Description

Technical Field

[0001] The utility model particularly relates to a device for clamping and sampling the edge of an opening in an exterior wall of a building. Background Art

[0002] Sampling of building exterior walls is a key part of the inspection process. The specific sampling and acceptance process involves taking ten impact points from each of the two levels of testing: the first-floor walls, doors, and windows, which are susceptible to collision (level 10J), and the second-floor and above walls, which are less susceptible to collision (level 3J). For walls constructed using the same materials, processes, and construction methods, each 500-1000 square meter area is divided into one inspection lot. Even areas less than 500 square meters are considered one inspection lot. The division of inspection lots can also be determined by mutual agreement between the construction unit and the construction unit, consistent with the construction process and convenient for inspection and acceptance. According to the inspection batch, adhesive is applied to five representative locations on the surface of each type of base wall, with an area of ​​3~4dm2 and a thickness of 5~8mm. After drying, it is tested according to the provisions of standard JGJ110. The fracture should be cut from the adhesive surface to the base surface. The operation position in the specific sampling process is currently only limited to the first-floor wall and the surrounding positions of the doors and windows on the first floor. The operator can operate at the ground position, but there is a lack of relevant sampling data on high-rise buildings or high-rise floors in multi-story buildings. The acquisition process is cumbersome due to the need to contact large-scale lifting equipment, and the operation process is difficult to unify and standardize. Due to insufficient external suspension power, the sampling process can only rely on outdoor suspension by inspection personnel or with the help of large-scale lifting equipment. There are many defects and difficulties. There is no solution to the problem of simple, stable and standardized sampling at high-rise floors in high-rise buildings or multi-story buildings.

[0026] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0027] Specific implementation method 1: Combination Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 Explanation of this embodiment, this embodiment includes a main support rod 1, a tightening member 2, an electric control sampler 3 and a first gripping handle 4, the main support rod 1 is a U-shaped rod body, the main support rod 1 includes a main telescopic member 5, a first support rod 6 and a second support rod 7, the main telescopic member 5 is arranged horizontally, the first support rod 6 and the second support rod 7 are respectively arranged vertically and side by side at the two ends of the main telescopic member 5, the first gripping handle 4 is arranged on the main support rod 1, the first gripping handle 4 is arranged close to the first support rod 6, and one end of the first support rod 6 is arranged on the main telescopic member One end of the retractable part 5 and the other end of the first support rod 6 are provided with a tightening part 2, one end of the second support rod 7 is detachably connected to the other end of the main retractable part 5, and the other end of the second support rod 7 is provided with an electric-controlled sampler 3. The tightening part 2 and the electric-controlled sampler 3 are coaxially arranged relative to each other, and a variable amplitude clamping part 8 is formed between the tightening part 2 and the electric-controlled sampler 3 to cooperate with the building exterior wall 20. When the hole edge clamping sampling device is in the sampling state, the tightening part 2 is pressed against the inner side 21 of the exterior wall, and the sampling end of the electric-controlled sampler 3 is pressed against the outer side 22 of the exterior wall.

[0028] Furthermore, the first gripping handle 4 is arranged in the same direction as the length direction of the first support rod 6. During single-person use, the inspector can avoid extending his body or hands outside the hole when taking samples on high-rise exterior walls or multi-story buildings, avoiding the process of inspectors performing suspended sampling and testing at high altitudes, thereby improving the safety of inspectors during testing operations. A tightening member 2 is provided on the first support rod 6, and the screwing end is rotated to cooperate with the screw 2-1 so that the bonding piece 2-2 is attached to the inner side 21 of the exterior wall, and the sampling end of the electric-controlled sampler 3 is tightly attached to the outer side 22 of the exterior wall, thereby realizing the blind operation process of the electric-controlled sampler 3.

