BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting fitting for a building material connecting fitting and a building material fitting set comprising the connecting fitting and a building material connecting fitting, and more particularly to a building such as a middle-folded roof of a wooden house. In particular, the present invention relates to a connection structure for a building material suitable for connecting the ends of the building material to each other.

2. Description of the Related Art Conventionally, in the wooden frame construction method, pillars,
When connecting timbers such as beams and girders to other timbers, the connecting timbers (chin hanging metal fittings, beam receiving metal fittings) are attached to one of the timbers without the use of mortar processing, and the other timber with bolt shafts attached. By engaging with the connection metal fittings, a method for safely constructing a wooden house by a simple work is implemented.

According to this method, by simply forming a simple structure which can be processed by an automatic tool or the like at the end of the other wood,
It is possible to obtain a good appearance in which the metal fittings are hardly visible to the outside, and to obtain sufficient rigidity to withstand not only the weight of the building but also an earthquake or the like. In addition, since there is no need for sumiing or jointing for joining timbers, the preparation is simple and the joining work is easy, so that skilled workers are not required and the construction period can be shortened.

The connecting fitting used in this method is, for example, a fixed surface portion fixed to one piece of wood, and is bent from both sides of the fixed surface portion and extends substantially vertically, and is formed in parallel with each other at a predetermined interval. It has a pair of support surface parts, and the support surface part is provided with a shaft engaging jaw part having an opening at its peripheral edge and a shaft insertion hole formed in the plate surface. in this case,
At the end of the other piece of wood, two split grooves are formed to accommodate a pair of supporting parts, and the tip of the part sandwiched by these split grooves is slightly cut off to form a recess. . At least two shaft holes penetrating between the side surface parts are bored in the end part of the other timber thus formed, and one of them is previously inserted with an engaging shaft such as a bolt shaft or a pin. And fix it.

The end of the other wood processed in this way is
When the support parts of the connection fittings are fitted from above, the pair of support parts are housed in the split groove parts, and the engagement shafts engage with the shaft engaging jaw parts formed on the support parts. Another shaft hole preformed in the other timber thus engaged,
By inserting the other engaging shaft into the shaft inserting hole formed in the support surface portion, one wood piece and the other wood piece can be completely connected.

[0006]

In the wooden frame construction method using the above-mentioned connecting metal fittings, due to its structure, when a building material that is inclined obliquely is attached, such as climbing on the roof of a house, the metal fittings are made of wood. There is a problem that it will stick out and impair the appearance and interfere with the arrangement of other building materials.Conversely, in order to prevent the metal fitting from protruding from the wood, it is necessary to make the metal fitting considerably smaller than the diameter of the wood. Therefore, there is a problem that the mechanical strength of the joint cannot be secured.

Further, particularly in the roof portion of the conventional wooden house, if the slope of the roof is increased, the attic portion becomes relatively large with respect to the height of the building, and the ratio of the living room space to the building space decreases. On the contrary, if the slope of the roof is reduced, the attic part can hardly be used,
Since the extension line of the roof will reach the ground surface part far from the building, even if you try to build a high-rise house with three or more floors facing a narrow road, you must build a vacant land on the site according to the building standards. It may not be possible to build a house.

For this reason, the roof is formed as a folded roof, the slope of the upper part of the roof is made gentle, and the slope of the lower part of the roof is made steep, so that the space available for the attic is secured and the site is small. There is a way to build a high-rise house. However, in this case, the number of joints of timber increases in order to form a center-folded roof, and timbers that are inclined together must be joined together, which requires skill and labor of work. is there. In addition, it is necessary to erect a pillar in the middle bent part (the part where the two trees are connected) to which the trees are connected, and the space for the corner attic part is secured by the existence of this column. However, there is a problem that it cannot be used effectively.

Therefore, the present invention solves the above-mentioned problems, and the problem is to construct a new metal fitting that easily realizes a direct connection between the ends of two or more building materials. We have realized a new connection structure that enables the connection of building materials that are inclined to each other without using a bridge, which makes it possible to easily form a folded roof and make effective use of the site, as well as the effective use of the attic. The purpose is to enable the construction of high-rise houses with comfortable habitability.

A plurality of linked bodies of the climbing trees C and D are arranged in the extension direction of the purlin A or the girder B. The connecting fitting 30 for connecting the climbing trees C and D is formed with supporting surface portions 32, 32 shown in FIG.
A cross bar G as a cross member is connected to 2. The other end of the crosspiece G is connected to a support surface portion 32 of another connecting fitting 30 that connects adjacent climbing trees C and D.

Since one of the pair of left and right supporting surface portions 32 for connecting to the cross bar G is not required as the connecting fitting used for the roof gable portion, one supporting surface portion 3
It suffices to prepare a connecting fitting 30 ′ provided with only 2 and use this.

