[0002] The multi-limb lattice steel pipe column is a composite structure composed of multiple steel pipe limbs connected by tie materials (such as tie plates or tie bars). It is widely used in construction and bridge engineering. When used, for its aesthetics, it is generally necessary to attach a curved curtain wall to the outside of the multi-limb lattice steel pipe column.

[0003] By arranging the materials at a position far away from the inertia axis, the multi-limb lattice steel pipe column can significantly enhance the bending performance of the component under the same axial resistance conditions while saving materials. In addition, the structural form can achieve a larger cross-sectional bending stiffness with a smaller diameter column limb.

[0004] After the curtain wall is installed, the existing multi-limb lattice steel pipe columns generally use a connecting structure to connect the curtain wall to the outside of the steel pipe column. However, due to the large overall weight of the curved curtain wall, the load weight on both sides of the connecting structure is not uniform, resulting in the bending resistance of the connecting structure is not ideal.

In addition, by filling a granular filling medium inside the hanging part, by adjusting the connecting part, the connecting part drives the hanging part to adjust the connection position with the curved curtain wall according to the actual working conditions. At the same time, when driving the hanging part to move the position, the connecting part can also squeeze the filling medium, so that the filling medium produces a reaction force on the inner wall of the hanging part, so as to improve the bending resistance and structural strength of the hanging part itself.

[0011] By adopting the above scheme, a strip groove is opened on the outside of the square steel column, so that when the height position of the lifting part needs to be adjusted up and down, the square steel column can slide up and down on one side of the L-shaped steel bar, and is threadedly connected to the corresponding square steel column by a bolt column, so that the square steel column can be adjusted in vertical height while tightening the square steel column, and the bolt column is used to generate pressure on the extrusion plate.

[0012] In one embodiment of the present application, the connecting member further comprises: A U-shaped steel bar, the other side of the L-shaped steel bar extends into the interior of the U-shaped steel bar, a threaded rod is provided inside the U-shaped steel bar, the threaded rod penetrates the U-shaped steel bar along the width direction of the U-shaped steel bar, and is threadedly fastened with the U-shaped steel bar and the L-shaped steel bar, the number of the threaded rods is at least two, and at least two of the threaded rods are arranged at intervals along the length direction of the U-shaped steel bar.

[0013] By adopting the above scheme, by threading the threaded rod with the U-shaped steel bar and the L-shaped steel bar, the L-shaped steel bar can adjust the horizontal position on the threaded rod, which makes it easy to adjust the horizontal position of the lifting part, so that the device can adjust the horizontal position of the lifting part according to the actual working conditions. In addition, by providing two threaded rods and fastening them to the L-shaped steel bar at the same time, the lifting part can improve the torsion resistance of the L-shaped steel bar while adjusting the horizontal position.

[0014] In one embodiment of the present application, the connecting member further comprises: Two fixing seats, the two fixing seats are assembled on the U-shaped steel bar and are spaced apart along the width direction of the U-shaped steel bar; Two threaded columns, the threaded columns correspond to the fixing seats one by one, one end of the threaded column is coaxially rotatably assembled on the fixing seat, and the thread directions of the two threaded columns are opposite.

[0015] By adopting the above solution, a fixing seat is set on the U-shaped steel bar, and a threaded column is threadedly connected inside the fixing seat. By rotating the two threaded columns at the same time, the threaded column can drive the lifting part to adjust its position in the front and rear directions while rotating. At the same time, the two threaded columns are used and the two threaded columns can be interlocked, thereby preventing the lifting part from rotating at the fixing seat.

[0016] In one embodiment of the present application, the first assembly includes: A connecting tie bar, the two ends of which are respectively connected and fixed to two adjacent steel pipe columns; An angle steel piece, one end of which is vertically assembled on the connecting tie bar, and the other end of which is fixedly connected to a square steel block, the square steel block is hollow inside, and a plurality of reinforcing ribs are arranged inside the square steel block, the other end of some of the threaded columns penetrates the square steel block and is threadedly connected to the square steel block, and the other end of some of the threaded columns conflicts with the reinforcing ribs close to the threaded columns; A supporting steel frame, wherein both ends of the supporting steel frame are respectively connected and fixed to the angle steel pieces and the connecting tie bars.

By increasing the connection points, the device can be more stable when connected to the curtain wall. At the same time, when the threaded column is screwed into the square steel block, the reinforcing ribs inside the square steel block can conflict with the threaded column, thereby preventing the hanging part from rotating around the threaded rod as the axis, providing torsion resistance.

