Description

Technical Field

[0001] The present application relates to the field of building technology, and in particular to a truss, a plate member and a building member. Background Art

[0002] With the acceleration of urbanization, various types of buildings are increasing. Among them, trusses are widely used. Trusses are composed of upper chords and web members, or upper chords, lower chords and web members connected between the upper chords and lower chords. They usually have a plane or spatial structure of triangular units, mainly bear axial tension or pressure, and can make full use of the strength of the material.

[0003] In the related art, the top ends of the two web members are connected to each other and to the upper chord to form a triangular unit spatial structure. Therefore, the spacing between the bottom ends of the web members along the second direction (such as the horizontal direction) is shorter, resulting in a smaller force transmission area between the truss and the bottom plate structure, resulting in deformation and stress concentration when subjected to force, and a decrease in overall stability, resulting in poor bearing capacity and safety.

[0004] Under the condition of the same truss height, if the spacing between the bottom ends of the web members in the second direction (such as the horizontal direction) is to be increased to increase the force transmission area between the truss and the bottom plate structure, the angle between the top ends of the two web members will be too large, resulting in a reduction in the overall stability of the truss, making the truss more susceptible to deformation or collapse when subjected to external forces, resulting in poor bearing capacity and safety.

DETAILED DESCRIPTION

[0034] The embodiments of the present application are described below in conjunction with the drawings in the present application. It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0035] Those skilled in the art will appreciate that, unless expressly stated, the "said" and "the" used herein may also include plural forms. It should be further understood that the term "including" used in the specification of the present application refers to the presence of the features, integers, steps, operations, elements and / or components, but does not exclude the implementation of other features, information, data, steps, operations, elements, components and / or combinations thereof supported by the technical field. The term "and / or" used herein refers to at least one of the items defined by the term, for example, "A and / or B" may be implemented as "A", or as "B", or as "A and B".

[0036] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0037] The research and development ideas of this application include: in the related art, the top ends of the two webs are connected to form a vertex, and are connected to the upper chord to form a truss with a triangular unit space structure. The plane where the bottom ends of the two webs are located is called the bottom surface of the truss (in Figure 1a , Figure 1g or Figure 1h The straight line extending along the second direction at the bottom represents the bottom surface). The upper chord may be a steel upper chord, a concrete upper chord or a steel-concrete combination upper chord.

[0038] The bearing capacity of the truss is related to parameters such as the height of the truss, the angle between the web and the bottom surface, and the spacing of the bottom ends of the web along the second direction (hereinafter referred to as the bottom width of the truss).

[0039] The higher the truss is, the higher its load-bearing capacity is. Figure 1g As shown, the truss formed by the web member B is higher than the truss formed by the web member A. However, in actual engineering applications, the floor thickness is determined, and the truss height is also determined, so it is difficult to increase the bearing capacity of the truss by increasing the truss height.

[0040] Furthermore, the wider the bottom width of the truss is, the larger the force transmission area between the truss and the bottom plate structure is, and the better the bearing capacity and safety are. Figure 1g and Figure 1h As shown, the bottom width of the truss formed by the web member A is greater than the bottom width of the truss formed by the web member C. Therefore, it is possible to consider changing the load-bearing capacity of the truss by increasing the bottom width of the truss.

[0041] However, the larger the angle between the web and the bottom surface, the closer the web is to a vertical state, and the better the force transmission effect.

[0042] Therefore, if the load-bearing capacity of the truss is changed by increasing the bottom width of the truss while keeping the height of the truss fixed, the angle between the web and the bottom surface will inevitably decrease. Figure 1g The truss formed by the web member A in Figure 1h Compared with the truss formed by the web member C in the truss, the angle β formed by the web member A and the bottom surface is smaller than the angle α formed by the web member C and the bottom surface. This reduces the overall stability of the truss, making the truss more likely to deform or collapse when subjected to external forces, resulting in poor bearing capacity and safety of the truss.

[0043] The trusses, plate components and building components provided in this application are intended to solve the above technical problems in related technologies.

[0044] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. It should be noted that the following implementations can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different implementations will not be described repeatedly.

[0045] The present application embodiment provides a truss 100, the structural schematic diagram of the truss 100 is as shown in Figure 1a to Figure 2 As shown, the truss 100 includes a concrete upper chord 110 and a web member 120 .

[0046] The concrete upper chord 110 is in a strip shape and includes a main body 111 formed of concrete.

