Description

The present invention relates to a joint structure used for a wooden member for construction such as a building panel in the case of constructing a wooden frame building, for example.

As a joining metal fitting used for a building panel, for example, there is one disclosed in the following Patent Document 1.

The joint fitting of Patent Document 1 abuts against a base attached to a longitudinal end of a shaft having the same thickness as a wire such as a pillar or a beam constituting a wooden frame building, and an end surface of the shaft at the base. It has a plate-shaped insertion portion provided on the contact surface and extending in the longitudinal direction of the shaft member. The base portion has two support plates arranged at intervals along the longitudinal direction of the insertion portion, and a cylindrical member having a screw hole is provided between the support plates.

When using, fasten the insertion part inserted into the shaft material with a drift pin, hold the joint fitting at the end of the shaft material, combine another shaft material, etc., and then bolt toward the cylindrical member of the base. Is inserted and joined with another shaft material or the like.

However, the joint fittings so far have been used as an intermediary between the wire rods, and the joint fittings have been bonded to the wire rods to be joined to each other with bolts or the like. Also, the bolts that secure the joint fittings to the wire were only for fastening.

For this reason, it has not been possible to fix building panels configured by connecting a wire rod corresponding to a pillar to a plate material or the like by using the conventional joining metal fittings. That is, since the building panel is larger in scale and heavier than the metal fittings, the degree of freedom of movement is lower than that in the case of joining wire rods to each other. In addition, it is necessary to process the building panel in a manner suitable for the joint fitting, as in the case of the wire rod, which complicates the shape of the building panel.

Therefore, it is a main object of the present invention to make it easy to join building panels to each other.

The means for that purpose includes a pair of joint fittings embedded in wooden members for construction to be joined to each other and a connecting shaft for connecting the pair of the joining fittings to each other, and the joining fitting is formed with a female screw extending in the joining direction. A male screw to be screwed into the female screw is formed on both sides of the connecting shaft in the longitudinal direction, and the connecting shaft having a diameter larger than that of the male screw is formed at a position biased to one side in the longitudinal direction of the connecting shaft. A rotary input portion to be rotated is formed, and the connecting shaft is connected to only one of the joining fittings by the female screw and the male screw, and the other joining fitting in the building wooden member combined in the joining form. It is a wooden member joining structure for construction in which the connecting shaft is sent out toward the female screw and the pair of joining fittings are connected to each other by the connecting shaft.

In this configuration, the connecting shaft connects the joining metal fittings that are embedded in the building wooden members such as building panels and building timber that are joined to each other and are housed in a fixed position. The connection by the connecting shaft is performed by rotating the connecting shaft, sending out the connecting shaft using the female screw and the male screw, and connecting the female screw and the male screw.

According to the present invention, the wooden members to be joined to each other are larger and heavier than the joining fittings because they are joined by connecting the embedded joining fittings with a connecting shaft that is screw-bonded to each other. Also, joining can be easily performed without fine processing according to the joining metal fittings. Therefore, it is easy to join the building panels to each other.

In addition, if a pair of joining metal fittings can be embedded in each wooden member and the connecting shaft can be sent from one joining metal fitting to the other joining metal fitting to be joined, the wooden member can be joined, which was impossible until now. It is possible to join members together. As such a wooden member, for example, there is a wall panel in which board members are attached to both sides and there is no space for joining members or hands necessary for work inside. Even such wall panels can be joined with a high degree of freedom.

FIG. 1 is a perspective view of a separated state, and FIG. 2 is a plan view (a) and a cross-sectional view (b) of the joined state. As shown in these figures, the building wooden member joining structure is a connecting shaft connecting a pair of joining fittings 13 and 15 embedded in a building panel 12 to be joined to each other and a pair of joining fittings 13 and 15. It is equipped with 17.

Here, first, the building panel 12 will be described.

The building panel 12 of this example enables the construction of a wooden frame building by combining them, and there are three types. That is, the shaft panel 12a as shown in FIG. 3, the frame panel 12b as shown in FIG. 4, and the shaft frame panel 12c as shown in FIG.

Each building panel 12 has a wire 21 that surrounds the periphery, a plate 22 stretched inside the wire 21, and an auxiliary material 23 that extends vertically and horizontally while being fixed to both the front and back surfaces of the plate 22. Is common in. However, the three types of building panels 12a, 12b, and 12c have different vertical members 21a extending in the vertical direction at both ends in the left-right direction as the wire rods 21.

