Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a new joint for architectural structural members used in structures such as wooden houses or reinforced steel structures, and more specifically, it relates to a new joint for building structural members used in structures such as wooden houses or reinforced steel structures, and more specifically, This invention relates to metal joints that allow structural members to be assembled extremely easily at construction sites.

<Conventional technology> Conventionally, in the construction of buildings such as wooden houses, after constructing the foundation, in order to connect structural members such as wood, it is necessary to carve vertically and horizontally each member at their joints, Cuts, notches, etc. are made, and these are inserted to connect the two. However, such conventional construction methods require a high degree of skill and skill to join wood, etc., as described above, and have many problems, such as poor work efficiency, poor economic efficiency of components, and poor strength of joined parts. It has its drawbacks.

Therefore, as a result of many years of intensive research into the method of joining structural members such as those described above, the present applicant has found that the method is even simpler than the conventional simplest method, for example, the method of combining various steel plates and bolts/nuts. Moreover, in terms of strength, we have developed a joint for architectural components that is superior to the traditional Japanese wooden carving method.

Such a joint is disclosed in Japanese Unexamined Patent Publication No. 107626/1983.

That is, in this joint, a plate-like member extending outward from the surface of the joint main body in the shape of a cube or a rectangular parallelepiped in a plane substantially orthogonal to the surface is welded to the joint body, and the plate-like member includes: A hole is provided through which a fastener such as a bolt can be inserted.

A large number of types of such conventional joints for building members can be obtained by combining the joint main body and the plate-shaped members by changing their shapes, numbers, and directions.

Figure 10 shows an example, in which 1 is the joint body;
2 is a plate member.

<Problems to be Solved by the Invention> However, such conventional joints are manufactured by welding and fixing the plate member to the joint body. It takes a lot of time to assemble, and the ease of assembly is poor. Further, during this assembly, it is difficult to put it on a production line in a factory, etc., and mass productivity is poor.

Furthermore, unless the shape, number, and direction of the plate members are carefully controlled, it will be impossible to manufacture the required joint, and this control requires a great deal of effort. This is even more so since there are many types of joints.

In addition, in the construction of buildings, if the wrong joint is used by mistake when joining structural members such as wood, the troublesome replacement of the joint is required, which greatly reduces drawing efficiency. There was also a drawback.

Furthermore, when extending or renovating a building that uses conventional joints, the joints of structural members such as wood cannot be changed unless the joints used are replaced. It was a long time ago.

The present invention has been made in view of these conventional problems, and eliminates the structure in which plate members are welded and fixed to the joint body, and instead uses fasteners to allow attachment and detachment of at least some of the plate members. It is an object of the present invention to provide a joint for a building member that eliminates the above-mentioned conventional problems by having a structure that allows the direction to be changed.

Means for Solving the Problems> For this reason, the present invention provides a rectangular joint body, a plate-like member that can be freely attached and detached to each of the six faces of the joint body,
The plate-like member has a first plate part and at least one second plate part extending from the surface of the cough plate part in a plane substantially perpendicular to the surface, and has a wall part of the joint body and The first plate part has mounting holes for fasteners for fastening the two parts, and the positions of the mounting holes provided in at least the pair of opposing joint main body walls and the plate-like member connected to the walls are set at the first plate part. The first plate part is provided in a position such that it can be selectively coupled in two directions shifted by an angle of 90 degrees on the surface of the joint body, while the second plate part is provided with a structure for fastening the plate part and the building member. This is a joint for building components that is configured with mounting holes for fasteners.

<Function> With the above configuration, a large number of types can be obtained by changing the shape, number, and direction of the plate-like members and fastening them to the joint body, resulting in excellent assemblability. In addition, since the plate-like members can be attached and removed freely, the number and direction of the plate-like members can be easily changed, and it does not take much effort to manage the assembly. If a different joint is used by mistake when joining, there is no need to replace the entire joint, improving work efficiency.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 9.

In FIG. 1, a joint for building components (hereinafter referred to as joint) 3 has a core 4 as a rectangular joint body, and
Consisting of two types of joiners 5 and 6 as plate-like members that can be connected to six sides of the core 4, respectively, the core 4 and the joiner
5 and 6 are both made of metal, especially iron and steel.

