We develop a technique for the construction of integrable models with a ℤ2 grading of both the auxiliary (chain) and quantum (time) spaces. These models have a staggered disposition of the anisotropy parameter. The corresponding Yang-Baxter equations are written down and their solution for the gl(N) case is found. We analyze in details the N = 2 case and find the corresponding quantum group behind this solution. It can be regarded as the quantum group UqB(gl(2)), with a matrix deformation parameter qB such that (qB)2 = q2. The symmetry behind these models can also be interpreted as the tensor product of the (-1)-Weyl algebra by an extension of Uq(gl(N)) with a Cartan generator related to deformation parameter -1.
