Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a steel structure spherical support. Background Technology

[0002] A steel structure spherical bearing is a device used to support and fix steel structures. It consists of a spherical surface and a bearing base. It can withstand horizontal and vertical loads while allowing the structure to move and deform in different directions. It is commonly used for the support and fixation of large structures such as bridges, buildings, and towers. With the development of steel structure construction, steel structures are being used more and more, and correspondingly, the use of steel structure spherical bearing nodes is also increasing.

[0003] Existing steel structure spherical supports (such as Chinese patent with announcement number CN213868322U) cannot be properly adjusted at multiple angles according to requirements when using large-span steel beam spherical support nodes, resulting in reduced adaptability of the structure during use. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a steel structure spherical support is provided to solve the problem that existing steel structure spherical supports cannot be properly adjusted to multiple angles according to requirements and have low adaptability.

[0005] To achieve the above objectives, a steel structure spherical support is provided, comprising:

[0006] A support column has a base plate detachably mounted on one end and a plurality of limiting members mounted on the other end. The plurality of limiting members are continuously arranged along the circumferential direction of the support column, and the plurality of limiting members and the other end of the support column enclose a first receiving groove. The limiting members have a through groove communicating with the first receiving groove. A pressing member is movably arranged in the through groove. An elastic pressure plate is formed at the end of the through groove away from the first receiving groove, and the elastic pressure plate abuts against the pressing member.

[0007] A supporting arc plate is movably accommodated in the first accommodating groove. The inner arc surface of the supporting arc plate faces the opening of the first accommodating groove. Multiple sets of clamping pieces are formed on the outer edge of the supporting arc plate. Each set of clamping pieces includes two opposing arc-shaped flanges. The two arc-shaped flanges are respectively arranged on opposite sides of the through groove. The multiple sets of clamping pieces and the supporting arc plate enclose and form a spherical second accommodating groove.

[0008] A ball head is rotatably embedded in the second receiving groove, and the ball head is connected to a mounting plate for installing a steel structure via a support rod;

[0009] The pressurizing structure includes a support formed outside the limiting member. The support is rotatably mounted with a rotating shaft that abuts against the elastic pressure plate. A protrusion is mounted on one side of the rotating shaft, and a toggle part is mounted on the other side of the rotating shaft. By rotating the toggle part, the toggle part abuts against the outside of the limiting member, causing the protrusion to press against the elastic pressure plate. The elastic pressure plate pushes against the pressing member, causing the pressing member to press against a set of clamping pieces. The two arc-shaped flanges of the set of clamping pieces undergo plastic deformation to press against the ball head, thereby locking the ball head with the multiple sets of clamping pieces.

[0010] Furthermore, a limiting flange is formed at the lower end of the support column, a column foot sleeve is movably fitted at the lower end of the support column, an assembly flange is formed at the lower end of the column foot sleeve, the assembly flange is detachably installed on the base plate, a snap-fit ​​flange is formed at the upper end of the column foot sleeve, and a locking sleeve is adjustablely fitted at the middle position of the support column, the locking sleeve and the limiting flange are clamped in the snap-fit ​​flange.

[0011] Furthermore, the locking sleeve has an internal thread, the support column has an external thread, and the locking sleeve is screwed into the support column.

[0012] Furthermore, the side of the pressing member is provided with a plurality of positioning grooves, the plurality of positioning grooves being arranged around the center of the ball head, and the elastic pressure plate being formed with positioning blocks for being inserted into the positioning grooves to avoid loss of rotation of the pressing member.

[0013] Furthermore, the number of the limiting components is four.

[0014] Furthermore, the protrusion is arranged along the axial direction of the rotating shaft.

[0015] Furthermore, the rib has a root near the pivot and a head away from the pivot, and the width of the rib gradually decreases from the root to the head.

[0016] The beneficial effects of this invention are as follows: the steel structure spherical support of this invention, through the corresponding cooperation of various structures, allows the mounting plate and support rod to be adjusted in different directions with the ball head and supporting arc plate as the center point. At the same time, the pressing member is displaced in the through groove due to the traction force of the convex rib displacement, and pressurizes the supporting arc plate, so that the supporting arc plate and ball head can be clamped again after adjustment, thereby fixing the angle of the support rod adjustment. Through the spherical cross-section of the supporting arc plate and ball head, the limiting member wraps the outside of the supporting arc plate and the outside of the ball head. When adjusting the ball head, the function of progressive wrapping and limiting is realized, ensuring the stability of angle adjustment when the device supports the steel structure.

[0025] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Reference Figures 1 to 7 As shown, the present invention provides a steel structure spherical support, comprising: a support column 1, a supporting arc plate 2, a ball head 3, and a pressure structure.

[0028] In this embodiment, the support column 1 is cylindrical in shape. Specifically, the support column is a cylindrical tube. A base plate 11 is detachably mounted on one end of the support column 1.

