Description

Raised floor structure

This invention relates to a raised floor structure, specifically a raised floor applied in the field of building construction. It can effectively absorb the relative displacement of buildings, avoid floor damage caused by earthquakes, and take into account both construction convenience and structural strength.

Raised floors refer to elevated floor structures formed by supporting frames, steel skeletons, and paved panels, commonly found in computer rooms and factories. A raised floor typically includes shelves, supporting frames, and flooring laid on top of them. It provides concealed space beneath the raised floor for equipment wiring, air conditioning systems, and piping, maintaining a clean and tidy indoor environment. To ensure continuity between different floors or buildings, modern raised floors often incorporate expansion joints at building junctions to absorb displacement during earthquakes.

However, when an elevated floor spans between two different buildings or floors, the traditional practice is to lock the expansion joint between the two buildings directly, preventing the expansion joint from functioning properly. In the event of an earthquake or relative displacement of the building structure, this can easily lead to stress concentration, cracking, or even damage to the floor, affecting its overall durability and safety.

In light of this, the creator has devoted considerable time to researching relevant knowledge, conducting research and development on related products, and undergoing numerous experiments and tests. Finally, a raised floor structure has been launched that can maintain continuity at the junction of buildings or floors and simultaneously provide a double expansion joint buffer effect, avoiding damage or cracking of the expansion joint connection due to earthquakes. This improves upon the aforementioned shortcomings and meets the needs of the public.

The main purpose of this invention is to maintain continuity at the junction of buildings or floor slabs while providing expansion joint cushioning. This avoids the shortcomings of conventional technologies where expansion joints are merely a formality and fail to effectively absorb relative building displacement, leading to stress concentration, cracking, or even damage to the floor. However, to achieve the aforementioned objectives and improve upon the deficiencies of conventional technologies, this invention provides a raised floor structure comprising: a floor slab of building A and a floor slab of building B, with a first expansion joint formed between building A and building B; and a plurality of H-beams, each H-beam being attached at both ends to the floor slabs of building A and building B. The top surface of the building, with each H-beam partially concealing the first expansion joint; a plurality of first fasteners, each first fastener securing each H-beam to the floor slab of Building A or Building B; a plurality of first supports, each first support being secured at one end to the top surface of the floor slab of Building A and the expansion joint. The top surface of the floor slab of Building B; a plurality of second supports, each second support fixed at one end to both ends of the top surface of each H-beam; a plurality of third supports, each third support fixed at one end to the top surface of each H-beam corresponding to the position covering the first expansion joint; a plurality of crossbeams, each crossbeam fixed to... Between any two first supports, or between any first support and any second support; a plurality of channel steels, each channel steel being fixedly assembled between a plurality of third supports on the same H-beam; a plurality of second fasteners, each second fastener locking each channel steel fixedly assembled on the plurality of third supports on the same H-beam to a third support away from the first fastener; a plurality of floorboards, each floorboard being assembled on the top surface of each channel steel, each first support, each second support, and each third support; furthermore, a second expansion joint is formed by further cutting a portion of the floorboards corresponding to the first expansion joint; a cover plate, the cover plate being secured by a plurality of third fasteners. The fixing components are fixed to the floor on one side of the second expansion joint, and the cover plate conceals the second expansion joint. 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 frame. Multiple floor panels are laid on the top surfaces of each channel steel, each first support frame, each second support frame, and each third support frame. The second expansion joint is formed by cutting the floor panels corresponding to the first expansion joint, achieving a double expansion and contraction buffering effect in conjunction with the first expansion joint. Furthermore, each third fixing component is locked to the same side as each second fixing component, but opposite to the side locked by each first fixing component.

Based on the technology defined above, its advantages lie in the load-bearing framework formed by H-beams, the first support frame, the second support frame, the third support frame, the crossbeams, and the channel steel, which enables the raised floor to possess excellent strength and stability, maintaining structural integrity even under large-area installation or long-term use. Furthermore, the first expansion joint formed between Building A and Building B, along with the corresponding second expansion joint cut into the floor, provides a dual expansion and contraction buffer mechanism. This prevents the building or floor slab from dispersing displacement stress during earthquakes, thus avoiding concentration of stress in a single location and preventing floor damage, thereby improving overall seismic resistance and safety. Furthermore, this invention utilizes a cover plate placed over the second expansion joint to effectively conceal the gap, maintaining a flat floor surface and preventing hazards caused by gaps when people walk or equipment moves, while also ensuring both comfort and safety in daily use. Moreover, each fastener is locked to a different component and arranged in a corresponding lateral configuration, avoiding the problems of uneven force distribution or loosening that occur in traditional locking methods. Its combination of structural strength, seismic resistance, and safety demonstrates the practicality and advancement of this invention, making it worthy of industry promotion.

