Description

Technical Field

[0001] This application relates to the technical field of construction, and more particularly, to a support device. Background Art

[0002] In the field of building structures, with the continuous progress of construction technology, various large and complex structures are increasing, and the requirements for support structures are also getting higher. In the prior art, the support structure has experienced a development stage from simple to complex and from single function to multi-function. In the early stage, the support structure mainly consisted of simple components such as columns and beams, mainly used to meet the basic load-bearing requirements. With the increase of building span and load, the support structure has been continuously optimized, and more efficient support systems such as trusses and grids have emerged.

[0003] When supporting a large-span truss, the support device, as a common support structure, has been widely used. The support device consists of two inclined columns, shaped like a "V", with advantages such as simple structure and clear force transmission, and can effectively transfer the load of the truss to the foundation. However, there are still certain problems with the existing support devices in terms of anti-overturning. When the large-span truss is subjected to large horizontal loads along its length direction, such as wind loads and seismic loads, the support device may tilt or even collapse due to insufficient anti-overturning ability, thus affecting the safety of the entire building structure.

[0013] In one embodiment, the support portion has a mating groove for connecting the mounting member at one end near the mounting member.

[0014] In one embodiment, the mounting component is a fan-shaped mounting shell, the fan-shaped mounting shell is provided with a reinforcing rib plate, the fan-shaped mounting shell has a horizontal end face for providing a mounting base for the support component and an inclined end face for providing a mounting base for the support leg, the number of the inclined end faces is two, and the two inclined end faces are inclined to each other.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" 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 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 application based on the specific circumstances.

[0040] Embodiments of this application provide support devices, such as... Figures 1 to 4 As shown, the support device includes a herringbone support structure 1000 and a connecting structure 2000, wherein the herringbone support structure 1000 is used to support the truss structure.

[0041] One end of the connecting structure 2000 is connected to the herringbone support structure 1000, and the connection method is, for example, welding or bolt connection.

[0042] The other end of the connecting structure 2000 is provided with a connecting position 2400. For example, the connecting structure 2000 is connected to the external building structure through the connecting position 2400, so that the A-frame support structure 1000 is indirectly connected to the external building structure, thereby further stabilizing the support device.

[0043] For example, the connection structure 2000 is configured to provide a connection between the herringbone support structure 1000 and the external building structure. The connection provided by the connection structure 2000 may be a fixed connection or a movable connection.

[0044] For example, the connecting structure 2000 is configured as a plate structure to provide a fixed connection to the herringbone support structure 1000 and the external building structure, with one end of the plate structure connected to the herringbone support structure 1000 and the other end connected to the external building structure; in another embodiment, the connecting structure 2000 is configured as a hinged joint or a spherical joint to provide a movable connection to the herringbone support structure 1000 and the external building structure. Of course, the connecting structure 2000 can also be configured as other forms of mechanical structure.

[0045] The A-frame support structure 1000 has good support performance and anti-overturning performance on the plane where its two support legs 1200 are located. It can effectively resist the overturning moment in the plane and ensure the stability of the support device under normal stress conditions.

[0046] However, when subjected to a force perpendicular to the plane containing the two supporting legs 1200, the A-frame support structure 1000 is prone to tipping over. The connecting structure 2000 of this application, however, connects to the external building structure via a connecting point 2400, indirectly linking the A-frame support structure 1000 to the building structure. When the A-frame support structure 1000 is subjected to forces in other directions, the connecting structure 2000 can transfer some of the force to the building structure, sharing the force with the help of the building structure's stability. This significantly enhances the A-frame support structure 1000's resistance to tipping in the direction perpendicular to the plane containing the supporting legs 1200, improves the reliability of the entire support device, and enables it to adapt to more complex and variable stress environments.

[0047] like Figure 1 As shown, in one embodiment, the herringbone support structure 1000 includes a support member 1100 that provides support, two support legs 1200 arranged at an angle to each other, and an installation member 1300 that provides an installation base for the support legs 1200 and the support member 1100 and transmits the force of the support member 1100 to the support legs 1200. One end of the connecting structure 2000 is connected to the support member 1100.

[0048] For example, support member 1100 is used to provide support for the truss.

[0049] For example, the support leg 1200 is fixedly mounted on the mounting component 1300 by means of welding, snap-fitting or bolting.

