Description

Technical Field

[0001] This utility model relates to the field of cantilever beam technology, and in particular to a cantilever beam support structure. Background Technology

[0002] With the continuous development of building technology, cantilever structures have become one of the conventional building structures. One end of the cantilever beam is buried or cast in the support, and the other end extends out of the support.

[0003] In actual construction, especially for large cantilever steel structure platforms, cantilever beams on ordinary slabs require more steel. The overall load of the cantilever steel structure is large, and the shear force of the walls, beams, and slabs is too large, which leads to a decrease in the stability of the cantilever platform. In order to ensure the stability and safety of the building structure, the erection length of the cantilever platform can only be shortened in some construction projects, which cannot meet the large span construction requirements of large cantilever steel structure platforms.

[0004] First, the long length, heavy weight, and large number of cantilever beams increase the complexity and risk of construction. Second, the high altitude and the significant impact of horizontal wind loads place higher demands on the stability and safety of the cantilever beams. Furthermore, the welding and fixing processes are challenging, requiring specialized techniques and strict construction standards to ensure quality. All these difficulties increase the construction difficulty and cost of cantilever beams in building projects. Utility Model Content

[0005] In view of this, the embodiments of this utility model provide a cantilever beam support structure, which solves the technical problem in the prior art that the cantilever beam has a large overall load due to the large amount of steel used in large spans.

[0006] An embodiment of this utility model provides a cantilever beam support structure, comprising:

[0007] An inclined column is set on one side of the supporting surface and gradually moves away from the supporting surface from bottom to top;

[0008] Multiple crossbeams are provided, each of which is spaced apart from bottom to top between the inclined column and the supporting surface. The uppermost crossbeam is provided with multiple reinforcing structures between it and its adjacent crossbeams.

[0009] A vertical support structure, which is also perpendicularly connected to each of the aforementioned beams;

[0010] A cantilevered steel beam is horizontally connected to the uppermost crossbeam and extends to the inclined column on the side away from the crossbeam. The end of the inclined column is connected to the cantilevered steel beam and the uppermost crossbeam by a reinforcing node. The reinforcing node includes column stirrups and column stirrup lap plates. The column stirrups are located inside the inclined column and connected to the crossbeam. The column stirrup lap plates are connected to the cantilevered steel beam. The column stirrups and the column stirrup lap plates are connected and integrated by a poured concrete layer.

[0011] Furthermore, the reinforcing node also includes a stiffening plate and a fastener, the stiffening plate being connected between the inclined column and each of the crossbeams, and the fastener being used to connect multiple crossbeams and the inclined column.

[0012] Furthermore, the fastener is a high-strength bolt, which is arranged in N layers to form a rigid connection between the inclined column and the multiple crossbeams.

[0013] Furthermore, each of the reinforcing structures includes a first diagonal brace and a second diagonal brace, which are connected to the crossbeam to form a triangular structure via embedded parts.

[0014] Furthermore, the embedded component includes an anchor plate and at least three anchor bars, each of which is connected to the anchor plate and is embedded in the crossbeam.

[0015] Furthermore, at least one of the anchor bars is arranged in the opposite direction to the remaining anchor bars.

[0016] Furthermore, the vertical support structure includes edge columns and inner span columns, the edge columns and the inner span columns are arranged in parallel, and the bottom end of the edge column is connected to the inclined column.

[0017] Furthermore, the crossbeam includes a single-layer cantilever beam, a single-layer inner span beam, a second-layer cantilever beam, a second-layer inner span beam, a third-layer cantilever beam, and a third-layer inner span beam.

[0018] Furthermore, concrete beams are provided between the multiple beams and the supporting surfaces.

[0019] Furthermore, the inclination angle of the inclined column is no greater than 15°.

