Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering, and particularly relates to a construction parameter confirmation test device, method and system based on an electric demoulding technology. Background Art

[0002] When concrete is poured, if the electric demoulding technology is adopted, it is not necessary to apply any release agent on the steel formwork, and the concrete will not adhere to the steel formwork. This is particularly important for slip form projects where it is difficult to apply the release agent. For a long time, in slip form construction, due to continuous operation, it is difficult to apply the release agent to the formwork, and the concrete is more likely to adhere to the surface of the formwork, resulting in an increase in the side resistance of the formwork during sliding, poor appearance quality of the concrete after sliding out of the formwork, and even tiny cracks caused by the formwork being lifted and cracked, affecting the quality of the concrete.

[0003] A large number of tests and engineering practices have proved that the electric demoulding has the following advantages: (1) It eliminates the conventional practice of applying a release agent to the inner surface of the formwork before each concrete pouring, greatly saving manpower, material resources and time; (2) The surface of the concrete is not polluted after demoulding, which is beneficial to the next surface decoration work and also conducive to the cleaning of the formwork surface after construction; (3) The electric demoulding technology is particularly suitable for slip form construction projects where it is difficult to apply the release agent. It can not only reduce the friction between the formwork and the concrete to ensure the surface quality of the concrete, but also solve the problem of difficult cleaning of the formwork surface in slip form construction; (4) The concrete electric demoulding technology does not affect the conventional construction process, and has no adverse effects on the various properties of the concrete when the electric demoulding technology is adopted; (5) The electric demoulding device has a simple structure, is easy to operate, consumes less electric energy and has low construction costs.

[0004] However, there are no relevant research results on how to select the relevant technical parameters of electric demoulding and how to evaluate its demoulding effect. Through literature collection and on-site investigation, it is found that the electric demoulding technology has not been popularized and applied so far.

[0005] The main reasons are as follows: The electric demoulding technology is proposed based on the principles of electrolysis and electroosmosis, and the electrolysis and electroosmosis effects are affected by various factors such as electrode materials, the number of electrodes, electrode positions, arrangement forms, energization time, and dielectric materials. So far, there has been no research on the influence law of various factors on the construction effect of electric demoulding.

[0006] The construction environments, concrete materials, etc. of different projects are also different, so the applicable electrolysis and electroosmosis schemes are different. If a suitable electrolysis and electroosmosis scheme cannot be proposed, the application effects of the electric demoulding technology in different projects will be different. Summary of the Invention

[0007] The technical problem to be solved by the present invention is that the electric demoulding technology is less applied in actual projects. The purpose is to provide a construction parameter confirmation test device, method and system based on the electric demoulding technology, and solve the problem of how to select the relevant technical parameters of electric demoulding for different construction environments and concrete parameters.

[0065] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present invention.

[0066] In addition, it should also be noted that for the convenience of description, only the parts related to the present invention are shown in the drawings.

[0067] Without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0068] The electric demoulding technology solves the problem of the inability to apply release agent during the slip form construction process, reduces the adhesion between the concrete surface and the formwork, reduces the friction force of the formwork on the concrete during slip form, thereby reducing the tensile cracks on the concrete surface, improving the appearance quality of the slip form project, and also improving the durability of the concrete.

[0069] The basic principle of electric demoulding is based on electroosmosis and electrolysis. A metal electrode is inserted into the cast-in-place concrete as the anode, and the slip form metal formwork is used as the cathode. Under the action of a DC electric field, a water-vapor mixed layer is generated between the surface of the formwork (cathode) and the concrete. This mixed layer plays a role in isolating the concrete from the formwork, reducing the side friction resistance during formwork lifting, greatly reducing the phenomenon of concrete hairing and cracking, basically eliminating the need for defect treatment, improving the plastering rate, and thus shortening the construction period and reducing costs.

[0070] However, due to different construction environments for concrete pouring, different self-parameters of the concrete, and uncertain electrolysis-related parameters, the generation states of the water-vapor mixed layer are different. Therefore, if fixed electric demoulding parameters are used, the electric demoulding effect will be uncertain.

