Abstract

The present invention is a corrugated pipe having a bent pipe coupled to the digestive main pipe and a slip nut connecting the bent pipe and the nipple and a bracket for fixing the nipple in the ceiling are installed on the tex, which is a ceiling finish by the angle bars. It relates to a sprinkler control device capable of adjusting the height of the fire extinguishing by inducing the fire extinguishing water flowing from the fire main pipe to the sprinkler (sprinkler).

Specifically, the nipple is formed by sliding and screwing the nipple so as to move along the guide groove formed in the bracket, and rotating the adjusting device mounted in the bracket so that the adjusting device is rotated along the contact surface formed in the nipple screwing bracket. It is an up and down movement around the center, which is more convenient in use than the device for fixing the nipple (fire extinguishing outlet or sprinkler reducer) to the bracket by conventionally one side, and pushes each bar to fix the nipple to the bracket. The nipple is fixed by the guide groove and the adjustment hole formed in the bracket is to have the advantage that it is easy to improve the workability and assembly and replacement.

The present invention utilizes a bent pipe coupled to the fire main pipe within the ceiling and the height of the ceiling tex by using a control device mounted on the nipple and bracket to extinguish the extinguishing water flowing into the sprinkler in case of fire. The present invention relates to a height adjusting device for extinguishing piping that can be adjusted.

Generally, sprinkler is fired because the upper part of the building, that is, the metal of the sprinkler head attached to the ceiling or the wall is melted by the heat during the fire, and the water of the sprinkler is removed and the pressurized water is sprayed from the head before the ignition point. It is used for general fires such as wood, paper, or fabrics. It is used for general fires such as wood, paper, and fabrics. It is effective for liquid fires because it emits water in a spray form. It is suitable as a fire extinguishing system with a lot of combustibles and a lot of people, and it can be expected to be automatic fire extinguishing at night. The scope of application is very wide, and it usually operates at 67 ~ 180 ℃. About quantity depends on building type and degree of interior It is defined by the Fire Services Act.

In general, the purpose of the present invention is to be used for the early fire extinguishing in office buildings or factory buildings, and the space inside the ceiling is relatively wider than the general houses or apartments, so that the branched branches are installed in the main pipe piped into the ceiling.

Looking at the representative technical literature to which the present invention belongs, there is a Republic of Korea Utility Model Registration No. 0375641 "Spring cooler extinguishing water outlet fixing bracket" and the Utility Model Registration No. 0392716 "Spring Crusher reducer mounting device".

The Republic of Korea Utility Model Registration No. 0375641 "Spring Cooler Extinguishing Water Outlet Fixing Bracket" relates to a fixing bracket for fixing the extinguishing water outlet to be fixed to the ceiling of a building and fastened with a sprinkler for automatic suppression in case of fire. A bracket having an upper opening and a lower fitting hole penetrating the center of the upper and lower wings so that the contact surface of the extinguishing water outlet is fitted into the 'c' shape having an opening so as to be fitted with a square support tube; A fastening bolt organically fastened to the fastening hole penetrated to the side of the bracket and close to the support tube to press the contact surface of the extinguishing water outlet; The side is formed in a '⊃' shape, the bracket is welded to the inside of the upper / lower wing front, it is composed of the auxiliary bracket to fix the upper / lower wings are separated or moved by the external impact.

And in the case of the Republic of Korea Utility Model Registration No. 0392716 "spring sprinkler reducer mounting device", the sprinkler reducer is inserted into the fixing hole of the fixing bracket disposed on the reducer support, and the butterfly bolt in the screw hole formed in the middle fastening plate of the fixing bracket In the sprinkler reducer mounting apparatus in which the octagonal outer circumferential surface of the sprinkler reducer is pressed and fixed between the reducer support and the outer contact portion of the fixing hole formed in the fixing bracket, the outer contact portion of the fixing hole formed in the fixing bracket is Five sides of the octagonal outer circumferential surface of the sprinkler reducer are formed to be in contact with each other. Pressed into contact It will be generated.

As described above, both conventional designs have a nipple (digestion outlet and sprinkler reducer) directly contacting a part of a bracket, and each bar (support pipe and support) is fixed by pushing each bar in the form of pressing and fixing the nipple. Since the tight coupling state of the nipple and the bracket is made according to the fastening state of the bolt and the butterfly bolt, when the fastening state of the fastening bolt and the butterfly bolt is loosened, the nipple flows between the upper / lower hole of the bracket and the fixing hole. Due to this, the downward direction of the sprinkler mounted on the end of the nipple is changed, so that the fire sprinkler's fire extinguishing range may be changed.

In order to overcome this problem, in the present invention, a slide part and a screw part are formed on the nipple to be moved along the guide groove formed in the bracket, and the control part is formed along the contact surface formed on the nipple screw part by rotating the adjusting part mounted in the bracket. The nipple can be moved up and down about the bracket by rotating, and it is more convenient to use than the device that fixes the nipple (digestion outlet or sprinkler reducer) to the bracket by inserting each bar to one side of the conventional one and pushes the nipple to the bracket by pushing each bar. It is to provide a height control device for the digestive pipe that is improved in workability and easy to assemble and replace by fixing the nipple by the guide groove and the adjustment hole formed in the bracket rather than the form fixed by pressing.
