Description
The technical field is as follows:
the invention relates to the field of constructional engineering, in particular to a device and a method for testing toughness of a corner protection strip.
Background art:
with the rapid development of economy in China, the real estate market is vigorously developed and increasingly developed, a large number of corner protectors are required to be used in the home decoration process, but the corner protector market has no national and industrial standards for a long time, and the product quality cannot be qualitatively and quantitatively judged, so that the market is relatively disordered. The toughness of the angle bead is a key index for measuring the quality of the angle bead, other testing methods are complex, and the required speciality in the testing process is strong, so that the angle bead cannot be popularized and applied in a large range in actual operation.
The invention content is as follows:
the invention aims to overcome the defects and provide a device and a method for testing the toughness of the corner protector strip. The angle bead toughness testing device and the angle bead toughness testing method have the advantages of being simple in structure, simple to operate, convenient to use and the like, and enable consumers to evaluate and judge quality performance differences among different products more visually, quickly and accurately when purchasing angle beads.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the invention relates to a device for testing the toughness of a corner protection strip, which comprises:
angle bead test platform: the test platform is provided with at least one corner protection strip fixing structure;
the load-bearing structure is as follows: the bearing platform can move up and down, and the borne external force acts on the part of the corner bead extending out of the platform.
The angle bead toughness testing device is further optimized as follows:
the load bearing structure is connected with the external firmware and is guaranteed to translate up and down. The bearing structure keeps up-and-down translational motion, so that the angle bead can be stably and uniformly stressed, and the measuring result is more accurate.
The angle bead toughness testing device is further optimized as follows:
the distance between the load-bearing structure and the corner bead test platform is adjustable, and corresponding adjustment can be performed according to the length of the corner bead extending out of the outer portion of the platform, so that the test range is more universal.
The invention also relates to a method for testing the toughness of the angle bead by using the angle bead toughness testing device, which comprises the following steps:
A. cutting a section of angle bead strip with smooth surface and no crease, fixing one end of the angle bead strip on the test platform, and ensuring that the part of the other end of the angle bead strip extending out of the platform can reach the position of the bearing structure for testing;
B. translation bearing structure from top to bottom makes bearing structure press in the angle bead top that extends the platform outer part, through the weight or exert exogenic action, makes bearing structure push down the downward translation of angle bead, and when the displacement that the angle bead moved down reached the angle bead and extended 1/8 ~ 1/10 of platform outer part length, the time of stewing reaches 30 ~ 45 seconds, and the angle bead does not take place the breakage, and the numerical value that obtains at this moment of measurement is the toughness numerical value of angle bead promptly. When the displacement of the downward movement of the corner bead reaches 1/8-1/10 of the length of the corner bead extending out of the outer part of the platform, standing is carried out, because when the displacement reaches the displacement range, the range is usually the boundary range of qualified corner beads and unqualified corner beads, the test can be faster and more visual; the standing time is selected to be 30-45 seconds, because the downward movement of the corner protector strip is basically stable in the time range, the toughness of the corner protector strip can be accurately confirmed, the time is saved, the overlong time is not favorable for quickly evaluating the quality performance of the corner protector strip, and the influence of other factors can be caused to cause inaccurate results; and if the standing time is too short, the downward movement of the corner protecting strip is not stable, and the result is inaccurate.
Therefore, the correct reasonable selection angle bead extends the length of the platform outer part and the displacement distance that the angle bead moves down and the proportional relation with the length that the angle bead extends the platform outer part, and the length of the time of stewing, mainly can play 2 effects, firstly can test fast and distinguish qualified and unqualified product, secondly to qualified product, then can test qualitatively and quantitatively fast and distinguish that the quality performance of which angle bead product is better, and the test result is more directly perceived, more accurate, more is favorable to judging and choosing.
The method for testing the toughness of the corner bead is further optimized as follows:
the length of the corner bead extending out of the outer part of the platform is 30-60 cm.
The method for testing the toughness of the corner bead is further optimized as follows:
the length of the cut angle bead with smooth surface and no crease is 50-80 cm.
The device and the method for testing the toughness of the corner bead have the advantages of simple operation, accurate detection and the like, and operators do not need to have much professional skills. In addition, the device and the method for testing the toughness of the corner bead strip have the characteristic of wide application, and play an important role in standardizing the product quality of the corner bead strip. Under the condition of lacking national and industrial standards, the testing device and the testing method of the invention can enable consumers to more intuitively, quickly and accurately evaluate and judge the quality performance difference among different products when selecting and purchasing the corner protectors, and can play a key reference role in the future establishment of the national and industrial standards.
