Description

Improved type of prefabricated pillar using extruded bars {ADVANCED TYPE ASSEMBLY PILLAR}

The present invention relates to a prefabricated pillar, in which steel is placed on the inside and decorative materials such as wood are assembled on the outside of the steel, so that it is not only durable but also has a beautiful appearance.

In outdoor areas such as parks, rest areas, and children's play areas, many pergolas consisting of shade and pavilions are installed to avoid sunlight and allow people to relax. However, not only is this pergola difficult to manufacture and install, but it also costs a lot of money. Recently, a prefabricated form that is made using lightweight materials and can be made and installed elsewhere or made and installed directly on site is being provided.

In particular, recently, as eco-friendly and well-being products have been in the spotlight, wood materials or materials with a wood-like feel are often used to make the appearance of the pergola more beautiful. Ho 'Installation structure of decorative reinforcing wood for pergola columns' involves erecting a column and installing reinforcing wood on the outer surface of the column to prevent corrosion and enhance the appearance. Although the fixing bolts that secure the reinforcing wood are not exposed to the outside, What secures the reinforcing wood is a fixture, and since the fixture is fixed to the column by a fixing bolt, erecting the reinforcement wood only by relying on the bonding force of the fixing bolt results in shortening the durability of the column. In addition, in the above utility model, there are more parts that are not visible than parts that are visible to the outside, so it is impractical and has the disadvantage of being difficult to assemble even if it is prefabricated.

In addition, in addition to the above utility model, there were products that made pillars by assembly in the form of fitting rather than the joining force of bolts, but these products were made by chamfering or making grooves in the part corresponding to the reinforcement wood and processing both ends at an angle, etc. This caused an increase in production costs because it required a lot of processing.

The present invention was invented to solve the problems of the prior art as described above. Decorative materials are placed on the outside for a beautiful appearance, and steel materials are placed on the inside to ensure excellent durability. The structure of the pillar is made by inserting rather than the joining force of bolts. The purpose is to provide a pillar that can be assembled into a matching form.

In addition, the purpose is to provide a pillar that enables prefabricated construction using simple decorative materials.

Additionally, the purpose is to provide a pillar with a structure that is not easily damaged when combined with a decorative material.

The prefabricated column of the present invention for achieving the above object includes a pipe 110 located on the inside, a plurality of support plates 120 located in close contact with the outside of the pipe and fastened to each other to surround the pipe, It includes decorative materials 130 each fastened to the outside of the support plate and a finishing material 150 that is inserted into the gap between the decorative materials 130 and the decorative materials 130 to close the gap, and is located at the end of the prefabricated pillar 100. A frame 140 is positioned with a hollow hole through which the pipe can pass, and a bolt penetrates the frame 140 and is fastened to an end of the decorative material 130.

The support plate 120 is bent outward at both ends in the width direction, and one end of the support plate 120 is bent once more in the inward direction to form a receiving groove 121 therein, and the receiving groove 121 is formed at the other end. A coupling blade 122 that can be inserted into the groove is formed.

The angle at which both ends of the support plate 120 are bent is 45 degrees, and first and second fastening pieces 191.124 are formed behind the receiving groove 121 and protrude on both sides. The first and second fastening pieces have Each of the support protrusions 301 protrudes vertically from the first and second fastening pieces 191.124 toward the support plate 120, thereby restricting the movement of the decoration material 130 in the width direction when the decoration material 130 is coupled.

A support 302 protrudes from the surface of the support plate 120 facing the first and second fastening pieces to limit movement of the decoration material 130 in a direction perpendicular to the width direction of the decoration material 130 when the decoration material 130 is coupled. do.

The support ledge 302 is shaped like an 'L' so that the force received by the support ledge 302 can be distributed and received.

One end of the support protrusion 302 is extended toward the support protrusion 301 to form an extension protrusion 303 so that the extension protrusion 303 faces the support protrusion 301.

A support protrusion 304 is formed next to the extension protrusion 303. The support protrusion 304 extends from the end of the support protrusion 302 in either direction of the coupling blade or the receiving groove. The end of the support protrusion 304 is It is formed at an angle so that even if it is pushed by a heavy decorative material, it is supported by contacting the wall forming either the coupling blade or the receiving groove.

As previously explained, the prefabricated pillar of the present invention has the advantage of having a beautiful appearance due to the decorative material located on the outside and excellent durability due to the steel pipe and support plate assembled on the inside.

In addition, the prefabricated pillar of the present invention has the advantage of preventing the decorative material from being twisted even when installed outdoors as the decorative material and the steel material are fastened in the longitudinal direction.

In addition, the prefabricated pillar of the present invention not only has a more beautiful appearance by closing the gap between the decorative material and the decorative material, but also improves durability by blocking foreign substances from entering between the decorative material and the steel material, and also has the advantage of being clean and not messy. there is.

In addition, it has the effect of providing a prefabricated pillar that is easy to assemble and lightweight while providing excellent aesthetics.

Even if heavy decorative materials are used, it has the effect of providing a prefabricated pillar that is not easily damaged by the decorative materials.

