Description

Technical Field

[0001] This utility model belongs to the field of extruded board technology and relates to a high-strength, deformation-resistant extruded board. Background Technology

[0002] The shortcomings of existing extruded polystyrene (XPS) boards in terms of strength and deformation resistance mainly stem from their material properties and manufacturing process. XPS boards are rigid, closed-cell foam plastics made from polystyrene resin through an extrusion process. Their strength and deformation resistance are limited by the molecular structure of the material and the uniformity of the foam pores. During production, improper temperature and pressure control can lead to weak foam pore walls, thereby reducing the overall strength and deformation resistance of the material. Furthermore, XPS boards may exhibit compression deformation or poor dimensional stability under long-term stress or changes in ambient temperature.

[0003] Conventional solutions include increasing the density of the extruded polystyrene (XPS) board, using cross-linking agents to improve intermolecular bonding, and adding reinforcing materials such as glass fiber. However, these methods also have drawbacks. Increasing density can improve strength and resistance to deformation, but it also increases the thermal conductivity of the material, reducing its insulation performance and increasing costs. While using cross-linking agents can improve intermolecular bonding, it may make the material more brittle and reduce its flexibility and impact resistance. Adding reinforcing materials can improve strength and dimensional stability, but different reinforcing materials may result in varying strength gains and may affect material uniformity and processing performance. Therefore, there is an urgent need for a high-strength, deformation-resistant XPS board to address these issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-strength, deformation-resistant extruded polystyrene board to solve the problems mentioned in the background art.

[0006] The plate includes an outer reinforcing edge and a reinforcing core column. The outer reinforcing edge has a rectangular ring structure in its top cross-section. The outer reinforcing edge is made of a wood material. An inner core board is provided on the inner side of the outer reinforcing edge.

[0007] The lower ends of both the left and right sides of the inner core plate are provided with a set of inner support plates to improve the support strength of the multi-layer inner core plate. The inner support plates are arranged perpendicular to the inner core plate. The outer side of the inner support plate is provided with two sets of outer grooves for positioning and fitting with the inner sides of the left and right ends of the side shell. The inner side of each set of inner support plates is provided with a set of reinforcing side seats to improve the support strength of the inner support plate. The multi-layer inner core plate can be supported by using the reinforcing side seats, limiting core blocks, core seats and side positioning seats inside the plate body, thereby improving the compressive strength of the inner core plate and improving the overall strength of the plate body.

[0008] In a preferred embodiment, the front cross-section of the reinforcing side seat is a right-angled trapezoidal structure, the reinforcing side seat is a wooden support, and the right-angled side of the reinforcing side seat is attached to the inner side of the inner support plate. By using the reinforcing side seat and the inner support plate, the distance between the multiple inner core boards can be maintained, and the interior of the multiple inner core boards can be supported, thereby reducing the deformation of the multiple inner core boards after being squeezed.

The multi-layer inner core board can be supported by using the isosceles trapezoidal side positioning seats and core seats. The staggered side positioning seats and core seats can limit each other and improve the overall support effect of the inner core board.

[0010] In a preferred embodiment, the core seat is supported by a wooden material, and the side positioning seat is made of a polyethylene high-strength material. The center of the side positioning seat is provided with a set of limiting core blocks for maintaining the center counterweight of the side positioning seat. The front cross-section of the limiting core block is an isosceles trapezoidal structure and is a solid polyethylene block. By using the limiting core blocks, the positioning effect of the side positioning seat on the core seat can be improved, thereby preventing the loosening of the multi-layer inner core board.

[0011] In a preferred embodiment, a set of base plates is provided at the lower ends of several sets of core seats and several sets of side positioning seats, and a set of lower positioning seats is provided at the lower ends of the side positioning seats for mutual positioning and fitting within the base plates.

[0012] In a preferred embodiment, the lower positioning seat is provided with a set of reinforcing core columns on the left and right sides to maintain the bending strength of the overall extruded board, and a set of reinforcing plates is provided on the front and rear sides of the board to maintain the front and rear strength of the board.

The several sets of lower inserts are integral with the side shell, and the front cross-section of the lower insert is a concave structure.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: by using the reinforcing side seats, limiting core blocks, core seats, and side positioning seats inside the plate body to support the multi-layer inner core board, the compressive strength of the inner core board is improved, while the overall strength of the plate body is also improved. By using the reinforcing side seats and inner support plates, the distance between the multi-layer inner core boards is ensured, and the interior of the multi-layer inner core board is supported, thereby reducing the deformation of the multi-layer inner core board after being squeezed. By using the isosceles trapezoidal side positioning seats and core seats to support the interior of the multi-layer inner core board, the side positioning seats and core seats arranged in an alternating manner can limit each other and improve the overall support effect of the inner core board. By using the limiting core blocks, the positioning effect of the side positioning seats on the core seats is improved, thereby preventing the multi-layer inner core board from becoming loose.

[0027] Between the two sets of reinforcing side seats 14e, there are several sets of core seats 14f for maintaining the fitting height of the multi-layer inner core board 14b and several sets of side positioning seats 14g for ensuring the position of the core seats 14f.

Each set of core seats 14f and each set of side positioning seats 14g are staggered and respectively located on the front and rear sides of the multi-layer inner core board 14b.
