[0002] In the PCTF (Precast Concrete Cast-in-Place) system, tower crane wall-mounted installation requires the construction of an operating platform on the exterior facade. During tower crane wall-mounted installation in the PCTF system, some wall-mounted locations are limited by the tower crane's position and wall height, and are far from window openings, flower beds, or other suitable areas for erecting an operating platform. In such cases, a relatively long aerial platform needs to be extended from the opening, a technically challenging and high-risk approach. The traditional method is to erect a steel pipe and coupler-type operating platform; however, this method is complex to construct and presents safety issues during erection.
[0003] In view of the shortcomings of the existing steel pipe fastener type operating platform, those skilled in the art have been looking for solutions. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an external standardized operating platform suitable for the PCTF system. The external standardized operating platform suitable for the PCTF system includes: a standardized operating platform and several embedded parts. A portion of each embedded part is embedded in a precast component.

[0032] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the plug-in standardized operating platform suitable for the PCTF system proposed in this utility model. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0034] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of a utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0036] In utility models, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.
[0037] Please refer to Figures 1 to 5 The standardized external operating platform for the PCTF system includes a standardized operating platform 100 and several embedded parts 200. A portion of each embedded part 200 is embedded in a precast component. The anchoring end of the standardized operating platform 100 is inserted into the closed end of the embedded part 200 exposed in the precast component, so that the standardized operating platform 100 is externally mounted on the outside of the precast component. Here, the closed end of the embedded part 200 exposed in the precast component provides an interface for the subsequent anchoring of the standardized operating platform 100, reducing the installation difficulty of the operating platform.
[0038] By pre-embedding some embedded parts 200 in the precast components, an interface for receiving and installing the standardized operating platform 100 is reserved (i.e., the closed end of the embedded part 200 exposed on the precast component). This avoids structural damage to the precast components caused by drilling holes on-site to install the standardized operating platform 100. It also eliminates the need to erect a long, overhead platform from the opening. The installation and erection process of the external standardized operating platform 100 of this utility model is simple and easy to operate. It provides an overhead working platform for operators, avoiding overhead operations and increasing the safety factor of the installation work. Furthermore, the external standardized operating platform 100 can be standardized to a universal size, is easy to install, and can be recycled and reused, reducing construction costs and improving installation efficiency.
[0039] like Figures 1 to 4As shown, the standardized operating platform 100 includes a standardized external platform 10, which comprises a rectangular platform frame 11 and two load-bearing components 12 symmetrically spaced at the bottom of the frame. Each load-bearing component 12 includes a first column 120, a second column 121, a crossbar 122, and a first diagonal brace 123. The second column 121, the first diagonal brace 123, and the bottom surface of the rectangular platform frame 11 together form a triangular support system. The first column 120 is vertically arranged at the bottom of the rectangular platform frame 11. The free end of the first column 120 serves as the anchoring end of the standardized operating platform 100 at the edge of the platform; the second column 121 is parallel to the first column 120 and is vertically arranged at the bottom of the rectangular platform frame 11, and the distance from the edge of the rectangular platform frame 11 is the length of the crossbar 122; the crossbar 122 is parallel to the rectangular platform frame 11 and is vertically arranged on the side of the second column 121 near the first column 120; the first diagonal brace 123 is arranged between the rectangular platform frame 11 and the second column 121.
[0040] That's understandable, please refer to it. Figure 3 and Figure 7 The dimensions of the first column 120 are adapted to the dimensions of the closed end of the embedded part 200 exposed in the prefabricated component, thereby supporting the insertion of the free end of the first column 120 into the closed end of the embedded part 200 exposed in the prefabricated component.
[0041] By designing the standardized external platform 10 to include a triangular support system, the overall rigidity and stability of the standardized external platform 10 are effectively improved, avoiding problems such as bending, torsion, or lateral displacement of the platform.
[0042] For a better option, please refer to the following. Figure 3 Each load-bearing component 12 further includes a second diagonal brace 124, disposed between the first diagonal brace 123, the rectangular platform frame, and the second column 121. By further setting the second diagonal brace 124 as an oblique support on the basis of the first diagonal brace 123, it forms more triangular closed loops with the rectangular platform frame, the first diagonal brace 123, and the second column 121, making the load-bearing component 12 more stable as a whole. This effectively suppresses the deformation of the formed standardized external platform 10, improves the overall rigidity and stability, distributes the load, and enhances the load-bearing capacity.
[0043] For further details, please refer to... Figure 6 The rectangular platform frame 11 includes a rectangular platform frame 110 and a steel plate 111 disposed on the surface of the rectangular platform frame 110.