[0029] As a preferred implementation method, see [reference]. Figure 2 and Figure 3As shown, a limiting flange 15 is formed at the lower end of the support column 1. The limiting flange is arranged in a circle along the circumference of the support column. A column base sleeve 16 is movably fitted onto the lower end of the support column 1. An assembly flange 161 is formed at the lower end of the column base sleeve 16. The assembly flange is arranged in a circle along the circumference of the column base sleeve. The assembly flange 161 is detachably mounted to the base plate 11. A snap-fit ​​flange 162 is formed at the upper end of the column base sleeve 16. The snap-fit ​​flange is arranged in a circle along the circumference of the column base sleeve. The width of the limiting flange is adapted to the width of the snap-fit ​​flange. A locking sleeve 17 is adjustablely fitted at the middle position of the support column 1. The locking sleeve 17 and the limiting flange 15 are clamped within the snap-fit ​​flange 162.

[0030] Continue reading Figure 3 As shown, in this embodiment, the locking sleeve 17 has an internal thread. The support post 1 has an external thread. The locking sleeve 17 is screwed into the support post 1.

[0031] In this embodiment, a rib is formed on the upper surface of the limiting flange, and the rib is arranged in a circle along the circumference of the support column. An annular groove is formed at the bottom of the fastening flange. After the locking sleeve 17 and the limiting flange 15 are clamped in the fastening flange 162, the rib is embedded in the annular groove of the fastening flange. The lower end face of the locking sleeve presses against the upper surface of the fastening flange.

[0032] Multiple limiting members 12 are installed at the other end of the support column 1. The multiple limiting members 12 are continuously arranged along the circumference of the support column 1. The multiple limiting members 12 and the other end of the support column 1 enclose a first receiving groove. Each limiting member 12 has a through groove communicating with the first receiving groove. A pressing member 13 is movably disposed in the through groove. An elastic pressure plate 14 is formed at the end of the through groove away from the first receiving groove. The elastic pressure plate 14 abuts against the pressing member 13.

[0033] In this embodiment, there are four limiting members 12. The limiting members are C-shaped. The pressing members are also C-shaped. The outer diameter of the pressing members is adapted to the inner diameter of the through groove of the limiting members. The pressing members can slide along the axial direction of the through groove and can rotate along the circumferential direction of the limiting members. Both the pressing members and the limiting members are circular. The pressing members and the limiting members are coaxially or concentrically arranged.

[0034] See Figure 5 , Figure 6 and Figure 7 As shown, the supporting arc plate 2 is movably accommodated within the first receiving groove. The inner arc surface of the supporting arc plate 2 faces the opening of the first receiving groove. Multiple sets of clamping pieces are formed on the outer edge of the supporting arc plate 2. Each set of clamping pieces includes two opposing arc-shaped flanges 21. The two arc-shaped flanges 21 are respectively located on opposite sides of the through groove. The multiple sets of clamping pieces and the supporting arc plate 2 enclose a spherical second receiving groove.

[0035] The ball head 3 is rotatably fitted into the second receiving groove. The ball head 3 is connected to a mounting plate 32 for installing a steel structure via a support rod 31. The pressing member has a through groove, the inner diameter of which is adapted to the outer diameter of the support rod. When the ball head is rotated, the support rod is fitted into the through groove of the pressing member. Figure 7 As shown, the support rod is embedded between a set of arc-shaped flanges on one side of the supporting arc plate and in the through groove of the pressing member. Of course, Figure 7 The image shows one of the extreme positions of the support rod.

[0036] The pressurizing structure includes a support 41 and a rotating shaft 42. The support 41 is formed outside the limiting member 12. The rotating shaft 42, which abuts against the elastic pressure plate 14, is rotatably mounted on the support 41. A protrusion 421 is mounted on one side of the rotating shaft 42. An actuating part 422 is mounted on the other side of the rotating shaft 42.

[0037] During construction, the steel structure to be installed is hoisted to the installation position, and then the ball head is rotated to adjust the angle of the mounting plate. The steel structure to be installed (such as H-beams) is then bolted onto the mounting plate. By rotating the actuating part 422, the actuating part 422 is pressed against the outside of the limiting member 12, causing the protrusion 421 to press against the elastic pressure plate 14. The elastic pressure plate 14 pushes against the pressing member 13, causing the pressing member 13 to press against a set of clamping pieces. The two arc-shaped flanges 21 of the set of clamping pieces undergo plastic deformation to press against the ball head 3, thereby locking the ball head 3 with multiple sets of clamping pieces.

[0038] In this embodiment, a support is provided on the outer side of the limiting member. Two ear plates are on the support. The rotating shaft is circular. Both ends of the rotating shaft are rotatably mounted on the two ear plates. A protruding rib 421 is provided along the axial direction of the rotating shaft 42.

