft 3 has a body portion 4 in which a right-handed threaded portion 46 is carved.
A small diameter portion 50 having a left-handed threaded portion 49 that is screwed into the screw hole 42 is provided at the lower end of the portion 7 . The screw shaft 3 is rotatably supported by the hanging portion 39 by having its screw portion 49 screwed into the screw hole 42 . Further, the receiving piece 5 is screwed onto the threaded portion 46.

The receiving piece 5 is a plate having a screw hole 52 that is screwed into the threaded portion 46 of the screw shaft 3, and can move up and down as the screw shaft 3 rotates, and can support the lower surface of the floor panel F. Note that a reinforcing plate is integrally welded to the lower surface of the receiving piece 5.

Further, a nut 9 is screwed onto the screw shaft 3 above the body 47, and the nut 9 can press the pusher piece 7 by tightening the nut 9.

The push piece 7 is made of a spring material and the screw shaft 3 passes through it.
A base piece 55 is provided with a long hole 54 extending in a direction intersecting the cloth curtain WIB, and the base piece 55 is placed on the bottom surface 24. Furthermore, a protruding piece 57 extending above the cloth base B is formed on the outer edge of the base piece 55 via a hanging piece 59, so that the pushing piece 7 is bent into a substantially two-shape shape.

However, the receiving metal fitting 3 is attached to the base metal fitting 4 arranged along the cloth foundation B, the screw shaft 3 is inserted in advance into the through hole 26 of the floor panel F, and the receiving piece is inserted under the floor panel F and at the appropriate place of the threaded part 46. 5 is screwed, and the threaded portion 49 is screwed into the screw hole 42 while aligning the screw shaft 3 with the screw hole 42. Note that the receiving piece 5 is aligned in advance near a predetermined height, and a nut 9 and a pushing piece 7 are inserted above the floor panel F. Therefore, as the screw shaft 3 rotates, the threaded part 49 is screwed into the threaded hole 42 and descends, while the threaded part 46 whose direction of twisting force is opposite can lift the receiving piece 5. By making the pitch more uniform, the height of the floor panel F can be adjusted while adjusting the minute distance. Therefore, the floor panel F is laid horizontally and flush at a desired height. Further, even after the floor panel F is placed, its height can be adjusted.

Also, by tightening the nut 9 and pressing the push piece 7,
The base piece 55 of the pusher piece 7 contacts the bottom surface 24, and the protruding piece 57 contacts the upper plate part 37 and the base metal fitting 4.
The floor panel F is firmly fixed by spanning over the two sides of the cloth foundation B and pressing each side with spring properties.

In addition, in the structure of the present invention, as shown in FIG. 3, the screw shaft 3 is provided with a rotating portion 44A having a smaller diameter than the body portion 47, so that the screw shaft 3 can be installed later through the floor panel F. The structure of the present invention can be modified into various embodiments, such as by using a retaining ring 60 or the like to rotatably pivot the lower end of the screw shaft 3 to the hanging portion 39 without engaging the screw and preventing it from falling off. .

〔Effect of the invention〕

As described above, the floor panel support structure of the present invention supports the floor panel by a height-adjustable receiving piece that is attached to a receiving metal fitting fixed to a cloth foundation via a screw shaft. It becomes easier to level the floor panels, and the accuracy of floor panel installation can be improved. In addition, the floor panel can form the floor body without using eastern lumber, large drawers, joists, etc., which improves the efficiency of floor construction and shortens the construction period. It can also be used as a scaffold,
It can have many effects, such as improving the efficiency of building construction work.
