[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a curved structure of a frame material using channel steel, and a curved wall and a frame material using the same as a horizontal frame material.
[0002]
[Prior art]
As a means of easily constructing the upper and lower horizontal frame material of curved walls that constitute curved passages and room partitions provided in building structures, the conventional steel framing handbook [Robert Scharff and the editors of Walls & There is a horizontal frame material disclosed in P278 of ceilings magazine (1996)] (see FIGS. 7 and 8).
[0003]
The above-described prior art horizontal frame member 11 includes a grooved steel 12 and a vertical strip 14. The groove steel 12 has a notch 13 extending from the outer flange 12a to the web 12c at a predetermined interval, and the inner flange 12b is bent at the notch 13 to form a polygonal curved groove shape in plan view. Is formed.
[0004]
Next, the vertical strip 14 is applied to the inner surface of the outer flange 12a constituting the outer edge of the curved groove and joined by caulking / fastening or the like. In other words, the vertical strip 14 is bent in accordance with the polygonal shape of the outer flange 12a of the horizontal frame member 11, and is disposed in the gap between the bottoms of the triangle formed by opening the cut portion 13 of the outer flange 12a. (See FIG. 8 or FIG. 9).
[0005]
And after the vertical frame material 15 of the lip-shaped channel steel is fitted in the curved groove | channel of the horizontal frame material 11, the wall board 16 is further applied to the outer side flange 12a of the horizontal frame material 11, and a drill screw 17 and the like are joined together to form a curved wall. FIG. 10 is a longitudinal sectional view of a curved wall according to the above-described prior art.
[0006]
[Problems to be solved by the invention]
Here, according to the configuration of the above prior art, there are the following problems.
First, at the time of assembling the horizontal frame member 11, the grooved steel 12 must be bent and the vertical strip 14 must be attached. However, in order to accurately maintain the curved shape at the time of assembly, a jig or mold is used. This is necessary and complicated.
[0007]
Further, at the outer flange 12a portion (outer upper and lower end portions of the curved wall) of the horizontal frame member 11, the flange 15a of the vertical frame member 15 (grooved steel with lip), the vertical strip, from the inner side to the outer side of the curved wall. 14, the four plate members of the outer flange 12 a of the horizontal frame member 11 and the wall plate 16 overlap (see FIG. 10).
[0008]
Therefore, the outer surface of the wall plate 16 protrudes to the outside only by the plate thickness of the vertical strip 14 and the outer flange 12a only at the upper and lower ends of the curved wall, and the aesthetic appearance of the curved wall after finishing is significantly impaired. . In addition, the upper and lower end portions of the curved wall protrude, and the face material and the finishing material may be deformed or destroyed at the time of joining.
[0009]
The present invention has been made in order to eliminate the above-mentioned disadvantages of the prior art, and suppresses the protrusion of the outer surface of the curved wall plate and eliminates the need for a jig or mold for maintaining the curved shape. The object is to provide a curved structure and a curved wall and frame material using the same.
[0010]
[Means for Solving the Problems]
In the curved structure of the frame material of the first invention, the one side flange 3a and the web 3c of the channel steel 3 are cut, and the other side flange 3b is bent and bent at the cut portion, and the inner surface of the web 3c is bent. The curvature is maintained at the curvature by attaching the band plate 4 having a shape matching the curvature of the curved wall.
[0011]
The second invention is characterized in that, in the first invention, the web of the grooved steel 3 and the strip plate 4 are joined by using any one joining means of caulking, fastener or spot welding.
[0012]
3rd invention is a curved wall characterized by using the frame material in 1st or 2nd invention as the horizontal frame material 1, and suppressing the protrusion of the junction part of the wall board 8 joined to this frame material. .
[0013]
According to a fourth aspect of the present invention, a strip having a shape matching the curvature of the curved wall is formed on the inner surface of the web while making a cut on one side flange and web of the channel steel and bending the other side flange at the cut portion. It is a frame material characterized by being stacked and attached.
[0014]
<Action>
According to the present invention, since the strip 4 matched with the curvature of the curved wall 2 is overlapped and joined to the inner surface of the web 3c of the grooved steel 3 which is curved, the horizontal frame member 1 having a predetermined curvature can be easily and accurately. Can be assembled.
[0015]
Moreover, since the curvature of the channel steel 3 is maintained by the strip plate 4, a new jig for maintaining the curvature is not required, and work efficiency can be improved.
[0016]
Further, only one flange 3a is sandwiched between the vertical frame member 7 and the wall plate 8 at the upper and lower ends of the curved wall 2, and the protrusion of the wall plate 8 is suppressed as compared with the prior art ( (See FIG. 5). That is, the curved wall 2 after finishing is excellent in aesthetics, and the surface material and the finishing material are also prevented from being deformed or broken during joining.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. 1 and 2 are perspective views showing a configuration of a horizontal frame member used for the curved wall according to the present embodiment. 3 and 4 are a perspective view and a plan view, respectively, showing the assembled state with the vertical frame member. FIG. 5 is a longitudinal sectional view of the curved wall. FIG. 6 is an explanatory diagram showing a horizontal frame material when applied to a curved wall having inflection points.
[0018]
The horizontal frame member 1 is used at the upper and lower ends of the curved wall 2 (see FIG. 5), and is composed of a grooved steel 3 and a strip 4 as shown in FIG.
[0019]
The grooved steel 3 is formed by bending a thin steel plate having a thickness of about 0.5 to 2.3 mm into a groove shape, and by forming a notch 5 in one flange, and is polygonal in plan view. Are formed in a curved groove shape, and incisions 5 extending from the outer flange 3a constituting the outer edge of the curved groove to the entire width of the web 3c are put in parallel at intervals. The interval between the cuts 5 is determined in accordance with the curvature of a curved wall such as a polygonal shape. Then, the inner flange 3b is bent at the cut end and formed into a polygonal curved groove shape in contact with a predetermined curvature wall surface. It should be noted that the cut 5 is not necessary with the transition to the straight wall.
