Description

Double-layer bearing structure and raised floor thereof

Technical Field

The utility model relates to a floor structure, in particular to a double-layer bearing structure in a double-layer steel beam form and an overhead floor with a foot seat.

Background

In the conventional semiconductor factory building, a raised floor having a plurality of micro-holes is disposed to clean the air quality of the environment and ensure the specification of the clean room.

At present, raised floors are manufactured in a die casting mode. In the die casting process, a die is used to manufacture a desired product, and before the die casting process is performed, a release layer is coated in the die to facilitate the subsequent demolding process.

However, the existing raised floor is fixedly connected to the four I-shaped steel beams by screws at four corners thereof, so that when the raised floor is erected, the tolerance of locking screws at each corner is inconsistent, and therefore the raised floor cannot be laid on the I-shaped steel beams smoothly, and the raised floor is easy to warp upwards to cause uneven ground.

In addition, although the tightness of the screw can be adjusted, the stress distribution of the raised floor is continuously changed, so that the internal structure of the raised floor is easily damaged, and the raised floor is broken.

In addition, the elevated floor is required to be erected by screws, which not only increases the process time, but also increases the installation cost.

Therefore, how to overcome the above problems in the prior art has become a major challenge in the industry.

Disclosure of Invention

The present utility model is directed to a dual-layer bearing structure and raised floor thereof, which solves at least one of the above problems.

In view of the above-mentioned drawbacks of the prior art, the present utility model provides an elevated floor comprising: a ceiling having opposite ground and honeycomb sides; and a foot stand provided on the honeycomb side of the antenna board and having a concave portion; the raised floor is erected on an I-shaped steel beam with a metal gasket, and the metal gasket is provided with a convex part for clamping the concave part of the foot seat to the convex part of the metal gasket.

In the raised floor, the metal pad has eight protrusions. For example, the eight protruding portions form a four-group protruding portion structure, and two protruding portions of each group are perpendicular to each other so as to be clamped on the concave portion of the foot seat. Or the eight convex parts are respectively clamped on the foot seats of the four raised floors.

In the raised floor, the long side of the convex portion is perpendicular to the concave portion.

In the above raised floor, the metal pad is adhered to the I-beam.

In the raised floor, the bottom of the footstand is L-shaped.

In the raised floor, a plurality of through holes are formed in the ceiling plate to communicate the floor side and the honeycomb side.

In the raised floor, the width of the concave portion is larger than the width of the convex portion.

The present utility model also provides a dual-layer bearing structure, comprising: a plurality of foot rests; the plurality of H-shaped steel beams are arranged on the plurality of foot frames and are arranged and erected on the plurality of foot frames along a first direction by taking a first preset distance as an interval; the I-shaped steel beams are arranged on the H-shaped steel beams and are arranged and erected on the H-shaped steel beams along a second direction at intervals of a second preset distance to form a double-layer steel beam form; and the metal gaskets are provided with a plurality of convex parts, are arranged on the I-shaped steel beam and are fixed on the I-shaped steel beam at intervals of a third preset distance.

In the foregoing dual-layer bearing structure, the raised floor further includes a plurality of raised floors with pedestals, the pedestals have recesses, and the recesses are engaged with the protrusions of the metal pads, so that the raised floors are embedded and clamped on the metal pads of the I-shaped steel beams.

In the foregoing double-deck bearing structure, the connecting plate is fixedly connected to the I-shaped steel beam and the H-shaped steel beam, so that two adjacent I-shaped steel beams are fixedly connected to the H-shaped steel beam.

In the above-mentioned dual-layer bearing structure, the metal pad has eight protrusions, and the eight protrusions form a structure of four groups of protrusions, and two protrusions of each group are vertically arranged with each other to be clamped on the concave portion of the foot stand.

Therefore, in the double-layer bearing structure and the raised floor thereof, the concave part is mainly formed on the foot seat, so that when the raised floor is erected, the foot seat can be fixedly connected with the I-shaped steel beam in a clamping manner only by jointing the concave part with the convex part of the metal gasket, and compared with the tolerance influence of the existing screw, the raised floor can be effectively and flatly laid on the I-shaped steel beam due to the fact that the tolerance problem of the existing screw is avoided, and the problem of uneven ground caused by upwarp of the raised floor is avoided.

In addition, if the heights of the four corners of the raised floor are inconsistent, only the height of the foot rest (or the I-shaped steel beam) is required to be adjusted, and no external force is required to be applied to the raised floor, so that the stress distribution of the raised floor is not changed, and the internal structure of the raised floor is not damaged.

In addition, the overhead floor of the utility model does not need to be erected on the I-shaped steel beam through screws, so that the working procedure can be simplified, the time is saved, and the installation cost is reduced.
