Description

Technical Field

[0001] This utility model relates to the field of anti-permeability testing equipment, and more specifically to an anti-permeability testing device for building materials. Background Technology

[0002] Permeability testing of building materials is an important means of assessing the material's ability to resist penetration under water or liquid pressure;

[0003] The existing testing device, as shown in application number CN202220461796.0, "A Test Device for Waterproofing Materials in Building Construction", allows for the adjustment of the air pressure inside the casing by an air pump during the testing process, enabling the observation of the water penetration of the waterproofing material under different air pressure conditions; and the water penetration box is detachable, facilitating the installation and laying of the waterproofing material.

[0004] However, the disassembly and assembly structure of the permeation chamber of the above-mentioned testing device, which uses components such as pressure blocks and bolts to tighten the anti-seepage material for sealing and stability, is still relatively cumbersome in use and has the disadvantage of low testing efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a building material impermeability testing device in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] This utility model proposes a building material impermeability testing device, including a support, a test plate stably placed on the support, and a positioning mechanism fixed on the support.

[0008] One side of the test plate is a smooth surface;

[0009] The positioning mechanism includes a telescopic actuator fixed on a bracket, an open frame fixed at the output end of the telescopic actuator, a viewing window fixed on the open frame, and an annular sealing gasket that is fitted and fixed at the opening of the open frame.

The other end of the water inlet pipe is fixedly inserted through the inner and outer sides of the opening frame, and the water inlet pipe is a flexible hose.

[0014] As a preferred embodiment of this utility model, it also includes a pressurizing mechanism fixedly mounted on the bracket and the opening frame for pressurizing the gas supply in the sealed cavity, and a pressure sensor fixedly mounted on the opening frame, wherein the sensing end of the pressure sensor is connected to the opening frame.

[0015] As a preferred technical solution of this utility model, the pressurizing mechanism includes a vacuum pump fixed on the bracket, an air inlet pipe with one end connected and fixed to the suction end of the vacuum pump, an air intake pipe with one end connected and fixed to the discharge end of the vacuum pump, and a second one-way valve connected and installed between the air intake pipes.

Detailed Implementation

[0021] like Figure 1 As shown, this utility model proposes: a building material impermeability testing device, including a support 1, a test plate 2 stably placed on the support 1, and a positioning mechanism 3 fixed on the support 1;

[0022] The test plate 2 can be a rigid test material (such as a concrete slab) or a soft test material (such as a waterproof membrane or the "proof material pad" in the background technology "CN202220461796.0").

[0023] One side of the test plate 2 is a smooth surface. When it is a concrete plate, the top surface can be ground to provide a flat and smooth surface.

[0024] The positioning mechanism 3 includes a telescopic actuator 31 fixed on the bracket 1, an opening frame 32 fixed at the output end of the telescopic actuator 31, a viewing window 33 fixed on the opening frame 32, and an annular sealing gasket 34 attached and fixed at the opening of the opening frame 32. The telescopic actuator 31 can be an electric push rod or a cylinder, and the material of the annular sealing gasket 34 is rubber.

[0025] The viewing window 33 can be made of transparent materials such as glass. A window can be pre-opened on the opening frame 32 and then covered by the viewing window 33. The covered area can be sealed and fixed by adhesive or other means.

[0026] When the telescopic actuator 31 operates to press the annular sealing gasket 34 against the smooth surface of the test plate 2, a sealed cavity is formed between the opening frame 32 and the test plate 2.

[0027] A telescopic actuator 31 is installed at the top of the bracket 1, with its output end pointing vertically downwards. The opening of the opening frame 32 faces downwards and is fixed to the telescopic actuator 31, allowing for height adjustment of the opening frame 32. The test plate 2 is then placed on the bracket 1 for stable positioning. The telescopic actuator 31 then rotates, causing the opening frame 32 to move downwards and be pressed against the top of the test plate 2 by the annular sealing gasket 34, thus sealing the plate and forming a sealed cavity, improving testing efficiency. (Supplement: When the test plate 2 is a soft material, it should be placed on the bracket 1 for at least...) Figure 1 The ring-shaped support shown should be used, and it is best to perform a fine-pore sealing treatment at the position where the ring-shaped sealing gasket 34 is attached to the top of the test plate 2. The sealing treatment can be performed by spraying a rubber coating to increase the sealing performance.

