Description

Technical Field

[0001] The present invention belongs to the technical field of building engineering, and more specifically, relates to a multifunctional transport device and method for building dampers. Background Art

[0002] With the advancement of urbanization, the number of high-rise buildings continues to increase. When these buildings face natural disasters such as earthquakes and wind, effective earthquake and wind resistance measures need to be taken to ensure their stability and safety. Dampers, as a device that converts the vibration energy of a building into heat energy or other forms, can effectively reduce the shaking of the building and improve the overall stiffness and stability of the structure.

[0003] In the prior art, in order to minimize the encroachment on the internal usable space of the building, the damper is usually set at the position of the walls around the building. The order of installation is usually to install the upper floor beam first, followed by the upper cantilever wall, then embed the damper, and then install the lower cantilever wall, and finally complete the laying of the lower floor beam, that is, "upper floor beam-upper cantilever wall-damper-lower cantilever wall-lower floor beam". However, the following problems are usually encountered during the installation, use and maintenance process: 1. There is a construction interval between the upper and lower cantilever walls of the damper, and they are not formed at the same time, which easily causes the upper and lower cantilever walls to deviate in the horizontal and vertical directions of the space, and the damper installation requires precision. 1. The upper and lower cantilever walls are too high, and it is difficult to adjust them after the construction is completed, which has an adverse effect on the installation; 2. The damper installation position is close to the infill wall, and the upper and lower cantilever walls are too close to the infill wall, resulting in the inability to weld the side of the support close to the infill wall to the embedded parts during the installation of the damper. The welding cannot ensure the construction quality, and when the damper needs to be replaced later, it will be unfavorable for construction due to the narrow space; 3. When the damper installation position is on the beam of the overhead layer, there is no floor slab around it, and it is not easy to move the damper to the installation position during construction; 4. When the damper is located on the exterior wall of the building, it is exposed to the sun and rain for a long time, and the outside rainwater can easily penetrate into the support position of the damper, causing erosion to the support and damaging the seismic effect of the damper. Summary of the invention

[0004] According to a first aspect of the present invention, there is provided a multifunctional transport device for a building damper, comprising a fixing unit, a transport unit and an auxiliary unit, wherein:

[0005] The fixing unit includes an upper cantilever wall, a lower cantilever wall arranged at the lower side of the upper cantilever wall, a damper arranged between the upper cantilever wall and the lower cantilever wall, and connecting steel pins connecting the damper to the upper cantilever wall and the lower cantilever wall respectively;

[0006] The transport unit includes a moving component, a supporting component arranged on the moving component, a traction component for realizing damper transport, and a lifting component for controlling the lifting and lowering of the transport device; the traction component includes a platform plate arranged on the supporting component, axillary plates arranged on both sides of the platform plate, a hinge, and a folding plate connected to the hinge at one end; the lifting component includes a lifting plate, an adjusting member for inserting a gear hole to adjust the lifting plate, a movable rod with one end arranged on a nut and the other end arranged on the lifting plate, and a connecting rod arranged in the horizontal direction of the screw; the damper is transported by the overall cooperation of the lifting component with the front transport damper and the traction component.

[0007] Furthermore, the traction component includes a winch and a roller arranged on the platform plate, a steel wire rope connecting the winch and the roller, a roller, and a locking hole for inserting a locking rod.

[0008] Furthermore, the lifting component includes a gear hole, a locking rod, a screw rod, and nuts disposed at both ends of the screw rod.

[0009] Furthermore, the adjusting component includes a crank for realizing rapid adjustment of the lifting plate and a knob for realizing fine adjustment of the lifting plate.

[0010] Further, the upper cantilever wall includes an upper cantilever wall reinforcement laid inside, an upper support embedded part arranged at the lower left corner of the upper cantilever wall, and an upper support arranged on the upper support embedded part;

[0011] The lower cantilever wall comprises lower cantilever wall reinforcement bars laid inside, a lower support embedded part arranged at the upper right corner of the lower cantilever wall, and a lower support arranged on the lower support embedded part.

