Description

Rigidity reinforcement street light manufacturing method}

The present invention relates to rigidly reinforced streetlights.

In general, street lights are installed along roadsides, residential areas, or parks, and have the function of illuminating a specific location at a certain level of illumination or higher.

To describe the conventional streetlight in more detail, a streetlight consists of a vertical light pole fixed vertically on the ground, a horizontal support pole fixed to the top of the vertical light pole and having a parallel length, and a lighting fixture provided at the end of the horizontal light pole to emit light. Includes.

Such street lights radiate light from fixed lighting fixtures to maintain a constant level of illumination in the surrounding area.

As disclosed in Patent Registration No. 10-1125424 (2012.03.02.), the conventional streetlight is a streetlight in which a luminaire including an arm is installed on the upper part of a support, and the insertion member in which the ribs are integrally formed and the base plate are integrally formed. It is composed of a reinforcing member formed of. As such, the conventional street light is provided with an insertion member in which a bolt insertion hole for fixing the reinforcing member and the strut is formed in a cylindrical insertion member into which the reinforcing member and the strut are inserted, and a rib is welded to the outer periphery. It has the characteristic of being fixed by inserting a support into the space between it.

However, since conventional streetlights do not have a means to suppress bending and deformation caused by external forces or stresses generated in the streetlight itself, the lifespan of the streetlight itself is short, and the base and support can be separated or damaged, and can easily be damaged by shocks from external forces. There was a serious problem of bending and deformation.

In particular, when streetlights are installed on bridges, the vibrations of vehicles passing through the bridge are directly transmitted, causing an increase in stress due to vibration compared to streetlights installed outside of the bridge, resulting in a shorter lifespan.

In addition, since the wind blows strongly on bridges in addition to vehicles, the vibration stress caused by the wind is added to streetlights installed on bridges, which not only shortens their lifespan but also increases maintenance costs.

In addition, to reinforce the rigidity of streetlights, reinforcing bars are commonly installed by welding, and welding is used to connect and fix each pole. However, as described above, the rigidity of the welded area decreases due to vibration stress, so the poles of the streetlight are connected. There was a serious problem of bending deformation or falling of the streetlight based on the area and reinforcement area.

In addition, conventional street lights are not easy to manufacture because they have an insertion member in which the base and ribs are formed integrally, and they cannot be installed on existing street lights, so there is a problem of zero efficiency.

In addition, since the insertion member does not have a separate structure to support the ribs, it has a low bearing capacity and is easily damaged by external force or stress generated in the streetlight, which poses a serious problem of bending or deforming the streetlight or collapsing the streetlight.

In addition, conventional streetlights are difficult to manufacture like the aforementioned insertion members because separate reinforcing members are inserted into the struts, and they cannot be installed on existing streetlights, so there is a problem of zero efficiency.

Additionally, the base of a conventional street light can be provided with an elastic body capable of absorbing vibration. However, since streetlights are made of steel, a plating process is required, so a problem may occur in which the elastic material melts during the plating process. In other words, after the production of the base of the streetlight was completed, a means was needed to secure the elastic body to the base as a whole.

Hereinafter, a rigidly reinforced streetlight manufactured by the rigidly reinforced streetlight manufacturing method according to the present invention will be described in detail.

2 to 9, the rigidity-reinforced streetlight according to the present invention includes a lower support 100, a main support 200, and a back support 300.

The lower support 100 is installed on the ground.

At this time, concrete is poured on the ground and installed on the concrete using anchor bolts. The ground described in the present invention may be concrete, but is not limited thereto.

Here, the lower support 100 may be fixed with nuts or the like after passing an anchor bolt provided in concrete (foundation) formed on the depressed ground through the coupling hole of the lower support 100. This installation process of the lower support 100 is a typical streetlight installation process, and detailed description will be omitted.

The main support 200 is coupled to the lower support 100.

The back support 300 is laterally coupled to the upper part of the main support 200.

At this time, the light pole 300 may be provided with a lighting fixture at its end.

In addition, the main pole 200 and the back pole 300 are formed in an annular shape, so that a lighting fixture and a wire that transmits power can be provided therein.

Hereinafter, each component and the connection relationship between components will be described in detail.

First, the lower support 100 is comprised of a plurality of plates and is coupled to each other to absorb vibration transmitted from the ground.

In particular, vibrations continuously occur in bridges due to vehicles and wind, and this vibration exerts vibration stress on streetlights.

By minimizing this vibration stress, the lifespan and maintenance of the rigidity-reinforced streetlight of the present invention can be improved.

In order to minimize vibration stress, it is desirable for the lower support 100 to be able to absorb vibration, but the present invention is not limited to this.