To clearly illustrate the purpose and effects achieved by this invention, the following illustrations provide a detailed explanation of its features and effects through examples. Please refer to Figures 1 to 5. This invention provides a raised floor structure comprising: a floor slab 21 of building A and a floor slab 22 of building B. The floor slab 21 of building A and the floor slab 22 of building B... A first expansion joint 23 is formed between the plates 22; a plurality of H-beams 1, each H-beam 1 is respectively attached at both ends to the top surface of the floor slab 21 of Building A and the floor slab 22 of Building B; a plurality of first fasteners 24, each first fastener 24 respectively fixing each H-beam 1 to the floor slab 21 of Building A or the floor slab 22 of Building B, and each H-beam... The steel beams 1 partially cover the first expansion joint 23; a plurality of first supports 31, each first support 31 being fixed at one end to the top surface of the floor slab 21 of Building A and the top surface of the floor slab 22 of Building B; a plurality of second supports 32, each second support 32 being fixed at one end to both ends of the top surface of each H-beam 1; a plurality of third supports... 33, each third support 33 is fixed at one end to the top surface of each H-beam 1 corresponding to the position covering the first expansion joint 23, and two third supports 33 are fixed to the same H-beam 1; a plurality of crossbeams 5, each crossbeam 5 is fixed between any two first supports 31, or between any first support 31 and any second support 32; a plurality of slots Steel 4, each channel steel 4 is respectively fixed between a plurality of third supports 33 on the same H-beam 1; a plurality of second fasteners 41, each second fastener 41 respectively fixes each channel steel 4 to one of the third supports 33 on the same H-beam 1, locking the channel steel 4 to the third support 33 on one side, while the other side is not fixed by the second fastener 41. Steel 4 is locked to the third support 33; a plurality of floor panels 6 are respectively assembled on the top surface of each channel steel 4, each first support 31, each second support 32 and each third support 33; furthermore, a portion of the floor panel corresponding to the first expansion joint 23 is further cut to form a second expansion joint 61; a cover plate 7 is secured by a plurality of third fasteners 71. The cover plate 7 is fixed to the floor on one side of the second expansion joint 61, and the cover plate 7 conceals the second expansion joint 61; wherein, each H-beam 1, together with each first support frame 31, each second support frame 32, each third support frame 33, each crossbeam 5 and each channel steel 4, forms a load-bearing frame, and the plurality of floor panels 6 are respectively laid on each channel steel 4, each first support frame 31, each first support frame 32, each third support frame 33, each crossbeam 5 and each channel steel 4. The top surfaces of the two supports 32 and each of the third supports 33 are formed by cutting the floor portion corresponding to the first expansion joint 23 to create the second expansion joint 61. This, in conjunction with the first expansion joint 23, achieves a double expansion and contraction buffering effect. Furthermore, each of the third fasteners 71 and each of the second fasteners 41 is locked on the same side, but opposite to the side where each of the first fasteners 24 is locked. The drawings used herein are for illustrative purposes only and are not intended to limit the scope of the invention.

The raised floor structure created in this design consists of interconnected floor slabs 21 of Building A and 22 of Building B, along with multiple H-beams 1, and is supported by a first support frame 31, a second support frame 32, and a third support frame 33 to prevent structural breaks. The staggered arrangement of crossbeams 5 and channel steel 4 further enhances the overall load-bearing framework, providing sufficient support for the multiple floor slabs 6 laid upon them. This allows for pedestrian access and communication, as well as the transport of equipment and goods, between the floor slabs 21 of Building A and 22 of Building B. Furthermore, by further cutting a portion of the floor corresponding to the first expansion joint 23 to form a second expansion joint 61, and with the cover plate 7 for shielding, not only can a double expansion and contraction buffering effect be provided simultaneously to prevent displacement caused by earthquakes or load changes, but also to ensure the flatness and safety of the ground surface. That is, the structure of the raised floor of this invention can take into account strength, stability and expansion and contraction adjustment functions, providing better durability and reliability compared to conventional structures that can only absorb deformation through a single gap, as shown in Figures 1 to 5.

Furthermore, to ensure the raised floor structure maintains its stability over extended use, each of the first fasteners 24 uses expansion bolts, while each of the third fasteners 71 uses flathead bolts. The expansion bolts can penetrate deep into the floor slabs 21 of Building A or 22 of Building B to expand and tighten, preventing loosening due to vibration or expansion/contraction. The flathead bolts, on the other hand, keep the surface of the cover plate 7 flat, preventing protrusions that could obstruct movement or handling. However, users can still select other fastening components to assist in the installation of the raised floor, as shown in Figures 1 through 5, depending on their needs.

In addition, to allow the raised floor to also function as a piping system, a wiring area 8 is formed between the floor slab 21 of Building A, the floor slab 22 of Building B, and each floor 6. The wiring area 8 can accommodate power lines, communication cables, or air conditioning ducts, avoiding exposed wiring that would affect aesthetics and safety, and allowing for flexible adjustments during construction and maintenance. It is particularly suitable for factories or computer rooms requiring a large number of electromechanical facilities, as shown in Figures 1 and 3.

Continuing from the previous explanation, to facilitate users' inspection of the wiring condition or whether the wiring area 8 needs tidying up, the cover 7 can be made of a translucent material. This allows for observation of the interior of the wiring area 8 through the cover 7 without compromising structural shielding and protection, facilitating the inspection of dust accumulation or wiring distribution and improving overall maintenance efficiency (not shown in the figure).

Furthermore, to meet the needs of different applications, each floor 6 can be made of steel, aluminum, alloy sheet, or wood, or any combination thereof. Steel has high strength and durability, making it suitable for environments requiring high load-bearing capacity; aluminum and alloy sheet are lighter, making them easier to transport and assemble; wood provides better sound absorption and comfort. Users can configure the most suitable floor 6 material for the raised floor according to their actual needs (not shown in the figure).
