Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to a water-repellent effect tester for emulsion-type nano-silica crack-resistant and seepage-reducing agents. Background Technology

[0002] Emulsion-type nano-silica crack-resistant and seepage-reducing agents are added to concrete to improve its water-repellent properties and prevent water from eroding the concrete through cracks.

[0003] In testing the water-repellent effect of emulsion-type nano-silica crack-resistant and seepage-reducing agents, a concrete block containing the agent was first broken using a machine to create a natural fracture surface, simulating cracks in actual concrete use. Then, the testing personnel held the broken concrete block with the fracture surface facing upwards and used a straw to drop water onto a relatively flat area of ​​the fracture surface. The testing personnel judged the water-repellent effect of the emulsion-type nano-silica crack-resistant and seepage-reducing agent by observing the water penetration through the fracture surface.

[0004] However, because the concrete block is handled by hand, the technician's hand is prone to rotation during the process, which can cause the fracture surface to tilt. This allows water droplets that fall on the fracture surface to easily roll to other areas of the fracture. As the water droplets roll, the contact area between the water droplets and the fracture surface increases, making it impossible to know the water-repellent effect of the fracture surface per unit area. Consequently, it is impossible for the testing personnel to effectively judge the water-repellent effect of the emulsion-type nano-silica crack-resistant and seepage-reducing agent. Utility Model Content

[0005] This application provides a water-repellent effect tester for emulsion-type nano-silica crack-resistant and seepage-reducing agents. By fixing the concrete block and ensuring that the fracture surface is in a horizontal state, the accuracy of the water-repellent effect test of the seepage-reducing agent is improved.

[0006] The water-repellent effect tester for an emulsion-type nano-silica crack-resistant and seepage-reducing agent provided in this application adopts the following technical solution:

[0007] A water-repellent effect tester for an emulsion-type nano-silica crack-resistant and seepage-reducing agent includes a base, on which a placement plate and an adjustment plate are provided, with the adjustment plate located above the placement plate; the placement plate is used to place a concrete block, and the adjustment plate is provided with multiple pressing parts, which are used to press the concrete block against the placement plate so that the fracture surface on the concrete block is in a horizontal state; the adjustment plate is provided with a clearance groove, which is located between the multiple pressing parts.

[0008] By adopting the above technical solution, the concrete block is pressed against the placement plate using the pressure part, so that the fracture surface of the concrete block is in a horizontal state when the water drip test is performed, thereby improving the accuracy of the water repellency test results of the seepage reducing agent.

[0009] Preferably, the base is threaded with four columns, each of the four columns has a threaded post at its top, and the adjustment plate has four clearance holes at its four corners. The four threaded posts are respectively inserted into the four clearance holes, and each of the four threaded posts is connected with a nut. The four nuts press the adjustment plate against the four columns.

[0010] By adopting the above technical solution, the adjustment plate can be detached, which makes it easy to carry the testing instrument and take it to the engineering site for use.

[0011] Preferably, there are four pressing parts, all of which are bolts threaded onto the adjusting plate, and the four bolts press against the four corners of the fracture surface of the concrete block respectively.

[0012] By adopting the above technical solution, the fracture surface may be uneven. When the bolt is used as a pressure-bearing part, the position of the bolt can be adjusted at will. This can effectively solve the problem of difficulty in pressure-bearing caused by the unevenness of the fracture surface and ensure the fixing effect of the concrete block during testing.

[0013] Preferably, the adjusting plate has multiple threaded holes arranged around the clearance groove, and four bolts are threaded into the corresponding threaded holes.

[0014] By adopting the above technical solution, concrete blocks of different sizes can be pressed and fixed.

[0015] Preferably, four springs are provided between the base and the placement plate, and both ends of the four springs are connected to the base and the placement plate.

[0016] By adopting the above technical solution, since the fracture surface is a natural surface, the fracture surface may be inclined, which allows the concrete block to tilt when the bolt presses against it, thereby keeping the fracture plane horizontal and ensuring the horizontality of the fracture surface while fixing the concrete block.

[0017] Preferably, a first limiting hole is provided on each of the four corners of the placement plate, and a second limiting hole is provided on each of the four corners of the base. The four first limiting holes are respectively aligned with the four second limiting holes. One end of each of the four springs is inserted into the four first limiting holes, and the other end of each of the four springs is located in the four second limiting holes.

