TECHNICAL FIELD
[0001] The present application relates to the construction technology field of post-poured belt, in particular to a monitoring device for judging the pouring time of post-poured belt concrete. BACKGROUND
[0002] The post-poured belt is arranged at the bottom plate, wall, beam and other positions of the concrete building structure, which divides the whole structure into multiple parts, and is used for eliminating the cracks caused by the uneven settlement (vertical displacement difference) between the structures of each part, concrete shrinkage and temperature influence. Selecting the pouring time of post-poured belt concrete is an important work. The traditional method is to pour the concrete of the post-poured belt after the single-day settlement difference increment (vertical displacement difference) of the concrete on both sides of the post-poured belt tends to zero and the concrete shrinkage is completed, so as to make the structure as a whole. Therefore, the settlement of the structures on both sides of the post-poured belt needs to be monitored during construction, so as to analyze the settlement difference and provide a basis for determining the pouring time. At the same time, the concrete construction of each part of the structure needs to be completed for several days before the post-poured belt concrete construction, so as to eliminate the cracks caused by the concrete shrinkage. At present, according to this method, cracks still appear in the beam and slab of the main structure when the pouring time of the post-poured belt is selected. The reason is that only the settlement data is monitored as the judgment basis, and the relative displacement of the structures on both sides of the post-poured belt (i.e. the width data of the groove after pouring the post-poured belt) caused by temperature changes, concrete shrinkage and other factors is not detected. The existing equipment needs to be monitored by independent monitoring structures when detecting the changes in the width direction, which leads to a large amount of monitoring work. SUMMARY
[0003] The present application aims to provide a monitoring device for judging the pouring time of post-poured belt concrete, which can monitor the changes in both settlement and width, and solves the problem that the existing equipment cannot monitor the settlement and width changes of the concrete on both sides of the groove at the same time.
