[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a binding tool suitable for joining a roof and a wall and capable of improving workability and safety.

"Prior Art" Conventionally, as an example of a structure in which a roof having a structure in which a back plate of the roof is supported by rafters is joined to an upper end portion of a wall, a structure in which a binding fitting 1 shown in Fig. 6 is joined is known. ing.

The binding metal fitting 1 used in this joining structure has a structure in which two boards 3 and 4 in which through holes 2 for nailing are formed are vertically integrated through a bent portion 5. , 4 are 90 to each other
° Formed to face different directions. The roof 6 joined by the binding metal fitting 1 having the above-mentioned structure is formed into a panel shape in which the back plate 7 is supported by a plurality of rafters 8, and the walls 9 are vertically and horizontally assembled in a lattice shape. It has a panel structure in which face plates 11 and 11 are attached to both surfaces of a core material 10. A connecting girder 12 having a triangular cross-section is attached to the upper end of the wall 9 in order to match the inclination of the roof 6.

Then, one board 4 of the binding metal 1 is brought into close contact with the upper surface of the wall 9 and the other board 3 is brought into close contact with the side surface of the rafter 8, and the rafter 8 is provided through the through holes 2 of the boards 3 and 4. Core material 1
The roof 6 and the wall 9 are joined by nailing or screwing to each of 0.

[Problems to be solved by the invention] In order to perform the work of joining the roof 6 and the wall 9 using the binding metal fitting 1, after installing the panel-shaped roof 6 on the upper end of the wall 9,
The operator approaches the joint while supporting the binding metal fitting 1,
It is necessary to perform nailing or screwing work while supporting the binding member 1. However, the lower side of the joint portion between the roof 6 and the wall 9 is a place where only a small working space can be taken, so that there is a problem that a stable working posture is difficult, and nailing work becomes extremely complicated and a cramped working posture. Therefore, there is a problem that work safety is low.

In addition, the deformation of the wood constituting the roof 6 and the wall 9, or
If dimensional errors occur during the production of these members, when the roof 6 is installed on the wall 9, a gap may be created between the upper end of the wall 9 and the rafters 8 of the roof 6, In the case of joining using the conventional binding metal fitting 1, there is a problem that satisfactory joining cannot be achieved if the above-mentioned gap is formed.

The present invention has been made in view of the above circumstances, and in the joining work of the roof and the wall, it is not necessary to perform nailing or screwing work in a cramped posture, and the joining can be performed by a simple operation, and the dimensional error of the roof and the wall. An object of the present invention is to provide a binding tool for a roof and a wall that does not cause a joint failure due to the above and can be easily disassembled after construction.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a locking board fixed to a side portion of a roof rafter joined to an upper end of a wall, and a locking board protruding from the locking board. And an upper end surface of the wall, which includes a supporting arm and a connecting arm that is supported by the supporting board so as to be tilted up and down with respect to the locking board and protrudes to the outside of the locking board. A fixed base plate attached to the fixed base plate, a locking piece extending at a right angle or an inclination with respect to the fixed base plate, and a slit formed in the locking piece in a notch shape and capable of inserting the connecting arm. And a threaded portion is formed on the connecting arm, and a nut is screwed into the threaded portion.

[Operation] By fixing the locking tool to the rafters of the roof and fixing the fixing tool to the upper end of the wall, rotate the connecting arm when installing and joining the rafters of the roof to the upper end of the wall. Then, the roof and the wall are easily joined by inserting them into the slits of the locking plate of the fixture and tightening the nuts, which eliminates the need for cramping nails and the like at the joints. Also, by inserting the connecting arm into the slit of the locking plate and tightening the nut, the roof rafter can be pressed against the upper end of the wall, so there is some deformation of the roof or wall and the rafter and the upper end of the wall. Even if a gap is formed between the two parts, they can be sufficiently brought into close contact with each other to be joined. Further, when the building is demolished, the joint between the roof and the wall is released by loosening the nut and rotating the connecting arm to remove the connecting arm from the locking plate.

[Embodiment] FIGS. 1 to 3 show an embodiment of the present invention. The fastener of this embodiment is a fixing member 15 fixed to the wall side.
And a locking tool 16 fixed to the roof side.
Since the roof or wall joined in the binding tool of this embodiment has the same structure as the panel-shaped roof 6 or wall 9 described in the conventional example, the same parts are designated by the same reference numerals. The description is omitted.

