Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall fall within the protection scope of the present invention.

Examples

The utility model provides a roof structure of encorbelmenting of bucket arch form, the structure of should encorbelmenting includes that the horizontal rectangle steel pipe of multilayer is crisscross from top to bottom arranges and forms, and the nodical position of multilayer rectangle steel pipe plane projection is connected through vertical jib. Each layer of horizontally arranged rectangular steel pipes are gradually reduced in the overhanging depth direction, namely the overhanging length of the horizontal rectangular steel pipe at the highest layer is the largest, and the overhanging length of the rectangular steel pipe arranged towards the lower layer is smaller. After the installation of the multilayer horizontal structure is completed, the appearance of the building with the arched bucket can be formed only by the anticorrosion and fireproof coating treatment on the surface of the structure.

As shown in fig. 1, the roof overhanging structure in the form of an arch mainly includes multiple layers of horizontal rectangular steel pipes 100 and vertical suspenders 200 arranged in an up-down staggered manner. The crossing point position of crisscross plane projection of horizontal rectangle steel pipe 100 connects vertical jib 200, and the two forms the structure of encorbelmenting after connecting, and indoor steel tubular construction 300 sets up at horizontal rectangle steel pipe 100, the root of the structure of encorbelmenting after vertical jib 200 connects (being the tail end of rectangle horizontal steel pipe 100, being close to indoor one side), and indoor steel tubular construction 300 is striden for the structure of encorbelmenting provides the structure back seat, and its structure can be according to roof molding and structural rationality select rigid structure such as truss or rack. The top end of the vertical suspender 200 is connected to the lower flange of the horizontal rectangular steel pipe on the upper layer, and the bottom end is connected to the upper flange of the horizontal rectangular steel pipe on the lower layer. The indoor steel pipe structure 300 is preferably connected to the root of the rectangular horizontal steel pipe 100 by welding.

The vertical hanger rods 200 are rectangular steel pipes, the width of the cross sections of the vertical hanger rods is the same as that of the cross sections of the horizontal rectangular steel pipes 100 which are arranged in a staggered mode, and the horizontal rectangular steel pipes 100 which are arranged in a staggered mode are connected with the vertical hanger rods 200 in a welding mode. Preferably, the distance between the horizontal rectangular steel pipes 100 of each floor is about 1m, and the distance between the hanger rods of the vertical hanger rods 200 is about 1.5 m.

As shown in fig. 2, the overhanging structure is surrounded around the indoor steel pipe structure 300, and overhangs towards the outdoor direction with the upright of the indoor steel pipe structure 300 as the starting point, it can be seen that the horizontal rectangular steel pipes 100 horizontally staggered are vertically arranged in two directions, and the intersection point position of the steel pipes in the two directions is the position of the vertical suspension rod 200.

As shown in fig. 3, the horizontally arranged horizontal rectangular steel pipes 100 are arranged in a staggered manner in the height direction, that is, the upper horizontal rods are in the X direction, the lower horizontal rods are in the Y direction, and the vertical hanger rods 200 are arranged at the positions of the projection intersections of the two layers of horizontally rectangular steel pipes 100 arranged in a crossed manner in the vertical direction. It can be seen from the figure that in the overhanging direction, the overhanging length of the uppermost horizontal rectangular steel tube 100 is the longest, and the overhanging length decreases layer by layer downward.

As shown in fig. 4, when the vertical hanger bar 200 is connected to the horizontally arranged horizontal rectangular steel pipe 100, the two horizontal rectangular steel pipes may be directly connected by welding at the joint because the widths of the two horizontal rectangular steel pipes are the same, and in order to increase the rigidity of the joint area, two triangular armboards 101 may be provided at each side of the joint. Meanwhile, in order to reinforce the welding seams of the hanger rods and the horizontal rods on the parallel sides, after the welding is finished and the welding seams are polished at the position, a steel plate 102 is welded on the outer layer of the node in a repair mode, and meanwhile, the section strength and rigidity of the vertical hanger rods 200 are increased by increasing the thickness of the rod wall of the vertical hanger rods, so that the vertical load can be transmitted from the upper layer to the lower layer through the node.

The structure integral installation can form the building structure of encorbelmenting of bracket form after accomplishing, later need carry out anticorrosive and fire prevention coating treatment on each steel construction surface.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
