Description
Technical Field
[0001] This invention relates to an openable and retractable roof design device, belonging to the field of building decoration structure technology. Background Technology
[0002] With the increasing demand for commercial facilities in urban renewal and older residential communities, adding billboards or signage to the flat roofs of existing low-rise and multi-story old buildings has become a common renovation method. These installations can generate advertising revenue and also help to unify and improve the overall appearance of buildings along the street.
[0003] However, rooftop billboard installations face significant wind resistance design challenges in practical applications. Billboards typically have a large wind-exposed area and bear substantial wind loads, especially in typhoon-prone coastal areas or northern regions with seasonal strong winds, where wind load often becomes the dominant factor controlling the structural design of the billboard. The traditional approach is to design a dense steel structure support system, including main columns, beams, diagonal braces, and a large-volume concrete counterweight foundation, rigidly fixing the entire billboard to the existing roof to resist extreme wind forces. This approach has the following significant shortcomings: First, most of the old buildings were built in the 1980s and 1990s, with low design load-bearing standards and obvious structural aging. Their roof structures are difficult to withstand the additional dead load and concentrated force transmitted by wind load from large steel billboards, resulting in prominent safety hazards.
[0004] Secondly, the steel structure support system itself is expensive and has a long construction period. It also requires drilling holes, installing reinforcing bars, or pouring concrete foundations on a large area of the existing roof, which causes significant disturbance to the waterproofing layer and structural integrity of the existing building. The renovation risks are high and the overall cost is high.
[0005] Third, once installed, the billboard becomes a permanent fixed structure. During non-windy seasons or periods of low wind speed, the structure remains in a "full-time wind-resistant" state, which not only wastes materials and space but also makes it impossible to flexibly adjust according to actual wind conditions.
[0006] Therefore, there is an urgent need to develop a roof design device that is lightweight, low-cost, easy to install quickly on existing roofs, and can automatically open and close according to wind conditions to actively and significantly unload wind loads, so as to effectively solve the technical problems of "load reduction and wind resistance" and "eliminating complex supporting steel structures" in the construction of rooftop billboards for old buildings; for this purpose, an openable roof design device is proposed. Summary of the Invention
[0007] In view of this, the present invention provides an openable roof design device to solve or alleviate the technical problem in the prior art of how to provide a roof design device for old buildings that is structurally lightweight, does not require complex steel structure support, and can automatically open and close according to wind conditions to actively unload wind loads, and at least provides a beneficial alternative.
[0008] The technical solution of this invention is implemented as follows: an openable roof design device, comprising a roof concrete frame, steel columns, design panels, and corner bracket components. The steel columns are symmetrically fixed on the roof concrete frame; The decorative panels are respectively installed on the two steel columns, and the two decorative panels are joined together in the closed state to form a complete roof decorative surface; The corner code assembly includes a first corner code, a second corner code, and a third corner code. One end of the first corner code and the third corner code are fixedly connected to the steel column, and one end of the second corner code is fixedly connected to the shaped signboard. The other end of the first, second, and third corner codes is provided with a torque adjustment component. The torque adjustment component is configured to allow the shaped signboard to rotate and open relative to the steel column to unload the wind load when the external wind load exceeds a preset threshold, and to automatically reset and close when the wind load decreases.
[0009] More preferably, the torque adjustment assembly includes a rotating shaft and a guide shaft. One end of the rotating shaft is threaded, and the other end is fixedly connected to a torque disk. The threaded end of the rotating shaft passes through the through holes on the second angle bracket and the first angle bracket in sequence, and is fixed by a second nut. The through hole of the second angle bracket is provided with a symmetrical positioning groove. The outer wall of the rotating shaft is provided with a positioning block that matches the positioning groove, and a bushing is provided in the through hole of the first angle bracket.
[0010] More preferably, a sliding sleeve is slidably sleeved on the guide shaft. The sliding sleeve and the torque disc are both provided with arc-shaped slopes on opposite sides and are staggered. The other end of the guide shaft is provided with a thread and is threadedly connected to a first nut. A washer and a spring are sequentially sleeved on the side of the first nut near the sliding sleeve. The two ends of the spring abut against the sliding sleeve and the washer, respectively. The threaded end of the guide shaft is fixedly provided with a shoulder, one end of which passes through the through hole on the third angle bracket and is fixed by the third nut.
[0011] More preferably, a central guide post is coaxially disposed at one end of the guide shaft near the rotating shaft, and a central guide hole coaxial with the rotating shaft is opened in the torque disk, and the central guide post is inserted into the central guide hole and can rotate relative to it.
