Description

  The present invention relates to a metal fitting for a wooden member in a wooden building, and more particularly to a bonding plate as a metal fitting suitable for use with a metal fitting body having slits formed in the vertical direction.

2. Description of the Related Art Conventionally, various techniques related to architectural fittings have been devised and provided.
The present inventor has also proposed and put to practical use a number of architectural fittings as a leading expert in the development of architectural fittings.
However, most of the conventional joint fittings for construction are related to shaft joints such as pillars and beams, torches, foundations, etc., and as joint fittings used for roof frames, the present inventor's Japanese Patent Publication 8- Only a few things can be seen, such as those related to 33041. In particular, there were almost no joint fittings used for the frame of the dormitory roof.
Japanese Patent Publication 8-33041

  As described above, the roof, in particular, the dormitory roof, has not been put to practical use, and has been framed by a conventional construction method. FIG. 14 is a partially omitted perspective view showing a roof structure of a dormitory roof by a conventional construction method of a Western style hut.

In the conventional construction method shown in the figure, a purlin 101, two corner joints 102 (one is omitted), two flat joints 103, and one wife joints are formed above the corner bundle 100. 104 is joined by a joint.
For this reason, the joint processing for each joint becomes complicated, requiring a lot of work, and at least five joints must be processed on the outer circumference of the same height of one corner true bundle. The strength was not enough.

Also, when building the roof, the corner bundles 100 are centered, the ends of a plurality of joints (two corner joints 102 and three flat / wife joints 103, 104) are joined, and purlin 101 was performed.
In addition, since this joining work needs to be performed at a construction site where the scaffolding is high at a high place, the work efficiency is low and there is a problem in terms of safety.

In order to avoid complicated processing work and joining work at high places, a method of assembling and joining the entire roof in advance and then placing it on the building is also employed.
However, in this case, a work space for assembling and joining the entire roof in advance is required at the construction site, and a large crane for placing the completed roof on the building is required.

  The present invention has been made in view of the above problems. For example, even when a roof is assembled at a high place on a construction site, a large number of palms can be easily joined to a corner bundle. The purpose of the present invention is to provide a joining plate with improved safety and speed of joining work.

  In order to achieve the above object, the architectural fitting according to claim 1 of the present invention is a joining plate for a flat plate member used as an architectural joining bracket together with a metal fitting body having a slit in the vertical direction, in front of the flat plate member. A locking portion for locking with the slit is provided on the lower side, and a bolt hole for inserting a joining bolt with a wooden member is formed from the center portion to the rear portion of the flat plate member.

  Moreover, in this invention, the said latching | locking part can be set as the structure which has a recessed part latched with the bottom part of the said slit, and an inclined part which spreads forward from this recessed part.

  Moreover, in this invention, the upper side and lower side from the center part of the said flat plate member to a rear part can be made into the upper oblique side and lower oblique side which have the inclination of the same angle as the attachment gradient of the said wooden member with respect to the said metal fitting main body.

  In the present invention, the wooden member is two types of wooden members having different mounting gradients, and the upper oblique side is inclined at the same angle as the mounting gradient of one of the two types of wooden members. The lower hypotenuse can be inclined at the same angle as the mounting gradient of the other wooden member of the two types of wooden members.

  In the present invention, the flat plate member has a plurality of bolt holes for attaching the wood member to the metal fitting body at different attachment angles.

  Further, in the present invention, the number of bolt holes drilled in the longitudinal direction of the rear part of the flat plate member is twice the number of bolt holes drilled in the longitudinal direction of the central part. Among these, the positional relationship between one bolt hole and the bolt hole drilled in the central vertical direction is substantially parallel to the upper oblique side, and the position of the other bolt hole and the bolt hole drilled in the central vertical direction The relationship is substantially parallel to the lower hypotenuse.

As described above, the joining plate of the present invention does not require complicated joint processing, and can simplify the joint processing of the wooden member, so that the processing time can be shortened, and further, the joining of the wooden member can be performed. Strength can be improved. Further, even when a large number of wooden members are joined to the metal fitting body, they can be joined efficiently.
In addition, since the joint plate can be shared, the working efficiency can be improved and the manufacturing cost of the joint plate can be reduced by sharing.

