Description

Technical Field

[0001] The present application relates to the technical field of floor deck processing, and in particular to a corrugated steel floor deck structure. Background Art

[0002] Corrugated steel floor decking, also known as truss floor decking, is a type of unsupported corrugated composite floor decking. The truss and corrugated steel plate structure in the prior art is usually prefabricated in the factory, and then the corrugated steel plate is fixed to the steel beam by bolts at the construction site, and then the truss is installed and tied, and finally concrete is poured to complete the construction.

[0003] During the concrete pouring process, it needs to withstand great pressure. However, in order to facilitate production and processing and save costs, the existing corrugated steel sheets are relatively thin and lack strength. The connection density between the corrugated steel sheets and the steel beams is poor, and the force borne on the trusses cannot be evenly transmitted to the steel beams, which eventually leads to the breakage of the corrugated steel sheets and trusses due to insufficient strength. Summary of the invention

[0004] In order to further enhance the overall structural stability of the corrugated steel floor deck, the present application provides a corrugated steel floor deck structure.

[0005] The present application provides a corrugated steel floor deck structure, which adopts the following technical solution:

[0006] A corrugated steel floor decking structure comprises a corrugated steel plate, wherein the corrugated steel plate comprises a protruding portion, a recessed portion and a connecting portion, wherein a plurality of the protruding portions and a plurality of the connecting portions are provided, and the plurality of the protruding portions and the plurality of the recessed portions are sequentially and spaced apart and distributed on the same side of the connecting portion, so that each of the protruding portions and each of the connecting portions are arranged side by side, a first distribution rib is fixed at the inner cavity of the connecting portion along its length direction, a second distribution rib is fixed at the inner cavity of the protruding portion along its length direction, and a third distribution rib is fixed at the inner cavity of the recessed portion along its length direction.

[0007] By adopting the above technical scheme, the cooperation of the protrusion, the recessed portion and the connecting portion makes the floor decking plate have better load-bearing performance while maintaining its lightweight. The arrangement of the first distribution ribs, the second distribution ribs and the third distribution ribs further enhances the stability and durability of the floor decking plate, and can improve the safety and reliability of the corrugated steel plate under long-term use. Compared with the prior art, the present application has effectively improved the structural strength of the corrugated steel plate through ingenious structural improvements. During the concrete pouring process, the stress concentration of the corrugated steel plate is reduced to avoid breakage due to insufficient strength, which helps to extend the service life of the corrugated steel floor decking plate.

[0008] Preferably, a first reinforcement groove is pressed inwardly on a side of the protruding portion away from the connecting portion, and a second reinforcement groove is pressed outwardly on a side of the recessed portion away from the connecting portion.

[0009] By adopting the above technical scheme, a first reinforcement groove is formed by pressing inward on the side of the protruding portion away from the connecting portion, and a second reinforcement groove is formed by pressing outward on the side of the recessed portion away from the connecting portion. This can optimize the stress distribution of the floor decking and reduce possible deformation and damage during use, thereby further improving the local strength and rigidity of the corrugated steel floor decking and extending the service life of the floor decking.

[0010] Preferably, there are a plurality of the third distribution ribs, and the plurality of the third distribution ribs are evenly arranged along the inner cavity peripheral wall of the recessed portion.

[0011] By adopting the above technical solution, the evenly distributed third distribution reinforcement can transfer force more evenly when the floor deck is subjected to load, thus avoiding the occurrence of stress concentration, improving the bearing capacity of the floor deck, ensuring its safety performance during use, and making the structure of the corrugated steel plate more stable and reliable.

[0012] Preferably, the protruding portion is a trapezoidal structure, and the recessed portion is a trapezoidal groove.

[0013] By adopting the above technical solution, the protruding part of the trapezoidal structure has better load-bearing capacity, while the recessed part of the trapezoidal groove provides a larger space to accommodate the distribution reinforcement, which can optimize the mechanical properties of the floor decking, thereby further improving the overall performance of the floor decking.

[0014] Preferably, it comprises a steel beam, the corrugated steel plate is arranged on the steel beam, the length direction of the corrugated steel plate is consistent with that of the steel beam, and the connecting portion is pressed against the top surface of the steel beam.

[0015] By adopting the above technical solution, the corrugated steel plate is set on the steel beam, and it is ensured that the length direction of the corrugated steel plate is consistent with that of the steel beam, and at the same time, the connecting part is pressed against the top surface of the steel beam. Such a design allows the floor decking plate to fit tightly on the steel beam, thereby effectively transferring the load and reducing deformation, and can improve the stability of the connection between the floor decking plate and the steel beam.

[0016] Preferably, it comprises a plurality of welding nails, each of which corresponds to and vertically passes through the connecting portion, and the bottom end of the welding nail is welded and fixed to the steel beam.