[0020] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The cantilever beam support structure of this utility model cleverly utilizes the special characteristic of the large-angle extension of the inclined columns by setting them up. Through the design of internal steel beams, four inclined braces, and related node reinforcement, it forms a complete structural system with complete stress. While ensuring its safety, it can significantly increase the cantilever span of the cantilever beam, thereby increasing the room functionality and architectural aesthetics in the existing building industry.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings. The following description presents a preferred embodiment of several possible embodiments of this utility model, intended to provide a basic understanding of the utility model, but not intended to identify the key or decisive elements of the utility model or to limit the scope of protection sought.

[0027] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures. Also, it should be understood that, for ease of description, the dimensions of the various parts shown in the figures are not drawn to actual scale.

[0030] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Please refer to Figures 1 to 4 The embodiments of this utility model provide, as follows: Figure 1 As shown, the cantilever beam support structure of this utility model includes three layers of crossbeams of different lengths. Each crossbeam is connected to the support surface 16, and the end of the crossbeam connected to the support surface 16 is vertically flush.

[0032] In this embodiment, multiple crossbeams are simultaneously connected to the inclined column 1 at an angle. The inclined column 1 is an inclined column with an angle not exceeding 15°. The end of the crossbeam away from the support surface 16 is connected to the inclined column 1.

[0033] The crossbeams serve as the main load-bearing structural layers. The uppermost crossbeam is connected to its adjacent crossbeams by multiple reinforcing structures to enhance the stability and load-bearing capacity of the structure, enabling it to be connected over long spans.

[0034] Specifically, before the inclined column 1 is cast, it is equipped with stiffening ribs 15 inside, and the crossbeams are rigidly connected to the inclined column 1 by welding with the stiffening ribs 15.

[0035] Example 1: In order to support the horizontal beam, the vertical support structure is also connected vertically to the horizontal beam, which further improves the integrity of the structure and its resistance to lateral displacement. The cantilever steel beam 13 is connected to the connection point of the uppermost horizontal beam and the inclined column 1, so that the horizontal beam extends outward horizontally to facilitate the connection of large-span cantilever beams.

[0036] It is understandable that a reinforcing node 14 is provided at the connection point. The reinforcing node 14 includes column stirrups 141 and column stirrup lap plates 142. The column stirrups 141 are set inside the inclined column 1. The cantilever steel beam 13 is connected to the inclined column 1 through the column stirrup lap plates 142, which ensures the firmness and reliability of the connection.

[0037] To elaborate further, the column stirrup 141 connects the column stirrup lap plate 142 and the stiffening rib 15, thereby completing the connection between the stiffening rib 15 and the cantilever steel beam 13 and strengthening the connection area.

[0038] The column stirrups 141 are two opposing in-cast components. They are fixed to the steel bars inside the inclined column 1 and rigidly connected after welding. They can be formed by pouring concrete outside the inclined column 1, so that the cantilever steel beam 13 and the inclined column 1 can be effectively strengthened and supported, and form an overall structure to distribute the stress and improve the load-bearing capacity.

[0039] like Figure 2 As shown, the reinforcing node 14 also includes a stiffening plate 143 and a fastener. The stiffening plate 143 is connected between the inclined column 1 and the crossbeam, and the fastener is used to connect the crossbeam and the inclined column 1.

[0040] like Figure 1 As shown, the vertical support structure includes edge column 2 and inner span column 3. The edge column 2 and inner span column 3 are arranged in parallel, and the bottom end of the edge column 2 is connected to the inclined column 1. Together they bear the vertical load and lateral load of the structure, which improves the stability and load-bearing capacity of the structure.

[0041] It should be noted that the crossbeams include a first-layer cantilever beam 4, a first-layer inner span beam 5, a second-layer cantilever beam 6, a second-layer inner span beam 7, a third-layer cantilever beam 8, and a third-layer inner span beam 9. Concrete beams 17 are provided between the crossbeams and the supporting surface 16. The concrete beams 17 and the inclined columns 1 work together to enhance the integrity of the structure and its resistance to lateral displacement.

