It is detailed to a kind of working principle progress of the antisitic defect system for single-beam load test provided by the invention below
Explanation.
When test, the both ends of T beam are separately positioned in sub-truss, two supporting steels of two oblique 1 upper ends of mobile jib
Plate 5 is contacted with the web of T beam two sides respectively, and when T beam is tilted to the direction of supporting steel plate 5, supporting steel plate 5 plays branch to T beam
Support effect, the lateral pressure of T beam are passed to by supporting steel plate 5 to entire sub-truss, due to sub-truss triangular structure, when
When T beam rolls, by the inclination pressure of entire sub-truss shared T beam, the stability of T beam is improved；Simultaneously as by
The T beam of support can be freely vertically movable, so the accuracy of T load bearing beam's aptitude tests result can't be disturbed.
Occur to roll in single-beam or when lateral bending, upper end supporting steel plate generates the power along beam transverse direction to resist beam body, the power
Appearance will offset the unbalanced moment of beam, to solve the problems, such as this.In order to enable the support force provided offsets imbalance enough
Moment of flexure makes full use of advantage of the truss member in terms of bearing pressure using symmetrical girder system, the lateral branch generated
Support force is transmitted on ipsilateral concrete pier nose anchor by oblique rod piece and vertical bar, also can be through simultaneously because compatibility of deformation
Vertical bar and horizontal bars are transmitted to the oblique mobile jib of symmetrical side, then are transmitted to concrete pier connected to it by oblique mobile jib
On head anchor, so that the common stress in truss two sides, promotes limitation of the system to beam body inclination and lateral bending.
In single-beam load, in order to reduce the influence that the horizontal direction support force of sub-truss measures single-beam bearing capacity,
It is coated with lubricant at the supporting steel plate of upper end, does not influence the vertical deflection of beam body.Meanwhile in the pressure sensing of upper end supporting steel plate
Device can test transverse horizontal force, and the lateral force current to beam body controls, and adjust loading position.
Further, the rubber cushion blocks with lubricant and pressure sensor are placed in the web of test T beam by supporting steel plate 5
Place when the oblique pressure of T beam is greater than the set value, and can carry out early warning by host computer, guarantee that the position of load is accurate.
Meanwhile the cost of the system is low, can be recycled, is readily transported and assembles, and does not have too big cost for T beam test
Increase.
Further, the system can prevent in T beam test the destruction of beam even can in test early warning, and will not be right
The result of test is influenced, use value and promotional value with higher.
The above content is merely illustrative of the invention's technical idea, and this does not limit the scope of protection of the present invention, all to press
According to technical idea proposed by the present invention, any changes made on the basis of the technical scheme each falls within claims of the present invention
Protection scope within.
