Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, specifically relating to an anti-tipping support detection base and support detection assembly for prestressed double-T slabs. Background Technology

[0002] The structural design of prestressed double-T slabs is relatively complex, involving multiple parameters and details such as span, load, and the arrangement of prestressing tendons, all of which increase the difficulty of positioning. High-precision positioning is required during loading tests to ensure the stability and safety of the structure and prevent tipping. However, even minor deviations during testing can lead to decreased structural performance or safety hazards. The environment, space limitations, and foundation conditions at the testing site can all affect the positioning of the prestressed double-T slabs. For example, confined spaces can increase the difficulty of positioning. If the double-T slab is not placed correctly, it may tip over due to failure to use the appropriate stable positioning method during loading. Currently, due to the structural and shape characteristics of prestressed double-T slabs, there are no specialized tools to ensure their stability before and during testing, and there is a lack of appropriate stabilizing supports or fixed measures according to relevant standards. Furthermore, before or during the use or testing of double-T slabs, natural disasters such as strong winds and earthquakes may subject them to additional external forces. These environmental factors may also affect the stability of the double-T slabs, thereby increasing the risk of tipping over. Currently, there are no anti-tipping support components suitable for adjusting prestressed double-T slabs during the testing process. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. The structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0030] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0031] Specific implementation method one: Combining Figures 1 to 9 This embodiment describes a tilt-resistant support testing base for prestressed double-T slabs. This base is specifically designed to provide support, protection, and testing functions during loading tests of prestressed double-T slabs. Its location is determined based on specific usage requirements. It serves both as a stable support before testing and as a testing device for prestressed double-T slabs 15 under varying loading requirements, enabling testing at specific locations under stable support conditions. Specifically, it includes a base plate 1, a main support frame 2, a testing unit 3, and a top support seat 4. The base plate 1 is horizontally positioned, and the main support frame... 2. Vertically installed on the base plate 1, which is made of steel plate and serves as bottom support. The main support frame 2 serves as vertical support and is used to directly support the detection unit 3 and the top support seat 4. The detection unit 3 is installed on the main support frame 2 during the detection process. The detection unit 3 is installed on the main support frame 2 along the width direction of the main support frame 2. The top of the main support frame 2 is detachably connected to the top support seat 4. The top outer wall of the top support seat 4 is close to the bottom of the panel 15-1 of the prestressed double T plate 15. The detection surface of the detection unit 3 is close to the side wall of the rib beam 15-2 of the prestressed double T plate 15.

[0032] The support testing object in this embodiment is a prestressed double-T plate 15. The prestressed double-T plate 15 includes a panel 15-1 and two ribs 15-2. Two ribs 15-2 are vertically arranged side by side below the panel 15-1. The prestressed double-T plate 15 is an existing structural plate, and its structural composition is consistent with that of existing prestressed double-T plates.

[0033] Combination Figure 1 and Figure 6 As shown, in this embodiment, the anti-tipping support detection base is formed in different specifications according to the different specifications of the prestressed double T plate 15. The width and height of the main support frame 2 are specifically configured according to the specific specifications of the prestressed double T plate 15. The insertion position of the detection unit 3 is determined according to the specific design requirements. It is ensured that the detection surface of the detection unit 3 is close to the corresponding position of the side wall of the rib beam 15-2 of the prestressed double T plate 15.

[0034] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. In this implementation method, the detection unit 3 has multiple forms. One type is a structure that plays a tensile role. The corresponding structural form of the detection unit 3 includes a backing plate 3-1, a through-steel bar 3-2, a force sensor 3-3, a force transmission frame 3-4, and a rolling disk 3-5. The through-steel bar 3-2 passes through the main support frame 2 along the width direction. One end of the through-steel bar 3-2 is fitted with a force sensor 3-3. The force transmission frame 3-4 is a square frame. The rolling disk 3-5 is set inside the force transmission frame 3-4. The backing plate 3-1 is set at one end of the force transmission frame 3-4 facing the side wall of the rib beam 15-2 of the prestressed double T plate 15. The other end of the through-steel bar 3-2 passes through the force transmission frame 3-4 and the rolling disk 3-5 in sequence and is connected to the backing plate 3-1.

