(Prior art and its problems) In recent years, a new type of building called an intelligent building has appeared, which can install a large amount of information devices and can make full use of it in the age of mass information technology. There is. In other words, in such an intelligent building, the floor structure can connect the cables arranged under the floor and the information equipment on the floor at any position, and the ceiling structure does not impair the appearance of the upper floor. It must be possible to connect the cables to the cables below the ceiling below the floor, and also to facilitate the maintenance and inspection of the cables below the floor and above the ceiling.

However, in the conventional ceiling structure, the ceiling material is fixed to the ceiling base, or even in the case of metal fitting construction, the inverted T-shaped material (2) is hung from the body as shown in Fig. 6 and further adjacent. Ceiling material (4)
In order to prevent unevenness with the above, the front and rear ends of the ceiling material (4) are placed on the horizontal flange portion (3) of this inverted T-shaped material (2) and the kerf groove (7 ) To A method was used in which a mold material was fitted, the two were connected, and ceiling construction was performed. In the above cases, the appearance of the ceiling is excellent, but since all the ceiling materials (4) are connected, it is difficult to open and close the ceiling material (4), and maintenance and inspection of the cables behind the ceiling are difficult. It was not easy to do and was not suitable for intelligent buildings.

(Object of the present invention) The present invention has been made in view of the drawbacks of the conventional example,
The purpose is to provide an epoch-making ceiling structure suitable for an intelligent building, not only for its excellent appearance, but also for extremely easy maintenance and inspection of a large amount of cables laid behind the ceiling.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention: A hanger (20) is attached to a channel (19) suspended from an upper floor (1).
Or, the inverted T-shaped member (2) is hung or fixed via a wire (not shown). The inverted T-shaped members (2) are thereby arranged substantially parallel.

The front and rear ends of the ceiling material (4) are placed on the horizontal flange portion (3) of the inverted T-shaped material (2), and the ceiling material (4) is laid between the inverted T-shaped material (2).

Side plates (5) having a substantially L-shaped cross section are attached to the sides of the ceiling materials (4) adjacent to each other so as to be bilaterally symmetrical.

The side plate (5) of the other ceiling material (4) is attached to the inverted T-shaped material (2).

Side plate (5) of one ceiling material (4) Engagement piece (6) that can extend outward from the upper end of the side plate (5) of another ceiling material (4) adjacent to both sides The side plate (5) attached to the other ceiling material (4) so as to be movable along the inverted T-shaped material (2). Allows push-up and removal.

The technical means called; is adopted.

(Operation) When one ceiling material (4) is pushed up, the engaging piece part (6) of the side board (5) of the ceiling material (4) is adjacent to the side board (5) of the ceiling material (4). Come off.

At this time, the side plate (5) of the adjacent ceiling material (4) is an inverted T-shaped material.
Since it is engaged with (2), the side plate (5) reinforces the ceiling material support frame of the inverted T-shaped material (2), and
As one ceiling material (4) is pushed up, adjacent ceiling materials (4) will not be lifted up together.

When the side plate (5) comes off, replace the ceiling material (4) with the horizontal ceiling material.
The ceiling material (4) placed on (4) or removed is placed in the room to open the ceiling.

A worker leans over the ceiling from the opening,
Maintain and inspect the cable (8) laid along (A) or supported by the cable rack (21).

The ceiling material (4) can be removed every other sheet, and the adjoining ceiling material (4) can be moved along the inverted T-shaped material (2) at any position on the ceiling. Since it can be opened at any position, it is possible to easily perform maintenance and inspection at any place on the ceiling.

(Examples) Hereinafter, the present invention will be described in detail with reference to illustrated examples. Ceiling material
As shown in Fig. 2, (4) has the undersides of the front and rear ends cut stepwise by the thickness of the horizontal flange (3) of the inverted T-shaped material (2), and the kerf groove is formed at the center of both sides. (7) is recessed in the longitudinal direction. The inverted T-shaped member (2) is composed of a horizontal flange portion (3) and a web (10) provided upright from the center of the horizontal flange portion (3).
On both side surfaces of (0), inwardly directed L-shaped piece portions (17) are provided so as to project, and slide grooves (12) are formed. Side plate
(5) is a substantially L-shaped cross section composed of a horizontal piece (13) and a vertical piece (14), and the upper end of the vertical piece (14) has a horizontal piece (13).
There are those that are curved to the side and those that are curved to the opposite side of the horizontal piece part (13), with the former as the bending piece part (15),
The latter is the engaging piece (6). The horizontal piece (1
3) is previously inserted and adhered to the kerf groove (7) of the ceiling material (4). In this case, the curved piece (15) which is curved inward.
Side plates (5) having the same are attached to both sides of the same ceiling material (4) so as to be symmetrical, and the side plate (5 having the engaging piece part (6) extended outward is provided. ) Are attached to both sides of the same ceiling material (4).

Then, as shown in FIG. 1, the suspension bolt (16) is suspended from the body (A), and the channel (19) is suspended by the suspension bolt (16).
A hanger (20) is hung vertically on this channel (19),
A large number of inverted T-shaped members (2) are hung from the hanger (20) substantially parallel to each other at predetermined intervals. Channel (19) and inverted T-shaped material
It will be placed almost at a right angle to (2). Next to the side plate (5)
Invert the cut-off steps (9) at the front and rear ends of the ceiling material (4) to which the
Inverted T-shaped material placed on the horizontal flange (3) of the material (2)
The ceiling material (4) is laid between (2), and the ceiling material (4) having the above-mentioned inward curved piece portion (15) and the outward engaging piece portion.
The ceiling material (4) having (6) is laid alternately, and the outward engaging piece (6) is locked onto the inwardly curved piece (15). This allows the ceiling material (4) to have the outward engaging piece (6).
It can be easily removed from the adjacent ceiling material (4) by pushing up.

