Description

Technical Field

[0001] This invention relates to the field of building structure technology, and in particular to a secondary forming design method for a suspended structure with sequential construction that facilitates the overall lifting of the conversion truss. Background Technology

[0002] The suspended structure system consists of a supporting structure (tube structure, shear wall, frame, etc.), a transfer structure (beams, transfer trusses, arches, cables, etc.), suspended columns (suspenders), and suspended floor slabs. The supporting structure bears all lateral forces and vertical loads. Its core advantages are:

[0003] Spatial flexibility: With no columns below the suspended floors, it can cross obstacles such as rivers, railways, and subways, allowing for flexible building layout;

[0004] Material efficiency: The suspension column (rod) makes full use of the tensile strength of high-strength materials, with small cross-sectional dimensions, reducing self-weight and increasing the usable building area.

[0005] Despite the significant advantages of suspended structure systems, the construction of their core structure—the transfer truss—still faces multiple technical challenges, such as:

[0006] 1) Transfer trusses are generally located on the top floor or middle floors of a building. The structure of transfer trusses is complex, and the high-altitude in-situ assembly construction is difficult. The high-altitude positioning accuracy is difficult to guarantee, which can easily lead to installation deviations.

[0007] 2) High-altitude in-situ welding cannot rotate components like ground operations, resulting in many overhead welding operations, making weld quality control more difficult and flaw detection more challenging.

[0008] 3) The vertical transportation of components, personnel, and equipment for high-altitude construction involves a large volume, low efficiency, and high cost;

[0009] 4) Large temporary supports and platforms need to be erected to meet the requirements of high-altitude assembly and conversion trusses, which increases construction costs and time.

[0010] 5) The support conditions for high-altitude assembly of the conversion truss may not be consistent with the normal usage conditions, requiring separate design, which increases the design workload, design period and material costs.

[0011] In suspended structures where entire floors or large areas of a floor are suspended, multiple transfer trusses positioned at different angles across the core structure are required, creating an enclosure of the transfer trusses on the outer wall of the core. Typically, the transfer trusses rest on the top of the concrete-supported outer wall of the core, and the clear distance of the enclosure is less than the outer edge of the core's outer wall, making it impossible to lift multiple transfer trusses as a whole through the core's outer wall. Lifting them into place from one side of the core requires high-tonnage cranes and specific crane placement, making it difficult to implement. Summary of the Invention

[0012] The purpose of this invention is to provide a secondary forming design method for the cylindrical body of the suspended structure, which facilitates the overall lifting of the transfer truss. The transfer truss is assembled as a whole on the ground, avoiding or significantly reducing high-altitude operations, thereby solving the problems of feasibility, safety and economy in the construction of existing suspended structure transfer trusses.

[0013] To achieve the above objectives, this invention provides a secondary forming design method for a cylindrical structure that facilitates the overall lifting of a transfer truss through a suspended structure construction method. The suspended structure includes a concrete-supported cylindrical body, a transfer truss, suspended columns, and several suspended floor slabs. The outer wall of the concrete-supported cylindrical body is divided in two along its thickness direction, forming an inner layer and an outer layer. The orthographic projection of the transfer truss onto the ground overlaps with the outer layer of the outer wall but not with the inner layer. This secondary forming design method for a cylindrical body that facilitates the overall lifting of the transfer truss through a suspended structure construction method includes:

[0014] First, construct the inner layer of the outer wall of the cylinder;

[0015] The conversion truss is pre-assembled on the ground and lifted as a whole from the outer side of the inner layer of the outer wall of the cylindrical structure to the design elevation;

[0016] A temporary support device is installed on the top of the inner layer of the outer wall of the cylindrical shell, and the transfer truss is placed on the temporary support device. The orthographic projection of the transfer truss on the ground overlaps with the outer layer of the outer wall of the cylindrical shell, but does not overlap with the inner layer of the outer wall of the cylindrical shell.

[0017] Then, the outer layer of the outer wall of the cylinder is constructed, and the outer layer of the outer wall of the cylinder is connected to the inner layer of the outer wall of the cylinder to form an integral concrete support cylinder, and the temporary support device is covered inside the outer layer of the outer wall of the cylinder.

[0018] Hanging columns are installed below the conversion truss, and then the suspended floor slabs are installed layer by layer from top to bottom using the hanging columns. Several of the suspended floor slabs are suspended along the height direction by the hanging columns on the outside of the concrete support cylinder.

[0019] Optionally, the suspended structure sequential construction method for the secondary forming design of the cylinder body that facilitates the overall lifting of the conversion truss also includes an internal floor slab in the cylinder body, which is installed on the inner layer of the outer wall of the cylinder body along the height direction.

[0020] Optionally, the conversion truss can be vertically lifted along the outer side of the inner layer of the outer wall of the cylindrical shell.