[0035] In this embodiment, the detection unit 3 is an external local load loading detection component, capable of applying constant stress according to different test conditions to accurately simulate out-of-plane load effects. The configuration of the rolling disk 3-5 effectively eliminates the test errors caused by traditional sliding friction. At the same time, the axial load change is monitored in real time by the high-precision force sensor 3-3 to ensure that the axial load remains constant throughout the entire test.

[0036] In this embodiment, the combination of the detection unit 3 and the top support 4 is particularly suitable for carrying out relevant detection processes under stable support conditions. Among them, the force sensor 3-3 is an existing sleeve-type sensor, specifically a high-sensitivity force sensor, used to acquire load signals and monitor prestress changes in real time.

[0037] In this embodiment, the force-transmitting frame 3-4 is essentially a force-transmitting bracket. The reinforcing bars 3-2 are prestressed reinforcing bars.

[0038] In this embodiment, the detection unit 3 can also be a structure subjected to shear forces. The corresponding structural form of the detection unit 3 includes a contact plate 3-1, through-steel bars 3-2, a force sensor 3-3, a force transmission frame 3-4, and a rolling disc 3-5. The only difference from a structure subjected to tension forces is the direction of the through-steel bars 3-2; the through-steel bars 3-2 are vertically inserted into the force transmission frame 3-4, the rolling disc 3-5 is positioned above the through-steel bars 3-2, and the force sensor 3-3 is mounted on the lower end of the through-steel bars 3-2. In practical use, the specific number and arrangement of the detection units 3 subjected to shear forces and tension forces can be configured according to the detection requirements.

[0039] Furthermore, when the reinforcing bar 3-2 is a steel sleeve, the force sensor 3-3 is a force sensing component, which includes a wire, a probe and a controller. The probe is installed on the abutment plate 3-1 and is flush with the surface of the abutment plate 3-1. One end of the wire passes through the steel sleeve and is connected to the controller, and the other end of the wire is connected to the probe. At this time, the detection unit 3 is a detection structure for realizing the adhesive detection process.

[0040] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. In this implementation method, the inner wall of the abutment plate 3-1 is fixedly connected to the force transmission frame 3-4, and the outer wall surface of the abutment plate 3-1 is the detection surface. Multiple embedded rods 3-6 are arranged side by side on the detection surface. Each embedded rod 3-6 is a probe. One end of each embedded rod 3-6 is fixedly connected to the outer wall surface of the abutment plate 3-1, and the other end of each embedded rod 3-6 is embedded in the prestressed double-T plate 15. When the detection unit 3 is a pre-embedded detection structure, it is embedded during the casting and manufacturing process of the prestressed double-T plate 15. The embedding depth of the embedded rod 3-6 in the prestressed double-T plate 15 is determined according to the requirements of specific sample tests or sampling tests.

[0041] Specific Implementation Method Four: This implementation method is a further limitation of Specific Implementation Method One, Two or Three. In this implementation method, the force transmission frame 3-4 includes a main board 3-4-1 and two side plates 3-4-2. The two side plates 3-4-2 are arranged side by side, and the main board 3-4-1 is arranged between the two side plates 3-4-2. The two sides of the main board 3-4-1 are fixedly connected to the inner walls of the two side plates 3-4-2 respectively. The main board 3-4-1 has a first through hole 5 along its thickness direction to cooperate with the through steel bar 3-2.

[0042] Specific Implementation Method 5: This implementation method is a further limitation of Specific Implementation Methods 1, 2, 3, or 4. In this implementation method, the rolling disk 3-5 includes a main carrier plate 3-7 and two sets of multiple rolling rollers 3-8. Two mounting holes 6 are machined side by side along the thickness direction on the main carrier plate 3-7. A second through hole 7 is machined along the thickness direction on the main carrier plate 3-7. The second through hole 7 is located between the two mounting holes 6. Each mounting hole 6 is provided with a set of multiple rolling rollers 3-8. The multiple rolling rollers 3-8 include a shaft body 3-8-1 and multiple bushings 3-8-2. The two ends of the shaft body 3-8-1 are respectively connected to the inner walls of the two ends of the mounting hole 6. The multiple bushings 3-8-2 are fitted on the shaft body 3-8-1. The inner wall of each bushing 3-8-2 is separated from the outer wall of the shaft body 3-8-1.

