Description

Technical Field

[0001] The utility model relates to the field of fire protection pipelines, in particular to a pipeline riser load-bearing short section. Background Art

[0002] Fire-fighting pipes can be divided into risers and horizontal pipes according to their placement. The horizontal pipes are supported by fixed frames, while in the risers, the fixed frames can only play a fixing role in the horizontal direction. The force concentration points of the risers and the weight of the water inside them are mainly shared at the joints of the risers, the matching points of the risers and the floor slabs, and the connections between the risers and the horizontal pipes. This causes the joints of the risers and the connections between the risers and the horizontal pipes to become loose and disconnected, and the matching points between the risers and the floor slabs to become loose and cracked, resulting in water leakage, especially for large-diameter pipes. In addition, as the number of building floors increases, the risers are also set higher and more, and the weight is also heavier, which will further aggravate the above situation.
