Description

Mounting and Fixing Devices for Flexible Joint for Sprinkler}

The present invention is fast and easy even in the low ceiling space of buildings such as general buildings, factories and apartments in fixing the connector of the flexible joint set that connects the sprinkler head installed in the building with the branch pipe in the middle of the fire. The present invention relates to a fastening device that can effectively install a connector of a sprinkler flexible joint set at the proper position and the correct height for the purpose of economical and precise construction.

Today, the use of flexible joints for sprinklers has become commonplace in commercial buildings due to their ease of operation and excellent construction quality. The space between the ceiling and the slab is wide and there are hangings available on the ceiling, such as C-channel or M-bar, so that the brackets can be secured to each other across the square bars at the appropriate positions. The installation method is fixed. This installation method has largely replaced the existing steel pipe construction method, which has hardly changed for a long time due to many advantages such as ease of construction, short construction time, and excellent construction quality.

Although the construction method by the flexible joint has many advantages, the steel pipe piping method is still adhered to in the low ceiling buildings. The reason is that there is no useful use such as C-channel or M-bar which can effectively fix the flexible joint for building structure or use, but steel pipe piping method is inevitably required despite such inefficiency. On the other hand, the only available method of using a wooden mounting bar on the ceiling of the apartment has been attempted, but it is rarely used due to the inefficiency of process management due to the separate operation of the discontinued license of interior and fire fighting. Therefore, in order to use an excellent flexible joint construction method, an appropriate fixing device had to be developed.

The present invention is intended to achieve high construction quality while reducing air construction and construction cost through simple and simple construction by adopting a flexible joint even in a building with low ceiling space in view of the above-described conventional problems.

There are important considerations for the convenient use of sprinkler flexible joints in low ceiling structures. Unlike commercial buildings with high ceiling spaces (averages above 50cm), low ceilings should have short fixtures due to low ceiling spaces between the ceiling and slabs (average of 10-25cm). In the case of the apartment, there is no use that the fire-fighting equipment company can use for fixing other than the ceiling-mounted wooden bar, which is a part of the interior discontinued license, so the fixing bracket can be attached to the ceiling (990 of FIG. 15) and the slab (960). Should be available. In order to accommodate a wide range of elasticity in the flexible joint construction for sprinkler of the fire fighter's license, which is later constructed, the error of the ceiling construction using the wooden mounting bar installed by the interior discontinuity business operator must be equipped with efficient height adjustment function. The sprinkler hye should also have a structure capable of adjusting the height for the correct construction through the adjustment tool 980 for the adjustment bolt as a narrow hole (970 '970) for the cover (aka' king '). And when the sprinkler head is attached and detached, it should be equipped with a solid structure that can prevent left and right side shake and distortion so that there is no problem in the work practices of the field workers.

Only when these important and basic requirements can be solved can the convenience of flexible joints be applied in the field. Therefore, the present invention relates to a fixing device for the connector of the flexible joint set for the sprinkler to solve these technical problems and to use conveniently in the construction site.