[0043] In this embodiment, the rolling disk 3-5 is a multi-position rotating device composed of a high-precision perforated steel plate and a low-friction bearing. The multi-position rotating device is fixed in the force transmission frame 3-4. The bushing 3-8-2 is specifically a bearing, which has undergone smoothing and lubrication treatment. The placement of multiple bushings 3-8-2 reduces frictional resistance during the detection process. For installation, the reinforcing bar 3-2 is precisely fixed by adjusting the nut. A force sensor 3-3 is fitted onto one end of the reinforcing bar 3-2 after it passes through the force transmission frame 3-4, and the force sensor 3-3 monitors changes in prestress in real time.

[0044] In this embodiment, the setting of the rolling disk 3-5 effectively solves the technical problem of coordinating the displacement of the through-steel bar 3-2 and the prestressed double T plate 15, ensuring that the load direction and the displacement of the prestressed double T plate 15 are kept synchronized in real time, and significantly improving the accuracy of the test data.

[0045] Furthermore, the first through hole 5 on the force transmission frame 3-4 is a reserved hole with optimized dimensions. It provides sufficient space for movement while ensuring structural strength, ensuring smooth movement of the inserted steel bar 3-2. Together with the main support frame 2, it achieves high-precision control during the loading process and stability during the detection process.

[0046] Furthermore, the first through hole 5 is a rectangular or oblong hole.

[0047] Specific Implementation Method Six: This implementation method is a further limitation of Specific Implementation Methods One, Two, Three, Four or Five. The top support base 4 includes a connecting rod 4-1, a sub-support frame 4-2 and an inclined support plate 4-3. The upper end of the connecting rod 4-1 is hinged to the bottom of the sub-support frame 4-2. The top of the main support frame 2 is machined with a threaded hole. The lower end of the connecting rod 4-1 is threadedly connected to the top of the main support frame 2 through the threaded hole. After connection, the connection position of the two is fixed by a nut. An inclined support plate 4-3 is provided on the top of the sub-support frame 4-2. The top surface of the inclined support plate 4-3 is closely attached to the bottom of the panel 15-1 of the prestressed double T plate 15.

[0048] Furthermore, the bottom of the sub-support frame 4-2 is machined with a connecting blind hole, and the upper end of the connecting rod 4-1 passes through the connecting blind hole and the two are hinged together, so as to ensure that the rotation of the connecting rod 4-1 does not affect the synchronous rotation of the sub-support frame 4-2, thereby ensuring that the inclined support plate 4-3 is in a stable position and abuts against the bottom of the panel 15-1 of the prestressed double T plate 15 at the corresponding position.

[0049] Furthermore, the inclined support plate 4-3 is an inclined plate body, and its position and the positional relationship of the inclined setting are to adapt to the shape of the bottom of the panel 15-1 of the prestressed double T plate 15, so as to achieve the effect of closely adhering to the bottom of the support panel 15-1.

[0050] Furthermore, a pad, which can be made of plastic or metal, is provided on the top surface of the inclined support plate 4-3 to increase the flexible contact effect during the contact process with the bottom of the panel 15-1.

[0051] Furthermore, the sub-support frame 4-2 is an inclined groove structure, with both ends connected and the two sides having a height difference, forming an inclined U-shaped support frame. This design facilitates the replacement of the inclined support plate 4-3.

