Description

Technical Field

[0001] The present application relates to the technical field of prefabricated ground-connected walls, and in particular to a prefabricated ground-connected wall pre-assembly test tool and a test method. Background Art

[0002] Prefabricated ground-connected walls, that is, multiple ground-connected walls are prefabricated in advance according to the installation location, and splicing structures are set on both sides of the ground-connected walls. The splicing structure includes a splicing flange and a splicing groove. The splicing flange and the splicing groove are respectively set on both sides of the prefabricated ground-connected wall. The prefabricated ground-connected wall is transported to the installation location for direct installation and splicing, which greatly improves the installation speed and construction efficiency of the ground-connected wall.

[0003] Although the prefabricated ground-connected walls are produced in the same batch, processing errors may still occur, resulting in multiple prefabricated ground-connected walls getting stuck due to differences in processing accuracy of the splicing structures when they are spliced. This requires construction workers to temporarily grind the splicing structures of the prefabricated ground-connected walls so that the prefabricated ground-connected walls can be spliced ​​together, which delays the construction speed. Therefore, a prefabricated ground-connected wall pre-assembly test tool and test method are needed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a prefabricated ground-connected wall pre-assembly test tool and test method, which is used to solve the technical problem of low construction efficiency caused by inaccurate splicing structure of prefabricated ground-connected walls in the prior art.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: a prefabricated ground-connected wall pre-assembly test tool, including a flange detection platform and a groove detection platform, the flange detection platform and the groove detection platform are arranged opposite to each other with a gap between them, a detection groove is provided on a side of the flange detection platform opposite to the groove detection platform, and the detection groove is arranged along the length direction of the flange detection platform, a detection flange is provided on a side of the groove detection platform opposite to the flange detection platform, and a walking device is provided on the bottom surface of the flange detection platform and the groove detection platform, and a connecting rod is fixed between the walking device of the flange detection platform and the walking device of the groove detection platform.

[0006] By adopting the above technical scheme, the prefabricated ground connection wall is hoisted into a horizontal straight state, and then the splicing flange of the prefabricated ground connection wall is aligned with the flange detection platform, and the splicing groove is aligned with the groove detection platform, and then the flange detection platform and the groove detection platform are pushed to move toward the prefabricated ground connection wall, so that the splicing flange is inserted into the detection groove, and the detection flange is inserted into the splicing groove, and then the flange detection platform and the groove detection platform are continued to be pushed toward the prefabricated ground connection wall, so that the splicing flange and the splicing groove pass through the detection groove and the detection flange. If the flange detection platform and the groove detection platform are stuck during the movement, it proves that the splicing structure size of the prefabricated ground connection wall is wrong and needs to be corrected. If the flange detection platform and the groove detection platform pass through the entire prefabricated ground connection wall smoothly, it proves that the ground connection wall does not need to be corrected and can be spliced ​​and used. In this way, when the prefabricated ground connection wall is manufactured, simulated splicing can be performed to determine whether the prefabricated ground connection wall can be spliced ​​normally, so that there will be no unsuccessful splicing during construction, and the splicing of the prefabricated ground connection wall during normal construction is prevented from getting stuck, thereby improving the construction efficiency.

[0007] Furthermore, the walking device includes a support rod and a moving wheel, the moving wheel is arranged at the bottom end of the support rod and is rotatably connected to the support rod, and the circumferential surface of the moving wheel contacts the bottom surface, and the walking device is provided with a plurality of bottom surfaces respectively located at both ends of the flange detection platform and the bottom surfaces at both ends of the groove detection platform.

[0008] Furthermore, the length of the flange detection platform and the groove detection platform is longer than that of the prefabricated ground connection wall. The upper and lower surfaces of the flange detection platform are provided with a plurality of detection columns for detecting whether the width of the spliced ​​flange is qualified. The detection columns are inserted into the flange detection platform and pass through the detection groove. The plurality of detection columns are arranged along the length direction of the flange detection platform.

