Abstract
Description
Technical Field
[0001] The invention relates to a foot frame for an elevated floor. Background Art
[0002] Currently, the floors of clean rooms in large semiconductor or panel factories are composed of multiple elevated floors. There is a suspended space of a certain distance between the elevated floors and the floor surface. In addition to being used for arranging pipelines and construction workers, this suspended space can also be used to install exhaust equipment.
[0003] In addition, in order to ensure the safety and convenience of personnel movement and goods transportation in the factory, the tripods of all elevated floors will be adjusted to make the height of the adjusted elevated floors consistent to maintain the flatness of the overall floor surface. In order to cope with the floor height required by different factories, the elevated floors will be equipped with tripods of different heights.
[0004] The existing tripod consists of a support tube, a bottom plate, a support top plate and a screw with adjustable height. The bottom plate is welded to the bottom end of the support tube, and one end of the screw is welded to the bottom of the support top plate. The support top plate is used to support the elevated floor. The other end of the screw is screwed into the pipe cover of the support tube. It can be seen that by adjusting the height of the screw, the required height of the support top plate and the elevated floor it supports can be adjusted. In other words, if you want the support top plate to have a larger adjustable height range, or if you need a larger space under the elevated floor, you need to use a longer screw and support tube body. However, the pipe cover is not fixed on the support tube, which will cause the support top plate to shake easily and easily cause the height of the support top plate to shift.
[0005] In addition, since the other end of the screw is rotated and moved in the support tube, the support tube needs to have a certain height distance to provide a rotation stroke of the screw, which will cause the height of the entire tripod to be unable to be reduced and the structure is complicated. Summary of the invention
[0006] The invention aims to provide a tripod for a raised floor, which is used for the raised floor of an office or a computer room, and has a short tripod and a simple structure.

DETAILED DESCRIPTION
[0032] The following examples are listed and described in detail with the accompanying drawings, but the examples provided are not intended to limit the scope of the present invention. In addition, the drawings are for illustration purposes only and are not drawn to their original size. For ease of understanding, the same elements will be described with the same symbols in the following description.
[0033] The terms “including”, “comprising”, “having”, etc. mentioned in the present invention are all open terms, that is, meaning “including but not limited to”.
[0034] In the description of each embodiment, when the terms “first,” “second,” “third,” “fourth,” etc. are used to describe an element, it is only used to distinguish these elements from each other and does not limit the order or importance of these elements.
[0035] In the description of each embodiment, the so-called "coupling" or "connection" may refer to two or more elements making direct physical or electrical contact with each other, or making indirect physical or electrical contact with each other, and "coupling" or "connection" may also refer to two or more elements operating or moving with each other.
[0036] Figure 1 It is a schematic diagram of the tripod of the elevated floor of the present invention. Figure 2 It is a schematic exploded view of the tripod of the elevated floor of the present invention. Figure 3 Schematic diagram of the raised floor stand and the raised floor of the present invention. Figures 1 to 3The raised floor stand 100 of the present invention is an ultra-low stand. The height of the raised floor stand 100 is below 35 cm and the load bearing capacity is above 350 kg. If a larger load is required, the diameter of the rod body 112 needs to be increased. Therefore, the present invention can be used to adjust the height of the raised floor 50. The raised floor 50 is used in an office or computer room or a semiconductor plant with a lighter load, which is convenient for pulling network cables and makes the ground less cluttered. The raised floor stand 100 includes a rod device 110, a supporting top plate 120, a nut element 130, a stop element 140, at least one gasket element 150, and a bottom plate 160.
[0037] The tooth bar device 110 includes a tooth bar body 112, a first end 114 and a second end 116. The tooth bar body 112 is a screw rod with a fixed length. The first end 114 and the second end 116 are opposite sides of the tooth bar body 112. The first end 114 of the tooth bar body 112 passes through the supporting top plate 120, and the second end 116 of the tooth bar body 112 is fixed on the bottom plate 160. The bottom plate 160 is fixed on the floor, for example, so that the tooth bar body 112 is fixed by the bottom plate 160, and the supporting top plate 120 can move on the tooth bar body 112. There is an adjustment distance D between the support top plate 120 and the bottom plate 160. Since the support top plate 120 is not fixed by the rod body 112, the support top plate 120 can move on the rod body 112 to adjust the length of the adjustment distance D, and the top surface 124 of the support top plate 120 is used to be fixed to the elevated floor 50, so that the horizontal height of the elevated floor 50 can be adjusted by moving the support top plate 120.
[0038] In addition, since the rod body 112 in the elevated floor stand 100 itself does not need to move but is an element of fixed length, the present invention utilizes the support top plate 120 to move on the rod body 112. Compared with the movement of the rod body 112 on a certain element, additional rotating elements and fixing elements are required, which increases the setting height of the stand. Therefore, the setting method of the present invention can significantly reduce the height of the elevated floor stand 100.
