Description

Technical Field

[0001] This invention relates to the field of dome steel structure technology, and in particular to an adjustment device for a circular dome steel structure. Background Technology

[0002] A dome steel structure is an arched structure covering a flat or curved surface, typically used to construct the top or dome portion of large buildings. Its characteristic feature is the transfer of loads to the surrounding supporting structures, such as walls and columns, through its curved shape, thus enabling it to withstand significant vertical loads. Dome structures are often constructed using materials such as concrete, stone, steel, or wood, possessing excellent compressive strength and stability.

[0003] Steel dome structures are widely used in architecture, commonly found in religious buildings (such as churches), stadiums, exhibition halls, and other large public buildings, to provide spacious interiors and aesthetically pleasing appearances. Furthermore, steel dome structures possess high overall stability and load-bearing capacity, effectively resisting horizontal loads such as wind and earthquakes.

[0004] In existing technologies, when constructing hemispherical dome steel structures using steel structures, the steel structure needs to be composed of several micro-units. These micro-units are typically triangular, rectangular, or hexagonal structures. However, existing technologies lack mechanisms for adjusting the positions of these micro-units multiple times. The main method used is to cut steel structural profiles of different lengths and then weld multiple profiles directly together to try to maintain the hemispherical shape of the assembled steel structure. This construction method is difficult, requires a high level of expertise from the workers, and is not conducive to widespread use. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an adjustment device for a circular dome steel structure.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a circular dome steel structure adjustment device, comprising an adjustment mechanism, the adjustment mechanism comprising a lifting component and a connecting component disposed on the top of the lifting component, the connecting component comprising 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 bottom of the connecting plate is connected to the top of the lifting component, and an installation component for installing steel structure profiles is disposed on the connecting block, the installation component comprising an installation column disposed on the top of the connecting block, a lower plate fixedly sleeved on the side wall of the installation column near its bottom position, and an upper plate sleeved on the installation column and clearance-fitted, the bottom of the steel structure profile is connected to the top of the upper plate, a horizontal adjustment component for adjusting the distance between two adjacent installation columns is disposed between two adjacent installation columns, and a vertical adjustment component for adjusting the position of the installation columns is disposed on the connecting plate.

[0007] By adopting the above technical solution, workers can select steel structural profiles within a suitable length range according to the size requirements of the circular dome steel structure. The distance between two adjacent installation columns can be adjusted using horizontal adjustment components, and the position of the installation columns can be adjusted using vertical adjustment components. This, in turn, adjusts the distance between two adjacent upper plates, ensuring that the distance between two adjacent installation columns and two upper plates meets the installation requirements. This eliminates the cumbersome operation of strictly cutting steel structural profiles according to size requirements in traditional technology, reduces the difficulty of operation and the professional requirements of workers, and is conducive to its widespread application.

[0008] Furthermore, a screw with clearance fit is provided through the upper plate, and the lower end of the screw is threaded to the top of the lower plate. An upper annular groove and a lower annular groove are respectively provided at the corresponding positions of the bottom of the upper plate and the top of the lower plate. The horizontal adjustment component includes a T-shaped slider that slides with both the upper and lower annular grooves, 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-connected to the first connecting ball, a transverse screw fixed to the side of the first hemispherical shell away from the T-shaped slider, and a first threaded sleeve threaded to the end of the transverse screw away from the first hemispherical shell. The extension direction of the T-shaped slider is an arc shape that fits with both the upper and lower annular grooves. The first threaded sleeve is located between two adjacent mounting columns. Two T-shaped sliders, a first connecting rod, a first connecting ball, a first hemispherical shell, and a transverse screw are provided in the same group and are distributed in a mirror image about the first threaded sleeve.

[0009] By adopting the above technical solution, when it is necessary to adjust the distance between two mounting columns, the operator only needs to rotate the first threaded sleeve. Since the first threaded sleeve is threadedly connected to two mirrored transverse screws, the ends of the transverse screws are 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. This allows the two transverse screws to move closer or further apart, thereby controlling the two adjacent mounting columns to move closer or further apart. This allows the operator to adjust the position between the two mounting columns according to the size requirements of the circular dome steel structure, and then install steel structure profiles of suitable length.

