Description

Concrete smart land lighthouse with PC modularity and its construction method {Concrete smart land lighthouse with PC modularity and its construction method}

The present invention relates to a land lighthouse and its construction method. In particular, the lighthouse is installed to be firmly supported on a monopile built into the land, so that it is stable against seismic loads, and is installed as a unit module, making construction of the lighthouse easy. This is about a concrete smart land lighthouse and its construction method using PC modularization that prevents theft of various facilities and allows inspectors to easily enter and exit the lighthouse.

In general, a lighthouse is a structure built on land to project light far into the surrounding area and is a type of navigation indicator. Lighthouses are divided into manned lighthouses and unmanned lighthouses. Lighthouses are used to mark dangerous coastlines, rough shoals or reefs, safe entrances to ports, etc., and also help with the navigation of aircraft.

There are problems with constructing a lighthouse on site, such as difficulty in pouring concrete due to moisture in the surrounding sea. Therefore, a technology for assembling a lighthouse with a modular structure has been proposed. However, this technology has the disadvantage that the light pole becomes unstable due to the seismic load when an earthquake occurs because the basic concrete on which the light pole will be installed is structured in the ground under its own weight. Therefore, the development of a lighthouse that excludes on-site concrete pouring and is stable against seismic loads is required.

The technology behind the present invention is Korean Patent Registration No. 10-2108265 (Patent Document 1), which proposes a 'lighthouse that can be assembled separately'. This classifies the components that make up the lighthouse into the top, middle, and bottom, and allows each component to be installed in a prefabricated manner at the installation site, so that a lighthouse can be constructed at a height that suits the site conditions, and partial damage to the lighthouse can occur. Even if it does, it has the advantage of being easy to maintain because only the relevant area needs to be replaced. However, the above background technology has the disadvantage that the lighthouse becomes unstable due to seismic load when an earthquake occurs because the foundation concrete supporting the bottom is not fixed to the ground.

Below, the present invention will be described in detail with reference to embodiments shown in the attached drawings, but the presented embodiments are illustrative for a clear understanding of the present invention, and the present invention is not limited thereto.

The concrete smart land lighthouse according to an embodiment of the present invention is constructed by penetrating into the installation area of the ground 5, as shown in Figures 1 to 3, and includes a plurality of monopiles 12 arranged in a grid, and the upper end of the monopiles 12. To protect the light pole (30) and the light pole (30) at the top of the light pole (30), which is mounted on and fixed to the base concrete (20) and which is installed on the base concrete (20) and has a vertical ladder (34) installed in the height direction inside. It includes a lantern (40) installed for the purpose.

As shown in FIGS. 3A and 3B, the monopile 12 is made of a circular steel pipe, and a saw blade 121 for cutting the rock layer 7 is formed at the bottom, and a base support plate for supporting the base concrete 20 at the top. (122) is provided. Therefore, the monopile 12 is stably supported and installed in the vertical direction by cutting a part of the rock layer 7 during rotational penetration. The monopiles (12) are arranged in a grid in two rows and two columns, but additionally may be installed depending on the size or load of the light pole (30).

In this way, the monopile 12 exhibits excellent bearing capacity because the saw blade portion 121 crushes the sandstone, gravel, etc. of the soft ground and penetrates into the bedrock layer 7 during construction. Therefore, the light pole 30 can effectively resist the horizontal force generated when an earthquake occurs by being firmly installed on the foundation concrete 20 connected and supported by the monopile 12 stably penetrated deep into the ground.

As shown in Figures 5a and 5b, the base concrete 20 is made up of base module blocks 22 that are fitted and mounted on the top of each monopile 12 and joined together. As shown in FIG. 4, the base module block 22 has a block coupling groove 221 formed to a certain depth on the lower surface to be inserted into the top of the monopile 12, and connecting bar links 223 and 223 that protrude from the side cross section and are arranged in a lattice. , It has an L-shaped vertical passage 225 formed in the center of the base concrete 20 to form a square hole 20a for connecting the light column. A method of constructing the base concrete 20 by applying the base module block 22 will be described later.

The light column 30 is made of precast concrete modules or glass fiber reinforced plastic (GFRP), and has a circular or polygonal cross-section by horizontally joining the light column unit modules 32 of FIG. 7. As shown in Figure 8a, the light pole 30 can be connected to the base concrete 20 through anchor bolts 37 installed in a circular arrangement. This can be achieved by injecting a binder into the binder injection port 30a on the lower side of the light pole 30 to join the anchor bolt 37 and the light pole unit module 32. Filling is completed by moving the injected binder to the binder discharge port (30a). The binder may be non-shrink mortar or adhesive depending on the material of the light column 30.

Here, the light column unit module 32 is manufactured by dividing it into a plurality of pieces in the circumferential direction and then vertically joined, and the vertical joints between the light column unit modules 32 and 32 adjacent above and below are preferably formed at positions offset from each other. At this time, as shown in FIG. 8B, for example, the upper and lower light column unit modules 32 made of precast concrete can be coupled through the connecting bars 39 arranged in a circle. This forcibly injects the binder into the binder injection port 32a on the light column unit module 32 side, thereby coupling the connecting bar 39 and the light column unit module 32. Filling is completed by moving the injected binder to the binder discharge port (32b). Of course, when the light pole unit module 32 is made of glass fiber reinforced plastic (GFRP), a flange can be formed on the inside and connected to each other by screwing bolts and nuts.

Meanwhile, an anti-theft door 50 is installed at the lighthouse entrance 302 formed at the lower part of the light pole 30. The anti-theft door 50 is operated by a drive motor (not shown) controlled by a remote control in a manner that opens and closes by rotating with a hinge at the bottom. In addition, on the side of the lighthouse entrance 302, an automatic folding electric staircase 60 is further installed to perform an unfolding operation and a folding return operation by operating a remote control while the anti-theft door 50 is open. It can be. The automatic folding electric staircase 60 is a known technology in which stairs connected to a link are folded and unfolded in conjunction with a drive motor, and detailed description will be omitted.

Next, base concrete 20 is installed on the top of the monopile 12 as shown in FIGS. 3b and 5.

The base concrete 20 supports the base module blocks 22 inserted through the block coupling grooves 221 at the top of each monopile 12, and is exposed at the cross section facing the base module blocks 22. A connecting bar (24) is inserted into the overlapping area between the block connecting bar connecting rings (223 and 223) arranged in a grid, and a block connecting bar connecting ring (223) is placed between the neighboring base module blocks (22 and 22). It is installed by filling and bonding concrete so that the connecting bar 24 is buried.

Next, after installing the light pole 30 with the vertical ladder 34 inside the concrete base 20 as shown in FIGS. 1 and 6, protect the light pole (not shown) at the top of the light pole 30. Install a lantern (40) for this purpose.

Here, an anti-theft door 50 is installed at the lighthouse entrance 302 formed at the lower part of the lighthouse 30, and the base concrete 20 is opened by operating a remote control while the anti-theft door 50 is opened on the lighthouse entrance 302 side. ) can be further installed.
