Description

Technical Field

[0001] The utility model specifically relates to an arc detection device for the outer wall of high-rise buildings. Background Art

[0002] With the acceleration of the urbanization process, high-rise buildings have become an important part of the modern urban skyline. Their outer walls not only carry the function of aesthetic design, but also are the key barriers to ensure the overall structural safety, waterproof and anti-seepage durability of the building. Therefore, after the construction of high-rise buildings is completed, it is particularly important to conduct a comprehensive and detailed inspection of the outer walls. In the surface condition inspection, visual inspection and hand-held tools (such as magnifying glasses, thickness gauges) are used for assistance, and the areas with problems are recorded and marked. It is necessary to evaluate whether the outer wall surface is flat, crack-free, non-peeling, whether the color is uniform, and other indicators to judge the material quality and construction quality. When detecting whether there is rainwater leakage on the outer wall, it is necessary to use tools such as hygrometers and infrared thermal imagers to detect the wall under rainy seasons or artificial simulated rainfall conditions, and at the same time check the parts prone to water seepage such as window frames and eaves to avoid internal damage caused by long-term leakage. Visually check whether there are corrosion marks on the masonry surface, and when detecting metal components, corresponding tests on the coating thickness and corrosion resistance are required to prevent structural damage caused by corrosion. In the above-mentioned related inspections of the building facade, all require the operation of inspectors. When inspecting the first floor of the building, the inspection process is mature and accurate. However, for the related inspections at high-altitude positions, the inspectors need to hold relevant inspection tools and rely on lifting vehicles or other equipment to lift them. When using a lifting vehicle, the layout and swinging space of the crane have relatively high requirements. For buildings with insufficient layout space for the lifting vehicle or exceeding the maximum rising position of the lifting vehicle, there are difficulties in high-altitude inspections. The inspection of the outer walls of higher floors is relatively difficult, and it is difficult to ensure unified standardization. The inspection of the outer walls after the construction of high-rise buildings is even more difficult. Only the relevant structures on the inner side of the wall can be inspected by entering the room. There are inspection blind spots and non-standardizations in the inspection of the outer walls of higher floors of multi-story buildings and high-rise buildings, which affect the accuracy of building acceptance evaluation. At present, there are no related tools that can avoid outdoor climbing inspections and inspect the outer walls of higher floors of multi-story buildings and high-rise buildings.

Specific embodiments

[0027] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0028] Specific implementation method 1: Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 Describe this embodiment, this embodiment includes a force control rod 1, a return rod 2, a steering sleeve 3, a wall detection piece 4 and a support rod 5, the return rod 2, the steering sleeve 3 and the support rod 5 are arranged in sequence from bottom to top, the return rod 2 is an arc rod, the bottom end of the return rod 2 is provided with a force control rod 1, the top end of the return rod 2 is detachably connected to one end of the support rod 5, the other end of the support rod 5 is hinged with a wall detection piece 4, the inner wall of the wall detection piece 4 is a detection wall that is close to the outer wall 20 of the building, the steering sleeve 3 is arranged between the return rod 2 and the support rod 5, the steering sleeve 3 is sleeved on the return rod 2, the inner wall of the steering sleeve 3 is slidably matched with the outer wall of the return rod 2, one end of the steering sleeve 3 is snap-fitted with the return rod 2, the other end of the steering sleeve 3 is detachably connected to the outer wall of the support rod 5, and the length direction of the support rod 5 is in the same direction as the length direction of the force control rod 1.

[0029] Furthermore, the inner wall of the wall detection piece 4 is provided with a non-slip silicone gasket, which does not affect the exposed position of the relevant detection probe in the wall detection piece 4, ensuring a stable and effective detection process. It can ensure that it is not easy to separate from the wall when detecting high-rise exterior walls, and can be tightly attached to the building exterior wall 20 for a long time. The wall detection piece 4 is connected to the force control rod 1 through the return rod 2, and the return rod 2 is extended outward through the building opening, thereby replacing the arm of the detection personnel, ensuring the safety of the detection personnel during the detection process.

