[0001] The present invention belongs to the technical field of assembled building systems, and in particular relates to an assembled edge component and a connection method. Background Art

[0002] In the existing construction method, the edge components of the shear wall are mostly cast-in-place, and the connection details are complicated. The connection between the cast-in-place edge components and the assembled prefabricated components requires careful design and construction. Due to the high construction precision requirements, the installation accuracy of the prefabricated components and the construction quality of the cast-in-place parts directly affect the performance of the overall structure, so they need to be strictly controlled.

[0003] The edge components of cast-in-place need to be reinforced, supported and poured with concrete at the construction site, which results in a large number of workers on site. Since many types of work are involved, coordination and communication are more difficult. In addition, human resource management is difficult, construction efficiency is low, and improper allocation of materials and equipment will also increase safety risks, thus affecting project progress and increasing construction costs.

[0004] Therefore, the present application proposes an assembled edge component and a connection method to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the construction efficiency of the edge components in the form of cast-in-place is low in the current construction process, which affects the progress of the project and increases the cost of construction. A brief overview of the present invention is given below to provide a basic understanding of certain aspects of the present invention. It should be understood that this overview is not an exhaustive overview of the present invention. It is not intended to identify the key or important parts of the present invention, nor is it intended to limit the scope of the present invention.

[0006] The technical solution of the present invention:

[0007] Solution 1: An assembled edge member, including an assembled edge member and beam reinforcement, the side wall of the assembled edge member is connected with the beam reinforcement, the assembled edge member includes vertical steel bars, edge member stirrups and a concrete entity, the concrete entity is provided with vertical steel bars and edge member stirrups, and the vertical steel bars are connected with the edge member stirrups.

[0008] Furthermore, a plurality of beam reinforcement holes are processed on the side wall of the concrete entity, and the beam reinforcement is connected to the concrete entity through the beam reinforcement holes. A second grouting hole and a second exhaust hole are processed on the concrete entity, and the second grouting hole and the second exhaust hole are connected to the beam reinforcement holes.

[0009] Furthermore, a plurality of ground reinforcement reserved holes are provided at the bottom of the concrete entity, and the ground reinforcement is connected to the concrete entity through the ground reinforcement reserved holes. A first grouting hole and a first exhaust hole are processed on the lower half of the concrete entity, and the first exhaust hole is arranged above the first grouting hole. The first exhaust hole and the first grouting hole are connected to the ground reinforcement reserved holes.

[0010] Furthermore, a staggered platform is arranged on the upper end surface of the concrete entity.

[0011] Furthermore, a reserved connecting bar is arranged on the concrete entity, one end of the reserved connecting bar is connected to the vertical steel bar in the concrete entity, and the other end of the reserved connecting bar passes through the concrete entity and is arranged on the outside of the concrete entity.

[0012] Solution 2: A method for connecting a prefabricated edge component, which is implemented based on the prefabricated edge component described in Solution 1, and comprises the following steps:

[0013] Step 1: Tie and connect the vertical steel bars with the edge member stirrups to form a steel skeleton of the assembled edge member, place the steel skeleton in the assembled edge member template, embed multiple sleeves or core molds in the lower half of the concrete entity to form a ground reinforcement reserved hole, connect the first grouting hole at the lower part of the sleeve or core mold, and connect the first exhaust hole at the upper part, embed the sleeve or core mold in the side wall of the assembled edge member to form a beam reinforcement reserved hole, and connect the second grouting hole and the second exhaust hole at an appropriate position, set supporting embedded parts and hoisting embedded parts, pour concrete, vibrate and maintain, and complete the processing of the assembled edge member;

[0014] Step 2: transport the assembled edge component to the construction site, adjust the position and verticality of the lower ground reinforcement, hoist the assembled edge component above the lower ground reinforcement, ensure that the ground reinforcement enters the reserved hole for the ground reinforcement, adjust the elevation and verticality of the assembled edge component, and set up support, inject grouting material through the first grouting hole, wait for the grouting material to overflow from the first exhaust hole, and complete the connection between the ground reinforcement and the concrete entity;

[0015] Step 3: Insert the beam reinforcement into the reserved hole for the beam reinforcement, inject the grouting material through the second grouting hole, and wait for the grouting material to overflow from the second exhaust hole to complete the connection between the beam reinforcement and the concrete entity.

[0016] The present invention has the following beneficial effects:

[0017] 1. The prefabricated edge component of the present invention adopts a variety of component forms. The prefabricated edge component can be made into a variety of shapes such as a straight line and an L shape to meet different architectural design requirements, provide greater design flexibility and practicality, and can meet various complex requirements; adopt factory production to reduce the time and process of on-site concrete pouring, significantly improve construction efficiency, and the top of the vertical steel bar is arranged through the concrete entity, making the connection between components simpler and faster, shortening the construction period.

[0018] 2. The assembled edge component of the present invention ensures a tight connection between components through the corresponding design of the protruding vertical steel bars on the top and the reserved holes for the ground reinforcement at the bottom, thereby enhancing the stability and seismic resistance of the overall structure. In addition, the reserved grouting holes and exhaust holes can effectively ensure the density and uniformity of the grouting in the connecting holes, thereby improving the connection strength and durability.

[0019] 3. Through the pre-embedded beam reinforcement reserved holes and grouting holes, the construction process can achieve rapid connection, reducing the complexity and working hours of on-site steel bar binding, thereby improving construction efficiency. Through grouting technology, the grouting material can fully fill the beam reinforcement reserved holes to ensure the tight connection between the beam reinforcement and the concrete entity. This grouting connection method can effectively eliminate the gaps and unevenness problems in the traditional binding method, and enhance the integrity and tensile strength of the structure. The design of the reserved holes optimizes the bonding force between the beam reinforcement and the concrete, so that the beam reinforcement can give full play to its force performance, thereby improving the stability and seismic performance of the entire structure. The pre-embedded beam reinforcement reserved holes and grouting system can reduce the risks of manual intervention and steel bar binding in on-site construction, avoid quality risks caused by improper operation of workers, and thus improve construction safety and reliability. This pre-embedded channel and grouting connection technology enables the prefabricated edge components to complete part of the steel bar connection when they are prefabricated in the factory, and only simple hoisting and grouting are required on site, which greatly shortens the construction period and improves the construction adaptability of prefabricated components. The design of beam reinforcement and beam reinforcement reserved holes can flexibly adapt to the conditions of different construction sites, especially in complex construction environments, which can effectively simplify the construction process and reduce the difficulty of on-site construction. The use of grouting to connect beam reinforcement can not only ensure the accuracy and quality of the connection, but also effectively control the rework costs caused by on-site construction errors, which helps to optimize the project budget and improve economic benefits.
