Abstract
Description
Technical Field
[0001] This invention relates to the field of building engineering technology, specifically to a wall-type damper cantilever wall construction device and construction method. Background Technology
[0002] In the field of building engineering, with the continuous development of high-rise, super high-rise buildings and large-span spatial structures, the problem of vibration control of structures under wind loads and seismic actions has become increasingly prominent. As a highly efficient passive energy dissipation device, wall dampers, with their large-tonnage damping force output capacity, flexible spatial adaptability, and good synergy with the main structure, have become a key technical means to solve the problem of wind vibration and seismic response control of structures, and are widely used in various building structures with high requirements for seismic and wind resistance.
[0003] The normal operation of a wall-type damper depends on the construction quality of its mounting base—the cantilever wall—especially the positioning accuracy and structural integrity of the upper and lower cantilever walls. Traditional cantilever wall construction for wall-type dampers involves separate construction of the upper and lower cantilever walls: first, the reinforcement binding, embedded part fixing, and formwork installation of the upper cantilever wall are completed; then, the upper cantilever wall and the frame beams, slabs, and columns of the main structure are poured in one go; after the upper cantilever wall concrete has cured, the formwork installation, reinforcement binding, and concrete pouring of the lower cantilever wall are carried out. However, this process has several technical drawbacks: First, the long interval between pouring the upper and lower cantilever walls makes them susceptible to misalignment and axial displacement due to factors such as construction environment, formwork deformation, and concrete shrinkage. This directly leads to difficulties in installing the dampers, requiring additional repairs and adjustments, significantly increasing maintenance costs. Second, during the phased pouring process, improper treatment of construction joints at the connection between the upper and lower cantilever walls can result in defects such as grout leakage, honeycombing, and pitting, reducing the overall structural strength of the cantilever wall and affecting the energy dissipation effect of the dampers. Third, the phased construction process is cumbersome, requiring multiple formwork disassembly and assembly, reinforcement adjustment, and concrete curing. This not only prolongs the construction period but also increases labor and material inputs, leading to higher construction costs and lower construction efficiency. Furthermore, the traditional process lacks precise positioning and fixing measures for embedded parts, which are prone to displacement or warping during concrete pouring, resulting in unevenness between the embedded parts and the cantilever wall surface, further exacerbating the difficulty of damper installation. Meanwhile, during the phased pouring process, the formwork systems of the upper and lower cantilever walls are independent of each other, making it impossible to form a unified positioning benchmark. This makes it difficult to control the verticality and flatness of the upper and lower walls, and thus difficult to meet the stringent requirements of modern buildings for the installation accuracy of dampers.
[0004] Therefore, there is an urgent need for a wall-type damper cantilever wall construction technology that can achieve simultaneous construction of upper and lower cantilever walls, ensure positioning accuracy, improve construction efficiency, and reduce costs, in order to solve the above-mentioned problems existing in the current process. Summary of the Invention
[0005] Traditional wall-type damper cantilever walls are constructed using a step-by-step pouring method, which suffers from drawbacks such as easy misalignment and axial displacement between the upper and lower walls, leading to difficulties in damper installation and high maintenance costs. The step-by-step pouring also creates construction joints, which are prone to defects such as grout leakage and honeycombing, reducing structural strength. Furthermore, the construction process is cumbersome, requiring multiple disassemblies and reassemblies of formwork and concrete curing, resulting in long construction periods, high labor and material costs, and low efficiency. Additionally, the lack of precise positioning measures for embedded parts makes them prone to displacement and warping, further affecting the installation accuracy of the damper. This invention provides a construction device and method for wall-type damper cantilever walls, achieving integrated molding of the upper and lower cantilever walls, solving the problems of misalignment and grout leakage, improving construction accuracy and efficiency, reducing costs, and ensuring the stability of the damper installation foundation.