The above-mentioned joining fitting 10 and connecting fitting 30,
The details of the connection structure between the climbing trees C and D and the cross tree G are shown in FIG. The same end structure is formed on the climbing trees C and D, and they are connected to the supporting portions 12 of the connecting fittings 10 and 10, respectively. FIG. 3 shows the structure of the end C1 of the tree C. Edge C1
Two split groove portions C2, C2 are formed in the groove, and a concave portion C3 is formed by cutting off the tip of the central portion C4 sandwiched by the split groove portions C2. Further, two upper and lower shaft holes are formed so as to horizontally insert the two split groove portions C2, the lower shaft hole C5 is left as it is, and the bolt shaft C6 is inserted and fixed in the upper shaft hole. ing.

When the end portion C1 of the climbing tree C is dropped from above the connection fitting 10 and the split groove portions C2 and C2 are arranged so as to accommodate the support portions 12 and 12, the bolt shaft C6 (to the engaging shaft 42 in FIG. 1). The same) engages the shaft jaws 13, 13. In this state, the shaft hole C5 is arranged concentrically with the shaft insertion hole 14, and the bolt shaft and the metal pin (the same as the engagement shaft 43 in FIG. 1) are press-fitted therein, The connection fitting 10 and the climbing tree C are completely connected. The shaft hole is formed so as to correspond to any of the other shaft insertion holes 16, 17, and 18 as needed, and the engagement shaft is similarly inserted.

On the other hand, one split groove portion G2 is also formed at the end portion G1 of the crossbar G, and two upper and lower shaft holes are formed so as to pass through the split groove portion G2 in the same manner as described above. A bolt shaft G3 is inserted and fastened in the hole. The lower axial hole C4 remains unchanged. With respect to this cross member G as well, when the end portion G1 is dropped from above so that the split groove portion G2 accommodates the support surface portion 32 of the connecting fitting 30, the bolt shaft G3 engages with the shaft engaging jaw portion 33. In this state, the shaft hole G4 and the shaft insertion hole 34
Are arranged so as to be concentric with each other, and the crosspiece G is completely connected to the connecting member 30 by inserting and fastening a bolt shaft or press-fitting a metal pin into them. Similarly, the shaft hole may be formed so as to be concentric with the shaft insertion hole 35, and the engagement shaft may be inserted therein.

In addition, the shaft insertion hole 14 of the connection fitting 10,
16, 17, 18 and shaft insertion holes 34, 35 of the connecting fitting 30
Are formed by shifting the vertical position and the front-rear position respectively, so by selecting and using multiple shaft insertion holes that exist in dispersed directions with respect to the direction in which stress is applied,
It is possible to distribute the load applied to the shaft hooking jaw and each shaft insertion hole almost evenly and to bear the load.

FIG. 4 shows the connecting fitting 10 and the connecting fitting 3 described above.
The explanatory view for demonstrating the inclination angle of the climbing tree applicable to the combined body with 0 is shown. The supporting surface portions 12 of the two connecting metal fittings 10 fixed on both front and back sides of the mounting surface portion 31 of the connecting metal fitting 30.
As shown in the figure, both have an upper edge 12a and a lower edge 12b having a predetermined inclination angle θ with respect to the fixed surface portion 11 of the connection fitting 10. Therefore, when the trees C and D are mounted completely along the upper edge 12a and the lower edge 12b, the intersection angle between the trees C and D connected to the support 12 is 2θ.

However, the support portion 12 of the connection fitting 10 is formed to be slightly smaller than the diameter of the trees C and D and the vertical width of the mounting surface portion 31, and further, the cut portion 15 is formed at the tip of the lower end edge 12b. Has been done. Therefore, the connection fitting 10
Is configured to be able to cope with the inclination angles φ and ψ of the climbing trees C and D within a certain range.

That is, each of the connecting fittings 10 can cope with a certain degree of variation in the inclination angles of the trees C and D (shown by the broken line I, the one-dot chain line II and the two-dot chain line III in the figure). The range of tilt angles that can be supported by the connection fitting 10 is θ ±
If δ is set, the possible range of the angle φ + ψ between the trees C and D is 2 (θ ± δ), so that it is possible to cope with an extremely wide tilt angle. Therefore, by connecting the two connecting metal fittings 10 and 10 using the connecting metal fitting 30, it is possible to cope with almost all roof inclination angles.

As described above, since the combined body of the connecting fitting 10 and the connecting fitting 30 can be adapted to various angles between building materials, for example, a two-dot chain line X shown in FIG.
The angle of the center-folded roof can be changed appropriately as indicated by the dotted line Y. The connection metal fitting 10 can be used without any problem as long as the angle of the middle bent portion of the middle-folded roof is within the allowable angle range of the inclination angle of the support surface portion 12 of the connection metal fitting 10. If two types of connecting metal fittings with different θ are formed, it is sufficient for most sites.