[0021] Optionally, the temporary support device is a temporary bracket, and an embedded part is provided in the inner layer of the outer wall of the cylinder, and the temporary bracket is fixedly connected to the embedded part.

[0022] Optionally, the temporary support device is welded or bolted to the embedded part.

[0023] Optionally, the temporary support device is a temporary pillar;

[0024] The inner layer of the outer wall of the cylindrical structure is pre-embedded with cantilever beams, and the temporary supports are fixed to the cantilever beams; or...

[0025] The temporary support was fixed to the ground.

[0026] Optionally, the suspended floor slab includes a main floor beam and a suspended floor slab, and the hanging column is arranged around the suspended floor slab and connected to the concrete support cylinder through the main floor beam.

[0027] Optionally, the inner layer of the outer wall of the cylinder is pre-embedded with reinforcing bars, and the outer layer of the outer wall of the cylinder is reliably connected to the inner layer of the outer wall of the cylinder to form a whole through the reinforcing bars.

[0028] Optionally, the conversion truss is a multi-truss.

[0029] The suspended structure sequential construction method provided by this invention, which facilitates the overall lifting of the transfer truss and the secondary forming design method for the cylinder, has at least one of the following beneficial effects:

[0030] 1) The inner layer of the outer wall of the concrete-supported cylinder and the ground assembly of the transfer truss can be constructed simultaneously, shortening the construction period;

[0031] 2) The multi-section conversion truss is assembled as a whole on the ground, avoiding the risks of high-altitude welding or assembly operations, reducing construction difficulty, and improving assembly quality;

[0032] 3) Ground inspection of the conversion truss reduces the difficulty of inspecting the steel structure;

[0033] 3) The ground assembly of the conversion truss eliminates the need for supports and construction platforms, reducing the design workload and time required for construction simulation, and lowering construction costs;

[0034] 4) The secondary molding of the cylinder ensures the overall lifting of the conversion truss, eliminating a large amount of vertical transportation of components, personnel and equipment, and reducing the construction cost of the suspension structure. Attached Figure Description

[0051] Please refer to Figures 1-8This embodiment provides a secondary forming design method for a cylindrical structure that facilitates the overall lifting of the transfer truss through a suspended structure construction method. The suspended structure includes a concrete-supported cylindrical body 1, a transfer truss 2, a hanger 3, and several suspended floor slabs 4. The outer wall of the concrete-supported cylindrical body 1 is divided into two parts in the thickness direction: an inner layer 11 and an outer layer 12. The orthographic projection of the transfer truss 2 on the ground overlaps with the outer layer 12 but not with the inner layer 11. The secondary forming design method for a cylindrical body that facilitates the overall lifting of the transfer truss through a suspended structure construction method includes:

[0052] S1. First construct the inner layer 11 of the outer wall of the cylinder;

[0053] S2. The conversion truss 2 is pre-assembled on the ground and lifted from the outer side of the inner layer 11 of the outer wall of the cylinder to the design elevation;

[0054] S3. Then install a temporary support device on the outside of the inner layer 11 of the outer wall of the cylinder, and place the transfer truss 2 on the temporary support device. The orthographic projection of the transfer truss 2 on the ground overlaps with the outer layer 12 of the outer wall of the cylinder, but does not overlap with the inner layer 11 of the outer wall of the cylinder.

[0055] S4. The outer wall 12 of the construction cylinder is connected to the inner wall 11 of the outer wall to form an integral concrete support cylinder 1, and the temporary support device is enclosed in the outer wall 12 of the cylinder.

[0056] S5. Install the hanging column 3 below the conversion truss 2, and then use the hanging column 3 to install the suspended floor 4 layer by layer from top to bottom. Several suspended floor 4 are suspended along the height direction by the hanging column 3 on the outside of the concrete support cylinder 1.

[0057] By dividing the traditional concrete support cylinder 1 into an inner cylinder and an outer wall layer for separate construction, the outer wall of the concrete support cylinder 1 is divided in two along its thickness direction. The outer part of the outer wall is called the outer wall layer 12, and the inner part of the outer wall and the shear wall within it are called the inner wall layer 11. The inner wall layer 11 has smaller planar dimensions, which meets the requirement of lifting the transfer truss 2 as a whole outside the inner wall layer 11. After the construction of the inner wall layer 11 is completed, a temporary support device is set up to temporarily support the transfer truss 2, allowing the transfer truss 2 to be assembled on the ground. Then, the outer wall layer 12 is constructed to replace the temporary support device and permanently support the transfer truss 2. The inner and outer walls of the inner cylinder, constructed sequentially, work together to bear the vertical and horizontal loads of the suspended structure. This invention reduces the construction and inspection difficulty of the suspended structure, improves the construction quality of the suspended structure, and reduces the construction cost by adopting a method of secondary construction of the concrete support cylinder 1 and overall lifting of the roof transfer truss 2 from the ground.

