Description

[0050] As Figure 1 Figure 7 The embodiment provides a framework membrane shed structure, which comprises a roof structure 1, a support structure 4 and a membrane structure.

[0051] The roof structure 1 comprises a plurality of main trusses 2 and connecting support members 3. The main trusses 2 are arranged in an arc shape, with the opening downward. Adjacent main trusses 2 are arranged in parallel and at equal intervals. As an alternative embodiment, the adjacent main trusses 2 can also be arranged at non-uniform intervals. The connecting support members 3 can connect adjacent main trusses 2 and are arranged to protrude upward. A plurality of connecting support members 3 between adjacent main trusses 2 are arranged in an arc shape and extend in the same direction as the main trusses 2. In the embodiment, the protruding height of the connecting support members 3 is higher than the horizontal height of the main trusses 2, and the curvature of the arrangement of the connecting support members 3 is the same as that of the main trusses 2. As an alternative embodiment, the curvature of the arrangement of the connecting support members 3 between adjacent main trusses 2 can also be different from that of the main trusses 2, such as being provided with a concave-convex structure with varying curvature.

[0052] The support structure 4 is arranged at the bottom side of the roof structure 1 and is connected to the main trusses 2. The specific structure of the support structure 4 is not limited, and in the embodiment, the support structure 4 is arranged in the same shape as the main trusses 2 and is fixedly connected to the main trusses 2, so as to support the roof structure 1. In addition, the roof is arranged in an arc surface, and on both sides along the length direction, frame support structures or portal structures can be arranged according to actual needs.

[0053] The membrane structure at least covers the outer side of the roof structure 1 and is arranged in close contact with the main trusses 2 and the connecting support members 3. In the embodiment, the membrane structure completely covers the outer side of the roof structure 1 and the support structure 4. As an alternative embodiment, the membrane structure can only cover the outer side of the roof structure 1.

[0054] ​The continuous arc-shaped wave-shaped roof structure 1 is formed by the arc-shaped and parallel spaced main truss 2 and the connecting support 3 connecting adjacent main trusses 2 and arranged in an arc shape and protruding upward.

[0055] The main truss 2 comprises a truss chord structure and a triangular support structure 13.

[0056] The truss chord structure is arranged in a circular arc shape and connected with the support structure 4, and comprises a truss top chord 11 and two truss bottom chords 12. The two truss bottom chords 12 are arranged at the same horizontal height and are parallel to the underside of the truss top chord 11 and extend in the same direction as the truss top chord 11. In this embodiment, adjacent truss top chords 11 and truss bottom chords 12, as well as adjacent truss bottom chords 12, are arranged at equal distances and form an equilateral triangle in the vertical cross-section. This arrangement can more evenly distribute the load of the main truss 2 and improve the load-bearing capacity of the main truss 2. As an alternative embodiment, adjacent truss top chords 11 and truss bottom chords 12, as well as adjacent truss bottom chords 12, can be arranged at unequal distances, such as an isosceles triangle in the vertical cross-section perpendicular to the extension direction of the truss chord, or the distances of the three vertices are not equal.

[0057] The triangular support structure 13 comprises three support chord structures and is arranged inside the truss chord structure. The top end of the triangular support structure 13 is connected with the truss top chord 11 in the height direction, and the bottom edge is connected with the two truss bottom chords 12, respectively.

[0058] By arranging the triangular support structure 13 inside the truss chord structure extending in a triangular trajectory and connecting the truss top chord 11 and the truss bottom chord 12, the structural stability of the main truss 2 is improved. At the same time, the truss bottom chords 12 are arranged at the same height and on the underside of the truss bottom chords 12. This arrangement facilitates the bearing of loads in the vertical direction and improves the load-bearing effect on rain and snow loads.

[0059] In the embodiment, the triangular support structures 13 are uniformly arranged along the extension direction of the truss top chord 11 and the truss bottom chord 12. Such arrangement makes the structural strength of the main truss 2 more uniform. As an alternative embodiment, the triangular support structures 13 can be non-uniformly arranged along the extension direction of the truss top chord 11 and the truss bottom chord 12.

[0060] In the embodiment, the adjacent triangular support structures 13 are arranged along the top end or the bottom edge, specifically, share the same top point or share the same bottom edge. Such arrangement makes the triangular support structures 13 more closely arranged and higher in material utilization.