[0029] Furthermore, the utility model is only used for shallow surface sampling of the building exterior wall 20, and the sampling depth is 3 to 7 centimeters. During the sampling process, the main telescopic part 5 drives the second support rod 7 and the electric control sampler 3 to move toward the indoor direction, ensuring that the electric control sampler 3 is inserted into the wall to a certain depth according to the detection requirements when driven, thereby performing shallow sampling of the outer layer of the building exterior wall 20.

[0030] Specific embodiment 2: This embodiment is a further limitation of specific embodiment 1. In this embodiment, the main telescopic member 5 is a telescopic cylinder or a telescopic hydraulic cylinder, and its working principle is the same as that of existing telescopic cylinders or telescopic hydraulic cylinders. The main telescopic member 5 includes a rear seat 5-1, an outer cylinder 5-2, an inner piston rod 5-3, and a front seat 5-4. The rear seat 5-1 is fixedly connected to one end of the outer cylinder 5-2. The rear seat 5-1 is machined with a first mounting hole 5-5 that matches the first support rod 6. The other end of the outer cylinder 5-2 is equipped with an inner piston rod 5-3. One end of the inner piston rod 5-3 is inserted into the outer cylinder 5-2. The other end of the inner piston rod 5-3 is integrally connected to the front seat 5-4. The front seat 5-4 is machined with a second mounting hole 5-6 that matches the second support rod 7.

[0031] Furthermore, during the sampling operation of the electric sampler 3, the main telescopic member 5 can make a corresponding coordinated recovery action as the sampling depth of the electric sampler 3 gradually deepens, that is, the inner piston rod 5-3 gradually retracts into the outer cylinder 5-2, and the corresponding control is performed through the existing electric control program. The main telescopic member 5 can make corresponding actions by operating the relevant electric control handle on site by the inspection personnel. The extension and retraction actions of the main telescopic member 5 can be specifically debugged according to the on-site inspection conditions.

[0032] Furthermore, during the sampling process, the piston rod 5-3 in the outer cylinder 5-2 is extended outward by the action of air pressure, and the inspection personnel put the building outer wall 20 between the pressing part 2 and the electric control sampler 3, and press the electric control sampler 3 against the building outer wall 20, and tighten the pressing part 2 to fix the building outer wall 20. After fixation, the piston rod 5-3 in the outer cylinder 5-2 is contracted inward by the action of air pressure, thereby driving the second support rod 7 and the electric control sampler 3 to move toward the indoor direction, so that the sampling tube 3-1 on the electric control sampler 3 is inserted into the wall to perform sampling of the outer shallow layer, and the sampling thickness is 3 to 7 centimeters.

[0033] Specific embodiment three: This embodiment is a further limitation of specific embodiment one or two. In this embodiment, the length direction of the first gripping handle 4 is in the same direction as the length direction of the first support rod 6. The first support rod 6 passes through the first mounting hole 5-5 and is fixedly connected to one end of the first gripping handle 4. The other end of the first gripping handle 4 is the first gripping end 4-1.

[0034] Furthermore, during single-person operation, the electric sampler 3 is placed on the outside of the outer wall 22, and the tightening member 2 is placed on the inside of the outer wall 21, so that when the inspector holds the first gripping end 4-1, he can achieve stable positioning on the inner wall of the building's outer wall 20 by screwing the tightening member 2 indoors.

[0035] Specific embodiment four: This embodiment is a further limitation of specific embodiment two. In this embodiment, the length direction of the first gripping handle 4 is in the same direction as the length direction of the main telescopic part 5. One end of the first gripping handle 4 is fixedly connected to the rear seat body 5-1, and the other end of the first gripping handle 4 is the first gripping end 4-1.

[0036] Furthermore, the cooperation between the first gripping handle 4 and the second gripping handle 9 can realize the exterior wall sampling work of high-rise exterior walls or multi-story high-rise buildings by two people. One of the inspectors holds the first gripping handle 4 and the second gripping handle 9 with both hands at the same time to achieve the stability of the position of the outer side 22 of the exterior wall and the inner side 21 of the exterior wall. When the length direction of the first gripping handle 4 is in the same direction as the length direction of the main telescopic part 5, it is convenient for the inspector to apply force more easily when holding the first gripping handle 4, thereby improving the stability of the main support rod 1, and the inspector can choose a suitable gripping posture according to the height position of the hole during specific maintenance.

