Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fitting for joining wooden members suitable for, for example, joining a wooden pillar to an ascending beam, joining beams, and the like, and a joining structure of wooden members joined by the fitting.

[0002]

2. Description of the Related Art In recent years, in wooden construction, wooden members have been developed for the purpose of shortening the construction period, reducing labor costs, improving strength, improving durability, simplifying processing, and performing construction with high precision without relying on skilled personnel. Joining fittings are being used.

Conventionally, as this kind of fittings for joining wooden members, there are many joining fittings for joining portions such as columns and beams, or columns and bases, but there are few joining fittings for joining columns and climbing beams. The advantages of climbing beams are that they use less wood than conventional ones, so they are advantageous in terms of cost and construction period, can be used widely in the attic, and have high strength.

Conventionally, as this kind of fittings for joining wooden members, those disclosed in Japanese Unexamined Utility Model Publication No. 6-51306 (hereinafter referred to as prior art 1) and those disclosed in Japanese Patent No. 25009036 (hereinafter referred to as prior art 2). ). These are of the type that is fixed to a column and climbs up on a support plate for receiving the beam. Further, Japanese Unexamined Patent Application Publication No. 8-23991
A U-shaped plate is fixed to a pillar as shown in JP-A No. 1 (hereinafter, referred to as prior art 3) and as shown in JP-A-9-100580 (hereinafter, referred to as prior art 4). There is a method of dropping a beam provided with a slit on a character-shaped plate.

In the above prior art 1, since the climbing beam is supported not only by the drift pins but also by the iron plate, the strength is high.
Even in the event of a catastrophic failure that results in large deformations, it is more likely that the climbing beam will be supported, so that safety is high.

[0006] As another conventional joining metal fitting, there is one disclosed in Japanese Utility Model Laid-Open Publication No. 6-20608 (hereinafter referred to as a conventional technique 5).
The method of placing a climbing beam on a pillar and fixing it with a reinforcing bar and an adhesive, or a method of inserting an iron plate inside a pillar and a beam and fixing it with a pin, or JP Showa 57-
A method of inserting an iron plate into columns and beams and fixing it with bolts, as disclosed in Japanese Patent No. 40042 (hereinafter referred to as Conventional Technique 6), and a method disclosed in Japanese Utility Model Registration No. 3014220 (hereinafter referred to as conventional). A method of pulling a beam to a column and fixing the same to a column as described in "Technology 7", and a portion to be fixed to a column and a portion to be fixed to a climbing beam as disclosed in Japanese Patent No. 250936 (hereinafter referred to as "Prior Art 8"). There is a method in which the angle can be freely adjusted by connecting with a hinge.

[0007]

However, such conventional fittings for joining wooden members have the following problems.

In the prior arts 1 and 2, since the iron plate for receiving the beam and the like is fixed to the metal fitting body, the angle of the beam can correspond only to the angle of the iron plate. For this reason, the degree of freedom in designing a climbing beam or the like is restricted. Therefore, it is necessary to prepare various metal fittings corresponding to the angles of the climbing beams or the like in advance, which causes an increase in die cost and inventory. Alternatively, if it is manufactured for a custom-made product, it is possible to cope with a beam having an arbitrary angle in various ways. However, there is a problem that the cost is increased due to the production of one product and the delivery time is delayed.

Furthermore, in the case of the prior arts 3 and 4, as shown in FIG. 5, the angle of the climbing beam can be dealt with as long as the angle is within a certain range. Can not. In addition, this joint requires two types of metal fittings, one for the up beam and the other for the down beam, which increases the cost of the mold and the stock.

In general, in wooden constructions, it is important to protrude the eaves by projecting the lower end of the climbing beam forward beyond the pillar from the viewpoint of energy saving due to solar shading in summer or the like. There is a problem that the upper pillar wins and the eaves cannot be taken out.

In the case of the prior arts 5 to 7, the device is devised so that the eaves can be protruded.
Since it is necessary to inject an adhesive after inserting the reinforcing bar into the pillar material or the joint material, there is a lot of time and labor required for construction on site, and there is a problem of safety due to work at a high place. Moreover, these works are not suitable for ordinary houses, as a large site is required to perform these operations on the ground.