Hereinafter, embodiments of the joining plate of the present invention will be described with reference to the drawings.
First, an embodiment of a metal fitting body used with the joining plate according to the present invention will be described.

  Here, the metal fitting body 1 has slits 12 formed downward from the upper end of the cylindrical member 10 at positions where the cylindrical member 10 is divided into eight equal parts in the circumferential direction. 2a and 2b are locked.

As described above, since the slit 12 has the opening 13 in the upper part of the cylindrical member 10, the joining plates 2a and 2b can be easily inserted into the slit 12, and the work when joining the joining plates 2a and 2b is performed. Can be improved.
Further, by forming the opening 13, the longitudinal dimension of the metal fitting body 1 can be reduced, and the metal fitting body 1 can be reduced in size and weight.

  In addition, it is preferable to form guide slopes 14 on both sides of the opening 13, so that when the joining plates 2 a and 2 b are inserted into the slits 12, even if the positions of both are slightly shifted, the joining plate 2a and 2b are engaged with the slit 12 while being guided by the guide inclination 14, and the workability can be further improved.

  In addition, the formation position of a slit is not limited to what was formed in the opening part of the said slit 12, You may provide a slit in the intermediate part of the cylindrical member 10, for example. In this way, even if the pressing member 5 is omitted, it is possible to prevent the joining plates 2a and 2b from coming off to some extent.

Further, a shaft bolt hole 15 through which a shaft bolt 32 to be described later penetrates is formed in the center portion of the flange 11, and the metal fitting body 1 is attached to the main tree by tightening a nut to the shaft bolt 32 that is penetrated. It can be easily fixed to the upper part of the member.
Furthermore, a bolt hole 16 for fastening a thick plate member 4 to be described later is formed at a position where the flange member 11 is divided into four equal parts in the circumferential direction.

In addition, although the slit 12 is formed in eight places, the metal fitting main body 1 is not limited to this structure, for example, when there are four splint members according to the number of splint members to be joined. May have a structure in which slits 12 are formed at four locations.
The metal fitting body 1 uses the cylindrical tubular member 10, but is not limited to this, and may be, for example, a polygonal shape, and an octagonal cylinder like the metal fitting body 1 a shown in FIG. 2. It can also be set as the structure using the shaped member 10a.

Next, an embodiment of a joining plate according to the present invention will be described.
For ease of understanding, a case where a palm and a purlin are used as splint members will be described.
[Structure of joining plate]
FIG. 3: has shown the schematic for demonstrating the structure of the joining plate of the joining metal fittings for construction of 1st embodiment which concerns on this invention, (a) is a front view of the joining plate for joints, (b) Is a side view of the joining plate for joints, (c) is a front view of the joining plate for purlins, and (d) is a side view of the joining plate for purlins.

In the same figure, a joining plate 2a for joining the palms and a joining plate 2b for purlins are made of a flat plate member such as a steel plate, and a locking portion that is locked to the slit 12 of the metal fitting body 1 below the flat plate member. 20 is formed. Further, bolt holes 21 are formed from the central part to the rear part of the flat plate member for fixing to the palm and purlin with bolts and nuts.
Here, the locking portion 20 forms a concave portion 22a for firmly locking with the slit 12, and an opening portion is provided on the opposite side of the concave portion 22a from the bolt hole 21, that is, on the front portion continuous with the concave portion 22a. An inclined portion 22b that expands toward the top is formed, and the joining plates 2a and 2b are shaped to be easily locked to the slit 12.

The joint plate for joint 2a has a lower hypotenuse 23 having an inclination of the same angle as the slope of the corner joint (corner slope) and an inclination of the same angle as the slope of the flat joint and the wife joint (flat slope) from the center to the rear. The upper oblique side 24 having a shape.
Further, the jointing plate 2a for the palm is provided with four bolt holes 21 and 21a, 21 and 21a substantially parallel to the lower oblique side 23, and four bolt holes 21 and 21b substantially parallel to the upper oblique side 24. , 21 and 21b are drilled. Of these bolt holes, the two bolt holes 21 and 21 on the center side are shared.

