DETAILED DESCRIPTION

[0020] The technical solutions of the present application will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, but not all the embodiments.

[0021] The components of the embodiments of the present application generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application.

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those of ordinary skill in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0025] Embodiments As Figure 1 and Figure 2 The present application proposes a steel plate concrete composite slab with T-shaped beam, which comprises a bottom plate 1, and a plurality of groups of studs 2 welded on one side of the bottom plate 1. The studs 2 can enhance the connection strength between the bottom plate 1 and the concrete layer 7, and prevent relative slipping between the two.

[0026] As an implementation manner, the combination plate comprises the reinforcing beam 3 arranged on the bottom plate 1 close to the stud 2. The reinforcing beam 3 is arranged in an X-shaped special structure, or a plurality of transverse reinforcing beams 3 are welded together to form an X-shaped structure. The reinforcing beam 3 is in a T-shaped structure in the vertical direction, and the T-shaped reinforcing beam 3 can significantly improve the overall bending resistance. The reinforcing beam 3 comprises a reinforcing plate 31 arranged in parallel with the bottom plate 1, and two groups of webs 32 are arranged on the side of the reinforcing plate 31 close to the web 32. The web 32 is welded to the bottom plate 1, and the welding connection mode ensures the stability of the connection between the web 32 and the bottom plate 1, and provides reliable support for the reinforcing beam 3. A plurality of through holes 33 are arranged on the web 32, and the plurality of through holes 33 are arranged in an equidistant array. The reinforcing beam 3 divides a plurality of studs 2 into a plurality of regions, and the plurality of studs 2 in each region are arranged in an equidistant array. This partitioning arrangement can make the stud 2 bear force more evenly. Through the bending resistance of the reinforcing beam 3, direct punching shear resistance is provided, and the punching shear load area is dispersed to improve the punching shear resistance. The arrangement of the through hole 33 does not affect the arrangement of the first reinforcing bar 41 and the second reinforcing bar 42, and the integrity of the reinforcing bar structure is ensured.

[0027] Further, the combination plate further comprises a reinforcing mesh 4 arranged through the reinforcing beam 3. The reinforcing mesh 4 comprises a plurality of first reinforcing bars 41 and a plurality of second reinforcing bars 42. The second reinforcing bar 42 is arranged above the first reinforcing bar 41, and the plurality of first reinforcing bars 41 and the plurality of second reinforcing bars 42 are arranged in an equidistant array, respectively. The first reinforcing bar 41 and the second reinforcing bar 42 are arranged in the through hole 33. The arrangement of the reinforcing mesh 4 further enhances the overall structural strength of the combination plate and improves the anti-deformation capability.

[0028] Further, the combination plate further comprises a concrete layer 7 arranged on the bottom plate 1 close to the stud 2. The concrete layer 7 wraps the bottom plate 1, the stud 2, the reinforcing beam 3 and the reinforcing mesh 4 and other structures to form a whole force structure, and fully plays the synergistic effect of each component.

