Description
Technical field
The invention belongs to and detect and the road and bridge engineering technical field, relating to a kind of deck paving resistance to compression changes the tensile test device, is specially adapted to the detection of each articulamentum interlayer tensile strength of bridge floor, and the detection of ground surface material core tensile strength.
Background technology
Deck paving be the stress layer of bridge structure also be protective seam.In bridge operation process, because the large deflection of decking and temperature variation cause that bridge deck pavement produces bigger tension, the layer that causes mating formation produces a crack.
For guaranteeing traffic safety, the road-ability of bridge, give full play to the function of bridge, the tensile property that improves deck installation structure is significant.The equipment of the test material performance of using always in the highway engineering is generally and has resistance to compression materials with function testing machine at present, and tensile test equipment is many for detection of the bigger material of tensile strength such as reinforcing bar, and the size of its chuck is not suitable for the bridge pavement material, can't detect the tensile property of deck paving.
Summary of the invention
The invention discloses a kind of deck paving resistance to compression changes the tensile test device, to solve the problems such as tensile property that prior art can't detect deck paving.
The tensile test device is changeed in deck paving resistance to compression of the present invention, and technical solution is as follows:
Comprise and load frame, upper grip, load frame, lower chuck down; Last loading frame comprise load frame top frame, on load frame underframe, upper guide post; Under load frame and comprise and load down frame top frame, load frame underframe, guide pillar down down; Under load frame top frame and have the upper guide post through hole; The upper guide post through hole that loads frame top frame down cooperates with upper guide post, and upper guide post one end is fixedly mounted on and loads frame top frame, and the upper guide post other end is fixedly mounted on and loads the frame underframe; Has following guide pillar through hole on the last loading frame underframe; The following guide pillar through hole of last loading frame underframe cooperates with following guide pillar, and following guide pillar one end is fixedly mounted on down and loads frame top frame, and the following guide pillar other end is fixedly mounted on down and loads the frame underframe; Upper grip is fixedly mounted on down and loads frame top frame; Lower chuck is fixedly mounted on and loads the frame underframe; Last loading frame and lower chuck can be along guide pillar straight-line displacements down; Under load frame and upper grip can be along the upper guide post straight-line displacement; Upper grip, lower chuck are used for the fixed cylinder test specimen, when the top frame that loads frame instantly closely contacts with the underframe of last loading frame, will survey part and be positioned in upper grip, the lower chuck; After upper grip, lower chuck clamp test block; Upper grip moves up jointly with the top frame that loads frame down, and the underframe of lower chuck and last loading frame moves down jointly, thereby realizes the stretching to test block.
The present invention also comprises buffer spring; Buffer spring is installed on loading frame underframe and the following following guide pillar that loads between the frame underframe, prevents that the test specimen fracture from causing upward falling of loading frame.
Upper grip of the present invention, lower chuck inboard have anti-slip tank, prevent that test specimen to be measured and chuck are loosening in the process of the test.
The environmental cabinet that the tensile test device is vertically put into UTM or other loading testers is changeed in resistance to compression, read loading tensile by testing machine.
Good effect of the present invention is:Can be converted into pulling force to the pressure that Material Testing Machine provides, realize the detection to the deck paving tensile property.According to test objective and requirement, can select to heat up or cooling, full water or insatiable hunger water, measure the interlayer tensile strength of deck paving under the different conditions.Can detect the tensile strength of deck paving water-proof tack coat under different temperatures and the damp condition, detect tensile strength and the non-deformability of deck paving water-proof tack coat, in conjunction with test findings, can select suitable bridge deck water-proof tack coat material according to the different stresses of bridge structure, improve the whole usability of deck paving.Improve the road-ability of bridge, prolong the whole service life of bridge.