  In this way, it is possible to share the joint plate for corner joints and flat joints with different slopes (the wife joint is the same slope as the flat joints), and the manufacturing cost of the joint plate can be reduced. Can do. Also, workability can be improved in the assembly work.

The purlin joining plate 2b has a rectangular structure in which four bolt holes 21 are formed.
Here, the distance “L” from the locking portion 20 to the upper surface may be constant for the joining plate to be used, for example, the joining plate 2a for the palm and the joining plate 2b for the purlin, and will be described later. By bringing the pressing member into contact with these upper surfaces, the engagement state of the joining plate can be easily maintained.

Although not shown in the figure, the palms and purlins have through holes formed at positions corresponding to the bolt holes, and the bolts are inserted into the through holes and the bolt holes, and the nuts are screwed together to join. The plate can be easily fixed to the purlins.
Further, the shape of the joining plate and the position and quantity of the bolt hole are examples when the splint member is a palm and purlin, and has various shapes and positions and quantities of the bolt hole according to the splint member. A joining plate can be used.

Next, the structure of the fixing means for the metal fitting body will be described.
[Structure of fixing means]
FIG. 4 shows a schematic front view for explaining one embodiment of the fixing means.
In the figure, the fixing means comprises a shaft member 30a, a shaft bolt 32 made up of all screws, and a nut 33.
Here, the shaft member 30a has a structure in which a female screw 30c is processed in the upper part and a pin hole 30b is formed in the lower part.

  Further, a square tenon 41 is formed at the upper end of the main wood member, and a thick plate member 4 in which a tenon hole 42 fitted to the square tenon 41 is formed is provided on the lower surface of the flange 11. If it does in this way, since the flange 11 is joined to the main wood member at an angle determined by the fitting of the square mortise 41 and the mortise hole 42, it is possible to increase the joining strength in the circumferential direction and to rotate the metal fitting body. Deviation in the direction can be effectively prevented.

In the fixing means having the above configuration, the shaft member 30a is embedded in the main tree member, and although not shown, the pin 31 described later is fixed to the main tree member by being inserted into the pin hole 30b. The
Then, the shaft bolt 32 is inserted into the shaft bolt hole 15 of the flange 11 placed on the upper portion of the main wood member, and is screwed with the female screw 30c. Further, the nut 33 is screwed with the shaft bolt 32. The flange 11 is fixed to the main wood member.

  The fixing means is a technique proposed by the present inventor in Japanese Patent Application No. 8-114161, and is not limited to the above configuration. For example, a male screw is processed instead of a female screw, and a shaft It is good also as a structure which uses a nut instead of a volt | bolt.

  According to the above-described metal fitting, the bonding plate, and the architectural fitting having the fixing means, it is only necessary to provide a groove for pushing the bonding plate into the splint member, so that it is not necessary to perform complicated joint processing. The processing time required for the mouth processing can be shortened, and the joining strength of the splint member can be increased.

Note that the splint member is a wooden member used for purlins, joints, and the like, and is usually composed of an interposer and two standard members joined so as to sandwich the interposer.
Here, it is preferable that the thickness of the joining plate is substantially the same as the thickness of the intervening plate. By doing so, the joining plate can be pushed into the intervening plate space described later, so that the processing time of the groove into which the joining plate is pushed in Can be further shortened.

Next, a usage example using the above-described joint fitting for building will be described with reference to the drawings.
First, as shown in FIG. 5, in the dormitory roof of a Western-style hut, the corner true bundle 70 with the metal fitting body 1 fixed to the upper part, the purlin 71, the corner joint 72, the flat joint 73, and the wife joint 74 are joined. This usage example will be described.

