Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a roof truss. Background Technology

[0002] In the architectural structure of large-span main factory buildings, tubular truss roof trusses are widely used due to their advantages such as reasonable stress distribution and strong span adaptability. To ensure the overall stability of the tubular truss roof truss, upper and lower chord horizontal supports are usually arranged at both ends of the roof truss. These horizontal supports connect adjacent roof trusses into a whole, thereby improving the structure's resistance to lateral displacement and overall stiffness.

[0003] However, in actual construction, large-span tubular truss roof trusses need to be pre-arched according to design requirements during the fabrication stage to offset deformation after the subsequent roof load is applied. But after the roof trusses are hoisted into place, the roof load has not yet been fully applied. At this time, it is difficult to keep the actual installation elevation of adjacent roof trusses consistent, that is, adjacent roof trusses are not on the same horizontal plane. This causes the connection points at both ends of the upper and lower chord horizontal supports to be unable to be precisely aligned, which greatly increases the difficulty of installing the horizontal supports. This not only prolongs the construction period, but may also affect the structural stability due to insufficient installation accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a roof truss to solve the technical problem that after the roof truss is hoisted into place, the connection points of the upper and lower chord horizontal supports cannot be accurately aligned, which greatly increases the difficulty of installing the horizontal supports, not only prolongs the construction period, but also results in insufficient installation accuracy, thereby reducing the structural stability.

[0005] To achieve the above objectives, this utility model provides a roof truss, including a truss assembly, two fixing components, and multiple purlins. The truss assembly is horizontally arranged, and the truss assembly has fixing components and multiple purlins spaced apart along a second direction on both sides along a first direction. The purlins extend along the first direction, with one end connected to the side of the truss assembly relative to the first direction and the other end connected to the side of the fixing components relative to the first direction.

[0006] Optionally, the purlin includes a web and two flanges, the two flanges being spaced apart in the vertical direction, the web being disposed between the two flanges and connected to the two flanges.

[0007] Optionally, the purlin further includes two side plates, which are respectively disposed on both sides of the web along the second direction and located between the two wing plates, and the side plates are connected to the two wing plates.

[0008] Optionally, it also includes a plurality of connecting blocks that correspond one-to-one with the purlins. The connecting blocks are located on the side of the fixing component relative to the first direction. The side of the connecting block facing the purlin is provided with a connecting groove. The connecting groove penetrates the top and bottom surfaces of the connecting block in the vertical direction. The web plate is inserted into the connecting groove and connected to the connecting block.

[0009] Optionally, it also includes a plurality of embedded parts corresponding one-to-one with the purlins. The embedded parts are provided on the side of the fixing component relative to the first direction. The side of the embedded parts facing the purlins is provided with a connecting plane, and the purlins are connected to the connecting plane.

[0010] Optionally, it also includes a plurality of first tie rods extending along a second direction, each of the purlins having a through hole extending along the second direction, the first tie rods passing through the through holes of the plurality of purlins and connected to the through holes.

[0011] Optionally, the purlin is provided with a plurality of through holes spaced apart along a first direction, and each through hole on the purlin corresponds to one of the first tie rods.

[0012] Optionally, it also includes a plurality of second tie rods and a plurality of third tie rods extending horizontally. Two second tie rods are respectively disposed on both sides of the first tie rod closest to the fixing component along the first direction. One end of the second tie rod is connected to one end of the first tie rod, and the other end is connected to the side of the fixing component relative to the first direction. Two third tie rods are respectively disposed on both sides of the first tie rod closest to the truss component along the first direction. One end of the third tie rod is connected to one end of the first tie rod, and the other end is connected to the side of the truss component relative to the first direction.

[0013] Optionally, the truss assembly includes a first truss extending along a plurality of first directions and a plurality of second trusses extending along a second direction, the plurality of first trusses being spaced apart along the second direction, the plurality of second trusses being spaced apart along the first direction, any first truss connecting to each of the second trusses, any second truss connecting to each of the first trusses, and one end of the purlin being connected to the side of the second truss relative to the first direction.

[0014] Optionally, the fixing assembly includes a plurality of vertically arranged beams and a plurality of horizontal beams extending along a second direction. The plurality of beams are spaced apart along the second direction, and the horizontal beam is provided between two adjacent beams. The two ends of the horizontal beam are connected to the sides of the two adjacent beams relative to the second direction. One end of a portion of the purlins is connected to the side of the beam relative to the first direction, and one end of another portion of the purlins is connected to the side of the horizontal beam relative to the first direction.

