Fiber cloth realizes prestress application.
As patent No. 201320643923X discloses a kind of simple reaction rack equipment, the device, including by shaped steel welding
Into cross tube and montant, cross tube is arranged on montant upper end, and montant lower end is welded with the rhombus base that angle steel is made, rhombus bottom
Seat is provided with bolt hole.The device job stability is poor, and can not consider the principle of three branches so that test value and actual value
It is too wide in the gap.
Utility model content
Technical problem to be solved in the utility model is that there is provided a kind of job stability for there is the defect of test device
Strong and test point more conforms to the reinforced beam test of bearing capacity device of actual conditions.
Held in order to solve the above technical problems, the technical scheme that the utility model is used is a kind of reinforced beam limit
Carry power experimental rig, including reaction frame, roof beam structure post group and three points of framves, it is characterised in that the reaction frame by steelframe, force snesor,
Ball pivot and jack composition, wherein steelframe is the square being welded mutually by top girder steel, bottom steel beam, left steel column, right steel column
Steelframe, force snesor is installed in below the girder steel of top, and ball pivot is installed in below force snesor, and jack is installed in below ball pivot；Institute
Roof beam structure post group is stated for two steel columns and two post corner brackets, two steel columns are arranged on bottom steel beam and are close to left steel column and right steel respectively
Post, two post corner brackets are respectively installed on the top surface of two steel columns；Three points of framves include one and carry power girder steel and two beams
Corner bracket, two beam corner brackets are used for two three branch positions being installed on the reinforced beam for needing to test, and carry power girder steel dress
It is located on two beam corner brackets；Jack is installed in the center for carrying power girder steel.
The cubic shaped steel frame includes square shaped steel frame and rectangle steelframe.
In use, the two ends for needing the reinforced beam tested to be erected to two post angles of reaction frame inner beam trestle group
On frame, reinforced beam between two post corner brackets 1/3rd and 2/3rds at be respectively on reinforced beam
Two beam corner brackets are individually placed to two three branch positions by two three branch positions, then are placed on power girder steel is carried on beam corner bracket, so
Jack is placed on load power girder steel center afterwards, is constantly pressurizeed, reinforced beam is carried by manipulating jack so
Power is tested, and gathers the data of sensor, until Reinforced Concrete Beam Deformation or crack occurs, obtains ultimate bearing force data.
The beneficial effects of the utility model are that load power girder steel is placed on to three branch positions of test beam, can be obtained and real
The closer data of border applicable cases, because test beam is not individualism in practical application；Added on reaction frame
Ball pivot, can keep the stability of test job, and carrying force data can also be directly gathered by force snesor；The utility model
Simple in construction, easy operation, is adapted to widely popularize.
