Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a curtain wall construction method. Background Technology

[0002] Super high-rise buildings often employ external tower cranes to meet on-site vertical transportation needs. These external tower cranes are installed from the start of the foundation structure construction and continue until the building's interior decoration and finishing stages. To improve the stability and rigidity of the tower crane, and to accommodate the need for adding sections and raising the tower, several attachment devices are installed throughout the entire height of the tower.

[0003] The attachment members, tied to the tower's frame columns or beams, create a "zipper-like" closure in the exterior curtain wall, significantly extending the overall construction period of the super high-rise curtain wall project. Furthermore, the presence of this zipper-like closure prevents the standard floors of the tower from achieving a fully enclosed facade to prevent rainwater intrusion, severely impacting the concurrent construction of interior finishing work.

[0004] Therefore, how to avoid creating a "zipper-like" gap in the curtain wall from bottom to top due to wall attachment has become an urgent problem to be solved in this field. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to overcome the shortcomings of the prior art and provide a curtain wall construction method.

[0006] This invention provides the following technical solution: a curtain wall construction method, comprising:

[0007] Based on the relationship between the building height and the building plan, determine the tower crane height and the number of wall attachments;

[0008] Based on the arrangement of the curtain wall keel on the building facade, determine the positioning points of the wall attachments and optimize the number of wall attachments to avoid the horizontal keels of the curtain wall.

[0009] Based on the planar positioning of the wall attachment, optimize the positioning point of the wall attachment to avoid the vertical keel of the curtain wall;

[0010] By overlaying and analyzing the wall-mounted support plan, the location of each wall-mounted support is optimized to ensure that the wall-mounted support does not collide with the vertical keel of the curtain wall.

[0011] Detail the production schedule, obtain the unit frame of the curtain wall corresponding to the wall-mounted support arm, and pass the wall-mounted support arm through the unit frame to complete the installation of the curtain wall unit frame at the wall-mounted part.

[0012] Furthermore, the plan layout of the wall-mounted support arm and the wall-mounted positioning diagram are overlaid and analyzed to optimize the climbing scaffold structure.

[0013] Furthermore, during the detailed production scheduling, the unit frames of the curtain wall corresponding to the wall-mounted support arm are obtained based on the wall-mounted support arm layout plan, and the unit frames are marked.

[0014] Further, the curtain wall unit frame is hoisted to the building's preset position, and the horizontal keel corresponding to the curtain wall unit frame is removed;

[0015] The unit frame is passed through the wall-mounted support arm and installed in the corresponding position on the building.

[0016] Furthermore, the removed horizontal keel is installed at the bottom of the unit frame at the lower part of the wall-mounted support arm, and the horizontal keel is connected to the building so that the horizontal keel is restored to its initial installation position on the unit frame.

[0017] Furthermore, the wall attachment includes a wall attachment arm and embedded parts;

[0018] The embedded parts are pre-embedded at the positioning points, and the climbing scaffold is connected to the embedded parts through the wall-mounted support arms.

[0019] Furthermore, the distance between two adjacent attached walls is h, and the value of h is in the range of 15m≤h≤24m.

[0020] Furthermore, by using BIM software to simulate and analyze the collision relationship between the wall attachment and the curtain wall unit frame during the wall attachment removal process, the wall attachment support was fixed and operated by setting up a wall attachment support frame inside the floor and suspending an electric hoist to stabilize the wall attachment support.

[0021] Furthermore, an operating platform frame is erected at the bottom of the wall-mounted support arm to support the wall-mounted support arm.

[0022] Electric hoists are installed inside the building floors to secure the wall-mounted outriggers, while tower crane hooks are used to secure the wall-mounted outriggers outside the building.

[0023] Furthermore, the wall-mounted support arm is removed from the embedded parts and then removed from the climbing scaffold.

[0024] Retract the electric hoist chain and use the tower crane hook to lift the wall-mounted boom and tilt it upwards to effectively avoid the unit frame;

[0025] The tower crane's boom is hoisted outwards to attach the wall-mounted support arm to complete the dismantling of the wall-mounted support.

[0026] The embodiments of the present invention have the following advantages: by meticulously arranging the wall-mounted installation positioning, decomposing and installing the curtain wall unit frame of the wall-mounted support arm in stages, and taking meticulous measures to ensure the safe dismantling and construction of the wall-mounted support, the zipper opening of the exterior curtain wall can be installed ahead of time, and the water is completely sealed off to create a dry working environment for interior decoration. The construction of the overall decoration and renovation sub-project is accelerated and efficient, and the construction cycle is shortened.

