Description

Technical Field

[0001] This utility model relates to the field of column joint strength testing technology, specifically a side column joint strength testing device. Background Technology

[0002] The side column joint strength testing device is a specialized instrument used to accurately measure and evaluate the bonding strength between lateral columns and their connecting joints (such as beam connections and base connections) in structures (such as shelves, cabinets, and display racks). By simulating lateral forces or bending moments that may be encountered in actual use, a controllable load is applied to the target joint, and the applied load and joint deformation / displacement data are collected and analyzed in real time. This allows for the precise determination of the joint's yield strength, ultimate strength, stiffness, and failure mode, providing crucial verification evidence for structural safety and reliability.

[0003] Traditional node testing equipment requires applying high-intensity thrust to compress the test piece during node strength testing. This process demands extremely stable equipment bases to provide support. However, when the thrust exceeds 10 tons, the base still experiences significant displacement, ultimately leading to distorted test data. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: A side column joint strength testing device includes a steel frame mechanism and a testing mechanism. The steel frame mechanism includes two columns and a crossbeam connected between the two columns. The testing mechanism includes a detachable adapter connected to a column near the left end of the crossbeam, a hydraulic cylinder rotatably connected to the adapter, a hydraulic cylinder mounting component sleeved on the bottom of the hydraulic cylinder, a sensor mounting component located at the bottom of the hydraulic cylinder mounting component, a sensor connected between the hydraulic cylinder mounting component and the sensor mounting component, a bearing seat connected to the bottom of the sensor mounting component, and a base movably sleeved on the bottom of the bearing seat. A reinforcement mechanism is provided on one side of the base.

[0006] By adopting the above technical solution, during the period when the base is under force, the trapezoidal baffle prevents the base from tilting and shifting to the right. Then, multiple pressure rods press the side plate against the left side of the base by abutting the rod sleeve. This further reduces the probability of the base moving and ensures the reliability of the sensor data.

[0007] In a preferred embodiment, the present invention can be further configured as follows: the reinforcing mechanism includes a trapezoidal baffle that fits against one side of the base, two side plates that are inserted into the trapezoidal baffle, a plurality of rod sleeves that are respectively inserted into the trapezoidal baffle and the side plates, a pressure rod that is inserted into the top of the rod sleeve, and a clamping member connected between the plurality of pressure rods, wherein the clamping member is detachably connected to a column near the right end of the crossbeam.

[0008] In a preferred embodiment, the present invention can be further configured such that: multiple threaded holes are provided on the inner side of both columns, and the multiple threaded holes on the inner side of the columns are equally spaced and arranged in two columns.

[0009] In a preferred embodiment, the present invention can be further configured such that two side plates are respectively attached to the front and rear sides of the base, and both the trapezoidal baffle and the side plates are made of alloy material.

[0010] In a preferred embodiment, the present invention can be further configured such that the pressure bar is bent and the pressure bar is made of an elastic metal material.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, during the period when the base is under force, the trapezoidal baffle prevents the base from tilting and shifting to the right. Then, multiple pressure rods press the side plate against the left side of the base by abutting the rod sleeve, thereby further reducing the probability of the base moving and ensuring the reliability of the sensor data.

[0012] 2. In this utility model, the hydraulic cylinder provides a thrust of more than one ton, which then acts on the column at the left end of the crossbeam through the adapter. At the same time, the reaction force is transmitted to the sensor supported by the sensor mounting component, bearing seat, and base through the hydraulic cylinder mounting component. The sensor reflects the stress on the column in real time, thereby obtaining the node strength information. The testing method is simple and convenient to use. Attached Figure Description

[0015] 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 specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0016] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0017] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a side column node strength testing device.

[0018] Example 1: Combination Figure 1-5 As shown, the present invention provides a side column node strength testing device, which includes a steel frame mechanism 100, wherein the steel frame mechanism 100 includes two columns 110 and a crossbeam 120 connecting the two columns 110. The detection mechanism 200 includes a connector 210 detachably connected to a column 110 near the left end of the crossbeam 120, a hydraulic cylinder 220 rotatably connected to the connector 210, a hydraulic cylinder mounting component 230 sleeved on the bottom end of the hydraulic cylinder 220, a sensor mounting component 250 located at the bottom of the hydraulic cylinder mounting component 230, a sensor 240 connected between the hydraulic cylinder mounting component 230 and the sensor mounting component 250, a bearing seat 260 connected to the bottom of the sensor mounting component 250, and a base 270 movably sleeved on the bottom of the bearing seat 260. A reinforcement mechanism 300 is provided on one side of the base 270.

[0019] Specifically, the reinforcing mechanism 300 includes a trapezoidal baffle 310 attached to one side of the base 270, two side plates 320 inserted into the trapezoidal baffle 310, multiple rod sleeves 330 respectively between the trapezoidal baffle 310 and the side plates 320, a pressure rod 340 inserted into the top of the rod sleeve 330, and a clamping member 350 connected between the multiple pressure rods 340. The clamping member 350 is detachably connected to the column 110 near the right end of the crossbeam 120. Through the reinforcing mechanism 300, the top of the base 270 can be pressed, and the right side of the base 270 can also be pressed, so that the base 270 will not tip over or move to the right when pushed by the hydraulic cylinder 220.

[0020] Furthermore, multiple threaded holes are provided on the inner side of both columns 110. The multiple threaded holes on the inner side of the columns 110 are equally spaced and arranged in two rows. The threaded holes allow for flexible adjustment of the positions of the adapter 210 and the clamping member 350, providing conditions for flexible testing of the nodes of the columns 110.

[0021] Example 2: Combination Figure 1 , 4 and Figure 5 As shown, based on Embodiment 1, two side plates 320 are respectively attached to the front and rear sides of the base 270. The trapezoidal baffle 310 and the side plates 320 are both made of alloy material. The trapezoidal baffle 310 and the side plates 320 made of alloy material have high hardness and low deformation rate, which can firmly press the base 270.

[0022] Example 3: Combination Figure 1 and Figure 4 As shown, in the above embodiment, the pressure rod 340 is bent and made of elastic metal material. The use of elastic metal material gives the pressure rod 340 a certain degree of toughness, ensuring that the pressure rod 340 can firmly press the base 270.

[0023] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the hydraulic cylinder 220 provides a thrust of more than 10 tons, which then acts on the column 110 at the left end of the crossbeam 120 through the adapter 210. At the same time, the reaction force is transmitted to the sensor 240 supported by the sensor mounting part 250, bearing seat 260, and base 270 through the hydraulic cylinder mounting part 230. The sensor 240 reflects the stress on the column 110 in real time, thereby obtaining the node strength information. During this process, the trapezoidal baffle 310 prevents the base 270 from tilting and shifting to the right. Then, multiple pressure rods 340 press the side plate 320 against the left side of the base 270 by pressing against the rod sleeve 330, thereby further reducing the probability of the base 270 moving and ensuring the reliability of the sensor 240 data.

[0024] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
