Description

Technical Field

[0001] The utility model relates to the field of assembled steel pipe columns, in particular to an assembled steel pipe column node connection device. Background Art

[0002] In traditional construction, node connections often require extensive on-site welding and bolting, which is not only time-consuming and labor-intensive but also subject to weather and other factors. Prefabricated steel pipe column node connections, on the other hand, can be prefabricated in a factory and assembled directly on site after transport, significantly reducing on-site work time.

[0003] At present, most of the prefabricated steel structure beam-column nodes are connections between square columns and I-beams, and circular steel pipe columns are less involved. The effect of direct welding between existing circular steel pipe columns and I-beams is relatively poor, and the node connection method is too simple. In traditional beam-column fully welded nodes, on-site welding is required, which greatly affects the construction speed and quality, and also affects the vibration resistance of the node, which is not conducive to consuming vibration energy. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an assembled steel pipe column node connection device, which can reduce welding, facilitate assembly, consume vibration energy, and avoid excessive shaking and node damage.

[0005] In order to solve the above problems, an assembled steel pipe column node connection device is adopted, which includes:

[0006] Round steel pipe column,

[0007] The L-shaped cross-section circular ring block is sleeved and fixed on the circular steel pipe column;

[0008] An inverted U-shaped cross-section semicircular ring block is slidably connected from top to bottom to the upper side of the L-shaped cross-section circular ring block, so that the upper side of the L-shaped cross-section circular ring block extends into the interior of the inverted U-shaped cross-section semicircular ring block;

[0009] A rectangular cross-section slider is radially slidably inserted into the annular inner wall of the inverted U-shaped cross-section semicircular ring block;

[0015] The mounting block is slidably inserted into the vertical side surface of the outer wall of the inverted U-shaped semicircular ring block;

[0016] The arc-shaped limiting plate is fixed on the insertion end of the installation block and is closely attached to the inner side surface of the outer wall of the semicircular ring block with an inverted U-shaped cross-section.

[0017] With such a structure, when the node vibrates, the rectangular cross-section slider moves left and right to form a damping block, which is beneficial to consume vibration energy and maintain node stability.

[0018] As a further improvement of the present invention, a sealing gasket is slidably sleeved on the bolt of the nut and bolt assembly and is tightened by a nut.

[0019] As a further improvement of the present invention, the outer wall of the inverted U-shaped cross-section semicircular ring block extends downward to the lower side of the outer wall of the L-shaped cross-section circular ring block; a horizontal rectangular slide groove is provided at the bottom of the vertical section of the L-shaped cross-section circular ring block; a horizontal section of the L-shaped plate is slidably installed in the rectangular slide groove, and the end of the horizontal section of the L-shaped plate abuts the outer wall of the inverted U-shaped cross-section semicircular ring block; one end of the auxiliary spring is fixed to the inner end of the horizontal section of the L-shaped plate, and the other end of the auxiliary spring is fixed to the second arc-shaped support plate, and the second arc-shaped support plate is fit with the circular steel pipe column.

[0020] As a further improvement of the present invention, a vertical strip limit groove is opened in the vertical section of the L-shaped plate, the lower end of the limit spring is fixed on the inner wall at the bottom of the strip limit groove, and the upper end of the limit spring is fixed to the lower end of the trapezoidal bar; the trapezoidal bar is slidably connected to the strip limit groove; a rectangular limit groove is opened at the bottom of the rectangular cross-section slider for the narrow head of the upper end of the trapezoidal bar to extend into, and the length of the rectangular limit groove is longer than the narrow head of the upper end of the trapezoidal bar, so that the narrow head of the upper end of the trapezoidal bar can slide in the rectangular limit groove.

[0021] As a further improvement of the present invention, a guide groove is provided on the horizontal wall of the inverted U-shaped semicircular ring block, a trapezoidal guide block is fixed on the upper end face of the vertical wall of the L-shaped circular ring block, and the L-shaped circular ring block is slidably inserted into the guide groove.

[0022] As a further improvement of the present invention, a trapezoidal sliding plate is fixed on the arc-shaped limiting plate to abut against the outer side surface of the vertical wall of the L-shaped cross-section circular ring block.

