Crack Inducing Members and Crack Inducing Structures

Abstract

The invention relates to a concrete crack induction structure, and discloses a crack inducer. The crack inducer (1) is columnar, and the crack inducer (1) has an upper bottom surface (11) of the inducer and a lower bottom surface of the inducer ( 12), the upper bottom surface (11) of the inducer is an outwardly convex arc surface, and the lower bottom surface (12) of the inducer is a plane or an arc surface concave toward the upper bottom surface (11) of the inducer . The invention also discloses a crack induction structure. The crack inducer of the invention can form cracks with smaller width on the concrete pavement, and the cracks produced are relatively uniform, thereby ensuring the aesthetics of the concrete pavement and driving comfort.

Description

technical field [0001] The invention relates to a concrete crack induction structure, in particular to a crack induction piece. In addition, the present invention also relates to a crack-inducing structure. Background technique [0002] Concrete is one of the most important contemporary civil engineering materials. It is prepared according to a certain proportion by gel material, granular aggregate (also known as aggregate), water and, if necessary, admixtures and admixtures. It is a kind of artificial stone made by stirring, compacting and curing. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal e...

Problems solved by technology

Moreover, the location where cracks occur is a weak load area, and uncontrollable cracks will gradually widen or break under heavy traffic, affecting aesthetics and traffic

[0004] Common ways to solve the above problems in the field of construction are: (1) setting saw marks on the road surface. This saw mark is generally set when the concrete is solidified to be operable by workers, but the width of the saw mark is wider. To make the road surface smoother, it is necessary to fill the saw marks with suitable elastic materials, which increases the construction cost; (2) crack inducers are set at appropriate positions on the road surface, but the crack inducers in the prior art have a cross section of Quadrilateral, circular or triangular columns, through which the concrete cracks formed are relatively large, generally 3-10mm, and not uniform, which will affect the aesthetics of the road surface and the comfort of driving
