Description

Technical Field

[0001] This invention relates to the field of strength testing technology, specifically to a strength testing device for prefabricated building structures. Background Technology

[0002] Prefabricated construction is a modern construction method that transfers a large amount of on-site work in the traditional construction process to factories. Building components are prefabricated in factories and then transported to the construction site for assembly. This method can greatly improve construction speed, reduce construction cycle and cost. However, after prefabricated stair slabs are pre-formed, it is sometimes necessary to test their strength to determine whether the strength of the stair slabs meets the requirements. Existing strength testing equipment usually applies a certain pressure directly to the building structure to determine its strength. However, stair slabs are usually set at an angle during assembly. If pressure is applied directly to the stair slabs for testing, the method of applying pressure will be different from the actual load-bearing method of the stair slabs, and the test results may be somewhat biased, resulting in relatively poor testing effect. Summary of the Invention

[0003] The purpose of this invention is to provide a prefabricated building structure strength testing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A prefabricated building structure strength testing device includes a support module, a guide module, a winding module one, and a winding module two.

[0007] Furthermore, the detection rod is provided with several locking slots, and the mounting base is screwed with several positioning screws corresponding to the detection rod.

[0008] Preferably, the lifting mechanism is provided with a connecting seat that is rotatably connected to the L-shaped seat II. Both ends of the connecting seat are fixedly connected to support plates. The top of the guide component is set on the adjacent support plate. The bottom surface of the L-shaped seat II is in contact with the connecting seat. The support plate and the fixed plate are parallel to each other.

The inner side of the fixed frame is slidably connected to the side of the connecting seat, and the opposing surfaces of the two support plates are slidably connected to the side of the fixed frame. Both adjusting screws are rotatably connected to the inner side of the fixed frame, and both adjusting screws are screwed into the connecting seat. The second dual-axis motor is mounted on the inner side of the top of the fixed frame; Both drive shafts are rotatably connected to the inner side of the fixed frame, and both output ends of the dual-axis motor are connected to the ends of the adjacent drive shafts. Four bevel gears are fixedly sleeved on the ends of two transmission shafts and the tops of two adjusting screws, and adjacent bevel gears mesh for transmission.

[0009] Furthermore, the support module includes a support frame, an adjustment frame, and an L-shaped seat; A support frame is fixedly connected to the bottom surface of the support frame, a limit plate is fixedly connected to the inner side of the support frame, and the support assembly is set on the top of the support frame; The adjusting frame is slidably connected to the support frame. Several rollers are provided at the bottom of the adjusting frame. The lifting mechanism is located at the top of the adjusting frame. The fixed frame is fixedly connected to the top surface of the adjusting frame. The L-shaped seat is rotatably connected inside the support frame, and the bottom surface of the L-shaped seat contacts the top surface of the limiting plate.

[0010] Furthermore, a dual-axis motor is fixedly connected inside the adjustment frame. Both output ends of the dual-axis motor are driven by a transmission shaft that is rotatably connected to the adjustment frame. The adjustment frame is rotatably connected to two adjusting screws that are screwed into the support frame. Both the transmission shaft and the adjusting screws are fixedly fitted with bevel gears, and adjacent bevel gears mesh and drive each other. The threads of the two adjusting screws are in opposite directions.

[0011] Preferably, the winding module one and the winding module two have the same structure. Two connecting ropes are fixedly connected to both sides of the detection frame. Guide tubes that are fixedly connected to the inner side of the adjacent fixed plate are fixedly connected to both ends of the limiting frame. The connecting ropes pass through the inside of the adjacent guide tubes. The winding module includes a winding frame, two power motors, and two winding rods; The winding frame is fixedly connected to the adjusting frame; Both power motors are fixedly connected inside the take-up frame; Both take-up rods are rotatably connected inside the take-up frame.

The end of the connecting rope extends into the corresponding take-up frame and is wound around the side of the adjacent take-up rod. The four connecting ropes are respectively wound around the two take-up rods of take-up module one and take-up module two.

