Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICABILITY: The present invention uses a metal fitting that is buried after being inserted, so that a lattice can be rationally assembled, the assembly strength is enhanced, and the surface lattice is excellent in appearance. The present invention relates to a lattice framework structure capable of forming a frame-shaped framework.

BACKGROUND OF THE INVENTION AND PROBLEMS: Recently, in consideration of decorativeness inside and outside of buildings, lattice-like shelves and partition bodies are increasingly used. In such a lattice-shaped framework structure, it is not easy to join the intersecting portions in terms of its structure, so that it takes a lot of work to process it, and the appearance is not good. In particular, in order to align the members in a plane, a method in which one member that intersects one long member and the other member that is short are combined by means such as welding or a screw joint is used. The strength afterwards is also relatively high. In addition, it is expensive because it takes time to assemble. Furthermore, according to the conventional method, a round bar (including a round pipe) or a square bar (a square pipe) is used as a member for forming a lattice, and in the case of a square bar, it is common to arrange the planes. And has poor decorativeness.

Problems to be solved: In this way, the grid-like framework structure that has been put into practical use in the past is
What requires labor and has difficulty in improving aesthetics can be made into a simple assembly structure that significantly improves workability and has a beautiful finished appearance.
It is an object of the present invention to provide a lattice framework structure that can be used not only for partitions but also for other structures.

Structure of the Invention: In the lattice framework structure according to the present invention, a plurality of equal-length lattice component pieces are vertically and horizontally assembled so that the ridge lines of the lattice component pieces project to the surface, and The present invention relates to a lattice framework structure in which edges are joined by joints that are fitted inside the lattice component pieces, wherein the lattice component pieces have opposite ends of a square pipe-shaped trunk portion facing each other. Are formed on both sides with reference to the two ridgelines that are formed, the cutting angle is equal to the cutting angle of another adjacent grid component piece, and the tip angle is 90 °. , Having a joint piece protruding in all directions and having an external dimension that can be fitted and locked in the hollow portion of the lattice component piece,
Each joining piece adjacent to both sides of one joining piece is made to be a straight line, and the angle formed by the ridgeline of the joining piece is such that the edges of the lattice joining pieces when the lattice joining pieces are combined. It is characterized in that the angle is formed by joining them together.

It is preferable to use a square or hexagonal rectangular pipe as the lattice component piece in the present invention.

If this grid component piece is made of a material that can be molded using an extrusion die such as aluminum / aluminum alloy (synthetic resin may be used if necessary), not only a rectangular cross section but also a ridge line portion or A unique grid can be formed by integrally providing a fin-shaped rib in the adjacent portion or providing a fitting groove of a plate material that closes the grid space. In that case, a part of the rib may have a cutout pattern.

The joint in the present invention has a shape in which two rectangular rods having an outer shape that substantially matches the cross section of the hollow portion of the lattice-constituting piece are combined in such a manner that the axes of the two intersect at the center, and the ridge lines are located on the left and right sides of the top and bottom. In addition, a taper is used in the vicinity of the tip portion from the crossing to both ends so as to facilitate fitting.

This joint is formed, for example, by die-casting four joining pieces integrally, or by combining two connecting pieces with notches between the ridges in the central portion with a predetermined size at each notch, the lateral ridges of both. May be formed so as to be flush with each other, or may have a modified cross section provided with a ridge portion that engages with an inner corner of the lattice component piece, for example, a cross section of each insertion portion.

Further, in order to configure the surface lattice, when the frame body is assembled around, as a joint for inserting and locking in this portion,
Cross-section that can be inserted into the hollow part of the grid component part and that is cut in half along the axis so that the part that is inserted inside the frame is inserted into the frame component by intersecting it. A part along the ridgeline on the part side is shaved to form a step. By doing so, the frame body side can be assembled in a state where there is no open portion other than the insertion portion of the joint.

Furthermore, as a joint between the frame body and one end of the surface lattice configuration,
There is a structure in which it is formed in a Y shape, and its forked part is inserted into one side of the lattice forming part and the remaining part is inserted into the frame body.

