Description

Technical Field

[0001] This application relates to the field of building technology, and more specifically, to a truss, plate component, and building component. Background Technology

[0002] With the acceleration of urbanization, various types of buildings are increasing. Among them, trusses are widely used. A truss consists of a top chord and web members, or a top chord, a bottom chord, and web members connecting the top and bottom chords. It is usually a planar or spatial structure with triangular units, mainly bearing axial tension or compression, and can make full use of the strength of the material.

[0003] In related technologies, the top ends of two web members are connected to the upper chord to form a spatial structure of a triangular unit. Therefore, the spacing between the bottom ends of the web members along the second direction (such as the transverse direction) is relatively short, resulting in a smaller force transmission area between the truss and the bottom plate structure. This leads to deformation and stress concentration under load, reduced overall stability, and poor load-bearing capacity and safety.

[0004] With the same truss height, if the spacing of the bottom end of the web members along the second direction (such as the transverse direction) is increased to increase the force transmission area between the truss and the bottom plate structure, the included angle between the top ends of the two web members will be too large, resulting in a decrease in the overall stability of the truss. This makes the truss more prone to deformation or collapse when subjected to external forces, resulting in poor load-bearing capacity and safety. Utility Model Content

The web members are planar wave-shaped structures formed by bending rods back and forth. The planes containing the two web members intersect, and the intersection line is located above the upper chord of the concrete. Compared to related technologies where the inclination remains constant and the tops of the web members are connected, this embodiment increases the spacing between the bottom ends of the web members at the same truss height. This increases the force transmission area between the truss bottom and the plate structure in the plate member formed by the truss bottom and the plate structure, thereby improving the load-bearing capacity and stability of the plate member.

[0071] Moreover, compared with the technical solutions in related technologies that increase the included angle between the tops of the web members, the embodiments of this application can ensure that the included angle between the web members and the centerline is within a reasonable range, which can effectively reduce the risk of truss deformation or collapse, thereby improving the load-bearing capacity and stability of the plate components.

[0137] The embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions of the embodiments of this application.

[0138] Those skilled in the art will understand that, unless specifically stated otherwise, the terms "described" and "the" as used herein may also include plural forms. It should be further understood that the term "comprising" as used in the specification of this application means the presence of the stated features, integers, steps, operations, elements, and / or components, but does not exclude other features, information, data, steps, operations, elements, components, and / or combinations thereof supported by the art. The term "and / or" as used herein refers to at least one of the items defined by the term; for example, "A and / or B" can be implemented as "A," or as "B," or as "A and B."

[0139] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0140] The research and development concept of this application includes: In related technologies, the top ends of two web members are connected to form a vertex, which is then connected to the upper chord to form a truss with a spatial structure of triangular units. The plane containing the bottom ends of the two web members is called the base of the truss (in...). Figure 1a , Figure 1g or Figure 1h The bottom surface is represented by the straight line extending along the second direction from the bottom. The top chord can be a steel top chord, a concrete top chord, or a composite steel-concrete top chord.

[0141] The load-bearing capacity of a truss is related to parameters such as the height of the truss, the angle between the web members and the bottom surface, and the spacing of the bottom ends of the web members along the second direction (hereinafter referred to as the bottom width of the truss).

[0142] The higher the truss, the greater its load-bearing capacity. For example... Figure 1g As shown, the truss formed by web member B is higher than the truss formed by web member A. However, in practical engineering applications, the floor slab thickness and truss height are fixed, making it difficult to increase the load-bearing capacity of the truss by increasing the truss height.

[0143] Furthermore, the wider the base of the truss, the larger the force transmission area between the truss and the bottom plate structure, resulting in better load-bearing capacity and safety. For example... Figure 1g and Figure 1h As shown, the base width of the truss formed by web member A is greater than the base width of the truss formed by web member C. Therefore, the load-bearing capacity of the truss can be changed by increasing the base width of the truss.

[0144] However, the larger the angle between the web member and the bottom surface, the closer the web member is to a vertical state, and the better the force transmission effect.

[0145] Therefore, if the load-bearing capacity of a truss is changed by increasing its base width while keeping the truss height constant, it will inevitably lead to a decrease in the angle between the web members and the base. For example... Figure 1g The truss formed by the web member A in the middle, and Figure 1hCompared to the truss formed by the web members C, the angle β formed by the web member A and the base is smaller than the angle α formed by the web member C and the base. This leads to a decrease in the overall stability of the truss, making it more prone to deformation or collapse when subjected to external forces, resulting in poorer load-bearing capacity and safety.

