Description

Technical Field

[0001] The utility model relates to the technical field of construction acceptance, in particular to a multi-functional quality acceptance device for beam-shaped structures. Background Technique

[0002] The square lattice beam slope protection is an engineering structure used for slope stability and protection. It consists of vertical and horizontal staggered square beams, forming a grid-like structure, and this design can effectively disperse the water flow and pressure on the slope surface. The square lattice beam slope protection can not only enhance the slope stability, but also reduce the risks of soil erosion and landslides. It is applicable to areas with various soil qualities and climatic conditions, and is widely used in mountainous areas, river banks, building foundation pits, etc.

[0003] When accepting the qualification rate of cast-in-situ square lattice beams, it is generally necessary to measure and accept the concrete protective layer of the steel bar cage, the distance between the main steel bars and the distance between the formworks respectively. Due to the existence of the slope, quality inspection and acceptance personnel need to rely on a tape measure and other auxiliary tools to measure the lengths of relevant parts, and it is also very difficult to achieve a level view when reading the numbers, resulting in problems such as cumbersome acceptance procedures and inconvenient reading.
