Description

Technical Field

[0001] The invention relates to a floor structure, in particular to a bearing structure and an elevated floor with a footrest. Background Art

[0002] Currently, semiconductor factories are equipped with elevated floors with multiple micro-perforations to purify the air quality in the environment and ensure the specifications of the clean room.

[0003] Currently, elevated floors are manufactured by die casting. In the die casting process, a desired product is often manufactured by a mold, and before the die casting operation, a release layer is first applied to the mold to facilitate subsequent demoulding operations.

[0004] However, the existing elevated floor is fixed to four I-shaped steel beams at its four corners with screws. Therefore, when the elevated floor is erected, the tolerances of the locking screws at each corner are inconsistent, and it is often impossible to lay it evenly on the I-shaped steel beam, causing the elevated floor to easily warp up and make the ground uneven.

[0005] Furthermore, although the tightness of the screws can be adjusted, the stress distribution of the elevated floor is constantly changed, which can easily damage the internal structure of the elevated floor and cause the elevated floor to rupture.

[0006] In addition, the elevated floor needs to be installed by screws, which not only increases the process and is time-consuming, but also increases the installation cost.

[0007] Therefore, how to overcome the above-mentioned problems of the prior art has become a difficult problem that needs to be overcome urgently in the industry. Summary of the invention

[0008] The object of the present invention is to provide a load-bearing structure and an elevated floor thereof to solve at least one of the above problems.

[0009] In view of the various defects of the above-mentioned prior art, the present invention provides an elevated floor, which is erected on an I-shaped steel beam, and comprises: a top plate having a ground side and a honeycomb side opposite to each other; and a foot base, which is arranged on the honeycomb side of the top plate, wherein the foot base has a recessed portion for engaging with a convex portion of a metal gasket provided on the I-shaped steel beam, so that the foot base is clamped on the metal gasket.

[0010] In the above-mentioned elevated floor, the metal gasket has eight protrusions. For example, the eight protrusions form a structure of four groups of protrusions, and the two protrusions in each group are perpendicular to each other to be clamped on the concave part of the footrest. Alternatively, the eight protrusions are respectively clamped on the footrests of four elevated floors.

[0011] In the above-mentioned elevated floor, the long side of the convex part is perpendicular to the concave part. In addition, the metal gasket is adhered to the I-shaped steel beam.

[0012] In the aforementioned elevated floor, the bottom of the footrest is L-shaped.

[0013] In the aforementioned elevated floor, a plurality of through holes are formed on the top plate to connect the ground side and the honeycomb side.

[0014] In the aforementioned elevated floor, the width of the concave portion is greater than the width of the convex portion.

[0015] The present invention also provides a bearing structure, comprising: a plurality of tripods, each of which has a square support seat at the top; a plurality of first steel beams, which are mounted on the plurality of tripods in a screw-locking manner to form an outer frame, and one end of four of the plurality of first steel beams is located on the support seat at the top of the same tripod; at least one second steel beam, which is mounted in the outer frame at a preset interval, and the two ends of the second steel beam are respectively connected and fixed to the first steel beam to form a single-layer steel beam structure, wherein the first steel beam and the second steel beam are fixed by a flat connecting element, and the flat connecting element is connected by a first The invention is composed of a steel plate and a second steel plate, and the first steel plate and the second steel plate are perpendicular to each other, wherein the vertical surface of the first steel plate is fixed to the vertical surface of the first steel beam by welding, and is fixed to the second steel beam by screw locking, and the horizontal surface of the second steel plate is fixed to the bottom surface of the first steel beam by welding, and is fixed to the second steel beam by screw locking; and a plurality of metal gaskets having a plurality of protrusions and arranged on the first steel beam and the second steel beam, wherein the plurality of metal gaskets are fixed to the first steel beam and the second steel beam at intervals of a preset distance.

[0016] The aforementioned bearing structure also includes a plurality of elevated floors, each of the elevated floors has a footrest with a recessed portion, the recessed portion engages with the convex portion of the metal gasket, so that the plurality of elevated floors are embedded in the metal gaskets on the first steel beam and the second steel beam.