[0071] Embodiment 1

[0072] To address the above problems, this embodiment provides a construction parameter confirmation test device based on electric demoulding technology, including an outer mold, an inner mold, a lifting device, an electrode rod, and a power supply.

[0073] The outer mold is a cylindrical structure, and the central axis of the outer mold is vertically arranged. The outer mold is generally fixed, and its main purpose is to fix the concrete and prevent the unhardened concrete from overflowing.

[0074] The inner mold is a cylindrical structure arranged inside the outer mold. The inner mold and the outer mold are coaxially arranged. Concrete is poured between the outer mold and the inner mold. The outer mold and the inner mold form an annular structure, so that the poured concrete can solidify into a concrete ring. By changing the vertical position of the inner mold, the purpose of simulating demolding is achieved.

[0075] The lifting end of the lifting device is connected to the inner mold. The lifting device lifts the inner mold to move up and down along its central axis. The lifting device can be fixed on an existing hanging rack. Its main function is to install the inner mold and apply an upward force to the inner mold when simulating demolding is required.

[0076] The electrode rods are vertically fixed in the concrete between the outer mold and the inner mold. The positive pole of the power supply is electrically connected to the electrode rods, and the negative pole of the power supply is electrically connected to the inner mold.

[0077] The power supply provides direct current. The electro-activation plate and the inner mold are connected to the anode and the cathode to achieve the purpose of electrolysis.

[0078] Therefore, the inner mold and the electrode rods need to be set as conductors. And because only the inner mold is lifted to simulate demolding, only the contact surface between the concrete ring and the inner mold needs to be electrolyzed. Therefore, in order to avoid current shunting, it is set that there is insulation between the inner mold and the outer mold and between the lifting device and the inner mold.

[0079] To facilitate the installation of the outer mold and the inner mold, the outer mold also includes a bottom plate. A positioning block coaxial with the outer mold is arranged on the bottom plate. The inner mold contacts the positioning block and is coaxially arranged with the outer mold through the positioning block.

[0080] The following provides a reference dimension relationship:

[0081] For the inner mold, D = 50 cm. For the outer mold, D = 150 cm. The electrode rods are copper rods with a selected diameter of 10 mm. The copper rods are connected by copper wires and connected to the positive pole of the power supply. The power supply uses an electrolytic demolding technology electrolyzer (electroforming device) to provide a DC regulated power supply. Its output voltage is 0 - 36 V, and the output current is 1 - 15 A (DC); the working voltage < 36 V, which is a safe voltage and will not cause safety hazards, and can meet the needs of conventional construction.

[0082] Embodiment 2

[0083] This embodiment provides a construction parameter confirmation test method based on an electro-demolding technology for a construction parameter confirmation test device based on the electro-demolding technology in Embodiment 1, including the following steps:

[0084] S1. Set variables. Variable 1: Electrode position; The electrode position is the distance between the electrode rod and the outer side surface of the inner mold;

[0085] Variable 2: Electrode spacing; The electrode spacing is the distance between two adjacent electrode rods;

[0086] Variable 3: Power-on time; the power-on time is the time when the electrode rod and the inner mold are connected to the power supply.

[0087] S2. Under the condition of ensuring that the test environment is the same as the construction environment, install the outer mold, inner mold and lifting device, and make the inner mold and the outer mold coaxial; the test environment and the construction environment can always ensure that the relevant parameters of the concrete in actual construction are the same as those in the test, so that the test has usability.

[0088] S3. Determine the lifting time according to the test environment and the concrete to be tested. The lifting time is the time interval between the completion of concrete vibration and the lifting of the inner mold; according to experience, under the premise that the poured concrete can maintain its shape, the earlier the demolding, the easier it is. Therefore, under the condition of fixed test environment and fixed concrete parameters, the lifting time can be known, and it is generally a fixed value.

[0089] S4. Set the value of variable 1 to A, the iterative value of variable 1 to a, the value of variable 2 to B, the iterative value of variable 2 to b; the value of variable 3 to C, and the iterative value of variable 3 to c;

[0090] It can be set according to the test requirements. In this embodiment, a specific implementation parameter is provided: A = 10 cm, a = cm, B = 36 cm, b = 5 cm, C = 30 min, c = 30 min.

