Abstract

A multi-unit housing information and communication cable protection duct according to one embodiment of the present invention comprises: a rectangular tube duct in which an information and communication cable is piped into the interior of each household within the interior space, and an opening tube is formed on one side having an opening that exposes the interior space to the interior of each household, and is vertically erected to be embedded in a building wall so that the interior space is interconnected throughout the entire building; and a duct heat dissipation fan, which is a standing rectangular fan connected to a power source and fixedly installed at the center of the opening of the opening tube, which operates when the temperature detected by a temperature sensor is higher than a preset temperature to blow air from the interior of the household into the interior space to dissipate heat from the interior space. The device may further include a heat dissipation fan fixing section, which is fixedly installed in the opening of the opening pipe and supports the duct heat dissipation fan, and has a plurality of front vertical heat dissipation fins formed thereon that are vertically erected and protrude from the front side; wherein the duct heat dissipation fan comprises a rotating shaft, a blade that rotates by the rotation of the rotating shaft to generate wind, and a cover section that covers the blade to prevent the blade from detaching from the rotating shaft, and the cover section may further include a fire extinguishing unit that is disposed on the placement space and has fire extinguishing powder, wherein at least a portion of the center of the front side of the cover section is recessed to form a predetermined placement space.

Description

Information and communication cable protection duct of embedded apartment house The present invention relates to an information and communication cable protection duct for multi-unit housing, and more specifically, to an information and communication cable protection duct for multi-unit housing that facilitates the wiring of information and communication cables, allows for integrated connection and separation to facilitate repair work, and enables the extinguishing of fires in advance. Generally, as the population increases, residential space becomes relatively smaller, leading to an increase in multi-unit housing such as apartments. Since these apartments are fully equipped with all facilities inside and are very convenient to use, they have become a type of housing that most people want to live in. In the past, when constructing apartments, only electrical wiring was required. However, with the recent diversification and acceleration of media usage, it has become necessary to install various low-voltage wires other than electrical wires, such as telephone lines, high-speed internet dedicated lines, and CATV/MATV cables, when constructing apartments. To this end, the design involves providing a communication EPS room or pit on each floor and wiring using cable trays. However, since these communication EPS rooms or pits are very large with an area of about 13 x 07 m², this has caused the common area to be reduced, resulting in a narrower actual living space. Additionally, masonry and site management in the narrow space are difficult, unnecessary construction costs have increased, and piping installation from the telephone terminal box to the EPS room is difficult and expensive. Furthermore, there are many problems that may lead to defects as the floor piping passes through the bathroom floor. In addition, when construction is carried out without installing communication EPS rooms or pits, a large number of PVC conduits containing various wires are embedded in the frame. In such cases, not only is the installation of the conduits very difficult, but the structural strength is also weak, requiring separate rebar reinforcement. Furthermore, there is a risk of damage from anchors or drills after installation, and repairs are almost impossible if damaged, and there are problems such as high material and labor costs. In order to solve these conventional problems, Korean registered patent No. 10-2595522 B1 (October 25, 2023) discloses an embedded information and communication cable protection duct for multi-unit housing equipped with a heat dissipation function. The prior art invention is equipped with a duct heat dissipation fan having a temperature sensing sensor, a heat dissipation fan fixing heat dissipation unit having a vertical horizontal heat dissipation plate, a central vertical support plate, a central left and right vertical support plate, left and right end vertical support plates, and left and right handle bars, an elastic vertical heat dissipation plate having a horizontal fixing plate and a corrugated support heat dissipation plate, and a cable support heat dissipation unit having a cable support semicircular tube, a cable vertical contact plate, and a front heat dissipation plate. It facilitates wiring of information and communication cables through a withdrawal hole, allows for integrated assembly and separation for easier repair work, enables separate support of information and communication cables within the internal space of a cable protection duct, and effectively dissipates and cools the heat in the internal space transmitted through the elastic vertical heat dissipation plate using the airflow of the duct heat dissipation fan even during hot summers when the entire building is heated, thereby minimizing connection instability of information and communication cables. However, it has a problem in that it lacks a fire extinguishing function in the event of a fire occurring within the internal space of the protection duct. FIGS. 1 and FIGS. 2 are schematic diagrams for explaining the prior art referenced in deriving the present invention. FIG. 3 is a schematic cross-sectional view illustrating a heat dissipation unit of an information and communication cable protection duct for a multi-unit housing according to the present invention. FIG. 4 is a schematic front view illustrating the cover portion of the information and communication cable protection duct of a multi-unit housing according to the present invention. Specific embodiments of the present invention will be described in detail below with reference to the drawings. However, the concept of the present invention is not limited to the presented embodiments. Those skilled in the art who understand the concept of the present invention may easily propose other inventions that are inferior or other embodiments included within the scope of the concept of the present invention by adding, changing, or deleting other components within the same scop
