Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a ceiling equipment line plate, and more specifically, for example, when a plurality of lighting fixtures are arranged side by side on a ceiling surface, they are placed between the lighting fixtures. The present invention relates to a plate for an equipment line used when arranging equipment items side by side on a ceiling surface, such as a plate installed to close the equipment.

[Conventional technology]

As shown in FIG. 5, the ceiling equipment line has a structure in which a large number of equipment items such as a lighting fixture 20 accommodating a fluorescent lamp 21 are arranged in a line on a ceiling surface covered with a ceiling panel 10. Instead of the luminaire 20, a ventilation device or a sound device may be provided. The lighting fixture 20 is attached to the ceiling panel 10 via a so-called T-bar 11. The T-bar 11 is a support member having an inverted T-shaped cross section, and is attached to the joint between the ceiling panels 10 to support the ceiling panel 10. Lighting fixtures arranged in a straight line 2
Since 0 and 20 are arranged on a straight line at regular intervals, a means for closing the gap between the lighting fixtures 20 and 20 is required.

Conventionally, as a means for closing the gap between the lighting fixtures 20 and 20,
The equipment plate 30 made of a steel plate as shown in FIG. 6 was used. This equipment plate 30 has a horizontal flange portion 31 formed by vertically bending the opposite sides and further bending the tip end in the horizontal direction. As shown in FIG. 7, when the equipment plate 30 is inserted into the gap between the lighting fixtures 20 and 20, the horizontal flange portion 31 is mounted on the flange portions 24 of the lighting fixtures 20 on both sides. In addition, in order to prevent the equipment plate 30 from coming off or falling, the equipment plate
The chain member 32 connects the 30 and the lighting device 20. As shown in FIG. 8, the horizontal flange portion 31 of the equipment plate 30.
The side that is orthogonal to the direction T that supports the ceiling panel 10
The equipment plate 30 is mounted on the bar 11 in a mounted state.

[Problems to be solved by the device]

However, in the conventional equipment plate 30 as described above,
There was a problem as described below.

First, the equipment plate 30 is manufactured from a steel plate so as not to be damaged or deformed during transportation or handling, therefore, it is difficult to cut at the construction site, and the lighting fixture 20, There is a problem that it is difficult to change the dimensions on site according to the width dimensions of 20 and so on.

Further, as described above, the equipment plate 30, since the horizontal flange portion 31 is only placed on the flange portion 24 of the lighting fixture, if the equipment plate 30 is displaced or the gap between the lighting fixtures 20, 20 is expanded and deformed. However, there is a problem that the equipment plate 30 may fall or a gap may be created between the equipment plate 30 and the lighting fixture 20. Conventionally, the chain member 32 is used to prevent the equipment plate 30 from falling, but there is a drawback that the chain member 32 is attached one by one, which is a troublesome work and extra cost.

Therefore, the problem of this invention is to solve the above-mentioned problems of the conventional equipment plate, to facilitate dimensional adjustment and handling at the site, to have sufficient strength and durability, and to be easy to construct. It is to provide a plate for a ceiling equipment line that does not fall.

[Means for Solving the Problems]

A ceiling equipment line plate according to the present invention, which solves the above-mentioned problems, is an equipment line plate installed between equipment items when a plurality of equipment items are arranged side by side on a ceiling surface, and is easy to cut. It is composed of a substrate made of a material and a frame material provided along opposite sides of the substrate, and a locking groove for locking a part of the equipment is provided between the side end surface of the substrate and the frame material. The end of the frame member in the longitudinal direction is located inside the end of the substrate.

Any material can be used for the substrate as long as it is a material that can be easily cut. For example, it is preferable to use the same material as the material for the ceiling panel, such as gypsum board, fiber board, and other inorganic plates. If the same material as the ceiling panel is used, it is preferable because it has good integration with the surrounding ceiling surface.

Although the shape of the substrate varies depending on the arrangement structure of equipment such as lighting equipment, it is usually formed in a rectangular shape having a constant area. However, since the equipment line plate of the present invention can be changed in size on site, it is not necessary to exactly match the installation size on site.

The frame material is formed of metal such as steel or aluminum or synthetic resin, and it is not necessary to use a material that can be easily cut like a substrate, and it is preferable that the frame material has excellent strength and durability capable of protecting the substrate. The shape of the frame material should be such that when it is attached to the side of the board, a locking groove can be formed between it and the side end surface of the board. And position. Specifically, for example, if a frame member having an L-shaped cross section is used and one side of this L-shaped frame member is fixed to the upper surface of the substrate and the other side is arranged so as to face the side end surface of the substrate, A locking groove that opens downward is formed between the other side and the side end surface of the substrate. If such an L-shaped frame member is used, the manufacturing is simple and the reliable locking function can be exerted. However, structures other than the L-shaped frame can be adopted as long as the functions described above can be exhibited. Further, if the structure of the engaging portion such as the flange portion of the equipment changes, the structure of the frame member and the engaging groove also changes.

The frame member is attached to the two opposite sides of the substrate. That is, with the equipment line plate mounted between the equipments, the frame material is attached to the side edges adjacent to the equipments on both sides to form the locking grooves.

