The present invention relates to a railing installed at the edge of a park road, a walkway or a bridge, and more particularly, to a prefabricated railing in which a wooden pillar and a metal pillar are coupled to each other.

In landscaping facilities, railings are installed on parks, trails, and on the roadsides around lakes to prevent pedestrians from falling or leaving pedestrian paths. Such railings have been mainly used wood in the past, due to the nature of the wood material has a disadvantage that the warpage occurs, such as shrinkage or expansion over time and easily damaged by the weather. In order to solve the shortcomings, but also to install a railing of iron or aluminum railings or synthetic plastics, there is a limit that is difficult to use in large quantities in that it is a material that can pollute the environment. Therefore, assembling handrails that combine the pillars of wood and the pillars of metal to complement each other advantages and disadvantages have been developed.

'Natural wood railing column fixing device' of Korean Patent No. 10-1929380, which is a prior art, discloses a column assembly in which a metal reinforcing pipe is inserted into a rectangular wooden column having a central hole. This is more upright than a simple wooden pole, but after a time of installation will cause a problem that the entire square wooden pole of the twist together. In addition, when a part of the wooden pole is damaged, there is a problem that a considerable cost is required for maintenance in that the whole wooden pole needs to be replaced. In addition, there is a limit that can not reduce the external force transmitted to the reinforcement pipe in the event of an external shock or earthquake, the entire railing can be hardness.

Another prior art, 'deck rod railing assembly' of Korean Patent No. 10-1687733 discloses a pillar assembly in which a wooden plate of trapezoidal shape is fitted into each side of a square tube main frame made of metal. It is inevitable that the rust is generated by the weather in that each vertex portion of the metal square tube main frame must be exposed to the outside in order to fit the wooden plate. Considering that the prefabricated railing is normally installed on a park walkway, such a rusted pillar has a problem that greatly hurts the aesthetic appearance of the city, and additional problems such as tetanus may occur when a pedestrian collides with the pillar. If the externally exposed square tube main frame is bent or broken due to impact, high maintenance is required in that the entire pillar assembly needs to be replaced. In addition, the trapezoidal wooden pillars are fitted on each side of the square tube, so it is not possible to reduce the external force or vibration transmitted to the main frame of the square tube. There is a limit.

Another prior art, 'Prefabricated wood railings' of Korean Patent Registration No. 20-0456494 discloses a pillar assembly in which four bonding woods are coupled to a standing portion of a metal material of a cross (+) shape. It is necessary to replace only certain wooden posts that have problems such as breakage or warping since several wooden posts are independently combined, and to place rectangular joining wood in each vertically formed section at the standing cross-shaped point. There is an easy advantage. However, the point where the standing portion has a crisscross (+) shape has a problem in that torque is generated based on the pillar center of the standing portion when the side impact is applied to a portion other than the center of the standing portion. In particular, the shape of the standing portion has a limit that tends to cause deformation because the stress is concentrated in the vertical portion of the two metal plates. In addition, there is a disadvantage that the external force transmitted to the standing portion is not vulnerable to external shock or earthquake in that it can not be reduced.

It is composed of

The main column 21 is a metal pillar formed in a cylindrical shape, and a plurality of rail grooves 211 are formed in the longitudinal direction on the outer circumferential surface thereof. The shareholder 21 is installed upright in the form of a pipe having a hollow, it may be composed of a metal such as aluminum. The main column 21 may be formed in the form of a concentric double tube having a different diameter as shown in FIG. 3 so that the rail groove 211 is formed on the outer circumferential surface thereof.

The stockholder 21 may be strengthened in the uprightness by inserting the inner barrel 22 at its lower end. The inner circumference 22 is composed of a flat base plate 221 and a rod-shaped support core 222 formed perpendicular to the upper surface of the base plate 221. Base plate 221 is composed of a metal plate of steel material, it can be fixed using an anchor or bolt to the concrete foundation embedded in the basement. Alternatively, the base plate 221 may be welded onto a structure disposed at the edge of the bridge.

The support core 222 is formed of a rod-shaped metal column perpendicular to the upper surface of the base plate 221. A representative example of the metal material is steel. Since the support core 222 is inserted and disposed inside the shareholder 21, the cylindrical shape is appropriate, and in order to have enhanced support force, the support core 222 may be formed in a rod shape full of hollow than a hollow tube shape. The diameter of the support core 222 of the main column 22 is formed to be equal to or smaller than the inner diameter of the main column 21, and the support core 222 of the main column 22 is inserted into the main column 21. As described above, since the main column 22 is disposed inside the lower end of the main column 21, the main column 21 may be prevented from being hardened due to external impact or torsion of wood.

The plurality of rail grooves 211 formed on the outer circumferential surface of the main column 21 are formed in the longitudinal direction at positions spaced apart from each other by a predetermined interval on the outer circumferential surface of the main column 21 in the form of a pipe. For example, as illustrated in FIGS. 3-4, each of the rail grooves 211 may be formed in four portions in the east, south, west, and north directions of the outer circumferential surface of the shareholder 21 based on the center of the shareholder 21.

