Description

Technical Field

[0001] The utility model relates to the technical field related to building structure engineering, in particular to a replaceable, densely reinforced rib-type energy-absorbing beam segment structure. Background Art

[0002] The construction of nuclear power plants is an important part of the lifeline project in the development of nuclear power and plays a vital role in the country's economic and social development. When they are accidentally damaged by severe vibrations such as earthquakes, blasting, and impacts, due to their radioactive contamination, once leaked, they will pose a huge threat to the safety of people's lives and property. Therefore, the steel structure support performance in the main building of a nuclear power plant is of vital importance during construction.

[0003] In existing steel structure support frames, welding is usually used to connect the components together to form a whole to resist severe vibrations such as earthquakes. However, when the support is subjected to compression and tension, it will buckle, causing local deformation of the components. Once the components are damaged, the entire frame needs to be replaced, which prolongs the post-earthquake repair time. Utility Model Content

[0025] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0026] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0027] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0028] See also Figures 1 to 8 In an embodiment of the present invention, a replaceable encrypted stiffening rib type energy-absorbing beam segment structure includes a support frame structure, wherein the support frame structure includes a base plate 1 and a steel beam 2 arranged in parallel, and a first support frame 3 and a second support frame 4 are respectively arranged between the base plate 1 and the steel beam 2;

[0029] An energy-absorbing beam section 5 is provided between the second support frame 4 and the steel beam 2, and both ends of the energy-absorbing beam section 5 are detachably connected to the second support frame 4 and the steel beam 2 respectively;

[0030] The reinforcing rib structure is provided between the first supporting frame 3 and the second supporting frame 4 , and its two ends are detachably mounted to the first supporting frame 3 and the second supporting frame 4 respectively.

[0031] In detail, in this embodiment, the replaceable, densely reinforced, and stiffened rib-type energy-absorbing beam segment structure described in the present invention is adopted. The setting of the energy-absorbing beam segment 5 can effectively dissipate energy under the action of an earthquake and reduce damage to the main structural components. The key areas of the energy-absorbing beam segment 5 are subjected to concentrated force to ensure that the energy-absorbing beam segment 5 fully develops plastic deformation while the stiffening rib structure still does not buckle, so as to improve the overall stiffness and energy-absorbing capacity of the frame. The detachable connection method is adopted so that the energy-absorbing beam segment 5 damaged after the earthquake can be quickly replaced, which shortens the structural repair time to a certain extent.

[0032] Moreover, the stiffener structure plays the role of anti-buckling support, which is equivalent to the role of a "fuse", providing the first line of defense for the supporting frame structure. After the stiffener structure yields, the internal force of the structure is redistributed. At this time, the energy-absorbing beam section 5 becomes the second line of defense and still has earthquake resistance.

[0033] See also Figure 3 and Figure 4 The reinforcing rib structure includes a first reinforcing rod 6 and a second reinforcing rod 7. One end of the first reinforcing rod 6 is fixed to the second support frame 4 by a bolt, and the other end is slidably arranged in the second reinforcing rod 7. The end of the second reinforcing rod 7 away from the first reinforcing rod 6 is fixed to the first support frame 3 by a bolt.

[0034] Preferably, the first reinforcing rod 6 is provided with multiple groups of extrusion rings 601 along the axial direction.

[0035] Preferably, at least one set of limiting cavities is formed in the second reinforcing rod 7 , and the limiting cavities are composed of two annular limiting protrusions 701 .

[0036] As a further solution to this problem, please refer to Figure 5 An elastic structure is provided in the limiting cavity, and the elastic structure includes two abutment plates 8 that are slidably connected to the inner wall of the second reinforcing rod 7. A spring 9 is provided between the abutment plates 8. The spring 9 is sleeved on the first reinforcing rod 6, and the two ends of the spring 9 are respectively in abutment with the two abutment plates 8.

[0037] In general, whether the first reinforcing rod 6 and the second reinforcing rod 7 are compressed or stretched, the spring 9 is deformed by force. In the initial state, the spring 9 is in a natural state; when the first reinforcing rod 6 or the second reinforcing rod 7 is pulled or compressed, the extrusion ring 601 on the first reinforcing rod 6 interacts with the abutment plate 8, so that the spring 9 is compressed. When the external force is released, the spring 9 will push the first reinforcing rod 6 and the second reinforcing rod 7 to move in order to return to the initial state, thereby restoring the reinforcing rib structure to its original state.

[0038] The provision of the spring 9 significantly increases the supporting stiffness of the first reinforcing rod 6 and the second reinforcing rod 7, which can reduce the concentrated effect of component deformation, slow down the deformation speed of the supporting frame structure under strong earthquakes, and play a shock-absorbing role.

[0039] As a further solution to this problem, please refer to Figure 6 、 Figure 7 and Figure 8 The energy-absorbing beam section 5 includes an outer sleeve 12 , in which an inner core plate 11 of different shapes is arranged, and a filling material 10 is placed in the space between the inner core plate 11 and the outer sleeve 12 .

[0040] To expand on this, Figure 6 、 Figure 7 and Figure 8 As shown, the inner core plate 11 has different forms, such as cross shape, H shape, etc.; the outer sleeve 12 also has many styles, such as square, round, etc. The restraining effect of the outer sleeve 12 makes the inner core plate 11 not buckle when under pressure but achieve full cross-section yield, thereby making full use of the material properties. This is the essential difference between buckling restrained support and ordinary support.

[0041] The filling material 10 can be made of rubber or silicone. The function of the filling material 10 is to ensure the relative movement between the inner core plate 11 and the outer sleeve 12 .

[0042] It should be noted that the combined effect of the inner core plate 11, the outer casing 12 and the filling material 10 enables the buckling restrained support to not only improve the lateral stiffness of the structure, but also has good hysteretic energy dissipation capacity, and has a good energy dissipation and shock absorption effect under earthquake action.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
