Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a plate-shaped outer surface of a rectangular hollow member in a building, as in the case where an outer wall panel is fixed to a pillar having a C-shaped cross section in a prefabricated house. The present invention relates to a metal fitting for attaching a member.

[Conventional technology]

The outer wall panel in a prefabricated house generally has a front plate 1b and a back plate 1c fixed to both front and back surfaces of a frame body composed of side frames 1a having a U-shaped cross section as shown in FIG. At the same time, it has a structure in which a heat insulating material 1d is filled between the front surface plate 1b and the rear surface plate 1c, and in order to attach the outer wall panel 1 to the outer surface of the square hollow member pillar 2 having a C-shaped cross section or the like, Conventionally, the metal fitting 3 as shown in FIGS. 6 to 8 has been used.

That is, the conventional metal fitting 3 includes a bolt 4 whose one end 4a is bent in an L shape, and a nut 5 which is screwed into the bolt 4.
Holding plate 6 with a substantially L-shaped cross-section that is rotatably caulked and fixed
And the nut 5 is rotated to widen the gap between the one end 4a of the bolt 4 and the pressing plate 6, and then the bolt 4
One end 4a of each of the side plates of the column 2 is inserted into a hole 7 formed in one side plate 2a of the side wall to which the outer wall panel 1 is closely attached, and then the pressing plate 6 is attached to the side frame 1a at its tip. While holding the posture so that the bent portion 6a at the base end is in contact with the outer surface of the support column 1, by tightening the nut 5, the one end plate 4a of the support column 2 and the outer wall of the support column 2 by the one end portion 4a of the bolt 4 and the pressing plate 6. The panel frame 1 and the side frame 1a and the back plate 1c are integrally sandwiched.

[Problems to be solved by the device]

However, when the bolt 4 is inserted into the hole 7 like the conventional metal fitting 3, when the nut 5 is tightened,
A moment around the axis of the bolt 4 is generated in the pressing plate 6,
Since the pressing plate 6 is rotated together with the rotation operation of the nut 5, when tightening the nut 5, the operator must
Since the pressing plate 6 must be strongly pressed against the support column 2 to maintain its posture, it takes a lot of time to install the outer wall panel 1, and the one end 4a of the bolt 4 is gravitational. Since the one end portion 4a of the bolt 4 is located at a position apart from the attachment points of the side frame 1a and the back plate 1c of the outer wall panel 1, the pressing force of the pressing plate 6 against the side frame 1a is weak, There is a problem that the mounting strength of the outer wall panel 1 is low.

Further, in order to rotatably caulkly fix the nut 5 to the pressing plate 6, a high level of processing technology is required. Therefore, the nut 5 cannot rotate with respect to the pressing plate 6, or conversely falls off from the pressing plate 6. There was also a problem in that the product defect rate, such as slaps, was high.

It is an object of the present invention to provide a metal fitting that allows a plate-shaped member to be attached to the outer surface of a rectangular hollow member without causing these problems.

[Means for Solving the Problems]

To achieve this object, in the present invention, a bolt inserted into a bolt hole formed in a base end portion of one of the two sandwiching plates and a bolt hole formed in the base end portion of the other sandwiching plate is screwed. A female screw hole to be fitted is bored, and an engaging portion which fits and engages with a hole bored in one side plate of the rectangular hollow member in the building is formed at the tip of the one holding plate, while the other holding plate is provided. At the tip, a pressing portion that contacts a plate-shaped member that is in close contact with the outer surface of the one side plate of the square hollow member is formed, and the two sandwiching bodies are mutually sandwiched between the one sandwiching plate and the other sandwiching plate. An elastic body that urges in a separating direction is inserted, and a locking piece that comes into contact with the other sandwiching plate to prevent rotation of the other sandwiching plate is inserted into the one sandwiching plate or the other sandwiching plate. It is configured to be provided.

[Function and effect of device]

In this configuration, in order to attach the plate member to the outer surface of the one side plate of the square hollow member, loosen the bolt to widen the gap between the two holding plates, and then set the engaging portion of one holding plate to the square hollow member. It suffices to insert the bolt into the hole of one side plate of the member and then screw in the bolt, and the two clamping plates are attracted to each other by screwing the bolt, so that the one side plate and the plate-shaped member in the rectangular hollow member can clamp one side The plate-shaped member is attached to the rectangular hollow member by being sandwiched by the engaging portion of the plate and the pressing portion of the other sandwiching plate.

