Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and in particular to a metering device and method for construction of a building protection net. BACKGROUND

[0002] In the construction process of a building protection net, the protection net is usually needed to be used at any time, and accurate metering of the length of the protection net is a key link for guaranteeing smooth construction, ensuring engineering quality and reasonably controlling cost. In the metering and outward conveying process of the protection net, reliable positioning measures are lacked on both sides, which leads to frequent deviation and shaking of the protection net during movement. Due to lack of effective support in the middle part, the unstable conveying state makes the moving path of the protection net in the metering device disordered, and the metering device is difficult to accurately judge the length of the protection net according to the set metering mode, resulting in a large metering error. Moreover, the protection net of the traditional equipment is usually wound together when being wound, which is easy to cause metering deviation and is easy to cause the actual position of the protection net to be inconsistent with the ideal position during metering, greatly affecting the accuracy of metering. At the same time, due to factors such as material difference and uneven weight distribution, the protection net is prone to wrinkling and twisting. The actual length of the wrinkled and twisted protection net during metering will be significantly deviated from the length measured by the metering device, thereby affecting the cutting, splicing and other operations of the protection net during construction, causing material waste and construction delay. The thickness of the protection net cannot be flexibly adjusted, and inaccurate marking will cause the construction personnel to make mistakes in judging the length of the protection net, resulting in material waste.
