Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a cumulative sliding construction method for a steel structure grid shell structure. Background Technology

[0002] Cumulative sliding construction of steel grid shell structures is a highly efficient installation method that combines assembly and sliding in a cyclical manner. It involves setting up an assembly platform at one end of the building, dividing the structure into several units, assembling the first sliding unit, and then sliding it one unit's distance away, leaving some members for connection to the next unit. The second unit is then assembled on the platform and connected to the first, before sliding again; this process is repeated until all units accumulate into a complete structure, ultimately reaching the designed position. The biggest advantage of this method is its space-saving construction. It only requires a small assembly platform at the end, avoiding the need for full-scale scaffolding beneath the building, making it particularly suitable for complex sites with rivers, railways, or other ongoing operations below. Furthermore, most assembly and welding work is completed on the ground or a low-altitude platform, making quality control easier and allowing for parallel and overlapping operations with civil engineering and equipment installation, thus effectively shortening the overall construction period.

[0003] During construction, concrete and other debris easily adhere to the track. This adhesion causes the construction vehicle to sway as it moves along the track, which in turn causes the grid shell structure above it to shake. This can lead to positional changes in the grid shell structure, hindering subsequent installation. Furthermore, frequent and severe shaking can damage parts of the grid shell structure, affecting the strength of the final building. Therefore, this application proposes a cumulative sliding construction method for steel grid shell structures, which can detect and remove obstructions from the track. Summary of the Invention

[0004] The purpose of this invention is to provide a cumulative sliding construction method for steel structure grid shell structure to solve the problem mentioned in the background art that the track is prone to the adhesion of concrete and other debris during construction, and there is currently a lack of structure for detecting obstacles on the track. These adhered debris will cause the construction vehicle to shake when moving along the track.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cumulative sliding construction method for a steel structure reticulated shell structure, including a track and a construction vehicle. The bottom of the track is provided with a number of sleepers for support. The construction vehicle is located on the upper side of the track and is provided with a transport platform for storing the reticulated shell structure. The construction vehicle is equipped with a clamping unit, which includes a clamping plate and a telescopic rod connected to the clamping plate and installed on the construction vehicle. The construction vehicle is equipped with a support frame, a detection unit, and a slag removal unit. The detection unit is used to detect whether there are any obstructions on the track, and the slag removal unit is used to remove the obstructions on the track. The support frame is equipped with a lifting unit and a slag removal box connected to the lifting unit. The detection unit observes whether there are any obstructions on the track. If there are obstructions, the cleaning unit is activated to remove the obstructions from the track.

[0006] Preferably, the construction vehicle includes wheels, legs that rotate with the wheels, and a support frame for mounting the legs.

[0007] Preferably, the wheel cooperates with the track, the cross-section of the track is set in a T-shape, and a bearing shaft and a support seat that is inserted into the bearing shaft are provided at the middle position of the bearing frame.

[0008] Preferably, there are two clamping plates, and the two clamping plates are symmetrically distributed about the center line of the transport platform.

[0009] Preferably, the clamping plate has an L-shaped cross-section and is provided with a plurality of ribs for support, and a pressure plate is provided on the side of the clamping plate near the transport platform.

[0010] Preferably, a slider, a guide rail, and a pad are provided between the clamping plate and the construction vehicle. The slider is connected to the clamping plate, and the guide rail slides with the slider and is mounted on the construction vehicle.

[0011] Preferably, the pad is installed on the construction vehicle, and the upper end surface of the pad is in contact with the lower end surface of the guide rail.

[0012] Preferably, the detection unit includes a detection wheel, a detection frame that rotates and is rotatably mounted on a support frame and is rotatably coupled to the detection wheel, an elastic component installed between the detection wheel and the detection frame, and a detection mechanism.

[0013] Preferably, a limiting plate is provided at the detection frame, and the limiting plate is located on the lower side of the detection wheel.

[0014] Preferably, the support frame is provided with a slag cleaning bracket, and the inlet of the slag cleaning box is provided with an anti-backflow protrusion.

[0015] Beneficial effects: This invention provides a cumulative sliding construction method for a steel reticulated shell structure. An elastic component is located between the detection frame and the detection wheel. The elastic component provides thrust to the detection wheel, allowing it to press against the track without encountering external forces. The detection wheel and the detection frame rotate in coordination. When there is an obstruction on the track, the detection wheel rises along the obstruction. The detection mechanism in the detection unit checks the height of the detection frame. When the height changes, it indicates an obstruction on the track. At this point, the lifting unit is activated, which moves the cleaning box downwards. The cleaning box falls onto the track. During the movement of the construction vehicle, the obstructions on it enter the internal cavity of the cleaning box through its inlet, thus clearing the obstructions. This keeps the track clean and prevents significant swaying of the construction vehicle due to obstructions during movement, ensuring the stability of the reticulated shell structure during its movement.

