Description

Technical Field

[0001] The present invention relates to the technical field of dome steel structures, in particular to an adjusting device for a circular dome steel structure. Background Art

[0002] A steel dome is an arched structure overlying a flat or curved surface. It is commonly used to construct the roof or dome portion of large buildings. Its characteristic is that its curved shape transfers loads to surrounding supporting structures, such as walls and columns, thereby supporting large vertical loads. Domes are often constructed of materials such as concrete, stone, steel, or wood, and possess excellent compressive resistance and stability.

[0003] Dome steel structures are widely used in architecture, often found in large public buildings such as religious buildings (such as churches), stadiums, and exhibition halls. They provide spacious interior spaces and beautiful exteriors. Furthermore, dome steel structures offer high overall stability and load-bearing capacity, effectively resisting horizontal loads such as wind and earthquakes.

[0004] In the prior art, when using steel structures to build hemispherical dome steel structure buildings, the steel structure needs to be divided into several micro units. The micro units are usually triangular, rectangular or hexagonal structures. However, the prior art lacks a mechanism for multiple position adjustments for the micro units. The method mainly involves cutting steel structure profiles of different lengths and then directly welding multiple profiles to keep the spliced steel structure in a hemispherical shape as much as possible. This construction method is difficult and requires a high level of professionalism from the staff, which is not conducive to popularization and use. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a circular dome steel structure adjustment device.

[0006] The above-mentioned technical objectives of the present invention are achieved through the following technical solutions: a circular dome steel structure adjustment device, including an adjustment mechanism, the adjustment mechanism including a jacking assembly and a connecting assembly arranged at the top of the jacking assembly, the connecting assembly including a connecting plate, a connecting column fixed to the top of the connecting plate, a universal joint movably connected to the top of the connecting column, and a connecting block fixed to the top of the universal joint, the top of the jacking assembly is connected to the bottom of the connecting plate, and a mounting assembly for mounting a steel structure profile is provided on the connecting block, the mounting assembly includes a mounting column arranged at the top of the connecting block, a lower plate body fixedly sleeved on the side wall of the mounting column near its bottom position, and an upper plate body sleeved on the mounting column and clearance-fitted, the bottom of the steel structure profile is connected to the top of the upper plate body, a horizontal adjustment assembly for adjusting the distance between two adjacent mounting columns is provided between two adjacent mounting columns, and a vertical adjustment assembly for adjusting the position of the mounting column is provided on the connecting plate.

[0007] By adopting the above technical solution, the staff can select steel structure profiles within a suitable length range according to the dimensional requirements of the circular dome steel structure. The distance between two adjacent mounting columns can be adjusted by using the horizontal adjustment component, and the position of the mounting column can be adjusted by using the vertical adjustment component, thereby adjusting the distance between two adjacent upper plate bodies, so that the distance between two adjacent mounting columns and the two upper plate bodies meets the installation requirements, changing the cumbersome operation of strictly cutting the steel structure profiles according to the dimensional requirements in the traditional technology, reducing the operation difficulty and the requirements for the professionalism of the staff, and being conducive to popularization and application.

[0008] Furthermore, screws that are in clearance fit with the upper plate body are arranged through the upper plate body, and the lower ends of the screws are threadedly connected to the top of the lower plate body. Upper annular chutes and lower annular chutes are respectively arranged at positions corresponding to the top of the lower plate body at the bottom of the upper plate body. The horizontal adjustment component includes a T-shaped slider that is slidably fitted with both the upper annular chute and the lower annular chute, a first connecting rod fixed to the side of the T-shaped slider away from the axis of the mounting column, a first connecting ball fixed to the end of the first connecting rod away from the T-shaped slider, a first hemispherical shell ball-jointed with the first connecting ball, a transverse screw rod fixed to the side of the first hemispherical shell away from the T-shaped slider, and a first threaded sleeve threadedly connected to the end of the transverse screw rod away from the first hemispherical shell. The extending direction of the T-shaped slider is an arc that is in fit with both the upper annular chute and the lower annular chute. The first threaded sleeve is located between two adjacent mounting columns. There are two sets of the T-shaped slider, the first connecting rod, the first connecting ball, the first hemispherical shell, and the transverse screw rod, and they are mirror-symmetrically distributed with respect to the first threaded sleeve.

