Description

Technical Field

[0001] The present application relates to the technical field of steel pipe column structures, and particularly to a multi-limb lattice steel pipe column structure for assembling an arc-shaped curtain wall. Background Art

[0002] A multi-limb lattice steel pipe column is a composite structure formed by connecting multiple steel pipe members through lacing members (such as lacing plates or lacing bars), and is widely used in building and bridge engineering. When in application, for its aesthetic property, an arc-shaped curtain wall is generally attached to the outside of the multi-limb lattice steel pipe column.

[0003] By arranging materials at positions far from the inertia axis, the multi-limb lattice steel pipe column can significantly enhance the bending resistance of the member under the same axial resistance condition, while saving materials. In addition, the structural form can obtain a larger sectional bending stiffness with a smaller diameter of the column limb.

[0004] After the existing multi-limb lattice steel pipe column is attached with a curtain wall, a connecting structure is generally used to connect the curtain wall to the outside of the steel pipe column. However, due to the large overall weight of the arc-shaped curtain wall, the load weights on both sides of the connecting structure are not uniform, thus resulting in an unsatisfactory bending resistance of the connecting structure. Summary of the Invention

[0005] The present application provides a multi-limb lattice steel pipe column structure for assembling an arc-shaped curtain wall, which can solve the problem that the connecting structure between the existing multi-limb lattice steel pipe column structure assembled with an arc-shaped curtain wall is difficult to balance material saving and ensuring its own bending strength.

[0006] The technical solution of the present application is as follows: A multi-limb lattice steel pipe column structure for assembling an arc-shaped curtain wall, comprising:

[0007] A columnar arc-shaped curtain wall, the arc-shaped curtain wall having a cross-section in the shape of a circle or a partial circle, and a plurality of internally hollow lifting members being arranged along the circumferential direction of the inner wall of the arc-shaped curtain wall;

[0008] At least two steel pipe columns, at least two of the steel pipe columns being arranged inside the arc-shaped curtain wall, a first fitting being provided between adjacent two of the steel pipe columns, a second fitting being provided on a side of the steel pipe column close to the arc-shaped curtain wall, the first fitting and some of the lifting members being connected by a connecting member, the second fitting and some other of the lifting members being connected by a connecting member, the connecting member fastening the lifting members to the arc-shaped curtain wall, and granular filling medium being filled inside the lifting members, and the connecting member adjusting the position of the lifting members while squeezing the filling medium, so that the filling medium generates a acting pressure on the lifting members.

[0009] By adopting the above solution, by setting the first fitting and the second fitting and assembling them on the steel pipe column and between two adjacent steel pipe columns respectively, the arc-shaped curtain wall can evenly bear the weight on the steel pipe column. In addition, by filling granular filling medium inside the lifting member and adjusting the connecting member, the connecting member can drive the lifting member to adjust the connection position with the arc-shaped curtain wall according to the actual working conditions. At the same time, when the connecting member drives the lifting member to move, it can also squeeze the filling medium, so that the filling medium generates a reaction force on the inner wall of the lifting member to improve the bending resistance and structural strength of the lifting member itself.

[0010] In one embodiment of the present application, the lifting member includes:

[0011] Two internally hollow square steel columns, the filling medium is arranged inside the square steel columns, and one end of the square steel columns is fixedly connected to the arc-shaped curtain wall by bolts;

[0013] By adopting the above solution, by setting the pressure plate, when the connecting member is connected to the lifting member, one end extends into the square steel column and squeezes the pressure plate, thus realizing that when the connecting member is connected to the lifting member, it can squeeze the pressure plate and make the pressure plate squeeze the filling medium, so that the filling medium generates pressure on the inner wall of the square steel column.

[0016] By adopting the above solution, by opening strip-shaped grooves on the outside of the square steel columns, when it is necessary to adjust the height position of the lifting member up and down, the square steel columns can slide up and down on one side of the L-shaped steel bars, and the square steel columns are threadedly connected to the corresponding square steel columns by bolt columns, so as to realize the adjustment of the position of the square steel columns in the vertical height while fastening the square steel columns, and the bolt columns generate pressure on the extrusion plate.

