Apparatus for fixing the bottom end of the CCTV post or street lamp post}

The present invention relates to a lower fixing device of CCTV props and street lamps, and in particular, it is possible to easily assemble and install the lower part of the prop pipe at the CCTV installation site so that the installation of the props can be easily and efficiently performed. The present invention relates to a lower fixing device for CCTV props and street lamps that can greatly reduce the overall costs and manpower required for transportation, thereby improving the economics of prop installation works.

Recently, in Korea, closed circuit TVs (closed circuits) on roads, entertainment districts, residential areas and children's sanctuaries in urban areas are used to help prevent crimes and detect criminals in various cities such as security, robbery, rape, and murder. The number of television (CCTV) installations is increasing rapidly. In particular, criminals that could have been neglected as permanent US cases without the CCTV were arrested and resolved by video footage recorded on CCTV, so CCTV is now essential to curb crimes in the city and promote citizen safety. Is in charge of.

In response to these times, CCTV has been actively used in almost all places such as roads, residential areas, nightlife, schools, apartments, parks and parking lots, not only by the government and local governments, but also by private companies such as corporations, residents' groups or individuals. The installation method of CCTV is slightly different depending on the place. In other words, when CCTV is installed inside the building, on the outside wall, or on the roof, you can fix the bracket at the proper location of the building and install CCTV. CCTV should be installed in the upper part of the landlord.

1 and 2 show the installation structure of a conventional CCTV prop 1. Referring to FIG. 1, existing CCTV props 1 embed concrete foundation structures 8 on the ground, as in the case of installing general facilities such as traffic lights, street lamps, road signs, or steel pipe poles. And the flange 6 of the support 1 is attached to the anchor bolt 8a protruding from the concrete foundation structure 8 to the ground.

In FIG. 1, a camera connection arm 3a extending in a horizontal direction is coupled to an upper portion of the CCTV support 1, and a CCTV camera 2 is installed at an end of the camera connection arm 3a. The camera connection arm 3a is connected to the support upper end 1a by a support wire 3a for structural stability thereof, and is supported by an upper reinforcing member 3b below. In most cases, a control box 4 is installed at the intermediate height of the CCTV post 1, and the control box 4 has a power device, an electronic device, and an earth leakage breaker for operation and signal transmission of the CCTV camera 2. Other necessary provisions such as surge protectors, speakers, etc. are built in.

On the other hand, in recent years, wooden or synthetic resin materials are used around the CCTV props (1) in order to supplement the shortcomings that the metallic props (1) appear too simple and cold and to enhance the aesthetic value and functionality of the CCTV props installed in the street. There is an increasing number of cases to attach the outer cover (5).

Figure 2 shows in more detail the manner in which the conventional CCTV prop 1 is combined with the concrete foundation structure 8 of the underground. The CCTV post 1 is usually made of a cylindrical or angular pipe. A flat flange 6 is joined to the lower end of the support pipe by welding, and a plurality of vertical lines are formed along the circumference of the post 1. The reinforcing plates 7 are welded to reinforce the connection structure between the support 1 and the flange 6. A plurality of anchor bolts 8a are embedded in the concrete foundation structure 8 embedded in the ground, and the upper ends of the anchor bolts 8a are exposed to the outside by a suitable length so that they are exposed to the anchor bolts 8a. The flange 6 of the support 1 can be fixed. Since the bolt through holes 6a are drilled in the flange 6 of the support 1 at positions corresponding to the anchor bolts 8a of the concrete foundation structure 8, the anchor bolts 8a Protruding upward through the flange 6 through the bolt through holes 6a, and tightening the anchor bolts 8a with the nuts 9 respectively, the support 1 becomes the concrete foundation structure 8 It is installed upright on the phase. In FIG. 2, reference numeral 9a denotes a washer fitted between the nut 9 and the anchor bolt 8a to prevent the nut 9 from loosening.

The installation structure of the conventional CCTV prop 1 as described above has no problem in terms of structural stability, but the installation process is required because the flange 6 and the vertical reinforcement plates 7 must be directly welded to the prop pipe every time. It was very complicated and cumbersome and had a disadvantage of poor workability. In addition, even when the holding pipe is taken to the installation site and coupled to the anchor bolt 8a of the concrete foundation structure 8, the position of the anchor bolt 8a is determined by the position of the bolt through hole 6a formed in the flange 6. If it does not fit, it was also very inconvenient to work because the holding pipe had to be fixed on the crane.

In addition, if the angle of the flange (6) and the support (1) is not exactly orthogonal, there is a problem that becomes hard when the CCTV support (1) is up, so the flange (6) to the lower end of the support (1) Work-related factors, such as the need to attach exactly orthogonal, also exist, the existing installation structure of CCTV props had a disadvantage in that the overall workability, such as labor costs, material costs, installation costs, etc. significantly increased.

The conventional prop pipe used as CCTV prop is welded to the installation site by the vehicle after welding the flange 6 and the vertical reinforcement plates 7 at the factory. Another problem was that it was difficult to load a large amount in the vehicle with the reinforcing plates 7 attached. Due to the protruding flange (6) and the vertical reinforcement plates (7), it is very unfortunate in these days of high oil prices that it is not possible to carry a large number of prop pipes at once and to transport them by several cars. The increase is also a big factor in raising CCTV installation costs.

Problems related to the installation structure of the conventional CCTV props as described above are equally applicable to other urban facilities installed using the props. That is, traffic lights, street lamps, road signs, and steel pipe poles are all installed by installing concrete foundation structures in the ground and fixing metal pillars on the ground, as in the case of CCTV shores.
