[0027] Many specific details are described in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation disclosed below.

[0028] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] refer to Figures 1 to 3 As shown, a concrete floor slab including a pre-embedded hanging point structure 2 is characterized in that the concrete floor slab including the pre-embedded hanging point structure 2 includes: a template 3, a concrete slab reinforcement 1 and a pre-embedded hanging point structure 2; the concrete slab reinforcement 1 is arranged above the template 3, the pre-embedded hanging point structure 2 is arranged between the concrete slab reinforcement 1 and the template 3, one end of the pre-embedded hanging point structure 2 is detachably connected to the concrete slab reinforcement 1, and the other end of the pre-embedded hanging point structure 2 is arranged on the template 3, the template 3 can support and stabilize the pre-embedded hanging point structure 2, and concrete can be poured between the template 3 and the concrete slab reinforcement 1 to make the pre-embedded hanging point structure 2 and the concrete slab reinforcement 1 integrated.

[0031] In this embodiment, the concrete floor slab has a pre-embedded hanging point structure 2 disposed between the concrete slab reinforcement 1 and the formwork 3, one end of the pre-embedded hanging point structure 2 is connected to the concrete slab reinforcement 1, and the other end of the pre-embedded hanging point structure 2 is placed on the formwork 3. When there is weight on the concrete slab reinforcement 1, the pre-embedded hanging point structure 2 is in contact with the formwork 3. The setting of the embedded hanging point structure 2 makes it unnecessary to set a concrete pad under the concrete slab reinforcement 1 before pouring concrete on the concrete floor, and the embedded hanging point structure 2 can not only replace the concrete pad, but also reserve a hanging point in the concrete floor that can be connected to the lifting screw rod after the template 3 is removed after the concrete is poured and fixed, avoiding the construction personnel from drilling holes twice when hoisting is required, avoiding the damage to the floor caused by the secondary drilling, and further improving the strength of the concrete floor. At the same time, since the embedded hanging point structure 2 is embedded in the concrete floor, the embedded hanging point structure 2 and the concrete floor are essentially integrated, which means that the hanging point formed by the embedded hanging point structure 2 is more firm and stable than the hanging point of the secondary drilling. Further, since the position of the hanging point is pre-set, the subsequent construction is more convenient. Moreover, the embedded hanging point structure 2 is easy to make, simple in structure, and complex in function, which is convenient for large-scale promotion and production in the field of construction.

[0032] like Figure 4 As shown, the embedded hanging point structure 2 includes: a fixing part and a hanging point part; the fixing part is detachably connected to the concrete slab reinforcement 1, the fixing part is fixedly connected to the hanging point part, the hanging point part is placed on the template 3, and the hanging point part can be connected to the screw rod. The fixing part includes a pair of binding steel bars 21, the binding steel bars 21 are bound and connected to the concrete slab reinforcement 1, the pairs of binding steel bars 21 are fixedly connected to the hanging point part, the pairs of binding steel bars 21 are connected and form a receiving groove that can accommodate concrete steel bars. The hanging point part includes a connecting piece and a hanging piece 22; the hanging piece 22 can be placed on the template 3, the hanging piece 22 is connected to the binding steel bars 21 through the connecting piece, and the hanging piece 22 can be connected to the screw rod.

[0033] In this embodiment, the embedded hanging point structure 2 is fixed to the bottom of the concrete slab reinforcement 1 by tying the steel bars 21, and is placed on the formwork 3 by the hanging parts 22 to connect the concrete slab reinforcement 1 and the formwork 3, filling the gap between the supporting concrete slab reinforcement 1 and the formwork 3. A receiving groove for accommodating the concrete slab reinforcement 1 is formed between the tying steel bars 21 to achieve the connection between the tying steel bars 21 and the longitudinal and transverse reinforcements of the concrete slab reinforcement 1. By setting the receiving groove, the embedded hanging point structure 2 can be connected to the longitudinal reinforcement in the concrete slab reinforcement 1 and the transverse reinforcement in the concrete slab reinforcement 1 structure, further ensuring the stability and firmness of the embedded hanging point structure 2. During the floor slab casting construction process, the erected concrete slab reinforcement 1 usually includes longitudinally arranged longitudinal reinforcements and transversely arranged transverse reinforcements to meet the stiffness and strength requirements of reinforced concrete. The inner wall of the hanging part 22 is provided with an internal thread that can cooperate with the screw rod. In a preferred embodiment, the hanging component 22 is preferably an internal threaded bolt. After the formwork 3 is disassembled, the internal threaded bolt embedded in the concrete can be used as a hanging point to connect with the hanging screw to hang other structures. In different hanging situations, the construction workers can make different selections of the hanging component 22 according to the different adaptability of the hanging structure.

[0034] Furthermore, brackets 221 are fixedly arranged around the hanging member 22, and the brackets 221 are placed on the template 3. The brackets 221 are integrally formed with the hanging member 22, and an anti-rust coating is arranged on the outer surface of the brackets 221. In this embodiment, the brackets 221 are preferably cross-galvanized brackets 221 connected with bolts.

[0035] Based on the above-mentioned embedded hanging point structure 2, in order to further clarify the advantages of the utility model, the following will introduce its better construction method:

[0036] ①According to the arrangement of the keels to be hoisted below, determine the approximate hanging point position of the screw rod and mark it on the template 3 with a marker;

[0037] ② The embedded hanging point structure 2 is placed under the plate reinforcement, and the bracket 221 in the embedded hanging point structure 2 is stably supported at the mark of the template 3;

[0038] ③ The binding steel bars 21 in the embedded hanging point structure 2 are connected with the plate reinforcement;

[0039] ④ After the embedded hanging point structure 2 is connected and fixed to the slab reinforcement, pour concrete between the formwork 3 and the concrete slab reinforcement 1;

[0040] ⑤ After the concrete strength reaches the standard, the formwork 3 is removed;

[0041] ⑥ There is a pre-buried lifting point structure 2 in the concrete floor slab to facilitate subsequent lifting construction.

[0042] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Therefore, the protection scope of the utility model patent shall be based on the attached claims.
