Spherical multidirectional force measuring support

Abstract

The invention relates to a spherical multidirectional force measuring support base. The spherical multidirectional force measuring support base comprises an upper support plate, a combined downswing, a base and a plurality of pressure sensors. The bottom surface of the upper support plate is a convex spherical surface, the top surface of the combined downswing is a concave spherical surface, the concave spherical surface is spliced by two identical concave spherical surfaces or four identical concave spherical surfaces, and the upper support plate contacts with the combined downswing in a spherical mode. The pressure sensors in the horizontal direction are arranged between the combined downswing and vertical walls of the base. The spherical multidirectional dynamometric support base can be utilized as supports for bridges, buildings or other engineering structures to measure and monitor various loads including dead load, dynamic load, impact load, earthquake load, additional load caused by temperature variation, and the like.

Description

technical field [0001] The invention relates to a force-measuring support, in particular to a spherical multidirectional force-measuring support capable of automatically testing loads acting on structures in the vertical direction and in various horizontal directions. Background technique [0002] With the continuous advancement of engineering technology, the spanning capacity of bridge structures is increasing, and the structural types are becoming more and more complex and diverse. The common feature of these long-span complex bridge structures is that they all belong to high-order statically indeterminate structures, and the calculation of their internal forces is very complicated. Due to the influence of various factors such as the error caused by the simplification of the calculation model, the difference in the mechanical properties of the material, the construction error, and the uneven temperature change of each part of the structure, the internal force of the struct...

The common feature of these long-span complex bridge structures is that they all belong to high-order hyperstatically indeterminate structures, and their internal force calculations are very complicated.

Due to the influence of various factors such as the error caused by the simplification of the calculation model, the difference in the mechanical properties of the material, the construction error, and the uneven temperature change of each part of the structure, the internal force of the structure during construction or after completion differs greatly from the design value. Moreover, these differences are difficult to estimate, burying certain safety hazards for the later use of structures
