Description

Technical Field

[0001] The utility model belongs to the field of prefabricated houses, in particular to a connection node of assembled wall panels and a prefabricated house. Background Art

[0002] Prefabricated houses are residential or commercial buildings that are built using industrialized production methods. The main parts or all of the structural components of prefabricated houses (such as walls, floor slabs, roofs, etc.) are prefabricated in the factory production line and then transported to the construction site for assembly by professional transportation vehicles. Since most of the work is carried out in the factory, the on-site construction time is reduced and the construction efficiency is improved. Moreover, it can be carried out in any season and is not affected by climatic conditions. Prefabricated houses are easy to demolish, relocate or expand due to their modular design. In particular, for prefabricated houses without foundation structures, higher requirements are placed on the bearing capacity and performance of the wall panels.

[0003] Prefabricated wall panels are usually connected by embedded parts. Taking the Chinese utility model patent (publication number CN207063244U) as an example, the utility model discloses a connection node for non-load-bearing precast concrete exterior wall panels, which realizes the connection between the wall panel and the bottom plate / middle plate / top plate through precast dowels and / or a grouting structure attached to the precast dowels. However, for wall panels with large dead weight such as precast insulation wall panels, this type of connection node cannot provide reliable bearing capacity, and the installation method is relatively complicated, which affects the promotion and development of prefabricated wall panels. Therefore, there is an urgent need for a connection node for prefabricated wall panels with a simple structure and high bearing capacity. Utility Model Content

[0004] In order to overcome the above technical defects, the utility model provides a connection node of assembled wall panels and a prefabricated house to solve the problems involved in the background technology.

[0005] The utility model provides a connection node of assembled wall panels and a prefabricated house, comprising:

[0006] At least one first embedded part is fixedly mounted on one end of the wall panel, and a receiving groove with a concave cross-section is formed at the bottom of the first embedded part;

[0008] The second embedded part corresponds to the first embedded part one by one, the slot portion is embedded in the accommodating groove, and the first embedded part is fixedly mounted on the second embedded part through a hidden connecting part.

[0009] Preferably or optionally, the length of the slot portion is greater than the depth of the accommodating groove;

[0010] The slot portion and the inner wall of the accommodating groove are in transition or interference fit.

[0011] Preferably or optionally, one end of the connecting portion away from the supporting surface is bent outward to form an L-shaped or approximately L-shaped hook portion.

[0012] Preferably or optionally, the hidden connection member is a weld formed between the accommodating groove and the slot portion.

[0013] Preferably or optionally, the hidden connector includes: a countersunk hole provided on the receiving groove, a hole provided in the slot portion and corresponding to the countersunk hole, and a bolt penetrating through and installed between the countersunk hole and the hole.

[0014] Preferably or optionally, the support surface and the slot portion are an integrated structure.

[0015] The utility model also provides a prefabricated house, comprising: at least four wall panels, at least one bottom panel and at least one top panel;

[0016] The wall panel and the bottom panel are connected via the connection nodes of the assembled wall panel.

[0017] Preferably or optionally, the middle plate is a precast concrete plate; the wall plate is an RPC precast plate with built-in rock wool filling; and the top plate is an RPC precast plate with built-in rock wool filling.

DETAILED DESCRIPTION

[0024] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described. Example

[0025] See attached Figure 1 In this embodiment, a connection node of an assembled wall panel includes at least one first embedded part 100 and at least one second embedded part 200. That is, the first embedded part 100 has two forms: one is that a first embedded part 100 having the same length as the wall panel 300 is arranged at the bottom of the wall panel 300, and a second embedded part 200 having the same length as the wall panel 300 is arranged on the bottom plate 400; the other is that a plurality of first embedded parts 100 are evenly arranged at the bottom of the wall panel 300, and a plurality of second embedded parts 200 are evenly arranged on the bottom plate 400.

