Description

Technical Field

[0001] This utility model relates to the field of prefabricated building connection nodes, specifically a modular prefabricated building connection node structure. Background Technology

[0002] Modular prefabricated buildings divide the entire building structure into several standardized modules. These modules are prefabricated in a factory and then assembled on-site using prefabrication methods to form a complete building structure. It is a type of prefabricated building where major components are prefabricated in a factory and assembled on-site. Building forms include modular concrete buildings, modular steel structure buildings, modular wood structure buildings, and various prefabricated combined structure buildings. To facilitate the connection of modular buildings and ensure connection stability, connection node structures are needed. The "A Node Connection Structure for Fully Prefabricated Modular Buildings" disclosed in application number "202320548747.5" is also an increasingly mature technology. Its "Embodiment of the present utility model: A Node Connection Structure for Fully Prefabricated Modular Buildings" Compared with existing technologies, the advantages of this connection structure are: it can ensure the smooth connection of modular buildings, effectively improve construction accuracy, reduce operational difficulty, and ensure structural stability. However, this connection node also has the following drawbacks during use: While the connection node, through the upper formwork node, lower formwork node, and bolts, can indeed facilitate the connection of modular prefabricated buildings, the connection strength provided by the above structure alone is not significant enough. Therefore, it is necessary to provide a connection node structure that can significantly enhance the connection strength of prefabricated buildings and improve assembly safety. In addition, the connection node structure is susceptible to concrete corrosion after long-term use, which may lead to connection node breakage. Therefore, it is necessary to provide a rust-proof and corrosion-resistant connection node structure that extends service life. Utility Model Content

[0003] This utility model provides a modular prefabricated building connection node structure, aiming to solve the problem that the connection strength of existing connection node structures needs to be improved.

[0004] To achieve the above objectives, this utility model provides a modular prefabricated building connection node structure, including upper beam-column and lower beam-column;

[0005] The connecting assembly includes an upper connecting plate embedded inside the upper beam column. A cross plate is fixedly connected to the upper end of the upper connecting plate. Several first fastening teeth are formed on the side surface of the cross plate. Side plates are fixedly connected to both sides of the upper connecting plate. Several second fastening teeth are formed on the side surface of the side plates. A lower connecting plate is embedded inside the lower beam column. Several positioning shafts are fixedly connected to the upper end of the lower connecting plate. Expansion sleeves are fitted on the side surfaces of the positioning shafts. An installation shaft is fixedly connected to the lower end of the lower connecting plate. Several reverse teeth are equidistantly connected in a circular array on the side surface of the installation shaft.

[0006] As a preferred embodiment of this utility model, the surface of the upper connecting plate is provided with several through holes, and two crossbars are fixedly connected to the inner walls of the two side plates.

[0007] As a preferred embodiment of this utility model, the lower end of the lower connecting plate is fixedly connected to a plurality of stabilizing shafts, and the side surfaces of the plurality of stabilizing shafts are equidistantly connected with a plurality of protrusions.

[0008] As a preferred embodiment of this utility model, a fastening bolt is fixedly installed on the upper end of the lower connecting plate.

[0009] In a preferred embodiment of this utility model, the upper connecting plate, the cross plate, and the lower connecting plate are all made of stainless steel.

[0010] In a preferred embodiment of this utility model, both the positioning shaft and the expansion sleeve are made of alloy steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When assembling the upper and lower beams and columns using connection nodes, firstly, the upper and lower connecting plates are cast into the upper and lower beams and columns respectively. At this time, the upper cross plate at the top of the upper connecting plate is embedded in the upper beam and column. The cross plate's side surface has several barbed first fastening teeth that fully fuse with the upper beam and column concrete, thus initially enhancing the connection strength between the upper connecting plate and the upper beam and column. Simultaneously, the second fastening teeth on both side plates further enhance the connection strength between the upper connecting plate and the upper beam and column. At the same time, several positioning shafts at the lower end of the lower connecting plate are embedded in the lower beam and column. At this point, the surface of the lower beam and column is installed... Several reverse teeth can significantly enhance the connection stability between the lower connecting plate and the lower beam and column. In addition, when the lower connecting plate and the upper connecting plate are connected, several positioning shafts are inserted into the upper connecting plate. As the positioning shafts go deeper, they expand the expansion sleeve. The expansion of the expansion sleeve can enhance the connection strength between the upper connecting plate, the lower connecting plate and the upper beam and column. Compared with the connection node in the existing technology "a fully prefabricated modular building node connection structure", this utility model can enhance the connection strength of the modular prefabricated building through the cooperation of the above structures, thereby enhancing the practicality of the connection node.

[0013] 2. When used in the connection node structure, the upper connecting plate, cross plate and lower connecting plate made of stainless steel can avoid corrosion when embedded in the concrete, thus initially extending the service life of the connection node structure. At the same time, the positioning shaft and expansion sleeve made of alloy steel can enhance the compressive and tensile strength. Compared with the connection node structure in the existing technology "a fully prefabricated modular building node connection structure", this utility model can easily avoid corrosion through the cooperation of the above structures, thus extending the service life of the connection node structure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see Figures 1-3 This utility model provides a modular prefabricated building connection node structure, including a connection component 100;

[0021] The connecting assembly 100 includes an upper connecting plate 101 embedded inside the upper beam column 201. A cross plate 102 is fixedly connected to the upper end of the upper connecting plate 101. Several first fastening teeth 103 are provided on the side surface of the cross plate 102. Side plates 104 are fixedly connected to both sides of the upper connecting plate 101. Several second fastening teeth 105 are provided on the side surface of the side plate 104. A lower connecting plate 106 is embedded inside the lower beam column 202. Several positioning shafts 107 are fixedly connected to the upper end of the lower connecting plate 106. An expansion sleeve 108 is sleeved on the side surface of the several positioning shafts 107. An installation shaft 109 is fixedly connected to the lower end of the lower connecting plate 106. Several reverse teeth 110 are connected in a ring array at equal intervals on the side surface of the installation shaft 109.