[Example of use]
FIG. 6: has shown the schematic plan view of the principal part for demonstrating the usage example of the joining metal fittings for construction using the joining plate which concerns on embodiment of this invention.
In this figure, the metal fitting body 1 is not shown, but is fixed to the upper part of the corner true bundle 70 which is a main tree member, and the purlin junction plate 2b and the palm joint plate 2a are purlin members which are splint members, respectively. 71, a corner joint 72, a flat joint 73, and a wife joint 74. The bolts 25 and nuts are fixed to the intervening space at the ends. Furthermore, the splint member 2b and the palm joint plate 2a are engaged with the metal fitting body 1 so that the splint member is joined to the main wood member.

Then, it demonstrates with reference to sectional drawing of the usage example of the joining metal fitting for construction.
FIG. 7: has shown sectional drawing in the CC line of FIG. 6 which showed the usage example of the joining metal fitting for construction.
In the figure, the metal fitting body 1 is fixed to the corner true bundle 70 by the fixing means 3. Specifically, a shaft bolt 32 consisting of all screws is embedded in the corner true bundle 70 and fixed by the pin 31. The bracket body 1 is screwed onto the shaft member 30 a while being inserted into the shaft bolt hole 15 of the metal fitting body 1, and the nut 33 is fastened to the shaft bolt 32, so that the metal fitting body 1 is attached to the upper surface of the corner true bundle 70. Fixed. In order to prevent the nut 33 from loosening, a double nut is tightened.

  Here, it is preferable that a square tenon 41 is formed in the upper portion of the corner true bundle 70, and the thick plate member 4 having a tenon hole 42 fitted to the square tenon 41 is used on the bottom side of the metal fitting body 1 with a bolt 40. In this way, the metal fitting body 1 is joined to the main wood member at an angle determined by the mortise 42, so that the joining strength is improved and the metal fitting body 1 is prevented from turning around. can do.

The purlin 71 is joined to the metal fitting body 1 by the locking portion 22 of the purlin joining plate 2 b fixed to the end portion by the bolt 25 being engaged with the slit 12 of the metal fitting main body 1. However, strictly speaking, the joining plate 2b is movable upward.
For this reason, the joining plate 2b for purlins is good to set it as the structure which the front-end | tip part side by the side of the corner true bundle 70 contact | abuts the presser member 5, and if it does in this way, the joining plate 2b will not remove | deviate easily from the metal fitting body 1 ( It becomes impossible to move in the upward direction, and the locked state is maintained.), And the reliability of joining can be improved.

  The presser member 5 has a top surface shape that fits inside the cylindrical member 10 (an example of a shape that covers the upper opening of the metal fitting body), and the shaft bolt 32 passes through the center. A structure having a through hole is preferable. If it does in this way, the through hole of presser member 5 and washer 50 is inserted in shaft bolt 32, and the two nuts 51 are double-nut tightened so that it may not loosen, and the locked state of a joining plate is maintained easily. be able to.

The purlin 71 has a contact portion 71a protruding from the joining plate at the lower end of the tip, and the contact portion 71a is placed on the upper surface of the flange 11 of the metal fitting body 1 and supports the weight of the purlin 71. In this case, it is possible to disperse the external force acting on the slit 12 and the locking portion 22, and it is possible to prevent problems such as deformation of members around the slit 12 due to this external force.
Furthermore, for example, the position of the purlin 71 can be easily finely adjusted by cutting the contact portion 71a.
The same structure can be applied to other splint members, for example, the abutting portion 74a of the wife palm 74.

Further, the joint-joining plate 2a is fixed to the tip of the wife joint 74 by bolts 25 and nuts inserted into the bolt holes 21, 21, 21b, 21b.
Here, the jointing plate 2a for the palm joint is firmly fixed to the wife joint 74 because each bolt hole 21, 21, 21b, 21b can effectively exert substantially the same fixing force with respect to the wife joint 74. The
Further, the jointing plate 2a for the palm is fixed so that the upper surface of the upper oblique side 24 forms the same surface as the upper surface of the wife palm 74, and further, the lower surface of the lower oblique side 23 is located inside the lower surface of the wife palm 74, There is no protruding part, and it can join suitably.