[0047] The web member 120 is wavy in shape, and its overall length direction is consistent with the first direction. The top end 121 of the web member 120 is fixed in the concrete upper chord 110. The first direction is consistent with the length direction of the concrete upper chord 110.

[0048] The two web members 120 are spaced and symmetrically arranged along the second direction, and their respective planes intersect with each other, 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 .

[0049] In this embodiment, the two webs 120 are arranged at intervals along the second direction and are symmetrically disposed, both facing the center line (eg Figure 1a The vertical dotted line in the middle) is inclined, that is, the top ends 121 of the two web members 120 correspond one to one along the second direction. The web member 120 is a planar wavy structure formed by bending a rod-shaped object back and forth. The planes where the two web members 120 are located intersect, and the intersection line formed is located above the upper chord 110 of the concrete. Compared with the technical solutions in the related art in which the planes where the two web members 120 are located are parallel or the top ends 121 of the web members 120 are connected, the embodiment of the present application can increase the spacing between the bottom ends 122 of the web members 120 under the condition of the same truss height, and increase the force transmission area between the bottom of the truss 100 and the plate structure 200 in the plate member formed by the bottom of the truss 100 and the plate structure 200, thereby improving the bearing capacity and stability of the plate member.

[0050] Moreover, compared with the technical solution of increasing the angle between the top ends 121 of the connected web bars 120 in the related art (such as Figure 1g The technical solution of increasing the angle between the web members A in the embodiment of the present application can ensure that the angle between the web member 120 and the center line is within a reasonable range, and can also increase the 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 bearing capacity and stability of the plate member.

[0051] Alternatively, if Figure 1a and Figure 2As shown, the first direction is consistent with the length direction of the concrete upper chord 110, which may also be referred to as the longitudinal direction, and the second direction is consistent with the width direction of the concrete upper chord 110, which may also be referred to as the transverse direction.

[0052] It is understandable that Figure 1a similar, Figure 1b-Figure 1c , Figure 3a , Figure 6a-Figure 16c , Fig.21 as well as Figure 23-Figure 25 The vertical dotted lines in the middle refer to the center lines of the structures shown in the figures.

[0053] In some possible implementations, the angle α between the web bar 120 and the plane where the bottom ends of the two web bars 120 are located is between 60 degrees and 89 degrees.

[0054] In this embodiment, the 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 bearing capacity of the truss 100.

[0055] Optionally, a cross section of the main body 111 along the second direction includes a rectangle, a trapezoid, an oblong, or an irregular polygon.

[0056] In this embodiment, the cross-section of the main body 111 of the concrete upper chord 110 in the second direction can be designed in various shapes as required, such as Figure 1a The rectangle shown, Figure 1b The trapezoid shown, Figure 1c The oblong shape shown and Figure 1d and Figure 1e For ease of understanding, this application only describes the different structures between various embodiments, and the structures of other parts not covered are the same or similar and will not be repeated here.

[0057] Alternatively, if Figure 1b As shown, the cross section of the main body 111 along the second direction is a trapezoid. During the manufacturing process, concrete is poured in the inverted trapezoidal mold, and after molding, it is flipped to form a regular trapezoidal main body 111. The inverted trapezoidal mold is wide at the top and narrow at the bottom, which is easier to demould and can reduce the difficulty of manufacturing.

[0058] Moreover, if Figure 1fAs shown, the two waists of the main body 111 of the regular trapezoid are symmetrical, and the angle between the two waists is just the same as the angle between the two web members 120 of the truss 100, so that when multiple trusses 100 are stacked, the concrete upper chord 110 of the bottom truss 100 can just fit 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 guide and limit each other to a certain extent, thereby improving the stacking efficiency and saving the stacking space.

[0059] In some possible embodiments, Figure 3a-Figure 3b , Figure 6a-Figure 8 As shown, the concrete upper chord 110 further includes: a metal component 112 covering at least a portion of the outer surface of the main body 111 .

[0060] The bottom of the metal component 112 is open, and the top end 121 of the web 120 is inserted into the main body 111 through the opening of the metal component 112 .

[0061] In this embodiment, the main body 111 formed by the metal component 112 and the concrete can form an open-type steel tube concrete upper chord 110 rod, or a steel-concrete combined compression rod, which can improve the strength of the concrete upper chord 110, thereby improving the bearing capacity and tensile resistance of the concrete upper chord 110.