1 to 4 are diagrams showing a prefabricated pillar according to an embodiment of the present invention.
Figure 5 is a view showing a conventional prefabricated pillar

Below, preferred embodiments of the prefabricated pillar according to the present invention will be described in detail with reference to the attached drawings.

As shown in FIG. 1, the prefabricated pillar 100 is a square pillar, including a square tube 110 located inside, a support plate 120 positioned in close contact with each side of the square tube 110, and the It includes a decorative material 130 fastened to the support plate 120 and a finishing material 150 located between the decorative material 130 located on the four sides and closing the space between the decorative material 130 and the decorative material 130.

As shown in the drawing, the square tube 110 is located at the innermost part. The square tube 110 is preferably made of aluminum alloy or stainless steel, which has excellent corrosion resistance and is light.

Meanwhile, support plates 120 are located on each of the four outer sides of the square tube 110. The square tube 110 is located at the center and the support plate 120 is attached to the four sides. The outer surface of the support plate 120 is so that the protrusion 123 of the support plate 120 is inserted into the second groove 131 of the decoration material 130. Place the decoration material 130 in the first groove 131 of the decoration material 130 and fasten the first bolt 127 to fix the support plate 120 and the decoration material 130.

With the decoration material 130 fixed to the support plate 120 in this way, the support plate 120 is attached to each of the four sides of the square tube 110, and a receiving groove 121 is formed at one end of the support plate 120. A coupling blade 122 is formed at the other end, and the four support plates 120 are connected in a square manner by inserting the coupling blade 122 of the other support plate 120 into the receiving groove 121 of the support plate 120.

Then, when the four support plates 120 are connected to each other and fixed in a square shape, the square frame 140 is inserted into both ends of the square tube 110 and the second bolt is inserted into the hole formed in the square frame 140. 2 Fasten the bolts to the top and bottom of the decoration material 130, respectively. Then, the four decorative materials 130 to which the square frame 140 is connected are stably fixed.

Next, when the latch 151 of the finishing material 150 is inserted between the four assembled decoration materials 130, the closing plate 153 of the finishing material 150 closes the gap between the decorative materials 130, thereby forming a support plate ( 120) will not be exposed.

It is good to use light decorative materials, but if you use something like solid wood to create a wooden feel, not only will the final product weigh a lot, but it will also increase the cost by filling every corner of the interior with solid wood even though it is not necessary. do. Therefore, separating the decorative material and the support plate 120 as shown in Figure 2 can reduce costs and facilitate assembly and installation. In addition, instead of the decorative material 130 and the support plate 120 being spaced apart, the first and second fastening pieces hold them on both sides and the first bolt holds them in the center, so the connection does not break down.

In addition, the decorative material was made based on a square plate and simple grooves were made at both ends and the center, so that the decorative material required minimal processing, making it easy to manufacture and reducing manufacturing costs.

In addition, the first groove 131 allows the head of the first bolt 127 to be located within the first groove 131 when the first bolt 127 penetrates the support plate 120 and is fastened to the decoration material 130. Therefore, when the support plate 120 is in close contact with the square tube 110, the head of the first bolt 127 does not contact the square tube 110, and the support plate 120 is in close contact with the square tube 110, thereby ensuring a firm connection. Make it possible. The first bolt 127 is preferably made of stainless steel with excellent corrosion resistance.

The support plate 120 described above has a complex formation, so it is preferable to manufacture it by extrusion. As shown in the drawing, both ends of the support plate 120 in the width direction are bent outward, and one end is bent outward. It is bent once more in the inward direction to form a receiving groove 121 on the inside in the bending direction, and the other end is a coupling blade 122 that can be inserted into the receiving groove 121 in an unfolded state without being bent. form

Here, the angle at which both ends of the support plate 120 are bent is 45 degrees, and from the part bent to form the receiving groove 121 to the back of the receiving groove, a second fastening piece 191 and a first fastening piece ( 124) is formed to protrude at an angle of approximately 90 degrees around the receiving groove 121.

Support protrusions 301 are formed on the first, second, and fastening pieces 191 and 124, and support protrusions 302 are formed on the surface of the support plate 120 facing the first and second fastening pieces. The expression of facing each other refers to the case where four support plates 120 are combined with reference to Figure 3. The support protrusion 301 limits the movement of the decoration material 130 in the same direction as the width of the decoration material 130, and the support protrusion 302 moves in a direction perpendicular to the width of the decoration material 130 while supporting the decoration material 130. limit things. In other words, support it to prevent it from going deeper.

