Description

Technical Field

[0001] This invention relates to the field of space frame construction equipment technology, specifically to a space frame cumulative sliding installation structure and a composite cumulative jacking construction method. Background Technology

[0002] Among the existing steel structure space frame installation methods, space frame sliding and space frame jacking are the two most commonly used installation methods. Space frame sliding refers to the method of sliding space frame units one by one to the design position on a pre-set slide rail and completing the splicing. Space frame jacking refers to the method of using hydraulic machinery to lift the space frame assembled on the ground to the design-specified height as a whole, thereby completing the space frame installation.

[0003] Currently, existing technologies disclose construction methods for the overall lifting and sliding installation of space frames. These methods require the overall assembly of the space frame on the ground. The assembled space frame is heavy, difficult to control during sliding and lifting, resulting in low construction efficiency and potential safety hazards. Furthermore, ground assembly requires a sufficiently large assembly area and space for hoisting machinery. The higher the hoisting height and the larger the turning radius, the greater the construction difficulty. Overall lifting and sliding requires careful consideration of the rational arrangement of lifting points during hoisting, ensuring both force balance and preventing deformation of the space frame, thus leading to high construction difficulty and risk. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of high construction difficulty and high construction risk in the overall jacking of the existing technology, thereby providing a space frame cumulative sliding installation structure and a composite cumulative jacking construction method.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0009] According to some embodiments of the present invention, the first steel section is an H-beam, the first steel section includes an upper flange, a lower flange, and a web connecting the upper flange and the lower flange, and reinforcing ribs are provided on both sides of the web of the first steel section.

[0010] According to some embodiments of the present invention, the track includes a first slide rail and a second slide rail laid on both sides of the upper wing plate. The first slide rail and the second slide rail are both made of channel steel and are fixed to the surface of the upper wing plate by welding.

[0011] According to some embodiments of the present invention, the track is marked with graduations at 10mm intervals.

[0012] According to some embodiments of the present invention, the slider is made of steel, a support fixing plate is provided between the slider and the sliding support, and a pressure block is provided on the slider to fix the sliding support on the slider.

[0013] According to some embodiments of the present invention, the driving component is an electric hoist, the driving component is installed at the other end of the first steel section via a reaction point lug, and the driving end of the driving component is connected to the slider to pull the grid frame to slide.

[0014] The present invention also provides a construction method for cumulative sliding and cumulative jacking of a space frame, the steps of which are as follows:

[0015] Construct a sliding installation structure in the first construction area;

[0016] Assemble the first space frame unit on the assembly platform and install the first space frame unit onto the sliding track;

[0017] After the first space frame unit is pulled and slid to a sliding unit by the driving component, the driving component is turned off.

[0018] Repeat the above steps to accumulate, slide and connect multiple first space frame units to form a first space frame assembly;

[0019] After the first space frame component is installed and slid, multiple first space frame units are unloaded from the sliding supports in sequence using jacks;

[0020] Erect a lifting frame on the concrete columns in the second construction area;

[0021] The second space frame unit is lifted by a lifting frame, and steel wire ropes are connected between the lifting frame and the second space frame unit. A limiting device and a horizontal displacement monitoring device are provided between the second space frame unit and the concrete column.

[0022] After one of the second space frame units is lifted to the lifting unit, the lifting steps are repeated to lift and connect multiple second space frame units to form a second space frame assembly;

[0023] After the first space frame component and the second space frame component are connected in combination, the lifting frame is unloaded.

[0024] According to some embodiments of the present invention, a two-layer back-top structure is provided between the sliding installation structure and the concrete beam, with the back-top height ranging from 9.7m to 12.3m.

[0025] The technical solution of this invention has the following advantages:

[0026] 1. The cumulative sliding installation structure for a space frame provided by this invention involves setting up an assembly platform on a concrete beam, with a first steel section extending to the assembly platform and a track on the first steel section. First space frame units are assembled and connected on the assembly platform. After multiple first space frame units are assembled on the platform, they are connected to sliding supports. A driving component drives the sliding supports to slide along the track on the first steel section, achieving cumulative sliding. This cumulative sliding installation structure avoids the need for overall splicing of the top frame, improves the force balance of the space frame during sliding through cumulative sliding, reduces the difficulty of sliding installation, and enhances safety.