The lower support 100 may include a plate portion including a first plate 110, a second plate 120, and a third plate 130, and a vibration absorbing elastic body 140.

The first plate 110 is provided on the ground, and a first fastening hole 111, a first coupling hole 112, and a first fixing hole 113 are formed.

The second plate 120 is provided on the first plate 110, and a second fastening hole 121, a second coupling hole 122, and a second fixing hole are formed.

The third plate 130 is provided on the second plate 120, and a third fastening hole 131 and a third coupling hole are formed.

That is, the first plate 110, the second plate 120, and the third plate 130 are stacked from the bottom to the top.

At this time, the fastening hole, coupling hole, and fixing hole formed in each plate may be formed identically to each other, and are provided to communicate vertically. That is, the first plate 110 to the third plate 130 may be integrated by welding or the like to form a plate portion in a state in which the respective fastening holes, coupling holes, and fixing holes are stacked in communication with each other, and a description of this will be provided later. do.

The vibration-absorbing elastic body 140 is provided in the first fixing hole 113 and the second fixing hole and is capable of absorbing vibration.

That is, the vibration-absorbing elastic body 140 is made of a urethane material capable of absorbing vibration, and can receive and absorb vibration transmitted to the lower support 100. Such vibration absorption can minimize vibration transmitted to the main support 200.

Meanwhile, the first plate 110 and the second plate 120 are coupled so that the first fixing hole 113 and the second fixing hole communicate.

At this time, the vibration absorbing elastic body 140 has an outer peripheral surface formed with a diameter that does not come into close contact with the inner peripheral surface of the first fixing hole 113 and the second fixing hole, and the thickness of the first plate 110 and the second plate 120. It may be formed to have a longer length and be provided to protrude below the first plate 110.

For example, the first fixing hole 113 and the second fixing hole may be formed to have the same first diameter. At this time, the vibration-absorbing elastic body 140 may be formed to have a second diameter smaller than the first diameter, and may be formed to have a second thickness that is longer than the first thickness of the first plate 110 and the second plate 120. It can be.

Accordingly, in a state where the first plate 110 to the third plate 130 are integrated, when the bottom of the first plate 110 is in close contact with the ground, the lower end of the protruding vibration-absorbing elastic body 140 is compressed against the ground. It can be fixed at the same time as being in close contact with the inner peripheral surfaces of the first fixing hole 113 and the second fixing hole. And, by absorbing vibration transmitted from the ground, vibration transmitted to the main support 200 can be minimized.

Meanwhile, the first fixing hole 113 may be formed with a first diameter, and the second fixing hole may be formed with a second diameter. At this time, when the vibration-absorbing elastic body 140 is inserted into the second fixing hole through the first fixing hole 113, it can be fixed by being pressed into the second fixing hole having the same diameter as the vibration-absorbing elastic body 140.

Here, the air that is press-fitted and compressed inside the second fixing hole can be discharged through a fine gap formed when the second plate 120 and the third plate 130 are stacked.

With the vibration-absorbing elastic body 140 being press-fitted in this way and fixed to the second fixing hole, the plate portion is positioned so that the bottom of the first plate 110 faces the ground, and then the anchor bolt and nut described above are fixed to form the vibration-absorbing elastic body. (140) is compressed on the ground and expands while being completely inserted into the second fixing hole, so that it can be closely fixed to the inner peripheral surface of the first fixing hole 113 and the second fixing hole.

Meanwhile, the vibration absorbing elastic body 140 can be coupled to the plate portion when installing a street light after completing plating and painting the plate portion.

Meanwhile, the lower support 100 may further include a coupling member 150 coupled to the first coupling hole 112 to the third coupling hole.

And, the plate portion including the first plate 110, the second plate 120, and the third plate 130 has a first fastening hole 111, a second fastening hole 121, and a third fastening hole 131. ) can be stacked in communication with each other.

The coupling member 150 has a locking protrusion 151 that hangs on the upper part of the third plate 130 at the top, and protrudes from the lower part of the locking protrusion 151 and is provided inside the first coupling hole 112 to the third coupling hole. It may include a coupling bar 152.

The coupling bar 152 may be formed with a length that does not protrude to the lower part of the first plate 110 and a diameter that does not allow the outer peripheral surface to come into close contact with the inner peripheral surface of the first coupling hole 112 to the third coupling hole.

For example, the first fastening hole 111 to the third fastening hole 131 may have the same third diameter, the coupling bar 152 may be formed with a fourth diagonal smaller than the third diameter, and the thickness of the plate portion may be It can be formed to have a smaller length.

Due to this, the locking protrusion 151 is caught on the upper part of the third plate 130, and the coupling bar 152 is sequentially connected to the third fastening hole 131, the second fastening hole 121, and the first fastening hole 111. It is inserted without protruding into the lower part of the first fastening hole 111, that is, the lower part of the first plate 110.

