[0014] The present invention provides another technical solution: a construction method of a double-sleeve thermal bridge protection pipeline wall penetration structure, comprising the following steps:

[0015] S1: attaching a polystyrene outer plate to the outer wall of the outer wall, punching holes in the outer wall and the polystyrene outer plate, and at the same time, additionally digging a first groove around the punching position inside the polystyrene outer plate;

[0016] S2: Filling the outer sleeve in the outer wall, passing the inner sleeve through the through hole of the polystyrene outer plate and the inner wall, and filling the first filling ring into the gap between the inner sleeve and the polystyrene outer plate, so that the extension rod connected to the first filling ring extends to the first groove position inside the polystyrene outer plate;

[0017] S3: fix the limiting plate to one end of the extension rod by a first bolt, pre-compress the expansion insulation block to fit the limiting plate, and fix the limiting block to the side of the outer sleeve facing the outer wall by a second bolt, so that the limiting block is fixed toward the limiting plate;

[0021] When assembling the double-sleeve heat-proof bridge pipeline wall-penetrating structure of the present invention, the foamed polyurethane can be transmitted to the second filling cavity through the transmission cavity. As the foamed polyurethane is transmitted, the foamed polyurethane inside the second filling cavity will actively push the outer sleeves and the limiting plates on both sides. While pushing the outer sleeves, the outer sleeves will move toward the pre-compression expansion insulation block and the limiting plate through the limiting block and squeeze the other side of the limiting plate. As the foamed polyurethane inside the transmission cavity is transmitted, the foamed polyurethane will fill the second filling cavity, the first groove and the second groove, and can directly fill the gaps inside the double-sleeve heat-proof bridge pipeline wall-penetrating structure and the construction method, avoiding the gaps affecting the stability of the double-sleeve heat-proof bridge pipeline wall-penetrating structure and the construction method. Completely filling the gaps can improve the heat insulation effect and water-proof effect after assembly, and there is no need for the sealing effect to make it difficult for the foamed polyurethane applied when the gap position is small to completely cover the required application position, which is convenient for the user to apply and improves the application efficiency and filling effect.

The waterproof breathable membrane can improve the effect of the polystyrene outer plate 1 after attachment, and improve the practical life and practical effect of the polystyrene outer plate 1 after attachment;

[0032] Among them, an inner sleeve 5 is provided through the middle position of the polystyrene outer plate 1 and the outer wall 2, and a wall-penetrating pipe 8 is provided inside the inner sleeve 5. Through the wall-penetrating pipe 8 and the inner sleeve 5, a double sleeve is penetrated through the wall. The penetration of the double sleeve can improve the heat release effect and avoid the transfer of heat.

[0033] In addition, a first filling ring 3 is provided on the outer side of the inner sleeve 5 close to the polystyrene outer plate 1, and the first filling ring 3 can fill the gap between the inner sleeve 5 and the polystyrene outer plate 1 to improve the sealing effect;

[0034] In order to improve the filling effect of the first filling ring 3 and the precision of the fitting between the polystyrene outer plate 1 and the outer wall 2, an outer sleeve 9 is arranged around the outer sleeve 5 located at the outer wall 2, and an extension rod 13 is arranged on the first filling ring 3 to extend into the polystyrene outer plate 1, and a limiting plate 14 is arranged at one end of the extension rod 13, and the limiting plate 14 is fixedly connected to one end of the extension rod 13 by a first bolt 15, and the outer sleeve 9 can be prevented from falling off by the protruding limiting plate 14, and the cross-section of the outer sleeve 9 is L-shaped, and the outer sleeve 9 and the limiting plate 14 are relatively restricted to prevent falling off;

[0035] In order to avoid the formation of gaps inside the through-wall structure after the outer sleeve 9 and the limiting plate 14 are completely installed, as shown in FIG. Figure 3 and Figure 5As shown, a surrounding second filling cavity 17 is provided between the limiting plate 14 and the outer sleeve 9. When filling the second filling cavity 17 with filling material, the limiting plate 14 and the outer sleeve 9 can be squeezed, and the squeezing can avoid the generation of gaps inside the through-wall structure:

[0036] Among them, in order to facilitate the filling of the second filling cavity 17, the extension rod 13 is evenly distributed with four, and the outside of the four extension rods 13 is provided with a first groove 21, the first groove 21 is connected with the second filling cavity 17, and the material filled into the second filling cavity 17 will be filled into the first groove 21 as the material is continuously transmitted, and the extension rod 13 can be fixed by the first groove 21 to further fill the gap between the through-wall structures, and the two sides of the extension rod 13 are recessed with second grooves 22, and the recessed second grooves 22 can further improve the stability of the installation of the extension rod 13;

[0037] In addition, a transmission cavity 20 is provided inside one of the extension rods 13, and the transmission cavity 20 penetrates the extension rod 13 from one side of the first filling ring 3 and extends to the inside of the second filling cavity 17. The filling material can be squeezed through the transmission cavity 20 so that the material is completely filled into the second filling cavity 17, the second groove 22 and the first groove 21. The complete filling can avoid the formation of gaps in the double-sleeve thermal bridge pipeline wall penetration structure and affect the subsequent use;

[0038] In order to facilitate the restriction of the restriction plate 14 so that both sides of the restriction plate 14 are subjected to thrust, thereby improving the stability of the double-sleeve anti-heat bridge pipeline wall-penetrating structure when in use, a restriction block 10 is arranged on the outside of the outer sleeve 9 toward the outside of the outer wall 2, and the restriction block 10 is fixedly connected to the inside of the outer sleeve 9 by a second bolt 16, and the rotation of the second bolt 16 facilitates the fixation of the restriction block 10, and a pre-compression expansion insulation block 11 is arranged around the restriction block 10 and the restriction plate 14. After the material is filled in the second filling cavity 17, the outer sleeve 9 will be squeezed and move toward the polystyrene outer plate 1. The outer sleeve 9 is squeezed and moved laterally, and the restriction plate 14 will be squeezed from another direction by the restriction block 10. Both sides of the restriction plate 14 are squeezed, and as the filling material in the second filling cavity 17 is filled, the gap in the double-sleeve anti-heat bridge pipeline wall-penetrating structure can be avoided;

A third filling ring 6 is pre-filled, and a material is filled on one side of the third filling ring 6 and the first filling cavity 12 between the inner sleeve 5 and the hard polyurethane foam plastic 7. After the material is completely filled, the last third filling ring 6 is inserted between the inner sleeve 5 and the hard polyurethane foam plastic 7 to achieve squeezing of the first filling cavity 12 and filling of the gap between the inner sleeve 5 and the hard polyurethane foam plastic 7.

[0041] The material filled between the first filling cavity 12 , the second filling cavity 17 , the transmission cavity 20 , the first groove 21 and the second groove 22 is foamed polyurethane, which improves the waterproof effect, the heat insulation effect and the gap filling effect.