[0039] In a preferred embodiment, the rib 421 has a root near the pivot 42 and a head away from the pivot 42. The width of the rib 421 gradually decreases from the root to the head.

[0040] In some embodiments, the cross-section of the ridge is semi-circular.

[0041] In this embodiment, when the elastic pressure plate naturally contacts the pressing member (i.e., when the elastic pressure plate is attached to the pressing member), the circumference of the rotating shaft is attached to the elastic pressure plate; when the elastic pressure plate needs to apply pressure to the pressing member to lock the ball head, the downward rotating part causes the convex rib to move and press the elastic pressure plate towards the center of the ball head. The positioning block of the elastic pressure plate is inserted into the positioning groove of the pressing member. The pressing members on multiple sides of the supporting arc plate simultaneously press the arc-shaped flange on the supporting arc plate to press the ball head, thereby locking the ball head, so that the support rod is set at a preset angle.

[0042] In this embodiment, a column base sleeve is disposed on one side of the substrate. A support column is provided on the column base sleeve, and multiple limiting members are distributed circumferentially around the end of the support column and along its axis. The limiting members are arc-shaped and integrally formed with the support column. A supporting arc plate with a spherical cross-section is movably connected between the multiple limiting members.

[0043] A ball head is provided inside the supporting arc plate. A support rod extending to the outside of the supporting arc plate is provided at one end of the ball head. A mounting plate for supporting the steel structure to be installed is provided at one end of the support rod. A limiting groove for positioning is provided on the mounting plate.

[0044] Multiple limiting components are provided with through slots. A notch is formed between the two arc-shaped flanges of each set of clamps on the supporting arc plate. Multiple notches are distributed circumferentially along the axis of the supporting arc plate. Pressing components are respectively provided within the multiple through slots and outside the notches. All pressing components are slidably connected to the supporting arc plate, and the pressing components match the notches.

[0045] The upper part of the pressing component has a through groove for guiding the support rod.

[0046] The support column has a limiting flange located inside the column base sleeve at its bottom. A snap-fit ​​flange is located at the top of the column base sleeve, on the outer side of the support column. Several annular grooves are distributed around the bottom inner wall of the snap-fit ​​flange, circumferentially along its axis. Several protrusions, each engaging with a corresponding annular groove, are distributed around the top of the limiting flange, circumferentially along its axis. A locking sleeve is located on the outer side of the support column, and threads are fixedly provided on the surface of the support column for threaded connection with the locking sleeve.

[0047] In use, the operator installs the device in the designated location and bolts the mounting plate to the steel structure to be supported, such as an H-beam. By rotating the locking sleeve, the support column is displaced due to the traction force of the rotating locking sleeve, allowing each protrusion to engage in the corresponding annular groove, limiting the limiting flange, thereby positioning the support column and facilitating the operator's installation of the device.

[0048] Furthermore, when the initial device supports the H-beam, the ball head can be rotated within the supporting arc plate by bending the mounting plate and the support rod as needed. At the same time, through the notch and the pressing component, the support rod and the mounting plate can be oriented in different directions with the ball head and the supporting arc plate as the center point. The support rod is then limited by the notch and the pressing component, thereby locking the angle of the support rod after adjustment.

[0049] Simultaneously, by turning the actuating part, the protrusion is driven to rotate along the axis point at the connection between the actuating part and the support, so that the protrusion can squeeze the elastic pressure plate. When the elastic pressure plate deforms due to the traction force of the protrusion displacement, each positioning block will be stuck into the positioning groove, while the pressing part will be displaced in the through groove due to the traction force of the protrusion displacement, and pressurize the supporting arc plate, so that the supporting arc plate and the ball head can be clamped again after adjustment, thereby fixing the angle of the support rod adjustment.

[0050] By using the spherical cross-section of the supporting arc plate and the ball head, the limiting component wraps around the outside of the supporting arc plate and the outside of the ball head. When adjusting the ball head, it achieves the function of progressively wrapping and limiting, ensuring the stability of angle adjustment when the device supports the steel structure.

[0051] The steel structure spherical support of the present invention, through the corresponding cooperation of various structures, allows the mounting plate and support rod to be adjusted in different directions with the ball head and supporting arc plate as the center points. At the same time, the pressing member is displaced in the through groove due to the traction force of the convex rib displacement, and pressurizes the supporting arc plate, so that the supporting arc plate and ball head can be clamped again after adjustment, thereby fixing the angle of the support rod adjustment. Through the spherical cross-section of the supporting arc plate and ball head, the limiting member wraps around the outside of the supporting arc plate and the outside of the ball head. When adjusting the ball head, the function of progressive wrapping and limiting is realized, ensuring the stability of angle adjustment when the device supports the steel structure.

[0052] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
