Description

Technical Field

[0001] This utility model relates to the field of civil engineering testing technology, specifically to a multifunctional hinged support and test beam loading device. Background Technology

[0002] Structural testing in civil engineering is the primary means of testing the various properties of structural components, and the test loading device is an important guarantee for ensuring the safe, standardized, and reasonable conduct of the test. In engineering, the device that connects a structure or component to a support is called a support. Among them, the hinged support is one of the most common types of support and is also an essential test device used in the loading test of reinforced concrete beams.

[0003] Currently, most hinged supports used for loading test beams are single-function, split devices. Each test beam needs to be installed before loading. This repeated installation is not only time-consuming, but also makes it impossible to adjust the position of the support point after installation. Once the test beam is moved, the device will automatically separate, which greatly increases the test preparation time and the risk of being injured by iron parts during the preparation process. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a multifunctional hinge support and test beam loading device to solve the technical problem that the split hinge support in the prior art needs to be assembled before each test.

The first support member is connected to the pillar and can move along the length of the pillar. The upper plate is placed on the first support member; A roller is placed on the lower plate, and the upper surface of the roller is an arc surface that abuts against the lower surface of the upper plate.

[0006] In some embodiments, the side of the support column is formed with external threads, and the lower plate and the first support member are formed with threaded holes corresponding to the external threads.

[0007] In some embodiments, the supports are arranged in a matrix, and four threaded holes corresponding to the supports are formed on the lower plate.

[0008] In some embodiments, a U-shaped groove corresponding to the support column is formed on the upper plate, and the width of the U-shaped groove is greater than the outer diameter of the support column.

[0009] In some embodiments, a sliding frame and a roller are also included, the sliding frame being located below the lower plate and detachably connected to the support column, and the roller being located within the sliding frame and capable of rolling freely.

[0010] In some embodiments, a second support member is further included, which is correspondingly connected to the support column and is movable along the length direction of the support column, wherein the upper surface of the second support member abuts against the lower surface of the lower plate.

[0011] In some embodiments, the side of the support column is formed with external threads, and the sliding frame and the second support member are formed with threaded holes corresponding to the external threads.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To address the technical problem that existing split hinge supports require assembly before each test, this invention provides a multifunctional hinge support that can achieve integrated hinge support design.

[0019] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the multifunctional hinge support provided in this embodiment of the utility model. The multifunctional hinge support includes an upper plate 1, a lower plate 2, a support column 3, a first support member 4, and a roller 5.

[0020] Multiple support columns 3 are detachably connected to the lower plate 2. Multiple first support members 4 are connected one-to-one with the support columns 3 and can move along the length of the support columns 3 or be fixed to the support columns 3. The upper plate 1 is placed on the first support members 4 and is used to place the test beam. The roller 5 is placed on the lower plate 2, and the upper surface of the roller 5 is an arc surface that abuts against the lower surface of the upper plate 1.

[0021] Please see Figures 2 to 4 , Figure 2 yes Figure 1 Front view of the upper middle plate; Figure 3 yes Figure 1 Front view of the lower middle plate; Figure 4 yes Figure 1 The front view of the sliding box.

[0022] In some embodiments, a U-shaped groove 11 corresponding to the support column 3 is formed on the upper plate 1. The support column 3 passes through the U-shaped groove 11, and the width of the U-shaped groove 11 is slightly larger than the outer diameter of the support column 3, so that the support column 3 and the upper plate 1 can move freely. The U-shaped groove 11 serves to position and limit movement.

[0023] In some embodiments, the side of the support column 3 is formed with external threads, and the lower plate 2 and the first support member 4 are formed with threaded holes corresponding to the external threads. The support column 3 is preferably arranged in a matrix, and the lower plate 2 is formed with four first threaded holes 21 corresponding to the support column 3.

[0024] In some embodiments, the support column 3 may be a screw, and the first support member 4 may be a matching nut.

[0025] In some embodiments, the lower surface of the roller 5 is an arc surface, that is, the cross-section of the roller 5 is circular. In other embodiments, the lower surface of the roller 5 is a plane, that is, the cross-section of the roller 5 is arched, the upper half is a semicircle, the lower half is a rectangle, and the length of the side connecting the rectangle and the semicircle is equal to the diameter of the semicircle.

