Description

Technical Field

[0001] This invention relates to the field of building structure technology, and in particular to a transfer truss. Background Technology

[0002] With the continuous increase in building height, high-rise and super high-rise buildings are emerging in large numbers, and the use of steel structures is gradually increasing. Since steel columns cannot be installed in the lobby of super high-rise buildings, and large-span beams in super high-rise buildings cannot meet the load-bearing requirements, a transfer floor is often added above the lobby to facilitate the installation of steel columns and reduce the local span for easier construction. Transfer trusses are commonly used in such applications. However, because the transfer truss is located on a lower floor but bears the load generated by a building tens or hundreds of meters high, the load-bearing capacity of the truss itself is crucial. Therefore, how to optimize the distribution of the force transmission path of the transfer truss to reasonably distribute the stress and improve the load-bearing capacity is an urgent problem to be solved. Summary of the Invention

[0003] The purpose of this invention is to provide a conversion truss that has an effective force transmission path, can reasonably distribute the force, and achieve the effect of improving the overall load-bearing capacity.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] The conversion truss includes:

[0006] The truss main body is located between two adjacent steel pipe columns and includes an upper truss main body and a lower truss main body arranged in parallel.

[0007] The upper conversion component is connected to the main body of the upper truss;

[0008] An inclined beam is provided at an angle, and one end of the inclined beam is connected to the upper conversion member;

[0009] The lower conversion member is connected to the lower truss body and the steel pipe column, and the other end of the inclined beam is connected to the lower conversion member.

[0010] Optionally, the upper conversion component includes a conversion frame and a connecting plate, with two conversion frames symmetrically arranged on both sides of the connecting plate, and the tops of the conversion frames and the connecting plate being connected to the upper truss body.

[0011] Alternatively, the conversion frame may include an arc-shaped plate disposed at the bottom of the conversion frame.

[0012] Optionally, two of the lower conversion member and the inclined beam are provided, with each end of the inclined beam connected to the conversion frame and the lower conversion member, respectively.

[0013] Optionally, the lower conversion member is provided with a first connecting part and a second connecting part, the first connecting part being connected to the inclined beam, and the two adjacent sides of the second connecting part being connected to the steel pipe column and the lower truss body, respectively.

[0014] Alternatively, the axis of the first connecting portion is set at an angle to the axis of the second connecting portion.

[0015] Optionally, the upper truss body includes an upper corbel, an upper truss, and a pile foundation beam. The upper corbel is connected to the steel pipe column, and the two ends of the upper truss are respectively connected to the upper corbel and the pile foundation beam. The pile foundation beam is located in the middle of two adjacent steel pipe columns, and the upper transition member is connected to the pile foundation beam.

[0016] Optionally, the pile foundation beam includes an upper top plate, an intermediate plate, a lower bottom plate, and a support layer. The upper top plate is parallel to the lower bottom plate, and the intermediate plate and the support layer are both vertically sandwiched between the upper top plate and the lower bottom plate, with the support layer surrounding both sides of the intermediate plate.

[0017] Optionally, the lower truss body includes a lower corbel and a lower truss, the lower corbel is connected to the steel pipe column, both ends of the lower truss are respectively connected to the lower corbel, and the lower transition member is connected to the lower corbel and the steel pipe column.

[0018] Alternatively, the inclined beam can be configured as a square box girder.

[0019] The beneficial effects of this invention are:

[0020] In this invention, the upper transfer member disperses the pressure on the upper truss body to the inclined beam, which then transmits it to the lower transfer member, and finally to the connected steel column. This constitutes an effective force transmission path for the transfer truss. The combined forces of the upper transfer member, inclined beam, and lower transfer member effectively distribute the load, thereby improving the overall load-bearing capacity of the transfer truss. Simultaneously, the upper truss body can bear the load applied from above, while the lower truss body provides tensile force to counteract the horizontal component of the inclined beam, further enhancing the strength of the transfer truss in high-rise buildings.

