I recently had a need for these functions. I wrote a quick method (below) for my particular case, but I would be better if they were officially supported.

function Base.hcat(x::Zeros{T,2}...) where T <: Real
    all(xx -> xx.size[1] == x[1].size[1], x) || throw(ArgumentError("mismatch in dimension 1"))
    n = sum(xx.size[2] for xx in x)

    return Zeros(x[1].size[1],n)
end
