Description

[Detailed Description of the Invention] The present invention mainly relates to a tightening jig for joining the end portions of wall panels at right angles in an L-shape.

When constructing a wooden prefabricated house, when joining two wall panels together in an L-shape at right angles, if the panels warp,
A gap is likely to occur at the joint, making it difficult to securely connect the two.

The present invention provides a jig that joins panels while straightening them by pressure so that even panels with warpage can be easily joined at right angles in an L shape as described above. be.

For this reason, in the present invention, the operating rods having panel fixing plates at their tips are movably crossed with each other, and a support member equipped with a roller facing the crossing portion and a screw thread whose tips are loosely fitted into the support member. A panel tightening jig is proposed, which is characterized in that a tightening mechanism has a movable member screwed onto a rod, and the proximal end of the operating rod is connected to a support arm extending from the movable member. It can be effectively used especially when the ends of a wall panel whose ends are cut and shaped with a core material are joined in an L-shape at right angles, as shown in the drawings below. The gist of the present invention will be explained based on the illustrated usage example.

The drawing is a perspective view showing how the jig of the present invention is used.
1 is an operating rod having a panel fixing plate 2 fixed to its tip 1a, and the operating rod 1 is formed slightly longer than 1'.

Both are movably connected by a holding frame 3 in a state where they intersect with each other.

Reference numeral 4 denotes a tightening mechanism, in which a roller 6a is rotatably supported in the outer casing 5, fixes the supporting member 6, loosely fits a movable member 7, and has a tip end of a threaded rod 8 screwed into the movable member 7. is rotatably supported and fitted to the support member 6, and the other end is connected to a bundle 9 protruding outward from the outer casing 5, and the rotation of the bundle 9 brings the movable member 7 close to the support member 6. Or keep them separated.

A pair of support arms 7a project from the moving member 7 and are connected to the base end 1b of the aforementioned operating rod 1 via a linking member 11, respectively.

Reference numeral 12.12' is a wall panel, and in order to increase the strength when joining the corners, the corners are cut into a cross-sectional shape as shown in the figure using core materials 13a and 13b, and these are interlocked to form an angle that intersects at right angles. This is how you configure it.

Furthermore, the panel fixing plate 2 is provided with a locking hole 2a into which a screw is driven.

In addition, to explain the roller 6a in detail, although it is not clearly shown in the drawing, the roller 6a consists of two rollers, an upper and a lower roller, which face the operating rods 1 and 1', respectively, and are rotatably supported independently. ing.

To explain how the jig of the present invention having the above-mentioned configuration is used, in the corner C formed by the panels 12 and 12', the core material 1 of one panel 12' is
3a is on the same plane as the surface of the other panel 12 and exposes the panel corner itself, so screw the panel fixing plate 2 of the longer operating rod 1 onto the surface of the panel 12 beyond the core material 13a. A nail (not shown) is driven into the locking hole 2a and fixed, and the panel fixing plate 2 of the other short-eye operating lever 1' is fixed to the surface of the panel 12' close to the corner.

By doing this, the panel fixing plates 2 will be opposed to the core members 13a and 13b, respectively.

In this state, when the handle 9 is rotated clockwise in the drawing to separate the movable member 7 from the support member 6, the two rollers 6a are moved between the actuating rods 1 and 1' at the intersection of the actuating rods 1 and 1', respectively. At the same time, the operating rod 1.1' is brought into contact with each roller 6 via the supporting arm 7a and the connecting member 11.
Since the panel fixing plates 2, 2 are towed clockwise in the figure with a as a fulcrum, the panel fixing plates 2, 2 are pressed perpendicularly to each other and at the same time are pulled in the direction of the arrow.

Therefore, the T-shaped joint surface S formed by the core materials 13a and 13b is pressed together, and as a result, the panels 12, 12'
The warpage caused by the adhesive is forcibly corrected, and the adhesion is strengthened.

Under this condition, the necessary work, such as nailing, is carried out. After secure jointing, the panel fixing plate 2 is removed after loosening the handle 9, and if any screw nails remain, drive them into the panel. It performs the required surface finishing.

As mentioned above, by using the jig of the present invention, it is possible to perform the work of joining two panels at right angles in a single character shape very easily and reliably. It is suitable for joining wall panels in which core materials are arranged in molds, and the tightening method of the present invention has many practical advantages as a jig.

In the usage example, the panel fixing plate was fixed with screw nails, but instead of nailing, it is also possible to provide a large number of locking claws protruding from the fixing plate and drive them into the panel surface.
