Description

Technical Field

[0001] This utility model relates to the field of precast slab installation technology, and in particular to a multi-angle installation structure for precast concrete components. Background Technology

[0002] Precast concrete components are concrete products prefabricated in factories through standardized processes. They encompass various types, including wall panels, beams, columns, and floor slabs, and can be directly transported to the construction site for assembly. They are a core component of prefabricated buildings. With rapid socio-economic development and increasingly fierce competition in the construction market, construction companies are pursuing higher project quality while also demanding stricter requirements for shorter construction periods, cost control, and environmental protection. Prefabricated structures, with their advantages of factory production, high on-site assembly efficiency, less construction waste, and lower construction pollution, effectively meet the core needs of construction companies and show promising application prospects in various construction projects. In the prefabrication and installation of concrete wall panels, multi-angle installation adjustment structures can assist in the angle adjustment and installation of precast components, facilitating rapid and high-quality assembly on the construction site and improving construction efficiency and quality.

[0003] In existing technologies, precast concrete wall panels are typically installed using a simple monolithic concrete pour. Under significant loads or shear forces, these panels are prone to breakage due to insufficient rigidity. The corners of the precast wall panels are also susceptible to impact damage. The overall load-bearing capacity of the wall is insufficient, and the adjustment range of the adjustment structure is limited. When the wall is laid at a large angle due to uneven foundation, it cannot achieve wide-range, precise angle compensation, requiring additional shims and pads for raising or leveling. This not only increases the construction process but also increases the risk of poor compatibility between the auxiliary components and the adjustment structure, leading to insufficient wall angle flatness and making it difficult to guarantee the overall accuracy of the wall panel installation, ultimately affecting the construction progress. Therefore, we propose a multi-angle installation structure for precast concrete components to solve these problems. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Please see Figures 1-6 The precast concrete component uses a multi-angle installation structure, including a precast slab body 1 and a keel-type reinforcing steel bar 2 embedded inside the precast slab body 1.

By rotating different installation angle adjustment pieces 6, the slab body 1 can be threadedly raised or lowered within different vertical support brackets 5, thus allowing for tilt angle adjustment during vertical laying, facilitating subsequent pouring and installation. When the precast slab body 1 is laid flat, the angle adjustment piece 6 can be installed in the flat support bracket 4. Depending on the required tilt angle, the angle adjustment piece 6 can be rotated and threaded up and down in different flat support brackets 4, which facilitates fine-tuning of the angle during the laying process. It is suitable for fine-tuning the angle when the foundation is uneven and there is a large tilt. After the installation is completed, it can be fixed by pouring concrete to fix the support components and enhance its installation and laying strength.

The square support ends 602 can be used for rotation clamping with wrenches or pliers, and the arc-shaped support plates 603 play a supporting role, which facilitates stable laying and placement at different angles and provides stable load-bearing. The two ends of the integrated tensile reinforcement 8 are welded and fixed between the two reinforcing frames 3 respectively, resulting in high installation strength. The integrated tensile reinforcement 8 is L-shaped and fits tightly to the corner of the precast slab body 1, resulting in high installation load-bearing strength and good adaptability. The integrated tensile reinforcement 8 includes a mounting plate 801, mounting holes 802, and bolted fixing ends 803. The mounting holes 802 are formed on the mounting plate 801, allowing the mounting plate 801 to be fitted onto both ends of the vertical reinforcement 202 through the mounting holes 802. Subsequently, the vertical reinforcement 202 and the mounting plate 801 are welded together as a whole.