[0012] Preferably, the support assembly includes a fixed rod, a sliding rod, and a hydraulic rod. The fixing rod is fixedly connected to the support frame; The sliding rod is slidably connected to the fixed rod, and the bottom of the guide assembly is set on the sliding rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The lifting mechanism includes an L-shaped seat II. After the prefabricated stair slab is hoisted onto the top of the support module, the end of the stair slab aligns with the interior of the L-shaped seat II. The lifting mechanism then moves the L-shaped seat II upward, tilting the stair slab and simultaneously tilting the guide component. The detection module can move along the guide component, allowing it to gradually perform strength tests on several steps of the stair slab. By tilting the stair slab, the downward pressure applied to the steps is relatively close to the actual load-bearing capacity of the stair slab, thus closely approximating the load-bearing capacity of the stair slab. This helps reduce the deviation of the test results and improves the testing effect. The tilt angle of the guide component is approximately the same as the tilt angle of the stair slab. As the detection module moves along the guide component to test each step of the stair slab, the output end of the hydraulic rod II can move approximately a fixed length and apply a fixed pressure, which is beneficial for continuous testing of the steps.

[0015] A return spring is fixedly connected to the bottom of the abutment plate, and the hydraulic rod two can limit the position of the abutment plate. The abutment plate can apply a certain pressure to the connecting frame through the return spring. In this way, when the drive motor drives the connecting shaft to rotate, causing the mounting seat to drive the detection rod to rotate, and the detection module to move along the guide component, several detection rods can be abutted against several steps of the stair tread in sequence, thereby enabling continuous detection of the stair tread. At the same time, after rotating one detection rod to a vertical position, the hydraulic rod two can drive the abutment plate to move downward, so that the bottom surface of the abutment plate contacts the top surface of the baffle. Then, the hydraulic rod two applies relatively large pressure to the mounting seat and the detection rod, thereby performing a relatively large strength test on the stair tread.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-10 In this embodiment of the invention, a prefabricated building structure strength testing device includes a support module 100, a guide module 200, a first winding module 400, and a second winding module 500. The guide module 200 includes a lifting mechanism 220 and two support components 210. A testing module 300 is disposed inside the guide module 200. The testing module 300 includes a limiting frame 310, a testing frame 320 slidably connected to the limiting frame 310, and a connecting frame 330 slidably connected inside the testing frame 320. The internal structure 0 is equipped with a hydraulic rod 324, the internal structure 220 is equipped with an L-shaped seat 250, the two support components 210 are each equipped with two guide components 240, the two ends of the limit frame 310 are fixedly connected with fixed plates 311, the fixed plates 311 are rotatably connected with two sliding frames 312 that are slidably connected to the adjacent guide components 240, the connecting frame 330 is fixedly connected with an abutment frame 331, the abutment frame 331 is rotatably connected with a mounting seat 340, and the mounting seat 340 is equipped with several detection rods 350; The support module 100 supports the support assembly 210 and the lifting mechanism 220. The lifting mechanism 220 can adjust the height of the L-shaped seat 250. Four guide components 240 are respectively arranged on opposite sides of two support assemblies 210. The four guide components 240 are arranged in pairs and are parallel to each other. The support assembly 210 is parallel to the fixed plate 311, and the fixed plate 311 is perpendicular to the limiting frame 310. Two limiting seats 325 are fixedly connected to the two sides of the limiting frame 310 and are slidably connected to the inner side of the limiting frame 310. The inner side of the limiting seat 325 is rotatably connected to the limiting seat. The rolling block contacts the inner side of the frame 310. The detection frame 320 and the limiting seat 325 can be translated along the inside of the limiting frame 310, so that the rolling block moves along the inside of the limiting frame 310. The mounting seat 340 is located at the bottom side of the connecting frame 330. The fixing plate 311, a set of two guide components 240, and the support component 210 can form a parallelogram. When the sliding frame 312 slides along the guide component 240, since the sliding frame 312 is rotatably set on the fixing plate 311, the fixing plate 311 and the support component 210 can be kept parallel, so that the fixing plate 311 is kept vertical, thereby maintaining the angle between the limiting frame 310 and the detection frame 320.

