Abstract
The utility model relates to a combined steel pattern plate load testing device, relating to a load testing device, which is used for checking the strength and the rigidity of the combined steel pattern plate. The combined steel pattern plate load testing device comprises a supporting seat, a poise, a hydraulic jack, a regulating screw, a dial gauge, a loading stand, a vertical balance stabilizing screw nail, a vertical balance pin shaft, a balance supporting seat, a transverse balance stabilizing screw nail, a transverse balance pin shaft, a loading cutter edge frame, a lower supporting cutter edge seat and a checking platform. When the hydraulic jack is unloaded, the positions of the vertical balance stabilizing screw nail, the transverse balance stabilizing screw nail and the poise is regulated, and the loading frame is maintained horizontality, and the dial indicator data are read out. Then the hydraulic jack is added pressure, the cutter edge of the loading cutter edge frame is separated from the combined steel pattern plate, and the return to zero data of the dial indicator is read out. The difference between the two data is the strength or rigidity of the combined steel pattern plate.
Description
Combined steel formwork loading test device relates to the loading test device.Be used to check the test unit of intensity, rigidity and the welding quality of combined steel formwork.
There is not at present the perfect test unit of a cover to check intensity, rigidity and the welding quality of combined steel formwork as yet.
The purpose of this utility model provides a kind of combined steel formwork loading test device, and it can check the quality of intensity, rigidity and the welding of combined steel formwork.
The utility model is achieved in that with clamp nut (16) adjusting screw(rod) (5) is connected with lower support edge of a knife seat (15) that balance bearing (10) is movably hinged by lateral balance bearing pin (12) with loading edge of a knife frame (13).Loading frame (7) is movably hinged by longitudinal balance bearing pin (9) with balance bearing (10).Be screwed with the firm screw of longitudinal balance (8) on the table top of loading frame (7).The both sides of balance bearing (10) are screwed with the firm screw of lateral balance (11) respectively.The Magnetic gauge stand (18) of dial gauge (6) is placed on the detection platform (17).Dial gauge (6) is placed on the below on the span centre point dual-side edge of combined steel formwork (14).
The utility model is further specified as follows below in conjunction with accompanying drawing:
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the A-A cut-open view of Fig. 1.
Fig. 3 is the B-B cut-open view of Fig. 1.
Fig. 4 is the C-C cut-open view of Fig. 2.
Among the figure: 2. the firm screw 12. lateral balance bearing pins 13. of the firm screw 9. longitudinal balance bearing pins of bearing 3. hydraulic jack 4. counterweights 5. adjusting screw(rod)s, 6. dial gauges, 7. loading frames, 8. longitudinal balances 10. balance bearings 11. lateral balances load edge of a knife frame 14. combined steel formworks 15. lower support edge of a knife seats 16. clamp nuts 17. detection platform 18, Magnetic gauge stand.
Detection platform (17) is placed on the ground (1), with clamp nut (16) with adjusting screw(rod) (5) be placed on the detection platform (17) after lower support edge of a knife seat (15) connects.The depth of parallelism between adjusting screw(rod) (5) scalable two lower support edges of a knife seat (15) is shelved on combined steel formwork (14) on the lower support edge of a knife seat (15).Loading edge of a knife frame (13), balance bearing (10) and loading frame (7) is placed on the combined steel formwork (14) successively.The below at loading frame (7) two ends is placed with one group of bearing (2) and hydraulic jack (3) respectively.The both sides of loading frame (7) respectively are placed with one group of counterweight (4) that weight is suitable.
Under the situation of hydraulic jack (3) unloading, slightly unclamp two firm screws of longitudinal balance (8), adjust loading frame (7) and go up the distance of counterweight (4) longitudinal balance bearing pin (9), make loading frame (7) in vertical maintenance level, at this moment, the force action line of counterweight (4) vertically passes through the axial line of longitudinal balance bearing pin (9).And then two firm screws of longitudinal balance (8) are turned downwards, it is held out against on balance bearing (10).To keep the vertically firm of loading frame (7).
Then, slightly unclamp the firm screw of two lateral balances (11), guaranteeing under the constant condition of each counterweight (4) and longitudinal balance bearing pin (9) distance, adjust counterweight (4) distance of lateral balance bearing pin (12) relatively, make loading frame (7) in horizontal maintenance level, at this moment, all the force action line of counterweight (4) is vertically by the lateral balance axis, and then the firm screw of two lateral balances (11) turned relatively, it is held out against loading on the edge of a knife frame (13), to keep the laterally firm of loading frame (7).
By adjusting the position of counterweight (4) on loading frame (7), then the specified trial load force action line that born of combined steel formwork (14) must be vertically by combined steel formwork (14) geometric center.And be two edges of a knife by loading edge of a knife frame (13) and act on equably on the combined steel formwork (14).Can survey the load test data of reading combined steel formwork (14) this moment by dial gauge (6).
Two hydraulic jack (3) are pressurizeed simultaneously, and jack-up loading frame (7) reposefully makes two edges of a knife that load edge of a knife frame (13) break away from combined steel formwork (14), can survey time remainder certificate of reading after the unloading by dial gauge (6) then.
Get load test data and the difference that unloads back remainder certificate, be the rigidity or the strength test data of combined steel formwork (14).
The utility model can carry out loading test to the combined steel formwork of plurality of specifications, and easy to use, and test error is little.
The utlity model has simple in structure, easy to manufacture, cost is low, easy to use, the advantage such as error is little.
