Description

Concrete placement thickness detection device for house safety Technical Field The invention relates to the technical field of concrete detection, in particular to a concrete pouring thickness detection device for house safety. Background In the construction of building engineering and the safety identification of the existing buildings, the thickness of structures such as concrete floors, shear walls and the like is a key control index for measuring engineering quality and guaranteeing structural bearing capacity and durability. If the thickness of the floor slab does not meet the design requirement, the structural safety of the house is directly affected, and serious problems such as cracking, water seepage and even insufficient bearing capacity of the floor slab can be caused. Therefore, the accurate and efficient detection of the concrete pouring thickness is an important link of engineering quality acceptance and safety identification. In the prior art, in the concrete pouring construction process, the thickness control of horizontal components such as a floor slab, a wall body and the like is a core index for guaranteeing the structural safety and the bearing capacity, however, the conventional concrete thickness detection means generally adopts a mode of 'post-inspection and acceptance' or 'pouring intermittent spot inspection', and the dynamic monitoring synchronous with the pouring operation is difficult to realize. The traditional drill rod insertion measurement needs to suspend pouring operation before initial concrete setting, a thickness value is read by manually inserting a drill rod, construction can be continued after the number to be read is finished, the mode of stop-measurement-recovery seriously interrupts continuous beat of concrete pouring, particularly in large-volume concrete or high-rise building floor pouring, frequent pump stopping and starting not only reduce construction efficiency, but also can cause that concrete stays in a pumping pipeline for too long to increase pipe blocking risks, bleeding or initial setting is easy to occur on the poured surface during interruption, cold joints are easy to form at new and old concrete joints after pouring is resumed, and hidden quality hazards are buried for structural integrity and waterproof performance; secondly, the existing ultrasonic or electromagnetic wave thickness gauge is mostly used for checking and detecting after concrete hardening or performing spot check in the pouring intermittent period, when the detection finds that the thickness is insufficient, the best adjustment time is always missed, only remedial measures such as polishing, slurry supplementing and the like can be taken after the concrete is solidified, not only material waste and construction period delay are caused, but also a new weak area can be formed when the slurry supplementing layer is poorly combined with the original structure, meanwhile, the type of instrument cannot effectively work due to high internal water content and unstable structure when the concrete is still in a flow molding state, the ultrasonic signals are seriously attenuated, the electromagnetic wave signals are easily distorted, reliable data are difficult to provide, more importantly, the data acquired by the existing detection means are all discrete point values, real-time linkage of a measuring result and construction operation cannot be realized, a constructor cannot know the thickness deviation of the current area in real time in the pouring process, only the cloth and the vibration thickness can be controlled through experience, the blind pouring mode is highly dependent on the technical level of operators, the thickness uniformity is difficult to ensure, and the single-point extraction and detection is very easy to miss the local weak area caused by micro deformation or uneven vibration of the template, the thickness distribution data of the continuous section cannot be formed, and the traceable process record is also lacking when the quality problem occurs in the later stage. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a concrete pouring thickness detection device for house safety, which aims to solve the problems in the prior art. The technical aim of the invention is realized by the following technical scheme: The concrete pouring thickness detection device for house safety comprises a support rod, wherein a sliding block is movably sleeved on the outer circular wall surface of the support rod, a movable frame is fixedly arranged on the bottom surface of the support rod, and a PLC (programmable logic controller) is fixedly arranged on the top surface of the movable frame; the continuous detection assembly is arranged on one side of the sliding block and is used for continuously detecting the thickness in the concrete pouring process; the continuous detection assembly comprises a light weight frame, wherein the light weight frame is fix