[0012] More preferably, the sliding sleeve has a sliding cavity, the inner wall of the sliding cavity has a guide groove, and the guide shaft is provided with a guide key that matches the guide groove. The guide key is slidably disposed on the inner side wall of the guide groove.
[0013] More preferably, the two steel columns and the two decorative plaques constitute a set of decorative units, and multiple sets of decorative units are arranged at horizontal intervals on the roof concrete frame.
[0014] In a further preferred embodiment, a embedded plate is welded to the bottom of the steel column, and an anchoring steel plate is pre-embedded in the roof concrete frame. Bolts are welded to the anchoring steel plate, and the embedded plate is fixedly connected to the bolts by tightening nuts.
[0015] Preferably, the springs in the multiple sets of the design units have the same elastic coefficient, so that the design panels in each set open synchronously under the same wind pressure level.
[0016] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: This invention achieves a lightweight installation structure by setting symmetrical steel columns and decorative panels on a roof concrete frame, and incorporating a torque adjustment component between the steel columns and the decorative panels. The preload of the spring in the torque adjustment component is set so that when the overturning moment generated by the wind load exceeds the frictional torque transmitted by the spring through the curved slope, the decorative panel automatically rotates around its axis and opens, allowing wind to flow through the opening and reducing the wind load. When the wind load decreases, the spring's rebound force drives the sliding sleeve to reset, and the curved slope causes the decorative panel to return to its closed state, thus achieving active adaptive adjustment based on wind conditions.

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0030] like Figure 1-7 As shown, this embodiment of the invention provides an openable roof design device, including a roof concrete frame 1, steel columns 2, a design panel 3, and corner bracket components 4. The steel columns 2 are symmetrically fixed on the roof concrete frame 1; The decorative panels 3 are respectively set on the two steel columns 2, and the two decorative panels 3 are joined together in the closed state to form a complete roof decorative surface; The corner code component 4 includes a first corner code 40, a second corner code 41 and a third corner code 42. One end of the first corner code 40 and the third corner code 42 are fixedly connected to the steel column 2, and one end of the second corner code 41 is fixedly connected to the shaped signboard 3. The other end of the first corner code 40, the second corner code 41 and the third corner code 42 is provided with a torque adjustment component 5. The torque adjustment component 5 is configured to allow the shaped signboard 3 to rotate and open relative to the steel column 2 to unload the wind load when the external wind load exceeds a preset threshold, and to automatically reset and close when the wind load decreases.
[0031] By setting the preload of the spring 53 in the torque adjustment component 5, when the overturning moment generated by the wind load exceeds the frictional torque transmitted by the spring 53 through the arc slope 503, the shaped signboard 3 automatically rotates around the rotating shaft 50 to open, allowing wind to flow through the opening and reducing the wind load; when the wind load decreases, the rebound force of the spring 53 drives the sliding sleeve 52 to reset, and the shaped signboard 3 returns to the closed state through the arc slope 503, realizing active adaptive adjustment according to wind conditions.
[0032] In one embodiment, the torque adjustment assembly 5 includes a rotating shaft 50 and a guide shaft 51. One end of the rotating shaft 50 is threaded, and the other end is fixedly connected to a torque disk 501. The threaded end of the rotating shaft 50 passes through the through holes on the second angle bracket 41 and the first angle bracket 40 in sequence, and is fixed by the second nut 56. The through hole of the second angle bracket 41 is provided with a symmetrical positioning groove 43. The outer wall of the rotating shaft 50 is provided with a positioning block 504 that matches the positioning groove 43, and a bushing is provided in the through hole of the first angle bracket 40.
[0033] In this embodiment, refer to Figure 5 and Figure 7 The threaded end of the rotating shaft 50 is passed through the second angle bracket 41, and the positioning block 504 is aligned with the positioning groove 43 and inserted. After passing through the through hole on the first angle bracket 40, one side of the torque disk 501 can abut against the second angle bracket 41 and be locked by the second nut 56. This allows the shaped plate 3 and the second angle bracket 41 to rotate relative to the first angle bracket 40 and the steel column 2 via the rotating shaft 50. The cooperation between the positioning block 504 and the positioning groove 43 allows the shaped plate 3 to drive the second angle bracket 41, the rotating shaft 50 and the torque disk 501 to rotate relative to the first angle bracket 40, i.e. the steel column 2, when subjected to the power of external wind load. At the same time, in order to facilitate the rotation of the rotating shaft 50, a bushing is provided on the through hole of the first angle bracket 40.