[0012] Regarding the prior art 6, the prior art 5
This method inserts an iron plate into a pillar or beam in the same way as that described above, but requires additional work due to the use of adhesives, and has the same problems as cost, safety, and site. There is a problem that a material with a large cross-sectional area is required in order to hit many pins or nails in order to maintain the quality, and it cannot be said that it is suitable for ordinary houses. It is conceivable to attach metal fittings to columns and beams at the factory and transport them in order to save time and labor at construction sites.However, since these metal fittings protrude laterally from the column and beam mounting parts, these columns and beams can be used. Since it is difficult to arrange them in close contact with each other in the lateral direction, their transportation efficiency is poor.

Further, in the prior art 6, since there is no temporary fixing means for temporarily fixing the climbing beam to the column, when the gradient of the climbing beam is large, the climbing beam is likely to slide off the column, which is dangerous. Also, since there is only a fastening bolt for mounting, the positioning means for aligning the joint fitting to the mounting position of the column and the beam, the pilot hole and the play for inserting this bolt, the column and the beam,
There is a problem in that the mounting position of the mounting bracket is shifted, and the efficiency of the mounting operation of the mounting bracket is reduced.

Further, after the column and the beam are joined, only the bolt receives the load, so that the load is concentrated on the bolt,
The strength is weak, and the deformation due to the change with time tends to increase.

In the case of the prior art 7, a force for attracting diagonal members such as columns and climbing beams acts to increase the joining force between the two members. However, the number of parts is large, and therefore, the mounting process of the metal fitting is required. The number is large, and the man-hours required to process the diagonal material itself such as climbing beams are large, and these factors increase costs.

In the case of the prior art 8, the joining angle between the column and the diagonal member such as the climbing beam can be adjusted to an arbitrary angle, but the hinge structure increases the manufacturing cost and increases the weight of the fitting itself. There is.

As described above, the vertical inclination angle of the climbing beam can be appropriately adjusted, but the horizontal angle of the climbing beam, that is,
The angle around the center axis of the column is limited to almost a right angle,
There is a problem that the outer shape of the building is limited to a square.

Accordingly, the present invention has been made in view of such circumstances, and an object of the present invention is to provide a column or the like corresponding to various vertical inclination angles and horizontal angles of diagonal members such as climbing beams. It is an object of the present invention to provide a low-cost wooden member joining fitting which can be easily joined to a wooden member and a joining structure of a wooden member joined by the fitting.

Therefore, the upper half of the joint 1 is fixed to the climbing beam joining end 3a by driving the drift pins 10 into the through holes 3f of the joining end 3a of the climbing beam 3 respectively.

Thus, the joining ends 2a, 3a of the pillar 2 and the climbing beam 3 are firmly fixed by the joining fitting 1 in a state where the eaves tip 3x projects beyond the pillar 2.

Further, the inclination angle of the climbing beam 3 is restricted only by the inclination angle of the abutting surfaces of the joining ends 3a and 2a of the climbing beam 3 and the column 2. The inclination angle of the climbing beam 3 is determined by the joint fitting 1. Since there is no restriction, it is possible to cope with various inclination angles (vertical inclination angles) of the climbing beam 3 with this one type of joint fitting 1.

Accordingly, it is not necessary to manufacture and store various joining fittings 1 corresponding to various inclination angles of the climbing beam 3, so that cost can be reduced, and
It is possible to improve the workability of the work for attaching and joining the joining fitting 1 to the joining ends 2a and 3a of the pillar 2 and the climbing beam 3.

Further, as shown in FIG. 5, the joining end 3a of the climbing beam 3 is dropped onto the joining fitting 1 fixed to the column 2,
The climbing beam 3 can be temporarily fixed by the joining metal fitting 1 in a state in which the upper half portion of the joining metal fitting 1 is fitted into the fitting groove 3b, so that the climbing beam 3 is prevented from sliding down on the column 2. And safety at the construction site can be improved. At the time of the temporary fixing, a pair of guide pins 5a,
Since 5b is fitted in each of the fitting concave portions 2 and 3d, it is possible to prevent the joining surface of the climbing beam 3 from being shifted from the joining surface of the column 2 due to its inclination. In addition, since the pair of guide pins 5a and 5b are on or near the joint surface between the climbing beam 3 and the column 2, the load on the guide pins 5a and 5b can be reduced. For this purpose, the guide pin 5
a, 5b can be reduced in size.