[0012] Furthermore, the haunch plates are vertically installed at the midpoints of the long sides at the left and right ends of the platform plate;

[0013] The folding plate is an extension of the front end of the platform plate of the handling device, one end of which is connected to the front end of the platform plate and the other end of which is against the ground;

[0014] The hinges are arranged at the front end of the platform plate and the rear end of the folding plate, and the intersection edges of the two plates are used as axes for rotation, so as to facilitate the recovery of the folding plate to the platform plate.

[0015] Furthermore, the lifting plate is arranged at the upper part of the front end of the platform plate, horizontally overlapping with the platform plate, and its surface is provided with a plurality of evenly arranged rollers and locking holes, and the lower surface is connected to the movable rod.

[0016] Furthermore, the movable rod is arranged in the vertical direction of the screw rod, and moves in the vertical direction as the nut rotates;

[0017] The connecting rod is arranged in the horizontal direction of the screw rod and moves in the horizontal direction as the nut rotates.

[0018] Furthermore, the auxiliary unit also includes a canopy including a baffle arranged on the outer wall of the damper.

[0019] According to a second aspect of the present invention, there is provided a method for transporting a multifunctional transport device for a building damper, the steps comprising:

[0020] S100: Forming of lower cantilever wall: First, locate the lower floor beam, then use a high-precision total station to determine the position of the lower cantilever wall and its lower floor beam, and insert positioning steel bars at the intersection of the lower cantilever wall edge lines. Based on this, install the prefabricated lower cantilever wall steel bars on the lower floor beam, and then locate the upper floor beam and the upper cantilever wall in turn. According to the measured lower cantilever wall position, install the prefabricated lower cantilever wall steel bars on the lower floor beam, ensuring that the relative position relationship between the upper cantilever wall and the lower cantilever wall is accurate, thereby ensuring the installation accuracy of the damper.

[0021] S200: Forming of upper cantilever wall: After completing the installation of the lower cantilever wall reinforcement and pouring the lower floor slab, tie the upper floor slab reinforcement according to the design drawing, accurately locate the main beam and formwork position of the upper cantilever wall, install the upper cantilever wall reinforcement, embedded parts and protective layer pads, and then pour concrete; after the settlement is stable, remove the formwork and clean the embedded parts; finally, after the upper floor slab support frame is removed, install the lower cantilever wall support embedded parts, clean and pour concrete, and complete all cleaning work.

[0022] S300: Treatment of reserved openings in the infill wall: To facilitate welding during damper installation and later damper replacement, half-thick masonry is used for construction of the infill wall near the cantilever wall and the damper installation area. To ensure the safety and stability of the opening, a lintel is set above the reserved opening, providing ample working space.

[0023] S400: Damper installation: In the order of "lower support - damper - upper support", each component is positioned on the embedded parts of the lower cantilever wall and the upper cantilever wall in turn through the handling and installation device and the winch. During this period, the height is fine-tuned and fixed by using the lifting plate, crank handle and knob. The locking rod is used to prevent the damper from rolling. Finally, the connection and installation of all components are completed by connecting steel pins.

[0024] S500: When the damper needs to be replaced, open the baffle, move the damper handling and installation device to the cantilever wall below the damper, place the front end of the device close to the cantilever wall, shake the handle to lift the lifting plate at the front end of the device to the upper surface of the cantilever wall, remove the steel pins connecting the damper to the upper and lower supports, drag the damper onto the lifting plate, lower the lifting plate, unload the replaced damper to the ground, replace it with a new damper, and complete the replacement according to the installation steps.

[0025] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0026] 1. A multifunctional transport device for building dampers of the present invention, by arranging a winch as a traction device, gives the device a strong traction force, and by a precise mechanical transmission system, realizes accurate control and smooth movement of heavy objects, subverts the mode of relying on a large amount of manpower in traditional transport operations, and at the same time, by arranging a folding plate with highly flexible rollers and a lifting plate with adjustable height, the folding plate takes into account the needs of space utilization and portability, and the rollers arranged thereon ensure smooth sliding during the transport process, while the lifting plate can adjust the height according to actual needs through a precise mechanical adjustment mechanism, so that the optimal operating position can be achieved whether the damper is loaded or unloaded, further reducing the physical burden of the operator, and the device can be completed by a single person, which not only greatly improves the transport efficiency, but also significantly reduces the labor cost, and is particularly suitable for large-scale, high-intensity installation projects.