[0034] In one embodiment, a sliding sleeve 52 is slidably sleeved on the guide shaft 51. The sliding sleeve 52 and the torque disk 501 are both provided with arc-shaped slopes 503 on opposite sides and are staggered. The other end of the guide shaft 51 is provided with a thread and is threadedly connected to a first nut 55. A washer 54 and a spring 53 are sequentially sleeved on the side of the first nut 55 near the sliding sleeve 52. The two ends of the spring 53 abut against the sliding sleeve 52 and the washer 54, respectively. A shoulder 511 is fixedly provided on the threaded end of the guide shaft 51. One end of the shoulder passes through the through hole on the third angle bracket 42 and is fixed by the third nut 57.
[0035] In this embodiment, see Figures 5-6The guide shaft 51 is fixed to the third angle bracket 42 via the shoulder 511 at its threaded end and the third nut 57. The third angle bracket 42 is fixed to the steel column 2. Through the elastic force of the spring 53, the sliding sleeve 52 can be pressed against the torque disk 501. The arc slope 503 makes the torque disk 501 and the sliding sleeve 52 close alternately. With the first angle bracket 40 and the third angle bracket 42 simultaneously fixing the steel column 2, the distance of the first nut 55 on the guide shaft 51 can be adjusted by using a wrench to adjust the extension and contraction of the spring 53, that is, to adjust the tension of the spring 53. The tension drives the sliding sleeve 52 to close with the torque disk 501. When the external wind load drives the rotating shaft 50 to rotate, it is converted into the torque disk 501 on the rotating shaft 50 relative to the sliding sleeve 501. When the external wind load is greater than the torque force of the torque disk 501 relative to the sliding sleeve 52, the rotating shaft 50 rotates within the first bracket 40, causing the torque disk 501 to rotate synchronously. This, in turn, pushes the sliding sleeve 52 to slide on the guide shaft 51 under the action of the arc slope 503, and further compresses the spring 53. At this time, the two shaped plates 3 change from a closed state to an open state, unloading the excessive external wind load. When the external wind load is less than the torque force of the torque disk 501 relative to the sliding sleeve 52, the sliding sleeve 52 is driven to move towards the torque disk 501 under the rebound force of the spring 53. Under the action of the arc slope 503, the rotating shaft 50 is driven to return to its initial position, and the two shaped plates 3 close normally.
[0036] In addition, Figure 5 and Figure 6 As shown, there are multiple arc-shaped slopes 503, or they can be set as one or arranged symmetrically, so that the torque disk 501 and the sliding sleeve 52 can be closed normally, and the arc-shaped slope 503 on the torque disk 501 can slide relative to the arc-shaped slope 503 of the sliding sleeve 52 and drive the sliding sleeve 52 to move relative to the guide shaft 51.
[0037] In one embodiment, a central guide post 513 is coaxially disposed at one end of the guide shaft 51 near the rotating shaft 50. A central guide hole 502 coaxial with the rotating shaft 50 is formed in the torque disk 501. The central guide post 513 is inserted into the central guide hole 502 and can rotate relative to it. The central guide hole 502 and the central guide post 513 are coaxially disposed to ensure the stability of the rotating shaft 50 when rotating relative to the sliding sleeve 52.
[0038] The sliding sleeve 52 has a sliding cavity 521, and a guide groove 522 is formed on the inner wall of the sliding cavity 521. A guide key 512 adapted to the guide groove 522 is provided on the guide shaft 51, and the guide key 512 is slidably disposed on the inner side wall of the guide groove 522. The sliding cavity 521 allows the sliding sleeve 52 to be movably sleeved on the guide shaft 51. By providing the guide key 512 and the guide groove 522, the axial sliding of the sliding sleeve 52 relative to the guide shaft 51 can be restricted, thereby compressing the spring 53 when the sliding sleeve 52 is displaced relative to the guide shaft 51.
[0039] To accommodate the size of the billboards mounted on the roof concrete frame 1, two steel columns 2 and two decorative signboards 3 form a decorative unit. Multiple decorative units are spaced horizontally along the roof concrete frame 1. For example... Figure 2 As shown, when subjected to a positive wind load, the two decorative panels 3 are driven to open inwards towards the steel column 2, releasing the excessive wind load. Figure 3 As shown, when subjected to a reverse wind load, the two shaped panels 3 are driven to open outwards towards the steel column 2, releasing the excessive wind load.
[0040] To facilitate the fixing of the steel column 2 to the roof concrete frame 1, an embedded plate 10 is welded to the bottom of the steel column 2. Anchor steel plates are pre-embedded in the roof concrete frame 1, and bolts are welded to the anchor steel plates. The embedded plate 10 is fixed to the bolts by tightening nuts. (Not shown in the figure; setting pre-embedded parts in the roof and walls is a conventional technical solution and will not be described further here.) The springs 53 in the multiple sets of decorative units have the same elastic coefficient, allowing the decorative panels 3 of each set to open synchronously under the same wind pressure level.
[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