[0006] The solution adopted by the present invention to solve its technical problem is: a wall-type damper cantilever wall construction device, including a template group and a frame module group. The template group is a rectangular module with openings at the top and bottom. A rectangular frame opening is left in the middle of the template group. The template group is divided into an upper cantilever wall casting area and a lower cantilever wall casting area by the rectangular frame opening. Steel mesh is tied in the upper cantilever wall casting area and the lower cantilever wall casting area. Embedded parts are tied and fixed on the opposite sides of the opposite surfaces of the upper cantilever wall casting area and the lower cantilever wall casting area by steel mesh.
[0007] The frame module is placed into the template group through a rectangular frame opening and positioned. The upper and lower mold bases of the frame module serve as the bottom and top templates for the upper and lower cantilever walls, respectively. A passageway is left between the left and right templates of the frame module and the side templates of the template group to connect the upper and lower cantilever wall pouring areas. During concrete pouring, the upper and lower cantilever wall pouring areas are poured synchronously through the passageway, achieving the effect of integrally casting the upper and lower cantilever walls. After the upper and lower cantilever walls are poured, a damper is installed between the upper and lower cantilever walls through embedded parts.
[0008] Furthermore, the template group includes an outer template, an inner template, and two side templates. The outer template, inner template, and two side templates are assembled to form a complete rectangular module. The rectangular frame opening is located in the middle of the outer template and the inner template.
[0009] Furthermore, the frame module includes an upper mold base and a lower mold base, which are symmetrically arranged U-shaped structures and are slidably fitted together. A first adjustment component for controlling the distance between the upper and lower mold bases is vertically arranged between them. Grooves are opened outward on the left and right side plates of the upper and lower mold bases, and movable templates are matched and arranged in the grooves. A second adjustment component for controlling the displacement of the movable templates is horizontally arranged between the left and right side plates of the frame module.
[0010] Furthermore, the first adjustment component consists of a vertical screw and a vertical helical tube. The inner sides of the upper mold base and the lower mold base are symmetrically fixed with vertical screws of opposite thread directions. The opposite ends of the vertical screws are connected together by the vertical helical tube. The first adjustment component is set at the diagonal of the frame module, and its position corresponds to the embedded part.
[0011] The second adjustment component consists of a horizontal screw and a horizontal helical tube. Horizontal screws with opposite thread directions are vertically fixed on the inner side of the movable templates on both sides. The horizontal screws are movably inserted through the through hole of the lower mold base, and the opposite ends of the horizontal screws are connected together by the horizontal helical tube.
[0012] Furthermore, the upper mold base is provided with two sets of downwardly extending guide rods, the movable template is provided with two sets of inwardly extending guide rods, and the lower mold is fixedly installed with a guide seat. The guide seat has guide holes that match and correspond to the guide rods one and two. The guide rods one and two are inserted into the guide holes on the guide seat to achieve limiting and guiding.
[0013] A method for constructing a cantilever wall with a wall damper using the above-mentioned construction device includes the following steps:
[0014] S1. Template assembly installation: Measure and lay out the lines according to the design drawings to determine the location of the cantilever wall and the installation position of the embedded parts. Position and fix the template assembly to ensure that the rectangular frame opening in the middle of the template assembly is located between the upper and lower cantilever walls, forming the upper cantilever wall pouring area and the lower cantilever wall pouring area, and reserve the inner template.
[0015] S3. Reinforcing mesh binding and embedded part installation: Bind the reinforcing mesh in the upper cantilever wall casting area and the lower cantilever wall casting area respectively, and fix the embedded parts on the reinforcing mesh on the opposite side, and then close the inner formwork;
[0016] S4. Frame module installation and positioning: Place the frame module into the template group through the rectangular frame opening, and use the movable template for initial positioning so that the frame module is located in the center of the rectangular frame opening, ensuring that the diameter of the channel openings on both sides is consistent.
[0017] S5. Frame module adjustment: Retract the movable template to serve as the side template of the passageway; adjust the distance between the upper and lower template bases to ensure they are tightly fitted with the embedded parts of the upper and lower cantilever walls, respectively, serving as the bottom template of the upper cantilever wall and the top template of the lower cantilever wall.
