Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pillar-shaped structural material for construction such as a beam, a purlin, a girder, and a kamoi which is mainly used horizontally in a building.

[0002]

2. Description of the Related Art In a wooden building, horizontal materials such as beams and girders have the role of supporting the weight of roof tiles, floors, and ceiling floors in the middle of columns. It is a common experience of ourselves that when bending occurs in a material, the load is transmitted to the railing and the Kamoi, and the sliding doors and the like installed below it do not open and close during long-term use.

In order to solve this difficulty, a thick wood material may be used to increase the load pressure resistance, but this naturally increases the material volume and occupies a large amount of wasted space. As the material volume increases, its own weight also increases, which adds to the load of the entire building frame.

In order to compensate for this, it is possible to use a metal core material having high rigidity and toughness, but it is difficult to incorporate the metal core material into wood, and it was possible to include it. As a result, it is difficult for the wood and the metal core material to exhibit the load resistance in a discrete manner, and for example, if the load is concentrated on the metal core material, the wood is not required to exert the load resistance against this. Even so, it is necessary to increase the material volume of the metal core material, and as a result, the weight becomes greater than the weight of wood and added. Further, if the load is concentrated on the timber, it will lead to bending, cracking or breakage of the timber.

[0005]

By the way, although wood has a natural scent, warmth, and easy workability peculiar to wood, it has the drawback of lacking load resistance as described above. As described above, since the load resistance of wood is poor, there is a limit to increasing the size of a building. Also, depletion of raw wood resources is being called for, and there is a possibility that the supply of timber will approach the limit in the future. Moreover, even if it is not exhausted, it is difficult to obtain a long wood due to the nature of growing wood. An object of the present invention is to obtain a horizontal member having a required length by simply integrally connecting these pieces of wood even with such relatively short pieces of wood. On the other hand, metal has rigidity and toughness, is cheaper than wood at this time, and is excellent in mass supply, but it is inferior in terminal processability during construction and lacks natural scent and warmth. is there.

[0006] Therefore, it is an object of the present invention to provide a structural material for construction which complements the drawbacks of wood and metal with each other and makes the best use of each other's advantages.

[0007]

In order to solve the above-mentioned problems, the present invention provides the metal strip 1 which is the core material in claim 1 by referring to the reference numerals shown in the embodiments. Round holes 2 are opened at appropriate intervals in the longitudinal direction, and metal short pipes 3 are provided in each round hole 2.
The metal strip 1 and the pair of wooden planks 4 and 4 properly fitted.
And the metal short pipes 3 are sandwiched and opposed to each other, and the recesses 5 (5a, 5) in which the metal strips 1 and the metal short pipes 3 are properly fitted to each other on opposite surfaces.
b) is provided, the two wooden planks 4 and 4 are superposed by sandwiching the metal strip 1 and the metal short pipe 3, and the two wooden planks 4 and 4 are fixed to each other. .

According to the second aspect of the present invention, the circular holes 2 are formed in the metal strip 1 which is the core material at appropriate intervals in the longitudinal direction.
The metal short pipe 3 is fitted properly to the metal short pipe 3 and a pair of wood attachment plates 8 and 8 having round holes 7 into which both ends of the metal short pipe 3 are fitted properly are provided on both sides of the metal strip 1. On the other hand, the pair of wooden planks 4 and 4 are connected to the metal strip 1, the metal short pipe 3 and the wooden attachment plates 8 and 8.
The wooden planks 4 and 4 are provided with a recess 9 on the opposing surfaces of the wooden planks 4 and 4 so that the wooden attachment plates can be fitted properly. 3 and the wooden added plates 8 and 8 are sandwiched between them to be polymerized, and both wooden thick plates 4 and 4 are fixed to each other.

[0009]

According to the first aspect of the present invention, since the metal strip 1 and the metal short pipe 3 properly fitted thereto are covered with the wooden planks 4 and 4, the wooden plank 4 is apparently used. Only the structure is exposed, so you can take advantage of the unique appearance of the wooden structure.

Further, a metal short pipe 3 is appropriately fitted to the metal strip plate 1 so as to be orthogonal to the metal strip plate 1, and the wooden short plates 4 and 4 on both sides thereof are together with the metal strip plate 1 in the thickness direction. As a result, the contact area between the metal strip 1 and the metal short tube 3 integrated with the metal strip 1 and the wooden plank 4 becomes large,
The load from the wooden plank 4 which directly receives the load of the building frame is distributed and received along with the metal strip 1 over the entire outer peripheral surface of the metal short pipe 3, so that the wooden plank 4 or the metal strip 1 receives the load. The metal strip 1 and the metal short tube 3 are not loaded by the local load.
In addition, the wooden planks 4 and 4 are separated and integrated to exert load resistance. In particular, due to the action of the metal short tube 3 integrally provided on the metal strip 1 in the thickness direction, the metal strip 4 has sufficient durability against a load applied to the wooden plank 4 from above and below.