[0015] Compared with the prior art, the roof truss implemented in this utility model has the following advantages: In this utility model's roof truss, a truss assembly is located between two fixed components. Multiple purlins, spaced apart in a second direction and extending along a first direction, connect the sides of the truss assembly and the fixed components. The truss assembly is horizontally connected to the fixed components via the purlins. The specific construction process is as follows: First, one end of each purlin is connected (possibly welded) to the side of the truss assembly relative to the first direction. Then, the truss assembly is hoisted to a designated height, keeping the crossbeam assembly horizontal, and the other end of each purlin is aligned with the side of the fixed component relative to the first direction. Next, the purlins are connected (possibly welded) to the fixed components, thus achieving the connection between the truss assembly and the fixed components. Since the truss assembly does not need to be mounted on the top surface of the fixed components for docking during this process, the pre-cambering has minimal impact on the construction of the roof truss. In summary, the roof truss of this utility model has lower construction difficulty and a shorter construction period, effectively ensuring the connection accuracy between the truss assembly and the fixed components, thereby ensuring the stability of the roof truss structure.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and 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 utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] like Figures 1 to 5 As shown, a roof truss of this utility model includes a truss assembly 1, two fixing components 3, and multiple purlins 2. The truss assembly 1 is horizontally arranged. The truss assembly 1 has fixing components 3 and multiple purlins 2 spaced apart along a second direction on both sides along a first direction. The purlins 2 extend along the first direction. One end of the purlin 2 is connected to the side of the truss assembly 1 relative to the first direction, and the other end is connected to the side of the fixing components 3 relative to the first direction.

[0026] In the above technical solution, the truss assembly 1 is located between two fixed assemblies 3. Multiple purlins 2, spaced apart in a second direction and extending along a first direction, are connected to the sides of the truss assembly 1 and the fixed assemblies 3. The truss assembly 1 is horizontally connected to the fixed assemblies 3 via the purlins 2. The specific construction process is as follows: First, one end of each purlin 2 is connected (or welded) to the side of the truss assembly 1 relative to the first direction. Then, the truss assembly 1 is hoisted to a specified height, keeping the crossbeam assembly horizontal, and the other end of each purlin 2 is aligned with the side of the fixed assemblies 3 relative to the first direction. Next, the purlins 2 are connected (or welded) to the fixed assemblies 3, thus achieving the connection between the truss assembly 1 and the fixed assemblies 3. Since the truss assembly 1 does not need to be mounted on the top surface of the fixed assemblies 3 for docking during this process, the pre-arching has minimal impact on the construction of the roof truss. In summary, the construction difficulty and construction period of this utility model roof truss are low, effectively ensuring the connection accuracy between the truss assembly 1 and the fixed assemblies 3, thereby ensuring the stability of the roof truss structure.

[0027] Furthermore, the purlin 2 includes a web 22 and two wing plates 21, the two wing plates 21 being spaced apart in the vertical direction, the web 22 being disposed between the two wing plates 21 and connected to the two wing plates 21.

[0028] Among them, the web plate 22 and the upper and lower flanges 21 form an "I" shaped cross-sectional structure, so that the purlin 2 has strong bending and shear strength, which can effectively bear the horizontal force and part of the vertical load transmitted by the truss assembly 1, and prevent the purlin 2 from bending or shearing due to excessive force.

[0029] Furthermore, the purlin 2 also includes two side plates 23, which are respectively disposed on both sides of the web plate 22 along the second direction and located between the two wing plates 21. The side plates 23 are connected to the two wing plates 21.

[0030] Among them, the side plate 23, the web plate 22 and the double wing plate 21 form a closed cross-sectional structure to further enhance the strength of the purlin 2.

[0031] Furthermore, it also includes multiple connecting blocks 4 that correspond one-to-one with the purlins 2. The connecting blocks 4 are located on the side of the fixing component 3 relative to the first direction. The side of the connecting block 4 facing the purlin 2 is provided with a connecting groove 41. The connecting groove 41 penetrates the top and bottom surfaces of the connecting block 4 in the vertical direction. The web plate 22 is inserted into the connecting groove 41 and connected to the connecting block 4.

[0032] The vertical through-hole design of the connecting groove 41 can limit the web plate 22 of the purlin 2. During construction, the web plate 22 only needs to be inserted into the groove to complete the initial positioning, which greatly improves the installation efficiency. Moreover, the web plate 22 can make surface contact with the connecting groove 41, and the stress distribution after connection is more uniform.

[0033] Furthermore, it also includes multiple embedded parts 5 that correspond one-to-one with the purlin 2. The embedded parts 5 are provided on the side of the fixing component 3 relative to the first direction. The side of the embedded part 5 facing the purlin 2 is provided with a connecting plane 51, and the purlin 2 is connected to the connecting plane 51.

[0034] Among them, the connecting plane 51 provides a flat and uniform connection benchmark for the purlin 2, which can effectively offset the construction errors on the side of the steel beam 32 or the beam and column 31, and avoid connection gaps or uneven stress caused by uneven contact surfaces.

[0035] Furthermore, the connecting block 4 can be located on the connecting plane 51.

[0036] In some embodiments, the web 22 is inserted into and connected to the connecting groove 41.