[0017] In one embodiment of the present application, the connecting member further includes:

[0018] U-shaped steel bars, the other side of the L-shaped steel bar extends into the U-shaped steel bar, a threaded rod is arranged inside the U-shaped steel bar, the threaded rod penetrates through the U-shaped steel bar along the width direction of the U-shaped steel bar, and is threadedly fastened to 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.

[0019] By adopting the above scheme, by threadedly connecting the threaded rod with the U-shaped steel bar and the L-shaped steel bar, the L-shaped steel bar can adjust its position in the horizontal direction on the threaded rod, so as to facilitate the adjustment of the position of the hoisting member in the horizontal direction, so that the device can adjust the horizontal position of the hoisting member according to the actual working conditions. In addition, by setting the threaded rod to two and simultaneously fastening and assembling it on the L-shaped steel bar, the torsional resistance of the L-shaped steel bar is improved while the horizontal position of the hoisting member is adjusted.

[0020] In one embodiment of the present application, the connecting member further includes:

[0021] Two fixing seats, the two fixing seats are assembled on the U-shaped steel bar and are arranged at intervals along the width direction of the U-shaped steel bar;

[0022] 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.

[0023] By adopting the above scheme, by arranging fixing seats on the U-shaped steel bar and threadedly connecting threaded columns inside the fixing seats, by simultaneously rotating the two threaded columns, the threaded columns can drive the hoisting member to adjust its position in the front-back direction while rotating, and at the same time, by using the two threaded columns, the two threaded columns can be interlocked to prevent the hoisting member from rotating on its own at the fixing seat.

[0024] In one embodiment of the present application, the first fitting includes:

[0025] Connecting batten plates, both ends of the connecting batten plates are fixedly connected to two adjacent steel pipe columns respectively;

[0029] A connecting steel frame, one side of which is fixedly assembled on the steel pipe column, and the other end of the other part of the threaded column passes through the connecting steel frame and is threadedly connected to the connecting steel frame.

[0030] By adopting the above solution, by arranging the first assembly part and the second assembly part, and arranging the two on the steel pipe column and between the steel pipe columns respectively, the steel pipe column and the curved curtain wall can be connected at multiple positions through the connecting parts. 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 interfere with the threaded column, thereby preventing the hanging part from rotating about the threaded rod as the axis, thereby providing torsion resistance.

[0031] In one embodiment of the present application, the reinforcing rib includes circular through holes on both sides corresponding to the threaded columns, and a plurality of rubber protrusions are provided on the inner wall of the circular through hole at intervals along its circumference.

[0032] By adopting the above solution, a circular through hole is opened inside the reinforcing rib, so that after one end of the threaded column is screwed into the square steel block, the other end of the threaded column can extend into the center through hole, so that the lifting part cannot rotate with the threaded rod as the axis. 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.

[0033] In one embodiment of the present application, a plurality of strip-shaped cavities are provided 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.

[0034] By arranging shock-absorbing strips inside the steel pipe column, the structural strength of the steel pipe column is enhanced, and at the same time, the material used for the steel pipe column is saved to a certain extent compared with a solid steel pipe column.

[0035] In one embodiment of the present application, the connecting member includes:

[0036] 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 to 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.

[0037] 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 utilizing 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.

[0038] In one embodiment of the present application, a reinforcing rod is provided inside the U-shaped steel bar. One end of the reinforcing rod penetrates through one side of the U-shaped steel bar and extends along the other side of the U-shaped steel bar until it abuts against the inner wall of the other side of the U-shaped steel bar. A nut is rotatably connected to the other end of the reinforcing rod, and the nut is threadedly connected to the U-shaped steel bar. A key strip 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 strip is provided in the middle of the U-shaped steel frame.

[0039] By providing the reinforcing rod, with one end of the reinforcing rod penetrating through the U-shaped steel bar and the U-shaped steel frame and a nut being provided at the other end of the reinforcing rod, the assembly of the reinforcing rod is more convenient. At the same time, a key strip extending along the length direction of the reinforcing rod is provided outside the reinforcing rod. Through the cooperation between the key strip and the key groove, the U-shaped steel frame will not deflect around the reinforcing rod, and at the same time, the U-shaped steel frame and the U-shaped steel bar are in contact with each other, avoiding the possibility of the U-shaped steel frame slipping sideways.

