Description

[Detailed Description of the Invention] This invention relates to a corner holder of a panel fastener used when constructing a floor or wall by pulling together a plurality of panels in a prefabricated building.

Conventionally, in the prefabricated method of building buildings such as houses by combining multiple panels, corner holders are secured to both ends of multiple panels, and the panels are tightened by drawing these corner holders toward each other. panel fasteners were used to assemble floors and walls.

However, in the above-mentioned fasteners, for example,
When placing and tightening the second-floor floor panel on the first-floor wall panel, the edge of the second-floor floor panel is placed in the notch formed inside the upper part of the first-floor wall panel, creating a stepped shape. If it is installed, the locking part of the corner holder is formed into a simple flat surface, so although it is possible to pull the floor panel on the second floor, it is not possible to pull the wall panel on the first floor at the same time. Therefore, in cases where the wall panels on the first floor are warped outward, the wall panels on the first floor do not adhere to the floor panels on the second floor, creating a gap that makes it difficult to construct a building properly. The drawback was that it couldn't be done.

This idea was developed with the above points in mind, and its purpose is to be able to draw multiple panels together on the same plane, and to reduce the number of places that can be attached adjacent to these panels. Panel tightening that allows panels to be pulled in the same direction at the same time, and also allows the panels to be brought into close contact with the adjacent panels without creating gaps, allowing for successful construction of the building. An object of the present invention is to provide a corner holder for a tool.

Hereinafter, one embodiment of this invention will be described in detail based on the drawings.

1 to 3 are diagrams showing the construction state of a building constructed by combining a large number of panels, and in these figures, reference numeral 1 indicates a panel fastener.

This panel fastener 1 includes a pair of corner holders 2, 2 that are locked to corresponding surfaces at both ends of a plurality of panels combined, and a pulling tool 3 that draws the corner holders 2.2 together.
It is composed of.

That is, the corner holder 2 is attached to each end surface 4a, 5 of the floor panel 4 on the second floor and the wall panel 5 on the first floor, for example.
A locking portion 6 that presses against and locks the locking portion 6 and an arm portion 7 that pulls the locking portion 6 are integrally formed of a highly rigid metal in a rectangular shape.

Moreover, the locking portion 6 is connected to the end surface 4a of the panels 4, 5.
, 5a is formed in a stepped portion 8 having two steps.

For example, as shown in FIG.
This corresponds to the difference in level from the end surface 5a of the wall panel 5 on the floor.

That is, this step is created by cutting out half of the inside of the upper part of the wall panel 5, and the floor panel 4 of the second floor is placed in this cut-out part, and the almost upper half of this panel 4 is cut upward. It is constructed by protruding.

Therefore, in the stepped portion 8, the first stepped surface 8a that contacts the end surface 4a of the floor panel 4 is provided on the base side of the locking portion 6, and the first stepped surface 8a that contacts the upper outer surface 5a of the wall panel 5 is provided. Two stepped surfaces 8b are provided on the distal end side of the locking portion 6.

In this case, the step between the step surfaces 8a and 8b is the thickness 5b of the uncut portion of the upper part of the wall panel 5.
is set slightly smaller than .

This is to pull together the floor panels 4 and the wall panels 5 on the second floor at the same time.

Further, each panel 4, 5 is provided on each stepped surface 8a, 8b.
There are protruding claws 9, 9 that sink into the end surfaces 4a, 5a and prevent the stepped surfaces 8a, 8b from shifting from the end surfaces 4a, 5a.

Further, a hooking ring 10, 10 is attached to each arm portion 7.7 of each of the corner holders 2, 2, and a wire 12. 12 are attached respectively.

Furthermore, the pulling tool 3 that pulls the corner holders 2, 2 together has a pulley 13 hooked to one of the hooks 11.11 of the wire 12.12, and a pulley 13 hooked to the other hook 11 via the pulley 13. wire 14 and a handle 15 for pulling this wire 14. When the handle 15 is swung, the end of the wire 14 is pulled, pulling the hook 11 on which the wire 14 is hooked via the pulley 13, and also the hook 11 on which the pulley 13 is hooked. At the same time, the corner holders 2, 2 are drawn together, thereby drawing the pair of corner holders 2, 2 together.

Next, a case will be described in which, for example, floor panels 4 on the second floor are constructed using the panel fastener 1 configured as described above.

First, the floor panels 4 on the second floor are arranged in the same plane, with the notches formed in the upper part of the wall panel 5 being placed in the same direction.

Then, at the place where the floor panel 4 and the wall panel 5 come into contact,
A step as shown in FIG. 3 is constructed.

Thereafter, corner holders 2, 2 are arranged corresponding to this step.

In this case, the corner holders 2, 2 are connected to the floor panels 4...
are arranged at both ends in the arrangement direction and in corresponding locations.

Furthermore, after this, each corner holder 2, 2 is attached to each panel 4, 5.
Press it to the side.

Then, the claws 9, 9 protruding from the stepped portion 8 are wedged into the end surface 4a of the floor panel 4 and the upper outer end surface 5a of the wall panel 5, respectively, and the respective stepped surfaces 8a of the stepped portion 8.

8b abuts on each of the end surfaces 4a, 5a.

That is, the first stepped surface 8a of the stepped portion 8 contacts the end surface 4a of the floor panel 4, and the second stepped surface 8b contacts the end surface 5a of the wall panel 5, respectively.

When the corner holders 2, 2 are arranged in this manner, the corner holders 2, 2 are fixed by the winter melons 9, 9 without any undesirable movement.

Thereafter, by swinging the handle 15 of the pulling tool 3 and pulling the wire 14, the pulley 13, hook 11. .

11 and the corner holder 2 via the wires 12, 12,
Pull the two together.

Then, the first stepped surfaces 8a, 8 of the corner holders 2, 2
The floor panels 4 are drawn together by a and come into close contact with each other, and the wall panels 5,
5 are drawn toward the floor panel 4 side and come into close contact with each other.

As a result, the floor panel 4 and the wall panel 5 can be closely fixed without creating a gap between them.

However, since this is temporary fixing, each panel 4.
. . , 5 . . . by driving screw nails 16 . . . into the joints of the panels 4 .

In this case, a joist support 17 is placed especially on the inner side where the floor panel 4 and the wall panel 5 intersect, and screw nails 16 and 16 are driven into the joist support 17 vertically and horizontally, so that the floor panel 4 and the wall panel 5 intersect with each other. The above wall panel 5 is firmly fixed.

When each panel 4..., 5... is firmly fixed in this way, all you have to do is operate the handle 15 of the pulling tool 3 to loosen the tightening and remove each corner holder 2, 2. .

In the above embodiment, the case where the second floor floor panels 4... are attached to the wall panels 5 has been described, but in the panel fastener 1 described above, the first floor floor panels 18...
It can also be used when arranging on the foundation 19.

As explained above, according to the corner holder of the panel fastener according to this invention, the locking part of the corner holder is attached to the end of a plurality of panels, and the panel is attached adjacent to this end. Since the structure is such that the end of the mounting panel intersects with the end of the mounting panel in a step-like manner and is formed in a two-step step corresponding to the mounting point, for example, it can be placed in a notch formed in the upper part of the wall panel to form a step-like structure. It is possible to draw and tighten multiple floor panels to be installed in the same plane, and
The stepped portion of the corner holder allows the notch in the wall panel to be pulled toward the floor panel at the same time as tightening the floor panel, so even if the wall panel is warped outward, the notch in the wall panel can be pulled toward the floor panel. This has the advantage that the end portions of the floor panels can be brought into close contact with each other without creating any gaps, and as a result, the building can be constructed successfully.
