[0032] 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.
[0033] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a non-removable thermal insulation template for building foundation beams, comprising a thermal insulation template body 1, a fixing component on the side wall of the thermal insulation template body 1, and a thermal insulation component inside the thermal insulation template body 1; the fixing component includes a T-shaped block 2, the side wall of the T-shaped block 2 is fixedly connected to the side wall of the thermal insulation template body 1, the T-shaped block 2 has a slot 3 inside, the thermal insulation template body 1 has a slot 4 inside, the thermal insulation template body 1 has a slot 5 inside, the thermal insulation template body 1 has a slot 6 inside, and the thermal insulation template body 1 has a fixed... The insulation template body 1 has an insert block 8 inside the slot 7. The side wall of the insert block 8 is slidably connected to the inside of slot 1 3 and slot 2 5. The insert block 8 has a spring 9 inside and a locking block 10 is slidably connected inside. The side wall of the locking block 10 is slidably connected to the inside of slot 2 6. The side wall of the insert block 8 is fixedly connected to a positioning block 11. One end of the spring 9 is fixedly connected to the inside of the insert block 8, and the other end of the spring 9 is fixedly connected to the side wall of the locking block 10. The side wall of the T-shaped block 2 is slidably connected to the inside of slot 1 4, and the side wall of the positioning block 11 is slidably connected to the inside of the positioning slot 7.
[0034] When connecting two insulation template bodies 1, first align the T-shaped block 2 on the side wall of one template with the slot 4 of the other template, and slide the T-shaped block 2 into the slot 4. The T-shaped block 2 and the slot 4 fit together, effectively limiting the relative positions of the two templates in the horizontal and vertical directions, thus playing a positioning role. At the same time, the friction between the T-shaped block 2 and the slot 4 achieves initial fixation. Next, insert the insert block 8 into the slot 3 opened inside the T-shaped block 2, and push the insert block 8 towards the slot 5. Slots 3 and 5 provide a guide path for the movement of the insert block 8. Since the side wall of the insert block 8 is slidably connected to slots 3 and 5, the insert block 8 can move within these two slots. During this process, the insert block 8 moves together with the positioning block 11. The cooperation between the positioning block 11 and the positioning groove 7 further constrains the movement trajectory of the insertion block 8, preventing the insertion block 8 from shifting due to external interference during insertion. When the insertion block 8 is inserted, the locking block 10 will first contact the edge of the second groove 6. As the insertion block 8 continues to penetrate deeper, the locking block 10 is squeezed by the edge of the second groove 6, compressing the spring 9 inside the insertion block 8, and then sliding into the second groove 6. When the locking block 10 is fully inserted into the second groove 6, the spring 9 returns to its deformation and applies an outward elastic force to the locking block 10. Under the elastic force of the spring 9, the locking block 10 is locked inside the second groove 6, thereby fixing the two insulation template bodies 1 together, realizing a fast and stable connection between the insulation templates, and meeting the requirements for template connection efficiency and stability in building construction.
[0035] Reference Figure 1 and Figure 3 The insulation component includes a protective layer 12 located inside the insulation template body 1. A reflective heat insulation layer 13 is provided on the side wall of the protective layer 12, an insulation layer 14 is provided on the side wall of the reflective heat insulation layer 13, an adhesive layer 15 is provided on the side wall of the insulation layer 14, and an interface bonding layer 16 is provided on the side wall of the adhesive layer 15. The protective layer 12 is made of cement as the matrix and mixed with alkali-resistant glass fiber to protect the internal insulation layer 14 from physical damage. The reflective heat insulation layer 13 is made of aluminum foil and fiberglass cloth composite to assist the insulation layer 14 in improving the heat insulation and energy saving effect. The insulation layer 14 is made of aerogel felt to prevent heat conduction and improve the heat insulation performance of the insulation template body 1. The adhesive layer 15 is made of cement, graded sand and redispersible latex powder to enhance the interlayer adhesion. The interface bonding layer 16 is made of acrylic emulsion, hydroxyethyl cellulose and sodium hexametaphosphate to improve the bonding performance between the template and the ground beam concrete and improve the durability of the heat insulation effect.
