Description

Duct assembly integrated with wiring

The present invention relates to a duct assembly having a piping wiring mechanism and a general-purpose bracket connected thereto as an integral body.

During construction, wiring works such as electric lines and communication lines are performed. When wiring, such as an electric or communication line, is exposed to the outside, there is a risk of a safety accident and the aesthetics are not good. As a method for this, a piping wiring mechanism or a duct is used.

The piping and wiring mechanism is constructed by embedding the piping and wiring mechanism during construction of walls, floors, ceiling slabs, columns, etc. and then pouring concrete. The piping wiring apparatus used herein includes piping such as PVC or corrugated pipe to be buried, various wiring such as electric wires, communication lines, telephone lines, data cables, etc. located in such piping, and wiring apparatus having power supply fittings, switches, etc. necessary for this. means box.

Although it is possible to construct the piping and wiring equipment by embedding it, when the PC (pre-cast) method is used, or when the embedding of the piping and wiring mechanism itself is not possible due to various reasons such as the placement of the embedded structure, the location of the structure, and the difficulty of construction There is a problem that there is often In particular, since the recent PC method is widely used, the use of piping and wiring mechanisms is very limited.

A method of using a pipe or a wiring duct without a pipe wiring device is also used.

The pipe is formed of galvanized steel, and the pipe wraps and protects the wiring. The size of the pipe itself is not large, and it is possible to adjust the angle relatively freely, so it has excellent workability. However, the durability of the pipe itself is not high, so the stability is low, disassembly/reassembly for branching or maintenance is difficult, and it has low durability and poor aesthetics because it is vulnerable to external shock. A separate bracket for hanging the pipe from the ceiling slab, etc. and a separate bracket for installing the instrument are required, respectively.

The wiring duct also has a structure that wraps and protects wiring like a pipe, but is larger than a pipe and has relatively high durability because it is made of aluminum or the like. A general wiring duct has a U-shaped cross-section and is elongated, and a detachable cover is provided on the top, and openings of a certain size are continuously formed on the left and right sides so that the wiring can be discharged to the outside. It is made of PVC material so that it can bend easily or part of the left and right side walls can be removed. Various wiring is housed in the wiring duct, and when a part of wiring needs to be branched to the outside, or when wiring equipment needs to be installed, let the wiring pass through the opening on the side or remove a part of the side of the wiring duct and separate the wiring. is branched

However, first, a plurality of openings are formed in the left and right sides in consideration of the wiring branching in the wiring duct, and a large amount of foreign substances flows in through these openings. In particular, when the wiring duct is installed in a dusty space such as an underground parking lot, there is a risk of fire due to inflowing dust or foreign substances. If moisture enters, it may cause malfunction.

Second, in a place such as an underground parking lot, the wiring duct is installed in a way that it is suspended from a ceiling slab or beam (see FIG. 9), and in this process, a separate bracket to support the wiring duct is additionally required. The workability is lowered as much as the required bracket.

Third, using the branched wiring from the wiring duct, sensors, lighting equipment, CCTV, repeaters, speakers, etc. can be installed, since these devices are installed to be hung from the ceiling structure in a place separate from the duct. A different type of bracket is required from the bracket for supporting the ceiling slab. The difficulty of installing them is high, and it takes a lot of manpower and time.

The duct assembly according to the present invention includes a duct 100 and a bracket 300 for an appliance, and further includes a bracket 200 for fixing in some cases.

The duct 100 is a space in which wiring L, such as an electric line, a communication line, a telephone line, and a data cable, is mounted inside.

The duct 100 is made of a plurality of unit parts so that a plurality of them can be connected. A method of connecting them will be described later.

Of course, there is no limit to the number of ducts 100 to be connected. Since the number is not limited and can be expanded as much as the installer wants, it can be freely adopted according to the installation space. As an example for description, FIG. 2 shows a form in which seven ducts 100 are connected, FIG. 3 is two, and FIG. 5 shows four connected forms.

