Description

Technology Field

[0001] The present invention relates to an eco-friendly material-based access floor system with improved corrosion prevention and load-bearing capacity. More specifically, the system is installed at predetermined height intervals from the floor surface, enabling height adjustment of the flooring material relative to the floor surface. It also secures space for the installation of electrical wires routed to the floor surface and allows for installation at a lower height position, unlike conventional systems installed at a relatively high position relative to the floor surface, thereby enabling various installation environments at construction sites. Furthermore, it strengthens load-bearing capacity along with corrosion prevention of the support panels. Background Technology

[0003] Generally, existing access floor devices required for installing raised flooring for the purpose of wiring are designed to allow the installation of flooring at a height raised from the floor of the site, but in most cases, the flooring is installed at a height raised, for example, more than 40 cm from the floor.

[0004] In other words, the existing access floor device is configured so that the flooring can be installed at a height of, for example, more than 40 cm above the floor. However, as the head part of the access floor device is connected to the support plate, the bolt formed in the center of the head part is inserted into the hole of the support member, which is connected in a vertical structure from the center of the support plate. Consequently, there was a problem in that the flooring could not be installed at a low height of 40 cm or less, which did not meet the diverse conditions of on-site construction.

[0005] Furthermore, since existing accessory floor devices consist almost entirely of steel for the head section, support plate, and support, rust develops due to corrosion over time. Additionally, it has been pointed out that the floor panels fail to maintain flatness due to weak load-bearing capacity, bending downwards under the load and failing to maintain flatness for the flooring material.

[0033] FIG. 1 is a schematic diagram conceptually illustrating the state in which components of an eco-friendly material-based access floor system with improved corrosion prevention and load-bearing capacity according to one embodiment of the present invention are installed on a concrete floor (1); FIG. 2 is a detailed three-dimensional drawing illustrating the separated state of the support plate (100) and the head part (200) shown in FIG. 1; FIG. 3 is a conceptual drawing illustrating the side structure of the floor support panel (300); FIG. 4 is a conceptual drawing illustrating the process of opening the floor material (400) in the upward direction, together with the operation process of the opening guide device (500) accompanying the opening of the floor material (400); FIG. 5 is a conceptual drawing illustrating the process of opening the floor material (400) in the downward direction, together with the operation process of the opening guide device (500) accompanying the opening of the floor material (400).

[0034] An eco-friendly material-based access floor system with improved corrosion prevention and load-bearing capacity according to one embodiment of the present invention may be configured to include, for example as illustrated in Drawings 1 to 5, a support plate (100) that secures support capacity in a concrete floor (1) area, a head portion (200) that is connected in a rotating manner while being inserted into a support member (110) that is connected in a vertical structure at the center of the support plate (100), a floor support panel (300) that supports a load by being installed in a manner where corner portions and boundary portions are seated on the head portion (200), and a floor material (400) that is seated on the top of the floor support panel (300) and used as an indoor floor.

[0035] The above support member (110) is a structure that is joined in a vertical structure at the center of the support plate (100), and has a screw thread formed on its outer surface, with a hole (111) further formed in the longitudinal direction of the support member (110).

[0036] The head portion (200) has a through hole (210) formed in its central portion, and the through hole (210) is structured to form a screw thread and can be inserted into the support (110) and coupled by rotating in a structure that engages with the screw thread formed on the outer surface of the support (110).

[0037] The above-mentioned head portion (200) is structured such that a protrusion (201) is further formed by protruding vertically upward from the disc-shaped portion and integrated into a cross-shaped structure, and the above-mentioned protrusion (201) is a portion where each corner of the floor support panel (300), which will be described later, is aligned and seated.

[0038] In addition, the above-mentioned hole (111) formed in the above-mentioned support member (110) can be joined in a structure in which a bolt part (220) is inserted and rotated, and the above-mentioned bolt part (220) is inserted into the above-mentioned hole (111) formed in the above-mentioned support member (110) through a through hole (210) formed in the above-mentioned head part (200).

[0039] Accordingly, the head portion (200) can be inserted up to the length direction of the support (110) by a predetermined thickness, and the bolt portion (220) is inserted through the through hole (210) of the head portion (200) up to the hole (111) formed in the support (110). Since the floor material (400) on which the corner and boundary portions are seated in the head portion (200) can be installed at a low height position, for example, within 40 cm from the concrete floor (1), and since the spatial height between the concrete floor (1) and the floor material (400) can be adjusted within this range of 40 cm, the floor material can be installed even under various environmental conditions of on-site construction.

