Description

Technical Field

[0001] The present invention relates to the technical field of construction energy dissipation and seismic reduction engineering; specifically, it is a construction method for installing a viscous damper wall. Background Art

[0002] Common energy dissipation and seismic reduction technologies in high-rise buildings include displacement dampers, velocity-type damper walls, and tuned dampers. Compared with other types of dampers, the velocity-type viscous damper has stable performance and is widely recognized in the engineering field.

[0003] The viscous damper wall can obtain good seismic reduction effects for both wind loads and seismic actions. The parameters of the damper wall can be freely designed according to the building scale and seismic reduction requirements. The viscous body in the damper wall has high durability and is not prone to change. Moreover, the product can be installed in the wall without affecting the building's use function. Due to these many advantages, it has been widely used in building seismic reduction.

[0004] The installation construction of the viscous damper wall needs to be carried out after the completion of the main structure, that is, during the construction within the floor, and it is impossible to use vertical transportation equipment such as tower cranes for hoisting and installation. Since the weight of a single component of the viscous damper wall is relatively large, it often exceeds the scope of human strength, making the construction difficult, and both the installation quality and construction safety of the damper wall cannot be guaranteed.

[0005] Therefore, a construction method that is convenient for installing the viscous damper wall is needed now.

[0006] After retrieval, CN113089874A - Viscous Damper Wall for Steel Structure Buildings does not provide inspiration for solving the above technical problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a construction method that is convenient for installing a viscous damper wall.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0009] A construction method for installing a viscous damper wall, the construction method comprising the following steps:

[0010] S1: Installation of embedded parts; install the upper embedded steel plate in the upper reinforced concrete of the wall main structure; install the lower embedded steel plate in the lower reinforced concrete of the wall main structure;

[0011] S2: Positioning and setting out lines: Mark the installation side lines on the upper embedded steel plate and the lower embedded steel plate in S1;

[0012] S3: Installation of the upper connecting secondary beam; install the upper connecting secondary beam onto the upper embedded steel plate;

[0013] S4: Installation of the lower connecting secondary beam; install the lower connecting secondary beam onto the lower embedded steel plate;

[0014] S5: Installation of viscous damping wall; connecting the outer steel box in the viscous damping wall to the lower connecting secondary beam and connecting the inner steel plate in the viscous damping wall to the upper connecting secondary beam; then injecting viscous damping material between the outer steel box and the inner steel plate.

[0015] In step S1, during the construction of the lower-layer reinforced concrete of the wall main structure, according to the designed position of the viscous damping wall, lower embedded steel plates are pre-embedded at the top of the lower-layer reinforced concrete, and the bottom of the lower embedded steel plates is connected to the lower anchor bars and connected to the lower-layer reinforced concrete; during the construction of the upper-layer reinforced concrete of the main structure, it is required to pre-embed upper embedded steel plates at the lower end of the upper-layer reinforced concrete, and the top of the upper embedded steel plates is connected to the upper anchor bars and connected to the upper-layer reinforced concrete.

[0016] During the construction of the upper-layer reinforced concrete, embedded sleeves are arranged in the upper-layer reinforced concrete to form reserved holes penetrating the upper-layer reinforced concrete.

[0017] One or more reserved holes are provided in the upper-layer reinforced concrete; and the predicted holes are provided above the upper embedded steel plates.

[0018] In step S2, according to the designed position of the viscous damping wall, the outline of the lower connecting secondary beam is marked on the lower embedded steel plate, and then the outline of the upper embedded steel plate on the upper embedded steel plate is positioned based on the outline on the lower embedded steel plate.

[0019] The method of positioning the outline of the upper embedded steel plate based on the outline on the lower embedded steel plate is: using a laser plumb bob or a plumb line to hang a line, and casting the outline of the upper connecting secondary beam on the upper embedded plate; that is, casting the outline of the upper connecting secondary beam on the upper embedded steel plate.