[0039] The support top plate 120 includes a support plate body 122, a tooth rod hole 122A, a top surface 124, a bottom surface 126, a groove 127, a floor fixing hole 129, and at least one cross beam hole 128, wherein the top surface 124 and the bottom surface 126 are two opposite sides of the support plate body 122. The tooth rod hole 122A is penetrated through the support plate body 122, and the tooth rod hole 122A is located at the center of the support plate body 122. At least one (such as Figure 1 There are four cross beam holes 128 respectively penetrated through the support plate body 122, and the positions of the cross beam holes 128 are different from the positions of the tooth rod holes 122A. Figure 1As shown, the positions of the four crossbeam holes 128 are respectively located around the tooth rod hole 122A, and the center line of two adjacent crossbeam holes 128 is perpendicular to the center of the tooth rod hole 122A, so that the elevated floor 50 is fixed on the crossbeam and the support plate body 122 perpendicular to each other. Floor fixing holes 129 are penetrated through the support plate body 122, and the positions of these floor fixing holes 129 are respectively different from the positions of the crossbeam holes 128 and the positions of the tooth rod hole 122A, and the groove 127 is recessed in the support plate body 122, and the groove 127 is located between the adjacent floor fixing holes 129 and the crossbeam holes 128.
[0040] The first end 114 of the rod body 112 is inserted into the rod hole 112A, so that the first end 114 of the rod body 112 protrudes above the top surface 124 of the support top plate 120, and the hole diameter of the rod hole 112A is larger than the outer diameter of the rod body 112, so that the support top plate 120 can move relative to the rod body 112, and the top surface 124 of the support top plate 120 is used to be fixed to the elevated floor 50.
[0041] In one embodiment, the spacer element 150 is inserted into the corresponding groove 127, so that when the elevated floor 50 is fixed on the floor fixing hole 129, the earthquake resistance of the elevated floor 50 can be increased and the levelness of the elevated floor 50 can be adjusted. A beam fixing hole 125 can also be added to the front end of the floor fixing hole 129, i.e., the front end of the sharp octagonal shape, as required, to connect and fix the beam to the supporting top plate 120, so as to improve the earthquake resistance of the elevated floor 50 and the stability of the elevated floor stand 100.
[0042] The nut element 130 is movably screwed on the rod body 112, and one side of the nut element 130 is welded and fixed to the bottom surface 126 of the support top plate 120. Under this setting, the nut element 130 is rotated to adjust the position of the support top plate 120 relative to the rod body 112, so that the support top plate 120 is linked to the elevated floor 50, thereby adjusting the horizontal height of the elevated floor 50.
[0043] In one embodiment, the area of the supporting top plate 120 is larger than the area of the nut element 130 , so that the volume of the nut element 130 can be minimized and the overall installation space can be reduced.
[0044] In one embodiment, the nut element 130 is located between the support top plate 120 and the stop element 140. The function of the stop element 140 is to fix the position of the nut element 130 or to prevent the nut element 130 from rotating. The stop element 140 includes a connecting member 142 and a wrench member 144. The connecting member 142 is connected to the wrench member 144. The connecting member 142 and the wrench member 144 are respectively inserted into the tooth bar body 112. The wrench member 144 protrudes from the outside of the nut element 130 for the user to rotate. The stop element 140 can be, for example, stamped through a plate and cut into a desired finished product shape and size, such as the wrench member 144 and the connecting member 142, and is integrally formed by stamping.
[0045] Figure 4 Schematic diagram of the elevated floor used to support the elevated floor of the present invention. Figure 4 , which discloses that the elevated floor stand 200 is provided on the ground 201 and the elevated floor 202, wherein the elevated floor stand 200 can be used for the aforementioned Figures 1 to 3 The raised floor stand 100, the aforementioned Figure 3 The elevated floor 50 may include an elevated floor 202. The elevated floor 202 includes a panel 2021 and a plurality of side ribs 2022, wherein the side ribs 2022 are disposed below the panel 2021, and a portion of the outer edge of the panel 2021 protrudes from the side ribs 2022 to form a floor flange 2023. A crossbeam 33 may span between the legs 200 of adjacent elevated floors, and the two ends of the crossbeam 33 are respectively fixed to the crossbeam holes (such as the holes in the support plate body 122) of the support plate body 122. Figure 1 The elevated floor 202 can be a steel or aluminum floor, and its four corners can be fixed to the floor fixing holes (such as the floor fixing holes 122 of the support plate body 122 of the four elevated floor legs 200) using a bolt 2024 respectively. Figure 1 The floor fixing holes 129 are provided, and the floor flanges 2023 of the elevated floor 202 are supported on the cross beam 33, and the adjacent floor flanges 2023 are supported on the same cross beam 33. It can be seen that the present invention can support the four corners of an elevated floor with four legs, in other words, one leg 200 of the elevated floor can support one corner of four elevated floors 202 respectively.
[0046] In summary, since the rod body in the elevated floor stand does not need to be moved but is an element of fixed length, the present invention utilizes a nut element to rotate to adjust the position of the support top plate relative to the rod body, so that the support top plate moves on the rod body. Compared with the rod body moving on a certain element, additional rotating elements and fixing elements are required, which increases the setting height of the elevated floor stand and increases the complexity of the elevated floor stand structure. Therefore, the setting method of the present invention can greatly reduce the height of the elevated floor stand and can be used in offices or computer rooms or semiconductor factories with lighter loads. It has a simple structure, is conducive to pulling network cables, and the floor is less cluttered.
[0047] Although the present invention has been disclosed by the embodiments as above, it is not intended to limit the present invention. Any ordinary technician with common knowledge in the relevant technical field should be able to make some changes and modifications without departing from the spirit and scope of the present invention, but all belong to the protection scope of the present invention.
