[0040] Referring to Figure 1 The concrete prefabricated slab structure provided by an embodiment of the present application includes a prefabricated section 10 and a connecting section 20. The connecting section 20 includes a connecting piece 210, and the two ends of the connecting piece 210 are respectively provided with connecting structures. The prefabricated section 10 includes an end plate 100, and the end plate 100 has a matching structure. The matching structures on the two end plates 100 of the two adjacent prefabricated sections 10 are connected one by one with the two connecting structures on one connecting piece 210.

[0041] In the embodiment, the prefabricated segment 10 has a matching structure. When two prefabricated segments 10 need to be connected, one end of the connecting piece 210 is matched with the matching structure of the end of one prefabricated segment 10 through the connecting structure, and the other end of the connecting piece 210 is matched with the matching structure of the end of the other prefabricated segment 10 through the connecting structure, so that the two prefabricated segments 10 can be connected. Due to the arrangement of the connecting piece 210, the connecting structure and the matching structure are connected, so that the long barb on the end plate 100 is not needed, the phenomenon of serious intersection and conflict between the barb and the surrounding component steel bar can be effectively avoided, the installation is simple, and the construction efficiency is high. In addition, the connecting piece 210 directly connects the two prefabricated segments 10, improves the transverse reinforcement ratio of the wet joint, and can improve the transverse bending stiffness and bending bearing capacity of the wet joint.

[0042] In some embodiments, the connecting piece 210 can be a steel bar, and the end plate 100 can be a steel plate.

[0043] In some embodiments, the connecting piece 210 can be a steel bar, and the end plate 100 can be a steel plate. Figure 2 The end plate 100 includes a vertical end plate 110 as a side wall of the prefabricated segment 10, and the matching structure includes a first hook-shaped piece 111 arranged on the vertical end plate 110. The connecting structure is a first bent hook 221, and the first bent hook 221 is hooked with the first hook-shaped piece 111.

[0044] In the embodiment, the vertical end plate 110 is vertically placed and can directly serve as the side wall of the prefabricated segment 10. The prefabricated segment 10 is completely manufactured in advance in a factory. When the prefabricated segment 10 is poured, the vertical end plate 110 can be directly used as a side mold of the prefabricated segment 10, without the need to additionally arrange a side mold, so that the production process is simplified, the construction efficiency is greatly improved, and the construction quality is easily guaranteed.

[0045] When the prefabricated segment 10 is prefabricated in the factory, the first hook-shaped piece 111 can be first welded on the vertical end plate 110, and then the vertical end plate 110 is used as a side mold for pouring. After pouring is completed, the vertical end plate 110 becomes the side wall of the prefabricated segment 10, and the first hook-shaped piece 111 is located outside the vertical end plate 110. In the prior art, a hole needs to be reserved for the barb on the side mold during prefabrication in the factory, and plugging is needed, which requires high precision control, large manual operation amount, and low production efficiency. The first hook-shaped piece 111 of the present application is directly welded on the vertical end plate 110 before pouring, without the need to reserve a hole, which is simple to operate and has high production efficiency. Moreover, the first hook-shaped pieces 111 on the two adjacent prefabricated segments 10 are connected through the connecting piece 210, so that reliable connection between the connecting piece 210 and the adjacent components can be ensured through the connecting piece 210, and thus the extension length of the first hook-shaped piece 111 can be greatly shortened, so that the conflict with the surrounding component steel bar can be avoided.

[0046] In order to improve the connection strength of the wet joint, a plurality of first hook-shaped members can be arranged on the vertical end plate along the thickness direction. The first hook-shaped member on each prefabricated segment is respectively hooked with the first hook of one end of the connecting member.

[0047] Further, in order to enhance the hooking stability of the first hook 221 and the first hook-shaped member 111, the first hook 221 and the first hook-shaped member 111 can be vertically hooked. Specifically, the hook of the first hook-shaped member 111 can be upwardly bent, and the hook type is a U-shaped structure, and the hook of the first hook 221 is horizontally bent. That is, when the first hook 221 of the connecting member 210 is hooked with the first hook-shaped member 111, the first hook 221 and the first hook-shaped member 111 will not be disconnected under the action of a large external force.