[0040] That is, the installation of the flooring material (400) can be accommodated even in the diverse conditions of on-site construction where the flooring material (400) could not be installed by raising it to a low height of 40 cm or less.

[0041] Meanwhile, the support plate (100), the head part (200), the floor support panel (300), and the flooring material (400) may utilize reinforcing fibers as an eco-friendly material. These reinforcing fibers are composite materials synthesized from glass fibers, carbon fibers, and aramid fibers, which are used to increase the strength and durability of materials such as plastic and concrete. They are lightweight, strong, and resistant to corrosion.

[0042] That is, since the surface area of ​​the support plate (100), the floor support panel (300), and the flooring material (400) is exposed to moisture, a glass fiber material that is resistant to corrosion and can strengthen support strength may be used. Such glass fiber is, for example, a glass fiber reinforced plastic (FRP) material, which is a material combining glass fiber and plastic, and is lightweight, strong, and resistant to corrosion.

[0043] The head portion (200) may be made of carbon fiber material, wherein the carbon fiber is a carbon fiber reinforced plastic (CFRP) material that uses carbon fiber as a reinforcing material, is lighter than steel and has higher rigidity, has excellent electrical conductivity and wear resistance, and is suitable for applications requiring high rigidity and strength.

[0044] And, as a component of the support plate (100), the support member (110) has a structure including a hole (111) that has a screw thread formed on the outer surface and a screw thread formed inwardly along the length, and as a component of the head part (200), the through hole (210) that has a screw thread formed in the central part and the bolt part (220) that is inserted from the through hole (210) to the hole (111) may be made of aramid fiber material, and such aramid fiber has superior strength compared to carbon fiber and has ultra-high strength characteristics with a strength per unit weight that is more than 5 times higher than iron.

[0045] In other words, the above-mentioned aramid fiber is an ultra-high-strength material with a strength per unit weight that is more than five times higher than that of steel, and features heat resistance requiring physical properties even at high temperatures, flame resistance that does not burn easily, and durability that is strong against impact and abrasion, as well as high durability that does not deteriorate over time, lightweight properties that provide excellent protective performance without the burden of weight as it is lighter than steel, and a stable chemical structure and high resistance to chemicals.

[0046] That is, the support (110), which is a structure including a hole (111) that forms a screw thread on the outer surface and an internal screw thread along its length, the through hole (210) that forms a screw thread in the central part of the head portion (200), and the bolt portion (220) that is inserted and connected from the through hole (210) to the hole (111) are preferably made of such an aramid fiber material, because they are core components where the load is concentrated.

[0047] However, since such aramid fiber materials are susceptible to ultraviolet rays and their performance may deteriorate upon prolonged exposure, and because they are highly impermeable to air and may provide a high-humidity environment, they may consist of a coating layer applied to the aramid fiber itself and a moist coating layer applied to the coating layer.

[0048] The above coating layer can perform the function of blocking ultraviolet rays by mixing titanium dioxide (TiO), ceramic, and rosin solution, and the above wet coating layer can be composed in a mixed manner including a solvent, a humectant, a surfactant, and a coating agent.

[0049] That is, in the above wet coating layer, for example, purified water or ethanol may be used as the solvent, for example, glycerol may be used as the humectant, and for example, synthetic wax or polydimethylsiloxane may be used as the coating agent. In particular, the surfactant helps to mix the other components well with each other and helps them adhere effectively to the coated surface.

[0050] Meanwhile, the floor support panel (300) is used for the purpose of supporting the flooring material (400), and since it supports a load that includes not only the flooring material (400) but also office equipment, people, and various devices placed in the indoor space above the flooring material (400), it has a structural feature that strengthens the supporting force in conjunction with the glass fiber reinforced plastic (FRP) material.

[0051] That is, the floor support panel (300) may be composed of load-distributing protrusions (310) that protrude vertically in a downward direction with a predetermined size along the area of ​​the bottom and maintain a predetermined distance (G) from each other, and collection holes (320) formed on the load-distributing protrusions (310) to collect falling debris, including dust, falling from the floor material (400).

[0052] Of course, the gap (G) formed between the load-distributing protrusions (310) may be configured with a structure including a load-absorbing pad (330) and springs (340) inserted between one end and the other end of the load-absorbing pad (330). It is preferable to use a compression coil spring for the spring (340).