[0035] like Figure 1 As shown, some embodiments of the present invention provide a curtain wall construction method, which is mainly applied to the construction of high-rise buildings to form a closed facade, realize the interleaved construction of the exterior and interior of the building, shorten the overall construction period of high-rise curtain wall projects, and improve construction efficiency.

[0036] The curtain wall construction methods include:

[0037] Step S100: Determine the tower crane height and the number of wall attachments based on the relationship diagram between the building height and the building plan position.

[0038] Specifically, the height of the building and its planar position are obtained, and the height of the building and its overall frame are simulated through BIM modeling. The height of the tower crane is determined based on the height of the building, and the number of attached walls is determined based on the planar position of the building.

[0039] Among them, the wall-mounted bracket is a wall-mounted tie-down component added to the tower crane during high-rise construction to prevent lateral shear damage.

[0040] It should be noted that the difference between the height of the tower crane and the height of the building should be greater than or equal to 10m. This is to ensure that the hoisted load does not hit the building or the construction workers on the building, so that the building materials can be safely hoisted to the building floor.

[0041] In addition, the distance between adjacent attached walls is h, where the value of h ranges from 15m to 24m. The specific number of attached walls can be calculated based on the building height. It can be understood that the range of h includes any of the following: 15m ≤ h ≤ 24m, 16m ≤ h ≤ 24m, 17m ≤ h ≤ 24m, 18m ≤ h ≤ 24m, 19m ≤ h ≤ 24m, 20m ≤ h ≤ 24m, 21m ≤ h ≤ 24m, 22m ≤ h ≤ 24m, and 23m ≤ h ≤ 24m, and can be specifically set according to the actual situation.

[0042] For example, when h is 15m and the building height is 160m, the number of attached walls is 10. When h is 24 and the building height is 160m, the number of attached walls is 6. The specific calculation method for the number of attached walls is to take the integer part of the ratio between the building height and h as the number of attached walls.

[0043] Step S200: Based on the arrangement of the curtain wall keel on the building facade, determine the positioning points of the wall attachments and optimize the number of wall attachments to avoid the horizontal keels of the curtain wall.

[0044] Among them, curtain wall keel refers to the horizontal and vertical keels of the curtain wall. In addition, building curtain wall refers to the non-load-bearing exterior wall cladding of a building, which is usually composed of panels (glass, metal panels, stone panels, ceramic panels, etc.) and the supporting structure behind them (aluminum beams and columns, steel structure, glass ribs, etc.).

[0045] Specifically, the positioning points of the wall attachments are determined based on the arrangement of the horizontal joists of the building's exterior curtain wall. These positioning points refer to the locations of the wall attachments on the building. In other words, the corresponding positions of the wall attachments on the building are determined by the arrangement of the horizontal joists, the number of wall attachments, and the distance between adjacent wall attachments. This ensures that each wall attachment avoids the horizontal joists of the curtain wall, thereby guaranteeing installation and construction efficiency.

[0046] The optimization of the number of wall attachments mentioned here refers to, based on the number of wall attachments determined in step S100, and in conjunction with the arrangement of the horizontal keels in the curtain wall, simulating the positional relationship between each group of wall attachments and the horizontal keels in the BIM model, and adjusting the positions of wall attachments that overlap or partially overlap with the horizontal keels so that the wall attachments avoid the horizontal keels. Since the spacing between the wall attachment and the two adjacent wall attachments changes when adjusting the position of the wall attachment that overlaps or partially overlaps with the horizontal keels, the position can be adjusted accordingly based on the preset distance range between two adjacent wall attachments. During the adjustment process, one wall attachment may be added or removed, thereby optimizing the number of wall attachments.

[0047] It should be noted that, since the building has multiple floors, when calculating the number of attached walls based on the distance between adjacent attached walls, there may be attached walls between the horizontal and vertical keels of the building's exterior curtain wall. This may result in the attached walls overlapping or interfering with the horizontal or vertical keels.

[0048] Based on the above issues, in this embodiment, the distance between two adjacent wall attachments can be specifically set according to the actual situation. That is to say, the distance between two adjacent wall attachments is not necessarily equal. The specific position of the wall attachment can be set according to the arrangement and relationship between the horizontal and vertical keels of the actual curtain wall, so that the wall attachment can avoid the horizontal and vertical keels during the installation process, thereby ensuring the stability of the connection between the wall attachment and the building, avoiding the conflict between the position of the wall attachment and the position of the keel, avoiding the need for rework or redesign of the wall attachment, and thus effectively improving construction efficiency.