[0017] By adopting the above technical solution, a plurality of welding nails are introduced and vertically passed through the connecting part to be welded and fixed to the steel beam. The strong welding of the welding nails enables the floor deck to fit closely to the steel beam, effectively transfer the load, and reduce the displacement or deformation caused by external force, thereby improving the stability and safety of the overall structure and enhancing the connection stability between the corrugated steel floor deck and the steel beam.

[0018] Preferably, it includes a steel plate edging, which is an "L"-shaped structure, wherein the inner wall of the short side of the steel plate edging abuts against the height side wall of the outermost connecting part, and the inner wall of the long side of the steel plate edging abuts against the wide side wall of the outermost connecting part, and extends to the top surface of the steel beam.

[0019] By adopting the above technical solution, the steel plate edging of the "L"-shaped structure cleverly reinforces and protects the edge of the corrugated steel floor deck. The close contact between the steel plate edging and the high side wall and wide side wall of the joint not only enhances the edge strength of the floor deck, but also effectively prevents wear and damage to the edge. In addition, the design of the steel plate edging extending to the top surface of the steel beam further enhances the integrity of the connection between the floor deck and the steel beam, ensuring the stability and durability of the structure.

[0020] Preferably, a reinforcing sheet is included, the reinforcing sheet is welded and fixed to the connecting portion, and the inner cavity of the protruding portion faces the reinforcing sheet.

[0021] By adopting the above technical solution, the introduction of the reinforcement plate provides additional support for the joint, effectively disperses the load transmitted by the protrusion, thereby reducing stress concentration and deformation risks. The reinforcement plate is welded at the joint and the inner cavity of the protrusion is directed toward the reinforcement plate, which helps to improve the local bearing capacity of the corrugated steel floor decking and optimize the force distribution of the floor decking, thereby extending its service life.

[0022] Preferably, it comprises an angle steel, the extension direction of the angle steel is perpendicular to the extension direction of the protrusions of the corrugated steel plate, and the angle steel is welded to a plurality of the protrusions at the same time.

[0023] By adopting the above technical solution, the introduction of angle steel, whose extension direction is perpendicular to the protrusions of the corrugated steel plate and welded to multiple protrusions, can improve the overall stiffness and torsional resistance of the floor decking. The angle steel, as a solid supporting member, can effectively resist external torque and reduce the vibration and deformation of the floor decking during use. At the same time, the welding connection with multiple protrusions also enhances the integrity and stability of the structure.

[0024] Preferably, a reserved tube is included, the reserved tube vertically passes through the connecting portion at the recessed portion and simultaneously passes through the reinforcing sheet, and the reserved tube is respectively fixed to the reinforcing sheet and the connecting portion by welding.

[0025] By adopting the above technical solution, a reserved pipe is vertically inserted into the connecting portion at the recessed portion, and is simultaneously passed through the reinforcement plate for welding and fixing. The reserved pipe facilitates the installation of subsequent pipelines or equipment, and welding fixation ensures a firm connection between the reserved pipe and the floor decking plate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Compared with the prior art, the present invention has effectively improved the structural strength of the corrugated steel plate through ingenious structural improvement, and reduced the stress concentration of the corrugated steel plate during the concrete pouring process, so as to avoid the breakage due to insufficient strength, which helps to extend the service life of the corrugated steel floor deck;

[0028] 2. Introduce multiple welding nails and make them pass vertically through the connecting parts and weld them to the steel beams. The strong welding of the welding nails enables the floor deck to fit the steel beams closely, effectively transfer the load, and reduce the displacement or deformation caused by external forces, thereby improving the stability and safety of the overall structure and enhancing the connection stability between the corrugated steel floor deck and the steel beams;

[0029] 3. The introduction of reinforcement plates provides additional support for the joints, effectively disperses the load transmitted by the protrusions, thereby reducing stress concentration and deformation risks. Welding reinforcement plates at the joints and making the inner cavity of the protrusions face the reinforcement plates can help improve the local bearing capacity of the corrugated steel floor decking, optimize the force distribution of the floor decking, and thus extend its service life.

[0038] The following is combined with Figure 1-7 This application is described in further detail.

[0039] The embodiment of the present application discloses a corrugated steel floor deck structure.

[0040] Reference Figure 1 and Figure 2 A corrugated steel floor deck structure comprises a corrugated steel plate 1, wherein the corrugated steel plate 1 comprises a protruding portion 11, a recessed portion 12 and a connecting portion 13, wherein a plurality of protruding portions 11 and a plurality of recessed portions 12 are arranged in sequence and at intervals on the same side of the connecting portion 13, so that each protruding portion 11 and each connecting portion 13 are arranged in parallel, a first distribution rib 14 is fixed at the inner cavity of the connecting portion 13 along its length direction, a second distribution rib 15 is fixed at the inner cavity of the protruding portion 11 along its length direction, a third distribution rib 16 is fixed at the inner cavity of the recessed portion 12 along its length direction, there are a plurality of third distribution ribs 16, and the plurality of third distribution ribs 16 are evenly arranged along the inner cavity peripheral wall of the recessed portion 12, so that the floor deck can transmit force more evenly when bearing load, thereby improving the bearing capacity of the floor deck.

