Strength detection device for weather-resistant anti-corrosion plywood

Abstract

The invention provides a strength detection device for a weather-resistant anti-corrosion plywood, and relates to the technical field of board strength detection. The strength detection device for the weather-resistant anti-corrosion plywood comprises a box body, a lower clamp is arranged on the inner bottom surface of the box body, a hydraulic cylinder is arranged on the upper inner wall of the box body, an upper clamp is arranged at the output end of the hydraulic cylinder, and each of the upper clamp and the lower clamp comprises a workbench, an adjusting cap, a clamping block and a connecting rod. The adjusting caps are rotationally connected to the left side face and the right side face of the workbench respectively, the lower portions of the connecting rods are in threaded connection with the adjusting caps and are in sliding connection with the workbench, and the ends of the upper sides of the connecting rods are fixedly connected with the clamping blocks. Cold water in a cold water tank or hot water in an electric hot water tank is sprayed out through a nozzle of a spray head plate, so that an I-shaped weather-resistant anti-corrosion plywood is in a wet and cold or humid and hot environment, and a relatively reliable strength value of the weather-resistant anti-corrosion plywood can be obtained after the I-shaped weather-resistant anti-corrosion plywood is tested; in the testing process, the state of deformation or bonding stripping can be obtained according to a high-speed camera.

Description

technical field [0001] The invention relates to the technical field of plate strength detection, in particular to a strength detection device for weather-resistant and anti-corrosion plywood. Background technique [0002] Plywood is a three-layer or multi-layer board-like material that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber directions are glued perpendicular to each other. [0003] Plywood is one of the commonly used materials for furniture, and it is one of the three major boards of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. A group of veneers are usually assembled and glued together according to the direction of the wood grain of adjacent layers perpendicular to each other. Usually, the surface board and inner layer board are symmetrically ar...
