Description of the Related Art A conventional floor bundle support has a structure in which a substantially L-shaped receiving plate and a base plate are connected by a turnbuckle pipe in a side view as seen in, for example, Japanese Utility Model Registration No. 3031622. Is common. In this floor bundle supporter, a male screw part in a normal direction and a female screw part formed in the both ends of the pipe body is provided with a male screw part in a normal / reverse direction, which is suspended and erected so as to face a receiving plate bottom side and a base plate surface side. After screwing and connecting to each other, fix the base plate on the slab, and rotate the pipe body to reach the length from the base plate to the receiving plate,
That is, it is formed so as to adjust the height of the floor bundle. After adjusting the height, tighten the nuts previously screwed into each male thread part to both ends of the pipe body and fix them, and fix the large pull placed on the receiving plate using nails etc. By doing so, it is possible to prevent the misalignment between the pulling and the floor bundle support.

されている。[0003] The pipe body of the floor bundle support is formed with a thick middle portion from the viewpoint of making it easy to rotate by a tool such as a wrench, and ensuring load resistance. On the other hand, both ends of the pipe body where the female thread is formed are narrowed down to a small diameter according to the diameter of the male screw part on the receiving plate and base plate side. There is a drawback that equipment is required or productivity is reduced due to an increase in drawing load of a mold or a press machine. Therefore, as shown in, for example, JP-A-9-119415, the outer peripheral surface is partially pressed so as to bulge and form a plurality of protrusions on the inner peripheral surface of the upper and lower internal thread portions of the pipe body, and the diameter is reduced to a small diameter. It has also been proposed to improve productivity by doing so.

で、耐荷重性能が低下する問題が指摘されていた。The compressive load applied to the floor bundle support is applied to both end surfaces of the pipe body through nuts screwed into male threads of the receiving plate and the base plate. In the case of a pipe with a bent shape, it is pointed out that the nut has a small diameter at both ends, so that the seating of the nut is poor, and since both ends of the pipe can be supported only near the inner peripheral edge of the nut, the load bearing performance is reduced. Was.

より抜けてしまうという新たな問題点を有していた。On the other hand, in the floor bundle support described in JP-A-9-119415, the remaining outer peripheral surface which is not pressed when a plurality of protrusions are formed on the inner peripheral surface at both ends of the pipe body is large. Since the nut can be supported with the same diameter, it exhibits superior compressive strength compared to the conventional product, but on the other hand, the female screw portion is easily expanded outward due to its cross-sectional shape and easily deformed. Since the portion where the thread groove can be cut on the peripheral surface is limited to only the protrusion, there is little engagement with the male screw, so when a large tensile load is applied to the entire floor bundle support, the receiving plate And the base plate comes off from the pipe body.

なくなってしまうのである。Further, when the upper and lower female threads at both ends of the pipe are narrowed to a small diameter, a surplus occurs in the material, and the excess material escapes toward the end face of the female thread. There was a disadvantage. In particular, in the floor bundle support described in JP-A-9-119415 described above,
Since the outer peripheral surfaces of both end portions of the pipe body are partially pressed to reduce the diameter, the unevenness from the non-pressed portion appears remarkably. If the nut provided on the male screw part of the receiving plate or base plate is tightened against both ends of the pipe body where the unevenness has occurred, the nut naturally tends to incline along the end face, so between the female screw and the male screw The male screw part is fixed in a tilted state, albeit slightly, by the amount of the fitting gap existing in the floor, so an eccentric load acts and exhibits the load bearing performance that the floor bundle support originally has You will not be able to do it.

向上するのである。[0010] In the floor member support device constructed as described above, the nut screwed into the male screw portion of the receiving plate or the like is securely fastened to the horizontal flange portion at the end of the pipe body. The plate and the like are fixed in a straight state without being inclined with respect to the axis of the pipe body. Such a horizontal flange portion is press-pressed from the edge direction of the upper and lower female screw portions when forming the upper and lower female screw portions by squeezing the end of the pipe body to a small diameter, so that the pipe body has an accuracy that is straight to the pipe body. It is formed as a flat surface having a high level. Therefore, as a result of the load direction coinciding with the axis, the load-bearing performance inherent in the floor member support is exhibited. Furthermore, since the horizontal flange also functions as a rib to reinforce the pipe body end,
In addition to preventing the pipe body end from deforming and expanding when a tensile load or bending load is applied between the upper and lower female threads and the male threads, compared to the case without a horizontal flange,
By increasing the contact area between the pipe body end face and the nut, the nut is less likely to be loosened. Further, the nut can be supported at a position farther from the axis, so that the horizontal load resistance is improved.

Therefore, even if the thickness of the pipe body is reduced, the diameter is reduced, or the diameter of the male thread is reduced, the same strength as the conventional product can be secured.
The formation of the horizontal flange also contributes to a reduction in manufacturing costs.

重性能にも優れた床部材支持具とすることができる。The plurality of ridges formed on the outer peripheral surface of the upper and lower female screw portions provide reinforcement when a bending load is applied to the end of the pipe body. The presence of the ridges allows the nut to be further distant from the axis. A stable tightened state is realized by being supported. Such a ridge on the outer peripheral surface of the upper and lower female screw portions can be formed by drawing, but by being completely folded so as not to leave a gap in the ridge, it is almost continuous with the inner surfaces of the upper and lower female screw portions. A secured peripheral surface can be secured. As described above, although a substantially continuous female screw can be screwed around the entire inner surface of the upper and lower female screw portions despite the provision of the ridges, a floor member support having excellent tensile load performance can be obtained. it can.

条として残した。In the invention described in claim 4, a square pipe material is used for the pipe body of the floor member support, and the upper and lower female screw portions of the pipe body are arranged in the longitudinal direction from the edge on the outer peripheral surface thereof. A plurality of extending ridges were formed at appropriate intervals in the circumferential direction, while a substantially continuous circumferential surface was formed on the inner peripheral surface, and a portion corresponding to a corner of the square pipe was left as a ridge.

る利点が得られる。For the square pipe material, it is difficult to draw a small diameter and it is also difficult to form a thread groove on the inner peripheral surface.
Conventionally, it has not been used as a pipe for a floor member support. In the present invention, a square pipe material can be used as a pipe body by drawing in such a manner that a convex portion is formed at the corner. When a round pipe material is used as the pipe body of the floor member support, a tool fitting portion having a polygonal cross section is formed in the middle of the pipe body by a separate process from the forming of the upper and lower internal thread portions by drawing. However, if a square pipe material is used, there is an advantage that the entire intermediate portion of the pipe body can be used as a tool fitting portion as it is.

If the chamfered portion is formed, the burrs generated when the inner peripheral surface of the upper and lower female screw portions are threaded are not exposed outward from the leading edges of the upper and lower female screw portions, so that the deburring operation after the screw processing is omitted. You can do it.