[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] Because steel columns cannot be installed in the lobby of super high-rise buildings, and large-span beams in super high-rise buildings cannot meet the load-bearing requirements, a transfer floor is often added above the lobby to facilitate the installation of steel columns and reduce the local span for easier construction. Transfer trusses are commonly used in such applications. However, since the transfer truss is located on a lower floor but bears the load generated by a building tens or hundreds of meters high, the truss's own load-bearing capacity is crucial. Therefore, optimizing the distribution of the force transmission path of the transfer truss to reasonably distribute the load and improve its load-bearing capacity is an urgent problem to be solved.

[0041] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0042] like Figures 1-10As shown, this embodiment provides a conversion truss, including a truss body, an upper conversion member 40, a diagonal beam 50, and a lower conversion member 60. The truss body is located between two adjacent steel pipe columns 100, including an upper truss body and a lower truss body arranged in parallel. The upper conversion member 40 is connected to the upper truss body. The diagonal beam 50 is inclined and one end of the diagonal beam 50 is connected to the upper conversion member 40. The lower conversion member 60 is connected to the lower truss body and the steel pipe column 100, and the other end of the diagonal beam 50 is connected to the lower conversion member 60.

[0043] In this embodiment, the upper transfer member 40 can distribute the pressure on the upper truss body to the inclined beam 50, and then transfer it to the lower transfer member 60 through the inclined beam 50, and then to the steel pipe column 100 connected to it through the lower transfer member 60. This constitutes an effective force transmission path for the transfer truss, and the force is reasonably distributed with the cooperation of the upper transfer member 40, the inclined beam 50 and the lower transfer member 60, thereby improving the overall load-bearing capacity of the transfer truss. At the same time, the upper truss body can bear the load applied from above, and the lower truss body can provide tension to offset the horizontal component force of the inclined beam 50, further enhancing the strength of the transfer truss in super high-rise buildings.

[0044] The specific structure of the conversion truss in this embodiment will be described below.

[0045] like Figure 1 As shown, in this embodiment, the transfer truss includes an upper corbel 10, an upper truss 20, a pile foundation beam 30, an upper transfer member 40, a diagonal beam 50, a lower transfer member 60, a lower corbel 70, and a lower truss 80. The upper corbel 10, upper truss 20, and pile foundation beam 30 constitute the main body of the upper truss, while the lower corbel 70 and lower truss 80 constitute the main body of the lower truss. In this embodiment, the main bodies of the upper and lower trusses are arranged parallel to each other between two adjacent steel pipe columns 100. Optionally, two upper corbels 10, two upper trusses 20, two diagonal beams 50, two lower transfer members 60, and two lower corbels 70 are provided. Specifically, each steel pipe column 100 is connected from top to bottom to one upper corbel 10, one lower transfer member 60, and one lower corbel 70, wherein the lower transfer member 60 is simultaneously connected to the lower corbel 70 of the lower truss main body and the steel pipe column 100 to ensure a complete and stable force transmission path.

[0046] Furthermore, the two ends of the upper truss 20 are respectively connected to the upper corbel 10 and the pile foundation beam 30. The pile foundation beam 30 is located in the middle of two adjacent steel pipe columns 100, that is, the two steel pipe columns 100, the two upper corbels 10, and the two upper trusses 20 are all symmetrically arranged with respect to the pile foundation beam 30. Similarly, the two lower corbels 70 are also symmetrically arranged with respect to the pile foundation beam 30, and the two ends of the lower truss 80 are respectively connected to one lower corbel 70. Thus, the upper truss body and the lower truss body connect the two steel pipe columns 100 laterally. In this embodiment, the pile foundation beam 30 in the upper truss body is used to connect the upper steel pipe and bear the load force applied to the device by the upper steel pipe.

[0047] Furthermore, the top of the upper conversion member 40 is connected to the bottom of the pile foundation beam 30 of the upper truss main body, and the inclined beam 50 is inclined, with both ends of the inclined beam 50 connected to the upper conversion member 40 and the lower conversion member 60 respectively. Thus, the upper conversion member 40, the inclined beam 50, and the lower conversion member 60 can effectively distribute the load force of the pile foundation beam 30, that is, the load force of the pile foundation beam 30 is transferred along the two inclined beams 50 to the two lower conversion members 60, and under the action of the lower conversion members 60, it is transferred to the two steel pipe columns 100 and the two lower brackets 70 respectively. Under the action of the tension provided by the lower truss 80, the horizontal component force of the inclined beam 50 is offset, thereby realizing an effective force transmission path, improving the overall load-bearing capacity of the conversion truss in this embodiment, and enhancing the mechanical strength of the device itself.

