Description
Technical Field
[0001] The utility model relates to the technical field of foundation pit safety construction, in particular to a reinforcement positioning device suitable for assembled foundation pit pile heads. Background Art
[0002] With the rapid development of my country's economy and urbanization, densely populated urban areas have also become areas of land shortage. High-rise buildings, municipal and pipeline projects have gradually expanded to underground spaces, and deep and large foundation pits have continued to appear. How to improve construction efficiency, reduce construction costs and reduce carbon emissions under the premise of safe construction has become an important issue to consider in architectural design. Prefabricated foundation pits have the advantages of safety, high efficiency, low carbon and environmental protection. However, prefabricated foundation pits have high requirements for refined installation and positioning during construction.
[0003] During the construction of prefabricated foundation pile foundation, the refined control of the angle and spacing of the pile head extending into the top plate cap steel bars is one of the difficult problems faced by the on-site construction of prefabricated foundation pits. The angle and spacing deviation of the steel bars is often an important factor affecting the refined construction of prefabricated foundation pit pile foundations, which can easily lead to a long construction period, and the construction quality and the bearing capacity of the foundation pit pile foundation do not meet the requirements of the specifications. In severe cases, it can easily cause a large settlement of the foundation pit that exceeds the critical value required by the specifications.
[0004] Common ways of connecting pile foundation and top plate cap include directly penetrating the top of the pile into the upper structure or penetrating the top of the pile into the upper structure through anchor iron or steel bars to achieve rigid connection. Commonly used mechanical driving or setting the pile core reinforced concrete connection based on experience at the top of the pile will inevitably result in the angle and spacing of the steel bars extending into the top plate cap not meeting the design requirements, affecting the construction quality.
[0005] For example, in the patent application with publication number CN216729277U in the prior art, in order to adjust the angle and bending height of the steel bars, it is necessary to replace support steels of different lengths to adjust the height, which will consume a lot of manpower to disassemble the device. Therefore, a steel bar positioning device suitable for assembled foundation pit pile heads is needed to solve the above technical problems. Utility Model Content