[0037] Specific embodiment five: This embodiment is a further limitation of specific embodiments two, three or four. In this embodiment, the second support rod 7 includes a connecting rod 7-1 and a connecting nut 7-2. One end of the connecting rod 7-1 passes through the second mounting hole 5-6 and is connected to the connecting nut 7-2. The other end of the connecting rod 7-1 is provided with the electronically controlled sampler 3.

[0038] Furthermore, the connecting nut 7-2 is used to fix the second support rod 7 to avoid loosening during the detection process. The other end of the second gripping handle 9 is connected to the connecting nut 7-2, which can ensure the operation process of two people.

[0039] Specific embodiment six: This embodiment is a further limitation of specific embodiment five. In this embodiment, a second gripping handle 9 is provided on the front seat body 5-4 or the connecting nut 7-2. One end of the second gripping handle 9 is fixedly connected to the front seat body 5-4 or the connecting nut 7-2, and the other end of the second gripping handle 9 is a second gripping end 9-1.

[0040] Furthermore, during the inspection process, two people can carry out exterior wall sampling work. One person maintains the stability of the main support rod 1 by holding and applying force, which is conducive to improving the sampling quality of the electric control sampler 3. The other person observes and adjusts the top tightening member 2 in time as needed, which is conducive to maintaining the positioning connection strength of the inner side of the building exterior wall 20. With the help of one end with the electric control sampler 3 extending from the building opening, the artificial high-altitude suspended sampling inspection process is avoided. One of the inspectors holds the first holding handle 4 and the second holding handle 9 with both hands at the same time to achieve the stability of the position of the outer side 22 and the inner side 21 of the exterior wall. The other inspector can adjust the moving distance of the top tightening member 2 according to the sampling depth. At the same time, during the inspection process, the inspectors can find a suitable hand-holding posture to improve efficiency.

[0041] Specific embodiment seven: This embodiment is a further limitation of specific embodiment one or four. In this embodiment, the electronically controlled sampler 3 includes a sampling barrel 3-1, a supporting disc frame 3-2, a turntable 3-3 and a drive motor 3-4. The turntable 3-3 is arranged in the supporting disc frame 3-2, the second support rod 7 is connected to the supporting disc frame 3-2, the power output end of the drive motor 3-4 passes through the supporting disc frame 3-2 and is connected to one side of the turntable 3-3, and a sampling barrel 3-1 is arranged on the other side of the turntable 3-3. One end of the sampling barrel 3-1 is connected to the turntable 3-3, and the other end of the sampling barrel 3-1 is a rotating screw-in end. The inner cavity of the sampling barrel 3-1 is a sample holding cavity 3-5.

[0042] Furthermore, during the sampling process, it can be ensured that the piston rod 5-3 in the outer cylinder 5-2 is driven by the air pressure to drive the second support rod 7 to retract inward, thereby driving the sample holding chamber 3-5 of the sampling tube 3-1 to retract inward, and the power output end of the driving motor 3-4 drives the sampling tube 3-1 to be inserted into the wall for sampling.

[0043] Specific embodiment eight: This embodiment is a further limitation of specific embodiments one, two, three, four, five, six or seven. In this embodiment, the tightening member 2 includes a screw 2-1 and a bonding sheet 2-2. A threaded hole that matches the screw 2-1 is processed on the first support rod 6. One end of the screw 2-1 passes through the threaded hole and is connected to the bonding sheet 2-2. The bonding sheet 2-2 is tightly attached to the inner side 21 of the outer wall, and the other end of the screw 2-1 is a screwing end.