[0146] The truss, plate components, and building components provided in this application are intended to solve the aforementioned technical problems in related technologies.

[0147] The technical solution of this application and how it solves the above-mentioned technical problems are described in detail below with specific embodiments. It should be noted that the following embodiments can be referenced, borrowed, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0148] This application provides a truss 100, the structural schematic diagram of which is shown below. Figures 1a to 2 As shown, the truss 100 includes a concrete top chord 110 and web members 120.

[0149] The concrete upper chord 110 is strip-shaped and includes the main body 111 formed of concrete.

[0150] The web member 120 is wavy, and its overall length direction is consistent with the first direction. The top end 121 of the web member 120 is fixed inside the concrete upper chord 110. The first direction is consistent with the length direction of the concrete upper chord 110.

[0151] Two web members 120 are arranged symmetrically and spaced apart along the second direction, and their respective planes intersect, with the intersection line located above the concrete upper chord 110; the second direction is consistent with the width direction of the concrete upper chord 110.

[0152] In this embodiment, the two web members 120 are arranged symmetrically along the second direction and are both oriented towards the center line (e.g., Figure 1a The vertical dotted line in the middle is inclined, meaning that the tops 121 of the two web members 120 correspond one-to-one along the second direction. The web members 120 are planar wave-shaped structures formed by bending rods back and forth. The planes where the two web members 120 are located intersect, and the intersection line is located above the concrete upper chord 110. Compared with the related technologies where the planes where the two web members 120 are located are parallel or the tops 121 of the web members 120 are connected, the embodiment of this application can increase the spacing between the bottom ends 122 of the web members 120 under the same truss height. In the plate member formed by the bottom of the truss 100 and the plate structure 200, the force transmission area between the bottom of the truss 100 and the plate structure 200 is increased, thereby improving the load-bearing capacity and stability of the plate member.

[0153] Moreover, compared to the technical solution of increasing the included angle between the top ends 121 of the connected web members 120 in related technologies (such as...), Figure 1g The technical solution of increasing the included angle between the web members A) in this application embodiment can ensure that the included angle between the web member 120 and the center line is within a reasonable range, and can also increase the included angle between the web member 120 and the bottom surface, which can effectively reduce the risk of deformation or collapse of the truss 100, thereby improving the load-bearing capacity and stability of the plate components.

[0154] Optionally, such as Figure 1a and Figure 2 As shown, the first direction is consistent with the length direction of the concrete upper chord 110, which can also be called the longitudinal direction, and the second direction is consistent with the width direction of the concrete upper chord 110, which can also be called the transverse direction.

[0155] Understandably, with Figure 1a similar, Figures 1b-1c , Figure 3a , Figures 6a-16c , Figure 21 as well as Figures 23-25 The vertical dashed lines in the middle all refer to the center lines of the structures shown in each figure.

[0156] In some possible implementations, the angle α between the web member 120 and the plane containing the bottom ends of the two web members 120 is between 60 degrees and 89 degrees.

[0157] In this embodiment, the included angle α between the web member 120 and the bottom surface is between 60 degrees and 89 degrees, which can increase the force transmission effect of the web member 120 while ensuring that the bottom width of the truss 100 is fixed, thereby improving the load-bearing capacity of the truss 100.

[0158] Optionally, the cross-section of the main body 111 along the second direction includes a rectangle, trapezoid, oblong or irregular polygon.

[0159] In this embodiment, the cross-section of the main body 111 of the concrete upper chord 110 in the second direction can be designed with various shapes as needed, such as... Figure 1a The rectangle shown Figure 1b The trapezoid shown Figure 1c The oblong shape shown and Figure 1d and Figure 1e The polygon shown is an example. For ease of understanding, this application only describes the different structures between various embodiments; other structures that are not covered herein are the same or similar and will not be described in detail here.

[0160] Optionally, such as Figure 1b As shown, the main body 111 has a trapezoidal cross-section along the second direction. During the manufacturing process, concrete is poured into an inverted trapezoidal mold, and after molding, it is flipped to form a regular trapezoidal main body 111. The inverted trapezoidal mold is wider at the top and narrower at the bottom, making demolding easier and reducing manufacturing difficulty.