[0042] Furthermore, the first-floor inner span beam 5 connects the edge column 2 and the inner span column 3; the second-floor inner span beam 7 connects the edge column 2 and the inner span column 3; the third-floor inner span beam 9 connects the edge column 2 and the inner span column 3; the first-floor cantilever beam 4 connects the edge column 2 and the inclined column 1; the second-floor cantilever beam 6 connects the edge column 2 and the inclined column 1; and the third-floor cantilever beam 8 connects the edge column 2 and the inclined column 1.

[0043] It should be noted that the aforementioned inclined column 1, edge column 2, inner span column 3, crossbeam and cantilever steel beam 13 are all made of steel-concrete composite.

[0044] Example 2: The vertical support structure is vertically connected to the horizontal beam, which further improves the overall stability and resistance to lateral displacement of the structure. The cantilever steel beam 13 is connected at the connection point between the uppermost horizontal beam and the inclined column 1, so that the horizontal beam can extend horizontally outward, which facilitates the connection of subsequent large-span cantilever beams.

[0045] At this connection point, a reinforcing node 14 is provided, which includes column stirrups 141 and column stirrup lap plates 142. The column stirrups 141 are set inside the inclined column 1, and the cantilever steel beam 13 is connected to the inclined column 1 through the column stirrup lap plates 142, ensuring the firmness and reliability of the connection.

[0046] In addition, the column stirrups 141 also connect the column stirrup lap plate 142 and the stiffening rib 15, thereby realizing the connection between the stiffening rib 15 and the cantilever steel beam 13 and further strengthening the connection. The column stirrups 141 are two opposing cast-in-place components. They are fixed to the steel bars in the inclined column 1 and thus built into the interior of the inclined column 1. A rigid connection is achieved by welding. Then, concrete is poured on the outside of the inclined column 1 to form a solid structure. This effectively strengthens the support between the cantilever steel beam 13 and the inclined column 1 and forms an integral structure to distribute the stress and improve the load-bearing capacity of the structure.

[0047] The reinforced node 14 also includes stiffening plates 143 and fasteners. The fasteners are high-strength bolts 144. The high-strength bolts 144 are arranged in N layers to form a rigid connection between the inclined column 1 and the beam, which enhances the integrity and shear resistance of the structure.

[0048] like Figure 1 As shown, each reinforcing structure includes a first diagonal brace 11 and a second diagonal brace 12. The first diagonal brace 11 and the second diagonal brace 12 are connected to the crossbeam through the embedded part 10 to form a triangular structure, which improves the stability and resistance to lateral displacement of the structure.

[0049] Please see Figure 4 The embedded part 10 includes an anchor plate 101 and at least three anchor bars 102. Each anchor bar 102 is connected to the anchor plate 101. The anchor bars 102 are embedded in the crossbeam to ensure a firm connection between the embedded part 10 and the crossbeam.

[0050] In order to improve the shear resistance of the embedded part 10 in different directions, at least one anchor bar 102 is set in the opposite direction to the other anchor bars 102, which further enhances the anchoring effect of the embedded part 10.

[0051] In the actual construction process, the positions and dimensions of each beam, inclined column 1, vertical support structure, and reinforcing structure are first determined according to the design requirements. Then, the foundation construction is carried out to ensure the flatness and load-bearing capacity of the support surface 16. Next, each beam is installed, and the reinforcing structure is connected to the beam to form a triangular structure through the embedded parts 10. Then, the inclined column 1 and vertical support structure are installed to ensure that the inclination angle of the inclined column 1 is not greater than 15° to meet the stability and load-bearing capacity requirements of the structure. Finally, the cantilever steel beam 13 is installed, and a reinforcing node 14 is set at the connection point. The cantilever steel beam 13 is firmly connected to the inclined column 1 through the column stirrups 141 and the column stirrup lap plate 142. During the construction process, the operation is strictly carried out in accordance with the design requirements to ensure the installation accuracy and connection quality of each component, so as to guarantee the safety and reliability of the structure.

It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.
