Description

Technical Field

[0001] This invention relates to the field of modular construction technology, and in particular to a construction platform and construction method suitable for large-span modular steel structures. Background Technology

[0002] To address the issues of numerous jigs and high steel consumption in current large-module sliding construction methods, a sliding jig construction technology for large modules is proposed. Compared to the existing "full array of fixed jigs + high-altitude jacking and sliding" method, this proposed "sliding jig + ground jacking and sliding" construction technology not only significantly reduces the number of jigs used and improves jig utilization efficiency but also eliminates the dangers of high-altitude jacking and sliding. Its innovation lies in the installation of sliding guide rails on the top surface of the concrete structure, with a jacking device and sliding jig positioned above the guide rails. The jacking device pushes the sliding jig, which then moves the large module to the designated location. Summary of the Invention

[0011] The sliding lifting frame and the sliding jig are used to transport building module units.

[0012] Furthermore, the main sliding guide rail and the lifting sliding guide rail are arranged at the same horizontal height;

[0013] The main sliding guide rail and the lifting sliding guide rail are disconnected at their intersection, and a conversion guide rail is provided to connect the disconnected main sliding guide rail and / or the lifting sliding guide rail.

[0014] Furthermore, the conversion guide rail is a straight-line conversion guide rail;

[0016] The length of the linear conversion guide rail is equal to the distance between the break points of the main sliding guide rail and the lifting sliding guide rail;

[0017] The linear conversion guide rail can switch between the longitudinal and transverse directions, thereby enabling the switching between the connection of the main body sliding guide rail and the connection of the lifting sliding guide rail.

[0018] Furthermore, the main platform includes a lower structure and a large module support structure;

[0019] The lower structure is used to provide support for the main sliding guide rail;

[0082] Example 1

[0083] like Figure 1 As shown, this embodiment provides a construction platform suitable for large-span modular steel structures, including a main platform 1, a lifting platform 2, a main sliding guide rail 3, a lifting sliding guide rail 4, a sliding lifting frame 5, and a sliding jig 6;

[0084] The main platform 1 is erected on the ground or other buildings;

[0085] The lifting platform 2 is located on the side of the main platform 1;

[0086] The main body sliding guide rail 3 is fixedly mounted on the main body platform 1 along the axial direction of the main body platform 1;

[0087] A portion of the lifting sliding guide rail 4 is fixedly mounted on the lifting platform 2 along the axial direction of the lifting platform 2, and one end near the main sliding guide rail 3 extends to the main platform 1 and intersects the main sliding guide rail 3 orthogonally.

[0088] The sliding lifting frame 5 is slidably mounted on the lifting sliding guide rail 4;

[0089] The sliding frame 6 is slidably mounted on the main body sliding guide rail 3;

[0090] The sliding lifting frame 5 and the sliding jig 6 are used to transport the building module unit 7.

[0091] This embodiment discloses a construction platform suitable for large-span modular steel structures, which is used to sequentially transport multiple building module units 7 and ultimately assemble them into a large-span modular steel structure building. In this embodiment, the building module unit 7 is first placed on a sliding lifting frame 5. The sliding lifting frame 5 transports the building module unit 7 along the lifting sliding guide rail 4 and places it on a sliding jig 6. Then, the sliding jig 6 transports the building module unit 7 along the main sliding guide rail 3 to a designated location. This process is repeated to achieve the transportation and assembly of the large-span modular steel structure building. This application differs from existing technologies (such as...). Figure 14 Compared to the previous method, the use of a sliding frame greatly saves on the frame structure and an original construction method for the sliding frame solution was designed.

[0092] In actual construction, this construction platform demonstrated significant advantages. The sliding design of the sliding lifting frame 5 and the sliding jig 6 made the transportation of the building module unit 7 more flexible and efficient. Construction personnel could precisely control the moving distance and speed of the sliding lifting frame and the sliding jig according to actual needs, ensuring that the building module unit 7 could be accurately transported to the designated location. At the same time, this design greatly reduced the intensity and risk of manual handling, improving construction safety and efficiency. Furthermore, the construction platform also has good adaptability and scalability, and can be customized and adjusted according to the needs of different large-span modular steel structure buildings, providing a more convenient and efficient solution for building construction.

