A simulation device for extrusion experiments of reinforced concrete structural parts

Abstract

The invention discloses an extrusion experiment simulation device for a reinforced concrete structure, which comprises a base, a beam plate, a piezoelectric detector, a hydraulic oil measuring cylinder, an upper pressing block and a lower pressing block, and the middle part of the upper end of the base is fixed with a The lower pressing block is provided with a guide rod on the outside of the lower pressing block, and the top end of the guide rod is connected to the beam plate. An upper extrusion plate is installed at the bottom of the upper pressing block. Several extrusion teeth are arranged at the bottom of the upper extrusion plate. A reinforced concrete structure is placed under the teeth, and the reinforced concrete structure is placed on the lower extruded plate. A number of extruded teeth are arranged on the upper surface of the lower extruded plate, and the lower extruded plate is embedded and installed on the lower pressing block; The stability of the connection between the beam plate and the guide rod, the extrusion operation of the lower extrusion plate and the upper extrusion plate on the reinforced concrete structure clamped in the middle, the extrusion effect is good; it also realizes the extrusion force during the extrusion simulation operation The detection operation can effectively detect the extrusion force of the reinforced concrete structure.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to an extrusion experiment simulation device for a reinforced concrete structure. Background technique [0002] Reinforced concrete is usually called reinforced concrete in construction engineering. It refers to a composite material that is formed by adding steel bars, steel mesh, steel plates or fibers to the concrete to work together with it to improve the mechanical properties of concrete. Concrete generally refers to cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures if necessary, in an appropriate proportion, after uniform mixing, compact molding and curing hardening. stone. The strength grade of concrete added with steel bars, steel mesh, steel plates or fibers is also enhanced by the standard of cubic compressive strength. Structural parts made of reinforced concrete, such as: reinforced concret...

AI Technical Summary

Problems solved by technology

The reinforced concrete structure of a general house needs to have high compressive performance, but there is a lack of relevant testing equipment for the detection of the compressive strength of reinforced concrete. Conventional extrusion equipment can only detect the static compressive strength of reinforced concrete structural members. The concrete structure is crushed under pressure, but the compressive strength value of the concrete structure cannot be detected, and sufficient experimental data cannot be provided for the simulation of the extrusion experiment
