Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plurality of elongated aluminum extruded shapes intended to be used in combination, and which can be used for structures such as buildings, temporary materials, or fixtures. With,
The present invention aims to provide a combination material that can be applied to interior materials, efsteria bar materials, poles, supports, etc.

There is no need to point out that aluminum shapes are widely used for the above-mentioned purposes, but conventional ones are often simply long materials with a cylindrical or square tube shape, and their outer diameter ( No particular consideration was given to the outer diameter (outer diameter) dimensions and the inner diameter (inner diameter) dimensions.

Therefore, unless the members were of the same dimensions, they could not be assembled smoothly, and the only way to assemble them was to use a limited number of materials.

Other conventional long materials have cross-sectional shapes as shown in Figure 1.
As shown in E, the inner surface may have ribs protruding in the longitudinal direction, or the outer surface may have radial ribs.
Various shapes have been considered, such as a ``chiaki'' cross section, but there is no example of using a unified standard cross section in combination. No attempt has been made to make it possible to combine elongated materials with different inner diameters on both the inner and outer surfaces.

Hereinafter, this point will be explained in detail based on Fig. 2. For example, when manufacturing a frame like the one shown in the figure using aluminum shapes, pillars A, A, base opening, d1 horizontal frame C, B, and mound pillar 2. There is a demand for components such as those having standard dimensions that are uniform in external shape even if there are differences in cross-sectional dimensions.

This is because if this were realized, the mutual compatibility of the components would increase, and the aesthetic appearance of the framework itself would also be enhanced.

Also, if you want to make the lower part of one pillar thicker and the upper part thinner for strength reasons, and keep the external shape of the pillar the same for aesthetic reasons (in such cases, custom-made products have traditionally been used). If this can be achieved with standard products,
Its industrial effects are significant.

Furthermore, when using these types of extruded aluminum shapes in combination, it is inevitably necessary to connect each shape, but in such a case, a connecting tool is fitted inside each shape, and a connecting tool is inserted through this connecting tool. It is extremely desirable from the viewpoint of strength and aesthetics to connect the respective shapes, and such a joining means is also widely used.

However, when fitting a connector into a mold, the inner diameter (inner dimension) of each mold must be at least a standardized cross section, in other words, a certain space must be formed in the effective inner diameter.
It is not possible to make connections using connectors.

Especially when the outer shapes of the pieces to be connected are different from each other,
It would be very convenient if they could be connected using a standardized connector.

As described below, the present invention unifies the inner diameter (inner diameter) dimensions of each shape material, making it possible to use a certain standardized connecting tool, and thereby making it possible to use various combinations of shape materials in terms of connecting tools. This was an attempt to solve all the problems that had been restricted in one fell swoop.

As described above, the present invention aims to provide a standardized mold material that satisfies all of the above-mentioned various technical requirements imposed on mold materials, and in which the inner and outer diameter dimensions have a fixed relationship. It is something.

That is, the present invention maintains a specific relationship between the outer dimension and inner diameter of one of the plurality of hollow elongated shapes to be combined, and also maintains this relationship for the other shapes to be combined. so that the outer dimensions and inner diameter dimensions of the mold materials to be used in combination are all in a common relationship,
This is an attempt to solve the above technical problems all at once.

More specifically, the present invention is directed to an aluminum profile having a square or rectangular cross section with ribs formed on its inner surface, and of two sets of opposite sides of the profile, one opposite side and the other opposite side. First, each length and outer diameter on the outside are set using an arbitrarily selected square as a reference, and are set to be equal to the length of this reference square, or to be a natural multiple of this length.

Incidentally, when the lengths of the two pairs of opposite sides are the same, the resulting shape is a square, and when the lengths of one opposite side and the other side are different, the resulting shape is a rectangle.

From the viewpoint of industrial implementation, the dimensions of the reference square are such that its negative side is 10 squares or more.

According to the present invention, the thickness of each side of the mold material is determined as follows.

In other words, among the two sets of opposite sides, the thickness of one opposite side is the length of the other adjacent opposite side multiplied by a certain ratio k, and the thickness of the remaining opposite sides is determined in the same way. Its thickness is determined by multiplying the length by the same ratio k.

The above ratio is determined by considering the strength and usage of the mold material, but specifically it is 5/1.
It may be arbitrarily selected from the range of 00≦≦1/1o.

The higher the k value, the thicker the wall, and the higher the strength of the shape.

Note that this value must be used in common for all the plurality of mold materials to be combined, but it goes without saying that different values may be used for different combinations.