[0020] The detection rod 350 has several slots 351, and the mounting base 340 is screwed with several positioning screws 341 corresponding to the detection rod 350. The detection rod 350 is slidably disposed inside the mounting base 340, and the ends of the positioning screws 341 extend into the adjacent slots 351.

[0021] Specifically, after the prefabricated stair tread is hoisted onto the top of the support module 100, the end of the stair tread can be aligned with the interior of the L-shaped seat 250. The lifting mechanism 220 can move the L-shaped seat 250 upward, thereby raising the end of the prefabricated stair tread and tilting it. Simultaneously, the guide component 240 can be tilted, with its tilt angle as close as possible to that of the stair tread. This allows the detection module 300 to move along the guide component 240, gradually passing through several steps of the stair tread. The hydraulic rod 324 can then move the connecting frame 330 downward. The connecting frame 330 can then move the mounting base 340 downward via the abutment frame 331. The mounting base 340 can then apply pressure to the stair tread via the detection rod 350 at its bottom. The force applied to the stair slab is used to test its strength. By tilting the stair slab, the downward pressure applied to the steps is relatively close to the actual load-bearing method of the stair slab, thus closely approximating the load-bearing method of the stair slab. This helps to reduce the deviation of the test results and improve the test effect. By making the tilt angle of the guide component 240 approximately the same as the tilt angle of the stair slab, when the test module 300 moves along the guide component 240 to test each step of the stair slab, after the test module 300 moves along the guide component 240 by a fixed angle, the distance between the limit frame 310 and each step is approximately the same. This allows the output end of the hydraulic rod 324 to move approximately a fixed length, so that the pressure applied each time is approximately the same, which is beneficial for continuous testing of the steps. The positioning screw 341 can be rotated as needed to disengage it from the adjacent slot 351, allowing the detection rod 350 to slide within the mounting base 340. The extension length of the detection rod 350 can be adjusted as needed to adapt the distance between the ends of two adjacent detection rods 350 to the stair spacing, which is beneficial for inspecting stair treads of different sizes. The detection rod 350 can also be replaced as needed. After adjustment or replacement, the positioning screw 341 can be rotated in the opposite direction to re-insert it into the corresponding slot 351, thereby limiting the detection rod 350 through the positioning screw 341. Example 1

[0022] like Figure 9-10 As shown, in this embodiment, a drive motor 321 is fixedly connected inside the detection frame 320, and a drive shaft 322 that is rotatably connected to the output end of the drive motor 321 is driven by the drive shaft 322 that is rotatably connected to the detection frame 320. An elliptical rod 323 is fixedly connected to the drive shaft 322. The connecting frame 330 is rotatably connected to the connecting shaft 332, which is fixedly connected to the mounting base 340. The connecting frame 330 is also rotatably connected to the positioning shaft 334, which is slidably connected to the elliptical rod 323. Both the connecting shaft 332 and the positioning shaft 334 are fixedly sleeved with bevel gears 333, and the two bevel gears 333 mesh for transmission. The positioning shaft 334 has an elliptical groove inside. The side of the elliptical rod 323 is slidably connected to the inner side of the elliptical groove. The end of the connecting shaft 332 passes through the inside of the abutment frame 331 and is fixed on the side of the mounting base 340. The drive motor 321 is located at the top inside the detection frame 320, and the connecting shaft 332 is located at the bottom inside the connecting frame 330. When the connecting frame 330 moves downward along the inside of the detection frame 320, the connecting frame 330 can drive the positioning shaft 334 to move, thereby causing the positioning shaft 334 to move on the elliptical rod 323. A sliding abutment plate 336 is slidably connected inside the connecting frame 330. The output end of the hydraulic rod 324 is connected to the abutment plate 336. A return spring 337, which is fixedly connected to the connecting frame 330, is fixedly connected to the bottom of the abutment plate 336. A stop 335 is fixedly connected inside the connecting frame 330. The stop 335 is located at the bottom of the abutment plate 336. The return spring 337 and the positioning shaft 334 both pass through the inside of the stop 335. The positioning shaft 334 passes through the inside of the abutment plate 336. The abutment plate 336 is located between the hydraulic rod 324 and the return spring 337.