[0030] Furthermore, the wall-stick detection component 4 is an existing detection instrument, and its detection principle is the same as the detection principle of the existing external wall detection instrument. The receiving end of the wall-stick detection component 4 is a detection probe or a camera, and the detection probe or the camera is connected to the return rod 2. The terminal control display screen is in the hands of the detection personnel, and the data obtained by the detection probe or the camera is displayed on the terminal control display screen through existing wireless connection methods such as Bluetooth, which is convenient for the detection personnel to obtain relevant data information.

[0031] Embodiment 2: This embodiment is a further limitation of Embodiment 1. In this embodiment, the return rod 2 is an arc-shaped hollow tube. Another structural form of the return rod 2 is an arc-shaped solid rod, which is specifically selected according to the weight, size and other specific weight requirements of the wall-attached detection member 4. The central angle corresponding to the return rod 2 is 120 degrees to 210 degrees. This angle range can ensure that the return rod 2 is in a state of use with a stable restoring force.

[0032] Furthermore, the bending form of the return rod 2 itself is conducive to completing the protruding posture at the building opening and driving the wall-attached detection member 4 to complete the tightness performance of sticking to the outer wall around the opening. The arc length corresponding to the central angle of 120 degrees to 210 degrees is the optimal value arc length of the return rod 2, ensuring that the tester can stably obtain direct and effective detection data.

[0033] Embodiment 3: This embodiment is a further limitation of Embodiment 1 or 2. In this embodiment, the steering socket 3 is an outer elastic metal sleeve. A bottom ring body 7 is integrally connected to the bottom end of the outer elastic metal sleeve. The bottom ring body 7 is coaxially arranged inside the outer elastic metal sleeve. A first convex rib 8 is arranged on one side of the bottom ring body 7 facing the top end of the return rod 2. A second convex rib 9 is integrally connected to the outer wall of the top end of the return rod 2. An annular card slot 10 is processed on one side of the second convex rib 9 facing the bottom ring body 7. A first connecting sleeve 11 is hinged to the top end of the outer elastic metal sleeve. The inner wall of the first connecting sleeve 11 is processed with a first internal thread. The outer wall of the lower end of the support rod 5 is processed with a first external thread 12 that matches the first connecting sleeve 11. The first connecting sleeve 11 is threadedly connected to the lower end of the support rod 5.

[0034] Furthermore, the first connecting sleeve 11 is hinged to the top end of the outer elastic metal sleeve, that is, when the first connecting sleeve 11 is threadedly connected to the support rod 5, its rotation action does not drive the outer elastic metal sleeve to rotate, ensuring that the outer elastic metal sleeve is in a stable supporting state.

[0035] Furthermore, the structural setting of the steering socket 3 can ensure the stable connection between the return rod 2 and the support rod 5, avoiding phenomena such as unstable connection of the support rod 5. The support rod 5 is detachably connected to the first connecting sleeve 11 by a threaded connection, facilitating the adjustment of the rotation angle of the support rod 5, and at the same time ensuring stable connection and not easy to disassemble after connection, improving the stable supporting performance during the detection process.

[0036] The use process of the steering sleeve 3: adjust the insertion angle of the support rod 5 according to the position of the building outer wall 20 that the wall detection part 4 needs to detect, after inserting the support rod 5 into the return rod 2, rotate the support rod 5 to drive the wall detection part 4 to be attached to the predetermined position of the building outer wall 20, and then move the steering sleeve 3 up from the return rod 2 until the first ridge 8 is inserted into the annular groove 10, and the upper end of the steering sleeve 3 is connected to the outer wall of the support rod 5 that has been rotated, and the connection process with the support rod 5 is realized by screwing the first connecting sleeve 11 itself, thereby limiting the position of the support rod 5 and ensuring that its position is not offset.

[0037] In addition, there is another way to connect the support rod 5 and the return rod 2 in a fixed manner, without the need for a limited connection with the steering sleeve 3. The corresponding detection position of the wall detection component 4 is also a unified fixed position, which can be used for the process of picking up components of fixed length and fixed position in the building exterior wall 20.

[0038] Specific embodiment four: This embodiment is a further limitation of specific embodiments one, two or three. In this embodiment, the force control rod 1 is a three-pronged rod body, and the force control rod 1 includes a first rod body 1-1 and a second rod body 1-2. The length direction of the first rod body 1-1 is the same as the length direction of the support rod 5. One end of the first rod body 1-1 is a first gripping end 13, and the other end of the first rod body 1-1 is fixedly connected to the second rod body 1-2. One end of the second rod body 1-2 is a connecting end that cooperates with the return rod 2, and the other end of the second rod body 1-2 is a second gripping end 6.

