Example one

The invention discloses a fire fighting pipeline erecting mechanism applied to a single-layer spherical net rack steel structure as shown in figures 1-2, which comprises a steel structure combination arranged on a workshop ceiling and an auxiliary connecting piece fixedly erecting a fire fighting pipeline 1 together with the steel structure combination. The steel structure combination includes spherical node 13 and bracing piece 4, and spherical node 13 is a plurality of, and a plurality of spherical nodes are set for the distance at the ceiling interval of filling station and are arranged, 6 screw holes of surface processing of spherical node, bracing piece 4 through threaded connection in every screw hole, and the bracing piece of adjacent spherical node passes through connecting rod and relevant structure interconnect and becomes a whole. The spherical node and the supporting rod are manufactured by machining after the quenching and tempering of 45 steel, the hardness of a workpiece is HB 240 plus 270, the outer surface is subjected to anti-corrosion treatment, the surface is required to be smooth and free of burrs after the surface machining, and the surface roughness is recommended to be 12.5 mu m or below.

Every spherical node top all is connected with a supporting sleeve, at supporting sleeve top erection joint backup pad 3, can be in advance at the mill with the supporting sleeve lower extreme with spherical node welding firm, supporting sleeve upper end and backup pad welding firm, then transport the assembly scene of filling station, backup pad 3 is diameter 300 mm's circular steel sheet, the fire control pipeline transversely places in the top of a plurality of backup pads, it is fixed with backup pad 3 through clamping ring 2, places and falls. The clamping ring 2 is an inverted U-shaped structure formed by processing reinforcing steel bars or round steel bars through a bending machine, threaded screw rods are processed at two ends of the inverted U-shaped structure, and the screw rods penetrate through the supporting plate 3 and are fastened through second nuts 9. The arc part of the inverted U-shaped structure and the support plate are combined to form a closed space, and the fire fighting pipeline is extruded and fixed in the closed space.

For further reinforcing fixed fastness, set up four connecting blocks 8 at the lower surface of backup pad, this connecting block can weld in the backup pad lower surface in the lump when welding the support sleeve can, every connecting block all processes horizontal through-hole, and wherein one end of pull rod 7 is fixed with the nut after running through this through-hole, and the other end and the trompil ring 6 of pull rod 7 are connected. The split ring 6 is sleeved outside the support rod 4, the two ends of the opening of the split ring are provided with connecting end plates, each connecting end plate is provided with a through hole, the pull rod is inserted between the two connecting end plates, the through hole of the rear pull rod is coaxial with the through holes of the two connecting end plates, the screw and nut combination 5 is screwed after being inserted into the through holes, the support rod is tightly held by the split ring, and the position of the pull rod is firmly fixed.

The split ring, the pull rod and the compression ring are processed by 45 steel and then are subjected to quenching and tempering treatment, the hardness is kept at HRC50-55, after the processing is finished, all parts are chamfered into acute angles, the surfaces are smooth and have no burrs or flashes, and the surfaces are subjected to bluing treatment or are plated with an anticorrosive coating. When the four pull rods and the connecting block are screwed, the four pull rods and the connecting block need to be screwed up in a crossed, symmetrical, gradual and uniform manner.

Example two

In this embodiment, only the connection manner of the support plate and the pull rod is different, and the rest of the structure is the same as that of the first embodiment. The connected mode of lug connection is chooseed for use to the backup pad with the connected mode of pull rod, it has a plurality of through-holes that run through to be in backup pad 3 promptly, the through-hole of lower surface, the axis in hole is the setting angle slope setting with vertical plane, this through-hole is the hole of all inclining in vertical plane and horizontal plane promptly, pull rod 7 is fixed with second nut 9 and backup pad after running through this through-hole, this kind of connected mode utilizes the effect of bracing piece 4 to decompose the power of pull rod into vertical ascending holding power and the outside pulling force of level, the support of auxiliary stay board to the fire control pipeline, can improve stability, alleviate the heavy burden of backup pad, the whole fastness of reinforcing device.

EXAMPLE III

In this embodiment, only the connection manner of the support plate and the pull rod is different, and the rest of the structure is the same as that of the first embodiment.