[0049] Step S300: Optimize the positioning point of the wall attachment according to the planar positioning of the wall attachment to avoid the vertical keel of the curtain wall.

[0050] The planar positioning based on the wall attachment mentioned here refers to observing the positional relationship between the wall attachment and the vertical keel of the curtain wall in the vertical direction.

[0051] Specifically, the BIM modeling simulates the positional relationship between the wall-mounted structures and the vertical keel of the curtain wall after optimization in step S200. Since step S200 optimizes the number of wall-mounted structures and the distance between adjacent tower cranes, the wall-mounted structures can completely avoid the horizontal keel. However, the vertical keel of the curtain wall may overlap or partially overlap with the wall-mounted structures, resulting in the wall-mounted structures not being able to connect with the building.

[0052] Based on the above problems, in step S300, the positioning points between the wall attachment and the building are adjusted in the BIM model drawing in conjunction with the planar positioning of the vertical keel, that is, the positioning points of the wall attachment are optimized so that the wall attachment avoids the vertical keel of the curtain wall.

[0053] It should be noted that optimizing the positioning point of the wall attachment refers to moving the wall attachment horizontally (moving it in the horizontal direction, i.e., parallel to the horizontal keel) to the positioning point of the wall attachment on the building so that the wall attachment can avoid the vertical keel. This allows the wall attachment to avoid both the vertical and horizontal keels, thus ensuring the stability of the connection between the wall attachment and the building, while preventing the wall attachment from affecting the horizontal and vertical keels of the curtain wall, thereby ensuring the integrity of the curtain wall.

[0054] Step S400: Using the wall attachment plan, perform overlay analysis on the positioning of each wall attachment, optimize the wall attachment position and the climbing frame, and ensure that the wall attachment does not collide with the vertical keel of the curtain wall.

[0055] It should be noted that the wall attachment is installed between the climbing scaffold and the building to limit and fix the climbing scaffold and the building, thereby improving the stability between the climbing scaffold and the building.

[0056] Specifically, in the BIM modeling drawings, the plan layout is observed in the vertical direction to obtain the positional relationship between each wall-mounted support arm and the vertical keel. The positions of the wall-mounted supports and the climbing scaffold are optimized according to the actual situation to avoid collisions between the wall-mounted supports and the vertical keel of the curtain wall.

[0057] It should be noted that the wall attachment includes the wall attachment arm, which connects the building to the climbing scaffold. During the lateral movement of the wall attachment arm, there may be a gap between the wall attachment arm and the building. In other words, when the end of the wall attachment arm close to the building moves parallel to the horizontal keel, the wall attachment arm may be unable to connect with the building. Although the wall attachment arm can avoid the vertical keel at this time, it cannot provide support and fixation for the climbing scaffold.

[0058] Based on the above problems, in step S400, by moving the climbing scaffold frame, that is, moving the climbing scaffold frame closer to the building or moving the climbing scaffold frame away from the building, the wall-mounted support arm avoids the vertical keel. This can ensure that the positioning point of the wall-mounted support arm and the building remains unchanged, and can also form a connection and fixation between the building and the climbing scaffold frame.

[0059] Step S500: Deepen production scheduling, obtain the unit frame of the curtain wall corresponding to the wall-mounted support arm, and pass the wall-mounted support arm through the unit frame to complete the installation of the unit frame of the corresponding part of the wall-mounted support.

[0060] Specifically, the curtain wall includes multiple unit frames. The unit frames that need to be passed through by the wall-mounted support arms are identified and numbered. When installing the unit frames, the bottom horizontal keel of the unit frame is first removed so that the unit frame can avoid the wall-mounted support arms. After the unit frame passes through the wall-mounted support arms, the horizontal keel that was removed from the unit frame is installed at the bottom of the unit frame to restore the unit frame to its original state. This allows the unit frame to pass through the fixed wall-mounted support arms, thus completing the installation of the unit frame.

[0061] It is understandable that by performing the "disassembly" and "assembly" of the unit frame in stages, the wall-mounted support arm can pass through the unit frame while the unit frame is being installed, thus ensuring the integrity of the unit frame.

[0062] In some embodiments of the present invention, the plan layout of the wall-mounted support arm and the wall-mounted positioning diagram are overlaid and analyzed to obtain the positional relationship between the wall-mounted support arm and the vertical keel, so as to determine whether there is an overlapping or partial overlapping area between the wall-mounted support arm and the vertical keel, so as to optimize the climbing scaffold.

