Description

Technical Field

[0001] This invention relates to the technical field of space frame installation, and more specifically, to a steel structure roof installation mechanism and method. Background Technology

[0002] Steel space frame roofs are commonly found in large buildings. The space frame is typically assembled on the ground and then hoisted to the roof. In some complex environments, cranes cannot reach all parts of the building's roof, making the hoisting of some space frames difficult. Therefore, installation can also be done by horizontal movement. This involves installing tracks on the roof and assembling the space frame at one location; after assembly, the frame is moved horizontally along the tracks to the installation position to complete the installation. Generally, a full-span scaffold is erected on one side of the building to form an assembly platform. Once assembled, it can be moved horizontally. However, erecting a full-span scaffold requires a large amount of manpower and is time-consuming and labor-intensive. Summary of the Invention

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Example:

[0030] like Figures 1-7 As shown, this invention provides a steel structure roof installation mechanism, including an assembly mechanism 2 and a hoisting mechanism 1. The assembly mechanism 2 is located on the ground and is used for the rapid assembly of the space frame 27. The hoisting mechanism 1 is configured in conjunction with the assembly mechanism 2 so that the hoisting mechanism 1 can lift the space frame 27 assembled by the assembly mechanism 2 to the roof. The hoisting mechanism can be a common crane or a gantry crane, etc. For simplicity, a crane is used in this embodiment.

[0031] The assembly mechanism 2 includes several support bases 3. Each support base 3 has a placement groove 4 on its top. The placement groove 4 corresponds to a number of bolt balls 5, such that each placement groove 4 corresponds to one bolt ball 5.

[0032] The space frame 27 is assembled from bolted balls 5 and rods. The bolted balls 5 have several threaded holes on their outer surface, allowing the rods to be tightened into these holes, thus connecting the rods and bolted balls 5. The space frame 27 generally includes a double layer of bolted balls 5. Several bolted balls 5 are distributed in three-dimensional space and connected by several rods, thereby forming a three-dimensional spatial structure.

[0033] In use, the steel structure roof installation mechanism of this invention distributes and fixes the support bases 3 according to the distribution positions of the bottom bolt balls 5 of the space frame 27, so that each support base 3 corresponds to one bottom bolt ball 5. Then, the bottom bolt balls 5 are placed one by one into the placement grooves 4 on the top of the support bases 3, ensuring the bolt balls 5 are in their correct positions. The bolt balls 5 are then connected together using rods to form the bottom layer of the space frame 27. Bolt balls 5 and rods are then sequentially installed on top of the bottom layer of the space frame 27 to form the space frame 27 itself. Once the space frame 27 is assembled, it is lifted by the hoisting mechanism 1 and placed on the track 28 on the roof. Finally, the space frame 27 is moved to its installation position and fixed in place.

[0034] This steel structure roof installation mechanism assembles the space frame 27 on the ground, eliminating the need for high-altitude operations. Ground-based operations are also more efficient. Furthermore, this method eliminates the need for a full-span scaffold, significantly improving efficiency. In practice, the roof space frame 27 is quite large and cannot be hoisted as a whole. Therefore, the space frame 27 is assembled and hoisted in sections. After the space frame 27 is hoisted, new bolt balls 5 are simply placed in the placement slots 4 to assemble a new space frame 27, making the operation convenient.

[0035] In this embodiment, the support base 3 includes a lifting support base 6. The lifting support base 6 includes a base plate 7 and a telescopic mechanism disposed above the base plate 7. A placement slot 4 is disposed at the top of the telescopic mechanism.

[0036] Specifically, the telescopic mechanism includes a sleeve 8 and a telescopic rod 9. The sleeve 8 is vertically mounted on the upper surface of the base plate 7 and has internal threads. The telescopic rod 9 is threaded into the sleeve 8, allowing it to be rotated to raise or lower along the sleeve 8. This allows the height of the placement slots 4 to be adjusted. In actual construction, the site may be uneven. In this case, by adjusting the extension length of each telescopic mechanism, several placement slots 4 can be adjusted to the same height. This ensures that several bolt balls 5 are at the same horizontal height, further guaranteeing the assembly quality of the space frame 27.

