Description

Pier safety device {A safety device for pierces}

The present invention relates to a safety device for a pier, to consider the safety of workers working on the top of the pier, to ensure the safety of workers working on the bottom of the pier from falling objects falling from the top of the pier, Even if it is damaged, it is possible to function as a second safety facility, and to prevent access by the general public, and it is related to a pier safety device composed of a frame, a safety net support, and a safety net to prevent the safety accident of the general public.

Figure 1 is a perspective view showing a safety device for the beam is generally constructed in the lower part of the beam, the bridge is typically a number of piers (P) on the ground and after the beam (B) over the bridges (P) The slab is formed on the beam B.

A beam safety device 30 is installed below the beam B to prevent workers from falling and prevent falling of concrete blocks, wood and scaffolding pipes, various tools, and the like to prepare for safety accidents.

The beam safety device 30 secures a plurality of scaffolding pipes 31 to the lower portion of the beam B, and then fixes the safety net 32 to the scaffolding pipes 31 to be constructed.

In the construction of the bridge, while installing the beam safety device 30, the bridge (P) is not equipped with such a safety facility is a situation that many accidents.

Although the construction law requires the installation of safety devices when constructing more than 2m, the safety devices for piers are not installed even in bridges up to 100m high.

In the case of the pier (P), for the purpose of checking or repairing the pier (P), the workers hang on the rope or rely on the scaffolding structure installed on the upper part of the pier (P) to work on these, Even if it falls, there is no safety device, so there are many casualties or accidents.

In addition, even if the worker's tools or lumps of concrete separated from the upper part of the pier (P) or the scaffolding structure installed on the upper part of the pier (P) fall, there is no preparation for workers working under the pier (P), and the beam safety device ( 30 is damaged, the scaffolding pipe 31 falls, and even if the falling object falls through the perforated safety net 32, there is no second safety facility.

In addition, the public can not control the access of the general public is often killed or seriously injured by falling objects.

In this invention, in order to solve the above problems, construct a frame that is formed like a fence around the piers, and attach the safety net support that can fix the safety net on the piers to secure the safety net multiple up and down on the frame and the safety net support. As a result, it is possible to prevent falling of workers and falling objects at the upper part of the pier, and to function as a second safety facility that can prepare for damage to the beam safety device, and to prevent accidents in bridge construction by preventing public access. It is an object of the present invention to provide a safety device for pier to prevent in advance.

Hereinafter, with reference to the accompanying drawings will be described the configuration and effects of the present invention for achieving the above object.

Figure 2 is a perspective view showing an example of the construction of the bridge piers applied to the technology of the present invention was applied in parallel, Figure 3 shows a bridge safety device applied to the technology of the present invention as a single configuration Figure 4 is a perspective view showing an example constructed on the pier, Figure 4 is a perspective view showing only the lower safety net is installed as a safety device for the pier applied technology of the present invention, Figure 5 is a safety device for the pier to which the technology of the present invention is applied to the upper safety net and 6 is an exploded perspective view illustrating a state before the safety net support constituting the pier safety device constituting the pier safety device to which the technology of the present invention is applied, and FIG. 7 is a technology of the present invention. It demonstrates together with the perspective view which shows that the safety net support which comprises this applied pier safety device was attached to the pier.

In general, the bridge is composed of a bridge (P), which is constructed on the ground, a beam that extends over the bridge (P) and a slab that is constructed on the beam.

Pier safety device 100 according to the present invention is a frame 110 installed in the shape of a fence around the pier (P) and the safety net support 120 and the frame 110 attached to the pier (P) 110 And it is composed of a plurality of safety nets 130 fixed to the safety net support 120 is characterized in that to prevent the accident in the bridge construction in advance.

The frame 110 has a plurality of vertical bars 111 are vertically erected around the pi (P), a plurality of horizontal bars 113 and X ( It consists of a support bar 115 is fixed by the connecting means to the vertical bar 111 and the horizontal bar 113 in the X) shape.

As an example of the frame 110, the vertical bar 111, the horizontal bar 113 and the support bar 115 may be configured as a scaffold pipe, and the connecting means for connecting the scaffold pipes may be a clamp for the scaffold pipe. However, in the present invention, the structure of the frame is not limited to the clamp for the scaffolding pipe and the scaffolding pipe, and the vertical bar 111, the horizontal bar 113, and the support bar 115 may be any bar shape. Any means for connecting bars such as wire to bolts and welding is possible.

The safety net support 120 is between the ring 121 and the pi (P) phase interposed between the removable ring 121 and the ring 121 and the pi (P) phase attached to the outer periphery of the pi (P) It is composed of a plurality of separation blocks 127 to form a gap, the separation block 127 is configured to be attached to the inner side (part in contact with the bridge (P)) of the ring 121.

The ring 121 is bisected and configured, flanges 123 are formed at both ends of the bisected rings 121, and bolt holes 124 through which the bolts 125 pass are formed at the flange 123. A bolt 125 and a nut 126 are formed to couple the ring 121 bisected through the bolt hole 124.

The spaced block 127 is made of a material having a high coefficient of friction to prevent the ring 121 from slipping down and high elasticity, elasticity is provided to prevent the ring 121 from loosening after being clamped, Examples include wood, rubber and synthetic resins with high coefficients of friction.

After allowing the ring 121 to which the separation block 127 is attached is combined around the pier P, the ring 121 presses the separation block 127 by the bolt 125 and the nut 126. To be attached to (P), the separation block 127 is provided with elasticity can be strongly tightened ring 121 to press the piers (P) to be firmly attached to the ring 121, the ring By forming a gap between the upper portion of the 121 and the pier P, the safety net 130 may be tied to the ring 121 with a string or the like.

After attaching a plurality of the ring 121 to the pi (P) up and down, the safety net 130 can be multiplexed between each of the ring 121 and the frame 110, so that the more robust safety net 130 of It is possible to install, and the fixing of the safety net 130 can be carried out in a variety of configurations, such as hanging on the ring 121 and the frame 110 by tying with a string or by connecting a ring to the safety net 130.

According to the present invention by the above configuration, by installing a plurality of solid safety nets 130 around the pier P, it is possible to prevent the falling of workers and falling objects on the pier (P) upper, damage to the beam safety device Even if the scaffolding pipes and various falling objects fall, it is possible to function as a second safety facility, and is configured around the bridge P to have an effect of preventing the access of the public, thus preventing the safety accidents of the public in advance.

According to the present invention by the above configuration, the construction of the frame around the piers, and by attaching a safety net support for fixing the safety net to the piers by fixing the safety net multiple up and down in the frame and the safety net support, at the top of the piers It is possible to prevent falling of workers and falling objects, and to function as a second safety facility that can prepare for damage to the beam safety device, and to prevent public accidents from preventing accidents in bridge construction. There is.
