Abstract
Description
Technical Field
[0001] This utility model relates to the field of building structure technology, and in particular to a support mechanism and roof structure. Background Technology
[0002] Tensioned monolithic cable-stayed structures are lightweight spatial structure systems that use pretension to create a self-balancing and stable structure between ropes and cables. Large-span roof structures refer to roof structure systems with a span of 60 meters or more. During construction, the large-span roof structure covers the frame formed by the tensioned monolithic cable-stayed structures.
[0003] However, existing large-span roof structures, lacking auxiliary support mechanisms beneath the roof, are prone to collapse if their load-bearing capacity is insufficient, resulting in cost losses and, in severe cases, personal injury or death. To address this support issue, patent CN219386823U discloses a roof support mechanism including a lead screw and a handwheel. The lead screw passes through a crossbeam of the roof structure, and rotating the handwheel causes the lead screw to rotate, moving a connecting plate at the top of the lead screw up and down. However, the presence of a lead screw through-hole in the crossbeam affects the overall structural stability and also impacts the stability of the support mechanism itself. Therefore, a support mechanism and roof structure are urgently needed to solve the aforementioned technical problems. Utility Model Content
[0004] The purpose of this utility model is to provide a support mechanism and roof structure to solve the problems existing in the prior art, so that the main body of the roof can be well supported and has good stability.
[0005] To achieve the above objectives, this utility model provides the following solution:
[0006] This utility model provides a support mechanism, including a vertical plate, a support plate, and an adjustment mechanism. The vertical plate is fixedly connected to the crossbeam of the roof. A receiving groove is provided on the vertical plate. The adjustment mechanism includes a lead screw, a nut, and a fixing member. The top of the lead screw is fixedly connected to the support plate. The support plate is used to fit against the roof body. The bottom of the lead screw is fixedly connected to the fixing member and is located inside the vertical plate. The fixing member is axially sliding and circumferentially fixed relative to the vertical plate. The nut is threadedly connected to the lead screw and is located in the receiving groove. The top surface of the nut can fit against the top surface of the receiving groove, and the bottom surface of the nut can fit against the bottom surface of the receiving groove.
[0007] In some embodiments, a receiving cavity is provided inside the vertical plate along the height direction, and the lead screw is located inside the receiving cavity.
[0008] In some embodiments, the fixing member is a guide block, which is fixedly connected to the bottom of the lead screw. The outer wall of the guide block is fitted against the inner wall of the receiving cavity, and the guide block can slide within the receiving cavity.
[0009] In some embodiments, the lead screw is a trapezoidal lead screw.
[0010] In some embodiments, a turntable is also included, which is fixedly sleeved on the outer periphery of the nut.
[0011] In some embodiments, the cavity has a hexagonal cross-section, the guide block is an external hexagonal nut, and the outer edge of the external hexagonal nut can fit against the inner wall of the cavity.
[0012] This utility model also provides a roof structure, including a crossbeam, a roof body, and a support mechanism as described above. The crossbeam is fixedly connected to the roof body, and the support mechanism is disposed on the crossbeam.
[0013] In some embodiments, the two ends of the crossbeam are fixedly connected to the roof body by expansion bolts.
[0014] In some embodiments, a cover assembly is also included, which includes a waterproof layer, an anti-corrosion layer, a noise reduction layer, a heat storage layer and a buffer layer arranged and fixedly connected from top to bottom.
[0015] In some embodiments, the roof body is an arc-shaped structure, the support plate is an arc-shaped panel, the arc of the support plate is the same as the arc of the roof body, and the top surface of the support plate can fit against the bottom surface of the roof body.