[0022] In one specific embodiment, the connecting component 100 not only significantly enhances the stability of the upper beam-column 201 and the lower beam-column 202 during assembly installation, thereby enhancing the practicality of the connection node structure, but also facilitates corrosion prevention through the cooperation of the above structures, thus extending the service life of the connection node structure. In use, the upper connecting plate 101 and the lower connecting plate 106 are first cast into the upper beam-column 201 and the lower beam-column 202 respectively. By embedding the upper cross plate 102 of the upper connecting plate 101 into the upper beam-column 201, the connection strength between the upper connecting plate 101 and the upper beam-column 201 is initially enhanced by the complete fusion of several barbed first fastening teeth 103 on the side surface of the cross plate 102 with the concrete of the upper beam-column 201. Simultaneously, several second fastening teeth 105 on the surfaces of the two side plates 104 further enhance the connection strength between the upper connecting plate 101 and the upper beam-column 201. Then, the lower... Several positioning shafts 107 at the upper end of the connecting plate 106 are embedded in the lower beam column 202. At this time, several reverse teeth 110 are installed on the surface of the lower beam column 202, which can significantly enhance the connection stability between the lower connecting plate 106 and the lower beam column 202. When the lower connecting plate 106 and the upper connecting plate 101 are connected, several positioning shafts 107 are inserted into the upper connecting plate 101. As the positioning shafts 107 go deeper, the positioning shafts 107 expand the expansion sleeve 108. The expansion of the expansion sleeve 108 can enhance the connection strength between the upper connecting plate 101, the lower connecting plate 106 and the upper beam column 201. In addition, the upper connecting plate 101, the cross plate 102 and the lower connecting plate 106 made of stainless steel can avoid rust and extend the service life. At the same time, the positioning shafts 107 and the expansion sleeve 108 made of alloy steel can significantly enhance the compressive and tensile strength of the connection node structure, so as to improve the practicality of the connection node structure.

[0023] Please see Figure 2 and Figure 3 The upper connecting plate 101 has several through holes 111 on its surface, and two crossbars 112 are fixedly connected to the inner walls of the two side plates 104.

[0024] In one specific embodiment, the through hole 111 facilitates the installation and positioning of the positioning shaft 107, improves the connection strength between the upper connecting plate 101 and the lower connecting plate 106, and the crossbar 112 embedded in the upper beam column 201 can further enhance the connection stability between the upper connecting plate 101 and the upper beam column 201.

[0025] Please see Figure 2 and Figure 3 The lower end of the lower connecting plate 106 is fixedly connected to several stabilizing shafts 121, and several protrusions 122 are equidistantly connected to the side surfaces of the several stabilizing shafts 121.

[0026] In one specific embodiment, the stabilizing shaft 121, together with several protrusions 122 on the side surface, can enhance the connection stability between the lower connecting plate 106 and the lower beam column 202, so as to improve the safety of use.

[0027] Please see Figure 2 and Figure 3 A fastening bolt 131 is fixedly installed on the upper end of the lower connecting plate 106.

[0028] In one specific embodiment, the fastening bolt 131 passes through the upper connecting plate 101 and connects with the upper beam column 201, thereby further enhancing the connection tightness between the upper connecting plate 101 and the lower connecting plate 106.

[0029] Please see Figure 2 and Figure 3 The upper connecting plate 101, the cross plate 102, and the lower connecting plate 106 are all made of stainless steel.

[0030] In one specific embodiment, the upper connecting plate 101, the cross plate 102, and the lower connecting plate 106, all made of stainless steel, can prevent rust, thereby extending the service life of the connection node structure.

[0031] Please see Figure 2 and Figure 3 Both the positioning shaft 107 and the expansion sleeve 108 are made of alloy steel.

[0032] In one specific embodiment, the positioning shaft 107 and expansion sleeve 108 made of alloy steel can enhance tensile and compressive strength, further extending the service life of the connection node structure.

[0033] Working principle: In use, the upper connecting plate 101 and the lower connecting plate 106 are first cast into the upper beam column 201 and the lower beam column 202, respectively. By embedding the upper cross plate 102 of the upper connecting plate 101 into the upper beam column 201, several barbed first fastening teeth 103 on the side surface of the cross plate 102 are completely fused with the concrete of the upper beam column 201, thereby initially enhancing the connection strength between the upper connecting plate 101 and the upper beam column 201. At the same time, several second fastening teeth 105 on the surface of the side plates 104 on both sides can further enhance the connection strength between the upper connecting plate 101 and the upper beam column 201. Then, several positioning shafts 107 on the upper end of the lower connecting plate 106 are embedded into the lower beam column 202, and several reverse teeth 11 are installed on the surface of the lower beam column 202. The 0 can significantly enhance the connection stability between the lower connecting plate 106 and the lower beam column 202. When the lower connecting plate 106 is connected to the upper connecting plate 101, several positioning shafts 107 are inserted into the upper connecting plate 101. At the same time, several positioning shafts 107 penetrate deeper, and the positioning shafts 107 expand the expansion sleeve 108. The expansion of the expansion sleeve 108 can enhance the connection strength between the upper connecting plate 101, the lower connecting plate 106 and the upper beam column 201. The upper connecting plate 101, the cross plate 102 and the lower connecting plate 106 made of stainless steel can avoid rust and extend their service life. At the same time, the positioning shafts 107 and the expansion sleeve 108 made of alloy steel can significantly enhance the compressive and tensile strength of the connection node structure, thereby improving the practicality of the connection node structure.
