Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a multifunctional ceiling frame material for a system ceiling that also serves as piping or wiring ducts.

``Prior Art'' Conventionally, there is a metal frame material having an H-shaped cross section as this kind of material (Japanese Utility Model Publication No. 44345/1983). By configuring the ceiling frame body in this way, it is possible to create a system ceiling, and ceiling panels, lighting equipment, etc. can be installed in a freely repositionable manner, and lighting equipment, etc. can be installed in the upper groove part.
It is convenient because it allows indoor wiring and various piping for telephones, TV antennas, HA equipment, etc. to be inserted through it.

Another type of this type uses a wiring duct whose bottom surface is closed with a joint bar (Japanese Patent Laid-Open No. 58
-150641). According to this, indoors,
Electrical cords can be easily connected by attaching and detaching the jointer.
It is convenient because it allows you to route and change the location of telephone lines, etc.

``Problem to be solved by the invention'' However, in the former case, the lower flange of the frame material that engages the ceiling board protrudes outward from the main part of the frame material, so it deforms during transportation and handling. Once deformed or damaged, it is difficult to repair, hinders the installation of ceiling panels, and has the drawback of spoiling the appearance. Incidentally, since the upper flange only connects hanging bolts etc. in the ceiling, it does not cause much problem.

In addition, in the latter case, since the interval between the lower surfaces of the grooves is wide, the interval between the fitting parts of the joint bar to be fitted becomes wide, making it impossible to obtain a firm fit, and the joint bar tends to come off easily. be. Moreover, there is no means for supporting the ceiling board on the wiring duct, and it is necessary to separately attach a fence.

The present invention attempts to solve these problems.

"Means for Solving the Problem" The present invention has a groove-shaped main part 1 provided with flanges 3, 3 on both edges, which bends outward along the longitudinal direction of the main part with a hook-shaped cross section. A pair of locking pieces 2, 2 are provided vertically, and locking uneven strips 4, 4 are provided on the lower edges of opposing surfaces of both locking pieces 2, 2, respectively. The outer end of the main frame is also placed within the range of the lower surface of the main part 1, and the interval between the outer ends of both the locking pieces 2, 2 is narrower than the width of the lower surface of the main part 1. A material A is formed, and a thin plate body 5 is provided corresponding to the lower surfaces of both the locking pieces 2, 2, and the plate body 5 is engaged with the engagement grooves 4, 4 on the inner surface of the plate body 5. A pair of engagement protrusions 6, 6 are provided protrudingly to form a joint bar I, and the joint bar I is connected to both of the above-mentioned locking pieces 2,
2 is removably fitted.

``Function'' Since the structure is as shown above, frame body B is constructed in the form of a lattice, for example, and fixed to the ceiling, and the locking pieces 2...
..., 2... are used to removably equip the ceiling plate H..., lighting equipment, etc., inside the frame main part 1.
Insert indoor wiring and various piping such as electrical outlets, telephone lines, TV antennas, HA equipment, etc.

Further, a necessary electric cord, telephone line, etc. is inserted between the pair of locking pieces 2, 2, and a joint bar I is fitted to close the opening.

"Example" The drawings show an embodiment of the invention.

In the illustrated example, a long main frame member A and a joint bar I are formed by extrusion molding of aluminum.

The main frame material A includes a pair of locking pieces 2 which are hook-shaped in cross section and bend outward from the bottom surface of a groove-shaped main part 1 having flanges 3 on both edges along the longitudinal direction of the main part. 2 is provided vertically, and engagement protrusions 4, 4 are provided on the lower edges of the opposing surfaces of both locking pieces 2, 2, respectively, and any outer ends of both locking pieces 2, 2 are connected to the main portion. 1, and both locking pieces 2,
The distance between the outer ends of the main part 2 is narrower than the width of the lower surface of the main part 1.

The joint bar I is provided with a thin plate 5 corresponding to the lower surfaces of both the locking pieces 2, 2, and has a pair of engagement members on the inner surface of the plate 5 that engage with the engagement grooves 4, 4. It is formed by protruding ridges 6, 6.

Then, the required system ceiling frame B, which is framed in a lattice shape using the main frame material A, is made and placed on the ceiling, and hanging bolts C and hangers D are attached to the ceiling slab.
It is connected and fixed to the frame support E suspended by the clips F using the flanges 3. In addition,
The connecting portion of the main frame members may be made using a metal fitting or may be welded.

In detail, a large number of ceiling plates H are provided to fit between the lattice meshes of the frame B, and the locking pieces 2 are provided, and hook-shaped latches G are attached to the periphery of these ceiling plates, and the latches are attached. The ceiling plate H is engaged with the locking piece 2... and fitted.
support. However, in the wall portion, a locking frame J similar to the locking piece 2 is provided and utilized.

Further, on the upper surface of the frame B, an electric cable branching unit K, a TV unit L, and a telephone unit M are provided at appropriate locations, and their wiring cables are housed in the groove-shaped main part 1. Connect the cable to the distribution board N, terminal board 0, etc. that leads to indoor wiring.

Between the pair of locking pieces 2, 2 of the frame B, insert the necessary electrical cords, telephone lines, etc. from the indoor side,
Then, a joint bar I cut appropriately to correspond to the frame body B is fitted between the locking pieces to close the groove.

"Effect of the invention" According to the invention, in the main frame material A, the pair of locking pieces 2, 2, which are hook-shaped in cross section and bent outward, are suspended from the lower surface of the groove-shaped main part 1. Since it is housed within the area of the lower surface of the part 1 and the distance between the two locking pieces 2, 2 is narrow, both the locking pieces 2, 2 can be secured to the main part during transportation, handling, etc. protected by 1,
There is little deformation or damage caused by external forces, it is possible to reduce inconveniences in installing ceiling panels and defects in appearance, and it is possible to reduce problems in fitting the joint bar 1, and
A rib effect can be obtained in the middle part of the main part 1.
Further, the joint bar 1 is provided with a thin plate 5 corresponding to the lower surfaces of both of the locking pieces 2, 2, and is engaged with the engaging grooves 4, 4 on the inner surface of the plate 5. Since the pair of engaging protrusions 6, 6 are provided protrudingly, the interval between the engaging protrusions 6, 6 can be narrowed, and therefore the so-called stiffness for fitting can be strengthened, making it difficult to come off. It can be done.

The main frame material A and the joint bar 1 can be conveniently used in the system ceiling, and it goes without saying that indoor wiring and various piping for lighting equipment, telephones, TV antennas, HA equipment, etc. can be inserted into the main part 1. ,
Indoors, electrical cords, telephone lines, etc. connected to an outlet can be arbitrarily inserted between the pair of locking pieces 2, 2 as required, so that the electrical cords, telephone lines, etc. that are being routed do not get in the way under your feet. In addition, the joint bar I has a pair of engaging protrusions 6,
6 and is engaged with the pair of engagement uneven strips 4, 4, so that the locking pieces 2, 2 can be accurately fitted and held, and furthermore, by mounting this joint bar I, Improves aesthetic appearance.