The fixture 15 includes a flat plate-shaped fixed substrate 17 shown in FIG.
A locking plate 18 extending on the fixed substrate 17 at a predetermined angle with respect to the fixed substrate 17, and a reinforcing plate 19 connecting one side of the fixed substrate 17 with one side of the locking plate 18. It is configured. The inclination angle of the locking plate 18 with respect to the fixed substrate 17,
The roof 6 is formed to have the same inclination angle.
Further, in the locking plate 18, a notch-shaped slit 20 is formed toward the reinforcing plate 19 side at the center of the side portion opposite to the side connected to the reinforcing plate 19. In addition, through holes 21 for nailing or screwing are formed at four corners of the fixed substrate 17.

As shown in FIG. 1, the locking member 16 is composed of a flat plate-shaped locking substrate 22 and bearing-shaped supporting portions 23, 23 projecting from the lower side of the locking substrate 22 so as to be spaced apart from each other. It is composed of a connecting arm 24 which is supported so as to be able to tilt up and down, and through holes 25 for nailing or screwing are formed at four corners of the locking base plate 22. Further, a protrusion 26 is formed on one side of the lower end of the locking substrate 22 so as to extend the locking substrate 22, and a locking piece 27 is formed on the protrusion 26 at a right angle to the locking substrate 22. Has been done.

The connecting arm 24 is a T-shaped one including a rod-shaped base portion 28 and a rod-shaped arm portion 29 vertically connected to the central portion of the base portion 28, and both ends of the base portion 28 are supported by the support portions 23, 23. An arm portion 29 is rotatably supported and is provided so as to be able to move up and down with respect to the locking base plate 22. The arm portion 29 is formed to be slightly shorter than the long side portion of the rectangular locking substrate 22, and the arm portion 29 is located below the locking substrate 22 when the arm portion 29 is tilted to the lower side of the locking substrate 22. It is designed to stick out. Further, a screw portion 30 is formed on the arm portion 29, and a nut 31 is screwed into the screw portion 30.

Next, a case where the roof 6 and the wall 9 are joined by using the fixing tool 15 and the locking tool 16 having the above-described configuration will be described.

Before building the panel-shaped roof 6 in building a building, the wall 9 is set up in advance at a building site, and the roof 6 is installed on the set up wall 9 to perform the joining work.

Further, since the position of the joint between the roof 6 and the wall 9 is determined in advance in the design stage, the fixture 15 is previously nailed to the lower side of the portion where the rafter 8 of the roof 6 is in contact with the wall 9. The locking base plate 22 of the locking tool 16 is fixed to the side surface portion of the rafter 8 that abuts the wall 9 while being fixed by fixing or screwing.

When fixing the locking tool 16 to the side surface of the rafter 8, as shown in FIG. 1, the bottom of the locking base plate 22 is set along the bottom of the rafter 8 so that the arm 29 can be tilted up and down. It is necessary to fix the locking piece 27 so that the locking piece 27 projects from the lower surface of the rafter 8. Also, the rafter 8 is a locking tool
When 16 is fixed, as shown in FIG. 3, the arm 29 is rotated to the upper side of the locking board 22 so as to follow the locking board 22, and the nut 31 is positioned on the tip side of the arm 29. Keep it.

Furthermore, when fixing the fixture 15 to the joint girder 12 at the upper end of the wall 9, the fixture 15 is fixed so that the upper surface of the locking plate 18 and the inclined surface of the upper face of the joint girder 12 are flush with each other. .

On the other hand, the fixtures 15 and the fixtures 16 are fixed respectively in the case of an industrialized house of a type in which the roof 6 and the wall 9 are assembled in advance in a factory or the like and are carried to a construction site to be assembled. It can be installed at the stage. First,
The fixture 15 may be attached after the wall 9 is built at the building site and before the joint work with the roof 6 is performed, or before the wall 9 is built at the site. Well, in some cases it may be pre-positioned at the factory. Also, the locking tool
The mounting of the 16 may be done before the work of joining the roof 6 to the wall 9 or, in some cases, at the factory.

