Description

Technical Field

[0001] This utility model belongs to the field of ceiling installation for connecting corridors, and particularly relates to an anti-deformation rod for the overall hoisting of ceiling curtain walls in high-altitude connecting corridors. Background Technology

[0002] With my country's modernization and the rapid development of the construction industry, innovative building curtain wall designs have brought new challenges to curtain wall construction. Construction workers, with extensive experience in the design and construction of high-rise connecting corridors, are increasingly paying attention to technical issues that arise during construction, and the construction of ceilings for high-rise connecting corridors is one such challenge. Traditional construction of ceilings for high-rise steel structure connecting corridors uses track-mounted suspended platforms or full-span scaffolding as construction platforms, employing conventional procedures: first, the keel is installed, then the aluminum panels are installed. Because this is high-altitude work, and given the large area of ​​the ceiling structure, it is prone to deformation during hoisting, resulting in poor installation quality after the ceiling structure is in place, making it difficult to guarantee the final installation quality. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an anti-deformation rod for the overall hoisting of the ceiling curtain wall of a high-altitude corridor, so as to solve the technical problem in the prior art that the large area of ​​the ceiling structure is prone to deformation during the hoisting process, resulting in poor installation quality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model for an anti-deformation rod used for the overall hoisting of a high-altitude connecting corridor ceiling curtain wall is as follows:

[0005] A type of anti-deformation rod for integral hoisting of ceiling curtain wall in high-altitude corridors.

[0006] It includes the anti-deformation rod body and the connecting rod fixed below the anti-deformation rod body;

[0007] The anti-deformation rod body is used to be installed above the ceiling frame, and the anti-deformation rod body is perpendicular to the main keel of the ceiling frame; the connecting rod is detachably connected to the main keel.

[0008] The anti-deformation rod is fixed with a hanging steel plate, and the hanging steel plate has a long hole for connecting with the lifting device.

[0009] Beneficial effects: The anti-deformation rod of this utility model can increase the structural strength of the ceiling frame. The anti-deformation rod is directly hoisted by the lifting device, thereby indirectly hoisting the ceiling frame. During the hoisting process, the anti-deformation rod reinforces and supports the ceiling frame, which can maximize the structural stability of the ceiling frame and ensure the connection accuracy of the ceiling frame. That is, the ceiling frame can maintain a high connection accuracy before hoisting and after hoisting, thus ensuring the construction quality of the ceiling curtain wall of the high-altitude corridor.

[0010] Furthermore, the lifting device includes a bracket for detachably mounting on the floor slab and a lifting component fixed on the bracket. The floor slab is provided with a lifting hole, and the lifting component extends downward from the lifting hole to below the floor slab. Multiple lifting devices are correspondingly provided on the floor slab, and the lifting components of the multiple lifting devices operate synchronously.

[0011] Beneficial effects: The lifting device has a simple structure, strong stability when installed on the floor, and can withstand large loads.

[0012] Furthermore, four reinforcing ribs are welded between the hanging steel plate and the anti-deformation rod body.

[0013] Beneficial effects: The addition of reinforcing ribs increases the connection strength between the hanging steel plate and the anti-deformation rod.

[0014] The support is a cuboid support with its bottom fixed to the floor slab. A suspension beam is installed in the middle of the top of the support, and an "Ω"-shaped hanger is fixed below the suspension beam. The hanger is fixed to the hanger.

[0015] Beneficial effects: The rectangular support structure increases the structural stability of the support. When the hanging components lift the ceiling frame through the anti-deformation rod, the hanging components apply a downward force to the rectangular support, enabling the rectangular support to be stably supported on the floor slab.

[0016] The lifting device is an electric chain hoist.

[0017] Beneficial effects: The installation of the lifting components is simple and facilitates centralized control of the lifting components.

[0018] The anti-deformation rod corresponds to two lifting devices, which are installed at both ends of the anti-deformation rod, and the hanging steel plate is fixed to both ends of the anti-deformation rod body.

[0019] Beneficial effect: The anti-deformation rod is lifted by two lifting devices, which ensures the hoisting stability of the anti-deformation rod.

[0020] Several sets of connecting rods for connecting to the main keel of the ceiling frame are correspondingly provided below the anti-deformation rod body.