In Figure 5, which shows the conventional structure, the first support piece 193 and the second support piece 194 are formed on the coupling blade 122 and the receiving groove 121, and 'ㄱ' or 'ㄴ' are formed at their ends, respectively. A 'shaped support plate 195 is formed, and when the decorative material 130 is combined, the direction of the force applied to the decoration material is misaligned, and the support plate 195 or the first and second support pieces 193 and 194 are often broken. In particular, since the support plate 120 is formed at an angle from the coupling blade 122 and the receiving groove 121, it is often damaged by external force even when the support plate 120 is stored separately. In Figure 5, when the decoration material 130 is pushed in the direction a, the first support piece 193 does not support the decoration material and supports only one part of the support plate 195, so if excessive force is applied, the support plate 195 may be broken. Even when pushed in direction b, the first support piece 193 cannot support the direction of the arrow and the support plate 195 must receive all the force. Therefore, if excessive force is applied, the support plate 195 may break. . In addition, since the support plate 195 is formed at the end of the first support piece 193, the longer the length of the first support piece 193, the greater the torque proportional to the length at the end of the first support piece 193. Because it got caught, it could break more easily.

This is the same for the second support piece 194 formed on the coupling blade 122. Since the support plate 195 is spaced apart from the coupling blade 122 by the length of the second support piece 194, when force is applied in the d direction to the support plate 195 formed in the shape of 'L', the second support piece 194 There is a possibility that it may break, and if force is applied in the c direction, there is a high possibility that the support plate 195 will fall off. The decorative material 130 is often light, but the more high-quality the decorative material is, the heavier it is, and excessive force may be applied during attachment or combination, so the length of the first and second support pieces 193 and 194 The longer the length, the easier it is for the first and second support pieces 193 and 194 and the support plate 195 to be damaged.

In order to overcome the disadvantages described above, the present invention forms a support ledge and a support projection to sufficiently support the weight given to the decoration material 130. Unlike the prior art, nothing is formed on the coupling blade, coupling blade 122, and receiving groove 121, and short support protrusions 301 are formed on the first and second fastening pieces 191 and 124, and on the main body side of the support plate 120. Forms a support 302. The support protrusion 301 briefly protrudes from the first and second fastening pieces 191 and 124 and serves to prevent the decorative material 130 from moving in the horizontal direction when coupled (the uppermost decorative material in Figure 3 ( 130), the left and right longitudinal directions are set to the horizontal direction and explained)) Even if the length of the support protrusion 301 is formed short, the length is not a big problem because it serves to limit the space for moving in the horizontal direction. Rather, the length is short. The torque is proportional to the length, and even if decorative materials of the same weight are used, the length of the protrusion 301 is short, so the torque applied is small and the probability of damage is correspondingly small.

A support 302 is formed on the main body of the support plate 120. The support 302 protrudes vertically from the main body of the support plate 120 and serves to support the decoration material 130. When viewed from the decorative material 130, the horizontal movement of the decorative material 130 is limited on both sides by the supporting protrusions 301, and the vertical movement is limited by the supporting protrusions 302.

In the past, the support plate 195 was made into an 'L' shape to limit vertical and horizontal movement of the support plate 195, but the protruding first and second support pieces 193 and 194 applied vertical and horizontal forces together. Because I received it, it could easily break. In the drawing, the length of the second support piece 194 or the length of one side of the support plate 195 is long, which can cause damage even if the decoration material 130 is installed slightly incorrectly.

However, in the present invention, the short support protrusion 301 and the short support ledge 302 are short in length to prevent the decoration material 130 from being easily damaged while restricting the movement of the decoration material 130 in the horizontal and vertical directions.

Meanwhile, a gap is formed between the four square decorative materials 130, that is, at the four corners of the prefabricated pillar 100, by the bent ends of the support plate 120. The finishing material 150 is located in this gap to block exposure of the support plate 120. The finishing material 150 includes a pair of latches 151 sandwiched between the two decorative materials 130, and a closing plate that connects the pair of latches 151 and closes the gap between the two decorative materials 130 ( 153). Here, the pair of latches 151 include finishing fastening pieces 196 and 197 and latch 151 that protrude obliquely outward from the first and second fastening pieces protruding outward of the support plate 120, as shown in FIG. 3. ), the latch fastening pieces (198, 199) protruding inward meet each other and prevent either the finishing fastening piece or the latch fastening piece from moving left or right by being caught on the other side.

In addition, both ends of the latch are bent inward to close the gap between the two decorative materials 130 so that they are not visible when viewed from the bar side.

Previously, the prefabricated pillar 100 was described as being composed of a square, but it can be composed of not only triangular, pentagonal, and hexagonal pillars, but also circular pillars. Meanwhile, in addition to wood, decorative materials of various materials such as synthetic resin or MDF, which have a beautiful appearance, can be used.

Figure 4 shows another embodiment, where one end of the support protrusion 302 is extended toward the support protrusion 301 to form an extension protrusion 303 so that the extension protrusion 303 faces the support protrusion 301. As a result, if the decoration material 130 is hard or heavy, it is used to better limit the movement of the decoration material 130 in the width direction. Since the decorative material is held at both the top and bottom at both ends, a stable connection is possible.

A support protrusion 304 extending in a vertical direction may be formed next to the extension protrusion 303. The support protrusion 304 extends from the end of the support protrusion 302 in the direction of the coupling blade. The ends are formed obliquely. This prevents damage by allowing the support protrusion (304) to contact the wall and support it when the extension protrusion (303) is pushed toward the coupling blade or receiving groove when a heavy decorative material is used or the decorative material is pushed during installation.