[0037] To better secure the position of the lifting support 6 and prevent its displacement from affecting the assembly quality, the base plate 7 is provided with through holes. When the base plate 7 is placed on the ground, ground nails 26 are inserted into the through holes to fix the base plate 7 to the ground. The telescopic rod 9 is also fitted with a positioning nut 25. After the telescopic rod 9 is adjusted to its telescopic position, tightening the positioning nut 25 onto the sleeve 8 will prevent the telescopic rod 9 from rotating during use.

[0038] In this embodiment, the support base 3 further includes a movable support base 10. The movable support base 10 includes a base 11 and a lifting mechanism 12. The lifting mechanism 12 can be a hand-cranked jack. The lifting mechanism 12 can be raised and lowered by hand. The lifting mechanism 12 can also be a hydraulic cylinder. The top of the lifting mechanism 12 is provided with a connecting plate 13, and the bottom is provided with a universal ball 14. The top of the connecting plate 13 is also provided with a placement groove 4, and the side is provided with screw holes. The bottom of the lifting mechanism 12 is provided with a universal ball 14, so that the universal ball 14 can roll along the ground when supported on the ground, thereby facilitating the translation of the grid frame 27.

[0039] It also includes a frame mechanism 15. The frame mechanism 15 includes several movable support seats 10 and connecting rods 16. The connecting rods 16 are threaded and fit into the screw holes of the connecting plates 13. The several movable support seats 10 are distributed in a rectangular frame. Two adjacent connecting plates 13 are connected by the connecting rods 16, so that the several connecting plates 13 and the connecting rods 16 are connected to form a rectangular frame. Several lifting support seats 6 are distributed inside the rectangular frame. That is, the several movable support seats 10 distributed in a rectangular shape on the outside are connected into a whole by the connecting rods 16.

[0040] In use, several movable support seats 10 on the periphery support several bolt balls 5 on the periphery. Before assembling the space frame 27, the height of several movable support seats is adjusted to be the same as the height of several lifting support seats 6. This ensures that all bolt balls 5 are at the same height after being lowered. After the space frame 27 is assembled, the frame mechanism 15 is lifted, thereby lifting the space frame 27 as well. The space frame 27 is then lowered after being lifted above the roof. Since the top of the structural beam 24 has a pre-laid track 28, the lifting mechanism 12 is placed on the track 28, that is, the universal ball 14 is placed on the track 28. Then, the frame mechanism 15 is pushed to move along the track 28. After the space frame 27 is moved to the installation position, the lifting mechanism 12 is raised, thereby lifting the space frame 27. At this time, support points can be arranged below the installation point of the space frame 27. After the support points above the structural beam 24 are arranged, the lifting mechanism 12 is lowered, allowing the space frame 27 to be lowered to the support points and supported by the support points. Finally, the space frame 27 is secured to complete its installation. The lifting mechanism 12 continues to descend and detaches from the space frame 27. It then returns along the track 28 and is hoisted and placed on the base 11 for the next assembly of the space frame 27.

[0041] This allows the same frame mechanism 15 to be used for the assembly, hoisting, and translation of the space frame 27, avoiding frequent tooling changes and making the installation of the space frame 27 easier and more efficient. The omnidirectional ball joint 14 makes the translation of the space frame 27 easier. It also allows the space frame 27 to move in any direction, facilitating fine-tuning for positioning and further simplifying its installation.

[0042] In this embodiment, the base 11 is provided with a support platform 17. The support platform 17 is hollow, and its interior has an upward-opening receiving groove 18. The lifting mechanism 12 is provided with a positioning step 19, that is, the bottom of the lifting mechanism 12 is thinner and the top is thicker, thus forming a step shape. When the lifting mechanism 12 is placed on the support platform 17, the positioning step 19 is placed on the support platform 17 for support. The bottom end of the lifting mechanism 12 is received in the receiving groove 18. At this time, the lifting mechanism 12 is supported by the positioning step 19, while the bottom end of the lifting mechanism 12 is in a suspended state. This ensures that the positioning and support between the lifting mechanism 12 and the support platform 17 are both achieved through the positioning step 19, and both are fixed structures, which can better guarantee the effect of support and positioning. Conversely, if the universal ball 14 is used for support, the universal ball 14 may roll when subjected to external force, making it difficult to ensure the relative position of the entire frame mechanism 15 with respect to several lifting support platforms 17. This also makes it difficult to ensure the relative position between the bolt ball 5 placed on the top of the movable support and the bolt ball 5 placed on the top of the lifting support, thus making it difficult to ensure the assembly quality of the space frame 27.