[0040] In summary, the present application includes at least one of the following beneficial technical effects:

[0041] 1. By providing a hoisting member with a hollow interior and a filling medium inside the hoisting member, and connecting the L-shaped steel bar to the hoisting member using a bolt column, the bolt column can, while being threadedly connected to the hoisting member, squeeze the pressure plate, and further squeeze the filling medium, so that the filling medium can generate a uniform acting force on the side wall of the hoisting member, thereby avoiding the hoisting member from bending, improving the structural strength of the hoisting member, and also using less material for the hoisting member, with higher economic benefits.

[0042] 2. Through the cooperation of the L-shaped steel bar, the U-shaped steel bar and the threaded column, the square steel column can adjust its position in all directions according to the actual working conditions. In addition, when tightening, by the mutual locking of the two threaded rods, the deflection of the square steel column in the vertical direction is avoided, and by the mutual locking of the two threaded columns, the deflection of the square steel column in the horizontal direction is avoided, thereby further improving the installation stability of the square steel column.

[0043] 3. Through the cooperation between the fixed rod, the key strip and the key groove, compared with the threaded rod, the fixed rod saves the trouble of screwing during assembly. At the same time, the engagement between the key strip and the key groove can well improve the torsional resistance of the U-shaped steel frame. In addition, when connecting the U-shaped steel frame with the fixed rod, only one fixed rod is needed, which saves more materials. While enabling the device to adjust its position and ensuring its torsional resistance, it uses less materials and has higher economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0055] The following further describes in detail a multi-limb lattice steel pipe column structure for assembling a curved curtain wall provided by this application in conjunction with the attached Figures 1 - 10 drawings.

[0056] Example 1. Please refer to Figure 1 、 Figure 2 and Figure 3 . A multi-limb lattice steel pipe column structure for assembling a curved curtain wall provided in an embodiment of this application includes: a columnar curved curtain wall 1 and at least two steel pipe columns 2. The curved curtain wall 1 has a cross-section in the shape of a circle or a partial circle. A plurality of internally hollow lifting members 11 are arranged along the circumferential direction of the inner wall of the curved curtain wall 1. At least two of the steel pipe columns 2 are all arranged inside the curved curtain wall 1. A first fitting 21 is provided between two adjacent steel pipe columns 2. A second fitting 22 is provided on one side of the steel pipe column 2 close to the curved curtain wall 1. The first fitting 21 and a part of the lifting members 11 are connected by a connecting piece 3. The second fitting 22 and another part of the lifting members 11 are connected by a connecting piece 3. The connecting piece 3 fastens the lifting member 11 to the curved curtain wall 1. The interior of the lifting member 11 is filled with a granular filling medium 31. The connecting piece 3 adjusts the position of the lifting member 11 while squeezing the filling medium 31, so that the filling medium 31 generates a working pressure on the lifting member 11. By filling the granular filling medium 31 inside the lifting member 11, the connecting piece 3 can drive the lifting member 11 to adjust the connection position with the curved curtain wall 1 according to the actual working conditions. At the same time, the filling medium 31 can also be squeezed, so that the filling medium 31 generates a reaction force on the inner wall of the lifting member 11 to improve the bending resistance and structural strength of the lifting member 11 itself.

[0057] Among them, the filling medium 31 can be quartz sand.

[0058] Among them, when the number of steel pipe columns 2 is set to two, the top view of the multi-limb lattice steel pipe column structure is as shown in the attached drawings of the specification Figure 2 of this application.