[0039] Furthermore, different from the above embodiment, the other end of the first rod body 1-1 is fixedly connected to the middle of the second rod body 1-2. In the three-prong rod body, the inspector uses the first gripping end 13 and the second gripping end 6 to hold the return rod 2 in different postures, thereby inspecting different positions in the building exterior wall 20. In the specific use process, the appropriate hand gripping posture corresponding to different gripping ends can be determined according to different use positions.

[0040] Specific embodiment five: This embodiment is a further limitation of specific embodiments one, two, three or four. In this embodiment, an annular groove 14 is processed on the inner wall of the top end of the return rod 2, and a circle of third ridges 15 is processed on the outer wall of the end of the support rod 5 close to the return rod 2. The third ridge 15 and the annular groove 14 are detachably connected.

[0041] Furthermore, the return rod 2 and the support rod 5 are detachably connected, which facilitates the carrying, disassembly and installation of the utility model.

[0042] Specific implementation method six: This implementation method is a further limitation of specific implementation methods one, two, three, four or five. In this implementation method, the support rod 5 is a straight rod body with a fixed length or a rod body with a variable length.

[0043] Further, the support rod 5 has two structural forms. The first structural form is that the support rod 5 is a straight rod with a fixed length. During the installation process, the length of the support rod 5 remains unchanged and is fixedly installed on the return rod 2. The inspector adjusts the moving positions of the return rod 2 and the support rod 5 by manipulating the force application and position control rod 1, thereby indirectly controlling the wall attachment detection member 4 to detect the exterior wall, and achieving a full range of detection around the hole at a height of 20 of the building exterior wall. The second structural form is a variable-length rod body. During use, the support rod 5 can be telescoped, and the adjusted length of the support rod 5 can be locked. The final adjusted length of the support rod 5 can be correspondingly adjusted according to the height of the position to be detected on the building exterior wall 20.

[0044] Specific Embodiment Seven: This embodiment is a further limitation of Specific Embodiments One, Two, Three, Four, Five, or Six. In this embodiment, when the support rod 5 is a variable-length rod body, the support rod 5 includes an upper sleeve 5-1, a second connecting sleeve 5-2, and a lower rod 5-3. The upper sleeve 5-1, the second connecting sleeve 5-2, and the lower rod 5-3 are arranged in sequence from top to bottom. A second connecting sleeve 5-2 is provided at the bottom end of the upper sleeve 5-1. The upper end of the second connecting sleeve 5-2 is coaxially connected to the bottom end of the upper sleeve 5-1. The inner wall of the lower end of the second connecting sleeve 5-2 is machined with a second internal thread. The upper end of the lower rod 5-3 is inserted into the upper sleeve 5-1. A threaded connection head is provided at the upper end of the lower rod 5-3. The outer wall of the lower end of the lower rod 5-3 is machined with a second external thread. When the support rod 5 is at the shortest length limit position, the lower rod 5-3 is coaxially arranged inside the upper sleeve 5-1, and the second external thread of the lower rod 5-3 is threadedly connected to the second internal thread of the second connecting sleeve 5-2. When the support rod 5 is at the longest length limit position, the lower rod 5-3 is coaxially arranged inside the upper sleeve 5-1, and the threaded connection head of the lower rod 5-3 is threadedly connected to the second internal thread of the second connecting sleeve 5-2.

[0045] Further, the support rod 5 is a single-headed support rod for supporting one wall attachment detection member 4. When the support rod 5 is a variable-length rod body, during the connection process, it is threadedly connected through the cooperation of the internal thread and the external thread, thereby realizing the length change process of the support rod 5. The length can be locked after adjustment, which can prevent the inspector from accidentally lengthening or shortening during use. The stable length can facilitate the detection of different positions on the building exterior wall 20 and continuously cooperate with the wall attachment detection member 4 for detection.