[0028] It also includes an opening 4 on the opposite side of the bracket 1 on which the test plate 2 is placed. The opening 4 is connected to the test plate 2. As shown in the figure, an opening is set at the bottom of the test plate 2 to increase the exposure of the test plate 2 and increase the visible surface.

[0029] It also includes a water supply mechanism 5 fixed to the bracket 1 and the opening frame 32 for adding water to the sealed cavity, and a regulating valve 9 fixed to the opening frame 32. The regulating valve 9 is connected to the opening frame 32 and can be an electric ball valve or an electric butterfly valve.

[0030] The specific structure of the water supply unit 5 is shown below:

[0031] The water supply mechanism 5 includes a water pump 51 fixed on the bracket 1, an inlet pipe 52 with one end connected to the extraction end of the water pump 51, an inlet pipe 53 with one end connected to the discharge end of the water pump 51, and a first check valve 54 connected and installed between the inlet pipes 53. The other end of the inlet pipe 53 is fixedly inserted through the inner and outer sides of the opening frame 32. The water pump 51 can be a multi-stage pump (high precision), the first check valve 54 is a straight-through check valve, and the inlet pipe 53 is a flexible hose (made of plastic or other materials).

[0032] The water source (not shown in the figure) is connected to one end of the inlet pipe 52. When the water pump 51 is started, water can be pumped to the inlet pipe 53. The water flows through the first one-way valve 54 and then into the sealed cavity. There is a viewing window to observe the addition of an appropriate amount of water. The water volume should not be higher than the connection position between the inlet pipe 53 and the opening frame 32. When adding water, the regulating valve 9 is opened to release air and reduce the pressure on the pump.

[0033] It also includes a pressurizing mechanism 6 fixed on the bracket 1 and the opening frame 32 for pressurizing the gas supply in the sealed cavity, and a pressure sensor 7 fixed on the opening frame 32. The sensing end of the pressure sensor 7 is connected to the opening frame 32. The pressure sensor 7 can be a gas pressure sensor or a pressure transmitter, etc. The model of the pressure transmitter can be: MIK-PX300, etc.

[0034] The specific structure of the pressurization mechanism 6 is shown below:

[0035] The pressurization mechanism 6 includes a vacuum pump 61 fixed on the bracket 1, an air inlet pipe 62 with one end connected to the extraction end of the vacuum pump 61 and fixed, an air inlet pipe 63 with one end connected to the discharge end of the vacuum pump 61 and fixed, and a second one-way valve 64 connected and installed between the air inlet pipes 63. The other end of the air inlet pipe 63 is fixedly inserted through the inner and outer sides of the opening frame 32. The vacuum pump 61 can be a piston pump, the second one-way valve 64 is a straight-through one-way valve, and the air inlet pipe 63 is a flexible hose (made of plastic or other materials).

[0036] When the air pump 61 is started, suction is generated in the air inlet pipe 62, which draws air into the air inlet pipe 63. The airflow passes through the second one-way valve 64 and is then discharged into the sealed cavity, which pressurizes the sealed cavity and increases the pressure of the water on the test plate 2. The pressure sensor 7 can detect the pressure. When the pressure reaches a suitable value, the controller 8 shuts off the operation of the air pump 61. The amount of water added should not exceed the connection position between the air inlet pipe 63 and the opening frame 32.

[0037] It also includes a controller 8 fixed on the bracket 1. The controller 8 is a PLC controller that connects to an external power source to supply power to the electrical components and control their opening and closing (the pressure sensor 7 mentioned above is used to preset the pressure value and connect to the controller 8 to control its opening and closing).

[0038] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
