Description

TECHNICAL FIELD

[0001] The utility model relates to light steel keel detection technical field especially light steel keel test bench. BACKGROUND

[0002] Light steel keel is a kind of new building material, with light weight, high strength, waterproof, shockproof, dustproof, sound insulation and other functions, widely used in hotel, terminal building, station, shopping mall, factory, office building and other places.Mechanical properties are one of the important properties of light steel keel, and it is also a conventional detection project, and its main test is static load test.

[0003] At present, the operation of static load test on light steel keel is as follows: first, place the light steel keel on the test bench, then install the mechanical dial gauge under the keel and record the initial data, then load the test load manually, and manually read the keel loading deflection and residual deformation after the specified time, but, in the detection process, since the light steel keel is directly placed on the test bench, the test bench is not convenient for limiting the light steel keel, which leads to the movement of light steel keel during loading test, and further affects the accuracy of test data.

[0004] Therefore, we propose a light steel keel test bench to solve the above problems. UTILITY MODEL CONTENTS

[0013] In further embodiments, the head end of the plug rod is in a conical structure.

[0014] Compared with the prior art, the utility model has the advantages that:

[0015] When the double-end screw in the support table rotates, it drives a pair of clamping plates to move closer to or away from each other, thereby clamping or releasing the light steel keel to be detected, and supporting the light steel keel while limiting its position, so as to reduce the position deviation of the light steel keel when the load is applied to the light steel keel during the detection process, thereby improving the accuracy of the detection data. In addition, the height of the entire rack can be adaptively adjusted, thereby being used in cooperation with the feeding and discharging conveying belt, so as to realize the automatic feeding and discharging of the test rack, thereby saving the trouble of manual feeding and discharging, and improving the detection efficiency.