In this case, by inserting an elastic body that urges the two holding plates in a direction away from each other between the two holding plates, it is possible to maintain a state in which the distance between the two holding plates is widened.
The work of inserting the engaging portion of the one holding plate into the hole of the one side plate of the rectangular hollow member can be extremely easily performed.

Further, both sandwiching plates are not those which are pressed and fixed to the rectangular hollow member with bolts, but the base end portions of both sandwiching plates are fastened together with bolts, and one sandwiching plate is screwed in by bolts. Since it does not rotate together, one holding plate can hold its posture by holding it lightly by hand, and the other holding plate rotates with respect to one holding plate. Since the other holding plate is locked improperly and does not rotate together with the screwing of the bolt, the other holding plate does not need to be held by an operator. When mounting the plate-shaped member, it is possible to hold the metal fitting in a predetermined posture by simply holding one of the holding plates lightly.

Furthermore, since the other sandwiching plate is not rotatable with respect to the one sandwiching plate, the engaging portion of the one sandwiching plate and the pressing portion of the other sandwiching plate have a plate shape with the one side plate of the rectangular hollow member. Since it is located on the opposite side of the member, the force due to the screwing of the bolt is concentrated on the pressing portion of the other holding plate, and the plate member can be pressed with a strong force.

Therefore, according to the present invention, since the bolt can be screwed in with the metal fitting lightly held, it is possible to reduce the load required to maintain the attitude of the metal fitting and improve the efficiency of the work of attaching the plate member. In addition, since the plate-shaped member can be pressed with a strong force, the attachment strength of the plate-shaped member can be significantly improved.

In addition, as means for tightening both holding plates, female screw holes are only bored in one holding plate and bolt holes are bored in the other holding plate, respectively, as in the case of rotatably caulking and fixing the nut. Since no advanced processing technology is required, it is possible to reduce the defective rate of products.

〔Example〕

Next, an embodiment in which the present invention is applied to a mounting bracket for an outer wall panel 1 in a prefabricated house similar to the above,
Referring to the drawings (FIGS. 1 to 5), reference numeral 10 in the drawings indicates a metal fitting according to the present invention, and the metal fitting 10 is a pillar 2
The one holding plate 11 with respect to the one side plate 2a, and the other holding plate 12 stacked on the one holding plate 11 are provided, and a bolt 13 having a hexagonal hole or the like is fitted to the base end of the other holding plate 12 described above. A bolt hole 14 is provided at the base end of one holding plate 11 so that the bolt 13
While the female screw holes 15 into which the two are screwed are respectively formed, a portion of the shaft portion of the bolt 13 between the both holding plates 11 and 12 is urged in a direction in which the both holding plates 11 and 12 are separated from each other. As an example of the elastic body, an elastic collar body 16 such as soft rubber is fitted.

An engaging portion 11 that fits and engages with a hole 7 formed in the one side plate 2a of the column 2 at the tip of the one sandwiching plate 11.
A is formed in a stepped shape, and the one holding plate 1
At the side edge of 1 in the vicinity of the female screw hole 15, the leg pieces 11b are formed by bending in the opposite direction to the other sandwiching plate 12, and further, the upper end of the base end of the one sandwiching plate 11 is formed. A locking piece 11c for preventing the other holding plate 12 from rotating in the screw-in rotation direction of the bolt 13 is provided at the side portion.
It is bent and formed in the direction of the other holding plate 12.

Then, at the tip of the other holding plate 12, a pressing portion 12a bent in a dogleg shape is formed, while the base end of the other holding plate 12 is bent in the direction of the one holding plate 11, and a bolt is formed. 13
When the screw is screwed in, the tip end surface of the bent piece 12b is configured to come into contact with the surface of the one holding plate 11, and
The one holding plate 11 is provided at the upper end of the bent piece 12b.
Forming a notch 12c that engages with the locking piece 11c in
The other holding plate 12 is configured to rotate in the screw return rotation direction of the bolt 13 but not to rotate in the screw rotation direction of the bolt 13.

The notch 12c in the other holding plate 12 is not always necessary, and the side surface of the other holding plate 12 may be brought into direct contact with the locking portion 11c, and FIG. As shown by the alternate long and short dash line, the other holding plate 12 is provided with a locking piece 12e at the base end of the other holding plate 12, and the locking piece 12e is brought into contact with the side surface of the one holding plate 11. However, it may be arranged such that it cannot be rotated in the screwing rotation direction of the bolt 13,
Further, the holding plates 11 and 12 may be provided with the locking pieces 11c and 12e, respectively.