[0027] 2. The cumulative sliding installation structure of the space frame provided by the present invention has up to three guardrails on the assembly platform to improve the reliability and safety of the assembly platform and avoid accidents when construction personnel are assembling the first space frame unit.

[0028] 3. In the cumulative sliding installation structure of the space frame provided by the present invention, since the space frame is relatively heavy, in order to improve the reliability of the cumulative sliding installation structure of the space frame, reinforcing ribs are provided on both sides of the web of the first steel to enhance stability.

[0029] 4. The cumulative sliding installation structure of the space frame provided by the present invention will generate vibration during the process of the sliding support being driven to move by the driving component. Since the mass of the space frame is large, in order to avoid the space frame from detaching from the sliding support due to vibration, a pressure block structure is set on the slider to fix the sliding support on the slider, thereby reducing the vibration during the sliding process and improving reliability.

[0030] 5. The construction method of cumulative sliding and cumulative jacking of space frame provided by the present invention installs the space frame to the designated position through cumulative sliding and cumulative jacking. The cumulative sliding and cumulative jacking methods can reduce the constraints of the construction site, avoid using the space frame installed as a whole for sliding and jacking, reduce the difficulty of sliding and jacking, improve construction efficiency, and solve the problem of space frame sliding and jacking that cannot be carried out due to construction site problems. It also improves the stability and safety of space frame sliding and jacking, and achieves safe construction.

[0031] 6. The construction method of cumulative sliding and cumulative jacking of space frame provided by the present invention sets up two layers of back jacking structure between the sliding installation structure and the concrete beam to reduce the impact on the concrete beam during the assembly and sliding of the space frame.

[0039] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] Reference Figures 1 to 5 As shown, the present invention provides a space frame cumulative sliding installation structure, including: an assembly platform 1, a first steel section 2, a sliding support 6, and a driving component 8; the assembly platform 1 is disposed on a concrete beam, and the assembly platform 1 is adapted for the assembly and connection of a first space frame unit 7; the first steel section 2 is disposed on the concrete beam, with one end extending to the assembly platform 1, and a track 3 is laid on the first steel section 2; the sliding support 6 is fixedly connected to the lower chord ball of the space frame, and the lower end of the sliding support 6 is connected to the track 3 through a slider 4, and a traction lug 81 is provided on the sliding support 6; the driving component 8 is disposed at the other end of the first steel section 2, and the output end of the driving component 8 is connected to the traction lug 81 to drive the sliding support 6 to move the space frame on the track 3.

[0044] Specifically, an assembly platform 1 is set on a concrete beam, and a first steel section 2 extends to the assembly platform 1. A track 3 is provided on the first steel section 2. First space frame units 7 are assembled and connected on the assembly platform 1. After multiple first space frame units 7 are assembled on the assembly platform 1, they are connected to sliding supports 6. A driving component 8 drives the sliding supports 6 to slide along the track 3 on the first steel section 2, achieving cumulative sliding. This cumulative sliding installation structure of the space frame avoids the need for overall splicing of the top frame. By using cumulative sliding, it improves the force balance of the space frame during sliding, reduces the difficulty of sliding installation, and improves safety.

[0045] It is understandable that the so-called cumulative sliding involves dividing the entire space frame structure into multiple first space frame units 7, assembling these units separately on the assembly platform 1, and then connecting them by sliding them sequentially using the drive component 8. Specifically, after assembling the first first space frame unit 7 on the assembly platform 1, it is installed on the sliding support 6. The output end of the drive component 8 drives the sliding support 6 to slide on the track 3 set on the first steel section 2, moving the first space frame unit to a unit distance. Then, the second first space frame unit 7 is assembled on the assembly platform 1, and the second first space frame unit 7 is connected to the first space frame unit by the drive component 8. The drive component 8 then slides the connected first and second first space frame units 7 to the next unit distance, repeating the above process until the sliding installation of the entire space frame is completed. In some embodiments of the present invention, a unit distance is 3m. The specific value of a unit distance is not a limitation of the present invention and is determined according to the building structure and the required installation specifications of the space frame.

[0046] In some embodiments of the present invention, the assembly platform 1 includes a ring beam, on which a plurality of second steel sections are horizontally laid, and between two adjacent second steel sections, a plurality of channel steel sections are arranged, and a wooden board structure is laid on the channel steel sections.