[0059] Please refer to Figure 3 As shown in the figure, the hoisting member 11 includes: two square steel columns 111 with hollow interiors and a pressure plate 112. The filling medium 31 is disposed inside the square steel columns 111. One end of the square steel column 111 is fixedly connected to the arc-shaped curtain wall 1 by bolts. The pressure plate 112 is disposed inside the square steel column 111 and on one side of the filling medium 31 away from one end of the square steel column 111. One end of the connecting member 3 abuts against the pressure plate 112. By providing the pressure plate 112, when the connecting member 3 is connected to the hoisting member 11, one end of the connecting member 3 can squeeze the pressure plate 112, and the pressure plate 112 can squeeze the filling medium 31 to generate pressure on the inner wall of the square steel column 111, thereby improving the bending resistance.

[0060] Please continue to refer to Figure 3 、 Figure 4 and Figure 6 As shown in the figure, the connecting member 3 includes: two L-shaped steel bars 32. A strip-shaped groove 34 is formed on the end face of the other end of the square steel column 111. One side of the L-shaped steel bar 32 is slidably assembled in the strip-shaped groove 34. A plurality of threaded holes 33 are spaced along the length direction of the strip-shaped groove 34. A plurality of bolt columns 35 corresponding to the threaded holes 33 one by one are provided on the L-shaped steel bar 32, and the square steel column 111 is threadedly connected through the bolt columns 35. One end of the bolt column 35 extends into the square steel column 111 and abuts against the pressure plate 112. When it is necessary to adjust the height position of the hoisting member 11 up and down, the square steel column 111 can slide up and down on one side of the L-shaped steel bar 32, so that the square steel column 111 can be adjusted in position in the vertical height. At the same time, the bolt column 35 can be used to generate pressure on the extrusion plate.

[0061] Please refer to Figure 3 、 Figure 4 and Figure 5 As shown in the figure, the connecting member 3 further includes: a U-shaped steel bar 36. The other side of the L-shaped steel bar 32 extends into the U-shaped steel bar 36. 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 to 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 threaded rods 37 are arranged at intervals along the length direction of the U-shaped steel bar 36. By providing two threaded rods 37, while the L-shaped steel bar 32 can adjust the horizontal position inside the U-shaped steel bar 36, the torsional resistance of the L-shaped steel bar 32 can be improved.

[0062] Please refer to Figure 4 and Figure 5, the connecting member 3 further 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 and rotatably assembled on the fixing seat 38. The thread directions of the two threaded columns 39 are opposite. By rotating the two threaded columns 39 simultaneously, the threaded columns 39 can drive the lifting member 11 to adjust its position in the front-rear direction while rotating. At the same time, by using the two threaded columns 39, the two threaded columns 39 can be interlocked to prevent the lifting member 11 from rotating on its own at the fixing seat 38.

[0063] Please refer to Figure 1 , Figure 2 and Figure 3 , the first fitting 21 includes: a connecting brace 211, an angle steel member 212 and a support steel frame 215. The two ends of the connecting brace 211 are respectively fixedly connected to two adjacent steel pipe columns 2. One end of the angle steel member 212 is vertically assembled on the connecting brace 211, and the other end is fixedly connected to a square steel block 213. The inside of the square steel block 213 is hollow, and a plurality of reinforcing ribs 214 are provided inside the square steel block 213. The other ends of some of the threaded columns 39 penetrate through the square steel block 213 and are threadedly connected to the square steel block 213. The other ends of some of the threaded columns 39 are in contact with the reinforcing ribs 214 close to the threaded columns 39. The two ends of the support steel frame 215 are respectively fixedly connected to the angle steel member 212 and the connecting brace 211.

[0064] The second fitting 22 includes: a connecting steel frame 221. One side of the connecting steel frame 221 is fixedly assembled on the steel pipe column 2, and the other ends of some of the threaded columns 39 penetrate through the connecting steel frame 221 and are threadedly connected to the connecting steel frame 221. By providing the first fitting 21 and the second fitting 22, the steel pipe column 2 and the arc-shaped curtain wall 1 can be connected at multiple positions through the connecting member 3. In addition, when the threaded column 39 is screwed into the inside of the square steel block 213, the reinforcing ribs 214 inside the square steel block 213 can be in contact with the threaded column 39 to prevent the lifting member 11 from rotating on its own with the threaded rod 37 as the axis, providing torsional resistance.

