Problems solved by technology

Another important disadvantage of this system lies in the fact that the connection height is not variable, since it is predetermined in a fixed manner by the socket height, fittings and connections
That is, the thread options are not compatible with different sizes, and different sprinkler connection boxes must be manufactured for installation, so that for each sprinkler, there is a corresponding connection option, which causes high costs in part development and logistics. cost

Embodiment Construction

[0049] figure 1 Shown is the sprinkler connection box 1 as received when delivered pre-assembled to the installation engineer, already assembled ready to be installed in a suspended ceiling. All the installation engineer needs to do is to hammer the sprinkler connection box 1 to the cladding panel using fastening means 4, preferably nails, so that the sprinkler connection box 1 is positioned such that it is fixed in all directions. The engineer must then connect the transition piece 6 to the sprinkler pipe 23, possibly by means of a welded joint. Usually, multiple sprinkler connection boxes 1 are connected to the sprinkler pipes, so the simple installation saves a lot of assembly time. Once the sprinkler connection box 1 has been connected, a seal test can be performed directly to test the tightness of the system's seal. Since the plug 5 ensuring the tightness of the seal is already pre-assembled in the sprinkler connection box 1, the installation engineer does not need (as ...

Abstract

The device i.e. sprinkler connection box (1), has a connection piece (2) made of metallic material e.g. brass or red bronze, and a housing (3) including a fastener (4) i.e. pin, which enables positioning and fastening on a surface. A sealing stopper (5) enables leakage tests and is made of plastic. The piece, the housing, the fastener, the stopper and a transfer piece are premounted. The box is connected with a sprinkler line and fastened to a formwork plate. The stopper includes a stage (9) sealed with a bevel (10) in the connection piece in a screwed-in condition. An independent claim is also included for a method for attaching connection of a sprinkler in a ceiling.

Description

technical field [0001] The invention relates to a device for connecting a sprinkler, in particular a sprinkler connection box, and to a method for installing it in a suspended ceiling, comprising: a connecting piece made of metallic material; having fastening means The housing, the fastening means making it possible to position it and fix it to a surface; the sealing plug, making it possible to perform a leak test; and the transition piece. Background technique [0002] The prior art discloses sprinkler connection boxes which are assembled during the installation and laying of the piping of the entire sprinkler system, which takes a considerable amount of time. DE 10 2009 041 415 A1 discloses a method and a device in which, during installation of a sprinkler system, centering elements are used to screw the bell-shaped parts to the respective pipe ends. During this time, the bell part can still additionally be positioned with nails. The disadvantage of this system is the co...
