Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a super-large span steel spherical dome structure and its hoisting construction method. Background Technology

[0002] For the installation of airports or large-span buildings with ultra-large span steel spherical dome structures, due to the large volume and span of the dome structure, the hoisting of large-span steel structures will inevitably require large-scale lifting measures. How to complete the hoisting safely, efficiently, quickly, and with low consumption is of paramount importance.

[0003] Existing technologies have low installation efficiency for dome structures, which seriously affects the construction period. Furthermore, the connection of the main steel beams of the dome structure is unreliable after installation, which affects the construction quality of the dome structure. Summary of the Invention

[0004] This invention provides an ultra-large span steel spherical dome structure and its hoisting construction method, with the aim of improving the connection reliability of the dome structure.

[0005] This invention is achieved through the following technical solution: a super-large span steel structure spherical dome structure, including a longitudinal main steel beam and multiple layers of latitudinal main steel beams. The longitudinal main steel beam includes a first main steel beam, a second main steel beam, and multiple sets of auxiliary steel beams. The first main steel beam and the second main steel beam are fixed in a cross shape. The multiple sets of auxiliary steel beams are circumferentially distributed in the area between the first main steel beam and the second main steel beam and are connected to the first main steel beam and the second main steel beam as a whole. The multiple layers of latitudinal main steel beams are distributed at intervals along the length direction of the longitudinal main steel beams. The latitudinal main steel beams are used to circumferentially connect the first main steel beam, the second main steel beam, and the multiple sets of auxiliary steel beams.

[0006] Compared with existing technologies, this solution has the following advantages and beneficial effects:

[0007] The dome structure in this design consists of longitudinal main steel beams and latitudinal main steel beams. The latitudinal main steel beams connect the longitudinal main steel beams to form a unified structure. This allows the longitudinal and latitudinal directions of the entire dome structure to be distributed in an alternating mesh pattern, which effectively improves the strength and load-bearing capacity of the entire dome structure. Furthermore, multiple sets and layers of latitudinal main steel beams are provided, which are spaced apart along the length of the longitudinal main steel beams. This allows for connection and reinforcement of the upper, middle, and lower parts of the longitudinal main steel beams, effectively improving the connection reliability of the dome structure.

[0008] In addition, the meridional main steel beam in this scheme includes a first main steel beam, a second main steel beam, and multiple sets of auxiliary steel beams. The first and second main steel beams are fixed in a cross shape, which facilitates the positioning of the multiple sets of auxiliary steel beams and makes the installation of the entire meridional main steel beam more convenient and faster.

[0009] Furthermore, the first main steel beam, the second main steel beam, and the secondary steel beam are all arc-shaped structures.

[0010] Beneficial effects: This design enhances the aesthetics of the completed dome structure, and the arc-shaped main steel beams are easier to install.

[0011] Furthermore, it also includes a central beam, which is ring-shaped and connected to the upper part of the first main steel beam and the second main steel beam. The top ends of the multiple sets of secondary steel beams are all fixedly connected to the central beam.

[0012] Beneficial effects: The central beam in this design allows the tops of the first main steel beam, the second main steel beam, and multiple sets of secondary steel beams to be connected to the central beam, thus forming a unified structure. Furthermore, the central beam ensures that the meridional main steel beams are neatly and orderly distributed on the outside of the central beam, making connection and fixing easier and resulting in a more aesthetically pleasing and orderly dome structure.

[0013] Furthermore, the first main steel beam, the second main steel beam, and the secondary steel beam are all composed of two symmetrically arranged steel beams. The top ends of the two steel beams of the secondary steel beam are connected to the outer wall of the central beam. The top ends of the two steel beams of the first and second main steel beams are connected to each other and then connected to the central beam.

[0014] Beneficial effects: In this design, the main meridional steel beam consists of steel beams symmetrically arranged at both ends. This facilitates the separate hoisting of the two sections of the main meridional steel beam during installation. This is very suitable for hoisting applications of dome structures with large building areas and heavy steel beams. This structural design in this design can improve installation efficiency, reduce installation costs, and enhance safety.

[0015] Furthermore, the central beam is composed of four arc segments, which are located between the four corners of the first main steel beam and the second main steel beam and are connected to the first main steel beam and the second main steel beam, respectively.

[0016] Beneficial effects: This arrangement facilitates the connection and fixation of the central beam with the first and second main steel beams, and better adapts to the intersection of the first and second main steel beams. It allows the central beam to be flush with the top of the first and second main steel beams, resulting in better fit between the secondary steel beams and the first and second main steel beams. This ensures that the installation position of the secondary steel beams is consistent with the installation positions of the first and second main steel beams in terms of elevation, verticality, and other parameters. Consequently, the top of the resulting dome structure better meets construction requirements, is more aesthetically pleasing, and is smoother and flatter.

