[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.
[0032] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 this application can be understood according to specific circumstances.
[0033] As mentioned in the background technology, in the tide of transformation of the construction field towards industrialization, prefabricated concrete buildings, with their high construction efficiency and environmental friendliness, are becoming a key force in promoting sustainable development and achieving the "dual carbon" goals. In particular, the beam-column nodes in prefabricated buildings are not only the cornerstone of structural integrity, but also directly related to the overall safety. Faced with the challenges of natural disasters, especially the frequent occurrence of earthquakes, it has become urgent to strengthen the seismic resistance and rapid post-earthquake recovery capabilities of these nodes. However, traditional connection methods often cannot take into account multi-functional requirements such as load-bearing, seismic resistance and easy repair, which hinders the development of prefabricated building technology.
[0034] In order to improve the above-mentioned problems, the present application proposes a replaceable assembled energy-absorbing node based on a lattice structure. The replaceable assembled energy-absorbing node based on the lattice structure is quick to connect and easy to implement during the construction process, which can reduce construction time and cost and improve construction efficiency. The lattice structure has high design flexibility and can be designed according to the needs of the structure. The nodes based on the lattice structure can show good energy absorption and shock absorption capabilities when natural disasters such as earthquakes occur. By directly replacing the assembled nodes with energy-absorbing devices, structural damage can be effectively concentrated on the energy-absorbing elements, thereby protecting concrete components and achieving the purpose of plastic controllable, easy replacement and reduced earthquake losses. The core energy-absorbing components in the energy-absorbing nodes can be replaced after earthquake damage or damage, thereby restoring the structure's use function and mechanical properties, and improving the structure's maintainability and service life.

[0039] It should be understood that the first II-shaped steel body 1 and the second II-shaped steel body 2 are installed in advance in the reinforced concrete column as embedded parts, and concrete is poured after the installation is completed.

[0044] A second connecting steel plate 7, wherein the second connecting steel plate 7 is arranged corresponding to the first connecting steel plate 6, one end of the second connecting steel plate 7 is fixedly and detachably connected to the end of the second II-shaped steel body 2 away from the reinforced concrete beam, and the second connecting steel plate 7 matches the corresponding surface of the second II-shaped steel body 2 in shape;
[0045] An upper steel plate 8 is arranged perpendicular to the first connecting steel plate 6, and both ends of the upper steel plate 8 are fixedly connected to the top of the first connecting steel plate 6 and the top of the second connecting steel plate 7 respectively;
[0046] A lower steel pad 9, wherein the lower steel pad 9 is arranged parallel to the upper steel pad 8, and both ends of the lower steel pad 9 are fixedly connected to the bottom of the first connecting steel plate 6 and the bottom of the second connecting steel plate 7 respectively;
[0047] The lattice cell 10 is arranged in the first connecting steel plate 6, the second connecting steel plate 7, the upper steel pad 8, and the lower steel pad 9, and the side walls of the lattice cell 10 are fixedly connected to the inner walls of the first connecting steel plate 6, the second connecting steel plate 7, the upper steel pad 8, and the lower steel pad 9 respectively.

By directly using the energy-absorbing device to replace the assembled node, the structural damage can be effectively concentrated on the energy-absorbing element, thereby protecting the concrete component. When the node is repaired after being damaged, only the lattice structure energy-absorbing component 3 is required to complete the node repair work; at the same time, after the energy-absorbing node is damaged, the high-strength long bolt 4 passes through the lattice structure energy-absorbing component 3, and is fixed at both ends of the high-strength long bolt 4 by nuts to prevent further damage to the lattice structure energy-absorbing component 3.