[0010] Furthermore, 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 support strip 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 support strip fixed to the side of the second arc-shaped profile away from the first steel bar. The cross-sections of the first arc-shaped profile and the second arc-shaped profile are both arc-shaped. The side of the second arc-shaped profile away from the second steel bar is provided with an arc-shaped snap-fit ​​interface that engages with the first arc-shaped profile. The steel structure profile is provided with a snap-fit ​​assembly for connecting with a transverse screw.

[0011] Furthermore, the buckle assembly is provided with two sets and is respectively connected to the transverse screws on both sides of the first threaded sleeve. The buckle assembly includes a first block that is fixed to the bottom of the first steel bar and the bottom of the first support bar, a first buckle fixed to the bottom of the first block, a second block that is fixed to the bottom of the second steel bar and the bottom of the second support bar, and a second buckle fixed to the bottom of the second block. Both the first buckle and the second buckle are engaged with the transverse screws.

[0012] By adopting the above technical solution, since both the first and second clips in the two sets of clip components are engaged with the transverse screws, the stability of the steel structure profile is ensured during the adjustment of the two installation columns by the horizontal adjustment components. The circular dome steel structure is composed of micro-units made up of three steel structure profiles, forming a hemispherical structure. Multiple first or second support strips within each micro-unit provide good structural support for the glass within that micro-unit. After applying sealant between the glass and the first and second support strips, a good sealing and waterproofing effect is achieved.

[0013] Furthermore, a sliding rod is fixed to one end of the first arc-shaped profile, and an arc-shaped groove for sliding cooperation of the sliding rod is provided at one end of the second arc-shaped profile. The cross-section of the connecting plate is circular. The vertical adjustment assembly includes an annular body that cooperates with the connecting plate. Two clamping plates are fixed to the inner wall of the annular body. The sides of the two clamping plates that are close to each other are respectively attached to the top and bottom of the connecting plate. The vertical adjustment assembly also includes a lower screw hinged to the top of the clamping plate, a second threaded sleeve hinged to the upper end of the lower screw, an upper screw threaded to the upper end of the second threaded sleeve, a second hemispherical shell fixed to the upper end of the upper screw, 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 screwed, since the second threaded sleeve is threadedly connected to both the upper and lower screws, 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 and lower screws can be brought closer or further apart. With the cooperation of the universal joint, the tilt angle of the mounting column can be adjusted so that the staff can make fine adjustments to the position of the mounting column according to the installation requirements at any time.

[0015] Furthermore, a fastening bolt with a clearance fit is installed through the top of the mounting column. The lower end of the fastening bolt is fixed to the top of the connecting block. After the positions of 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. The mounting column is also welded to the first arc-shaped profile, the second arc-shaped profile, the upper plate, the first steel bar, and the second steel bar.

[0016] By adopting the above technical solution, after the workers have completed the installation of the steel structure profiles within the smallest triangular unit, the adjustment mechanism can be completely disassembled by unscrewing the fastening bolts for reuse. When the adjustment mechanism is needed to support the circular dome steel structure, simply tighten the fastening bolts.

[0017] Furthermore, the first threaded sleeve has a regular hexagonal cross-section, and the second threaded sleeve has cutting surfaces on both sides.

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

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

[0020] By adopting the above technical solution, during the installation of steel structure profiles, workers can make fine adjustments to the hydraulic jacks to adapt the adjustment mechanism to the installation needs of steel structure profiles at different heights.

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

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

[0023] By adopting the above technical solution, the probability of corrosion of the glass surface corresponding to the first steel bar, the first arc profile, the first support bar, the second steel bar, the second arc profile, the second support bar, and the mounting column is reduced, which helps to maintain 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 cutting steel structure profiles strictly according to size requirements in traditional technology, reduces the difficulty of operation and the professional requirements of staff, and is conducive to promotion and application; 2. In this application, when it is necessary to adjust the distance between two mounting columns, the worker only needs to rotate the first threaded sleeve. Since the first threaded sleeve is threadedly connected to two mirrored transverse screws, the ends of the transverse screws are 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. This allows the two transverse screws to move closer or further away from each other, thereby controlling the two adjacent mounting columns to move closer or further away from each other. This allows the worker to adjust the position between the two mounting columns according to the size requirements of the circular dome steel structure, and then install the steel structure profile of the appropriate length. 3. In this application, since both the first and second clips in the two sets of clip components are engaged with the transverse screw, the stability of the steel structure profile is ensured during the adjustment of the two installation columns by the horizontal adjustment component. The circular dome steel structure is composed of micro-units made up of three steel structure profiles, forming a hemispherical structure. Multiple first or second support strips within the micro-unit provide good structural support for the glass within that micro-unit. After applying sealant between the glass and the first and second support strips, a good sealing and waterproofing effect is achieved. Attached Figure Description