At the same time, the rubber protrusion on the inside of the center through hole can provide a certain resistance, reducing the possibility of the threaded column rotating. At the same time, the interaction force between the side wall of the circular through hole and the threaded column is utilized to further improve the clamping and limiting ability of the reinforcing rib on the threaded column.

[0021] In one embodiment of the present application, a plurality of strip-shaped cavities are formed on the inner wall of the steel pipe column. The strip-shaped cavities extend along the length direction of the steel pipe column, and shock-absorbing strips are embedded in the strip-shaped cavities.

[0022] By arranging shock-absorbing strips inside the steel pipe column, the structural strength inside the steel pipe column is strengthened, and at the same time, compared with a solid steel pipe column, the material used for the steel pipe column is saved to a certain extent.

[0023] In one embodiment of the present application, the connecting member includes: Two U-shaped steel frames, the opening directions of the two U-shaped steel frames are opposite to each other, one side of the U-shaped steel frame is slidably assembled in the strip groove, and is threadedly connected with the square steel column through a bolt column, and the other side of the U-shaped steel frame is against the inner walls of both sides of the U-shaped steel bar.

[0024] By setting up a U-shaped steel frame, using the other side of the U-shaped steel frame to support the inner walls of both sides of the U-shaped steel bar, and using the interaction force between the U-shaped steel frame and the U-shaped steel bar, the possibility of the U-shaped steel frame shifting sideways inside the U-shaped steel bar is reduced.

[0025] In one embodiment of the present application, a reinforcing rod is provided inside the U-shaped steel bar, one end of the reinforcing rod passes through one side of the U-shaped steel bar and extends along the other side of the U-shaped steel bar until it contacts the inner wall of the other side of the U-shaped steel bar, the other end of the reinforcing rod is rotatably connected to a nut, and the nut is threadedly connected to the U-shaped steel bar, a key bar extending along the length direction of the reinforcing rod is provided in the middle of the reinforcing rod, and a key groove corresponding to the position of the key bar is provided in the middle of the U-shaped steel frame.

[0026] By setting a reinforcing rod, one end of the reinforcing rod is used to penetrate the U-shaped steel bar and the U-shaped steel frame, and a nut is set at the other end of the reinforcing rod, so that the reinforcing rod is more convenient to assemble, and a key bar extending along the length direction of the reinforcing rod itself is set outside the reinforcing rod. Through the cooperation between the key bar and the key slot, the U-shaped steel frame will not deflect with the reinforcing rod as the axis, and the U-shaped steel frame and the U-shaped steel bar will conflict with each other, thereby avoiding the possibility of the U-shaped steel frame sliding sideways.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting a hoisting part with a hollow interior and setting a filling medium inside the hoisting part, the L-shaped steel bar is connected to the hoisting part by a bolt column, so that the bolt column can squeeze the pressure plate while being threadedly connected with the hoisting part, and then squeeze the filling medium, so that the filling medium can exert a uniform force on the side wall of the hoisting part, thereby preventing the hoisting part from bending, improving the structural strength of the hoisting part, and also making the hoisting part use less material and higher economic benefits.

[0028] 2. By setting up the cooperation of L-shaped steel bars, U-shaped steel bars and threaded columns, the square steel column can be adjusted in all directions according to the actual working conditions. In addition, when tightening, the mutual locking of the two threaded rods is used to avoid the deflection of the square steel column in the vertical direction, and the mutual locking of the two threaded columns is used to avoid the deflection of the square steel column in the horizontal direction, thereby further improving the installation stability of the square steel column.

[0029] 3. By setting the cooperation between the fixing rod and the key bar and the key slot, compared with the threaded rod, the fixing rod saves the trouble of screwing during assembly. At the same time, the engagement between the key bar and the key slot can well improve the torsion resistance of the U-shaped steel frame. In addition, when the U-shaped steel frame is connected by the fixing rod, only one fixing rod is needed, which saves more materials and enables the device to adjust its position. While ensuring its own torsion resistance, it saves more materials and has higher economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] See also Figure 3 , Figure 4 and Figure 5 The connecting member 3 also includes: a U-shaped steel bar 36, the other side of the L-shaped steel bar 32 extends to the inside of the U-shaped steel bar 36, and a threaded rod 37 is provided inside the U-shaped steel bar 36. The threaded rod 37 penetrates the U-shaped steel bar 36 along the width direction of the U-shaped steel bar 36 and is threadedly fastened with the U-shaped steel bar 36 and the L-shaped steel bar 32. The number of the threaded rods 37 is at least two, and at least two of the threaded rods 37 are arranged at intervals along the length direction of the U-shaped steel bar 36. By providing two threaded rods 37, the L-shaped steel bar 32 can adjust the horizontal position inside the U-shaped steel bar 36 while improving the torsion resistance of the L-shaped steel bar 32.