[0048] In one embodiment, the connecting member includes a body and a connecting structure arranged at both ends of the body. When the connecting structure is the first hook 221, the first hook 221 includes a first hook portion and a second hook portion, and the first hook portion and the second hook portion are arranged at an angle, specifically, the first hook portion and the second hook portion can be arranged at an angle of 45°, of course, it can also be 30° or 60°. The end of the first hook portion away from the second hook portion is connected with the body. The first hook portion and the second hook portion are arranged at an angle of 45°, which facilitates the rapid hooking of the first hook 221 and the first hook-shaped member 111.

[0049] In another embodiment, different from the above embodiment, the first hook portion and the second hook portion are parallel, and the first hook portion and the second hook portion are connected to form a U-shaped structure of the first hook 221. The U-shaped structure is conducive to the stable hooking of the first hook 221 and the first hook-shaped member 111.

[0050] In some other embodiments, the end plate 100 includes a horizontal rib plate 120 vertically connected with the vertical end plate 110, and the plate surface of the horizontal rib plate 120 is parallel to the plate surface of the prefabricated segment 10. The cooperating structure includes a first hole 121 opened on the horizontal rib plate 120, and the connecting structure is a second hook 222, and the second hook 222 is inserted into the first hole 121.

[0051] In this embodiment, by vertically connecting the horizontal rib plate 120 on the vertical end plate 110, and opening the first hole 121 on the horizontal rib plate 120, when connecting at the construction site, only the second hook 222 of the connecting member 210 needs to pass through the first hole 121 from above the first hole 121, without the need for welding or other mechanical connection, the operation is simple, and the connection efficiency is high. At this time, in order to facilitate the second hook 222 to pass through the first hole 121, the hook type of the second hook 222 can be an L-shaped structure.

[0052] Further, the vertical end plate 110 can be provided with multiple horizontal rib plates 120, and each horizontal rib plate 120 is provided with multiple first holes 121. Each first hole 121 on one side of the prefabricated section 10 is connected or optionally connected to a second hook 222 of a connecting structure.

[0053] In other embodiments, the prefabricated section 10 has a first surface 130 and a second surface 140 arranged in sequence along a first direction OX, and a horizontal rib plate 120 is arranged at one end of the vertical end plate 110 close to the first surface 130. The horizontal rib plate 120 is provided with multiple first holes 121 arranged in sequence along a second direction OY, and the first direction OX is perpendicular to the second direction OY. The vertical end plate 110 is provided with multiple first hook-shaped members 111 at one end close to the second surface 140, and the first holes 121 and the first hook-shaped members 111 are arranged one by one.

[0054] In the present embodiment, the first direction OX is the thickness direction of the concrete prefabricated slab, the second direction OY is the width direction of the concrete prefabricated slab, and multiple prefabricated sections 10 are connected along the length direction through connecting sections 20. The first surface 130 can be the upper surface of the concrete prefabricated slab, and correspondingly, the second surface 140 is the lower surface of the concrete prefabricated slab. The horizontal rib plate 120 is arranged at one end of the vertical end plate 110 close to the first surface 130, and the height of the horizontal rib plate 120 is lower than that of the upper surface, so as to facilitate the hooking of the second hook 222 of the connecting member 210 from the upper surface to the lower surface. When the concrete is poured, the horizontal rib plate 120 can be wrapped inside, that is, the horizontal rib plate 120 is arranged in a pre-embedded manner in the prefabricated section 10. The vertical end plate 110 is provided with multiple first hook-shaped members 111 at one end close to the second surface 140, and the first hook-shaped members 111 can be arranged close to the second surface 140, so as to improve the stress efficiency of the concrete prefabricated slab.

[0055] In some embodiments, the connecting section 20 further includes a steel cage 230 arranged between the connecting member 210 matched with the first hole 121 and the connecting member 210 matched with the first hook-shaped member 111. The steel cage 230 can be selectively spot-welded or tied with the connecting member 210, which has less on-site operation and is convenient for construction.

[0056] In some embodiments, the horizontal rib plate 120 extends to the outside of the vertical end plate 110 at both ends along a third direction OZ, and the third direction OZ is perpendicular to the first direction OX and the second direction OY. The horizontal rib plate 120 is provided with multiple second holes 122 at one end away from the connecting section 20, and the second holes 122 correspond to the first holes 121 in position and equal in number. The prefabricated section 10 includes multiple first longitudinal steel bars 150, and the first longitudinal steel bars 150 are hooked one by one to the second holes 122 and extend along the third direction OZ.

