Abstract
The utility model belongs to the technical field of reinforced concrete member is experimental, a experimental pivoting support of displacement slidingtype concrete simple beam is related to. This pivoting support includes the H -beam, the billet, and the steel roller bearing, the cell type fastener, steel roller bearing both sides weld steel backing plate, the cell type fastener is connected bottom the H -beam, and the cell type fastener can be followed H -beam length direction and freely slided, steel roller bearing upper portion billet and the welding of cell type fastener. This pivoting support can be followed test beam length direction and freely removed, can accurate change the load point distance, realize the test beam cut stride than freely changes, can effectively improve experimental precision, this pivoting support simple structure, the installation simply, to the concentrated loading of test beam can make things convenient for, the change of accuracy cuts to stride and compares.
Description
Technical field
This utility model belongs to reinforced concrete member experimental technique field, relates to a kind of displacement slidingtype concrete simply supported beam test pivoting support.
Background technology
The static test of reinforced concrete member is the stress characteristic of research concrete component, and the basic means of material property is used widely in concrete field.For the beams of concrete under Concentrated load, shear span ratio has appreciable impact to the stress performance of structure, directly determines destructive characteristics and the collapse state of component.Therefore, in component test, the change of shear span ratio often becomes an important design parameter.In identical test operating mode, the most accurately and easily change shear span ratio, change the loading spacing of component the most accurately, test accuracy and test efficiency are had a major impact.
Utility model content
The purpose of this utility model is design a kind of displacement slidingtype concrete simply supported beam test pivoting support, it is achieved accurately and easily change shear span ratio.
For achieving the above object, displacement slidingtype concrete simply supported beam test pivoting support the technical scheme is that this pivoting support includes I-beam, billet, steel roller bearing, grooved fastener, steel roller bearing both sides welding billet, grooved fastener is connected with bottom I-beam, grooved fastener can move freely along I-beam length direction, and steel roller bearing upper steel backing plate welds with grooved fastener.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is elevation of the present utility model.
Wherein 1 I-beam, 2 billets, 3 steel roller bearings, 4 grooved fasteners, 5 loads, 6 test beams, 7 testing bed, testing stands.
Detailed description of the invention
Such as Fig. 1, shown in Fig. 2, this pivoting support includes I-beam 1, billet 2, steel roller bearing 3, grooved fastener 4, steel roller bearing 3 both sides welding billet 2, grooved fastener 4 is connected bottom I-beam 1, and grooved fastener 4 can along I-beam 1 length direction slidably, and steel roller bearing 3 upper steel backing plate 2 welds with grooved fastener 4.This pivoting support can move freely along test beam length direction, can accurately change the distance of load(ing) point, it is achieved freely changing of test beam shear span ratio.
