Description

Technical Field

[0001] This utility model relates to the field of building engineering observation technology, specifically a device for observing building settlement. Background Technology

[0002] In the field of building engineering, settlement monitoring is a crucial aspect of ensuring project safety. Whether during construction or after completion and operation, factors such as soil compression, groundwater level changes, and disturbances from surrounding construction can all lead to foundation settlement. If the settlement exceeds the normal range, it poses a potential threat to structural safety. Therefore, regular settlement monitoring to track key indicators such as settlement rate and cumulative settlement is essential for verifying the rationality of foundation design, controlling construction progress and quality, and ensuring the safe use of buildings.

[0003] Currently, there are two main methods for deploying conventional building settlement monitoring markers: drilling and embedding L-shaped markers, and affixing barcode monitoring markers. However, both of these traditional methods have significant limitations in practical applications. For drilling and embedding L-shaped markers, when the building foundation pit is not completely backfilled, it is difficult for observers to approach the monitoring point to take readings, making normal monitoring impossible. Furthermore, when the building surface is made of high-end decorative materials such as marble or ceramic tiles, drilling can damage the surface aesthetics and may also cause structural damage. While affixing barcode monitoring markers avoids the drilling problem, it requires extremely precise measurement angles from the monitoring instruments and necessitates frequent station changes during field observations, resulting in low work efficiency. For example, in a residential community renovation project, using traditional affixed barcodes for monitoring took more than 40 minutes per observation, and the measuring points were easily damaged or obstructed by external factors (such as construction debris or personnel collisions), making it difficult to guarantee data continuity and accuracy. In addition, traditional single-point, single-direction observation mode is prone to data loss when encountering temporary obstruction, and single observation values ​​lack redundant verification, limiting the accuracy of data processing.

[0004] With the acceleration of urbanization, high-rise buildings, buildings in complex terrains, and buildings with diverse decorative materials are becoming increasingly common, highlighting the shortcomings of traditional settlement monitoring equipment in terms of applicability, efficiency, and accuracy. The market urgently needs a settlement monitoring device that can adapt to different wall materials (such as perforated walls and non-perforated decorative walls), reduce the number of station transfers, improve monitoring efficiency and accuracy, and possess good stability and anti-interference capabilities.

The front ends of the first and second side plates are rotatably connected by a first pin. The first pin is connected to a mounting plate to fix its position. The top and bottom rear ends of both the first and second side plates are rotatably connected to adapters via second pins. A mounting plate is located behind the first and second side plates, and the adapters are slidably connected to the mounting plate to adjust the angle between the first and second side plates.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0032] Example 1

[0033] like Figure 1As shown, a device for observing building settlement includes a first side plate 1 and a second side plate 2. Both the outer surfaces of the first side plate 1 and the second side plate 2 are provided with barcode observation areas 11. This design allows for settlement observation from two directions from a single observation point, facilitating comparison and averaging of the acquired settlement data from both sides, thus improving the accuracy of the observation data. The front ends of the first side plate 1 and the second side plate 2 are rotatably connected by a first pin 6. The first pin 6 is connected to a mounting plate 4 to fix its position. This structure facilitates adjustment of the angle between the first side plate 1 and the second side plate 2, thereby allowing for easy adjustment of their orientation. This enables the entire observation device to be installed at the most suitable angle according to observation requirements, improving the flexibility of the entire observation device. The top and bottom of the rear ends of the first side plate 1 and the second side plate 2 are rotatably connected to adapters 3 via second pins 7.