[0052] The adjustment principle of the top support 4 in this embodiment is as follows:

[0053] After determining the vertical height of the parts requiring support on the prestressed double-T slab 15 according to specific requirements, the anti-tipping support test seat of the prestressed double-T slab is arranged below the corresponding position of the prestressed double-T slab 15. Adjust the connecting rod 4-1, and after inserting the connecting rod 4-1 through the threaded hole at the top of the main support frame 2, raise or lower it by screwing the connecting rod 4-1 to achieve the height adjustment of the inclined support plate 4-3. After ensuring that the inclined support plate 4-3 is in a stable position against the bottom of the panel 15-1 of the prestressed double-T slab 15 by adjusting the raising or lowering of the connecting rod 4-1, tighten the connecting rod 4-1 by fitting a nut on it.

[0054] Embodiment Seven in Detail: This embodiment is a further limitation of Embodiment One, Two, Three, Four, Five or Six in Detail. The main support frame 2 is a frame body with a U-shaped cross-section in the horizontal direction. Its structure with three sides enclosed and one side open is conducive to the collaborative installation and debugging of the detection monomer 3 and the top support seat 4. The main support frame 2 includes a top plate 2-1, a first vertical plate 2-2 and two second vertical plates 2-3. The two second vertical plates 2-3 are arranged vertically and side by side. The first vertical plate 2-2 is vertically arranged between the two second vertical plates 2-3. The two sides of each first vertical plate 2-2 are respectively fixedly connected to the side parts of the two second vertical plates 2-3. The top plate 2-1 is a square plate. The top plate 2-1 is arranged on the tops of the first vertical plate 2-2 and the two second vertical plates 2-3. The two ends of the top plate 2-1 are respectively fixedly connected to the two second vertical plates 2-3. One side of the top plate 2-1 close to the first vertical plate 2-2 is fixedly connected to the first vertical plate 2-2.

[0055] Embodiment Eight in Detail: This embodiment is a further limitation of Embodiment One, Two, Three, Four, Five, Six or Seven in Detail. An inclined support member 11 is inclinedly arranged on the bottom plate 1. The inclined support member 11 is inclinedly arranged between the bottom plate 1 and the main support frame 2. The inclined support member 11 is respectively fixedly connected to the bottom plate 1 and the main support frame 2. The inclined support member 11 plays a role in assisting in supporting the main support frame 2.

[0056] This anti-tipping support detection seat body for prestressed double-T slabs can be specifically used in the pseudo-static test of prestressed double-T slabs 15. The working principles of actuators or other necessary components not mentioned in the pseudo-static test are the same as those of the necessary components involved in the existing pseudo-static test.

[0057] The working principle of the anti-tipping support detection seat body 10 in this embodiment:

[0058] When used in the support process before the test, according to specific requirements, configure the layout position of the anti-tipping support detection seat body 10, move the bottom plate 1, and the movement of the bottom plate 1带动 the main support frame 2 to move to a predetermined position at the bottom of the panel 15-1 of the prestressed double-T slab 15. Then, through adjusting the lifting of the top support seat 4, the process of making it closely adhere to the predetermined position at the bottom of the panel 15-1 of the prestressed double-T slab 15 is achieved. At this time, the detection monomer 3 can be idle and ineffective, or lean against the side wall of the rib beam 15-2 of the prestressed double-T slab 15 to play an auxiliary support effect, and wait for subsequent detection.

[0059] When used in a specific testing process, the anti-tipping support testing seat 10 is configured with a specific testing position according to the specific requirements. The base plate 1 is moved, and the movement of the base plate 1 drives the main support frame 2 to move to the predetermined position at the bottom of the panel 15-1 of the prestressed double T plate 15. Then, by adjusting the lifting and lowering of the top support seat 4, it is made to be in close contact with the predetermined position at the bottom of the panel 15-1 of the prestressed double T plate 15, ensuring that the abutment plate 3-1 in the testing unit 3 is in contact with the predetermined testing position.

[0060] Specific Implementation Method Nine: Combining Figures 1 to 10 This embodiment describes the anti-tipping support testing assembly for the prestressed double-T slab, which includes a clamping block 8, two limiting plates 9, and at least two anti-tipping support testing seats 10. The two limiting plates 9 are arranged horizontally side by side, and the clamping block 8 is detachably connected between the two limiting plates 9. The limiting plates 9 are arranged one-to-one with the ribs 15-2 of the prestressed double-T slab 15. Each limiting plate 9 has a semi-groove 9-1 that matches the bottom end of its corresponding rib 15-2. One side of the bottom of each rib 15-2 is close to the side wall of its corresponding semi-groove 9-1. At least one anti-tipping support testing seat 10 is provided on the outer side wall of each rib 15-2.