[0016] This invention provides a cumulative sliding construction method for a steel reticulated shell structure. An extension rod is activated, which moves a clamping plate closer to or away from a transport platform. The reticulated shell structure is located on the transport platform. When the clamping plate approaches the platform, it clamps the reticulated shell structure, thus fixing its position and preventing displacement as the construction vehicle moves. The reticulated shell structure remains stable while moving along the track. Subsequent installation only requires moving the reticulated shell structure to the designated position; minimal changes to its forward or backward orientation are needed. This facilitates precise positioning during installation and reduces installation difficulty. Attached Figure Description

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1-5 As shown in the figure, the embodiment of the present invention provides a cumulative sliding construction method for a steel structure grid shell structure, including a steel structure grid shell structure cumulative sliding construction device. The device includes a track 1 and a construction vehicle 3. The bottom of the track 1 is provided with a plurality of sleepers 2 for support. The construction vehicle 3 is located on the upper side of the track 1 and is provided with a transport platform 4 for storing the grid shell structure.

[0021] For details, please refer to Figure 3 The construction vehicle 3 includes wheels 301, legs 302 that rotate with the wheels 301, and a support frame 303 for mounting the legs 302. The wheels 301 are fitted with the track 1. The cross-section of the track 1 is set in a T-shape. A support shaft 304 and a support seat 305 that are inserted into the support shaft 304 are provided at the middle position of the support frame 303.

[0022] During construction, the grid shell structure is placed on the construction vehicle 3 and moves with the displacement of the construction vehicle 3. The construction vehicle 3 has a power function and moves along the track 1, which can deliver the grid shell structure on it to the designated installation position. The main body of the grid shell structure is constructed of steel.

[0023] To secure the mesh structure and prevent it from shaking during transportation, a clamping unit 5 is installed on the construction vehicle 3. The clamping unit 5 includes a clamping plate 501 and a telescopic rod 504 connected to the clamping plate 501 and installed on the construction vehicle 3. The telescopic rod 504 can be a hydraulic cylinder. Correspondingly, the lifting unit 802 can also be a hydraulic cylinder or a pneumatic cylinder. There are two clamping plates 501, and the two clamping plates 501 are symmetrically distributed about the center line of the transport platform 4. The cross-section of the clamping plate 501 is L-shaped, and several ribs 502 for support are provided on the clamping plate 501. A pressure plate 503 is provided on the side of the clamping plate 501 closest to the transport platform 4.

[0024] In order to guide the movement of the clamping plate 501, a slider 505, a guide rail 506, and a pad 507 are provided between the clamping plate 501 and the construction vehicle 3. The slider 505 is connected to the clamping plate 501, the guide rail 506 is slidably engaged with the slider 505 and the guide rail 506 is mounted on the construction vehicle 3, and the pad 507 is mounted on the construction vehicle 3, with the upper end surface of the pad 507 in contact with the lower end surface of the guide rail 506.

[0025] When the telescopic rod 504 is activated, it can move the clamping plate 501 closer to or further away from the transport platform 4. The mesh shell structure is located on the transport platform 4. When the clamping plate 501 approaches the transport platform 4, it can clamp the mesh shell structure on it. This can fix the position of the mesh shell structure and prevent it from shifting as it moves with the construction vehicle 3. The mesh shell structure is stable as it moves along the track 1. During subsequent installation, it is only necessary to send the mesh shell structure to the designated position. The position in the front and back directions does not need to be changed too much. This facilitates the positioning during subsequent installation and reduces the difficulty of installation.

[0026] Place the reticulated shell structure on the transport platform 4, activate the clamping unit 5 to clamp the reticulated shell structure, and then activate the construction vehicle 3 to transport the reticulated shell structure to the designated location.

[0027] During construction, concrete and other debris easily adhere to track 1. This adhesion causes the construction vehicle 3 to sway as it moves along track 1. The swaying of the construction vehicle 3 causes the mesh shell structure on it to sway, which can easily lead to changes in the position of the mesh shell structure, making subsequent installation difficult. At the same time, frequent and violent shaking can easily damage parts of the mesh shell structure, affecting the strength of the building after installation. Therefore, the construction vehicle 3 is equipped with a support frame 6, a detection unit 7, and a debris removal unit 8. The detection unit 7 is used to detect whether there are any obstructions on track 1, and the debris removal unit 8 is used to remove the obstructions on track 1.