[0017] In the aforementioned bearing structure, the metal gasket has eight protrusions, and the eight protrusions form a structure of four groups of protrusions. The two protrusions in each group are arranged perpendicularly to each other so as to be clamped on the concave portion of the foot.

[0018] As can be seen from the above, in the bearing structure and the elevated floor thereof of the present invention, a recess is formed on the foot, so that when the elevated floor is erected, the foot can be fixed to the I-shaped steel beam in an embedded manner by simply engaging the recess with the protrusion of the metal gasket. Therefore, compared with the tolerance influence of existing screws, the elevated floor of the present invention can be effectively and evenly laid on the I-shaped steel beam because there is no tolerance problem of existing screws, thereby avoiding the problem of the elevated floor warping up and making the ground uneven.

[0019] Furthermore, if the heights of the four corners of the elevated floor are inconsistent, it is only necessary to adjust the height of the footrest (or I-shaped steel beam) without applying external force to the elevated floor. Therefore, the stress distribution of the elevated floor will not be changed, and the internal structure of the elevated floor will not be damaged. Therefore, compared with the prior art, the elevated floor of the present invention can avoid the problem of cracking.

[0020] In addition, the elevated floor of the present invention does not need to be installed on the I-shaped steel beam by screws, thus not only simplifying the process and saving time, but also reducing installation costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Figure 1A , Figure 1B and Figure 1C FIG. 1 is a schematic diagram of a first embodiment of an elevated floor 1 of the present invention.

[0065] The elevated floor 1 is a blind plate, comprising a top plate 10, a rib structure 1a disposed on the top plate 10, and side plates 1b.

[0066] The top plate 10 has a ground side 10a and a honeycomb side 10b opposite to each other. The ground side 10a is a flat surface, and the honeycomb side 10b is provided with the rib structure 1a and the side plate 1b in the longitudinal direction and the transverse direction, respectively.

[0067] In this embodiment, the top plate 10 is substantially rectangular, such as a square plate, and a wing plate 11 protruding from the rib structure 1a is formed around the top plate 10, and footrests 12 are formed on the four corners of the side plate 1b of the honeycomb side 10b of the top plate 10, and the bottom of the footrest 12 is L-shaped for fixing to an I-shaped steel beam 3 (such as Figure 4A and Figure 4B shown).

[0068] Furthermore, the foot 12 has a plurality of (eg, two) recesses 120 to engage with the convex portion 30 (eg, Figure 3A and Figure 3B As shown), the I-shaped steel beam 3 includes a first steel beam 31 and a second steel beam 32, and the width of the recess 120 is greater than the width of the protrusion 30, and the long sides of the plurality of protrusions 30 are respectively perpendicular to the plurality of recesses 120, so that the elevated floor 1 is easy to construct and lay on the I-shaped steel beam 3.

[0069] like Figure 4A and Figure 4BAs shown, the present invention also provides a bearing structure 4 for bearing, for example, a cabinet device (not shown), which includes the supporting device 4a and a plurality of the elevated floors 1, wherein the supporting device 4a includes: a plurality of legs 41, a plurality of diagonal braces 42, a plurality of first steel beams 31, a plurality of second steel beams 32, a plurality of metal gaskets 3a and a plurality of flat connecting elements 33, so that the elevated floor 1 is arranged on the plurality of first steel beams 31 and the plurality of second steel beams 32.

[0070] Furthermore, a square support seat 411 is disposed at the top of each tripod 41 . The square support seat 411 has eight locking holes 412 . The eight locking holes 412 are symmetrically distributed at the corners of the square support seat 411 for fixing the first steel beam 31 .

[0071] The tripod 41 is disposed below the first steel beam 31 and the second steel beam 32 to provide a supporting function, wherein four first steel beams 31 are mounted on a plurality of square support seats 411 at the top of the tripods 41 to form an outer frame 34, and two adjacent first steel beams 31 are fixed to the square support seat 411 at the top of the tripod 41 via an L-shaped connecting element 35, and the L-shaped connecting element 35 is respectively fixed to the two first steel beams 31 by screw locking, so as to strengthen the connection between the two adjacent first steel beams 31, so as to enhance the overall stability and load-bearing capacity of the supporting device 4a; in addition, the square support seat 411 at the top of the single tripod 41 can be used to support one end of the four first steel beams 31.

