Description

Technical Field

[0001] This utility model relates to the field of steel structure buildings, and in particular to a connection node between a connecting corridor steel beam and the main structure. Background Technology

[0002] With the rapid development of my country's economy and changes in social needs, high-rise building structures are evolving towards higher levels, higher strength, and composite structures. Simultaneously, their architectural design is shifting from single-function applications to comprehensive, multi-purpose uses. The demands for multi-functional use and architectural aesthetics inevitably lead to complex and varied structural forms, particularly in the floor plans and facades of high-rise buildings. In recent years, structural forms with large foundations and multiple steel structures interconnected by connecting corridors and steel beams have become increasingly common.

[0003] In existing technologies, the steel beams of connecting corridors are all lapped on the support platform of the main steel structure. When the span of the steel beams of the connecting corridor is large and / or the installation height is high, high requirements are placed on the load-bearing capacity of the support platform and the reliability of the connection between the steel beams of the connecting corridor and the support platform. Especially when the steel beams of the connecting corridor are installed at a high position, under the action of strong winds, the steel beams of the connecting corridor may sway and may collide with the main steel structure, which will affect the stability of the connection of the steel beams of the connecting corridor and pose a safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a connection node between the steel beam of the connecting corridor and the main structure, so as to solve the problems existing in the prior art.

[0005] The purpose of this utility model is achieved as follows: A connection node between a connecting corridor steel beam and the main structure includes two main steel structures, with a connecting corridor steel beam between the main steel structures and an expansion joint between the main steel structures and the connecting corridor steel beam. A bearing platform is connected to the inner side of the main steel structure, and the bearing platform is connected to the steel column or steel frame beam of the main steel structure. The bearing platform includes an upper support plate and a lower support plate arranged in parallel. At least three vertical connecting plates are vertically connected between the upper support plate and the lower support plate. Several vertical stiffening plates are vertically connected between adjacent vertical connecting plates. A connecting support is provided on the bearing platform. The bottom of the four corners of the connecting corridor steel beam is connected to the connecting support. The connecting support includes a fixed hinge support, a transverse sliding support, and two bidirectional sliding supports. The fixed hinge support and the transverse sliding support are arranged opposite to each other, and the pair of bidirectional sliding supports are arranged opposite to each other.

[0006] The connection node between the connecting corridor steel beam and the main structure of this utility model has a bearing platform that can provide stable support for the connecting corridor steel beam. Furthermore, through the setting of expansion joints and connecting supports, the horizontal displacement of the connecting corridor steel beam structure caused by factors such as temperature changes and strong winds can be adapted to by the rotation and sliding of the connecting corridor steel beam, thereby improving the connection stability of the connecting corridor steel beam and ensuring the safety of steel structure buildings.

[0007] As a further improvement of this utility model, a sub-connecting corridor is fixedly connected to one side of the connecting corridor steel beam, and the two corners of the other end of the sub-connecting corridor are connected to the adjacent steel structure main body through bidirectional sliding supports, which expands the scale of the steel structure building while ensuring convenient connectivity and connection stability.

[0008] As a further improvement of this utility model, the bidirectional sliding support comprises, from top to bottom, an upper connecting seat, a slider, a rotating block, a rotating seat, and a lower connecting seat. The upper surface of the upper connecting seat is fixedly connected to the steel beam of the connecting corridor. The slider is horizontally slidably connected to the upper connecting seat and to the rotating block. The lower end of the rotating block is spherical and is inserted into the rotating seat for rotational connection. The rotating seat is horizontally slidably connected to the lower connecting seat, and the bottom of the lower connecting seat is fixedly connected to the bearing platform. Thus, by the relative left-right horizontal sliding of the slider and the upper connecting seat, and the relative front-back horizontal sliding of the rotating seat and the lower connecting seat, the displacement requirements of the connecting support can be met, achieving bidirectional sliding. Furthermore, the rotating block can rotate relative to the rotating seat, further improving the stability of the connection.

[0009] As a further improvement of this utility model, the upper end of the slider is provided with an upper flat slide plate, the lower surface of the upper connecting seat is provided with an upper stainless steel plate, the width of the upper stainless steel plate is adapted to the upper flat slide plate and the length is greater than the length of the upper flat slide plate, the lower end of the slider is provided with a middle flat slide plate, the upper surface of the rotating block is provided with a middle stainless steel plate, both the middle flat slide plate and the middle stainless steel plate are circular, the lower end of the rotating block is provided with a spherical slide plate, the inner bottom surface of the rotating seat is provided with a spherical stainless steel plate, the upper surface of the lower connecting seat is provided with a lower flat slide plate, the lower surface of the rotating seat is provided with a lower stainless steel plate, the lower flat slide plate is adapted to the width and the length is greater than the length of the lower stainless steel plate, and the length directions of the upper stainless steel plate and the lower flat slide plate are perpendicular, thereby improving the smoothness of forward and backward, left and right horizontal sliding and rotation.

[0010] As a further improvement of this utility model, the upper support plate and the lower support plate are 50mm thick, the vertical connecting plate is 25mm thick, and the vertical stiffening plate is 20mm thick, so as to provide stable support for the steel beam of the connecting corridor.

[0011] As a further improvement of this utility model, the expansion joint width is 200mm, which effectively avoids the risk of collision between the steel beam of the connecting corridor and the main steel structure that may occur under the influence of temperature changes or strong winds.