[0016] The present invention achieves the following technical advantages over the prior art:
[0017] The vertical plate of the support mechanism provided by this utility model is directly fixed to the horizontal beam. The lead screw does not need to move back and forth within the horizontal beam, and there are no holes on the horizontal beam through which the lead screw passes, thus ensuring high strength without weakening the mechanism itself. Furthermore, if holes were provided on the horizontal beam through which the lead screw passes, the lead screw's contact function would fail once the holes wear down over time. In this utility model, the vertical plate is fixedly connected to the horizontal beam, and the adjustment mechanism is located on the vertical plate. The positional constraint of the adjustment mechanism is provided by the vertical plate, ensuring the stability of the adjustment mechanism itself. Moreover, after the roof body is installed, the height of the support plate can be adjusted via the adjustment mechanism simply by turning the nut, facilitating the adjustment of the support plate to the appropriate position. Using the support mechanism of this utility model to support the roof body ensures good stability and prevents direct collapse. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] The purpose of this utility model is to provide a support mechanism and roof structure to solve the problems existing in the prior art, so that the main body of the roof can be well supported and has good stability.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Example 1
[0029] like Figures 1-5 As shown, this utility model provides a support mechanism 2, including a vertical plate 23, a support plate 26, and an adjustment mechanism. The vertical plate 23 is used to fix and connect to the roof beam 21, preferably by welding. The vertical plate 23 has a receiving groove 29. The adjustment mechanism includes a lead screw 24, a nut 27, and a fixing member. The top of the lead screw 24 is fixedly connected to the support plate 26. The support plate 26 is used to fit against the roof body 1. The bottom of the lead screw 24 is fixedly connected to the fixing member and located inside the vertical plate 23. The fixing member is circumferentially fixed relative to the vertical plate by sliding axially. The nut 27 is threadedly connected to the lead screw 24 and is located in the receiving groove 29. The receiving groove 29 penetrates the vertical plate 23. The top surface of the nut 27 can fit against the top surface of the receiving groove 29, and the bottom surface of the nut 27 can fit against the bottom surface of the receiving groove 29. The nut can be turned by the operator. Preferably, the nut can protrude from the receiving groove. The vertical plate 23 is directly fixed to the horizontal beam 21, eliminating the need for the lead screw 24 to move back and forth within the beam 21. Since there are no holes for the lead screw 24 to pass through the beam 21, it remains undamaged, ensuring high strength. Furthermore, if holes for the lead screw 24 were provided in the beam 21, the lead screw 24 would fail to provide contact once the holes wear down over time. In this embodiment, the vertical plate 23 is fixedly connected to the horizontal beam 21, and the adjustment mechanism is mounted on the vertical plate 23. The positional constraint of the adjustment mechanism is provided by the vertical plate 23, ensuring its stability. After the roof body is installed, the height of the support plate 26 can be adjusted via the adjustment mechanism simply by turning the nut 27, facilitating the adjustment of the support plate 26 to the appropriate position. Using the support mechanism 2 of this embodiment to support the roof body 1 ensures good stability and prevents direct collapse.
[0030] In some embodiments, a receiving cavity 210 is provided within the vertical plate 23 along the height direction, and the lead screw 24 is located within the receiving cavity 210. The receiving cavity 210 encloses the lead screw 24, effectively preventing external dust, rainwater, debris, etc., from corroding and contaminating the lead screw 24, reducing the risk of failure due to rust or jamming, extending the service life of the lead screw 24, and ensuring the long-term reliability of the adjustment function. At the same time, the receiving cavity 210 prevents the lead screw 24 from being directly exposed to the outside and subjected to external force damage such as collision and friction, providing physical protection for the lead screw 24 and maintaining its structural integrity.
[0031] In some embodiments, the support mechanism 2 further includes a guide block 25, which is fixedly connected to the bottom of the lead screw 24. The outer wall of the guide block 25 is fitted against the inner wall of the receiving cavity 210, and the guide block 25 can slide within the receiving cavity 210. The fit between the outer wall of the guide block 25 and the inner wall of the receiving cavity 210 provides precise guidance and constraint for the lifting and lowering movement of the lead screw 24, effectively limiting the lateral sway or rotational deviation of the lead screw 24 during its up-and-down movement, and also preventing wear of the lead screw 24 during adjustment. Compared to relying solely on the threaded engagement between the lead screw 24 and the nut 27 for positioning, the presence of the guide block 25 makes the movement trajectory of the lead screw 24 more stable, ensuring that the support plate 26 always rises and falls smoothly in the vertical direction, and preventing uneven force distribution or support failure of the roof body 1 due to the tilt of the lead screw 24.
[0032] In some embodiments, the lead screw 24 is a trapezoidal lead screw. The thread profile of the trapezoidal lead screw is trapezoidal, with a thread angle typically around 30°. Compared to ordinary triangular threads, its thread cross-sectional area is larger, its root strength is higher, and it can withstand greater axial loads. The roof body 1 itself has a certain weight, and the support mechanism 2 needs to withstand the pressure of the roof for a long time. The high strength characteristics of the trapezoidal lead screw ensure that it is not prone to thread deformation or breakage under long-term heavy loads, ensuring the stability of the support. The trapezoidal thread has a small helix angle and a large frictional force between the thread surfaces, enabling reliable self-locking under axial loads (i.e., the lead screw 24 and nut 27 will not rotate relative to each other due to the load). When the support plate 26 is adjusted to a suitable height via the adjustment mechanism, the self-locking performance of the trapezoidal lead screw, combined with the limiting position of the nut 27 by the receiving groove 29, prevents the nut 27 from accidentally loosening or sliding due to the pressure or vibration of the roof body 1, ensuring the stability of the support plate 26's height and preventing roof settlement or displacement.
[0033] In some embodiments, the support mechanism 2 further includes a turntable 28, which is fixedly sleeved on the outer periphery of the nut 27. The turntable 28 provides a larger gripping or force-applying area, allowing the operator to directly hold and rotate the turntable 28 without relying on auxiliary tools such as wrenches (or with the aid of tools for more stable force application), making operation more flexible. The presence of the turntable 28 shifts the force application point to its own outer periphery, and its surface can be designed with anti-slip textures (such as knurling), which increases friction to prevent slippage and avoids direct contact between the operator and the nut 27, improving operational safety while reducing wear on the surface of the nut 27.