[0009] By adopting the above technical solution, when the distance between two mounting columns needs to be adjusted, the staff only needs to rotate the first threaded sleeve. Since the first threaded sleeve is threadedly connected to two mirror-image transverse screw rods, the end of the transverse screw rod is fixed to the first hemispherical shell, and the first hemispherical shell is movably connected to the first connecting ball fixed to the first connecting rod, so that the two transverse screw rods approach or move away from each other, thereby controlling the two adjacent mounting columns to approach or move away from each other, so that the staff can adjust the position between the two mounting columns according to the dimensional setting requirements of the circular dome steel structure, and then install the steel structure profiles of a suitable length.

[0010] Further, the steel structure profile includes a first steel bar disposed between two adjacent mounting columns, a first arc-shaped profile fixed to one side of the first steel bar, a first supporting bar fixed to the other side of the first steel bar, a second steel bar located between two adjacent mounting columns and parallel to the first steel bar, a second arc-shaped profile fixed to the side of the second steel bar close to the first steel bar, and a second supporting bar fixed to the side of the second arc-shaped profile away from the first steel bar. The cross-sections of both the first arc-shaped profile and the second arc-shaped profile are arc-shaped. An arc-shaped clamping interface for clamping and cooperating with the first arc-shaped profile is provided on the side of the second arc-shaped profile away from the second steel bar. A clamping component for connecting with the transverse screw is provided on the steel structure profile.

[0011] Further, there are two sets of clamping components which are respectively connected to the transverse screws on both sides of the first threaded sleeve. The clamping component includes a first block fixed to both the bottom of the first steel bar and the bottom of the first supporting bar, a first clamping buckle fixed to the bottom of the first block, a second block fixed to both the bottom of the second steel bar and the bottom of the second supporting bar, and a second clamping buckle fixed to the bottom of the second block. Both the first clamping buckle and the second clamping buckle are buckled with the transverse screw.

[0012] By adopting the above technical solution, since the first clamping buckle and the second clamping buckle in the two sets of clamping components are both buckled with the transverse screw, the stability of the steel structure profile during the process of adjusting the two mounting columns by the horizontal adjusting component is ensured. A micro unit is composed of three steel structure profiles, and the circular dome steel structure is spliced by multiple micro units into a hemispherical structure. Multiple first supporting bars or second supporting bars in the micro unit play a good structural supporting role for the glass in the micro unit. After the glass and the first supporting bar as well as the second supporting bar are coated with sealant, it plays a good sealing and waterproofing role.

[0013] Further, a sliding rod is fixed to one end of the first arc-shaped profile, and an arc-shaped sliding groove for the sliding rod to slide and cooperate is provided at one end of the second arc-shaped profile. The cross-section of the connecting plate is circular plate-shaped. The vertical adjusting component includes an annular body cooperating with the connecting plate. Two clamping plates are fixed to the inner wall of the annular body. The sides of the two clamping plates close to each other are respectively attached to the top and the bottom of the connecting plate. The vertical adjusting component further includes a lower screw rod hinged to the top of the clamping plate, a second threaded sleeve hinged to the upper end of the lower screw rod, an upper screw rod threadedly connected to the upper end of the second threaded sleeve, a second hemispherical shell fixed to the upper end of the upper screw rod, a second connecting rod fixed to one side of the connecting block, and a second connecting ball fixed to the end of the second connecting rod away from the connecting block and cooperating with the second hemispherical shell.

[0014] By adopting the above technical solution, when the second threaded sleeve is turned, since the second threaded sleeve is threadedly connected to both the upper screw rod and the lower screw rod, the second hemispherical shell is movably connected to the second connecting ball, and the second connecting rod is fixed to both the second connecting ball and the connecting block, the upper screw rod and the lower screw rod are made to approach or move away from each other. Under the cooperative action of the universal joint, the inclination angle of the mounting column can be adjusted so that the staff can fine-tune the position of the mounting column at any time according to the installation requirements.

[0015] Furthermore, a fastening bolt is disposed through the top of the mounting column with a clearance fit therewith, and the lower end of the fastening bolt is fixed to the top of the connecting block. After the positions between adjacent mounting columns are adjusted according to the size requirements of the circular dome steel structure, the first arc-shaped profile and the second arc-shaped profile are welded together, and the mounting column is welded to the first arc-shaped profile, the second arc-shaped profile, the upper plate body, the first steel bar, and the second steel bar.

