Description

[Detailed Description of the Invention] The present invention is a spot-type sensing device for automatic fire alarm equipment that is installed in the ceiling of a theater, public hall, etc., and a lighting device for electrical equipment that is installed in a place where appearance is not a concern, such as an electrical room or machine room. ,
Other methods for installing high-place appliances inside buildings, such as speakers, that can be installed in high places without the need for scaffolding, and that allow for easy installation and replacement of appliances even after construction is complete. It is.

Conventionally, in this type of appliance installation method, a box is embedded or exposed in the body of the appliance mounting surface, and the required appliances are attached to the box.

Therefore, if the frame is existing due to renovation work, etc., the box will be exposed on the surface of the frame, and anchoring will be required for installation.Scaffolding will be required when installing the box or installing or replacing equipment. do.

The anchor driving may damage electrical conduits etc. buried in the building frame, the waterproof layer in the case of a roof, and even the building block itself in some cases.

The present invention has been proposed in order to eliminate such defects, and is intended to improve the performance of equipment that should be installed in high places, such as spot-type sensing equipment for automatic fire alarm equipment, lighting equipment for electrical equipment, speakers, etc. It is characterized in that it is attached in advance to the tip of a mounting rod, and then the mounting rod is attached to a hanging bolt for suspending a high-altitude building installed on the ceiling of a building and fastened to the hanging bolt via a tightening fitting. This relates to the method for installing equipment at high places in buildings.

In the present invention, as described above, the mounting rod to which the equipment to be installed at a high place is attached is installed at a high height such as a ceiling base suspended from the ceiling of a building via a hanging bolt or a catwalk in a theater or the like. Since it is attached to the hanging bolt on the building part and fastened through the fastening metal fittings, there is no need for a box for attaching equipment and an anchor material for anchoring the box to the building frame as in the past. without the need for
Therefore, there is no need to damage the building frame or waterproof layer.

In addition, since the installation work of the hanging bolt of the mounting rod is carried out on the above-mentioned high-place construction part, the work can be carried out safely without taking an unreasonable posture, and even if the equipment is installed at a high place, scaffolding is not required. Therefore, there is no need for people to transport, assemble, dismantle, relocate, or remove the scaffolding materials, which saves labor and construction costs.In addition, work safety is improved because work at heights on the scaffolding is avoided. Increased.

Furthermore, since the mounting rod is fastened to the hanging bolt via a tightening fitting, the work is simple and does not require skilled workers, and repair and replacement are easy.

Furthermore, since this method uses fastening metal fittings and does not use welding flame, it is suitable for work in the ceiling where dust accumulates and the use of flame is strictly prohibited.

Note that this method is not limited to renovation work, but can be implemented in new construction work where the ceiling is high and appliances must be placed above the ceiling, once the hanging bolts for the ceiling base have been installed. In addition, the equipment can be easily and quickly installed even before ceiling installation, and in both cases, the scaffolding for ceiling construction can also be used as a scaffolding for installing equipment, and it is possible to install equipment easily and quickly before installing the ceiling. It is possible to omit extra scaffolding for installation, and it also includes inserts for installing equipment,
Anchors and welding are not required.

In addition, when adding equipment such as lighting equipment and speakers later, it is difficult to secure a working space when installing the equipment, such as in an electrical room where high-voltage live parts are located close to each other, or in a mechanical room where piping ducts are crowded. In this case, the wall surface is used to secure the mounting rod to which the appliance is attached by bolting with a hole-in anchor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An illustrated embodiment in which the present invention is applied to a case where a smoke detector of a fire alarm system is installed in a theater or the like will be described below.

In Figure 1, A is the large hall on the upper floor, B is the small hall on the lower floor, 1 and 2 are the seats in large hall A, 3 is the orchestra bit, 4 is the stage in the large hall, 5 is the abyss, 6 is the grape trellis, 7 is the smoke outlet, 8 is the audience seats in small hall B, and 9 is the small hall stage.

Further, a catwalk 12 is suspended from the ceiling 10 via hanging bolts 11.

In the figure, 13 is the lower catwalk, 14 is the ceiling lighting section,
15 is a spot chamber.

Reference numeral 16 denotes a mounting rod made of a steel material with a grooved cross section as shown in FIGS. 2 to 6, and a horizontal mounting plate 17 is fixed to the distal end web of the mounting rod by welding or the like.

Then, the smoke detector 18 is attached to the horizontal mounting plate 17 in advance.

In the figure, 19 is a screw hole for mounting the smoke detector 18.

The attachment of the smoke detector 18 to the mounting rod 16 may be carried out in a safe place, and the attachment rod 16 with the smoke detector 18 attached thereto may be carried onto the catwalk 12.

Then, as described above, attach the mounting rod 16 of the smoke detector 18 to the hanging bolt 11 on the catwalk 12, hold the U-bolts 20 at multiple locations at the lower part of the hanging bolt 11, and Attach the leg pieces on both sides of the bolt 20 to the rod 16
The smoke detector 18 is installed on the ceiling by inserting the smoke detector into a pair of left and right through holes 21 bored in the web of the smoke detector, screwing and tightening the nut 22, and fixing the mounting rod 16 to the hanging bolt 11. be.

Note that the wiring 23 of the smoke detector 18 is tied to the hanging bolt 11.

The work of installing the smoke detector 18 using the mounting rod 16 is carried out on the catwalk 12.
The work can be done safely by hanging a lifeline on the handrail, making scaffolding and protective nets unnecessary.

The smoke detector 1B arranged at a predetermined position as described above can be removed after installation by releasing the fastening between the mounting rod 16 and the hanging bolt 11 by the U-bolt 20 and removing the mounting rod 16 from the hanging bolt 11. Maintenance and inspection such as repair and replacement of the equipment can be easily performed.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and may be modified in various designs without departing from the spirit of the present invention. be.