[0065] Embodiment 2, the structure of Embodiment 2 is basically the same as that of Embodiment 1, and the difference is that:

[0066] Please refer to Figure 8, the reinforcing rib 214 includes circular through holes 2141 corresponding to the threaded posts 39 on both sides. A plurality of rubber protrusions 2142 are arranged at intervals along the circumferential direction of the inner wall of the circular through hole 2141. By providing the circular through holes 2141 inside the reinforcing rib 214, after one end of the threaded post 39 is screwed into the square steel block 213, the threaded post 39 is engaged with the central through hole, so that the lifting member 11 cannot rotate around the threaded rod 37. At the same time, the rubber protrusions 2142 can provide a certain amount of resistance, reducing the possibility of the threaded post 39 rotating on its own.

[0067] Embodiment 3, the structure of Embodiment 3 is basically the same as that of Embodiment 1, and the difference lies in:

[0068] Please refer to Figure 7 , a plurality of strip-shaped cavities 23 are formed in the inner wall of the steel pipe column 2. The strip-shaped cavities 23 extend along the length direction of the steel pipe column 2. Shock-absorbing strips 24 are embedded inside the strip-shaped cavities 23. While strengthening the internal structural strength of the steel pipe column 2, compared with the solid steel pipe column 2, the material used for the steel pipe column 2 is saved to a certain extent.

[0069] Among them, the shock-absorbing strip 24 can be a wooden strip.

[0070] Embodiment 4, the structure of Embodiment 4 is basically the same as that of Embodiment 1, and the difference lies in:

[0071] Please refer to Figure 9 and Figure 10, the connecting member 3 includes: two U-shaped steel frames 310 with their opening directions facing away from each other. One side of each U-shaped steel frame 310 is slidably assembled in the strip-shaped groove 34 and is threadedly connected to the square steel column 111 through a bolt column 35. The other side of the U-shaped steel frame 310 abuts against the inner walls on both sides of the U-shaped steel strip 36. A reinforcing rod 361 is provided inside the U-shaped steel strip 36. One end of the reinforcing rod 361 penetrates through one side of the U-shaped steel strip 36 and extends along the other side of the U-shaped steel strip 36 until it abuts against the inner wall on the other side of the U-shaped steel strip 36. A nut 362 is rotatably connected to the other end of the reinforcing rod 361, and the nut 362 is threadedly connected to the U-shaped steel strip 36. A key strip 3611 extending along the length direction of the reinforcing rod 361 is provided in the middle of the reinforcing rod 361, and a key groove corresponding to the position of the key strip 3611 is provided in the middle of the U-shaped steel frame 310. By passing one end of the reinforcing rod 361 through the U-shaped steel strip 36 and the U-shaped steel frame 310 and providing a nut 362 at the other end of the reinforcing rod 361, the assembly of the reinforcing rod 361 is more convenient. At the same time, a key strip 3611 extending along the length direction of the reinforcing rod 361 is provided outside the reinforcing rod 361. Through the cooperation between the key strip 3611 and the key groove, the U-shaped steel frame 310 will not deflect around the reinforcing rod 361. At the same time, the U-shaped steel frame 310 abuts against the U-shaped steel strip 36, avoiding the possibility of the U-shaped steel frame 310 slipping sideways.

[0072] In summary, when it is necessary to adjust the output height of the lifting member 11, remove the bolt column 35 and make the square steel column 111 slide on the L-shaped steel strip 32. When it slides to an appropriate distance, tighten the bolt column 35 again. 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, and 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;

[0073] When it is necessary to adjust the horizontal position of the lifting member 11, by rotating the threaded rod 37, the threaded rod 37 can drive the lifting member 11 to move inside the U-shaped steel strip 36 along the width direction of the U-shaped steel strip 36, so that the U-shaped steel strip 36 can adjust the distance in the horizontal position;

[0074] When it is necessary to adjust the front-back position of the lifting member 11, by rotating the threaded column 39, the position of the U-shaped steel strip 36 in the front-back direction can be driven, and then the position of the lifting member 11 in the front-back direction can be adjusted. The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
