Description

Technical Field

[0001] This utility model belongs to the field of template testing technology, and more specifically, it relates to a device for testing the strength of template supports in building engineering. Background Technology

[0002] As a key supporting component in concrete pouring and forming, the formwork in building construction directly affects the construction quality and on-site operation safety due to its supporting strength and structural stability. Before the formwork is put into use, it is usually necessary to use a special testing device to test the compressive strength and load-bearing capacity of the formwork to ensure that the formwork meets the on-site support stress requirements.

[0003] For example, existing application number CN202222105387.X relates to the field of construction formwork testing technology and discloses a construction formwork strength support detector, including a top frame, a stepper motor, and a bottom frame. The stepper motor is fixedly connected inside the top frame, and a threaded rod is connected to the bottom of the stepper motor. A movable sleeve is movably connected to the outer wall of the threaded rod, and a connecting plate is fixedly connected to the left side of the movable sleeve. The bottom frame is fixedly connected to the bottom of the top frame, and a grounding seat is fixedly connected to the bottom of the bottom frame. The grounding seat is composed of an I-beam and a rod, allowing the rod to be inserted into the ground to increase the overall stability of the device and improve its practicality. The storage mechanism can classify and store the tested formwork, making it easy for workers to quickly retrieve it, thus improving the device's practicality. The testing mechanism can display the maximum pressure that the formwork can withstand in digital form, making it easier for workers to read and use the data, further improving the device's practicality.

[0004] Based on the above, existing template support strength testing devices mostly use a vertical pressure mechanism to apply load to the template sample and obtain the template's load-bearing data through a pressure acquisition component. During the testing process, when the pressure plate applies downward pressure, the template is prone to local breakage, lateral slippage, or even fragmentation and splashing under the load. Most existing devices rely on manually setting up protective baffles or operating without protection, which is not only cumbersome to operate, but also difficult to form an effective shield at the moment of pressure application. The flying debris can easily injure operators and damage testing components, posing a significant safety hazard. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a device for testing the strength of formwork supports in building engineering. This addresses the issue that existing formwork support strength testing devices often employ a vertical pressure mechanism to apply load to the formwork sample, acquiring load-bearing data through a pressure acquisition component. During the testing process, when the pressure plate applies downward pressure, the formwork is prone to localized cracking, lateral slippage, or even splintering and splashing under the load. Existing devices mostly rely on manually setting up protective barriers or operate without any protection, which is not only cumbersome but also makes it difficult to effectively shield the sample during pressure application. Furthermore, the splashing of debris can easily injure operators and damage testing components, posing significant safety hazards.

[0006] The purpose and effectiveness of this utility model for testing the strength of formwork supports in building engineering are achieved through the following specific technical means:

[0007] A device for testing the strength of formwork supports in building engineering includes a testing platform, a transmission support, drive screws, a positioning auxiliary mechanism, protective support plates, and a protective auxiliary mechanism. The transmission support is slidably mounted above the testing platform. Two drive screws are rotatably connected to the left and right sides of the upper end of the testing platform, respectively, with their top ends coaxially fixed to the output shaft of a drive motor. The positioning auxiliary mechanism is located below the drive screws. The positioning auxiliary mechanism includes two positioning clamps, slidably mounted on the front and rear sides of the upper end of the testing platform, with both ends of each clamp threaded to a double-ended screw. Two protective support plates are hinged to the testing platform via connecting shafts. A spiral spring is fixedly connected between the connecting shafts and the testing platform. The protective auxiliary mechanism is located between the protective support plates and the drive screws.

[0008] Furthermore, a detection pressure plate is fixedly connected to the bottom end face of the transmission bracket; a pressure sensor is provided at the upper end of the detection pressure plate; a digital display screen is fixedly connected to the top end face of the transmission bracket; the digital display screen is electrically connected to the pressure sensor; transmission support plates are fixedly connected to the left and right sides of the transmission bracket; the transmission support plate on the same side is threadedly connected to the drive screw through a threaded pair.

