Description

The present invention relates to a proof stress unit and a proof stress panel having a honeycomb structure, and particularly relates to a proof stress unit and a proof stress panel which are lightweight, have high rigidity and strength, and are easy to manufacture. This load-bearing unit and load-bearing panel can be used for partition walls, load-bearing walls, etc. in building structures, but are not limited to this, and load-bearing units and load-bearing units that can be widely used in situations where light weight, high rigidity, and high strength are required. It is a load-bearing panel.

In conventional buildings, columns and beams or concrete bearing walls are used as bearing structures (members that bear their own weight, various loads, and dynamic external forces such as seismic loads and wind loads), and secondary members such as partition walls are used. It is treated as a member that does not bear the load. In other words, when designing the structure of a building, it is usual to design the cross section of the skeleton composed of columns and beams and bearing walls, and ignore the contribution of the secondary members such as partitions to the building bearing capacity. .. The primary reason for this is that the rigidity and strength of the secondary member is extremely low compared to the rigidity of the skeleton structure and the like.

However, even if it is a secondary member, if it is lightweight and has high strength, there are many situations where the strength can be expected by design. Especially when stable and high quality can be expected by manufacturing in the factory.

Provided is a structure in which reinforcing ribs are erected on one surface of a honeycomb panel. Again, the honeycomb panel itself is a honeycomb core composed of six flat plates, as in Patent Document 1. ..

Japanese Unexamined Patent Publication No. 5-31179 JP-A-2007-177528

The problem to be solved by the present invention is a load-bearing panel having excellent in-plane shear rigidity and strength, in-plane flexural rigidity and strength, out-of-plane flexural rigidity and strength, and being lightweight and easy to manufacture. It is a provision of a load-bearing unit having a substantially regular hexagon.

In view of the current state of the above technology, the inventor has an extremely high load-bearing capacity even though it is lightweight, easy to manufacture, and can be manufactured separately from columns and beams, and is sufficiently used as a load-bearing structure. We have invented a structure (bearing panel) that can be made and a bearing unit that constitutes it.

In the load-bearing panel, a linear steel material having a predetermined length having a C-shaped cross section (which may be called a U-shaped cross section) is divided into six equal lengths, and each web is formed in a direction in which the flange is inside. It is a panel-shaped structure whose components are hexagonal load-bearing units made by bending 60 degrees. By forming a slit in the flange from the flange end to the web at the bent portion, the flanges can be overlapped so as not to interfere with each other when the web is bent. This structure is particularly effective when the plate thickness of the flange portion is relatively small, for example, when it is several millimeters or less than about 1 mm.

It is also possible to cut a linear steel material having a C-shaped cross section at the positions divided into the six equal lengths and combine them to form a hexagonal structural unit. In this case, in the vicinity of the part where the corners of the three hexagonal structural units are matched, it is possible to shorten the work process and to fix the three structural units to each other by jigs or rivets. , It is advantageous in terms of ensuring strength.

The panel-shaped structure according to the present invention has a structure similar to the so-called honeycomb structure, but one of the features that the conventional honeycomb structure does not have is that each member has a C-shaped cross section. This feature ensures extremely high rigidity and strength, and further facilitates joining with the front plate and the back plate if necessary.

It is also possible to avoid interference between the flanges when the web is bent by providing a notch in the flange at the bending position of the web instead of the slit. By fixing adjacent webs of a plurality of hexagonal structural units to each other, the in-plane and out-of-plane rigidity and strength of the structure are significantly improved. The fixing can be performed by rivets, bolts, welding or the like. When using rivets, manufacturing is quick and easy, which contributes to shortening the process and reducing manufacturing costs.

As described above, when slits are provided in the flanges so that the slits overlap when the web is bent, fixing the overlapping flanges with rivets or the like further improves the rigidity and strength of the structure on the panel. Can be made to. When a notch is provided in the flange, it is also possible to join the notch edges of adjacent flanges to each other by butt welding or the like. Further, it can be fixed via a separately provided fixed plate (reinforcing plate).