[0021] Beneficial effects: The anti-deformation rod is connected to the main keel of the ceiling frame through several sets of connecting rods, which increases the number of connections between the anti-deformation rod and the ceiling frame. When the ceiling frame is lifted, the anti-deformation rod can play a role in strengthening and protecting the ceiling frame, preventing deformation of the ceiling frame during lifting, which would affect the installation accuracy of the ceiling frame.

[0030] The following is a more detailed description of an anti-deformation rod for the overall hoisting of a high-altitude connecting corridor ceiling curtain wall, in conjunction with the accompanying drawings and specific embodiments:

[0031] The honeycomb aluminum panel ceiling of this utility model, which is hoisted as a whole for the high-altitude connecting corridor, has an area of ​​1200m² and an elevation of 48.7m. The processing area below the ceiling consists of 6-layer and 7-layer structural slabs with elevations of 21.8m and 25.9m respectively. Based on the different elevations of the floor slab processing area, the ceiling is divided into two sections, east and west. The honeycomb aluminum panel area of ​​the west section is approximately 600 square meters, and the area of ​​the east section is approximately 650 square meters. The two sections can be constructed in a continuous flow to ensure construction efficiency.

[0032] The anti-deformation rod includes an anti-deformation rod body and a connecting rod fixed below the anti-deformation rod body. The anti-deformation rod body is set above the ceiling frame and is perpendicular to the main keel of the ceiling frame. In this embodiment, the anti-deformation rod body is a rectangular steel pipe.

[0033] The connecting rods on the anti-deformation rod body are detachably connected to the main keel. In this embodiment, each anti-deformation rod body has several sets of connecting rods connected to the ceiling frame below it. That is, each anti-deformation rod body can span several main keels. The anti-deformation rod body is fixedly connected to the main keel through the connecting rods. When the anti-deformation rod is lifted by the hanger, it can be connected to several main keels at the same time. When the hanger lifts the anti-deformation rod, the anti-deformation rod can simultaneously drive the main keels of several ceiling frames to be lifted, ensuring the synchronicity of the main keels connected to the anti-deformation rod during lifting.

[0034] In this embodiment, each anti-deformation rod corresponds to two lifting devices, which are located at both ends of the anti-deformation rod. Hanging steel plates are fixed to both ends of the anti-deformation rod body, and the hanging steel plates have elongated holes for connection with lifting components; in this embodiment, the hanging steel plates are fixed above the anti-deformation rod body.

[0035] To increase the structural strength between the hanging steel plate and the anti-deformation rod, in this embodiment, four reinforcing ribs are welded between the hanging steel plate and the anti-deformation rod.

[0036] The lifting device includes a bracket detachably mounted on the floor slab and a lifting component fixed on the bracket. The floor slab is provided with lifting holes, and the lifting component extends downward from the lifting holes to below the floor slab. Multiple lifting devices are provided on the floor slab corresponding to the lifting holes. The lifting components of the multiple lifting devices work synchronously to enable the lifting devices to lift the ceiling frame synchronously.

[0037] Specifically, the support frame is a rectangular frame, with its bottom fixed to the floor slab. A suspension beam is installed in the middle of the top of the support frame, and an "Ω"-shaped hanger is fixed below the suspension beam. The lifting device is fixed to the hanger. In this embodiment, the lifting device is an electric chain hoist.

[0038] The overall hoisting and installation process of the ceiling curtain wall of the high-altitude connecting corridor includes the following steps:

[0039] S1: Pre-embedded lifting holes in the floor slab; the positions of the lifting holes are determined before the floor slab construction. During the installation of the floor decking, round pipes are used in conjunction with the coordinates of the lifting points of the unit panels to set the pre-embedded pipes. Then, concrete is poured to form the floor slab, and the round pipes and pre-embedded pipes form lifting holes on the floor slab. In this embodiment, the internal diameter of the lifting hole is 76mm. The lower end of the pre-embedded pipe is fixed to the floor decking by welding, and the upper end is reinforced by connecting it to the main reinforcement with 8mm diameter round steel to prevent the concrete from being misaligned during vibration. After the pre-embedded pipe is installed, it is inspected and then concrete is poured. In this embodiment, the lifting holes are arranged on both sides of the main steel beam 5 of the floor slab, and several lifting holes on each side are arranged at intervals in the extension direction of the main steel beam 5 of the floor slab; secondary steel beams 7 are fixedly installed between the main steel beams 5 of the floor slab.