[0057] In the embodiment, the horizontal rib plate 120 can be divided into two parts and welded on both sides of the vertical end plate 110 along the third direction OZ, or the horizontal rib plate 120 can be a plurality of small steel plates, and the plurality of small steel plates are welded on the vertical end plate 110 respectively. The second holes 122 correspond to the first holes 121 in position and equal in number, and one end of the first longitudinal steel bars 150 has a hook structure same as that of the second hook 222, for hooking with the second holes 122 one by one, that is, the first longitudinal steel bars 150 in the adjacent two prefabricated plates are located on the same line and are connected with each other through the connecting piece 210, the force transmission of the longitudinal steel bars is continuous, and the connection effect is easy to guarantee.

[0058] Further, the vertical end plate 110 is provided with a plurality of second hook-shaped pieces 112 at the end away from the connecting section 20, and the second hook-shaped pieces 112 correspond to the first hook-shaped pieces 111 in position and equal in number.

[0059] In the embodiment, the second hook-shaped pieces 112 are welded on the vertical end plate 110, and one end of the second longitudinal steel bars 160 has a hook structure same as that of the first hook 221, for hooking with the second hook-shaped pieces 112. Similarly, the second hook-shaped pieces 112 correspond to the first hook-shaped pieces 111 in position and equal in number, and the second longitudinal steel bars 160 are hooked with the second hook-shaped pieces 112 one by one, that is, the second longitudinal steel bars 160 in the adjacent two prefabricated plates are located on the same line and are connected with each other through the connecting piece 210, so that the force transmission can be guaranteed.

[0060] Specifically, the prefabricated section 10 includes a plurality of transverse steel bars 170 extending along the second direction OY, and the surfaces of the first longitudinal steel bars 150 and the second longitudinal steel bars 160 close to each other are respectively provided with a plurality of transverse steel bars 170 arranged in sequence along the third direction OZ. The transverse steel bars 170 are tied with the first longitudinal steel bars 150 or the second longitudinal steel bars 160.

[0061] In combination with Figure 1 and Figure 2 , an embodiment of the present application further provides a construction method of the concrete prefabricated plate structure, and the construction method of the concrete prefabricated plate structure comprises the following steps:

[0062] prefabricating the prefabricated section 10;

[0065] pouring the connecting section 20 with concrete.

[0066] Due to the arrangement of the connecting member 210, the connecting structure and the matching structure are connected, so that the end plate 100 does not need to extend a long barb, which can effectively avoid the phenomenon of serious intersection and conflict between the barb and the surrounding component steel bar, and the installation is simple and the construction efficiency is high. In addition, the connecting member 210 directly connects the two prefabricated sections 10, improves the transverse reinforcement ratio of the wet joint, and can improve the transverse bending stiffness and bending bearing capacity of the wet joint.

[0067] Wherein the base plate 30 can be a wooden template or a steel beam upper flange with a shear connector. When the base plate is a wooden template, the wooden template is removed after pouring is completed. When the base plate is a steel beam upper flange with a shear connector, the concrete prefabricated slab is directly connected with the steel beam upper flange as a whole, directly as a part of the steel beam.

[0068] In one embodiment, the step of prefabricating the prefabricated section 10 includes:

[0069] A vertical end plate 110 and a horizontal rib plate 120 are arranged, the first hook-shaped member 111 and the second hook-shaped member 112 are connected on both sides of the vertical end plate 110 along the third direction OZ, and the first hole 121 and the second hole 122 are arranged on both sides of the horizontal rib plate 120 along the third direction OZ;

[0073] In this embodiment, the prefabricated section 10 is completely prefabricated in the factory in advance, the vertical end plate 110 can be directly used as the side mold of the prefabricated section 10, without the need to additionally arrange a side mold, which simplifies the production process, greatly improves the construction efficiency, and the construction quality is easy to be guaranteed.

[0074] In one embodiment, the specific steps of connecting the matching structure on one of the prefabricated sections 10 with the matching structure on another prefabricated section 10 through the connecting structure at both ends of the connecting member 210 further include:

[0077] The first hole 121 on the vertical end plate 110 of the adjacent two precast segments 10 is hooked by the second hook 222 at both ends of the connecting piece 210.

On the other hand, the setting of the connecting piece improves the transverse reinforcement ratio of the wet joint, and can improve the transverse bending stiffness and bending capacity of the wet joint.

In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.
