Description

[0001] The utility model relates to the technical field of detecting the deformation degree of a supporting keel and a plate to be tested when the plate to be tested bears a uniform load, in particular to a simulation test device for the deformation degree of a plate to be tested under a uniform load. Background Art

[0002] Currently, in many application scenarios of board materials, such as floor slabs, it is necessary to conduct a uniform load test on the board materials. In the past, weights were generally piled on the board materials to simulate the board materials bearing a uniform load. Although there were many weights, the weights were essentially a concentrated load, and the load distributed on the board surface was not uniform enough, making it impossible to fully and accurately simulate the uniform load borne by the board materials. Therefore, based on the above technical problems, this application proposes a convenient, intuitive, and reliable simulation test device for the degree of deformation of board materials under uniform load. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a simulation test device for the uniform load deformation degree of a plate, which is easy to operate and has reliable results.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a simulation test device for the degree of uniform load deformation of a plate, which is characterized by comprising a bracket, at least two supporting keels and at least one load water tank filled with water, wherein the supporting keels are parallel to each other and are placed across the top surface of the bracket, and the opposite sides of the top surface of the bracket are formed with guide grooves extending perpendicular to the cross-span direction of the supporting keels, and the two ends of each supporting keel are provided with spacing adjustment components respectively connected to the two guide grooves on the opposite sides; a preset plate to be tested is placed on each supporting keel, and the load water tank is pressed on the top surface of the plate to be tested, wherein the amount of water in the load water tank is proportional to the required load value.

[0005] Furthermore, a guide groove is formed at the edge positions around the top surface of the bracket, wherein the two guide grooves between adjacent edges are arranged perpendicularly, and the two guide grooves between opposite edges are parallel.

[0006] Furthermore, a support member is provided between the bracket and the load water tank, and the support member includes a support surface for preventing the load water tank from tipping over and a fixing surface fixed to the bracket; the support surface is inserted into the side of the load water tank; a through fixing hole is formed on the fixing surface; relatively parallel sliding grooves are formed on both sides of the outer side surface of the bracket, and the fixing holes and the sliding grooves are provided with limit bolts connected with bolts.

[0007] Furthermore, the supporting keel and the supporting member are arranged colinearly.

[0008] Furthermore, the load water tank is provided with a marking scale for indicating the water level height.

[0009] Furthermore, when the water level indicated by the marked scale is converted into a uniformly distributed load value, the uniformly distributed load value applied by the load water tank increases by 0.1 kPa for every 10 mm increase in the water level.

[0010] Furthermore, a plate sensor piece for detecting the deformation value of the plate to be tested is provided at the bottom of the plate to be tested; and a support keel sensor piece for detecting the deformation value of the support keel is provided at the bottom of the support keel.

[0011] The present invention adopts the above solution, and its beneficial effects are:

[0012] Reliability: By improving and optimizing the way of applying load to the test plate and supporting keel, the amount of water loaded into the water tank is converted into the load applied to the test plate. By controlling the water volume in the load water tank, the uniform load applied to the test plate and supporting keel is adjusted, thereby achieving more accurate testing of the test plate and supporting keel and ensuring more reliable test conclusions.

[0013] Safety: By setting supports on the bracket and inserting the supports into the side of the load water tank, the displacement of the load water tank is relatively limited, thereby preventing the load water tank from tipping over during operation and ensuring the safety of the test.

[0014] Applicability: According to the size of the tested plate, by increasing or decreasing the number of supporting keels, adjusting the placement position of the supporting keels and the spacing between the supporting keels, corresponding load tests can be performed on the tested plates of various sizes, which has a wider range of applicability.

DETAILED DESCRIPTION

[0020] To facilitate understanding of the present invention, a more comprehensive description of the present invention is provided below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided solely to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0021] See attached Figure 1 As shown, in this embodiment, a simulation test device for the uniform load deformation degree of a plate includes a support keel 1 for testing and a plate 2 to be tested, wherein the device is characterized in that it includes a bracket 4, at least two, preferably five support keels 1 and at least one, preferably four load water tanks 3 filled with water, wherein the support keels 1 are parallel to each other and are placed across the top surface of the bracket 4, and the opposite sides of the top surface of the bracket 4 are formed with guide grooves 41 extending perpendicular to the cross direction of the support keel 1, and the two ends of each support keel 1 are provided with spacing adjustment members 43 respectively connected to the two guide grooves 41 on the opposite sides. According to the size of the plate 2 to be tested, the spacing adjustment members 43 are adjusted by the guide grooves 41 on the opposite sides. The spacing adjustment component 43 adjusts the relative position of the supporting keel 1 on the slide groove 42 of the bracket 4 and the relative distance between the supporting keels 1 used, so that the subsequent test plate 2 can be placed on the supported supporting keels 1; the preset test plates 2 are placed on each supporting keel 1, and the load water tank 3 is pressed on the top surface of the test plate 2, wherein the amount of water in the load water tank 3 is proportional to the required load value, and the amount of water loaded into the water tank is converted into the load applied to the test plate 2, so that the load water tank 3 applies a uniform load to the test plate 2, and the supporting keel 1 supports the test plate 2 to bear the uniform load, thereby realizing the test of the test plate 2 bearing the uniform load.