[0093] As a further embodiment of this embodiment, the main body sliding guide rail 3 and the lifting sliding guide rail 4 are arranged at the same horizontal height;

[0094] The main sliding guide rail 3 and the lifting sliding guide rail 4 are disconnected at their intersection, and a conversion guide rail 8 is provided to connect the disconnected main sliding guide rail 3 and / or the lifting sliding guide rail 4.

[0095] In this application, the main sliding guide rail 3 and the lifting sliding guide rail 4 intersect vertically on the same horizontal plane. When the sliding lifting frame 5 and the sliding jig 6 run to the intersection, the opposing tracks will obstruct the operation of the frame. Therefore, in this application, the main sliding guide rail 3 and the lifting sliding guide rail 4 are disconnected and a conversion guide rail 8 is set at the disconnection gap to solve the above problem.

[0096] like Figure 2-3 As shown, as a further implementation of this embodiment, the conversion guide rail 8 is a straight conversion guide rail 9;

[0097] The distance between the disconnection points of the main sliding guide rail 3 and the lifting sliding guide rail 4 is equal;

[0098] The length of the linear conversion guide rail 9 is equal to the distance between the break points of the main sliding guide rail 3 and the lifting sliding guide rail 4;

[0099] The linear conversion guide rail 9 can switch between the longitudinal and transverse directions, thereby enabling the switching between the connection of the main body sliding guide rail 3 and the connection of the lifting sliding guide rail 4.

[0100] In this embodiment, a straight-line conversion guide rail 9 is used to switch the connection state between the main sliding guide rail 3 and the lifting sliding guide rail 4. When the sliding lifting frame 5 moves along the lifting sliding guide rail 4, the straight-line conversion guide rail 9 switches to the coaxial direction with the lifting sliding guide rail 4, thereby connecting the lifting sliding guide rail 4. When the sliding frame 6 moves along the main sliding guide rail 3, the straight-line conversion guide rail 9 switches to the coaxial direction with the main sliding guide rail 3, thereby connecting the main sliding guide rail 3.

[0101] This design allows for smoother movement of the sliding lifting frame 5 and the sliding jig 6 on their respective guide rails, eliminating obstructions caused by discontinuities in the guide rails. Simultaneously, the switching operation of the straight-line conversion guide rail 9 is simple, allowing switching between longitudinal and lateral directions via a corresponding control mechanism, significantly improving construction efficiency. Furthermore, the straight-line conversion guide rail 9 possesses high stability and reliability, capable of withstanding various forces generated during the movement of the sliding lifting frame 5 and the sliding jig 6, ensuring the safe operation of the entire transportation process.

[0102] like Figure 1 As shown, as a further embodiment of this example, the main platform 1 includes a lower structure 10 and a large module support structure 11;

[0103] The lower structure 10 is used to provide support for the main sliding guide rail 3;

[0104] The large module support structure 11 is spaced apart on both sides of the lower structure 10 to provide support for the building module unit 7 placed on it.

[0105] like Figure 4 As shown, as a further embodiment of this example, the lifting platform 2 includes a support device 12 and a diagonal brace 13;

[0106] The lower end of the bearing device 12 is a long plate-shaped structure, which is used to evenly transmit the pressure from above to the building or ground below.

[0107] The upper part of the bearing device 12 is a columnar structure, which is used to support the lifting sliding guide rail 4 fixed at its upper end;

[0108] The diagonal brace 13 supports the bearing device 12 from the side to prevent the bearing device 12 from collapsing or tilting.

[0109] like Figure 5 As shown, as a further embodiment of this example, the main sliding guide rail 3 includes a lower first bottom beam 14 and an upper first guide rail body 15.

[0110] The first bottom beam 14 is erected on the main platform 1;

[0111] The first guide rail body 15 is integrally mounted on the upper end surface of the first bottom beam 14;

[0112] The upper part of the first guide rail body 15 and the lower end of the sliding frame 6 are slidably connected.

