Abstract
The invention relates to an axial tension test hinge mechanism capable of eliminating eccentric bending moment. The axial tension test hinge mechanism comprises a steel plate unit, a pin and an inverted T-shaped plate. The steel plate unit is arranged at an upper part of the axial tension test hinge mechanism of eliminating eccentric bending moment and comprises a transverse plate and three vertical plates. The transverse plate is arranged at the middle part of the steel plate unit. One of the vertical plates is arranged in the middle of the top of the transverse plate, and the other two are arranged respectively at two sides of the bottom of the transverse plate and are connected to the inverted T-shaped plate by the pin. Compared with the prior art, the axial tension test hinge mechanism capable of eliminating eccentric bending moment can be used as a whole, wherein during an axial tension test, the two axial tension test hinge mechanism can be arranged respectively at two sides of a tension test sample, and can move in two directions which are orthogonal with each other so that a pull force is applied to the tension test sample by the two axial tension test hinge mechanism, and thus eccentric bending moment is eliminated and test result accuracy is guaranteed. Therefore, the axial tension test hinge mechanism capable of eliminating eccentric bending moment can be widely utilized for building structure tests and building structures.
Description
Technical field
The present invention relates to a kind of Structural Engineering scrap disassembling technical device field, especially relate to a kind of axial tension test hinge body of eliminating eccentric bending moment.
Background technology
In similar field, the main testing machine that adopts of axial tension test relies on artificial adjustment centering to reduce eccentric bending moment at present.Obviously, there is certain deficiency in this test method.Because rely on artificial adjustment centering, unavoidably have deviation.
When load hour, the eccentric bending moment of generation is little, but along with the increase of load, eccentric bending moment can increase gradually, therefore the deviation to test findings also can increase gradually.Therefore, for directly utilizing the pulling force clamping to carry out tension test, bias factor will inevitably appear in data result.
Also do not have at present the related patent U.S. Patent No. technology to propose to eliminate the tension test hinge body of moment of flexure, and along with the development of the fast development, particularly steel construction of China's building structure, must increase yet the wood property research and experiment of construction material.The present invention promptly is that the direct tensile test for adhesion test between thick formed steel construction fire resistant coating and the steel plateelement and thick type frie retardant coating designs, and the cohesive strength of test and tensile strength are all lower, and the existence of eccentric bending moment will directly influence test findings.And the tension test hinge body that uses the present invention to propose can have been eliminated eccentric bending moment effectively, thereby guarantees that test specimen makes an experiment under axle draws stress, also has high precision to guarantee to test findings.
In sum, research a kind ofly is widely used, the tension test hinge body of the elimination eccentric bending moment of superior performance is one of goal in research of those skilled in the art.
Summary of the invention
The object of the invention is exactly to propose a kind of warranty test axial tension test hinge body of the eccentric bending moment eliminated of accuracy as a result that is used for for the defective that overcomes above-mentioned prior art existence.
The object of the invention can be realized through following technical scheme:
A kind of axial tension test hinge body of eliminating eccentric bending moment is characterized in that this device is made up of steel plate group, pin and inverted T shaped plate, and described steel plate group is located at device top, is connected with inverted T shaped plate through pin.
Described steel plate group is made up of a transverse slat and three risers, and described transverse slat is located at the middle part, and a riser is located at the centre position at the top of transverse slat, and other two risers are located at the position of transverse slat two bottom sides.
The upper end of described inverted T shaped plate is stretched between two risers of steel plate group bottom, is connected with riser through pin.
Compared with prior art; The present invention can completely use, and two hinge bodies lay respectively at the two ends of tensile test specimen to be tested, the activity direction quadrature of two hinge bodies; Pulling force applies pulling force through hinge body to tension test; Eliminated the existence of moment of flexure, warranty test result's accuracy, thus can be widely used in Architectural Structure Experimentation process and the building structure self.