[0023] As a further improvement of the present invention, an annular groove is provided on the inner side surface of the outer wall of the inverted U-shaped cross-section semicircular ring block, the bottom surface of the annular groove is fixed with a vertical positioning strip block, and a corresponding positioning groove is provided on the end inclined surface of the trapezoidal sliding plate for the positioning strip block to be plugged in.

[0024] As a further improvement of the present invention, the lower end surface of the support block is an inclined surface.

[0025] As a further improvement of the present invention, the upper and lower sides of the end of the horizontal section of the L-shaped plate are inclined surfaces.

[0026] As a further improvement of the present invention, the outer end of the mounting block is spliced with an I-beam.

[0027] The utility model has the following beneficial effects:

[0028] (1) The utility model first welds the L-shaped cross-section circular ring block to the specified position on the circular steel pipe column, and then connects and fixes the two strip plates through a nut and bolt assembly. The two inverted U-shaped cross-section semicircular ring blocks connected together form a ring shape, and the two inverted U-shaped cross-section semicircular ring blocks are pushed downward. When the inverted U-shaped cross-section semicircular ring blocks are lowered, the two support blocks will contact the vertical ring wall of the L-shaped cross-section circular ring block. Under the action of the inclined surface, the support block will move closer to the circular steel pipe column, and the support block will drive the rectangular cross-section slide plate to move closer to the circular steel pipe column. The rectangular cross-section slide plate drives the first arc-shaped support plate, and the first arc-shaped support plate will contact the circular steel pipe column and support the circular steel pipe column. During the movement of the support block, the support spring will be continuously compressed. When the first arc-shaped support plate contacts and presses against the circular steel pipe column, the support spring will be compressed to the maximum state. When the support spring is compressed to the maximum state, it will produce the minimum contraction when the steel structure shakes as a whole, thereby avoiding excessive shaking and causing greater damage to the steel structure.

[0029] (2) During the continuous descent of the inverted U-shaped semicircular ring block, when the top inner wall of the inverted U-shaped semicircular ring block contacts the top of the inverted U-shaped semicircular ring block, the end of the L-shaped plate will contact the L-shaped circular ring block. Under the pressure of the inclined surface of the L-shaped plate, the L-shaped plate will approach the direction of the circular steel pipe column. The L-shaped plate will slide in the direction of the circular steel pipe column in the rectangular slide groove. The L-shaped plate will drive the auxiliary spring to move. The auxiliary spring will drive the second arc support plate to contact the circular steel pipe column. During the continuous movement of the L-shaped plate, the auxiliary spring will continue to compress and deform, so that the second arc support plate can effectively support the circular steel pipe column. At this time, the first arc support plate and the second arc support plate will support the circular steel pipe column at the same time, ensuring the stability of the inverted U-shaped semicircular ring block and the L-shaped circular ring block, and improving the stability of the steel structure at the same time.

[0030] (3) In the process of the L-shaped plate moving, the L-shaped plate will drive the trapezoidal bar in the bar-shaped limiting groove to approach the circular steel pipe column. In the process of the rectangular cross-section slide plate descending, the trapezoidal bar will contact the rectangular cross-section slide plate. When the trapezoidal bar slides, it will slide along the rectangular cross-section slide plate toward the circular steel pipe column. When the L-shaped plate stops moving and the auxiliary spring is compressed to the maximum extent, the trapezoidal bar will be stuck in the rectangular limiting groove at the bottom of the rectangular cross-section slide plate. The rectangular cross-section slide plate is fixed by the trapezoidal bar on the L-shaped plate, and the corresponding rectangular cross-section slide plate will also fix the L-shaped plate. When the left and right sway occurs, upward and downward forces will be generated. When the swaying generates an upward force, the second arc-shaped support plate will support and fix the circular steel pipe column, and the second arc-shaped support plate will transfer the force to the rectangular cross-section slide plate to share the force at the same time. When the swaying generates a downward force, the first arc-shaped support plate will play a corresponding supporting role and transfer the force to the L-shaped plate. At this time, the L-shaped plate will share the force with the first arc-shaped support plate, which can effectively improve the device's ability to withstand the force generated by the swaying, and further improve the stability of the steel structure.

