TECHNICAL FIELD

[0001] The utility model relates to a special-shaped column, more particularly, it relates to a multi-limb lattice special-shaped column. BACKGROUND

[0002] The multi-limb lattice special-shaped column refers to a column section composed of multiple small wall limbs, forming L-shaped, T-shaped, cross-shaped or even Z-shaped combined section columns, the emergence of the multi-limb lattice special-shaped column greatly improves the building aesthetics of steel structures compared with concrete structures, and makes up for the deficiency in space utilization, so that the steel structure residence reaches the same level as the concrete residence in use function, since it is connected by multiple small limb pieces, the flexibility is strong, the main body of the multi-limb lattice special-shaped column is usually shaped according to the steel structure, but it is found in actual use that the limb piece will be extended locally in the finishing process or the re-decoration according to the actual demand, so the reinforcing steel bars cannot be extended out as a support fixed structure, relying on the external frame auxiliary fixing is time-consuming and laborious, therefore, a multi-limb lattice special-shaped column is needed, which can quickly fix the limb piece.

[0003] In view of the above reasons, how to quickly fix the limb piece is the problem considered by the present application. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies in the prior art, a multi-limb lattice special-shaped column is provided, which can quickly fix the limb piece.

[0005] To achieve the above purpose, the following technical scheme is provided: a multi-limb lattice special-shaped column, comprising a column body, a first connecting assembly, a limb piece and a second connecting assembly, the column body is provided with a threaded hole, the second connecting assembly comprises a threaded rod, the limb piece is provided with a through hole and a receiving cavity, the through hole communicates the inside and outside of the receiving cavity, and the threaded rod is arranged in the receiving cavity and passes through the through hole;

[0006] When installing the limb piece, the threaded rod is threadedly connected with the threaded hole through the first connecting assembly.

[0007] In summary, the technical scheme has the following beneficial effects: in use, the multi-limb lattice special-shaped column is usually decorated according to actual design and pouring is completed, so the re-decoration involved is essentially the extension of the limb, the limb is fixed in position by external mounting frames in use, which on the one hand leads to too large actual construction space occupation, greatly slowing down the construction efficiency of re-decoration construction, and on the other hand the connection between the limb and the column cannot be stabilized by steel bars, so that the stability directly depends on the stability of the external mounting frames, even if screws are used for connection, the small screws are prone to damage at the screw connection due to the lever principle, and the large gap directly affects subsequent pouring, therefore, the multi-group screw holes and screw rods are arranged in cooperation to avoid loose connection, and the stress is transferred to the screw rods to avoid the gap caused by the damage of the connection due to the lever principle.

[0008] The screw holes and the screw rods are connected by mutual engagement between the threads, are not prone to loosening and have good anti-seismic performance, the screw rods can bear the tensile force in the non-thread extension direction, when the limb is installed, the two ends of the limb are the two thread extension directions, but because the two ends of the limb are connected to the column or the wall surface, the bearing capacity of the thread itself does not need to be worried about, so the limb connected by this connection mode can bear large load, and the fastening mode of the threaded connection is relatively fixed and is not prone to loosening after long-term use.

[0009] In addition, the first connecting assembly, the limb and the second connecting assembly can be produced by other flow line production mode to reduce production cost and improve production efficiency, the column only needs to be drilled with screw holes when needed, and the first connecting assembly, the limb and the second connecting assembly can be combined after being transported to the construction site, so as to improve the overall construction efficiency.

[0010] The first connecting assembly and the second connecting assembly are arranged to connect the column and the limb, the connection tightness is enhanced by the threaded connection of the screw holes and the screw rods, and the connection can be completed only by rotating the screw rod, so that the limb can be quickly fixed.

[0023] Referring to Figures 1-4 As shown in the figure, the multi-limb lattice-shaped special-shaped column comprises a column body 1, a first connecting assembly 2, a limb 3 and a second connecting assembly 4. The column body 1 is provided with a threaded hole 11. The second connecting assembly 4 comprises a threaded rod 41. The limb 3 is provided with a through hole 31 and an accommodating cavity 32.

[0024] When the limb 3 is installed, the threaded rod 41 is threadedly connected with the threaded hole 11 through the first connecting assembly 2.

[0025] The multi-limbed lattice-shaped special-shaped column is usually decorated according to the actual design and pouring during use, so the re-decoration involved is essentially the extension of the limb 3, the limb 3 is fixed in position by the external frame during use, but this will on the one hand cause the actual construction to occupy too much space, greatly slowing down the construction efficiency of the re-decoration construction, and on the other hand, the connection between the limb 3 and the column 1 cannot be stabilized by steel bars, so that the stability directly depends on the stability of the external frame, even if a screw connection is used, the small screw itself is prone to damage due to the lever principle, resulting in a large gap that directly affects the subsequent pouring, so the utility model is characterized in that a plurality of threaded holes 11 and threaded rods 41 are arranged in cooperation to avoid loose connection, and the stress is transferred to the threaded rod 41 to avoid the gap caused by the damage of the connection due to the lever principle.

[0026] The threaded hole 11 and the threaded rod 41 are connected by the mutual engagement between the threads, are not easy to loosen, and have good anti-seismic performance, the threaded rod 41 can bear the tensile force in the non-threaded extension direction, the two ends of the limb 3 are the two threaded extension directions during installation, but since the two ends of the limb 3 are connected to the column 1 or the wall surface, the bearing capacity of the thread itself does not need to be worried about, so the limb 3 connected in this way can bear a large load, and the fastening way of the threaded connection is relatively fixed, and is not easy to loosen after long-term use.