[0044] Preferably, the standardized external platform 10 further includes: a number of secondary beams 13, which are arranged between the two second columns 121 and between the rectangular platform frame 110, to collect the local loads that the main beams (the structures that serve as the main beams in the standardized external platform 10 include the rectangular platform frame 110 and the second columns 121) cannot directly bear, and evenly distribute them to the corresponding main beams, so as to reduce the local pressure on the main beams and make the load transfer more uniform and efficient.
[0045] For further details, please refer to... Figure 1 and Figure 5 The standardized operating platform 100 further includes a protective component 30 disposed on the standardized external platform 10. The protective component 30 includes four longitudinal protective railings 31, three transverse protective railings 32, a dense mesh net 33, and four protective uprights 34. The four longitudinal protective railings 31, the three transverse protective railings 32, and the dense mesh net 33 together constitute the main body of the protective fence. The four protective uprights 34 are disposed on the outside of the main body of the protective fence and are fixed parallel to the corresponding longitudinal protective railings 31. All four protective uprights 34 are vertically fixed on the standardized external platform 10.
[0046] Specifically, four protective posts 34 are arranged on the outside of the main body of the protective fence and kept parallel to each longitudinal protective railing 31. The protective posts 34 are reliably connected and fixed to the longitudinal protective railings 31 through connections such as welding, bolting, or fastener fixing. The main functions of the protective posts 34 include: 1) providing stable vertical support and structural anchoring points for the main body of the protective fence; 2) enhancing the overall anti-overturning and anti-deformation capabilities of the main body of the protective fence; 3) serving as installation connectors for connecting to the standardized external platform, enabling the main body of the protective fence to be quickly and safely installed on the standardized external platform, improving construction efficiency and standardization.
[0047] Preferably, the standardized operating platform 100 further includes a plurality of lifting rings 400, which are distributed along the edges of the upper surface of the rectangular platform frame 11 to facilitate the hoisting of the standardized operating platform 100. In this embodiment, there are six lifting rings 400, four of which are welded to the edges of the four corners of the rectangular platform frame 11, thereby ensuring the balance and stability of the standardized external platform during hoisting, facilitating the movement of the standardized external platform while ensuring construction safety.
[0048] In this embodiment, the secondary beams, columns, and diagonal braces of the standardized external platform are all made of L50*4 angle steel; the lifting rings are made of φ20 steel bars; the longitudinal and transverse guardrails and uprights of the protective components are all made of 20*20mm square steel with a height of 1800mm; the steel plate on the surface of the rectangular platform frame is a 3mm thick patterned steel plate. The current manufacturing parameters for each component are to produce the standardized operating platform with universal dimensions for reuse in different projects. In practice, further customization can be carried out according to the actual site conditions in different projects.
[0049] In this embodiment, please refer to Figures 7 to 10 The embedded part 200 is preferably a U-shaped embedded part. It can be understood that the embedded part mentioned here includes, but is not limited to, a U-shaped embedded part, and can also be an elongated elliptical embedded part or a convex polygonal embedded part. As long as the embedded part has a closed end, after the embedded part is embedded in the prefabricated component, the closed end of the embedded part exposed in the prefabricated component can be used as an interface for receiving the anchoring end of the standardized operation platform 100 (the two are combined in a similar way to a pin).
[0050] Preferably, the embedded part is in a bent state, and the bent section of the embedded part is located within the precast component. By placing the bent section of the embedded part within the precast component, the anchoring bond between the embedded part and the precast component is increased. Specifically, during the concrete curing process, the bent portion of the embedded part can mechanically interlock with the concrete. When the concrete hardens, it envelops the various bent parts of the embedded part, which act like "claws" embedded in the concrete, increasing the friction and mechanical holding force between the embedded part and the concrete, further improving the reliability of the anchoring.
[0051] It is understood that the above examples are merely examples listed to better understand the technical solutions of the embodiments of this application, and are not intended to be the only limitation on the embodiments.
[0052] Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by this application.
[0053] To better understand the plug-in standardized operating platform applicable to the PCTF system of the present invention, please refer to [link / reference]. Figure 3 The following explanation uses precast components as outer leaf wall panels as an example to illustrate the process of applying the externally mounted standardized operation platform in construction:
[0054] First, the construction party provides the embedded part positioning and operating platform dimensions based on the installation location of the tower crane attached to the wall. The prefabrication plant embeds the embedded parts in the outer leaf wall panel according to the embedded part positioning provided by the construction unit. The prefabrication plant manufactures the external prefabricated operating platform according to the dimensions provided by the construction unit.
[0055] Next, using a tower crane, the anchoring end of the externally mounted standardized operating platform is precisely inserted into the closed end of the pre-embedded exposed part on the outer leaf wall panel to achieve the installation of the externally mounted standardized operating platform.
[0056] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Therefore, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model also intends to include these modifications and variations.
