It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1

As shown in figure 1, a global displacement isolation pipe for building electromechanical pipelines is used as a flexible pipeline connecting section and is installed in a certain public building shock insulation layer, and the displacement response of an isolation upper structure damages the electromechanical pipeline system.

The universal displacement isolating pipe for the building electromechanical pipeline of the embodiment has a right-angle trend in orthographic projection on a horizontal plane XY, and the whole isolating pipe comprises the following components from the upper end to the lower end: j-shaped trigger tube 1, displacement bellows 2 and fixed stop tube 3. The displacement corrugated pipe 2 is formed by sequentially connecting 4 sections of corrugated pipes 201 at intervals through a jumper pipe I202, a transition bend 203 and a jumper pipe II 204, the transition bend 203 in the middle is a 90-degree bent pipe, each section of corrugated pipe 201 is provided with a pair of hinges 205 in an up-and-down symmetrical mode, each hinge 205 comprises an outer hinge plate 2051, an inner hinge plate 2052 and a pin shaft 2053, and all the pin shafts 2053 are perpendicular to a horizontal plane XY where the axes of the displacement corrugated pipes 2 are located. As shown in fig. 4, the inner hinge plates 2052 of the 2-segment corrugated pipe 201 connected by the jumper pipe i 202 are split and are arranged symmetrically up and down and left and right along the jumper pipe i 202. The inner hinge plates 2052 of the 2-section corrugated pipe 201 connected by the jumper pipe II 204 are also split and are symmetrically arranged up and down and left and right along the jumper pipe II 204. The distance between the two pairs of pin shafts 2053 at the two ends of the jumper tube I202 along the axis of the jumper tube I202 is equal to the distance between the two pairs of pin shafts 2053 at the two ends of the jumper tube II 204 along the axis of the jumper tube II 204. The outer surfaces of the J-shaped trigger pipe 1, the deflection corrugated pipe 2 and the fixed stop pipe 3 are respectively covered with a fireproof layer.

In the example, a straight pipe section of a J-shaped trigger pipe 1 penetrates into a seismic isolation layer from the lower part of an upper floor 4 of the seismic isolation layer, a bent pipe section turns for 90 degrees, and the axis of the J-shaped trigger pipe 1 turns to the horizontal plane Y along the vertical direction Z to be connected with a displacement corrugated pipe 2 positioned in the horizontal plane XY; further, the transition bend is a 90-degree bend, and the tube turns from-Y to + X along the axis; the fixed stop pipe 3 of the embodiment is also J-shaped, the 90-degree bent pipe end of the fixed stop pipe is connected with the deflection corrugated pipe 2, and the straight pipe end of the fixed stop pipe penetrates through the lower floor 5 of the seismic isolation layer to enter the basement.

The universe displacement isolation tube for the building electromechanical pipeline can isolate seismic displacement response input by an upper structure through the J-shaped trigger tube 1 by using isotropic maximum displacement capacity during an earthquake, and is characterized in that the universe displacement isolation tube for the building electromechanical pipeline is always synchronously and flexibly deformed in real time by virtue of translation displacement of all directions randomly switched by an adaptive structure, so that strain of all positions of the pipeline is eliminated in real time, and the stress of all the positions is always qualified.

The whole isolation pipe for the building electromechanical pipeline in the embodiment has an obtuse angle trend in the orthographic projection of the whole isolation pipe on a horizontal plane XY, and comprises the following components from the upper end to the lower end: j-shaped trigger tube 1, displacement bellows 2 and fixed stop tube 3. The displacement corrugated pipe 2 is formed by sequentially connecting 4 sections of corrugated pipes 201 at intervals through a jumper pipe I202, a transition bend 203 and a jumper pipe II 204, the transition bend positioned in the middle is a 135-degree bent pipe, each section of corrugated pipe 201 is vertically and symmetrically provided with a pair of hinges 205, each hinge 205 comprises an outer hinge plate 2051, an inner hinge plate 2052 and a pin shaft 2053, and all the pin shafts 2053 are perpendicular to the horizontal plane XY where the axes of the displacement corrugated pipes are positioned. As shown in fig. 4, the inner hinge plates 2052 of the 2-segment corrugated pipe 201 connected by the jumper pipe i 202 are split and are symmetrically arranged up and down and left and right along the jumper pipe i 202.
