Description
Technical Field
[0001] The invention relates to the technical field of flatness detection, and in particular to a device for detecting the flatness of concrete components of high-rise buildings. Background Art
[0002] High-rise buildings are residential buildings with a building height greater than 27m and non-single-story factories, warehouses and other civil buildings with a building height greater than 24m. Concrete components are inevitably needed in the construction process of high-rise buildings. Concrete components are an indispensable part of construction projects. They are made of cement, sand, gravel and water mixed in a certain proportion and then cast. This material is widely used in various building structures due to its high strength, durability and economy. Concrete components can be made into different shapes and sizes to meet different engineering needs. For example, basic components such as beams, slabs, and columns constitute the skeleton of the building, while stairs, balconies, awnings, etc. provide additional functions and usage space. The surface flatness of the concrete structure is an important indicator affecting the quality of concrete. The surface flatness of the concrete structure directly affects the appearance of the concrete structure. Therefore, in the construction process of high-rise buildings, it is generally necessary to use the corresponding flatness detection device to detect whether the surface flatness of the concrete components is qualified.
[0003] Most of the existing flatness detection devices for concrete components have fixed structures, which are not convenient for adjusting their own horizontal height, resulting in that the flatness detection devices for concrete components cannot ensure their own levelness when the ground at the construction site is uneven, which easily affects the flatness detection accuracy of the concrete components, thereby failing to accurately judge whether the surface flatness of the concrete components is qualified. In addition, the existing flatness detection devices for concrete components can only perform flatness detection on one position on the surface of the concrete component at a time, and cannot achieve continuous detection of the entire surface, which is time-consuming and labor-intensive, and the detection efficiency is low. Therefore, the present invention proposes a flatness detection device for high-rise building concrete components to solve the problems existing in the prior art. Summary of the invention

The second screw rod 35 is driven to rotate downward by turning the turning handle, and the supporting cushion block 36 is driven to descend until it contacts the ground, which plays a certain positioning role for the mobile base 1 and ensures the stability of the mobile base 1.
[0032] When it is necessary to detect the flatness of the surface of a concrete component during the construction of a high-rise building, the high-rise building concrete component flatness detection device is first moved to the construction site, and then the handle is turned to drive the second screw 35 to descend, so as to drive the support pad 36 to descend and contact the ground, so as to realize the positioning and fixing of the mobile base 1. At this time, the mobile base 1 may not be able to maintain a level due to the ground of the construction site. In order to make the component placement plate 5 in a horizontal state to ensure the detection accuracy of the concrete component, the balance adjustment mechanism on both sides of the top of the mobile base 1 is adjusted to drive the balance adjustment plate 3 to adjust the left and right tilt until the level meter 37 on the front of the driving frame 6 shows a horizontal state, so that the balance adjustment plate 3 and the component placement plate 5 are in a relatively horizontal state, and then the concrete component to be detected is placed on the top of the component placement plate 5, and the concrete component is clamped and fixed by the component clamping mechanism, and then the top plate 8 is driven to move up and down by the lifting adjustment mechanism, so as to drive the infrared laser emitter 9 and the infrared sensor 10 to rise and fall synchronously respectively. According to the standard specifications of the concrete component, the infrared laser emitter 9 and the infrared sensor 10 are adjusted to appropriate positions respectively, so that the infrared laser output by the infrared laser emitter 9 can just pass through the surface of the concrete component and be detected by the infrared sensor 10, and then the synchronous driving mechanism is started to drive the front and rear two groups of bottom plates 7 to move synchronously, so as to drive the infrared laser emitter 9 and the infrared sensor 10 to move synchronously horizontally, and make the infrared laser output by the infrared laser emitter 9 move along the surface of the concrete component. When the surface of the concrete component is uneven, the infrared laser output by the infrared laser emitter 9 will be blocked, so that the infrared sensor 10 cannot sense the infrared laser. At this time, the PLC control system of the system drives the prompt light 11 to flash, and the surface flatness of the surface concrete component is unqualified. Repeat the above steps, by flipping and turning the direction of the concrete component, the upper and lower surfaces of the concrete component are respectively tested for flatness from different directions. When the flatness test results of the upper and lower surfaces are qualified, it indicates that the concrete component shows that the flatness meets the standard.
