Description

Technical Field

[0001] The utility model relates to the technical field of regenerated composite keels, in particular to a novel regenerated composite keel structure. Background Technique

[0002] At present, most domestic construction projects still use traditional wooden formwork for reinforcement. Ordinary wooden formwork can be used about 1 - 2 times, generating a large amount of waste formwork every year. A large amount of waste wooden formwork is difficult to be processed and utilized, and most of it is burned as fuel, causing serious pollution to the environment. In domestic construction projects at present, the utilization rate of traditional wooden beams reaches 70%. Traditional wooden beams are sourced from nature, causing no small damage to the environment. Regenerated composite keels are re - processed from traditional waste formwork and are made through processes such as high - temperature extrusion and thermosetting molding. Their dimensions can be designed according to requirements, and they have great potential in aspects such as green, low - carbon, and environmental protection.

[0003] However, with the application of regenerated composite keels in construction projects, problems such as fracture, shedding of the external fiberglass cloth, and low turnover times have emerged, revealing that the current regenerated composite keel structure still needs to be optimized. Thus, how to improve the performance of regenerated composite keels has become an urgent problem to be solved in this field. Content of the Utility Model

The inner core includes a first basic structure and a second basic structure. The first basic structure and the second basic structure are connected by the first connection structure, where the first connection structure is white latex adhesive. The outer surface of the inner core is strip - tied with the second connection structure, and the outer surface of the inner core and the outer surface of the second connection structure are wrapped and connected with the third connection structure;

[0006] The first basic structure is formed by splicing a number of regularly - shaped waste formwork;

[0007] The second basic structure is formed by splicing a number of regularly - shaped waste wooden beams;

[0008] The second connection structure is a strip - shaped aramid fiber, and the width of the strip - shaped aramid fiber is 5 mm, the thickness is 0.1 mm, and the interval is 100 mm, which is tied and wrapped around the inner core of the regenerated composite keel;

[0009] The third connecting structure is a fiberglass mesh cloth, and the thickness of the fiberglass mesh cloth is 0.2 mm. The fiberglass mesh cloth is connected to the inner core by hot-pressing a new binder at a temperature of 100 °C with a hot press.

[0010] Preferably, the tensile strength of the fiberglass mesh cloth > 1200 MPa and the compressive strength > 200 MPa.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the novel regenerated composite keel structure provided by the present utility model, the combination of the first connecting structure, the second connecting structure, and the third connecting structure with the inner core improves the shear and bending strength of the regenerated composite keel; due to the function of the third connecting structure, the contact area between the inner core and the outside world is reduced, avoiding the reaction of the first basic structure and the second basic structure with air, improving the durability of the regenerated composite keel, thereby increasing the turnover times, reducing costs, and being green and environmentally friendly.