Although not shown, it is possible to employ a duct for a corner bent by 90 degrees, or a duct having a bent shape that is bent at any other angle. The structure of the duct for the corner is not significantly different from the general duct 100 to be described later, and only the duct casing 110 may be bent, for example, in an L-shape.

The fixing bracket 200 is an integral part for hanging the duct 100 on an upper structure such as a ceiling slab. The fixing bracket 200 is installed only on the part that needs to be hung on the upper structure, and a plurality of brackets may be provided.

A wiring opening 390 may be provided on the upper surface, the lower surface, or both the upper and lower surfaces of the bracket 300 for the appliance. Although shown as being provided on both the upper surface and the lower surface in the drawing, the modification is possible, for example, the wiring opening 390 may be provided on the side surface. The wiring opening 390 is a portion where the wiring L that passes through the duct 100 is branched and discharged to the outside of the duct assembly. Accordingly, if the device D such as direct lighting is attached to the wiring opening 390 , the wiring L is not exposed to the outside at all and is directly connected to the device D (refer to FIG. 2 ).

The bracket 300 for the appliance has an outer wall body 310 that forms an opening (A) for the duct in the front and rear along the moving direction of the duct 100 . Here, the size of the opening (A) for the duct corresponds to the size of the outer surface of the duct 100 in the proceeding direction (lower right direction in FIG. 2) of the duct 100, so that the duct 100 is firmly secured by the outer wall 310 It is supported and prevents the wiring L from being exposed to the outside. 1 and 2, the duct 100 is coupled to the opening (A) for the duct is shown.

A wiring space (B) is formed between the outside of the duct 100 and the inside of the bracket 300 for the instrument, and the wiring (L) proceeds here. The wiring space B communicates with the open upper side of the duct 100 . After the wiring (L), which was traveling on the duct (100), is branched, it enters the wiring space (B). Since the wiring opening 390 is formed in the wiring space B, the branched wiring L is discharged to the outside (refer to FIG. 8).

On the other hand, the bracket 300 for a mechanism according to the first embodiment of the present invention is formed of two parts of the same shape, thereby increasing manufacturing and construction convenience and lowering the unit cost. 7 shows one individual part. In this case, the protruding connector 320 is positioned at one end of each part, and the connector groove 340 into which the connector 320 is inserted is positioned at the other end, so that the installer can easily fasten or release it, It improves constructability and is convenient to dismantle and reassemble for maintenance.

According to the construction plan, check the part where the wiring (L) is to be branched in the duct 100, remove the cover 120 of the corresponding part, and check the part where the bracket 300 for the appliance is to be located.

By using the fixing member 280, the fixing bracket 200 is mounted on an upper structure such as a ceiling slab. With the mounting of the fixing bracket 200, the duct 100 is also mounted and suspended.

The wiring L runs through the inside of the duct 100 . The installer can easily work while detaching the cover 120 .

The wiring L is branched at the previously confirmed branching portion. At the same time, the bracket 300 for the appliance is mounted on the corresponding part and the branched wiring L is discharged to the outside through the wiring opening 390 . As shown in Figure 7, since it can be divided into two parts, it is possible to easily mount the bracket 300 for the instrument even in a state in which the duct 100 is fixed to the upper structure.

When the wiring L is branched, it will be formed as illustrated in FIG. 8 . That is, the wiring (L) proceeding through the duct 100, the cover 120 is removed and discharged to the upper side of the open duct 100, the space between the bracket 300 and the duct 100 for the instrument. After extending downward through the wiring space (B), it is discharged through the wiring opening (390). Although not shown, even when the wiring L is to be discharged to the upper side of the bracket 300 for the appliance, it passes through the upper side of the duct 100 and the wiring space B in the same manner as the upper part of the bracket 300 for the appliance. It may be discharged through the wiring opening 390 .

Next, while mounting the appliance (D) to the appliance bracket 300, the branched wiring (L) is connected to the appliance (D) such as a repeater, a sensor, a CCTV, lighting, and a speaker. With this structure, the wiring L is not exposed to the outside.