[0061] The adjacent triangular support structures 13 arranged along the top end are connected at the positions of at least two oppositely arranged top points on the bottom edge. In the embodiment, one reinforcing chord 14 is arranged between two adjacent triangular support structures 13 arranged along the top end, and the ends of different reinforcing chords 14 are connected. As an alternative embodiment, two reinforcing chords 14 can be arranged between two adjacent triangular support structures 13 arranged along the top end. By adding the reinforcing chords 14, the stability of the triangular support structures 13 is further improved, the structural strength of the main truss 2 is ensured, and the load bearing capacity is improved.

[0062] The main truss 2 further comprises a tension structure 15 arranged on the lower side of the truss chord structure and fixedly connected with at least the truss bottom chord 12. In the embodiment, the tension structure 15 is fixedly connected with the truss bottom chord 12, the truss top chord 11 and the triangular support structures 13. As an alternative embodiment, the tension structure 15 can be fixedly connected with only the truss bottom chord 12. By arranging the tension structure 15, tension force is provided for the lower side of the main truss 2 arranged in an arc shape, the top side load of the main truss 2 is balanced, and the stability of the main truss 2 is improved.

[0063] The tension structure 15 comprises a tension chord 151, a connecting chord 152 and a fixed chord 153.

[0064] The tension chord 151 is arranged on the lower side of the truss bottom chord 12 and fixedly connected with the bottom edge of the triangular support structure 13 arranged at the middle of the two truss bottom chords 12 at the end thereof; the connecting chord 152 is connected with the tension chord 151 at one end and fixedly connected with the end of the bottom edge of the triangular support structure 13 at the other end; and the fixed chord 153 is arranged on the triangular support structure 13 and fixedly connected with the end of the tension chord 151 and the triangular support structure 13.

[0065] In addition, the top end of the middle part of the main truss 2 further protrudes a ventilation skylight frame 5 which penetrates the membrane structure and is connected with the ventilation skylight frame 5 on the adjacent main truss 2. As an alternative embodiment, the ventilation skylight frame 5 can not be arranged.

[0066] The connecting support 3 comprises connecting trusses 31 and arc-shaped support rods 32. The connecting trusses 31 are arranged in an arc shape and protrude upward, are arranged in the same shape as the main trusses 2, and correspond to the truss top chords 11 and the truss bottom chords 12 of the main trusses 2 respectively; the arc-shaped support rods 32 are arranged alternately and spaced apart in the same direction as the connecting trusses 31, and the arc-shaped support rods 32 connect the truss top chords 11 of the adjacent main trusses 2.

[0067] By arranging the connecting trusses 31 in the same shape as the main trusses 2, the triangular support structure 13 is arranged in the connecting trusses 31 and the connecting trusses 31 connect the truss top chords 11 and the truss bottom chords 12 respectively, which can stabilize the structure of the adjacent main trusses 2, ensure the structural strength of the whole roof structure 1, and cooperate with the arrangement of the arc-shaped support rods 32 to support the membrane structure and be arranged alternately and spaced apart from the connecting trusses 31, thereby ensuring the uniformity of the support of the membrane structure.

[0068] The connecting support 3 further comprises arc-shaped tie rods 33 arranged along the top sides of the middle portions of the connecting trusses 31 and the arc-shaped support rods 32 and having the same curvature as the main trusses 2. By arranging the arc-shaped tie rods 33 in the middle portions of the connecting trusses 31 and the arc-shaped support rods 32, the spacing between the connecting trusses 31 and the arc-shaped support rods 32 and the stability of the structure of the connecting trusses 31 and the arc-shaped support rods 32 are further ensured, thereby avoiding problems such as twisting, shaking or deviation under external force.

[0069] In the embodiment, the connection mode of the main trusses 2 and the connecting support 3 is the penetrating welding. By penetrating welding the two ends of the connecting support 3 to the main trusses 2, the construction method is simple, the stress structure is stable, the membrane structure and the snow load can be effectively borne, and as a convertible embodiment, the connection nodes of other structures on the framework membrane shed structure can also be fixedly connected by penetrating welding.

[0070] Obviously, the above embodiments are only examples for clearly illustrating the present application and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and cannot be exhausted.
