Description

Technical Field

[0001] The utility model relates to the technical field of PTFE membrane construction, in particular to a PTFE membrane tensioning node. Background Art

[0002] With the rapid development of the domestic construction market, more projects with novel shapes, high spaces and complex structures have sprung up like mushrooms after a rain. While meeting the shape requirements, relatively new materials with higher construction requirements are often used, and PTFE membrane is one of them.

[0003] PTFE is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. It has the characteristics of excellent light transmittance, thin thickness, high strength, and beautiful effect after construction. It can be used as building roofs and walls that need light transmission. At the same time, its film thickness is relatively thin, and it is also easy to be damaged, and has high requirements for construction quality and finished product protection.

[0004] CN115404989A discloses a connection structure between a PTFE membrane and a keel node and a construction method thereof, wherein the PTFE membrane is wrapped around a first keel, a second keel is passed through an opening, and then a connecting piece is installed and connected to a positioning plate. The PTFE membrane is tensioned by moving and adjusting the connecting piece in a direction away from the second keel.

[0005] CN216075772U discloses a PTFE membrane and glass curtain wall connection structure, in which a tensioning rope is moved into a cavity, a first PTFE membrane passes through an opening, a connecting rod is fixed to the glass curtain wall through a connecting assembly, and the first PTFE membrane is fixed. The opening is located on a side close to the first PTFE membrane, and the first PTFE membrane at the opening does not abut against the side wall of the opening. The first PTFE membrane pulls the tensioning rope to abut against the side wall of the connecting rod. The tensioning force of the first PTFE membrane is mainly borne by the tensioning rope and the side wall of the connecting rod, thereby reducing the possibility of damage to the first PTFE membrane at the connection. The second PTFE membrane covers the connecting rod, and the second PTFE membrane is fixed to the glass curtain wall through a fixing assembly. The second PTFE membrane further strengthens the connection between the first PTFE membrane and the curtain wall.

[0006] However, the current PTFE membrane tensioning node cannot achieve separate membrane installation. Therefore, a PTFE membrane tensioning node that can achieve separate membrane installation is needed. Utility Model Content

[0007] In view of the above problems, the utility model provides a PTFE membrane tensioning node, which adopts a membrane-separated installation method to achieve the tensioning of the PTFE membrane while meeting the high-standard installation of the PTFE membrane.

[0008] Specifically, the utility model provides a PTFE membrane tensioning node, comprising:

[0009] PTFE membrane;

[0010] Main steel structure;

[0011] Fixtures;

[0012] A water tank is arranged above the main steel structure, and the water tank is connected to the building downpipe;

[0013] A support plate is vertically arranged in the water tank, two clamps are provided and are horizontally arranged on the left and right sides of the support plate, and the PTFE membrane is connected to the clamps to form a PTFE membrane structure extending outward from the support plate;

[0014] The stiffening plate is arranged on both sides of the support plate, one end of the stiffening plate is connected to the support plate, and the other end is connected to the water tank.

[0015] Furthermore, a vertical waist-shaped hole is provided on the support plate, and the support plate is installed in the waist-shaped hole.

[0016] Furthermore, the main steel structure and the water tank are connected via a stiffening plate.

[0017] Furthermore, the support plates and stiffening plates are arranged in a cross shape.

[0018] Working principle:

[0019] The PTFE membrane is fixed to the support plate by a clamp, and the two sides of the support plate are reinforced by stiffening plates to improve the strength of the support plate. The area between the two PTFE membranes is the gutter area, where rainwater is collected and flows along the gutter to the downpipe at the edge of the building, and finally discharged from the downpipe, thus solving the waterproofing problem caused by the split membrane.

[0020] The construction process is as follows:

[0021] (1) Weld the water tank and stiffening plate to the main steel structure;

[0022] (2) Weld the support plate in the middle of the water tank, and then weld the stiffening plate between the support plate and the water tank;

[0023] (3) Connect the PTFE membrane edges through a special aluminum profile fixture;

[0024] (4) Use M10 galvanized bolts to connect the special aluminum profile clamp and the support plate, and tighten the bolts of the clamp to achieve the tensioning of the PTFE membrane.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] (1) The PTFE membrane tensioning node provided by the utility model realizes the separate membrane installation of the PTFE membrane while meeting the PTFE membrane tensioning requirements, thereby reducing the installation difficulty.

[0027] (2) Effectively solve the waterproofing problem caused by the split membrane installation.

[0028] (3) The left and right PTFE membranes share the same support plate, which can reduce the overall weight while ensuring strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0036] Example 1

[0037] like Figure 1-4 As shown, this embodiment provides a PTFE membrane tensioning node, including: a main steel structure 1, a water trough 3, a support plate 4, a stiffening plate 5, a clamp 6 and a PTFE membrane 7. A stiffening plate 2 is arranged between the water trough 3 and the main steel structure 1. The stiffening plate 2 is made of 8mm thick steel plate, which can be arranged along the length direction of the water trough 3 or along the width direction of the water trough 3. If the water trough 3 is arranged in the width direction, a stiffening plate 2 is arranged every 300mm.

[0038] The stiffening plate 2 is welded to the main steel structure 1, and the water tank 3 is welded above the stiffening plate 2. The water tank 3 is made of a 6mm thick steel plate into a C-shaped water tank with a depth of 130mm and a width of 250mm. The water tank 3 is connected to the downpipe 8 at the edge of the building so that rainwater flows into the downpipe 8 along the water tank 3 to achieve the drainage function, thereby solving the waterproof problem caused by the membrane installation. The support plate 4 is vertically arranged in the middle of the water tank 3. The support plate 4 is a steel plate of 170mm*100mm*8mm to ensure that there are enough installation positions for the clamps 6 and to ensure sufficient strength. The two adjacent support plates 4 are spaced 300mm apart. Two vertical waist-shaped holes 41 are provided on the support plate 4. The two waist-shaped holes 41 are used to install the left and right clamps 6 respectively. By adjusting the position of the clamp 6 in the waist-shaped hole 41, the height of the PTFE membrane 7 can be slightly adjusted, so that the transition of the building canopy surface formed by a number of PTFE membranes 7 is smooth, improving the integrity and the aesthetics after construction.

[0039] Stiffening plates 5 are provided on both sides of the support plate 4. The support plate 4 and the stiffening plates 5 are arranged in a cross shape. The stiffening plates 5 are made of 100mm*114mm*6mm steel plates, which are used to strengthen the strength of the support plate 4 to avoid deformation of the support plate 4 during and after the tensioning of the PTFE membrane 7. The PTFE membrane 7 is evenly stressed, thereby improving the reliability of the node.

[0040] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