[0009] By adopting the above technical solution, although the flange detection platform and the groove detection platform can detect whether the prefabricated ground connection wall can be spliced, the splicing flange with a width smaller than the detection groove can also pass through the detection groove, which results in a gap between the splicing flange and the splicing groove after the prefabricated ground connection wall is spliced. This gap will affect the stability of the entire prefabricated ground connection wall structure, causing air to enter the entire prefabricated ground connection wall structure after the prefabricated ground connection wall is installed. The setting of the detection column solves this technical problem. Through the setting of the detection column, the detection personnel push the flange The inspection table and the groove inspection table are moved to completely block the two sides of the prefabricated floor connection wall, and then the inspection personnel push the inspection column into the flange inspection table. At this time, if the splicing flange of the prefabricated floor connection wall completely conforms to the inspection groove, the inspection column will not be retracted into the flange inspection table. If the splicing flange width of the prefabricated floor connection wall is smaller than the inspection groove, the inspection column will be retracted into the flange inspection table. In this way, the inspection personnel can distinguish whether the splicing flange width of the prefabricated floor connection wall is qualified, and the inspection personnel can also determine the specific location of the unqualified position, so that the inspection result of the flange inspection table is more accurate.

[0010] Furthermore, a vertical slide groove is provided on a side of the flange detection platform away from the groove detection platform, and an auxiliary device is provided on the flange detection platform for sliding connection with the flange detection platform through the slide groove.

[0011] Furthermore, the auxiliary device includes an upper pressing structure and a lower pressing structure, the upper pressing structure includes a sliding block located in a sliding groove, a vertical rod arranged at an end of the sliding block away from the sliding groove, and a pressure plate located directly above the flange detection platform, the vertical rod is perpendicular to the sliding block and fixedly connected to the sliding block, the pressure plate is fixedly connected to the vertical rod and a gap is left between the pressure plate and the upper surface of the flange detection platform, the pressure plate covers the upper surface of the flange detection platform, the structure of the lower pressing structure is the same as the upper pressing structure, but the lower pressing structure is based on the upper pressing structure and is mirrored below the flange detection platform with the center point of the end face of the flange detection platform as the midpoint, the pressure plate of the upper pressing structure and the pressure plate of the lower pressing structure are fixedly provided with a locking plate extending laterally to the outside of the flange detection platform on one side close to the vertical rod, and the two locking plates are provided with adjusting bolts that pass through the two locking plates and are threadedly connected to the locking plates.

[0012] By adopting the above-mentioned technical scheme, although the setting of the detection column makes the detection result of the flange detection platform more accurate, due to the long length of the prefabricated ground connection wall, the detection personnel need to push the detection column multiple times, which is very inconvenient. The setting of the auxiliary device solves this technical problem. Through the setting of the auxiliary device, when the detection personnel need to push the detection column, the pressure plate of the upper pressure structure and the pressure plate of the lower pressure structure are respectively pushed by turning the adjusting bolt to push the detection columns on the upper and lower surfaces of the flange detection platform. In this way, all the detection columns can be pushed at one time, which is convenient for the detection personnel to detect.

[0013] Furthermore, a number of rebound structures equal to the number of detection columns are provided between the pressure plate and the flange detection platform.

[0014] Furthermore, the rebound structure includes a rebound plate and a support spring, the support spring is located between the pressure plate and the rebound plate, one end of the support spring is fixedly connected to the rebound plate, and the other end is fixedly connected to the pressure plate, and the side of the rebound plate away from the support spring faces the detection column.

[0015] By adopting the above technical solution, although the setting of the auxiliary device can facilitate the inspection by the inspectors, pushing the inspection column by the pressure plate will cause the pressure plate to be unable to apply pressure to other inspection columns after one inspection column presses against the pressure plate, resulting in erroneous inspection results. The setting of the rebound structure solves this technical problem. When the inspector pushes the pressure plate, the pressure plate applies pressure to the inspection column through the rebound plate. After a rebound plate is pressed by a inspection column, it will shrink. When testing other rebound plates, they can continue to apply pressure to other inspection columns due to the setting of the support spring, thereby completing the inspection. The pressure plate can facilitate the inspection by the inspectors while not affecting the inspection structure.

[0016] Furthermore, one end of the flange detection platform and the groove detection platform located on the same side is connected to a limit rod.

[0017] By adopting the above technical solution, the limit rod is used to prevent the flange inspection platform and the groove inspection platform from moving too far when the inspector pushes them to move.

[0018] Furthermore, one end of the flange detection platform and the groove detection platform connected to the limit rod is provided with an insertion interface, and plug-in rods are extended on both sides of the limit rod, and the plug-in rods are plugged into the flange detection platform and the groove detection platform through the insertion interface.