[0161] Moreover, such as Figure 1f As shown, the two legs of the trapezoidal main body 111 are symmetrical, and the included angle between the two legs is exactly the same as the included angle between the two web members 120 of the truss 100. This ensures that when multiple trusses 100 are stacked, the concrete upper chord 110 of the bottom truss 100 can be precisely inserted between the two web members 120 of the top truss 100. During the stacking process, the two web members 120 of the top truss 100 and the main body 111 of the bottom truss 100 can play a certain guiding and limiting role for each other, thereby improving stacking efficiency and saving stacking space.

[0162] In some possible embodiments, such as Figures 3a-3b , Figures 6a-8 As shown, the concrete upper chord 110 also includes a metal member 112 covering at least a portion of the outer surface of the main body 111.

[0163] The bottom opening of the metal component 112 allows the top end 121 of the web member 120 to be inserted into the main body 111 through the opening of the metal component 112.

[0164] In this embodiment, the metal component 112 and the main body 111 formed by concrete can form an open-type steel-concrete composite upper chord 110, or steel-concrete composite compression member, which can improve the strength of the concrete upper chord 110, thereby improving the load-bearing capacity and tensile capacity of the concrete upper chord 110.

[0165] Optionally, the metal component 112 includes an open steel pipe.

[0166] In some possible embodiments, such as Figure 6a As shown, the cross-section of the metal component 112 is C-shaped.

[0167] Optionally, the metal component 112 includes channel steel or C-shaped steel.

[0168] In some possible embodiments, such as Figure 3a , Figure 3b , Figure 6b or Figure 8 As shown, the metal member 112 has a bent portion 113 at the edge of the bottom opening that bends toward the inside of the metal member 112.

[0169] The bent portion 113 is embedded within the main body portion 111.

[0170] In this embodiment, the edge of the opening of the metal component 112 is bent into the body portion 111 to form a bent portion 113 and embedded in the body portion 111, which can enhance the bonding ability between the metal component 112 and the body portion 111, thereby ensuring the good reliability of the concrete upper chord 110 itself.

[0171] refer to Figure 3a or Figure 8The bent portion 113 can be obtained by bending the edge of the metal component 112 closer to the edge of the main body, which can avoid the position of the web member 120 and prevent the metal component 112 from interfering with the web member 120 inserted into the concrete upper chord 110.

[0172] refer to Figure 3b or Figure 6b The bent portion 113 can be obtained by bending the edge of the metal component 112 closer to the center line of the main body. The bottom of the metal component 112 has an opening to facilitate the insertion of the web member 120 into the concrete upper chord 110.

[0173] Optionally, the bending angle of the bending portion 113 is adjustable, depending on the manufacturing difficulty or design requirements.

[0174] In some possible embodiments, such as Figure 3a , Figure 4 and Figure 5 As shown, multiple sets of sequentially connected protrusions 1131 and concave portions 1132 are formed at the edge of the bent portion 113.

[0175] In this embodiment, the edge has an uneven structure, and the concrete forming the main body 111 also has a complementary uneven structure at the edge of the bending part 113, which can enhance the gripping force between the bending part 113 and the main body 111, thereby ensuring the good reliability of the concrete upper chord 110 itself.

[0176] Optionally, such as Figure 5 As shown, the edge of the bent portion 113 is serrated.

[0177] In some possible embodiments, the truss 100 further includes at least one first reinforcing bar 130.

[0178] like Figure 10 As shown, at least one first reinforcing bar 130 is disposed in the main body 111 along the first direction, located between the top ends 121 of different web members 120.

[0179] In some possible embodiments, such as Figure 9 As shown, the truss 100 also includes at least one second reinforcing bar 131. The at least one second reinforcing bar 131 is located outside the top of at least one web member 120.

[0180] In this embodiment, the position of the reinforcing bars inside the main body 111 can be flexibly set according to design requirements. They can be located outside the web member 120 or inside the web member 120, serving as negative moment reinforcing bars. Furthermore, they can be connected to the web member 120 to enhance the relative stability between the first reinforcing bar 130 and the web member 120, and between the second reinforcing bar 131 and the web member 120, thereby improving the strength of the concrete upper chord 110.

[0181] It is understood that, in the embodiments of this application, the outer side of the web member 120 refers to the direction toward the left and right sides of the truss 100, and the inner side of the web member 120 refers to the direction toward the interior of the truss 100.

[0182] Optionally, such as Figures 17-20 As shown, the web member 120 is a planar wavy structure formed by bending a rod back and forth. The continuous bending process of the web member 120 can be achieved using an automated production line for the steel truss 100. Both the top end 121 and the bottom end 122 of the web member 120 include a reverse bending structure, which can be either arc-shaped or straight. Within the same web member 120, the reverse bending structure can simultaneously include both arc-shaped and straight sections, depending on the specific circumstances.