[0009] Furthermore, the positioning auxiliary mechanism includes: a double-ended screw, wherein two double-ended screws are provided, and the two double-ended screws are rotatably connected to the left and right sides of the detection operation table respectively; the double-ended screws on the same side are connected to the drive screw through a bevel gear transmission assembly.

[0010] Furthermore, the positioning auxiliary mechanism also includes: an auxiliary frame plate, which is slidably connected to the positioning clamping plate via multiple connecting guide posts; and an elastic connector is fixedly connected between the connecting guide posts and the positioning clamping plate.

[0011] Furthermore, the protective auxiliary mechanism includes: a transmission shaft, a drive rack, and a drive gear. There are two transmission shafts, which are rotatably connected to the left and right sides of the testing operation table, respectively. There are two drive racks, which are fixedly connected to the left and right ends of the transmission bracket, respectively. There are two drive gears, which are coaxially fixedly connected to the two transmission shafts, respectively. The drive gears on the same side mesh with the drive racks.

[0012] Furthermore, the protective auxiliary mechanism also includes: a transmission worm and a transmission worm wheel. The transmission worm is provided in two sets, and the two sets of transmission worms are coaxially fixedly connected to the front and rear ends of the transmission support shaft respectively. The pitch of the transmission worms on the front and rear sides is the same but the direction of rotation is opposite. The transmission worm wheel is provided in two sets, and the two sets of transmission worm wheels are coaxially fixedly connected to the two connecting support shafts respectively. The transmission worm wheel on the same side meshes with the transmission worm.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention effectively solves the problems of cumbersome and untimely protection in existing devices by setting up positioning and protective auxiliary mechanisms. It avoids lateral slippage of the template during pressurization and prevents squeezing damage to the template during positioning through the buffering effect of the elastic connector. At the same time, the sliding of the transmission bracket during pressurization drives the protective auxiliary mechanism, which in turn drives the protective support plates on both sides to rotate upward around the connecting support axis. At the moment when the detection pressure plate contacts the template and applies load, the protective shielding is completed, effectively blocking the flying debris caused by template breakage, avoiding injury to operators and damage to detection components such as pressure sensors and digital displays. After the detection is completed, the protective support plates automatically rotate downward without manual intervention, which simplifies the operation process and improves the safety and convenience of the detection process.

[0015] This invention achieves three simultaneous actions—vertical pressurization of the transmission bracket, lateral positioning of the positioning clamp, and flipping protection of the protective support plate—by using a single drive motor to rotate the drive screw. This eliminates the need for multiple additional drive mechanisms, simplifying the overall structure of the device and reducing manufacturing costs and maintenance difficulty. Furthermore, it eliminates the tedious steps of manual positioning and erection of protective barriers. Workers only need to place the template to be tested on the testing platform and start the drive motor to complete the entire testing process, significantly shortening the testing time for a single template and improving testing efficiency. It is particularly suitable for strength testing of batch templates in construction projects. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a device for testing the strength of formwork supports in building engineering, including a testing operating table 1, a transmission support 2, a drive screw 3, and a positioning auxiliary mechanism. The transmission support 2 is slidably mounted above the testing operating table 1. Two drive screws 3 are provided, and the two drive screws 3 are rotatably connected to the left and right sides of the upper end of the testing operating table 1, respectively. The top ends of the drive screws 3 are coaxially and fixedly connected to the output shaft of the drive motor. The positioning auxiliary mechanism is located below the drive screws 3. The positioning auxiliary mechanism includes two positioning clamps 4, which are slidably mounted on the front and rear sides of the upper end of the testing operating table 1, respectively. The two ends of the positioning clamps 4 are threadedly connected to the double-ended screw 401 through threaded pairs.

[0027] The transmission bracket 2 has a detection plate 201 fixedly connected to its bottom end face; a pressure sensor 202 is provided on the upper end of the detection plate 201; a digital display screen 203 is fixedly connected to the top end face of the transmission bracket 2; the digital display screen 203 is electrically connected to the pressure sensor 202; transmission support plates 204 are fixedly connected to the left and right sides of the transmission bracket 2; the transmission support plate 204 on the same side is threadedly connected to the drive screw 3 through a threaded pair.