[0063] It should be noted that when there is overlap or partial overlap between the wall-mounted support and the vertical keel, the positional relationship between the wall-mounted support and the vertical keel can be adjusted by moving the distance between the climbing scaffold and the building. This allows the wall-mounted support to avoid the vertical keel, ensuring the stability of the connection between the wall-mounted support and the building, while also ensuring the integrity of the vertical keel between the wall-mounted support and the curtain wall. This allows for large-area enclosure of the building's exterior facade and effectively prevents rainwater from entering and seeping into the floors, providing effective protection for finished products against external water pollution during interior decoration construction.

[0064] In some embodiments of the present invention, during detailed production planning, the unit frame of the curtain wall corresponding to the wall-mounted support arm is obtained according to the plan layout diagram of the wall-mounted support arm. The unit frame of the curtain wall corresponding to the wall-mounted support arm refers to the unit frame of the curtain wall through which the wall-mounted support arm needs to pass. By marking the unit frame, the horizontal keel corresponding to the unit frame of the curtain wall can be removed during the construction process.

[0065] Specifically, the unit frame is lifted by a winch hook and hoisted to the preset position on the building for installation. Then, the curtain wall installation workers remove the horizontal keel at the bottom of the unit frame on the corresponding floor of the building. The unit frame with the bottom horizontal keel removed is then lowered so that it passes through the wall-mounted support arm at the corresponding position. At the same time, the unit frame is installed in the corresponding position on the building.

[0066] In addition, the removed horizontal keel is installed at the bottom of the unit frame at the lower part of the wall-mounted support arm, and the horizontal keel is connected to the building so that the horizontal keel is restored to its initial installation position on the unit frame, and the unit frame is calibrated and aligned to complete the installation of the unit frame.

[0067] By breaking down the curtain wall unit frames and installing them step by step through the wall-mounted supports, construction efficiency is improved while ensuring the integrity of the wall-mounted supports and unit frames.

[0068] In some embodiments of the present invention, the wall attachment includes a wall attachment arm and an embedded part.

[0069] Specifically, in this embodiment, each of the attached walls has three attached arms, which are connected to the building to form a triangular structure to improve the stability of the connection between the climbing scaffold and the building.

[0070] It should be noted that the pre-embedded parts are embedded in the positioning points on the load-bearing columns of the building, and the climbing formwork is connected to the pre-embedded parts through the wall-mounted support arms.

[0071] In some embodiments of the present invention, the collision relationship between the wall attachment and the curtain wall unit frame during the wall attachment removal process is simulated and analyzed using BIM software. By setting up a wall attachment support fixed operation frame inside the floor and suspending an electric hoist to stabilize the wall attachment support, the wall attachment support is prevented from shaking and damaging the installed curtain wall unit frame and the glass panels in the unit frame during dismantling. The wall attachment at the zipper opening of the curtain wall is removed in a refined manner.

[0072] Specifically, an operating platform frame is erected at the bottom of the wall-mounted arm. The operating platform frame supports the wall-mounted arm to improve its stability during disassembly, prevent one end of the wall-mounted arm from swaying and affecting the unit frame of the curtain wall, thereby enabling safe disassembly operations.

[0073] The system involves installing electric hoists inside the building floors to stabilize the wall-mounted support arms, and using tower crane hooks to stabilize the support arms outside the building to ensure their stability.

[0074] Next, loosen the pin shaft between the wall-mounted support arm and the embedded part, remove the wall-mounted support arm from the embedded part, and have the wall-mounted support arm stabilized by the staff located in the corresponding position inside the building. Loosen the pin shaft between the tower crane boom and the climbing scaffold to remove the wall-mounted support arm from the climbing scaffold. Retract the electric hoist chain, lift the wall-mounted support arm upwards and tilt it to effectively avoid the unit frame by using the tower crane hook, and have the wall-mounted support arm stabilized by the staff to prevent it from swaying and colliding with the glass in the curtain wall unit frame. Hoist the tower crane boom outwards to install the wall-mounted support arm to complete the dismantling of the wall-mounted support.

[0075] This invention enables the pre-installation of the zipper opening of the exterior curtain wall by employing measures such as meticulously arranging the positioning of the wall-mounted installation, disassembling and installing the curtain wall unit frame of the wall-mounted support arm in stages, and taking meticulous measures to ensure the safe disassembly and construction of the wall-mounted installation.

[0076] It should be noted that in this invention, the tower crane model is the externally attached STC7020P tower crane, and the exterior curtain wall adopts a unitized glass curtain wall system.
