[0034] See also Figure 1 and Figure 2 In this embodiment, a connection structure between a PTFE membrane and a keel node is provided, which is used to fix the end of a PTFE membrane 20 at the keel node, wherein the keel node is the connection between a first keel 11 and a second keel 12, and the connection structure comprises: an opening 21 provided at the end of the PTFE membrane 20 corresponding to the penetration position of the second keel 12; a plurality of connectors 30 installed at the end of the PTFE membrane 20 and staggered with the opening 21, wherein the PTFE membrane 20 is wound around the first keel 11 and the second keel 12 is penetrated at the opening 21; a positioning plate 40 installed on the first keel 11 corresponding to the connector 30, wherein the connector 30 is detachably installed and connected to the positioning plate 40 and can be moved and adjusted in a direction close to or away from the second keel 12, and the connector 30 is moved and adjusted in a direction away from the second keel 12 to achieve tensioning of the PTFE membrane 20.

[0035] Preferably, the opening of the opening 21 is located at the end surface of the PTFE membrane 20 and the opening 21 penetrates the PTFE membrane 20. The edge line of the opening 21 is U-shaped.

[0036] In this embodiment, the connection structure avoids the influence of the second keel 12 by means of the opening 21, ensuring that the PTFE film 20 is closely attached to the first keel 11. The connecting member 30 moves together with the PTFE film 20, so that the tension of the PTFE film 20 can be adjusted, enabling the PTFE film 20 to always be in a tensioned state, solving the connection problem at the node between the structure of the PTFE film 20 and the keel, and avoiding affecting the structural strength of the PTFE film 20.

By winding and fixing the end of the PTFE film 20 on the insertion rod 60, the connection strength between the end of the PTFE film 20 and the insertion rod 60 is enhanced, and the insertion connection between the insertion rod 60 and the installation groove 52 makes it more convenient to achieve the clamping effect.

[0042] See Figure 1 and Figure 2, Further, the positioning plate 40 includes a first fixing section 41 installed on the first keel 11, and a second fixing section 42 vertically connected to a side of the first fixing section 41 away from the first keel 11; the setting direction of the first fixing section 41 is the same as that of the first keel 11 to support the guide rail 50; a part of the second fixing section 42 is higher than the top surface of the first fixing section 41 for installing and fixing the connecting piece 30.

[0050] Step 1: According to the detailed drawings, cut and fabricate the PTFE membrane 20 in the factory. During the fabrication of the PTFE membrane 20, strengthen the membrane material in the collision area separately, so that the strengthened area of the PTFE membrane 20 surrounds the opening 21 area of the PTFE membrane 20 and is firmly connected;

[0051] Step 2: Complete the measurement and layout work of the positioning plate 40 according to the design drawings using measuring equipment, and make marks at the same time for convenient later installation;

[0052] Step 3: The on-site construction personnel use the vertical transportation equipment to move the positioning plate 40 to the working surface, and then use the welding equipment to weld the positioning plate 40 to the first keel 11. To ensure the welding strength, the full-welding process is used for connection during welding;

[0053] Step 4: Subsequently, the construction personnel carry out the unfolding work (membrane tensioning) of the PTFE membrane 20. At the same time, the construction personnel install the guide rail 50 with the connecting piece 30 at the end of the PTFE membrane 20, and install the mounting piece 70 in the strengthened area at the same time. After it first passes through the strengthened area of the PTFE membrane 20 material, it then passes through the reserved bolt holes on the guide rail 50 to prepare for the tensioning of the subsequent PTFE membrane 20 and the strengthened area of the PTFE membrane 20 material.

[0054] Step 5: Pass the connecting piece 30 and the mounting piece 70 through the reserved bolt holes on the positioning plate 40, and then use the connecting piece 30 and the mounting piece 70 to complete the tensioning work of the PTFE membrane 20 and the strengthened area of the PTFE membrane 20 material. After the tensioning is completed, use the supporting nuts to complete the fixation.

[0055] See Figure 1 and Figure 2 , the present invention also provides a construction method for the connection structure between the PTFE membrane and the keel node as described above, including the following steps:

[0056] Install the positioning plate 40 on the first keel 11 corresponding to the connecting piece 30;

[0057] Wind the PTFE membrane 20 around the first keel 11, so that the second keel 12 passes through the opening 21;

[0058] Install and connect the connecting piece 30 to the positioning plate 40, and adjust the connecting piece 30 by moving it away from the second keel 12 to realize the tensioning of the PTFE membrane 20.

[0059] Furthermore, by moving and adjusting the position of the connecting piece 30 in the sliding groove 51, the connecting piece 30 is passed through and installed at the corresponding positioning hole.

[0060] Furthermore, the end of the PTFE membrane 20 and the guide rail 50 are installed and connected by inserting the insertion rod 60 connected to the end of the PTFE membrane 20 into the installation groove 52 from the end of the installation groove 52.

[0061] Furthermore, when installing the mounting member 70 , one of the fasteners 72 is inserted into one end of the through slot and passed out from the other end of the through slot, so that the mounting member 70 is passed through and installed on the PTFE membrane 20 .

[0062] By adopting the above technical solution, the present invention has the following beneficial effects:

[0063] The structure of the present invention is relatively simple and convenient to construct. On the basis of meeting the requirements of conventional PTFE membrane 20 roof installation and construction, it solves the problem of affecting the structural strength of the PTFE membrane 20 due to the collision between the facade PTFE membrane 20 structure and the keel node. At the same time, this process is respectively aimed at different areas. Through the setting of the connector 30 and the mounting member 70, the strength of the PTFE membrane 20 in the collision area can be significantly increased, and the integrity and strength of the structure can be ensured at the same time. It has the characteristics of simple structure and convenient construction. It can be used in the construction process of the PTFE membrane 20 structure, especially in the construction of the facade PTFE membrane 20 structure. And this process can adjust the PTFE membrane 20 material reinforcement area and the mounting member 70 according to the actual situation on site, and can be applied to other similar PTFE membrane 20 structures that conflict with the keel node. After application, it can effectively increase the strength of the PTFE membrane 20 in the collision area and improve the overall stability.