Further, these loads are received in a distributed manner in the longitudinal direction by a number of metal short tubes 3 integrally provided on the metal strip 1 at appropriate intervals in the longitudinal direction, and the metal strip 1 or the wooden planks 4 are received. Since the load is not locally applied to a part of the longitudinal direction of the building, it is possible to prevent the bending of the building body due to the load from the vertical direction.

The metal strip 1 has round holes 2 at appropriate intervals in the longitudinal direction, and the metal short pipes 3 are properly fitted in these round holes 2, and both ends of the metal short pipe 3 are properly fitted. Since these are integrally polymerized in the state where the hollow 5 is provided in the wooden plank 4, a metal short tube cavity is formed in the longitudinal direction inside the pair of mutually overlapping wooden planks 4, 4. Therefore, it can be formed to be sufficiently lightweight in terms of weight. Further, in the related art, there is a possibility that the beam may be perforated for drilling for piping or electric wiring, but the strength may be deteriorated. However, in the present invention, the use of the metal short pipe 3 can avoid the fear.

Furthermore, a hollow portion is formed in the longitudinal direction of the pair of wooden planks 4 and 4 to be polymerized and fixed to each other by the metal short pipe 3, so that a simple terminal processing is performed, for example, piping and wiring. The passage can be easily formed.

In terms of overall volume, since the pair of wooden planks 4 and 4 that are polymerized and fixed to each other occupy a larger volume than the metal strip 1 and the metal short pipe 3, the workability peculiar to wood is obtained. Can be held, and terminal processing such as nailing, drilling or groove processing can be easily performed.

Furthermore, in the case where a plurality of building structural materials formed as described above are joined together, one wooden plank 4 and the end of the other wooden plank 4 which is abutted against this in the longitudinal direction. Attach a suitable connecting member over the outer surface,
By fixing the connecting member to the metal strip 1 inside the wooden plank 4 with nails or the like, it is possible to manufacture a long construction structural material without lowering the strength of the connection portion.

According to a second aspect, a pair of wooden splint plates are provided on both sides of the metal short pipe 3 integrally provided on the metal strip 1 with round holes 7 into which the metal short pipe 3 is fitted properly. It is advantageous for mass production that a unit with 8 and 8 attached can be manufactured in advance, and the wooden addition plates 8 and 8 are suitable for the pair of wooden thick plates 4 and 4 which oppose this. Since it suffices to provide the recess 9 to be fitted, the number of processing steps is small, and the manufacturing can be performed relatively inexpensively.

[0017]

FIG. 1 shows the appearance of an embodiment of the present invention. A metal strip 1 made of non-ferrous metal or steel is sandwiched between the overlapping surfaces of a pair of wooden planks 4 and 4 in the entire longitudinal direction. Then, the superposed surfaces 6 and 6 of the two wooden planks 4 and 4 are fixed by an adhesive or the like. Moreover, both may be fixed by a bolt nut. Even if they are fixed by bolts and nuts, they are not conspicuous because they are both ends of the wooden plank 4.

FIG. 2 is an exploded perspective view of a pair of wooden thick plates 4 and 4, a metal strip 1 and a metal short pipe 3 which is fitted appropriately thereto, and the metal strip 1 is suitable for its longitudinal direction. Round holes 2 are provided at intervals, and a short metal tube 3 made of a non-ferrous metal or a steel material having an outer diameter substantially equal to the inner diameter of the round hole 2 is pressure-fitted properly as shown by an arrow in the drawing. Is manufactured as a unit in advance. On the other hand, a recess 5 in which the metal strip 1 and the metal short pipe 3 are embedded is formed on the opposing surfaces of the pair of wooden planks 4 and 4. Specifically, half of the thickness of the metal strip 1 is embedded in each of the wooden planks 4 so that the metal strip 1 is embedded therein.
A recess 5a having a depth substantially equal to that of the metal strip 1 is formed at the bottom of the recess 5a in the longitudinal direction thereof.
And the metal short pipe 3 so that it matches the position of the round hole 2 opened in
A round-hole-shaped depression 5b having an inner diameter substantially equal to the outer diameter of is formed. In addition, the dimensions of the metal strip 1 and the metal short pipe 3 which are core materials,
By changing the material, the weight and strength can be changed according to the use. Further, although the metal strip 1 is provided at the center of the pair of wooden planks 4 and 4, it is also possible to form the metal strip 1 in the vertical width of the wooden planks 4 and 4. In this case, the strength is further increased, and it can be used, for example, as a beam material in a portion that cannot be seen from the outside.

