Detailed Description

In order to make the technical scheme of the present application better understood by those skilled in the art, the present application will be further described in detail with reference to the accompanying drawings.

Referring to fig. 1-2, an embodiment of the present application discloses a pipe hanger with damping diagonal braces for use in achieving a lifting support of a pipe system 40 on a main structure. The main body structure may be a large span hinge structure, such as a bridge structure. The main structure comprises a first beam body 30 and a second beam body 50, and the pipeline support and hanger is based on the first beam body 30 and the second beam body 50, so that the hoisting support of the pipeline system 40 is realized.

The pipeline support and hanger with the damping diagonal braces disclosed by the embodiment of the application comprises a vertical hanger 10 and the damping diagonal braces 20. The vertical hanger 10 is a main body member of a pipe hanger extending in a vertical direction so as to hang the pipe system 40 directly under the first girder 30. Specifically, a first end of vertical hanger 10 is connected to first beam 30 and a second end of vertical hanger 10 is connected to ductwork 40. The vertical hanger 10 can alleviate the impact of the pipe system 40 in the vertical direction during the earthquake. The vertical hanger 10 can be a frame body with higher strength.

The damping shock absorbing diagonal braces 20 are disposed obliquely with respect to the vertical hanger 10. Specifically, the included angle between the damping diagonal strut 20 and the vertical hanger 10 may be 35-55 °. Alternatively, the angle between the damping strut 20 and the vertical hanger 10 may be 45 °.

Of course, the damping strut 20 can also connect the conduit system 40 to the main structure, thereby providing support of the conduit system 40 relative to the main structure in an oblique direction. Specifically, a first end of the damping vibration attenuation brace 20 is connected to the second beam 50 and a second end of the damping vibration attenuation brace 20 is connected to the piping system 40. The pipe system 40 is suspended below the main structure by the cooperation of the vertical hanger 10 and the damping diagonal brace 20, thereby realizing the installation. The damping and shock absorbing diagonal braces 20 can mitigate the seismic impact experienced by the pipe system 40 in the horizontal direction.

Optionally, the first beam 30 and the second beam 50 are positioned in the same straight line, so that the pipeline support hanger is ensured to act in the same plane, the pipeline support hanger is prevented from being twisted in the installation process, and the influence of initial stress is reduced.

In the embodiment of the present application, the damping and shock absorbing diagonal brace 20 includes a first sleeve 21, a support rod 22, and a second sleeve 23.

The first end of the first sleeve 21 is connected to the second beam 50, the second end of the first sleeve 21 is sleeved on the first end of the supporting rod 22, and the first end of the supporting rod 22 is slidably matched with the second end of the first sleeve 21, so that the first sleeve 21 and the supporting rod 22 can slide relatively. The second end of the first sleeve 21 forms a first shock absorbing cavity 24 with the first end of the support rod 22. The first damping elastic member 26 is disposed in the first damping cavity 24, and when the second end of the first sleeve 21 and the first end of the supporting rod 22 slide relatively, the first damping elastic member 26 can elastically deform in a telescopic manner, so that the first sleeve 21 and the supporting rod 22 absorb the impact of an earthquake. Alternatively, the first shock absorbing elastic member 26 may be a member capable of elastic expansion and contraction deformation of the first spring, the first rubber column, or the like, and the embodiment of the present application is not limited to the specific kind of the first shock absorbing elastic member 26.

The first end of the second sleeve 23 is connected with the pipeline system 40, the second end of the second sleeve 23 is sleeved on the second end of the supporting rod 22, the second end of the supporting rod 22 is in sliding fit with the second sleeve 23, the second sleeve 23 and the supporting rod 22 can slide relatively, a second damping cavity 25 is formed by the second sleeve 23 and the second end of the supporting rod 22, a second damping elastic piece 27 is arranged in the second damping cavity 25, and under the condition that the second end of the second sleeve 23 and the second end of the supporting rod 22 slide relatively, the second damping elastic piece 27 can elastically stretch and deform, so that the second sleeve 23 and the supporting rod 22 can absorb earthquake impact. Similarly, alternatively, the second shock absorbing elastic member 27 may be a member capable of elastic expansion and contraction deformation, such as a second spring, a second rubber column, or the like, and the embodiment of the present application is not limited to the specific kind of the second shock absorbing elastic member 27.