[0027] 2. The multifunctional handling device for building dampers of the present invention passes the steel wire rope around the roller, optimizes the stress state of the steel wire rope during operation, effectively reduces the physical loss caused by direct contact and friction, and significantly improves the wear of the steel wire rope through the smooth guidance of the roller, thereby greatly extending its service life, reducing maintenance costs and replacement frequency, and improving the economy and efficiency of the overall operation. The roller is thin in the middle and thick at both ends, so that the steel wire rope can fit closely to the roller surface during traction, limiting its unnecessary range of motion on the roller, and effectively avoiding safety hazards caused by excessive left and right sliding.

[0028] 3. A multifunctional carrying device for building dampers of the present invention flexibly connects the folding plate and the lifting plate through a hinge. When the device is assembled or in a non-working state, the folding plate can be placed and fit on the upper surface of the lifting plate, which greatly reduces the active space occupied by the entire device and makes storage and transportation more convenient and efficient. When the device enters the use state, the operator can easily use the rotation mechanism of the hinge to smoothly unfold and rotate the folding plate from the lifting plate to a position in contact with the ground. This step not only simplifies the cumbersome process of traditional installation process that requires manual labor to lift the folding plate to align with the installation position, but also directly realizes the folding plate and the ground or the target installation object, which greatly reduces the labor intensity of the staff and improves work efficiency. It also reduces the safety risks that may be caused by improper manual operation, and avoids the accumulation of errors caused by too many intermediate links.

[0029] 4. The method of the present invention adopts a special masonry method in the area of ​​the filling wall adjacent to the installation position of the damper, that is, the width of the filling wall in the area is halved for masonry, and on this basis, a lintel structure is cleverly added, which not only ensures that the damper can have sufficient operating space during the installation and replacement construction process that may be needed in the future, thereby greatly facilitating the construction operation and improving the work efficiency; at the same time, by adding the lintel structure, the structural integrity and stability of the filling wall are effectively enhanced, and the adverse effects on the overall structural safety caused by local changes are avoided. The masonry method of halving the width reduces the volume of the wall directly next to the installation position of the damper, providing a more spacious working environment for the construction personnel, so that the installation, commissioning and even future maintenance and replacement of the damper can be carried out more smoothly and unimpeded. The setting of the lintel, which spans the half-width wall, not only firmly connects the walls on both sides together, but also shares and transmits the load of the wall through its own structural strength, ensuring that even if the width of the wall is adjusted locally, the entire filling wall can still maintain good structural integrity and bearing capacity.

[0030] 5. The method of the present invention fundamentally avoids potential accumulation of construction errors by first casting the upper cantilever wall, then casting the lower cantilever wall, and finally installing the damper in the construction sequence, ensuring that the damper can be accurately and stably installed in the predetermined vertical direction. The construction sequence adopted by the present invention effectively avoids this risk. Casting the upper cantilever wall first means that its position and shape can be used as a reference in the subsequent construction process, ensuring that the subsequently cast lower cantilever wall can be accurately aligned with it in the vertical direction. Even if a slight deviation is found from the upper cantilever wall during the casting of the lower cantilever wall, there is still a large room for adjustment. The construction personnel can adjust the position of the lower cantilever wall by bending the steel bars of the lower cantilever wall, expanding the embedded bars, and other flexible operating methods to make it perfectly aligned with the upper cantilever wall, ensuring that the damper can be accurately positioned in the predetermined vertical direction during installation.

