Description

Technical Field

[0001] The invention relates to a non-reinforced connection device for prefabricated components. Background Art

[0002] At present, my country's construction industry has entered a critical period of high-quality industrial development in the new era. Prefabricated construction technology, with its unique advantages, has become one of the core driving forces for the transformation and upgrading of the construction industry. In the prefabricated building system, the connection technology of prefabricated components undoubtedly occupies a pivotal position. It is like a bond, which is not only directly related to the safety and stability of the building structure, but also has a decisive impact on construction efficiency.

[0003] Despite numerous efforts to advance prefabricated construction, the implementation of prefabricated construction continues to expose several pressing issues. The hoisting and connection of precast concrete components (hereinafter referred to as precast components) is an essential and core step in the construction process, but traditional methods present numerous drawbacks. Currently, the conventional method for connecting precast components involves pre-retaining protruding rebar on the precast components. Once the precast components are hoisted into place according to design requirements, they are connected at the joints using cast-in-place concrete, forming a cohesive whole. However, this method has significant drawbacks. Because the protruding rebar between precast components is concentrated at the joints, the rebar density in the joints is dense, making it extremely difficult to avoid unnecessary movement between the rebar. This not only requires highly skilled and experienced construction personnel, but also easily leads to improper rebar placement, compromising the structural performance.

[0004] At the same time, due to the difficulty in avoiding steel bars, a lot of time is required for adjustment and alignment during the hoisting process, which greatly prolongs the occupation period of the hoisting equipment. This not only increases construction costs, but also makes it difficult to control the construction progress, which can easily lead to uncontrollable construction quality and construction period. Once the construction period is delayed, it will directly affect the performance of the project construction, causing huge economic losses to the construction unit, the construction unit and related stakeholders. What is more serious is that if the steel bar layout is unreasonable or the node connection quality is poor, it may cause stress concentration and local damage to the main structure when it is under load, thereby burying serious safety hazards in the main structure and posing a potential threat to people's lives and property. Therefore, there is an urgent need to develop a more scientific, efficient, safe and reliable prefabricated component hoisting and connection technology to promote the healthy development of the prefabricated building industry. Summary of the Invention

[0009] In this embodiment, the top surface of the lower supporting corbel and the bottom surface of the upper supporting corbel are corresponding planes.

[0010] In this embodiment, the first anchor rod and the second anchor rod have the same structure and both include a steel bar and an anchor plate, and the anchor plate is fixed to the end of the steel bar.

[0011] In this embodiment, the second through hole, the third through hole, the fifth through hole and the sixth through hole are all waist-shaped holes.

[0012] In this embodiment, the connecting member includes a first end plate, a second end plate, a connecting rod and a bolt assembly, the first end plate and the second end plate are arranged in parallel, the first end plate and the second end plate are fixed into a whole by multiple connecting rods, the first end plate is provided with a plurality of seventh through holes corresponding to the first through holes, and the second end plate is provided with a plurality of eighth through holes corresponding to the fourth through holes.

[0013] Due to the above structure, the device has the following advantages:

[0014] 1. The first embedded parts, the second embedded parts, the connecting parts and the bolt assembly are a prefabricated component connection method that does not rely on exposed steel bars or welding. The core of the method is that steel embedded parts are reserved in the factory for the prefabricated components, which are hoisted into place on site and mechanically locked in the node area by bolt assemblies and connecting parts. After the template is set in the node area, concrete is poured to form an overall structure to achieve a reliable connection between the prefabricated components. This is a prefabricated component non-reinforced connection device that can effectively improve installation efficiency and quality. This device prefabricated the first embedded parts and the second embedded parts with reinforced concrete in the processing plant to form the first prefabricated component and the second prefabricated component respectively. After hoisting and self-positioning on site, they are fastened together by connecting parts and bolt assemblies to form a reliable prefabricated structure. It can reduce construction measures, reduce construction difficulty and improve project quality.

[0015] 2. Both the first and second prefabricated components adopt a non-reinforced design. Only the first embedded parts and the second embedded parts are embedded in the prefabricated components to achieve connection with adjacent components. This structure can avoid the interference phenomenon caused by the reinforcement design during lifting.

[0016] 3. The first and second embedded parts, as well as the connectors, are all manufactured in a steel structure fabrication plant through cutting, drilling, welding, and other production processes. They offer low cost, reliable structure, and convenient embedding. Anchor rods consisting of steel bars and anchor plates are welded to the backs of the first and second embedded parts, ensuring a secure connection between the embedded parts and the prefabricated components. The fronts of the first and second embedded parts utilize a fully layered connection structure with a socket-and-spigot lower portion, a support center, and a pull-and-joint upper portion. This utilizes simple and efficient bolt connections to create a safe and reliable overall structure.

[0017] 4. The second through hole, the third through hole, the fifth through hole and the sixth through hole of this device are all waist-shaped holes, which improve the hoisting fault tolerance and on-site construction efficiency.

[0018] In summary, this device simplifies the connection structure of prefabricated components by processing and manufacturing parts in the factory and adopting a non-reinforced connection device. It only needs to use bolt mechanical connection, which makes on-site operation simple and efficient, realizes the standardized split design of prefabricated components and rapid on-site installation and connection, realizes the installation of prefabricated components with little or no support, reduces on-site construction measures, realizes the rapid unhooking of prefabricated components, reduces the long-term occupation of lifting equipment, realizes the simplified processing of connection nodes between various complex prefabricated components, and improves construction feasibility. Therefore, this device can not only avoid the continuous hoisting time due to steel bar interference, but also reduce the construction processes such as component positioning, fixing, and supporting, thereby significantly improving the constructability of the project, saving construction time, and at the same time being conducive to the effective control of engineering construction costs and quality.