[0031] (4) The utility model drives the installation block to descend during the process of the inverted U-section semicircular ring block descending, and the installation block drives the arc-shaped limiting plate and the trapezoidal sliding plate to descend at the same time, and the blocking strip block is stuck in the blocking groove of the trapezoidal sliding plate, and plays a certain limiting role on the trapezoidal sliding plate, so that the trapezoidal sliding plate can slide stably on the L-section circular ring block. When the inverted U-section semicircular ring block descends, the trapezoidal sliding plate will contact the L-section circular ring block. Under the action of the inclined surface of the trapezoidal sliding plate, the trapezoidal sliding plate will drive the arc-shaped limiting plate and the installation block to slide outward of the circular steel pipe column, and at the top of the inverted U-section semicircular ring block When the inner wall contacts the top of the L-section circular ring block, several mounting blocks will all extend out of the circular steel pipe column, and the trapezoidal guide block on the L-section circular ring block will also simultaneously penetrate the guide groove on the inverted U-section semicircular ring block. The penetration of the trapezoidal guide block into the guide groove can effectively improve the accuracy of the installation of the inverted U-section semicircular ring block on the L-section circular ring block. At the same time, the trapezoidal guide block can also be used to position the inverted U-section semicircular ring block to ensure that the installation angle of the inverted U-section semicircular ring block will not be wrong. Then, the corresponding I-beam can be installed to achieve rapid installation on the circular steel pipe column, effectively reducing welding work and improving installation efficiency.

[0043] Example 1

[0044] like Figure 1 - Figure 8 As shown, the utility model is an assembled steel pipe column node connection device, including a circular steel pipe column 1, on which a support mechanism 100 is provided. The support mechanism 100 includes an L-shaped cross-section circular ring block 101 fixedly sleeved on the outer wall of the circular steel pipe column 1, and two inverted U-shaped cross-section semicircular ring blocks 102 are slidably mounted on the L-shaped cross-section circular ring block 101. Rectangular cross-section slides 103 are respectively slidably mounted on the inner ring walls of the two inverted U-shaped cross-section semicircular ring blocks 102. The two rectangular cross-section slides 103 respectively penetrate the inner ring walls of the two inverted U-shaped cross-section semicircular ring blocks 102. The support mechanism 100 also includes:

[0045] The inner ends of the two rectangular cross-section slides 103 abut against the first arc-shaped support plate 104, and the two first arc-shaped support plates 104 are in contact with the circular steel pipe column 1. The outer ends of the two rectangular cross-section slides 103 are respectively fixedly installed with support blocks 105, and the support blocks 105 have grooves, which form a concave-convex combination with the outer ends of the rectangular cross-section slides 103. The side of the support block 105 opposite to the groove is made into a slope, and the outer sides of several support blocks 105 are in contact with the inner side surface of the vertical ring wall of the L-shaped cross-section circular ring block 101. Support springs 106 are fixedly installed between the upper parts of several support blocks 105 and the inner ring wall of the inverted U-shaped semicircular ring block 102, and several support springs 106 are fixedly connected to the outer side surfaces of the inner ring walls of the two inverted U-shaped semicircular ring blocks 102.

[0046] like Figure 1As shown, a fixing mechanism 2 is provided on the two inverted U-shaped cross-section semicircular ring blocks 102, and the fixing mechanism 2 includes two radially outward extending strip plates 201 respectively fixedly mounted on the ends of the outer ring walls of the two inverted U-shaped cross-section semicircular ring blocks 102, and nut and bolt assemblies 202 are respectively threadedly mounted on the two tight strip plates 201, and both nut and bolt assemblies 202 are slidingly sleeved with sealing gaskets 203 tightened by nuts.

[0047] First, weld the L-shaped circular ring block 101 to the designated position on the circular steel pipe column 1, then install the two inverted U-shaped semi-circular ring blocks 102 on the L-shaped circular ring block 101, and connect and fix the end strip plates 201 through the nut and bolt assembly 202 to form the two inverted U-shaped semi-circular ring blocks 102 into a ring shape.

