Description

Technical Field

[0001] This invention relates to the field of static loading test technology, and in particular to a test device and test method for translational support of wall panel components. Background Technology

[0002] In building structural systems, self-supporting non-structural components such as partition walls play a crucial role in realizing building functions and dividing space. The "Code for Seismic Design of Buildings" clearly stipulates that non-structural components should have the ability to withstand earthquakes without collapsing or falling. With the development of new partition wall systems such as hollow steel mesh walls, lightweight metal-framed partition walls, and autoclaved aerated concrete (ALC) panels, it is necessary to verify and study the load-bearing capacity of wall panels under seismic loading through mechanical performance tests.

[0003] In traditional mechanical bending performance testing of wall panel components, static loading typically relies on hydraulic actuators to provide external force. This often necessitates designing the loading frame for the test based on the component's dimensions, or the component's size is limited by the specific loading frame used in the test. However, for non-structural wall panel components such as partition walls, the load-bearing capacity requirements are lower, and hydraulic actuation loading is not necessary. Therefore, using traditional static testing methods often leads to increased testing costs and limitations on component size.

[0004] Therefore, how to provide a more economical and efficient test device and test method for translational support of wall panel components that meets the requirements of low load-bearing capacity is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a test device for the translational support of wall panel components, comprising a support frame system and connecting rods connecting the support frame system. The support frame system includes multiple lifting support frames and at least two movable support frames inserted between the lifting support frames. Each lifting support frame and movable support frame includes a frame body, a hydraulic jack, a lifting and moving rod, a support, and a supporting tube. The frame body is assembled from two uprights, a crossbar, and diagonal braces. The lifting and moving rod is movably inserted inside the uprights. The hydraulic jack is installed at the bottom of the uprights, and the piston of the hydraulic jack extends into the uprights and contacts the bottom of the lifting and moving rod. The support is fixedly installed at the top of the lifting and moving rod, and the supporting tube is mounted on the supports on both sides. The side of the lifting support frame is provided with a slot-type connector, and the connecting rod is connected to the lifting support frames on both sides through the slot-type connector; The movable support frame has a movable base below the hydraulic jack, and a movable auxiliary pulley is provided on the side of the movable support frame.

[0008] Preferably, the mobile base includes a frame, a rotating ratchet, and a mobile track. The rotating ratchet is mounted on both sides of the frame, and the mobile track is sleeved on the outside of the rotating ratchet.

[0009] Preferably, the rotating ratchet is provided with a self-locking shaft.

[0010] Preferably, the movable auxiliary pulleys are arranged in two sets, one above the other.

[0011] Preferably, the support tube in the lifting support frame is welded to the support, and the support tube in the movable support frame is rotatably connected to the support.

[0012] Preferably, laser radar is mounted on the crossbars of the two lifting support frames located at both ends, and a laser target is mounted on the crossbar of the movable support frame.

[0013] The present invention also provides a method for testing the translational support of wall panel components, which uses the wall panel component translational support testing device as described above, and includes the following steps: Step 1: Control the hydraulic jacks of the lifting support frame and the moving support frame to push them out, so that all the supporting round pipes are at the same elevation. Step 2: The component to be tested is placed on top of the lifting support frame and the movable support frame by hoisting, and the component to be tested is supported by the support tube; Step 3: When loading the target working condition, control the hydraulic jack of the lifting support frame to descend and detach from the component to be tested, move the position of the moving support frame to the target position and fix it, and place it statically according to the test requirements and record the test data; Step 4: After the target working condition test of this group is completed, control the mobile base to move to the next target position and fix it until all target working conditions are tested.

[0014] Preferably, lidar is mounted on the crossbars of the two lifting support frames located at both ends, and a laser target is mounted on the crossbar of the movable support frame. The position of the movable support frame is adjusted based on the detected distance between the lidar and the laser target.

[0015] Preferably, the hydraulic jacks located on both sides of the same lifting support frame or movable support frame are simultaneously pushed out or lowered.

Detailed Implementation

[0019] To illustrate the technical solutions of the invention in more detail, specific embodiments are listed below to demonstrate the technical effects; it should be emphasized that these embodiments are used to illustrate the invention and not to limit the scope of the invention.