If necessary, the joint may be made of synthetic resin.
When it is made of synthetic resin, it is preferable to use a resin containing carbon fibers and having high heat resistance, or a resin having high impact resistance such as polycarbonate resin.

Examples: The present invention is described in detail below with reference to the examples.

FIG. 1 to FIG. 8 relate to an area lattice assembled and constructed by using a square pipe, which is the most basic one.

The lattice framework structure (1) in the present invention is a lattice component (1
The square pipes used as 0) are assembled so that the ridge lines stand out, and all the lattice component pieces (10) have the same length. Both ends (11) of this lattice component (10)
When the space (2) formed between the lattices is a square shape, both sides of the reference ridges (12) and (12) are cut off at (45) at an angle of 45 degrees. Therefore, if the crossing angle θ is, for example, 60 °, one end is 30 from the reference ridge (12) line.
As for the other, use the one that is cut so that the other becomes 60 ° and the other end is cut so as to be opposite. Corresponding to the crossing angle θ, the ends 11 and 11 are formed such that the sum of the cut angles is 90 ° (see FIGS. 1 and 2). Therefore, when viewed from the side, both ends (11) (11) of this lattice component (10) are vertically
Two ridges are projected, and the ridges on both sides are cut (see FIG. 3).

The joint (20) for connecting and frame-forming the lattice component pieces (10) thus formed has a structure as shown in FIG.
According to the shape of the lattice combined by the lattice component piece (10), the joining piece (21) is integrally molded in a cross shape so that the ridge lines are joined to each other, and each joint protruding in four directions. The outer shape of the base (22) of the piece (21) is the lattice component piece to be fitted.
The connecting piece (21) has a size and shape that substantially match the inner shape of (10).
Each end (22 ') of the is shaped with a taper to facilitate insertion into the grid component (10). This joint (20) is made of aluminum, aluminum alloy, other easily moldable metal, or synthetic resin having high mechanical strength. Of course, the crossing angle θ of each joining piece (21) should be equal to the crossing angle of the target lattice.

In addition to the above integrally molded joints, as shown in FIGS. 5 and 6, a square rod-shaped connecting piece (25) of a required length is formed into a square cross section just at the center. A notch (26) is formed flat between the diagonals of the notch (26) in a section slightly wider than the dimension between the diagonals, and the tip (25 ') is left with an appropriate amount of the notch (26). Can be used as a joint (20 ') by fitting two notches (26) of such connecting pieces (25) together like the joint (20). .

When assembling the grid, the prepared grid component pieces (10)
Are joined to the joint pieces (21) of the joint (20) (or (20 ')) so that the cutting edge portions of the end portions (22') are adjacently joined. Lattice component piece (10) End part (11) is joining piece (21)
It fits into the base part (22) of the and the inner contours of both are tightly fitted, so that they are connected without wobbling, and the joint (20)
Are embedded inside the pieces (10) in a buried state. After assembling the lattice of the required size in this way, a surface lattice is formed around the lattice by combining it with the outer frame (30) prepared in advance.

For the outer frame (30) and the end of each lattice component piece (10), for example, a Y-shaped joint piece (15) is used.
The pieces (15 ′) and (15 ′) are the joint pieces (2
Same as 1) but the remaining leg pieces (15 ″)
The frame member (31) is fitted into the hole (32) provided in 1), and the frame member (31) is connected to another frame member by a well-known means by a separate fitting (not shown) at the end so as not to disassemble. A frame (30) is formed on. (Refer to FIG. 7) The grid thus assembled has a three-dimensional appearance with ridges on the surface of the grid as shown in FIG. 1 in part, and the intersections are connected by ridges. You can get beautiful things. Further, the lattice component pieces are formed by sequentially combining the short pieces by the joints to form the lattice surface. However, as described above, the joints and the pieces can be relatively tightly fitted, which is stable and By setting the outermost portion to be pressed by the frame member, the frame is integrally configured.