Furthermore, in order to maintain the wall thickness determined in the manner described above, the actual wall thickness of the shape material, in other words, the net thickness, is not maintained at the set value; Let the wall thickness be the apparent wall thickness.

That is, a material having ribs formed on its inner surface is used as a material, and the apparent thickness is the sum of the height of the ribs and the net thickness of the material on which the ribs are formed.

If the actual wall thickness of the mold material were adjusted to the set value, a large amount of material would be required and the weight would also increase.In order to avoid this, in the present invention, the inner surface of the mold material is hollowed out to form ribs. The apparent wall thickness, in other words, the wall thickness that does not impede the object of the present invention is formed.

In this way, materials can be saved and the weight of the mold material can also be reduced.

Not only that, but it also has the advantage that the net thickness of the profile can be adjusted as desired without changing the apparent wall thickness.

By the way, in the present invention, when combining shapes having the outside diameter and wall thickness determined as described above, there is no problem even if the shapes having the same outside diameter or wall thickness are combined. The effect will be better when materials with different outer diameters or wall thicknesses are combined.

That is, even when molds having different outer diameters and wall thicknesses are combined, the mutual matching relationship between the molds is maintained.

Furthermore, when connecting the assembled shapes to each other, it is sufficient to use at least one internal connector, and there is also the advantage that the connector is not exposed on the surface.

The present invention will be specifically described below with reference to embodiments shown in the drawings.

First, the elongated material with a square cross section shown in FIG. 3 will be described.

- As an example, select a 25 square square as a reference and determine its wall thickness as follows.

That is, if the length of one side in the outer diameter dimension is D, the wall thickness is set as a value obtained by multiplying the above value by a certain ratio k, and the value in this case is 6/100 as an example.

As mentioned above, this value is approximately 5/100≦≦1/10
There is no practical problem if it is within the range of , and the selection should be made taking into consideration strength and usage.

For example, when the shape material of the present invention is used as a bar material for the interior of a building, the value of k adopted in the group of shape materials may be about 6/100, since so much strength is not required.

In addition, when used as a structural material, the value is set to 1/1 to determine the apparent wall thickness of the shape material group in order to obtain strength.
Set to about 0.

Further, in the present invention, since ribs 2 are formed on the inner surface of the mold material 1 as shown in the figure, if t is the net thickness of the mold material on which the ribs are formed, then the rib 2 is Let T be the thickness plus the height of , and let this T be the apparent thickness of the mold material.

Therefore, the wall thickness T is determined by T=-D, so T=6/1
00X2! Mm=1.5mm.

In this case, the inner diameter dimension d, that is, the dimension of the square hollow part formed by the line connecting the tips of the ribs, is d=D
-2T, so d = 2! Mm-2X 1.5 = 22mm.

By the way, in the case of the square shaped material shown in Figure 3, the two pairs of opposite sides have the same length, so when determining the apparent wall thickness T, there is no need to consider the lengths of adjacent sides; It can be calculated by multiplying by a constant ratio k.

In addition, when the length of one side of the reference square is 25 mm, the apparent wall thickness T and inner diameter dimension d of a square aluminum profile whose sides are natural multiples of 50 mm, 75 mm, and 1007 Wffl are calculated in the same manner as above. , as shown in Table 1.

The relationships shown in the above table are shown in drawings as shown in the drawing numbers in the right column of the table. By doing this, all the shapes with the dimensions shown in the above table can be closely connected to each other while maintaining a consistent relationship. I can do it.

Note that Fig. 3 shows an example in which the outer surface of the molded material is made flat without any protrusions, and the ribs 2 are provided only on the inner surface.
Various treatments may be applied to the outer surface as long as it does not prevent decorative lines or carved patterns 3 as shown in FIG. 4 as shown in FIG. can be applied.

Further, a large number of ribs 2 may be provided at equal intervals as shown in Fig. 4, and at rib intervals common to multiple shapes to be combined, but at least one rib is present on the inner wall of each side. It's enough.

In some cases, the shape may be as shown in FIGS. 5A to 5C.

Next, the case of a rectangular cross section will be explained.

In this case, when the outer diameter of one of the two pairs of opposite sides is D, and the outer diameter of the other pair of opposite sides (i.e., the other adjacent side) is the same, the dimensions of D and length are , is a natural multiple (a multiple of a natural number including 1) of the outer diameter dimension of a reference square that is arbitrarily determined in common to the group of combination shapes.

FIG. 6 shows a comprehensive diagram of these relationships.

The reference square in the case of FIG. 6 is the smallest square in the figure, and its outer diameter is the same length as both D and U.