[0020] In step S3, hoisting steel wires are threaded through the reserved holes, and the hoisting steel wires are connected with hoisting pulleys; the upper part of the hoisting pulley is hung on the above-mentioned hoisting steel wires; a chain block is threaded through the hoisting pulley; one end of the chain block is connected to a hook, and there is an upper hoisting hole on one of the upper stiffening ribs in the middle of the upper connecting secondary beam. The chain block is connected to a shackle through the connecting hook, and the shackle passes through the upper hoisting hole and is connected to the connecting hook; one hoisting pulley is provided on each side of the upper-layer reinforced concrete. After the two groups of hoisting pulleys are connected to the upper connecting secondary beam through the hooks and shackles, the chain blocks are pulled forward simultaneously, and the upper connecting secondary beam is slowly hoisted until the upper surface of the upper stiffening edge rib of the upper connecting secondary beam is close to the bottom surface of the upper embedded steel plate, aligning with the outline of the upper connecting secondary beam on the upper embedded steel plate, and after leveling, the top of the upper connecting secondary beam is welded firmly around the upper embedded steel plate.

[0021] In step S4, after the upper connecting secondary beam is installed in place, the chain block and the upper connecting secondary beam are removed, and then the chain block is connected to the lower connecting secondary beam. Subsequently, the chain block is pulled backward to align the lower connecting secondary beam with the upper edge line of the lower embedded plate, and then the bottom of the lower connecting secondary beam is welded firmly around the lower embedded steel plate.

[0022] In step S5, temporary lifting points are welded at the center of the outer steel box of the viscous damping wall; the chain hoist is connected to the temporary lifting points, and by pulling the chain hoist, the outer steel box and the inner steel plate of the viscous damping wall are pulled to the area between the upper connecting secondary beam and the lower connecting secondary beam; subsequently, the inner steel plate is connected to the upper connecting secondary beam; the outer steel box is connected to the lower connecting secondary beam, and then viscous damping material is injected between the outer steel box and the inner steel plate to complete the installation of the viscous damping wall.

[0041] S5: Installation of the viscous damping wall 400; connect the external steel box 401 in the viscous damping wall 400 to the lower connecting secondary beam 202 and connect the internal steel plate 402 in the viscous damping wall 400 to the upper connecting secondary beam 201; then inject viscous damping material between the external steel box 401 and the internal steel plate 402.

[0042] The present invention discloses a construction method for installing a viscous damping wall 400. The construction method disclosed by the present invention can effectively solve the installation construction problems of the viscous damping wall 400 in the floor, greatly improve the installation accuracy, and at the same time ensure the construction safety of the operators, and is economical, reasonable, fast and efficient, with strong practicability and good application prospects.

[0043] Further, in step S1 of the present invention, during the construction of the lower-layer reinforced concrete of the wall main structure, according to the designed position of the viscous damping wall 400, embed the lower embedded steel plate 102 at the top of the lower-layer reinforced concrete, and connect the lower anchor bar 104 to the bottom of the lower embedded steel plate 102 to connect with the lower-layer reinforced concrete; through such a design, the strength of the wall main structure can be increased; through the above operations, the structural strength of the lower-layer reinforced concrete can be increased. In addition, in the present invention, during the construction of the upper-layer reinforced concrete of the main structure, it is required to embed the upper embedded steel plate 101 at the lower end of the upper-layer reinforced concrete, and connect the upper anchor bar 103 to the top of the upper embedded steel plate 101 to connect with the upper-layer reinforced concrete; through the above design, the structural strength of the upper-layer reinforced concrete can be increased. At the same time, through the settings of the lower embedded steel plate 102 and the upper embedded steel plate 101 in the present invention, it is convenient for subsequent welding and fixing of the lower connecting secondary beam 202 and the upper connecting secondary beam 201.

[0044] Further, in the present invention, during the construction of the upper reinforced concrete, embedded sleeves are arranged in the upper reinforced concrete to form a reserved hole 105 penetrating the upper reinforced concrete; through the setting of the reserved hole 105, it is convenient to thread and hoist the lifting wire rope subsequently; that is, the setting of the reserved hole 105 enables connection points on the main structure of the wall, facilitating the hoisting of corresponding components as required; thus realizing the installation of the entire viscous damping wall 400.

[0045] Further, in the present invention, one or more reserved holes 105 are provided on the upper reinforced concrete; the number of reserved holes 105 provided here can be selected according to needs, and at the same time, it is required that the expected holes described in the present invention are arranged above the embedded steel plate 101; such a setting makes the connection between the lifting appliance 300 and the main structure of the wall in a high position area, facilitating the subsequent pulling and hoisting of each component of the viscous damping wall 400.