[0023] In practical implementation, hydraulic rod 324 can restrict the position of abutment plate 336. Abutment plate 336 can apply a certain pressure to connecting frame 330 through return spring 337. Connecting frame 330 can apply a certain pressure to mounting base 340 through abutment frame 331, thereby causing the detection rod 350 at the bottom of mounting base 340 to abut against the stair slab for strength testing. The position of abutment plate 336 can be adjusted by hydraulic rod 324, thereby adjusting the pressure on the stair slab. Drive shaft 322 can be rotated by drive motor 321, which can drive elliptical rod 323 to rotate. Since the cross-section of elliptical rod 323 is elliptical, elliptical rod 323 can drive positioning shaft 334 to rotate. Positioning shaft 334 can drive connecting shaft 332 to rotate through two bevel gears 333. Connecting shaft 332 can drive mounting base 340 to rotate. The mounting base 340 rotates within the abutment frame 331, and the mounting base 340 can drive the detection rods 350 to rotate. Thus, when the detection module 300 is moved along the guide assembly 240, the rotation of several detection rods 350 allows them to sequentially abut against several steps of the stair tread, thereby enabling continuous detection of the stair tread. After the detection rods 350 at the bottom of the mounting base 340 are rotated to a vertical position, the hydraulic rod 324 can drive the abutment plate 336 to move downward, so that the bottom surface of the abutment plate 336 contacts the top surface of the baffle 335. At this time, the hydraulic rod 324 can press the baffle 335 through the abutment plate 336, thereby pressing the connecting frame 330. The hydraulic rod 324 applies relatively large pressure to the mounting base 340 and the detection rods 350, enabling a relatively strong strength test of the stair tread.

[0024] like Figure 4-5 As shown, in this embodiment, the lifting mechanism 220 is provided with a connecting seat 230 that is rotatably connected to the L-shaped seat 250. Both ends of the connecting seat 230 are fixedly connected to the support plate 231. The top of the guide component 240 is set on the adjacent support plate 231. The bottom surface of the L-shaped seat 250 contacts the connecting seat 230. The side bend of the L-shaped seat 250 is rotatably connected to the inner side of the connecting seat 230 through a shaft. The bottom surface of the L-shaped seat 250 contacts the inside of the connecting seat 230. In this way, the rotation angle of the L-shaped seat 250 can be limited by the connecting seat 230, so that the inside of the L-shaped seat 250 faces upward, which makes it easy to place the end of the stair tread inside the L-shaped seat 250. The support plate 231 and the fixed plate 311 are parallel to each other. The lifting mechanism 220 includes a fixed frame 221, two adjusting screws 222, a dual-shaft motor 223, two transmission shafts 224, and four bevel gears 225; The inner side of the fixed frame 221 is slidably connected to the side of the connecting seat 230. The opposite surfaces of the two support plates 231 are slidably connected to the side of the fixed frame 221. The two adjusting screws 222 are rotatably connected to the inner side of the fixed frame 221 and screwed into the connecting seat 230. The dual-axis motor 223 is set on the top inner side of the fixed frame 221. The two transmission shafts 224 are rotatably connected to the inner side of the fixed frame 221. The two output ends of the dual-axis motor 223 are connected to the ends of the adjacent transmission shafts 224. The four bevel gears 225 are respectively fixedly sleeved on the ends of the two transmission shafts 224 and the tops of the two adjusting screws 222. The two adjacent bevel gears 225 mesh and drive each other. The threads of the two adjusting screws 222 are opposite, so that the connecting seat 230 can move smoothly up or down along the inside of the fixed frame 221.

