Concealed prestressed wood beam
The invention discloses a concealed prestressed wood beam, which comprises a wood beam, one or more prestressed tendons, steering devices and anchoring devices, wherein the wood beam is a coupled beam, and cushion blocks between beams, a cushion block at an anchoring end, and bolts are arranged between two parallel beams which are connected to form a whole body; the one or more prestressed tendons are arranged in a middle gap of the coupled beam, and the two ends of the prestressed tendons are anchored at the beam end, on a column body or between the beams by the anchoring device; the middle part of each prestressed tendon is fixedly arranged in the middle of the coupled beam by the corresponding steering device, and each steering device comprises a pin shaft and a gluing steel plate; each gluing steel plate is fixedly arranged in a wood beam body or adhered to the inner side of the wood beam by adhesive resin, and each pin shaft passes through a pin shaft hole in the corresponding gluing steel plate and is transversely arranged in the middle gap of the coupled beam. The concealed prestressed wood beam provided by the invention has the advantages of high bearing capacity, light self weight, good fireproof performance, simple system, attractive appearance, industrial production, and quick installation. The concealed prestressed wood beam provided by the invention can be used in the fields of structures such as large-span buildings and bridges.