[0113] like Figure 5 As shown, as a further embodiment of this example, the lifting sliding guide rail 4 includes a lower second bottom beam 16 and an upper second guide rail body 17.

[0114] The second bottom beam 16 is mounted on the bearing device 12;

[0115] The second guide rail body 17 is integrally mounted on the upper end surface of the second bottom beam 16;

[0116] The upper part of the second guide rail body 17 and the lower end of the sliding lifting frame 5 are slidably connected.

[0117] As a further embodiment of this example, the lower ends of the sliding frame 6 and the sliding lifting frame 5 are provided with a sliding groove structure 18 for slidably connecting with the main sliding guide rail 3 and the lifting sliding guide rail 4.

[0118] In a preferred embodiment, the sliding groove structure 18 is provided with a wear-resistant layer made of high-strength alloy material, which can effectively reduce wear during sliding and extend the service life of the equipment. Simultaneously, a lubrication device is provided at the connection between the sliding frame 6 and the sliding lifting frame 5. This lubrication device can automatically release lubricant periodically to ensure smooth sliding and reduce noise caused by friction. Furthermore, to improve the overall stability of the equipment, auxiliary support structures are provided on the sides of the sliding frame 6 and the sliding lifting frame 5. These auxiliary support structures can provide additional support during equipment operation to prevent shaking or displacement.

[0119] As a further embodiment of this invention, a pusher (not shown in the figure) is also included.

[0120] The pusher is mounted on the sliding lifting frame 5 and the sliding tire frame 6, and is used to drive the sliding lifting frame 5 and the sliding tire frame 6 to move.

[0121] The pusher described in this application may employ existing technology, and this application does not impose further limitations.

[0122] like Figure 15 As shown, as a further embodiment of this example, a jack 31 is provided at the top of the sliding lifting frame 5;

[0123] The jack 31 is equipped with a steel strand 32 for driving;

[0124] The end of the steel strand 32 away from the jack 31 is connected to the building module unit 7;

[0125] The sliding lifting frame uses jacks and steel strands to raise and lower the building module unit 7. The jacks 31 are hydraulically driven and feature high-precision synchronous control to ensure the building module unit 7 maintains a stable posture during lifting. The steel strands 32 are pre-tensioned, possessing high tensile strength and corrosion resistance, making them suitable for long-term load-bearing operations.

[0126] By adopting the above technical solution, the present invention has the following beneficial effects:

[0127] (1) By setting up the main platform 1, the lifting platform 2 and the supporting sliding guide rail, sliding lifting frame 5 and sliding frame 6, the sequential transportation and precise assembly of the building module unit 7 are realized, which effectively improves the construction efficiency of large-span modular steel structure buildings.

[0128] (2) The main sliding guide rail 3 and the lifting sliding guide rail 4 are set at the same horizontal height, and the cross is disconnected and a conversion guide rail 8 is set. This solves the problem that the sliding lifting frame 5 and the sliding jig 6 are obstructed at the cross, ensuring the smooth progress of the construction process and improving the safety and reliability of the construction.

[0129] (3) The use of a straight-line conversion guide rail 9 enables flexible switching between the main sliding guide rail 3 and the lifting sliding guide rail 4, further improving the flexibility and efficiency of the construction process.

[0130] (4) The main platform 1 includes a lower structure 10 and a large module support structure 11. The lower structure 10 provides support for the main sliding guide rail 3, while the large module support structure 11 provides stable support for the building module unit 7. The lifting platform 2 includes a load-bearing device 12 and a diagonal brace 13. The load-bearing device 12 evenly transmits the pressure from above to below, while the diagonal brace 13 supports the load-bearing device 12 from the side to prevent it from collapsing or tilting. These designs ensure the stability and safety of the construction platform.

[0131] (5) Both the main sliding guide rail 3 and the lifting sliding guide rail 4 adopt an integrated design. The guide rail body is tightly connected to the bottom beam, ensuring the stability and durability of the guide rail. The sliding frame 6 and the sliding lifting frame 5 are equipped with a sliding groove structure 18 at the lower end, which can be slidably connected to the guide rail, realizing the smooth movement of the frame.

