Automatic scraping device for long-strip concrete ground and flatness control method of automatic scraping device

Abstract

The invention discloses an automatic scraping device for a long-strip concrete ground and a flatness control method of the automatic scraping device. The device comprises equal height scraping rails which are located on the two sides of the upper surface of a concrete cushion layer correspondingly and a control center, a traveling device is arranged on each scraping rail, a plow-type scraper bladeis fixed between the two traveling devices, stress sheets are attached to connecting positions of the two ends of the plow-type scraper blade and the traveling devices, and a camera is arranged on one of the traveling devices; the control center controls the traveling devices to travel along the corresponding scraping rails so as to drive the plow-type scraper blade to trowel the concrete ground;the two stress sheets are used for detecting stress values on the two sides of the plow-type scraper blade and transmitting the stress values to the control center, and the control center adjusts thetravel speed of the two traveling devices according to the stress values, so that the two traveling devices can travel synchronously; and the camera shoots the cast-in-place concrete scraping effectin real time and transmits shooting images to the control center. According to the automatic scraping device, on-site construction efficiency and precision are improved, and the ground flatness is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an automatic leveling device for long concrete floors and a flatness control method thereof. Background technique [0002] At present, flatness control is one of the key quality parameters of concrete floors. Scraping of cast-in-place concrete is a key construction step to control the flatness. At present, the commonly used method is to manually use wooden scrapers or aluminum alloy rulers to scrape the concrete, and the control measures are relatively extensive. The main structure of a certain project is a semi-buried pool with a length of 400 meters, a width of 18 meters, and a depth of 10.3 meters. The bottom plate concrete of the deep-water drag pool is divided into 9 blocks and poured in stages according to the expansion joints. The largest concrete floor of the block is about 1392m 3 . [0003] If the traditional method is used, about 2 hours after the concr...

Problems solved by technology

[0003] If the traditional method is used, about 2 hours after the concrete is poured and tamped (before the initial setting of the concrete), after the surface of the concrete has slightly collected water, use an iron roller to compact the two sides back and forth vertically and horizontally, and then scrape it again with a long scraper, and then use an artificial wooden crab to Leveling, the workload on site is large, the labor intensity of workers is high, the efficiency is low, and it is difficult to control the flatness of the bottom of the pool. In addition, the reinforcement grid laid on the cushion layer during pouring will also bring inconvenience to the movement of workers