[0072] The second steel beam 32 is arranged in the outer frame 34 surrounded by the plurality of first steel beams 31 at a preset interval, and the two ends of the second steel beam 32 are respectively connected and fixed to the first steel beam 31. The preset interval is determined according to the elevated floor 1 to be laid. Generally speaking, the distance of the preset interval is approximately equal to the side length of the elevated floor 1 to be laid. Further, the first steel beam 31 and the second steel beam 32 are fixed by a flat connecting element 33, and the flat connecting element 33 includes a first steel plate 331 and a second steel plate 332, and the first steel plate 331 and the second steel plate 332 are perpendicular to each other. The vertical surface of the first steel plate 331 is fixed to the vertical surface of the first steel beam 31 by welding, and then fixed to the second steel beam 32 by screw locking. The horizontal surface of the second steel plate 332 is fixed to the bottom surface of the first steel beam 31 by welding, and fixed to the second steel beam 32 by screw locking. The flat connecting element 33 is used to strengthen the connection between the first steel beam 31 and the second steel beam 32 to enhance the overall stability and load-bearing capacity of the supporting device 4 a.

[0073] Metal gaskets 3 a are fixed on the first steel beam 31 and the second steel beam 32 , and the metal gaskets 3 a are used to fix the elevated floor 1 .

[0074] The foot frame 41 is substantially vertically erected on the floor to support the lower side of the corner A of the elevated floor 1 .

[0075] The diagonal brace 42 is an L-shaped angle steel body, one end of which is arranged at the end of the bottom section of the tripod 41 and is correspondingly located below the corner A of the elevated floor 1, and the other end is arranged on the I-shaped steel beam 3 (such as the first steel beam 31), so that the diagonal brace 42 is inclined below the I-shaped steel beam 3.

[0076] A metal gasket 3a having the protrusion 30 is attached to the I-shaped steel beam 3, such as an aluminum gasket (such as Figure 3A and Figure 3B As shown in FIG. 1 , the metal gasket 3a is fixed to the first steel beam 31 and the second steel beam 32 at a predetermined distance, the predetermined distance being the width of the square elevated floor 1 used, and the metal gasket 3a can be used to erect four elevated floors 1 (for example, located at the corners A of the four elevated floors 1). It should be understood that the gasket 3a can also be fixed to the I-shaped steel beam 3 by welding or by using screws and nuts in a locking manner.

[0077] In addition, if Figure 3A As shown, the arrangement of the protrusions 30 corresponds to the shape of the foot 12, so the metal gasket 3a is configured with two protrusions 30 for a single foot 12, and a single metal gasket 3a can be used to erect four elevated floors 1, so the metal gasket 3a can be configured with a total of eight protrusions 30, and the eight protrusions 30 are grouped in two to form a structure of four groups of protrusions 30, and the protrusions 30 of each group are arranged perpendicular to each other to be clamped on the recessed portion 120 of the foot 12, so that the eight protrusions 30 are clamped on the four elevated floors 1.

[0078] The rib structure 1a has a plurality of ribs 14 formed from the edge of the top plate 10 toward the middle.

[0079] In this embodiment, a plurality of grooves S are formed between the longitudinal and transverse ribs 14, wherein: Figure 1B Only the edge transverse rib structure 1a is shown, and the edge transverse rib structure 1a is the same as the edge longitudinal rib structure 1a, so the cross section of the edge transverse rib structure 1a is omitted.

[0080] Furthermore, a plurality of grooves S are arranged in an array to form a honeycomb structure having a plurality of ejector pin positions 13 (approximately at the corners of a square area formed by four grooves S) on the honeycomb side 10b.

[0081] Therefore, the elevated floor 1 of the present invention mainly forms recesses 120 on the feet 12 at the four corners A of the honeycomb side 10b of the top plate 10, so that when the elevated floor 1 is erected on the supporting device 4a, it is only necessary to engage the recesses 120 with the protrusions 30, so that the feet 12 at the four corners A can be respectively fixed to the four metal gaskets 3a in an embedded manner. Therefore, compared with the existing method of fixing the elevated floor with screws, the elevated floor 1 of the present invention does not have the problem of fixing the elevated floor 1 with screws, and can effectively lay the elevated floor 1 flat on the I-shaped steel beam 3, and can avoid the problem of the elevated floor 1 warping up and causing the ground to be uneven and unsightly.

