Description

Technical Field

[0001] This invention relates to the field of roof frame engineering, and more particularly to a self-balancing membrane roof frame system suitable for three-dimensional grid roofs. Background Technology

[0002] Membrane roofs are a relatively novel design form in modern architecture. Their main characteristic lies in the use of high-performance membrane materials as the main roof structure. These membrane materials typically possess lightweight, flexibility, high strength, and good light transmission. This roof design, with its unique shape and excellent performance, is widely used in stadiums, exhibition centers, public facilities, and other large-scale building projects. As a new type of roofing system, membrane roofing systems offer advantages such as a light and airy effect and good transparency, leading to their increasing application in recent years. The main components of a membrane roofing system include the roof membrane and the supporting frame. The supporting frame can be a rigid frame composed of steel pipes or a flexible frame composed of cables. However, rigid frames are often quite bulky, which conflicts with the light and airy effect of membrane roofing systems; therefore, designers often prefer flexible frames. For flexible frames, the cables need to be pre-tensioned to obtain sufficient supporting stiffness; furthermore, the cable tension changes with external loads such as wind and snow. Therefore, membrane roofing systems using flexible frames introduce additional loads to the main roof structure, reducing the safety of the roof structure.

[0003] Three-dimensional mesh spatial grid structures offer excellent structural performance and aesthetic appeal, making them widely used in large public buildings such as stadiums and exhibition halls. In practice, a common challenge in applying membrane roofing systems to three-dimensional mesh roofs is minimizing the additional loads introduced by the roofing system onto the main roof structure. Therefore, proposing a self-balancing membrane roof frame system applicable to three-dimensional mesh roofs has significant practical engineering implications. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a self-balancing membrane roof frame system suitable for three-dimensional grid roofs to solve the problems mentioned in the background art or achieve better technical effects.

[0005] To solve the aforementioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention. This invention discloses a self-balancing membrane roof frame system suitable for three-dimensional grid roofs, including purlins, planar bidirectional ear plates, cables, spatial three-dimensional ear plates, and struts. The purlins and planar bidirectional ear plates are welded together to form a triangle located on the outermost periphery of the self-balancing roof system frame to balance the horizontal force generated by the tension of the roof system and to connect with the main roof structure. The spatial three-dimensional ear plates are welded integrally with the struts and located at the center of the self-balancing roof system frame to balance the vertical force generated by the tension of the roof system. The two ends of the cables are respectively connected to the planar bidirectional ear plates and the spatial three-dimensional ear plates in the form of pins to anchor the roof membrane.

[0006] Furthermore, the number of purlins and planar bidirectional lugs is three. The three planar bidirectional lugs are vertically arranged at the three corner points of the triangle, with their directions coinciding with the angle bisectors of the corner points; the three purlins are welded to the sides of the three planar bidirectional lugs in pairs to form the three sides of the triangle.

[0007] Furthermore, the planar bidirectional ear plate is made of steel plate, and the purlin is made of square or rectangular steel pipe.

[0008] Furthermore, the number of the spatial three-way lugs and the number of the struts are two and one, respectively. The two spatial three-way lugs are respectively installed on the top and bottom of the strut by means of insert welding.

[0009] Furthermore, the spatial three-way ear plate is made of steel plate, and its three directions are the same as the directions of the planar two-way ear plate located at the three corner points of the triangle.

[0010] Furthermore, the support rod is a round steel tube. Slots are cut at the positions where spatial three-way ear plates are located at the top and bottom of the support rod, and sealing plates are installed at both ends.

[0011] Furthermore, there are a total of six cables, divided into three groups of two cables each.

[0012] Furthermore, one end of each of the three sets of cables is connected to one of the three planar bidirectional ear plates located at the corners of the triangle, and the other end is connected to the spatial triaxial ear plate located at the center. Each set of cables consists of two cables, an upper cable and a lower cable. The two ends of the upper cable are connected by pins to the upper pin holes of the planar bidirectional ear plate and the spatial triaxial ear plate located at the top of the strut, respectively. The two ends of the lower cable are connected by pins to the lower pin holes of the planar bidirectional ear plate and the spatial triaxial ear plate located at the bottom of the strut, respectively.

[0013] Compared with the prior art, the present invention can achieve at least the following beneficial effects:

[0014] (1) The present invention is a self-balancing system as a whole, which will not introduce additional loads to the main roof structure, thus ensuring the safety of the main roof structure;

[0015] (2) The cables and vertically arranged struts of the present invention are relatively slender, which can present a light and transparent architectural effect, and the light transmission effect is better, making the building more beautiful and practical;

[0016] (3) The multiple self-balancing membrane roof system frames of the present invention can be freely combined, and are suitable for various roof system design situations;

[0017] (4) The purlins and cables of the present invention form a closed plane, which facilitates the rooting of the roofing membrane.

[0018] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the specification or be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained from the content specifically pointed out in the text and accompanying drawings. Attached Figure Description
