[0021] In order to describe the technical solution of the above utility model in more detail, specific embodiments are listed below to demonstrate the technical effect; it should be emphasized that these embodiments are used to illustrate the utility model but not to limit the scope of the utility model.
[0022] The utility model provides a steel structure floor deck and steel beam connection structure, such as Figures 1 to 4 As shown, the steel beam 10 includes a main steel beam 11 and a secondary steel beam 12. The main steel beam 11 is connected end to end to form a peripheral frame. In this embodiment, the peripheral frame is rectangular. Figure 1 As shown; the secondary steel beam 12 is set inside the outer frame, and the area enclosed by the outer frame is divided into a plurality of support plate areas. In this embodiment, the support plate area is also rectangular, such as Figure 1 As shown; the floor decking plate 20 corresponds to the covering area of the decking plate; the edge of the floor decking plate 20 is provided with a plurality of holes ( Figure 1 The holes overlap with the embedded bolts 13), and the main steel beams 11 and the secondary steel beams 12 constituting the deck area are respectively provided with a plurality of embedded bolts 13 corresponding to the holes. The utility model provides embedded bolts 13 on the steel beams 10, and opens holes on the floor deck 20, and utilizes the aligned insertion of the embedded bolts 13 and the holes, so as to facilitate the timely connection of the holes with the embedded bolts 13 on the steel beams 10 during the construction of the floor deck 20 of the steel structure, thereby improving the integrity and stability of the steel beams 10 and the floor deck 20, and then ensuring that when the upper part of the floor deck 20 is poured with concrete, the floor deck 20 has sufficient strength to meet the needs of the construction load, thereby ensuring construction safety, reducing the input of labor and materials, etc., and also reducing costs and accelerating the construction progress.
[0023] In some embodiments, please refer to Figure 3 , the embedded bolts 13 are welded to the main steel beams 11 and the secondary steel beams 12. Specifically, when the steel beams 10 of the steel structure are prefabricated, mounting holes for installing the embedded bolts 13 can be reserved on the steel beams 10, and the embedded bolts 13 can be bolted or welded in the mounting holes later. That is, the embedded bolts 13 can be installed on the ground before the steel beams 10 are hoisted, thereby reducing high-altitude operations and better ensuring the connection quality of the embedded bolts 13 on the steel beams 10.
[0024] In some embodiments, please refer to Figure 4The floor deck 20 includes a steel plate 21 and a steel truss 22. The steel plate 21 is laid above the deck area, and the holes are opened on the edge of the steel plate 21. The steel truss 22 is made of steel bars spliced in a corrugated form, and the steel truss 22 is fixed on the steel plate 21, that is, the steel truss 22 has a certain vertical height to form a space for pouring concrete. In addition, it should be noted that the steel truss 22 can be pre-made according to the size of the floor deck 20, and the steel truss 22 can be directly laid after the steel plate 21 is connected to the embedded bolts 13, which is convenient and quick to install.
[0025] In some embodiments, the thickness of the steel plate 21 is 0.5±0.1 mm, which can provide sufficient support for the upper steel frame truss 22 and concrete pouring without causing material waste.
[0026] In some embodiments, please refer to Figure 4 The steel truss 22 is composed of a first steel bar 23, a second steel bar 24 and a third steel bar 25. The first steel bar 23 includes a flange section and a diagonal bracing section. The flange section is attached to the steel plate 21 (such as fixed by welding), and the diagonal bracing section extends obliquely upward along the end of the flange section. The two first steel bars 23 are symmetrically arranged and spliced at the top. The second steel bar 24 is horizontally arranged at the top splicing of the two first steel bars 23. The third steel bar 25 is horizontally arranged at the connection between the flange section and the diagonal bracing section. Through the above combination, the steel truss 22 structure is obtained. When pouring concrete on the steel plate 21, a better tie can be formed to ensure that the steel beam 10 is firmly connected to the floor deck 20.
[0027] In some embodiments, after the embedded bolts 13 are aligned and connected with the steel beam 10, the steel truss 22 can be tied and fixed with the embedded bolts 13. Through the secondary tying, the connection between the steel beam 10 and the floor deck 20 is further ensured to be firm.
[0028] In some embodiments, after the embedded bolts 13 are aligned and connected with the steel beam 10, the embedded bolts 13 can be welded and fixed to the holes. By welding and fixing the embedded bolts 13 to the holes, it is further ensured that the steel beam 10 and the floor decking plate 20 are firmly connected.
[0029] The utility model achieves the purpose of transmitting the pressure of the floor deck 20 to the steel beam 10 by inserting the steel beam 10 and the floor deck 20 through the embedded bolts 13 and the holes, combining the secondary reinforcement binding of the steel truss 22 and the embedded bolts 13, or the welding of the embedded bolts 13 and the holes, ensuring that when pouring concrete on the floor deck 20, there is no need to add a support system at the bottom of the floor deck 20, thereby reducing costs and improving safety.
[0030] The specific implementation process of the steel structure floor deck and steel beam connection structure provided by the utility model can adopt the following scheme:
[0031] First, the embedded bolts 13 are pre-set on the steel beam 10; the steel plate 21 and the steel truss 22 are integrally prefabricated into a floor deck 20 with a width of 500 to 1000 mm, and spliced according to the overall floor width requirements;
[0032] Second, the embedded bolts 13 on the steel beam 10 are inserted into the corresponding holes on the steel plate 21 to complete the connection between the floor decking plate 20 and the steel beam 10. After the connection, the steel truss 22 and the embedded bolts 13 can be tied for a second time or the embedded bolts 13 and the holes on the floor decking plate 20 can be welded and reinforced, thereby effectively improving the strength of the connection;
[0033] Third, after the hidden inspection of the steel bars and the like is qualified, the upper part of the floor decking 20 can be poured with concrete, and the lower part of the floor decking 20 is free of support, and subsequent maintenance and decoration construction can be carried out.
[0034] In summary, the utility model provides a steel structure floor decking and steel beam connection structure, wherein the steel beam 10 includes a main steel beam 11 and a secondary steel beam 12, wherein the main steel beam 11 is connected end to end to form an outer frame, and the secondary steel beam 12 is erected inside the outer frame to divide the area enclosed by the outer frame into a plurality of decking areas, and the floor decking 20 is correspondingly covered on the decking areas; a plurality of holes are opened on the edge of the floor decking 20, and a plurality of pre-embedded bolts 13 corresponding to the holes are respectively provided on the main steel beam 11 and the secondary steel beam 12 constituting the decking area. The utility model arranges embedded bolts 13 on the steel beam 10 and opens holes on the floor decking 20, and utilizes the aligned insertion of the embedded bolts 13 and the holes to facilitate timely connection of the holes with the embedded bolts 13 on the steel beam 10 during the construction of the floor decking 20 of the steel structure, thereby improving the integrity and stability of the steel beam 10 and the floor decking 20, and then ensuring that when the concrete is poured on the upper part of the floor decking 20, the floor decking 20 has sufficient strength to meet the needs of the construction load, thereby ensuring construction safety, reducing the investment in labor, materials, etc., and also reducing costs and accelerating the construction progress.