[0062] Optionally, the metal member 112 comprises an open-ended steel tube.

[0063] In some possible embodiments, Figure 6a As shown, the cross section of the metal component 112 is C-shaped.

[0064] Optionally, the metal member 112 includes a channel steel or a C-shaped steel.

[0065] In some possible embodiments, Figure 3a , Figure 3b , Figure 6b or Figure 8 As shown, the edge of the bottom opening of the metal component 112 has a bent portion 113 bent toward the inside of the metal component 112 .

[0066] The bent portion 113 is embedded in the main body 111 .

[0067] In this embodiment, the edge of the opening of the metal component 112 is bent toward the inside of the main body 111 to form a bent portion 113 and embedded in the main body 111, which can enhance the bonding ability between the metal component 112 and the main body 111, thereby ensuring the good reliability of the concrete upper chord 110 itself.

[0068] refer to Figure 3a or Figure 8The bent portion 113 can be obtained by bending the edge of the metal component 112 at a position 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.

[0069] refer to Figure 3b or Figure 6b The bent portion 113 can be obtained by bending the edge of the metal component 112 at a position closer to the center line of the main body. The bottom of the metal component 112 is opened to facilitate the insertion of the web member 120 into the concrete upper chord 110.

[0070] Optionally, the bending angle of the bending portion 113 is adjustable, depending on the manufacturing difficulty or design requirements.

[0071] In some possible embodiments, Figure 3a , Figure 4 and Figure 5 As shown, a plurality of groups of sequentially connected convex portions 1131 and concave portions 1132 are formed at the edge of the bending portion 113 .

[0072] In this embodiment, the edge has an uneven structure, and the concrete forming the main body 111 also forms a complementary uneven structure at the edge of the bending portion 113, which can enhance the gripping force between the bending portion 113 and the main body 111, thereby ensuring the good reliability of the concrete upper chord 110 itself.

[0073] Alternatively, if Figure 5 As shown, the edge of the bent portion 113 is serrated.

[0074] In some possible embodiments, the truss 100 further includes: at least one first steel bar 130 .

[0075] like Fig.10 As shown, at least one first steel bar 130 is disposed in the main body 111 along a first direction and is located between top ends 121 of different web members 120 .

[0076] In some possible embodiments, Fig. 9 As shown, the truss 100 further includes: at least one second reinforcement bar 131. The at least one second reinforcement bar 131 is located outside the top end of the at least one web member 120.

The web member 120 is a planar wavy structure formed by bending a rod-shaped object back and forth. The planes where the two web members 120 are located intersect, and the intersection line formed is located above the concrete upper chord 110. Compared with the technical solution in the related art in which the inclination is unchanged and the top ends 121 of the web members 120 are connected, the embodiment of the present application can increase the spacing between the bottom ends 122 of the web members 120, and in the plate member formed by the bottom of the truss 100 and the plate structure 200, increase the force transmission area between the bottom of the truss 100 and the plate structure 200, thereby improving the bearing capacity and stability of the plate member.

[0185] 2. Compared with the technical solution of increasing the angle between the top end 121 of the web member 120 in the related art, the embodiment of the present application can ensure that the angle between the web member 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 bearing capacity and stability of the plate component.

[0186] 3. In the embodiment of the present application, the main body 111 formed by the metal component 112 and the concrete can form an open-type steel tube concrete upper chord 110 rod, or a steel-concrete combined compression rod, which can improve the strength of the concrete upper chord 110, thereby improving the bearing capacity and tensile resistance of the concrete upper chord 110.

[0187] 4. In the embodiment of the present application, the edge of the opening of the metal component 112 is bent toward the inside of the main body 111 to form a bent portion 113 and embedded in the main body 111, which can enhance the bonding ability between the metal component 112 and the main body 111, thereby ensuring the good reliability of the concrete upper chord 110 itself.

[0188] 5. The position of the steel bars in the main body 111 can be flexibly set according to design requirements, and can be located outside the web member 120 or inside the web member 120 to act as negative moment steel bars. In addition, the steel bars can be connected to the web member 120 to enhance the relative stability between the first steel bar 130 and the web member 120, and between the second steel bar 131 and the web member 120, thereby improving the strength of the concrete upper chord 110.

[0189] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0190] The above is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the technical concept of the scheme of the present application, other similar implementation methods based on the technical ideas of the present application are also within the protection scope of the embodiments of the present application.
