Device for detecting horizontal load resistance of guardrail on site and using method thereof

Abstract

Disclosed are a device for detecting the horizontal load resistance of a guardrail on site and a using method thereof. The device comprises a frame, a thrust device, a measuring device and a reactiondevice; the thrust device comprises an adjustable base, a loading device, a horizontal thrust rod and an adjustable support rod; the measuring device comprises a measuring frame, a measuring rod and ameasuring instrument; the measuring frame comprises a pair of adjustable measuring frames, the measuring rod is fixed on the measuring frame, the measuring instrument is fixed on the measuring rod, the measuring frame is in a shape of forward extension, and the measuring rod is placed on a side opposite to a thrust receiving side of the guardrail; the reaction device comprises at least one of a telescopic reaction rod, an anchor reaction hook and a reaction force bracket. The device for detecting the horizontal load resistance of the guardrail on site is convenient to operate, can be carried,assembled and measured by a single person, and can adapt to the measurement of the guardrail in various complicated occasions, and the measuring method is precise, convenient, simple and quick in operation.

Description

technical field [0001] The invention relates to the field of measurement, in particular to an on-site detection device for guardrail anti-horizontal load and an application method thereof. Background technique [0002] Guardrails play the role of separation and guidance in use, and are important safety facilities on bridges and buildings. Injury accidents frequently occur due to insufficient horizontal load resistance of guardrails. Therefore, all countries have made mandatory horizontal load strength of guardrails. Regulation. [0003] According to the "GB50009-2012" building structure load code, "JG / T342-2012" building glass and metal guardrail test method requirements, when testing the civil building protection guardrails composed of metal railings and metal or glass material railings, the usual practice The relevant parties send the relevant materials to the testing agency, and then simulate the installation of various guardrails in the laboratory and conduct inspection...

AI Technical Summary

Problems solved by technology

However, due to factors such as different heights, different shapes, and different positions of the actual installation site of the railings, it is necessary to prepare different detection plans according to the site conditions during the test. Specialized technicians are required to formulate plans and build test devices according to the site conditions. The measurement is cumbersome, low in efficiency, and poor in operability, often due to the unreasonable construction of the detection device, resulting in unreliable measurement results

[0005] Patent CN206648758U discloses a horizontal thrust measuring device, the structure is relatively simple and easy to install, but its pressure seat (4) needs to be fixed with ground nails, which will damage the ground, and can only be used for the measurement of unfinished sites, and the operation is cumbersome. High professional level requirements, still not suitable for large-scale promotion and use