In this case, as shown in the figure, the short side and long side of each rectangular shaped member are in a relationship that is an integral multiple of the length D and length of the outer side of the smallest reference square.

FIG. 1 shows a detailed example of this. Even in this group of rectangular shapes, the relationships among the outer diameter and D', and the apparent wall thicknesses T and τ are the same as in the case of the group of square shapes described above. .

In other words, the outside diameter of the short side (the side adjacent to the long side, i.e., the other pair of opposite sides) is calculated by multiplying the above ratio k by do.

Expressed by the formula *T'=kD.

On the other hand, the apparent wall thickness T of the short side is the outer diameter of the long side (the side adjacent to the short side) multiplied by the ratio k, and T =
kD'.

Specifically, the short side length D is 50 mm, the long side length D' is 100 m1lI) The rectangular shape material is a group of rectangular shape materials composed of natural multiples of a standard square with an outer diameter of 25 myn. If the ratio k is 6/100, the apparent thickness is T=6/100XI 00=6T'=6/10100X50=3.

Thereafter, in the same manner, a group of shapes having a rectangular cross section as shown in the table below is obtained.

As is clear from Tables 1 and 2, when looking at the outer diameter, inner diameter, and apparent wall thickness of the group of shapes having square and rectangular cross sections illustrated here, the outer diameter of each shape is composed of natural multiples of a reference square with sides of 25 mm, and all apparent wall thicknesses are the lengths of adjacent sides at a ratio of 6/1 arbitrarily adopted from the above range.
The value is multiplied by 00.

Therefore, since the inner diameter dimension in this case is also a natural multiple of a square with sides of 22 squares, a standardized connector (see FIG. 15) as described later can be used.

In this way, in the group of shapes of the present invention, the outer diameter dimension and the circular dimension are integer multiples (multiples including l) of the length of one side of the common reference square.
Not only when these shapes are brought into abutment on their outer surfaces, but also when another shape material is fitted onto the inner diameter of the shape material, it fits tightly and is highly effective as a combined shape material.

In other words, it is possible to create any combination of shapes selected as needed from among the shapes having the cross-sectional shapes standardized as described above, and this makes it possible to achieve versatility and economy that cannot be expected with conventional methods. Demonstrate.

Furthermore, since the shape material of the present invention uses a material with ribs formed on the inner surface, once the apparent wall thickness is set as described above, the ribs are next set within the range of this apparent wall thickness. Another advantage is that the height and net thickness can be adjusted relatively.

In other words, it is possible to select a value from a wide range considering the usage and strength of the material, and once the value has been selected, the rib height and net thickness can be compared relative to each other without changing the apparent wall thickness determined by the value. Therefore, the shape material of the present invention exhibits adaptability suitable for the purpose when used as a structural material or as a ball material for interior and exterior use.

In general, it is best to use the one with the larger net thickness for structural purposes from among a group of shapes with the same apparent wall thickness, and use the thinner one as auxiliary material or interior/exterior material.

Incidentally, the shape of the rift for forming the apparent wall thickness T is not limited, and in addition to the above-described embodiments, the shape shown in FIG. 8, for example, may be used.

The rib in this case is composed of a protrusion 2 similar to that described above on the inner surface of the net thickness portion 4 of the profile 1, and an overhang member 5 at the corner.

In the present invention, the ribs 2, protrusions 2', or overhanging members 5 may be formed by cutting off a portion of the inner surface of the mold material, but generally the mold material is formed by pressure molding using a predetermined die. By manufacturing this, it is possible to provide a shape material having desired ribs, protrusions, etc. very easily.

Next, the case of interconnecting the mold members according to the present invention will be explained.

As already mentioned, the combined shape material of the present invention has a fixed relationship between its outer diameter and inner diameter, so that it exhibits the following advantages when connecting the shape materials to each other.

In other words, as shown in Table 2, the dimensions of the hollow part formed on the inner surface of the combined profile maintain a multiple relationship of the common reference square, so the connector used by inserting into this hollow part can also be , which is advantageous in that it can be standardized.

Incidentally, although the present invention does not necessarily require the use of standardized connectors, it is desirable for industrial implementation to standardize connectors as well, and this invention made this possible. It is an invention.

These points will be specifically explained below based on FIGS. 9 to 15.

Incidentally, this example is an enlarged sectional view of the joints of the respective shapes when the framework shown in FIG. 2 was manufactured.

First, referring to FIG. 9, a case will be described in which a connecting tool 6 having a square cross section is used to connect the lower column A and the upper column A' in the framework on the same axis.

The wall thickness of the lower column A is larger than that of the upper column A' due to strength considerations, but the apparent thickness as an outer diameter does not change at all.

