Plate and bolt and nut connect, described diamond plate steel truss along the Vierendeel girder side arrangement of concrete frame intercolumniation,
And it being welded into entirety with the angle steel of Vierendeel girder lower end, butted part reserves link bolt hole.
Further, joint anchorage steel plate reinforcement is passed through at described concrete frame beam and frame column node.
Further, described concrete frame beam lower end is additionally provided with ribbed stiffener.
Further, described predetermined pattern slab plate thickness is 3～20mm, and width is 10～50mm, with water
Horizontal line angle is 45 °, is interweaved into latticed, and upper/lower terminal reserves bolted band hole respectively
End plate.
Further, described predetermined pattern slab plate is along the elongated layout in Vierendeel girder side, or along Vierendeel girder side
Face is arranged near the two ends of frame column.
Described is dabbing layer to concrete frame beam periphery, and its dabbing degree of depth is 5～10mm, between dabbing trace
Away from for 10～30mm.
The invention have the benefit that
1. the present invention is as the structure of building concrete beam, draws materials conveniently, makes simple possible, overall
Performance is good, applied range, and economic benefit is good.
2. the present invention is the form of external prefabricated reinforced beams of concrete, breaks for beams of concrete self structure
Bad degree is less, forms one with original concrete frame beam, and overall performance is good.
3. the present invention uses the stiffness by itself of former concrete frame beam, the spy high with concrete crushing strength
Point, plays the feature that predetermined pattern slab truss intensity is high, improves the shearing resistance of former concrete frame beam, resists
Curved ability, both bring out the best in each other.