The longitudinal end of the frame member is located inside the end of the substrate. That is, the substrate is projected to the outside of the end of the frame material. The larger the protruding amount of the substrate, the larger the adjustment amount of the length of the equipment line plate. However, if the length of the frame material is too short, the effect of protecting the substrate by the frame material cannot be sufficiently exerted. Therefore, it is preferable to set the amount of protrusion of the substrate to an extent necessary and sufficient for adjusting the length of the equipment line plate. The frame member may be continuously provided in the longitudinal direction with respect to the side edge of the substrate, or may be intermittently provided in the longitudinal direction.

The equipment line plate of the present invention can be applied to the construction of various equipment items arranged side by side on the ceiling surface, such as a ventilation device and a sound device, in addition to the above-described lighting equipment.

[Action]

Not only is the equipment line plate placed on a part of the equipment, but it can also be locked to equipment such as lighting fixtures with the locking groove that is configured by the frame material provided along the opposite side of the board. By doing so, the equipment line plate can be securely attached. Even if the equipment line plate tries to move in the horizontal direction due to impact or vibration, the equipment line plate cannot move largely if the locking groove is locked to a part of the equipment item. Therefore, the problem that the equipment line plate moves to form a gap between the equipment line plate and the equipment line plate and the equipment line plate drops is solved.

When the end portion of the frame material in the longitudinal direction is inside the end portion of the substrate, the end portion of the substrate made of an easily cuttable material can be cut. Therefore, the dimension of the equipment line plate can be easily adjusted by cutting the end portion of the substrate according to the size of the installation place of the equipment line plate.

A board made of a material that is easily cut is inferior to conventional steel sheets in terms of strength and durability, but since the frame material is provided along the opposite side of the board, the board is protected by the frame material. It is possible to maintain sufficient strength and durability.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the structure of the equipment line plate 40,
A substantially square substrate 41 made of an easily cuttable material such as an inorganic plate is attached with a frame member 42 having an L-shaped cross section made of a metal extruded product or the like along two opposing sides of the substrate 41. ing. The frame member 42 has one side of the L shape fixed to the upper surface of the substrate 41,
The other side of the L-shape hangs outward from the side end surface of the substrate 41,
It is arranged so as to face the side end surface of the substrate 41. The space between the frame member 42 and the side end surface of the substrate 41 is used as the locking groove 43.

The length of the frame member 42 is shorter than the length of the substrate 41,
The longitudinal end of the frame member 42 is inside the end of the substrate 41. That is, the end portion of the substrate 41 projects by the length X from the end portion of the frame member 42 in the longitudinal direction. This protrusion amount X becomes the length adjustment amount of the equipment line plate 40.

2 to 4 show the installation state of the equipment line plate 40 having the above structure. In the figure,
The same reference numerals are attached to the structural parts common to the conventional example shown in FIGS.

As shown in FIG. 3, the equipment line plate 40 is mounted between the lighting fixtures 20 and 20. A flange portion 24 is provided at the end of the lighting fixture 20, 20.
The tip of is slightly bent upward. The structure of the flange portion 24 may be the same as the conventional one. The bent portions at the tip of the flange portion 24 of the lighting fixture 20 are fitted and locked in the locking grooves 43 at both ends of the equipment line plate 40.
Even if the equipment line plate 40 moves to the left or right,
Since the hanging side of the frame member 42 is caught on the flange portion 24 of the lighting fixture 20, the equipment line plate 40 does not move significantly.

As shown in FIG. 4, the equipment line plate 40 is placed on the T-bar 11 for supporting the ceiling panel 10 in the width direction of the lighting fixture 20. If T-bars 11,1 on both sides
When the interval of 1 is shorter than the length of the equipment line plate 40, both ends of the substrate 41 are cut to adjust the dimensions. That is, the length of the substrate 41 may be adjusted by cutting the end portion of the substrate 41 at a position outside both ends of the frame member 42 so as to match the interval between the T-bars 11, 11 at the construction site. . The board 41 can be easily cut by a cutting means similar to that of the normal ceiling panel 10.

[Effect of device]

The ceiling equipment line plate according to the present invention described above is constructed by engaging the engaging groove provided between the side end surface of the substrate and the frame member with a part of the equipment such as lighting equipment. The equipment line plate can be securely attached to the equipment item, and the problem that the equipment line plate is displaced or dropped after the construction is solved. Since a complicated fall prevention mechanism such as the conventional chain material is not required, the labor of construction can be saved and the construction cost can be reduced.

By cutting the end portion of the substrate made of the easy-cutting material, which protrudes to the outside of the longitudinal end portion of the frame member, it is possible to easily adjust the size of the equipment line plate. as a result,
Even if there are installation errors or variations in the installation dimensions of the ceiling panel or T-bar at the installation location of the equipment, you can easily respond by adjusting the dimensions of the equipment line plate, and one type for equipment with different dimensions. It is also possible to use it as a plate for the equipment line, and it will be extremely flexible.

As an easy-cutting material for forming substrates, board materials for ceiling panels, which are much lighter in weight and cheaper in manufacturing cost, can be used compared to conventional steel plates, which are the materials for equipment line plates. Plates are cheaper to manufacture and easier to carry and handle.

If the equipment line plate is formed of only a substrate made of an easily cut material, the strength and durability will be poor, and it may be damaged or deformed during transportation or handling, but it is chipped due to external force. Since the side portion of the substrate that is easily cracked or cracked is protected by the frame material, the equipment line plate will not be damaged or deformed, and will have practically sufficient strength or durability.