[0017] Furthermore, the latitudinal main steel beam is composed of multiple supporting steel beams, each of which is sequentially connected between two adjacent secondary steel beams and between the secondary steel beams and the first and second main steel beams.

[0018] Beneficial effects: In this scheme, the latitudinal main steel beam is composed of multiple supporting steel beams. This facilitates the simultaneous construction of the longitudinal main steel beams and the timely connection and fixation of the constructed longitudinal main steel beams. This ensures a smoother process when hoisting the next set of longitudinal main steel beams and ensures the stability between the already hoisted radial main steel beams, preventing skew displacement that could affect the overall installation accuracy. This also makes the installation of the latitudinal main steel beams more convenient. Compared to hoisting all the longitudinal main steel beams before installing the latitudinal main steel beams, this scheme, which breaks down each set of latitudinal main steel beams into multiple supporting steel beams for installation, is smaller in size and easier and faster to connect and fix.

[0019] The hoisting construction method for a super-large span steel spherical dome structure includes a central beam, longitudinal main steel beams, and multiple layers of latitudinal main steel beams. The main steel beams include a first main steel beam, a second main steel beam, and multiple sets of secondary steel beams. The hoisting construction method for the super-large span steel spherical dome structure includes the following steps:

[0020] S1, install the cross-shaped radial main steel beam, hoist the first main steel beam and the second main steel beam, so that the first main steel beam and the second main steel beam form a cross-shaped structure;

[0021] S2, Install the secondary steel beams, hoist multiple sets of secondary steel beams in sequence, so that the multiple sets of secondary steel beams are distributed circumferentially in the area between the first main steel beam and the second main steel beam, and connect the secondary steel beams with the first main steel beam and the second main steel beam to form a whole;

[0022] S3, Install the latitudinal main steel beams. The multiple latitudinal main steel beams are distributed at intervals along the length of the longitudinal main steel beams. The multiple latitudinal main steel beams connect the first main steel beam, the second main steel beam, and multiple sets of auxiliary steel beams into one unit.

[0023] Beneficial effects: The construction method in this scheme first installs the cross-shaped radial main steel beam, which serves as a positioning tool and facilitates the installation of the remaining radial main steel beams. This assists in the installation of multiple sets of secondary steel beams, ensuring that the multiple sets of secondary steel beams are circumferentially distributed in the area between the first and second main steel beams, thereby effectively improving installation accuracy.

[0024] In addition, this construction method also includes the installation of latitudinal main steel beams, which forms a mesh structure and improves the connection strength and stability of the entire structure.

[0025] Furthermore, the first main steel beam, the second main steel beam, and the auxiliary steel beam are all composed of two symmetrically arranged steel beams. In S1, the two steel beams of the first main steel beam are hoisted symmetrically, and the top ends of the two steel beams of the first main steel beam are joined and fixed. Then, the two steel beams of the second main steel beam are hoisted symmetrically, and the top ends of the two steel beams of the second main steel beam are connected and fixed to the top sidewalls of the two steel beams of the first main steel beam.

[0026] A ring-shaped central beam is connected to the top of the first and second main steel beams;

[0027] In S2, the two sections of the secondary steel beams of each group are hoisted symmetrically in sequence, and the tops of the two sections of the secondary steel beams are connected and fixed to the outside of the central beam.

[0028] Beneficial effects: In this scheme, two hoisting machines can be used simultaneously to hoist and connect two sections of a set of radial main steel beams. Compared with hoisting the radial main steel beams as a single structure, which is much more difficult due to their larger size and heavier weight, this scheme is simpler, more convenient, and more efficient.

[0029] Because of the central beam, a connection point can be provided at the top of the secondary steel beam when it is hoisted, making installation easier and resulting in a higher quality structure.

[0030] Furthermore, the latitudinal main steel beam is composed of multiple supporting steel beams. When installing the secondary steel beams in S2, after each set of secondary steel beams is installed, it is connected to the adjacent secondary steel beam or the meridional main steel beam through one of the supporting steel beams of the latitudinal main steel beam.

[0031] Beneficial effects: This solution can ensure the stability and firmness of the pre-installed radial main steel beam, making it less likely for the radial main steel beam to shift in position, thereby ensuring the installation accuracy of the entire structure.

[0032] Furthermore, when installing the latitudinal main steel beams, first install two layers of latitudinal main steel beams, and then complete the installation of the remaining latitudinal main steel beams after all the secondary steel beams have been installed.

[0033] Beneficial effects: This setup, with two layers of latitudinal main steel beams, can limit and fix the longitudinal main steel beams. This can improve the stability of the already installed longitudinal main steel beams while increasing installation efficiency. If each layer of latitudinal main steel beams is installed before hoisting the next section of longitudinal main steel beams, the overall installation efficiency will be greatly affected.