[0019] By adopting the above technical solution, although the setting of the limit rod can prevent the inspectors from pushing the flange inspection platform and the groove inspection platform to move too far, the prefabricated floor connection wall that is longer than the flange inspection platform and the groove inspection platform needs to pass through the entire flange inspection platform and the groove inspection platform to detect its entire splicing structure during inspection. The setting of the limit rod makes it more troublesome to inspect the prefabricated floor connection wall that is longer than the flange inspection platform and the groove inspection platform. The setting of the plug-in rod solves this technical problem. Through the setting of the plug-in rod, the inspectors can adjust the distance between the limit rod and the flange inspection platform and the groove inspection platform according to the length of the prefabricated floor connection wall, so that the limit rod adapts to the length of the prefabricated floor connection wall, thereby improving the practicality and applicability of the limit rod.

[0020] A prefabricated ground-connected wall pre-assembly test method comprises the following steps: S1. The hoisted ground connecting wall is in a horizontal straight line state; S2, aligning the splicing flange of the prefabricated ground connection wall with the flange detection platform, aligning the splicing groove with the groove detection platform, and then pushing the flange detection platform and the groove detection platform to move toward the prefabricated ground connection wall; S3. Continue to push the flange detection platform and the groove detection platform until the flange detection platform and the groove detection platform completely block both sides of the prefabricated ground connecting wall; S4. Tighten the adjusting bolts so that the pressure plate of the upper pressure structure and the pressure plate of the lower pressure structure push the detection columns on the upper and lower surfaces of the flange detection platform respectively; S5. Observe whether the detection column is retracted into the flange detection platform. If so, repair the splicing flange of the prefabricated ground connection wall. If not, proceed to the next step. S6. Push the flange inspection platform and the groove inspection platform in the opposite direction to make the prefabricated floor connecting wall slide out from between the flange inspection platform and the groove inspection platform to complete the inspection.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the flange detection platform and the groove detection platform, the prefabricated ground connection wall is hoisted into a horizontal straight state, and then the splicing flange of the prefabricated ground connection wall is aligned with the flange detection platform, and the splicing groove is aligned with the groove detection platform, and then the flange detection platform and the groove detection platform are pushed to move toward the prefabricated ground connection wall, so that the splicing flange is inserted into the detection groove, and the detection flange is inserted into the splicing groove, and then the flange detection platform and the groove detection platform are continued to move toward the prefabricated ground connection wall, so that the splicing flange and the splicing groove pass through the detection groove and the detection flange. If the splicing flange and the splicing groove pass through the detection groove and the detection flange, the splicing flange and the detection groove are moved to the detection groove and the detection flange. If the flange detection station and the groove detection station get stuck during the process, it proves that the splicing structure size of the prefabricated ground connection wall is wrong and needs to be corrected. If the flange detection station and the groove detection station pass through the entire prefabricated ground connection wall smoothly, it proves that the ground connection wall does not need to be corrected and can be spliced ​​and used. In this way, when the prefabricated ground connection wall is manufactured, simulated splicing can be carried out to determine whether the prefabricated ground connection wall can be spliced ​​normally, so that there will be no unsuccessful splicing during construction, and the prefabricated ground connection wall can be prevented from getting stuck during normal construction, thereby improving the construction efficiency.

[0022] 2. Through the setting of the auxiliary device, when the inspector needs to push the inspection column, the pressure plate of the upper pressure structure and the pressure plate of the lower pressure structure are turned to push the inspection columns on the upper and lower surfaces of the flange inspection platform respectively by screwing the adjusting bolt. In this way, all the inspection columns can be pushed at one time, which is convenient for the inspector to detect.

[0023] 3. Through the setting of the rebound structure, when the inspector pushes the pressure plate, the pressure plate applies pressure to the detection column through the rebound plate. After a rebound plate is supported by a detection column, it will shrink. When testing other rebound plates, they can continue to apply pressure to other detection columns because of the setting of the supporting spring, thereby completing the detection. This makes it convenient for the inspector to detect while not affecting the purpose of the detection structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present application is further described in detail below in conjunction with the accompanying drawings.

[0027] Example, see Figure 1 A prefabricated ground-connected wall pre-assembly test tool comprises a flange detection platform 1 and a groove detection platform 2, the flange detection platform 1 and the groove detection platform 2 are arranged opposite to each other with a gap therebetween, a detection groove 10 is provided on a side of the flange detection platform 1 opposite to the groove detection platform 2, the detection groove 10 is arranged along the length direction of the flange detection platform 1, a detection flange 20 is arranged along the length direction of the groove detection platform 2 on a side of the groove detection platform 2 opposite to the flange detection platform 1, a walking device 3 is provided on the bottom surface of the flange detection platform 1 and the groove detection platform 2, a connecting rod 30 is fixedly provided between the walking device 3 of the flange detection platform 1 and the walking device 3 of the groove detection platform 2, the walking device 3 comprises a support rod 31 and a moving wheel 32, the moving wheel 32 is arranged at the bottom end of the support rod 31 and is rotatably connected to the support rod 31, and the circumferential surface of the moving wheel 32 contacts the bottom surface, and the walking device 3 is provided with a plurality of bottom surfaces respectively located at both ends of the flange detection platform 1 and the bottom surfaces at both ends of the groove detection platform 2.