[0091] S5. Let A = A + a, B = B + b, iterate A m - 1 times, iterate B n - 1 times, and output the test structures corresponding to m × n test devices;

[0092] According to practical experience, according to the thickness and related parameters of the concrete, it can be set that: m = 3, n = 3, that is, both A and B are iterated 3 times. That is, the values of A are 10 cm, 15 cm, and 20 cm, and the values of B are 36 cm, 41 cm, and 46 cm. By corresponding A and B, 9 test structures can be obtained.

[0093] S6. Pour the concrete between the outer mold and the inner mold, and install the electrode rod according to one of the test structures in step S5; select 1 from 9 for the test structure, and multiple tests are not repeated.

[0094] S7. Electrically connect the power supply to the electrode rod and the inner mold; set the power-on voltage to a fixed value of 30 V.

[0095] S8. Let C = C + c, iterate C i - 1 times, and output m × n × i test results;

[0096] According to the actual parameters, set i = 3, and the values of C are 30 min, 60 min, and 90 min.

[0097] S9. Select the combination of A, B, and C corresponding to the test structure with the minimum lifting force or the best smoothness from the m×n×i test results.

[0098] Conduct 3 tests on each test structure, finally obtain 27 test structures, and select the result with the minimum lifting force or the best smoothness from the 27 test results as the output result.

[0099] Alternatively, according to the actual situation, a compromise solution can be selected, that is, select the solution with the minimum lifting force under the condition of meeting the smoothness.

[0100] Example 3

[0101] This example is an optimization of step S8 in Example 2, and the specific steps are as follows:

[0102] Select an untried test structure from the 9 test structures and install the electrode rods according to the test structure;

[0103] Pour concrete with a height of h;

[0104] Apply power. When the power-on time C = C, stop applying power and wait for the lifting time;

[0105] Control the lifting device to lift the inner mold and the electrode rods by h, and obtain the lifting force of the lifting device and the smoothness of the inner side surface of the concrete ring;

[0106] Continue to pour concrete with a height of h above the concrete ring poured in the previous step;

[0107] Apply power. When the power-on time C = C + c, stop applying power and wait for the lifting time;

[0108] Control the lifting device to continue to lift the inner mold and the electrode rods by h, and obtain the lifting force of the lifting device and the smoothness of the inner side surface of the concrete ring;

[0109] Iterate on the number of concrete layers and C for i - 1 times, output i test results, and the maximum power-on time is not greater than the lifting time.

[0110] Return to step S6, change the untried test structure, and output i test results;

[0111] Repeat the above steps m×n times, and finally output m×n×i test results.

[0112] Example 4

[0113] Before performing the methods of Example 2 and Example 3, set a pre-step, and its method includes:

[0114] Pour the concrete between the outer mold and the inner mold;

[0115] After waiting for the lifting time, lift the inner mold by h;

[0116] Obtain the lifting force F0 of the lifting device and the smoothness of the inner side of the concrete ring.

[0117] That is, obtain the relevant parameters for demolding without electric demolding.

[0118] Compare with the test results of Example 2 and Example 3, and the following results can be obtained.

[0119] Effect of energization time:

[0120] When the electrode distance is 10 cm and the energization time is 30 min, the side friction resistance (lifting force - inner mold gravity) is 344 N. When the energization time is 60 min and 90 min, the side friction resistance increases by 336.63% and 598.55% respectively. When not energized, the side friction resistance is 2876 N, an increase of 736.05%.

[0121] When the electrode distance is 15 cm and the energization time is 30 min, the side friction resistance is 668 N. When the energization time is 60 min and 90 min, the side friction resistance increases by 8.68% and 19.46% respectively. When not energized, the side friction resistance is 2876 N, an increase of 330.54%.

[0122] When the electrode distance is 20 cm and the energization time is 30 min, the side friction resistance is 967 N. When the energization time is 60 min and 90 min, the side friction resistance increases by 22.64% and 39.19% respectively. When not energized, the side friction resistance is 2876 N, an increase of 197.41%.

