Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and in particular to a node structure and a method for determining a balance point. Background Art

[0002] In the design of super high-rise office buildings, glass curtain walls are warmly welcomed by the market for their gorgeous and grand appearance, and have become an important decorative feature of modern high-rise buildings. In the continuous innovation of architecture, especially in the aerial platform of the corporate headquarters building, the use of light, thin and transparent glass curtain walls can become the highlight of the building. In order to achieve the light and transparent effect, cable curtain walls are mostly used. For the existing super-large span single-layer cable curtain walls, the usual practice is that the glass curtain wall adopts a single-layer cable system, in which the single-layer cable needs to be pre-tensioned, and the tension of the single-layer cable needs to be borne by the core tube, and finally achieve force balance. From a plane point of view, if Figure 1 As shown, multiple frame columns 30 (two are shown in the figure) are arranged near the curtain wall 20. A single-layer cable 40 is arranged between the two frame columns 30, and the frame column 30 is connected to the cylinder 10 of the core tube through multiple cross beams 50. In order to ensure that the pre-tension of the single-layer cable 40 can be smoothly transmitted to the cylinder 10, the single-layer cable 40 is usually located in the middle of the frame column. At this time, the distance between the single-layer cable 40 and the curtain wall 20 is relatively far, resulting in an unsightly curtain wall 20. Changing the connection position of the single-layer cable 40 and the frame column 30 will cause the single-layer cable 40 to generate a large torque on the frame column 30, resulting in instability of the frame column 30, and even a risk of tipping.

[0003] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a node structure to solve the problems in the prior art that the cables are far away from the curtain wall, resulting in an unsightly curtain wall and the cables generate a large torque on the columns, making the columns unstable.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0006] A node structure, the node structure includes a square column arranged near a glass curtain wall, the node structure also includes a first connecting beam and a second connecting beam connected to the square column, and a cable is connected to the front end surface of the square column, the cable is parallel to the front end surface of the square column, and the cable intersects with an extension line of the first connecting beam and an extension line of the second connecting beam at one point. The node structure, wherein a connecting block is arranged on the front end surface of the square column, and the cable is connected to the connecting block.

[0007] The node structure, wherein the distances between the connection block and the two side edges of the front end surface are equal.

[0008] The node structure, wherein the first connecting beam is connected to the left end surface of the square column, and the second connecting beam is connected to the right end surface of the square column.

[0009] The node structure, wherein the first connecting beam, the second connecting beam and the cable are not colinear with each other.

[0010] The node structure, wherein the first connecting beam, the second connecting beam and the cable are coplanar.

[0011] The node structure, wherein the first connecting beam, the second connecting beam and the cable are in the same horizontal plane perpendicular to the square column.

[0012] A method for determining a balance point, the method comprising:

[0013] A cable is arranged on the front end surface of the square column, and the cable is parallel to the front end surface of the square column;

[0014] A first connecting beam is arranged on the square column, and an extension line of the first connecting beam intersects with the cable at a first intersection point;

[0015] A second connecting beam is arranged on the square column, and the second connecting beam intersects with the cable at a second intersection;

[0016] Determine whether the first intersection point coincides with the second intersection point. If so, set the first intersection point or the second intersection point as a balance point. If not, adjust the position of the second connecting beam until the second intersection point coincides with the first intersection point.

[0017] Beneficial effect: The square column in the present invention is connected with the first connecting beam and the second connecting beam, and a cable is connected to the front end surface of the square column, and the cable is parallel to the front end surface of the square column. Since the front end surface of the square column is close to the glass curtain wall, the cable is close to the glass curtain wall, thereby ensuring the aesthetics of the glass curtain wall. At the same time, by making the cable intersect with the extension line of the first connecting beam and the extension line of the second connecting beam at one point, it is avoided that the cable generates a large torque on the square column, thereby improving the stability of the square column.

[0026] The invention is further described below by describing embodiments in conjunction with the accompanying drawings.