The metal strip 1 has a metal short tube 3 which is orthogonal to the metal strip 1.
One end of the wooden plank 4 is attached to the recess 5a of the wooden plank 4 so as to be pressure-fitted into the recess 5b of the round plank of the one wooden plank 4, and then the round of the other wooden plank 4 is fitted. Hole-shaped depression 5b
Similarly, the metal strip 1 is attached to the recess 5a of the wooden plank 4 so that the other end of the metal short pipe 3 is pressure fitted.
At this time, an adhesive is applied in advance to the overlapping surfaces 6 and 6 of the two wooden planks 4 and 4, and the two planks 4 and 4 are fixed to each other by polymerizing the two. Although not shown, both ends of both wooden planks 4 and 4 may be fixed by bolts and nuts as described above.

As a result, the structural material for construction according to the present invention is manufactured. As shown in FIG.
With the ends of the metal strip 1 slightly exposed at both ends of
Alternatively, although not shown, only the bolts and nuts are exposed, and most of them are covered with the wooden plank 4 and have an appearance as a wooden structural material.

As shown by the arrow in FIG. 3, even if the load of the building frame is applied to the wooden plank 4, the load is dispersed not only on the metal strip 1 but also on the entire outer peripheral surface of the metal short pipe 3. As a result, a strong load resistance can be exerted by the synergistic action of these members. Moreover, since the metal short pipe 3 is provided orthogonally to the metal strip plate 1, it has sufficient durability against a load acting on the wooden thick plate 4 in the twisting direction.

Further, since the metal short pipe 3 itself has a load carrying capacity which is even in all directions as compared with a metal material on a flat plate, it has sufficient durability not only in the longitudinal direction but also in the lateral direction. Have.

The metal strip 1 and the wooden plank 4 can be formed to be sufficiently lightweight as a whole because a cavity is formed inside when the metal strips 3 are superposed by a large number of metal short pipes 3. The strength deterioration due to the formation of the cavity is reinforced by the metal short pipe 3, and the strength deterioration is not seen as a whole.

Moreover, a large number of the metal short pipes 3 are provided on the metal strip 1 at appropriate intervals in the longitudinal direction, so that FIG.
As shown by the arrow, the load received by the wooden planks 4 and 4 is dispersed and supported by the large number of short metal tubes 3 arranged in the longitudinal direction through the metal strip 1. It does not locally load the parts of the thick plates 4 and 4 in the longitudinal direction, and has sufficient load resistance even when the load of the building frame is received. It does not bend even when used for a long time, and the result of the experiment shows that the metal strip 1 having a thickness of 1.6 mm
The strength of about 5 times that of the conventional timber beam material was recognized by using. Of course, if the metal strip 1 is thickened, it is possible to expect ten times or more strength by the synergistic action with the wooden planks 4 and 4. Furthermore, since it is wooden in appearance, it is possible to maintain the unique feel of wood.

FIGS. 5 to 7 show another embodiment of the present invention, in which the wooden strips 8, 8 attached to both sides of the metal strip 1 are provided on both sides of the metal strip 1 concentrically. Round hole 2,7
Are formed at appropriate intervals in the longitudinal direction, and the metal short pipes 3 are pressure-fitted over the round holes 2 and 7 of both to make them as a unit in advance. Is a recess 9 having a depth substantially corresponding to one half of the total thickness of the metal strip 1 and the wooden attachment plate 8 so that the metal strip 1 and the wooden attachment plate 8 fit properly. The above-mentioned unit consisting of the metal strip 1, the metal short pipe 3 and the wooden attachment plate 8 is installed in the recesses 9 and 9 of the wooden planks 4 and 4, and at this time, An adhesive material is applied to the overlapping surfaces 6 and 6 of each other in advance, and the two wooden planks 4 and 4 are fixed to each other by polymerizing the both. Of course, both may be fixed to each other by bolts and nuts as described above.

As a result, the structural material for construction according to the present invention is manufactured. As shown in FIG.
Also, the end portions of the metal strip 1 are only slightly exposed at both ends of the wooden attachment plates 8 and 8, and most of them are covered with the wooden planks 4 and have an appearance as a wooden structural material.

According to this embodiment, it is possible to mass-produce the above-mentioned unit consisting of the metal strip 1, the metal short pipes 3 and the wooden attachment plate 8 in advance, and the wooden plank 4 has a simple shape. This is advantageous in mass production because it is only necessary to form the recess 9 of

Also in this embodiment, as in the previous embodiment, even if the load of the building frame is applied to the wooden plank 4, as shown by the arrow in FIG. Not only that, the metal short pipe 3 is dispersed and received on the entire outer peripheral surface of the metal short pipe 3, and a strong load resistance can be exhibited by the synergistic action of these members. In addition, the same effects as those of the above-mentioned embodiment are exhibited.

