DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
It will be explained based on. In the following description, the same parts as those of the related art are designated by the same reference numerals to simplify the description. In FIG. 1, reference numeral 10 denotes a joining tool for a building material panel according to the present embodiment. The joining tool 10 includes a locking member 11 fixed to an end surface of one building material panel 4 to be joined and the other building material. It is fixed to the end surface of the building panel 4 and both building material panels 4
4 is an engaging member 12 that is superposed on the locking member 11 when the locking member 11 is positioned at the joining position, and the locking member 11 is formed of a bendable plastic material into a plate shape.
A locking piece 13 bent upward is integrally formed at one end portion thereof, and the locking piece 13 is inserted in a portion where the engaging member 12 overlaps with the locking member 11. Engagement hole 1
4 has a schematic structure.

Next, these details will be explained.
The locking member 11 is formed into a substantially rectangular plate by punching a metal (for example, stainless steel), and as shown in FIGS. 1 to 3, the locking member 11 is provided at one end thereof. The piece 13 is formed in the shape of an isosceles triangle,
Further, in the present embodiment, as shown in FIGS. 1, 2, and 5, a substantially equilateral triangular biting piece 15 is integrally formed at the other end. The engaging piece 13 and the biting piece 15 are bent at approximately 90 ° so as to be on opposite sides.

The engaging member 12 is formed in a substantially rectangular plate shape by punching a metal such as stainless steel like the engaging member 11, and the engaging member formed at one end thereof. As shown in FIG. 6, the fitting hole 14 has a substantially equilateral triangle shape in a plan view. The maximum width of the engagement hole 14 is set to be substantially equal to or slightly larger than the maximum width of the locking piece 13. Then, in this embodiment, as shown in FIGS. 6 and 7, at the end opposite to the side where the engagement hole 14 is formed,
A biting piece 16 having the same shape as the biting piece 15 provided on the locking member 11 is integrally formed.

Next, the connector 10 constructed as described above.
A construction procedure for joining the wall panels 4 will be described using. First, the locking member 11 is fixed to one end of the upper end surface of the wall panel 4 by driving the biting piece 15 into the wall panel 4 (see FIG. 1). At that time, the locking piece 13 of the locking member 11 is not bent and is kept in a flat state, and is fixed so that the locking member 11 as a whole is positioned within the upper end surface of the wall panel 4.

On the other end side of the upper end surface of the wall panel 4,
The engaging member 12 and the biting piece 16 thereof are also attached to the wall panel
It is fixed by driving into (see FIG. 2). Then, at this time, the portion of the engaging member 12 in which the engaging hole 14 is formed is made to project from the other end side of the wall panel 4 by a predetermined length. As shown in FIG. 1, the protruding length is such that the distance L between the maximum width portion of the engagement hole 14 and the side edge of the wall panel 4 is determined by the locking member 11.
Distance D between the maximum width of the locking piece 13 and the side edge of the wall panel 4
Set to match.

In this way, the locking member 11 and the engaging member 1
The wall panel 4 to which the 2 is attached is brought into the construction site, and is lifted by the meat lane 5 or the like to be sequentially installed on the base 2 and the upper ends of the adjacent wall panels 4 are connected to each other. Prior to this, however, the locking piece 13 of the locking member 11 is bent upward by approximately 90 ° as shown in FIG.

From this state, the wall panel 4 to be installed is lifted up and positioned so that the engaging member 12 of the wall panel 4 to be installed is located above the locking member 11 of the existing wall panel 4. Then, it is lowered by the guidance of the worker. As shown in FIG. 2, the locking piece 13 of the locking member 11 is inserted into the engaging hole 14 of the engaging member 12 of the wall panel 4 that is lowered as the wall panel 4 is lowered.

When the engaging piece 13 and the engaging hole 14 are fitted together, the engaging member 12 is guided by the inclination of the engaging piece 13 and at the lowest position of the wall panel 4, as shown in FIG. As shown, the maximum width portion of the locking piece 13 and the maximum width portion of the engagement hole 14 are matched. At this time, the locking piece 1
Since the distance D between the maximum width portion of No. 3 and the side edge of the wall panel 4 and the distance L between the maximum width portion of the engaging hole 14 of the engaging member 12 and the side edge of the wall panel 4 are matched. By abutting the side edge of the lowered wall panel 4 against the side edge of the existing wall panel, the relative positional relationship between the locking piece 13 and the engagement hole 14 in the surface direction of the wall panel 4 is This is uniquely determined, and the two are completely matched in the vertical direction, and the engaging piece 13 and the engaging hole 14 are securely engaged with each other by the descending operation described above.

