DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, although the present invention is explained based on an embodiment, referring to an accompanying drawing, the present invention is not limited only to this embodiment.
[0040]
FIG. 1 is a perspective view showing a floor structure according to an embodiment of the present invention, more specifically, a floor structure formed by a filling thermal insulation method.
[0041]
As shown in FIG. 1, the floor structure K is a two-legged floor support composed of a floor base plate 1, a steel pulling 2 that supports the front and rear ends of the floor base plate 1, and a steel bundle 3. The tool S and the heat insulating member 4 that insulates the floor are provided as main components. In this case, as shown in FIG. 1, the floor base is provided with a plurality of rows of floor base plate materials 1 arranged in a column.
[0042]
The floor base plate 1 is, for example, a structural plywood such as a softwood plywood having a predetermined thickness (for example, 28 mm thickness), that is, a so-called thick structure plywood. A corner 1 is provided with a tongue 1a on one side of the floor substrate 1 and a groove (so-called small hole) 1b on the other side to form a tongue-and-groove structure (see FIG. 2). As shown in FIG. 1, it is appropriately cut out in accordance with the corner of the column C. The side portion of the floor base plate 1 has a tongue-and-groove structure, and by bonding the tongue and groove with an adhesive, the side portion does not have to be supported by the steel draw 2 over the entire length. Floor magnification is secured.
[0043]
Moreover, the side edge by the side of the fabric foundation B of the floor foundation board | plate material 1 is mounted in the base 5 arrange | positioned on the fabric foundation B, as shown in FIG.
[0044]
The two-legged floor support S is composed mainly of a steel pulling 2 and a pair of steel bundles 3 and 3 disposed at both ends of the bottom of the steel pulling 2. Here, as shown in FIG. 1, the steel bundles 3 and 3 are arranged in the center and are made to coincide with the width of the floor base plate 1 on which the shaft center is placed. Since the two-legged floor support S is configured as described above, the main part (the part supported by the steel bundles 3 and 3 of the steel pulling 2) of the floor base plate material 1 of the row. While supporting the front end portion or the rear end portion, the side end portion of the floor base plate 1 in the adjacent row at the end portion (the portion outside the portion supported by the steel bundles 3, 3 of the steel pulling 2) It is supposed to support the center.
[0045]
That is, the floor base plate 1 is basically supported by the steel bundle 3 of the double-legged floor support S in the row at the front and rear squares, and the double-legged floor support in the adjacent row at the center of the side. It is supported by a steel bundle 3 of S.
[0046]
As shown in FIG. 3, the steel-drawn steel 2 is formed by caulking the first material 21 constituting the bottom surface 2a and the second material 22 constituting both sides 2b, 2b and the upper surface 2c at both sides of the bottom surface 2a. It is supposed to be. Since the caulked portion is composed of four layers, the bending is reinforced by itself. That is, the steel draw 2 is a self-reinforced steel draw.
[0047]
Since the steel drawing 2 is composed of two materials as described above, the thickness of the bottom surface 2a requiring strength can be increased, and the thickness of the other surfaces 2b and 2c can be decreased. Therefore, the desired strength can be achieved while reducing the size and weight. For example, by setting the size of the steel pull 2 to 60 mm × 60 mm square, the thickness of the bottom surface 2 a to 1.0 mm, and the thickness of both side surfaces 2 b and 2 b and the top surface 2 c to 0.8 mm, the conventional 90 mm × 90 mm square size The weight reduction of about 2kg per meter is achieved in comparison with the wooden large drawing. Further, since the size of the steel drawer 2 can be reduced, the surface area, that is, the heat transfer area can be reduced, and so-called thermal bridge problem can be easily taken. In addition, for example, a galvanized steel sheet is used for the steel pulling 2.
[0048]
Furthermore, as shown in FIG. 3, the bottom surface 2a, both side surfaces 2b and 2b, and the upper surface 2c of the steel pulling 2 are appropriately formed with unevenness to enhance the rigidity of the surface itself and to reinforce it. Thereby, size reduction of the steel drawing 2 is promoted.
