Abstract

The utility model belongs to the technical field of a bridge expansion device, and discloses a device for testing the clamping force of a sealing rubber belt of a modular-type expansion joint. The device is mainly characterized by comprising a working table with a counterforce bracket, wherein a fixing rod and an oil cylinder are arranged at the counterforce bracket; a horizontal steel bar is arranged at the bottom of the oil cylinder; the oil cylinder is connected with a pressure meter or a pressure sensor. Compared with the existing testing method, the device has the effects that a steel bar clearance of the modular-type expansion device is drawn out to reach a special value; the pressure is applied to the sealing rubber belt through the horizontal steel bar with specific diameter and length; the force value of the ejection of the sealing rubber belt is recorded, so that the clamping fastness of the sealing rubber belt is reflected by the force value. The testing method provided by the utility model is approximate to the actual force-bearing condition of the sealing rubber belt of the expansion device, thereby being a breakthrough of a detection technology for the bridge expansion device.

Description

Modulus formula expansion joint caulking gum band holding force test unit
Technical field
The utility model belongs to the bridge extension joint technical field, relates in particular to a kind of modulus formula expansion joint caulking gum band holding force test unit.
Background technology
Retractor device is the vitals of bridge, and along with the development of communication, vehicle flowrate increases, and heavy goods vehicles, overload car increase, and bridge extension joint damage problem becomes increasingly conspicuous.Disease of retractor device loses waterproof sealing for the breakage that comes off of caulking gum band, causes bridge substructure to pollute corrosion.Existing bridge extension joint is done waterproof test in 24 hours to the caulking gum band in detecting, but waterproof test can not reflect the holding force performance of caulking gum band, increase or after inner product full gravel dust wheel in shaped steel gap rolls the breakage that may come off of caulking gum band in retractor device shaped steel gap.Detect the gripping performance of retractor device caulking gum band, have important and practical meanings.
The utility model content
The technical problems to be solved in the utility model just provides a kind of modulus formula expansion joint caulking gum band holding force test unit that can detect the gripping performance of retractor device caulking gum band.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the worktable that has the counter-force support, described counter-force support is provided with fixed bar, oil cylinder, and the oil cylinder bottom is provided with horizontal rod iron, and oil cylinder is connected with pressure gauge or pressure transducer.
Its additional technical feature is: described horizontal rod iron diameter 20---30mm, length 500---550mm;
Described horizontal rod iron diameter 25mm, length 535mm; Described horizontal rod iron two ends are conical.
When modulus formula provided by the utility model expansion joint caulking gum band holding force test unit uses, modulus formula retractor device is placed on the worktable, 75 ± 10mm is drawn back in the shaped steel gap of modulus formula retractor device, caulking gum band between shaped steel and the position of horizontal rod iron are complementary, with the fixed bar of counter-force support modulus formula retractor device is fixed then, start oil cylinder, horizontal rod iron falls near the caulking gum band, load is loaded on the caulking gum band, and pressure gauge or pressure transducer come precise monitoring pressure.If the load forces of minimum 6000N of test sample failing to reach in test takes place just that the caulking gum band comes off or be damaged, then be regarded as test failure.If fail to reach this load forces more than once in 5 follow-on tests, then the prediction of modulus formula retractor device test is regarded as defectively, must improve design and tests again.If in 5 follow-on tests, only once fail to reach minimum load power, then can ignore test this time and on former sample, carry out continuous 3 tests separately again.If these 3 times tests all reach minimum load power, then be considered as success by test.
Modulus formula provided by the utility model expansion joint caulking gum band holding force test unit, compare with existing method of testing, particular value is drawn back in modulus formula retractor device shaped steel gap, the horizontal rod iron of pressure by special diameter and length is applied on the caulking gum band, the power value that record caulking gum band is ejected, the clamping fastness of the size reflection caulking gum band of power value.The actual loading operating mode of this kind method of testing and retractor device caulking gum band approaches, and is a breakthrough of bridge extension joint detection technique.As required, horizontal rod iron diameter 20---30mm, length 500---550mm, certain horizontal rod iron diameter 25mm, length 535mm are best.And horizontal rod iron two ends are conical, can avoid exposing the caulking gum band.
Description of drawings
Fig. 1 is the structural representation of the utility model modulus formula expansion joint caulking gum band holding force test unit.
Embodiment
Be described further below in conjunction with the structure of accompanying drawing to modulus formula provided by the utility model expansion joint caulking gum band holding force test unit.
As shown in Figure 1, modulus formula provided by the utility model expansion joint caulking gum band holding force test unit comprises worktable 1, worktable 1 has counter-force support 2, counter-force support 2 is provided with fixed bar 3, oil cylinder 4, oil cylinder 4 bottoms are provided with horizontal rod iron 5, oil cylinder 4 is connected with pressure gauge 6, horizontal rod iron 5 diameters 20---30mm, length 500---550mm, and horizontal rod iron 5 two ends are conical.
When modulus formula provided by the utility model expansion joint caulking gum band holding force test unit uses, modulus formula retractor device is placed on the worktable 1,75 ± 10mm is drawn back in shaped steel 7 gaps of modulus formula retractor device, the caulking gum band 8 of 7 of shaped steel and the position of horizontal rod iron 5 are complementary, with the fixed bar 3 of counter-force support 2 modulus formula retractor device is fixed then, start oil cylinder 4, horizontal rod iron 5 falls near caulking gum band 8, load is loaded on the caulking gum band 8, and pressure gauge 6 or pressure transducer come precise monitoring pressure.If the load forces of minimum 6000N of test sample failing to reach in test takes place just that caulking gum band 8 comes off or be damaged, then be regarded as test failure.If fail to reach this load forces more than once in 5 follow-on tests, then the prediction of modulus formula retractor device test is regarded as defectively, must improve design and tests again.If in 5 follow-on tests, only once fail to reach minimum load power, then can ignore test this time and on former sample, carry out continuous 3 tests separately again.If these 3 times tests all reach minimum load power, then be considered as success by test.
Modulus formula provided by the utility model expansion joint caulking gum band holding force test unit, compare with existing method of testing, particular value is drawn back in modulus formula retractor device shaped steel 7 gaps, the horizontal rod iron 5 of pressure by special diameter and length is applied on the caulking gum band 8, the power value that record caulking gum band 8 is ejected, the clamping fastness of the size reflection caulking gum band 8 of power value.The actual loading operating mode of this kind method of testing and retractor device caulking gum band approaches, and is a breakthrough of bridge extension joint detection technique.As required, horizontal rod iron 5 diameters 20---30mm length 500---550mm, certain horizontal rod iron 5 diameter 25mm length 535mm are best.And horizontal rod iron 5 two ends are conical, can avoid exposing caulking gum band 8.