That is, in the shaft panel 12a, the thickness of the vertical members 21a at both left and right ends is equivalent to the thickness of the wire rods (for example, 105 mm × 105 mm, 120 mm × 120 mm) such as pillars constituting the frame of the wooden frame structure. In the frame panel 12b, the thickness of the vertical members 21a at both left and right ends is thinner than the thickness of the wires constituting the frame of the wooden frame structure, for example, when the wires are 105 mm × 105 mm, the thickness is 105 mm × 30 mm. In the shaft frame panel 12c, the thickness of one of the vertical members 21a located at both left and right ends is the same as the thickness of the wire constituting the frame of the wooden frame structure, and the thickness of the other vertical member 21a. However, it is thinner than the thickness of the wire that constitutes the frame of the frame structure.

The building panel 12 may be provided with a wire rod equivalent to a wire rod such as a pillar or a beam inside like a bundle or a piercing member, or may be provided with a diagonal member such as a brace.

These building panels 12 are joined, for example, as shown in FIG. In FIG. 6, the portion surrounded by the thick line is one building panel 12, and in order from the left side of the drawing, the shaft panel 12a, the frame panel 12b, the shaft frame panel 12c (the left end is the shaft, the right end is the frame), and the shaft panel 12a. , The shaft frame panel 12c (the left end is the frame and the right end is the shaft) is combined.

Next, the joining fittings 13 and 15 and the portion of the building panel 12 in which the joining fittings 13 and 15 are embedded will be described.

The pair of joining metal fittings 13 and 15 are provided with main body portions 31 and 51 embedded in the building panel 12, respectively, and the main body portions 31 and 51 have female threads 32 and 52 extending in the joining direction of the joining metal fittings 13 and 15. Is formed. Since the main bodies 31 and 51 are embedded in the building panel 12, they are housed in a fixed position of the building panel 12, and the housed state is directly or indirectly held by some appropriate structure such as a drift pin or other member. Will be.

FIG. 7 shows a state in which the joining metal fittings 13 and 15 constituting the joining structure shown in FIG. 1 are separated. The joining metal fittings 13 and 15 shown in FIG. 7 are vertical to one of the joining metal fittings 13 embedded in the vertical member 21a as the axis of the shaft panel 12a or the shaft frame panel 12c and the frame of the frame panel 12b or the shaft frame panel 12c. The other joining metal fitting 15 embedded in the vicinity of the material 21a. One of the joining fittings 13 is a joining fitting 13 to which a connecting shaft 17 having male threads 71 and 72 screwed into the female threads 32 and 52 on both sides in the longitudinal direction is attached.

One of the joining metal fittings 13 illustrated in FIG. 7 is a cylindrical core member 33, and includes a cylindrical main body portion 31 inserted into a vertical member 21a as a wire rod constituting the building panel 12. Since the vertical member 21a is joined in the left-right direction of the building panel 12 in the horizontal direction, the insertion direction of the tubular core member 33 into the vertical member 21a is the left-right direction in the horizontal direction. The position where the tubular core member 33 is inserted is at least the upper end or the lower end of the vertical member 21a, and is a position where the horizontal member 21b extending to the left and right is joined.

The length of the main body 31 is set to be the same as or slightly shorter than the length of the vertical member 21a in the left-right direction. A through hole 34 orthogonal to the longitudinal direction is formed in the middle of the main body 31 in the longitudinal direction, and a female screw 34a is formed on the inner peripheral surface of the through hole 34 as shown in FIG.

The female screw 32 into which the connecting shaft 17 is screwed is formed on the inner peripheral surface of the main body portion 31 having a cylindrical shape. The female threads 32 are formed on both sides in the longitudinal direction, and these are a series of bolts that are longer than the tubular core member 33 and can be screwed so that the tip penetrates the tubular core member 33. Is. At both ends of the tubular core member 33, a single-character concave groove 35 that enables a rotation operation is formed.

The other joining metal fitting 15 illustrated in FIG. 7 is a plate-shaped core member 53, and the main body 51 is a rectangular insertion piece 51a inserted along the longitudinal direction of the horizontal member 21b as a wire rod constituting the building panel 12. And has a base portion 51b orthogonal to each other at the end of the insertion piece 51a. Since the horizontal member 21b is joined in the left-right direction of the building panel 12 in the horizontal direction, the insertion direction of the plate-shaped core member 53 into the horizontal member 21b is the left-right direction which is the longitudinal direction thereof. The position where the plate-shaped core member 53 is inserted is the end portion of the horizontal member 21b, which is the portion to which the vertical member 21a is joined.

