Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a steel-drawn steel for supporting a floor joist of a house or the like, a support structure for a steel-drawn steel, and a support method.
[0002]
[Background technology]
In general, in a house, a wooden fork is used to support a joist on the first floor. However, in recent years, it has become difficult to stably supply timber, and for this reason, making a large amount of steel is partly performed.
As a technique using steel pulling, for example, those described in Japanese Patent No. 2750273 and Japanese Patent No. 2828240 are known. The steel pullings described in these publications are made of pipe material having a square cross section and are supported on a bundle base via a steel bundle. This steel bundle is constructed by connecting a large acceptor having an L-shaped cross section and a base plate with a turnbuckle, and in order to mount a steel draw on the large acceptor, the large acceptor The bottom wall and side wall of the steel steel are brought into contact with the bottom wall and the side wall of the steel plate, respectively, and bolts, nails, etc. are removed from the holes formed in the bottom wall and the side wall of the large retractor. It is done by screwing or driving into a steel draw.
[0003]
[Problems to be solved by the invention]
By the way, the steel pulling described in the above-mentioned Japanese Patent No. 2828240 is formed in a cylindrical shape having a substantially inverted trapezoidal cross section, and thus has the following problems.
That is, the steel pulling is supported by a receiving portion provided at the upper end of the steel bundle, and when the steel pulling is attached to the receiving portion, the steel pulling and the receiving portion When a gap is generated between the side plate and the steel plate, the steel plate is rattled in the receiving portion and the support of the steel plate is unstable.
[0004]
In order to eliminate the gap as described above, the width of the lower end of the steel pulling is made approximately equal to or slightly larger than the distance between the side plates of the receiving part, and the lower end of the steel pulling is made to be It is only necessary to push between the side plates, but the steel pulling is formed into a cylindrical shape having a substantially inverted trapezoidal cross section by bending the steel plate, so the lower end of the steel pulling Is difficult to finish to a size that can be securely fitted between the side plates of the receiving part, and if the lower end of the steel pull is larger than the above size, the lower end cannot be fitted between the side plates. Or, if the force is pushed in force, an excessive force may be applied to the steel pull and the steel pull may be deformed or damaged. When it becomes smaller, a gap is generated between the lower end portion and the side plate of the receiving portion.
Further, the steel fore is formed by bending the steel plate into a cylindrical shape having a substantially inverted trapezoidal cross section, and staking both ends of the steel plate at the center of the lower surface thereof. There was also a problem that this caulking process took time.
[0005]
In addition, when supporting the steel pulling described in Japanese Patent No. 2750273 and Japanese Patent No. 2828240, a plurality of locations in the length direction of the steel pulling are each supported by a steel bundle. In this case, it is necessary to attach a predetermined portion of the steel overhang to each of the steel underbrushers of the steel bundle, but as described above, when attaching the steel overbrower to the overdrawer, Since it is necessary to screw or drive bolts, nails, etc. into the steel puller from the holes formed in the bottom wall and the side wall of the large receiver, it is troublesome. There was a problem that it took a lot of time and effort to wear.
[0006]
The present invention has been made in view of the above circumstances, and can be easily and reliably supported by a steel large-quoted floor bundle, and can be easily manufactured. It is an object to provide a support structure and a support method.
[0007]
[Means for Solving the Problems]
  In order to achieve the above object, the steel pulling 1 (51, 81) according to claim 1 of the present invention has a floor (floor panel 30 as shown in FIG. 1 (FIGS. 12 and 16) and FIG. 2, for example. For supporting joists (crosspiece 30a),
  Hollow steel pulling body 2 (52),
  An opening 8 formed continuously from one end to the other end along the longitudinal direction of the steel pulling main body 2 (52) on the lower surface of the steel pulling main body 2 (52). (58) and,
The opening 8 ( 58 ) On both sides of the steel pulling body 2 ( 52 ) Standing perpendicular to the lower surface of the steel, ( 52 ) Standing wall 8a formed continuously along the longitudinal direction of ( 58a ) WhenIt is equipped with.
[0008]
The steel pulling body 2 (52) may have any cross-sectional shape as long as it is hollow, but for example, a square shape, a rectangular shape, a trapezoidal shape, or other polygonal shapes are desirable. It is desirable that the upper and lower surfaces 2a, 2b (52a, 52b) of the large drawing body 2 (52) are planes parallel to each other.
[0009]
In addition, as for the steel pulling 1, 51, 81, for example, as in the steel pulling 1, the width of the upper surface 2a of the steel pulling main body 2 is set larger than the width of the lower surface 2b. Good.
In order to set the width of the upper surface 2a of the steel pulling main body 1 to be larger than the width of the lower surface 2b, for example, the cross-sectional shape of the steel pulling main body 2 may be an inverted trapezoidal shape. The cross-sectional shape of the steelmaking main body 2 may be an irregular polygon shape whose upper side is longer than the lower side, and may be any shape as long as the upper side is longer than the lower side.
[0010]
As described above, if the width of the upper surface 2a of the steel pulling main body 2 is set larger than the width of the lower surface 2b, the joists (crosspieces) of the floor (floor panel 30) are supported on a wide surface, and thus stable. The floor is supported. Further, when the floor is composed of floor panels 30 used in the panel construction method, at the place where the floor panels 30 are arranged, the two adjacent floor panels 30 and 30 are received by one steel draw. However, by setting the width of the upper surface 2a of the steel pulling main body 2 to be larger than the width of the lower surface 2b, a large allowance for the steel pulling 1 of each floor panel 30 can be obtained.
Furthermore, the lower surface 2b of the steel pulling main body 2 only needs to be able to transmit a load to the steel large quote floor bundle 10. Therefore, it is not necessary to increase the width of the upper surface 2a, and the material can be saved by reducing the width. Can do.