[0034] In this scheme, after all the radial main steel beams are installed, the zonal main steel beams of the remaining layers are then installed. When installing the zonal main steel beams of the remaining layers, the zonal main steel beams can be split into several steel beams with a length greater than the support steel beams and assembled on the outside of all the radial main steel beams that have been installed. This can improve the operation efficiency and reduce the construction cycle. Attached Figure Description

[0056] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0057] Example 1

[0058] like Figures 1-2As shown, this embodiment 1 provides an ultra-large span steel structure spherical dome structure, including a meridional main steel beam and multiple latitudinal main steel beams 4. The meridional main steel beam includes a first main steel beam 1, a second main steel beam 2 and multiple sets of secondary steel beams 3. The first main steel beam 1 and the second main steel beam 2 are cross-shaped and fixed. In this embodiment, the first main steel beam 1, the second main steel beam 2 and the secondary steel beams 3 are all arc-shaped structures, which makes the completed dome structure arch-shaped and more aesthetically pleasing.

[0059] Multiple sets of secondary steel beams 3 are circumferentially distributed in the area between the first main steel beam 1 and the second main steel beam 2 and are connected to the first main steel beam 1 and the second main steel beam 2 as a whole. Specifically, the ultra-large span steel structure spherical dome structure also includes a central beam 5, which is ring-shaped and connected to the upper part of the first main steel beam 1 and the second main steel beam 2. In this embodiment, the central beam 5 is close to the top of the first main steel beam 1 and the second main steel beam 2. The tops of the multiple sets of secondary steel beams 3 are all welded and fixedly connected to the central beam 5.

[0060] In this embodiment, the first main steel beam 1, the second main steel beam 2, and the secondary steel beam 3 are all composed of two symmetrically arranged steel beams. The top ends of the two steel beams of the secondary steel beam 3 are connected to the outer wall of the central beam 5. The top ends of the two steel beams of the first main steel beam 1 and the second main steel beam 2 are welded together and then connected to the central beam 5. Specifically, in this embodiment, the central beam 5 is composed of four arc segments. The four arc segments are located between the four corners of the first main steel beam 1 and the second main steel beam 2 and are welded and fixed to the first main steel beam 1 and the second main steel beam 2.

[0061] In this embodiment, the latitudinal main steel beams 4 are arranged in a ring, and the multiple latitudinal main steel beams 4 are distributed at intervals along the length direction of the longitudinal main steel beams, thus forming a structure of multiple latitudinal main steel beams 4. The latitudinal main steel beams 4 are used to connect the first main steel beam 1, the second main steel beam 2 and multiple sets of auxiliary steel beams 3 in a ring, so as to realize the multi-layer connection and fixation of the longitudinal main steel beams, and improve the overall strength and firmness.

[0062] In this embodiment, the latitudinal main steel beam 4 is composed of multiple supporting steel beams. Each supporting steel beam is sequentially connected between two adjacent secondary steel beams 3 and between the secondary steel beam 3 and the first main steel beam 1 and the second main steel beam 2. This makes the installation of the latitudinal main steel beam 4 more convenient, the fixing construction speed is faster, and it occupies less space, making it easier for workers to connect and fix between the longitudinal main steel beams.

[0063] Example 2 differs from Example 1 in that it provides a construction method for hoisting the ultra-large span steel spherical dome structure from Example 1. The hoisting construction method for the ultra-large span steel spherical dome structure in this example includes the following steps:

[0064] S1, install the cross-shaped main steel beams, hoist the first main steel beam 1 and the second main steel beam 2, so that the first main steel beam 1 and the second main steel beam 2 form a cross-shaped structure; since the first main steel beam 1, the second main steel beam 2 and the secondary steel beam 3 are all composed of two symmetrically arranged steel beams, in S1, combined with Figure 3 and Figure 4 As shown, a crane is used to symmetrically lift the two sections of the first main steel beam 1, and then the top ends of the two sections of the first main steel beam 1 are joined together and welded to fix them. Then, the two sections of the second main steel beam 2 are symmetrically lifted and the top ends of the two sections of the second main steel beam 2 are welded to the top side walls of the two sections of the first main steel beam 1 respectively.

[0065] In this embodiment, a ring-shaped central beam 5 is connected to the top of the first main steel beam 1 and the second main steel beam 2. The four arc segments of the central beam 5 are welded to the four corners of the first main steel beam 1 and the second main steel beam 2 respectively. The width of the central beam 5 is the same as the width of the first main steel beam 1 and the second main steel beam 2, so that the central beam 5 is flush with the first main steel beam 1 and the second main steel beam 2. This ensures the flatness of the installation and improves the aesthetics of the entire building.