[0046] Further, in the present invention, in step S2, according to the position of the designed viscous damping wall 400, the outline of the lower connecting secondary beam 202 is marked on the lower embedded steel plate 102, and then the outline of the upper embedded steel plate 101 on the upper embedded steel plate 101 is positioned based on the outline on the lower embedded steel plate 102; through the setting of the outline of the lower connecting secondary beam 202 and the outline of the upper embedded steel plate 101, a good positioning effect is achieved, facilitating the installation and positioning of the lower connecting secondary beam 202 and the upper connecting secondary beam 201.

[0047] Further, in the present invention, the method of positioning the outline of the upper embedded steel plate 101 based on the outline on the lower embedded steel plate 102 is: using a laser plummet or a plumb line to hang a line, and projecting the outline of the upper connecting secondary beam 201 onto the upper embedded plate; that is, projecting the outline of the upper connecting secondary beam 201 onto the upper embedded steel plate 101; the above operation method facilitates the positioning of the upper and lower outlines; the reason for positioning the outline of the upper embedded steel plate 101 through the outline on the lower embedded steel plate 102 in the present invention is that the outline on the lower embedded steel plate 102 is on the lower embedded steel plate 102, which is convenient for manual preliminary positioning and greatly improves the positioning efficiency of the outline.

[0048] Further, in step S3 of the present invention, a hoisting steel wire rope is threaded through the reserved hole 105, and the hoisting steel wire rope is connected to a hoisting pulley; the upper part of the hoisting pulley is hung on the above-mentioned hoisting steel wire rope; a chain block 302 is threaded through the hoisting pulley; one end of the chain block 302 is connected to a hook 303, and an upper hoisting hole 207 is provided on a middle stiffening rib 205 of the upper connecting secondary beam 201. The chain block 302 is connected to a shackle 304 through the connecting hook 303. After the shackle 304 passes through the upper hoisting hole 207, it is connected to the connecting hook 303; a hoisting pulley is provided on each side of the upper reinforced concrete. After the two groups of hoisting pulleys are connected to the upper connecting secondary beam 201 through the hook 303 and the shackle 304, the chain block 302 is pulled forward simultaneously, and the upper connecting secondary beam 201 is slowly hoisted until the upper surface of the upper stiffening edge rib of the upper connecting secondary beam 201 is close to the bottom surface of the upper embedded steel plate 101, align the side line of the upper connecting secondary beam 201 on the upper embedded steel plate 101, and level it, then weld the top of the upper connecting secondary beam 201 and the periphery of the upper embedded steel plate 101 firmly; through the above operations, the hoisting of the upper connecting secondary beam 201 can be realized.

[0049] Meanwhile, in step S4 of the present invention, after the upper connecting secondary beam 201 is installed in place, the chain block 302 is removed from the upper connecting secondary beam 201, and then the chain block 302 is connected to the lower connecting secondary beam 202. Subsequently, the chain block 302 is pulled backward to align the lower connecting secondary beam 202 with the upper side line of the lower embedded plate, and then the bottom of the lower connecting secondary beam 202 and the periphery of the lower embedded steel plate 102 are welded firmly; through such a setting, the installation of the lower connecting secondary beam 202 is facilitated.

[0050] Through the above operations, it can be known that a lifting tool 300 (the lifting tool 300 mainly includes threading a hoisting steel wire rope through the reserved hole 105, the hoisting steel wire rope is connected to a hoisting pulley; the upper part of the hoisting pulley is hung on the above-mentioned hoisting steel wire rope; a chain block 302 is threaded through the hoisting pulley; one end of the chain block 302 is connected to a hook 303, an upper hoisting hole 207 is provided on a middle stiffening rib 205 of the upper connecting secondary beam 201, the chain block 302 is connected to a shackle 304 through the connecting hook 303, and after the shackle 304 passes through the upper hoisting hole 207, it is connected to the connecting hook 303; a hoisting pulley is provided on each side of the upper reinforced concrete. The two groups of hoisting pulleys are connected to the upper connecting secondary beam 201 through the hook 303 and the shackle 304) can simultaneously realize the installation of the upper connecting secondary beam 201 and the lower connecting secondary beam 202, greatly reducing the use of the lifting tool 300. The hoisting of the viscous damping wall 400 can be realized without changing the hoisting point, which not only reduces the use of components but also greatly improves the hoisting efficiency.