[0047] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0049] In this patent, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "includes..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0050] Depend on Figure 1-10 It can be seen that the embodiment of the present invention provides a multifunctional transport device for building dampers, including a fixing unit 1, a transport unit 2 and an auxiliary unit 3; the transport unit 2 is used to transport the damper on the fixing unit 1 after installation and removal, and the auxiliary unit 3 is used to enhance the performance of the fixing unit and the protection of the damper. The transport unit 2 is provided with a winch as a traction device, which gives the device a strong traction force, and also realizes precise control and smooth movement of heavy objects through a precise mechanical transmission system, subverting the mode of relying on a large amount of manpower in traditional transport operations. At the same time, by providing a folding plate with highly flexible rollers and a lifting plate with adjustable height, the folding plate takes into account the needs of space utilization and portability, and the rollers provided thereon ensure smooth sliding during the transport process, while the lifting plate can adjust the height according to actual needs through a precise mechanical adjustment mechanism. Whether loading or unloading the damper, the optimal operating position can be achieved, further reducing the physical burden of the operator. The device can be completed by a single person, which not only greatly improves the transport efficiency, but also significantly reduces the labor cost, and is particularly suitable for large-scale, high-intensity installation projects.

[0051] Depend on Figure 6-8 It can be seen that the fixing unit 1 includes an upper cantilever wall 11, a lower cantilever wall 12 arranged at the lower side of the upper cantilever wall 11, a damper 14 arranged between the upper cantilever wall 11 and the lower cantilever wall 12, and a connecting steel pin 13 connecting the damper 14 to the upper cantilever wall 11 and the lower cantilever wall 12 respectively.

[0052] The upper cantilever wall 11 includes an upper cantilever wall reinforcement 113 laid inside, an upper support embedded part 111 arranged at the lower left corner of the upper cantilever wall 11 , and an upper support 112 arranged on the upper support embedded part 111 .

[0053] The lower cantilever wall 12 includes a lower cantilever wall reinforcement 123 laid inside, a lower support embedded part 121 disposed at the upper right corner of the lower cantilever wall 12 , and a lower support 122 disposed on the lower support embedded part 121 .

[0054] The upper cantilever wall 11, as a key component in the building structure, adopts a sturdy and durable reinforced concrete structure design. During its construction process, the upper cantilever steel bars and upper support embedded parts are first carefully installed to ensure accurate positioning, stability and reliability. Subsequently, high-quality concrete is poured to tightly combine these components to form a whole, thereby playing the role of a bridge connecting the damper and the upper floor slab, effectively transmitting and dispersing force, and enhancing the stability and seismic resistance of the building.

[0055] The upper cantilever wall reinforcement 113 is made of frame main reinforcement, stirrups and tie bars, which not only strengthens the structural strength of the wall, but also ensures the tight connection between the reinforcements. The upper part is carefully embedded in the reinforcement of the beam of the upper floor slab, achieving seamless connection and force transmission between floors, further improving the overall stability of the building.

[0056] The upper support embedded part 111 is usually composed of multiple threaded steel bars with a diameter of not less than 20 mm as legs, which are symmetrically welded to a rectangular steel plate with a thickness of not less than 20 mm to form a stable and strong support structure. The embedded part legs are firmly embedded in the upper cantilever wall steel bars to ensure the reliability of its fixation; while the steel plate is closely connected to the upper support, and its width is just equal to or slightly less than the width of the cantilever wall, which not only ensures the tightness of the connection, but also avoids unnecessary waste of space.

[0057] The upper support 112 is a metal component, which is composed of two quarter-circular steel web straight edges precisely welded along the opposite edges of a steel rectangular bottom plate. A circular connecting steel pin hole is reserved on each web to facilitate flexible and stable connection with one end of the damper. The bottom plate of the upper support is tightly connected with the steel plate of the upper support embedded part, ensuring the continuity and stability of force transmission; and the web is tightly connected with the damper, together forming an important part of the building shock absorption and isolation system.

[0058] The lower cantilever wall 12 has the same structure as the upper cantilever wall 11 and will not be described in detail here.

[0059] The lower cantilever wall reinforcement 123 has the same structure as the upper cantilever wall reinforcement, which will not be described in detail here.

[0060] The structure of the lower support embedded part 121 is the same as that of the upper support embedded part 111 , the embedded part legs are embedded in the lower cantilever wall steel bars 123 and fixed, and the steel plate is connected to the lower support 122 .

[0061] The structure of the lower support 122 is the same as that of the upper support 112 , the bottom plate of the lower support is connected to the steel plate of the lower support embedded part 121 , and the web is connected to the other end of the damper 14 .

