Problems solved by technology

However, there are many factors that cause shrinkage and deformation of concrete structures. In addition to the raw materials, mix ratio, and age of the concrete structure itself, the ambient temperature and humidity of the concrete structure are important factors that determine the degree of shrinkage of the concrete structure. Conditions, the shrinkage deformation produced inside different concrete structures is not consistent, so the shrinkage stress inside the concrete structure in the actual application environment is generally difficult to be consistent with the

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] figure 1 and figure 2 Both are schematic diagrams of monitoring devices for shrinkage and deformation of concrete structures in the embodiments of the present invention. The shrinkage and deformation monitoring device of the concrete structure is applied in the concrete structure 1 , that is, when in use, the shrinkage and deformation monitoring device of the concrete structure needs to be buried vertically upward in the concrete structure 1 to be monitored. like figure 1 and figure 2 As shown, the monitoring device for shrinkage and deformation of the concrete structure in the embodiment of the present invention includes: a metal bucket 2 , a soft layer 3 and a strain gauge 4 .

[0021] The metal bucket 2 has a verticall...

Abstract

The embodiment of the invention discloses a monitoring device for contraction distortion of concrete structure. The device comprises a metal bucket, a soft layer and a strain gauge. The embodiment of the invention also discloses a monitoring method for contraction distortion of concrete structure. With the above device and method adopted, the condition of contraction distortion of large concrete structure in the whole service life can be precisely monitored in real time, thus performing reliable safety assessment to project structures.

Description

technical field [0001] The invention relates to the technical field of engineering structure test measurement, in particular to a monitoring device and method for shrinkage deformation of concrete structures. Background technique [0002] In the field of industrial and civil buildings, for some important large concrete structures or large prestressed concrete structures (such as nuclear power plant containment, road bridges, large industrial plants, etc.), it is generally necessary The stress status of the structure is tracked and monitored to ensure the normal operation and use of the concrete structure. [0003] As time goes by, various concrete structures in the actual application environment will not only deform due to external stress, but also shrink and deform due to the shrinkage of the concrete structure, that is, when the concrete structure hardens in the air, it will gradually The volume of the concrete structure shrinks due to the heat dissipation and hardening p...