[0053] Since one end of the springs (340) is structured to be attached to one end of the load absorption pad (330) and the other end of the springs (340) is structured to be attached to the wall of the load distribution protrusion (310), when the load acting on the floor support panel (300) acts as a load greater than an unexpected load, the load distribution protrusions (310) can spread outward with respect to the collection holes (320). As the load is distributed through the absorption action of the load absorption pad (330) following the compression of the springs (340), the support force of the floor support panel (300) is strengthened, and damage to the floor support panel (300) can also be prevented.

[0054] Meanwhile, a recovery cover panel (350) may be further configured to cover the load-distributing protrusions (310) from the bottom, and the recovery cover panel (350) may be configured to cover a portion of the bottom of the load-distributing protrusions (310), and one end may be attached to one end of the floor support panel (300), and the other end may be connected to the other end of the floor support panel (300) in a hinge-able structure.

[0055] Of course, one end of the above recovery barrier panel (350) is connected to the other end of the floor support panel (300) by a hinge structure, and is connected in a structure including a torsion spring connection structure, so that when the locking on one end is released, it is tilted downward and rotated based on the elastic force of the torsion spring, thereby opening the lower portion of the load distribution protrusions (310). That is, as the lower portion of the collection holes (320) is opened, the falling materials accumulated and loaded in the collection holes (320) can be discharged to the outside while being recovered by the recovery barrier panel (350).

[0056] One end of the above recovery barrier panel (350) is connected to the other end of the floor support panel (300) by a hinge structure, and is connected in a structure including a connection structure of a torsion spring (TS). When the locking on one end is released, it is tilted downward and rotated based on the elastic force of the torsion spring (TS), thereby opening the lower portion of the load distribution protrusions (310). That is, as the lower portion of the collection holes (320) is opened, the falling materials accumulated and loaded in the collection holes (320) can be discharged to the outside while being recovered by the recovery barrier panel (350).

[0057] Meanwhile, flooring materials (400) installed in a structure that rests on the upper part of the floor support panel (300) become the actual floor area of ​​the room. A fire detector for detecting fire may be installed on the lower part of any one of the flooring materials (400), and a separate marking may be displayed on any one of the flooring materials (400) where the fire detector is installed to identify that it is a flooring material with a fire detector installed.

[0058] In addition, in the case of a flooring material (400) with a fire detector installed, it can be automatically opened upward or downward, which allows the flooring material (400) to be automatically opened when, for example, the fire detector malfunctions and is repaired or replaced, thereby making it convenient to open the flooring material (400) for repair or replacement of the fire detector.

[0059] That is, in order to open the floor material (400), the structure may be configured such that an opening guide device (500) is installed at the bottom of the floor material (400). In this case, the floor support panel (300) located at the bottom of the floor material (400) where the fire detector is installed may be configured to form an opening hole that forms a predetermined space in which the opening guide device (500) can be installed. That is, the opening hole may be formed with a generous size that not only functions as a space required for the installation of the opening guide device (500) but also does not hinder or interfere with the operation of the opening guide device (500).

[0060] Of course, for the convenience of explanation, the flooring material (400) shown in Drawings 4 and 5 is a flooring material that has a fire detector installed at its bottom, although it is not shown in the drawings, and the flooring material (400') (400") installed at the adjacent left and right ends of the flooring material (400) is a flooring material that is fixed by installing both ends of a fixing rod (600) at its bottom.

[0061] In addition, so that the above-mentioned fixing rod (600) can be installed at the bottom of the flooring material (400')(400"), the floor support panel (300) corresponding to the bottom of the flooring material (400')(400") may also have a predetermined open hole formed therein having a space for the fixing rod (600) to be installed.

[0062] The above-mentioned opening guide device (500) may be composed of a space (530) formed in the center, as shown in the conceptual diagrams of drawings 4 and 5, and opening guide members (510) (520) formed in the left and right directions and spaced apart from the space (530).

[0063] Of course, each upper portion of the above-mentioned opening guide (510)(520) may have respective receiving grooves (511)(521) formed therein, wherein the receiving groove (511) is formed in the opposite direction to the receiving groove (521).

[0064] In other words, the receiving groove (511) formed at the top of the opening guide (510) is, for example, a structure that is open toward the upper direction, whereas the receiving groove (521) of the opening guide (520) is a structure that is open toward the lower direction.

[0065] And, the opening member (540) mounted on the upper portion of the opening guide members (510) (520) may be configured as a ladder member structure that maintains a predetermined gap, and is a structure including a first rod (541) coupled to one end of the gap of the opening member (540), a second rod (543) coupled to the other end of the gap of the opening member (540), and a third rod (542) coupled between the first rod (541) and the second rod (543) in the middle of the gap of the opening member (540).