[0050] For example, the support member 1100 is fixedly mounted on the mounting member 1300 by means of welding, snap-fitting or bolt connection.

[0051] For example, one end of the connecting structure 2000 is fixedly mounted on the support member 1100 by means of welding, snap-fitting or bolting.

[0052] For example, such as Figure 8 and Figure 9 As shown, the angle between the support leg 1200 and the vertical direction is α, such as 10°, 12° or 15°.

[0053] For example, such as Figure 8 and Figure 9 As shown, the included angle between the two supporting legs 1200 is β, which can be, for example, 20°, 25° or 30°.

[0054] In this application, the A-frame support structure 1000 comprises a support member 1100, two support legs 1200 arranged at an included angle, and a mounting member 1300. The support member 1100 provides support for the truss, and the mounting member 1300 provides a mounting foundation for the support legs 1200 and the support member 1100, and transmits the truss force borne by the support member 1100 to the support legs 1200. This structure allows the load transmitted from the truss to be rationally distributed to the two support legs 1200 through the support member 1100, and then transmitted to the foundation by the support legs 1200, avoiding excessive local stress, improving the load-bearing capacity of the entire support device, and ensuring stable support of the truss under various working conditions.

[0055] In this application, the two support legs 1200 are set at an angle to each other, forming a stable triangular support system. This structure has good mechanical stability, can effectively resist overturning moment, reduce the risk of tilting or collapsing when the support device is subjected to external force, and improve the reliability and safety of the support device.

[0056] like Figure 2 As shown, in one embodiment, the support member 1100 includes two support portions 1110 and a connecting portion 1120 for connecting the two support portions 1110. The two support portions 1110 are vertically disposed on the mounting member 1300, and there is a gap between the two support portions 1110. The connecting portion 1120 is located in the gap and is fixedly connected to the two support portions 1110.

[0057] For example, the connecting part 1120 is a solid block structure or a hollow connecting shell.

[0058] For example, the support 1110 provides support and mounting foundation for the truss.

[0059] like Figure 3 As shown, a bolt hole 1118 is provided at the end of the support part 1110 away from the mounting part 1300. The bolt hole 1118 facilitates the bolt connection between the support part 1110 and the truss.

[0060] The support part 1110 provides support and a mounting foundation for the truss. A bolt hole 1118 is provided at the end of the support part 1110 furthest from the mounting component 1300, facilitating bolt connection between the support part 1110 and the truss. The bolt connection method is convenient for installation and disassembly, allowing construction workers to quickly and accurately install the truss onto the support part 1110 using bolts, thus improving construction efficiency.

[0061] The structure of the two support parts 1110 helps to reduce stress concentration. Under load, the two support parts 1110 can share the stress, avoiding structural damage caused by excessive local stress. At the same time, the presence of the connecting part 1120 also plays a role in dispersing stress, further improving the durability and service life of the support 1100.

[0062] like Figure 2 and Figure 3 As shown, in one embodiment, the support portion 1110 is a shell 1119 with a cavity. Exemplarily, the shell 1119 of the support portion 1110 is a quadrangular prism structure with a rectangular cross-section along a direction perpendicular to its length. Of course, in other embodiments, the shell 1119 of the support portion 1110 can also be other polygonal prism structures, such as triangular prisms, pentagonal prisms, or hexagonal prisms, etc., which will not be elaborated here.

[0063] like Figure 3 and Figure 6 As shown, the housing 1119 is vertically arranged, that is, the length direction of the housing 1119 is parallel to the vertical direction; a T-shaped stiffening plate 1112 is provided at one end of the housing 1119 near the mounting member 1300, and an inverted T-shaped stiffening plate 1114 is provided at one end of the housing 1119 of the support part 1110 away from the mounting member 1300, so as to increase the strength of the housing 1119 of the support part 1110.

[0064] The support 1110 adopts a hollow shell 1119 structure, which significantly reduces its weight compared to a solid structure while ensuring a certain load-bearing capacity. For example, under the same material usage and load-bearing requirements, the shell 1119 structure can remove excess internal material, reducing the overall mass of the structure. This not only facilitates transportation and installation but also reduces pressure on the foundation and lowers foundation costs.

