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 edge members of shear walls are mostly cast-in-place, resulting in complex connection details. The connection between cast-in-place edge members and precast components requires meticulous design and construction. Due to the high precision requirements, the installation accuracy of precast components and the construction quality of the cast-in-place portion directly affect the overall structural performance, thus requiring strict control.
[0003] The use of cast-in-place edge components requires on-site reinforcement, formwork, and concrete pouring, resulting in a large on-site labor demand. The involvement of multiple trades also increases the difficulty of coordination and communication. Furthermore, challenges in human resource management, low construction efficiency, and improper allocation of materials and equipment can increase safety risks, thereby affecting project progress and raising construction costs.
[0004] Therefore, this application proposes an assembled edge component to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problems of low construction efficiency, delayed project progress, and increased construction costs associated with cast-in-place edge components in current building construction processes. A brief overview of this invention is provided below to offer a basic understanding of certain aspects of it. It should be understood that this overview is not an exhaustive summary of the invention. It is not intended to identify key or essential parts of the invention, nor is it intended to limit its scope.
[0006] The technical solution of this utility model:
[0007] A prefabricated edge member includes a prefabricated edge member and beam reinforcement. The beam reinforcement is connected to the side wall of the prefabricated edge member. The prefabricated edge member includes vertical reinforcement, edge member stirrups and a concrete core. The vertical reinforcement and edge member stirrups are provided inside the concrete core, and the vertical reinforcement is connected to the edge member stirrups.
[0008] Furthermore, the concrete entity has multiple pre-drilled holes for beam reinforcement on its sidewalls. The beam reinforcement is connected to the concrete entity through these pre-drilled holes. The concrete entity also has a second grouting hole and a second venting hole, which are connected to the pre-drilled holes for beam reinforcement.
[0009] Furthermore, the bottom of the concrete entity is provided with multiple reserved holes for ground reinforcement bars, which are connected to the concrete entity through the reserved holes. The lower half of the concrete entity is provided with a first grouting hole and a first venting hole. The first venting hole is arranged above the first grouting hole and is connected to the reserved holes for ground reinforcement bars.
[0010] Furthermore, a staggered platform is provided on the upper surface of the concrete entity.
[0011] Furthermore, the concrete entity is provided with a reserved connecting bar, one end of which is connected to the vertical reinforcing bar inside the concrete entity, and the other end of which passes through the concrete entity and is arranged on the outside of the concrete entity.
[0012] This utility model has the following beneficial effects:
[0013] 1. The prefabricated edge component of this utility model adopts diverse component forms. The prefabricated edge component can be made into various shapes such as straight line and L-shape to adapt to different architectural design needs, providing greater design flexibility and practicality, and can meet various complex requirements. It adopts factory production, reducing the time and procedures of on-site concrete pouring, significantly improving construction efficiency. The vertical steel bars are arranged through the concrete solid at the top, making the connection between components simpler and faster, and shortening the construction period.
[0014] 2. The prefabricated edge component of this utility model ensures a tight connection between components through the corresponding design of the top extended vertical steel bars and the reserved holes of the bottom ground steel bars, which enhances the stability and seismic performance of the overall structure. In addition, the reserved grouting holes and venting holes can effectively ensure the density and uniformity of the grouting in the connection holes, and improve the connection strength and durability.
[0015] 3. By pre-embedding the reinforcing bars in the beams with reserved holes and grouting holes, rapid connection can be achieved during construction, reducing the complexity and time required for on-site rebar tying and thus improving construction efficiency. Grouting technology allows the grout to fully fill the reserved holes in the reinforcing bars, ensuring a tight connection between the reinforcing bars and the concrete structure. This grouting connection method effectively eliminates gaps and unevenness issues inherent in traditional tying methods, enhancing the overall integrity and tensile strength of the structure. The optimized design of the reserved holes improves the bonding force between the reinforcing bars and the concrete, allowing the reinforcing bars to fully utilize their load-bearing capacity, thereby improving the stability and seismic performance of the entire structure. The pre-embedding of the reinforcing bars in the beams with reserved holes and the grouting system reduces on-site manual intervention and the risks associated with rebar tying, avoiding quality hazards caused by improper worker operation, thus improving construction safety and reliability. This pre-embedded hole and grouting connection technology allows for partial rebar connection during the prefabrication of prefabricated edge components in the factory, requiring only simple hoisting and grouting on-site, significantly shortening the construction cycle and improving the construction adaptability of prefabricated components. The design of the beam reinforcement bars and pre-drilled holes allows for flexible adaptation to different construction site conditions. Especially in complex construction environments, it effectively simplifies the construction process and reduces on-site construction difficulties. Using grouting to connect the beam reinforcement bars not only ensures the accuracy and quality of the connection but also effectively controls rework costs caused by on-site construction errors, helping to optimize project budgets and improve economic efficiency.

