Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] The purpose of this utility model is to provide a prefabricated assembly component embedded part and its lifting device to solve the problems existing in the prior art and to easily lift the prefabricated assembly component body.
[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] Example 1
[0030] like Figures 1-2 As shown, this embodiment provides a prefabricated assembly component embedded part, including an embedded part body 3. The embedded part body 3 is fixed in the embedded groove 2 of the prefabricated assembly component body 1. Specifically, when casting the prefabricated assembly component body 1, the embedded part body 3 can be cast and fixed together with it. Regarding the shape of the embedded part body 3, from... Figure 2As can be seen from the diagram, the embedded part body 3 includes a large embedded part 301 and a small embedded part 302. The large embedded part 301 and the small embedded part 302 are fixedly connected, which can be an integral structure. The large embedded part 301 is located on the outside and the small embedded part 302 is located on the inside (i.e., close to the bottom of the groove 2). The end of the small embedded part 302 away from the large embedded part 301 is fixed in the prefabricated assembled component body 1, while the large embedded part 301 and the prefabricated assembled component body 1 may not be in contact.
[0031] In this embodiment, the pre-embedded groove 2 is a hemispherical groove. Of course, those skilled in the art can also adjust it to other shapes of groove structures, such as elliptical grooves. Therefore, the shape and size of the pre-embedded groove 2 are not limited here.
[0032] In this embodiment, both the large end 301 and the small end 302 of the embedded part are cylindrical structures. The diameter of the large end 301 is larger than the diameter of the small end 302, and the height (i.e., length) of the large end 301 is smaller than the height (i.e., length) of the small end 302. Figure 2 As can be seen, the embedded part body 3 is similar to a bolt-shaped structure, and can even use existing bolt structures.
[0033] In other embodiments, the large end 301 of the embedded part can also be a regular polygonal prism structure, such as a hexagonal prism (the same as the end of the bolt), or an octagonal prism, etc.
[0034] In this embodiment, the prefabricated assembly component body 1 is a crash barrier for a bridge or highway, but it can also be other building components, and is not limited to this one. The number and distribution of the pre-embedded grooves 2 provided on the prefabricated assembly component body 1 can be adjusted according to the actual situation, so they are not limited here.
[0035] Example 2
[0036] like Figures 3-5 As shown, this embodiment provides a lifting device for prefabricated assembled component embedded parts, including the prefabricated assembled component embedded parts disclosed in Embodiment 1, the difference being that:
[0037] In this embodiment, the device also includes a lifting body 4, which is rotatably connected to a lifting ring 5. Specifically, the lifting body 4 has a through hole through which one end of the lifting ring 5 can pass. The lifting ring 5 can be rotatably connected by passing one side through the through hole. The lifting body 4 has a lifting slot 6, and the large end 301 of the embedded part extends into the lifting slot 6. The two sides of the slot 6 can be respectively engaged with the two sides of the small end 302 of the embedded part.
[0038] In actual use, the large end 301 of the embedded part needs to be inserted into the inside of the lifting slot 6 along one end of the lifting slot 6. The two sides of the opening of the lifting slot 6 can be located on both sides of the small end 302 of the embedded part. Then, the lifting ring 5 is connected to the crane to carry out the lifting work of the prefabricated assembly component body 1.
[0039] In this embodiment, the lifting slot 6 includes a wide lifting slot 601 and a narrow lifting slot 602, which are connected. When connecting to the embedded part body 3, the large end 301 of the embedded part needs to be inserted into the wide lifting slot 601 first and then moved to the narrow lifting slot 602. This arrangement facilitates the installation of the large end 301 of the embedded part.
[0040] In this embodiment, there is one or two lifting wide slots 601. When there is one lifting wide slot 601, it can be set at one end of the lifting narrow slot 602; when there are two lifting wide slots 601, the two lifting wide slots 601 are respectively set at both ends of the lifting narrow slot 602, and can be connected from either end when installing the embedded part big end 301.
[0041] In this embodiment, as Figure 3 , Figure 5 As shown, the width of the lifting wide slot 601 is greater than the diameter of the large end 301 of the embedded part, thus facilitating the insertion of the large end 301 of the embedded part. The width of the lifting narrow slot 602 is less than the diameter of the large end 301 of the embedded part, but greater than the diameter of the small end 302 of the embedded part, so that the lifting slot 6 can engage with both sides of the small end 302 of the embedded part and the lower end of the large end 301 of the embedded part, thereby supporting the embedded part body 3 and the prefabricated assembled component body 1 connected thereto.
[0042] In this embodiment, one end of the lifting device body 4 is fixed with an abutment limiting part 7. The abutment limiting part 7 and the lifting device body 4 are integral structures, and the lower surface of the abutment limiting part 7 is a plane. When the lifting device body 4 is engaged with the embedded part body 3, the abutment limiting part 7 abuts against the prefabricated assembled component body 1.
[0043] When the lifting device body 4 is fixed to the embedded part body 3, the crane connects to the lifting ring 5 to lift the prefabricated assembly component body 1. During the lifting process, the abutment limiting part 7 abuts against the prefabricated assembly component body 1, thereby preventing mutual movement between the lifting device body 4 and the embedded part body 3, thus ensuring stability and safety during the lifting process.
[0044] In this embodiment, the lifting body 4 and the limiting part 7 and the lifting ring 5 are both made of stainless steel. Of course, those skilled in the art can replace them with other materials according to actual needs, and are not limited to this one.