[0018] S6. Concrete pouring: Concrete is poured simultaneously in the upper cantilever wall pouring area and the lower cantilever wall pouring area, and then vibrated to achieve the integral molding of the upper and lower cantilever walls.
[0019] S7. Formwork Removal and Damper Installation: After the concrete strength reaches the design requirements, remove the formwork assembly and frame assembly, cut off the plain concrete part at the passage entrance, and finally install the wall-type damper through the embedded parts to complete the construction.
[0020] Furthermore, in step S4, the second adjustment component drives the horizontal screw by rotating the horizontal solenoid, controlling the horizontal movement of the movable template to achieve channel opening width adjustment and template positioning; in step S5, the first adjustment component drives the upper and lower vertical screws simultaneously by rotating the vertical solenoid, achieving precise adjustment of the distance between the upper mold base and the lower mold base.
[0021] Furthermore, in step S7, when the frame module is dismantled, the distance between the upper mold base and the lower mold base is reduced by the first adjustment component, so that a gap is created between the frame module and the upper or lower cantilever wall, which facilitates the smooth removal of the whole from the rectangular frame opening and achieves non-destructive demolding.
[0022] The beneficial effects of this invention are:
[0023] This invention constructs an integrated construction system for upper and lower cantilever walls through the collaborative design of template groups and frame modules. The rectangular frame opening in the middle of the template group provides a unified positioning benchmark for the pouring area of the upper and lower cantilever walls. The initial positioning of the movable template can accurately place the frame module in the center of the rectangular frame opening, ensuring that the diameter of the two side passage openings is consistent. At the same time, the first adjustment component can drive the upper and lower formwork bases to fit tightly with the embedded parts, so that the upper formwork base and the lower formwork base serve as the bottom formwork of the upper cantilever wall and the top formwork of the lower cantilever wall, respectively. This effectively avoids the problems of non-coincidence of the upper and lower wall planes and misalignment of the axis caused by the independent positioning of the templates in traditional step-by-step construction, and provides a reliable guarantee for the accurate installation of the dampers in the future.
[0024] After the movable template of the frame module is retracted, it can be used as the side template of the passage entrance, so that the casting areas of the upper and lower cantilever walls can be connected to each other, and the upper and lower cantilever walls can be cast at the same time. There is no need to wait for the upper cantilever wall to cure and form before the lower cantilever wall is constructed. This eliminates the construction joints in traditional step-by-step construction, reduces structural defects such as honeycomb, pitting, and delamination caused by improper treatment of construction joints, significantly improves the overall structural strength and density of the cantilever wall, and greatly shortens the construction period.
[0025] The frame module integrates positioning, adjustment, support and dismantling functions, making installation and dismantling operations simple. During dismantling, the distance between the upper and lower formwork bases can be reduced by the first adjustment component to achieve non-destructive removal. It can be reused, reducing the consumption and replacement frequency of formwork materials. In addition, synchronous construction reduces the manual input of formwork dismantling and secondary adjustment of reinforcement. The channel design facilitates the rapid pouring and vibration of concrete, further improving construction efficiency. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0035] Please see Figure 1-7 This invention provides a technical solution for a construction device and method for a wall-type damper cantilever wall:
[0036] Example 1:
[0037] This embodiment provides a construction device for the simultaneous casting and forming of upper and lower cantilever walls, aiming to solve problems such as misalignment of upper and lower walls, displacement of embedded parts, and poor forming quality in traditional step-by-step casting methods. The device includes two parts: a template assembly and a frame template assembly 7. The template assembly forms the outer forming boundary of the cantilever wall, while the frame template assembly 7 serves as an intermediate template system between the upper and lower cantilever walls, taking into account positioning, support, adjustment, and demolding functions, thereby realizing the integrated construction of the upper and lower walls.