[0132] (6) The jacking device drives the sliding lifting frame 5 and the sliding frame 6 to move, providing flexible power support for the construction process. The movement speed and direction of the frame can be adjusted according to actual needs, which further improves the construction efficiency.

[0133] Example 2

[0134] like Figure 6-13 As shown in the figure, this embodiment provides a construction method suitable for large-span modular steel structures, including the following steps:

[0135] X1: Transport the building module unit to the sliding lifting frame above the lifting platform, and the sliding lifting frame will raise the height of the building module unit;

[0136] X2: The sliding lifting frame moves along the lifting sliding guide rail and the straight-line conversion guide rail that connects the gap of the lifting sliding guide rail and transports the raised building module unit to the top of the sliding frame. The sliding lifting frame lowers the height of the building module unit so that the building module unit is placed on the sliding frame and locked.

[0137] X3: The sliding lifting frame moves in the reverse direction back to the initial position and receives the next building module unit, turning the direction of the straight-line conversion guide rail by 90 degrees, so that the lifting sliding guide rail is disconnected while the main sliding guide rail is connected.

[0138] X4: The sliding frame moves along the main sliding guide rail and the straight conversion guide rail that connects the gap of the main sliding guide rail, thereby moving the building module unit above the large module support structure and placing the building module unit on the large module support structure and fixing it;

[0139] X5: The sliding frame moves in the reverse direction back to the initial position, and the direction of the straight-line conversion guide rail is turned 90 degrees, so that the main sliding guide rail is disconnected and the lifting sliding guide rail is connected. Repeat step X1 until the transportation of all building module units is completed.

[0140] The construction method disclosed in this embodiment achieves efficient vertical lifting and horizontal transport of building module units through the coordinated operation of the sliding lifting frame and the sliding jig. The rotational switching of the linear conversion guide rail ensures the flexible connection and disconnection of the guide rail system, guaranteeing precise guidance of the transport path. Each step is executed cyclically, significantly improving the assembly efficiency and construction safety of large-span modular steel structures, and is suitable for the rapid construction needs of high-rise and ultra-large spatial structures.

[0141] Example 3

[0142] like Figure 16-21 As shown, this embodiment is basically the same as embodiment 1, except that the conversion guide rail 8 is a cross-shaped conversion guide rail 19;

[0143] The cross-shaped conversion guide rail 19 includes a first lifting guide rail 20, a second lifting guide rail 21, a third lifting guide rail 22, a fourth lifting guide rail 23, and a center guide rail 24;

[0144] The central guide rail 24 is located at the center of the first lifting guide rail 20, the second lifting guide rail 21, the third lifting guide rail 22 and the fourth lifting guide rail 23;

[0145] The first lifting guide rail 20, the second lifting guide rail 21, the third lifting guide rail 22 and the fourth lifting guide rail 23 are distributed sequentially around the central guide rail 24 at a 90-degree circumference.

[0146] The first lifting guide rail 20, the third lifting guide rail 22, and the center guide rail 24 connect the lifting sliding guide rail 4;

[0147] The second lifting guide rail 21, the fourth lifting guide rail 23, and the center guide rail 24 connect the main body sliding guide rail 3;

[0148] The first lifting guide rail 20, the second lifting guide rail 21, the third lifting guide rail 22, and the fourth lifting guide rail 23 are liftable structures. When the sliding lifting frame 5 passes the first lifting guide rail 20 and / or the third lifting guide rail 22, the second lifting guide rail 21 and / or the fourth lifting guide rail 23 descend to avoid obstructing the operation of the sliding lifting frame 5. When the sliding lifting frame 5 leaves the first lifting guide rail 20 and / or the third lifting guide rail 22, the second lifting guide rail 21 and / or the fourth lifting guide rail 23 rise to their original positions. When the sliding frame 6 passes the second lifting guide rail 21 and / or the fourth lifting guide rail 23, the first lifting guide rail 20 and / or the third lifting guide rail 22 descend to avoid obstructing the operation of the sliding frame 6. When the sliding frame 6 leaves the second lifting guide rail 21 and / or the fourth lifting guide rail 23, the first lifting guide rail 20 and / or the third lifting guide rail 22 rise to their original positions.

