Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete test molds, and specifically relates to a high-compressive concrete test mold. Background Technique
[0002] Concrete, simply referred to as "concrete", is a general term for engineering composite materials in which a binder binds aggregates into a whole. Usually, the term "concrete" refers to cement concrete made with cement as the binder, sand and stone as aggregates; mixed with water (which may contain additives and admixtures) in a certain proportion and stirred, also known as ordinary concrete, which is widely used in civil engineering.
[0003] The existing patent document CN2230444Y for a mold for concrete tests proposes that the utility model consists of a bottom template, large side plates, and small side plates to form a mold cavity. Its main structure is a fastening mold for the mold cavity composed of bull-headed fasteners, T-shaped tie rods, and relief springs. The T-shaped tie rod with a relief spring connects the bull-headed fastener to the bottom template. Adopting a fastening method where the inclined surface template coincides with the inclined surface of the bull-headed fastener, with four-point force on one axis, two tie rods are used for each test mold, and the design is compact. It is convenient for users to disassemble and assemble. At the same time, it has the characteristics of high interchangeability of components, reduced labor intensity and product cost, and improved use accuracy of the mold, and is suitable for concrete compression, flexure and other tests.
[0004] However, although the existing patent CN2230444Y has the characteristics of high interchangeability of components, reduced labor intensity and product cost, and improved use accuracy of the mold, and is suitable for concrete compression, flexure and other tests, when the pressure applied by the mold is relatively large, it may cause the concrete block to be displaced.