[0028] The prefabricated ground connection wall is hoisted into a horizontal straight state, and then the splicing flange of the prefabricated ground connection wall is aligned with the flange detection platform 1, and the splicing groove is aligned with the groove detection platform 2, and then the flange detection platform 1 and the groove detection platform 2 are pushed toward the prefabricated ground connection wall, so that the splicing flange is inserted into the detection groove 10, and the detection flange 20 is inserted into the splicing groove, and then the flange detection platform 1 and the groove detection platform 2 are continued to be pushed toward the prefabricated ground connection wall, so that the splicing flange and the splicing groove pass through the detection groove 10 and the detection flange 20. If the flange detection is not correct during the movement, If the flange detection platform 1 and the groove detection platform 2 are stuck, it proves that the splicing structure size of the prefabricated ground connection wall is wrong and needs to be corrected. If the flange detection platform 1 and the groove detection platform 2 pass through the entire prefabricated ground connection wall smoothly, it proves that the ground connection wall does not need to be corrected and can be spliced ​​and used. In this way, when the prefabricated ground connection wall is manufactured, simulated splicing can be performed to determine whether the prefabricated ground connection wall can be spliced ​​normally, so that there will be no unsuccessful splicing during construction, and the prefabricated ground connection wall can be prevented from getting stuck during normal construction, thereby improving construction efficiency.

[0029] Although the flange detection platform 1 and the groove detection platform 2 can detect whether the prefabricated ground-connected wall can be spliced, the splicing flange with a width smaller than the detection groove 10 can also pass through the detection groove 10, which results in a gap between the splicing flange and the splicing groove after the prefabricated ground-connected wall is spliced. This gap will affect the stability of the entire prefabricated ground-connected wall structure, resulting in air entering the entire prefabricated ground-connected wall structure after the prefabricated ground-connected wall is installed. In order to solve this technical problem, refer to Figure 2 In this embodiment, the length of the flange detection platform 1 and the groove detection platform 2 is set to be longer than the prefabricated floor connection wall. The upper and lower surfaces of the flange detection platform 1 are provided with a plurality of detection columns 11 for detecting whether the width of the spliced ​​flange is qualified. The detection column 11 is plugged into the flange detection platform 1 and penetrates into the detection groove 10. The plurality of detection columns 11 are arranged along the length direction of the flange detection platform 1. Through the arrangement of the detection columns 11, the detection personnel push the flange detection platform 1 and the groove detection platform 2 to completely block the two sides of the prefabricated floor connection wall, and then the detection personnel go to the flange detection platform 1 and the groove detection platform 2 to completely block the two sides of the prefabricated floor connection wall. The detection column 11 is pushed into the flange detection platform 1. At this time, if the splicing flange of the prefabricated floor connection wall completely conforms to the detection groove 10, the detection column 11 will not be retracted into the flange detection platform 1. If the splicing flange width of the prefabricated floor connection wall is smaller than the detection groove 10, the detection column 11 will be retracted into the flange detection platform 1. In this way, the detection personnel can distinguish whether the splicing flange width of the prefabricated floor connection wall is qualified, and the detection personnel can also determine the specific location of the unqualified position, so that the detection result of the flange detection platform 1 is more accurate.

