RIGID FOAM INSULATION HAVING A TONGUE-AND-GROOVE COUPLING

An insulating member comprises a body of rigid foam material having a first connecting edge surface and a second connecting edge surface， a groove formed into the rigid foam material of the body along the first connecting edge surface， and a tongue formed from the rigid foam material of the body along the second connecting edge surface. The groove， when viewed in a transverse cross-section， tapers from narrow to wide in a direction extending from its opening and into the body. The tongue， when viewed in a transverse cross-section. tapers from wide to narrow in a direction toward the second connecting edge surface. The tongue is bifurcated along its length into first and second ridges by a wedge-shaped void. A polymer coating of polyurea or polyurethane substantially covers the tongue and structurally reinforces the tongue allowing the first and second ridges to flex toward one another without breaking.一种绝缘构件，包括由硬质泡沫材料（rigid foam material）制成的本体，该本体设有第一连接边缘面与第二连接边缘面；沿第一连接边缘面开设于本体质硬质泡沫材料中的凹槽，以及沿第二连接边缘面由本体质硬质泡沫材料形成的凸舌。该凹槽在横向截面视角下，自其开口朝向本体内延伸的方向上，呈由窄至宽的渐扩锥度。该凸舌在横向截面视角下，朝向第二连接边缘面的方向上，呈由宽至窄的渐缩锥度。该凸舌沿其长度方向被一楔形空隙分隔为第一棱脊与第二棱脊。一层由聚脲（polyurea）或聚氨酯（polyurethane）制成的聚合物涂层基本覆盖于凸舌表面，并对凸舌形成结构增强作用，使得第一棱脊与第二棱脊能够相互靠拢弯折而不会发生断裂。