In order to save materials by making the columns have different strengths, and to assemble a predetermined frame without changing the appearance, it is necessary to connect these shapes internally.

In this case, according to the present invention, since the inner diameters of the upper and lower columns A and A' having different strengths are the same, a simple member 6 with a square cross section can be used as the connector (this is not shown in the figure). It is sufficient to fit it in the axial direction of the shape material as shown in the figure, and then secure it with screws 7.8, etc.

This also applies when the shaped material of the present invention is used for poles, retaining wall supports, etc.

As described above, according to the present invention, when setting beams, columns, etc., it is possible to keep the outside dimensions the same, and to divide and use sections with wall thicknesses depending on the required strength. Since the dimensions of the inner diameter portion are the same, the same connector can be used as is even if the type of mold material changes.

Figure 9 shows columns A with the same outer diameter but different wall thicknesses. In addition to showing an example of semi-connecting columns A and A', it also shows a case where horizontal frames C and H' having different outer diameters are connected to the columns A and A'.

That is, the cross-sectional shape of the horizontal frame indicated by symbols C and C' in the same figure is as shown in FIG. has been done.

In this case, as is clear from the figure, when comparing the upper horizontal frame B and the lower horizontal frame C, the net thickness of the former is larger and the net thickness of the latter is smaller. It's dark.

Therefore, in this case, a large load can be carried by the upper horizontal frame, and the same member used for the lower horizontal frame can be used as a connector for this horizontal frame.

FIG. 12 shows a connection similar to that shown in FIG. 10, except that only the shape of the connector is different.

As shown by reference numeral 11, the connector may have a U-shaped cross section.

Figure 13 shows the case where the front horizontal frame C and the mound pillar in the framework of Figure 2 are connected, and Figure 14 shows the case where the side horizontal frame C and the mound pillar are connected. The connection can be made using a connector 12 of the same shape (this connector is the same as the one shown with reference numeral 10 in FIGS. 9 and 10), but the connector 13 inserted into the inside of the mound pillar 2 is The dimensions must be different from those of the connector 12.

This is because the inner diameters of the shapes used for the second mound pillar are different.

Note that reference numerals 14 and 14 are screws for fastening similar to those described above.

FIG. 15 shows an embodiment in which the above-mentioned connector is standardized, and the overall shape is made up of a rectangular parallelepiped member with a square or rectangular cross section, and each end face of the rectangular parallelepiped member 15 has a dead-end screw. A hole or a penetrating screw hole 16 is bored in advance.

This connector made of a rectangular parallelepiped member can be used as is in each of the above-mentioned embodiments, and can also be applied to the molded material shown as Ill. 2 in FIG.

Note that the connectors shown in Figure 15 (b) are used by stacking two or four connectors of the unit shown in Figure 15A (by adhering them if necessary).

As described above, the connector used in the present invention can have a square or rectangular cross section that matches the inner diameter of the molded material, making it possible to standardize the connector itself.

However, in the present invention, it is not always necessary to use a standardized connector; for example, a U-shaped bracket 5, as shown by reference numeral 11 in FIG. 12, may be used as the connector.

As described in detail above, the present invention provides a shape material having a square or rectangular cross section (long side and short side having a specific ratio) whose outer diameter and inner diameter are each made into a specific shape, and which has an apparent appearance. By keeping the wall thickness constant, the outer surfaces of the shapes can be matched in harmony, and connections can be made with the same outer shape but different wall thicknesses. It has the advantage of being able to be joined using the same connecting material.

This is extremely advantageous when changing the wall thickness to increase buckling strength or bending strength.

In addition, even when the outside appearance is the same and the net thickness is changed depending on the strength, the same standardized connector can be used, so standardization of materials can be achieved.

In other words, in the present invention, the outer diameter dimensions of a plurality of mold materials used in combination with each other are determined based on one specified square common to all the plurality of mold materials, and the inner diameter dimensions are also determined based on the apparent thickness of the mold materials. Since the thickness is a value obtained by multiplying the length of the opposite sides adjacent to each other by a certain ratio, the dimensions of these multiple mold materials are all kept in a multiple relationship, and as a result, these mold materials can be used mutually. (no matter how they are combined), the consistency relationship is maintained.

Therefore, when these shapes are joined together, not only can they be tightly fastened, but there is no misalignment and compatibility is exhibited.

Furthermore, according to the present invention, it is possible to reduce the weight of the aluminum material, and therefore the product can be provided at a low cost, and it is possible to standardize not only the shape material itself but also the connectors etc. This will bring new industrial effects.
