BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight beam for preventing falling used in construction such as a house and a panel assembly using the lightweight beam.

[0002]

2. Description of the Related Art In order to prevent bending deformation of a floor plywood or a ceiling finishing material, a plurality of beams attached to the floor plywood or the like are connected to each other by using a fall prevention material for preventing fall. FIG. 7 shows a conventional anti-rolling construction method. (A) is a method of connecting the lower flanges of the beam 10 with an anti-rolling material 20, and (b) is a method of connecting the lower flange and the upper flange of the beam 10. This is a method of connecting with the non-rolling members 20 in an alternating manner, that is, in an X shape or a tape shape. In FIG. 7, 30 is a floor plywood, 40 is a beam 10 and a non-rolling material 20.
It shows the screw stop of.

However, in the conventional anti-rolling construction method, the anti-rolling material 20 for connecting the beam 10 is arranged below the lower flange or above the upper flange and is stopped by the beam 10 and a screw or the like. Since floor plywood and ceiling finishing materials are attached to the top and bottom of the beam, the anti-rolling material and the screw head become an obstacle. Further, in the method of attaching the anti-rolling material in the X shape, the anti-rolling material 20 is inserted between the beam 10 and the floor plywood 30, so that the floor plywood cannot be constructed first.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and has good workability and finishability, and prevents the anti-roll material and the screw head from interfering. An object of the present invention is to provide a light beam for anti-rolling and a panel assembly using the light beam.

[0005]

A lightweight beam for non-rolling prevention according to the present invention is a lightweight beam having a groove-shaped section or a C-shaped section with a lip, in which an opening through which the anti-rolling material penetrates is formed in the web of the lightweight beam. It has a notch to make it. The shape of the opening formed by cutting is a semicircular shape, a U shape, a groove shape, or a shape similar thereto. The lightweight beam refers to a thin steel plate or the like formed into a groove-shaped cross section or a C-shaped cross section with a lip.

If at least the cut is made as described above, since it is a lightweight cross-section material having a thin plate thickness, it can be easily bent, and if it is bent on site,
It is not bulky during transportation and does not get in the way. This notch is made in the web of the beam, and a tongue-shaped projection piece and an opening are formed by bending, so it is possible to pass the anti-rolling material through the opening and screw the anti-rolling material with the projection piece. . Therefore, since the anti-rolling material and the screw head are not on the flange of the beam, they do not interfere with the floor plywood and the ceiling finishing material. Further, since the floor plywood and the ceiling finishing material are brought into close contact with the flange of the beam, the finishability is improved.

The cuts are formed as a set at two locations near the upper and lower flanges. It is also possible to use one of the cut portions, and when the anti-rolling material is installed in parallel with the panel as shown in FIG. 7A, the cut portion farther from the panel may be used.

Further, a set of two notches at the upper and lower sides are shifted by at least one size of the opening in the longitudinal direction, and are also turned upside down. FIG. 7 (b)
When the anti-rolling material is installed in the X-shape as described above, the two anti-rolling materials are provided so as to be offset by one opening portion so that the two anti-rolling materials do not hit each other at the intersection. Further, with this configuration, the flooring work can be separated, so that the flooring work can be performed in advance.

As described above, since the mounting position of the anti-rolling member is predetermined, the workability and the mounting accuracy are good.

It is also possible to pre-assemble panels using the above-mentioned lightweight beam, and it is possible to supply the panels as floor panels, wall panels and ceiling panels. In order to meet such an application, the panel assembly of the present invention is
A plurality of light beams having a groove-shaped section or a C-shaped section with a lip arranged in parallel and penetrating each web of the light beam,
And a panel attached to at least one of the flanges of the lightweight beam.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of a lightweight beam for anti-roll of the present invention, and FIG. 2 is a sectional view. Here, the lightweight beam 1 when the anti-rolling material is installed in an X shape is illustrated. The web 11 of the lightweight beam 1 is provided with cuts 2 and 3 upside down, and openings 4 and 5 formed by bending the cuts and tongue-shaped projections 6 and 7 are provided. The opening 4 and the protruding piece 6 are provided near one upper flange 12, the opening 5 and the protruding piece 7 are provided near the other lower flange 13, and the upper and lower openings 4 and 5 are arranged in the longitudinal direction. It is provided at a position shifted by at least one unit. The protrusions 6 and 7 can be bent either inward or outward of the beam 1, but it is better to bend outward in terms of workability of attaching the anti-rolling material. The upper and lower openings 4 and 5 and the projecting pieces 6 and 7 are set as one set, and a plurality of sets are provided in the longitudinal direction of the beam 1 at intervals necessary for buckling stiffening. The number is
It depends on the beam cross section and beam length.

The cross-sectional shape of the beam 1 may be either a groove-shaped cross section as shown in FIG. 3 (a) or a C-shaped cross section with a lip 14 as shown in FIG. 3 (b). The lightweight beam 1 having such a cross-sectional shape is generally produced by press forming a thin steel plate, but the forming method and material are not particularly limited.

The notches 2 and 3 forming the contours of the openings 4 and 5 have a semicircular shape as shown in FIG.
It may be any of the U-shape of (b), the groove shape of (c), or a similar shape.

Then, as shown in FIG. 5, the band-shaped anti-rolling material 20 is passed through the opening 5, and the anti-rolling material 20 is screwed 40 to the projecting piece 7. In the same manner, another anti-rolling material is passed through the other opening 4 to fix it with screws. Fig. 6 shows an example of floor construction. One of the anti-roll members 20 is alternately passed from the upper opening 4 of the left lightweight beam 1 to the lower opening 5 of the next adjacent beam 1 and further to the upper opening 4 of the next adjacent beam 1.
The anti-rolling material 20 is screwed with each projection piece. Similarly, the other anti-rolling member 20 also starts from the lower opening 5 on the left side to the upper opening 4 of the next beam 1 and then the lower opening 5 of the next beam 1.
Alternately, and fix with screws on each protrusion.
In this way, the two anti-rolling members 20 are installed in an X shape for each beam 1, and the anti-tilting members 20 are fixed at each web portion, whereby the beams 1 can be prevented from falling. Therefore, the upper flange 12 of these beams 1
It is possible to increase the bending strength of the floor plywood 30 attached to the top, and to reduce the bending deformation. Further, since the anti-rolling material can be fixed by the web portion of the beam, flooring work can be performed in advance. Of course, the anti-rolling material can be installed in parallel with a panel such as a floor.

Since the panel is in close contact with the flange of the beam, the finishability is extremely good. Further, as is clear from FIG. 6, it is possible to use a panel assembly preassembled as a floor panel, a wall panel, or a ceiling panel. By supplying such a panel assembly, it is possible to easily construct a house or the like.

The anti-rolling member 20 has a band shape,
A wire is also possible. However, in this case, it is necessary to take another fixing method such as caulking for fixing the projection piece.

[0017]

As described above, the use of the light beam for anti-roll of the present invention has the following effects. (1) Since the non-rolling material is attached to the web part, not the flange of the beam, the non-rolling material and the screw head do not interfere with the floor panel or ceiling panel, and the panel can be closely attached to the flange of the beam. Good finish. (2) Even when the anti-rolling material is installed in an X shape, it can be fixed by the web portion of the beam, so floor work can be performed in advance. (3) Since the mounting position of the anti-rolling material is predetermined, workability and mounting accuracy are good. (4) If it has at least a notch, it can be bent at the site, is not bulky during transportation, and does not get in the way. (5) Various types and sizes of panel assemblies can be provided according to the application.
