Description
Technical field
The utility model relates to a kind of reaction frame, particularly relates to a kind of novel student experimental reaction frame bridging.
Background technology
Student's experimental reaction frame bridging is mainly used in school's test test specimen and loads, but there is following problem in student experimenting reaction frame used in existing teaching: (1) existing student experimenting reaction frame crossbeam is arranged in the middle of two channel columns, do not stretch out to channel column both sides, one group of student's test can only be used for like this, two groups or three groups of student's tests can not be carried out simultaneously, be not easy to teaching; (2) link position of crossbeam and two channel columns is fixing, can not realize the adjustment of beam height; (3) connection between existing student experimenting reaction frame building block is all generally welding, can not dismantle, be inconvenient to transport.
Summary of the invention
The utility model provides a kind of novel student experimental reaction frame bridging, to overcome the problems referred to above deficiency.
For achieving the above object, the utility model adopts following technical scheme: a kind of novel student experimental reaction frame bridging, it is characterized in that: comprise two channel columns, crossbeam, base, pier, lifting jack, force cell, force value display, distribution beam and test specimen, described two channel columns vertically arrange and are welded on base, and base is connected with ground by bolt; Described crossbeam to be connected with two channel columns by secure component and to stretch out channel column both sides; Described pier is placed on the ground, and quantity is at least two, is provided with bearing, test specimen, bearing, distribution beam, lifting jack and force cell successively from top to bottom above pier, described force cell with contact bottom crossbeam and be electrically connected with force value display.
Preferred: described secure component is high-strength bolt and nut, connect fastening and test force request can be met.
Further: described two channel columns are provided with multiple screw so that the adjustment of beam height.
Further: described bearing is hold-down support or sliding support.
Further: the height of described two channel columns is 3 meters.
Further: described test specimen is free beam.
The utility model beneficial effect is:
(1) crossbeam stretches out channel column both sides, and Students in Teaching can carry out test specimen load test in two channel column both sides and centre position simultaneously, and one multiplex, facilitates Teaching;
(2) crossbeam is connected with two channel columns with nut by high-strength bolt, connects fastening and can meet test force request;
(3) two channel columns are provided with several screw so that the adjustment of beam height;
(4) except channel column and base are for except being welded to connect, be all dismountable between other parts of reaction frame, install and convenient transportation;
(5) test specimen is changed conveniently.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
In figure: 1-channel column, 2-crossbeam, 3-base, 4-pier, 5-lifting jack, 6-force cell, 7-force value display, 8-distribution beam, 9-free beam, 10-hold-down support, 11-sliding support, 12-high-strength bolt, 13-nut, 14-screw.
Embodiment
Below in conjunction with accompanying drawing, the utility model and embodiment thereof are described in further detail.
Fig. 1 is a preferred embodiment of the present utility model.As shown in the figure: a kind of novel student experimental reaction frame bridging, comprise two channel columns 1, crossbeam 2, base 3, pier 4, lifting jack 5, force cell 6, force value display 7, distribution beam 8 and test specimen, in the present embodiment, test specimen is free beam 9.Described two channel columns 1 vertically arrange and weld on the base 3, and base 3 is connected with ground by bolt (not shown).Described crossbeam 2 to be connected with two channel columns 1 by secure component and to stretch out channel column 1 both sides, and secure component is preferably high-strength bolt 12 and nut 13, and by using high-strength bolt, crossbeam 2 is connected with two channel columns 1 more fastening and can meets and test force request.Crossbeam 2 stretches out channel column 1 both sides, and Students in Teaching can carry out free beam 9 load test in two channel column 1 both sides and centre position simultaneously, and one multiplex, facilitates Teaching.Described pier 4 holds test specimen for cushion cap, and pier 4 is placed on the ground, and quantity is at least two, and the present embodiment battery of tests coordinates carrying by two piers.Be provided with bearing, free beam 9, bearing, distribution beam 8, lifting jack 5 and force cell 6 from top to bottom successively above pier 4, described force cell 6 with contact bottom crossbeam 2 and be electrically connected with force value display 7.Described bearing is hold-down support 10 or sliding support 11, type of support can be arranged according to different tests, hold-down support 10 transmits vertical force and horizontal force, allow superstructure freely can rotate at bearing place but can not move horizontally, sliding support 11 only transmits vertical force, allows superstructure freely can rotate at bearing place and can move horizontally.
Described two channel columns 1 are provided with several screw 14 so that the adjustment of crossbeam 2 height.
The height of described two channel columns 1 is 3 meters.
Utility model works mechanism is: loaded test specimen by lifting jack classification, observes the destructiveness of test specimen.After test specimen is finished using, the test specimen that can freely more renew, easy to operate.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
