Description

Technical Field

[0001] This utility model belongs to the technical field of prefabricated building system, specifically a prefabricated edge component. Background Technology

[0002] In existing construction methods, the connection between cast-in-place edge components and prefabricated components requires meticulous design and construction. Due to the high precision requirements, the installation accuracy of prefabricated components and the construction quality of the cast-in-place portion directly affect the overall structural performance, thus necessitating strict control. Using cast-in-place edge components requires on-site reinforcement binding, formwork erection, and concrete pouring, resulting in a large on-site labor load and involving multiple trades, increasing the difficulty of coordination and communication. Improper allocation of materials and equipment can also increase safety risks, thereby affecting project progress and driving up costs.

[0003] Therefore, this application proposes an assembled edge component to solve the above problems. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0018] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections (i.e., non-detachable connections) include, but are not limited to, conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include, but are not limited to, conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Example 1, combined with Figures 1-3 This embodiment describes a prefabricated edge component, including a prefabricated edge component 1 and a double-sided composite connecting beam 9. The prefabricated edge component 1 and the double-sided composite connecting beam 9 are connected by a web reinforcement 4 and a main beam reinforcement 5. The web reinforcement 4 and the main beam reinforcement 5 are connected to the side wall of the prefabricated edge component 1. The double-sided composite connecting beam 9 includes an outer beam surface 11 and an inner beam surface 12. The outer beam surface 11 and the inner beam surface 12 are connected by beam stirrups 10. A cavity is formed between the outer beam surface 11 and the inner beam surface 12 to accommodate the web reinforcement 4 and the main beam reinforcement 5. After the components are installed, the cavity is filled with concrete.

[0021] Before construction, the prefabricated edge component 1 is manufactured in the factory and transported to the construction site. Vertical steel bars 2 are installed inside the prefabricated edge component 1. One end of the vertical steel bars 2 passes through the upper surface of the prefabricated edge component 1 and is arranged at the top of the prefabricated edge component 1. According to construction needs, distribution steel bars 3 can also be installed inside the prefabricated edge component 1. One end of the distribution steel bars 3 passes through the side wall of the prefabricated edge component 1 and is arranged on the outside of the prefabricated edge component 1. The installation of vertical steel bars 2 and distribution steel bars 3 can make the connection between the top and side wall of the prefabricated edge component 1 and other components easier and faster, and shorten the construction cycle.

[0022] The upper surface of the prefabricated edge component 1 is machined with a staggered platform 8. The staggered platform 8 can eliminate the need for the formwork at the floor slab position during the construction of the prefabricated edge component 1, saving turnover materials and shortening the construction time.

[0023] Similar to the prefabricated edge component 1, the double-sided composite connecting beam 9 is also prefabricated in the factory and then transported to the construction site. Multiple beam stirrups 10 are connected to the inner wall of the outer beam surface 11 and the inner wall of the inner beam surface 12 of the double-sided composite connecting beam 9 to form the double-sided composite connecting beam 9.

[0024] The prefabricated assembled edge component 1 and the double-sided composite connecting beam 9 are transported to the construction site. After installation, the web reinforcement 4 is first inserted through the cavity of the double-sided composite connecting beam 9 into the web reinforcement hole 13 of the assembled edge component 1. Then, the main beam reinforcement 5 is inserted through the cavity of the double-sided composite connecting beam 9 into the main beam reinforcement hole 14 of the assembled edge component 1. Subsequently, grout is injected into the grouting hole 6 on the assembled edge component 1 until grout is continuously discharged from the vent hole 7, proving that the web reinforcement 4 and the main beam reinforcement 5 are connected to the assembled edge component 1 as a whole through the grout. Finally, concrete is poured into the cavity formed between the outer beam surface 11 and the inner beam surface 12, connecting the double-sided composite connecting beam 9 and the assembled edge component 1 through cast-in-place concrete. The web reinforcement 4 and the main beam reinforcement 5 are connected to the double-sided composite connecting beam 9 and the assembled edge component 1 through the bonding of concrete and grout.

[0025] This embodiment is merely an exemplary illustration of this application and does not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of this application, they are all within the scope of protection of this application.
