Description

Technical Field

[0001] The invention belongs to the field related to support equipment, and specifically relates to an out-of-plane freely deformable wind-resistant support. Background Art

[0002] For flexible buildings such as steel structures, wind loads are design loads and sometimes even play a decisive role in structural design. At present, the wind resistance measures for high-rise buildings are mainly to resist the effects of wind loads by enhancing the wind resistance of the structure itself, that is, by improving the strength and stiffness of the structure itself, and by storing and consuming wind shock energy to resist wind loads, such as arranging ordinary steel supports inside the structure. However, the existing arrangement of steel supports will have an adverse effect on the use of indoor space, causing difficulties in the use of the structure, and because the steel structure components are constrained at both ends and have no room for expansion, they have poor adaptability to environmental factors such as temperature changes. Stress concentration may occur under the alternating action of temperature stress, affecting the use of components. Summary of the invention

[0003] The object of the present invention is to provide an out-of-plane freely deformable wind-resistant support to solve the problem of poor adaptability of existing ordinary steel supports to indoor space occupation and to environments such as temperature changes, as mentioned in the above background technology.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A wind-resistant support that can be deformed freely out of a plane includes an end node, a diagonal support and a central wind-resistant node. One end of the diagonal support is connected to the end node, and the other end is connected to the central wind-resistant node. The end node steel plate in the end node is embedded and installed in the main body of the building. All the end nodes form a support surface, and the central wind-resistant node is located outside the support surface.

[0006] A further technical solution is that the end node includes an end node steel plate and two end node flange plates, the two end node flange plates are respectively connected to two side edges of the end node steel plate, and the end node flange plate is perpendicular to the end node steel plate.

[0007] A further technical solution is that the end node steel plate is a polygonal steel plate.

[0008] A further technical solution is that the central wind-resistant node includes a wind-resistant steel plate, vertical stiffening ribs, horizontal stiffening ribs and a wind-resistant node flange plate, and the side edges of the vertical stiffening ribs and the side edges of the horizontal stiffening ribs are both vertically connected to the surface of the wind-resistant steel plate.

[0009] A further technical solution is that the diagonal brace includes a diagonal brace web and two diagonal brace flange plates vertically connected to the diagonal brace web. The diagonal brace includes a diagonal brace web and two diagonal brace flange plates, the two diagonal brace flange plates are respectively connected to the two side edges of the diagonal brace web, and the diagonal brace flange plates are perpendicular to the diagonal brace web.

[0010] A further technical solution is that the thickness of the end node steel plate is consistent with that of the diagonal brace web plate, and the width of the end node flange plate is consistent with that of the diagonal brace flange plate.

[0011] A further technical solution is that it also includes a connecting plate, which includes a connecting plate web and a connecting plate flange plate, the front end of the connecting plate web is connected to the rear end of the diagonal brace web, and the rear end of the connecting plate web is connected to the wind-resistant steel plate; the front end of the connecting plate flange plate is connected to the rear end of the diagonal brace flange plate, and the rear end of the connecting plate flange plate is connected to the wind-resistant node flange plate.

[0012] A further technical solution is that the thickness of the connecting plate web, the diagonal brace web and the end node steel plate are consistent; the width of the connecting plate flange plate, the diagonal brace flange plate and the end node flange plate are consistent.

[0013] A further technical solution is that it also includes a horizontal plate, a side surface of the horizontal plate is connected to the connecting plate, and one end of the horizontal plate is connected to the central wind-resistant node.

[0014] A further technical solution is that the support surface formed by the diagonal brace and the end node has an angle α, and the angle α is any angle between 5° and 20°.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention sets the central wind-resistant node outside the plane where all the end node steel plates are located, that is, the central wind-resistant node is located outside the plane of the building structure, and the end node steel plates are embedded and connected with the main structure of the building. The additional internal force generated by the temperature effect can be released, and the function of free deformation outside the supporting plane can be realized, thereby enhancing its ability to adapt to temperature changes and improving practicality.

DETAILED DESCRIPTION

[0026] In order to better understand the purpose, structure, features and effects of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that the features shown in the drawings are not necessarily drawn to scale. In addition, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right", "front", "back" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. In addition, in the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0028] like Figure 1-6 As shown, a wind-resistant support that can be deformed freely out of the plane includes an end node 1, a diagonal brace 2 and a central wind-resistant node 4. One end of the diagonal brace 2 is connected to the end node 1, and the other end of the diagonal brace 2 is connected to the central wind-resistant node 4. The overall shape of the support is similar to an "X" shape. The end node 1 includes an end node steel plate 101, which is embedded in the main structure of the building. All end node steel plates 101 form a support surface, and the central wind-resistant node 4 is located outside the support surface, so that the central wind-resistant node 4 in the middle of the support is outside the plane where the main structure of the building is located. Under the action of temperature, the end node steel plate 101 in the end node 1 produces bending deformation, and the wind-resistant steel plate 401 in the central wind-resistant node 4 produces an out-of-plane offset, realizing the function of free deformation out of the support plane, releasing the temperature stress inside the main body of the building, thereby enhancing its ability to adapt to temperature changes and improving practicality. At the same time, the support as a whole is outside the plane of the main structure of the building, avoiding occupying indoor use space and affecting the curtain wall, and improving space utilization.