[0046] Embodiment VIII: This embodiment is a further limitation of Embodiment I, II, III, IV, V, VI or VII. In this embodiment, the wall-attached detection member 4 includes a support frame 4-1 and a detection probe 4-2. The support frame 4-1 is a rectangular support frame. An opening 4-3 is provided on the side of the support frame 4-1 facing the building exterior wall 20. The detection probe 4-2 is arranged inside the support frame 4-1, and the detection end of the detection probe 4-2 is located in the opening 4-3. A hinge seat 4-4 connected to the support rod 5 is machined on the other side of the support frame 4-1.

[0047] Furthermore, the detection probe 4-2 is attached to the building exterior wall 20 with an anti-slip silicone frame, which helps the detection probe 4-2 to be firmly attached to the building exterior wall 20, increases the contact friction, and reduces the lifting fatigue of the detector during use. With the cooperation of the hinge seat 4-4, it is convenient to move the detection probe 4-2 and reduces the difficulty of switching the posture of applying the pushing force and the dragging force.

[0048] Embodiment IX: This embodiment is a further limitation of Embodiment I, II, III, IV, V, VI, VII or VIII. The linear distance between the support rod 5 and the force-applying and position-controlling rod 1 is 20-40 cm. As shown in Figure 8 , the support rod 5 is a double-headed support rod, which is used to support two wall-attached detection members 4 at the same time. The two wall-attached detection members 4 are used to detect two adjacent exterior walls in a building. The two wall-attached detection members 4 share one support rod 5. This support rod 5 is a double-fork support rod. The double-fork support rod includes a steering socket 3, a support rod 5 and two wall-attached detection members 4. The two wall-attached detection members 4 are connected to one support rod 5 through two hinge seats 4-4. The steering socket 3 is connected to the support rod 5 and the return rod 2 in a Y-shaped form, ensuring the formation of a double-fork support rod, which is convenient for the detector to detect the adjacent two building exterior walls 20 in the same building at the same time.

The upper end of the support rod 5 is installed on one side of the support frame 4-1 through the hinge seat 4-4. The detection probe 4-2 is installed on the other side of the support frame 4-1. The bottom end of the return rod 2 is fixedly connected to one end of the second rod body 1-2 on the force-applying and position-controlling rod 1. The other end of the second rod body 1-2 is the second holding end 6. The second rod body 1-2 is integrally connected with the first rod body 1-1. One end of the first rod body 1-1 is the first holding end 13.

[0051] Combine Figures 1 to 5 Describe the first working process of the present utility model: After connecting the return rod 2 and the support rod 5, adjust the length of the support rod 5 according to the position to be detected on the building exterior wall 20, so as to adjust the detection position of the wall-attached detection member 4 on the support rod 5, so that it can reach the predetermined position under the support of the return rod 2 and the support rod 5. After the connection is completed, extend the arc detection device from the building opening to ensure that the wall-attached detection member 4 is attached to the exterior wall around the building opening, so as to realize the detection of the peripheral position of the outer wall of the opening. Pull back and control the position of the force application and position control rod 1, so as to ensure that the detection probe 4-2 is tightly attached to the exterior wall to be detected. By holding the first holding end 8 and / or the second holding end 9, the positions of the return rod 2 and the support rod 5 are stabilized, so as to complete the continuous and stable fitting state of the detection probe 4-2. Move the position of the return rod 2 according to the specific detection requirements, so as to drive the detection probe 4-2 to move for detection, or fix the position of the return rod 2, so as to drive the detection probe 4-2 to realize the static detection at a fixed position.

[0052] Combine Figures 1 to 4 、 Figure 6 and Figure 7 Describe the second working process of the present utility model: After connecting the return rod 2 and the support rod 5, adjust the length of the support rod 5 according to the position to be detected on the building exterior wall 20, so as to adjust the detection position of the wall-attached detection member 4 on the support rod 5, so that it can reach the predetermined position under the support of the return rod 2 and the support rod 5. After the connection is completed, extend the arc detection device from the building opening so that the wall-attached detection member 4 is attached to the exterior wall at another position adjacent to the building opening, so as to realize the detection of the exterior wall at the adjacent or diagonally opposite position of the opening. Pull back and control the position of the force application and position control rod 1, so as to ensure that the detection probe 4-2 is tightly attached to the exterior wall to be detected. By holding the first holding end 8 and / or the second holding end 9, the positions of the return rod 2 and the support rod 5 are stabilized, so as to complete the continuous and stable fitting state of the detection probe 4-2.
