The utility model relates to a paint wall board insect proof gasket, which is suitable for being tightly clamped between a wave shaped steel plate and a crossbeam. The wave shaped steel plate comprises a plurality of fixed sections, extension sections and concave sections which are convex bending along a long direction. The crossbeam comprises a fixed wall which extends along the long direction and can withstand the fixed sections, two adjacent concave sections, corresponding extension sections and corresponding fixed wall matching. An accommodation space is defined, and the insect proof gasket of the paint wall panel comprises a gasket body.The gasket body includes a first top butting surface, a second top butting surface, and two sealing surfaces respectively connecting the first top butting surface and the second top butting surface.The gasket body can be tightly fitted between the wave shaped steel plate and the crossbeam and completely filled in the holding space, so as to avoid the breeding of insects and other organisms and achieve the effect of insect prevention.一種烤漆牆板防蟲墊片，適用於緊配合地夾設在一浪型鋼板與一橫樑間，該浪型鋼板包括複數沿一長方向凹凸彎折的固定段、延伸段，及凹陷段，該橫樑包括一沿該長方向延伸且能頂抵該等固定段的固定壁，相鄰兩凹陷段、相對應的延伸段，及相對應的固定壁配合界定出一容置空間，該烤漆牆板防蟲墊片包含一墊片本體。該墊片本體包括一第一頂抵面、一第二頂抵面，及二分別連接該第一頂抵面與該第二頂抵面的密合面。該墊片本體能緊配合地套塞於該浪型鋼板與該橫樑間並完全填充於該容置空間，避免昆蟲等生物孳生，達到防蟲的效果。