[0038] like Figure 1 and Figure 2As shown, the template assembly consists of an outer template 1, an inner template 2, and two side templates 3, forming a rectangular structure with openings at the top and bottom. During assembly, it is necessary to ensure that the templates are tightly connected to avoid grout leakage during subsequent pouring. In the middle of the template assembly, rectangular openings 6 are made on the outer template 1 and the inner template 2. The rectangular openings 6 divide the template assembly into an upper cantilever wall pouring area and a lower cantilever wall pouring area. The spatial dimensions of the two pouring areas must be strictly determined according to the specifications of the cantilever wall in the design drawings to meet the forming requirements of the upper cantilever wall 10 and the lower cantilever wall 11. The rectangular openings 6 are not only the dividing structure for concrete pouring, but also the key channel for the installation and positioning of the frame module 7. Within the upper and lower cantilever wall pouring areas, steel mesh 4 is tied according to the reinforcement design. The spacing, quantity, and binding strength of the steel mesh must meet the building structure strength standards. At the same time, on opposite sides of the two pouring areas, embedded parts 5 are tied and fixed with steel mesh 4. These embedded parts 5 are used for the later installation and fixing of dampers 9. The material and thickness of the embedded parts must match the installation load requirements of the dampers. It is essential to ensure that their position is accurate and that they fit tightly with the formwork system to prevent displacement or grout leakage during concrete pouring, while also providing a stable installation base for the dampers.
[0039] The frame module 7 is a key component for achieving synchronous pouring and precise positioning of the upper and lower cantilever walls. It is inserted into the template assembly through the rectangular frame opening 6 and positioned accordingly. Figures 4-6 As shown, the overall structure of the frame module 7 includes an upper mold base 702, a lower mold base 701, a movable template 704, a first adjustment component, and a second adjustment component. Both the upper mold base 702 and the lower mold base 701 are designed as symmetrical U-shaped structures, and they slide and fit together to ensure the stability of the upper mold base 702 when moving vertically relative to the lower mold base 701, preventing offset. At opposite corners of the frame module 7, a first adjustment component is vertically arranged. The first adjustment component consists of a vertical screw 707 and a vertical helical tube 708. Vertical screws 707 with opposite thread directions are symmetrically fixed to the inner sides of the upper mold base 702 and the lower mold base 701, and the opposite ends of the vertical screws 707 are threadedly connected through the vertical helical tube 708. The arrangement of the first adjustment component... The position corresponds to the embedded part 5. By rotating the vertical screw tube 708, the two vertical screws 707 can be driven to move synchronously in opposite directions, thereby precisely adjusting the distance between the upper mold base 702 and the lower mold base 701. This allows the upper mold base 702 to fit tightly against the embedded part 5 in the casting area of the upper cantilever wall 10, and the lower mold base 701 to fit tightly against the embedded part 5 in the casting area of the lower cantilever wall 11. At this time, the upper mold base 702 can serve as the bottom template of the upper cantilever wall 10, and the lower mold base 701 can serve as the top template of the lower cantilever wall 11, effectively ensuring the plane overlap of the upper and lower cantilever walls 11 after molding.
[0040] On the left and right side plates of the upper mold base 702 and the lower mold base 701, grooves 703 are provided outward. Movable templates 704 are matched and arranged in the grooves 703. The movable templates 704 can slide horizontally in the grooves 703. Between the left and right side plates of the frame module 7, a second adjustment component is horizontally arranged. This component consists of a horizontal screw 705 and a horizontal screw tube 706. The inner sides of the movable templates 704 on both sides are vertically fixed with horizontal screws 705 with opposite thread directions. The horizontal screws 705 are movably inserted through the through hole of the lower mold base 701, and their opposite ends are threadedly connected by the horizontal screw tube 706. By rotating the horizontal helical tube 706, the horizontal screw 705 can be driven to extend or retract the movable template 704. When the movable template 704 extends and abuts against the side template 3 of the template assembly, the mutual abutment force on both sides can position the frame module 7 at the center of the rectangular frame opening 6, ensuring that the diameter of the channel opening 12 formed between the left and right templates of the frame module 7 and the side template 3 is consistent. This channel opening 12 connects the upper cantilever wall pouring area and the lower cantilever wall pouring area, providing a stable channel for subsequent concrete pouring and vibration. When the movable template 704 retracts into the groove 703, it can serve as the side template of the channel opening 12, preventing concrete from overflowing from the side of the channel opening 12 during pouring. Anti-slip washers 712 are fitted on the outer walls of both the horizontal helical tube 706 and the vertical helical tube 708.