[0183] Moreover, there can be multiple first reinforcing bars 130, all symmetrically arranged about the center line, which helps to ensure the structural stability of the truss 100.

[0184] In some possible embodiments, such as Figures 11-15 As shown, the truss 100 also includes at least one third reinforcing bar 140.

[0185] At least one third reinforcing bar 140 is disposed in the main body 111 along the second direction and is connected to at least one of the web member 120 and the first reinforcing bar 130.

[0186] In this embodiment, the third reinforcing bar 140 can be connected to the web member 120, or to the first reinforcing bar 130, or to both the web member 120 and the first reinforcing bar 130, thereby improving the strength of the concrete upper chord 110.

[0187] The embodiments provided in this application will now be described with reference to the accompanying drawings. For ease of understanding, this application only describes the different structures between various embodiments; other structures that are not covered herein are the same or similar and will not be described in detail here.

[0188] In some possible embodiments, such as Figure 11 As shown, the third reinforcing bar 140 is connected to the top end 121 of the two web members 120 in a one-to-one correspondence.

[0189] In some possible embodiments, such as Figure 12 As shown, a first reinforcing bar 130 is installed in the concrete upper chord 110. The first reinforcing bar 130 is located between the top 121 of the two web members 120 and is installed below the third reinforcing bar 140 and welded to the third reinforcing bar 140.

[0190] In some possible embodiments, such as Figure 13As shown, two first reinforcing bars 130 are set in the concrete upper chord 110. The two first reinforcing bars 130 are spaced between the top 121 of the two web members 120 and are set below the third reinforcing bar 140 and welded to the third reinforcing bar 140.

[0191] In some possible embodiments, such as Figure 14 As shown, two second reinforcing bars 131 are installed inside the concrete upper chord 110. The two second reinforcing bars 131 are located outside the top 121 of the two web members 120 and below the third reinforcing bar 140, and are welded to the third reinforcing bar 140 and the top 121 of the web member 120.

[0192] In some possible embodiments, such as Figure 15 As shown, within the concrete upper chord 110, two second reinforcing bars 131 are positioned outside the top 121 of the two web members 120 and below the third reinforcing bar 140, and are welded to the third reinforcing bar 140 and the top 121 of the web member 120. A first reinforcing bar 130 is positioned between the top 121 of the two web members 120 and above the third reinforcing bar 140, and is welded to the third reinforcing bar 140 and the top 121 of the web member 120.

[0193] Moreover, there can be multiple third reinforcing bars 140, all symmetrically arranged about the center line, which helps to ensure the structural stability of the truss 100.

[0194] Furthermore, the third reinforcing bar 140 is connected to the top 121 of both web members 120, connecting the two web members 120 into one unit, which also facilitates positioning and makes it easier to manufacture the truss 100.

[0195] In addition, the web member 120, the second reinforcing bar 131 and the third reinforcing bar 140 can be connected to each other to form a woven structure, making the overall structure more stable and the stress more reasonable. During hoisting, the reverse bending structure at the top of the web member 120 121 can be used as a hoisting point, which facilitates transportation and disassembly.

[0196] In some possible embodiments, such as Figure 16a As shown, the truss 100 also includes a first lower chord 150.

[0197] The first lower chord rib 150 is located on the outside of the web member 120 and is connected to multiple bottom ends of the web member 120. The first lower chord rib 150 extends along a first direction.

[0198] In some possible embodiments, such as Figure 16b As shown, the truss 100 also includes a second lower chord 160.

[0199] The second lower chord 160 is located on the outside of the web member 120 and is connected to multiple bottom ends of the web member 120 at a designed distance. The second lower chord 160 extends along the first direction.

[0200] In the embodiments provided in this application, the lower chord of the truss 100 is formed by steel bars, including at least one lower chord bar, which is disposed on the outside of the web member 120, so that the truss 100 forms a spatial structure.

[0201] When truss 100 has multiple types of bottom chord reinforcement, such as Figure 16c As shown, if there is both a first lower chord rib 150 and a second lower chord rib 160, then the various lower chord ribs are evenly spaced on the outside of the web member 120, and the various lower chord ribs can be arranged in parallel.

[0202] Optionally, the first reinforcing bar 130, the second reinforcing bar 131, the third reinforcing bar 140, the first lower chord bar 150, and the second lower chord bar 160 may each include at least one of prestressed reinforcing bars, prestressed steel strands, or prestressed steel wires, which can enhance the crack resistance and load-bearing capacity of the concrete upper chord 110 and reduce deflection.

