7. The prestressed wood-structured house according to claim 6, wherein said house has at least two stories, the upper and lower adjacent prestressed wall slabs are connected by a floor slab, and one end of said first prestressed wire connecting member connected to said prefabricated wood truss roof is connected to one end of said second prestressed wire connecting member connected to said floor slab by a third prestressed wire connecting member.
8. The prestressed wood-structured house according to claim 7, wherein said first prestressed wire-connecting members comprise two metal rings fastened to each other, and said third prestressed wire-connecting members comprise an open-hole metal circular plate and prestressed wires disposed around the metal circular plate and tied to the metal circular plate.
9. The prestressed wood-structured house as claimed in claim 1, wherein steel plates are coated on the surfaces of the prestressed wallboards, the horizontal connector units are connected to the steel plates in an anchored manner, and fixing means for fixing the transverse reinforcing bars are provided in the prestressed wallboards.
10. The assembling method of the pre-stressed wood-structure house according to any one of claims 1 to 9, the method is characterized in that three prestressed walling boards are fixed, steel plates are covered on one prestressed wallboard and horizontal prestressed steel bars are applied, then steel plates are covered on the other three prestressed walling boards and the horizontal prestressed steel bars are anchored, after the four prestressed walling boards are fixed, a floor slab is laid at the top end of the prestressed wallboard, after the floor slab is laid, anchoring vertical prestressed reinforcements on the prestressed wallboard, assembling a pressure jacking supporting device between the prestressed wallboard and the upper floor slab, the four prestressed wallboards are anchored on the upper surface of the floor slab by the fixing method to serve as an upper layer structure, then a second prestressed anchorage device and a connecting assembly are additionally arranged outside the prestressed wallboards to form a K-shaped structure, and finally the prefabricated wood truss roof, the floor slab and the lawn are tied to form the integral beam-column-free prestressed wood structure house.
