As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, 2 and 3, a laminated floor slab 100 according to an embodiment of the present invention includes a prefabricated layer 10 and a reinforcement assembly 20 (see fig. 3) embedded in the prefabricated layer 10.
The reinforcing bar assembly 20 includes a plurality of first and second reinforcing bars 21 and 22 disposed to cross each other. The first ribs 21 are arranged at intervals along the first direction a, and each first rib 21 is perpendicular to the first direction a. The second ribs 22 are arranged at intervals along a second direction b which forms an angle with the first direction a, and each second rib 22 is perpendicular to the second direction b. In particular, in the embodiment, the first direction a is perpendicular to the second direction b.
At least one end of each first and/or second reinforcement 21, 22 is inclined with respect to the plane formed by the first and second directions a, b and extends out from the edge of the top surface 12 of the prefabricated layer 10.
In the composite floor slab 100, when the prefabricated layer 10 is formed, a plurality of mold ribs 200 are used to enclose a casting space for casting the prefabricated layer 10, and the first plate reinforcement 21 and the second plate reinforcement 22 are arranged in the casting space before casting. At least one end of each first and/or second reinforcement 21, 22 is inclined with respect to the plane formed by the first and second directions a, b and extends out from the edge of the top surface 12 of the prefabricated layer 10 of the laminated floor slab 100. Therefore, the mold rib 200 does not need to provide a through hole for the first plate rib 21 or the second plate rib 22 to penetrate through, so that the universality of the mold is improved, the processing cost and the turnover cost of the mold are reduced, and the production cost of the composite floor slab 100 is further reduced.
In the embodiment shown in fig. 1, it is understood that the first direction a and the second direction b form a plane parallel to the top surface 12 of the preform layer 10.
In particular, in one embodiment, the prefabricated layers 10 of the composite floor slab 100 are rectangular. The opposite ends of each first and second stud 21, 22 respectively extend out from the periphery of the top surface 12 of the prefabricated layer 10, so that the four mold flanges 200 for molding the prefabricated layer 10 do not need to be provided with through holes for the first and second studs 21, 22 to pass through.
In the embodiment of the present invention, each first rib 21 includes a first rib body 211 perpendicular to the first direction a and a first bending portion 213 fixedly connected to at least one end of the first rib body 211. The first bending portion 213 is disposed obliquely to a plane formed by the first direction a and the second direction b and extends out from an edge of the top surface 12 of the preform layer 10.
In particular embodiments, each first stud 21 further includes a first parallel portion 215. One end of the first parallel portion 215 is fixedly connected to one end of the first bending portion 213 away from the first rib body 211, and the first parallel portion 215 is parallel to the first rib body 211. In this way, when the composite floor 100 is assembled, the first parallel parts 215 are conveniently penetrated into other structures (such as walls, beams and the like) to realize the assembly of the composite floor 100.
It should be noted that, when the composite floor slab 100 is assembled, the first bending portion 213 is subjected to a bending moment load, so on the one hand, if the inclination angle of the first bending portion 213 is too large, the ability of the composite floor slab 100 to bear the bending moment is affected; on the other hand, if the inclination angle of the first bending portion 213 is too small, the first bending portion 213 cannot be ensured to penetrate through the edge of the top surface 12 of the precast layer 10, and the purpose of avoiding the through hole of the rib 200 cannot be achieved. Therefore, in one embodiment, the first bent portion 213 is inclined at an angle of 8 ° to 10 ° with respect to a plane formed by the first and second directions a and b. Preferably, the first bent portion 213 is inclined at an angle of 9 ° with respect to a plane formed by the first and second directions a and b.
In the embodiment of the present invention, each second plate rib 22 includes a second rib body 222 perpendicular to the second direction b and a second bending portion 224 fixedly connected to at least one end of the second rib body 222.

In particular embodiments, each second stud 22 further includes a second parallel portion 226. One end of the second parallel portion 226 is fixedly connected to an end of the second bending portion 224 away from the second bead body 222. The second parallel portion 226 is parallel to the second stud body 222. In this manner, when assembling the composite floor 100, it is convenient to use the second parallel portion 226 to penetrate into other structures (e.g., walls, beams, etc.) to achieve the assembly of the composite floor 100.
It should be noted that, when the composite floor slab 100 is assembled, the second bending portion 224 bears the bending moment load, so on the one hand, if the inclination angle of the second bending portion 224 is too large, the ability of the composite floor slab 100 to bear the bending moment is affected; on the other hand, if the angle of inclination of the second bending portion 224 is too small, the second bending portion 224 cannot be ensured to penetrate through the edge of the top surface 12 of the prefabricated layer 10, so that the purpose of avoiding the through hole of the rib 200 cannot be achieved. Accordingly, in one embodiment, the second bent portion 224 is inclined at an angle of 8 ° to 10 ° from a plane formed by the first and second directions a and b. Preferably, the second bending part 224 is inclined at an angle of 9 ° with respect to a plane formed by the first and second directions a and b.
In the embodiment of the present invention, the first plate rib body 211, the first bending portion 213 and the first parallel portion 215 are integrally formed by bending a steel bar, so as to be beneficial to ensuring the structural strength of the first plate rib 21 and improving the strength of the composite floor slab 100.
The second plate rib body 222, the second bending portion 224 and the second parallel portion 226 are integrally formed by bending a steel bar, so that the structural strength of the second plate rib 22 is ensured, and the strength of the composite floor slab 100 is improved.
In an embodiment of the present invention, the rebar assembly 20 further includes a plurality of truss bars 23. The plurality of truss ribs 23 are arranged at intervals along the first direction a, and each truss rib 23 is perpendicular to the first direction a and exposed to the top surface 12 of the precast layer 10.

In an embodiment of the invention, the composite floor 100 further comprises at least two floor lifting loops 30 for lifting the floor. Each floor lifting ring 30 is partially embedded in the precast layer 10 and extends out from the top surface 12 of the precast layer 10. The part of each floor slab lifting ring 30 pre-embedded in the precast layer 10 is fixedly connected to the first and/or second plate bars 21, 22. Optionally, the part of the floor slab lifting ring 30 embedded in the precast layer 10 can be welded and connected to the first plate bar 21 and/or the second plate bar 22, the welding process is mature, and the operation is simple.