[0062] The connecting steel pin 13 adopts a metal component design with a columnar structure, which can not only firmly connect the damper and the upper and lower supports, but also maintain a stable shape when subjected to force, thereby ensuring the stability and safety of the entire structure.

[0063] The damper 14 is a shock absorbing device widely used in various buildings to effectively absorb and dissipate structural vibration energy caused by wind, earthquake, moving load and power equipment. According to different materials, structures and working principles, dampers can be divided into various types, such as viscoelastic dampers, viscous dampers, metal yield dampers, etc. The design of the device of the present invention is highly versatile and adaptable, and can be applied to any type of damper.

[0064] Depend on Figure 1-4 It can be seen that the transport unit 2 includes a moving component 21, a supporting component 22 arranged on the moving component 21, a traction component 23 for transporting the damper, and a lifting component 24 for controlling the lifting of the transport device.

[0065] Depend on Figure 1 It can be seen that the moving part 21 includes a plurality of universal wheels 211. The universal wheels 211 can not only support the device to move freely in any direction in a plane, whether it is forward, backward or lateral translation, it can be easily achieved, thereby greatly improving the working efficiency and flexibility, but more importantly, these universal wheels are equipped with a reliable locking mechanism, allowing the operator to quickly fix the position of the device when necessary to ensure stability during the construction process. This instant and controllable positioning capability makes the entire handling and installation process more accurate and efficient, and reduces errors or safety hazards that may be caused by improper position adjustment.

[0066] Depend on Figure 1It can be seen that the support member 22 includes a leg 221. The leg 221 supports the handling device, and is connected to the platform plate 231 at the upper part and to the universal wheel 211 at the lower part. In order to prevent the platform plate 231 from sinking and deforming due to the damper load, in addition to setting a leg at each end corner of the platform plate 231 to provide basic four-point support, an additional leg 221 is also added at the midpoint of the long side of the platform plate 231. This not only effectively disperses the load borne by the platform plate 231, significantly improves its load-bearing capacity and anti-deformation ability, but also enables the entire handling device to maintain a high degree of stability and safety when facing uneven load distribution or extreme load conditions.

[0067] Depend on Figure 1-2 It can be seen that the traction component 23 includes a platform plate 231 arranged on the support leg 221, a winch 232 arranged on the platform plate 231, a side plate 233 arranged on both sides of the platform plate 231, a roller 235, and a wire rope 234 connecting the winch 232 and the roller 235, a roller 237, a locking hole 236 for inserting a locking rod, a hinge 239 and a folding plate 238 connected to the hinge 239 at one end.

[0068] The platform plate 231 is the bearing part of the handling device. A winch 232 is installed on the platform plate 231 as a traction part. Through its strong pulling force, the items can be easily handled. A lifting plate 243 and a folding plate 238 are installed at one end of the platform plate 231 as the lifting part. The lifting plate 243 can adjust the height according to actual needs to meet the loading requirements of different goods; and the folding plate 238 can be folded up when not in use to reduce space occupation, and can be quickly unfolded when needed to provide additional support for overlong or special-shaped goods, thereby enhancing the versatility and adaptability of the handling device. The lower part of the platform plate 231 is connected to six legs 221. These legs 221 not only provide a stable support foundation for the platform, but also can be appropriately adjusted according to the terrain conditions of the work site to ensure that the handling device can maintain horizontal stability in any environment, thereby ensuring the safe and smooth progress of the operation.

[0069] It can be known that the winch 232 is a power device used for traction of the transport device, which is fixed to the platform plate 231 by bolts to provide traction to pull the damper to move.

[0070] The steel wire rope 234 is a towing member on the winch, with the end connected to the winch, and the front end passing through the roller to connect to the damper, and transmits the traction force of the winch to the damper, and drags the damper to the front end position of the platform plate;

[0071] The axle plates 233 are vertically installed at the midpoints of the long sides of the left and right ends of the platform plate 231, and are reinforced close to the two side edges of the platform plate to form a stable supporting structure, thereby enhancing the structural strength of the platform plate 231 when subjected to stress. The main function of the axle plates is that when the winch starts to pull the damper to work, they can effectively disperse and withstand the various forces and vibrations generated thereby, thereby significantly improving the stability and safety of the entire system and ensuring that the damper can smoothly and accurately complete its predetermined actions.