For example, as the corresponding range θ ± δ of the inclination angle of one connecting fitting, the range from 3 inch gradient to quadrature gradient (45 degrees), and the other connecting fitting from 7.5 inch gradient to 20 inch.
It may be set up to a range up to a dimensional gradient, and by combining these same or different types of connecting fittings, it can be used for connecting a very wide range of building materials.

In FIG. 5, the connection fittings 10 are attached to the purlin A, and the different connection fittings 20 are attached to the girder B, so that each of the connection portions when the roof using the climbing trees C and D is constructed. It is explanatory drawing explaining a structure. These connecting structures include three connecting fittings 10, one connecting fitting 30,
It can be configured with one connection fitting 20.

The connecting fitting 20 has a fixed surface portion 21 fixed to the upper surface of the girder B by a bolt shaft or the like, and a pair of support surface portions 2 bent from both sides of the fixed surface portion 21 and extending in the vertical direction.
2 and 22 are provided. Side edges 20a and 20b that are inclined in the same direction are formed on the support surface portion 22, and a cut portion 25 is formed at the upper end of the side edge 20b.

The support surface portion 22 has a shaft engaging jaw portion 23 having an opening at its upper edge and a shaft insertion hole 24 formed on the side thereof.
Are provided. The shaft engaging jaw 23 is engaged with a bolt shaft attached to the lower end of the climbing tree C, and the shaft insertion hole 24 is a bolt shaft inserted into the shaft hole formed in the lower end of the climbing tree C or It is inserted through a metal pin.

As described above, by using the connecting fittings 10 and 20, it is possible to connect the connecting body composed of the climbing trees C and D to the purlin A and the girder B. As described above, the connecting fitting 10 can be used at the connecting portion between the trees C and D by being connected to the connecting fitting 30 and also at the connecting portion between the purlin A and the building D.

Here, in FIG. 5, the connecting fitting 20 is attached to the upper end surface of the girder B, but when the inclination angle of the climbing tree C is not so large, the connecting fitting 20 is used instead of the connecting fitting 20.
A connecting metal fitting 40 (shown by a dotted line in the figure) having a structure similar to that of the connecting metal fitting 10 and having an inclination angle of the supporting surface upside down with respect to the connecting metal fitting 10 is attached to the side surface of the girder B, and the climbing tree C is attached thereto. You may connect. This fitting 40 can be used to connect a normal roof climbing, which is not usually a mid-fold, to the girder. The adaptability to the range of the inclination angle of the climbing tree is the same as the above case, and has a certain allowable range.

FIG. 6 shows an example of a connecting fitting having another structure which can be used in place of the connecting fittings 10 and 40. The connection fitting 50 includes a fixed surface portion 51 similar to the one described above, and a pair of support portions 52, 52 that are bent from both sides of the fixed surface portion 51 and extend vertically. The support portion 52 has an upper edge 52a inclined by a predetermined angle.
And a lower edge 52b is formed. In this support portion 52, in addition to the shaft jaw 53 having an opening at the upper edge 52a,
A shaft jaw 54 having an opening is provided at the lower edge 52b.

The support portion 52 of the connecting fitting 50 has a shaft insertion hole 55 at an intermediate position between the two shaft engaging jaws 53 and 54.
Besides, the two shaft insertion holes 56 and 57 are vertically arranged closer to the fixed surface portion 51 than these.
Further, the lower end edge 5 is attached to the supporting portion 52 of the connecting fitting 50.
Cut portions 58 and 59 are formed in the tip portion of 2b and the base portion of the upper edge 52a, respectively. These cut portions 58 and 59 partially reduce or make horizontal the inclination angles of the lower edge 52b and the upper edge 52a, respectively, thereby expanding the applicable range of the inclination angle of the timber to be connected using the connecting fitting. It was created for this purpose.

This connecting fitting 50 is the connecting fitting 30 described above.
Connection fitting 1 that is connected to the purlin A as well as connected to
It can also be used as the connection fitting 40 attached to the side surface of the above-mentioned girder B. When used as the connecting fitting 10, the shaft jaw 53 having an opening at the upper end edge 50a is used, and when used as the connecting fitting 40, the fitting is turned upside down and the shaft having an opening at the lower end edge 50b is used. The hanging jaw 54 is used.

According to this connecting fitting 50, since the same connecting fitting can be used for both the upper end and the lower end of the inclined climbing trees C, D, it is possible to reduce the kinds of connecting fittings and to reduce the manufacturing cost and the manufacturing cost. The labor for management can be reduced. Further, by forming the plurality of shaft insertion holes 55, 56, 57, it is possible to change the shaft insertion hole to be used depending on whether it is connected to the upper end of the climbing tree or connected to the lower end of the climbing tree. Therefore, the stress received by the metal fitting can be shared by the shaft engaging jaws and the plurality of shaft insertion holes, and the strength and durability of the connecting portion can be enhanced.