[0123] In addition, by comparing with the non-energized situation, it is found that regardless of the length of the energization time and the distance of the electrode position, the side friction resistance of the lifting formwork is less than that in the non-energized situation, indicating that energization has a great influence on reducing the side friction resistance. Therefore, during the slip form construction process, electric demolding technology should be adopted to increase the lubrication between the concrete formworks and reduce the side friction resistance, and the energization time should not be too long, preferably less than 30 min.

[0124] Effect of electrode position:

[0125] When the energization time is 30 min, as the electrode distance increases, the side friction resistance increases. The side friction resistance in the case of an electrode position of 15 cm increases by 94% compared with the case of an electrode position of 10 cm;

[0126] The side friction resistance in the case of an electrode position of 20 cm increases by 181.10% compared with the side friction resistance in the case of an electrode position of 10 cm.

[0127] When the power-on time is 60 min, the side friction resistance in the case of the electrode position being 15 cm is reduced by 21% compared with the case of the electrode position being 10 cm, and the side friction resistance in the case of the electrode position being 20 cm is reduced by 51.66% compared with the case of the electrode position being 10 cm.

[0128] When the power-on time is 90 min, the side friction resistance in the case of the electrode position being 15 cm is reduced by 21% compared with the case of the electrode position being 10 cm, and the side friction resistance in the case of the electrode position being 20 cm is reduced by 51.66% compared with the case of the electrode position being 10 cm.

[0129] It can be seen that the smaller the electrode position, the smaller the side friction resistance; when the power-on time is 30 min, therefore, in engineering applications, it is recommended that the electrode position be taken about 10 cm.

[0130] Influence of electrode spacing:

[0131] Regardless of the number of electrodes, the side friction resistance between the concrete and the formwork can be reduced after power-on. In addition, with the increase in the number of electrodes, the side friction resistance decreases.

[0132] Under the action of 1 electrode, the side friction resistance is reduced by 55.98% compared with the non-powered case. Under the action of two electrodes, the side friction resistance is reduced by 64.22%. Under the action of three electrodes, it is reduced by 69.33%. It can be seen that when the electrode position is certain, the more the number of electrodes, the better the demoulding effect, but with the increase in the number, the percentage reduction of the side friction resistance gradually decreases. Therefore, in actual engineering applications, it is recommended to determine the number of anodes according to the actual engineering situation.

[0133] Example Five

[0134] Before carrying out Example Two, a debugging step is also required. The main purposes of carrying out the electrolyzed water test include two. One is to verify the phenomenon of H2 and O2 generated by the electrolysis of water; the other is to debug the instrument and equipment to ensure the normal operation of equipment such as the power supply, electrodes, and wires.

[0135] The methods of the debugging step include:

[0136] Seal the lower end of the inner formwork and the installation surface, and the lower end of the outer formwork and the installation surface;

[0137] Inject clean water between the inner formwork and the outer formwork;

[0138] Electrically connect the power supply to the electrode rod and the inner formwork;

[0139] Judge whether there are bubbles at the electrode rod and whether there are bubbles on the outer side of the inner formwork. If one of them is no, it proves that the test device is faulty; if both are yes, then judge the amount of bubbles;

[0140] If the amount of bubbles at the electrode rod is less than that on the outer side of the inner mold, it proves that the test device is normal; if the amount of bubbles at the electrode rod is greater than that on the outer side of the inner mold, it proves that the test device is faulty.

[0141] When the electrode is placed in water and powered on for five minutes, uniform fine bubbles can be seen around the electrode rod, gradually rising upwards and concentrating on the water surface, and a large number of bubbles concentrate on the outer side of the inner mold. It can be analyzed that the OH- ions in the water are attracted to the anode and move towards the anode, and a discharge reaction occurs to generate O2; the H+ is attracted to the cathode and moves towards the cathode, and accepts electrons at the cathode to generate H2. In addition, it can be seen that there are more bubbles at the cathode than at the anode. The main reason is that the H2 generated by the electrolysis of water is basically twice that of O2, and O2 is soluble in water. Therefore, part of the gas generated at the anode is also dissolved in water, resulting in very few bubbles at the anode and more bubbles at the cathode.