[0048] like Figure 3 As shown, the inverted U-shaped cross-section semicircular ring block 102 and the upper L-shaped cross-section circular ring block 101 are provided with two adaptation mechanisms 3, the adaptation mechanism 3 includes an annular groove 301 opened on the inner side of the outer ring wall of the inverted U-shaped cross-section semicircular ring block 102, and a rectangular slide groove 302 is opened at the root of the vertical ring wall of the L-shaped cross-section circular ring block 101. An L-shaped plate 303 is slidably installed in the rectangular slide groove 302. The end of the L-shaped plate 303 is trapezoidal, and its upper side is also sloped. The end of the L-shaped plate 303 contacts the inner side of the outer ring wall of the inverted U-shaped cross-section semicircular ring block 102.

[0049] When the top inner side surface of the inverted U-section semicircular ring block 102 contacts the top of the L-section circular ring block 101, the end of the L-shaped plate 303 will contact the inner side surface of the outer ring wall of the inverted U-section semicircular ring block 102. Under the action of the upslope surface of the end of the L-shaped plate 303 contacting the outer ring wall of the inverted U-section semicircular ring block 102, the L-shaped plate 303 will approach the direction of the circular steel pipe column 1, and the L-shaped plate 303 will slide in the direction of the circular steel pipe column 1 in the rectangular slide groove 302.

[0050] like Figure 3 As shown, auxiliary mechanisms 4 are respectively provided on the two L-shaped plates 303. The auxiliary mechanism 4 includes an auxiliary spring 401 fixedly installed on the left side of the L-shaped plate 303. The left end of the auxiliary spring 401 is fixedly installed with a second arc-shaped support plate 402. The left side of the second arc-shaped support plate 402 is in contact with the circular steel pipe column 1.

[0051] The L-shaped plate 303 will drive the auxiliary spring 401 to move, and the auxiliary spring 401 will drive the second arc-shaped support plate 402 to contact the circular steel pipe column 1. During the continuous movement of the L-shaped plate 303, the auxiliary spring 401 will continue to compress and deform, so that the second arc-shaped support plate 402 can effectively support the circular steel pipe column 1. At this time, the second arc-shaped support plate 104 and the first arc-shaped support plate will simultaneously support the circular steel pipe column 1 to ensure the stability of the L-shaped section circular ring block 101 and the inverted U-shaped section semi-circular ring block 102, while improving the stability of the steel structure.

[0052] like Figure 3 and Figure 5 As shown, a limiting mechanism 5 is respectively provided on the two L-shaped plates 303, and the limiting mechanism 5 includes a strip-shaped limiting groove 501 opened in the vertical section of the L-shaped plate 303, and a limiting spring 502 is fixedly installed on the bottom inner wall of the strip-shaped limiting groove 501, and a trapezoidal bar 503 is fixedly installed on the top of the limiting spring 502, and the trapezoidal bar 503 is slidingly connected to the strip-shaped limiting groove 501, and a rectangular limiting groove 504 is opened at the bottom of the rectangular cross-section slide 103, and the top of the trapezoidal bar 503 extends into the rectangular limiting groove 504 and is slidingly connected to the rectangular limiting groove 504.

[0053] During the movement of the L-shaped plate 303, the L-shaped plate 303 will drive the trapezoidal bar 503 in the bar limiting groove 501 to approach the circular steel pipe column 1. During the descending process of the rectangular cross-section slide 103, the trapezoidal bar 503 will contact the rectangular slide 103. When the trapezoidal bar 503 slides, it will slide along the rectangular slide 103 toward the circular steel pipe column 1. When the L-shaped plate 303 stops moving and the auxiliary spring 401 is compressed to the maximum extent, the trapezoidal bar 503 will be stuck in the rectangular limiting groove 504 at the bottom of the rectangular slide 103, and the rectangular cross-section slide 103 will be locked by the trapezoidal bar 503 on the L-shaped plate 303.

[0054] like Figure 6 As shown, a guide mechanism 6 is respectively provided on the two inverted U-shaped cross-section semicircular ring blocks 102, and the guide mechanism 6 includes a guide groove 601 opened on the inverted U-shaped cross-section semicircular ring block 102, and a trapezoidal guide block 602 is fixedly installed on the top of the L-shaped cross-section circular ring block 101. The trapezoidal guide block 602 passes through the guide groove 601 and is slidably connected to the guide groove 601.