[0058] The suspended structure includes a concrete support cylinder 1, a transfer truss 2, hanging columns 3, and several suspended floor slabs 4. The transfer truss 2 is generally placed on top of the concrete support cylinder 1 and includes cantilever trusses 21 and ring trusses 22. The hanging columns 3 are located below the transfer truss 2, and the suspended floor slabs 4 are suspended along the height direction from the outside of the concrete support cylinder 1 via the hanging columns 3. In this embodiment, as shown... Figures 2-6 As shown, taking a suspended cylindrical structure with a 16-story suspended floor as an example, the concrete supporting cylindrical body 1 is 94.5 m high, 19.5 m long, and 16.7 m wide. The main suspension frame uses a transfer truss 2, including a cantilever truss 21 and a ring truss 22. The cantilever truss 21 is located at the top of the concrete supporting cylindrical body 1, with a maximum cantilever length of 10.6 m. The lower chord of the cantilever truss 21 is embedded in the concrete of the concrete supporting cylindrical body 1, and the part of the lower chord outside the concrete supporting cylindrical body 1 serves as a supporting beam for the roof slab. A ring truss 22 is set around the perimeter of the roof, supported by the cantilever truss 21. The structure is suspended 16 stories from the roof. The suspended floor 4 is five to twenty stories high, with a floor height of 4.45m. The structural plan of the suspended floor 4 is 40.5m long and 35.5m wide. The hanging columns 3 include several hanging columns 3 set around the perimeter of the suspended floor 4. The spacing between the hanging columns 3 is 5 to 6.3m. The transfer truss 2 and the suspended floor 4 are made of steel structure, and the hanging columns 3 are made of H-section steel or box-section steel columns.

[0059] In this embodiment, the thickness of the concrete support cylinder 1 is 0.65-1m, and the outer floor slab of the suspended floor 4 has a thickness of 120mm. The transfer truss 2 is made of high-strength steel, the steel beams of the suspended floor 4 are made of Q355 steel, and the hanging column 3 is made of H-section steel.

[0060] In this embodiment, the conversion truss 2 is set on the top of the cylinder. The orthographic projection of the conversion truss 2 on the ground overlaps with the outer layer 12 of the outer wall of the cylinder, but does not overlap with the inner layer 11 of the outer wall of the cylinder. The conversion truss 2 is a truss enclosed by multiple planes, or it can be a truss that does not enclose multiple planes. The present invention does not limit this.

[0061] Optionally, the transfer truss 2 can be placed on the middle floor of the outer wall of the concrete support cylinder 1, dividing the outer wall of the cylinder below the transfer truss into two parts along the thickness direction, designated as the outer layer 12 and the inner layer 11 of the outer wall of the cylinder.

[0062] First, execute S1, constructing the inner layer 11 of the outer wall of the cylinder, which is a concrete structure. In this embodiment, the secondary forming design method of the cylinder, which facilitates the overall lifting of the transfer truss, also includes an inner floor slab 7, which is installed along the height direction on the inner layer 11 of the outer wall. During the construction phase, the inner layer 11 of the outer wall bears the load of its own weight, the inner floor slab 7, the transfer truss 2, and part of the suspended columns 3, while the outer layer 12 of the outer wall bears the load of its own weight, the transfer truss 2, part of the suspended columns 3, and part of the suspended floor slab 4.

[0063] Next, execute S2, pre-assemble the transfer truss 2 as a whole on the ground and lift it from the outer side of the inner layer 11 of the outer wall of the cylinder to the design elevation. The ground assembly can be carried out by directly fabricating and assembling the transfer truss 2 at the ground projection position, or the transfer truss 2 can be fabricated elsewhere and then transported to the ground projection position of the transfer truss 2 for assembly.

[0064] It should be noted that the conversion truss 2 can be pre-assembled on the ground and lifted to the design elevation before installing the temporary support device, or the temporary support device can be installed first, and then the conversion truss 2 can be lifted and placed on the temporary support device. However, considering that installing the temporary support device first may interfere with the vertical lifting of the conversion truss 2, the temporary support device can be designed as a foldable structure. For example, after installing the temporary support device on the inner layer 11 of the outer wall of the cylinder, the temporary support device can be folded and stored, and then the conversion truss 2 can be lifted to the design elevation and the temporary support device can be unfolded to support the conversion truss 2. Since the conversion truss 2 can be constructed and assembled on the ground, a large amount of vertical transportation and the risks of high-altitude operations are eliminated, the construction difficulty is reduced, and the construction and assembly quality is improved.