Each of the plurality of wood blocks 23 is coupled to the outer circumferential surface of the stockholder 21, and a portion facing the outer circumferential surface of the stockholder 21 is formed as a curved surface. In brief, the wood block 23 is a wooden column cut into a curved surface in which any corner of the rectangular body is concave. As shown in FIG. 4, each wood block 23 is formed with a curved surface in which three corner portions have a right angle and one remaining portion is concave inward.

 When the plurality of wood blocks 23 are assembled so that each side is in contact with each other, a cylindrical space is formed at the center thereof. The space of the cylinder is a portion in which the pipe-shaped shareholder 21 is placed, and the curvature of the curved surface of the wooden block 23 should be determined and manufactured in consideration of the curvature and the diameter of the shareholder 21. In particular, when the curvature of the curved surface of the wood block 23 is the same as the curvature of the outer circumferential surface of the shareholder 21, preventing the external exposure of the shareholder 21, which is a metal material, rust or damage due to environmental factors such as weather and rain Can be prevented.

The adapter 24 is vertically fitted into the rail groove 211 of the stockholder 21, and is coupled to each curved surface of the plurality of wood blocks 23. Due to the structure in which the adapter 24 coupled with the wood block 23 is fitted into the rail groove 211 of the shareholder 21, when the impact is applied laterally to the pillar assembly 20, the adapter 24 is laterally oriented. Squeezes into, reducing impact. In addition, the rail groove 211 portion of the shareholder 21 is also elastically restored to provide a reaction force to the side impact can reduce the external impact. In addition, even if the external force is applied in a direction away from the shareholder 21, the wooden block 23 is fitted with the shareholder 21 and the adapter 24, it is possible to reduce the external force by generating a resistance to be restored. That is, in the present embodiment, the adapter 24 and the main column 21 are fitted to each other, thereby reducing the external force or impact applied laterally of the column assembly 20, so that the wooden block 23 and the main column 21 are coupled to each other. Can be maintained.

Specifically, the adapter 24 has a flat cross-section formed in the shape of "H" so that the guide grooves 241 are formed on both sides thereof and is fitted into the rail grooves 211 of the main column 21. Therefore, even if the wooden block 23 receives an external force in a direction away from or close to the shareholder 21, both side portions of the adapter 24 fitted into the rail groove 211 of the shareholder 21 exert elasticity and Significantly reduce

The adapter 24 may be formed in one rectangular shape that is as long as the height of the wood block 23 and may be assembled to the entire rail groove 211 formed in the curved portion of the wood block 23. Alternatively, the adapter 24 may be formed of a plurality of square pieces and assembled into a plurality of rail grooves 211 formed in the curved portion of the wood block 23.

In particular, when the adapter 24 is made of an elastic material such as rubber, the wooden block 23 may first reduce the external shock transmitted to the shareholder 21 and the adapter 24 may reduce the secondary. Therefore, it is possible to greatly reduce the external shock transmitted to the shareholder 21 to prevent the accident that the shareholder 21 may be hardened by the external shock.

A mounting groove 231 into which a part of the adapter 24 is inserted is formed in the curved portion of the wood block 23. The adapter 24 is partially inserted into the mounting groove 231 of the wood block 23 and then fixed to the curved surface of the wood block 23 with a bolt penetrating through the center. The mounting groove 231 should determine the depth of the groove in consideration of the portion where the guide groove 241 of the adapter 24 is formed so that the rail groove 211 is not interfered with the guide groove 241 of the adapter 24. do. As shown in Figure 4, the mounting groove 231 is formed to correspond to the portion of the adapter 24 is inserted so that one side portion of the adapter 24 is closely inserted. When the wooden block 23 receives an external impact in the rotational direction, the adapter 24 inserted into the mounting groove 231 may generate a strong reaction force, thereby greatly reducing the external impact. The adapter 24 may be formed with a bolt guide hole 242 so that the bolt easily penetrates the center of the adapter 24 to be penetrated through the wood block 23 using a bolt.

In addition, a shock absorbing member 25 is inserted into the portion where each of the plurality of wood blocks 23 is in contact with each other. The wood block 23 is formed with a buffer inserting groove 232 to insert the buffer member 25 in contact with each other. Representative examples of the buffer member 25 is a synthetic resin material. The buffer insertion groove 232 is preferably formed as a locking step as shown in Figure 4 one buffer member 25 is preferably caught on two adjacent wooden blocks (23). This structure has the first advantage of beautiful appearance of the assembly railings, and due to the compression of the cushioning member 25 during expansion between adjacent wood blocks 23 can prevent the breakage of the wood block (23) There is a third advantage, there is a third advantage that can maintain a firm coupling state even when assembling a plurality of wood blocks 23 by preventing the separation of the adjacent wood block (23).

The cover part 26 covers the upper part of the shareholder 21 and the wood block 23 to prevent rain, fallen leaves, and dust from entering the inside of the pillar assembly 20. The cover part 26 may be typically made of plastic, and manufactured to correspond to the shape of the wood block 23.
