Building engineering material witness sampling device and sampling method thereof

Abstract

The invention discloses a building engineering material witness sampling device and a sampling method thereof, relates to the technical field of building engineering material sampling, and aims to solve the problem that an existing witness sampling device cannot effectively and quickly sample materials. The device is characterized in that a fixing cylinder is arranged on one side of the upper end of a base, a driving box is arranged on the other side of the upper end of the base, a worm rod is installed in the fixing cylinder and is in sliding connection with the fixing cylinder, a driving gear is arranged at the lower end of one side of the worm rod, the driving gear is located in the driving box, the driving gear is matched with the external threads of the worm rod, an inner cylinder is arranged in the worm rod and slidably connected with the worm rod, a sampling cylinder is mounted in the inner cylinder, a sawtooth cylinder is integrally arranged at the bottom of the sampling cylinder, an adjusting ring and a fixing ring are arranged at the lower end in the sampling cylinder, metal blades are arranged between the adjusting ring and the fixing ring, the number of the metal blades is five, and the metal blades are distributed in a staggered and stacked mode.

Description

Technical field [0001] The present invention relates to the field of sampling of construction engineering materials, and is specifically a structured sample device for a construction engineering material and a sampling method thereof. Background technique [0002] Building materials are various materials applied in construction engineering. There are many kinds of building materials, which is roughly divided into: 1, inorganic materials, which include metal materials (including black metal materials and non-ferrous metallic materials) and non-metallic materials (such as natural stone, boiled articles, cement, concrete and silicate products, etc. 2, organic materials, which include plant materials, synthetic polymer materials (including plastics, coatings, adhesives) and asphalt materials; 3, composite materials, which include asphalt concrete, polymeric concrete, etc., generally inorganic non- The metal material is complicated with the organic material. [0003] Among them, witne...