[0034] In some embodiments, the receiving cavity 210 has a hexagonal cross-section, and the guide block 25 is an external hexagonal nut 27. The outer edge of the external hexagonal nut 27 can fit against the inner wall of the receiving cavity 210. The shape of the hexagonal cross-section of the receiving cavity 210 and the external hexagonal nut 27 are perfectly matched. After they fit together, they form a rigid constraint, which can strictly limit the circumferential rotation of the guide block 25 (external hexagonal nut 27) in the receiving cavity 210. This ensures that the guide block 25 can only slide vertically along the height direction of the receiving cavity 210, and will not rotate synchronously with the rotation of the lead screw 24 or the nut 27. This avoids problems such as lead screw 24 offset and adjustment jamming caused by the rotation of the guide block 25, and ensures the directional accuracy of the height adjustment of the support plate 26.
[0035] Example 2
[0036] like Figures 1-5 As shown, this embodiment provides a roof structure, including a horizontal beam 21, a roof body 1, and a support mechanism 2 as described in Embodiment 1. The horizontal beam 21 is fixedly connected to the roof body 1, the support mechanism 2 is mounted on the horizontal beam 21, and vertical plates 23 are welded to the horizontal beam 21, or the vertical plates 23 and the horizontal beam 21 are integrally cast. With the support of the support mechanism 2, the roof body will not collapse directly, exhibiting high stability. It should be noted that the roof body of this utility model is designed for large-span roof structures, which have a greater risk of collapse than ordinary roof structures.
[0037] In some embodiments, the two ends of the crossbeam 21 are fixedly connected to the roof body 1 by expansion bolts 22. The working principle of the expansion bolts 22 is that tightening the bolts causes the expansion sleeve to expand and tightly engage with the inner wall of the connected component (here, the mounting hole of the roof body 1), forming a strong frictional force and mechanical locking force. This effectively transfers the load borne by the crossbeam 21 (such as the weight of the roof body 1, external wind force, etc.) to the roof body 1, ensuring that there is no relative displacement or loosening between the crossbeam 21 and the roof body 1, and providing a stable foundation connection for the support mechanism 2.
[0038] In some embodiments, the roof structure further includes a cover assembly 3, which includes a waterproof layer 31, an anti-corrosion layer 32, a noise reduction layer 33, a heat storage layer 34, and a buffer layer 35, arranged sequentially from top to bottom and fixedly connected. The waterproof layer 31 serves to waterproof the roof, preventing rainwater from seeping into the large-span roof body 1 and avoiding problems such as mold, structural corrosion (e.g., in metal roofs), or concrete weathering caused by long-term dampness. This reduces water damage to the roof from the source. The anti-corrosion layer 32 provides corrosion protection, preventing acid rain and other solutions from seeping into the large-span roof body 1 under severe weather conditions. The anti-corrosion layer 32 specifically resists the erosion of corrosive media such as acid rain and industrial exhaust gases. Especially in rainy or industrial environments, it effectively protects the material properties of the roof body 1, delays structural aging, and significantly extends the overall service life of the roof. The noise reduction layer 33 reduces noise, offsetting rain noise and wind howling, thus optimizing the indoor acoustic environment. The heat storage layer 34 serves to store heat, absorbing heat during the day and releasing heat at night, which can regulate indoor temperature fluctuations to a certain extent. In summer, it can reduce the rapid transfer of heat into the room, and in winter, it can slowly release the stored heat to help maintain a suitable indoor temperature, reduce the energy consumption of air conditioning and other equipment, and achieve energy-saving effects. The buffer layer 35 serves to buffer and reduce the impact of heavy rainfall on the large-span roof body 1. The buffer layer 35 is located at the bottom of the cover component 3 and is in direct contact with the roof body 1. When encountering heavy rainfall, hail and other weather, it can absorb impact energy through its own elasticity or toughness, reduce the direct impact of raindrops and hail on the roof body 1, and reduce damage such as cracks and deformation of the roof caused by long-term impact.
[0039] In some embodiments, the main body of the roof is an arc-shaped structure, and the support plate 26 is an arc-shaped panel. The arc of the support plate 26 is the same as that of the main body of the roof, and the top surface of the support plate 26 can fit against the bottom surface of the main body of the roof. The tightly fitted structure enables surface contact between the support plate 26 and the main body of the roof, which can reduce the relative displacement or vibration caused by gaps between the two, reduce the risk of loosening of the connection parts, and effectively transfer loads, especially when subjected to external forces such as wind and earthquakes, ensuring the stability of the overall structure.
[0040] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