[0149] like Figures 19-20 As shown, as a further embodiment of this example, the first lifting guide rail 20, the second lifting guide rail 21, the third lifting guide rail 22 and the fourth lifting guide rail 23 have the same structure, each including a fixed base 25, a lifting rail 26, an elastic structure 27 and a lower pressure plate 28.

[0150] The fixed base 25 is fixedly connected to the central guide rail 24;

[0151] The lower end of the lifting rail 26 is connected to the elastic structure 27;

[0152] The end of the elastic structure 27 away from the lifting rail 26 is fixedly connected to the fixed base 25;

[0153] The lower pressure plate 28 is fixedly installed on the side wall of the lifting rail 26 near the center rail. When the opposite frame passes by, it contacts the lower pressure plate and presses the lifting rail 26 downward. The lifting rail 26 squeezes the elastic structure 27 and then descends to avoid the opposite frame.

[0154] In actual operation, the lower pressure plate 28 plays a crucial triggering role. Its precise positioning, at the appropriate height on the side wall of the lifting rail 26 near the central rail, ensures timely contact with the lower pressure plate when the opposite frame approaches. Upon contact, the lower pressure plate 28 transfers force to the lifting rail 26, subjecting it to downward pressure. The elastic structure 27 then utilizes its elastic properties, deforming under the pressure of the lifting rail 26, thereby lowering the lifting rail 26 to smoothly avoid the opposite frame, ensuring the smooth and stable operation of the entire device.

[0155] As a further embodiment of this example, one end of the lower pressure plate 28 is fixedly disposed on the side wall of the lifting rail 26, and the other end is an outwardly extended free end. The end is provided with a downward arc surface or inclined surface structure. When the frame comes into contact with the lower pressure plate 28 and continues to move, the downward arc surface or inclined surface structure of the lower pressure plate 28 slides into contact with the end of the frame and forces the lifting rail 26 to move downward.

[0156] As a further embodiment of this embodiment, a guide limiting groove 29 is provided in the fixed base 25;

[0157] The lower parts of the elastic structure 27 and the lifting rail 26 are disposed in the guide limiting groove 29;

[0158] The lifting rail 26 moves up and down along the guide limiting groove 29 during the lifting process.

[0159] like Figure 22 As shown, as a further embodiment of this example, the lower end of the lifting rail 26 is provided with an outwardly extending limiting plate 30, which is used to engage in the guide limiting groove 29 to limit the maximum height of the lifting rail 26, so that the height of the lifting rail 26 is the same as the height of the main sliding guide rail 3 and the lifting sliding guide rail 4 in the initial state.

[0160] As a further embodiment of this example, the elastic structure 27 is always in a compressed state and tends to push the lifting rail 26 upward.

[0161] During device operation, when the opposite frame is not approaching, the elastic structure 27, by virtue of its constant compression and tendency to lift the lifting rail 26 upwards, continuously applies an upward force to the lifting rail 26, ensuring that the lifting rail 26 remains stable at its initial height. At this time, the limiting plate 30 engages within the guide limiting groove 29, providing a stabilizing and restrictive function, ensuring that the lifting rail 26 does not move excessively upwards due to the force of the elastic structure 27. However, when the opposite frame approaches and contacts the lower pressure plate 28, the lower pressure plate 28 transmits its force to the lifting rail 26, subjecting it to downward pressure. The lifting rail 26 then moves downwards along the guide limiting groove 29, further compressing and deforming the elastic structure 27. During this process, the limiting plate 30 continues to move relative to the lifting rail within the guide limiting groove 29 until the action of avoiding the opposite frame is completed. After the opposite frame is moved away, the elastic structure 27 releases the compression energy, which lifts the lifting rail 26 upward again until the limit plate 30 is re-engaged in the corresponding position in the guide limit groove 29, so that the lifting rail 26 returns to its initial height and is at the same height as the main sliding guide rail 3 and the lifting sliding guide rail 4. This cycle is repeated to ensure that the entire device can operate stably and orderly under different working conditions.