In the pipeline support and hanger disclosed by the embodiment of the application, the vertical hanger 10 and the damping and shock-absorbing diagonal brace 20 can play a synergistic effect, so that the pipeline system 40 is hoisted on a main structure. Meanwhile, the vertical hanger 10 can assist the pipe system 40 to bear the impact of an earthquake in the vertical direction, the damping shock absorbing diagonal brace 20 can bear the sliding of the supporting rod 22 relative to the first sleeve 21 and the second sleeve 23 under the condition that the external force is applied in the earthquake process, and then the elastic expansion and contraction deformation of the first shock absorbing elastic piece 26 in the first shock absorbing cavity 24 and the elastic expansion and contraction deformation of the second shock absorbing elastic piece 27 in the second shock absorbing cavity 25 are respectively carried out, and then the damping shock absorbing diagonal brace 20 is enabled to be integrally expanded and contracted, so that the damping is generated to buffer the impact of the pipe system 40 in the earthquake process, and the damping shock absorbing diagonal brace 20 is obliquely arranged, so that the pipe system 40 can be better supported under the impact of the earthquake in the vertical direction and the horizontal direction, and the effect of better supporting the pipe system 40 is achieved, and the pipe system 40 is not easy to damage in the earthquake is avoided.

Through verification, the pipeline supporting and hanging frame disclosed by the embodiment of the application can well absorb shock of a pipeline system, and finally can reduce the damage of a large-span pivot structure in an earthquake.

As described above, the first and second shock absorbing elastic members 26 and 27 achieve a damping effect by elastic expansion and contraction deformation of themselves. In order to further improve the damping effect, in a preferred embodiment, the first and second shock absorbing chambers 24 and 25 may be filled with hydraulic oil. In the process of bearing the earthquake impact, the hydraulic oil can exert better damping effect under the pressure, so as to better buffer the impact of the earthquake.

Optionally, the first end of the first sleeve 21 and the first end of the second sleeve 23 are closed ends. The second end of the first sleeve 21 and the second end of the second sleeve 23 may each be provided with an oil seal 28. Since the first and second damper chambers 24 and 25 may be filled with hydraulic oil. Therefore, by providing the oil seal structure 28 at the second end of the first sleeve 21, leakage of hydraulic oil between the second end of the first sleeve 21 and the first end of the support rod 22 can be well avoided. Similarly, by arranging the oil seal structure 28 at the second end of the second sleeve 23, hydraulic oil leakage between the second end of the second sleeve 23 and the second end of the supporting rod 22 can be well avoided.

In a further technical solution, a sponge tube 29 is connected to a side of the oil seal structure 28 away from the first shock absorbing cavity 24 or the second shock absorbing cavity 25, and the sponge tube 29 is sleeved on the support rod 22. That is, there are two sponge cylinders 29, one disposed near the oil seal 28 corresponding to the first damper chamber 24, and on the side of the oil seal 28 away from the first damper chamber 24; the other is arranged near the corresponding oil seal structure 28 of the second shock absorption cavity 25 and is positioned at the position, away from the corresponding oil seal structure 28 of the second shock absorption cavity 25, of the oil seal structure 28. In the course of the work, in case hydraulic oil leakage takes place, the sponge barrel 29 can play the effect of quick absorption, avoids hydraulic oil to flow out.

As described above, in the actual working process, the hydraulic oil exerts a good damping effect, so that the hydraulic oil is prevented from being excessively compressed. In one embodiment, the first sleeve 21 and the second sleeve 23 may each include an inner tube and an outer tube, the inner tube is sleeved inside the outer tube, and an oil temporary storage space is formed between the inner tube and the outer tube, that is, an oil temporary storage space can be formed between the inner tube and the outer tube.

Specifically, the inner tube of the first sleeve 21 and the support rod 22 form a first damping cavity 24, the inner tube of the first sleeve 21 is in sliding fit with the support rod 22, so that sliding fit between the first sleeve 21 and the support rod 22 is achieved, the inner tube of the second sleeve 23 and the support rod 22 form a second damping cavity 25, and the inner tube of the second sleeve 23 is in sliding fit with the support rod 22, so that sliding fit between the second sleeve 23 and the support rod 22 is achieved. The inner tube is provided with an oil passing hole through which the first damping cavity 24 or the second damping cavity 25 is communicated with the temporary oil storage space.

