The present invention relates to a leveling post for a raised floor used for a raised floor of a building and a raised floor installation structure including the same.

In general, a double-floor structure is an architectural structure used in a clean room, a computer room, and the like, which requires a large area and height of a lower space. In the double floor, pillars are installed from the floor of the building, lattice beams arranged horizontally and vertically crosswise are installed on the pillars, and crossbeams arranged in one direction are installed on the lattice beams. And by attaching a raised floor panel on the crossbeam, a space is secured between the floor and the raised floor. Various cables such as electric wires are located in this space.

At this time, a leveling post for combining the grid beam and the cross beam is provided between the grid beam and the cross beam. The leveling post serves not only to combine the two components, but also to adjust the height of the crossbeam to maintain the horizontality of the crossbeam, thereby adjusting the spacing between the lattice beam and the crossbeam. Leveling posts must be formed to have sufficient rigidity to withstand large loads including crossbeams and raised floor panels.

The conventional leveling post was manufactured in the form of attaching four bolts to one base. The conventional leveling post formed with such a simple structure has the advantage of being easy to manufacture and installing and inexpensive because it can sufficiently withstand a relatively low load. However, in order to withstand a relatively high load, the diameters of bolts and nuts must be increased Accordingly, there is a problem of interference between the nut and the fastening tool. In addition, there is a problem that the weight and manufacturing cost of materials increase according to the enlargement of bolts and nuts, and it is difficult to have sufficient rigidity for loads in the horizontal direction rather than in the vertical direction (gravity direction). In the end, it was inappropriate to apply a high load from multiple directions.

Accordingly, an object of the present invention is to provide a leveling post for a raised floor that can withstand loads applied in various directions, is easy to assemble, and has a convenient height adjustment, and a raised floor installation structure including the same.

In this case, the upper socket and the lower socket may include: a base in which the fastening hole is formed; a boss part extending in one direction from the base part and having a thread formed on an inner circumferential surface; and a plurality of ribs protruding from an outer peripheral surface of the boss and one surface of the base.

In addition, the plurality of ribs may be disposed to be spaced apart from each other, and the fastening hole may be formed between the plurality of ribs.

In addition, in the upper socket or the lower socket, a hole is formed in the boss portion, and a fixing means is fastened to the hole to contact the outer circumferential surface of the pipe, thereby preventing rotation of the pipe.

In addition, a hole for rotating the pipe may be formed in the middle portion of the pipe.

In addition, the hole for rotating the pipe may be formed in pairs to face each other based on the center of the pipe.

On the other hand, according to another aspect of the present invention, the first beam is spaced apart from the floor, a plurality of intersecting arrangement; a second beam disposed in one direction on top of the first beam; and a raised floor panel coupled to an upper portion of the second beam, wherein a plurality of leveling posts for the raised floor are coupled at regular intervals between the first beam and the second beam, and the leveling posts for the raised floor include: a pipe having threads formed in opposite directions at the upper and lower sides; an upper socket positioned on the upper side of the pipe and having a thread formed on an inner circumferential surface into which the pipe is inserted; and a lower socket located at the lower side of the pipe and having a thread formed on an inner circumferential surface into which the pipe is inserted, a plurality of fastening holes are formed in the upper socket and the lower socket, and at least one of the upper socket and the lower socket has A pipe anti-rotation means is provided, the upper socket is coupled to the second beam, and the lower socket is coupled to the first beam.

[First embodiment]

Hereinafter, a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a leveling post for a raised floor according to a first embodiment of the present invention, FIG. 2 is a front view of FIG. 1, FIG. 3 is a cross-sectional view of FIG. 2, and FIG. FIG. 5 is a plan view showing the lower socket of FIG. 1 , and FIG. 6 is a cross-sectional view taken along line A-A of FIG. 5 .

As shown in these drawings, the leveling post 100 for a raised floor according to the first embodiment of the present invention includes a pipe 110 , an upper socket 120 , and a lower socket 130 .

