Description

Technical Field

[0001] The utility model belongs to the technical field of building protection and relates to a supporting device for inclined columns of a steel structure of a building. Background Art

[0002] Earthquake disaster investigations show that the expected "strong columns and weak beams" and "strong nodes and weak components" yield mechanisms of steel frame structures rarely occur. Instead, damage is concentrated at the column ends and node positions. When an earthquake occurs, the steel columns of buildings are prone to collapse. After the steel columns collapse, they are likely to cause damage to the surrounding personnel and finances. Severe cases may cause the building to collapse directly. Therefore, the steel columns need to be protected to prevent them from tilting and rotating at too large an angle during an earthquake, causing them to collapse directly. Utility Model Content

[0003] The utility model aims to provide a building steel structure inclined column support device in view of the problems existing in the prior art.

[0004] To this end, the utility model adopts the following technical solutions:

[0005] A device for supporting inclined columns of a steel structure of a building, comprising a horizontally arranged crossbeam, on which a vertically arranged steel column is arranged, one side of which is provided with an inclined support rod, the top end of the support rod is hinged to the upper part of the steel column, the middle part of the support rod is hinged to a first connecting rod, and the end of the first connecting rod away from the support rod is hinged to the crossbeam.

[0006] Furthermore, a rotating shaft is fixed to the top end of the first connecting rod, a through hole corresponding to the rotating shaft is provided in the middle of the support rod, the rotating shaft passes through the through hole, and a second connecting rod arranged parallel to the first connecting rod is fixed to the end of the rotating shaft away from the first connecting rod, the length of the second connecting rod is equal to that of the first connecting rod, and the bottom end of the second connecting rod is hinged to the crossbeam.

[0007] Furthermore, the rotating shaft is arranged horizontally.

[0008] Furthermore, the steel column is an I-beam.

[0009] Furthermore, a first pull rod is hinged at the middle of the support rod, a second pull rod is hinged at one end of the first pull rod away from the support rod, and an end of the second pull rod away from the first pull rod is hinged to the lower part of the steel column.

[0010] The beneficial effects of the utility model are as follows: a support rod is hingedly arranged on one side of the steel column, and the steel column, the support rod and the first connecting rod form a four-rod mechanism through the first connecting rod. For a prefabricated frame structure building, in a single-frame frame, when the steel column is tilted and rotated, the support rod can be rotated and unfolded relative to the steel column, and when the bottom end of the support rod contacts the crossbeam, the steel column can be supported to prevent the steel column from continuing to rotate and collapse; the first pull rod and the second pull rod can generate a tensioning force on the support rod in the direction of the column to prevent the angle between the support and the steel column from being too large, thereby improving the stability and safety of the structure and further improving the supporting effect; a safe passage can be formed between the steel column and the support rod, and the remaining layers can slowly tilt while keeping the overall structure without obvious damage, thereby ensuring the survival rate of people after the earthquake, the rapidity and safety of rescue.

[0015] The utility model is described in detail below with reference to the accompanying drawings:

[0016] like Figure 1 and 2As shown, a building steel structure inclined column support device is provided, which is a horizontally arranged cross beam 1, and a vertically arranged steel column 2 is arranged on the cross beam 1. The cross beam 1 and the steel column 2 are both conventional structures of existing buildings. The steel column 2 adopts an I-beam, and a support rod 3 is arranged obliquely on one side of the weak axis direction of the steel column 2. Since the steel column 2 is often easy to bend toward the weak axis side of the I-beam during an earthquake, the support rod 3 is arranged on the weak axis side of the steel column 2, and the steel column 2 can be supported when the steel column 2 rotates. The support rod 3 is located directly above the cross beam 1, that is, the projection of the support rod 3 on the horizontal plane is located on the cross beam 1. When the steel column 2 tilts toward the side of the support rod 3, the support rod 3 can support the steel column 2. The top end of the support rod 3 is hinged to the upper part of the steel column 2. When the steel column 2 tilts, the support rod 3 can rotate relative to the steel column 2. The middle part of the support rod 3 is hinged with a first connecting rod 3, and the end of the first connecting rod 4 away from the support rod 3 is hinged to the cross beam 1. That is, a four-bar mechanism is formed by the crossbeam 1, the steel column 2, the support rod 3 and the first connecting rod 4, so that when the steel column 2 rotates, the support rod 3 can be driven to rotate by the first connecting rod 4, so that the angle between the support rod 3 and the steel column 2 is increased. When the bottom end of the support rod 3 is against the crossbeam 1, the steel column 2 can be supported to prevent the steel column 2 from collapsing. Increasing the angle between the support rod 3 and the steel column 2 can improve the stability of the support. Specifically, a rotating shaft 5 is fixed on the top of the first connecting rod 4 with an axis horizontally arranged, and a through hole 6 corresponding to the rotating shaft 5 is provided in the middle of the support rod 3. The rotating shaft 5 passes through the through hole 6 and can rotate in the through hole 6. A second connecting rod 7 arranged parallel to the first connecting rod 4 is fixed on the end of the rotating shaft 5 away from the first connecting rod 4. The length of the second connecting rod 7 is equal to that of the first connecting rod 4. The bottom end of the second connecting rod 7 is hinged to the crossbeam 1, and the device can be made more stable through the second connecting rod 7.

[0017] In order to prevent the angle between the support rod 3 and the steel column 2 from being too large, resulting in the support rod 3 being unable to provide support for the steel column 2, a first pull rod 8 is hinged in the middle of the support rod 3, and a second pull rod 9 is hinged at one end of the first pull rod 8 away from the support rod 3. The end of the second pull rod 9 away from the first pull rod 8 is hinged to the lower part of the steel column 2. When the angle between the support rod 3 and the steel column 2 increases, the first pull rod 8 and the second pull rod 9 rotate. When the first pull rod 8 and the second pull rod 9 are collinear, the support rod 3 can be limited from rotating relative to the steel column 2 to prevent the angle from being too large.

[0018] The working principle of the utility model is as follows:

[0019] Since the steel column 2 may bend and collapse to any one of the two weak axis sides during an earthquake, a support rod 3 may be provided on each of the two weak axis sides of the steel column 2. When vibration is generated by an earthquake or other reasons, the steel column 2 tilts and rotates to any one of the support rods 3 under the action of the vibration. When the steel column 2 rotates, the support rod 3 rotates relative to the steel column 2, so that the support rod 3 is unfolded. When the bottom end of the support rod 3 abuts against the crossbeam 1, the steel column 2 can be supported (such as Figure 3 As shown in the figure), the steel column 2 is prevented from further tilting and collapsing, thereby supporting the building and preventing people inside the building from being injured. A safe passage can be formed between the steel column 2 and the support rod 3. The remaining floors slowly tilt while maintaining the overall structure without obvious damage, thereby ensuring the survival rate of people after the earthquake, the speed and safety of rescue.

[0020] For low-rise steel structure buildings, such as factory workshops, the steel column 2 is not set on the crossbeam but directly on the ground. The first connecting rod 4 and the second connecting rod 7 can be hinged to the ground at one end away from the support rod. When the steel column 2 is tilted and rotated, the support rod 3 is unfolded, and when the bottom end of the support rod 3 is against the ground, the support of the steel column 2 can be completed.