The height (length in the vertical direction) of the insertion piece 51a is formed to be slightly shorter than the height of the horizontal member 21b, and the length is appropriately set. The insertion piece 51a has a plurality of through holes 55 for inserting the drift pin 54.

The width of the horizontal member 21b in the base portion 51b in the cross-sectional direction is set shorter than the width of the horizontal member 21b in the corresponding direction, and the thickness of the base portion 51b is appropriately set. As shown in FIGS. 9 and 10, the base portion 51b is composed of two base plates 56 arranged in parallel and a spacing member 57 fixed between them. 9A is a perspective view of the plate-shaped core member 53 as viewed from the base 51b side, and FIG. 9B is a perspective view of the plate-shaped core member 53 as viewed from the insertion piece 51a side. FIG. 10 is an exploded perspective view of the plate-shaped core member 53.

The space holding member 57 has a rectangular parallelepiped shape and is provided in the center of the base plate 56. The female screw 52 described above is formed so as to penetrate the entire base plate 56 and the spacing member 57 sandwiched between the base plate 56. The direction in which the female screw 52 extends is the same as the direction in which the insertion piece 51a extends. The diameter of the female screw 52 is the same as that of the female screw 32 of the cylindrical core member 33.

A notch 58 is formed at a position corresponding to the tip of the female screw 52 in the insertion piece 51a, as shown in FIG. 9B. The notch 58 is a portion that receives the connecting shaft 17 that protrudes from the female screw 52, and is formed into an appropriately shaped shape having a size that can be projected to a required length.

As shown in FIG. 7, the connecting shaft 17 has a shape of a shredded bolt as a whole, and a rotation input portion 73 having a diameter larger than that of the male screws 71 and 72 for rotating the connecting shaft 17 at a position biased to one side in the longitudinal direction. have. The rotation input portion 73 is formed in the shape of a hexagon nut.

The male screw 71 on one side in the longitudinal direction corresponding to the joint fitting 13 on one side of the rotation input portion 73 in the connecting shaft 17 is the male screw 71 on the proximal end side, and the male screw 72 on the other side in the longitudinal direction is another joint fitting, that is, A free-end side male screw 72 that is screwed into the other joint fitting 15.

The entire length of the connecting shaft 17, and the lengths of the base end side male screw 71 and the free end side male screw 72 are set to the required lengths. The required length of the connecting shaft 17 is at least a length that connects between the pair of joining fittings 13 and 15 built in the building panel 12, and a length that provides sufficient coupling with the joining fittings 13 and 15. It is the length obtained by adding the length considering the moving length of.

Since the connecting shaft 17 illustrated in FIG. 7 also has a function of holding one of the joining fittings 13 to the building panel 12, the length of the base end side male screw 71 is formed longer than the above-mentioned length. is doing. That is, the connecting shaft 17 is formed to have a length having an extra length portion 71a that penetrates the tubular core member 33 that is one of the joining metal fittings 13 and projects to the opposite side, and the building panel 12 is attached to the extra length portion 71a. It is configured to screw the joining metal fitting 18 for joining the constituent wire rods 21.

The metal joint 18 is for connecting the horizontal member 21b of the building panel 12 to the vertical material 21a, and the structure of the metal joint 18 is the same as that of the plate-shaped core member 53 described above. Briefly, the metal joint 18 includes a main body portion having an insertion piece 18a and a base portion 18b, and the base portion 18b is formed with a female screw 18c penetrating in the thickness direction thereof. The insertion piece 18a has a through pain hole 18d into which the drift pin 19 is inserted.

The pair of joining metal fittings 13 and 15 described above are composed of a cylindrical core member 33 and a plate-shaped core member 53. For example, the tubular core members 33 and the plate-shaped core members 53 form a pair of joining metal fittings. In some cases. Hereinafter, the "pair of joining metal fittings" 13 and 15 are also referred to as "a set of joining metal fittings" 13 and 15.

The fixing portion of the building panel 12 to which the pair of joining metal fittings 13 and 15 and the connecting shaft 17 are fixed is configured as follows.

That is, the building panel 12 for fixing the cylindrical core member 33 and the metal joint 18 is for inserting the accommodating slit 24 for accommodating the metal joint 18 and the drift pin 19 for fixing the insertion piece 18a at the end of the horizontal member 21b. It has a through hole 25. The accommodating slit 24 has a narrow portion 24a for accommodating the insertion piece 18a and a wide portion 24b for accommodating the base portion 18b.