[0028] The positioning auxiliary mechanism includes a double-ended screw 401. There are two double-ended screws 401, which are rotatably connected to the left and right sides of the detection operation table 1 respectively. The double-ended screw 401 on the same side is connected to the drive screw 3 through a bevel gear transmission assembly 402.

[0029] The positioning auxiliary mechanism also includes: an auxiliary frame plate 403, which is slidably connected to the positioning clamping plate 4 via multiple connecting guide posts 404; and an elastic connector 405 is fixedly connected between the connecting guide posts 404 and the positioning clamping plate 4.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In use, the template is placed on the upper end of the testing platform 1. When the drive motor is started and the screw 3 is driven to rotate, the transmission support plate 204 drives the transmission bracket 2 to slide downward. During the sliding of the transmission bracket 2, the testing pressure plate 201 slides downward synchronously and is squeezed. The pressure sensor 202 detects the pressure applied by the testing pressure plate 201 to the template to be tested, and the test data is displayed on the digital display screen 203. During the rotation of the drive screw 3, the double-headed screw 401 is driven to rotate through the transmission of the bevel gear transmission assembly 402. During the rotation of the double-headed screw 401, the positioning clamps 4 on both sides slide inward synchronously. During the relative sliding of the positioning clamps 4 on both sides, the auxiliary frame plate 403 contacts the template and slightly presses against the template to prevent the template from slipping or flying off during the contact between the testing pressure plate 201 and the template.

[0032] Example 2:

[0033] As attached Figure 3 To be continued Figure 5 As shown:

[0034] Based on Embodiment 1, it also includes a protective support plate 5 and a protective auxiliary mechanism. There are two protective support plates 5, and the two protective support plates 5 are respectively hinged to the detection operating table 1 through a connecting support shaft 501. A spiral spring 502 is fixedly connected between the connecting support shaft 501 and the detection operating table 1. The protective auxiliary mechanism is set between the protective support plate 5 and the drive screw 3.

[0035] The protective auxiliary mechanism includes: a transmission shaft 6, a drive rack 601, and a drive gear 602. There are two transmission shafts 6, which are rotatably connected to the left and right sides of the testing operation table 1, respectively. There are two drive racks 601, which are fixedly connected to the left and right ends of the transmission bracket 2, respectively. There are two drive gears 602, which are coaxially fixedly connected to the two transmission shafts 6, respectively. The drive gears 602 on the same side mesh with the drive racks 601.

[0036] The protective auxiliary mechanism also includes: a transmission worm 603 and a transmission worm wheel 604. Two sets of transmission worm 603 are provided, and the two sets of transmission worm 603 are coaxially fixedly connected to the front and rear ends of the transmission support shaft 6, respectively. The pitch of the transmission worm 603 on the front and rear sides is the same but the direction of rotation is opposite. Two sets of transmission worm wheels 604 are provided, and the two sets of transmission worm wheels 604 are coaxially fixedly connected to the two connecting support shafts 501, respectively. The transmission worm wheel 604 on the same side meshes with the transmission worm 603.

[0037] The specific usage and function of this embodiment are as follows:

[0038] In use, as the transmission bracket 2 slides downward, the drive rack 601 drives the drive gear 602 and the transmission shaft 6 to rotate. As the transmission shaft 6 rotates, the transmission worm 603 drives the transmission worm wheel 604 to rotate. When the transmission worm wheel 604 rotates, it drives the connecting shaft 501 to rotate. When the connecting shaft 501 rotates, the protective support plates 5 on both sides flip upward synchronously, achieving effective protection when the template is being tested. After the test is completed, when the transmission bracket 2 slides upward, the protective support plates 5 flip downward synchronously, making it easy to place the template to be tested on the upper end of the testing operation table 1 for testing.
