Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reinforcement device for a communication device that enhances the earthquake resistance of the communication device and prevents damage to the communication device due to a fall during an earthquake.

[0002]

[Prior art]

 In general, communication equipment has a rectangular box that is long in the height direction and extremely short in the front-back direction compared to the height direction, and this box is fixed to the floor, ceiling, and walls of the building with bolts, etc. is doing. However, in the event of an earthquake, the walls, ceiling, etc. do not have the same amplitude, cycle, etc. with the floor, so even if the box is fixed to each part of the building, the fixtures such as bolts are destroyed and the communication equipment falls over. And damage.

Therefore, a reinforcing device for preventing the communication device from falling over during an earthquake is known. This stiffening device consists of four pillars arranged at each corner of a rectangular plane, with the arms protruding at right angles to each other in the left-right and front-rear directions at right angles to each other, and two arms facing each other in the front-rear direction. The arms of the pillars are butted and fixed, and the arms of the two pillars facing each other in the left-right direction are butted and connected to each other via the side connecting members arranged between them. Then, the lower ends of the columns are connected to the floor, and the boxes of the communication device are inserted and held in a row between the side connecting members and the left and right columns in a row.

[0004]

[Problems to be solved by the device]

 However, in the above-described conventional reinforcement device for communication equipment, since the arms provided at the upper ends of the columns are abutted and fixed directly or through the side connecting members, the abutting surface is displaced and the fixing work is not performed. Since it is troublesome and fixed by abutting, and the lower ends of the columns are not connected, there is a problem that the communication device cannot be sufficiently reinforced and held. In addition, if it is necessary to attach a component or accessory to a support after or after assembling the reinforcement device for communication equipment, such an outlet or accessory should be installed in a good-looking manner. There was a problem that I could not do it.

An object of the present invention is to solve the problems of the above-described conventional reinforcement device for a communication device, and to easily fix each member to the upper end portion of the column, which can be assembled with good workability. Another object of the present invention is to provide a reinforcing device for a communication equipment device, which is not easily deformed in the event of an earthquake, can firmly hold the box of the communication equipment device, and can reliably prevent the communication equipment device from falling.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a reinforcing device for a communication device to an upper end portion of four columns having longitudinal gaps arranged at respective corners of a rectangular plane and another column. To form notches on the opposing portions of the front and rear side connecting bodies and the corners of the central connecting body disposed between the side connecting bodies on the notches of the columns. The projection pieces, which are respectively placed and project below both ends of the side connecting body and the corners of the central connecting body, are inserted and fixed in the respective columns, and front and rear sets are also provided. The lower ends of the left and right columns are connected and fixed by the front and rear mounts placed between them, respectively, and the box of the communication device is placed inside the left and right columns, the side connection body and the base. It is made up of front and rear frames, and the side connecting body flange and the center connecting body flange are , The side connecting body and the central connecting body are connected by sandwiching between the holding metal fittings and the screw back plate, and further, the blind plate is attached to the space between the columns. Furthermore, reinforcement members are attached to the inside of the support columns at predetermined intervals.

[0007]

[Action]

 The reinforcing device of the communication device according to the present invention inserts the projecting pieces provided on the side connecting member and the central connecting member into the notches formed at the upper end of each strut, and inserts them into the strut. Since it is fixed with bolts, etc., the side connecting body and the central connecting body can be easily fixed to the upper end of the column, and the lower end of the column can be easily connected to the pedestal, so that it can be assembled with good workability. it can.

[0008] Furthermore, since the lower ends of the left and right columns of the front and rear frames are connected to each other by the frame-shaped frame, the portion to be supported on the floor of the building becomes large and can be securely fixed to the floor. Since the upper end portions are connected to the side connection body and the frame-shaped central connection body by the projecting pieces provided on these connection bodies, the upper and lower corner portions of the front and rear frame bodies are strongly connected. Therefore, even in the event of an earthquake, the front and rear frames are unlikely to be distorted in shape, and the boxes of a plurality of communication device devices can be firmly held without fear of falling.

Further, since the support is provided with a gap, it is possible to mount an outlet or an accessory device inside the support.