At the end of the vertical member 21a to which the horizontal member 21b is connected, a joint fitting holding hole 26 for accommodating the tubular core member 33 is formed. As shown in FIG. 2, a counterbore 26a is provided on one side surface of the vertical member 21a in the direction orthogonal to the joint fitting holding hole 26, and a bolt hole 26b extending toward the through hole 34 of the cylindrical core member 33 is provided. Is formed. A bolt 36 is inserted into the bolt hole 26b to hold the tubular core member 33 non-rotatably.

The building panel 12 for fixing the plate-shaped core member 53 has an accommodating slit 24 for accommodating the plate-shaped core member 53 and a through hole 25 for inserting a drift pin 54 for fastening the insertion piece 51a at the end of the horizontal member 21b. Have. The accommodating slit 24 has a narrow portion 24a for accommodating the insertion piece 51a and a wide portion 24b for accommodating the base portion 51b.

The end portion of the vertical member 21a to which the horizontal member 21b is bonded has a notch portion 27 in a necessary range. The notch portion 27 is a space for rotating the rotation input portion 73 of the connecting shaft 17.

Using the pair of joining metal fittings 13 and 15 configured as described above and the connecting shaft 17, the vertical member 21a portion as the axis of the shaft panel 12a or the shaft frame panel 12c and the frame of the frame panel 12b or the shaft frame panel 12c. When joining the vertical member 21a portion as described below, the procedure is as follows.

First, as shown in FIG. 1, in the tubular core member 33, which is one of the joining fittings 13, the joining metal fitting 18 is fixed to the end of the horizontal member 21b with a drift pin 19, and then the joining fitting holding hole of the vertical member 21a is held. It is inserted into 26 and fixed using a bolt 36. A male screw 71 on the base end side of the connecting shaft 17 is screwed into the tubular core member 33, and the extra length portion 71a is screwed into the female screw 18c of the metal joint 18 through the tubular core member 33. That is, the connecting shaft 17 is connected to only one of the joining fittings 13 by the female screw 32 and the base end side male screw 71. At this time, the rotation input portion 73 of the connecting shaft 17 protrudes from the side surface of the vertical member 21a.

The plate-shaped core member 53, which is the other joining metal fitting 15, fixes the joining metal piece 18 to the end of the horizontal member 21b with a drift pin 19. At this time, the end surface of the base portion 51b of the plate-shaped core member 53 is flush with the end surface of the horizontal member 21b, and the female screw 52 is exposed toward the cutout portion 27.

In this state, the joining work is performed as shown in FIG.

As shown in FIG. 11A, the building panel 12 in which the other joining metal fitting 15 is embedded is moved toward the building panel 12 in which the one joining metal fitting 13 is embedded, and the vertical members 21a are butted against each other. .. That is, it is combined with the joining form. Subsequently, as shown in FIG. 11B, the rotation input portion 73 of the connecting shaft 17 is rotated through the notch portion 27, and the connecting shaft 17 is sent out toward the female screw 52 of the other joining fitting 15 to be connected. A pair of joining metal fittings 13 and 15 are connected to each other by a shaft 17. At this time, as shown in FIG. 2A, the rotation input portion 73 is brought into contact with and pressed against the base portion 51b of the other joining metal fitting 15 facing the other.

In this way, the joining work is completed.

As described above, the building panels 12 to be joined to each other are joined by being combined in a predetermined joining form and then being sent out toward the other joining fitting 15 by rotating the connecting shaft 17.

Therefore, even if the building panel 12 is larger and heavier than the joining metal fittings 13 and 15, the building panel 12 can be easily joined without fine processing according to the joining metal fittings 13 and 15. ..

Moreover, since the operation for joining is only to rotate the connecting shaft 17 and send it out, the work is very simple. Further, since the rotation input portion 73 of the connecting shaft 17 is formed to have a diameter larger than that of the male threads 71 and 72 and comes into contact with the opposing joining fittings 15 when the joining fittings 13 and 15 are connected to each other, a good joining state can be obtained. ..

Further, since the set of joining metal fittings 13 and 15 is composed of the cylindrical core member 33 and the plate-shaped core member 53, each configuration is simple and can be manufactured at low cost, and also has a vertical member 21a as a shaft. The portion and the portion having the vertical member 21a as a frame can be rationally joined. Further, since the connecting shaft 17 attached to the cylindrical core member 33, which is one of the joining metal fittings 13, has an extra length portion 71a, the number of parts required for the configuration of the building panel 12 can be reduced.

As a result, for example, as shown in FIG. 6, the shaft panel 12a, the frame panel 12b, and the shaft frame panel 12c can be easily joined, and the wooden frame building can be safely constructed even by a non-skilled worker. Have.
