A method for constructing an elevated floor and the structure thereof

Abstract

This invention discloses a method and structure for erecting raised floors. The erection method includes steps for assembling H-beams, supporting frames, crossbeams, channel steel, floor panels, floor cutting, and cover plate assembly. The structural part consists of H-beams forming a load-bearing skeleton in conjunction with first, second, and third supporting frames, crossbeams, and channel steel. Multiple floor panels are laid on the top surfaces of each channel steel and crossbeam. By cutting the floor panels corresponding to the first expansion joint to form the second expansion joint, a double expansion and buffering effect can be achieved in conjunction with the first expansion joint.

Claims

1. An elevated floor structure, comprising: a floor slab of building A and a floor slab of building B, wherein the distance between the floor slabs of building A and building B forms a first expansion joint; a plurality of H-beams, each H-beam being attached to the top surface of the floor slabs of building A and building B at both ends; a plurality of first fasteners, each first fastener fixing each H-beam to the floor slab of building A or the floor slab of building B; a plurality of first support frames, each first support frame being fixed to the top surface of the floor slabs of building A and building B at one end; a plurality of second support frames, each second support frame being fixed to both ends of the top surface of each H-beam at one end; and a plurality of third support frames, each third support frame being fixed to the top surface of each H-beam at one end. The top surface corresponds to the position that conceals the first expansion joint; a plurality of crossbeams, each crossbeam being fixed between any two first support frames, or between any first support frame and any second support frame; a plurality of channel steels, each channel steel being fixed between a plurality of third support frames on the same H-beam; a plurality of second fasteners, which fix each channel steel to one of the third support frames on the same H-beam; a plurality of floor panels, each floor panel being assembled on the top surface of each channel steel, each first support frame, each second support frame, and each third support frame; furthermore, a second expansion joint is formed by further cutting a portion of the floor panels corresponding to the first expansion joint; a cover plate, which is fixed to the floor panel on one side of the second expansion joint by a plurality of third fasteners, and the cover plate conceals the second expansion joint; wherein... Each H-beam, together with each first support frame, each second support frame, each third support frame, each crossbeam, and each channel steel, forms a load-bearing skeleton. Multiple floor systems are laid on the top surfaces of each channel steel, each first support frame, each second support frame, and each third support frame. By cutting the part of the floor corresponding to the first expansion joint to form the second expansion joint, the double expansion and buffering effect can be achieved in conjunction with the first expansion joint.

2. The raised floor structure as described in claim 1, wherein, Each of the first fasteners is an expansion bolt, while each of the third fasteners is a flathead bolt.

3. The raised floor structure as described in claim 1, wherein, The cover is made of a light-transmitting material.

4. The raised floor structure as described in claim 1, wherein, A wiring area is formed between the floor slabs of Building A, the floor slabs of Building B, and the various floorboards.

5. The raised floor structure as described in claim 1, wherein, The flooring material can be steel, aluminum, alloy sheet, wood, or any combination thereof.

6. The raised floor structure as described in claim 1, wherein, On the other side, the channel steel is not locked to the third support frame by the second fastener.

7. The raised floor structure as described in claim 1, wherein, Two third support frames are fixed to the same H-beam.

8. The raised floor structure as described in claim 1, wherein, The plurality of first fasteners respectively fix one end of each H-beam to the floor slab of Building A or the floor slab of Building B, while the other side of each H-beam is not fixed.