The pipe 110 has a cylindrical shape in which threads are formed on the upper and lower outer peripheral surfaces, respectively. The upper thread 114 and the lower thread 116 are formed in opposite directions to each other. For example, the upper screw thread 114 may be a right-turn screw, and the lower screw thread 116 may be formed as a left-turn screw, respectively. Although the pipe 110 has a hollow cylindrical shape, it is also possible to change to a solid cylindrical shape in consideration of rigidity and the like.

A hole 112 for pipe rotation is formed in the middle of the pipe 110 . The pipe rotation hole 112 is formed in pairs to face the center of the pipe 110 . The operation of rotating the pipe 110 requires considerable precision, but when an operator directly grips and rotates the pipe 110, it is difficult to accurately rotate the pipe 110 by a required angle. Accordingly, a tool such as a metal rod having a diameter smaller than that of the pipe rotating hole 112 may be passed through the pipe rotating hole 112 to rotate the pipe 110 by a desired angle through the tool.

The upper socket 120 and the lower socket 130 are respectively coupled to the upper end and the lower end of the pipe 110 . Specifically, the pipe 110 is inserted into the upper socket 120 and the lower socket 130 , and the threads formed on the outer peripheral surface of the pipe 110 and the upper socket 120 and the lower socket 130 . The threads formed on the inner circumferential surface of the are engaged by engaging with each other.

The upper socket 120 includes a plate-shaped base portion 122 , a boss portion 124 protruding cylindrically from the base portion 122 , and surrounds the boss portion 124 until the base portion 122 . and a plurality of ribs 126 extending therefrom.

An empty space for inserting the pipe 110 is formed in the center of the base portion 122 in a circular shape, and a plurality of fastening holes 122a are formed outside the circular space. The fastening hole 122a is a portion into which a bolt for coupling the upper socket 120 with a second beam 400 to be described later is inserted.

The boss part 124 is formed in a cylindrical shape protruding from one surface of the base part 122 . A thread is formed on the inner circumferential surface of the boss part 124 so that it can be screw-coupled to the pipe 110 .

The rib 126 is formed to protrude from the outer peripheral surface of the boss part 124 . The rib 126 is integrally formed from the outer peripheral surface of the boss part 124 to one surface of the base part 122 , but the protruding length gradually increases toward the base part 122 . The rib 126 serves to reinforce the upper socket 120 so that it is not damaged or deformed.

Specifically, as shown in FIG. 4 , a plurality of the ribs 126 are disposed to be spaced apart from each other in the circumferential direction with respect to the center of the base part 122 . The rib 126 is formed smaller than the main rib 126b between the main rib 126b disposed adjacent to the fastening hole 122a and the main rib 126b, and It includes a sub-rib 126a disposed perpendicular to one surface.

The rib 126 is formed to be symmetrical with respect to the center point of the base part 122 . As seen from the drawings, the main rib 126b crosses the center of the base part 122 in an X-shape, and the fastening hole 122a is positioned between the two adjacent main ribs 126b. do. In order to secure the diameter of the fastening hole 122a and the working space of the fastening tool, the adjacent main ribs 126b have an angle of approximately 35 degrees.

Since four fastening holes 122a are formed in the base part 122, a total of eight main ribs 126b are formed on both sides of the fastening hole 122a, respectively. The sub-ribs 126a are disposed between the main ribs 126b and serve to assist the main ribs 126b, and the number or position of the sub-ribs 126a depends on the magnitude of the load or the size and shape of the base part 122 . can be appropriately determined. 4 and 5 , two sub-ribs 126a are formed in the upper socket 120 , and four sub-ribs 136a are formed in the lower socket 130 . However, this is only an example, and the number and position of the sub-ribs formed in the upper socket 120 and the lower socket 130 may be the same.

As shown in FIG. 5 , the lower socket 130 has a generally similar shape to the upper socket 120 , a plate-shaped base part 132 , and a boss part 134 cylindrically protruding from the base part 132 . ), and a plurality of ribs 136 that surround the boss part 134 and extend to the base part 132 . For convenience, a description overlapping with the upper socket 120 will be omitted, and differences between the lower socket 130 and the upper socket 120 will be mainly described.

