[0002] In recent years, my country has raised its requirements for energy conservation and environmental protection in residential construction, leading to the rapid rise of low-carbon, green prefabricated buildings. With the further promotion and application of ultra-low energy consumption buildings and near-zero energy consumption buildings, energy-saving design standards are placing higher demands on the performance of exterior wall insulation. Traditional exterior wall insulation processes are complex, labor-intensive, difficult to construct, energy-intensive, time-consuming, and have a short service life, making them prone to detachment. Utility Model Content

[0003] The purpose of this utility model is to provide a low-carbon structural node that enhances the adhesion of the integrated thermal insulation template without dismantling of the exterior wall, so as to solve the problems mentioned in the background art, such as complicated process of prefabricated building exterior wall insulation, high labor intensity, high construction difficulty, high energy consumption, long construction time, short service life, and easy detachment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-carbon structural node for enhancing the adhesion of an integrated thermal insulation template for exterior walls, comprising a protective layer, alkali-resistant fiberglass mesh, thermosetting composite polystyrene board, and horn-shaped connection points. The protective layer, alkali-resistant fiberglass mesh, thermosetting composite polystyrene board, and horn-shaped connection points are processed by a prefabrication plant to form an integrated thermal insulation template for exterior walls. The horn-shaped connection points are used for connection with cast-in-place concrete. Special pre-embedded anchors are embedded between the cast-in-place concrete and the integrated thermal insulation template. An inner wooden template is set on the outside of the cast-in-place concrete. The inner wooden template is formed by vertical square timber secondary ribs and horizontal steel pipe back ribs connected to the vertical square timber secondary ribs and horizontal steel pipe back ribs on the outside of the protective layer through tie rods to form a template support system.

[0005] Preferably, the protective layer is a 5mm crack-resistant mortar, the inner side of the protective layer is an alkali-resistant fiberglass mesh, and the inner side of the alkali-resistant fiberglass mesh is a 95mm thick thermosetting composite polystyrene board.

[0006] Preferably, the upper horizontal length of the horn-shaped connection point is 40mm, the lower horizontal length is 30mm, and the vertical length is 50mm. The horn-shaped connection point is set every 500mm along the height direction of the integrated thermal insulation non-removable template.

[0007] Preferably, the effective anchoring length of the special pre-installed anchor is not less than 90mm. For buildings with a height of less than 24m, there are no less than 6 anchors per square meter. For buildings with a height of less than 24-50m, there are no less than 8 anchors per square meter. For buildings with a height of more than 50m, there are no less than 10 anchors per square meter.

[0008] Preferably, the vertical square timber secondary beams are 50mm x 100mm square timbers with a spacing of 250mm.

[0009] Preferably, the transverse steel pipe back rib consists of two Φ48x35mm steel pipes.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This low-carbon structural node with enhanced integrated thermal insulation and no-removal formwork adhesion is made possible by the fact that the thermal insulation system is prefabricated in the prefabrication plant and the finished product is directly hoisted and installed on site. Compared with traditional thermal insulation construction, the process is simpler, the labor intensity is reduced, the construction difficulty is reduced, the energy consumption is reduced, the installation speed is faster, and the construction time is greatly shortened.

[0012] 2. This low-carbon structural joint enhances the adhesion of the integrated exterior wall insulation formwork without removal. Compared to the planar structure on the inner side of traditional insulation boards, this utility model features a horn-shaped structure on the inner side, which strengthens the bond with the cast-in-place concrete, extends the service life of the building's exterior wall insulation, and prevents quality problems such as insulation detachment. The integrated exterior wall insulation formwork acts as exterior wall formwork and does not need to be removed, meeting the requirements of green and low-carbon construction.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This embodiment provides a low-carbon structural node for enhancing the adhesion of integrated thermal insulation templates for exterior walls. It includes a protective layer 1, alkali-resistant fiberglass mesh 2, thermosetting composite polystyrene board 3, and horn-shaped connection points 4. The protective layer 1, alkali-resistant fiberglass mesh 2, thermosetting composite polystyrene board 3, and horn-shaped connection points 4 are fabricated by a prefabrication plant to form integrated thermal insulation templates for exterior walls. The horn-shaped connection points 4 are used for connection with cast-in-place concrete 10. Special pre-embedded anchors 5 are embedded between the cast-in-place concrete 10 and the integrated thermal insulation template. An inner wooden template 9 is installed on the outside of the cast-in-place concrete 10. The inner wooden template 9 is formed by vertical square timber secondary ribs 6 and horizontal steel pipe back ribs 7 connected to the vertical square timber secondary ribs 6 and horizontal steel pipe back ribs 7 on the outside of the protective layer 1 via tie rods 8, forming a template support system. The vertical square timber secondary ribs 6 are 50mm x 100mm square timbers spaced 250mm apart, and the horizontal steel pipe back ribs 7 are two Φ48x35mm steel pipes.

[0019] In the above embodiment, the protective layer 1 is a 5mm crack-resistant mortar, the inner side of the protective layer 1 is an alkali-resistant fiberglass mesh 2, and the inner side of the alkali-resistant fiberglass mesh 2 is a 95mm thick thermosetting composite polystyrene board 3. Specific parameters can be determined according to the drawing requirements. Secondly, the upper horizontal length of the horn-shaped connection point 4 is 40mm, the lower horizontal length is 30mm, and the vertical length is 50mm. Horn-shaped connection points 4 are set every 500mm along the height direction of the integrated thermal insulation formwork, and the specific length can be determined according to the actual site conditions. The effective anchoring length of the dedicated pre-installed anchors 5 is not less than 90mm. For buildings with a height less than 24m, there are no less than 6 anchors per square meter; for buildings with a height less than 24-50m, there are no less than 8 anchors per square meter; and for buildings with a height greater than 50m, there are no less than 10 anchors per square meter. Each integrated thermal insulation formwork panel must have at least one dedicated pre-installed anchor 5.

[0020] During construction, first determine the layout of the integrated thermal insulation formwork on the exterior facade. In advance, at the prefabrication plant, process the protective layer 1, alkali-resistant fiberglass mesh 2, thermosetting composite polystyrene board 3, and horn-shaped connection points 4 to create the integrated thermal insulation formwork. Then, hoist the molded and cured integrated thermal insulation formwork to the corresponding floor and exterior facade location. Next, embed special pre-installed anchors 5 between the integrated thermal insulation formwork and the cast-in-place concrete 10. Install inner wooden formwork 9 on the outside of the internal reinforcing steel bars of the cast-in-place concrete 10. Install vertical square wooden secondary ribs 6, horizontal steel pipe back ribs 7, and tie rods 8 on the outside of the inner wooden formwork 9 and the protective layer 1 to form a formwork support system. Then, adjust the formwork and supports, pour the cast-in-place concrete 10, and finally, remove the non-integrated thermal insulation formwork and supports, and allow the concrete to cure.

[0021] In summary, this utility model provides a low-carbon structural node that enhances the adhesion of integrated exterior wall insulation formwork without the need for removal. Because the exterior wall insulation system is prefabricated as a whole in a precast component factory, the finished product can be directly hoisted and installed on-site, reducing labor intensity, construction difficulty, energy consumption, and installation speed, thus shortening construction time. The horn-shaped connection point enhances the bonding strength with the cast-in-place concrete, extending the service life of the building's exterior wall insulation and preventing quality problems such as insulation detachment. By using the integrated exterior wall insulation formwork without removal, it fulfills the requirements of green and low-carbon construction.
