    • The invention relates to a permanent plastic formwork system formed by two parallel surfaces, namely an outer surface (1) and an inner surface (2), consisting of a plurality of flat or longitudinally curved, hollow plastic slats (4) obtained by means of extrusion, provided internally with metal sections (13) providing them with rigidity and joined longitudinally by means of tongued-and-grooved ends (4a and 4b), separators (5) existing between the two surfaces. Said separators are provided with a threaded area (6) and an inclined appendage (8) for securing the rebar mesh (3) located between the surfaces. The slats (4) are secured to the ground using U-shaped parts (9) containing a threaded rod (10) that can be used to clamp and fix same. In addition, in closed structures reinforced internal elements can be incorporated diametrically, such as metal bars (11) with flat surfaces (12) at their ends enabling same to be secured to the above-mentioned inner surface (2).
    • 本发明涉及由两个平行表面(即,外表面)和内表面(2)形成的永久性塑料模板系统,所述外表面(1)和内表面(2)由多个平面或纵向弯曲的中空塑料板条组成, 挤压,内部设置有金属部分(13),为它们提供刚性并通过舌形和开槽的端部(4a和4b)纵向连接,分离器(5)存在于两个表面之间。 所述分离器设置有螺纹区域(6)和用于固定位于表面之间的钢筋网(3)的倾斜附件(8)。 板条(4)使用包含螺纹杆(10)的U形部件(9)固定到地面,该螺纹杆可用于夹紧和固定。 此外,在封闭结构中,加强的内部元件可以直径地结合,例如在其端部具有平坦表面(12)的金属棒(11),使得其能够固定到上述内表面(2)。