Further, since the locking piece 13 has a tapered shape, even if there is a positional deviation between the two wall panels 4 in a direction orthogonal to the plane of the wall panel 4, the inclination of the locking piece is increased. The deviation is gradually corrected by the above, and the maximum width portion of the locking piece 13 and the maximum width portion of the engagement hole 14 are set to have substantially the same size. By making them coincide with each other, as shown in FIG. 2, the positional deviation of both wall panels 4 in the direction orthogonal to the surface is corrected. Moreover, the distance D between the maximum width portion of the locking piece 13 and the side edge of the wall panel 4 and the distance L between the maximum width portion of the engagement hole 14 of the engaging member 12 and the side edge of the wall panel 4 are made equal to each other. Therefore, as shown in FIG. 2, the side surface of one wall panel 4 is held in a state of being abutted against the side surface of the existing wall panel 4.

After the lowering operation of the wall panel 4 is completed in this way, the locking piece 13 projecting above the engaging member 12 through the engaging hole 14 is indicated by an arrow in FIG. As shown, it is bent toward the locking member 11 side. As a result of this operation, the engaging member 12 is
It is clamped by the base of the locking member 11 and the locking piece 13,
The engagement member 12 is fixed to the locking member 11, and the upper end portions of both wall panels 4 are fixed.

As described above, when the wall panel 4 is joined using the joining tool 10 of this embodiment, the wall panel 4 to be joined is simply lowered along the side portion of the existing wall panel 4. Both wall panels 4 are automatically positioned, and
The upper end of the wall panel 4 is immediately fixed only by bending the locking piece 13.

Therefore, unlike the conventional case, it is not necessary to use the panel connector 6 and the work of driving the screw nail 7 is unnecessary. Moreover, since the work is a simple bending work, the wall panel 4 is joined. Is simplified and the construction time is greatly shortened. Further, since the work at a high place on the wall panel 4 is simplified, it is advantageous in terms of ensuring the safety of workers.

On the other hand, as the construction time is shortened,
The occupancy time of hoisting equipment such as the crane 5 holding the wall panel 4 is shortened, and its operating efficiency is also improved.

The shapes, dimensions, fixing methods, applicable members, etc. of the respective constituent members shown in the above embodiment are merely examples, and can be variously changed based on design requirements and the like. For example, in the above-described embodiment, an example in which the locking member 11 and the engaging member 12 are rectangular plate materials has been shown, but the invention is not limited to this, and a disc shape, a polygonal shape or the like can be arbitrarily selected. Is. Also, the bite piece 15.1
Although the example in which 6 is provided only on the end portions of the locking member 11 and the engaging member 12 is shown, it may be provided on the side portion or on three sides, and the shape thereof can be arbitrarily set. is there. Furthermore, the locking member 11 and the engaging member 1
The fixing of 2 can also be performed by using other fixing means such as bolts and nails. And, it goes without saying that the joining tool 10 shown in the above-mentioned embodiment can be applied to other building material panels such as a roof panel and a partition panel other than the wall panel 4.

The engaging piece is integrally formed, and an engaging hole through which the engaging piece is inserted is formed in an overlapping portion of the engaging member with the engaging member. It has the following excellent effects.

After the building material panel to be joined is lowered along the side portion of the existing building material panel, the locking piece of the locking member is inserted into the engaging hole of the engaging member, and then the locking piece. The panels for both building materials can be joined by a simple operation of bending. Therefore, the time required for the joining work can be significantly shortened, and the construction time can be shortened.

Further, since the joint portions of both building material panels are immediately positioned by the engagement of the locking pieces and the engagement holes, the panels are brought into a state of being abutted against each other. Since it is not necessary to use a connector, it is possible to eliminate the time required for its operation and attachment / detachment. From this point as well, the construction time can be shortened.

Further, when applied to a wall panel, a roof panel, etc., the work is performed at a high place, but by using the connector of the present invention, the work can be simplified and the safety of workers can be ensured. You can

On the other hand, as the construction time is shortened,
