Abstract
Description
Technical Field
[0001] This utility model relates to the field of deformation early warning technology, specifically a deformation early warning device for large-diameter cylindrical steel formwork. Background Technology
[0002] In recent years, with the rapid development of the construction industry, large-diameter circular concrete columns have become increasingly common in bridges and buildings, typically using steel formwork for in-situ casting. To ensure the quality and safety of construction, monitoring and early warning of steel formwork deformation is essential. Currently, during the casting of circular columns, construction units usually assign dedicated personnel to monitor the deformation of the steel formwork, which is labor-intensive. Furthermore, since casting is generally scheduled at night, the accuracy of monitoring is not high, posing certain risks. Utility Model Content
[0003] In view of the above-mentioned prior art, this utility model proposes a deformation early warning device for large-diameter cylindrical steel formwork.
[0004] This utility model provides a deformation early warning device for a large-diameter cylindrical steel formwork, which includes multiple early warning units. The multiple early warning units are evenly distributed on the outside of the large-diameter cylindrical steel formwork. The upper and lower early warning units form a pair. One early warning unit is used to emit a row of lasers, and the other early warning unit is used to receive the lasers and record the position.
[0005] Preferably, the early warning unit includes a housing, with a laser receiving module disposed on the top of the housing and a laser emitting module disposed on the bottom of the housing.
[0006] Preferably, magnetic strips are provided on both sides of the housing for adhering to large-diameter cylindrical steel templates.
[0007] Preferably, the early warning unit is equipped with a main control module, and the main control module is equipped with a network module and a buzzer.
[0008] Preferably, the front of the warning unit is provided with an LCD screen.
[0009] Preferably, the warning unit has an input keyboard on its front side.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The deformation early warning device for large-diameter cylindrical steel formwork provided by this utility model can monitor the deformation of the steel formwork in real time, reduce the manual labor required for on-site monitoring of steel formwork deformation, improve the accuracy of monitoring, and reduce construction risks.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] Example: Figures 1-3 The device shown is a deformation early warning device for a large-diameter cylindrical steel formwork, comprising multiple early warning units 1. Each early warning unit 1 includes a housing, with a laser receiving module 2 at the top and a laser emitting module 3 at the bottom. Magnetic adhesive strips 4 are provided on both sides of the housing for adhering to the large-diameter cylindrical steel formwork. Each early warning unit includes a main control module, employing a PLC control system, and is equipped with a network module and a buzzer. The front of each early warning unit features an LCD screen 5 and an input keyboard 6, used to display the system settings output interface and to input and adjust the device's system settings, respectively.
[0017] In practical applications, multiple early warning units 1 are evenly distributed on the outside of the large-diameter cylindrical steel formwork. The upper and lower early warning units 1 form a pair. The upper early warning unit 1 is used to emit a row of lasers, and the lower early warning unit 1 is used to receive the lasers and record the position. During the pouring process, if the steel formwork deforms, the early warning unit 1 that receives the lasers will move. If the movement exceeds the set value, the buzzer will sound an alarm and send a warning to the networked devices.
[0018] The deformation early warning device in this embodiment can monitor the deformation of steel formwork in real time, reduce the need for manual on-site monitoring of steel formwork deformation, improve the accuracy of monitoring, and reduce construction risks.
[0019] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent solutions made using the contents of this utility model specification, whether directly or indirectly applied to other related technical fields, are also within the patent protection scope of this utility model.
