一种钢结构挤塑板大型复合保温板，以挤塑板为主要的保温材料，并在挤塑板上设置有梯形连接槽以防止因与挤塑板相邻的功能层与挤塑板存在不同的膨胀系数而导致气温变化时复合保温板功能层的剥离或断裂，在复合保温板中添加C型钢，以增强复合保温板的强度，C型钢的底边与挤塑板连接，C型钢的两侧分别设置在第一微发泡加聚苯颗粒层、第二微发泡加聚苯颗粒层，可以进一步防止因与挤塑板相邻的功能层与挤塑板存在不同的膨胀系数而导致气温变化时复合保温板功能层的剥离或断裂
A large composite thermal insulation board of steel structure extruded board is composed of extruded board as the main thermal insulation material, and trapezoidal connection grooves are arranged on the extruded board to prevent the peeling or fracture of the functional layer of the composite thermal insulation board when the temperature changes due to the different expansion coefficients between the functional layer adjacent to the extruded board and the extruded board. C-section steel is added to enhance the strength of composite insulation board. The bottom edge of C-section steel is connected with the extrusion board. The two sides of C-section steel are respectively arranged in the first micro-foamed polyphenyl granular layer and the second micro-foamed polyphenyl granular layer, which can further prevent the different expansion coefficients between the functional layer adjacent to the Extrusion board and the extrusion board. Peeling or Fracture of Functional Layer of Composite Thermal Insulation Plate under Temperature Change
此外，钢结构挤塑板复合保温板还设置有玻璃纤维层、钢丝网层，钢丝网层可以加强复合保温板的强度，玻璃纤维层可以加强复合保温板的防水性、耐腐蚀性。
In addition, the composite insulation board of steel structure extruded board is also equipped with glass fiber layer and steel wire mesh layer. The steel wire mesh layer can strengthen the strength of the composite insulation board, and the glass fiber layer can strengthen the waterproof and corrosion resistance of the composite insulation board.