[0025] In practice, after the end of the stair tread is placed inside the L-shaped seat 250, the two drive shafts 224 can be rotated by the dual-shaft motor 223. The drive shafts 224 can rotate by the two adjacent bevel gears 225. When the adjustment screws 222 rotate, the connecting seat 230 can move upward along the inside of the fixed frame 221. The connecting seat 230 can drive the support plate 231 and the L-shaped seat 250 to move upward, so that the L-shaped seat 250 lifts the end of the stair tread and puts the stair tread in an inclined state.

[0026] like Figure 2-4 As shown, in this embodiment, the support module 100 includes a support frame 110, an adjustment frame 120, and an L-shaped seat 130; A support frame 111 is fixedly connected to the bottom surface of the support frame 110, and a limit plate 112 is fixedly connected to the inner side of the support frame 110. A support assembly 210 is set on the top of the support frame 110. An adjusting frame 120 is slidably connected to the support frame 110. Several rollers are provided at the bottom of the adjusting frame 120. The support frame 111 can support the support frame 110, and the rollers can support the adjusting frame 120. A lifting mechanism 220 is set on the top of the adjusting frame 120. A fixed frame 221 is fixedly connected to the top surface of the adjusting frame 120. An L-shaped seat 130 is rotatably connected to the inside of the support frame 110. The bottom surface of the L-shaped seat 130 contacts the top surface of the limit plate 112. The side corner of the L-shaped seat 130 rotates with the inside of the support frame 110 through a shaft. The rotation angle of the L-shaped seat 130 can be limited by the limit plate 112, so that the inside of the L-shaped seat 130 faces upward. A dual-axis motor 121 is fixedly connected inside the adjusting frame 120. Both output ends of the dual-axis motor 121 are connected to a drive shaft 122 that is rotatably connected to the adjusting frame 120. The adjusting frame 120 is rotatably connected to two adjusting screws 124 that are screwed into the support frame 110. The support frame 110 and the adjusting frame 120 can be connected through the adjusting screws 124. Both the drive shaft 122 and the adjusting screw 124 are fixedly sleeved with bevel gears 123, and two adjacent bevel gears 123 mesh and drive each other. The threads of the two adjusting screws 124 are in opposite directions.

[0027] In practice, one end of the stair tread is placed inside the L-shaped seat 130, and the other end is placed inside the L-shaped seat 250. The L-shaped seat 250 can then be moved upward by the lifting mechanism 220, lifting the other end of the stair tread upward. At the same time, the dual-shaft motor 121 drives the transmission shaft 122 to rotate. The transmission shaft 122 can drive the corresponding adjusting screw 124 to rotate through two adjacent bevel gears 123. When the adjusting screw 124 rotates, it can move along the inside of the support frame 110, causing the adjusting frame 120 to move towards the support frame 110. This reduces the distance between the support assembly 210 and the lifting mechanism 220, keeping the end of the stair tread inside the L-shaped seat 250. Example 2

[0028] Based on Example 1, such as Figure 6 As shown, in this embodiment, the support assembly 210 includes a fixed rod 211, a sliding rod 212, and a hydraulic rod 213; The fixed rod 211 is fixedly connected to the support frame 110, the sliding rod 212 is slidably connected to the fixed rod 211, the bottom of the guide assembly 240 is set on the sliding rod 212, and two guide wheels are set on both the sliding rod 212 and the support plate 231. The hydraulic rod 213 is set inside the fixed rod 211, and the output end of the hydraulic rod 213 is connected to the sliding rod 212 in a transmission manner. The hydraulic rod 213 is located inside the fixed rod 211 and the sliding rod 212. The fixed rod 211 can support the sliding rod 212 through the hydraulic rod 213, thereby supporting the bottom end of the guide rod 241. The guide assembly 240 includes a first guide rod 241 and a second guide rod 242; Guide rod 1 241 is rotatably connected to the adjacent sliding rod 212, and guide rod 242 is slidably connected to guide rod 1 241. Guide rod 242 can slide inside guide rod 1 241. The top end of guide rod 242 is rotatably connected to the adjacent support plate 231, and the support plate 231 can support the top end of guide rod 242.