On the other hand, as shown in FIG. 8, the joint plate 2 a for jointing is fixed to the tip of the corner joint 72 by bolts 25 and nuts inserted into the bolt holes 21, 21, 21 a, 21 a.
Here, the jointing plate 2a for the palm joint is firmly fixed to the corner joint 72 because each bolt hole 21, 21, 21a, 21a can effectively exert substantially the same fixing force with respect to the corner joint 72. The
Further, the joint plate 2a for the palm is fixed so that the lower surface of the lower oblique side 23 forms the same surface as the lower surface of the corner palm 72, and the upper surface of the upper oblique side 24 is located inside the upper surface of the corner joint 72. There is no protruding part, and it can join suitably.

  In this way, by using the construction fittings in the above-mentioned use examples, the joining work of the purlin 71, the corner joint 72, the flat joint 73, and the wife joint 74 can be easily performed. Even in the field, work efficiency and safety can be improved.

  When such a construction fitting is used, for example, the following unitized joining method can be adopted.

(1) Unit assembly process: In a good working environment such as a factory, the wooden members forming the roof are unitized in advance using the building joint fittings in the usage example, the beam receiving joint shown in FIG. Process.
Here, as an example of the unit, for example, using a fishing hook 78 and a wand 79, a roll joint 75 is joined to a flat joint 73 (see FIG. 9), or a corner joint 76 is joined to a corner joint 72. There is something that was done.

(2) Unit joining step: A step of assembling and joining the entire roof by joining the assembled unit to the corner bundle 70.
Here, the united corner joint 72, flat joint 73 and wife joint 74 are joined to the corner true bundle 70 by using various joint fittings such as the construction joint and beam receiving joint.

At this time, in the unitized flat joint 73 and wife joint 74, first, the joining plate fixed to the distal end is locked to the metal fitting body 1, and then the ladle 75 is joined to the corner true bundle 70 by the beam receiving fitting. To be joined to the corner true bundle 70.
Further, when assembling the unitized corner joint 72, the corner beam receiving and punching 77 is previously joined to the beam 75 by using a fire metal fitting (not shown) and a reinforcing plate. After that, the united corner joint 72 is first joined to the metal fitting body 1 with the joining plate fixed to the tip, and then the corner hole 76 is coupled to the corner beam receiver 77, Joined to the corner true bundle 70.

In this way, the united corner joint 72, flat joint 73, and wife joint 74 first receive the load at one end of each joint when the joining plate is locked to the metal fitting body 1. . As a result, the operator who has lifted this end is released from the lifting operation, and subsequently, this operator can perform the joining operation of the batting 75 and the corner boring 76, so 70 can be efficiently and easily joined. Further, other wooden members, for example, rafters, are sequentially assembled and joined.
In addition, the said beam receiving joining metal fitting is the technique which this inventor proposed in Japanese Patent Application No. 8-114161.

Moreover, the joining plate of this invention is applicable not only when the metal fitting main body is attached to the main tree member, but also when it is provided vertically such as a corner bundle.
Next, an embodiment in which the present invention is applied to an architectural fitting using a round bridge which is an axial bridge without using a main tree member will be described with reference to the drawings.

FIGS. 10A and 10B are schematic views for explaining the structure of the architectural fitting according to this embodiment. FIG. 10A is a side view and FIG. 10B is a top view of the main part.
In the figure, a construction joint metal fitting using a shaft bridge is a metal base body 1, a joint plate 2 a, and a bottomed cylindrical round bridge 201 attached to the metal part main body 1 so as to be connected to the lower part of the metal part main body 1. And an anchor block 202 attached to a flat joint 73 or the like which is a splint member, and a connection bolt 223 and a nut 224 which are connection members for connecting the round bridge 201 and the anchor block 202.

Here, the metal fitting body 1 is provided with a bolt hole 16 into which a fishing shaft bolt 216 is inserted and a shaft bolt hole 15 into which a bolt 34 for fixing the presser member 5 is inserted.
Although not shown, the bolt hole 16 is formed by shifting the position so that the fishing shaft bolt 216 does not contact the connecting bolt 223 in the round bridge 201. If it does in this way, when fixing connecting bolt 223 to round bridge 201, attachment work of fishing shaft bolt 216 and nut 224 can be performed easily.
The presser member 5 is attached using a bolt 34 and a nut 35 that penetrate the shaft bolt hole 15.

