Description

Technical Field

[0001] This utility model relates to the technical field of testing concrete waterproofing and densifying agents, and in particular to a device for testing the performance of concrete waterproofing and densifying agents. Background Technology

[0002] Concrete waterproofing and densifying agents can be added to concrete during mixing to improve overall performance, or used for crack repair to enhance localized waterproofing. The specific application method depends on the product type and project requirements. However, existing concrete waterproofing and densifying agent performance testing devices typically test waterproofing through natural immersion, which is too slow and slows down overall testing efficiency when dealing with a large number of samples in a single batch. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a concrete waterproofing and densifying agent performance testing device, which solves the technical problem of slow testing process and achieves the goal of improving testing efficiency.

[0004] To solve the above technical problems, the present invention provides the following technical solution: a concrete waterproofing and densifying agent performance testing device, including a weighing device as a supporting foundation, a storage chamber at the top of the weighing device, a water cover detection component for applying water to concrete bricks at the top of the storage chamber, and a concrete brick clamping component for clamping concrete bricks inside the storage chamber. The water immersion detection component includes a closed chamber rotatably connected to the top of the storage chamber. A water tank is installed on one side of the closed chamber via a base. A water pump is installed on the side of the closed chamber next to the water tank via a base. A one-way valve is connected to the middle of the bottom of the closed chamber. A water outlet pipe is connected to the middle of the closed chamber near the storage chamber. A sealed folding pipe is fixedly connected to the closed chamber near the storage chamber.

[0005] Preferably, the top end of the water outlet pipe is connected to the water outlet end of the one-way valve, and the length of the water outlet pipe is less than the length of the sealing folded pipe.

[0006] Preferably, both the outlet and inlet ends of the water pump are connected to connecting pipes, and the ends of the connecting pipes at the outlet and inlet ends of the water pump are respectively connected to a one-way valve and a water tank.

[0007] Preferably, the concrete brick clamping assembly includes two symmetrical clamping grooves formed at the bottom of the storage compartment, with concrete clamping blocks slidably connected to the inner side of the clamping grooves, and a bidirectional screw rotatably connected to the middle of the bottom of the storage compartment via a bracket.

[0008] Preferably, both concrete clamping blocks are helically connected to a bidirectional screw via threaded sleeves.

[0009] Preferably, the weighing device is equipped with a numerical display screen, and the signal input terminal of the numerical display screen is connected to the signal output terminal of the weighing device.

[0010] By employing the above technical solution, this utility model provides a device for testing the performance of concrete waterproofing and densifying agents, which has at least the following beneficial effects: 1. Due to the water immersion detection component, this utility model can apply high-pressure water flow to the surface of concrete bricks, weigh the total weight of the equipment plus the bricks, weigh the equipment minus the weight of the water-soaked concrete bricks, and then determine the weight of the water-bearing material on the bricks based on the original weight of the equipment. In this way, the water content absorbed by the concrete bricks can be determined, thus revealing the waterproofness.

[0011] 2. Due to the concrete brick clamping component, this utility model can clamp and fix the concrete bricks, thereby preventing the bricks from shifting during the operation of the water immersion detection component, which would affect the final detection results. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Existing concrete waterproofing and densifying agent performance testing devices typically test waterproofing performance through natural penetration. However, this method is too slow, hindering overall testing efficiency when dealing with large batches of samples. Please refer to... Figures 1-4 This embodiment provides a concrete waterproofing and densifying agent performance testing device, solving the technical problem of slow testing process. The device includes a weighing instrument 1 as a supporting foundation, a storage chamber 3 at the top of the weighing instrument 1, a water cover detection component 4 for applying water to concrete bricks at the top of the storage chamber 3, and a concrete brick clamping component 5 for clamping the concrete bricks inside the storage chamber 3. The concrete bricks are clamped by the clamping component 5, and water is applied to the concrete bricks by the water cover detection component 4.

[0017] Existing concrete waterproofing and densifying agent performance testing devices typically test waterproofing through natural immersion. However, this method is too slow, hindering overall testing efficiency when dealing with large batches of samples. To address this issue, a water refill testing component 4 is proposed. The water refill testing component 4 includes a sealed chamber 41 rotatably connected to the top of the storage chamber 3. A water tank 42 is mounted on one side of the sealed chamber 41 via a base. A water pump 43 is mounted on the side of the sealed chamber 41 next to the water tank 42 via a base. A one-way valve 44 is connected to the bottom center of the sealed chamber 41. A water outlet pipe 46 is connected to the center of the sealed chamber 41 near the storage chamber 3. A sealed folded pipe 47 is fixedly connected to the end of the sealed chamber 41 near the storage chamber 3. Connecting pipes 45 are connected to both the water outlet and inlet ends of the water pump 43. The ends of the connecting pipes 45 at the water outlet and inlet ends of the water pump 43 are connected to the one-way valve 44 and the water tank 42, respectively.

[0018] To prevent the bottom of the sealed folded pipe 47 from contacting the concrete brick and shrinking, the outlet pipe 46 should not come into contact with the concrete brick surface. The top of the outlet pipe 46 is connected to the outlet of the one-way valve 44, and the length of the outlet pipe 46 is less than the length of the sealed folded pipe 47.

[0019] During testing, the operator places the concrete brick inside the concrete brick clamping assembly 5, then flips the sealed chamber 41. During this process, the bottom end of the sealing folded tube 47 fixedly connected to the sealed chamber 41 contacts the top surface of the concrete brick, thereby sealing the top surface of the concrete brick. Then, the water pump 43 is started to pump water from the water tank 42 into the outlet pipe 46, and then the water is delivered to the sealed folded tube 47 through the outlet pipe 46. As the water pump 43 pressurizes, the water will seep into the dry concrete brick. After a period of time, the water pump 43 pumps the water out of the sealed folded tube 47, and then the concrete brick is taken out and weighed separately. The weight of the concrete brick is compared with its weight when it is dry to determine whether it has absorbed water, thereby judging the waterproofness of the concrete.

[0020] Example 2 Based on Example 1, which solved the technical problem of slow detection process, the problem of concrete bricks not being able to be fixed still exists. Figures 1-4 As shown, the specific implementation process is as follows: In order to clamp and fix the concrete bricks, the concrete brick clamping assembly 5 includes two symmetrical clamping grooves 51 opened at the bottom of the storage chamber 3. Concrete clamping blocks 52 are slidably connected to the inner side of the clamping grooves 51. A bidirectional screw 53 is rotatably connected to the middle of the bottom of the storage chamber 3 through a bracket. Both concrete clamping blocks 52 are screwed to the bidirectional screw 53 through threaded sleeves. A numerical display screen 2 is installed on the weighing device 1. The signal input terminal of the numerical display screen 2 is connected to the signal output terminal of the weighing device 1.