[0047] Specifically, the ring beam serves as the main load-bearing component. Multiple second-section steel beams are evenly and horizontally laid on the ring beam. Specifically, adjacent second-section steel beams are spaced 1500mm apart, each second-section steel beam is 8m long, and the specific model of the second-section steel beam is H200×200×8×12. During the assembly of the first space frame unit 7, each lower chord sphere of the space frame is aligned with a second-section steel beam. Straight-seam steel pipes are placed under the lower chord spheres, and the distance between the lower chord spheres and the second-section steel beams is adjusted by the height of the steel pipes to facilitate fixing the first space frame unit 7 to the sliding support 6. It is understood that the specifications and dimensions of the second-section steel beams and the straight-seam steel pipes are not limitations of this invention. Several channel steel beams are laid between adjacent second-section steel beams, spaced 1000mm apart. The channel steel beams are perpendicular to the second-section steel beams and are fixed to them by welding. After fixing the channel steel beams and the second-section steel beams, a wooden plank structure is laid on the channel steel beams to facilitate the movement and operation of construction personnel.

[0048] Reference Figure 2 As shown, in some embodiments of the present invention, the assembly platform 1 is provided with guardrails on up to three sides.

[0049] Specifically, the first steel section 2 extends to the assembly platform 1. Except for the side that contacts the first steel section 2, guardrails are installed on the other three sides of the assembly platform 1 to provide protection for construction personnel, thereby improving the reliability and safety of the assembly platform 1 and preventing accidents from occurring when construction personnel are assembling the first space frame unit 7.

[0050] Reference Figure 3 As shown, in some embodiments of the present invention, the first steel section 2 is an H-beam, the first steel section 2 includes an upper flange, a lower flange and a web connecting the upper flange and the lower flange, and reinforcing ribs 21 are provided on both sides of the web of the first steel section 2.

[0051] Specifically, due to the heavy weight of the space frame, to improve the reliability of its cumulative sliding installation structure, reinforcing ribs 21 are installed on both sides of the web of the first steel section 2 to enhance stability. The reinforcing ribs 21 are spaced 1000mm from the web. (Refer to...) Figure 3 As shown, the first steel section 2 is fixed to the concrete column by pre-embedded bolts.

[0052] Reference Figure 4 As shown, in some embodiments of the present invention, the track 3 includes a first slide rail and a second slide rail laid on both sides of the upper wing plate. The first slide rail and the second slide rail are both made of channel steel, and the first slide rail and the second slide rail are fixed to the surface of the upper wing plate by welding.

[0053] In some embodiments of the present invention, the track 3 is marked with graduations at 10mm intervals.

[0054] Specifically, the first slide rail, the second slide rail, and the first steel section 2 are fixedly connected by forging and welding. Scale lines are marked on the track 3 at 10mm intervals to facilitate simultaneous observation of both the first and second slide rails during the sliding process of the space frame, maintaining communication and thus controlling the sliding deviation.

[0055] Reference Figure 5 As shown, in some embodiments of the present invention, the slider 4 is made of steel, a support fixing plate 5 is provided between the slider 4 and the sliding support 6, and a pressure block 41 suitable for fixing the sliding support 6 on the slider 4 is provided on the slider 4.

[0056] Specifically, the slider 4 has dimensions of 70×100×750mm. The upper surface of the slider 4 is fixedly connected to the sliding support 6 via a pressure block 41. The pressure block 41 includes a connected horizontal portion and a vertical portion. The sliding support 6 extends into the right-angled area formed by the horizontal and vertical portions, abutting against both portions. The horizontal portion presses the sliding support 6 onto the slider 4. During the movement of the sliding support 6 driven by the driving component 8, vibrations occur. Due to the large mass of the space frame, to prevent vibrations from causing the space frame to detach from the sliding support 6, a pressure block 41 structure is provided on the slider 4 to fix the sliding support 6 onto the slider 4, thereby reducing vibrations during the sliding process and improving reliability. Multiple pressure blocks 41 can be provided to ensure force balance on the sliding support 6 and improve stability. The specifications of the slider 4 and the number of pressure blocks 41 are not limitations of this invention. Before sliding, lubricant is applied to the contact surfaces of the track 3 and the bottom of the slider 4. Specifically, the lubricant is glycerol ester to reduce friction between the slider 4 and the track 3 surface and improve sliding efficiency.