A fastening hole 132a is formed in the base 132, and a fastening hole boss 132b surrounding the fastening hole 132a is formed to protrude. The fastening hole boss 132b corresponds to a portion where the base part 132 is reinforced in response to the stress concentrated around the fastening hole 132a. Typically, since the lower socket 130 receives a greater load than the upper socket 120 , the fastening hole boss 132b is formed only in the lower socket 130 in this embodiment. However, a configuration such as the fastening hole boss 132b may also be formed in the upper socket 120 if necessary.

Referring to FIG. 6 , a hole 134b for preventing pipe rotation is formed in the boss part 134 . A screw 134a is coupled to the pipe rotation preventing hole 134b, and the end of the screw 134a is pressed while in contact with the pipe 110 to prevent rotation of the pipe 110 by frictional force. The pipe rotation preventing hole 134b and the screw 134a serve as the pipe rotation preventing means to prevent unintentional rotation of the pipe 110 .

The process of assembling and adjusting the height of the leveling post 100 for a raised floor according to the present embodiment will be described.

First, the upper and lower portions of the pipe 110 are inserted into the upper socket 120 and the lower socket 130 . As described above, since they are screwed together, the pipe 110 may be rotated and inserted. Alternatively, rotating the upper socket 120 and the lower socket 130 while fixing the pipe 110 may also be performed. It is possible.

When the pipe 110 is rotated in one direction, the distance between the upper socket 120 and the lower socket 130 is increased, and when the pipe 110 is rotated in the opposite direction, the upper socket 120 and the lower socket 130 are rotated in the opposite direction. The distance between the lower sockets 130 becomes closer. The height of the present embodiment can be adjusted by rotating the pipe 110 in a desired direction using the pipe rotation hole 112 formed in the pipe 110 .

After the intended height adjustment is completed, the screw 134a is inserted into the pipe rotation preventing hole 134b so that the pipe 110 is no longer rotated in any direction. The screw 134a corresponds to the fixing means of the pipe. At this time, it is preferable that the screw 134a strongly presses the pipe 110 so that the screw 134a is sufficiently deeply coupled so that the pipe 110 is completely fixed.

Hereinafter, operational effects of the leveling post 100 for a raised floor according to the present embodiment will be described.

In the leveling post 100 for a raised floor according to the present embodiment, not only a vertical load but also a lateral load close to the horizontal direction acts. In order to secure sufficient rigidity against such lateral load, the present embodiment prevents phenomena such as inclination of the pipe 110 or bending of the boss portions 124 and 134 by forming the ribs 126 and 136. . That is, since the ribs 126 and 136 are symmetrically disposed on the outer circumferential surfaces of the bosses 124 and 134 to compensate for the thickness of the bosses 124 and 134 , the upper socket 120 and the Prevent the lower socket 130 from being deformed or damaged.

In addition, since the pipe 110 can be easily and precisely rotated using the pipe rotation hole 112 , the height adjustment operation is simple.

In addition, since the pipe 110, the upper socket 120, and the lower socket 130 are fastened by screw coupling, the assembly operation is simple.

[Second embodiment]

Hereinafter, a second embodiment of the present invention will be described in detail with reference to the accompanying drawings.

7 is a perspective view illustrating a leveling post for a raised floor according to a second embodiment of the present invention, FIG. 8 is a front view of FIG. 7, FIG. 9 is a plan view of the upper socket of FIG. It is a plan view showing the lower socket.

This embodiment is partially modified so that it can withstand a higher load than the above-described first embodiment. For convenience, descriptions of parts common to the first embodiment will be omitted.

The leveling post 200 for a raised floor according to the present embodiment includes a pipe 210 , an upper socket 220 , and a lower socket 230 .

The pipe 210 has a shape similar to that of the first embodiment, but has a larger diameter to support a higher load.