[0066] The third rod (542) is a locking structure that is received and mounted in the receiving groove (511) of the opening guide (510), and the second rod (543) is a locking structure that is received in the receiving groove (521) of the opening guide (520).

[0067] And, the receiving grooves (511)(521) of the above-mentioned opening guides (510)(520) may be composed of, for example, the positive (+) and negative (-) poles of a bar magnet which is a magnetic material, and the third rod (542) may be composed of the negative (-) pole, and the second rod (543) may be composed of the positive (+) pole.

[0068] That is, the structure is such that the receiving groove (511) of the opening guide (510) is, for example, the positive (+) of a bar magnet which is a magnetic material, so the third rod (542) of the negative (-) can be attached by magnetism, and the receiving groove (521) of the opening guide (520) is, for example, the negative (-) of a bar magnet which is a magnetic material, so the second rod (543) of the positive (+) can be attached by magnetism.

[0069] And, the above-mentioned opening guide device (500) has a structure in which the rod (551) of the cylinder (550) is coupled to its lower end, and the cylinder (550) can be coupled and fixed in a vertical structure to the concrete floor (1).

[0070] If the above fire detector needs to be repaired or replaced due to a malfunction, the inconvenience of having to manually open the floor material (400) where the above fire detector is installed can be conveniently avoided by operating the above opening guide device (500).

[0071] As illustrated in Figures 4 and 5, the operation process of the above-mentioned opening guide device (500) involves pressing a forward operation button or a reverse operation button required for the operation of the cylinder (550) when repairing or replacing a fire detector due to a malfunction. When the reverse operation button is pressed, for example, the cylinder (550) is operated, and when the loader (551) retracts, the opening guide device (500) also retracts together toward the floor material (400') installed on the left and right ends of the floor material (400) and the fixed rod (600) which is fixed to the bottom of the floor material (400').

[0072] In the drawing, during the process in which the opening guide device (500) moves downward toward the fixed rod (600), the opening plate (540) may be caught on the fixed rod (600) and rotated upward and tilted, thereby opening the operation.

[0073] With the opening of the above-mentioned opening (540), repair or replacement of a fire detector installed on any part of the bottom of the flooring material (400) can be conveniently performed.

[0074] Of course, when the above-mentioned opening member (540) is opened in the upward direction, the second rod (542) is rotated around the third rod (543) as an axis in such a way that it is removed from the receiving groove (511) of the opening guide member (510), so that the floor material (400) can be opened in the upward direction. At this time, the third rod (543) is not removed from the receiving groove (521) of the opening guide member (520) and acts as a reference axis for the rotation axis required for the upward opening of the above-mentioned opening member (540).

[0075] When the repair or replacement of the fire detector is completed and the reverse operation button is pressed again, the opening member (540) is completely detached from the fixed rod (600), and the second rod (542) is received and attached to the receiving groove (511) of the opening guide member (510) by the magnetic force acting in the receiving groove (511) of the opening guide member (510) and the weight of the flooring material (400), thereby returning the flooring material (400) to its original position and closing.

[0076] Meanwhile, when the forward operation button is pressed, the cylinder (550) is operated, and when the loader (551) moves forward, the opening guide device (500) also moves forward together toward the floor material (400') installed on the left and right ends of the floor material (400) and the fixed rod (600) which is fixed to the bottom of the floor material (400").

[0077] In the drawing, during the process in which the opening guide device (500) moves upward toward the fixed rod (600), the opening plate (540) may be caught on the fixed rod (600) and rotated downward and tilted, thereby opening.

[0078] With the opening of the above-mentioned opening (540), repair or replacement of a fire detector installed on any part of the bottom of the flooring material (400) can be conveniently performed.

[0079] Of course, when the above-mentioned opening member (540) is opened in the downward direction, the third rod (543) is rotated around the second rod (542) as an axis in such a way that it is removed from the receiving groove (521) of the opening guide member (520), so that the floor material (400) can be opened in the downward direction. At this time, the second rod (542) is not removed from the receiving groove (511) of the opening guide member (510) and acts as a reference axis for the rotation axis required for the downward opening of the above-mentioned opening member (540).

[0080] When the repair or replacement of the fire detector is completed and the forward operation button is pressed again, the opening member (540) is completely detached from the fixed rod (600), and the third rod (543) is received and attached to the receiving groove (521) of the opening guide member (520) by the magnetism acting in the receiving groove (521) of the opening guide member (520), thereby returning the floor material (400) to its original position and closing.