[0018] By adopting the above technical solution, the installation and disassembly of the four springs and the placement plate are facilitated.

[0019] Preferably, the adjustment plate has a slot one, the base has a slot two, the slot one is directly opposite the slot two, a back plate is inserted into the slot one, and the bottom of the back plate is inserted into the slot two; the back plate has multiple horizontal lines, and the multiple horizontal lines are arranged on the back plate along the height direction of the back plate.

[0020] By adopting the above technical solution, a better standard can be provided for leveling the fracture surface.

[0021] Preferably, the placement plate has a receiving groove located below the clearance groove. The receiving groove is used to receive concrete blocks, and an elastic rubber pad is provided inside the receiving groove.

[0022] By adopting the above technical solution, the concrete block can be better fixed, and the elastic rubber pad is set to increase friction and better ensure the stability of the concrete block when it is pressed.

[0023] The main technical effects of this utility model are reflected in the following aspects:

[0024] 1. This utility model improves the accuracy of water-repellent effect testing of seepage-reducing agents by fixing concrete blocks;

[0025] 2. This utility model uses four bolts to fix the concrete block. By tightening the four bolts, the tilt of the concrete can be adjusted so that the fracture surface is in a horizontal state, which facilitates water dripping.

[0026] 3. This utility model is characterized by its ease of assembly and disassembly. Attached Figure Description

Detailed Implementation

[0032] The present application will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present application can be more easily understood and mastered.

[0033] Reference Figure 1 and Figure 2 This embodiment of a water-repellent effect tester for an emulsion-type nano-silica crack-resistant and seepage-reducing agent includes a base 1, on which four columns 5 are threadedly connected, and an adjusting plate 3 is placed. Each of the four columns 5 has a threaded post 51 integrally formed at its top. The adjusting plate 3 has four clearance holes 32 at its four corners, and the four threaded posts 51 are respectively inserted into the four clearance holes 32. Nuts 52 are connected to each of the four threaded posts 51, and the four nuts 52 fix the adjusting plate 3 to the four columns 5.

[0034] Reference Figure 1 and Figure 3 The base 1 also has four second limiting holes 11, each containing a spring 6, and a placement plate 2 is placed on each of the four springs 6. The placement plate 2 is located between the base 1 and the adjusting plate 3. The side of the placement plate 2 facing the base 1 has four first limiting holes 21, and the tops of the four springs 6 are inserted into these holes. The side of the placement plate 2 facing the adjusting plate 3 has a receiving groove 22 for accommodating concrete blocks. An elastic rubber pad 23 is placed inside the receiving groove 22.

[0035] Reference Figure 1 and Figure 3 The adjusting plate 3 has four pressing parts 4, which are used to press the concrete block against the placement plate 2, so that the fracture surface of the concrete block is in a horizontal state. The adjusting plate 3 has eight threaded holes 33, and the four pressing parts 4 are bolts 41 that mate with the threaded holes 33. The four bolts 41 press against the four corners of the fracture surface of the concrete block. The adjusting plate 3 also has a relief groove 31, which is located between the four bolts 41 and above the receiving groove 22.

[0036] Reference Figure 4 The adjustment plate 3 has a slot 34, and the base 1 has a slot 12. The slot 34 is directly opposite the slot 12. The back plate 7 is inserted into the slot 34, and the bottom of the back plate 7 is inserted into the slot 12. The back plate 7 has multiple horizontal lines 71, which are arranged along the height of the back plate 7.

[0037] The testing steps for this application's testing organization are as follows:

[0038] First, place the concrete block that will be broken by the machine into the receiving groove 22, so that the fracture surface faces the clearance groove 31. Then, screw the four bolts 41 into the threaded holes 33 in the appropriate positions, so that the four bolts 41 press against the fracture surface to fix the concrete block. At the same time, adjust the tilt of the concrete block so that the fracture surface is as flush as possible with the horizontal line 71 on the back plate 7.

[0039] Then, the tester passed the test tube through the relief groove 31 and dropped water droplets onto a relatively flat area of ​​the fracture surface. The tester then observed the absorption of the water droplets by the fracture surface to determine the water-repellent effect of the emulsion-type nano-silicon anti-crack and seepage-reducing agent.

[0040] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