In the above configuration, in order to fix the outer wall panel 1 to the support column 2, one holding plate 11 is rotated to a posture substantially orthogonal to the other holding plate 12, and the engaging portion 11a of the one holding plate 11 is rotated. Is inserted horizontally into the hole 7 of the side plate 1a of the column 1,
Next, the other holding plate 12 is rotated horizontally as shown by the arrow A, and then the bolt 13 may be screwed in. The bent piece 12b of the other holding plate 12 is attached to the surface of the one holding plate 11. By abutting, by screwing in the bolt 13,
Since the gap between the engaging portion 11a of the one sandwiching plate 11 and the pressing portion 12a of the other sandwiching plate 12 is narrowed, the side frame 1a and the back plate 1c of the outer wall panel 1 are provided on both sandwiching plates 11 and 12. And is fixed to one side plate 2a of the column 2.

In this case, since the elastic collar body 16 is fitted on the bolt 13, it is possible to maintain the state in which the distance between the two sandwiching plates 11 and 12 is widened, so that the engaging portion 11a of one sandwiching plate 11 is inserted into the hole 7. The insertion work can be done easily.

In addition, the bolt 13 merely fastens the base end portions of the two holding plates 11 and 12 together, and one holding plate 11 does not rotate together with the bolt 13 when the bolt 13 is screwed in. The holding plate 11 can hold its posture only by holding it lightly, and the other holding plate 12 rotates in the screwing rotation direction of the bolt 13 in a posture extending in the same direction as the one holding plate 12. Since it is impossible, the other holding plate
Since it is not necessary to hold the posture by holding 12 by hand, it is possible to reduce the load required to maintain the posture of the metal fitting 10 and improve the work efficiency of the work of attaching the outer wall panel 1.

Since the holding plates 11 and 12 are held in the postures in which they extend in the same direction, the side frame 1a of the outer wall panel 1 can be pressed by the other holding plate 12 with a strong force. The mounting strength of the panel 1 can also be improved.

In this case, when the foot pieces 11b are provided on both side edges of the one holding plate 11 as in the embodiment, the foot pieces 11b come into contact with the outer surface of the other side plate 2b adjacent to the one side plate 2a of the column 2. Accordingly, since the one sandwiching plate 11 can be positioned more reliably and quickly, there is an advantage that the work of attaching the outer wall panel 1 can be performed more easily. The other holding plate 12 may be configured so as not to rotate in any direction around the axis of the bolt 12, but as in the embodiment, the bolt 13
If it is configured to rotate only in the screw return rotation direction of,
Since the other holding plate 12 can be brought into a posture intersecting with the one holding plate 11, the engaging portion 11a of the one holding plate 11 is inserted into the hole 7 without the screw 13 being largely unscrewed. It has an advantage that the work can be easily performed.

Note that the outer wall panel 1 may be finely adjusted in its mounting position after it is once mounted. In this case, in the prior art shown in FIGS. From the gap, a special spanner made of metal plate 8
Although the nut 5 is rotated by the wrench 8 by inserting, the wrench 8 can be rotated only slightly by this method, so when loosening or tightening the nut 5, The operation of rotating the wrench 8 slightly and then fitting it back into the nut 5 must be repeated, which makes the rotation of the nut 5 awkward, and
In order to prevent the pressing plate 6 from rotating when the nut 5 is loosened, it is necessary to hold the posture of the pressing plate 6 by inserting a finger through the gap, so that the mounting position of the outer wall panel 1 is finely adjusted. It took a lot of work.

On the other hand, if it is configured as in the above-described embodiment, as shown in FIG. 5, the bolts 13 have the outer wall panel 1 adjacent to each other.
While it can be easily rotated with a normal hex wrench 17 or socket wrench inserted from the gap between the two, the foot piece 11b of one holding plate 11 is inserted into the gap between the adjacent columns 1. By holding the bolts 13, it is possible to maintain the posture of the one holding plate 11 even when the bolt 13 is loosened, and the other holding plate 12 is also held in the posture of extending in the same direction as the one holding plate 11 Since 13 is held in a predetermined posture even if the operator does not press it by hand, the work of finely adjusting the mounting position after once mounting the outer wall panel 1 is also possible.
Very easy to do.

It should be noted that as a means for urging the two holding plates away from each other, other means such as fitting a coil spring to a bolt may be adopted, and one holding plate is provided with a female screw. As a means, a nut may be welded instead of tapping a female screw on one holding plate as in the embodiment.