[0020]
The band plate 4 is formed such that the curvature of one or both of the inner peripheral side surface and the outer peripheral side surface is the same as a predetermined wall surface curvature. Although it does not specifically limit as a material of the strip | belt board 4, For example, the thin steel plate and the plastic board etc. which have thickness of about 0.5-2.3 mm are mentioned.
[0021]
The band plate 4 is inserted inside the grooved steel 3 so as to overlap with the inner surface of the web 3c (bottom of the curved groove), and serves as a jig (ie, a ruler) for maintaining a predetermined curvature of the curved groove. Fulfill. That is, when the strip 4 is inserted into the channel steel 3, the intermediate portion of the inner surface of the outer flange 3a and the outer peripheral surface of the strip 4 are in point contact, or the cut end of the inner flange 3b and the inner peripheral surface of the strip 4 Are point-contacted, or both the outer peripheral surface and inner peripheral surface of the band plate 4 are point-contacted to the flanges 3a and 3b, respectively, so that the curvature of the curved groove of the horizontal frame member 1 is corrected and maintained at a predetermined curvature. .
[0022]
Then, the grooved steel 3 and the strip 4 are joined by, for example, fasteners 6 such as caulking, spot welding, rivets, etc., and the horizontal frame material 1 is configured. For the upper and lower ends of the curved wall, a pair of line-symmetric horizontal frame members 1 are required, but the band plate 4 may be of the same shape.
[0023]
Next, as shown in FIG. 3, a vertical frame member 7 using a lip-shaped grooved steel formed by bending a thin steel plate is erected on the horizontal frame member 1. Here, FIG. 4 is an enlarged plan view showing a state in which the band plate 4 is joined in the curved groove of the horizontal frame member 1 and the vertical frame member 7 is further erected. In FIG. 4, a vertical frame member 7 is erected for each side of the polygon.
[0024]
3 and 4, the vertical frame member 7 is inserted into the curved groove at a predetermined interval, and the vertical frame member 7 is laterally secured together with a wall plate 8 described later by a fastener 6 such as a drill screw (FIG. 5). The frame member 1 is joined to both side flanges 3a and 3b.
[0025]
Since the stress applied to the curved wall is borne by the entire wall by the inner flange 3b and the strip 4, the strength of the curved wall is sufficiently secured.
[0026]
FIG. 5 shows a longitudinal section of the curved wall 2 with the wall plate 8 attached. The wall plate 8 on the inner surface of the curved wall 2 is not shown.
[0027]
A wall plate 8 such as a gypsum board or wood plywood having a thickness of about 6 mm is joined to the vertical frame member 7 and the upper and lower horizontal frame members 1 by a drill screw 6 on the outer side surface (large curvature side surface) of the curved wall 2. . At this time, the overlapping of the plate members at the upper and lower ends of the outer surface is three pieces, that is, the vertical frame member flange 7a, the outer flange 3a of the horizontal frame member 1, and the wall plate 8 from the inner side to the outer side. In other words, the outer surface of the wall plate 8 protrudes only for one flange of the horizontal frame member 1 and is superior in aesthetics after finishing as compared with the prior art, and the risk of deformation or destruction of the face material and the finishing material is also suppressed. The
[0028]
FIG. 6 shows a planar shape of the horizontal frame member 1 when the curved wall 2 (horizontal frame member 1) has an inflection point 9 as a modification of the embodiment. The continuity of the curved wall 2 is maintained only by switching the outer side surface (large curvature side surface) of the horizontal frame member 1 to the inner side surface at the inflection point 9. Further, when the curvature of the curved wall 2 changes with the inflection point 9 as a boundary, it can be dealt with by adjusting the curvature of the strip 4 and adjusting the interval of the notches 5 inserted into the grooved steel 3.
[0029]
In order to cope with the change in the curvature of the curved wall 2 as described above, the grooved steel 3 can be separated at the notch 5 portion to form independent groove blocks (not shown). . In this case, it is also easy to form the horizontal frame material 1 corresponding to the change in the curvature of the curved wall 2 by adjusting the curvature of the strip 4 and combining it with the groove block.
[0030]
As mentioned above, although the curving structure and curved wall of the frame material in this invention were demonstrated based on embodiment, the use of the said horizontal frame material 1 is not limited to the curved wall of a building. For example, the horizontal frame material 1 can be used as a member of an assembling-type temporary curved wall used in an exposition or the like, taking advantage of the property that a horizontal frame material having a predetermined curvature can be easily and accurately assembled. As another application, the horizontal frame member 1 can be used in a vertically or inclined state as a constituent material of a curved ceiling.
[0031]
【The invention's effect】
As is apparent from the above description, in the present invention, the band plate that is overlapped and joined to the inner surface of the curved grooved steel web also serves as a jig for maintaining the curvature of the grooved steel. Therefore, since a new jig for maintaining the curvature is not required, the construction efficiency is improved and the construction can be performed as designed, so that the construction accuracy is improved.
[0032]
Further, only one flange is sandwiched between the vertical frame member and the wall plate at the upper and lower end portions of the curved wall, and the protrusion of the wall plate is suppressed as compared with the prior art. That is, the curved wall after finishing is excellent in aesthetics, and deformation or destruction of the face material and the finishing material at the time of joining is also suppressed.
[0033]
Further, the reduction of the number of steel plates to be joined facilitates the joining work using a drill screw or the like, and the construction efficiency is improved.