[0065] A T-shaped stiffening plate 1112 is provided at one end of the shell 1119 near the mounting member 1300, and an inverted T-shaped stiffening plate 1114 is provided at the other end away from the mounting member 1300. These stiffening plates can significantly increase the strength of the support 1110 and the shell 1119. For example, the T-shaped stiffening plate 1112, whose cross-sectional shape is similar to the letter "T", can effectively resist the bending deformation and local buckling of the shell 1119 under load. When the shell 1119 is subjected to pressure perpendicular to its surface, the stiffening plate can distribute the load to a larger area, reduce the stress on the shell 1119 wall panels, and thus improve the overall stability of the shell 1119.

[0066] The stiffening plates optimize the stress distribution inside the shell 1119. Near the mounting member 1300, the T-shaped stiffening plate 1112 can enhance the strength of the connection between the shell 1119 and the mounting member 1300, preventing damage due to stress concentration at the connection. Far from the mounting member 1300, the inverted T-shaped stiffening plate 1114 can balance the load on the upper part of the shell 1119, making the stress distribution of the shell 1119 more uniform in the length direction and improving the overall deformation resistance of the support 1110.

[0067] like Figure 3 and Figure 6 As shown, in one embodiment, the T-shaped stiffening plate 1112 includes a first plate 1112a and a second plate 1112b. The first plate 1112a is vertically arranged and one end is connected to the inner wall of the housing 1119, and the other end is connected to the second plate 1112b. The second plate 1112b is horizontally arranged and both ends are fixedly connected to the inner wall of the housing 1119. The second plate 1112b is a double plate arranged at intervals. One of the double plates of the second plate 1112b is close to and connected to the first plate 1112a, and the double plates are arranged in parallel.

[0068] For example, the first plate 1112a is fixedly mounted on the inner wall of the housing 1119 by means of welding or integral molding.

[0069] For example, the second plate 1112b is fixedly mounted on the inner wall of the housing 1119 by means of welding or integral molding.

[0070] For example, one of the plates of the first plate 1112a and the second plate 1112b is fixedly connected by welding or integral molding.

[0071] The first plate 1112a primarily bears the bending moment generated by the load, effectively transferring the load to other parts of the shell 1119, thereby enhancing the shell 1119's ability to resist bending deformation. For example, when the support 1110 is subjected to a large vertical pressure transmitted from the truss, the first plate 1112a can prevent the shell 1119 from bending excessively in the vertical direction, ensuring the structural stability of the support 1110.

[0072] In this application, the double-plate configuration of the second plate 1112b increases the connection area between the stiffening plate and the inner wall of the shell 1119, improving local compressive strength. When a load is applied to the shell 1119, the second plate 1112b can distribute the load over a larger area, reducing local stress in the shell 1119 wall panels and preventing damage due to stress concentration. For example, near the mounting member 1300, the second plate 1112b can enhance the strength of the connection between the shell 1119 and the mounting member 1300, ensuring that the connection will not loosen or be damaged under load.

[0073] In this application, when the shell 1119 is subjected to a lateral force in the horizontal direction, the double-plate structure of the second plate 1112b can effectively limit the lateral displacement of the shell 1119 wall panels, ensuring the overall shape and stability of the shell 1119. The spaced-apart double-plate structure can increase the horizontal stiffness of the shell 1119, preventing local buckling of the shell 1119 wall panels under pressure. The gap between the double plates can provide a certain deformation space, while the parallel arrangement of the double plates can mutually restrain each other, jointly resisting horizontal deformation.

[0074] like Figure 3 As shown, in one embodiment, the inverted T-shaped stiffening plate 1114 includes a vertical plate 1114a and a horizontal plate 1114b. The vertical plate 1114a is vertically arranged, and the horizontal plate 1114b and the vertical plate 1114a are fixedly connected. The vertical plate 1114a and the first plate 1112a are perpendicular to each other.

[0075] For example, the vertical plate 1114a is fixedly mounted on the inner wall of the housing 1119 by means of welding or integral molding.

[0076] For example, the horizontal plate 1114b is fixedly mounted on the inner wall of the housing 1119 by means of welding or integral molding.

[0077] For example, one of the vertical plate 1114a and the horizontal plate 1114b is fixedly connected by welding or integral molding.

[0078] The vertical plate 1114a of the inverted T-shaped stiffening plate 1114 is vertically arranged. When the shell 1119 is subjected to a load perpendicular to its surface, the vertical plate 1114a bears the shear force and bending moment generated by the load, effectively enhancing the shell 1119's ability to resist bending deformation. At the end of the support 1110 away from the mounting member 1300, when the load transmitted from the truss is large, the vertical plate 1114a can prevent the shell 1119 from bending excessively at this location, ensuring the structural stability of the support 1110.