[0043] To facilitate the placement of the bottom end of the lifting mechanism 12 into the receiving groove 18, the receiving groove 18 is designed in the shape of an upward-opening flared mouth. This also allows the lifting mechanism 12 to be guided by the groove wall of the receiving groove 18 during the lowering process, thereby making the fixed position of the lifting mechanism 12 after it is lowered more accurate and further ensuring the assembly quality of the space frame 27.

[0044] In this embodiment, ball bearings 20 are provided on the side of the bottom end of the lifting mechanism 12. In practice, the track 28 laid on the roof can be made of common channel steel. After the space frame 27 is lifted, the lifting mechanism 12 is placed in the channel of the channel steel to restrict the lifting mechanism 12. Under the restriction of the channel steel, the lifting mechanism 12 moves along the channel steel, thereby driving the space frame 27 to move along the channel steel to the installation position. When the ball bearings 20 provided on the side of the bottom end of the lifting mechanism 12 come into contact with the channel wall of the channel steel, friction between the lifting mechanism 12 and the channel wall of the channel steel is avoided, and the rolling of the ball bearings 20 can provide guidance.

[0045] In this embodiment, the frame mechanism 15 further includes several connectors 21. Each connector 21 has a screw hole that mates with a connecting rod 16, allowing the connecting rod 16 to be connected to the connector 21. Several connecting discs 13 and connectors 21 are connected by several connecting rods 16 to form a rectangular frame. The lower part of the connector 21 is spherically shaped to mate with the placement groove 4 of the lifting support 6, and the upper part also has a placement groove 4.

[0046] In practical use, the frame mechanism 15 only requires lifting mechanisms 12 on both sides of the track 28. The other two sides do not require lifting mechanisms 12; instead, a connecting device is sufficient to connect the two sides of the track 28 into a single unit. The frame mechanism 15 includes two opposing movable sides 23 and two opposing connecting sides 22. Each movable side 23 is equipped with a movable support seat 10. The connecting side 22 consists of a connecting rod 16 and a connecting piece 21. Furthermore, not every bolt ball 5 on both sides of the track 28 requires a lifting mechanism 12 for support. Therefore, the parts of the frame mechanism 15 that do not require lifting mechanism 12 support utilize the combination of lifting support seats 6 and connecting pieces 21. That is, the connecting piece 21 is placed in the placement slot 4 at the top of the lifting support frame. Simultaneously, the connecting rod 16 connects the connecting piece 21 and the connecting plate 13, thus forming a rectangular frame mechanism 15. When the frame mechanism 15 is lifted, only a small number of lifting mechanisms 12 are lifted simultaneously. The space frame 27 can be supported and moved using only a few lifting mechanisms 12. However, since the lifting mechanisms 12 require frequent raising and lowering to position the space frame 27 to the installation location, and each time it is placed on the ground, the placement slot 4 at its top needs to be at the same height as the placement slot 4 of the lifting support 6, the height of the lifting mechanism 12 needs to be fine-tuned after each raising and lowering. Reducing the number of lifting mechanisms 12 reduces the number of fine-tuning adjustments, thereby improving efficiency.

[0047] To better accommodate space frames 27 of different sizes, the length of the connecting rod 16 can be set as needed. This allows for adjustment of the distance between the support bases 3, and consequently, the distance between adjacent placement slots 4. This enables the adaptation to space frames 27 of different sizes.

[0048] This invention also provides a method for installing a steel structure roof, used in conjunction with the aforementioned steel structure roof installation mechanism. The installation method is as follows: A plurality of support seats 3 are positioned according to a plurality of bolt balls 5 at the bottom of the space frame 27, so that each support seat 3 corresponds to one bolt ball 5. A bolt ball 5 is placed on top of each support seat 3, and the bolt balls 5 are connected to form the space frame 27 by a plurality of rods. Then, the space frame 27 is lifted to the roof using a hoisting mechanism 1. Finally, the space frame 27 is moved to the installation position and fixed in place. This installation method eliminates the need to arrange cranes or other hoisting mechanisms 1 in various parts of the building for hoisting, and can adapt to building hoisting environments where crane placement is difficult.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
