Description

Safety rail for building with evacuation function {Safety rail for building with evacuation function}

The present invention relates to a safety railing for construction having an evacuation function, and more particularly, a homeowner residing on the upper floor of a building can easily and quickly evacuate to a veranda railing on the lower floor by means of a railing evacuation slide and left and right guide front and rear vertical rails. Since there are no products or electronic parts at all, there is no worry of malfunction or deformation due to water in the rainy season, which greatly reduces maintenance costs, and in an actual emergency, residents can evacuate to the lower floor smoothly and quickly without fear of malfunction or malfunction, preventing human damage. It relates to a safety railing for construction equipped with an evacuation function that can be prevented in advance.

In general, a balcony is a space configured for the purpose of space utilization and aesthetic improvement of high-rise buildings such as apartments. These balconies are equipped with handrails using pipes to prevent safety accidents such as falls of people or objects.

On the other hand, in the case of apartments, since there is no separate means of emergency escape under the Fire Act, in case of an emergency such as a fire, use the entrance or balcony, but when using the balcony, use special personnel and equipment such as an elevated ladder. Emergency evacuation was possible.

Therefore, a technology that can be used by converting a handrail provided on a balcony of an apartment into an emergency ladder in case of an emergency, such as a fire, has been disclosed in various forms. That is, conventionally, both ends of a handrail frame composed of an upper and lower horizontal frame and a plurality of vertical frames connecting the upper and lower horizontal frames are connected to a balcony wall with a detachable joint, and the lower part of one side is connected to a rotating shaft to separate the joint, and then the handrail frame Separated from the balcony wall, it can be used as an emergency ladder to evacuate to the lower balcony by rotating it downward using the rotation shaft at the lower part of one side.

However, since the handrail frame of the above emergency ladder is a heavy body, it is very inconvenient to lift and rotate the ladder as a whole in a state in which the joint is separated.

Accordingly, as a countermeasure for improving the above-mentioned problems in the prior art, a method using a driving means for automatically operating the rotation operation of the handrail frame through power supply has been disclosed.

However, in this case, there was a problem in that the electric wire was disconnected due to the high temperature heat appearing in the event of a fire or the coating of the electric wire was melted and short-circuited.

In order to solve this problem, "in the building safety handrail installed in the opening 10 of a building prepared to install a window and having a fall prevention function and an evacuation function used as a means for evacuating in an emergency, the evacuation function The safety handrail 100 for construction is a handrail frame 110 in which a plurality of perforated boards 113 are fixed at an angle at a predetermined angle in a rectangular frame body 111; the end of the handrail frame 110 is placed on the side of the opening 10 of the lower floor.

A second drive motor (M2) is installed, and is axially coupled with the second drive motor (M2) between the pair of binding plates 126 to receive rotational force of the second drive motor (M2) and hinge rotation. Binding An angle conversion device 120 in which a sphere 127 is installed and a receiving groove 128 is provided on the top of the binding sphere 127 to form a bolt fastening with the lower end of the handrail frame 110 inserted; A second enclosure 132 having a guide groove 131 is installed on the other wall adjacent to the opening 10 so that the end of the handrail frame 110 hinged by the conversion device 120 can be seated, the A rotary gear 133 protruding toward the guide groove 131 is rotatably connected to one side adjacent to the guide groove 131, and the rotary gear 133 and the belt 134 are connected to the rear of the rotary gear 133. A third drive motor M3 is installed to provide rotational force by being connected through the guide groove 131, and a long groove 135 communicating with the guide groove 131 is formed on the other side wall of the guide groove 131, and the guide groove ( 131) is connected to a supporting plate 136 sliding along it, and a gear part 137 meshing with the rotating gear 133 is formed on one side of the supporting plate 136, and the supporting plate ( 136) on the other side of the anti-separation device 130 provided with a locking jaw 138 inserted into and connected to the long groove 135; An installation frame 143 having an accommodation space 141 is installed on both sides of the inner wall of the opening 10 to control the hinge rotation operation of the handrail frame 110, and an external power source is supplied to the accommodation space 141 When applied, a fourth drive motor (M4) that generates rotational force and a spiral shaft 145 that rotates by receiving the rotational force are installed, and the spiral shaft 145 has a lifting and lowering fixture 147 bound by a bolt-nut fastening method. ) is coupled, and a fall prevention device 140 provided with a clamp piece 149 that is engaged with the upper end of the handrail frame 110 at the end of the elevating fixture 147; A power supply unit 150 for supplying power to the first drive motor M1, the second drive motor M2, the third drive motor M3, and the fourth drive motor M4, and the first drive motor ( M1), the second driving motor (M2), the third driving motor (M3) and the fourth driving motor (M4) of the control unit 160 for controlling the operation, characterized in that the construction safety with an evacuation function Handrail." was disclosed as Patent Registration No. 10-1017133 (2022.02.25. Notice).

In the case of an emergency such as a fire in a building, the safety railing for construction having such a conventional evacuation function is operated by the angle conversion device 120, the departure prevention device 130, and the fall prevention device 140 to prevent the handrail frame 110 from falling. ) is automatically operated so that the residents can conveniently evacuate to the lower floor, while the angle conversion device 120, the departure prevention device 130, and the fall prevention device 140 are installed exposed to the outside, and the internal electronic Structural problems in which the product does not actually operate in an emergency due to malfunctions caused by moisture during the rainy season frequently occur, resulting in concerns about damage to people who could not evacuate in an emergency. There was a problem of high maintenance cost.