By sandwiching the structure between flat plates (for example, a front plate and a back plate made of steel plates) provided in parallel, the strength in the out-of-plane direction (of the flat plate) is improved, and at the same time, handling is facilitated. Can be done. If the web of the load bearing unit and the flat plate are riveted, workability is significantly improved.

In addition, by setting the distance between two parallel sides of the load-bearing unit to 1/3 of the length of the short side of the flat plate and 1/6 of the length of the long length, the structure is simplified and sufficient rigidity and strength are achieved. Can be secured.

Further, if the space between the two flat plates is filled with concrete, lightweight concrete, or the like, a composite panel having extremely high in-plane and out-of-plane rigidity and strength can be obtained without using reinforcing bars.

Further, the structure on the panel (including the composite panel) according to the present invention can be used not only in a form of filling in a plane partitioned by columns and beams, but also without using columns and beams. It is also possible to construct a structural wall (bearing structure) of a building with. Furthermore, it can also be used as a floor slab by taking advantage of its high out-of-plane rigidity and strength. It can also be used as an outer wall, inner wall, partition wall, floor slab in buildings with large steel or rebar / steel concrete processing.

FIG. 14 is a diagram showing different fixed states of the load-bearing units.

Hereinafter, specific embodiments of the present invention will be described based on examples, but it is understood that the examples are merely examples and the technical idea of the present invention is not limited to the examples. Should be.

FIG. 1 shows a first embodiment of a load-bearing panel, a load-bearing unit, and a steel member thereof according to the present invention. The load-bearing panel can be used at any angle, such as not only in the vertical direction but also in the horizontal direction or diagonal direction, but here, for convenience, the short side is in the horizontal direction (X direction) and the long length is in the vertical direction (Y direction). , The following will be described on the assumption that the thickness is positioned in the other horizontal direction (Z direction). The load-bearing panel has a plurality of load-bearing units 110 in a region defined by a frame member composed of two horizontally extending horizontal members 142 extending in the horizontal direction and two vertical members 141 extending in the vertical direction.

The horizontal dimension (inner method) of the load-bearing panel 100 is exactly three times the distance between two parallel straight members 112 of the load-bearing unit 110, and the vertical dimension (inner method) of the load-bearing panel is the yield strength. It is 15 times the length of the straight member of the unit. The load-bearing unit is arranged at a position (angle) where two parallel straight members are parallel to the vertical member 141 of the load-bearing panel 100. Within the region surrounded by the frame member of the load-bearing panel, the load-bearing unit 110 having a substantially regular hexagonal shape is arranged so as to form a so-called honeycomb structure. In the vicinity of the frame member, the load-bearing unit is fixed to the frame member at the upper end and the lower end, or the top or bottom of the vertically arranged straight member.

Here, an embodiment having a dimensional relationship between the proof stress unit 110 and the proof stress panel 100 as described above will be described, but it is obvious that the dimensional relationship is not limited to the above. The horizontal dimension (inner method) of the load-bearing panel is preferably an integral multiple of the minimum outer dimension (distance of parallel straight members, outer dimension) of the load-bearing unit, but any other dimension is not a problem. There is no. The vertical dimensions of the load-bearing panel are also examples, and there is no problem even if the relationship is other than the above.

The proof stress unit 110 is composed of a straight member 112 having a C-shaped cross section (which may be referred to as a U-shaped cross section) including one web and two flanges. That is, although not limited to this, for example, a long member 111 having a C-shaped cross section is cut at a position where it is divided into six portions having the same length, and a straight line is formed so that the flange is on the inside. The member can be manufactured by bending at the cut portion of the flange (that is, by bending the web). When bending the web, the flanges may interfere with each other, but if the flanges are thin, the mutual interference does not become a major obstacle and the flanges can overlap with each other.

