By locking the locking jaws 7a of one connecting edge 7 and the locking receiving groove 7b of the other connecting edge 7, the vertical center beam members 3a and 3b are combined, and both the clamping protrusions The edges 5, 5 are opposed to each other, and a panel holding groove 8 is formed between these opposing sandwiching protrusions 5, 5. In this case, it is preferable to determine the lengths of the connecting edge 7 and the clamping edge 5 in advance so that the holding groove 8 matches the panel holding groove (not shown) of the door. In addition, in the example shown above, two connecting edges 7 protrude from the fixed edge 6, but
However, the connecting edge 7 is not necessarily limited to the illustrated example, and one or three or more may be provided, and the shape thereof is not necessarily limited to the illustrated example above, as long as it can connect the facing vertical members 3a and 3b. It is not limited to what is shown in . For example, as shown in Figure 3,
The connecting edge 7 of one vertical center member 3a and the connecting edge 7 of the other vertical center member 3b are overlapped, and this overlapping portion 9
The structure may be such that it is fixed with a screw from between the clamping protrusions 5, 5.

Moreover, a decorative uneven surface 10 is formed on the outer surface of each of the vertical center beam members 3a, 3b. However, such a decorative part 10 is
It is only necessary to provide it on the inside vertical crosspiece member 3b, and it is not necessarily necessary to provide it on the inner vertical center member 3b.

When installing one of the vertical middle beam members 3a of the above structure on the outer surfaces of the upper and lower frames 1a, 1b of the door A, first cut out the upper and lower ends of the clamping ridge 5 of the vertical center beam member 3a, and This notch 11 is fitted into the upper and lower frames 1a and 1b. At this time, the upper and lower frames 1a,
The base edge 6 of the vertical center member 3a comes into contact with the outer surface 12 of 1b. Therefore, a working hole 13 is bored in the side wall of the other side of the upper and lower frames 1a, 1b, and a tool (not shown) such as a screwdriver is inserted into the working hole 13 to connect the outer surface 12 of the one side to the vertical center frame. The base edge 6 of the member 3a may be fixed with screws. Next, the upper and lower frames 1a,
1b is placed opposite to the vertical center member 3a, and when its notch 11 is fitted into the upper and lower frames and pressed strongly against the opposite side, the connection edge 7 of this vertical center member is engaged. The stop jaw part 7a is resiliently engaged with the lock receiving groove part 7b of the connection edge 7 of one of the vertical frame members 3b, and the vertical frame 3 is integrated with the upper and lower frames 1a and 1b in between. configured.

Next, since the vertical center members 3a and 3b protrude outward, caps 14 made of cast aluminum or the like cover the upper and lower end surfaces thereof. A holding piece 14b is provided below the cap body 14a. The cap 14 has upper and lower frames 1a,
1b, and is fixed by inserting the holding piece 14b into the hollow end and fixing the holding piece 14b to the fixed edge of the vertical center member 3a with screws. Covering the door A with the cap 14 not only improves the appearance of the door A, but also prevents rainwater and the like from entering the hollow portion of the vertical member.

Furthermore, although the horizontal middle bar 2 is provided on the door A, the vertical middle bar member 3 is attached to the horizontal middle bar 2 in the same manner as described above.
a and 3b can be attached. That is, first, the center part of one of the vertical middle crosspiece members 3a is cut out to form the middle crosspiece fitting part 15, and the horizontal middle crosspiece 2 is attached to this fitting part 15.
are fitted, and the horizontal middle crosspiece 2 and the vertical middle crosspiece member 3a are screwed together in the same manner as above. Next, the other vertical center member 3b is made to face the vertical center member 3a from the other side with the horizontal center member 2 interposed therebetween, and the center member is fitted into the fitting portion 15, and is strongly pressed to both Vertical center member 3
The connecting edges 7, 7 of a, 3b are locked and engaged.

In addition, by constructing the vertical middle beams 3 on the upper and lower frames 1a and 1b as described above, a plurality of vertical beams 3 and the upper and lower and vertical frames 1a, 1b and 1c, horizontal middle beams 2, etc. Rectangular panel frames are constructed, and continuous panel holding grooves are formed on the inner peripheries of these panel frames, and panels such as cast panels 20 and glass plates are fitted into these holding grooves. Also in the vertical center beam 3, the panel 20 is held in a panel holding groove 8 formed between the clamping edges 5, 5 of the inner and outer vertical center beams 3a, 3b.