[0016] By adopting the above technical solution, after the staff completes the installation of the steel structure profiles within the smallest triangular unit, the adjusting mechanism can be integrally disassembled by unscrewing the fastening bolt for reuse. When the adjusting mechanism is required to act as a support for the circular dome steel structure, the fastening bolt can be tightened.

[0017] Furthermore, the cross-section of the first threaded sleeve is a regular hexagon, and cutting surfaces are provided on both sides of the second threaded sleeve.

[0018] By adopting the above technical solution, it is convenient for the staff to rotate the first threaded sleeve or the second threaded sleeve.

[0019] Furthermore, the jacking assembly includes a hydraulic jack and a jacking rod fixed to the upper end of the piston rod of the hydraulic jack, and the upper end of the jacking rod is fixed to the bottom of the connecting plate.

[0020] By adopting the above technical solution, during the installation of the steel structure profiles, the staff can finely adjust the hydraulic jack to make the adjusting mechanism adapt to the installation requirements of the steel structure profiles at different height positions.

[0021] Furthermore, multiple first supporting bars or second supporting bars located inside the same triangular unit are all on the same plane.

[0022] Furthermore, the first steel bar, the first arc-shaped profile, the first supporting bar, the second steel bar, the second arc-shaped profile, the second supporting bar, and the mounting column are all made of stainless steel.

[0023] By adopting the above technical solution, the probability that the first steel bar, the first arc-shaped profile, the first supporting bar, the second steel bar, the second arc-shaped profile, the second supporting bar, and the mounting column are rusted and the glass surface corresponding to their positions is rusted is reduced, which is beneficial to maintaining the aesthetics of the circular dome steel structure building.

[0024] In summary, the present invention has the following beneficial effects: 1. This application changes the cumbersome operation of strictly cutting steel structure profiles according to dimensional requirements in traditional technologies, reduces the operation difficulty and the requirements for the professionalism of staff, and is conducive to popularization and application; 2. In this application, when the distance between two mounting columns needs to be adjusted, the staff only needs to rotate the first threaded sleeve. Since the first threaded sleeve is threadedly connected to two mirror-image transverse screws, the end of the transverse screw is fixed to the first hemispherical shell, and the first hemispherical shell is movably connected to the first connecting ball fixed to the first connecting rod, so that the two transverse screws approach or move away from each other, thereby controlling the two adjacent mounting columns to approach or move away from each other, so that the staff can adjust the position between the two mounting columns according to the dimensional setting requirements of the circular dome steel structure, and then install the steel structure profile of a suitable length; 3. In this application, since the first buckle and the second buckle in the two groups of buckle assemblies are both buckled to the transverse screw, the stability of the steel structure profile during the process of adjusting the two mounting columns through the horizontal adjustment assembly is ensured. A micro unit is composed of three steel structure profiles, and the circular dome steel structure is spliced by multiple micro units into a hemispherical structure. Multiple first supporting bars or second supporting bars in the micro unit play a good structural supporting role for the glass in the micro unit. After the glass and the first supporting bar and the second supporting bar are coated with sealant, it plays a good sealing and waterproofing role. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] As Figure 1-11As shown in the figure, an adjusting device for a circular dome steel structure disclosed in an embodiment of the present application includes an adjusting mechanism 1. The adjusting mechanism 1 includes a jacking assembly 11 and a connecting assembly 12 disposed on the top of the jacking assembly 11. The connecting assembly 12 includes a connecting plate 121, a connecting column 122 fixed to the top of the connecting plate 121, a universal joint 123 movably connected to the top of the connecting column 122, and a connecting block 124 fixed to the top of the universal joint 123. The top of the jacking assembly 11 is connected to the bottom of the connecting plate 121. An installation assembly 2 for installing a steel structure profile 5 is disposed on the connecting block 124. The installation assembly 2 includes an installation column 21 disposed on the top of the connecting block 124, a lower plate body 22 fixedly sleeved on the side wall of the installation column 21 near its bottom, and an upper plate body 23 sleeved on the installation column 21 with a clearance fit. The bottom of the steel structure profile 5 is connected to the top of the upper plate body 23. A horizontal adjusting assembly 3 for adjusting the distance between two adjacent installation columns 21 is disposed between two adjacent installation columns 21. A vertical adjusting assembly 4 for adjusting the position of the installation column 21 is disposed on the connecting plate 121.