[0030] Although the setting of the detection column 11 makes the detection result of the flange detection platform 1 more accurate, due to the long length of the prefabricated ground connecting wall, the detection personnel need to push the detection column 11 multiple times, which is very inconvenient. In order to solve this technical problem, in this embodiment, a vertical slide groove 12 is opened on the side of the flange detection platform 1 away from the groove detection platform 2, and an auxiliary device 4 is provided on the flange detection platform 1 for sliding connection with the flange detection platform 1 through the slide groove 12. The auxiliary device 4 includes an upper pressing structure 40 and a lower pressing structure 41. The upper pressing structure 40 includes a slider 42 located in the slide groove 12, a vertical rod 43 arranged at the end of the slider 42 away from the slide groove 12, and a pressure plate 44 located directly above the flange detection platform 1. The vertical rod 43 is perpendicular to the slider 42 and is fixedly connected to the slider 42. The pressure plate 44 is fixedly connected to the vertical rod 43 and has a gap between it and the upper surface of the flange detection platform 1. The pressure plate 44 covers the upper surface of the flange detection platform 1, and the structure of the lower pressure structure 41 is the same as the upper pressure structure 40, but the lower pressure structure 41 is mirrored below the flange detection platform 1 with the upper pressure structure 40 as the base and the center point of the end surface of the flange detection platform 1 as the midpoint. The pressure plate 44 of the upper pressure structure 40 and the pressure plate 44 of the lower pressure structure 41 are fixedly provided with a horizontal locking plate 45 extending outward from the flange detection platform 1 on one side close to the vertical rod 43. The two locking plates 45 are provided with adjusting bolts 46 that pass through the two locking plates 45 and are threadedly connected to the locking plates 45. Through the setting of the auxiliary device 4, when the inspection personnel need to push the inspection column 11, the adjusting bolts 46 are turned to make the pressure plates 44 of the upper pressure structure 40 and the pressure plates 44 of the lower pressure structure 41 push the inspection columns 11 on the upper and lower surfaces of the flange detection platform 1 respectively. In this way, all the inspection columns 11 can be pushed at one time, which is convenient for the inspection personnel to inspect.

[0031] Although the auxiliary device 4 is provided to facilitate detection by the detection personnel, the pressing plate 44 pushes the detection column 11, which will cause one detection column 11 to press against the pressing plate 44, and the pressing plate 44 will not be able to apply pressure to other detection columns 11, resulting in an error in the detection result. In order to solve this technical problem, refer to Figure 3 In this embodiment, a rebound structure 5 having the same number as the detection column 11 is provided between the pressure plate 44 and the flange detection platform 1. The rebound structure 5 includes a rebound plate 50 and a support spring 51. The support spring 51 is located between the pressure plate 44 and the rebound plate 50. One end of the support spring 51 is fixedly connected to the rebound plate 50, and the other end is fixedly connected to the pressure plate 44. The side of the rebound plate 50 away from the support spring 51 faces the detection column 11. When the detection personnel pushes the pressure plate 44, the pressure plate 44 applies pressure to the detection column 11 through the rebound plate 50. After a rebound plate 50 is supported by a detection column 11, it will shrink. When testing other rebound plates 50, because the setting of the support spring 51 can continue to apply pressure to other detection columns 11, thereby completing the detection, so that the pressure plate 44 does not affect the detection structure while facilitating the detection of the detection personnel.

[0032] In order to prevent the flange inspection platform 1 and the groove inspection platform 2 from moving too far when being pushed by the inspectors, in this embodiment, the flange inspection platform 1 and the groove inspection platform 2 are connected to a limit rod 6 at one end on the same side, and an insertion interface is provided at one end of the flange inspection platform 1 and the groove inspection platform 2 connected to the limit rod 6, and plug-in interfaces are provided on both sides of the limit rod 6 with extended plug-in rods 60, which are plugged into the flange inspection platform 1 and the groove inspection platform 2 through the plug-in interfaces. The limit rod 6 can prevent the flange inspection platform 1 and the groove inspection platform 2 from moving too far when being pushed by the inspectors. Through the provision of the plug-in rod 60, the inspectors can adjust the distance between the limit rod 6 and the flange inspection platform 1 and the groove inspection platform 2 according to the length of the prefabricated floor connection wall, so that the limit rod 6 adapts to the length of the prefabricated floor connection wall, thereby improving the practicality and applicability of the limit rod 6.

[0033] Specific implementation process: first, hoist the ground connection wall in a horizontal straight state, then align the splicing flange of the prefabricated ground connection wall with the flange detection platform 1, and the splicing groove with the groove detection platform 2, then push the flange detection platform 1 and the groove detection platform 2 toward the prefabricated ground connection wall, continue to push the flange detection platform 1 and the groove detection platform 2, so that the flange detection platform 1 and the groove detection platform 2 completely block the two sides of the prefabricated ground connection wall, then turn the adjusting bolt 46 to make the pressure plate 44 of the upper pressure structure 40 and the pressure plate 44 of the lower pressure structure 41 push the detection column 11 on the upper and lower surfaces of the flange detection platform 1 respectively, and then observe whether the detection column 11 is retracted into the flange detection platform 1. If so, repair the splicing flange of the prefabricated ground connection wall. Otherwise, push the flange detection platform 1 and the groove detection platform 2 in the opposite direction to make the prefabricated ground connection wall slide out between the flange detection platform 1 and the groove detection platform 2 to complete the detection.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
