Support module and clamp for limiting and pressing nonmetal support

A support module comprises a polymer support and a pressing and limiting clamp, wherein the polymer support is provided with a first side, a second side and an opening extending between the first side and the second side; the pressing and limiting clamp comprises a plate-shaped part connected with the second side and a component adjacent to at least part of the opening. The component penetrates the opening from the plate-shaped part to vertically extend so as to bear pressing force coming from a fastener connected with the polymer support. A clamp for limiting and pressing a nonmetal support comprises a first panel, a second panel and a rigid component, wherein the first panel and the second panel respectively cover the first side and the second side of the support; and the rigid component vertically extends out of the second panel and is adjacent to part of the opening so as to be connected with the fastener penetrating the opening. A support module for mounting surfaces comprises a clamp connected with the