Here, the coupling member 150 can introduce molten material between the first coupling holes 112 to third coupling holes and the coupling bar 152 by welding the opened first coupling hole 112. At this time, as the melt solidifies, the first plate 110 to the third plate 130 can be integrated.

At this time, the coupling bar 152 may be formed with a plurality of irregularities on the outer circumferential surface to increase the fixing force by increasing the contact area with the melt.

In addition, the solidified material that protrudes into the first coupling hole 112 during welding can be post-processed to flatten the bottom surface of the first plate 110 by working with a grinder or the like.

Meanwhile, referring to FIG. 3, in a stacked state, the first plate 110 to the third plate 130 can be manufactured into an integrated plate portion by connecting the outer peripheral surfaces to each other by welding. At this time, it is preferable that the welded parts are welded at regular intervals, but it is not limited to this.

That is, as the first plate 110 to the third plate 130 are stacked, a fine gap may occur between them. Here, all fine gaps can be closed by welding the entire plate along the outer peripheral surface, but only a portion of the plate is welded so that vibration, rainwater, etc. can be easily discharged to the outside.

In other words, vibration and foreign matter transmitted from the ground may be discharged to the outside to the non-welded area.

As shown in Figure 2, the welded area is shown as a thick line on the plate part.

Meanwhile, the rigidly reinforced streetlight according to the present invention may further include a triangular reinforcement bar 160 and a gusset 170.

The triangular reinforcement 160 is fixed to the upper side of the lower support 100 and the lower outer peripheral surface of the main support 200 by welding. At this time, the triangular reinforcement bar 160 is commonly installed in streetlights and may be formed as a right triangle, with a vertical side of a right angle, a horizontal side at the bottom, and an inclined plane connecting the side and the bottom.

The gusset 170 can be provided at the welded portion of the triangular reinforcement bar 160 to reinforce rigidity.

Here, the triangular reinforcing bar 160 is fixed by welding, but damage may occur at the welded area due to vibration stress, and as external shock is concentrated on the upper edge of the triangular reinforcing bar 160, bending may occur. A gusset 170 that can additionally reinforce the reinforcement bar 160 is required.

For example, when an external impact is applied to the main support 200, the gusset 170 can be additionally reinforced to disperse the external force and at the same time reinforce the rigidity of the streetlight.

The gusset 170 may include a side reinforcement bar 171 and a lower reinforcement bar 173.

The side reinforcement bar 171 has a first fitting groove 172 formed at the bottom so as to be inserted into the side of the triangular reinforcement bar 160, is inserted into the triangular reinforcement bar 160 through the first fitting groove 172, and has a rear side. It can be fixed by welding while being provided to surround the outer peripheral surface of the main support 200.

That is, the outer edge of the side reinforcement bar 171 is fixed by welding to the outer peripheral surface of the main support 200, and the first fitting groove 172 is fixed to the side of the triangular reinforcement bar 160 by welding, thereby preventing vibration transmitted from the ground. It is possible to increase the rigidity of the triangular reinforcement bar 160 to withstand the stress caused by and to disperse external forces.

The lower reinforcing bar 173 has a second fitting groove 174 formed on the side to be inserted into the lower part of the triangular reinforcing bar 160, and is fitted into the triangular reinforcing bar 160 through the second fitting groove 174, and the lower side is It is fixed by welding while being provided on the upper side of the lower support 100.

That is, the outer edge of the lower reinforcement 173 is fixed to the upper side of the lower support 100 by welding, and the second fitting groove 174 is fixed to the lower part of the triangular reinforcement 160 by welding, The rigidity of the triangular reinforcement 160, which withstands stress due to vibration, can be increased and external forces can be distributed.

In particular, when installing a street light, the side reinforcement bar 171 and the lower reinforcement bar 173 are fixed to the triangular reinforcement bar 160 and then connected to the surrounding area by welding, thereby enabling easier fixation of the gusset 170. Rather, work efficiency can be improved as work time is shortened.

Meanwhile, the first fitting groove 172 and the second fitting groove 174 may be formed to have a width wider than the thickness of the triangular reinforcement bar 160. Accordingly, after installing the triangular reinforcing bar 160 by welding, the side reinforcing bar 171 and the lower reinforcing bar 173 are respectively fixed and additionally welded, so that the main support 200, the side reinforcing bar 171, and the triangular reinforcing bar ( 160) can be fixed integrally. In addition, the lower support 100, the lower reinforcement 173, and the triangular reinforcement 160 can also be fixed integrally.