The upper socket includes a base portion 222 , a boss portion 224 , and a rib 226 . A plurality of fastening holes 222a are formed in the base portion. A rib 226 is disposed adjacent to the fastening hole 222a. At this time, the rib 226 is spaced apart from the fastening hole 222a by a predetermined distance. This is because a bolt is inserted into the fastening hole 222a and the bolt is rotated using a tool to couple it, so a free space for the tool is required in this operation. For this reason, as shown in FIG. 9 , the boss part 224 corresponding to the vicinity of the fastening hole 222a is rounded.

The lower socket 230 includes a base portion 232 , a boss portion 234 , and a rib 236 . A plurality of fastening holes 232a are formed in the base portion 232 . The base part 232 of the lower socket 230 is different from the base part 222 of the upper socket 220 in that it is formed in a larger square shape. This is because the first beam 300 to which the lower socket 230 is coupled is formed to have a relatively large width, so sufficient space is secured, but the width of the second beam 400 to which the upper socket 220 is coupled is the This is because it is smaller than the width of the first beam 300 . A detailed description of the coupling relationship with the first beam 300 and the second beam 400 will be described later.

As shown in FIG. 8 , a screw 234a is coupled to the boss 234 in the lower socket 230 . Although similar pipe rotation prevention means were provided in the first embodiment, in this embodiment, the diameter of the pipe 210 is further enlarged to support a higher load, so the size of the screw 234a is also the size of the screw 234a in the first embodiment. can be made larger.

9 and 10 , the upper socket 220 and the lower socket 230 are different from the first embodiment in the number and arrangement of ribs 226 and 236 .

In this embodiment, a total of eight ribs 226 and 236 are formed in the upper socket 220 and the lower socket 230 so as to have four fastening holes therebetween. This is equivalent to omitting the sub-rib in the first embodiment. That is, the configuration such as the sub-rib has been deleted due to the enlargement of the diameter of the pipe 210 and the spatial limitation due to the limited size of the base parts 222 and 232 .

However, by ensuring the protruding thickness of the ribs 226 and 236 and arranging the plurality of ribs 226 and 236 to be radially symmetrical, deformation due to lateral load can be prevented without sub-ribs.

[Third embodiment]

Hereinafter, a third embodiment of the present invention will be described in detail with reference to the accompanying drawings.

11 is a perspective view illustrating a raised floor installation structure according to a third embodiment of the present invention, FIG. 12 is a front view of FIG. 11 , and FIG. 13 is a side view of FIG. 11 .

The raised floor installation structure according to the present embodiment includes a first beam 300 , a second beam 400 , a leveling post 100 for a raised floor, and a raised floor panel 500 .

The first beam 300 is spaced apart from the floor of the building. Although not shown, pillars are installed on the floor, and the first beams 300 may be arranged to cross in a lattice structure on the top of the pillars. 11 to 13 illustrate only a portion of the first beams 300 arranged in a lattice structure arranged in parallel.

The first beam 300 is also referred to as a lattice beam, and is formed of concrete or steel depending on the characteristics of the building structure or the purpose of the raised floor. In the case of a steel material, an H-beam may be used.

A leveling post 100 for a raised floor is coupled to the upper surface of the first beam 300 . The leveling post 100 for the raised floor is the same as described above in the first embodiment, but the second embodiment may be applied if necessary.

In the leveling post 100 for the raised floor, the lower socket 130 is coupled to the first beam 300 , and the upper socket 120 is coupled to the second beam 400 .

The second beam 400 is also referred to as a cross beam, and a plurality of beams are arranged in parallel in one direction. The distance between the second beams 400 is equal to the length of the raised floor panel 500 .

Since the raised floor panel 500 serves as the second floor of a space to which a raised floor structure is applied, such as a clean room or a computer room, a precise level must be maintained. In order to level the raised floor panel 500 , the second beam 400 must be leveled, and this is achieved by adjusting the length of the leveling post 100 for the raised floor.

In the above, embodiments of the present invention have been described with reference to the accompanying drawings, but the technical configuration of the present invention can be changed to other specific forms by those skilled in the art to which the present invention pertains without changing the technical spirit or essential features of the present invention. It will be appreciated that this may be practiced. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
