[0015] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0016] In the description of the embodiments of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct communication or an indirect communication through an intermediate medium. Among them, "fixing" means that they are connected to each other and the relative positional relationship after connection remains unchanged. The orientation terms mentioned in the embodiments of the present utility model, such as "inside", "outside", "top", "bottom", etc., are only with reference to the direction of the accompanying drawings. Therefore, the orientation terms used are for better and clearer description and understanding of the embodiments of the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation on the embodiments of the present utility model.

[0017] In the embodiments of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0018] In the embodiments of the present utility model, "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after.

[0019] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present utility model. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0020] As Figures 1 - 3 shown, the present utility model provides a heat-insulating formwork that does not need to be disassembled, which is characterized by comprising: a heat-insulating board 10, the heat-insulating board 10 having a first side 11, a second side 12, a third side 13, and a fourth side 14; the first side 11 and the second side 12 face away from each other, the third side 13 and the fourth side 14 face away from each other, tenon grooves 15 are respectively formed in the first side 11 and the third side 13, tenon blocks 16 protruding outward are respectively provided on the second side 12 and the fourth side 14, and a plurality of fixing nails 17 are further provided on the back surface of the heat-insulating board 10, and the fixing nails 17 are used for bonding with concrete during pouring;

[0021] Specifically, the thermal insulation board 10 is made of thermal insulation materials such as polystyrene board and polyurethane foam board; the thermal insulation board 10 is used as a formwork on one side during pouring in this application; due to transportation factors, the thermal insulation board 10 is usually made in a predetermined specification. To facilitate the splicing of multiple thermal insulation boards 10 in the later stage, tenon grooves 15 or tenon blocks 16 are provided on the four sides of the thermal insulation board 10. For the convenience of description, one side of the thermal insulation board 10 is defined as the first side 11, the two sides adjacent to the first side 11 are the third side 13 and the fourth side 14, and the side opposite to the first side 11 is the second side 12. The tenon grooves 15 are provided on the first side 11 and the third side 13, and the second side 12 and the fourth side 14 are protruding tenon blocks 16, which are convenient for splicing with the thermal insulation boards 10 in the direction where the first side 11 and the third side 13 are located. Adjacent two thermal insulation boards 10 are connected by inserting the tenon blocks 16 into the tenon grooves 15, and the connection between adjacent two thermal insulation boards 10 is realized by the concave-convex fit. Among them, the tenon blocks 16 and the tenon grooves 15 are in a tight fit, which can prevent the leakage of concrete during pouring and also play a good waterproofing effect on the exterior wall after the later installation and forming; to improve the bonding force between the thermal insulation board 10 and the concrete, a number of fixing nails 17 are provided on the back of the thermal insulation board 10, that is, the side where the concrete wall 19 is poured. Both ends of the fixing nail 17 are hook-shaped to improve the bonding strength with the thermal insulation board 10 and the concrete and ensure the fixing strength of the thermal insulation board 10.

[0022] Installation process: The thermal insulation board 10 is prefabricated in the factory and transported to the construction site for hoisting and installation. It is used as the outer surface formwork for the exterior wall pouring. After the inner formwork of the exterior wall is installed, the concrete can be poured. After pouring, the construction of the entire concrete wall 19 and the thermal insulation layer is completed. After the concrete solidifies, only the inner formwork needs to be removed, and the outer one does not need to be removed, making the construction convenient and fast.

[0023] Further, multiple strengthening layers are filled in the thermal insulation board 10;

[0024] Specifically, since the thermal insulation board 10 is used to replace the traditional formwork in this application and does not need to be removed in the later stage, to improve the shear resistance and strength of the thermal insulation board 10, 2-3 layers of strengthening layers are filled in the thermal insulation board 10 during its production to improve the strength and shear resistance of the thermal insulation board 10 in the later stage. Preferably, the strengthening layer is made of non-woven fabric or mesh fabric.

[0025] Further, a number of protruding back ribs 18 are also provided at intervals on the back of the thermal insulation board 10;

[0026] Specifically, for facilitating the later riveting operation and enhancing the riveting strength, a number of back ribs 18 protruding from the surface of the thermal insulation board 10 are provided on the back of the thermal insulation board 10, and the back ribs 18 are covered by concrete during concrete pouring.

[0027] In summary, by replacing the traditional formwork with the thermal insulation board 10 in this application, it can not only serve as a fixed formwork for strength but also as a later thermal insulation layer, achieving multiple benefits at once. Moreover, it still needs to be removed later, improving the construction efficiency. At the same time, the thermal insulation layer of the building can be carried out synchronously with the pouring of the exterior wall, simplifying the construction process, enabling quick construction, saving energy and the environment, and reducing costs.

[0028] The present utility model is not limited solely to what is described in the specification and embodiments. Therefore, for those skilled in the art, additional advantages and modifications can be easily achieved. Thus, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present utility model is not limited to specific details, representative devices, and the illustrated examples shown and described herein.