For example, when connecting to the upper end of the climbing tree D, the engaging shafts are inserted through and fixed to the shaft engaging jaws 53 and the shaft inserting holes 55 and 57, and When connecting to the lower end, in addition to the shaft jaw 54, the shaft insertion holes 55 and 5
The engaging shaft is inserted through these and fixed by using 6. As a result, the stress applied to the connection fitting 20 can be almost evenly shared by the shaft engaging jaw and the two shaft insertion holes.

Next, a modification of the connecting fitting according to the present invention will be described. As shown in FIG. 7, this connecting fitting 60
Is made by stacking two metal plates, and
Attaching portions 61, 61 forming an attaching surface portion formed so that 0 and 10 can be attached to the front and back, bent portions 62, 62 bent at both left and right ends of the attaching portion 61, and a tip of the bent portion 62. It is comprised from the support parts 63 and 63 which comprise the formed support surface part. In this case, the mounting surface portion has substantially the same structure as that of the above-described embodiment because the two mounting portions 61, 61 are simply superposed on each other, but the supporting surface portions are parallel to each other with a predetermined interval. It differs from the above-described embodiment in that it is configured by a pair of supporting portions 63 provided in the.

Since the pair of supporting portions 63 are respectively provided with the shaft engaging jaws 64 and the shaft insertion holes 65, the width of the split groove is increased by the same method as described above to form a horizontal member. Crossbars can be connected. As a result, the shaft jaw 6
Since 4 and the shaft insertion hole 65 are arranged in a pair with a predetermined interval, respectively, the stability of the engaging shaft attached to the cross bar is enhanced, and the rigidity for preventing rotation around the axis of the cross bar is improved. To do. In addition, the support portion 6 of the connecting fitting 60
Similarly to the support surface portions 12 and 12 of the connection fitting 10, 3 and 63 can be connected by forming two split grooves at the ends of the cross bar.

In this connecting fitting 60, the mounting portion 6
Two plate members each having a bending portion 62, a bending portion 62, and a supporting portion 63, that is, metal plates are stacked on each other. In this way, since the respective metal plates can be manufactured extremely easily by pressing, it is possible to construct them integrally (for example, a structure in which two supporting parts are connected to one mounting surface part). Compared with this, processing such as welding becomes unnecessary, and the manufacturing cost can be greatly reduced.
In addition, the two metal plates are connected to each other as shown in the drawing.
Since they are sandwiched between 0 and fixed to each other, it is not necessary to perform processing such as adhering metal plates to each other.

FIG. 8 shows the structure of the connecting fitting 70 similar to that described above. A similar structure of this connecting fitting 70 is shown in FIG.
It is also shown in (b). In the connecting fitting 70, the mounting portion 71 and the bent portion 7 are the same as the connecting fitting 60.
2. It is the same as the above in that it is configured by stacking two metal plates having the support portion 73, the shaft engaging jaw portion 74, and the shaft insertion hole 75. However, in this embodiment, a pair of shaft engaging jaws 74 is provided on both sides of the upper end edge and the lower end edge of the support portion 73. In this connecting fitting 70, the two metal plates have exactly the same shape, and it is not necessary to form a pair of symmetrical metal plates as in the connecting fitting 60, so that the manufacturing cost can be further reduced and Improves on-site handling.

In this case, as shown in FIG. 9 (a), the mounting portion 71 may be provided with supporting portions 73 'and 73 "whose upper and lower edges are inclined. Part 7
In 3 ′ and 73 ″, the support portion 73 ′ is inclined upward from the attachment portion 71, and the support portion 73 ″ is inclined downward from the attachment portion 71, but both the left and right support portions are upward or downward. You may incline to either of the downward direction.

As described above, since the supporting surface of the connecting fitting is also formed to be inclined, it is possible to form various structures in which the cross member, which is a cross member, is also inclined. It is possible to realize a more complicated frame structure without providing it. For example, it is possible to form a pyramid-shaped or polyhedral roof or dome.

FIG. 10 shows a usage method in which the above configuration is further applied. In this method, the mounting surface 81 of the connecting fitting 80 similar to the connecting fitting shown in FIG.
The attachment surface portion 91 of the new connecting fitting 90 is sandwiched between the fixing surface portion 0 and the fixing surface portion 0. Connecting fitting 9
0 consists of two metal plates formed in a structure in which the support surface portion 93 extends from one side of the mounting surface portion 91 via the bent portion 92.

Fixing holes are formed in the mounting surface portion 91 at positions corresponding to the fixing holes formed in the mounting surface portion of the connecting fitting 80 and the fixing holes formed in the fixing surface portion of the connecting fitting 10.