[0040] S2: Install lifting devices; including brackets 18 detachably mounted on the floor slab with corresponding lifting holes and lifting components fixed on the brackets 18, with the lifting components extending downward from the lifting holes to below the floor slab; multiple lifting devices are correspondingly installed on the floor slab, and the lifting components of the multiple lifting devices operate synchronously.

[0041] In this embodiment, the support 18 is a cuboid support. The support 18 is a cuboid support with a length and width of 1000mm and a height of 1500mm, made of 80×80×4mm square steel pipe. An 80×80×4mm square steel pipe suspension beam is set in the middle of the top of the support 18, and an "Ω"-shaped hanger 19 is fixed below the suspension beam. The bottom of the support 18 is fixed to the floor slab. Specifically, the bottom of the support 18 is welded to a 300×400×8mm hot-dip galvanized steel plate and fixed to the floor slab with chemical anchors. The hanging parts are fixed on the hanger 19. In order to ensure the stability of the ceiling lifting and prevent the lifting point from shifting, a DHP electric chain hoist 22 is selected. The chain has a diameter of 10mm and a length of 60m. The electric chain hoist 22 is suspended on the support 18 and fixed firmly. The chain passes through the lifting hole 6 and hangs down to the ceiling processing position below.

[0042] A synchronous control system is installed on each lifting device's lifting component. This system includes a controller, weight sensors connected to the controller, an external display connected to the controller, and a wireless remote controller. The weight sensors are mounted on the lifting components, and a single-point load tension value under normal operating conditions is set on each sensor. The external display shows the force data during lifting. If the set tension is exceeded, the weight sensor will alarm and cut off power after the external display shows the increased tension. Then, the wireless remote controller will lift or lower components with uneven stress to maintain the entire system in a balanced state, preventing uneven stress and overall overturning during the lifting process. In this embodiment, the single-point load tension value under normal operating conditions is 21kN, and each electric chain hoist 22 has a power of 500W.

[0043] S3: Ceiling fabrication and processing;

[0044] (1) Ceiling frame welding. The ceiling frame includes a main keel 11 and a secondary keel 12 welded perpendicularly to the main keel 11. Ceiling connectors 9 are fixed at intervals in the extension direction of the main keel 11. One end of the ceiling connector 9 is fixedly connected to the main keel 11, and the other end of the ceiling connector 9 is used to be fixedly connected to the floor slab.

[0045] The main keel 11 includes several spliced ​​connecting segments, with adjacent connecting segments fixedly connected by a first insert. The secondary keel 12 is fixedly connected to the main keel 11 by a second insert. Both the first and second inserts are "D" shaped inserts. In this embodiment, the direction of the ceiling main keel 11 is the same as the extension direction of the secondary steel beam of the floor slab. The main keel 11 is 26.6m long. According to the layout dimensions, the 160×80×4mm main keels 11 are spliced ​​together. The joints are connected internally by a custom-made 140×60×6mm first insert, which is "D" shaped. After one end of the first insert is fully welded to the connecting segment, it is inserted into the connecting segment of another main keel 11, with a length of not less than 200mm.

[0046] The secondary keel 12 is made of 120×60×4mm hot-dip galvanized square steel pipe. The secondary keel 12 and the main keel 11 are connected by a 70mm long 102×42×5mm second insert. The second insert is a "D" shaped insert. One end of the second insert is welded to the secondary keel 12, and the other end of the second insert is welded to the main keel 11.

[0047] The ceiling connector 9 is made of 12# hot-dip galvanized channel steel and is connected to the main keel 11 by two M12×130 stainless steel bolts, with a 2mm thick flexible pad in the middle.

[0048] Before welding the ceiling frame, a total station is used to measure the main steel structure of the ceiling, BIM technology is used to create a model, and then the data is extracted. Directly below the installation position of the ceiling frame, a laser plumb line is used to project and mark the ceiling processing data on the processing area. The accuracy of the reference points is then re-measured using a total station. For minor deviations between reference points, the equal-offset centering method is used to eliminate errors.

[0049] During the welding of the ceiling frame, a blank support is used to support the ceiling frame. A jig is fabricated on-site using 160×80mm hot-dip galvanized square steel, with a grid size of 3000×4200mm and an overall size of 25000×27000mm. When installing the panel 10, the ceiling frame is lifted off the blank support to facilitate the installation of the panel and the ceiling frame. In this embodiment, the blank support includes a grid-like support frame and legs fixed below the grid-like support frame.