[0065] In this embodiment, the method adopted is to pre-assemble the transfer truss 2 as a whole on the ground, lift it to a set height, and then install the temporary support device. The hollow dimension of the transfer truss 2 should be larger than the outer diameter of the inner layer 11 of the outer wall of the cylinder, so that the transfer truss 2 can be vertically lifted along the outer side of the inner layer 11 of the outer wall of the cylinder and exceed the bottom end of the inner layer 11 of the outer wall of the cylinder, that is, the size of the inner layer 11 of the outer wall of the cylinder will not affect the vertical lifting of the transfer truss 2.

[0066] Next, execute S3, install a temporary support device on the outer side of the inner layer 11 of the outer wall of the cylinder, and place the transfer truss 2 on the temporary support device. At this time, depending on the strength of the inner layer 11 of the outer wall of the cylinder and the temporary support device, install some of the hanging columns 3 below the transfer truss 2.

[0067] As a preferred embodiment, such as Figures 7-8As shown, the temporary support device is a temporary bracket 51, and an embedded part is provided in the inner layer 11 of the outer wall of the cylinder. The temporary bracket 51 is fixedly connected to the embedded part. Optionally, the temporary bracket 51 is welded or bolted to the embedded part.

[0068] As another preferred embodiment, such as Figures 9-10 As shown, the temporary support device is a temporary column 52; a cantilever beam is pre-embedded in the inner layer 11 of the outer wall of the cylinder, and the temporary column 52 is fixed on the cantilever beam; or, the temporary column 52 is fixed on the ground.

[0069] Then, S4 is executed to construct the outer layer 12 of the outer wall of the cylinder, connecting the outer layer 12 of the outer wall of the cylinder with the inner layer 11 of the outer wall of the cylinder to form an integral concrete support cylinder 1, and the temporary support device is enclosed in the outer layer 12 of the outer wall of the cylinder. That is to say, the temporary support device does not need to be disassembled and can be directly embedded in the later-poured concrete support outer layer 12 of the outer wall of the cylinder, thereby simplifying the construction.

[0070] In this embodiment, the inner layer 11 of the outer wall of the cylinder is pre-embedded with reinforcing bars, and the outer layer 12 of the outer wall of the cylinder is reliably connected to the inner layer 11 of the outer wall of the cylinder through the reinforcing bars to form a whole. The reinforcing bars (also called reserved anchor bars) have one end pre-embedded in the inner layer 11 of the outer wall of the cylinder, and the other end extends outward to form a reinforcing bar, which is used to form a mechanical anchor with the outer layer 12 of the outer wall of the cylinder during the pouring, so that the outer layers of the inner and outer walls of the cylinder, which are constructed separately, are connected into a whole, and the outer layers of the inner and outer walls of the cylinder, which are constructed separately, are transformed into a whole that shares the load.

[0071] Finally, execute S5, continue to install the hanging column 3 below the conversion truss 2, and then use the hanging column 3 to install the suspended floor 4. Several suspended floor 4 are suspended along the height direction by the hanging column 3 on the outside of the concrete support cylinder 1.

[0072] In this embodiment, the suspended floor slab 4 includes a floor main beam 41 and a suspended floor slab 42. The hanging column 3 is set on the periphery of the suspended floor slab 4 and connected to the concrete support cylinder 1 through the floor main beam 41. Both ends of the floor main beam 41 are connected to the hanging column 3 and the concrete support cylinder 1, respectively.

[0073] In this embodiment, the topmost hanging column is hinged or rigidly connected to the conversion truss 2, and the suspended floor slab 4 also includes a floor edge beam 43, with the hanging column 3 hinged or rigidly connected to the floor edge beam 43.

[0074] In summary, this invention provides a secondary forming design method for a suspended structure that facilitates the overall lifting of the transfer truss. By dividing the traditional concrete-supported cylinder 1 into an inner cylinder and an outer wall layer for separate construction, a temporary support device is installed after the inner wall layer 11 is completed to temporarily support the transfer truss 2, allowing it to be assembled on the ground. Then, the outer wall layer 12 replaces the temporary support device to permanently support the transfer truss 2. The sequentially constructed inner and outer walls work together to bear the vertical and horizontal loads of the suspended structure. This invention, by employing a secondary construction method for the concrete-supported cylinder 1 and the overall lifting and installation of the roof transfer truss 2 on the ground, eliminates a large amount of vertical transportation and the risks of high-altitude operations, reduces the difficulty of construction and inspection of the suspended structure, improves the construction quality of the suspended structure, and lowers construction costs.

[0075] Furthermore, it should be understood that although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention. For any person skilled in the art, many possible variations and modifications can be made to the technical solutions of the present invention based on the disclosed technical content, or equivalent embodiments can be modified accordingly, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, shall still fall within the scope of protection of the present invention.
