Abstract
Description
Technical Field
[0001] This application relates to the technical field of building materials, and in particular to an auxiliary device for testing rust-inhibiting performance. Background Technology
[0002] Reinforced concrete is one of the main building materials, and corrosion of the reinforcing steel in reinforced concrete structures can lead to durability failure. Corrosion inhibitors for reinforcing steel are chemical substances added to concrete or applied to the concrete surface that can prevent or slow down the corrosion of the reinforcing steel.
[0003] To ensure the correct use of qualified steel reinforcement corrosion inhibitors and guarantee the quality and safety of reinforced concrete buildings, it is necessary to test the corrosion inhibition performance of steel reinforcement corrosion inhibitors. Currently, the percentage of steel reinforcement corrosion area in a salt water wet-dry cycle environment test in JT / T 537 is a commonly used method for testing corrosion inhibition performance. However, this method requires a large number of test blocks and cycles, frequent handling of steel reinforcement specimens, which is time-consuming. Furthermore, direct clamping and gripping can easily damage the surface of the steel reinforcement, leading to errors in the experimental results. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide an auxiliary device for rust inhibition performance testing, addressing the aforementioned problems.
[0005] The embodiments of this application are implemented as follows:
[0006] This application provides an auxiliary device for a rust-inhibiting performance testing experiment, characterized in that it includes a base plate, on which a plurality of steel bar specimen positioning holes are formed, and steel bar specimen fixing members are provided in the steel bar specimen positioning holes, and the steel bar specimens are positioned by passing through the steel bar specimen positioning holes and being fixed by the steel bar specimen fixing members.
[0007] In some optional embodiments, the steel bar specimen fixing member is a plurality of soft toothed blocks evenly spaced along the circumference of the positioning hole of the steel bar specimen, and the soft toothed blocks extend outward on the side facing the positioning hole of the steel bar specimen.
[0008] In some alternative implementations, the thickness of the soft toothed block decreases from the inside out, forming a block with a trapezoidal cross-section.
[0009] In some alternative implementations, the soft toothed blocks are inclined inward and tighten from the inside out, with the tops of multiple soft toothed blocks forming circular holes with an inner diameter smaller than the diameter of the positioning holes of the reinforcing bar specimen.
[0010] In some alternative embodiments, the substrate is a triangular plate structure, and the steel bar specimen has three positioning holes, corresponding to the three tips of the substrate.
[0011] In some alternative embodiments, a lifting ring is provided on one side of the substrate to facilitate the placement and removal of the substrate.
[0012] In some alternative implementations, the diameter of the positioning hole for the reinforcing bar specimen is the same as the diameter of the reinforcing bar specimen.
[0013] In some alternative implementations, the soft tooth block is made of rubber material.
[0014] The beneficial effects of this application are: the auxiliary device provided by this application for the rust inhibition performance testing experiment can pick up and put down multiple steel bar specimens at one time, saving test time, and the auxiliary device will not contact the test surface of the steel bar specimens, avoiding damage, thereby reducing the error of the test results.

[0021] The features and performance of this application will be further described in detail below with reference to the embodiments.
[0022] like Figure 1 , Figure 2 As shown, an auxiliary device for rust inhibition performance testing includes a base plate 1, on which a plurality of steel bar specimen positioning holes 2 are formed. Steel bar specimen fixing members are provided in the steel bar specimen positioning holes, and the steel bar specimens are positioned by passing through the steel bar specimen positioning holes and being fixed by the steel bar specimen fixing members.
[0023] The diameter of the positioning hole for the reinforcing bar specimen is the same as the diameter of the reinforcing bar specimen, which facilitates the reinforcing bar specimen to pass through the substrate and is limited by the positioning hole.
[0024] Example 1
[0025] In this embodiment, the steel bar specimen fixing component consists of multiple soft toothed blocks 3 evenly spaced along the circumference of the positioning hole of the steel bar specimen. The soft toothed blocks can be made of rubber material and extend outward from the side facing the positioning hole of the steel bar specimen.
[0026] The thickness of the soft toothed blocks decreases from the inside to the outside, forming a block with a trapezoidal cross-section. At the same time, the soft toothed blocks are inclined inward and tighten from the inside to the outside. The tops of multiple soft toothed blocks form circular holes with an inner diameter smaller than the positioning hole diameter of the steel bar specimen.
[0027] The steel bar specimen passes through the positioning hole of the steel bar specimen, and the soft toothed block gradually tightens inward, generating pressure to fix the steel bar specimen for the experiment; the soft toothed block contacts the test surface of the steel bar specimen, avoiding damage and reducing experimental error.
[0028] Example 2
[0029] In this embodiment, the substrate is a triangular plate structure, and there are three positioning holes for the steel bar specimen, which are set corresponding to the three tips of the substrate.
[0030] The substrate can be a plate of other shapes, and the positioning holes of the steel bar specimens can also exceed three. In the above embodiment, the three steel bar specimens on the triangular substrate are adapted to the experiment of three steel bar specimens per group.
[0031] A lifting ring 4 is provided on one side of the substrate to facilitate the placement and removal of the substrate.
[0032] When using it, first press the treated steel bar specimen into the steel bar specimen positioning hole to ensure that the steel bar specimen fixing part can fix the steel bar specimen. Then, use the lifting ring to put the substrate in the salt solution and desiccator.
[0033] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments.
