Description

  The present invention relates to a system ceiling, and more particularly to a system ceiling in which cables can be easily laid.

  The usual “conventional ceiling” is a type in which lighting equipment, air-conditioning anemo, etc. are embedded in the rock face plate. A rock surface board is an uneven incombustible board, and in recent years it has become a global environmental problem because it cannot be burned or discarded.

  The so-called “system ceiling” found in buildings in recent years is a type in which a parallel aluminum bar is provided with a slit inlet, etc., and a lighting fixture, an air conditioner, etc. are provided between the parallel aluminum bars.

  Recently, a type in which a 600-square ceiling panel (made of aluminum) is arranged and necessary appliances are embedded in a part of the panel has appeared.

  In the process of development from “conventional ceiling” to “system ceiling”, the transfer of ceiling equipment should be reduced when modular partitioning of the steel partition (holes in the ceiling plate) is made under the ceiling (modularization). The purpose was to reduce ceiling materials that had holes and had to be discarded.

  By the way, the existing wiring method for the back of the ceiling is to hang and wire a cable rack for electrical installation. The wiring method did not work as usual even when it became the ceiling of the system. The wiring method was carried out by the system ceiling and another contractor, and it was constructed regardless of the system ceiling.

  In recent years, office automation has progressed and many electronic devices such as personal computers have been installed in offices. Along with this, it is necessary to lay a large number of power cables, LAN cables, etc., and the amount of cables is enormous. Since conventional system ceilings did not give consideration to cable laying, various problems occurred after the installation. For example, if there is no inspection port on the system ceiling, wiring is impossible. To suspend a cable rack, the ceiling plate must be broken.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a system ceiling in which a cable can be easily laid by providing the system ceiling itself with a cable storage function. The cable can be laid in any route, and the cable can be lowered to the floor with a pillar at a desired location. Since the ceiling plate of the ceiling of the system can be easily removed, the inspection port is no longer necessary.

In order to solve the above problems, the present invention is provided with a plurality of bar-shaped ceiling members assembled in a lattice shape, a fixing member fixed to a housing on one side, and at least a part of the plurality of ceiling members on the other side. In a system ceiling provided with a support fitting that holds a plurality of ceiling members provided with suspension fittings fitted to the
The cross section of the ceiling member has a groove shape, and the upper end on both sides is folded at an acute angle to form a folded portion,
The shape of the hanging bracket is an inverted T-shape, provided with extensions extending upward from both ends of the inverted T-shape, the ends thereof having acute angles, and the ends can be fitted to the folded portion of the ceiling member In addition, a notch groove was provided between the central portion of the suspension fitting and the extension portion.
Accordingly, the cable can be stored in the groove-shaped portion of the ceiling member, and the cable can be passed through the notch groove of the hanging bracket, and the cable can be laid through any path of the lattice-shaped ceiling member. It became so. It is no longer necessary to install a cable rack separately from the system ceiling.

  Preferably, the cross-section of the ceiling member is H-shaped, the cable is stored in the upper part, the device including the lighting is stored in the lower part, and the opening is formed in the part separating the upper side and the lower side of the ceiling member Is provided. A cable can be led to the device through the opening.

  Preferably, a column having a cross-shaped cross section is provided at an intersection of the ceiling member, a cable is guided to the column through an opening provided in the intersection, and the cable is laid along the column. The cable can be lowered to the position of the floor or desk through the pillar. It is no longer necessary to lay wiring under the floor.

  According to the present invention, the cable is housed in the groove-shaped portion of the ceiling member and the cable can be passed through the notch groove of the hanging bracket, so that the system ceiling itself has a cable housing function, and as a result, the cable Can now be laid easily.

Embodiments of the present invention will be described with reference to the drawings.