Then, as shown in FIG. 4, in the step of fixing the joint 1 to the fitting groove 2b of the column 2, the upper half of the joint 1 in the figure projects axially from the joint end 2a of the column 2. ,
Since it does not protrude in the lateral direction (perpendicular to the axis), for example, in a factory or the like, when the joining fitting 1 is fixed to the column 2 in advance to form a wooden member joining structure, and a plurality of the joining members are transported to the construction site, Even if the plurality of wooden member joint structures are arranged at a high density in the lateral direction, it is possible to transport the adjacent joint members 1 without causing interference. Therefore, it is possible to improve both the efficiency and ease of transportation of the wooden member joining structure.

Furthermore, since the width direction of the joining metal fitting 1 whose cross section modulus is larger than the thickness direction substantially coincides with the longitudinal direction of the climbing beam 3, the strength of the joining metal fitting 1 itself or the height of the column 2 can be improved. The joint strength of the beam 3 can be enhanced together.

As described above, the joining fitting 1 can join the climbing beam 3 having various vertical inclination angles to the column 2 in a state where the eaves tip 3x is formed, and the inclination angle of the climbing beam 3 is, for example, as shown in FIG. Any kind of gradient from the three-dimensional gradient shown in FIG. 7 to the eight-dimensional gradient shown in FIG. 8 or from now on to the ten-dimensional gradient shown in FIG. 7 to 9, the broken line indicates the climbing beam 3.

[0134]

As described above, according to the present invention, when inserting both ends of the wooden member joining fitting into each fitting portion of each joining portion such as a pillar and a beam of the wooden member to be joined. , The insertion position is positioned by the first positioning means, and the insertion direction is guided. For this reason, the positioning of the insertion of the wooden member joining fitting into each fitting portion can be performed with high accuracy and easily. And
A wooden member joint fitting is inserted into both fitting portions of both joint ends of the column and the beam so as to straddle between these joint ends, and the fixture is fixed to the column and the beam, respectively. These pillars and beams are strongly joined via a joining member for wooden members.

Further, the wooden member joint fitting is merely inserted and fixed in each fitting portion of the joint end portion of, for example, a column and a beam, and is used to restrict the joint angle of the column and the beam. Since there is no member such as a part, it is possible to cope with various vertical inclination angles of the beam and the like and various horizontal angles of the beam by using one kind of wooden member joining fitting.

Therefore, it is not necessary to manufacture and store various metal member fittings in advance for various angles of inclination of the beam and the like and for each horizontal angle along the center axis of the column. The workability of the joining work can be improved, and the cost can be reduced.

Further, since the wooden member joining fitting has the first positioning means, for example, one end of this joining fitting is inserted into the fitting portion at the joining end of the upright pillar,
With the other end of the metal fitting protruding upward from the joint end of the column, the fitting portion of, for example, the joint end of the beam is dropped from above the other end and fitted, whereby the beam is joined to the column. Can be temporarily fixed on top. For this reason, even when the inclination angle of the beam is large, it is possible to prevent the beam from slipping off the pillar and causing danger. Furthermore, by simply forming the fitting part of the beam inside the tip of the beam,
The tip of the eaves of the beam can be easily formed, and energy can be saved by shielding solar radiation in summer and the like.

In the case where a fitting for joining wooden members is attached to one of the wooden members, for example, at the joint end of the column in advance at a factory or the like and transported to a building site or the like, the pillar is attached to the column along its axial direction. By attaching the wooden member joining fitting, it is possible to prevent the wooden member joining fitting from protruding in the lateral direction of the pillar. For this reason, many of the columns to which the wooden member joining fittings are attached can be laterally arranged and transported to a site or the like, so that the transport efficiency can be improved.

In the wooden member joining fitting according to another aspect of the present invention, the fixed portions fixed to the joining ends of the diagonal members such as climbing beams are connected to each other by hinges so as to be adjustable in angle. It can be used as a ridge fitting capable of coping with various inclination angles.

Further, the positions of the joining ends of the climbing beams and the like inserted into the respective fitting portions of the metal body are determined by the protrusions of metal fittings fitted into the positioning fitting portions of these joining ends. At the same time, a force for mutually pulling the joint ends of the climbing beams and the like acts, so that the coupling force between the climbing beams can be enhanced. Further, in a factory or the like, after the joining metal fittings are previously attached to the connection ends of the two climbing beams as ridge fittings, the two climbing beams are bent inward by the hinges of the joining metal fittings to be folded in half to the construction site. Because it can be transported,
The transfer efficiency can be improved.