[0041] To further enhance the stability of the frame module adjustment process, two sets of downward-extending guide rods 710 are longitudinally arranged on the upper mold base 702, and two sets of inward-extending guide rods 711 are horizontally arranged on the movable template 704. A guide seat 709 is fixedly installed on the lower mold base 701. The guide seat 709 has guide holes that match the guide rods 710 and 711. The guide rods 710 and 711 are respectively inserted into the corresponding guide holes to form a limiting and guiding structure, which restricts the offset direction of the upper mold base 702 when it moves vertically and the offset direction of the movable template 704 when it moves horizontally, ensuring the adjustment accuracy of the first adjustment component and the second adjustment component, thereby ensuring the forming quality of the upper and lower cantilever walls 11.
[0042] This device achieves the technical effects of simultaneous casting of upper and lower cantilever walls, precise positioning, high forming quality, and significantly improved construction efficiency through the coordinated work of the template group and the frame module 7. The frame module integrates positioning, adjustment, support, and demolding, with a compact structure and simple operation, making it particularly suitable for structural engineering projects with high requirements for damper installation accuracy.
[0043] Example 2:
[0044] Based on Embodiment 1, this embodiment provides a construction method for a cantilever wall using a wall-type damper employing the construction device described in Embodiment 1. This method achieves simultaneous pouring of the upper and lower cantilever walls through a standardized process. The specific steps are as follows:
[0045] First, the formwork assembly is installed: Before construction, measurements and layout are carried out according to the design drawings. Professional measuring instruments are used to determine the construction position, dimensional parameters, and installation position of the embedded parts 5 of the cantilever wall, ensuring that the layout accuracy meets the building codes. Then, the outer formwork 1 and the side formwork 3 are positioned and fixed in sequence. During fixing, bolts are used in combination with the supporting structure to ensure the overall stability of the formwork assembly. At this time, the inner formwork 2 should be left uninstalled to reserve operating space for the subsequent binding of the steel mesh 4 and the installation of the embedded parts 5. At the same time, it is ensured that the rectangular frame 6 in the middle of the formwork assembly is accurately located between the upper cantilever wall 10 and the lower cantilever wall 11, clearly delineating the upper cantilever wall pouring area and the lower cantilever wall pouring area.
[0046] Next, the steel mesh 4 is tied and the embedded parts 5 are installed: In the upper and lower cantilever wall pouring areas, the steel mesh 4 is tied according to the reinforcement requirements of the design drawings. The lap length and tying node spacing of the steel mesh 4 must strictly follow the specifications to ensure the structural strength of the steel mesh 4 skeleton. After the steel mesh 4 is tied, the embedded parts 5 are fixedly installed on the steel mesh on the opposite sides of the two pouring areas. Before installation, the edge line of the embedded part 5 should be marked on the corresponding position of the formwork group with a red or blue pencil or ink line, so that the edge line of the embedded part 5 coincides with the longitudinal and transverse center lines of the formwork group to determine its planar position. After installation, the fit between the embedded part 5 and the formwork should be checked. If the embedded part 5 is warped or the formwork is deformed, it should be corrected in time to ensure that the two fit tightly without gaps, so as to avoid concrete seeping into the gaps and forming voids during subsequent pouring. Finally, the inner formwork 2 is closed, and the connection between the inner formwork 2 and the outer formwork 1 and the side formwork 3 is checked to prevent grout leakage.