[0079] In this application, the horizontal plate 1114b is fixedly connected to the vertical plate 1114a, which further increases the overall rigidity of the stiffening plate.

[0080] The vertical plate 1114a and the first plate 1112a are perpendicular to each other, so that the T-shaped stiffening plate 1112 and the inverted T-shaped stiffening plate 1114 form a cooperative support system within the shell 1119, thereby enabling the shell 1119 to resist shear force and bending moment generated by loads at different angles.

[0081] In one embodiment, such as Figure 5 As shown, a bolt groove is provided at one end of the vertical plate 1114a near the bolt hole 1118; when the bolt used to connect the truss and the housing 1119 of the support 1110 passes through the bolt hole 1118, the bolt groove can prevent the vertical plate 1114a from interfering with the bolt.

[0082] like Figure 3 As shown, in one embodiment, the support portion 1110 has a mating groove 1116 for connecting to the mounting member 1300 at one end near the mounting member 1300. Exemplarily, the housing 1119 is a quadrangular prism shell, and the mating groove 1116 is a U-shaped groove.

[0083] like Figure 2 and Figure 3 As shown, the mating groove 1116 increases the connection area between the housing 1119 of the support 1110 and the mounting part 1300, reducing stress concentration, increasing connection strength, and improving reliability. Because the mating groove 1116 increases the connection area and optimizes stress distribution, it reduces stress concentration and stress amplitude variations at the connection point. During long-term use, mechanical structures are repeatedly subjected to alternating loads; stress concentration and stress amplitude variations are the main causes of fatigue failure. By setting the mating groove 1116, the risk of fatigue damage at the connection point is reduced, the fatigue resistance of the connection between the support 1110 and the mounting part 1300 is improved, and the service life of the mechanical structure is extended.

[0084] like Figure 7 and Figure 8As shown, in one embodiment, the mounting component 1300 is a fan-shaped mounting shell, and a reinforcing rib plate 1310 is provided inside the fan-shaped mounting shell.

[0085] The fan-shaped mounting housing has a horizontal end face 1320 for providing a mounting base for the support member 1100 and an inclined end face 1330 for providing a mounting base for the support leg 1200. There are two inclined end faces 1330, which are inclined between each other.

[0086] For example, one support leg 1200 is disposed on one inclined end face 1330, and another support leg 1200 is disposed on another inclined end face 1330.

[0087] For example, the support leg 1200 and the inclined end face 1330 are connected by welding, snap-fitting or bolting.

[0088] like Figure 3 and Figure 4 As shown, in one embodiment, the connection structure 2000 includes a fixing plate 2100, a hinge plate 2200, and a connecting frame 2300.

[0089] The fixing plate 2100 is fixedly connected between the two support parts 1110, and the fixing method is, for example, welding or bolt connection.

[0090] One end of the hinge plate 2200 is hinged to the fixed plate 2100, and the other end of the hinge plate 2200 is fixedly connected to the connecting frame 2300, for example, by welding or bolt connection.

[0091] The connection position 2400 is located on the connector 2300.

[0092] The connecting frame 2300 is an H-shaped frame structure. For example, the connecting frame 2300 connects to the reinforced concrete structure of the external building structure.

[0093] In this application, the hinge plate 2200 is hinged to the fixed plate 2100, allowing the hinge plate 2200 and the fixed plate 2100 to rotate freely within a certain range, which can effectively release the load and reduce the stress concentration inside the connection structure 2000.

[0094] For example, the hinge plate 2200 is connected to the fixed plate 2100 by a pin to achieve the hinge connection between the two. The pin installation is relatively simple, without the need for complex welding or high-precision bolt pre-tightening, and the construction speed is fast, making it suitable for on-site high-altitude operations.

[0095] like Figure 3 or Figure 6As shown, in one embodiment, the fixing plate 2100 is a double plate spaced apart and at the same horizontal height as the second plate 1112b, which can ensure that when the fixing plate 2100 is subjected to a lateral force, the second plate 1112b can resist the lateral force transmitted by the fixing plate 2100, thereby improving the lateral stiffness of the structure.

[0096] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0097] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