[0026] The first embedded part 100 is fixedly installed at one end of the wall panel 300, and a receiving groove 110 with a concave cross-section is formed at the bottom of the first embedded part 100; the second embedded part 200 includes a connecting part 210 embedded or inserted into the bottom plate 400 / middle plate / top plate 500, a supporting surface 220 fixedly installed on the connecting part 210, and a slot part 230 arranged on the supporting surface 220 and fitted with the inner wall of the receiving groove 110; the second embedded part 200 corresponds to the first embedded part 100 one by one, the length of the slot part 230 is greater than the depth of the receiving groove 110, and there is a transition or interference fit between the slot part 230 and the inner wall of the receiving groove 110, and the slot part 230 can be just embedded in the receiving groove 110, and the first embedded part 100 is fixedly installed on the second embedded part 200 through a hidden connecting part.

[0027] The connection node in this embodiment adopts mutually embedded slot parts 230 and accommodating grooves 110 to realize the positioning of the wall panel 300 and the bottom plate 400 / middle plate / top plate 500, and then the first embedded part 100 is fixedly installed on the second embedded part 200 through hidden connecting parts. The whole connection structure is simple and has high bearing capacity, which facilitates the promotion and application of prefabricated wall panels.

[0028] In a further embodiment, one end of the connection portion 210 away from the support surface 220 is bent outward to form an L-shaped or approximately L-shaped hook portion 211, thereby improving the connection strength between the second embedded component 200 and the bottom plate 400, thereby improving the bearing capacity of the connection node. The support surface 220 and the slot portion 230 are an integrated structure, which enhances the firmness and stability of the second embedded component 200 and improves the bearing capacity of the connection node.

[0029] In a further embodiment, the hidden connector includes: a countersunk hole provided on the receiving groove 110, a hole provided in the slot portion 230 and corresponding to the countersunk hole, and a bolt passing through and installed between the countersunk hole and the hole. The countersunk hole allows the head of the bolt to be hidden inside the countersunk hole, making the appearance of the connection node more concise and smooth. However, this connection method leads to a more complicated structure edge of the entire first embedded part 100 and the second embedded part 200, which increases the production cost and installation cost of the first embedded part 100 and the second embedded part 200. Therefore, as a preferred solution, the hidden connector is a weld formed between the receiving groove 110 and the slot portion 230. Among them, the first embedded part 100 and the second embedded part 200 are connected by welding, and the length of the slot portion 230 is greater than the depth of the receiving groove 110, reserving an operating space for welding the first embedded part 100 and the second embedded part 200. Example

[0030] See attached Figure 2 , this embodiment provides a prefabricated house, which can be a temporary house, a semi-permanent factory, or an equipment room. The prefabricated house includes: at least four wall panels 300, at least one bottom panel 400, and at least one top panel 500. For some prefabricated houses, at least one middle panel is also selected. The bottom panel 400 and the middle panel are both concrete prefabricated panels; the wall panel 300 is an RPC prefabricated panel 320 with rock wool filling 310, and the top panel 500 is an RPC prefabricated panel 320 with rock wool filling 310; the wall panel 300 and the top panel 500 are connected by screws 600, and the screws 600 are inserted through the top of the wall panel 300; the wall panel 300 and the bottom panel 400 and / or the middle panel and the wall panel 300 are connected by the connection nodes described in Example 1. Different connection nodes are designed according to the different structural characteristics of the middle plate and the top plate 500, so as to improve the aesthetics of the entire prefabricated house and reduce the cost of the entire prefabricated house while ensuring the structural strength of the entire prefabricated house.

[0031] In a further embodiment, a BRB energy-absorbing support member 700 is provided between the wall panel 300 and the top plate 500; the wall panel 300, the top plate 500 and the support member 700 form a triangular structure. The support member 700 is installed through a third embedded member 710, and the structure of the third embedded member 710 is similar to that of the second embedded member 200, which will not be described in detail here. Among them, the BRB energy-absorbing support member 700 can consume a large amount of energy through its unique hysteresis characteristics (i.e., the "S"-shaped curve generated during loading and unloading), thereby significantly reducing the vibration borne by the main structure and improving the seismic performance and safety of the prefabricated house.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