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-11As shown in the figure, this application discloses an adjustment device for a circular dome steel structure, including an adjustment mechanism 1. The adjustment mechanism 1 includes a lifting component 11 and a connecting component 12 disposed on the top of the lifting component 11. The connecting component 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 lifting component 11 is connected to the bottom of the connecting plate 121, and the connecting block 124 is provided with a mounting bracket for installation. The installation component 2 for the steel structure profile 5 includes an installation column 21 set on the top of the connecting block 124, a lower plate 22 fixedly sleeved on the side wall of the installation column 21 near its bottom, and an upper plate 23 sleeved on the installation column 21 with clearance fit. The bottom of the steel structure profile 5 is connected to the top of the upper plate 23. A horizontal adjustment component 3 for adjusting the distance between two adjacent installation columns 21 is provided, and a vertical adjustment component 4 for adjusting the position of the installation column 21 is provided on the connecting plate 121.

[0029] Based on the size requirements of the circular dome steel structure, the staff selects steel structural profiles 5 within a suitable length range. The horizontal adjustment component 3 can be used to adjust the distance between two adjacent installation columns 21, and the vertical adjustment component 4 can be used to adjust the position of the installation columns 21, thereby adjusting the distance between two adjacent upper plates 23. This ensures that the distance between the two adjacent installation columns 21 and the two upper plates 23 meets the installation requirements. This changes the cumbersome operation of strictly cutting the steel structural profiles 5 according to the size requirements in the traditional technology, reduces the difficulty of operation and the professional requirements of the staff, and is conducive to its widespread application.

[0030] A screw 231, which is clearance-fitted to the upper plate 23, is provided through the upper plate 23. The lower end of the screw 231 is threaded to the top of the lower plate 22. An upper annular groove 221 and a lower annular groove 232 are respectively provided at the bottom of the upper plate 23 and the top of the lower plate 22. The horizontal adjustment component 3 includes a T-shaped slider 31 that is slidably fitted with both the upper annular groove 221 and the lower annular groove 232, a first connecting rod 32 fixed to the side of the T-shaped slider 31 away from the axis of the mounting post 21, a first connecting ball 33 fixed to the end of the first connecting rod 32 away from the T-shaped slider 31, and a first connecting ball 33. The first hemispherical shell 34 is ball-connected, the transverse screw 35 is fixed to the side of the first hemispherical shell 34 away from the T-shaped slider 31, and the first threaded sleeve 36 is threadedly connected to the end of the transverse screw 35 away from the first hemispherical shell 34. The extension direction of the T-shaped slider 31 is an arc shape that matches both the upper annular groove 221 and the lower annular groove 232. The first threaded sleeve 36 is located between two adjacent mounting posts 21. 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 in the same group are all provided in two and are distributed in a mirror image with respect to the first threaded sleeve 36.

[0031] When it is necessary to adjust the distance between the two mounting columns 21, the operator only needs to rotate the first threaded sleeve 36. Since the first threaded sleeve 36 is threadedly connected to the two mirrored transverse screws 35, the ends of the transverse screws 35 are 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. This allows the two transverse screws 35 to move closer or further away from each other, thereby controlling the two adjacent mounting columns 21 to move closer or further away from each other. This allows the operator to adjust the position between the two mounting columns 21 according to the size requirements of the circular dome steel structure, and then install the steel structure profile 5 of a suitable length.

[0032] The steel structure profile 5 includes a first steel bar 51 disposed between two adjacent mounting columns 21, a first arc-shaped profile 52 fixed to one side of the first steel bar 51, a first support strip 53 fixed to the other side of the first steel bar 51, a second steel bar 54 located between two adjacent mounting columns 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 support strip 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. The side of the second arc-shaped profile 55 away from the second steel bar 54 is provided with an arc-shaped snap-fit ​​interface 551 that engages with the first arc-shaped profile 52. The steel structure profile 5 is provided with a snap-fit ​​assembly 6 for connecting with the transverse screw 35.