As shown in FIG. 11, the round bridge 201 has a structure in which a metal cylinder 214 such as a steel pipe is welded to a metal disk 212. The round bridge 201 is not limited to a welded structure. Moreover, it is not limited to a round shape, and may be a polygon.
Therefore, in this specification, these bridges may be collectively referred to as an axial bridge.
The circular plate 212 is shifted in position so that the fishing shaft bolt 216 does not abut against the connecting bolt 223, and the fishing shaft bolt hole 211 is perforated. In this way, the round bridge 201 and the connecting bolt 223 are connected to each other. When connecting, the nut 224 can be easily attached.

  Further, the circular plate 212 has a temporary fixing hole 215 into which a temporary fixing bolt (not shown) is inserted in the center. The round bridge 201 can be easily temporarily fixed to a temporary support which is a substitute for the main tree part material provided.

The cylinder 214 has a connecting bolt hole 213 into which the connecting bolt 223 is inserted in the direction in which the splint member is joined.
In addition, the drilling position and drilling location of the connecting bolt hole 213 are not limited to the above-described structure, and are naturally determined according to the joining direction of the splint members.

The round bridge 201 is connected to the metal fitting body 1 by a fishing shaft bolt 216, a pipe sleeve 217 into which the fishing shaft bolt 216 is inserted, and a nut 218 with the circular plate 212 facing down. The nut 218 is double nut-tightened to prevent the nut from loosening.
In this way, the round bridge 201 can be accurately connected to the position separated by the length of the pipe sleeve 217, and the structure can be reduced in weight. Further, since the gap between the pipe sleeves 217 is wide, the bolt 34 can be easily inserted into the shaft bolt hole 15 when the presser member 5 is fixed, and the presser member 5 can be fixed easily. it can.

  Although not shown in the drawings, the round bridge 201 is not limited to the above-described configuration in which the circular plate 212 is connected downward, and may be configured to be connected with the circular plate 212 up. When the round bridge 201 and the connecting bolt 223 are connected, the pipe sleeve 217 is positioned on the circular plate 212, and the work space is widened. Therefore, the fishing shaft bolt 216 and the nut 224 can be easily attached. be able to.

  The anchor block 202 includes a U-shaped plate 204, a block 205, and bolts 221 and nuts 222 that fix the block 205 to the U-shaped plate 204.

The block 205 is a rectangular parallelepiped block 205 in which a fixing bolt 252 is formed in a perpendicular direction without intersecting the connecting bolt hole 251 through which the connecting bolt 223 as a connecting member passes.
The block 205 is a technique proposed by the inventor in Japanese Patent Application No. 2000-153037.

  The U-shaped plate 204 has a structure including the block 205. As shown in FIG. 12, a rectangular flat plate-shaped base portion 241 in which a mounting hole 243 for a wooden member is formed, and protruding on both sides of the base portion 241. The side plate 242 is formed with a bolt hole 244 for fixing the block 205. If it does in this way, since a connection structure can be simplified, manufacturing cost can be reduced.

  Further, the side plate 242 is configured to sandwich the block 205 movably. In this way, when the connecting bolt 223 is attached, the block 205 into which the connecting bolt 223 is inserted is attached to the U-shaped plate 204 or attached in advance. Since the connecting bolt 223 is inserted into the block 205 and then the block 205 is rotated, the connecting bolt 223 can be easily inserted into the connecting bolt hole 213 of the round bridge 201. Can be done.

The anchor block 202 is attached to the flat palm 73 with a joint dowel 203, a pin 231 and a bolt 232.
The joint dowel 203 is a cylindrical member processed with an internal thread, and has pin holes into which two pins 231 are inserted.
This fixing means is a technique proposed by the present inventor in Japanese Patent Application No. 8-114161, and is not limited to the above configuration. For example, a male screw is processed instead of a female screw, and a bolt It is good also as a structure fixed using a nut instead of.
In addition, other structures and operations such as the joint-joining plate 2a are the same as those of the construction joint fitting in the embodiment.
