Description
Technical Field
The invention relates to the technical field of concrete performance detection, in particular to a concrete impermeability detection device.
Background
The anti-permeability performance of concrete refers to the capability of the concrete to resist the penetration of pressurized water, and in general, when the anti-permeability requirement is designed on the concrete or the anti-permeability requirement is set on the concrete at a pouring position, the concrete should be left to be sampled and subjected to an anti-permeability test. At present, the impermeability of the concrete is detected generally by using a concrete impermeability instrument, the concrete impermeability instrument comprises a detection table and a sleeve arranged on the detection table through bolts, a plurality of fixing seats are arranged on the detection table, the sleeve is arranged on the fixing seats, a plurality of water outlet devices are respectively communicated with the fixing seats, the water outlet devices are further connected with valves, and a water pressure adjusting device is further arranged on one side of the detection table. Usually, a tester can manufacture a concrete test piece in advance according to a rule, then heat the sealed paraffin to be completely melted, roll the circumference of the test piece in the melted paraffin for a circle, repeat for 2-3 times, so that the circumference of the test piece is completely covered by the paraffin, and the paraffin is strictly forbidden at the two ends of the test piece, then press the test piece dipped with the paraffin into a sleeve at about 40 ℃ by a press machine, finally install the sleeve on a fixed seat and begin to check the impermeability of the concrete.
However, after the test piece is jacked into the sleeve by the press and is depressurized, the test piece can be retracted and rebound for a certain distance, so that a gap is formed between the test piece and the sleeve, and water leakage is easy to occur when a impermeability test is carried out on the test piece subsequently, so that improvement space is still reserved.
Disclosure of Invention
Aiming at the defects existing in the prior art, the invention aims to provide a concrete impermeability detection device.
In order to achieve the above purpose, the present invention provides the following technical solutions:
The utility model provides a concrete impermeability performance detection device, includes the detection platform and can dismantle a plurality of sleeves of being connected on the detection platform, the top of detection platform is equipped with a plurality of fixing bases, all open the delivery port in the fixing base, a plurality of the fixing base all is fixed with the sealing ring respectively, the sleeve can dismantle with the fixing base and be connected, the sleeve is articulated by two semicircle cylinders and forms, the sleeve is equipped with the connecting piece that is used for connecting two semicircle cylinders, telescopic inside wall is equipped with the packing piece that is used for sealing the gap between sleeve and the test piece.
According to the technical scheme, through the sleeve formed by hinging the two semicircular cylinders and the filling piece, when the outer side wall of the test piece is coated with paraffin, and the test piece is required to be placed in the sleeve, the semicircular cylinders are closed into the sleeve only by operating the two semicircular cylinders, the filling piece is tightly abutted against the test piece by operating the filling piece, the test piece can be placed in the sleeve, the outer side wall of the test piece is tightly abutted against one side, far away from the sleeve, of the filling piece, the compression of the test piece into the sleeve by a press machine is facilitated to be reduced, and due to the fact that a rebound force is generated between the test piece and the sleeve, the test piece and the sleeve are relatively displaced, the solidified paraffin between the test piece and the sleeve generates a gap, so that the water leakage condition of the test piece is easily caused when the impermeability is measured, the gap between the test piece and the sleeve is facilitated to be reduced, and the outer side wall of the test piece is facilitated to be sealed better; meanwhile, when the test piece is pressed into the sleeve by using the press machine, the sleeve is heated to the temperature required by paraffin melting in advance, and the test piece is placed in the sleeve in a hinged mode, so that the steps of heating the sleeve in advance and using the press machine are reduced, and the cost for detecting the impermeability of concrete is reduced.
The invention is further provided with: the connecting piece includes the connecting plate that stands out in the lateral wall of two semicircle barrels, runs through the bolt of connecting plate and with bolt threaded connection's nut, the connecting plate all opens the connecting hole that supplies the bolt to run through, the connecting plate is located the lateral wall of semicircle barrel and keeps away from the edge of articulated department, and when two the lateral wall butt of articulated department is kept away from to semicircle barrel, two the lateral wall butt of connecting plate, and two the connecting hole is just right.
By adopting the technical scheme, through the butt of two connecting plates, and run through two connecting plates through the bolt, make the head of bolt tightly support with one side of connecting plate, rethread nut threaded connection bolt, make the nut keep away from one side butt of bolt head with the connecting plate, make the bolt lock dead in the position of running through two through-holes, make two connecting plates continuously be in the state of mutual butt, thereby make two semicircle drums keep away from one side of articulated department together fixed, make two semicircle drums can synthesize telescopic state steadily, through the threaded connection of bolt and nut, make two semicircle drums can be in the state of two semicircle drums keep away from one side of articulated department mutual butt, be favorable to reducing because the connecting piece is connected unstably, easily lead to two semicircle drums to keep away from one side of articulated department and separate each other, thereby lead to there is the clearance between test piece and the sleeve and can not stabilize in the sleeve, and then lead to the condition of the impervious nature of unable measurement test piece, be favorable to testing the test piece better.