[0030] Example 1, combined with Figures 1-4 , Figures 9-10This embodiment describes a prefabricated edge component, including a prefabricated edge component 1, beam reinforcement 12, and ground reinforcement 14. The beam reinforcement 12 is connected to the side wall of the prefabricated edge component 1, and the ground reinforcement 14 is connected to the bottom of the prefabricated edge component 1. The prefabricated edge component 1 is connected to the ground through the ground reinforcement 14. The prefabricated edge component 1 includes vertical reinforcement 2, reserved connecting reinforcement 3, edge component stirrups 4, and a concrete body 5. The vertical reinforcement 2, reserved connecting reinforcement 3, and edge component stirrups 4 are provided inside the concrete body 5. One end of the reserved connecting reinforcement 3 passes through the concrete body 5 and is arranged on the outside of the concrete body 5. Multiple vertical reinforcement 2 are connected to the edge component stirrups 4.
[0031] In this embodiment, the prefabricated edge component 1 is a straight-line prefabricated edge component. First, in the factory, according to the shape of the edge component, multiple edge component stirrups 4 are fitted onto the vertical reinforcing bars 2. Each vertical reinforcing bar 2 is then tied or welded to the edge component stirrup 4. Subsequently, as needed, the reserved connecting bars 3 are fixed to the vertical reinforcing bars 2, completing the installation of the internal reinforcing bar skeleton of the prefabricated edge component 1, as shown in the attached figure. Figure 4 As shown;
[0032] Concrete is poured onto the formed internal steel reinforcement skeleton to form concrete entity 5. Concrete entity 5, together with vertical steel reinforcement 2, reserved connecting reinforcement 3 and edge member stirrup 4, forms a straight-line prefabricated edge member 1. The upper end of vertical steel reinforcement 2 passes through concrete entity 5 and is exposed to the outside. One end of reserved connecting reinforcement 3 passes through concrete entity 5 and is exposed to the outside, which facilitates connection with other prefabricated components.
[0033] A staggered platform 11 is set on the upper surface of the concrete entity 5. The purpose of the staggered platform 11 is to eliminate the need for formwork support in the floor slab area and reduce construction procedures.
[0034] Pre-drilled holes 6 for beam reinforcement are reserved on the side wall of concrete entity 5. According to construction requirements, beam reinforcement 12 can be connected to concrete entity 5 through beam reinforcement reserved holes 6. A second grouting hole 9 and a second venting hole 10 are processed on the upper end face of concrete entity 5. The second grouting hole 9 and the second venting hole 10 are connected to beam reinforcement reserved holes 6. The second grouting hole 9 is arranged at the near end of beam reinforcement reserved holes 6, and the second venting hole 10 is arranged at the far end of beam reinforcement reserved holes 6.
[0035] A pre-drilled hole 13 for the ground reinforcement is processed at the bottom of the concrete entity 5. The ground reinforcement 14 is connected to the concrete entity 5 through the pre-drilled hole 13. A first grouting hole 7 and a first vent hole 8 are processed on the concrete entity 5. The first grouting hole 7 is arranged below the first vent hole 8. The first grouting hole 7 and the first vent hole 8 are connected to the pre-drilled hole 13 for the ground reinforcement.