The core 4 consists of a rectangular parallelepiped-shaped hollow body consisting of two square surfaces at the top and bottom and four rectangular surfaces at the sides.The method is to cut a prismatic steel pipe to a predetermined size and weld steel plates to the cut surfaces at both ends. It is formed by etc. The core 4 may be a solid body, but a hollow body is more advantageous in terms of handling and economy. Four mounting holes 8 for bolts 7 as fasteners for fastening the joiners 5 and 6 are provided in each of the six walls of the core 4. As shown in FIG. 2, nuts 9 are fixedly attached to the openings of the attachment holes 8 on the inner surface of the wall of the core 4 by welding.

The size of the core 4 is determined by the size of the structural members to be connected, for example, if the members are foundations, columns, etc.
When it is a structural member such as a beam, (5 to 15)
L5) x (5 to 20) cm is typical.

Further, the thickness of the plate constituting the core 4 is usually 2 to 101 m to obtain sufficient strength.

The joiner 5 is a vertical joiner that can be joined to the upper and lower walls of the core 4, and the joiner 6 is a horizontal joiner that can be joined to the side walls of the core 4.

The vertical joiner 5 and the horizontal joiner 6 each have a first plate part 5A, 6A and a surface of the first plate part 5A, 6A so as to extend outward perpendicularly to the surface in a plane substantially orthogonal to the surface. It has second plate parts 5B and 6B to be welded. The first plate part 5A of the vertical joiner 5 is formed to have the same area as the upper and lower surfaces of the core 4, and the mounting holes 10 for the bolts 7 are provided at positions that match the mounting holes 8 in the upper and lower walls of the core 4. It is provided. Further, the second plate portion 5B of the vertical joiner 5 is provided with a mounting hole 12 for a bolt (not shown) as a fastener for fastening the plate portion 5B and a building member. On the other hand, the first plate part 6A of the horizontal joiner 6 is formed to have the same area as the side surface of the core 4, and a mounting hole 13 for the bolt 7 is provided at a position that matches the mounting hole 8 in the side wall of the core 4. It is being Further, the second plate part 6B of the horizontal joiner 6 has a pole 1 as a fastener for fastening the plate part 6B and a construction member.
Four mounting holes 15 are provided. The first plate part 6A of the horizontal joiner 6 has a beam support plate 16 extending from the lower end of the plate part 6A in a plane substantially perpendicular to the surface of the plate part 6A and the surface of the second plate part 6B. They are welded and fixed to each lower end. Although the beam support plate 16 has a rectangular shape in the figure, it may have a triangular shape.

Here, the positions of the mounting holes provided in at least a pair of opposing core 4 wall portions and a plate-like member coupled to the wall portions are set so that the first plate portion is located at two locations 90 degrees apart from each other in the plane of the core 4. It is provided at such a position that it can be selectively coupled in the direction.

That is, the distance between the mounting holes 8 in the upper and lower walls of the core 4 is equal to the distance between the mounting holes 10 in the first plate portion 5 of the vertical joiner 5, and The upper and lower surfaces of the core 4 can be selectively coupled in two directions that are angularly shifted by 90 degrees.

Such joiners 5 and 6 may normally be formed from plate members having a thickness of 2 to 1Qms.

Several tens of types of such joints 3 can be obtained by selecting the number of vertical joiners 5 and horizontal joiners 6 used, selection of the mounting surface to the core 4, and selection of the mounting direction of the vertical joiner 5 on the core 4 surface. .

Here, typical examples of joints are shown in Figures 3 (A) to (G).
).

Next, how to use the joint described above will be explained.

First, in order to fasten structural members such as foundation members, columns, and beams to the joint 3, as shown in FIG. Align it with both sides of the plate part 6B. The bolt 1 is inserted into the mounting hole 15 of the second plate portion 6B and the bolt insertion hole 18 provided in the passenger plate member 17 so as to match the position of the mounting hole 15.
4 and the oak fitted to the tip of the bolt 14! - 19, the pair of riding plate members 17 are fixed to the second plate portion 6B. In this case, the ends of the pair of riding slope members 17 are received on the beam receiving plates 6. Incidentally, a concave surface pressure 20 into which the bolt 7 is inserted is formed on the butt surface of each of the pair of riding plate members 17 to the first plate portion 6B of the horizontal joiner 6, that is, on the butt end, by a round counterboring process. ing.