[0047] Next, the frame module 7 is installed and positioned: the assembled frame module 7 is placed into the template group through the rectangular frame opening 6. At this time, by rotating the horizontal screw tube 706 of the second adjusting component, the horizontal screw 705 is driven to extend the movable template 704 outward until the movable template 704 is tightly abutting against the side template 3 of the template group. During this process, the guide rod 711 slides horizontally along the guide hole of the guide seat 709 to guide the movable template 704, ensuring that the movable templates 704 on both sides extend synchronously, thereby accurately positioning the frame module 7 at the center of the rectangular frame opening 6, so that the diameter of the channel opening 12 formed between the left and right sides of the frame module 7 and the side template 3 is consistent. This diameter needs to meet the operation requirements of concrete pouring and vibration equipment, and is usually controlled at about 7cm.
[0048] Then, the frame module 7 is adjusted: the horizontal screw tube 706 is rotated again, so that the horizontal screw 705 drives the movable template 704 to retract into the groove 703. At this time, the movable template 704 serves as the side template of the channel opening 12, sealing the side gap of the channel opening 12. Then, the vertical screw tube 708 of the first adjustment component is rotated. Since the vertical screw 707 has the opposite thread direction, it will drive the upper mold base 702 to move downward and the lower mold base 701 to move upward, adjusting the distance between the two. During this process, the guide rod 710 slides vertically along the guide hole of the guide seat 709, providing guidance for the upper mold base 702, ensuring that the upper mold base 702 smoothly fits the embedded part 5 of the upper cantilever wall pouring area and the lower mold base 701 smoothly fits the embedded part 5 of the lower cantilever wall pouring area. At this time, the upper mold base 702 becomes the bottom template of the upper cantilever wall 10 and the lower mold base 701 becomes the top template of the lower cantilever wall 11, completing the template preparation work before the pouring of the upper and lower cantilever walls 11.
[0049] The next step is concrete pouring: concrete is poured simultaneously in the upper cantilever wall pouring area and the lower cantilever wall pouring area. At the same time, the vibrating equipment is inserted into the two pouring areas through the channel 12 to vibrate. During the vibration process, the pouring area must be evenly covered to ensure that the concrete is dense, reduce air bubbles and voids, and improve the structural strength of the cantilever wall. Since the channel 12 has the same diameter and is symmetrically positioned, the uniform distribution of concrete in the two pouring areas can be guaranteed, realizing the integral molding of the upper cantilever wall 10 and the lower cantilever wall 11, effectively avoiding the misalignment problem of the upper and lower walls caused by traditional staged pouring.
[0050] Finally, demolding and damper 9 installation are carried out: After the concrete has cured to the design strength, the formwork assembly is removed first: the inner formwork 2, outer formwork 1, and side formwork 3 are removed in sequence. During the removal process, avoid forceful operation to prevent damage to the cantilever wall surface; then, the frame formwork 7 is removed: the vertical screw tube 708 is rotated to reduce the distance between the upper formwork base 702 and the lower formwork base 701, creating gaps between the upper formwork base 702 and the upper cantilever wall 10, and between the lower formwork base 701 and the lower cantilever wall 11. At this point, the entire frame formwork 7 can be removed from the rectangular frame opening 6. This process enables non-destructive demolding, allowing the frame modules to be recycled and reused, thus reducing construction costs. Next, the plain concrete portion at the passage entrance 12 is manually removed, ensuring the cantilever wall surface remains flat during the removal process to avoid damaging the main structure. Once the cantilever wall structure has fully met the design requirements, the embedded parts 5 within the upper and lower cantilever walls 11 are used as the installation base. The mounting base 8 is then welded and fixed onto the mounting base, and the damper 9 is fixed onto the mounting base 8 according to the construction specifications, completing the installation of the damper 9 and ultimately achieving the construction of the wall-type damper cantilever wall.
[0051] This construction method, through the integrated design and precise adjustment of the frame module, enables the synchronous pouring of the upper and lower cantilever walls. This not only improves construction efficiency and reduces the time consumption of traditional phased construction, but also effectively solves the problems of easy displacement and grout leakage of the upper and lower cantilever walls through multiple positioning and guiding structures, ensuring project quality and providing a reliable guarantee for the stable installation and use of the dampers in the future.
[0052] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