[0029] According to the size requirements of the circular dome steel structure, the staff selects a steel structure profile 5 within a suitable length range. By using the horizontal adjusting assembly 3, the distance between two adjacent installation columns 21 can be adjusted, and by using the vertical adjusting assembly 4, the position of the installation column 21 can be adjusted, thereby adjusting the distance between two adjacent upper plate bodies 23, so that the distance between two adjacent installation columns 21 and two upper plate bodies 23 meets the installation requirements, changing the cumbersome operation of strictly cutting the steel structure profile 5 according to the size requirements in the traditional technology, reducing the operation difficulty and the requirements for the professionalism of the staff, and being conducive to popularization and application.

[0030] A screw 231 that is in clearance fit with the upper plate body 23 is disposed through the upper plate body 23. The lower end of the screw 231 is threadedly connected to the top of the lower plate body 22. Upper annular chutes 221 and lower annular chutes 232 are respectively disposed at positions corresponding to the top of the lower plate body 22 at the bottom of the upper plate body 23. The horizontal adjusting assembly 3 includes a T-shaped slider 31 that is slidably engaged with both the upper annular chute 221 and the lower annular chute 232, a first connecting rod 32 fixed to the side of the T-shaped slider 31 away from the axis of the installation column 21, a first connecting ball 33 fixed to the end of the first connecting rod 32 away from the T-shaped slider 31, a first hemispherical shell 34 ball-jointed with the first connecting ball 33, a transverse screw 35 fixed to the side of the first hemispherical shell 34 away from the T-shaped slider 31, and a first threaded sleeve 36 threadedly connected to the end of the transverse screw 35 away from the first hemispherical shell 34. The extending direction of the T-shaped slider 31 is arc-shaped and is in fit with both the upper annular chute 221 and the lower annular chute 232. The first threaded sleeve 36 is located between two adjacent installation columns 21. Two sets of the T-shaped slider 31, the first connecting rod 32, the first connecting ball 33, the first hemispherical shell 34, and the transverse screw 35 are provided and are mirror-symmetrically distributed with respect to the first threaded sleeve 36.

[0031] When it is necessary to adjust the distance between the two mounting posts 21, the staff only needs to rotate the first threaded sleeve 36. Since the first threaded sleeve 36 is threadedly connected to the two mirror-image transverse screws 35, the end of the transverse screw 35 is fixed to the first hemispherical shell 34, and the first hemispherical shell 34 is movably connected to the first connecting ball 33 fixed to the first connecting rod 32. In this way, the two transverse screws 35 approach or move away from each other, thereby controlling the two adjacent mounting posts 21 to approach or move away from each other, so that the staff can adjust the position between the two mounting posts 21 according to the size setting requirements of the circular dome steel structure, and then install the steel structure profile 5 of the appropriate length.

[0032] The steel structure profile 5 includes a first steel bar 51 disposed between two adjacent mounting posts 21, a first arc-shaped profile 52 fixed to one side of the first steel bar 51, a first supporting bar 53 fixed to the other side of the first steel bar 51, a second steel bar 54 located between two adjacent mounting posts 21 and parallel to the first steel bar 51, a second arc-shaped profile 55 fixed to the side of the second steel bar 54 close to the first steel bar 51, and a second supporting bar 56 fixed to the side of the second arc-shaped profile 55 away from the first steel bar 51. The cross-sections of the first arc-shaped profile 52 and the second arc-shaped profile 55 are both arc-shaped. An arc-shaped clamping interface 551 for clamping and cooperating with the first arc-shaped profile 52 is provided on the side of the second arc-shaped profile 55 away from the second steel bar 54. A clamping component 6 for connecting with the transverse screw 35 is provided on the steel structure profile 5.

[0033] There are two groups of clamping components 6 and they are respectively connected to the transverse screws 35 on both sides of the first threaded sleeve 36. The clamping component 6 includes a first block 61 fixed to both the bottom of the first steel bar 51 and the bottom of the first supporting bar 53, a first clamping buckle 62 fixed to the bottom of the first block 61, a second block 63 fixed to both the bottom of the second steel bar 54 and the bottom of the second supporting bar 56, and a second clamping buckle 64 fixed to the bottom of the second block 63. Both the first clamping buckle 62 and the second clamping buckle 64 are buckled to the transverse screw 35.