[0072] A roller 235 is arranged between the axil plates 233 at the left and right ends of the platform plate 231. The roller 235 is arranged between the axil plates at the left and right ends of the platform plate. The two ends of the roller are large-diameter metal columnar structures, which are fixed to the axil plates. The middle part of the roller is a small-diameter metal columnar structure, which can generate relative rotation with the two ends of the roller to facilitate the rolling of the wire rope when it is passed through.

[0073] The locking holes 236 are evenly distributed on the entire surface of the lifting plate, that is, holes are opened on the lifting plate 243 to facilitate the insertion of the locking rod, so that the position of the damper can be fixed when needed.

[0074] The rollers 237 are arranged on the lifting plate and the folding plate 238. When the damper is pulled, the bottom part contacts the rollers, and the friction movement is changed into relative rolling, thereby effectively improving the pulling effect.

[0075] The folding plate 238 is an extension of the front end of the platform plate of the transport and installation device. One end is connected to the front end of the platform plate and the other end is against the ground, which is convenient for transporting the damper to the platform plate. After transporting, it can be folded onto the platform plate to reduce space.

[0076] The hinge 239 is arranged at the front end of the platform plate 231 and the rear end of the folding plate 238 to connect the two plates. The hinge 239 can be rotated with the intersection of the two plates as the axis to facilitate the recovery of the folding plate to the platform plate.

[0077] Depend on Figure 1-4 It can be seen that the lifting component 24 includes a gear hole 241, a lifting plate 243, an adjusting member 242 for inserting the gear hole 241 to adjust the lifting plate 243, a locking rod 244, a screw 245, nuts 246 provided at both ends of the screw 245, a movable rod 247 with one end provided on the nut 246 and the other end provided on the lifting plate 243, and a connecting rod 248 provided in the horizontal direction of the screw.

[0078] The gear hole 241 is arranged on the long side of the platform plate and is connected to a screw rod inside. An external adjustment component can be inserted into the gear hole and rotated, thereby realizing fine adjustment of the lifting height of the lifting plate 243.

[0079] The adjusting member 242 includes a crank 2421 for realizing quick adjustment of the lifting plate and a knob 2422 for realizing fine adjustment of the lifting plate.

[0080] The lifting plate 243 is arranged at the upper part of the front end of the platform plate and horizontally overlaps with the platform plate. As the bearing part of the damper, the upper surface of the lifting plate is provided with a plurality of evenly arranged rollers and locking holes, and the lower surface is connected to the movable rod, which can play a role in vertical position transportation of the damper.

[0081] The locking rod 244 is a metal component that is thick at the top and thin at the bottom, and is used to be inserted into the locking hole on the lifting plate to limit the horizontal position movement of the damper on the lifting plate, thereby ensuring safety during the lifting process.

[0082] The screw rod 245 is arranged at the front end of the platform plate, one end of the screw rod 245 is fixedly connected to the side wall of one end of the platform plate 231, and the other end of the screw rod 245 is connected to the gear hole 241 at the other end of the platform plate 231. In addition, the screw rod is also connected to the connecting rod 248 and the movable rod 247. The nut 246 is arranged on the screw rod, and can rotate with the rotation of the gear hole, driving the connecting rod and the movable rod to move accordingly.

[0083] The movable rod 247 is arranged in the vertical direction of the screw rod 245, and can move in the vertical direction as the nut rotates, thereby driving the lifting plate to move up and down in the vertical direction. In actual operation, multiple groups of movable rods are arranged.

[0084] The connecting rod 248 is arranged in the horizontal direction of the screw rod 245, and can move horizontally with the rotation of the nut, driving the multiple groups of movable rods arranged on the front end of the platform plate to move synchronously, thereby ensuring the stability of the lifting plate when it is lifted or lowered.