[0055] The trapezoidal guide block 602 passing through the guide groove 601 can effectively improve the accuracy of installing the inverted U-section semicircular ring block 102 on the L-section circular ring block 101. At the same time, the trapezoidal guide block 602 can also be used to position the inverted U-section semicircular ring block 102 to ensure that the installation angle of the inverted U-section semicircular ring block 102 will not be wrong.

[0056] like Figure 1 and Figure 8As shown, a number of movable mechanisms 7 are provided on the two inverted U-shaped semicircular ring blocks 102. The movable mechanism 7 includes a mounting block 701 slidably mounted on the outer ring wall of the inverted U-shaped semicircular ring block 102. The mounting block 701 passes through the outer ring wall of the inverted U-shaped semicircular ring block 102. An arc-shaped limiting plate 702 is fixedly mounted on the mounting block 701. The arc-shaped limiting plate 702 contacts the inner side surface of the outer ring wall of the inverted U-shaped semicircular ring block 102. A trapezoidal sliding plate 703 is fixedly mounted on the side of the arc-shaped limiting plate 702 opposite to the inner side surface of the outer ring wall of the inverted U-shaped semicircular ring block 102. An I-beam 704 is fixedly mounted on the outer end of the mounting block 701.

[0057] When the inverted U-shaped semicircular ring block 102 descends, the trapezoidal sliding plate 703 will contact the vertical ring wall of the L-shaped circular ring block 101. Under the action of the inclined surface of the trapezoidal sliding plate 703, the trapezoidal sliding plate 703 will drive the arc-shaped limiting plate 702 and the mounting block 701 to slide outward from the circular steel pipe column 1. When the top inner wall of the inverted U-shaped semicircular ring block 102 contacts the top of the L-shaped circular ring block 101, several mounting blocks 701 will all extend out of the circular steel pipe column 1.

[0058] like Figure 8 As shown, a plurality of trapezoidal sliding plates 703 are respectively provided with a locking mechanism 8, and the locking mechanism 8 includes a locking groove 801 opened at the bottom of the trapezoidal sliding plate 703, and a locking bar block 802 is fixedly installed on the top inner wall of the annular groove 301, and the top end of the locking bar block 802 extends into the locking groove 801 and is slidably connected to the locking groove 801.

[0059] The positioning bar block 802 is in the positioning slot 801 of the trapezoidal sliding plate 703, which can limit the trapezoidal sliding plate 703 to a certain extent, so that the trapezoidal sliding plate 703 can slide stably on the L-section circular ring block 101 for precise docking.

[0060] When using this embodiment, first weld the L-shaped cross-section circular ring block 101 to the designated position on the circular steel pipe column 1, and then fix the corresponding strip plates 201 of the two inverted U-shaped cross-section semicircular ring blocks 102 through the nut and bolt assembly 202 to form a ring shape, and push the two inverted U-shaped cross-section semicircular ring blocks 102 downward. When the inverted U-shaped cross-section semicircular ring blocks 102 descend, they will drive the two support blocks 105 to descend, and the two support blocks 105 will contact the inner side of the vertical ring wall of the L-shaped cross-section circular ring block 101. The slope of the support block 105 will be under the action of the pressure on the slope. Make the support block 105 approach the direction of the circular steel pipe column 1, the support block 105 drives the rectangular cross-section slide 103 to approach the circular steel pipe column 1, the rectangular cross-section slide 103 drives the first arc-shaped support plate 104 to approach the circular steel pipe column 1, the first arc-shaped support plate 104 will contact the circular steel pipe column 1 and support the circular steel pipe column 1. During the movement of the support block 105, the support spring 106 will be continuously compressed. When the first arc-shaped support plate 104 contacts and presses against the circular steel pipe column 1, the support spring 106 will be compressed to the maximum state. The support spring 106 The compression to the maximum state will produce the smallest contraction when the steel structure shakes as a whole; in the process of continuous descent of the inverted U-section semicircular ring block 102, when the top inner wall of the inverted U-section semicircular ring block 102 contacts the top of the L-section circular ring block 101, the end of the horizontal section of the L-shaped plate 303 will contact the inner side surface of the outer ring wall of the inverted U-section semicircular ring block 102, and under the action of the pressure on the end inclined surface of the horizontal section of the L-shaped plate 303, the L-shaped plate 303 will move closer to the circular steel pipe column 1, and the L-shaped plate 303 will move towards the circular steel pipe column 1 in the rectangular slide 302. When the steel pipe column 1 slides in the direction of the L-shaped plate 303, the auxiliary spring 401 will move, and the auxiliary spring 401 will drive the second arc-shaped support plate 402 to contact the circular steel pipe column 1. During the continuous movement of the L-shaped plate 303, the auxiliary spring 401 will continue to compress and deform, so that the second arc-shaped support plate 402 can effectively support the circular steel pipe column 1. At this time, the first arc-shaped support plate 104 and the second arc-shaped support plate 402 will simultaneously support the circular steel pipe column 1 to ensure the stability of the L-shaped cross-section circular ring block 101 and the inverted U-shaped cross-section semi-circular ring block 102;