[0048] like Figure 2 As shown, in this embodiment, the steel pipe column 100 includes an upper steel pipe column 101 and a lower steel pipe column 102. Optionally, the upper steel pipe column 101 and the lower steel pipe column 102 have the same diameter and are connected by welding in this embodiment, thereby ensuring the connection stability of the steel pipe column 100 and making it less prone to breakage under stress. Specifically, the upper bracket 10 is connected to the upper steel pipe column 101, and the lower bracket 70 is connected to the lower steel pipe column 102.

[0049] like Figure 3 As shown, the upper bracket 10 is made of I-beams and includes two first plates 11 and one second plate 12. Specifically, the second plate 12 is vertically sandwiched between the two parallel first plates 11. The first plates 11 have arc-shaped notches, the curvature of which matches the outer curvature of the upper steel pipe column 101. This allows the first plates 11 and the upper steel pipe column 101 to be tightly connected, ensuring the stability of the device during force transmission and reducing the influence of other factors. Furthermore, as... Figure 4 As shown, the upper truss 20 is made of I-beams and has a first hole 201 for stable connection of the reinforcing bars during subsequent operations.

[0050] like Figure 5 As shown, the pile foundation beam 30 includes an upper top plate 31, a middle plate 32, a lower bottom plate 33, a support layer 34, and a first reinforcing plate 35. The support layer 34 includes a first support plate 341 and a second support plate 342. A second hole 301 is provided on the upper top plate 31. Optionally, multiple second holes 301 are provided, connecting to structural frame steel columns. Optionally, the upper top plate 31 is parallel to the lower bottom plate 33, and the middle plate 32 and the support layer 34 are both vertically sandwiched between the upper top plate 31 and the lower bottom plate 33, with the support layer 34 surrounding both sides of the middle plate 32. Figure 5As shown, the first support plate 341 and the second support plate 342 are both parallel to the intermediate plate 32 and connected to the upper top plate 31 and the lower bottom plate 33. A closing plate is also provided between the first support plate 341 and the intermediate plate 32, thus forming a support space consisting of the first support plate 341, the second support plate 342, the closing plate, and the intermediate plate 32. Optionally, a support space is provided on both sides of the intermediate plate 32, providing vertical support to the upper top plate 31 and improving the overall load-bearing capacity of the pile foundation beam 30. Optionally, a first reinforcing plate 35 is provided on the intermediate plate 32 and connected to the upper top plate 31 and the lower bottom plate 33, thereby further improving the load-bearing capacity of the pile foundation beam 30.

[0051] like Figure 6 As shown, the upper conversion component 40 includes a conversion frame 41 and a connecting plate 42. Optionally, two conversion frames 41 are symmetrically arranged on opposite sides of the connecting plate 42, and the tops of both the conversion frames 41 and the connecting plate 42 are connected to the bottom of the pile foundation beam 30 of the upper truss body. Specifically, the conversion frame 41 consists of two side plates, a top plate, and an arc-shaped plate 411. In this embodiment, the two side plates are arranged in parallel and have an irregular shape. Optionally, the top plate is vertically sandwiched between the two side plates and is inclined relative to the top surface of the conversion frame 41. In this embodiment, the top surface of the conversion frame 41 is open, which facilitates the connection between the conversion frame 41 and the pile foundation beam 30 and is more conducive to the distribution and transmission of bearing capacity. Further, the arc-shaped plate 411 covers the bottom of the two side plates to improve the overall stability of the conversion frame 41. The curvature of the arc-shaped plate 411 is set as needed. Optionally, the connecting plate 42 is disposed between the two conversion frames 41 and seals one end of the conversion frame 41. The other end of the conversion frame 41 is used to connect the inclined beam 50 to complete the effective force transmission path.

[0052] Optionally, each inclined beam 50 is connected to a conversion frame 41 and a lower conversion component 60 at both ends. In this embodiment, the inclined beam 50 is set as a square box beam, and the conversion frame 41 connected to one end of the inclined beam 50 is also square and its size is adapted to the inclined beam 50.