[0085] The auxiliary unit 3 includes a baffle 32, which is a protective isolation device arranged on the outer surface (wall) after the damper is installed. The switching mode can be selected according to actual use requirements, such as flat opening, push-pull, and flip-up. The appearance color of the baffle should be consistent with the appearance color of the upper and lower cantilever walls of the damper, and it should be marked prominently so that the damper installation position can be quickly found for maintenance.

[0086] When the damper 4 is installed outdoors, the auxiliary unit 3 also includes a canopy 31 arranged on the outer wall of the damper. The canopy 31 is used to shade the damper from the sun and rain, effectively preventing the erosion of the damper outer wall baffle by rain and light, ensuring that the damper will not be affected by the external environment and reduce its service life. At the same time, its water-facing surface is designed with a slope to ensure that no water accumulation will occur.

[0087] The auxiliary unit 3 also includes a filling wall 33 and a lintel 34. The filling wall 33 is a wall of a frame structure, which plays a role of enclosure and separation. The cantilever wall installed with the damper is often closely attached to the filling wall in actual engineering; the lintel 34 is a prefabricated reinforced concrete beam arranged above the opening area of ​​the filling wall, and its function is to bear the upper load and ensure the stability of the wall.

[0088] In another embodiment of the present invention, a multifunctional handling method for a building damper is provided, the steps are as follows:

[0089] S100: Forming of lower cantilever wall: First, locate the lower floor beam, then use a high-precision total station to determine the position of the lower cantilever wall and its lower floor beam, and insert positioning steel bars at the intersection of the lower cantilever wall edge lines. Based on this, install the prefabricated lower cantilever wall steel bars on the lower floor beam, and then locate the upper floor beam and the upper cantilever wall in turn. According to the measured lower cantilever wall position, install the prefabricated lower cantilever wall steel bars on the lower floor beam, ensuring that the relative position relationship between the upper cantilever wall and the lower cantilever wall is accurate, thereby ensuring the installation accuracy of the damper.

[0090] S200: Forming of upper cantilever wall: After completing the installation of the lower cantilever wall reinforcement and pouring the lower floor slab, tie the upper floor slab reinforcement according to the design drawing, accurately locate the main beam and formwork position of the upper cantilever wall, install the upper cantilever wall reinforcement, embedded parts and protective layer pads, and then pour concrete; after the settlement is stable, remove the formwork and clean the embedded parts; finally, after the upper floor slab support frame is removed, install the lower cantilever wall support embedded parts, clean and pour concrete, and complete all cleaning work.

[0091] In step S200, since the upper cantilever wall is located directly below the upper floor beam, for the convenience of construction, the assembled upper cantilever wall reinforcement can be first installed on the upper cantilever wall formwork, and then the upper floor beam reinforcement can be installed. After the upper support embedded parts, upper cantilever wall reinforcement, and protective layer pads are installed, the formwork is cleaned and the last cantilever wall formwork is sealed.

[0092] Optionally, after installing the upper floor slab, upper cantilever wall reinforcement and formwork, the concrete with small aggregate should be used as much as possible during pouring and vibrated evenly and fully to ensure the quality of the molding. After 14 days of pouring, when the settlement tends to be uniform, the upper cantilever wall formwork can be removed, and the concrete on the surface of the upper support embedded parts on the lower surface of the upper cantilever wall should be cleaned to ensure that the surface of the upper support embedded parts is clean and tidy. After the upper floor slab support frame is removed, the lower support embedded parts of the lower cantilever wall are installed. During installation, pay attention to verify that the installation position of the lower support embedded parts is in the opposite direction and elevation of the upper support embedded parts on the cantilever wall, and ensure that the vertical distance between the upper support embedded parts and the lower support embedded parts is ≥ the minimum height required for the damper installation of 400mm.

[0093] S300: Treatment of reserved openings in the infill wall: To facilitate welding during damper installation and later damper replacement, half-thick masonry is used for construction of the infill wall near the cantilever wall and the damper installation area. To ensure the safety and stability of the opening, a lintel is set above the reserved opening, providing ample working space.

[0094] S400: Damper installation: In the order of "lower support - damper - upper support", each component is positioned on the embedded parts of the lower cantilever wall and the upper cantilever wall in turn through the handling and installation device and the winch. During this period, the height is fine-tuned and fixed by using the lifting plate, crank handle and knob. The locking rod is used to prevent the damper from rolling. Finally, the connection and installation of all components are completed by connecting steel pins.