[0036] The protective layer 12 uses cement as a matrix and incorporates alkali-resistant glass fiber and other reinforcing materials. It is manufactured through processes such as pulping, molding, and curing. It effectively resists collisions and scratches during construction, thus protecting the internal insulation layer 14 from physical damage. Simultaneously, the protective layer 12 has excellent waterproof and moisture-proof properties, making it difficult for external rainwater and moisture to penetrate. It also possesses certain fire-resistant properties, which can, to some extent, prevent the spread of fire, improving the overall safety and durability of the formwork. The reflective insulation layer 13 is composed of aluminum foil composite fiberglass cloth. The aluminum foil has high reflectivity; when sunlight shines on the insulation formwork body 1, the aluminum foil can reflect most of the sunlight. The insulation layer 14 reflects solar radiation heat away, reducing heat transfer into the template and effectively lowering the temperature rise caused by sunlight. This makes the ambient temperature of the insulation layer 14 more stable. The fiberglass cloth provides the reflective insulation layer 13 with a certain strength and flexibility, ensuring it is not easily damaged even by slight bending or pulling during construction, thus guaranteeing the continued effectiveness of its reflective insulation function. The insulation layer 14 uses aerogel felt. Aerogel is a lightweight material with a nanoporous structure, made into a felt shape for easy application. Its extremely low thermal conductivity makes it difficult for heat to be conducted through the insulation layer 14, preventing heat from being conducted through the insulation layer 14 in low-temperature environments. In a low-temperature environment, heat is difficult to transfer from the outside to the ground beam through the insulation layer 14, and heat emitted from the ground beam is also difficult to dissipate to the outside through the insulation layer 14. This significantly reduces heat exchange between the ground beam and the external environment, greatly improving the thermal insulation performance of the insulation template, reducing energy consumption, and ensuring the temperature stability of the ground beam under different climatic conditions. The bonding layer 15 is composed of cement, graded sand, redispersible latex powder, additives, etc., mixed in a certain proportion. The bonding layer 15 bonds the interface bonding layer 16 between the insulation layer 14 and the ground beam, enhancing interlayer adhesion, resisting pressure, and preventing interlayer displacement and separation. When the temperature changes, it adapts to the expansion and contraction of each layer of material. The interface bonding layer 16 is made of acrylic emulsion, hydroxyethyl cellulose, and sodium hexametaphosphate. Before construction, it is applied to the side of the formwork that contacts the ground beam. During the concrete pouring process, the interface bonding layer 16 interacts with the ground beam concrete, improving the bonding performance between the formwork and the ground beam concrete. This allows the formwork and the ground beam concrete to adhere to each other, enhancing the adhesion between them. During long-term use, even if affected by external vibrations, slight settlement, or other factors, the insulation formwork and the ground beam will not experience problems such as hollowing or falling off, ensuring the integrity of the structure and the durability of the insulation effect.
[0037] Working principle: When connecting two insulation template bodies 1, first align the T-shaped block 2 on the side wall of one template with the slot 4 of the other template, and slide the T-shaped block 2 into the slot 4 for positioning and initial fixation. Then, insert the insert block 8 into the slot 3 inside the T-shaped block 2, and push the insert block 8 towards the slot 5. Since the side wall of the insert block 8 is slidably connected to both slot 3 and slot 5, it can move within these two slots. During this process, the insert block 8 moves along with the positioning block 11, which slides along the positioning groove 7, further ensuring the accuracy and stability of the movement of the insert block 8 and preventing it from shifting during insertion. When the insert block 8 is inserted, the locking block 10 will first contact the edge of the slot 6. As the insert block 8 continues to penetrate deeper, the locking block 10 is subjected to... The compression of the edge of the slot 26 compresses the spring 9 inside the insert 8, causing it to slide into the slot 26. When the insert 10 is fully inserted into the slot 26, the spring 9 returns to its original shape, applying an outward elastic force to the insert 10, causing the insert 10 to be locked inside the slot 26, thus fixing the two insulation template bodies 1 together. This achieves a quick and stable connection between the insulation templates. The protective layer 12 can effectively resist collisions and scratches during construction, protecting the inner insulation layer 14 from physical damage. The reflective heat insulation layer 13 has a high reflectivity, which can reflect most of the solar radiation heat when sunlight shines on the insulation template, reducing the amount of heat entering the template. The insulation layer 14 has an extremely low thermal conductivity, making it difficult for heat to be conducted through the insulation layer 14, which can significantly reduce the heat exchange between the ground beam and the external environment. The bonding layer 15 can enhance the interlayer adhesion and prevent the interlayer separation caused by factors such as temperature changes and concrete pouring pressure, ensuring the structural integrity and stability of the thermal insulation formwork during construction and use. The interface bonding layer 16 can improve the bonding performance between the formwork and the ground beam concrete, so that the thermal insulation formwork and the ground beam concrete are firmly bonded.
