Description

Technical Field

[0001] The utility model relates to the technical field of mortar impermeability testers, and specifically relates to a mortar impermeability tester for mortar detection. Background Technique

[0002] Mortar is an artificial stone widely used in construction. For some buildings, such as hydraulic buildings, underwater, in water, underground and other construction projects, the building is required to have special properties - impermeability. The so-called impermeability refers to the property that the materials used in the structure can resist the penetration of water and / or other liquid (light oil, heavy oil) media under the action of pressure; the impermeability tester is used to determine the impermeability of waterproof sand, and conduct a comparative test between the mortar mixed with waterproof agent and the reference mortar. It is designed according to the hydraulic principle, with a motor driving a water pump to apply pressure, and is connected to a pressure vessel, a control valve, a test mold base, etc. through pipelines. The pressure is output from the water pump into the pressure vessel and then transported to each specimen system for a loading test;

[0003] When some existing impermeability testers are in use, in order to ensure the accuracy of detection, it is necessary to detect multiple groups of test blocks at the same time. By screwing multiple molds onto the impermeability tester for fixation, the overall disassembly and assembly are relatively troublesome, time-consuming and laborious, and it is not convenient for the detection of mortar; for this reason, a mortar impermeability tester for mortar detection is proposed. Content of the Utility Model

[0007] As a further preference of this technical solution: A connecting nozzle is installed between the inner side wall of the air pipe and the upper surface of the airbag automatic inflator.

[0008] As a further preference of this technical solution: Universal wheels are evenly installed on the lower surface of the detector.

[0012] When the present utility model is in use, a sealing material is coated on the outer wall of the impermeability test block, and the impermeability test block is placed and pressed from the lower end of the mold. The setting of being smaller at the top and larger at the bottom makes it difficult for the impermeability test block to be separated from the mold under pressure. The mold is sleeved on the positioning sleeve, and the clamping cylinder is rotated so that the fixing block rotates to the inside of the clamping block to limit the up and down of the clamping cylinder. The airbag automatic inflator is started to inflate the annular airbag. Under the block of the positioning sleeve and the retaining ring, the clamping cylinder is internally supported and can be closely attached to the clamping cylinder under the action of friction to complete the positioning of the mold. The impermeability of the impermeability test block is detected by the detector. After completion, the air is pumped out by the airbag automatic inflator to release the positioning of the annular airbag on the clamping cylinder. There is no need to frequently twist, and the overall disassembly and assembly are relatively simple, time-saving and labor-saving, and it is convenient to detect the mortar.

The lower side of the outer side wall of the annular airbag 8 is communicated with an air pipe 9. A plurality of airbag automatic inflators 10 are installed inside the detector 1. When in use, after the cured impermeability test block 4 is coated with a layer of sealing material 5 on its outer wall, the sealing material 5 can improve the sealing performance between the impermeability test block 4 and the mold 3. Then, the impermeability test block 4 is placed in from the lower end of the mold 3 and pressed tightly. The mold 3 is sleeved on the positioning sleeve 2. At this time, the upper end of the positioning sleeve 2 abuts against the lower end of the impermeability test block 4. The airbag automatic inflator 10 is started, and air is inflated into the annular airbag 8 through the air pipe 9. Blocked by the positioning sleeve 2 and the retaining ring 7, the annular airbag 8 expands outward and internally supports the clamping cylinder 6. Under the action of friction, it can be closely attached to the clamping cylinder 6 to complete the positioning of the mold 3. The impermeability of the impermeability test block 4 is detected through the detector 1. After the test is completed, the airbag automatic inflator 10 is used to pump air to release the positioning of the annular airbag 8 on the clamping cylinder 6. There is no need to frequently turn, and the overall disassembly and assembly are relatively simple, time-saving and labor-saving, which is convenient for the detection of mortar.

[0022] In this embodiment, specifically: the upper surface of the detector 1 is fixedly connected with a plurality of fixing blocks 11, and the outer side wall of the clamping cylinder 6 is fixedly connected with a pair of clamping blocks 12; by rotating the clamping cylinder 6 to make the pair of fixing blocks 11 rotate to the inside of the clamping blocks 12, the up and down of the clamping cylinder 6 can be limited.

[0023] In this embodiment, specifically: a connecting nozzle 13 is installed between the inner side wall of the air pipe 9 and the upper surface of the airbag automatic inflator 10; the connecting nozzle 13 facilitates the connection between the air pipe 9 and the airbag automatic inflator 10.

[0025] In this embodiment, specifically: a rubber ring 15 is bonded to the upper surface of the positioning sleeve 2; the rubber ring 15 can improve the sealing performance between the positioning sleeve 2 and the mold 3.

[0026] In this embodiment, specifically: the inner side walls of the mold 3 and the cross-section of the impermeability test block 4 are both trapezoidal, and the radius gradually decreases from bottom to top; through the setting of being smaller at the top and larger at the bottom, the impermeability test block 4 is not easily separated from the mold 3 under pressure.

[0027] The working principle of the present utility model is as follows: during use, a sealing material 5 is coated on the outer wall of the cured impermeability test block 4. The sealing material 5 can improve the sealing performance between the impermeability test block 4 and the mold 3. Then, the impermeability test block 4 is placed into the mold 3 from the lower end and pressed tightly. Through the setting of being smaller at the top and larger at the bottom, the impermeability test block 4 is not easily separated from the mold 3 under pressure. The mold 3 is sleeved on the positioning sleeve 2. At this time, the upper end of the positioning sleeve 2 abuts against the lower end of the impermeability test block 4. The clamping cylinder 6 is rotated so that a pair of fixing blocks 11 rotate to the inside of the clamping block 12, which can limit the up and down movement of the clamping cylinder 6. The airbag automatic inflator 10 is started, and air is inflated into the annular airbag 8 through the air pipe 9. Blocked by the positioning sleeve 2 and the retaining ring 7, the annular airbag 8 expands outward and internally supports the clamping cylinder 6. Under the action of friction, it can closely fit with the clamping cylinder 6 to complete the positioning of the mold 3. The impermeability of the impermeability test block 4 is detected by the detector 1.