[0037] In other embodiments, the wing plate 21 and the side plate 23 are connected to the connecting plane 51, and the web plate 22 is inserted into and connected to the connecting groove 41.

[0038] Furthermore, it also includes a plurality of first tie rods 6 extending along the second direction, each of the purlins 2 having a through hole extending along the second direction, the first tie rods 6 passing through the through holes of the plurality of purlins 2 and connected to the through holes.

[0039] The first tie rod 6 connects multiple spaced purlins 2 together to prevent individual purlins 2 from deforming due to uneven stress.

[0040] Furthermore, the purlin 2 is provided with a plurality of through holes spaced apart along the first direction, and each through hole on the purlin 2 corresponds to the first tie rod 6.

[0041] The arrangement of multiple first tie rods 6 at intervals along the first direction can make the purlin 2 more evenly stressed and reduce the load on a single tie rod.

[0042] Furthermore, it also includes a plurality of second tie rods 7 and a plurality of third tie rods 8 extending horizontally. Two second tie rods 7 are respectively disposed on both sides of the first tie rod 6 closest to the fixing component 3 along the first direction. One end of the second tie rod 7 is connected to one end of the first tie rod 6 and the other end is connected to the side of the fixing component 3 relative to the first direction. Two third tie rods 8 are respectively disposed on both sides of the first tie rod 6 closest to the truss component 1 along the first direction. One end of the third tie rod 8 is connected to one end of the first tie rod 6 and the other end is connected to the side of the truss component 1 relative to the first direction.

[0043] The fixing component 3 is connected to and pulls the two ends of the closest first tie rod 6 through two second tie rods 7, and the truss component 1 is connected to and pulls the two ends of the closest first tie rod 6 through two third tie rods 8 to offset part of the pressure on the purlin 2.

[0044] Furthermore, the truss assembly 1 includes a first truss 11 extending along a plurality of first directions and a plurality of second trusses 12 extending along a second direction. The plurality of first trusses 11 are spaced apart along the second direction, and the plurality of second trusses 12 are spaced apart along the first direction. Any first truss 11 connects to each of the second trusses 12, and any second truss 12 connects to each of the first trusses 11. One end of the purlin 2 is connected to the side of the second truss 12 opposite to the first direction.

[0045] Multiple first trusses 11 and multiple second trusses 12 are connected to form a grid-like overall truss to ensure its overall rigidity and load-bearing capacity; in addition, the first trusses 11 can be set on the bottom surface of the second trusses 12.

[0046] Furthermore, the fixing component 3 includes a plurality of vertically arranged beams 31 and a plurality of horizontal beams 32 extending along a second direction. The plurality of beams 31 are spaced apart along the second direction, and the horizontal beams 32 are provided between two adjacent beams 31. The two ends of the horizontal beams 32 are connected to the sides of the two adjacent beams 31 relative to the second direction. One end of a portion of the purlins 2 is connected to the side of the beams 31 relative to the first direction, and the other end of the purlins 2 is connected to the side of the horizontal beams 32 relative to the first direction.

[0047] Among them, the combined structure of beam-column 31 and crossbeam 32 has high strength and stiffness, and can stably bear the load transmitted by purlin 2; in addition, beam-column 31 can be reinforced concrete column, and crossbeam 32 can be concrete beam.

[0048] Furthermore, the second tie rod 7 is connected to the beam column 31, and the third tie rod 8 is connected to the second truss 12.

[0049] Furthermore, fixed setting and fixed connection refer to the fixed relative positional relationship of two components, including but not limited to fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit ​​connection.

[0050] Furthermore, the connectors include, but are not limited to, fasteners, straps, ropes, pneumatic connectors, hydraulic connectors, flanges, Velcro, and buttons.

[0051] In summary, the present invention provides a roof truss, the technical effects of which are as follows: In the roof truss of this utility model, the truss assembly 1 is located between two fixed assemblies 3. Multiple purlins 2, spaced apart in a second direction and extending along a first direction, are connected to the sides of the truss assembly 1 and the fixed assemblies 3. The truss assembly 1 is horizontally connected to the fixed assemblies 3 via the purlins 2. The specific construction process is as follows: First, one end of each purlin 2 is connected (or welded) to the side of the truss assembly 1 relative to the first direction. Then, the truss assembly 1 is hoisted to a specified height, keeping the crossbeam assembly horizontal, and the other end of each purlin 2 is aligned with the side of the fixed assemblies 3 relative to the first direction. Next, the purlins 2 are connected (or welded) to the fixed assemblies 3, thus achieving the connection between the truss assembly 1 and the fixed assemblies 3. Since the truss assembly 1 does not need to be mounted on the top surface of the fixed assemblies 3 for docking during this process, the pre-cambering has minimal impact on the construction of the roof truss. In summary, the roof truss of this utility model has lower construction difficulty and a shorter construction period, effectively ensuring the connection accuracy between the truss assembly 1 and the fixed assemblies 3, thereby ensuring the stability of the roof truss structure.