In this way, the main support 200, the lower support 100, the triangular reinforcement 160, and the gusset 170 are all integrally connected and fixed through fixation through welding, so that not only can they withstand external shocks, but also vibration. It can withstand stress and maintain the expected lifespan of streetlights, making maintenance easier.

Meanwhile, the rigidly reinforced streetlight according to the present invention may further include an extension support 210.

The extension pole 210 extends the vertical length of the main pole 200 between the main pole 200 and the back pole 300.

At this time, the lower part of the extension strut 210 having a certain length is fitted into the upper part of the main strut 200, and the upper end of the main strut 200 is welded and fixed.

At this time, if only the upper end of the main strut 200 and the outer peripheral surface of the extension strut 210 are fixed through welding, external force due to wind, etc. is concentrated on the fixed portion, thereby causing bending (a phenomenon in which the extension strut 210 is bent). You can. In order to prevent this, it is necessary to improve the fixing force between the main support 200 and the extension support 210.

Accordingly, the main pillar 200 may be formed with an exposed hole 201 penetrating the upper outer circumferential surface so that the lower outer circumferential surface where the extension pillar 210 is inserted is exposed. At this time, a plurality of exposed holes 201 may be formed, but since external force may be concentrated on the exposed holes 201, it is preferable that they are not formed on the same horizontal plane but at different positions, but the present invention is not limited to this.

That is, the main strut 200 and the extension strut 210 are fixed to each other as the molten material is filled and solidified by welding in the exposed hole 201, and at the same time, the molten material is in contact with the inner peripheral surface of the main strut 200. They can flow in between the outer circumferential surfaces and be fixed to each other.

In addition, the extension strut 210 may be indented along the width direction of the lower outer circumferential surface, forming a flow path through which melted material flows between the outer circumferential surface of the extension strut 210 in contact with the inner circumferential surface of the main strut 200. By forming the flow path, the extension support 210 may have a plurality of uneven lines formed at the bottom.

In addition, the main support 200 and the extension support 210 can be fixed more strongly by solidification of the melt flowing into the flow path, and the occurrence of bending can be prevented as the lower part of the extension support 210 is fixed as a whole.

Meanwhile, the rigidity-reinforced streetlight according to the present invention may further include a supporter 180.

The supporter 180 can suppress bending deformation of the main strut 200 by reinforcing the rigidity of the main strut 200.

The supporter 180 includes a first fixing protrusion 181 that is welded and fixed to the inner lower part of the main post 200, and a second fixing protrusion 182 that is welded and fixed to the inner upper part of the main post 200. , a first turnbuckle (183) whose lower end is coupled to the first fixing protrusion (181), a second turnbuckle (184) whose upper end is coupled to the second fixing protrusion (182), and an upper end of the first turnbuckle (183). It may include a wire 185 connected to the bottom of the second turnbuckle 184.

At this time, the first fixing protrusion 181 and the second fixing protrusion 182 may be provided on the inside of the upper and lower ends of the main support 200 by welding.

Also, the first turnbuckle 183 and the second turnbuckle 184 can be connected with a wire 185 to adjust the tension of the wire 185.

At this time, the supporter 180 may be provided on the other side opposite to one side of the main support 200 on which the back support 300 is provided. Accordingly, it is possible to prevent the main pillar 200 from bending due to the weight of the back pillar 300, but the present invention is not limited to this.

For example, the supporter 180 may be installed to be biased from the central axis of the main support 200.

Meanwhile, the supporter 180 may further include an elastic portion 186.

A plurality of elastic parts 186 may be provided on the wire 185 at regular intervals.

At this time, the elastic portion 186 may absorb the vibration transmitted to the wire 185 and radiate it to the inside of the main support 200. Accordingly, the elastic portion 186 may be made of an elastic material that can be shaken by vibration, but is not limited to this.

This elastic portion 186 may include a fitting ring 187 and a vibration reduction protrusion 189.

The fitting ring 187 is formed with a fitting groove 188 that is fitted into the wire 185. At this time, the fitting ring 187 can be firmly fitted to the wire 185.

In addition, a clamp located below the fitting protrusion to prevent the elastic part 186 from moving downward and may further include a clamp that supports the fitting ring 187 by being fixed to the wire 185.

A plurality of vibration reduction protrusions 189 are radially arranged and fixed at one end to the outer peripheral surface of the fitting ring 187, and have an elastic force capable of causing shaking due to external force.

At this time, when the vibration transmitted from the ground and external wind is transmitted to the wire 185, the vibration reduction protrusion 189 absorbs the vibration as it is shaken by the vibration transmitted to the wire 185, and at the same time, the vibration reduction protrusion 189 Vibration transmitted to the back support 300 can be reduced by concentrating it at (189).

Additionally, the vibration reduction protrusions 189 may be formed in a fan-shaped arrangement along the biased wire 185.