[0049]
As shown in FIG. 4, the steel bundle 3 is attached to the turn bush 32 and a bundle body 31 formed of a cylindrical body having a turn bush 32 disposed at an upper end portion and a base plate 33 disposed at a lower end portion.

In the state where the bolt head storage portion 25a is protruded in a state where it is in contact with the drill head, the drill screw is inserted from the drill screw insertion through hole 25c. Time This is done by inserting the SB, passing the tip of the drill screw SB through the steel pull 2 and screwing the drill screw SB to the bottom surface 2a of the steel pull 2. By attaching the bundle attachment member 25 in such a manner, the so-called thermal bridge problem between the steel draw 2 and the steel bundle 3 is prevented, and the draw insulation member 4B is provided with the insulation member receiving portion 25d. A notched side edge 42 can be received.
[0057]
Further, for example, the steel bundle 3 is attached to the steel puller 2 to which the bundle attachment member 25 is attached. For example, a T bolt (level adjustment bolt) 34 shown in FIG. Lock nut) 37 is screwed, and then the T bolt head 34a is inserted into the bolt head storage portion 25a from the bolt head insertion through hole 25b provided in the bundle mounting member 25, and the stopper 25e. Rotate until it touches. In this state, the upper lock nut 37 is screwed and tightened toward the bolt head 34a. (Thus, the bolt head 34a is held by the bundle receiving heat insulating member 24 and the bottom surface of the bolt head storage portion 25a to prevent its rotation. That is, the steel large size is maintained with the level adjusting bolt 34 locked. The upper lock nut 37 is provided with a locking prevention portion such as a locking serration 37a on the end surface of the upper lock nut 37 that contacts the bottom surface of the bolt head storage portion 25a. The lock of the level adjusting bolt 34 is maintained.) Thereafter, the lower lock nut 36 is screwed to the level adjusting bolt 34, and then the elevating nut 35 is screwed to mount the bundle body 31.
[0058]
Thus, the steel bundles 3 and 3 are attached to both ends of the bottom portion of the steel drawer 2 to complete the two-legged floor support. The steel bundle 3 may be attached to the steel draw 2 at a construction site or at a factory.
[0059]

[0078]
Thus, according to the floor structure K of this embodiment, the following merits are obtained.
[0079]
(1) Since the wood system is limited to the floor base plate material 1 and it is a structural plywood, it is possible to avoid a decrease in floor rigidity and floor noise due to thinning of the wood, warping, blow-off and the like.
[0080]
(2) The floor base material 1 is supported by a two-legged floor support device that is provided with a steel pulling 2 and a steel bundle 3 and that is sized to support the floor base material 1 having a specified width. As a result, there is no need to dispose a long large fork under the floor.
[0081]
(3) The steel draw 2 is short, and the steel bundle 3 can be easily attached to the steel draw 2 at the construction site, and its level adjustment can be done in a face-to-face operation with the opening open. Construction is also possible. From this, it can be said that it is suitable for remodeling the floor of an existing house to a barrier-free floor.
[0082]
(4) Since the large pull is the steel large pull 2 and it is a self-reinforcing type, the steel large pull 2 can be reduced in size and weight.
[0083]
(5) Since the lower part of the steel drawer 2 is covered with a heat insulating material, there is no possibility of causing a thermal bridge problem. Moreover, since the size reduction of the steel large drawing 2 is achieved, the range covered with the heat insulating material may be small.
[0084]
(6) Since a hard heat insulating material is interposed at the joint between the steel draw 2 and the steel bundle 3, there is no possibility of causing a thermal bridge problem at the joint.
[0085]
(7) Since the large draw and the bundle are made of steel and they are subjected to a predetermined rust prevention treatment, it is not necessary to perform a special rust prevention treatment or ant proof treatment in the floor construction process. Therefore, the construction is simplified and the construction period is shortened.
[0086]
(8) From the above, it is possible to improve floor rigidity, improve floor durability, reduce costs, shorten delivery time, improve construction safety, and avoid environmental pollution.