[0050] (2) Installation of anti-deformation rod: The anti-deformation rod 23 includes an anti-deformation rod body and a connecting rod 20 fixed below the anti-deformation rod body. The anti-deformation rod body is set above the ceiling frame and is perpendicular to the main keel 11 of the ceiling frame. The connecting rod 20 is detachably connected to the main keel 11. Hanging steel plates 21 are fixed at both ends of the anti-deformation rod body. The hanging steel plates 21 have elongated holes for connecting with the hanging parts. In this embodiment, the elongated holes on the hanging steel plates 21 are φ30mm. Each hanging steel plate 21 is welded with 4 reinforcing ribs with a thickness of 5mm.

[0051] In this embodiment, the anti-deformation rods 23 are installed perpendicular to the extension direction of the main keel 11 during hoisting. Each anti-deformation rod 23 is equipped with three or four sets of connecting rods 20. Each set of connecting rods 20 is respectively set with the main keel 11. Each set of connecting rods 20 includes two rods located on both sides of the main keel 11. The connecting rods 20 and the main keel 11 are detachably connected by bolts. Each anti-deformation rod 23 has two electric chain hoists 22 at both ends and two supports on the floor slab. That is, the two electric chain hoists 22 on the two supports 18 hoist one anti-deformation rod 23 at the same time, and the ceiling is lifted by several anti-deformation rods 23.

[0052] Analysis of the skeleton revealed that the secondary keel 12 was located at the corresponding point of the hoisting device. However, the strength of the secondary keel 12 was insufficient to meet the hoisting requirements. Therefore, a 200×200×6mm steel square tube was added as the anti-deformation rod body. In other words, the anti-deformation rod 23 was parallel to the extension direction of the secondary keel 12 and placed at a horizontal and vertical angle with the main ceiling keel 11. The connecting rod 20, which was fixed below the anti-deformation rod body, was made of 12# channel steel. The connecting rod 20 was connected to the main keel 11 using M16×260mm stainless steel bolts. To ensure the welding quality of the connecting rod 20 and the anti-deformation rod body, the galvanized layer within the upper 10mm range of the channel steel was completely ground off.

[0053] (3) Install the supporting steel plate, perform trial hoisting, install the panel. After the anti-deformation rod 23 is installed, the supporting steel plate is laid on the ceiling frame to form a construction platform after lifting. The supporting steel plate is detachably connected to the main keel 11. In this embodiment, the supporting steel plate is a 1.5mm thick YX75-200-600 floor decking. The supporting steel plate is fixed to the main keel 11 with hexagonal screws.

[0054] After the floor slab construction quality is accepted, the hoisting parts are connected to the hanging steel plate 21 of the anti-deformation rod 23 hoisting frame, and the frame is lifted to the floor slab and left to stand still. In this embodiment, the frame needs to be lifted to 1.8 meters above the floor slab and left to stand still for 24 hours.

[0055] The panel is fixed below the ceiling frame, and the flatness of the panel mounting surface is checked. In this embodiment, the panel is a honeycomb aluminum panel. After the ceiling frame is adjusted, the 25mm thick honeycomb aluminum panel is installed. The bottom of the ceiling is 1.8m from the floor slab. The height of the honeycomb aluminum panel fixing bracket is 18mm. A 2mm rubber gasket is placed between the bracket and the ceiling frame, and then the panel is fixed with hexagonal screws. After the honeycomb aluminum panel is installed, the flatness and hook force data are checked again. After confirming that everything is correct, the lifting operation begins. The height of the frame is locally adjusted by the individual control switch of the electric chain hoist 22 to make the ceiling flatness meet the requirements. At this time, the chain pull sensor data is locked, and the synchronous lifting system is started to lift the entire panel at a speed of 9m per hour. First, it is lifted to a height of 1.8m. After the honeycomb aluminum panel is installed, it is lifted to the installation height.

[0056] The panel includes several alternating first panels and second panels. A first fixing bracket is fixed to the side of the first panel facing the second panel and is fixed to the frame. The first fixing bracket is provided with a slot 15 with an opening facing the second ceiling. A rubber layer is pasted in the slot 15. A second fixing bracket is fixed to the side of the second panel facing the first panel and is provided with a plug-in plate that is compatible with the slot of the first fixing bracket. A horizontal plate is provided at the upper end of the second fixing bracket. When the plug-in plate is compatible with the slot, the horizontal plate contacts the bottom of the bracket. An adhesive layer is fixed to the side of the secondary keel facing the bracket.