[0095] Specifically, according to the installation order of "lower support - damper - upper support", the folding plate of the transport and installation device is rotated to the ground through the hinge connected to the front end of the platform plate, and the wire rope of the winch is tied to the lower support, and the winch is started to pull the lower support to the lifting plate at the front end of the device. First, turn the crank of the device to lift the lifting plate to the vicinity of the upper surface of the lower cantilever wall of the damper, and then replace the crank with the knob, and fine-tune the height of the lifting plate by the knob to ensure smooth removal of the lower support, remove the lower support, weld the lower support to the lower support embedded part on the upper surface of the lower cantilever wall. After welding, follow the same steps to transport the damper to the upper surface of the lower cantilever wall. To prevent the damper from rolling and falling, the locking rod can be inserted into the locking hole to limit the movement of the damper on the lifting plate. Then use the connecting steel pin to connect one end of the damper to the lower support. Finally, install the upper support to the upper support embedded part on the lower surface of the upper cantilever wall according to the steps, and connect it to the other end of the damper to complete the installation.

[0096] S500: When the damper needs to be replaced, open the baffle, move the damper handling and installation device to the cantilever wall below the damper, place the front end of the device close to the cantilever wall, shake the handle to lift the lifting plate at the front end of the device to the upper surface of the cantilever wall, remove the steel pins connecting the damper to the upper and lower supports, drag the damper onto the lifting plate, lower the lifting plate, unload the replaced damper to the ground, replace it with a new damper, and complete the replacement according to the installation steps.

[0097] Specifically, when installing the prefabricated lower cantilever wall reinforcement to the lower floor beam, it is necessary to calculate the height of the cantilever wall reinforcement extending from the floor beam surface. The calculation method is as follows:

[0098]

[0099] H 上 ,: bottom elevation of upper floor beam;

[0100] H 下 : Top elevation of lower floor beam;

[0101] H 阻尼器预留 : The reserved height required for damper installation (400mm);

[0102] H 保护层 : Thickness of concrete cover;

[0103] H 悬臂墙 : Height of cantilever wall;

[0104] H 钢筋伸出 : The height of the cantilever wall reinforcement extending from the surface of the floor beam.

[0105] The method of the present invention fundamentally avoids potential accumulation of construction errors by first casting the upper cantilever wall, then casting the lower cantilever wall, and finally installing the damper in the construction sequence, ensuring that the damper can be accurately and stably installed in the predetermined vertical direction.

[0106] Specifically, if the traditional sequence of first casting the lower cantilever wall and then casting the upper cantilever wall is adopted, since once the lower cantilever wall is cast, its position is relatively fixed. If the upper cantilever wall cast subsequently deviates from the lower cantilever wall in the vertical direction, it will be extremely difficult to correct it. This is because the upper part of the steel bars of the upper cantilever wall needs to be buried in the beam reinforcement of the upper floor slab, and the position of the beam reinforcement of the upper floor slab is pre-designed and fixed, and cannot be easily changed. If this deviation cannot be adjusted in time, it will directly lead to the inability of the damper to be accurately aligned with the upper and lower cantilever walls during installation, thereby affecting its shock absorption effect and even posing a threat to the safety of the entire structure. In contrast, the construction sequence adopted by the present invention effectively avoids this risk. Casting the upper cantilever wall first means that its position and shape can be used as a reference in the subsequent construction process, ensuring that the lower cantilever wall cast subsequently can be accurately aligned with it in the vertical direction. Even if a slight deviation is found during the pouring of the lower cantilever wall, there is still a large room for adjustment. The construction workers can adjust the position of the lower cantilever wall by bending the steel bars of the lower cantilever wall, expanding the embedded steel bars, and other flexible means to make it perfectly aligned with the upper cantilever wall. This adjustment is not only relatively easy to operate, but also ensures that the damper can be accurately positioned in the predetermined vertical direction during installation, so as to give full play to its shock absorption performance.

[0107] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