That is, at least part of the structures of the first sleeve 21 and the second sleeve 23 may be the same, the inner tube and the outer tube included in the first sleeve 21 may form one temporary oil storage space (i.e., the first temporary oil storage space) that communicates with the first shock absorbing chamber 24 through the oil passing hole (i.e., the first oil passing hole) on the inner tube, and the inner tube and the outer tube included in the second sleeve 22 may form another temporary oil storage space (i.e., the second temporary oil storage space) that communicates with the second shock absorbing chamber 25 through the oil passing hole (i.e., the second oil passing hole) on the inner tube. Thus, when the damping diagonal bracing 20 receives the earthquake impact, the hydraulic oil is extruded, and further more hydraulic oil can enter the temporary oil storage space through the corresponding oil passing holes, and when the damping diagonal bracing is to be elastically restored, the hydraulic oil can flow back to the first damping cavity 24 or the second damping cavity 25 through the corresponding oil passing holes. Of course, the oil passing hole can comprise an oil inlet hole and an oil outlet hole, hydraulic oil can enter the temporary oil storage space through the oil outlet hole, and the hydraulic oil can flow back to the temporary oil storage space through the oil inlet hole. The structure can avoid the excessive extrusion of hydraulic oil in the earthquake process to cause the sealing structure to bear excessive sealing pressure.

In an embodiment of the application, the first sleeve 21 and/or the second sleeve 23 may be provided with threaded holes (not shown). The threaded bore is provided with a threaded connection 210, which may be a bolt, screw, stud, etc., and the threaded connection 210 is fixedly connected to the second beam 50 or the pipe system 40. That is, in the case where the first sleeve 21 is provided with a screw hole, the screw connector 210 engaged with the screw hole is fixedly coupled to the second beam 50. In the case where the second sleeve 23 is provided with a threaded hole, the threaded connector 210, which cooperates with the threaded hole, is fixedly connected to the pipe system 40. In this case, the threaded connection 210 is in threaded engagement with the threaded hole, and before installation, the length of the damping and shock-absorbing diagonal brace 20 can be adjusted by rotating the depth of the threaded connection 210 screwed into the threaded hole, so that the distance between the pipe system 40 and the second beam 50 can be flexibly adapted.

Referring again to fig. 1, in an embodiment of the present application, both the first beam 30 and the second beam 50 may be i-beams, and the first end of the vertical hanger 10 may be fixedly connected to the first channel 60, for example, the first end of the vertical hanger 10 may be welded to the first channel 60. The first channel 60 may be detachably clamped to the first beam 30 by two first clamps 61, thereby achieving a connection between the first end of the vertical hanger 10 and the first beam 30.

Similarly, the first end of the damping strut 20 is fixedly connected to the second channel 70, and likewise, the two may be welded together. The second channel 70 is detachably clamped to the second beam 50 by two second clamps 71. The above-mentioned mode of realizing dismantling the fixed through first anchor clamps 61 or second anchor clamps 71 certainly is convenient to overhaul and the dismantlement of partial component is changed, and the operation is also comparatively convenient, simple simultaneously. The second channel 70 is fixed to the second beam 50 by two second clamps 71 and the first channel 60 is fixed to the first beam 30 by two first clamps 61, thereby enabling finally the interaction between the pipe system 40 and the main structure and the load transfer.

Specifically, the second channel steel 70 is connected with the first sleeve 21 through the first anti-seismic connector 72, so as to realize connection with the damping shock-absorbing diagonal bracing 20. The first channel 60 is connected to the vertical hanger 10 by a second shock resistant connection 62. The first shock resistant connection 72 is fixedly connected to the second channel 70 by a spacer with tooth and threaded connection. The second shock resistant connector 62 is fixedly connected to the first channel 60 by a spacer with tooth-shaped grooves and another threaded connector. The tooth-shaped groove tooth gasket has better biting action, and can certainly improve the stability of connection.

The second anti-seismic connector 62 may be fixed with a first nut 63, and in the case where the high-strength boom 11 described later is a high-strength full-thread boom, the first end of the high-strength full-thread boom may be engaged with the first nut 63, thereby realizing connection of the vertical hanger 10 and the second anti-seismic connector 62, and further realizing connection with the first channel steel 60.

The two ends of the high-strength boom 11 may be connected to the first beam 30 and the pipe system 40, respectively, specifically, by means of a fixed connection.

The high-strength suspender 11 passes through the groove of the groove-shaped steel 121, and a plurality of fasteners 122 can be fixedly connected with the groove-shaped steel 121 by tightening bolts, and the high-strength suspender 11 is clamped and fixed between the groove-shaped steel 121 and the fasteners 122. In this structure, the bolt can realize the detachable connection of the fastener 122 and the channel steel 121, so that a structure fixedly connected with the high-strength suspender 11 is formed between the fastener 122 and the channel steel 121, and the channel steel 121 can play a reinforcing role. The fastening member 122 may be a locking piece which is screwed to the channel steel 121, thereby easily forming a reinforcing structure fixedly coupled with the high-strength hanger bar 11 with the channel steel 121. To improve the uniformity of the fastening, the plurality of fasteners 122 may be uniformly distributed in the length direction of the channel steel 121.