[0061] Each anti-tipping support testing seat 10 includes a base plate 1, a main support frame 2, a testing unit 3, and a top support seat 4. The base plate 1 is horizontally set on a limiting plate 9 nearby. The main support frame 2 is vertically set on the base plate 1. The testing unit 3 passes through the main support frame 2 along the width direction. The top support seat 4 is detachably connected to the top of the main support frame 2. The top outer wall of the top support seat 4 is in close contact with the bottom of the panel 15-1 of the prestressed double T plate 15. The testing surface of the testing unit 3 is in close contact with the side wall of the rib beam 15-2 of the prestressed double T plate 15.

[0062] In this embodiment, the anti-tipping support testing base 10 can be used alone or in multiples. It can be arranged at the predetermined position of the prestressed double-T plate 15 according to the support needs and test requirements. When multiple anti-tipping support testing bases 10 are used, they are combined with the clamping block 8 and the two limiting plates 9 to form an anti-tipping support testing assembly.

[0063] In this embodiment, the anti-tipping support detection assembly can achieve multi-position fixing effect to prevent the side of the prestressed double T plate 15 from tipping over. The width of the clamping block 8 is determined according to the different specifications of the prestressed double T plate 15. After the two limiting plates 9 respectively limit the two ribs 15-2 of the prestressed double T plate 15, they can be stably clamped and limited by the clamping block 8, making the anti-tipping support detection assembly universal in use.

[0064] In this embodiment, a diagonal brace 11 is inclinedly provided on the base plate 1. The diagonal brace 11 is inclinedly positioned between the base plate 1 and the main support frame 2, and is fixedly connected to the base plate 1 and the main support frame 2 respectively. The diagonal brace 11 serves to assist in supporting the main support frame 2, and together with the limiting plate 9, forms a clamping and positioning effect on both sides of the rib beam 15-2.

[0065] Combination Figure 10 As shown in the figure, area A is the arrangement area of ​​the detection unit 3, and area B is the arrangement area of ​​the top support 4. The specific arrangement position is adjusted according to specific requirements.

[0066] Structures and connections not mentioned in this embodiment are the same as those in specific embodiments one, two, three, four, five, six, seven, eight, or nine.

[0067] The working principle of the anti-tipping support detection assembly in this embodiment is as follows:

[0068] When used only for the support process before testing, the number of anti-tipping support test seats 10 and the arrangement position of each anti-tipping support test seat 10 are configured according to specific requirements. The operating principle of each anti-tipping support test seat 10 is as follows: the base plate 1 is moved, and the movement of the base plate 1 drives the main support frame 2 to move to the predetermined position at the bottom of the panel 15-1 of the prestressed double T plate 15. Then, by adjusting the lifting and lowering of the top support seat 4, it is achieved that it is in close contact with the predetermined position at the bottom of the panel 15-1 of the prestressed double T plate 15, and then it can wait for subsequent testing.

[0069] When used in the testing process, the number of anti-tipping support testing seats 10 and the testing positions of each testing unit 3 are configured according to specific requirements. The operating principle of each anti-tipping support testing seat 10 is as follows: the base plate 1 is moved, and the movement of the base plate 1 drives the main support frame 2 to move to the predetermined position at the bottom of the panel 15-1 of the prestressed double T plate 15. Then, by adjusting the lifting and lowering of the top support seat 4, it is made to be in close contact with the predetermined position at the bottom of the panel 15-1 of the prestressed double T plate 15, thereby ensuring that the abutment plate 3-1 in the corresponding testing unit 3 in the anti-tipping support testing seat 10 is in contact with the predetermined testing position. After arranging other testing units 3 in the same manner, the relevant test data can be obtained.
