JPS6016185Y2 - Retainer for inside corner external wall corner - Google Patents

Description

[Detailed explanation of the idea] TECHNICAL FIELD The present invention relates to a retainer for an inside corner of an external wall.

At the large corner, a gap is created between the exterior wall panel forming one wall surface and the exterior wall panel forming the other wall surface, and an exterior wall corner having a cross-sectional shape is used to hide this gap.

However, in order to hold the outer wall corner of the lever in a state where the gap is closed, as shown in FIG. 3 into the corner stopper plate 4, and tighten the nut 5.
However, in this structure, the inside corner is narrow and there is no space, so the workability of tightening the nuts is poor, making it a time-consuming and difficult task.

In view of this, the present invention aims to provide a useful outer wall corner holder that can reliably hold the outer wall corner with a simple operation of tapping.

In the present invention, a notch is made at the base end of the plate-like body from the base end, and the two base-end pieces separated by the notch are bent in opposite directions to form an attachment part. One end of each of the pair of elastic plates is fixed, the central part of each elastic plate is formed into an outward trapezoid, and the other end of each elastic plate is attached to both sides of the proximal end of the plate. Either the ends of the elastic plates touch each other, or the other ends of the elastic plates touch each other on the extension of the tips of the plate-shaped bodies, or it is a holder for the inner corner outer wall corner with a detent projection formed on the outer surface of the central part of the elastic plate. be.

An example will be described below with reference to the drawings.

As shown in FIG. 2, the holder 10 for the inner corner of the outer wall corner includes a plate-shaped body 12 made of iron or the like having a mounting part 11 formed at the base end to be attached to the inner surface of the corner of the outer wall, and a plate-shaped body 12 on both sides of the plate-shaped body 12. One end is secured from an elastic plate 14.14 made of spring steel secured with a rivet 13 or the like.

In the illustrated example, the mounting portion 11 is formed by making a notch in the base end of the plate-shaped body 12 from the base end, and bending the base end pieces 11a and llb separated by the notch to the left and right. The mounting portion 11 is a C-shaped rail portion 16 fixed to the center of the inner surface of the inner corner outer wall corner 15 as shown in FIG.
It is installed by fitting into the

The elastic plate body 14.14 is formed into an outward trapezoid shape with a wide opposing interval between the central portions 14at 14a by bending a position near one end of the elastic plate body 14.14.
A, 14a are provided with a plurality of serrated detent projections 17 extending in the longitudinal direction.

In the illustrated example, the other end of the elastic plate 14.14 is bent in the same manner as the one end, and is brought into contact with the surface of the plate-like body 12.

In addition, the other side to which the holder 10 of this configuration is inserted (if the holder 10 is suitable for the conventional example shown in FIG. It is sufficient to open an insertion hole 19 that is slightly narrower than the spacing between the central portions 14a, 14a of the elastic plate.

In order to hold the inner corner outer wall corner 15 in a predetermined position using the holder 1 having the above structure, first attach the mounting part 11 of the holder to the rail part 16 on the inner surface of the inner corner outer wall corner 15 as shown in FIG. After installation, the tip of the holder is aligned with the insertion hole 19 of the outer wall panel connecting plate 18 shown in FIG.
This is done by hitting it from the outside with a mallet, etc. (see Figure 4 A).

When the holder 10 is hammered in this way, it is smoothly inserted into the insertion hole 19 due to the elastic deformation of the elastic plates 14.14, but once inserted, it is prevented from returning due to the elastic restoring force of the elastic plates 14.14. Since the protrusions 17 engage with the edges of the insertion hole 19, the inserted state is maintained without being removed.

Therefore, the outer wall corner 15 is also held in a state where the gap between the outer wall panels is closed without being removed.

In addition, in Fig. 4, 20 is an exterior wall panel, 21 is a wall frame, and 22
23 is a support plate for attaching the outer wall panel to the support fitting; and 24 is a presser plate for attaching the connecting plate 18 to the outer wall panel.

As explained above, in the present invention, a notch is made from the proximal end of the plate-like body, and the two proximal pieces separated by the notch are bent in opposite directions to form the attachment part.
One end of each of a pair of elastic plates is fixed to both sides of the tip of the plate-like body, the central part of each elastic plate is formed into an outward trapezoid, and the other end of each elastic plate is Either the proximal ends of the plate-like body are brought into contact with each other, or the other ends of the elastic plates are brought into contact with each other on the extension of the distal end of the plate-like body,
Since this is a holder for an inside corner of an outer wall, which has a detent projection formed on the outer surface of the central part of an elastic plate, the outer wall corner can be easily and reliably held.

In other words, since a pair of elastic plates are fixed to the tip of the plate-like body, spring steel having sufficient elasticity to insert and fix the holder into the insertion hole is used for the elastic plates. A plate-shaped body having sufficient rigidity can be used.

In addition, since a mounting part is formed at the base end of the plate-shaped body, this mounting part can be locked in the groove of the inside corner of the outside wall corner, making it easy to adjust the position along the longitudinal direction of the inside corner of the outside wall corner. can.

Moreover, this attachment part is formed by making a notch in the proximal end of the plate-shaped body from the base end and bending the two proximal pieces separated by this notch in opposite directions, so the dimensional accuracy of the attachment part is high. , it is easy to manufacture a device that fits perfectly into the groove of the rail section of the corner of the outside wall, and the holder does not rattle in the groove, and the mounting part is integrated with the plate-like body, so there is no risk of the mounting part coming off. It is suitable for mass production because it requires only cutting and bending.

Furthermore, one end of each of the pair of elastic plates is fixed to both sides of the distal end of the plate, and the other end of each elastic plate is in contact with both sides of the proximal end of the plate, or Since the other ends of the elastic plates are in contact with each other on the extension of the tip, when the holder is inserted into the corner insertion hole,
The pressing force applied to the elastic plate is supported by both ends of the elastic plate,
It applies a large elastic force and can be firmly attached, and the center portions of the pair of elastic plates are each formed into an outward trapezoid, and a detent protrusion is formed in this portion. Therefore, it has a locking effect over a wide range, can be adapted to various insertion depths of the holder, and can provide a sufficient elastic effect over the entire range.