[0022] For further information, see Appendix Figure 1 As shown, a guide groove 41 is formed at the edge positions around the top surface of the bracket 4, wherein the two guide grooves 41 between adjacent edges are arranged perpendicularly, and the two guide grooves 41 between opposite edges are parallel. According to the size of the supporting keel used, the guide grooves 41 on the opposite edges of the bracket 4 are selected, thereby increasing the applicability of the simulation test device for the degree of uniform load deformation of the plate.

[0023] In this embodiment, at least four, preferably ten support members 5 are provided between the bracket 4 and the load water tank 3. The support member 5 includes a support surface 51 for preventing the load water tank 3 from tipping over and a fixing surface 52 fixed to the bracket 4; the support surface 51 is inserted into the side of the load water tank 3, and the support surface 51 inserted into the side of the water tank is used to limit the relative displacement of the load water tank 3, thereby ensuring that the force area of ​​the load water tank 3 to the plate 2 to be tested remains unchanged; a through fixing hole 53 is formed on the fixing surface 52; relatively parallel slide grooves 42 are formed on the opposite sides of the outer side surface of the bracket 4, and the fixing hole 53 and the slide groove 42 are provided with limit bolts 54 bolted together, and the support member 5 is connected and fixed to the bracket 4 by the limit bolts 54, thereby ensuring the reliability of the test.

[0024] For further information, see Appendix Figure 3 As shown, the support keel 1 and the support member 5 are arranged in a collinear manner. By arranging the support keel 1 and the support member 5 in a collinear manner, the support member 5 fixed to the bracket 4 cooperates with the load water tank 3 to press the plate to be tested 2 and the support keel 1, making the placement of the plate to be tested 2 and the support keel 1 on the bracket 4 more stable, thereby increasing the accuracy of the test.

[0025] In this embodiment, see the attached Figure 3 As shown, the load water tank 3 is provided with a marking scale 31 for indicating the water level height, wherein the water level height of the load water tank 3 is proportional to the water pressure value (i.e., the uniformly distributed load value). According to the uniformly distributed load required for the test, the water level height is adjusted by observing the marking scale 31 on the water tank, so as to adjust the uniformly distributed load applied to the plate 2 to be tested and the supporting keel 1.

[0026] Furthermore, when the water level height indicated by the marked scale 31 is converted into a uniformly distributed load value, the uniformly distributed load value applied by the load water tank 3 increases by 0.1 kPa for every 10 mm increase in the water level. Through the conversion relationship between the marked scale 31 and the uniformly distributed load value, the uniformly distributed load value borne by the plate 2 to be tested can be directly read when the water volume is loaded, thereby making the test conclusion of the simulation test device for the uniformly distributed load deformation degree of the plate more intuitive.

[0027] For further information, see Appendix Figure 2 As shown, a plate sensing piece 6 for detecting the deformation value of the plate 2 to be tested is provided at the bottom of the plate 2 to be tested; a supporting keel sensing piece 7 for detecting the deformation value of the supporting keel 1 is provided at the bottom of the supporting keel 1. By providing the plate sensing piece 6 at the bottom of the plate 2 to be tested, the change data of the plate 2 to be tested when the plate 2 to be tested is subjected to the uniformly distributed load of the water tank is obtained, which is convenient for drawing test conclusions; by providing the supporting keel sensing piece 7 at the bottom of the supporting keel 1, the change data of the supporting keel 1 when the supporting keel 1 is subjected to the uniformly distributed load of the water tank is obtained, which is convenient for drawing test conclusions.

[0028] For the convenience of explanation, the following further explains the specific assembly and testing process of the simulation test device for the uniformly distributed load deformation degree of the plate.

[0029] During assembly, first observe the size of the plate 2 to be tested, select the number of supporting keels 1 and load water tanks 3 to be used according to the size of the plate 2 to be tested and the test requirements, and record the basic data of the plate 2 to be tested and the supporting keels 1; secondly, use the spacing adjustment components 43 on both ends of the supporting keels 1 to slide and connect the supporting keels 1 to the slide grooves 42 of the bracket 4, and adjust the relative distance between the supporting keels 1 according to the size of the plate 2 to be tested; after determining the relative distance, lock the spacing adjustment components 43 to complete the installation of the supporting keels 1 on the bracket 4.

[0030] Place the plate 2 to be tested on the fixed support keel 1. Next, press the load water tank 3 onto the top surface of the plate 2 to be tested. In addition, pass the support member 5 used through the slide groove 42 on the outer side surface of the bracket 4 to adjust the relative position of the support member 5 so that the support member 5 and the support keel 1 are arranged in line, and the supporting surface 51 of the support member 5 is inserted into the side wall of the load water tank 3. Next, a limit bolt 54 is provided on the fixing hole 53, passing through the fixing surface 52 and extending to the slide groove 42 on the outer side surface of the bracket 4, connecting and locking the support member 5 and the bracket 4, thereby completing the assembly of the simulation test device for the uniform load deformation degree of the plate.

[0031] During the test, first, according to the plate sensing piece 6 provided at the bottom of the plate 2 to be tested and the supporting keel sensing piece 7 provided at the bottom of the supporting keel 1, the data of the water level of the load water tank 3 being zero is recorded for the plate 2 to be tested and the supporting keel 1; secondly, according to the load required for the test, by observing the marked scale 31 on the load water tank 3, the water level of the load water tank 3 is controlled, and a uniform load is applied to the plate 2 to be tested and the supporting keel 1, and the corresponding plate sensing piece 6 and supporting keel sensing piece 7 change data are recorded, thereby completing the test of the simulation test device for the degree of deformation of the plate under uniform load.