[0029] Specifically, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9The aforementioned combined plate also includes an adjusting mechanism 5 disposed on one side of the base plate 1. A positioning component 6 is inserted into the adjusting mechanism 5. The adjusting mechanism 5, in conjunction with the positioning component 6, positions multiple sets of bolts 2 to ensure the accuracy of the bolts 2 installation position. The adjusting mechanism 5 includes a positioning plate 51, which is L-shaped. The L-shape of the positioning plate 51 facilitates its positioning at the four corners of the base plate 1, improving the stability of the positioning plate 51 itself. A fixing block 52 is fixedly connected to the side of the fixing block 52 near the base plate 1. Multiple sets of adjusting blocks 53 are disposed on one side of the fixing block 52. A locking block 54 is disposed on the side of the multiple sets of adjusting blocks 53 away from the fixing block 52. A first slider 55 is fixedly connected to the multiple sets of adjusting blocks 53 and the locking block 54 near the positioning plate 51. First limiting blocks 56 are fixedly connected to both the upper and lower sides of the first slider 55. Both the first slider 55 and the first limiting blocks 56 are slidably connected to the positioning plate 51. The first limiting blocks 56 ensure that the first slider 55 slides smoothly within the positioning plate 51, preventing deviation during sliding. A first rotating shaft 57 is fixedly connected to the side of the positioning plate 51 away from the fixed block 52, and a first connecting plate 58 is rotatably connected to the first rotating shaft 57. Second rotating shafts 59 are fixedly connected to the sides of multiple sets of first sliders 55 away from the adjusting block 53, and second connecting plates 510 are rotatably connected to the second rotating shafts 59. Adjacent sets of second connecting plates 510 are rotatably connected, and the set of second connecting plates 510 closest to the first connecting plate 58 is rotatably connected to it. The arrangement of the second rotating shafts 59 and the second connecting plates 510 ensures that multiple sets of first sliders 55 move synchronously and maintain equal spacing, guaranteeing the uniformity of the spacing between the adjusting block 53 and the locking block 54. A synchronizing block 511 is fixedly connected to the side of the locking block 54 away from the adjusting block 53. The synchronizing block 511 moves synchronously with the locking block 54. When the position of the locking block 54 is fixed, the multiple sets of second connecting plates 510 cannot deflect, thereby ensuring the fixed position of the multiple sets of first sliders 55, and thus the fixed position of the adjusting block 53 and the locking block 54, ensuring stability after adjustment. A first screw 512 is threadedly connected to the synchronizing block 511. When the first screw 512 rotates, it moves along its own length direction, facilitating the adjustment of the fixed state of the locking block 54. The first screw 512 is slidably connected to the positioning plate 51. When the locking block 54 moves, it drives the first screw 512 to move synchronously in the positioning plate 51, ensuring the linkage between the first screw 512 and the locking block 54. A locking plate 513 is installed on the outer ring of the first screw 512. The locking plate 513 is L-shaped. A rubber pad 514 is installed on the side of the locking plate 513 near the positioning plate 51. After the first screw 512 is tightened, it moves the locking plate 513 closer to the positioning plate 51 and squeezes the rubber pad 514. The elastic deformation of the rubber pad 514 increases the friction, so that the position of the first screw 512 and the synchronization block 511 is fixed, thereby fixing the position of the locking block 54 and enhancing the locking effect.

