The embedded steel plates 1 and the embedded parts 2 are used for forming an embedded structure on an external mounting structure and providing fixing points for the end portions of the steel beams. The embedded part 2 can generally adopt L shaped steel muscle to replace, and the one end and the embedded steel sheet 1 fixed connection of embedded part 2, inside the concrete of the external installation structure of other end embedding, make embedded steel sheet 1 with the laminating of the vertically form of face be fixed in external installation structure's concrete surface. The embedded structure can be embedded in a reinforcement cage in advance before concrete of the external mounting structure is poured, and can be combined with the external mounting structure into a whole after subsequent concrete is poured. However, it should be noted that the outer surface of the embedded steel plate 1 needs to protrude out of the concrete surface of the external mounting structure, so as to facilitate the subsequent welding operation.
In consideration of the stability of the embedded structure, a plurality of embedded parts 2 can be uniformly distributed on the embedded steel plate 1, and 4 embedded parts 2 are shown in the figure and are respectively positioned at four corners of the embedded steel plate 1.
In the utility model, the temporary supporting function provided by the embedded structure is realized by the two triangular supporting plates 3, the two triangular supporting plates 3 are fixed on the outer surface of the embedded steel plate 1, and the specific positions of the two triangular supporting plates 3 are determined according to the lap joint position of the web plate of the H-shaped steel beam 5 to be installed subsequently. The two triangular support plates 3 are fixed on two sides of the lap joint position of the web plate of the H-shaped steel beam 5 and the embedded steel plate 1. The two triangular support plates 3 are both right-angled triangular steel plates which are provided with two right-angled sides. One right-angle side of each triangular support plate 3 is welded and fixed with the outer surface of the embedded steel plate 1, the other right-angle side is kept horizontal, the elevations of the horizontal right-angle sides of the two triangular support plates 3 are the same, and the two right-angle sides are respectively used for supporting the upper flanges of the two sides of the external H-shaped steel beam 5. H shaped steel roof beam 5 is in hoist and mount in-process, and the web of its tip inserts between two triangular support board 3, and the both sides top flange can interim overlap joint at the horizontal right angle edge of two triangular support board 3, need not welding process and can form interim load-carrying structure.
Although the elevations of the horizontal right-angle sides of the two triangular support plates 3 are the same, the height adjusting gaskets 4 are placed on the horizontal right-angle sides of the triangular support plates 3 to solve the problem in consideration of inevitable error factors in the field construction process and machining error factors of the H-shaped steel beam 5, and the top flanges on the two sides of the H-shaped steel beam 5 still can not be attached to the top sides of the two triangular support plates 3 in the hoisting process.