By fixing the overlapping portions of the flanges to each other, the proof stress unit 110 becomes a strong unit having a substantially regular hexagon. For the fixing, means such as rivets, bolts and nuts, and welding can be used, but fixing by rivets is excellent in terms of workability and fixing strength. On the other hand, fixing with bolts and nuts has an advantage that the fixing strength can be adjusted or tightened even after the manufacturing process of the load-bearing unit or the load-bearing panel or the start of use. Welding and the like are characterized by fixing without loosening. In the following description, fixing using rivets will be described for simplification of the description, but it is obvious that the other fixing method may be used.

The straight member of the load-bearing unit has a C-shaped cross section, the web defines the substantially regular hexagonal outer shape of the load-bearing unit, the flange extends inward of the substantially regular hexagonal outer shape, and the distance between the two opposing flanges. Defines the thickness of the load bearing panel.

The load-bearing units are assembled so as to form a honeycomb structure as a whole by fixing the webs to each other. Fixing of the load-bearing units to each other can be performed directly or via a reinforcing plate by using techniques such as rivets, bolts and nuts, and spot welding. The advantages and effects of each fixing method are as described above. The fixing is preferably performed in the vicinity of the position where the tops of the three load-bearing units are mated, but of course, the fixing can be performed at an intermediate position between the tops or both. Further, by applying a reinforcing plate parallel to the flange to the fixed position and fixing the flange together with the plate, the fixing between the load-bearing units can be further strengthened.

The load-bearing unit and the frame member can be fixed in the same manner as the fixing of the load-bearing units to each other. However, if the thickness of the portion of the frame member for fixing the load-bearing unit is large, a reinforcing plate parallel to the flange should be used. It is possible to relax the stress concentration and suppress the decrease in rigidity and strength due to the shape of the fixed portion.

The load-bearing unit configured as described above has a very high rigidity and strength for its weight because the web is an integral structure through six straight members and the flanges are overlapped with each other and fixed to each other. It constitutes a strong structure. Further, the load-bearing panel composed of such a load-bearing unit is also a strong structure having extremely high rigidity and strength for its weight. This high rigidity and strength is of course with respect to the in-plane load, but in particular, due to the structure in which the flange of the straight member defines the thickness direction of the load-bearing panel, the rigidity with respect to the out-of-plane load Very high strength.

FIG. 2B is a magnified view of the proof stress unit 110. The six straight members 112 form a substantially regular hexagonal proof stress unit 110. The flanges 114 of the straight member 112 are partially overlapped with each other and fixed to each other by rivets 116. Further, the adjacent load-bearing units are in contact with each other with the webs, and the webs are fixed to each other by rivets 116.

FIG. 2A shows a long member 111 before manufacturing the six linear members 112. The web of the long member 111 having a C-shaped cross section (U-shaped cross section) composed of one web and two flanges is formed with notches at five places so as to define six straight members.

FIG. 2C is a diagram showing a state in which the proof stress units 110 are fixed to each other. The flanges of the straight members 112 and 112'are fixed to each other by the rivets 116 at the overlapping portion, and the webs of the adjacent straight members 112 and 112' are fixed to each other by the rivets 118.

FIG. 3 shows a linear member 122 different from the above and a method of fixing the linear member different from the above. FIG. 3C shows a straight member 122 in which the end portion of the flange is cut out so that the flanges of adjacent straight members do not overlap when the straight member 122 is assembled into the load-bearing unit. At this time, the web portion may be one in which six webs are composed of one long member, or each straight member including the web may be independent. The cross section of the straight member 122 is C-shaped 122'or U-shaped.

The straight member 122 can be fixed to each other by applying a reinforcing plate 124 to the top of the load-bearing unit and fixing each web to the top of the bearing unit in FIG. 3A. Further, FIG. 3B. As shown in, the load-bearing units can be fixed to each other by applying a reinforcing plate to the part of the web and fixing the web to the reinforcing plate.