[0053] like Figure 7As shown, the lower conversion member 60 is provided with a first connecting part 601 and a second connecting part 602. The first connecting part 601 is connected to the inclined beam 50, and the two adjacent sides of the second connecting part 602 are respectively connected to the steel pipe column 100 and the lower truss body. Specifically, the second connecting part 602 is connected to the lower section of the steel pipe column 102 and the lower bracket 70. Optionally, the first connecting part 601 is set as a square structure to fit the size of the inclined beam 50, thereby achieving a stable connection between the inclined beam 50 and the lower conversion member 60. Further, the axis of the first connecting part 601 is set at an angle to the axis of the second connecting part 602, and the extension surface of the first connecting part 601 gradually becomes parallel and connects to the extension surface of the second connecting part 602, thereby making the force transmission process more stable. Optionally, the lower conversion member 60 in this embodiment is an integral structure, making the structure more stable. Furthermore, the second connecting part 602 is provided with an arc-shaped notch, and the curvature of the arc-shaped notch is adapted to the outer curvature of the lower section steel pipe column 102. Thus, the lower conversion part 60 and the lower section steel pipe column 102 can be tightly connected, ensuring the stability of the device during force transmission and reducing the influence of other factors.

[0054] like Figure 8 and Figure 9 As shown, the lower bracket 70 includes an upper top plate 71, a middle plate 72, a lower bottom plate 73, a first side plate 74, a second side plate 75, and a second reinforcing plate 76. Optionally, the upper top plate 71 is parallel to the lower bottom plate 73, and the middle plate 72, first side plate 74, second side plate 75, and second reinforcing plate 76 are all vertically sandwiched between the upper top plate 71 and the lower bottom plate 73, thereby improving the load-bearing capacity of the lower bracket 70. Specifically, the first side plate 74 is parallel to the middle plate 72, and the second side plate 75 is vertically sandwiched between the first side plate 74 and the middle plate 72, thereby forming a load-bearing space. Optionally, a load-bearing space is provided on each side of the middle plate 72, providing vertical support for the lower bracket 70 and improving the overall load-bearing capacity of the lower bracket 70.

[0055] Optionally, a second reinforcing plate 76 is disposed on the intermediate plate 72 of the lower corbel and connected to the upper top plate 71 and the lower bottom plate 73 of the lower corbel, thereby further improving the load-bearing capacity of the lower corbel 70. Furthermore, both the upper top plate 71 and the lower bottom plate 73 of the lower corbel are provided with arc-shaped notches, and the curvature of the arc-shaped notches matches the outer curvature of the lower section steel pipe column 102. This ensures a tight connection between the upper top plate 71 and the lower bottom plate 73 of the lower corbel and the lower section steel pipe column 102, guaranteeing the stability of the device during force transmission and reducing the influence of other factors. Further, such as Figure 10 As shown, the lower truss 80 is made of I-beams, and a third hole 801 is provided on the lower truss 80 for the stable connection of the reinforcing bars during subsequent operations.

[0056] In this embodiment, the load-bearing capacity of the pile foundation beam 30 is distributed and transferred to the upper transfer member 40 and the upper truss 20, reducing the load on individual components. The upper truss 20 then transfers the load to the upper corbel 10, and subsequently to the upper steel pipe column 101, thus transferring the vertical load to the vertical load-bearing structure and ensuring structural safety. Furthermore, the connection between the upper transfer member 40 and the pile foundation beam 30 distributes the pressure on the pile foundation beam 30 to the inclined beam 50, and then to the lower transfer member 60, subsequently to the lower corbel 70, and finally to the lower steel pipe column 102, similarly transferring the vertical load to the vertical load-bearing structure and further ensuring structural safety. The connection between the lower truss 80 and the lower corbel 70 provides tension, offsetting the horizontal component of the inclined beam 50 and enhancing the strength of the transfer layer in the high-rise building. Simultaneously, since most of the components of the transfer truss in this embodiment are made of steel, they can be reused repeatedly, thereby reducing the cost of engineering operations.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