When the roof 6 to which the locking tool 16 is fixed as described above is installed at the prescribed position of the upper end of the wall 9, the locking side 27 of the locking base plate 22 abuts on the end of the locking plate 18, so that the roof 6 can be easily positioned. After the roof 6 is positioned, the arm 29 is rotated downward from the state shown in FIG. 3 to move the slit 20 of the locking plate 18 as shown by the chain double-dashed line in FIG.
To insert. In this state, since the nut 31 has moved over the slit 20 and below the locking plate 18, the nut 31 is rotated and the locking plate 18 is tightened to press and join the roof 6 to the coupling girder 12. be able to.

The above operation completes the joining of the roof 6 and the wall 9. Since the joints between the roof 6 and the wall 9 are located at a plurality of locations in the building, the joints between the roof 6 and the walls 9 are completed by performing the same operation as described above for each of the fasteners 16 attached to the plurality of locations. To do.

If the roof 6 and the wall 9 are joined as described above, nailing becomes unnecessary and the nut 31 is rotated as compared with the conventional work where nailing and screwing are performed in a narrow place. Since only the operation of tightening the locking plate 18 by means of the above is performed, there is an effect that the joining work can be simplified. Further, when the building is dismantled as necessary, the joint can be released only by loosening the nut 31 and removing the arm portion 29 from the slit 20, so that the dismantling can be easily performed.

By the way, conventionally, when joining the roof 6 and the wall 9, the roof 6 is fixed by nailing so as to reach the wall 9 from the upper side of the rafter 8, but such a construction method is used. If this is done, there is a problem that finishing work such as waterproofing work on the roof top surface cannot be completed before nailing is completed.

In this respect, if the joining work is carried out using the binding device of the present invention, the joining work of the roof 6 and the finishing work of the upper surface side of the roof 6 can be carried out separately, so that the finishing work of the roof 6 can be completed in advance. It can also be carried out, and has the effect of shortening the construction period.

4 and 5 show a second embodiment of the present invention,
The same components as those of the first embodiment described above are designated by the same reference numerals and the description thereof will be omitted.

The binding tool of this embodiment is suitable for joining a flat roof to a wall, and is composed of a locking tool 16 and a fixing tool 31.

The lock 16 has the same structure as the lock 16 of the first embodiment described above.

The fixture 31 has the same structure as the fixture 15 of the first embodiment, and includes a fixed substrate 32, a locking plate 33, and a reinforcing plate 34. Are different in that they extend at a right angle. In addition, through holes 36 are formed at the four corners of the fixed substrate 32, and a notch-shaped slit 37 is formed in the locking plate 33.
Are formed.

The locking tool 16 and the fixing tool 31 having the above-described structure are similar to the locking tool 16 and the fixing tool 15 of the first embodiment described above, and the upper end surface of the wall 9 and the rafters 8 of the roof 6. Used for joining the rafters 8 and the wall 9 by fixing them to the side surfaces of the.

Since it is the flat roof that is joined by the binding device of this embodiment, the connecting girders 12 provided at the upper end portion of the wall 9 in the case of the above-described first embodiment are omitted, and are directly attached to the upper end portion of the wall 9. ,
The rafters 8 on the roof are joined together.

Roof rafters 8 using the locks 16 and fixtures 31 of this embodiment
If the and the wall 9 are joined, the same effect as in the case of the first embodiment can be obtained.

In addition, in the said Example, although the example which provided the binding tool only on one surface side of the rafter 8 was demonstrated, it is needless to say that the binding tool may be provided on both surface sides of the rafter 8.

[Advantage of the Invention] As described above, the present invention fixes the locking member to the roof rafter and the fixing device to the upper end of the wall, and installs the roof rafter on the upper end of the wall. Then, by rotating the connecting arm to insert the connecting arm into the slit of the locking plate and tightening the nut on the locking plate, the roof and the wall can be easily joined. Moreover, since the locking device and the fixing device can be fixed to the rafter or the wall in advance before the joining work, nailing and screwing work can be performed in the narrow work space where the roof is installed on the wall. There is no need to perform it, workability is improved, and work safety is also improved. Further, when it becomes necessary to dismantle the building, the joint between the roof and the wall is released by rotating the nut and removing the connecting arm from the locking plate, so that the dismantling work of the building can be easily performed.