[0036] The prefabricated edge components 1, manufactured in the factory, are transported to the construction site. The reinforcing bars 14 are inserted into the pre-drilled holes 13, and grout is injected into the first grouting hole 7. Once grout continues to flow from the first vent hole 8, the reinforcing bars 14 are fixedly connected to the concrete structure 5. If necessary, the beam reinforcing bars 12 are inserted into the pre-drilled holes 6, and grout is injected into the second grouting hole 9 until grout continues to flow from the second vent hole 10, completing the connection between the beam reinforcing bars 12 and the concrete structure 5.
[0037] Example 2, combined with Figures 5-10 This embodiment describes an L-shaped prefabricated edge component 1. In the factory, a set of vertical reinforcing bars 2 are fabricated and arranged perpendicularly to another set of vertical reinforcing bars 2. Then, each set of vertical reinforcing bars 2 is used as a unit to fit multiple edge component stirrups 4, which are tied or welded to each vertical reinforcing bar 2. The vertical reinforcing bars 2 or the edge component stirrups 4 are fixed with pre-reserved connecting bars 3, forming the reinforcing steel skeleton of the L-shaped prefabricated edge component 1, as shown in the attached diagram. Figure 8 As shown; concrete is poured onto the steel reinforcement cage to form concrete entity 5, as attached. Figure 5 As shown.
[0038] According to the construction requirements, a staggered platform 11 is set on the upper surface of the concrete entity 5. The staggered platform 11 eliminates the need for formwork support in the floor slab area, reducing construction procedures.
[0039] The processing positions of the pre-reserved holes 6 for beam reinforcement and 13 for ground reinforcement on the L-shaped prefabricated edge component 1 are the same as those of the straight-line prefabricated edge component in Example 1. The setting principles of the first grouting hole 7, the first vent hole 8, the second grouting hole 9, and the second vent hole 10 are the same. After processing, it is transported to the construction site for assembly.
[0040] The L-shaped prefabricated edge component 1 and the straight prefabricated edge component 1 are installed in the same way during construction. First, after the ground reinforcement 14 enters the concrete body 5, grout is injected into the first grouting hole 7 until grout is continuously discharged from the first vent hole 8, thus completing the fixed connection between the prefabricated edge component 1 and the ground. The beam reinforcement 12 is inserted into the beam reinforcement reserved hole 6, and grout is injected through the second grouting hole 9 until grout is continuously discharged from the second vent hole 10, thus completing the connection between the beam reinforcement 12 and the concrete body 5.
[0041] Example 3, combined with Figures 1-10 This embodiment describes a method for connecting prefabricated edge components, which includes the following steps:
[0042] Step 1: Tie the vertical steel bars 2 to the edge member stirrups 4 to form the steel reinforcement skeleton of the prefabricated edge member 1. Place the steel reinforcement skeleton in the template of the prefabricated edge member 1. Embed multiple sleeves or core molds in the lower half of the concrete entity 5 to form the ground reinforcement reserved hole 13. Connect the first grouting hole 7 at the bottom of the sleeve or core mold and the first vent hole 8 at the top. Embed sleeves or core molds in the side wall of the prefabricated edge member 1 to form the beam reinforcement reserved hole 6. Connect the second grouting hole 9 and the second vent hole 10 at appropriate positions. Set up the support embedded parts and hoisting embedded parts. Pour, vibrate and cure the concrete to complete the processing of the prefabricated edge member 1.
[0043] Step 2: Transport the prefabricated edge component 1 to the construction site, adjust the position and verticality of the lower ground reinforcement 14, hoist the prefabricated edge component 1 above the lower ground reinforcement 14, ensure that the ground reinforcement 14 enters the ground reinforcement reserved hole 13, adjust the elevation and verticality of the prefabricated edge component 1, and set up support. Inject grouting material through the first grouting hole 7. Wait for the grouting material to overflow from the first vent hole 8 to complete the connection between the ground reinforcement 14 and the concrete entity 5.
[0044] Step 3: Insert the beam reinforcement 12 into the pre-drilled hole 6, and inject grout through the second grouting hole 9. Once the grout overflows from the second vent hole 10, the connection between the beam reinforcement 12 and the concrete body 5 is completed.
[0045] This embodiment is merely an exemplary description of the present utility model 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 the present utility model, they are all within the scope of protection of the present utility model.