In this explanation, a pair of riding slope members 17 are combined to constitute a building member, but the construction is not limited to this. For example, as shown in FIG. 4, a single riding board member 21
It is also possible to use a groove 22 formed in advance so that the second plate part 6B can be inserted only into the connecting end of the groove. However, considering the complexity of groove cutting and workability due to weight, it is more preferable to use a pair of structural members. or,
Architectural members are not limited to wood, but may also be made of other materials, such as steel frames. When taking the illustrated Santoy and Sochi structure,
Structural members such as foundations, columns, and beams are all formed by combining two materials, but unless there are special cases, there is no need to separately bolt or secure the structural members located between the joints with adhesive. Compared to ordinary foundations and pillars, it can be said that the strength of plywood is greater than that of ordinary foundations and pillars.

FIG. 5 is a plan view of the foundation of a building using joints. Seven types of joints were used to connect the structural members in this base part, and these are joints JTI to JT7 shown previously in FIGS. 3(A) to 3(G).

FIG. 6 is a sectional view of the front of a building using joints.

In the figure, the concrete foundation 23 is configured as a continuous foundation. A base 24 is placed on top of the concrete foundation 23 and fixed by anchor bolts 25 buried in the concrete foundation 23 in advance.

A base member 26 is placed on the top of the base 24, and these base members 26 are connected to each other at JT5°JT6 as shown in FIG.
etc. are connected by joint 3A. The joint 3A is fixed to the base 24 by a column base metal fitting 27 as shown in FIG. As shown in the figure, the column base hardware 27 is formed into a substantially T-shape, including a plate portion 27a fixed to the base 24 with bolts and a plate portion 27b fixed with bolts to the side wall of the core 4 of the joint 3A. Bolt insertion holes 28c are formed in each of the plate portions 27a and 27b. In this case, the plate portion 27b of the column base hardware 27 is formed to have the same area as the side surface of the core 4, and the bolt insertion hole 28c is provided at a position that matches the mounting hole 8 in the side wall portion of the core 4.

On the other hand, the company members 29 are each connected to joints 3A that connect the foundation members 26, and the upper and lower company members 29 are connected to each other by a joint 3B.

The riding member 30 is connected to a joint 1-3B that connects the upper and lower company members 29 and a joint 3C that connects to the upper end of the upper side column member 29. In addition, in FIG. 6, 31 is a joist, 32 is a joist holder, 33 is structural plywood, and 34 is oak wood.

Once the construction of the foundations as shown above has been completed, joists 31 etc. are placed between each foundation as necessary, and structural plywood 33 which will become the floorboards is placed over the entire surface by nailing etc. Target. In this state, the surface (platform) on which the structural plywood 33 that will become the floorboard is stretched becomes a workbench for the next work, and then the vertical joiner 5 of the joint 3A is used to erect columns, and beams, rafters, etc. are assembled. This point is very different and advantageous from conventional construction methods for wooden houses.

In other words, in the conventional construction method, the entire structural members such as foundations, columns, beams, rafters, and roofing boards were joined together and then the floorboards, etc. Since it is possible to combine the parts with each other, the work is very easy to perform, the construction period can be significantly shortened, and it is extremely economical.

According to the joint described above, the connection of structural members can be completed by simply tightening bolts. Furthermore, the floor area and height of the building can be changed freely using standard products with a small amount of scraping, and even after the construction is completed, if you plan on expanding or remodeling in advance and using the joints for that purpose, it is extremely easy to expand or remodel. Therefore, just like combining block toys of various shapes, various types of houses can be constructed one after another according to the demands of customers using decimal standard products. Furthermore, by standardizing joints and structural members to which they are applied, mass production in factories becomes possible, and even people without special skills can construct new buildings, expand and renovate them. Furthermore, the connection of structural members using joints is extremely strong, and is superior to conventionally known simple steel plates, bolts, etc.
It is overwhelmingly stronger than the method using nuts.

This is all due to the special structure of the joint 3, ie, the connecting structure of the core 4, the vertical joiner 5, and the horizontal joiner 6.