[0041] Specifically, the protrusion 11 in the present application is a trapezoidal structure, and the recessed portion 12 is a trapezoidal groove. Such a design can make the protrusion 11 have a better load-bearing capacity, and the recessed portion 12 of the trapezoidal groove provides a larger space to accommodate the distribution reinforcement, which can optimize the mechanical properties of the floor decking, thereby further improving the overall performance of the floor decking.

[0042] Furthermore, in the present application, through ingenious structural improvements, the structural strength of the corrugated steel sheet 1 is effectively improved, and during the concrete pouring process, the stress concentration of the corrugated steel sheet 1 is reduced. With the cooperation of the protrusion 11, the recessed portion 12 and the connecting portion 13, the floor decking plate has better load-bearing performance while maintaining its lightness. The arrangement of the first distribution ribs 14, the second distribution ribs 15 and the third distribution ribs 16 further enhances the stability and durability of the floor decking plate, and can improve the safety and reliability of the corrugated steel sheet 1 under long-term use.

[0043] A first reinforcing groove 17 is pressed inward on the side of the protruding portion 11 away from the connecting portion 13, and a second reinforcing groove 18 is pressed outward on the side of the recessed portion 12 away from the connecting portion 13. This can optimize the stress distribution of the floor decking to a certain extent, reduce the deformation and damage that may occur during use, and further improve the local strength and rigidity of the corrugated steel floor decking.

[0044] Reference Figure 2 and Figure 3 In the present application, the corrugated steel floor decking structure also includes a steel beam 2, a welding nail 3, a steel plate edging 4, a reinforcing sheet 5, an angle steel 6 and a reserved pipe 7, wherein the reinforcing sheet 5 is a rectangular plate structure, the reinforcing sheet 5 is welded and fixed to the connecting portion 13, the inner cavity of the protrusion 11 faces the reinforcing sheet 5, so that the reinforcing sheet 5 is distributed on one side close to the peak of the recessed portion 12, and the introduction of the reinforcing sheet 5 provides additional support for the connecting portion 13, effectively dispersing the load transmitted by the protrusion 11, thereby reducing stress concentration and deformation risks, and helping to improve the local bearing capacity of the corrugated steel floor decking.

[0045] The steel beam 2 is an "I" shaped steel, and the corrugated steel plate 1 is arranged on the steel beam 2 so that the length direction of the corrugated steel plate 1 is consistent with that of the steel beam 2. The connecting portion 13 is pressed against the top surface of the steel beam 2. The steel plate edge 4 is an "L" shaped structure, which can reinforce and protect the edge of the corrugated steel floor deck. The steel plate edge 4 (refer to Figure 4 )'s short side inner wall abuts against the height side wall of the outermost connecting portion 13, and the long side inner wall of the steel plate edging 4 abuts against the wide side wall of the outermost connecting portion 13, and at the same time extends to the top surface of the steel beam 2. The tight abutment between the steel plate edging 4 and the height side wall and wide side wall of the connecting portion 13 can enhance the edge strength of the floor decking, reduce edge wear and damage, further enhance the integrity of the connection between the floor decking and the steel beam 2, and make the structure more stable and durable.

[0046] There are multiple welding nails 3, each welding nail 3 corresponds to and vertically passes through the connecting part 13, and the bottom end of the welding nail 3 is welded and fixed to the steel beam 2. Under the joint action of multiple welding nails 3, the floor decking plate can fit tightly on the steel beam 2, effectively transfer the load, and reduce the displacement or deformation caused by external force, thereby improving the stability and safety of the overall structure.

[0047] Reference Figure 6 and Figure 7The reserved pipe 7 vertically passes through the connecting portion 13 at the recessed portion 12, and passes through the reinforcing sheet 5 at the same time. In the present application, the insertion directions of the welding nail 3 and the reserved pipe 7 are consistent, and both are inserted from the peak of the protruding portion 11 to the peak of the recessed portion 12. Both are placed in the recessed portion 12. The reserved pipe 7 is welded and fixed to the reinforcing sheet 5 and the connecting portion 13 respectively. The reserved pipe 7 provides convenience for the installation of subsequent pipelines or equipment. The reserved pipe 7 can also be used as a drainage tool to drain the accumulated water on the corrugated steel plate 1. By welding and fixing, the firm connection between the reserved pipe 7 and the floor decking can be ensured, thereby improving the overall connection stability.

[0048] In addition, refer to Figure 5 The extension direction of the angle steel 6 is perpendicular to the extension direction of the protrusion 11 of the corrugated steel plate 1. The angle steel 6 is welded to multiple protrusions 11 at the same time, which can improve the overall stiffness and torsional resistance of the floor deck. As a solid supporting member, the angle steel 6 can effectively resist external torque and reduce the vibration and deformation of the floor deck during use. At the same time, the welding connection with multiple protrusions 11 also enhances the integrity and stability of the structure.
