Technical Field

[0001] The utility model belongs to the technical field of pipeline fixing, and in particular relates to a pipeline fixing bracket spanning a shock-absorbing and isolating area. Background Art

[0002] Building earthquake resistance has always been a difficult problem in the field of construction. Earthquake resistance technology has gone through rigid earthquake resistance (resisting vibration loads by strengthening the rigidity of the structure), flexible earthquake resistance (using flexible damping energy dissipation to reduce shock), and then a rigid-flexible earthquake resistance method was established (rigid constraints on the core tube of high-rise buildings to improve the stability of floors, and seismic isolation equipment is installed above the embedded parts of surrounding auxiliary buildings to reduce vibration loads).

[0003] After extensive research and improvements on the structure, the seismic technology for installing pipelines that coexist with the building structure and provide building functions appears to be relatively backward, with most using excessive treatments such as elbows and compensators.

[0023] The following is an explanation of the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied by other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and the features in the embodiments can be combined with each other without conflict. It should be noted that similar reference numerals and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further defined and explained in the subsequent figures.

[0024] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0025] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] refer to Figure 1 and Figure 2 As shown in the figure, a pipeline fixing bracket spanning a seismic isolation area is shown, and the pipeline 3 fixing bracket comprises: an outer protective sleeve 1, an energy dissipator 7, an energy dissipation conversion member 6 and a friction arc plate 4. In this embodiment, the outer protective sleeve 1 is a stainless steel structure.

[0027] The inner wall of the outer protective sleeve 1 is provided with a plurality of energy dissipators 7 , which are connected to the friction arc plates 4 via energy dissipation conversion components 6 , and the pipeline 3 to be fixed is clamped between the friction arc plates 4 .

[0028] Preferably, the energy dissipator 7 is a damping structure, so that the energy dissipation and vibration reduction of the pipeline 3 under the vibration load swing are completed through each damping structure.

[0029] Furthermore, a spring 8 is provided in the energy dissipator 7, and the spring 8 is fixedly connected to the energy dissipation conversion member 6. In this embodiment, the spring 8 is used to dissipate energy and reduce vibration of the pipeline 3 under the vibration load swing.

[0030] Preferably, the outer protective sleeve 1 is connected and fixed to the supporting structure through the outer wall ear plate 2. The fixed bracket of the utility model is used when crossing the shock-absorbing and isolating area. The bracket length is selected according to the friction resistance calculation, and the bracket setting spacing is selected according to the shock-absorbing and damping force.

[0031] Preferably, a plurality of energy dissipators 7 are arranged at equal angles in the outer protective sleeve 1. Further, three energy dissipators 7 are arranged at equal angles in the outer protective sleeve 1.

[0032] Preferably, the contact surface between the friction arc plate 4 and the pipeline 3 is a flexible contact surface. Alternatively, a flexible gasket is provided between the friction arc plate 4 and the pipeline 3. This ensures that there is sufficient friction between the friction arc plate 4 and the pipeline 3.

[0033] Preferably, each friction arc plate 4 is further provided with a limiting ring 5 on its outer side. The limiting ring 5 is provided to ensure that each friction arc plate 4 can effectively clamp and fix the pipeline 3.

[0034] When a vibration load is applied to the pipeline, the pipeline 3 transmits the vibration force to the friction arc plate 4, the friction arc plate 4 transmits the force to the energy dissipation conversion member 6, the energy dissipation conversion member 6 transmits the force to the spring 8, and finally the vibration load is unloaded through the elastic potential energy of the spring 8. When there is no vibration load on the pipeline 3, the pipeline 3 maintains balance against gravity through the friction resistance of the friction arc plate 4.

[0035] The utility model is simple to manufacture and can be used for both simple and easy purposes. It can keep balance under the friction resistance state at ordinary times and dissipate energy and reduce shock under the vibration load swing.

[0036] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
