Description

Technical Field

[0001] The utility model belongs to the technical field of truss floor decking, and more specifically, relates to a detachable FRP bar reinforced truss floor decking structure. Background Art

[0002] Truss floor decks, also known as reinforced truss floor decks, are constructed by regularly arranging multiple steel bars and connecting them through resistance spot welding to form a reinforced truss. The truss is then joined to the base plate through resistance spot welding to form a single, integrated load-bearing plate. Reinforced truss floor decks offer a range of technical advantages, including rapid construction, easily controlled quality, and flexible structural layout. Their application in building construction continues to expand, playing a significant role in improving the quality, schedule, and cost-effectiveness of structural engineering construction.

[0003] However, truss floor decks connected using resistance spot welding are difficult to recycle after construction, which can easily lead to waste of construction materials. Furthermore, corrosion of the steel bars can easily lead to premature structural failure, especially in offshore or marine environments, salt crystallization environments, and chemical corrosion environments, which can accelerate the corrosion of the steel bars and significantly reduce the bearing capacity of the truss floor deck. Furthermore, in some specialized engineering fields, the building structure must have low or even no magnetism, which makes ordinary steel bars no longer meet the engineering requirements. Therefore, how to improve the existing truss floor deck structure to make the base plate easier to disassemble and recycle is a question worth considering for those skilled in the art. Utility Model Content

[0041] Reference Figure 1-4 , an embodiment of the utility model provides a detachable FRP bar reinforced truss floor deck structure, comprising a truss, a connection assembly and a bottom plate 1;

[0042] The truss includes a triangular top rib 2, a first side rib 3, a second side rib 4, and a first support rib 5 and a second support rib 6, both of which are wavy. The first support rib 5 and the second support rib 6 are connected to both sides of the top rib 2 at their wave crests, and the troughs of the first and second support ribs have extensions 7 extending outward from the inner sides of the first side rib 3 and the second side rib 4, respectively.

[0043] The connecting assembly includes a connecting block 8, a hanging rod 9, a connecting rod 10 and a fastener 11. The extension portion 7 is arranged on the connecting block 8 and is fixed by the hanging rod 9. The upper end of the connecting rod 10 is connected to the connecting block 8, and its lower end passes through and exceeds the base plate 1. The fastener 11 is detachably connected to the connecting rod 10 to limit the base plate 1.

[0044] In one embodiment, supports 12 for supporting the top rib 2 , the first side rib 3 and the second side rib 4 are provided on both sides of the bottom plate.

[0045] In one embodiment, each of the top rib 2, the first side rib 3 and the second side rib 4 is connected by a cable tie (not shown in the figure).

[0046] In a specific embodiment, the top reinforcement 2, first side reinforcement 3, and second side reinforcement 4 are all cylindrical structures made of fiber-reinforced composite materials. Fiber-reinforced composite materials, or FRP reinforcements, have the advantages of being non-magnetic, high-strength, corrosion-resistant, and low-cost. They can effectively reduce the rusting rate of the truss in offshore or marine environments, salt crystallization environments, and chemical corrosion environments, while also ensuring the truss's load-bearing capacity and extending its service life.

[0047] In one embodiment, epoxy resin and cable ties are used to connect the first support rib 5 to the top rib 2 and the first side rib 3, and the second support rib 6 to the top rib 2 and the second side rib 4 (not shown in the figure).

[0048] In a specific embodiment, the first support rib 5 and the second support rib 6 are made of fiber-reinforced composite material.

[0049] In a specific embodiment, the hanging rod 9 is shaped like a T.

[0050] In one embodiment, the upper end of the hanging rod 9 is symmetrically provided with a downward bending portion, which is used to hang the hanging rod 9 on the extension portion 7. The bending portion can increase the contact area between the hanging rod and the extension portion to achieve a better effect of fixing the extension portion.

[0051] In a specific embodiment, the lower end of the hanging rod 9 is threadedly connected to the connecting block 8 .

[0052] In a specific embodiment, mounting grooves 81 with internal threads for mounting the hanging rod 9 are symmetrically provided in the connecting block 8 .

[0053] In a specific embodiment, a groove 82 is provided in the connecting block 8 for limiting the upper end of the connecting rod 10 .

[0054] In a specific embodiment, the cross section of the fastener 11 is in the shape of an inverted trapezoid, so as to increase the contact area with the base plate and achieve effective support for the base plate.

[0055] When the truss floor deck structure of the present invention is in use, first, workers can erect the base plate at a certain height, and then place the connecting block correspondingly on the base plate, and make the connecting rod pass through and exceed the base plate, and then, place the extension part of the truss correspondingly above the connecting block, and then, make the lower end of the hanging rod pass through the extension part and threadedly connected to the installation groove of the connecting block, so that the extension part is tightly connected to the connecting block through the bending part of the hanging rod, and then, use fasteners to be sleeved on the connecting rod to tightly connect the base plate and the connecting block, finally, workers can apply the assembled truss floor deck structure to the construction building, and after the construction is completed, remove the fasteners to recycle the base plate.

[0056] The detachable FRP bar reinforced truss floor deck structure proposed by the utility model utilizes a connecting assembly consisting of a connecting block, a hanging rod, a connecting rod and a fastener, so that the extension portion is arranged on the connecting block and fixed by the hanging rod, the upper end of the connecting rod is connected to the connecting block, and the lower end thereof passes through and exceeds the base plate, and the fastener is detachably connected to the connecting rod to limit the base plate, so that the base plate can be disassembled and recycled by removing the fastener in the later stage of construction.

[0057] Furthermore, by making the top reinforcement, first side reinforcement, second side reinforcement, first support reinforcement and second support reinforcement all of fiber-reinforced composite materials, the rate at which the truss is corroded in offshore or marine environments, salt crystallization environments and chemical corrosion environments can be effectively reduced, and the bearing capacity of the truss can be guaranteed, thereby extending the service life of the truss.

[0058] To sum up, compared with the existing truss floor deck structure, the truss floor deck structure of the present invention can facilitate the recycling of the base plate to avoid waste of construction materials, and the connection component structure is simple and can be quickly installed and disassembled, thereby improving the processing efficiency of the truss floor deck and facilitating construction.

[0059] Although one or more embodiments of the present invention have been described above, it should be understood by those skilled in the art that the present invention can be implemented in any other form without departing from its spirit and scope. Therefore, the embodiments described above are illustrative and not restrictive, and many modifications and substitutions will be apparent to those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