[0044] Furthermore, during the sampling process of the exterior wall, the electric-controlled sampler 3 is attached to the designated position for detection on the outside 22 of the exterior wall. The screw 2-1 on the tightening member 2 cooperates with the first support member 6 to enable the inspector to rotate the screwing end to fit the screw 2-1 and the fitting piece 2-2 toward the inside 21 of the exterior wall, thereby avoiding the inspector from hanging outdoors for sampling, and ensuring a stable fitting state to the wall. The entire inspection process does not require manual probing outside the hole for sampling. The position of the electric-controlled sampler 3 on the outside of the building exterior wall 20 can be known by observing the position of the tightening member 2.

[0045] Specific implementation method 9: This implementation method is a further limitation of specific implementation methods 1, 2 or 3. Figure 8 As shown, a structural form of the support disc frame 3-2 is that it includes a general clamping frame and bearings. The general clamping frame is horizontally arranged, and the general clamping frame is an L-shaped frame. The driving motor 3-4 is fixedly connected to the outer side of the vertical section of the general clamping frame, and the general clamping frame provides support for it. A turntable 3-3 is vertically arranged at the half-slot position formed between the horizontal section and the vertical section of the general clamping frame. A bearing is passed through the vertical section of the general clamping frame. The power output end of the driving motor 3-4 is connected to one side of the turntable 3-3 through the bearing, and the sampling barrel 3-1 is provided on the other side of the turntable 3-3. The horizontal section in the general clamping frame is connected to the second support rod 7, and the general clamping frame provides support for the driving motor 3-4, the turntable 3-3 and the sampling barrel 3-1.

[0046] The cam 3-3 is connected to the drive shaft 3-4 of the vehicle 3-5 and the two drive shafts 3-6 are connected, and the cam 3-3 is connected to the drive shaft 3-4 of the vehicle 3-5.

[0047] Furthermore, the rotating screw-in end of the sampling tube 3-1 is processed with a circumferential blade to facilitate cutting and sampling.

[0049] Install the tightening member 2 on the first support rod 6 and the second support rod 7 on the front seat body 5-4. The inspector will enclose the main support rod 1 with the tightening member 2 and the electric sampler 3 at the building outer wall 20 around the hole, ensuring that the rotating screw-in end of the sampling tube 3-1 in the electric sampler 3 is tightly attached to the outer side 22 of the outer wall. The inspector holds the first gripping end 4-1 on the first gripping handle 4 with one hand, and tightens the screwing end on the tightening member 2 with the other hand to ensure that the screw 2-1 drives the bonding piece 2-2 to be tightly attached to the inner side 21 of the outer wall.

[0050] Combine Figure 6 and Figure 7 The working process of realizing single-person operation is as follows: the inspector performs sampling work on the building exterior wall 20 at a high-rise exterior wall or a multi-story building exterior wall. First, the main support rod 1 with the top tightening piece 2 and the electric control sampler 3 is enclosed at the building exterior wall 20 around the hole, so that the building exterior wall 20 is in the variable amplitude clamping part 8, and the end of the second support rod 7 with the electric control sampler 3 is on the outside 22 of the exterior wall.

The inspector holds the first gripping end 4-1 with one hand to ensure that the main support rod 1 is stably clamped on the building exterior wall 20, and the inspector uses the screw end on the top tightening piece 2 with the other hand to make the screw 2-1 drives the bonding sheet 2-2 to stick tightly to the inner side 21 of the outer wall, starts the electric-controlled sampler 3, and the electric-controlled sampler 3 cuts and samples the outer wall 20 of the building. Synchronously, the piston rod 5-3 in the main telescopic part 5 moves toward the indoor direction, driving the second support rod 7 and the electric-controlled sampler 3 to move toward the indoor direction, ensuring that the utility model is continuously in a dynamic sampling process in a clamping stable state. After the electric-controlled sampler 3 completes sampling, the drive motor 3-4 reverses and drives the sampling tube 3-1 to rotate out of the outer wall 20 of the building. Synchronously, the piston rod 5-3 in the main telescopic part 5 moves toward the outdoor direction. Finally, the top tightening part 2 is loosened to remove the utility model from the outer wall 20 of the building.
