Abstract

The utility model discloses a concrete beam static loading test device. Currently, a long-term static loading test device is used for loading by mostly adopting a method of stacking heavy objects, so that the loading metering is not correct and cannot perform a whole-process destroy test. The concrete beam static loading test device comprises channel steel (1), wherein two pieces of channel steel are connected by batten plates; a concrete beam support seat (3) is fixedly arranged on the channel steel; a concrete beam testing piece (4) is arranged on the concrete beam support seat; a loading distribution beam (5) is arranged on the concrete beam testing piece by round steel (6); a loading pull rod (8) with a tension sensor (7) is arranged between the loading distribution beam and the channel steel; the loading pull rod is connected with a loading counterforce frame (10) by virtue of a hydraulic jack (9); and the tension sensor is connected with a display device (11). The concrete beam static loading test device disclosed by the utility model is used for concrete beam static loading test.

Description

Beams of concrete static loading test device
Technical field:
The utility model relates to field of civil engineering, is specifically related to a kind of beams of concrete static loading test device.
Background technology:
The fundamental construction of China at present is own through entering the newly-built stage of developing simultaneously with reform and maintain, understanding the concrete component Long-term mechanical behavior has become one of key content of Structural Engineering research at present, is one of comparatively effective technological means wherein and beams of concrete is carried out long-term static loading test.
At present long-term static loading test device adopts methods such as stacking weight to load mostly, so Load measurement is inaccurate and can not carry out the overall process failure test.Loading weight is large owing to adding, thus test specimen and charger take up an area larger, mobile very inconvenient after loading, reduce the utilization factor in place, laboratory, this is also test of long duration the number of components one of the main reasons on the low side.
Summary of the invention:
The purpose of this utility model is to provide a kind of beams of concrete static loading test device, for flexural member Long-term mechanical behavior and the experimental study of holding reinforcement under the lotus condition provide a kind of simple and practical static loading method.
Above-mentioned purpose realizes by following technical scheme:
A kind of beams of concrete static loading test device, its composition comprises: channel-section steel, 2 described channel-section steels connect by batten plate, be installed with the beams of concrete bearing on described channel-section steel, on described beams of concrete bearing, the beams of concrete test specimen is installed, loading distribution beam is arranged on described beams of concrete test specimen by round steel, the loading pull bar of pulling force sensor is installed between described loading distribution beam, described channel-section steel, described loading pull bar is connected with reaction frame for loading by hydraulic jack, and described pulling force sensor is connected with display device.
Described beams of concrete static loading test device, the end that described loading tensile bar is connected with described hydraulic jack has screw thread, on described screw thread, nut is installed, and between described nut and described loading distribution beam, backing plate is installed.
Described beams of concrete static loading test device is equipped with stiffening rib between described channel-section steel.
Beneficial effect:
1. the utility model shows stressed value by pulling force sensor by display device, utilizes the rotatable nut of active tool spanner until the value of thrust of demarcating, so just flexibly the controlled loading vertical force to testing setting value.Stablize for guaranteeing to load for a long time, answer the reading of periodic observation display device in test, in time adjust value of thrust.
2. the utility model can utilize reaction frame and load pull bar and realize the long-term static loading of beams of concrete and the experimental study of holding reinforcement under the lotus condition, simple in structure, floor area is little, reusable and removable, Loading Control is convenient, detect data accurately and reliably, can satisfy the test of beams of concrete Long-term mechanical behavior and the test of short-term sustained strengthening to the requirement of loading system.
