Description

Technical Field

[0001] The utility model relates to the technical field of membrane pulling nodes, in particular to a membrane pulling node for a rigid membrane valley. Background Art

[0002] Gutters are mostly used for drainage on membrane structure sheds. Due to the installation of gutters, water on the shed can gather in the gutters and be quickly discharged. The gutters are groove structures between membrane structures. Since grooves are opened there, the grooves formed by the membranes at the lower places can also be called membrane valleys. Generally, when the forces on both sides of the membrane are consistent, profiles are usually used for fixing. However, when the tension of the membranes on both sides is inconsistent, the use of profiles will cause uneven forces on the profiles, leading to damage to the membrane fixing nodes.

[0003] The patent publication number CN220434070U was retrieved, and the patent name is a public material for a membrane pressing node for a membrane structure shed. It specifically discloses a membrane pressing node for a membrane structure shed, including a square tube for forming a membrane structure steel frame, and an adapter arranged on the square tube, a gutter for drainage is formed between the adapters, and also includes: a supporting device, the supporting device includes a fixing frame connected to the adapter, the fixing frame is connected to a membrane supporting plate, the membrane supporting plate is connected to an aluminum profile, and a membrane hanging profile is placed on the upper end surface of the aluminum profile; a membrane structure, the membrane structure includes a curling edge inserted into the membrane hanging profile, the curling edge is connected to the membrane material; a fixing device, the fixing device includes an undercut groove arranged in the middle position of the aluminum profile, an undercut column is installed inside the undercut groove, the undercut column is connected to a cover body, the lower end of the aluminum profile is connected to a fixing bolt, and is connected to the membrane supporting plate by the fixing bolt, the aluminum profile is a through-length structure, and the membrane supporting plate is welded and fixed to the fixing frame.

[0004] By analyzing the above public materials, it can be known that the membrane pressing node of this structure can be used when the membrane tension on both sides is consistent or not much different. If the tension difference on both sides is too large, the membrane pressing node of this structure will cause damage to the profile and membrane material. Utility Model Content

[0009] a main film disposed between the pressure plates;

[0010] A heat-sealing reinforcement film is provided on the upper end surface of the main film and is used for heat-sealing and connecting the two main films;

[0015] Furthermore, there are two angle steels with a space in between for placing the pressure plate and the main membrane.

[0016] The beneficial effects of the above technical solution of the utility model are as follows:

[0025] In this embodiment, the steel pipe 1 is the main steel pipe 1 on the steel structure, which is used to form a steel structure frame, and the steel pipe 1 at this location is the position of the membrane valley. A stiffening plate 2 is provided on the steel pipe 1, and a base 3 is provided at the upper end of the stiffening plate 2. The base 3 is a plate-like structure, forming a T-shape with the stiffening plate 2. Two angle steels 5 are provided on the upper end face of the base 3, and a pressure plate 6 is clamped between the angle steels 5. The main membrane 8 is clamped between the pressure plates 6. In order to adapt to different membrane tensions, the structure of the angle steel 5 is adopted, which is more firm. In addition, a heat-sealed reinforcing membrane 9 is provided on the main membrane 8 to further stabilize the change in tension. Example

[0026] The main film 8 is a two-piece structure, and both are squeezed and fixed by the pressing plate 6. A film curling edge 10 is provided at the lower end of the main film 8, and a winding core 11 is provided inside the film curling edge 10. The winding core 11 is provided below the pressing plate 6.

[0027] Different from the above embodiment, in this embodiment, the main membrane 8 is a two-piece structure, and a membrane pressing node is formed at the steel pipe 1. In order to protect the membrane material, a pressure plate 6 is used for clamping. In addition, in order to prevent the main membrane 8 from detaching, a membrane curling edge 10 is provided at the edge of the main membrane 8, and a winding core 11 is provided inside the membrane curling edge 10, and then fixed by the pressure plate 6. Example

[0028] The fixing bolts B7 pass through the pressing plate 6, the main membrane 8 and the angle steel 5. The main membrane 8 is V-shaped to form a membrane valley.

[0029] Different from the above embodiment, in this embodiment, the fixing bolt B7 is used to clamp the main membrane 8 between the pressure plates 6 and needs to pass through the two pressure plates 6 , the two main membranes 8 and the two angle steels 5 . Example

[0030] The heat-sealed reinforcing film 9 is fixed to the upper end surfaces of the two main films 8 by heat sealing, forming a star-shaped connection between the two main films 8 and the pressing plate 6 .

[0031] Different from the above embodiment, in this embodiment, the heat-sealed reinforcement membrane 9 can not only prevent rainwater from entering the steel pipe 1 through the gap, but also further strengthen the connection tightness between the two main membranes 8. Example

[0032] There are two angle steels 5 with a space between them for placing the pressing plate 6 and the main membrane 8 .

[0033] Different from the above embodiment, in this embodiment, in order to improve stability, the number of angle steels 5 is two, and a space is reserved in the middle, and the space is used for the placement of the pressure plate 6 and the main membrane 8.

[0034] The working method (or working principle) of this utility model:

[0035] When this technology is working, at the membrane pressing node, when the tensions on the two membranes are the same or the difference is very small, they can be fixed by profiles. However, when the tensions on the membranes on both sides are inconsistent or even differ greatly, a more stable membrane pressing node is required. A simple profile structure cannot meet the needs because when the tension is offset, the profile will be stressed to one side, causing the profile to break. Therefore, in this technology, two angle steels 5 are set on the base 3, and a gap is left between the angle steels 5. Two pressure plates 6 are set within the gap. The outer sides of the pressure plates 6 directly contact the angle steels 5, and the inner sides of the pressure plates 6 respectively contact and connect the two main membranes 8. The two main membranes 8 face two directions at the top and form a membrane valley there. In addition, in order to protect the main membrane 8, the upper end of the pressure plate 6 is designed to be an arc-shaped top edge 12. 12 In order to balance the tension and prevent rainwater, a heat-sealed reinforcement membrane 9 is set at the upper end of the main membrane 8.

[0036] In the present invention, unless otherwise clearly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly specified and limited, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0037] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