FIG. 8 shows an example of the usage state of the present invention. When the building structural material formed as described above is replenished in the longitudinal direction, the outer circumferences of the ends of the wooden planks 4 and 4 are shown. The connecting members 10, 10 may be attached to the surface and fixed by the through bolt 11 and the nut 12 penetrating the metal strip plate 1. Furthermore,
Alternatively, another connecting member 13, 13 may be attached and fixed to the wooden planks 4, 4 with a wooden screw 14. In this way, since it is possible to easily and firmly add a structural material for construction, for example, a relatively short structural material for construction is manufactured, and this can be easily added to a long length in accordance with site work. It is convenient for transportation and storage.

[0030]

[Effect] According to claim 1 of the present invention, first of all, most of the wooden planks are exposed, and the merit in appearance peculiar to wooden structural materials, that is, the natural scent and warmth of wood. Can be utilized.

Further, according to the first aspect, the wooden planks directly receiving the load of the building frame are supported together with the metal strips on the entire outer peripheral surface of the metal short pipe. There is no local load on wooden planks or metal strips,
The metal strip, the metal short pipe, and the wooden plank will be separated and integrated to exert the load resistance. In particular, it will exhibit sufficient durability against the load from the vertical direction on the wooden plank. Therefore, it can be effectively used as a structural material for a main frame such as a beam material.

Further, these loads are received in a distributed manner in the longitudinal direction by a large number of metal short pipes integrally provided on the metal strip at appropriate intervals in the longitudinal direction, and are received in the longitudinal direction of the metal strip or the wooden plank. Since the load is not locally received on a part, it is possible to prevent the occurrence of bending of the building body due to the load from the vertical direction. From this point of view, it is effective as a structural material for beams.

According to the first aspect of the present invention, since a large hollow portion is formed in the longitudinal direction inside the pair of wooden planks which are overlapped with each other, the wooden planks have a sufficient load-bearing capacity, but are not heavy. Moreover, it can be formed to be sufficiently lightweight, and the ratio added to the overall load of the building can be reduced. Moreover, although the hollow portion is formed, the metal short pipe is inserted into the hollow portion, so that the strength deterioration due to the formation of the hollow portion is prevented by the action of the metal short pipe, and the horizontal strength is high as a whole. The material can be formed.

Furthermore, since a cavity is formed in the longitudinal direction of the pair of wooden planks to be polymerized and fixed to each other by the metal short pipe 3, a simple terminal processing can be performed to form a passage for piping or wiring. It can be easily formed, and the on-site processing work in construction work is extremely easy and practical.

In terms of the overall volume, the wooden plank occupies a larger volume than the metal strip plate or the metal short pipe, so that the workability peculiar to wood can be maintained, and nailing and drilling can be performed. Alternatively, terminal processing such as groove processing can be easily performed, and this is also practical.

Furthermore, when a plurality of building structural materials formed as described above are joined together, one wooden plank and the outer side surface of the end of the other wooden plank that is abutted on this wooden plank in the longitudinal direction. Since a suitable connecting member is attached over the entire length and the connecting member is fixed to the metal strip inside the wooden plank with nails or the like, the strength of the connecting portion is not lowered, so that the length not exceeding the commercially available rating is exceeded. It is possible to easily fabricate a structural material for construction. Furthermore, a relatively short building structural material can be manufactured in advance, and this can be added in a long length according to the site work, which is convenient for transportation and storage. Furthermore, it is possible to easily cope with the depletion of wood in the current growth of wood.

According to the present invention, although there is a limit to the size increase of a building depending on the timber frame, it is possible to increase the size to the same extent as that of a steel frame structure. It is possible to contribute to breaking down the increase in size.

Further, since it is possible to use a small amount of wood, it is possible to contribute to saving a large amount of raw wood resources.

Furthermore, in a building, the height from the underfloor to the ceiling depends on the thickness of the beam, but in the present invention, the volume thereof can be greatly reduced, so that useless space can be eliminated. This can be done by reducing the outer wall area of the building,
This will lead to a reduction in the number of stairs in multi-story buildings, and will greatly contribute to a significant reduction in total construction cost.

According to a second aspect of the present invention, a metal strip plate, wooden addition plates attached to both sides of the metal strip plate, and a metal short pipe which is pressure-fitted properly between the metal strip plate are unit-produced in advance and the wooden Since it is only necessary to form the dent having a simple shape in the thick plate, the number of processing steps is small, and mass production can be performed at a relatively low cost.
