Description

Sprinkler protective cover assembly {SPRINKLER PROTECTIVE COVER ASSEMBLY}

The present invention relates to a sprinkler protection cover assembly that can prevent short circuits in electrical/electronic devices and communication pipes during the removal or installation of sprinkler equipment including sprinkler flexible tubes.

Generally, sprinkler equipment is installed inside clean rooms such as semiconductor factories to enable early extinguishment in the event of a fire.

Recently, rapid changes have occurred in the semiconductor market, and the subsequent construction changes and frequent water leaks due to old sprinklers have led to frequent sprinkler removal and reinstallation.

Specifically, during the removal and reinstallation of the sprinkler, parts that cannot be seen with the naked eye, such as wiring in the covers of various electrical devices including lights, may be damaged (dents, peeling, etc.). There are concerns that safety accidents and technical accidents may occur due to this.

Additionally, there is a problem that accidents may occur due to changes in construction and management companies or different work methods of workers during maintenance of the sprinkler.

< First embodiment >

Figure 1 is a perspective view of a cover assembly for sprinkler protection according to a first embodiment of the present invention, and Figure 2 is an exploded perspective view of Figure 1.

Referring to FIG. 1, the sprinkler protection cover assembly 100 according to the first preferred embodiment of the present invention may include a joint member 110, a protective cover 120, and a reducing nipple 130.

A detailed description of the configuration of the present invention is as follows.

First, the joint member 110 is coupled to the space between the mold bars 10 constituting the ceiling structure, and this joint member 110 may be provided with a coupling hole 111 penetrating in the vertical direction. .

For reference, a plurality of the mold bars 10 may form a grid-shaped frame so as to support and secure the ceiling structure to which sprinklers are installed.

In this case, an upper coupling groove 11 may be formed on the upper surface of the mold bar 10 along the longitudinal direction so that various structures, which will be described later, can be fixed through fastening members.

More specifically, the joint member 110 is preferably installed at a point where the mold bars 10 intersect to enable robust assembly on the ceiling structure. Accordingly, the joint member 110 may be formed in a cross (+) shape when the body is viewed in plan so that it can be coupled to correspond to the space where the mold bars 10 intersect. Of course, it is not limited to this, and when installed on a straight part of the mold bar 10 rather than an intersection point of the mold bar 10, the body may be changed to a straight (-) shape. In the present invention, an example where the joint member 110 is formed in a cross shape will be shown and described.

In this case, the joint member 110 may be provided with a corresponding fitting protrusion 113 on its outer surface so that it can be fitted into the fitting hole 13 provided on the opposing surface between the mold bars 10. Accordingly, robust assembly of the mold bar 10 and the joint member 110 may be possible.

Referring to FIG. 2, the protective cover 120 is coupled within the coupling hole 111 of the joint member 110, and is a hollow pipe body of a length corresponding to the insertion portion 131 of the reducing nipple 130, which will be described later. It can be formed in a (tunnel type) shape. The protective cover 120 is a sprinkler equipment 1 (see FIG. 3) including a sprinkler flexible tube installed via a reducing nipple 130, which will be described later (hereinafter abbreviated as 'sprinkler'). plays a role in protecting the body. In other words, the protective cover 120 can prevent short circuits in electrical/electronic devices (lights, sensors, APs, etc.) and communication pipes that may occur during removal or installation of the sprinkler 1.

Specifically, the protective cover 120 according to the first embodiment of the present invention includes an upper pipe body 121 screwed to the inner upper side of the coupling hole 111, and an upper pipe body ( 121) and a lower pipe body 123 screwed on the same axis.

That is, the protective cover 120 may be formed as a single tube body and fitted into the coupling hole 111 of the joint member 110. However, if the protective cover 120 is formed as a single tube body, the coupling hole 111 ) A separate fixing means is required to secure the protective cover 120 fitted within. Accordingly, in the first embodiment of the present invention, the protective cover 120 is divided into an upper pipe body 121 and a lower pipe body 123, and these are formed on and below the coupling hole 111 of the joint member 110. Each can be configured by screwing together.

Referring to FIG. 3, the reducing nipple 130 is fitted on the central axis within the protective cover 120 and is fixed on both sides to the upper part of the mold bar 10. Sprinklers 1 may be assembled inside.

Specifically, the reducing nipple 130 is formed along the longitudinal direction of the mold bar 10 on both sides of the upper part of the insertion part 131 of the hollow tube body assembled inside the protective cover 120. It is formed to extend integrally and may include a fixing part 133 fixed to the upper coupling groove 11 of the mold bar 10 via a fastening member 135.

Referring to Figure 4, the sprinkler protection cover assembly 100' according to the second embodiment of the present invention includes a joint member 110 coupled to the space between the mold bars 10 constituting the ceiling structure, and a reducing The structure of the nipple 130 is the same as that of the first embodiment, and the structure of the protective cover 120' coupled to the coupling hole 111 of the joint member 110 is similar to the protective cover 120 of the first embodiment. It can be applied differently.

When described in detail with reference to FIG. 5, the protective cover 120' according to the second embodiment of the present invention may be formed as one piece without being divided into upper and lower parts. This protective cover 120' includes an insertion tube body 125 formed to a predetermined length so as to be inserted into the coupling hole 111 of the joint member 110, and an insertion tube body 125 on both upper sides of the insertion tube body 125. It is formed to extend integrally along the longitudinal direction of the mold bar 10 and is provided with a first through hole 127a so that it can be fixed to the upper coupling groove 11 of the mold bar 10 via a fastening member 129. It may include a fixing bar (127).

In this case, the fastening member 129 penetrates the fixing bar 127 so that the reducing nipple 130 can be coupled to the upper coupling groove 11 of the mold bar 10 via the fastening member 129. A second through hole 127b may be provided.

In this case, the fixing bar 127 of the protective cover 120' may be formed longer than the fixing part 133 of the reducing nipple 130. In addition, the first and second through holes 127a and 127b of the fixing bar 127 may be formed as long holes along the longitudinal direction of the coupling groove of the mold bar 10 to facilitate fastening of the fastening member.

Accordingly, as shown in FIG. 6, it is possible to firmly fix the protective cover 120' and the reducing nipple 130 together in the upper coupling groove 11 of the mold bar 10.

Meanwhile, the protective covers 120 and 120' according to the first and second embodiments described above are preferably formed to have a thickness of 1 to 2 mm or more to withstand external impact, and must be made of non-combustible materials.

The sprinkler protection cover assembly (100) (100') according to the first and second embodiments of the present invention as described above includes a protective cover (120) (120') capable of protecting the sprinkler (1) installed on the ceiling structure. By applying it, it is possible to minimize human and material accidents due to short circuit accidents, which have been a chronic occurrence when removing or installing sprinklers (1), and maintenance of sprinklers is easy.

In the above, the present invention has been shown and described with reference to specific specific embodiments, but the present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the technical spirit of the present invention.