[0051] Further, in step S5 of the present invention, a temporary lifting point 404 is welded at the center of the outer steel box 401 outside the viscous damping wall 400; the chain hoist 302 is connected to the temporary lifting point 404, and by pulling the chain hoist 302, the outer steel box 401 and the inner steel plate 402 of the viscous damping wall 400 are pulled to the area between the upper connecting sub-beam 201 and the lower connecting sub-beam 202; subsequently, the inner steel plate is connected to the upper connecting sub-beam 201; the outer steel box 401 is connected to the lower connecting sub-beam 202, and then a viscous damping material is injected between the outer steel box 401 and the inner steel plate 402 to complete the installation of the viscous damping wall 400; through the above operations, the main body installation of the viscous damping wall 400 is facilitated.

[0052] Further, before hoisting the viscous damping wall 400 in the present invention, it is required that the inner steel plate 402 in the viscous damping wall 400 be connected to the outer steel box 401 by temporary spot welding (here, the temporary spot welding is also the temporary welding point); such a setting makes the inner steel plate 402 and the outer steel box 401 of the viscous damping wall 400 form an integral structure, facilitating the hoisting of the inner steel plate 402 and the outer steel box 401 together. After hoisting to the set position, the temporary welding points can be removed; and subsequent installation operations can be carried out.

[0053] Specifically:

[0054] A construction method for installing a viscous damping wall 400 according to the present invention includes the following steps: S1 Installation of embedded parts; S2 Positioning and setting out; S3 Installation of the upper connecting sub-beam 201; S4 Installation of the lower connecting sub-beam 202; S5 Installation of the viscous damping wall 400.

[0055] In the present invention, the connecting sub-beam 200 is mainly used for connecting the inner steel plate and the outer steel box of the viscous damping wall 400; the connecting sub-beam 200 mainly includes an upper connecting sub-beam 201 and a lower connecting sub-beam 202; the upper connecting sub-beam 201 and the lower connecting sub-beam 202 are symmetrically distributed at intervals up and down.

[0056] In addition, an embedded plate is provided in the main body structure of the wall in the present invention, and the embedded plate includes a lower embedded steel plate 102 and an upper embedded steel plate 101.

[0057] In step S1, when constructing the lower-layer reinforced concrete of the wall main body structure, according to the designed position of the viscous damping wall 400, the lower embedded steel plate 102 is embedded at the top of the lower-layer reinforced concrete, and the bottom of the lower embedded steel plate 102 is connected to the lower anchor bar 104; when installing the bottom formwork of the upper-layer concrete structural beam in the main body structure, according to the designed position of the viscous damping wall 400, the upper embedded steel plate 101 is embedded at the bottom of the upper-layer concrete structural beam, and the top of the upper embedded steel plate 101 is connected to the upper anchor bar 103.

[0058] During the construction of the upper-layer reinforced concrete of the main structure, embedded sleeves are pre-embedded in the concrete structural beams. After the formwork on the side of the beam is removed, a reserved hole 105 running through the width of the beam is formed for the use of passing the steel wire rope 305 during the construction of steps 3, 4, and 5. The reserved hole 105 is arranged in the upper-middle part of the upper embedded steel plate 101 to ensure hoisting balance.

[0059] In step S2, after the strength of the upper-layer concrete structural beam of the main structure reaches the requirement, the formwork at the bottom of the beam is removed, and the floating slurry, rust, etc. on the surfaces of the upper embedded steel plate 101 and the lower embedded steel plate 102 are cleaned up.

[0060] According to the position of the viscous damping wall 400 designed, the sidelines of the lower connecting secondary beam 202 are marked on the lower embedded steel plate 102 on the lower floor. Then, methods such as using a laser plumb bob or a plumb line are used to project the sidelines of the upper connecting secondary beam 201 onto the upper embedded steel plate 101 on the upper floor, and ink lines are snapped and marked with red paint.

