Description

[Detailed description of the invention] This invention is used for fixing building panels, such as exterior wall panels and sashes, to the grooves with lips used in the wall frames of prefabricated houses. Regarding equipment.

Conventionally, to hold down building panels such as exterior wall panels and sash, a flat holding plate is placed against the edge of the building panel, and a fastener such as a bolt inserted through the holding plate is attached to the end of the building panel. This is done by screwing into the fixed part of the

Here, other fixing parts include a long corner stop plate with a rectangular cross section fixed to the wall frame at the large corner, and a long corner stop plate with a rectangular cross section fixed to the wall frame at the large corner. Connected plates etc. are used.

However, according to this conventional structure, no matter which one is used as the other fixing part, it is complicated because a hole for screwing the fastener must be made in advance at a predetermined position of the fixing part. On the other hand, there was an inconvenience in that it was not possible to hold building panels in place where there were no holes.

In addition, the tightening work is extremely troublesome in narrow corners, resulting in problems such as poor workability and delays in work.

In view of this, the present invention eliminates the need for other fixing parts such as corner retaining plates by utilizing channel steel with a lip used as a wall frame, and can be secured with one-touch operation even in narrow spaces. It is an object of the present invention to provide a new and useful building panel fixing device that is capable of holding down and fixing building panels with ease.

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 shows a building panel fixing device according to the present invention,
The upper end of the metal plate 1 is bent at a substantially right angle, and the bent portion 1a is
A holding plate 2 for fixing the building panel is rotatably attached with bolts 3.

A coil spring 4 is elastically mounted on the shaft of the bolt 3 between the holding plate 2 and the bent portion 1a, and the pressing force of the spring prevents the holding plate 2 from freely rotating.

Note that an elastic plastic plate may be used instead of the coil spring 4.

On the other hand, at both ends on the diagonal line on the outer surface of this plate 1,
Locking portions 9 and 10 are formed with their backs facing each other and opening in the vertical direction.

The locking portions 9 and 10 are formed by partially cutting and raising the plate 1 and bending the ends of the cut and raised pieces 7 and 8 in opposite directions, that is, in the vertical direction.

The locking portions 9 and 10 may be formed on a flat plate 5 separate from the plate 1, and the flat plate 5 may be fixed to the outer surface of the plate 1 with rivets 6.

The following procedure is used to press and fix building panels such as exterior wall panels using the fixing device having this configuration.

First, as shown in FIG. 2, the locking portions 9 and 10 formed on the outer surface of the plate body 1 of the fixing device are fitted into the grooves of the lipped channel steel 11 used in the wall frame assembly, and the locking portions 9 and 10 are The device is rotated by a predetermined angle in the direction of arrow P, and the lip portions 11 a and 11 b of channel steel are fitted and locked into the locking portions 9 and 10 .

In this case, in the illustrated example, protrusions 12 and 13 that protrude inward of the locking parts 9 and 10 are formed on the cut and raised pieces 7 and 8 that form the locking parts 9 and 10, so that the locking parts 9 and 10 are temporarily engaged. The lip portions 11a and 11b that are fitted and locked into the stop portions are maintained in a firm locking state so that they will not be accidentally removed.

Further, the positions where the cut and raised pieces 7 and 8 are formed are selected at both ends of the plate 1 on the right angle line, and the tip part 7a of the cut and raised pieces is selected.
, 8a are obliquely omitted, a relatively small rotation angle is required to attach the fixing device to the lip portions 11a, 11b.

After the fixing device has been secured to the channel steel in this way, the third
As shown in the figure or FIG. 4, wall frame 11 or 16
The ends of the building panel, such as the outer wall panel 14 or the sash 15 applied to it, are held between the presser plates 2 to fix the building panel.

After the building panel is applied to the side surface of the wall frames 11 to 16, the holding plate 2 is rotated so that the holding plate 2 can be locked to the end of the building panel.

Among the building panels, the exterior wall panel 14 is made by sandwiching a heat insulating material 20 such as polystyrene foam inside, and hardboards 21a and 21b bonded to both sides of the heat insulating material. A groove 22 is formed at the end.

In this groove 22, the end of the outer wall wall is connected to a protruding piece 23a.
.

In addition, when the building panel is a sash 15, a protruding piece 15a is formed on the side of the sash 15 to which the presser plate 2 can be engaged.

In addition, in FIG. 3 and FIG. 4, a wall frame assembly 1 to which a fixing device is attached to the end of a building panel such as a wall panel or a sash is shown.
Although it is held between the wall frame 16 adjacent to 1 and the presser plate 2, it is of course possible to hold it between the wall frame 11 to which the fixing device is attached and the presser plate 2. .

As explained above, the building panel fixing device according to the present invention has the upper end of the plate bent at a substantially right angle, and a retaining plate for fixing the building panel is rotatably attached to the bent portion with bolts. , a coil spring is elastically loaded on the shaft of the bolt between the holding plate and the bent part, and locking parts opening in the vertical direction facing away from each other are provided at both ends on a diagonal line on the outer surface of the plate. Because it is formed, it has the following effects.

(a) Since it can be attached to a channel steel with a lip, other fixing parts such as a corner stopper plate are not required as in the past.

Therefore, even in areas where there is no such fixing part, building panels can be held down and fixed if there is a channel steel with a lip.

(b) Since the fixing device is attached using the lip portion of the channel steel, there is no need to perform processing such as drilling holes in the channel steel.

(C) The fixing device itself has a simple and low-bulk structure with a holding plate attached to the plate via bolts, and it can be attached to the channel steel by rotating it, so it can be attached to large corners. When a door is installed near a corner or a large corner, the fixing device can be attached to the groove or steel with one touch without any tedious work even in a narrow space such as between the inside corner and the door.

(d) Since the holding plate is pre-attached to the bent portion of the upper end of the plate, holding down building panels, etc. can be done simply by rotating the holding plate. Excellent workability.