Next, the shape of the end of the side plate (5) having the inward curved piece (15) will be described. FIG. 2 shows a first embodiment of the end portion,
The extension of the vertical piece (14) is bent inward at a right angle, and the lower end of the extension (14a) is attached to the slide groove (1) of the lower L-shaped piece (17).
The upper end spring portion (14b) which is slidably fitted in 2) and curved in an arc shape is slidably fitted in the upper L-shaped piece portion (17). As a result, the extension portion (14a) slides in the slide groove (12) with some elasticity.

As a second embodiment of the end shape, a case as shown in FIG. 3 can be considered. That is, the extension portion (14a) is a separate body from the vertical piece portion (14), and the horizontal piece portion (13) of the side sap material (5) is folded back to form the lower end horizontal piece portion (14c) of the extension portion (14a). ) And the extension (1
The upper end of 4a) is fitted in the engaging piece portion (6). With this, even if the length of the side sapwood (5) is appropriately cut according to the size of the ceiling, the extension part (14a) can be inserted into the cut end of the side sapwood (5), and the extension part If the (14a) is a one-piece type, the sapwood has various sizes from short to long (5)
However, in this case, one kind of sapwood (5) is sufficient.

The third embodiment of the end shape is the case as shown in FIG. 4, in which a separate L-shaped metal fitting (11) is fixed to the vertical piece (14) by welding, bolting or any other suitable method. A spacer (18) inserted in the slide groove (12) slidably supports the web (10) of the inverted T-shaped member (2). In this case, ceiling material (4)
In order to adjust the laying interval, or to move the ceiling material (4) adjacent to the removed ceiling material (4), slide the L-shaped metal fitting (11) into the slide groove ( It is desirable to slide along the spacer (12), and a slightly curved separate spacer (18) is fitted into the slide groove (12), and an L-shaped metal fitting (11) is provided between the spacer (18) and the web (10). It is also possible to slightly extend one piece when the L-shaped metal fitting (11) is fitted and to slidably fit the L-shaped metal fitting (11) by the elastic force generated at that time as in the case of the extension portion (14a). Also, the spacer (18) and the L-shaped metal fitting (1
1) can be rotated or tilted about an axis and integrated so as to be fixed at the tilting point, and when the L-shaped metal fitting (11) is attached, the spacer (18) is raised and the slide groove (12 ) L-shaped metal fittings
(11) may be fixed. In this case ceiling material (4)
This is convenient because the spacer (18) also moves with the movement of. By doing so, the adjoining ceiling material (4) can be freely moved and opened over the entire ceiling, which facilitates inspection.

If there is no need to slide, the vertical piece of side sapwood (5)
The extended part of (14) may be processed into a projecting piece and inserted into and supported by a slit (not shown) provided in the web (10). If unnecessary, the L-shaped metal fitting (11) may be removed. The side plate (5) may be left free.

In addition, the hinge part of the L-shaped metal fitting (11) can be bent and extended freely,
The L-shaped metal fitting (11) may be pivotally or erected on the side plate (5) about an axis and fixed at the erected position so as not to be bulky during transportation. Further, as shown in FIG. 5, the engaging piece portion (6) is formed in an inverted U shape and is loosely fitted to the upper end of the other side plate (5) that is bent, and the dimension of the member is measured. You may make it absorb an error and an assembly error.

In the ceiling structure configured in this way, when performing maintenance and inspection of the cable (8) laid inside the ceiling, the engaging piece
The ceiling material (4) having one (6) is pushed up and removed from the inward curved piece portion (15) of the side plate (5) of the other ceiling material (4) which is adjacent to the ceiling material (4). When the side plate (5) is removed, the ceiling material (4) is placed on the horizontal ceiling material (4), or the removed ceiling material (4) is dropped into the room to open the ceiling. A worker leans over the ceiling through the opening and performs maintenance and inspection of the cable (8) laid inside the ceiling. When the ceiling material (4) having the inwardly curved piece (15) is pushed up by mistake, the side plate (5) of the ceiling material (4) becomes the web (10) of the inverted T-shaped material (2). Because it is supported, it is not lifted and it is immediately obvious that it is an error.

In this way, at least one piece of the ceiling material (4) can be removed, and in some cases, by shifting the ceiling material (4) on the curved piece portion (15) side as described above, it is possible to remove any ceiling material. Opening at any position is possible, and maintenance and inspection can be easily performed at any place on the ceiling.

(Effect) As described above, since the side plates are attached to the sides of the ceiling material as described above, the ceiling material is reinforced so that the ceiling material does not hang down even after long-term use. Since the engaging piece that does not occur and can extend outward from the side plate of one ceiling material is locked to the side plate of another ceiling material that is adjacent to the side plate, the length of the engaging portion is the reference. Even if the period elapses, no unevenness occurs between the ceiling materials that are adjacent to each other, and the appearance does not deteriorate, and side plates are attached to the sides of the ceiling materials that are adjacent to each other. Since it is possible to push up and remove one ceiling member by locking the engaging piece portion that can be extended outward from the side plate of one ceiling member to the side plate of another adjacent side plate. You can easily remove the ceiling material by pushing up the ceiling material with the joint piece, and remove the ceiling material every other piece on the ceiling. It has the advantage that it can be removed and opened, and the maintenance and inspection of cables under the ceiling can be performed extremely easily.