[0061] As the L-shaped plate 303 moves, the L-shaped plate 303 drives the trapezoidal bar 503 in the bar-shaped limiting groove 501 toward the circular steel pipe column 1. As the rectangular cross-section slide 103 descends, the trapezoidal bar 503 contacts the rectangular cross-section slide 103. As the trapezoidal bar 503 slides, it slides along the rectangular cross-section slide 103 toward the circular steel pipe column 1. When the L-shaped plate 303 stops moving and the auxiliary spring 401 is compressed to the maximum extent, the trapezoidal bar 503 is stuck in the rectangular limiting groove 504 at the bottom of the rectangular cross-section slide 103. The rectangular cross-section slide 103 is fixed by the trapezoidal bar 503 on the L-shaped plate 303, and the corresponding rectangular cross-section slide 1 03 will also fix the L-shaped plate 303. When the steel structure shakes left and right, it will generate upward and downward forces. When the shaking generates an upward force, the second arc-shaped support plate 402 will support and fix the circular steel pipe column 1, and the second arc-shaped support plate 402 will transfer the force to the rectangular cross-section slide 103, and the rectangular cross-section slide 103 will share the force at the same time. When the shaking generates a downward force, the first arc-shaped support plate 104 will play a corresponding supporting role and transfer the force to the L-shaped plate 303. At this time, the L-shaped plate 303 will share the force with the first arc-shaped support plate 104. When the inverted U-shaped cross-section semicircular ring block 102 descends, The process will drive the installation block 701 to descend, and the installation block 701 will drive the arc limit plate 702 and the trapezoidal sliding plate 703 to descend at the same time. Since the blocking bar block 802 is in the blocking slot 801 of the trapezoidal sliding plate 703, it will play a certain limiting role on the trapezoidal sliding plate 703, so that the trapezoidal sliding plate 703 can slide stably. When the inverted U-section semicircular ring block 102 descends, the trapezoidal sliding plate 703 will contact the L-section circular ring block 101. Under the action of the inclined surface of the trapezoidal sliding plate 703, the trapezoidal sliding plate 703 will drive the arc limit plate 702 and the installation block 701 to slide toward the outside of the circular steel pipe column 1. When contacting the top of the semicircular ring block 101, several installation blocks 701 will all extend out of the circular steel pipe column 1, and the trapezoidal guide block 602 on the L-section circular ring block 101 will also simultaneously penetrate the guide groove 601 on the inverted U-section semicircular ring block 102. The penetration of the trapezoidal guide block 602 into the guide groove 601 can effectively improve the accuracy of the inverted U-section semicircular ring block 102 being installed on the L-section circular ring block 101. At the same time, the trapezoidal guide block 602 can also be used to position the inverted U-section semicircular ring block 102 to ensure that the installation angle of the inverted U-section semicircular ring block 102 will not be wrong, and then the corresponding I-beam 704 can be installed to achieve quick installation on the circular steel pipe column 1.
