Tensile strength detection device for embedded member of light prefabricated panel

Abstract

The invention relates to a tensile strength detection device for an embedded member of a light prefabricated panel. The tensile strength detection device consists of a rigid bracket on which a foundation fixing seat, a sample limiting member and a weighing bracket are arranged, and a metering and force-measuring assembly which comprises a steelyard hook provided with a traction assembly end, a weigh beam consisting of a weighing end, a metering end and a support ring, a metering weight and a weigh shaft. Being developed specific to the characteristics of light dead weight of the light prefabricated panel and small load bearing force of the embedded member as well as the current situation of no proper detection device, the tensile strength detection device has the characteristics of simple and reasonable structure, low setting cost, convenience in use, reliability in work and high test data repeatability, can be applied to professional manufacturing plants as well as construction site inspection equipment, and is very high in practicability. The blank of the tensile strength detection device for small-load embedded members is filled up, and the technical support is provided for market access of embedded externally-mounted light prefabricated panels, so that the tensile strength detection device is wide in market application prospect.

Description

technical field [0001] The invention relates to the technical field of building material mechanics testing equipment, in particular to a device for testing the pullout strength of pre-embedded components of lightweight prefabricated wallboards characterized by small load testing. Background technique [0002] With the advancement of science and technology and the enhancement of people's awareness of environmental protection, lightweight prefabricated wall panels, such as polystyrene particle wall panels, aerated concrete wall panels, polystyrene foam composite wall panels, due to their light weight and excellent thermal insulation, sound insulation and It is favored by the characteristics of low price and convenient on-site installation. Due to the loose internal structure of this type of wallboard, expansion screws cannot be used to fix the installation. For this reason, at present, the method of fixing and installing the wallboard on the steel beam of the building frame is...

AI Technical Summary

Problems solved by technology

However, due to the loose texture of the lightweight prefabricated wallboard itself, the load-bearing capacity of the installation and connection components buried in it is relatively small, and the ultimate pull-out load is only about 500Kg, while the pull-out force used in the construction industry is mostly 1 ton The above jack-type load measuring device is obviously not up to the task
