Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of thermal insulation and decoration performance testing, and particularly relates to a fixing device for a pull-out test of an integrated thermal insulation and decoration board. Background Technique
[0002] In the production and quality control process of the integrated thermal insulation and decoration board, there are significant technical problems in the traditional bonding pull-out test method for the integrated thermal insulation and decoration board. Specifically, this method mainly bonds the integrated thermal insulation and decoration board through two fixed iron sheets and fixes it on a pull-out testing machine for pull-out testing. The inefficiency of this method is mainly reflected in the following aspects: First, only one test block can be cold-pressed in each experiment, which means that each experiment requires waiting for the test block to be fully cured or reach the test conditions. Usually, this process takes 5 - 6 hours. This single-experiment method greatly limits the parallel processing ability of the experiment, thus significantly prolonging the overall experiment period. Second, according to the specification requirements, 6 pull-out experiments need to be carried out for each group of tests, and at least 4 of these 6 experiments must be damaged in the thermal insulation material to determine that the damage occurs in the thermal insulation material. This determination criterion itself increases the complexity and time-consuming of the experiment. Third, considering that each experiment takes 5 - 6 hours and 6 experiments need to be carried out, it takes at least 3 days to complete a complete set of pull-out experiments. Such an experiment period obviously cannot meet the supply cycle requirements for a workshop pursuing high efficiency.
[0003] Therefore, the traditional bonding pull-out test method for the integrated thermal insulation and decoration board is not only inefficient but also unable to meet the actual needs of workshop production, which has become an important technical problem faced currently. To solve this problem, new experimental methods and technical means need to be explored to improve the experimental efficiency and shorten the experimental period, so as to better meet the production requirements. Content of the Utility Model

[0026] In order to further elaborate on the technical solution of the present utility model, the following combines the attached Figures 1 to 4 , according to the on-site implementation and testing process, we further illustrate the technical solution protected by the present utility model through five embodiments. Embodiment 1
[0027] As shown in the attached Figure 1 A heat preservation and decoration integrated board drawing experiment test fixing device includes three parts: a bracket body, a pressing mechanism, and a counterweight.
[0028] I. Bracket body part: The first assembly connecting plate 1 is installed on the bottom plate 4 through the cushion block 3. Two columns 5 are arranged on the first assembly connecting plate 1. The second assembly connecting plate 2 is slidably arranged between the two columns 5 through the embedding grooves 17 on both sides. A counterweight hanging rod 9 is hinged on each column 5 through a pin 8. A first connection hole 10 is arranged on the counterweight hanging rod 9, and a suspension hole 11 is arranged on the counterweight hanging rod 9.
[0029] II. Pressing mechanism part: Two said second assembly connecting plates 2 are respectively fixed on both sides of the moving seat 12. Two connecting rods 13 are arranged on the moving seat 12, and a plurality of second connecting holes 14 are equidistantly arranged on the connecting rods 13.
[0030] III. Counterweight part: A hook rod 28 is arranged on the counterweight 25. The counterweight 25 is connected to the counterweight hanging rod 9 through the hook rod 28 embedded in the hanging hole 11 to provide the required pressing gravity according to the requirements of experimental specimens with different thicknesses.
[0031] As shown in the Figures 3 to 5 attachment. In this embodiment, after the finished product of the thermal insulation and decoration integrated board is offline, first, cut the test specimen 2702 for sampling in the first instance, and then use an adhesive to bond two cold-pressed adhesive iron sheets 2701 to the front and back panels of the test specimen 2702 to prepare the test piece 27. Then, assemble multiple groups of prepared test pieces 27 with bolts and nuts, and then install the assembled whole between the first assembly connecting plate 1 and the second assembly connecting plate 2 with bolts and nuts. Finally, the counterweight hanging rod 9 is connected to the connecting rod 13 by sequentially passing through the first connecting hole 10 and the second connecting hole 14 with the rotating screw 26, and counterweights 25 are hung at the ends of the two counterweight hanging rods 9 according to the requirements of pressing experimental specimens with different thicknesses to meet the requirements of the cold-pressed adhesive iron sheets and the test specimens. After the adhesive dries for 6 hours, take out the test piece 27, and connect the test piece 27 one by one on the pull-out testing machine through the fixing bolts, that is, the two cold-pressed adhesive iron sheets 2701 are connected and fixed with the fixing iron sheet 29 by bolts and nuts, and the two fixing iron sheets 29 are respectively connected to the upper cross beam and the lower cross beam of the pull-out testing machine by using the connecting bolts 30 thereon in cooperation with nuts. Start the pull-out testing machine to conduct the pull-out test for each piece and record the pull-out test data; ultimately, it achieves the effect of efficiently testing the pull-out test data. The pull-out test convenient fixing device for the thermal insulation and decoration integrated board can press at most 3 pieces each time. To meet the requirement of 6 pieces of test data in the specification, multiple devices can be reused for pressing and bonding the test specimens and the iron sheets.
[0032] It should be noted that two grooves 2703 are arranged on each said cold-pressed adhesive iron sheet 2701, which is convenient for the later test piece 27 to be embedded between the two columns 5 without affecting the pressing effect. Embodiment II
[0033] As shown in the Figure 1 attachment. In the pull-out test fixing device for the thermal insulation and decoration integrated board, a stop bar 16 is designed on each column 5. The main function of this stop bar 16 is to prevent the counterweight hanging rod 9 from being too close to the moving seat 12 during the pressing process, thus avoiding interference with the installation of the test piece 27. The setting of the stop bar 16 not only ensures the stability of the pressing process but also improves the operation convenience of the overall device. Embodiment III
[0034] As shown in the Figure 2 accompanying drawings, on the basis of Embodiment I, the front and rear sides of the moving seat 12 are optimized. Specifically, mounting holes 19 are respectively provided on the front and rear sides of the moving seat 12, and a pressing plate 21 is installed between these mounting holes 19 using a screw 20 and a nut 22. At the same time, springs 23 are also installed on each screw 20, and these springs 23 are located below the pressing plate 21. Such a design enables the pressing plate 21 to utilize the reverse acting forces of the two springs 23 to ensure good contact with the test piece 27, thereby further ensuring the pressing effect exerted by the counterweight 25. Embodiment IV
[0035] As shown in the Figure 2 accompanying drawings, two rollers 18 are provided on the second assembly connecting plate 2. These two rollers 18 are respectively located on both sides of the embedding groove 17 and keep rolling contact with the surface of the column 5. Such a design can effectively reduce the resistance generated by rigid contact during the pressing process, enabling the test piece 27 to better meet the pressing requirements, thereby improving the working efficiency and test accuracy. Embodiment V
[0036] As shown in the Figure 1 and 2 accompanying drawings, in order to further improve the structural stability of the overall device, in this embodiment, a structural enhancement design is carried out on the bracket body and the pressing mechanism part. First, a cross beam 6 is provided between the two columns 5 to increase the lateral stability of the overall structure. Secondly, inclined supports 7 are added between each column 5 and the bottom plate 4, which can effectively prevent the column 5 from deforming or tilting when subjected to pressure. Finally, a cross connecting plate 15 is fixed between the two connecting rods 13, and an inclined support rib plate 24 is provided between the moving seat 12 and the connecting rod 13 to enhance the structural stability of the connecting rod 13 and the moving seat 12. These improvement measures together enhance the overall stability and reliability of the device.