In addition, even when the connecting piece (20 ') is a combination of two connecting pieces (25) and (25), both connecting pieces (25) (2
The fitting portion of the notch portions (26) of 5) is sandwiched by the end portions (11) of the lattice component pieces (10) which are overlaid, and the two parts serve as joints. However, after the assembly, they are held integrally, and the lattice can be constructed without any trouble.

In addition, at a place where the frame member is to be cleaned up, for example, as shown in FIG.
Two pieces of the joint piece (17) are used so that the upper half of the ridge of the joint piece (17) is appropriately cut to form a step (17 '). ) Is a state in which the step (17 ') due to cutting is engaged with the hole (34) drilled with a predetermined pitch in the lid member (33) that fits into the member opening of the frame member (31) and does not come out. Protruding from the outer frame (30), the protruding piece (1
Assemble by assembling the lattice component pieces (10) with respect to 7). In this way, in the assembled state of the outer frame (30), no opening groove is formed between the outer frame (30) and the lattice portion, and the outer frame (30) is finished beautifully. Also, the joint piece can be easily inserted during assembly, which is convenient.

Although the lattice framework structure using a square pipe has been described above, the square pipe may be a hexagon. In this case, the flat portions are opposed to each other without the lateral portions being ridge lines. Such a shape can be arbitrarily determined. However, it is preferable that a ridge line is formed on the lattice-assembled surface.

In the obtained product, in the combined state of the joint and each lattice component piece, at each joint, the joint joint piece (connecting piece) is arranged on the core and the end faces of the lattice component pieces fitted to each other are mutually Since they are in contact with each other, they are almost integrated even if they are combined, and since the ridge lines of the lattice structure are oriented in the lattice plane direction, even if an external force is applied planarly, the lattice structure has high strength.

Next, another aspect of the present invention will be described. As shown in FIGS. 9 and 10, as the grid component piece (10 ′), a square pipe having a quadrangular cross section, in which a relatively wide rib (13) at its lateral position is projected on both sides. I'm using it. Of course, the grid component (10 ') is of a material obtained by extrusion, such as aluminum-aluminum alloy. Even in such a lattice-constituting piece (10 '), both ends are the same as in the above-mentioned embodiment, and the ribs (13) are of course used.
Also remove the part. As for the joints for the grid assembly, the same ones as described above are used.

In the lattice structure using such ribbed lattice component pieces (10 '), the space portion (3) is narrowed and a unique one is obtained. Therefore, if the rib (13) is widened and a cutout pattern is formed in a part of it, the decorativeness is further enhanced,
It will be beautiful.

Further, as shown in FIGS. 11 and 12, as the lattice component (10 ″), the groove (1
4) If two ribs (14 ') are provided on both sides at the required intervals to form 4), they will be surrounded by each grid component (10 ") when assembled in a grid. It is possible to assemble a translucent cutting plate (40) such as a synthetic resin plate or glass by fitting the periphery of the cutting plate (40) into the groove (14) with respect to the space to be formed. A highly efficient surface grating is obtained, and the assembling of the grating is the same as in the first embodiment.

With the configuration as described above, it can be used as a building material inside or outside the building.

The lattice-shaped framework structure of the present invention can also be used as a core material for articles other than building materials.

As described above, as the joint, the lattice component piece (10) (first
(Represented by the example of FIG. 13), other than a connecting piece having a rectangular cross section, as long as it has a shape that engages the corner portion when it is inserted into the hollow portion, for example, as shown in FIG. A cross-shaped joint located at the corner (2
0 ″) (for example, for a hexagon, each corner thereof, or the shape corresponding to three corners).

EFFECTS OF THE INVENTION According to the present invention, square pipes are aligned in a predetermined size, and these pipes are used as lattice component pieces to form a lattice by a joint fitted and inserted into the lattice. By connecting it so that the ends face each other as a core,
It is possible to make a strong lattice framework structure with a simple structure, and at this time, by making the ridge lines of the lattice component pieces appear on the lattice surface, it is possible to increase the strength of the lattice and dust on the surface. It is difficult to stick, and the ridgeline can be emphasized by the degree of light rays that hit the lattice surface to enhance the decorative property, and the aesthetic effect is remarkably improved, and a low-cost and useful structure can be provided.