[0029] In specific implementation, when the lifting mechanism 220 raises the connecting seat 230 and the L-shaped seat 250, the connecting seat 230 can drive the support plate 231 to move upward, and the support plate 231 can drive the top of the guide rod 242 to move upward. When the adjusting frame 120 drives the lifting mechanism 220 to move towards the support frame 110, the end of the support plate 231 can move towards the support frame 110. In this way, the support plate 231 can drive the top of the guide rod 242 to move towards the support frame 110, so that the guide rod 242 slides within the guide rod 241. After the L-shaped seat 250 raises the stair tread, the sliding rod 212 can be moved upward or downward by the hydraulic rod 213, so that the bottom of the guide rod 241 moves upward or downward, adjusting the height of the bottom of the guide rod 241. Then, the tilt angle of the guide assembly 240 can be adjusted according to the tilt angle of the stair tread, which is convenient for the detection of stair treads of different sizes.

[0030] like Figure 3 and Figure 8 As shown, in this embodiment, the winding module 1 400 and the winding module 2 500 have the same structure. Two connecting ropes 600 are fixedly connected to both sides of the detection frame 320. The limiting frame 310 is fixedly connected to both ends of the guide tube 313 which is fixedly connected to the inner side of the adjacent fixed plate 311. The connecting ropes 600 pass through the interior of the adjacent guide tube 313. The winding module 400 includes a winding frame 410, two power motors 420, and two winding rods 430; The take-up frame 410 is fixedly connected to the adjusting frame 120. Two power motors 420 are fixedly connected inside the take-up frame 410. Two take-up rods 430 are rotatably connected inside the take-up frame 410. The output end of the power motor 420 is connected to the end of the adjacent take-up rod 430. The end of the connecting rope 600 extends into the corresponding take-up frame 410 and is wound around the side of the adjacent take-up rod 430. The four connecting ropes 600 are wound around the two take-up rods 430 of the take-up module 1 400 and the take-up module 2 500 respectively. The connecting ropes 600 pass around two adjacent guide wheels. The connecting ropes 600 pass through the guide cylinder 313 and the two guide wheels in sequence, and then extend into the take-up frame 410 of the corresponding take-up module 1 400 or take-up module 2 500 and are wound around the take-up rod 430 of the take-up module 1 400 or take-up module 2 500.

[0031] In practical implementation, when the stair tread needs to be inspected, the two motors 420 of winding module one 400 and winding module two 500 can be started. The motors 420 can drive the winding rods 430 to rotate, causing the two winding rods 430 of winding module one 400 to simultaneously release the connecting rope 600, and the two winding rods 430 of winding module two 500 to simultaneously wind up the connecting rope 600. In this way, the detection module 300 can be pulled diagonally downward along the guide assembly 240 by the connecting rope 600 diagonally below it. After the inspection is completed, the two winding rods 430 of winding module one 400 can simultaneously wind up the connecting rope 600, and the two winding rods 430 of winding module two 500 can simultaneously release the connecting rope 600. In this way, the detection module 300 can be pulled diagonally upward along the guide assembly 240 by the connecting rope 600 diagonally above it. The device moves diagonally upwards. During testing, one motor 420 of winding module 1 (400) and winding module 2 (500) drives the winding rod 430 to rotate forward. One motor 420 of winding module 1 (400) and winding module 2 (500) is located at the same end of the limiting frame 310, and the other motor 420 of winding module 1 (400) and winding module 2 (500) drives the winding rod 430 to rotate in the opposite direction. This causes one winding rod 430 of winding module 1 (400) and winding module 2 (500) to simultaneously wind up the adjacent connecting rope 600, while the other winding rod 430 of winding module 1 (400) and winding module 2 (500) simultaneously releases the connecting rope 600. In this way, the two connecting ropes 600 at one end of the limiting frame 310 can pull the detection frame 320 to slide inside the limiting frame 310, adjusting the position of the detection frame 320 relative to the limiting frame 310, and performing strength testing on different positions of the stair slab.