[0057] In some embodiments of the present invention, the driving component 8 is an electric hoist, the driving component 8 is installed at the other end of the first steel section 2 through the reaction point ear plate 82, and the driving end of the driving component 8 is connected to the slider 4 to pull the grid frame to slide.

[0058] Specifically, in some embodiments of the present invention, an electric hoist is used as the driving component 8. The driving component 8 is fixed to the other side of the first steel 2 through the reaction point ear plate 82. The output end of the driving component 8 is connected to the traction ear plate 81 through a steel wire rope to drive the sliding support 6 to slide.

[0059] The present invention also provides a construction method for cumulative sliding and cumulative jacking of a space frame, the steps of which are as follows:

[0060] In the first construction area, a sliding installation structure is erected; specifically, according to the construction site conditions and the layout of the building structure, an assembly platform 1 is first erected, and then the first steel section 2 is laid on the concrete beam, and the sliding track 3 is arranged.

[0061] Assemble the first space frame unit 7 on the assembly platform 1, and install the first space frame unit 7 onto the sliding track 3;

[0062] Specifically, the construction workers assemble the first space frame unit 7 on the assembly platform 1 and install the first space frame unit 7 on the sliding track 3 through the sliding support 6.

[0063] After the first space frame unit 7 is traction and slid to a sliding unit by the driving component 8, the driving component 8 is turned off.

[0064] Repeat the above steps to accumulate, slide and connect multiple first space frame units 7 to form a first space frame assembly;

[0065] Specifically, the first assembled space frame unit 7 is slid and pulled to a sliding unit (3m) using the driving component 8. Then, the second space frame unit 7 is assembled on the assembly platform 1. Similarly, the second space frame unit 7 is slid and connected to the first space frame unit 7 using the driving component 8, forming a first space frame assembly. The space frame assembly is then slid to the next sliding unit using the driving component 8. This method of sequentially sliding and assembling individual space frame units is called the cumulative sliding method. Through this cumulative sliding and cumulative jacking method, the space frame is installed to the designated position. The cumulative sliding method reduces site constraints, avoids using a fully installed space frame for sliding, reduces sliding difficulty, and improves construction efficiency. It also solves the problem of space frame sliding being impossible due to site limitations, improving the stability and safety of space frame sliding and jacking, and achieving safe construction.

[0066] After the first space frame assembly is installed and slid, multiple first space frame units 7 are unloaded from the sliding support 6 in sequence using jacks;

[0067] A jacking frame was erected on the concrete columns in the second construction area. Specifically, the jacking frame was installed in the upper part of the concrete columns. The position of the jacking frame was simulated and optimized using 3D software to ensure that the jacking frame remained structurally stable during the jacking process.

[0068] The second space frame unit is lifted by a lifting frame, and steel wire ropes are connected between the lifting frame and the second space frame unit. A limiting device and a horizontal displacement monitoring device are provided between the second space frame unit and the concrete column.

[0069] By tying steel wire ropes between the lifting frame and the second space frame unit, and by tying guide ropes between the second space frame unit and the surrounding concrete columns, the smooth lifting of the second space frame unit can be controlled.

[0070] Once a second space frame unit is lifted to the threshold height, the lifting process is repeated to lift and connect multiple second space frame units to form a second space frame assembly.

[0071] By using cumulative jacking and cumulative sliding, the space frame is installed to the designated position. Cumulative jacking can reduce the constraints of the construction site, avoid using the space frame as a whole for jacking, reduce the jacking difficulty, improve construction efficiency, and avoid construction accidents caused by the excessive mass of the whole space frame during the jacking process.

[0072] After the first space frame component and the second space frame component are connected in combination, the lifting frame is unloaded.

[0073] It is understandable that cumulative sliding and cumulative jacking can be implemented simultaneously or separately. By using a combination of cumulative sliding and cumulative jacking, the space frame is installed in the designated position, ensuring the safety and reliability of the construction process while reducing construction difficulty and improving construction efficiency.

[0074] According to some embodiments of the present invention, a two-layer back-top structure is provided between the sliding installation structure and the concrete beam, with the back-top height ranging from 9.7m to 12.3m.

[0075] Specifically, a two-layer backfill structure is set between the sliding installation structure and the concrete beam to reduce the impact on the concrete beam during the assembly and sliding of the space frame.

[0076] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