[0027] This embodiment provides a node structure, such as Figure 2As shown in FIG. 4 , the node structure includes a square column 1, a first connecting beam 2 and a second connecting beam 3. One end of the first connecting beam 2 is connected to the square column 1, and the other end is connected to the core tube 7. One end of the second connecting beam 3 is connected to the square column 1, and the other end is connected to the core tube 7. The square column 1 is a vertical column with a square cross section. A cable 4 is connected to the front end face of the square column 1, and the cable 4 is parallel to the front end face of the square column 1. The front end face of the square column 1 is close to the glass curtain wall 6, so that the cable is close to the glass curtain wall 6 and is close to the glass curtain wall 6, thereby not affecting the aesthetics of the glass curtain wall 6; the cable 4 is arranged horizontally, that is, when the cable 4 exerts a force on the square column 1, the tension is also in a horizontal direction and parallel to the front end face of the square column 1; the cable 4 intersects with the extension line of the first connecting beam 2 and the extension line of the second connecting beam 3 at one point, so that when the cable 4, the first connecting beam 2 and the second connecting beam 3 all exert a force on the square column 1, the three forces converge at one point, thereby not generating additional torque on the square column 1 to cause instability of the square column 1 or even tipping over of the square column 1.

[0028] In a specific embodiment, two node structures are arranged between the glass curtain wall 6 and the core tube 7, that is, two square columns 1 are arranged between the glass curtain wall 6 and the core tube 7, one end of the cable 4 is connected to the front end face of one of the square columns 1, and the other end is connected to the front end face of the other square column 1, and the cable 4 is parallel to the glass curtain wall 6, and the cable 4 is connected to the glass curtain wall 6 by a plurality of connectors to reinforce the glass curtain wall 6, for example, the connector is a claw.

[0029] In the present invention, the square column 1 is connected with the first connecting beam 2 and the second connecting beam 3, and the front end surface of the square column 1 is connected with a cable 4, and the cable 4 is parallel to the front end surface of the square column 1. Since the front end surface of the square column 1 is close to the glass curtain wall 6, the cable is close to the glass curtain wall 6, thereby ensuring the aesthetics of the glass curtain wall 6. At the same time, by making the cable 4 intersect with the extension line of the first connecting beam 2 and the extension line of the second connecting beam 3 at one point, it is avoided that the cable 4 generates a large torque on the square column 1, thereby improving the stability of the square column 1.

[0030] A connection block 5 is provided on the front end face of the square column 1, and the connection block 5 is fixedly connected to the front end face of the square column 1. For example, the square column 1 is a steel column, and the connection block 5 is also a steel connection block 5. The connection block 5 is welded to the square column 1. Of course, the square column 1 and the connection block 5 can also be fixedly connected by screws, but the present invention is not limited to this. Since the cable 4 is parallel to the front end face of the square column 1, when the cable 4 exerts a tensile force on the square column 1, the direction of the tensile force is also along the front end face of the square column 1. If the intersection of the first connecting beam 2 and the second connecting beam 3 is located on the square column 1, and the tensile force direction of the cable 4 is parallel to the front end face of the square column 1 and is not on the square column 1, at this time, the cable 4 exerts a torque on the square column 1. When the tensile force of the cable 4 is greater, the torque is greater, thereby making the instability of the square column 1 higher.

[0031] The distance between the connecting block 5 and the two side edges of the front end face is equal, that is, the connecting block 5 is located in the middle position of the width direction of the front end face; the intersection of the first connecting beam 2, the second connecting beam 3 and the cable 4 can be located at the connection between the cable 4 and the connecting block 5, or at the connection between the cable 4 and the connecting block 5, that is, as long as the three forces converge at one point, the square column 1 will not be unstable due to the generation of torque.

