The device includes a box cover, a box body, a heating water tank, a plurality of temperature sensors, automatic windshield wiper components, a computer, a connecting component, support bases, a temperature control box, two supports, two beams, multiple separation supports, multiple heating pipes, multiple reflection targets, a plurality of debugging modules and multiple laser displacement sensors, wherein the bottom of the box body is provided with the heating water tank and the temperature control box, the top of each debugging module is provided with a refraction target, the automatic windshield wiper components are arranged on the box cover, the laser displacement sensors are connected with the computer through circuits, and each temperature sensor is connected with the temperature control box. The measurement device for the volume deformation of the foam concrete under the condition of steam curing is applied to the field of concrete deformation measurement.

Description

technical field [0001] The invention relates to a test device for volume deformation of foam concrete, in particular to a test device for volume deformation of foam concrete under steam curing conditions. Background technique [0002] With the development of society and economy, the large-scale construction of various infrastructures, municipal roads and bridges, civil engineering and so on has been increasing. In order to ensure the quality of building projects, reduce environmental pollution at construction sites, and adapt to the requirements of old city renovation, the state has vigorously advocated factory-based prefabricated production components and on-site installation and construction methods of prefabricated building technology in recent years. Therefore, in the next few years, the production of concrete prefabricated components in the country will inevitably increase. In order to speed up formwork turnover and improve production efficiency in the production of pr...