[0162] As a further embodiment of this example, the lower end surfaces of the sliding jig 6 and the sliding lifting frame 5 are provided with clearance grooves 33 and pressing protrusions 34.

[0163] The clearance groove 33 is provided at the position corresponding to the lower pressure plate 28 on this side, and is used to avoid the lower pressure plate 28 on this side during the movement of the sliding frame 6 and the sliding lifting frame 5;

[0164] The top pressing protrusion 34 is positioned at the location of the lower pressing plate 28 on the opposite side, and is used to contact the lower pressing plate 28 on the opposite side and press down the lifting rail 26 on the opposite side when the sliding frame 6 and the sliding lifting frame 5 move.

[0165] By adopting the above technical solution, the present invention has the following beneficial effects:

[0166] (1) The cross-shaped conversion guide rail 19 is designed. Through the combination of the central guide rail 24 and four liftable lifting guide rails, the flexible connection and switching between the lifting sliding guide rail 4 and the main sliding guide rail 3 are realized, which effectively improves the track conversion efficiency during construction.

[0167] (2) The lifting characteristics of the four lifting guide rails enable the relevant guide rails to automatically descend and avoid obstruction when the sliding lifting frame 5 or the sliding frame 6 passes by, thus avoiding obstruction during the operation of the frame and ensuring the smooth progress of the construction process.

[0168] (3) The lifting guide rail is designed by combining the fixed seat 25, the lifting rail 26, the elastic structure 27 and the lower pressure plate 28, which not only ensures the stability of the guide rail, but also realizes the flexible lifting of the guide rail, providing reliable structural support for the construction process.

[0169] (4) The design of the cross-shaped conversion rail 19 reduces the risk of collision when the frame is running at the intersection, improves the safety of the construction process, and reduces the possibility of accidents.

[0170] (5) The automatic pressing and resetting mechanism of the elastic structure 27 and the lower pressure plate 28 realizes the automation of the guide rail lifting, reduces manual intervention, and improves construction efficiency.

[0171] Example 4

[0172] This embodiment provides a construction method suitable for large-span modular steel structures, including the following steps:

[0173] Y1: Transport the building module unit to the sliding lifting frame above the lifting platform, and the sliding lifting frame will raise the height of the building module unit;

[0174] Y2: The sliding lifting frame moves along the lifting sliding guide rail, the first lifting guide rail, the third lifting guide rail and the center guide rail and transports the raised building module unit to the top of the sliding frame. The sliding lifting frame lowers the height of the building module unit so that the building module unit is placed on the sliding frame and locked.

[0175] Y3: The sliding lifting frame moves in the reverse direction back to the initial position and receives the next building module unit;

[0176] Y4: The sliding frame moves along the main sliding guide rail, the second lifting guide rail, the fourth lifting guide rail and the central guide rail to move the building module unit above the large module support structure and place the building module unit on the large module support structure and fix it.

[0177] Y5: The sliding frame moves in the opposite direction back to the initial position, and step Y1 is repeated until all building module units are transported.

[0178] The construction method disclosed in this embodiment achieves efficient vertical lifting and horizontal transport of building module units through the coordinated operation of sliding lifting frames and sliding jigs, significantly improving the construction speed of large-span modular steel structures. Each lifting guide rail automatically adjusts its height under the action of elastic structures and lower pressure plates, ensuring a smooth transition of the frame, avoiding operational jamming, and reducing equipment wear and safety risks. The entire construction process does not require continuous operation of large hoisting equipment, saving costs and improving operational safety and precision control, making it suitable for rapid assembly of multi-story, multi-span steel structures under complex site conditions. This method, through a modular and streamlined operation mode, transforms traditional high-altitude assembly into a combination of ground or low-altitude pre-assembly and precise positioning, reducing the amount of high-altitude work and improving construction quality and personnel safety. The coordinated operation of each guide rail system under elastic reset and automatic avoidance mechanisms ensures the continuity and dynamic adaptability of the transport path, reflecting a high degree of integration between structural design and construction technology, and providing a replicable technical paradigm for modern intelligent construction.