[0026] In some embodiments, the multi-functional hinge support also includes a sliding frame 6 and a roller 7. The sliding frame 6 is located below the lower plate 2 and is detachably connected to the support column 3. The roller 7 is located inside the sliding frame 6 and can roll freely.

[0027] In some embodiments, the multifunctional hinge support further includes a second support member 8, which is correspondingly connected to the column 3 and can move along the length direction of the column 3. The upper surface of the second support member 8 abuts against the lower surface of the lower plate 2, thereby providing auxiliary support for the lower plate 2.

[0028] When the side of the support column 3 has external threads, the sliding frame 6 also has corresponding rectangularly arranged second threaded holes 61. The second support member 8 also has threaded holes corresponding to the external threads of the support column 3. The second support member 8 is similar to the first support member 4 and can also use a matching nut.

[0029] Please see Figure 5 and Figure 6 , Figure 5 This is a side view of the test beam loading device provided in this embodiment of the utility model; Figure 6 This is a top view of the test beam loading device provided in this embodiment of the present invention. The test beam loading device includes at least two parallel multi-functional hinge supports 100, and the test beam 200 is placed on the upper plate.

[0030] In some embodiments, such as Figure 5 As shown, one of the multifunctional hinge supports 100 uses a first roller 5A with a circular cross-section, and the other multifunctional hinge support 100 uses a second roller 5B with an arched cross-section. In other embodiments, both multifunctional hinge supports 100 may use either the first roller 5A or the second roller 5B.

[0031] The specific method for conducting the test using a fixed hinge support is as follows: First, pass the four uprights 3 through the U-shaped grooves 11 at the four corners of the upper plate 1. Then, screw the four first support members 4 into the four uprights 3. Keeping the four first support members 4 on the same horizontal plane is beneficial for the horizontal placement of the upper plate 1. The screwing depth should be greater than the diameter of the roller 5 and the thickness of the lower plate 2 to ensure sufficient space for the roller 5. Then, screw all four uprights 3 into the lower plate 2, with the screwing depth of the uprights 3 equal to the thickness of the lower plate 2. After installation, place the hinge support in the corresponding position on the test bench, then place the test beam 200 on the hinge support and adjust the position of the test beam 200 according to the test requirements. After adjustment, place the roller 5 into the device, i.e., in the middle of the upper surface of the lower plate 2. Finally, screw the four first support members 4 downwards until the roller 5 contacts the lower surface of the upper plate 1, forming a fixed hinge support. After assembly, apply the load to the test beam 200 according to the test requirements and begin the test loading.

[0032] The specific method for conducting the test using a sliding hinge support is as follows: Four uprights 3 are passed through the U-shaped grooves 11 at the four corners of the upper plate 1, and four first support members 4 are screwed into the four uprights 3. Keeping the four first support members 4 on a uniform horizontal plane facilitates the horizontal placement of the upper plate 1. The screwing depth should be greater than the diameter of the roller 5 and the thickness of the lower plate 2 to allow sufficient space for the roller 5. Then, all four uprights 3 are screwed into the lower plate 2, extending a certain length through it, with the protruding length approximately equal to the total thickness of the sliding frame 6 and the second support member 8. Next, the four second support members 8 are screwed into the uprights 3 and make contact with the lower surface of the lower plate 2. The sliding frame 6 is then placed at the corresponding position on the test bench, and several rollers 7 are placed inside the sliding frame 6. Finally, the four uprights 3 are screwed into the second threaded holes 61 at the four corners of the sliding frame 6. The screwing depth of the uprights 3 is equal to the thickness of the sliding frame 6. At this point, the upper part of the roller 7 contacts the lower surface of the lower plate 2, and the lower part of the roller 7 contacts the test bench, allowing it to slide horizontally on the test bench. After installation, place the hinge support at the corresponding position on the test bench, then place the test beam 200 on the hinge support and adjust its position according to the test requirements. After adjustment, insert the roller 5 into the device, specifically into the middle of the upper surface of the lower plate 2. Finally, screw the four first support members 4 downwards until the roller 5 contacts the lower surface of the upper plate 1, thus forming a sliding hinge support. After assembly, apply the load to the test beam 200 according to the test requirements and begin the test loading.

[0033] Easy to understand Figure 5 The test beam loading device shown uses two fixed hinge supports. Depending on the test requirements, two sliding hinge supports, or one fixed hinge support and one sliding hinge support, can also be used.