[0057] S4: Ceiling fixing; After multiple lifting devices work together to lift the entire ceiling to the installation height, the workers enter the construction platform and fix the upper end of the ceiling connector 9 to the secondary steel beam of the floor slab.

[0058] After the ceiling is raised to the installation height, the distance between the floor deck working platform and the top floor slab is about 1.8m. Workers enter the construction platform by climbing ladders and weld the ceiling connector 9 to the secondary steel beam of the floor slab. At this time, the ceiling is not only welded to the secondary steel beam of the floor slab through the connector, but the anti-deformation rod 23 of the ceiling is also connected to the bracket 18 on the floor slab through the electric chain hoist 22.

[0059] S5: Removal of lifting device, anti-deformation hoisting frame, and supporting steel plate;

[0060] When dismantling the lifting device, first disconnect the power to the lifting device, then dismantle the lifting components one by one, and finally remove the bracket 18 from the floor slab. Then, the construction workers enter the construction platform, remove the anti-deformation rod 23 from the frame, and then use a cutting machine to cut the anti-deformation rod 23 hoisting frame into 1m length sections, which are then carried out one by one from the construction platform. After all the construction inside the ceiling is completed, the supporting steel plates of the construction platform are removed one by one. The workers transport them outside the ceiling while dismantling them, and clean up the remaining garbage inside the ceiling.

[0061] S6: Backfilling of lifting holes; After the ceiling is installed, concrete is poured into the lifting holes to seal them.

[0062] After the ceiling is installed, the bottom of the hoisting hole is sealed with a template, and concrete is poured in two stages. The first pour of concrete is half the depth of the hoisting hole. After testing for leaks, waterproof material is applied, and then the remaining concrete is poured to ensure the waterproofness and integrity of the floor slab.

[0063] During the overall hoisting of the ceiling curtain wall of the high-altitude corridor, the overall lifting device is first arranged according to the architectural structure and characteristics of the site, and a hoisting bracket 18 is set at each hoisting point at the reserved hoisting hole position. Next, the overall lifting steel frame is assembled on the 6th and 7th floor structural slabs. The steel frame is welded and processed according to the drawings directly below the construction section, and the ceiling connector 9 and supporting steel plate are pre-installed on the steel frame. Then, an electric chain hoist 22 is installed on the floor slab of the construction section. The hook of the electric chain hoist 22 is passed through the reserved hole and lowered to the ceiling frame for connection and fixation. The frame is then lifted to a height of 1.8m, and then the honeycomb aluminum panel is installed. After the honeycomb aluminum panel is installed, the flatness of the ceiling is measured with a total station. The height of the frame is locally adjusted by the individual control switch of the electric chain hoist 22 to make the flatness of the ceiling meet the requirements. At this time, the data of the chain pull sensor is locked, and the synchronous lifting system is started to lift the whole structure to the installation height at a speed of 9m per hour. After the ceiling was lifted to the installation position, the construction workers entered the space between the ceiling and the 13th floor slab from the 12th floor (elevation 46.4m) and welded the ceiling connector 9 to the secondary steel beam of the floor slab. After the connection, fixing and anti-corrosion and anti-rust construction were completed, the internal auxiliary structure and corrugated steel plate were gradually removed from the middle to both ends.

[0064] The ceiling is lifted at the upper floor slab of the connecting corridor, leaving lifting points and setting up lifting brackets 18. Then, the installed ceiling is lifted using "DHP electric chain hoist 22 synchronous lifting technology". The high-altitude assembly and welding workload is small, the on-site mechanical equipment requirements are low, the high-altitude operation time is short, and the installation efficiency is high.

[0065] The installation of the main horizontal and vertical keels 11 and secondary keels 12, as well as the panel installation and caulking, are all carried out on the ground. The quality of the rectification construction process can be effectively controlled, and the installation efficiency is high. Compared with the traditional high-altitude corridor suspended construction, it reduces the time spent working at height.

[0066] The installation of anti-deformation rods can increase the structural strength of the ceiling frame. The anti-deformation rods are directly hoisted by the lifting device, thereby indirectly hoisting the ceiling frame. This can maximize the structural stability of the ceiling frame and ensure the connection accuracy of the ceiling frame. In other words, the ceiling frame can maintain a high connection accuracy before, during and after hoisting, thus ensuring the construction quality of the ceiling curtain wall of the high-altitude corridor.