[0066] S2, Install the secondary steel beams 3, and hoist multiple sets of secondary steel beams 3 in sequence so that the multiple sets of secondary steel beams 3 are evenly distributed in the circumferential direction in the area between the first main steel beam 1 and the second main steel beam 2, and connect the secondary steel beams 3 with the first main steel beam 1 and the second main steel beam 2 into one unit. In this embodiment, the two sections of steel beams of each set of secondary steel beams 3 are hoisted symmetrically in sequence, and the top of the two sections of steel beams of the secondary steel beams 3 are welded and fixed to the outside of the center beam 5.

[0067] S3, install the latitudinal main steel beam 4. The multiple latitudinal main steel beams 4 are distributed at intervals along the length of the longitudinal main steel beam. The multiple latitudinal main steel beams 4 connect the first main steel beam 1, the second main steel beam 2 and multiple sets of secondary steel beams 3 into one unit. In this embodiment, the latitudinal main steel beam 4 is composed of multiple support steel beams. When installing the secondary steel beams 3 in S2, after each set of secondary steel beams 3 is installed, it is connected to the adjacent secondary steel beams 3 or longitudinal main steel beams through one of the support steel beams of the latitudinal main steel beam 4. This can ensure the stability and reliability of the installed secondary steel beams 3.

[0068] When installing the latitudinal main steel beam 4, first install two layers of latitudinal main steel beam 4, and finally, after all the secondary steel beams 3 are installed, complete the installation of the remaining latitudinal main steel beam 4.

[0069] Specifically: In the actual construction process, the on-site hoisting of steel components is divided into the following eight steps:

[0070] 1. Install the cross-shaped radial main steel beam, such as Figure 5As shown, the two sections of the first main steel beam 1 are lifted by a crane and installed symmetrically. After the lifting is completed, the elevation, axis, and verticality are checked, and then the two sections of the first main steel beam 1 are butt-welded together. Figure 6 As shown, the two sections of the second main steel beam 2 are lifted by a crane to ensure symmetrical installation. After the lifting is completed and the elevation, axis, and verticality are checked, the two sections of the second main steel beam 2 are then welded together.

[0071] 2. For example Figure 7 As shown, the center beam 5 is installed so that its four arc segments are symmetrically installed and then welded and fixed between the first main steel beam 1 and the second main steel beam 2 in sequence.

[0072] 3. For example Figure 8 As shown, the sub-steel beams 3 in the southeast and northwest sections are installed, symmetrically hoisted, and their tops are welded to the central beam 5 for fixation. Figure 9 As shown, two cranes are added to the southeast and northwest sections to lift two sections of the latitudinal main steel beam 4, which are respectively welded between the newly installed secondary steel beam 3 and the first main steel beam 1. The two sections of the latitudinal main steel beam in the southeast section and the two sections of the latitudinal main steel beam in the northwest section are respectively located in the lower two layers of the multi-layer latitudinal main steel beam 4 installation position.

[0073] 4. For example Figure 10 As shown, continue to hoist the sub-steel beams 3 in the southeast and northwest parts symmetrically, and weld the top of the sub-steel beams 3 to the central beam 5 for fixation. After each set of sub-steel beams 3 is hoisted, the two end support steel beams of the latitudinal main steel beam 4 can be hoisted and welded to the two adjacent sub-steel beams 3 respectively. The support steel beams are then welded and fixed sequentially according to the height position of the support steel beams welded in the previous welding to form a whole.

[0074] 5. For example Figure 11 As shown, after half of the sub-steel beam 3 is hoisted in the southeast and northwest areas, the other half of the sub-steel beam 3 is hoisted in the opposite direction, and the support steel beams of the latitudinal main steel beam 4 are welded according to the above operation steps.

[0075] 6. For example Figure 12 As shown, the installation continues until all the secondary steel beams 3 in the southeast and northwest regions are installed.

[0076] like Figure 13 As shown, once the support beams of the last section of the latitudinal main steel beam 4 are installed, the installation of the secondary steel beams 3 in the southeast and northwest sections can be completed.

[0077] 7. Next, begin installing the secondary steel beams 3 in the southwest and northeast sections, such as... Figure 14 , 15As shown, install the secondary steel beam 3 and the lateral main steel beam 4 according to the steps described above. First, install the secondary steel beam 3 clockwise. After half of the secondary steel beam 3 in the southwest and northeast sections is installed, proceed as follows: Figure 16 and Figure 17 As shown, install the remaining secondary steel beam 3 and support steel beam counterclockwise.

[0078] 8. For example Figure 18 As shown, the installation of the remaining latitudinal main steel beams 4 will complete the hoisting of the entire dome structure.
