Handheld positioning device of energy-saving precast part exposed reinforcements and application method

Abstract

The invention relates to a handheld positioning device of energy-saving precast part exposed reinforcements and an application method. The device comprises a guide rail, a bracket and a moving pair, wherein the guide rail comprises a first guide rail and a second guide rail; the first guide rail and the second guide rail are arranged in parallel; the bracket is strip-shaped; one ends of the firstguide rail and the second guide rail are connected to the bracket, and the end parts of the other ends are leveled; the first guide rail and the second guide rail are vertically connected with the bracket; the moving part comprises a first slide block, a second slide block and a connecting rod; the first slide block and the second slide block are slidingly connected with the first guide rail and the second guide rail, and are connected through a connecting rod; and the connecting rod is perpendicular to the first guide rail and the second guide rail. According to the sizes of components, the position of the positioning device and the lengths of the exposed reinforcements are freely adjusted; and the whole device is lower in weight and convenient for manual operation, prevents errors causedby manual disturbance, and effectively improves the construction working quality in mass production of products with fixed exposure sizes.

Description

technical field [0001] The invention relates to the technical field of building engineering construction tools, in particular to a hand-held positioning device for energy-saving prefabricated exposed steel bars and a use method thereof. Background technique [0002] Prefabricated components refer to various components manufactured by preforming methods. Unlike on-site manufacturing, preformed components are usually completed in a professional factory and then transported to the site for use. This concept is mainly used in the field of construction. According to the material properties, it can be divided into steel structure prefabricated components, wood structure prefabricated components, concrete prefabricated components, stone prefabricated components, etc. Among them, the concept of concrete prefabricated components is the most widely used. In the field of construction, prefabricated components are usually equated with reinforced concrete prefabricated components or pre...

AI Technical Summary

Problems solved by technology

The length of the exposed steel bars is not uniform, and the position is deviated, resulting in a large number of PC components that are prone to quality problems during the production stage. Therefore, the size of the exposed steel bars of the PC components needs to be strictly controlled

When the existing PC mobile formwork table and fixed formwork table are binding steel bars, the control of the exposed size of the steel bars is manually adjusted with a steel ruler, and the steel bars can only be bound after the individual long directions are measured and fixed with a self-made iron frame and a steel ruler. There are self-made iron frames. It is too bulky and inconvenient to carry manually. The self-made positioning device is easily disturbed during the production process of the laminated board. The positioning accuracy is not high and the error is large.
