Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building components, in particular to an anchoring assembly and a steel tube concrete column with the anchoring assembly. Background Art
[0002] Concrete-filled steel tube components, also known as steel tube concrete columns, have been widely used in the construction industry due to their superior strength, ductility, aesthetics, bearing capacity and ease of construction. The performance of steel tube concrete columns mainly depends on the composite effect between the outer steel tube and the inner concrete. The outer steel tube provides sufficient restraint effect for the concrete core, while the filled concrete core delays the occurrence of local buckling of the outer steel tube.
[0003] During the construction process, steel beams need to be connected to steel tube concrete columns to form a building frame. Usually, steel beams are connected to the outer steel pipes of steel tube concrete columns by welding. However, the quality of welding at the construction site depends closely on the experience of the workers and the temperature and humidity conditions at the construction site, which leads to unstable welding quality, thus affecting the quality of the stable connection between the steel beam and the outer steel pipe of the steel tube concrete column, and increasing the work intensity of the workers, resulting in low construction efficiency, and both the steel tube concrete column and the steel beam cannot be reused.
[0004] In order to avoid the adverse effects of welding, the existing method is to open a through hole in the outer steel pipe of the steel tube concrete column. When installing the steel beam, the worker needs to hold a drilling device to drill the corresponding position of the concrete core of the steel tube concrete column and the through hole of the outer steel pipe to form a blind hole at the corresponding position of the concrete core and the through hole, and place an expansion sleeve in the blind hole, and then pass the threaded end of the bolt through the connecting wall of the steel beam and the through hole of the outer steel pipe to connect with the expansion sleeve, so as to connect the steel beam to the steel tube concrete column. However, the quality of the worker holding the drilling equipment to drill the corresponding position of the concrete core and the through hole depends on the worker's experience. The blind hole formed by the drilling has an offset phenomenon, which affects the coaxiality of the blind hole and the through hole, thereby affecting the connection stability of the steel beam and the steel tube concrete column, and increases the work intensity of the workers. The construction efficiency is low, and the drilling operation causes damage to the concrete core. When reused, the old expansion sleeve needs to be taken out and a new expansion sleeve is put in, which makes the disassembly and assembly operation of reuse complicated, and the removal operation of the old expansion sleeve causes pull-out damage to the concrete core.

[0038] See also Figures 1 to 8 The present embodiment discloses a steel tube concrete column, comprising a steel tube 10 and an anchor assembly 15. A through hole 111 is formed through the circumferential wall 11 of the steel tube 10. The anchor assembly 15 comprises a first anchor block 151 and a first fastener 154. A first threaded hole 1512 is formed on the first end surface of the first anchor block 151. The threaded rod of the first fastener 154 is detachably threadedly connected to the first threaded hole 1512 of the first anchor block 151. In the present embodiment, the first anchor block 151 can be inserted into the circumferential wall 11 of the steel tube 10 through the through hole 111 of the steel tube 10. The rod section of the first fastener 154 is inserted into the through hole 111 of the steel tube 10 and can be rotatably and / or movably arranged relative to the through hole 111. Furthermore, the first fastener 154 of the present embodiment can drive the first anchor block 151 located inside the circumferential wall 11 of the steel pipe 10 to rotate and / or move, so that the abutting end face 1514 of the first end face of the first anchor block 151 protruding from the first threaded hole 1512 abuts against the inner wall surface of the circumferential wall 11 of the steel pipe 10, and the head of the first fastener 154 can abut against the outer wall surface of the circumferential wall 11 of the steel pipe 10. In addition, the concrete 12 is filled inside the circumferential wall 11 of the steel pipe 10 to restrict the first anchor block 151 whose abutting end face 1514 abuts against the inner wall surface of the circumferential wall 11 inside the circumferential wall 11 of the steel pipe 10, and the steel beam 13 can be detachably threadedly connected to the first threaded hole 1512 of the first anchor block 151 restricted inside the circumferential wall 11 of the steel pipe 10 by the first fastener 154 or the second fastener 14.