[0029] The end node 1 in the out-of-plane freely deformable wind-resistant support of the present invention comprises an end node steel plate 101 and two end node flange plates 102, the two end node flange plates 102 are respectively connected to the two side edges of the end node steel plate 101, and the end node flange plates 102 are perpendicular to the end node steel plate 101. The end node steel plate 101 is embedded in the main structure of the building and fixed to the main body of the building. The end node flange plates 102 perpendicular to the end node steel plate 101 are respectively connected to the two side surfaces of the end node steel plate 101 to ensure the overall stiffness of the end node and prevent the end node steel plate 101 from being subjected to excessive bending moment when subjected to temperature stress to produce plastic deformation, thereby causing failure of the support function; at the same time, the end of the end node flange plate 102 is connected to the main body of the building to fix the overall stability of the support.

[0030] The end node steel plate 101 in the out-of-plane freely deformable wind-resistant support of the present invention is a polygonal steel plate, which is fixedly connected to the main structure of the building. Under the action of temperature, the polygonal steel plate responds more accurately to the internal force inside the structure, produces out-of-plane bending deformation, thereby driving the support as a whole to produce out-of-plane deviation to release temperature stress and avoid adverse effects of temperature on the structure. The polygonal steel plate can be a thin polygonal steel plate, which is convenient for bending and deformation when subjected to internal force.

[0031] In an out-of-plane freely deformable wind-resistant support of the present invention, the central wind-resistant node 4 includes a wind-resistant steel plate 401, a vertical stiffening rib 403, a horizontal stiffening rib 404 and a wind-resistant node flange plate 402, and the sides of the vertical stiffening rib 403 and the sides of the horizontal stiffening rib 404 are vertically connected to the surface of the wind-resistant steel plate 401, wherein the vertical stiffening rib 403 is in the vertical direction and the horizontal stiffening rib 404 is in the horizontal direction. Vertical stiffening ribs 403 and horizontal stiffening ribs 404 are provided on the front and back of the wind-resistant steel plate 401. The wind-resistant steel plate 401 itself has a certain rigidity. Combined with the vertical stiffening ribs 403 and the horizontal stiffening ribs 404, when the wind load acts on the building, the building structure produces lateral displacement. The wind-resistant steel plate 401 and the stiffening ribs can provide sufficient lateral rigidity for the building structure and reduce the structural displacement under the action of the wind load. At the same time, vertical and horizontal stiffening ribs are set to ensure the overall stability of the support and avoid instability of the wind-resistant steel plate under load.

[0032] The diagonal brace 2 in the out-of-plane freely deformable wind-resistant brace of the present invention comprises a diagonal brace web 201 and a diagonal brace flange plate 202 vertically connected thereto, the front end of the diagonal brace web 201 is connected to the end node steel plate 101, and the front end of the diagonal brace flange plate 202 is connected to the end node flange plate 102. The diagonal brace 2 is a wide flange I-beam as a whole, and the wide flange I-beam diagonal brace has good out-of-plane stiffness and structural stability, lateral stiffness and bending resistance, can balance stress, and ensure the realization of the support function; at the same time, compared with general steel, the I-beam has low cost, high precision, and small residual stress.

[0033] A wind-resistant support that can be freely deformed out of the plane of the present invention also includes a connecting plate 3, which includes a connecting plate web 301 and a connecting plate flange plate 302. The front end of the connecting plate web 301 is connected to the rear end of the diagonal brace web 201, and the rear end of the connecting plate web 301 is connected to the wind-resistant steel plate 401; the front end of the connecting plate flange plate 302 is connected to the rear end of the diagonal brace flange plate 202, and the rear end of the connecting plate flange plate 302 is connected to the wind-resistant node flange plate 402, that is, the front end of the connecting plate 3 is connected to the diagonal brace 2, and the rear end is connected to the central wind-resistant node 4, so that temperature stress, wind load and other forces can be transmitted from the diagonal brace 2 to the central wind-resistant node 4 with a certain stiffness, so as to realize wind resistance and out-of-plane free deformation functions.

[0034] In the out-of-plane freely deformable wind-resistant brace of the present invention, the thickness of the connecting plate web 301, the diagonal brace web 201 and the end node steel plate 101 are consistent; the width of the connecting plate flange plate 302, the diagonal brace flange plate 202 and the end node flange plate 102 are consistent. The thickness of all webs and end node steel plates is consistent, and the width of all flanges is consistent, which facilitates the construction of steel structure welding and ensures the overall beauty of the support.

[0035] The out-of-plane freely deformable wind-resistant support of the present invention further includes a horizontal plate 5, the sides of which are respectively connected to the connecting plate flange plate 302 and the connecting plate web plate 301, and one end of the horizontal plate 5 is connected to the central wind-resistant node 4. The connecting plate flange plate on the left and the connecting plate flange plate on the right are respectively divided into two parts by the horizontal plate 5, so as to simplify the structure of the connecting plate flange plate 302, reduce the production difficulty of the connecting plate flange plate 302, and reduce the production cost; at the same time, the overall support structure is strengthened.

[0036] In the out-of-plane freely deformable wind-resistant brace of the present invention, the support surface formed by the diagonal brace 2 and the end node 1 has an angle α, and the angle α is any angle between 5° and 20°, and the angle α can be 10°.

Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
