Description

Technical Field

[0001] The utility model relates to the technical field of membrane structure buildings, in particular to a waterproof node of a membrane structure. Background Art

[0002] Membrane structure buildings belong to architectural landscape engineering design. They achieve functions such as sunshade and rain protection by covering the supporting system with membrane materials. They have the advantage that their weight is only one thirtieth of that of traditional buildings. They fundamentally overcome the difficulties encountered when traditional structures are implemented in large-span (unsupported) buildings, and can create huge unobstructed visual space. They are suitable for large stadiums, entrance corridors, sketches, public leisure and entertainment plazas, exhibition venues, shopping malls and other places.

[0003] In the construction of existing membrane structure buildings, since the membrane material on the supporting system is covered on the supporting system, after the membrane material is covered, joints (gaps) will inevitably appear between the membrane material and the supporting system. Leakage is most likely to occur at these joints, and waterproof nodes need to be designed to effectively prevent rainwater from penetrating into the building structure. For this purpose, a waterproof node of a membrane structure is proposed. Utility Model Content

[0004] Based on the above description, the utility model provides a waterproof node of a membrane structure, which solves the technical problem that the joints between the membrane material and the supporting system in the existing membrane structure buildings are prone to leakage.

[0007] The top surface structure includes a membrane material body and assembly parts, wherein the number of the assembly parts is twice that of the membrane material body and can be detachably arranged in the corresponding limiting areas. The membrane material body is arranged between two sets of adjacent node frames and adheres to the top surface of the beam.

[0011] Furthermore, an arrow-shaped rain shield edge is provided on the node frame, and a rain shield area is formed between the rain shield edge and the node frame, so that the bolts can pass through the rain shield edge to protect against rain.

[0012] Furthermore, the number of the support frames is three groups, the number of the membrane material bodies is two groups, and the number of the assembly parts is four groups.

[0013] Furthermore, the cross-sections of the folded area of ​​the film material and the assembly part are both circular.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] like Figure 1 As shown, a waterproof node of a membrane structure in this embodiment includes a supporting structure 1 and a top surface structure 2, wherein the supporting structure 1 is mainly used to support the top surface structure 2, and cooperates with the top surface structure 2 to play a waterproof role, ensuring that the membrane structure building will not have rainwater leakage.

[0027] First, if Figure 1-4 As shown, the support structure 1 includes at least two groups of support frames 11, and preferably the number of support frames 11 is three groups. At this time, the number of top surface structures 2 is two groups, and one group of top surface structures 2 is used to be installed between any two adjacent groups of support frames 11, and a crossbeam 12 is welded between any two adjacent groups of support frames 11, and the crossbeam 12 is used to provide auxiliary support to the top surface structure 2 to prevent the top surface structure 2 from being deformed, thereby avoiding water accumulation in the top surface structure 2, and a node frame 13 is welded on the support frame 11, and a positioning cavity 14 is opened on both sides of the node frame 13, and the positioning cavity 14 is divided into a membrane material folding area 15 and a limiting area 16.

[0028] It should be noted that if Figure 4 As shown, the cross section of the film material folding area 15 is preferably circular, while the cross section of the limiting area 16 is preferably arc-shaped, and the film material folding area 15 and the limiting area 16 are arranged concentrically.

[0029] In addition, if Figure 3As shown, the top surface structure 2 includes a membrane material body 21 and assembly parts 22, wherein the number of assembly parts 22 is twice that of the membrane material body 21, that is, when the number of the membrane material body 21 is two groups, the number of the assembly parts 22 is four groups, and the assembly parts 22 are detachably arranged in the corresponding limiting area 16, and the membrane material body 21 is specifically fixedly arranged between two groups of adjacent node frames 13, and is attached to the top surface of the crossbeam 12, so that the crossbeam 12 can support the membrane material body 21, thereby preventing or reducing the deformation of the membrane material body 21, and avoiding the situation where, for example, local potholes and water accumulation occur in the membrane material body 21. The left and right sides of the membrane material body 21 are folded along the corresponding membrane folding area 15, so that after the assembly parts 22 are built into the limiting area 16, the two sides of the membrane material body 21 will be hidden, and the two sides of the membrane material body 21 will be squeezed, so that rainwater is not easy to pass through between the membrane material body 21 and the node frame 13, ensuring that the waterproof node of the membrane structure will not seep.

[0030] It should be noted that the membrane body 21 is, for example, an ETFE membrane, which is a prior art and will not be described in detail herein. When the cross section of the membrane folding area 15 is preferably circular, the cross section of the assembly part 22 is also preferably circular.

[0031] To further explain, the number of beams 12 is no less than two groups, and the beams 12 are linearly distributed at equal distances from front to back. The beams 12 are used to support the membrane material body 21, and the cross-section of the beams 12 is arc-shaped, and reinforcing ribs 17 are welded between any two adjacent groups of beams 12. In this way, the tightness of the connection between the beams 12 can be strengthened to ensure the structural strength, and the reinforcing ribs 17 can also support the membrane material body 21.

[0032] Since there are various detachable structures between the assembly part 22 and the node frame 13 , two detachable structures between the assembly part 22 and the node frame 13 are provided here for easy understanding.

[0033] In one embodiment, if Figure 5 As shown, the outer side of the assembly part 22 is integrally connected with a spring piece 23 , which abuts against the outer wall of the node frame 13 . Since the assembly part 22 is located in the limiting area 16 , the assembly part 22 can be clamped in the limiting area 16 through the spring piece 23 .

[0034] It should be noted that the spring piece 23 is made of thermoplastic plastics, for example, polyethylene, polyvinyl chloride, polypropylene, polystyrene, acrylonitrile-butadiene-styrene and other general plastics, or other thermoplastic materials with high elasticity.

[0035] In another embodiment, if Figure 3 As shown, the node frame 13 is provided with bolts 24 threadedly connected to the assembly part 22 .

[0036] To prevent the bolt 24 from rusting, further, as Figure 3 As shown, an arrow-shaped rain shield edge 3 is welded on the node frame 13, and a rain shield area is formed between the rain shield edge 3 and the node frame 13, so that the bolts 24 can pass through the rain shield edge 3 to protect against rain.

[0037] Working principle:

[0038] By folding both sides of the membrane body 21 and hiding them in the membrane folding area 15, when the membrane body 21 is not damaged, rainwater can only leak through the tiny gap between the membrane body 21 and the node frame 13, and the assembly parts 22 are used to further seal and press, so that rainwater is not easy to pass through between the membrane body 21 and the node frame 13, ensuring that the membrane structure building will not leak.

[0039] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
