BACKGROUND OF THE INVENTION
The present invention relates to a door frame joint material that is attached to two door frames that have a concave groove on a side portion and are mounted in a right angle direction.
[0002]
[Prior art]
A construction example of a door frame according to a conventional example in the case where two doors 48 and 49 are arranged close to each other at right angles will be described with reference to FIGS. 3 (A) to 3 (D). As shown, a door frame 56 having concave grooves 54 and 55 formed on both sides is fixed to a column 53 to which wall members 51 and 52 are attached, and a door stop 58 is attached to an inner groove 57 of the door frame 56. . Then, as shown in FIG. 3 (B), one end of a casing 59 which is a door frame joint material having an L-shaped cross section is inserted into one concave groove 55 of the door frame 56, and as shown in FIG. 3 (C), With the other end of the casing 59 mounted in the recessed groove 61 of the other door frame 60, the door frame 60 having the door stop 62 is attached to the column 53 via the wall member 52. Thereafter, as shown in FIG. 3D, casings 65 and 66 having one end fitted in the other concave grooves 54 and 63 of the door frames 56 and 60 are attached, and the construction is completed.
[0003]
[Problems to be solved by the invention]
However, in the construction of the door frame according to the conventional example, the casing 59 may fall off unless the casing 59 in FIG. 3C, the other end of the casing 59 is fitted in the recessed groove 61 of the door frame 60, and the door frame 60 is held on the column 53 in a state where the door frame 60 is held just vertically. There is a problem that it is necessary to fix it, and it is difficult to work alone because it is extremely nerve-intensive.
On the other hand, as shown in FIG. 3E, when two or three doors are close to each other at right angles, both ends of the casing 59 having an L-shaped cross section are recessed when both door frames 56 and 60 are fixed to the pillars in advance. There was a problem that it was physically impossible to fit into the grooves 55 and 61.
The present invention has been made in view of such circumstances, and an object thereof is to provide a door frame joint material having extremely good workability.
[0004]
[Means for Solving the Problems]
The door frame joint material according to claim 1, which meets the above-mentioned purpose, has a recessed groove (17, 19) on each side and is attached to two door frames (16, 18) arranged in a right angle direction. A frame joint material (10),
The long piece (13) and the short piece (14) are connected to each other in an L-shaped cross section, and the one end (15) of the long piece (13) is fitted into the concave groove (17) of one of the door frames (16). A first member (11);
The other end of the door frame (18) is inserted into the groove (19), and the inner groove (19) of the groove (19) is inserted into the groove (19). The thickness (t2) of the short piece (14) is subtracted from the central portion (22) having a thickness including the thickness (t3) of the groove wall (21) on one side and the thickness (w2 + t3) of the central portion (22). A second member (12) comprising a base (23) having a thickness,
The length (a) of the base (23) is the same as the length of the short piece (14), and the notch (23a) provided outside the base (23) of the second member (12) The short piece (14) of the first member (11) is fitted to connect the first member (11) and the second member (12) .
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention.
FIG. 1 is a cross-sectional view showing a use state of a door frame joint material according to an embodiment of the present invention, and FIGS. 2A to 2E are process diagrams showing a construction procedure of the door frame joint material. is there.
[0006]
As shown in FIG. 1, a door frame joint material 10 according to an embodiment of the present invention includes a first member 11 made of wood or a plastic material and having a predetermined length (for example, 1 m to 2 m). The second member 12 is included. The first member 11 is formed in an L shape having a long piece 13 and a short piece 14 whose cross sections are connected at right angles, and the thickness t1 of the long piece 13 is a concave groove 17 of the door frame 16 into which one end 15 thereof is fitted. The inner width w1 is equal to or slightly smaller than the inner width w1. The thickness t2 of the short piece 14 is about 1/3 to 2/3 (preferably about 1/2) of the thickness t1 of the long piece 13.
[0007]
On the other hand, the second member 12 has a tip portion 20 (one end portion) that closely fits into the recessed groove 19 of the door frame 18 that is arranged orthogonal to the door frame 16 and a thickness t3 of the groove wall 21 on one side of the recessed groove 19. From the central part 22 having a thickness obtained by adding the inner width w2 of the concave groove 19, and a base part 23 (the other end part) obtained by subtracting the thickness t2 of the short piece 14 of the first member 11 from the thickness (w2 + t3) of the central part 22 It has become. The length a of the base 23 is the same as the length of the short piece 14, and the short piece 14 of the first member 11 is fitted into a notch 23a provided outside the base 23 which is the other end of the second member. Thus, when the first member 11 and the second member 12 are connected as shown in FIG. 1, the boundary portion 24 between the first member 11 and the second member 12 cannot be easily identified.
[0008]
Next, the case where this door frame joint material 10 is attached to the door frames 16 and 18 of two doors orthogonal to each other will be described with reference to FIGS.
As shown in FIG. 2 (A), the door frame 18 is attached to the inner side of the pillar 27 having the wall members 25 and 26 on both sides, and the door is brought into contact with the groove formed on the inner side (surface side) of the door frame 18. 28 is installed. The door frame 18 has a groove 29 in addition to the groove 19 described above.
[0009]
Next, as shown in FIG. 2 (B), another door frame 16 is attached in a state orthogonal to the door frame 18, and a door contact 30 is formed in a groove formed on the inner side (front side) of the door frame 16. Install. Then, as shown in FIG. 2 (C), the front portion 20 of the second member 12 is inserted into the concave groove 19 of the door frame 18, and then, as shown in FIG. The one end 15 is fitted into the concave groove 17 and the short piece 14 of the first member 11 is fitted into the notch 23 a of the second member 12.
[0010]
Thereafter, if necessary, in order to firmly connect the first member 11 and the second member 12, as shown in FIG. 1, they may be fixed with a nail 31 or a screw, or an adhesive may be used. The first member 11 and the second member 12 may be fixed.
Then, as shown in FIG. 2 (E), door frame joint members 33 and 34 having a well-known structure having an L-shaped cross section are attached to the concave groove 29 of the door frame 18 and the concave groove 32 on the other side of the door frame 16, respectively. become.
[0011]
In the embodiment described above, the first member 11 is formed in an L-shaped cross section in which the long piece 13 and the short piece 14 are connected at a right angle, and the notch into which the short piece 14 of the first member 11 is fitted into the second member. 23a is provided, but the present invention can be applied to other divided modes as long as the first member can be attached to the door frame 16 after the second member is attached to the door frame 18. The For this purpose, it is only necessary that the second member attached to the concave groove 19 does not exist in the moving region of the first member formed when the first member is inserted into the concave groove 17.
[0012]
【The invention's effect】
In the door frame joint material according to claim 1 , after the second member is mounted in the concave groove of one door frame, the first member is not subjected to the interference of the second member, and is recessed in the other door frame. Since it has a structure that can be fitted, the door frame joint material can be constructed after both door frames are attached at a predetermined angle, and workability is improved.
In addition, since the long piece and the short piece of the first member are connected to each other in an L-shaped cross section, a notch in which the short piece of the first member is closely inserted is formed outside the other end of the second member. The combined state of the first member and the second member is improved, and a stronger door frame joint material can be provided.