[0082] Furthermore, if the heights of the four corners A of the elevated floor 1 are inconsistent, it is only necessary to adjust the height of the footrest 41 (or the I-shaped steel beam 3) without applying external force to the elevated floor 1, thereby not changing the stress distribution of the elevated floor 1, and not damaging the internal structure of the elevated floor 1. Therefore, compared with the prior art, the elevated floor 1 of the present invention can avoid the problem of cracking.

[0083] In addition, the elevated floor 1 of the present invention does not need to be installed on the I-shaped steel beam 3 by screws, which not only simplifies the process and saves time, but also reduces the installation cost.

[0084] Figure 2A , Figure 2B and Figure 2C Schematic diagram of a second embodiment of the elevated floor 2 of the present invention. The difference between this embodiment and the above embodiment is that the elevated floor 2 is a honeycomb board having a plurality of through holes 20, so the same points will not be described in detail below.

[0085] like FIG. 2A to FIG. 2C As shown, based on the first embodiment, the elevated floor 2 is formed with a plurality of through holes 20 on the top plate 10 that communicate with the ground side 10 a and the honeycomb side 10 b .

[0086] In this embodiment, the positions of the plurality of through holes 20 correspond to the configuration of the plurality of grooves S. For example, nine through holes 20 are formed on each groove S, and the nine through holes 20 are arranged in an array, so that each groove S is provided with three rows of through holes 20, and each row has three through holes 20.

[0087] Furthermore, the conductive tiles 40 can be pasted on the ground side 10a of the top plate 10, and a rectangular ring-shaped insulating protection strip 21 is embedded on the edge of the wing plate 11. For example, the color of the insulating protection strip 21 is black.

[0088] Similarly, the elevated floor 2 of the present invention is mainly formed with recesses 220 on the feet 22 at the four corners C of the honeycomb side 10b of the top plate 10, so that when the elevated floor 2 is erected on the supporting device 4a, Figure 4AAs shown, it is only necessary to connect the concave portion 220 to a metal gasket 3a having the convex portion 30, such as an aluminum gasket (such as Figure 3A and Figure 3B As shown in the figure, the feet 22 at the four corners C of the elevated floor 2 can be fixedly connected to the four metal gaskets 3a provided on the first steel beam 31 and the second steel beam 32 in an embedded manner. Therefore, compared with the existing elevated floor fixed with screws, the elevated floor 2 of the present invention does not have the problem of fixing the elevated floor 1 with screws, and can effectively lay the elevated floor 1 flat on the I-shaped steel beam 3 to avoid the problem of the elevated floor 2 warping up and causing the ground to be uneven and unsightly.

[0089] Furthermore, if the heights of the four corners C of the elevated floor 2 are inconsistent, it is only necessary to adjust the height of the footrest 41 (or the I-shaped steel beam 3) without applying external force to the elevated floor 2, thereby not changing the stress distribution of the elevated floor 2 and not damaging the internal structure of the elevated floor 2. Therefore, compared with the prior art, the elevated floor 2 of the present invention can avoid the problem of cracking.

[0090] In addition, the elevated floor 2 of the present invention does not need to be installed on the I-shaped steel beam 3 by screws, which not only simplifies the process and saves time, but also reduces the installation cost.

[0091] In summary, the bearing structure 4 and the elevated floors 1, 2 of the present invention are mainly designed with the recesses 120, 220 so that they can be mounted on the metal gaskets 3a on the first steel beam 31 and the second steel beam 32 in an embedded manner, thereby eliminating the need for existing screws, thereby facilitating smooth laying on the I-shaped steel beam 3. Therefore, the elevated floors 1, 2 of the present invention can avoid problems such as warping and cracking.

[0092] On the other hand, the elevated floors 1, 2 of the present invention do not need to be mounted on the I-shaped steel beam 3 by screws, thereby not only simplifying the process and saving time, but also reducing installation costs.

[0093] The above embodiments are used to illustrate the principles and effects of the present invention, but are not used to limit the present invention. Those skilled in the art may modify the above embodiments without violating the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be as listed in the claims.
