Novel experiment slide bearing device

Abstract

The invention provides a novel experiment slide bearing device which comprises a bottom plate, four side steel plates, roller shafts, slide rails and bolts. Two slide rails are positioned on a lower side plate which is fixed by the bottom plate, bolt ports are arranged on the outer sides of the slide rails at every certain intervals, an upper side plate is a foldable plate, the left end and the right end of the upper side plate can be folded to the middle through a pivot, the width of each section of the foldable plate corresponds to the bolt ports on the outer sides of the slide rails, clamp strips are arranged on two sides of each section of the foldable plate, clamp groves are arranged on a left plate and a right plate at the corresponding positions, roller shafts are arranged on the inner sides of the upper plate, the lower plate, the left plate and the right plate of the slide bearing device, the roller shafts of the upper plate and the lower plate use the centers of plates as axes, and the roller shafts of the left plate and the right plate can move up and down. The slide bearing device is suitable for experiment members of various sizes. The novel experiment slide bearing enables stress situation to be close to an ideal mode, improves experiment accuracy, greatly improves reliability of experiment data and further enables people to well know mechanical property of experiment members and materials.

Description

technical field [0001] The present invention relates to the technical field of sliding support, specifically a new type of sliding support device for testing, that is to provide a supporting connection that only provides vertical support reaction force during the test so that the specimen can move horizontally. Compared with the existing sliding support, the invention effectively reduces the gap between the test piece and the support constraint and the test error caused by it, and greatly improves the accuracy of the test result. The present invention is suitable for tests that only need to provide vertical support and reaction force devices. Background technique [0002] With the development of my country's economy, the safety performance of buildings and the diversification of building materials have attracted much attention. It is necessary to understand various mechanical properties of building components and building materials before design and construction, which need...

Problems solved by technology

However, most of the existing sliding bearings cannot be adjusted in size. When the size of the test member does not match the size of the supporting device, due to the large gap between the test member and the inner roller on the upper surface of the support, the sliding bearing will Failure to give sufficient vertical restraint to the specimen in time

This will cause the real force model to be inconsistent with the theoretical model, so it will cause a large error in the test results