[0033] The snap-fit ​​assembly 6 has two sets and is connected to the transverse screws 35 on both sides of the first threaded sleeve 36 respectively. The snap-fit ​​assembly 6 includes a first block 61 that is fixed to the bottom of the first steel bar 51 and the bottom of the first support bar 53, a first snap 62 fixed to the bottom of the first block 61, a second block 63 that is fixed to the bottom of the second steel bar 54 and the bottom of the second support bar 56, and a second snap 64 fixed to the bottom of the second block 63. The first snap 62 and the second snap 64 are both snapped to the transverse screws 35.

[0034] Since both the first clip 62 and the second clip 64 in the two sets of clip components 6 are engaged with the transverse screw 35, the stability of the steel structure profile 5 is ensured during the adjustment of the two mounting columns 21 by the horizontal adjustment component 3. The circular dome steel structure is composed of multiple micro-units spliced ​​together to form a hemispherical structure, with multiple first support strips 53 or second support strips 56 within each micro-unit providing good structural support for the glass within that micro-unit. After the glass is coated with sealant between itself and the first support strips 53 and the second support strips 56, it achieves good sealing and waterproofing.

[0035] The first arc-shaped profile 52 has a slide rod 521 fixed at one end, and the second arc-shaped profile 55 has an arc-shaped groove 552 for sliding cooperation of the slide rod 521 at one end. The cross-section of the connecting plate 121 is circular. The vertical adjustment component 4 includes an annular body 41 that cooperates with the connecting plate 121. Two clamping plates 411 are fixed on the inner wall of the annular body 41. The sides of the two clamping plates 411 that are close to each other are respectively attached to the top and bottom of the connecting plate 121. The vertical adjustment component 4 also includes a lower screw 42 that is hinged to the top of the clamping plate 411, a second threaded sleeve 43 that is hinged to the upper end of the lower screw 42, an upper screw 44 that is threaded to the upper end of the second threaded sleeve 43, a second hemispherical shell 45 that is fixed to the upper end of the upper screw 44, a second connecting rod 46 that is fixed to one side of the connecting block 124, and a second connecting ball 47 that is fixed to the end of the second connecting rod 46 away from the connecting block 124 and cooperates 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 44 and the lower screw 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, the upper screw 44 and the lower screw 42 move closer or further apart. With the cooperation of the universal joint 123, the tilt angle of the mounting post 21 can be adjusted so that the staff can make fine adjustments to the position of the mounting post 21 according to the installation requirements at any time.

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

[0038] After the workers have completed the installation of the steel structure profile 5 within the smallest triangular unit, the adjusting mechanism 1 can be disassembled as a whole by unscrewing the fastening bolts 211 for reuse. When the adjusting mechanism 1 is needed to support the circular dome steel structure, simply tighten the fastening bolts 211.

[0039] To facilitate rotation of the first threaded sleeve 36, its cross-section is hexagonal. To facilitate rotation of the second threaded sleeve 43, both sides of the second threaded sleeve 43 are provided with cutting surfaces. The lifting assembly 11 includes a hydraulic jack 111 and a lifting rod 112 fixed to the upper end of the piston rod of the hydraulic jack 111. The upper end of the lifting rod 112 is fixed to the bottom of the connecting plate 121. During the installation of the steel structure profile 5, workers can make fine adjustments to the hydraulic jack 111 to adapt the adjustment mechanism 1 to the installation needs of the steel structure profile 5 at different heights.

[0040] In this embodiment, multiple first support strips 53 or second support strips 56 located inside the same triangular unit are all situated on the same plane. The first steel strip 51, first arc-shaped profile 52, first support strip 53, second steel strip 54, second arc-shaped profile 55, second support strip 56, and mounting column 21 are all made of stainless steel. This reduces the probability of corrosion of the glass surfaces corresponding to the first steel strip 51, first arc-shaped profile 52, first support strip 53, second steel strip 54, second arc-shaped profile 55, second support strip 56, and mounting column 21, thus helping to maintain the aesthetics of the circular dome steel structure building.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
