Abstract

A composite structural angle material, which uses plastic composite materials and structural devices to strengthen the angle material and the weight reduction structure, is extruded by a special-shaped co-extrusion machine, which enhances the traditional plastic foam angle material. Its nailing force is not strong, and the length is soft. The shortcomings of rigidity include: the mixed structure of rigid plastic and foamed plastic, the construction of rigid plastic, the use of I-beam structural effects, or the combination of most box and culvert structures, or circular structures to generate supporting structural forces to enhance The angle material is stressed in the longitudinal direction to resist its weakness in the longitudinal direction and can be strengthened, and then the foamed plastic is supplemented to fill its space to strengthen and solidify the entire plastic angle material.

Description

Angle of composite structure

The invention is a composite structural angle material, which uses plastic composite material, a mixture of hard plastic and foamed plastic, and uses hard plastic to construct an I-beam structure device, or a combination structure of most box-culvert structures, or a circular structure. Filled with foamed plastic and made of composite structural angle material.

At present, there are foaming angles in the building materials market. Solid foaming angles are mainly used because plastic materials are valued by weight. For example, if rigid plastics are used as solid angles, their weight is too heavy and the unit price is too expensive. Therefore, they are all mixed with recycled plastic. The fireproofing agent and foaming agent are mixed to make foamed angle material; however, the foamed angle material is loose in its nailing force, soft in the longitudinal direction, and insufficient in stiffness. It is not as strong as natural wood angle material with natural long fibers, which is criticized by users. , So use the invention to improve.

The angle of a composite structure of the present invention is made of a composite material, a mixed structure of hard plastic and foamed plastic, extruded by a special co-extrusion machine, a structure constructed of hard plastic, and an I-beam structure effect or a combination of most box-culvert structure effects. Or a circular structure, which generates a supporting structural force to enhance the long-term stress of the angle material, to resist its weakness in the long-term direction, and to be strong, and the tough and hard plastic has a very good nailing force, and then supplements the foam. Plastic fills its space, so that the entire plastic angle material is strengthened and strong, and the nailing force is good, and appropriate graphic holes are reserved at appropriate places. The principle is not to affect the structural strength. Measures to reduce overall weight.
