Description
Technical field
The utility model relates to civil engineering work pick-up unit field, particularly a kind of concrete component assembly type pressue device.
Background technology
When carrying out about test in prestress, steady load need be applied to small-size concrete component, and conventional concrete test block test machine cannot carry out cutting etc. to test block while loading, and other operate.Need in test to apply larger stress to concrete test block, this just requires that test unit can ensure security, must meet again test to the needs of pre-tension in precision.Therefore the problem that pressue device need solve has as follows:
1, owing to carrying out machinery release elastic deformation energy to concrete, inherently there is certain danger, destroy as vibration causes framework weakness, so need larger safety margin, the security of whole device during for ensureing Concrete Cutting;
2, do under stress relief test needs to gather certain load action, test block makees machinery when releasing energy, and can deform reply, at this moment just needs test unit can accurate controlled pressure, long-time stable can hold lotus;
3, if because test needs enough loads, but pressure-bearing device insufficient rigidity, the distortion itself produced may cause the impact of can not ignore to test findings.So experimental provision requires that framework has enough intensity, the factor such as to be out of shape in experimentation and can to ignore the impact of experimental result.
For above problem, impel us to find and a kind ofly both can apply stable continuation load to concrete test block, the operations such as cutting can be carried out to concrete test block again while loading, thus reach to the test block that there is strain carry out machinery release energy time, ensure that test block external loads does not change, the object of sustained loading stability with the change of test block deformation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, carries out the operations such as cutting while providing a kind of loading to concrete test block, accurately can control the concrete component assembly type pressue device that pressure, stability and security are good.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of concrete component assembly type pressue device, it is characterized in that: by bracing frame, high strength anchor bar, slim lifting jack, oil pressure gauge, retaining valve and oil pressure pump are formed, two high strength anchor bars be arranged in parallel, the two ends of two high strength anchor bars are installed on bracing frame respectively, space between two high strength anchor bars and two ends bracing frame forms concrete test block put area, at the slim lifting jack of inside fixed placement of a side stand component, the push rod of this slim lifting jack is towards concrete test block put area, this slim lifting jack connects oil pressure pump by oil circuit, and oil pressure gauge and retaining valve are installed on oil circuit.
And, be placed with billet respectively in the both sides of concrete test block put area.
And described bracing frame is welded and fixed dorsad by channel-section steel and forms.
And the end of two described high strength anchor bars extend out to bracing frame outer end and adopts high-strength nut to fix.
Advantage of the present utility model and beneficial effect are:
1, this concrete component assembly type pressue device, adopt two high strength anchor bars to be arranged in parallel, the two ends of two high strength anchor bars are installed in the structure on bracing frame respectively, and structure is closed, there is good stability, device can not be caused when testing to destroy and even produce dangerous.
2, this concrete component assembly type pressue device, adopts oil pressure pump, oil pressure gauge and retaining valve to form control pressurer system, can accurate controlled pressure, can provide the load of long-time stable.
3, this concrete component assembly type pressue device, when concrete component is larger, billet can be adopted to be delivered in test block by pressure uniform, billet is as pressure-containing member, its pressure-bearing part has larger rigidity, the distortion of can not ignore can not be produced under larger load action, thus ensure that data have enough little error.
4, the utility model scientific structure design is reasonable, namely stable continuation load can be applied to concrete test block, the operations such as cutting can be carried out to concrete test block again while loading, thus reach to the test block that there is strain carry out machinery release energy time, ensure that test block external loads does not change, the object of sustained loading stability with the change of test block deformation, be applied to and apply continual and steady load to concrete, inside concrete is made to produce stress, simulation prestressed component.
