Description

Technical Field

[0001] The invention relates to the field of roof frame engineering, and in particular to a self-balancing membrane roof frame system suitable for a three-way grid roof. Background Art

[0002] Membrane structure roof is a relatively new design form in the field of modern architecture. Its main feature is the use of high-performance membrane materials as the main structural materials. These membrane materials are usually light, flexible, high-strength and good light transmittance. This roof design is widely used in stadiums, exhibition centers, public facilities and other large-scale construction projects with its unique shape and excellent performance. As a new type of roof system, the membrane roof system has the advantages of light effect and good permeability, and its application has become more and more in recent years. The main part of the membrane roof system includes the roof membrane and the supporting skeleton, in which the supporting skeleton is a rigid skeleton composed of steel pipes or a flexible skeleton composed of cables. The rigid skeleton is often relatively large, which conflicts with the light and transparent effect of the membrane roof system, so designers often prefer flexible skeletons. For the flexible skeleton, the cable needs to be pre-tensioned to obtain sufficient support stiffness; in addition, the cable force of the cable will also change with the action of external loads such as wind and snow. Therefore, the membrane roof system with a flexible skeleton will introduce additional loads to the main roof structure and reduce the safety of the roof structure.

[0003] The three-dimensional grid structure has good mechanical performance and beautiful appearance, and is widely used in large public buildings such as gymnasiums and exhibition halls. In practice, the problem often faced by the application of membrane roofing systems in three-dimensional grid roofs is how to reduce the additional load introduced by the roofing system to the main structure. Therefore, a self-balancing membrane roof system skeleton that can be applied to three-dimensional grid roofs is proposed, which has significant engineering practical significance. Summary of the invention

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

[0005] In order to solve the above technical problems, the inventors have obtained the technical solution of the present invention through practice and summary. The present invention discloses a self-balancing membrane roof skeleton system suitable for three-way grid roof, including purlins, plane two-way ear plates, cables, spatial three-way ear plates, and struts. The purlins and the plane two-way ear plates are welded to form a triangle and arranged at the outermost periphery of the self-balancing roof system skeleton to balance the horizontal force generated by the tensioning of the roof system and connected to the main structure; the spatial three-way ear plates and the struts are welded as one and arranged at the center of the self-balancing roof system skeleton to balance the vertical force generated by the tensioning of the roof system; the two ends of the cable are respectively connected to the plane two-way ear plates and the spatial three-way ear plates in the form of pins so that the roof membrane can take root.

[0006] Furthermore, the number of the purlins and the planar two-way ear plates are three. The three planar two-way ear plates are respectively arranged vertically at the three corner points of the triangle, and their directions coincide with the angular bisectors of the corner points; the three purlins are respectively welded to the sides of the three planar two-way ear plates in pairs, forming 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 three-dimensional space ear plates and the number of the support rod are two and one respectively. The two three-dimensional space ear plates are respectively installed on the top and bottom of the support rod in the form of plug-in welding.

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

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

[0011] Furthermore, the cables are six in total and divided into three groups, with two cables in each group.

[0012] Furthermore, one end of the three groups of cables are respectively connected to the three planar two-way ear plates at the corner points of the triangle, and the other ends are all connected to the spatial three-way ear plate at the center. Each group of cables consists of two cables, upper and lower, wherein the two ends of the cables located at the upper part are respectively connected to the upper pin holes of the planar two-way ear plates and the spatial three-way ear plates at the top of the struts in the form of pin shafts, and the two ends of the cables located at the lower part are respectively connected to the lower pin holes of the planar two-way ear plates and the spatial three-way ear plates at the bottom of the struts in the form of pin shafts.

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

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

[0015] (2) The cables and vertically arranged support rods 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 applicable to various roof system design situations;

[0017] (4) The purlins and cables of the present invention form a closed plane, which is convenient for the roof membrane to take root.

[0018] In the present invention, the above-mentioned technical solutions can also be combined with each other to achieve more preferred combination solutions. Other features and advantages of the present invention will be described in the following content, and some advantages can be obvious from the description or understood by practicing the present invention.
