Steel roof truss top chord angle iron and top chord horizontal support connecting structure and method
The invention relates to the construction engineering structure field, and specifically relates to a steel roof truss top chord angle iron and top chord horizontal support connecting structure and method. The bottom and the side face of an original steel roof truss top chord angle iron are all welded with a newly-added angle iron, and a rectangle or square 'mouth' shape is formed between two sides of the newly-added angle iron and the original steel roof truss top chord angle iron; an original roof top chord horizontal support node plate is cut off, and an original roof top chord horizontal support angle iron on the original roof top chord horizontal support node plate is used as a horizontal support angle iron and moves down; one end of a newly-added horizontal support node plate is welded on the bottom face of the newly-added angle iron, and the bottom face of the other end of the newly-added horizontal support node plate is provided with the horizontal support angle iron through bolts. The structure is mainly used for reinforced concrete row-frame factory workshops, a roof is a trapezoidal steel roof truss (or light roof trapezoidal steel roof truss and the like), a steel purlin and a single-layer pressed steel plate composite heat preservation roof (or a single-layer pressed steel plate composite heat preservation and heat insulation roof), and the durability and the heat preservation effect of the original roof are improved.