[0020] The wall panel component translation support test device provided by this invention, such as Figures 2 to 6 As shown, it includes a support frame system and a connecting rod 300 connecting the support frame system, wherein: The support system includes multiple lifting support frames 100 and at least two movable support frames 200 inserted between the lifting support frames 100. Each lifting support frame 100 and movable support frame 200 includes a frame body 110, a hydraulic jack 120, a lifting and moving rod 130, a support 140, and a supporting circular tube 150. The frame body 110 is assembled from two uprights 111, a horizontal bar 112, and a diagonal brace 113. The uprights 111 can be made of circular steel pipes. The lifting and moving rod 130 is movably inserted inside the uprights 111. The hydraulic jack 120 is installed at the bottom of the uprights 111. The piston 121 of the hydraulic jack 120 extends into the upright 111 and contacts the bottom of the lifting moving rod 130. The piston 121 is hydraulically controlled to lift and lower the lifting moving rod 130, which is used to assist in the installation of the component so that the component is located in the loading plane of the movable support frame 200. The crossbar 112 and the diagonal brace 113 are used to provide stable support for the frame 110. The top of the lifting moving rod 130 extends out of the upright 111 and is fixedly installed on the support 140. The support tube 150 is mounted on the support 140 on both sides and provides support for the component to be tested.

[0021] The lifting support frame 100 is provided with a slotted connector 160 on its side, and the connecting rod 300 is connected to the lifting support frames 100 on both sides through the slotted connector 160. The lifting support frame 100 is mainly used to assist in the installation of the component to be tested and to provide support for the component to be tested in a non-loaded state.

[0022] The movable support frame 200 has a movable base 210 below the hydraulic jack 120. The movable support frame 200 has auxiliary movable pulleys 220 on its side. The connecting rods 300 connecting the lifting support frames 100 located on both sides of the movable support frame 200 have grooves 310 that match the auxiliary movable pulleys 220, allowing the auxiliary movable pulleys 220 to roll along the length of the connecting rods 300, thus assisting the movable support frame 200 in completing the translational loading. The connecting rods 300 between two directly adjacent lifting support frames 100 can be circular connecting rods. The main function of the movable support frame 200 is translational test loading.

[0023] The working principle of this invention is as follows: Figure 1 As shown, a uniformly distributed load is applied to wall panel components by the self-weight of the wall panel. Q The support span was adjusted by translation. l This causes the mid-span bending moment of the component to increase during the translation process. M With support span l Change, among which L The total span of the component.

[0024] This invention employs a modular support frame system, which can be designed with different verification conditions according to test requirements. By adjusting the number and spacing of the lifting support frames 100 and combining them with connecting rods 300 of different lengths, it can be applied to components of different sizes. By adjusting the position of the movable support frame 200, the loading requirements of different working conditions can be met.

[0025] In some embodiments, please refer to Figure 2 Specifically, the slot-type connector 300 has two slot holes, and the two ends of the connecting rod 300 are provided with fasteners. The size of the fasteners matches the slot holes. In this way, the fasteners on the connecting rod 300 are inserted into the slot holes of the slot-type connector 300, so that the two can be detached and quickly connected.

[0026] In some embodiments, please refer to the following: Figure 5 and Figure 6 The mobile base 210 includes a frame 211, a rotating ratchet 212, and a moving track 213. A motor is installed inside the frame 211 to provide power for movement. The rotating ratchet 212 is mounted on both sides of the frame 211, and the moving track 213 is sleeved on the outside of the rotating ratchet 212. In some embodiments, the rotating ratchet 212 is equipped with a self-locking shaft 214. Since increased deformation of the support frame may subject it to lateral thrust, the self-locking shaft 214 on the rotating ratchet 212 enables position locking. After the mobile support frame 200 moves to the target position, the mobile base 210 is locked to prevent lateral movement. In this embodiment, the mobile base 210 has both bidirectional movement and self-locking functions, and is controlled by an external control system via a communication and control module.

[0027] In some embodiments, please refer to Figure 5 and Figure 6 The movable auxiliary pulleys 220 are arranged in two sets, one above the other. The movable auxiliary pulleys 220, together with the grooves 310 on the connecting rod 300, are used to fix the translational trajectory of the movable support frame 200.

[0028] In some embodiments, the support tube 150 in the lifting support frame 100 is welded to the support 140, and its function is to contact the component to be tested to simulate the hinged support state of the component; the support tube 150 in the movable support frame 200 is rotatably connected to the support 140, which facilitates the translation operation of the movable support frame 200 while simulating the hinged support state of the component.

[0029] In some embodiments, please refer to the following: Figure 2 The two lifting support frames 100 located at both ends are equipped with laser radar 170 on the crossbar 112, and the mobile support frame 200 is equipped with laser target 230 on the crossbar 112, which is used to perform real-time ranging during the test. The results are transmitted to the control system through the communication module in the laser radar 170 to assist the mobile base 210 in making bidirectional movement decisions.