[0034] Since the first clamping buckle 62 and the second clamping buckle 64 in the two groups of clamping components 6 are both buckled to the transverse screw 35, the stability of the steel structure profile 5 during the process of adjusting the two mounting posts 21 by the horizontal adjusting component 3 is ensured. A micro unit is composed of three steel structure profiles 5, and the circular dome steel structure is spliced by multiple micro units into a hemispherical structure. A plurality of first supporting bars 53 or second supporting bars 56 in the micro unit play a good structural supporting role for the glass in the micro unit. After the glass and the first supporting bar 53 and the second supporting bar 56 are coated with sealant, it plays a good sealing and waterproofing role.

[0035] One end of the first arc-shaped profile 52 is fixed with a sliding rod 521. One end of the second arc-shaped profile 55 is provided with an arc-shaped chute 552 for the sliding fit of the sliding rod 521. The cross-section of the connecting plate 121 is in the shape of a circular plate. The vertical adjustment assembly 4 includes a toroidal body 41 that cooperates with the connecting plate 121. Two clamping plates 411 are fixed to the inner wall of the toroidal body 41. One side of the two clamping plates 411 close to each other is respectively in contact with the top and the bottom of the connecting plate 121. The vertical adjustment assembly 4 further includes a lower screw rod 42 hinged to the top of the clamping plate 411, a second threaded sleeve 43 hinged to the upper end of the lower screw rod 42, an upper screw rod 44 threadedly connected to the upper end of the second threaded sleeve 43, a second hemispherical shell 45 fixed to the upper end of the upper screw rod 44, a second connecting rod 46 fixed to one side of the connecting block 124, and a second connecting ball 47 fixed to the end of the second connecting rod 46 away from the connecting block 124 and cooperating with the second hemispherical shell 45.

[0036] When the second threaded sleeve 43 is turned, since the second threaded sleeve 43 is threadedly connected to both the upper screw rod 44 and the lower screw rod 42, the second hemispherical shell 45 is movably connected to the second connecting ball 47, and the second connecting rod 46 is fixed to both the second connecting ball 47 and the connecting block 124, so that the upper screw rod 44 and the lower screw rod 42 approach or move away from each other. Under the cooperative action of the universal joint 123, the inclination angle of the mounting column 21 can be adjusted, so that the staff can finely adjust the position of the mounting column 21 at any time according to the installation requirements.

[0037] A fastening bolt 211 that is in clearance fit with the mounting column 21 is penetrated through the top of the mounting column 21. The lower end of the fastening bolt 211 is fixed to the top of the connecting block 124. After the positions between adjacent mounting columns 21 are adjusted according to the size requirements of the circular dome steel structure, the first arc-shaped profile 52 and the second arc-shaped profile 55 are welded together. The mounting column 21 is welded to the first arc-shaped profile 52, the second arc-shaped profile 55, the upper plate body 23, the first steel bar 51, and the second steel bar 54.

[0038] After the staff completes the installation of the steel structure profiles 5 within the smallest triangular unit, the fastening bolt 211 can be unscrewed to disassemble the adjustment mechanism 1 as a whole for reuse. When the adjustment mechanism 1 is required to act as a support for the circular dome steel structure, the fastening bolt 211 can be tightened.

[0039] To facilitate the staff to rotate the first threaded sleeve 36, the cross-section of the first threaded sleeve 36 is a regular hexagon. To facilitate the staff to rotate the second threaded sleeve 43, cutting surfaces are provided on both sides of the second threaded sleeve 43. The jacking assembly 11 includes a hydraulic jack 111 and a jacking rod 112 fixed to the upper end of the piston rod of the hydraulic jack 111. The upper end of the jacking rod 112 is fixed to the bottom of the connecting plate 121. During the installation of the steel structure profile 5, the staff can finely adjust the hydraulic jack 111 to make the adjusting mechanism 1 adapt to the installation requirements of the steel structure profile 5 at different height positions.

[0040] In this embodiment, multiple first supporting bars 53 or second supporting bars 56 located inside the same triangular unit are all on the same plane. The first steel bar 51, the first arc-shaped profile 52, the first supporting bar 53, the second steel bar 54, the second arc-shaped profile 55, the second supporting bar 56, and the mounting column 21 are all made of stainless steel. This reduces the probability that the first steel bar 51, the first arc-shaped profile 52, the first supporting bar 53, the second steel bar 54, the second arc-shaped profile 55, the second supporting bar 56, and the mounting column 21 rust and cause the glass surface corresponding to their positions to rust, which is beneficial to maintaining the aesthetics of the circular dome steel structure building.

All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