[0039] During the construction of the steel tube concrete column in this embodiment, the specific construction method of the steel tube concrete column includes:
[0040] First, the first anchor block 151 of the anchor assembly 15 is inserted into the interior of the circumferential wall 11 of the steel pipe 10 through the through hole 111 on the circumferential wall 11 of the steel pipe 10. At this time, the threaded rod of the first fastener 154 of the anchor assembly 15 is threadedly connected with the first threaded hole 1512 of the first anchor block 151, so that the worker can grasp the first fastener 154 of the anchor assembly 15 to quickly insert the first anchor block 151 of the anchor assembly 15 through the through hole 111 on the circumferential wall 11 of the steel pipe 10 into the interior of the circumferential wall 11 of the steel pipe 10, which is convenient for the worker to operate;
[0041] Next, the worker grasps the first fastener 154 of the anchor assembly 15 to control the first fastener 154 of the anchor assembly 15 to rotate and / or move, so as to drive the first anchor block 151 located inside the circumferential wall 11 of the steel pipe 10 to rotate and / or move, so that the abutting end surface 1514 of the first anchor block 151 abuts against the inner wall surface of the circumferential wall 11 of the steel pipe 10;
[0042] Subsequently, the worker places the head of the first fastener 154 of the anchor assembly 15 against the outer wall surface of the circumferential wall 11 of the steel pipe 10 to fasten the anchor assembly 15 as a whole to the circumferential wall 11 of the steel pipe 10. Specifically, the gap between the first fastener 154 and the through hole 111 may be filled with a sealant, so that the inner cavity of the circumferential wall 11 of the steel pipe 10 is in a sealed state, thereby preventing the subsequent concrete 12 from overflowing at the through hole 111;
[0043] Further, the concrete 12 is filled into the circumferential wall 11 of the steel pipe 10 to restrict the first anchor block 151 whose abutting end face 1514 abuts against the inner wall surface of the circumferential wall 11 to the inside of the circumferential wall 11 of the steel pipe 10, so that the first anchor block 151 of the anchor assembly 15 is firmly embedded in the concrete 12 filled in the circumferential wall 11 of the steel pipe 10;
[0044] Afterwards, the first fastener 154 of the anchor assembly 15 is removed from the first anchor block 151 that is restrained by the concrete 12 inside the circumferential wall 11;
[0045] Then, the steel beam 13 is threadedly connected to the first threaded hole 1512 of the first anchor block 151 confined inside the circumferential wall 11 of the steel pipe 10 through the first fastener 154 or the second fastener 14 .
[0046] Therefore, the steel tube concrete column of this embodiment is pre-embedded with an anchor component 15 before pouring the inner core of the concrete 12. After the concrete 12 is filled into the circumferential wall 11 of the steel tube 10 of the steel tube concrete column, the first anchor block 151 of the pre-embedded anchor component 15 can be firmly confined inside the circumferential wall 11 of the steel tube 10, so that the first anchor block 151 of the anchor component 15 is firmly embedded in the concrete 12 filled inside the circumferential wall 11 of the steel tube 10, and the steel beam 13 can be threadedly connected with the first threaded hole 1512 of the first anchor block 151 confined inside the circumferential wall 11 of the steel tube 10 through the first fastener 154 or the second fastener 14. Among them, the abutting end face 1514 of the first anchor block 151 of the anchor assembly 15 of the present embodiment abuts against the inner wall surface of the circumferential wall 11 of the steel pipe 10, which can improve the rigidity, compressive bearing capacity and anchoring effect of the connection between the steel pipe concrete column and the steel beam 13, thereby improving the tightness, stability, structural rigidity and strength, compressive bearing capacity and earthquake resistance of the connection position between the steel pipe concrete column and the steel beam 13. Moreover, the entire construction process of the steel pipe concrete column of the present embodiment can achieve a fastened connection with the steel beam 13 without the need for workers to weld or drill holes. During the installation of the steel beam 13, it is only necessary to remove the first fastener 154 from the first anchor block 151 restricted by the concrete 12 inside the circumferential wall 11, and then the steel beam 13 can be threadedly connected to the first threaded hole 1512 of the first anchor block 151 restricted inside the circumferential wall 11 of the steel pipe 10 through the first fastener 154 or the second fastener 14. During the removal of the steel beam 13, it is only necessary to remove the first fastener 154 from the first anchor block 151 restricted by the concrete 12 inside the circumferential wall 11. After the fastener 154 or the second fastener 14 is removed, the steel beam 13 can be removed from the steel tube concrete column, and the first fastener 154 can be threadedly connected to the first threaded hole 1512 of the first anchor block 151 confined inside the circumferential wall 11 of the steel tube 10, so as to prevent dust or debris from entering the first threaded hole 1512 of the first anchor block 151 confined inside the circumferential wall 11 of the steel tube 10 and affecting subsequent reuse, so that the disassembly and assembly operation of the steel tube concrete column and the steel beam 13 is flexible and simple, thereby achieving the purpose of reuse and saving resources. Therefore, the steel tube concrete column of this embodiment improves the bearing capacity of the steel tube concrete column while also improving the convenience of construction.