[0061] In step S3, the steel wire rope 305 is passed through the reserved hole 105 in the upper-layer floor concrete structural beam. On both sides of the concrete structural beam, a number of wire rope clips 306 are used to make the steel wire rope 305 into a symmetric ring, and the upper part of the hoist 301 is hung in this set of wire rope rings as the lifting force point for hoisting.

[0062] One end of the chain block 302 is connected to the hook 303. There is an upper lifting hole 207 on the middle stiffening rib 205 of the upper connecting secondary beam 201. After the shackle 304 passes through the upper lifting hole 207, it is connected to the hook 303.

[0063] Similarly, there is a lower lifting hole 208 on the middle lower stiffening rib 206 of the lower connecting secondary beam 202; subsequently, the lower lifting hole 208 is connected to the hook 303.

[0064] After the two groups of hoists 301 are connected to the upper connecting secondary beam 201 through the hook 303 and the shackle 304, the chain block 302 is pulled forward simultaneously, and the upper connecting secondary beam 201 is slowly lifted until the upper surface of the upper stiffening edge rib 203 of the upper connecting secondary beam 201 is close to the bottom surface of the upper embedded steel plate 101. After aligning the sidelines of the upper connecting secondary beam 201 and leveling, the top of the upper connecting secondary beam 201 is welded firmly to the periphery of the upper embedded steel plate 101.

[0065] In step S4, after the upper connecting secondary beam 201 is installed in place, the shackle 304 is removed, and the chain block 302 is pulled backward. In a manner similar to step 3, the lower connecting secondary beam 202 is installed, and the bottom of the lower connecting secondary beam 202 is welded firmly to the periphery of the lower embedded steel plate 102; when the lower surface of the lower stiffening edge rib 204 of the lower connecting secondary beam is close to the upper surface of the lower embedded steel plate 102; after aligning the sidelines and determining the position, the lower embedded steel plate and the lower connecting secondary beam are welded.

[0066] In step S5, a temporary lifting point 404 is welded at the center of the outer steel box 401 outside the viscous damping wall 400. The temporary lifting point 404 of the damping wall is made of a steel plate with a lifting hole in the center. The inner steel plate 402 is inserted into the outer steel box 401 in the center and temporarily spot-welded in place, so that the whole viscous damping wall 400 can be installed in place.

[0067] After the lower connecting sub-beam 202 is installed in place, the position sidelines of the outer steel box 401 are marked on the top plate of the lower connecting sub-beam 202, and the position sidelines of the inner steel plate 402 are marked on the bottom plate of the upper connecting sub-beam 201. The shackle 304 is removed, the chain block 302 is pulled in the reverse direction, and according to step 3, the inner steel plate 402 is hoisted and installed by aligning with the position sidelines, so that the top surface of the inner steel plate 402 of the viscous damping wall 400 is fillet-welded around the bottom plate of the upper connecting sub-beam 201.

[0068] The temporary welding points connecting the inner steel plate 402 and the outer steel box 401 are cut off. The chain block 302 is pulled in the reverse direction, and the outer steel box 401 is aligned with the position sidelines, so that the bottom of the outer steel box 401 is close to the top of the lower connecting sub-beam 202, and the bottom of the outer steel box 401 is fillet-welded around the top plate of the lower connecting sub-beam 202.

[0069] After the viscous damping wall 400 is installed in place, the temporary lifting point 404 is cut off, the hoist 301 and the steel wire rope 305 are removed, and the viscous damping material 403 is injected between the outer steel box 401 and the inner steel plate 402 to complete the installation of the viscous damping wall 400.

[0070] Through the above operations, the inner steel plate can be fixed first and then the outer steel box can be fixed, so that the lifting device can hoist the inner steel plate 402 and the outer steel box 401 at the same time, reducing the trouble of subsequent distributed hoisting and being beneficial to improving the construction efficiency.

[0071] Compared with the prior art, the present invention has the following advantages: The installation construction method of a viscous damping wall 400 of the present invention can effectively solve the installation construction problems of the viscous damping wall 400 in the floor, greatly improve the installation accuracy, ensure the construction safety of the operators at the same time, and is economical, reasonable, fast and efficient, with strong practicability and good application prospects.

[0072] Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