In particular, the joint 3 having such a configuration is manufactured by bolting the vertical joiner 5 and the horizontal joiner 6 to the core 4, so that it is easy to assemble the vertical joiner 5 and the horizontal joiner 6 with the core 4. It requires less effort, is easy to assemble, and is superior in mass production. Furthermore, even if the shape, number, and direction of the vertical joiner 5 and horizontal joiner 6 relative to the core 4 are incorrect, they can be easily changed, so there is no need for strict management of core errors, and this management requires a lot of effort. There is no such thing as hanging.

Also, in the construction of a building, if you accidentally use the wrong joint when joining structural members such as wood, you can replace the vertical joiner 5 and horizontal joiner 6 to find the correct joint. You can easily change the joint to the one you want, and there is no need to replace the joint, which is the troublesome conventional method.
Work efficiency can be improved.

Furthermore, when carrying out an extension or renovation, the connection of structural members can be changed by replacing the vertical joiner 5 and horizontal joiner 6, without having to replace the used joints.
This will allow for more freedom in additions and renovations.

In the above embodiments, the vertical joiner 5 and the horizontal joiner 6 each have one second plate portion 5B, 6B, but as shown in FIG. The plate portions 35B and 36[3 may be provided with two plates.

In this case, the second plate parts 35B and 36B are connected to the first plate part 35.
A and 36A are fixed to both side edges by welding and are opposed to each other at a predetermined interval. Further, the second plate portion 35B of the vertical joiner 35 is provided with a mounting hole 12 for a bolt (not shown) as a fastener for fastening the plate portion 50B and a building member, as in the previous embodiment. It is being On the other hand, horizontal joiner 36
Similarly to the previous embodiment, the second plate portion 36B is provided with a mounting hole 15 for a fastener 14 for fastening the cough plate portion 36B and a building member. In this embodiment as well, the distance between the mounting holes 8 in the upper and lower walls of the core 4 is equal to the distance between the mounting holes IO in the first plate portion 35A of the vertical joiner 35. 35A to core 4
It is possible to selectively connect in two directions shifted by an angle of 90 degrees on the upper and lower surfaces. Such a joint 37 includes a vertical joiner 35 and a horizontal joiner 36.
As in the previous embodiment, dozens of types can be obtained by selecting the number of joints used, the mounting surface to the core 4, and the mounting direction of the vertical joiner 35 on the core 4 surface.

Here, in the previous embodiment, in order to fasten structural members such as foundation members, columns, beams, etc. to the joint 3, the ends of the structural members are connected to the second joint of the vertical joiner 5 and the horizontal joiner 6, respectively. In this embodiment, for example, as shown in FIG. The structural member 38 is inserted between the two second plate parts 36B, and the structural member 38 is sandwiched between the two second plate parts 36B and fixed.

Incidentally, the two second plate parts 35B, 36B and one second plate part 5B, 6B of the previous embodiment are mixed to form the core 4.
It may be used by attaching it to.

<Effects of the Invention> As explained above, according to the joint for building components of the present invention, the rectangular joint body can be freely attached and detached using fasteners on each of the six faces of the joint body. A plate member to be obtained;
In addition to the structure, the installation direction of at least some of the plate members can be changed, which shortens the construction period, standardizes the parts, reduces costs, increases strength, and improves workability, and does not require skilled craftsmen. Not only does it have the advantages of freedom of design, freedom of extension/renovation, and factory production, but since the plate member is manufactured by tightening fasteners to the joint body, it is easy to assemble the plate member and the joint body. does not require skilled craftsmen, requires less labor for assembly, is easy to assemble, and is better suited for mass production. Furthermore, even if the shape, number, and direction of the plate members relative to the joint body are incorrect, they can be easily changed, so there is no need for strict management of core errors, and this management does not require a great deal of effort. do not have.

Additionally, in the construction of a building, even if you mistakenly use the wrong joint when joining structural members such as wood, you can easily change to the required joint by replacing the plate-shaped member, etc. This eliminates the need for the troublesome replacement of joints as in the past, improving work efficiency.

Furthermore, when carrying out extensions or renovations, the connection of structural members can be changed by replacing plate-shaped members or the like without having to replace the used joints as they are, making it possible to carry out extensions and renovations more freely.