[0039] See also Figure 4 and Figure 5 The connecting member 3 also includes: two fixing seats 38 and two threaded columns 39. The two fixing seats 38 are assembled on the U-shaped steel bar 36 and are arranged at intervals along the width direction of the U-shaped steel bar 36. The threaded columns 39 correspond to the fixing seats 38 one by one. One end of the threaded column 39 is coaxially rotated and assembled on the fixing seat 38. The thread directions of the two threaded columns 39 are opposite.

At the same time, the two threaded columns 39 can be interlocked by using the two threaded columns 39, thereby preventing the hanging member 11 from rotating at the fixing seat 38.

[0040] See also Figure 1 , Figure 2 and Figure 3The first assembly part 21 includes: a connecting bar 211, an angle steel piece 212 and a supporting steel frame 215. The two ends of the connecting bar 211 are respectively connected and fixed to the two adjacent steel pipe columns 2.

In addition, when the threaded column 39 is screwed into the square steel block 213, the reinforcing ribs 214 inside the square steel block 213 can conflict with the threaded column 39, thereby preventing the hanging part 11 from rotating around the threaded rod 37 as the axis, providing torsion resistance.

[0042] Embodiment 2: The structure of Embodiment 2 is basically the same as that of Embodiment 1, except that: See also Figure 8 The reinforcing rib 214 includes circular through holes 2141 on both sides corresponding to the threaded columns 39. A plurality of rubber protrusions 2142 are arranged on the inner wall of the circular through hole 2141 along its own circumferential direction. By opening the circular through hole 2141 inside the reinforcing rib 214, after one end of the threaded column 39 is screwed into the square steel block 213, the threaded column 39 and the center through hole are engaged with each other, so that the hanging part 11 cannot rotate with the threaded rod 37 as the axis. At the same time, the rubber protrusion 2142 can provide a certain resistance to reduce the possibility of the threaded column 39 rotating.

[0043] Embodiment 3: The structure of Embodiment 3 is substantially the same as that of Embodiment 1, except that: See also Figure 7 The inner wall of the steel pipe column 2 is provided with a plurality of strip cavities 23, and the strip cavities 23 extend along the length direction of the steel pipe column 2. Shock-absorbing strips 24 are embedded in the strip cavities 23, which strengthen the structural strength inside the steel pipe column 2 and save the material of the steel pipe column 2 to a certain extent compared with the solid steel pipe column 2.

[0044] The shock-absorbing strips 24 may be wooden strips.

One end of the reinforcement rod 361 penetrates the U-shaped steel bar 36 and the U-shaped steel frame 310, and a nut 362 is provided at the other end of the reinforcement rod 361, so that the reinforcement rod 361 is more convenient to assemble. At the same time, a key bar 3611 extending along the length direction of the reinforcement rod 361 is provided outside the reinforcement rod 361. Through the cooperation between the key bar 3611 and the key slot, the U-shaped steel frame 310 will not deflect with the reinforcement rod 361 as the axis. At the same time, the U-shaped steel frame 310 and the U-shaped steel bar 36 conflict with each other, thereby avoiding the possibility of the U-shaped steel frame 310 sliding sideways.

[0046] In summary, when the output height of the hoisting member 11 needs to be adjusted, the bolt column 35 is removed, and the square steel column 111 is allowed to slide on the L-shaped steel bar 32. When the square steel column 111 slides to a suitable distance, the bolt column 35 is re-tightened. At this time, one end of the bolt column 35 is inserted into the square steel column 111 to apply pressure to the reinforcing plate. The reinforcing plate can squeeze the filling medium 31, so that the filling medium 31 can squeeze the side wall of the square steel column 111 to prevent the square steel column 111 from bending. When the horizontal position of the hanging member 11 needs to be adjusted, the threaded rod 37 is rotated so that the threaded rod 37 can drive the hanging member 11 to move inside the U-shaped steel bar 36 along the width direction of the U-shaped steel bar 36, so that the U-shaped steel bar 36 can adjust the distance in the horizontal position; When the front-to-back position of the hanging component 11 needs to be adjusted, the threaded column 39 is rotated to drive the position of the U-shaped steel bar 36 in the front-to-back direction, thereby adjusting the position of the hanging component 11 in the front-to-back direction.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
