Embodiment 1
[0037] Such as Figure 1-8 Shown: a prestressed double glued wood beam, including wooden beam main body 1, prestressed tendon 2, steering device 3, anchorage 4, steel pad 5, anchor pad 6, beam end pad 7, span Pad block 8 and self-tapping screw 9, described wooden beam main body 1 is a double-joint beam, and the double-split beam is connected as a whole by beam end pad 7 and span pad 8 arranged at intervals along the full length of the component, and beam end pad 7, The spacer 8 is connected with the wooden beam main body 1 by fixing the spacer bolt 15 . The prestressed tendons are set 2 in the middle gap of the double-split beam, and the two ends of the prestressed tendons 2 are anchored to the beam end through the anchor 4 and the anchor backing plate 6, and the beam end is provided with a beam for anchoring the anchor backing plate. The end screw hole 10 and the prestressed tendon hole 11 are reserved at the beam end, the anchor backing plate 6 is provided with the anchor b...
Embodiment 2
[0039] Such as Figure 7-9 As shown, the difference between this embodiment and Embodiment 1 is that: the wooden beam main body 1 is a box-shaped beam, and the prestressed tendons 2 are arranged in the hollow space of the box-shaped beam.
Embodiment 3
[0041] Such as Figure 10-12 As shown, the difference between this embodiment and Embodiment 1 is that the supporting body 3-1 of the steering device 3 is rectangular.