Detailed Implementation

[0019] like Figure 1-4 The connection node between the connecting corridor steel beam and the main structure shown includes two main steel structures 1, with a connecting corridor steel beam 2 between the main steel structures 1, and an expansion joint 3 between the main steel structure 1 and the connecting corridor steel beam 2. The expansion joint 3 is 200mm wide, which effectively avoids the risk of collision between the connecting corridor steel beam 2 and the main steel structure 1 that may occur under the influence of temperature changes or strong winds.

[0020] A support platform is connected to the inner side of the main steel structure 1. The support platform is welded and fixed to the steel columns 4 of the main steel structure 1. The support platform includes an upper support plate 5 and a lower support plate 6 arranged in parallel. Three vertical connecting plates 7 are vertically welded between the upper support plate 5 and the lower support plate 6. Several vertical stiffening plates 8 are vertically welded between adjacent vertical connecting plates 7. The upper and lower ends of the vertical stiffening plates 8 are welded and fixed to the upper support plate 5 and the lower support plate 6, respectively. The thickness of the upper support plate 5 and the lower support plate 6 is 50mm, the thickness of the vertical connecting plates 7 is 25mm, and the thickness of the vertical stiffening plates 8 is 20mm, so that the support platform can provide stable support for the connecting corridor steel beam 2.

[0021] Connecting supports are provided on the support platform. The bottom of the four corners of the connecting corridor steel beam 2 are connected to the connecting supports. The connecting supports include a fixed hinge support 9, a transverse sliding support 10, and two bidirectional sliding supports 11. The fixed hinge support 9 and the transverse sliding support 10 are arranged opposite to each other, and the pair of bidirectional sliding supports 11 are arranged opposite to each other, thereby improving the connection stability of the connecting corridor steel beam 2 and ensuring the safety of the steel structure building.

[0022] Specifically, in this embodiment, the bidirectional sliding support 11 includes, from top to bottom, an upper connecting seat 12, a slider 13, a rotating block 14, a rotating seat 15, and a lower connecting seat 16. The upper surface of the upper connecting seat 12 is fixedly connected to the connecting corridor steel beam 2. The slider 13 is horizontally slidably connected to the upper connecting seat 12 and to the rotating block 14. The lower end of the rotating block 14 is spherical, and its lower end is inserted into the rotating seat 15 and rotatably connected. The rotating seat 15 is horizontally slidably connected to the lower connecting seat 16, and the bottom of the lower connecting seat 16 is fixedly connected to the support platform. Thus, by the relative left-right horizontal sliding of the slider 13 and the upper connecting seat 12, and the relative front-back horizontal sliding of the rotating seat 15 and the lower connecting seat 16, the displacement requirements of the connecting support can be met, achieving bidirectional sliding. Furthermore, the rotating block 14 can rotate relative to the rotating seat 15, further improving the stability of the connection.

[0023] Furthermore, the upper end of the slider 13 is provided with an upper flat sliding plate 17, and the lower surface of the upper connecting seat 12 is provided with an upper stainless steel plate. The width of the upper stainless steel plate is adapted to the upper flat sliding plate 17, and its length is greater than the length of the upper flat sliding plate 17, so that the upper flat sliding plate 17 can slide along the length direction of the upper stainless steel plate. The lower end of the slider 13 is provided with a middle flat sliding plate 18, and the upper surface of the rotating block 14 is provided with a middle stainless steel plate. Both the middle flat sliding plate 18 and the middle stainless steel plate are circular. The lower end of the rotating block 14 is provided with a spherical sliding plate 19, and the inner bottom surface of the rotating seat 15 is provided with a spherical stainless steel plate, so that the rotating block 14 can rotate flexibly within the rotating seat 15. The upper surface of the lower connecting seat 16 is provided with a lower flat sliding plate 20, and the lower surface of the rotating seat 15 is provided with a lower stainless steel plate. The width of the lower flat sliding plate 20 is adapted to the width of the lower flat sliding plate 20, and its length is greater than the length of the lower stainless steel plate, so that the rotating seat 15 can slide along the length direction of the lower flat sliding plate 20. The upper stainless steel plate and the lower flat sliding plate 20 are perpendicular in length direction, thus realizing the bidirectional sliding function of the support. The upper sliding plate 17, middle sliding plate 18, spherical sliding plate 19, and lower sliding plate 20 are preferably made of polytetrafluoroethylene (PTFE). Based on the aforementioned bidirectional sliding support 11, those skilled in the art can obtain the transverse sliding support 10 by simply changing the sliding connection between the swivel seat 15 and the lower connecting seat 16 to a fixed connection. Furthermore, based on the transverse sliding support 10, changing the sliding connection between the upper connecting seat 12 and the slider 13 to a fixed connection yields the fixed hinge support 9. Of course, the fixed hinge support 9, transverse sliding support 10, and bidirectional sliding support 11 used in the connection node between the connecting corridor steel beam and the main structure of this utility model are not limited to the above structures; any existing fixed hinge support 9, transverse sliding support 10, and bidirectional sliding support 11 structures can also be used.

Figure 1The main difference in the illustrated embodiment is that a sub-connecting corridor 20 is fixedly connected to one side of the connecting corridor steel beam 2, and the two corners of the other end of the sub-connecting corridor 20 are connected to the adjacent steel structure main body 1 via bidirectional sliding supports 11. This ensures convenient connectivity and connection stability while expanding the scale of the steel structure building. Furthermore, in this embodiment, the two corners of the other end of the sub-connecting corridor 20 are respectively connected to the steel column 4 and the steel frame beam 21 of the steel structure main body 1. The specific connection structure is as follows... Figure 6 As shown, a bearing platform is welded and fixed to the inner side of the steel frame beam 21, and the bidirectional sliding support 11 is fixed on the bearing platform.

[0025] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
