Description

Technical Field

[0001] This utility model relates to the field of connection structure technology for prefabricated building components, specifically a quick connection node for prefabricated building components. Background Technology

[0002] Currently, in the construction of prefabricated buildings, steel plates are connected to two walls using L-shaped steel plate connectors secured with screws to fix the two walls in place. Figure 1 As shown, at the connection point of two mutually perpendicular walls on a horizontal plane, an L-shaped steel plate is used for connection. One end of the L-shaped steel plate is fixed to the end of wall A with screws, and the other end of the L-shaped steel plate is fixed to the end of wall B with screws. The ends of wall A and wall B are in contact and are perpendicular to each other on a horizontal plane.

[0003] After the above installation is completed, it is necessary to repair the contact point between the L-shaped steel plate connector and wall A or wall B, that is, the finishing layer of the L-shaped steel plate connector and wall A or wall B, in order to hide the L-shaped steel plate connector.

[0004] Therefore, to achieve the effect of concealing the connectors, it is inevitable to increase the number of exposed structural layers when installing building components, thereby increasing the amount of on-site finishing layer repair work. Utility Model Content

[0005] This utility model provides a connection node for prefabricated building components, which solves the problem that when using existing solutions for installation, exposed connectors will appear. To hide the connectors, the number of exposed structural layers during the installation of building components will inevitably increase, thereby increasing the amount of on-site surface repair work.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] A prefabricated building component connection node includes a wall A and a wall B arranged perpendicularly to each other. A blind hole nut is embedded in one end of the wall A. A sleeve is fitted on the wall B. A screw is fitted inside the sleeve. One end of the screw is screwed into the blind hole nut. A fixing mechanism is fitted on the screw inside the sleeve. The fixing mechanism is used to fix the screw inside the sleeve. The other end of the screw is located inside the sleeve. A decorative surface circular plate is installed at the other end of the sleeve.

[0008] It should be noted that holes are made at the contact surfaces of the structural columns at the ends of walls A and B, so that blind hole nuts can be welded to the holes, perpendicular to the contact surfaces and with the holes facing outwards.

[0009] As a preferred embodiment, the fixing mechanism includes a flat washer, a spring washer, and a nut. One end of the B wall has a through hole that communicates with the sleeve. The flat washer and the spring washer are sequentially sleeved on the screw located inside the sleeve, with one end of the flat washer contacting the inner sidewall of the through hole. The nut is also threaded onto the screw, with one end of the nut contacting one end of the spring washer and the other end of the spring washer contacting the other end of the flat washer.

[0010] It should be noted that a waist hole is opened at the contact surface between the structural column at the end of wall B and the structural column at the end of wall A, and an opening of the same diameter as the sleeve is opened on the parallel side. This ensures that when assembling the wall panel on site, it does not affect the screw passing through the waist hole to insert the blind hole nut and to perform the fastening assembly operation of the flat washer, spring washer, and nut.

[0011] As a preferred example, a sealing strip is also provided on the side wall of wall A, and the other end of the sealing strip corresponds to wall B. When wall A and wall B are fixed by screws, the sealing strip is squeezed by the two walls.

[0012] As a preferred example, wall A is provided with an end structural column, wall B is provided with an end structural column, and the sealing strip is disposed on the end structural column of wall A and between the end structural column of wall B.

[0013] As a preferred example, the sleeve is embedded in the structural column at the end of wall B and is perpendicular to the structural column at the end of wall B.

[0014] As a preferred example, a decorative surface plate is glued to the other end of the sleeve.

[0015] The beneficial effects of this utility model are as follows: Wall A and Wall B are connected by a screw with one end sleeved on a blind hole nut, while the other end is secured to a sleeve by a flat washer, a spring washer, and a nut to achieve fastening. After fastening, the other end of the screw is located inside the sleeve. A pre-made decorative surface layer circular plate is then glued to cover the hole in the sleeve, thereby covering the other end of the screw. This operation reduces or avoids the number of exposed structural layers required when installing building components, reduces the amount of on-site surface layer repair work, thus greatly shortening on-site assembly time, improving assembly efficiency, and reducing the impact of structural connections on the pre-installed decorative surface layer.

[0019] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] The connection nodes in this utility model are used for connecting wall panels with floor slabs and floor panels, and for connecting roof panels with wall panels and trusses.

[0021] The decorative finishes of walls A and B, excluding holes, are prefabricated in the factory.

[0022] After the structural frames of wall A and wall B, namely the end structural columns 8 of wall A and 9 of wall B, are manufactured, the decorative surface round panels are assembled in the factory, and six sleeves are reserved for fixing the decorative surface round panels. Then, the assembly is carried out in the following manner:

[0023] like Figure 2 As shown, a prefabricated building component connection node includes a wall A and a wall B arranged perpendicularly to each other. A blind hole nut 1 is embedded in one end of wall A. A sleeve 6 is fitted onto wall B, and a screw 2 is fitted inside the sleeve 6. One end of the screw 2 is screwed into the blind hole nut 1. A fixing mechanism (a flat washer 3, a spring washer 4, and a nut 5) is fitted onto the screw 2 inside the sleeve 6. One end of wall B has a through hole connected to the sleeve. The flat washer 3 and the spring washer 4 are sequentially fitted onto the screw 2 inside the sleeve 6, with one end of the flat washer 3 contacting the inner sidewall of the through hole. The nut 5 is also threaded onto the screw 2, with one end of the nut 5 contacting one end of the spring washer 4, and the other end of the spring washer 4 contacting the other end of the flat washer 3. The fixing mechanism is used to secure the screw 2. Rod 2 is fixed inside sleeve 6, and the other end of screw 2 is located inside sleeve 6. A decorative surface round plate is glued to the other end of sleeve 6. A wall A is provided with wall A end structure column 8, and wall B is provided with wall B end structure column 9 (sleeve 6 is embedded in wall B end structure column 9 and is perpendicular to wall B end structure column 9. In addition, the purpose of setting sleeve 6 is to prevent flat gasket 3, spring gasket 4, and nut 5 from falling into wall B end structure column 9 during the installation of wall B on the construction site). Sealing strip 7 is set on wall A end structure column 8 and wall B end structure column 9. When wall A end structure column 8 and wall B end structure column 9 are fixed by screw 2, sealing strip 7 is squeezed by the two walls to achieve the sealing and fastening function.

[0024] Wall A and Wall B are connected by a screw 2, one end of which is fitted onto a blind hole nut 1. The other end is secured to a sleeve 6 by a flat washer 3, a spring washer 4, and a nut 5. After securing, the other end of the screw 2 is located inside the sleeve 6. A pre-made decorative surface plate is then glued to cover the hole in the sleeve 6, thus covering the other end of the screw 2. This operation reduces or avoids the number of exposed structural layers required when installing building components, reduces the amount of on-site surface repair work, and thus greatly shortens on-site assembly time, improves assembly efficiency, and reduces the impact of structural connections on the pre-installed decorative surface.
