It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0018] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0019] This embodiment discloses a prefabricated building connection node structure and a prefabricated building. The connection node structure 10 of this embodiment can fix two structures 20 to be connected that need to be assembled vertically together, and can be applied to corner positions in prefabricated buildings. First, the connection node structure 10 of this embodiment will be described.

[0020] like Figure 1 and Figure 2 As shown, the connection node structure 10 of this embodiment includes two pre-embedded mechanisms 100 and an L-shaped connector 200. The two pre-embedded mechanisms 100 are respectively disposed on the first structure to be connected 21 and the second structure to be connected 22. The two side walls of the L-shaped connector 200 are respectively attached to the two pre-embedded mechanisms 100 and connected to the pre-embedded mechanisms 100.

[0021] like Figure 3 and Figure 4As shown, the pre-embedding mechanism 100 includes a pre-embedded steel strip 110 and a pre-tightening assembly 120. The pre-embedded steel strip 110 is pre-embedded and fixed on the to-be-connected structure 20 (i.e., the first to-be-connected structure 21 or the second to-be-connected structure 22). Since the pre-embedding mechanism 100 in the embodiment corresponds to the to-be-connected structure 20 one by one, it can be understood that the pre-embedded steel strip 110 of one pre-embedding mechanism 100 is arranged on the first to-be-connected structure 21, and the pre-embedded steel strip 110 of another pre-embedding mechanism 100 is arranged on the second to-be-connected structure 22. The pre-embedded steel strips 110 of the two pre-embedding mechanisms 100 are both provided with a first sliding groove 110a along the length direction thereof, and the length directions of the pre-embedded steel strips 110 of the two pre-embedding mechanisms 100 are perpendicular to each other. Specifically, the length directions of the two pre-embedded steel strips 110 are perpendicular to each other in a vertical plane, and the vertical plane is parallel to the side surface of the first to-be-connected structure 21. In this way, the pre-tightening assemblies 120 of the two pre-embedding mechanisms 100 can be adjusted in the height direction and the horizontal direction to connect the positions, and the flexible assembly of the two to-be-connected structures 20 can be realized.

[0022] As shown in Figure 3 and Figure 4 The pre-tightening assembly 120 is arranged one by one with the pre-embedded steel strip 110. The pre-tightening assembly 120 can slide in the first sliding groove 110a of the pre-embedded steel strip 110, specifically along the length direction of the first sliding groove 110a (i.e., the length direction of the pre-embedded steel strip 110), so that the pre-tightening assembly 120 can change the connection position with the L-shaped connecting piece 200, and the L-shaped connecting piece 200 and the pre-embedded steel strip 110 are fixedly connected together through the pre-tightening assembly 120. The pre-tightening assembly 120 includes a sliding bolt 121, a backing plate 122 and a nut 123. The head of the sliding bolt 121 is arranged in the pre-embedded steel strip 110. The sliding bolt 121 can slide along the length direction of the first sliding groove 110a to change the connection position. The outer diameter of the head of the sliding bolt 121 is larger than the width of the first sliding groove 110a, so that the sliding bolt 121 can be prevented from being separated from the first sliding groove 110a. The sliding bolt 121 is arranged in the L-shaped connecting piece 200 along the axial direction thereof. The backing plate 122 and the nut 123 are sequentially sleeved on the sliding bolt 121. The backing plate 122 is attached to the side surface of the L-shaped connecting piece 200. The nut 123 threadedly connected with the sliding bolt 121 can press the backing plate 122 on the L-shaped connecting piece 200. The L-shaped connecting piece 200 and the pre-embedded steel strip 110 are clamped together by the head of the sliding bolt 121 and the nut 123 to realize the connection and fixation therebetween.

[0023] As shown in Figure 4As shown in the drawings, in some preferred embodiments, the pre-embedded mechanism 100 further comprises a dowel 130, one end of the dowel 130 is connected with the pre-embedded steel strip 110, and the dowel 130 is located on the side of the pre-embedded steel strip 110 away from the L-shaped connecting piece 200. In this embodiment, the dowel 130 is fixedly connected with the pre-embedded steel strip 110 perpendicularly, and at least part of the dowel 130 is arranged in the first to-be-connected structure 21 or the second to-be-connected structure 22. When the pre-embedded steel strip 110 is pre-embedded into the to-be-connected structure 20, the dowel 130 is also pre-embedded into the to-be-connected structure 20. In this embodiment, the purpose of arranging the dowel 130 is to enable the pre-embedded steel strip 110 to be firmly fixed in the to-be-connected structure 20, so as to ensure the stability of the node position.

[0024] In some preferred embodiments, the pre-embedded steel strip 110 and the dowel 130 are integrally formed, which can significantly improve the strength of the structure. In some other embodiments, the pre-embedded steel strip 110 and the dowel 130 can be welded.

Among them, the back sides of the dowel head 131 and the pre-embedded steel strip 110 are respectively located on the two sides of the to-be-connected structure 20, which functions to position the pre-embedded steel strip 110 on the to-be-connected structure 20. In some other embodiments, the number of dowels 130 can be arranged one-to-one corresponding to the number of pre-embedded steel strips 110, or the number of dowels 130 can be more than the number of pre-embedded steel strips 110. A plurality of dowels 130 are arranged on the back side of the pre-embedded steel strip 110, which can further increase the stability between the pre-embedded steel strip 110 and the to-be-connected structure 20.

[0026] As shown in the drawings, Figure 3As shown, the shape of the L-shaped connecting piece 200 is configured as a plate-shaped L shape, specifically, the L-shaped connecting piece 200 includes a first flat plate part 210 and a second flat plate part 220, the first flat plate part 210 and the second flat plate part 220 are connected vertically to form an L-shaped structure, the first flat plate part 210 is attached to the side of one embedded steel bar 110, the second flat plate part 220 is attached to the side of another embedded steel bar 110, and the right angle part formed by the connection of the first flat plate part 210 and the second flat plate part 220 is just adapted to the right angle formed by the attachment of the first to-be-connected structure 21 and the second to-be-connected structure 22.