[0203] It should be noted that, Figures 1a-3b as well as Figures 6a-16c A total of twenty-two schematic diagrams of the truss 100 in various embodiments are shown. For ease of understanding, this application only describes the different structures between the various embodiments. Other structures that are not covered are the same or similar and will not be described in detail here.

[0204] It should be noted that, Figures 17-20 This is a side view structural diagram of four types of web members 120 provided in the embodiments of this application. In the various trusses 100 provided in the embodiments of this application, the web members 120 can all be... Figures 17-20 At least one of the four types of web members 120 provided.

The plate component provided in this embodiment includes any of the trusses 100 provided in the above embodiments, and their implementation principles are similar, so they will not be described again here.

[0207] In this embodiment, at least one of the bottom end of the truss 100 and the first lower chord 150 is fixedly connected to the plate structure 200 to bear the lower tension.

[0208] In some possible embodiments, such as Figure 21 and Figure 22 As shown, the slab structure 200 includes: a concrete base slab 210 and a mesh structure (not shown in the figure).

[0209] The concrete base slab 210 is made of poured concrete.

[0210] The mesh structure is laid inside the concrete base slab 210.

[0211] The bottom end of the web member 120 of the truss 100 is inserted into the concrete base plate 210 and fixedly connected to the mesh structure, forming a plate component including a composite plate.

[0217] The fifth reinforcing bar 230 is set in the concrete base slab 210 along the first direction and is erected on the fourth reinforcing bar 220.

[0218] In this embodiment, multiple fourth reinforcing bars 220 pass laterally through the reverse bending structure at the bottom of the two web members 120, and multiple fifth reinforcing bars 230 are longitudinally arranged on the multiple fourth reinforcing bars 220.

The truss 100 can then be placed upside down in a rib mold, and high-strength concrete can be poured into the rib mold to form the concrete upper chord 110. Alternatively, the metal component 112 can be used directly as a mold, and high-strength concrete can be poured into the metal component 112 to form the concrete upper chord 110.

[0220] Optionally, the fourth reinforcing bar 220 and the fifth reinforcing bar 230 may each include at least one of prestressed reinforcing bars, prestressed steel strands or prestressed steel wires, which can enhance the crack resistance and load-bearing capacity of the concrete upper chord 110 and reduce deflection.

[0288] 1. In this embodiment of the application, the two web members 120 are arranged symmetrically along the second direction and are both oriented towards the center line (e.g., Figure 1a The vertical dotted line in the middle is inclined, meaning that the tops 121 of the two web members 120 correspond one-to-one along the second direction. The web members 120 are planar wave-shaped structures formed by bending rods back and forth. The planes containing the two web members 120 intersect, and the intersection line is located above the concrete upper chord 110. Compared with the related technology where the inclination is unchanged and the tops 121 of the web members 120 are connected, the embodiment of this application can increase the spacing between the bottom ends 122 of the web members 120. In the plate member formed by the bottom of the truss 100 and the plate structure 200, the force transmission area between the bottom of the truss 100 and the plate structure 200 is increased, thereby improving the load-bearing capacity and stability of the plate member.

Compared with the related technologies that increase the included angle between the top ends 121 of the web members 120, the embodiment of this application can ensure that the included angle between the web members 120 and the center line is within a reasonable range, which can effectively reduce the risk of deformation or collapse of the truss 100, thereby improving the load-bearing capacity and stability of the plate components.

[0290] 3. In the embodiments of this application, the metal component 112 and the main body 111 formed by concrete can form an open-type steel-concrete composite upper chord 110 bar, or steel-concrete composite compression bar, which can improve the strength of the concrete upper chord 110, thereby improving the load-bearing capacity and tensile capacity of the concrete upper chord 110.

[0291] 4. In this embodiment, the edge of the opening of the metal component 112 is bent into the body part 111 to form a bent part 113 and embedded in the body part 111, which can enhance the bonding ability between the metal component 112 and the body part 111, thereby ensuring the good reliability of the concrete upper chord 110 itself.

[0292] 5. The position of the reinforcing bars inside the main body 111 can be flexibly set according to design requirements. They can be located outside or inside the web members 120, serving as negative moment reinforcement. Furthermore, they can be connected to the web members 120 to enhance the relative stability between the first reinforcing bar 130 and the web members 120, and between the second reinforcing bar 131 and the web members 120, thereby improving the strength of the concrete upper chord 110.