[0028] Specifically, such as Figure 4As shown, the detection unit 7 includes a detection wheel 701, a detection frame 702 rotatably mounted on the support frame 6 and rotatably engaged with the detection wheel 701, an elastic component installed between the detection wheel 701 and the detection frame 702, and a detection mechanism 703. The elastic component is located between the detection frame 702 and the detection wheel 701. The elastic component is used to provide a thrust to the detection wheel 701, allowing the detection wheel 701 to press against the track 1 without encountering external force. The detection wheel 701 and the detection frame 702 rotatably engage. When there is an obstruction on the track 1, the detection wheel 701 rises along the obstruction. The detection mechanism 703 in the detection unit 7 checks the height of the detection frame 702. When the height changes, it indicates that there is an obstruction on the track 1. The detection mechanism 703 can use a laser rangefinder to measure the distance between the support frame 6 and the detection frame 702. The distance change value is manually checked. When the change value is too high, it indicates that there is an obstruction on the track 1.

[0029] The elastic component can be a metal spring, with one end connected to the support frame 6 and the other end connected to the detection frame 702.

[0030] It should be noted that a limit plate 704 is provided at the detection frame 702. The limit plate 704 is located on the lower side of the detection wheel 701. The limit plate 704 is used to limit the maximum angle of the detection wheel 701 falling, so as to prevent the angle of the detection wheel 701 from being too low.

[0031] In order to clear the obstructions on track 1, a lifting unit 802 and a slag-cleaning box 803 connected to the lifting unit 802 are provided on the support frame 6. A slag-cleaning bracket 801 is provided on the support frame 6, and an anti-backflow protrusion 804 is provided at the inlet of the slag-cleaning box 803.

[0032] When the lifting unit 802 is activated, it can move the slag removal box 803 downward. The slag removal box 803 falls onto the track 1. During the movement of the construction vehicle 3, the obstructions on it enter the internal cavity of the slag removal box 803 through the inlet, thus achieving the cleaning of the obstructions. This keeps the track 1 clean and prevents the main body of the construction vehicle 3 from shaking significantly due to the obstructions during the movement, ensuring the stability of the mesh shell structure during the movement.

[0033] The detection unit 7 observes whether there are any obstructions on the track 1. If there are obstructions, the cleaning unit 8 is activated to remove the obstructions on the track 1. The activation of the cleaning unit 8 can be manually controlled.

[0034] In summary, this invention provides a cumulative sliding construction method for a steel reticulated shell structure. The telescopic rod 504 is activated, allowing the clamping plate 501 to move closer to or further away from the transport platform 4. The reticulated shell structure is located on the transport platform 4. When the clamping plate 501 approaches the transport platform 4, it clamps the reticulated shell structure, thus fixing its position and preventing it from shifting as the construction vehicle 3 moves. The reticulated shell structure remains stable as it moves along the track 1. During subsequent installation, only the reticulated shell structure needs to be moved to the designated position; its position in the forward and backward directions does not require significant changes. This facilitates accurate positioning during installation and reduces the difficulty of installation.

[0035] An elastic component is located between the detection frame 702 and the detection wheel 701. The elastic component provides a thrust to the detection wheel 701, allowing it to press against the track 1 without encountering external force. The detection wheel 701 and the detection frame 702 rotate in coordination. When there is an obstruction on the track 1, the detection wheel 701 rises along the obstruction. The detection mechanism 703 in the detection unit 7 checks the height of the detection frame 702. When the height changes, it indicates that there is an obstruction on the track 1. The detection mechanism 703 can use a laser rangefinder, which measures the distance between the support frame 6 and the detection frame 702. The distance between track 1 and track 2 is manually checked for changes. If the change is too high, it indicates that there is an obstruction on track 1. At this time, the lifting unit 802 is activated, which can drive the slag removal box 803 to move down. The slag removal box 803 falls onto track 1. During the movement of the construction vehicle 3, the obstructions on it enter the internal cavity of the slag removal box 803 through the entrance, thus achieving the cleaning of the obstructions. This keeps track 1 clean and prevents the main body of the construction vehicle 3 from shaking significantly due to obstructions during movement, ensuring the stability of the mesh shell structure during movement.

[0036] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
