DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for exhausting room air in an air conditioning system by providing an exhaust port at a field edge having a function of supporting a ceiling plate.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a pair of T-bar portions 1 having an inverted T-shaped cross section are provided side by side with a gap therebetween.
A so-called W bar for a system ceiling in which substantially middle portions of the vertical pieces 2 are integrally connected by a connecting horizontal piece 3 is known. An opening 22 is provided at the center of the connecting lateral piece 3 at the edge A, and a diffuser in the air conditioning system is attached to the room to supply air to the room by using the opening 22. In another place, the opening 22 provided at the center of the connecting horizontal piece 3 is used as an exhaust hole for exhausting room air returning as it is. Here, when the opening 22 is used as an exhaust hole, the underside of the ceiling can be seen from the opening 22. Therefore, conventionally, as shown in FIG.
1 so that the ceiling can not be seen from the opening 22.

[0003]

However, in the conventional example shown in FIG. 4, it is necessary to separately attach a return cover 20 by using a mounting bracket 21 so that the back of the ceiling cannot be seen through the opening 22. Therefore, the number of members increases,
There was a problem that the cost was increased and the construction was troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. It is an object of the present invention to make it impossible to see the inside of the ceiling from an exhaust port, and to separately require a return cover or a mounting bracket for the return cover. In addition, the present invention is to provide a rim in which a diffuser can be attached with a simple process if necessary.

[0005]

According to the present invention, a pair of T-bars 1 having an inverted T-shaped cross section are arranged side by side with a gap therebetween to form a substantially intermediate portion of a vertical piece 2 of both T-bars 1. The lower horizontal pieces 4 projecting to both sides from the lower end of the vertical piece 2 of the T-bar section 1 are connected to each other by a connecting horizontal piece 3, and the outer lower horizontal piece 4 is a ceiling plate 5.
A ceiling plate mounting portion 6 for mounting the end portion of each of the above, and the lower lower horizontal portion 4 as an exhaust outlet concealing piece 7, a gap is formed between the two exhaust outlet concealing pieces 7, and a connecting horizontal piece portion is formed. The exhaust port 8 is provided in a portion corresponding to the portion directly above the exhaust port concealing piece 3 of FIG.
The end portion of the T-bar portion 1 in the same direction as the longitudinal direction is made close to each other, and a portion between the adjacent exhaust ports 8 of the connecting horizontal piece 3 is formed as a cuttable portion 9. By adopting such a configuration, the problems of the conventional example described above have been solved and the object of the present invention has been achieved.

[0006]

A pair of T-bars 1 having a reverse T-shape in cross section are arranged side by side with a gap therebetween, and the substantially middle portions of the vertical pieces 2 of the two T-bars 1 are integrally joined by a connecting horizontal piece 3. A ceiling plate mounting for connecting the outer lower horizontal portion 4 of the lower horizontal portion 4 protruding to both sides from the lower end of the vertical portion 2 of the T-bar portion 1 on the end of the ceiling plate 5 The lower horizontal piece 4 is formed as an exhaust port concealing piece 7 and a gap is formed between the two exhaust port concealing pieces 7 so as to correspond to the portion just above the exhaust port concealing piece 7 of the connecting horizontal piece 3. By providing the exhaust port 8 in the portion, the exhaust port 8 is not hidden by the exhaust port hiding piece 7 so that the inside of the ceiling can be seen even when the field A portion is viewed from the room. In addition, the end portions of the exhaust ports 8 on both sides in the same direction as the longitudinal direction of the T-bar portion 1 are brought close to each other, and a portion between the adjacent exhaust ports 8 of the connecting horizontal piece 3 is formed as a cuttable portion 9. When the cuttable portion 9 is cut off, a large opening 10 can be formed in the center of the connecting horizontal piece 3 by cutting off the space between the two exhaust ports 8, and the diffuser 11 can be attached to this opening 10.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on embodiments shown in the accompanying drawings. The field edge A has a pair of T-bar portions 1 having an inverted T-shaped cross section arranged side by side with a gap therebetween, and substantially intermediate portions of the vertical piece portions 2 of both T-bar portions 1 are integrally connected by a connection horizontal piece portion 3. It is configured. A head 12 is provided at the upper end of the vertical piece 2 of the T-bar 1. Outer lower horizontal part 4 of lower horizontal part 4 protruding from both ends from the lower end of vertical bar part 2 of T-bar part 1 has ceiling plate mounting part 6 for mounting an end of ceiling plate 5 and Also, the inner lower horizontal piece 4 is an exhaust port hiding piece 7.
Here, a gap is formed between both the exhaust port hiding pieces 7. As shown in FIGS. 1 and 2, an elongated exhaust port 8 elongated in the longitudinal direction of the T-bar section 1 is provided at a portion of the connecting horizontal piece 3 directly above the exhaust port concealing piece 7. As shown in FIG. 2, both ends of the exhaust ports 8 on both sides in the same direction as the longitudinal direction of the T-bar portion 1 are close to each other. The cut-out portion 9 can be knocked out.

[0008] The field edge A having the above-described configuration is connected to a C-channel (not shown) attached to a suspension bolt (not shown) suspended from a slab (not shown) by a hanging bracket (not shown).
The head 12 on the top of the T-bar portion 1 of the ridge A is attached, and the end of the ceiling plate 5 is placed on the ceiling-plate placing portion 6 of the T-bar portion 1 to construct the system ceiling. It constitutes. Then, return air in the air conditioning system is exhausted from the exhaust port 8. Here, the knockable outable portion 9 between the two exhaust ports 8 adjacent to the connecting horizontal piece 3 is cut with gold scissors or the like, so that both exhaust ports 8 are cut off and the center of the connecting horizontal piece 3 is cut off. Large opening 1
0 can be formed in the opening 10 as shown in FIG.
Which can be fitted and mounted. Figure 1,
Arrows in FIG. 3 indicate the flow of air.

[0009]

As described above, according to the present invention, a pair of T-bars having an inverted T-shaped cross section are arranged side by side with a gap therebetween, and the substantially middle portions of the vertical pieces of both T-bars are connected to each other. Connected together by T
Outer lower horizontal part of the lower horizontal part protruding from both ends from the lower end of the vertical part of the bar part is used as a ceiling plate mounting part for mounting the end of the ceiling plate and inner lower horizontal part. Since the air outlet is a hidden piece, the air outlet is not concealed from the air outlet and the inside of the ceiling is not visible even when looking at the edge of the room. As a result, there is a separate return cover as in the past. It does not require mounting brackets for return and return covers, reduces the number of parts, lowers costs, and improves workability.
An exhaust port is provided in a portion of the connecting horizontal piece directly above the exhaust port concealing piece, and the ends of the T-bar portions of both exhaust ports in the same direction as the longitudinal direction are brought close to each other so that the connecting horizontal piece approaches The part between the two exhaust ports is cut off, so if you want to attach a diffuser, cut off the cut-off part to cut off both exhaust ports to form a large opening in the center of the connecting horizontal piece. It is possible to attach a diffuser to this opening.
