Multifunctional steel wire rapid moving calibration bar

Abstract

The invention provides a multifunctional steel wire rapid moving calibration bar which comprises a plurality of fixed supports which are correspondingly arranged at the two sides of the rapid moving calibration bar at equal intervals, a plurality of sliding supports are arranged between every two corresponding fixed supports at intervals and connected with one another through steel wires, the two ends of each steel wire are fixed on fastening spanners of the two fixed supports, the steel wires are supported by the fixed supports and sliding wheels on the sliding supports, and the tip of each steel wire is higher than the wing edge of each sliding wheel. The rapid moving calibration bar can be fixed on a wall surface through the fixed supports at the two ends and tack claws on the bottom surfaces of the sliding supports in the middle. The steel wires are tensioned through fastening devices of the fixed supports at the two ends of the calibration bar, and the effect of controlling the paving thickness and the flatness of mortar can be achieved. The distance between the steel wires and the base layer wall surface is adjusted through the fixed supports and adjusting nuts of the sliding supports in the middle of the calibration bar so that the calibration bar can adapt to the unevenness of the base layer wall surface. The calibration bar is convenient and rapid to arrange and can be repeatedly used.

Description

technical field [0001] The invention relates to a marking bar for controlling the thickness and flatness of mortar paving in large-area plastering construction, in particular to a multifunctional fast movable steel wire marking bar for controlling the thickness and flatness of mortar paving. Background technique [0002] In general building construction, the mortar paving and leveling process of large-area plastering construction (mechanical or manual) adopts manual or mechanical paving and leveling process, and the thickness of mortar paving and leveling accuracy depend on the preset fixed standards. Muscle control. The fixed marking bar adopts the same ratio of mortar, the marking bar is 40-50mm wide, and the spacing of the marking bar is about 2000mm (less than the length of the scraper bar). The surface of the marked reinforcement is the plastered surface, and the distance between the surface of the marked reinforcement and the base wall is the height of the marked rein...

AI Technical Summary

Problems solved by technology

[0004] 1. High technical requirements: the width of the standard reinforcement is required to be uniform; the surface of the standard reinforcement is a plastered surface, and the surface is straight, which must be higher than the specification requirements; the standard reinforcement must be firmly bonded to the wall

[0005] 2. The investment of technical workers is large: the mortar marking bars need to be completed manually, and the corresponding labor must be equipped according to the number of marking bars, and they must be skilled professional technical workers

[0006] 3. Long construction period: The wet work of artificially setting mortar bars takes a long time, and after completion, it needs to stop for a necessary technical interval time (that is, the maintenance of mortar) to ensure that the mortar bars reach a certain strength

[0007] 4. Cannot be prefabricated and reused: Mortar reinforcement is a reinforcement fixed at a specific position on the wall. It must be operated on the base after the completion of the base wall. It is a one-time use and becomes a part of the plastering surface of the wall.

[0008] The above-mentioned characteristics of mortar marking ribs make this process unable to adapt to the current development trend of high labor costs and high mechanization, especially in the "mechanical spraying and plastering method", which obviously weakens the advantage of mechanization in construction period, and also makes mechanization The economies of scale The advantages cannot be fully realized
