Background technology
The structure glue of using in the glass curtain wall, when bearing for a long time Action of Gravity Field (producing long-term shear creep), can bear the wind load perpendicular to stress surface, therefore a kind of creep test device of bidirectional stress need be provided, simulate in esse fluid sealant biaxial stress state.
Adopt the creep device among the patent CN201653826U, upper and lower four jiaos of its test specimen all have pulling claw to fix, and can produce specified force additional force in addition, affect the correct stress of fluid sealant.For example, when vertical direction did not have load, the power that applies on the horizontal direction can cause fluid sealant generation deformation, produced thus molecule segment and moved the stressed of offset by the level of direction, reached the state of a balance; If apply certain load on the vertical direction, while is the application of force in the horizontal direction, can be different according to friction factor in pulling claw and test specimen contact position, produce friction force not of uniform size, the part or all of transverse force of offset by the level of direction, causing the detrusion on the horizontal direction is not the distortion that the actual power that applies on it produces, thereby does not react actual operating position, does not reach the purpose of test.
Simultaneously, creep is under long-term (approximately 3 months) of bidirectional force effect, investigates the deformation on the shear direction.But within the so long time; all can there be variety of issue in itself using electricity system and equipment; such as the phenomenon that has a power failure or the equipment downtime generation is static; cause power can not continue maybe can not change; if load application again; the phenomenon that must presence bit retract again not exclusively (certain permanent strain is arranged), again repeatedly stretches affects the accuracy of creep measurement.
The utility model content
Technical problem to be solved in the utility model is for the deficiency in the background technology, provide and accurately to control simultaneously test specimen and stand stressed for a long time on horizontal and vertical two directions, and can accurately measure the bidirectional stress creep testing machine of a kind of mechanical connection of transverse shear deformation.

The two ends close contact of the crossbeam of support stand and the upper corrosion resistant plate of test specimen, lower basal plane is unsettled, and by upper platen and location, support stand end, makes the contact position that any displacement not occur.
Described horizontal loading system comprises the link that arranges on the unsettled lower corrosion resistant plate, and link passes through the steel wire connecting trays, and loads with counterweight.
Described axial loading system comprises the hole on the lower corrosion resistant plate, is connected with steel wire on the hole, and steel wire is walked around the fixed pulley that supports on the stand column and is connected with the pallet that vertical direction load is used, and loads with counterweight.
On the corrosion resistant plate relatively with hole other end close contact displacement transducer, displacement transducer is fixed on the column of support stand.
Link is positioned at the centre of lower corrosion resistant plate.
Laterally the load of loading system and the load of axial loading system all load by gravity.
Support in the stand and be provided with simultaneously at least two test specimens.
Support under the stand pulley is installed.
The utility model affects the movement of fluid sealant in the situation that horizontal loading system and axial loading system load can not produce other additional forces, can characterize in esse stress form more accurately.Its precision of displacement transducer is accurate to 0.001mm, can accurately measure fluid sealant in the deformation under the lasting shear load effect and the deformation set after the unloading.Load all loads by gravity, in long-term test period, is not powered, the impact of the extraneous factor such as plant machinery fault stressed direction and the accuracy of maintenance that can be continual, lasting.Can test simultaneously a plurality of test specimens, guarantee accuracy and the reappearance of specimen test.It is equipped with pulley, can under stress proving installation be moved under the various environment, investigates it under different temperature, damp condition impact, the croop property after the attenuation of fluid sealant and the decay.
