Description
Technical Field
[0001] The present invention relates to the technical field of building construction, and in particular to a rapid leveling detection device and a leveling method for assembled composite panels. Background Art
[0002] As a key development direction in modern building industrialization, prefabricated construction has achieved remarkable success worldwide. Developed countries, through decades of technological accumulation, have established standardized design systems, factory-based production models, and prefabricated construction processes, demonstrating significant advantages in building quality, efficiency, energy conservation, and environmental protection. In recent years, driven by policies, my country's prefabricated construction industry has rapidly developed, but its practical application still faces numerous technical challenges. Due to issues such as insufficient machining precision of prefabricated components and immature on-site installation techniques, improvements in construction efficiency have been limited, and some projects have even experienced extended construction periods.
[0003] During the implementation of prefabricated buildings, the quality of the installation of composite slabs directly affects the overall performance of the building. Traditional construction methods rely on manual leveling and measurement, which are cumbersome to operate and difficult to control precision. Especially during the concrete pouring stage, the flatness of the bottom of the composite slab is difficult to monitor in real time, and elevation deviations are prone to exceeding the limit. Later rectification not only increases construction costs but may also affect structural safety. Existing leveling technologies mostly use simple supports combined with manual measurement, lacking systematic detection methods, and are unable to meet the construction accuracy requirements of prefabricated buildings. How to achieve rapid and accurate leveling while ensuring construction efficiency has become a key link in promoting the development of prefabricated building technology. Summary of the Invention
[0004] The present invention aims to solve the above-mentioned problem, thereby providing a prefabricated composite plate rapid leveling detection device and leveling method capable of monitoring the flatness of the bottom of the composite plate.
[0005] The present invention solves the above problems by adopting the following technical solutions: A rapid leveling detection device for assembled composite plates comprises a fixed frame, a connecting piece is detachably provided at the top center of the fixed frame, a counterweight power supply module located in the fixed frame is connected to the bottom of the connecting piece, a lifting connection module is provided at the top of the connecting piece, a laser rangefinder is provided at the top of the lifting connection module, and an automatic leveling receiver is provided in the middle of the lifting connection module and is controllably connected to the lifting connection module.
[0006] The leveling method using the assembled composite plate rapid leveling detection device comprises the following steps: S1: When pouring concrete on the upper part of the composite slab, place a laser leveler in the space under the slab to release infrared rays as a reference for controlling the flatness of the slab.
[0007] S2: Place the detection devices one by one at the four corners under the board. After the detection devices are placed stably, under the action of the counterweight power supply module, the laser rangefinder is vertically upward and opposite to the bottom of the laminated board.
[0008] S3: The automatic leveling receiver receives the signal from the laser leveler and automatically levels.
[0009] S4: During the leveling process, the lifting connection module is controlled to move longitudinally, and the laser rangefinder is sent to the specified height to measure the bottom elevation of the board in real time.
[0010] S5: The worker holds the jack and performs secondary support according to the measured value.
[0011] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: The present invention integrates laser ranging and automatic leveling technology to construct a construction quality control system for prefabricated composite slabs. The collaborative working mode of the laser rangefinder and the automatic leveling receiver solves the pain points of low efficiency and poor accuracy of traditional manual measurement; the embedded design of the counterweight power supply module ensures the stability of the detection device and overcomes the limitation of inconvenient power access at the construction site; the longitudinal adjustment function of the lifting connection module realizes dynamic monitoring of the elevation of the bottom of the slab, and forms a closed-loop control system with an external laser sweeper, which effectively prevents the elevation deviation problem during the concrete pouring stage; the device changes the measurement benchmark from manual judgment to automatic instrument recognition, reduces the human intervention link through mechatronic design, and improves the leveling accuracy while maintaining construction efficiency.
[0012] Preferably, a further technical solution of the present invention is: Furthermore, the fixed frame includes a conical frame body, and a placement tray is provided on the top of the conical frame body. The conical frame body and the placement tray are combined to form a stable support structure.

[0015] Furthermore, a clipping groove is provided on the fixing rod, and a clamp used in conjunction with the clipping groove is provided on the back side of the automatic leveling receiver. The cooperating structure of the clipping groove and the clamp provides a quick positioning interface for the automatic leveling receiver. Its asymmetric clipping method prevents the instrument from being installed misplaced, while retaining the necessary adjustment margin to adapt to the installation of different models of equipment.