[0032] In a specific implementation of the embodiment 1, the end of the first connecting beam 2 not connected to the core tube is connected to the left end face of the square column 1, the end of the second connecting beam 3 not connected to the core tube is connected to the right end face of the square column 1, and the extension line of the first connecting beam 2, the extension line of the second connecting beam 3 and the cable 4 intersect at one point, and the intersection is located at the connection between the cable 4 and the connecting block 5. The first connecting beam 2 and the second connecting beam 3 are not colinear with the cable 4.

[0033] In another specific implementation of the present embodiment, the end of the first connecting beam 2 not connected to the core tube is connected to the rear end face of the square column 1, the end of the second connecting beam 3 not connected to the core tube is connected to the right end face of the square column 1, and the extension line of the first connecting beam 2, the extension line of the second connecting beam 3 and the cable 4 intersect at one point, and the intersection is located at the connection between the cable 4 and the connecting block 5.

[0034] Of course, the first connecting beam 2 can also be connected to the right end face of the square column 1, and the second connecting beam 3 can be connected to the left end face of the square column 1. The present invention is not limited to this. Since the core tube is located on the side of the square column 1 away from the cable 4, the first connecting beam 2 and the second connecting beam 3 can only be connected to the left end face, right end face or rear end face of the square column 1, but cannot be connected to the front end face of the square column 1.

[0035] Furthermore, the first connecting beam 2, the second connecting beam 3 and the cable 4 are coplanar. When the first connecting beam 2, the second connecting beam 3 and the cable 4 all generate interaction forces with the square column 1, since each force is along its own length direction, the three forces are also in the same plane, and the three forces meet at a point. Since the three forces meeting at a point in the same plane can achieve force balance, the stability of the square column 1 is further increased. In a specific embodiment, the first connecting beam 2, the second connecting beam 3 and the cable 4 are perpendicular to the square column 1, and the first connecting beam 2, the second connecting beam 3 and the cable 4 are coplanar, that is, the first connecting beam 2, the second connecting beam 3 and the cable 4 are in the same horizontal plane. Of course, the first connecting beam 2 and the second connecting beam 3 may not be perpendicular to the square column 1, but may be inclined relative to the square column 1, and the present invention is not limited to this.

[0036] Furthermore, the cross-sections of the first connecting beam 2 and the second connecting beam 3 are both square, and the side lengths of the cross-sections of the first connecting beam 2 and the second connecting beam 3 are both smaller than the side lengths of the cross-section of the square column 1, thereby facilitating the connection between the first connecting beam 2 and the second connecting beam 3 and the surface of the square column 1.

[0037] The present invention also provides a method for determining a balance point, characterized in that the method comprises:

[0038] A cable is arranged on the front end surface of the square column, and the cable is parallel to the front end surface of the square column;

[0039] A first connecting beam is arranged on the square column, and an extension line of the first connecting beam intersects with the cable at a first intersection point;

[0040] A second connecting beam is arranged on the square column, and the second connecting beam intersects with the cable at a second intersection;

[0041] Determine whether the first intersection point coincides with the second intersection point. If so, set the first intersection point or the second intersection point as a balance point. If not, adjust the position of the second connecting beam until the second intersection point coincides with the first intersection point.

[0042] In summary, the present invention discloses a node structure and a method for determining a balance point, wherein the node structure includes a square column arranged near a glass curtain wall, the node structure also includes a first connecting beam and a second connecting beam connected to the square column, and a cable is connected to the front end face of the square column, the cable is parallel to the front end face of the square column, and the cable intersects at one point with an extension line of the first connecting beam and an extension line of the second connecting beam. In the present invention, the square column is connected with the first connecting beam and the second connecting beam, and a cable is connected to the front end face of the square column, and the cable is parallel to the front end face of the square column. Since the front end face of the square column is close to the glass curtain wall, the cable is close to the glass curtain wall, thereby ensuring the aesthetics of the glass curtain wall. At the same time, by making the cable intersect at one point with the extension line of the first connecting beam and the extension line of the second connecting beam, it is avoided that the cable generates a large torque on the square column, thereby improving the stability of the square column.