[0030] The present invention also provides a method for testing the translational support of wall panel components, which uses the wall panel component translational support testing device as described above, and includes the following steps: First, conduct the experimental design: The self-weight load of a wall can be determined in two ways: one is to calculate the self-weight per unit area based on material parameters, and the other is to directly weigh the actual test wall. The self-weight load distributed along the length direction can be determined based on the width of the component to be tested. Q Based on this, the target inspection bending moment under each working condition needs to be set. M i .

[0031] The determination of the target test bending moment should be based on the equivalent lateral force method specified in the "Code for Seismic Design of Buildings" (GB 50011-2010). This method calculates the standard value of the horizontal seismic force acting at the center of gravity of a non-structural member using the following formula: F i =γηζ 1 ζ 2 α max G In the formula: γ This is the functional coefficient for non-structural components, which is adjusted according to the different functions undertaken by the wall. η For non-structural component category coefficients; ζ 1 The state factor is 2.0 for precast components and cantilever components, and 1.0 for the rest. ζ 2This is the location coefficient, linearly interpolated from 1.0 at the bottom of the building to 2.0 at the top; α max This represents the maximum value of the earthquake influence coefficient. G This refers to the gravity of non-structural components (including the combined value of permanent and variable loads).

[0032] The horizontal seismic action is further converted into the target verification bending moment using the following formula: Mi = FiL / 4 Determine the target inspection bending moment for each working condition. M i Then, based on the bending moment M i With support span l i Relationship (see) Figure 1 ), calculate the minimum support span for each working condition. l 1 and maximum support span l n .

[0033] Then proceed with the pre-experiment preparations: A support frame system was constructed to support the components to be tested, according to the requirements of the experimental design. This was done for components of varying lengths. L The number of lifting support frames 100 and the length of connecting rods 300 are adjustable.

[0034] First, mark the center line of the support frame at the test site. Then, mark the installation positions of the modular support frame according to the center line, and mark the minimum support span for each frame. l 1 and maximum support span l n Lower the support frame to position 200. Minimum support span. l Within a range of 1, 4-6 lifting support frames of 100 are symmetrically placed, at the maximum support span. l n To the span of the support frame system L system Two to four symmetrically placed lifting support frames 100 are used to ensure support for the component under test in the unloaded state. A movable support frame 200 is placed at the minimum support span. l 1. The corresponding position facilitates loading of the first set of working conditions. Adjust the moving auxiliary pulley 220 to engage with the sliding groove 310 in the connecting rod 300. Adjust the moving base 210 to the locked state through the control system, and turn on the lidar 170 to check whether its ranging result is ( L system -l 1) / 2, verify the position of the mobile support frame 200 and the installation status of the lidar 170.

[0035] Then proceed with the following steps: Step 1: Control the hydraulic jacks 120 of the lifting support frame 100 and the moving support frame 200 to push out, so that all the supporting round tubes 150 are at the same elevation.

[0036] Step 2: The component to be tested (not shown) is placed on top of the lifting support frame 100 and the movable support frame 200 by hoisting, and the component to be tested is supported by the support tube 150. At this time, it is necessary to ensure that the component to be tested is placed symmetrically along the central axis of the support frame (including the lifting support frame 100 and the movable support frame 200) to prevent torque from being generated during loading and thus affecting the test results.

[0037] Step 3: When loading the target working condition, control the hydraulic jacks 120 of the lifting support frame 100 to unload in the order from the center to both ends, and detach them from the component to be tested. At this time, the self-weight load of the component to be tested is completely borne by the moving support frame 200. Then, according to the test requirements, let it stand still and record the test data.

[0038] Step 4: After the target conditions for this group are detected, control the mobile base 210 to move to the next target position and fix it, until all target conditions are detected. Specifically, control the mobile base 210 to move to both sides, and determine whether to stop based on the distance measurement data fed back from the lidar 170. When the distance measurement feedback data matches the design distance for the corresponding condition ( L system -l i When the error is ≤2mm, the translation operation of the moving support frame 200 can be stopped, the self-locking function can be activated (i.e., the self-locking rotating shaft 214 can be locked) to fix the position of the moving support frame 200, and then it can be left to stand still and the data can be recorded.

[0039] In some embodiments, hydraulic jacks 120 located on both sides of the same lifting support frame 100 or movable support frame 200 are simultaneously pushed out or lowered to achieve smooth changes in working conditions.