FIG. 4 is a diagram showing a long member 211 having a notch so that the flanges do not overlap each other. As mentioned above, the webs may be continuous with each other, and the webs may also be disconnected from each other.

FIG. 5 is an enlarged view showing the fixing of the load bearing unit and the frame member. It is self-evident that the proof stress unit fixed to the frame member is not necessarily a substantially regular hexagon, but may be a part of a substantially regular hexagon as shown in FIGS. 5 (a) and 5 (b). is there. At the other end, the straight member 146 fixed to the horizontal member is fixed to the straight member 112 of the adjacent load-bearing member. The straight member 146 and the other straight member 148 to which the webs are fixed are shorter than the other vertical members in terms of the positional relationship with the frame member.

FIG. 5B is an enlarged view showing an example of the structure when the load-bearing unit is fixed to the corner of the frame member.

FIG. 6 is a diagram showing a proof stress panel 200 in which the proof stress units are fixed to each other differently from the above. In the embodiment shown in FIG. 6, the adjacent load-bearing units are mutually fixed and reinforced by the reinforcing plate 242 having the shape shown in the figure. The reinforcing plate fixes the flange, but the web can be fixed to each other directly with rivets, fixed to each other using the reinforcing plate, or further fixed by other methods. is there.

The embodiment shown in FIG. 7 is different from the above embodiment in that the flanges of the load-bearing unit 310 are fixed to each other by one rivet 316.

FIG. 8 shows an example in which the dimensional relationship between the proof stress unit and the proof stress panel is different from the above example. The horizontal direction of the load-bearing panel is three times the distance between the straight members (outside distance) of the load-bearing unit as described above, but the length in the vertical direction is large, and 22 substantially regular hexagonal load-bearing units are accommodated. The horizontal and vertical dimensions of the load-bearing unit can be manufactured if it is an integral multiple of the horizontal and vertical dimensions of the load-bearing panel, or a relatively sharp multiple (2.5 times, etc., including fractions). It's easy, but it doesn't have to be that way.

FIG. 9 shows a method of fixing the load-bearing unit and the load-bearing panel, which is also different from the above. According to the load-bearing panel 360 shown in FIG. 9, a flange for attaching the load-bearing unit is provided inside the frame member, and the load-bearing unit is fixed to the flange. With such a configuration, it is possible to use a member having a square cross section or the like, which is a little difficult to attach the load-bearing unit to the frame member.

FIG. 10 shows an embodiment in which the bearing units are fixed to each other differently from the above. The load-bearing unit 362 is composed of straight members fixed to each other via a reinforcing plate at the top, and each flange and the reinforcing plate are fixed by two rivets. It is obvious that the optimum number, position, etc. of the number, fixing position, thickness, etc. of rivets should be determined based on the dimensions such as the thickness, size, etc. of the flange.

FIG. 11 is an enlarged view of a further different structure for fixing the proof stress units 364 to each other. The position of the rivet is different from the above-mentioned fixing method. The webs are also fixed to each other by rivets.

In the load-bearing panel 400 shown in FIG. 12, the load-bearing unit is fixed to the vertical member at the top of a substantially regular hexagon, and the straight member is in contact with the horizontal member, which is different from the above embodiment.

FIG. 13 shows Example 500 in which the load-bearing panel composed of a plurality of load-bearing members has a substantially regular hexagon as a whole. Here, too, the structure itself of the load-bearing unit 510 is the same as the above-mentioned structure except for the portion fixed to the frame member of the load-bearing panel.

FIG. 14 shows a load-bearing panel 550 whose fixing method to the frame member is different from that of the above-mentioned person.

It goes without saying that the load-bearing panel according to the present invention can be used as a partition wall, a load-bearing wall, an interior material or an exterior material in a building, but it can also be used as a floor slab by utilizing the high out-of-plane rigidity of the same structure. Furthermore, it can be used in various structures that are required to be lightweight, have high rigidity, and have high yield strength, in addition to buildings. Examples are hull structures, flying objects, various housings, etc., but are not limited to these.