[0047] Combination Figure 1 , which is an implementation method of the steel pipe 10 and the steel beam 13 of this embodiment, that is, the circumferential wall 11 of the steel pipe 10 is set as a flat wall, so that the abutting end face 1514 of the first anchor block 151 and the inner wall surface of the circumferential wall 11 are flat surfaces adapted to abut, and the connecting wall of the steel beam 13 and the outer wall surface of the circumferential wall 11 are also flat surfaces adapted to abut, so that the steel pipe 10 of this embodiment is a rectangular steel pipe 10, and correspondingly, the abutting end face 1514 of the first anchor block 151 and the flat surface of the connecting wall of the steel beam 13 are adapted.
[0048] See also Fig.15 and Fig.16, which is another implementation of the steel pipe 10' and the steel beam 13' of this embodiment, that is, the circumferential wall 11' of the steel pipe 10' is set as an arc-shaped wall, so that the abutting end face 1514 of the first anchor block 151 and the inner wall surface of the circumferential wall 11 are adapted to abut with an arc-shaped surface, and the connecting wall 131' of the steel beam 13' and the outer wall surface of the circumferential wall 11 are also adapted to abut with an arc-shaped surface, so that the steel pipe 10' of this embodiment is an arc-shaped steel pipe, and correspondingly, the abutting end face 1514 of the first anchor block 151 and the arc-shaped surface of the connecting wall 131' of the steel beam 13' are adapted.
[0049] See also Figures 17 to 19 In this embodiment, the through hole 111 of the steel pipe 10 is polygonal or elliptical, and the shape of the cross section of the first anchor block 151 perpendicular to the axial direction of the first threaded hole 1512 is adapted to the shape of the through hole 111, so that the first anchor block 151 can smoothly pass through the through hole 111 of the steel pipe 10 and be inserted into the circumferential wall 11 of the steel pipe 10. Rotating and / or moving the first anchor block 151 located inside the circumferential wall 11 can make the abutting end face 1514 of the first anchor block 151 abut against the inner wall surface of the circumferential wall 11, thereby preventing the first anchor block 151 from escaping from the through hole 111 of the steel pipe 10, and ensuring that the first anchor block 151 is firmly restricted inside the circumferential wall 11 of the steel pipe 10 when pouring concrete 12. In addition, see Fig. 20 In this embodiment, the through hole 111 of the steel pipe 10 is arranged in a circular shape, and the shape of the cross section of the first anchor block 151 perpendicular to the axial direction of the first threaded hole 1512 is adapted to the shape of the through hole 111, so that after the first anchor block 151 passes through the through hole 111 of the steel pipe 10 and is inserted into the circumferential wall 11 of the steel pipe 10, the first anchor block 151 located inside the circumferential wall 11 is moved, and the abutting end face 1514 of the first anchor block 151 can also abut against the inner wall surface of the circumferential wall 11. Therefore, the shape of the through hole 111 and the axial cross-section of the first anchor block 151 perpendicular to the first threaded hole 1512 is not restricted, as long as the first anchor block 151 can pass through the through hole 111 of the steel pipe 10 and be inserted into the circumferential wall 11 of the steel pipe 10, and the first anchor block 151 located inside the circumferential wall 11 can be rotated and / or moved so that the abutting end face 1514 of the first anchor block 151 abuts against the inner wall surface of the circumferential wall 11.
[0050] Specifically, the rod section of the first fastener 154 of this embodiment is a partial rod section of the threaded rod, and the head is a nut. The nut and the threaded rod can be detachably threaded, and the nut can abut on the outer wall surface or the connecting wall 131 of the steel beam 13; or, the first fastener 154 of this embodiment is a first bolt. And, the second fastener 14 of this embodiment is a second bolt. Further, the rod section of the first fastener 154 of this embodiment is sleeved with a first gasket 155, and the first gasket 155 abuts on the outer wall surface of the circumferential wall 11 or between the connecting wall 131 of the steel beam 13 and the head of the first fastener 154, and the rod portion of the second fastener 14 is sleeved with a second gasket 141, and the second gasket 141 abuts between the connecting wall 131 of the steel beam 13 and the shoulder of the second fastener 14, thereby improving the stability of the locking. Furthermore, the first gasket 155 and the second gasket 141 can fully cover the through hole 111 to prevent the through hole 111 from being exposed and affecting the appearance.
[0051] Combination Figures 3 to 7 In this embodiment, the anchor assembly 15 further includes a second anchor block 153 and a connecting rod 152. The first anchor block 151 is provided with a second threaded hole 1513 at a second end face that is arranged opposite to the first end face of the first anchor block 151 in the axial direction of the first threaded hole 1512. The second anchor block 153 is provided with a third threaded hole 1531 at an end face that is close to the first anchor block 151. The first threaded end of the connecting rod 152 is detachably threadedly connected to the second threaded hole 1513, and the second threaded end of the connecting rod 152 is detachably threadedly connected to the third threaded hole 1531.