[0027] In addition, the first connecting assembly 2, the limb 3 and the second connecting assembly 4 can be produced by other assembly line to reduce production cost and improve production efficiency, and the column 1 only needs to drill threaded holes 11 when needed, and the first connecting assembly 2, the limb 3 and the second connecting assembly 4 can be combined after being transported to the construction site, thereby improving the overall construction efficiency.

[0028] The utility model discloses a first connecting assembly 2 and second connecting assembly 4 are arranged to connect the column 1 and the limb 3, the threaded hole 11 and the threaded rod 41 are connected in the threaded way to enhance the connection tightness, and only need to rotate the threaded rod 41 to complete the connection, so that the limb 3 can be quickly fixed.

[0029] Further, the limb 3 is also provided with a containing groove 33, the containing cavity 32 and the containing groove 33 are communicated, the second connecting assembly 4 further includes a rotating rod 42, a stabilizing disc 43 and a resisting piece 44, the two ends of the rotating rod 42 are fixedly connected with the stabilizing disc 43 and the resisting piece 44 respectively, the stabilizing disc 43 is fixedly connected with the threaded rod 41, the side wall of the stabilizing disc 43 is slidably connected with the inner wall of the containing cavity 32, and the resisting piece 44 is used for adapting the tool for driving the rotating rod 42 to rotate.

[0030] The stability of the threaded rod 41 is maintained by the abutting of the stabilizing disc 43 against the accommodating cavity 32, and the threaded rod 41 is always in the accommodating cavity 32, the slot of the accommodating slot 33 is exposed, so when the threaded rod 41 needs to be rotated, the rotating rod 42 arranged in the accommodating slot 33 can be rotated, which can reduce the exposure of the threaded rod 41, and the rotating rod 42 can be driven to rotate by the abutting piece 44 of the matching tool, so that the limb 3 can be quickly fixed only when the matching tool is used, and safety is ensured.

[0031] Further, the first connecting assembly 2 comprises a mounting plate 21, a supporting piece 22, a connecting piece 23 and an abutting ring 24, the mounting plate 21 is provided with an opening 211 communicated with the threaded hole 11, the connecting piece 23 is fixedly connected with the abutting ring 24 and the supporting piece 22 at both ends respectively, and the supporting piece 22 is fixedly connected with the mounting plate 21;

[0032] When the limb 3 is installed, the connecting piece 23 extends into the accommodating cavity 32, and the abutting ring 24 abuts against the stabilizing disc 43.

[0033] The first connecting assembly 2 further comprises an abutting block 25 fixedly connected to the inner wall of the abutting ring 24;

[0034] When the limb 3 is installed, the abutting block 25 abuts against the threaded rod 41.

[0035] The connecting piece 23 is made of a material with toughness, and the connecting piece 23 is provided with a crease 231 for guiding the outward bending of the connecting piece 23;

[0036] When the threaded rod 41 moves towards the column 1, the stabilizing disc 43 abuts against the side surface of the abutting ring 24, the connecting piece 23 bends outwardly and abuts against the inner wall of the accommodating cavity 32.

[0037] The threaded rod 41 mainly maintains the close connection state after the installation of the limb 3 is completed, and when the limb 3 is used to fix a newly added column, the supporting force of the threaded rod 41 at one end of the limb 3 is insufficient, and the threaded rod 41 may be separated in the installation direction, so the connecting piece 23 which can be bent is arranged, the actual area of the bent connecting piece 23 can be increased, and a clamping effect can be formed together with the accommodating cavity 32, so that the limb 3 is prevented from being separated in the installation direction;

[0038] When the threaded rod 41 moves towards the column 1, since the threaded rod 41 is only supported by the stabilizing disc 43, it is difficult to be inserted into the threaded hole 11, so the abutting ring 24 and the abutting block 25 are arranged as the second supporting part, and during the continuous movement, the threaded rod 41 drives the stabilizing disc 43 to move, the abutting ring 24 moves due to the movement of the stabilizing disc 43, and then drives the connecting piece 23 to bend.

[0039] Further, the column 1 is further provided with a groove 12, and the mounting plate 21 is installed in the groove 12.

[0040] Due to the existence of the mounting plate 21, the limb 3 will be raised after installation is completed, and a certain crack will be generated in the middle, affecting subsequent pouring, therefore the groove 12 is arranged to hide the mounting plate 21, and meanwhile the aesthetic appearance is improved.

[0041] Further, the first connecting assembly 2 further comprises an L-shaped connecting plate 26, a first screw 27 and a second screw 28, the L-shaped connecting plate 26 abuts against the mounting plate 21 and the inner wall of the groove 12, the first screw 27 passes through the L-shaped connecting plate 26 and the mounting plate 21 and is connected to the inner wall of the groove 12, the second screw 28 passes through the L-shaped connecting plate 26 and is connected to the inner wall of the groove 12, and the extension direction of the first screw 27 and the extension direction of the second screw 28 are vertically arranged.

[0042] If the mounting plate 21 is fixed in only one direction with the column 1, the pressure of the shear force is concentrated on the first screw 27, and if the limb 3 is impacted, the impact force perpendicular to the extension direction of the first screw 27 can cause the first screw 27 to be cut off, causing the mounting plate 21 to be separated from the column 1, therefore the L-shaped connecting plate 26 and the second screw 28 are additionally arranged, the extension direction of the first screw 27 and the extension direction of the second screw 28 are vertically arranged, so that the mounting plate 21 can be fixed in two perpendicular directions, and the received impact force is effectively dispersed.

[0043] Further, the one end of the threaded rod 41 away from the stabilizing disc 43 is fixedly connected with an elastic member 45.

[0044] In order to prevent the movement of the threaded rod 41 from colliding with the abutting ring 24 and other components when misaligned, the elastic member 45 is connected on the threaded rod 41 to play a protective role.
