Description

Earth quake-proof reinforcement structure installed for operating electric panel anticipating high earthquake response without moving and interruption of power supply}

The present invention relates to an earthquake-proof reinforcement structure that is mounted to reinforce seismic performance in a distribution panel or relay panel that is a power supply. More specifically, the present invention provides a seismic reinforcing member in an existing distribution panel or relay panel. The present invention relates to an earthquake-resistant reinforcement structure that is installed in an uninterrupted and non-removable manner by installing seismic reinforcing members in a non-seated and uninterrupted state and having a high earthquake response relay panel having seismic performance due to an earthquake or vibration.

Currently, power supply facilities such as relay panels, or monitoring panels, distribution panels, communication panels, protection panels, control rooms, communication control lines, computer equipment, control rooms, etc., are installed in the double floor system by installing another floor plate on the building floor. If you look at the seismic reinforcement structure presented in the Republic of Korea Patent Registration No. 850,228 patented by the applicant here, first, by applying epoxy adhesive to the vertical support rods at a predetermined interval on the concrete slab floor, On this floor slab, a mounting base plate is provided in double through vertical support rods.

Then, the relay panel or switchboard and the above-mentioned equipments are installed on the installation base plate. When the relay panel is heavy, it is fixed by anchor nails to two of four holes in the installation base plate. Place a shock pad on the top of the head and connect the upper position fixing supports to the vertical holding rods in all directions to fix them with bolts. On top of that, the top plate is assembled in all directions to match the cushion pad groove. Here, the top plate is made of iron plate (610mm × 610mm, thickness 32mm), which is the old system. However, recently, polyurethane and particle board integrated type (600mm × 600mm, thickness 36mm) that solved the shortcomings of iron plate were used. Mainly used.

The height of the vertical holding rod of the conventional double-bottom system is about 20 ~ 40 ㎝, the existing supporting force of the top plate is 1.5 ton / ㎡, and the reinforcement of the vertical support rod is 3.5 ton / ㎡.

Therefore, the weight of the relay panel is about 100㎏ ~ 800㎏, so it has sufficient bearing capacity.

However, in the event of an earthquake, the existing floor type of the double-floor system is a ramen structure that excludes bracing and not a completely fixed end.

On the other hand, when installing various equipment or devices inside a building or structure to which earthquake-resistant design is applied, before installing the double floor system, make a frame from the section steel according to the size of the supporting plate of the equipment or equipment such as the relay panel and place the slab on the floor. After installation, assembling the double-floor system that anchors the installation bottom plate over the remaining space, and laying the control cable and finally assembling the top plate after the connection work, the conventional double-floor system installation Not only was the construction procedure cumbersome, but it also cost a lot of money to manufacture the steel frame.

In addition, the seismic reinforcement structure of the double-floor system for installing a conventional switchboard or relay panel as described above was applicable to new buildings and new equipment or facilities, but seismic reinforcement in existing equipment such as switchboards or relay panels. There is a problem that can not be applied in the operation of the equipment because the power outage or relocation to install the structure.

Accordingly, the present invention has been invented in view of the above-described conventional problems, and the seismic performance is reinforced so that the equipment installed on the double-floor system does not fall or damage the earthquake movement when an earthquake or impact occurs, and in particular, installs a seismic reinforcing structure in the equipment in operation. Its purpose is to provide a seismic reinforcement structure that is installed in an uninterruptible and non-separable manner in relay panels that receive high earthquake response that can be installed without relocation and without seizure of this equipment to ensure seismic safety. have.

The present invention for achieving the above object is spaced apart from the bottom slab, the support top plate is installed via the fitting member of the vertical support rods, the switchboard equipment is seated on the mounting bracket fixed to the support top plate to ensure the seismic safety from earthquake movement In the seismic reinforcing structure which is installed in the relay panel for uninterrupted and no-separation, the support top plate and the mounting bracket is fixed to the L-shaped bracket and horizontal and vertical bolts, and penetrates the L-shaped bracket and the support top plate. The vertical bolts are fastened tightly to each other by the angle tube, and the angle connecting bracket and the fixing bolt are connected to each other through the vertical support rod and the L-shaped steel, and are connected by turnbuckles to the end brackets of the vertical axis and the anchor bracket of the bottom slab. It is a rigid structure in which rod fixing bracket is connected with turnbuckle or fret bar.

The seismic reinforcement structure installed in the relay panel according to the present invention as described above in an uninterruptible and non-separable manner can be installed by adjusting the distance using a turnbuckle when the relay panel is installed in the existing operation panel, and the operation of the relay panel is not stopped. Therefore, it is possible to install a seismic reinforcing structure with reinforcement in seismic performance while maintaining uninterrupted and no relocation.