[0030] Furthermore, such as Figure 3, Figure 4 , Figure 6 , Figure 7 as well as Figure 10As shown, the positioning component 6 in the above-mentioned combination plate includes an L-shaped fixed rod 61. A sleeve 62 is fixedly connected to one end of the fixed rod 61. A sliding rod 63 is slidably connected between the fixed rod 61 and the sleeve 62. The sliding rod 63 slides smoothly between the fixed rod 61 and the sleeve 62, allowing for flexible adjustment of the positioning range. A second screw 615 is threaded onto the sleeve 62. One end of the second screw 615 contacts the sliding rod 63. After tightening, the second screw 615 presses against the sliding rod 63, fixing its position through friction and ensuring stability after adjustment. A mounting rod 64 is fixedly connected to the end of the sliding rod 63 away from the fixed rod 61. When the mounting rod 64 moves, it drives the sliding rod 63 to move synchronously, facilitating operator control of the sliding rod 63's movement. A reinforcing block 65 is fixedly connected to the side of the fixing rod 61. The reinforcing block 65 has a T-shaped structure. The fixing rod 61 and the reinforcing block 65 are inserted into the fixing block 52, the adjusting block 53, or the locking block 54. The reinforcing block 65 increases the contact area between the fixing rod 61 and the inserted component, making the fixing rod 61 more secure after insertion. At the same time, by changing the insertion position of the fixing rod 61, the positioning of multiple rows of studs 2 can be achieved, enabling the sequential positioning and welding of multiple rows of studs 2. A first positioning block 66 is fixedly connected to the side of the fixing rod 61 near the stud 2. Multiple sets of second positioning blocks 67 are provided on the side of the sliding rod 63 near the stud 2. A second slider 68 is fixedly connected to the side of the second positioning block 67 away from the stud 2. Second limit blocks 69 are fixedly connected to both the upper and lower sides of the second slider 68. The second slider 68 and the second limit blocks 69 are slidably connected in the sliding rod 63. The setting of the second limit blocks 69 ensures that the second slider 68 moves smoothly in the sliding rod 63, guaranteeing the movement accuracy of the second positioning blocks 67. A third positioning block 610 is fixedly connected to the mounting rod 64 near the bolt 2. The first positioning block 66, the second positioning block 67, and the third positioning block 610 all have arc-shaped surfaces near the bolt 2. These arc-shaped surfaces adapt to the shape of the bolt 2, allowing the bolt 2 to be quickly positioned near the arc-shaped surface, facilitating welding and improving welding efficiency and precision. A third rotating shaft 611 is fixedly connected to the fixing rod 61 and the mounting rod 64 on the side away from the bolt 2, respectively. A third connecting plate 612 is rotatably connected to the third rotating shaft 611. A fourth rotating shaft 613 is fixedly connected to the side of the multiple sets of second sliders 68 away from the bolts 2. A fourth connecting plate 614 is rotatably connected to the fourth rotating shaft 613. Two adjacent sets of fourth connecting plates 614 are rotatably connected. The third connecting plate 612 is rotatably connected to the set of fourth connecting plates 614 closest to it. Through the arrangement of the fourth rotating shaft 613 and the fourth connecting plate 614, the multiple sets of third connecting plates 612 and fourth connecting plates 614 are synchronously deflected, thereby ensuring that the third rotating shaft 611 and the fourth rotating shaft 613 move synchronously. Thus, the first positioning block 66, the second positioning block 67 and the third positioning block 610 always maintain equal spacing, ensuring that the bolts 2 are equidistantly arranged, improving the strength of the combined plate, and ensuring that each bolt 2 is subjected to uniform force.

[0031] In this embodiment, the L-shaped positioning plate 51 is fixed at the four corners of the base plate 1 to achieve precise positioning. The fixing block 52, adjusting block 53 and locking block 54 are slidably connected to the positioning plate 51 through the first slider 55. Under the linkage of the second rotating shaft 59 and the second connecting plate 510, multiple sets of first sliders 55 can move synchronously and maintain equal spacing. By rotating the first screw 512, the locking plate 513 is driven to squeeze the rubber pad 514, which can lock the position of the adjusting block 53 and the locking block 54, thereby achieving precise adjustment of the lateral spacing. Next, the fixing rod 61 and the reinforcing block 65 are inserted into the positioning plate 51. The sliding rod 63 slides within the sleeve 62 and is fixed by the second screw 615. With the linkage of the third rotating shaft 611, the third connecting plate 612, the fourth rotating shaft 613, and the fourth connecting plate 614, the first positioning block 66, the second positioning block 67, and the third positioning block 610 are equidistantly distributed. Their arc-shaped surfaces can quickly position the studs 2, ensuring uniform longitudinal spacing during welding. Ultimately, this achieves an equidistant array distribution of multiple sets of studs 2, laying the foundation for uniform force distribution later. Then, the fixing rod 61 and the reinforcing block 65 are pulled out of the positioning plate 51 and sequentially inserted into the adjusting block 53 and the locking block 54. Simultaneously, the welding of multiple rows of studs 2 is completed sequentially, resulting in an equidistant array distribution of multiple sets of studs 2.

[0032] After the concrete layer 7 is poured, all components such as the base plate 1, studs 2, reinforcing beams 3, and reinforcing mesh 4 are wrapped and integrated to form a complete load-bearing whole. Through the functional synergy of each component, the advantages of the steel plate concrete composite structure are fully utilized. While improving the load-bearing capacity, ductility, and ease of construction, the punching shear failure problem of special plate-column joints is specifically solved.

[0033] The above specific embodiments are merely optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
