Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a prefabricated repositionable assembly structure and its construction method. Background Technology

[0002] Prefabricated houses are houses built by prefabricating some or all of the building components in a factory, transporting them to the construction site, and assembling the components using reliable connection methods. Prefabricated houses include concrete prefabricated houses, wood structure prefabricated houses, and metal structure prefabricated houses.

[0003] Currently, the installation of prefabricated walls is mostly done by workers assembling them. The joints of prefabricated walls are prone to deformation when vibrated. Long-term deformation can affect the installation of the wall, and in severe cases, it may cause the wall to collapse, affecting personal safety. Summary of the Invention

[0004] This invention provides a prefabricated repositionable assembly structure and construction method to improve the safety and reliability of prefabricated walls after construction.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] A first aspect of the technical solution of the present invention provides an assembled resettable assembly structure, including a main board, a secondary board, and a protective shell connected between the main board and the secondary board. The protective shell is provided with a plug-in mechanism so that the main board and the secondary board can be plugged into each other.

[0007] The insertion mechanism includes:

[0010] The docking part has a first end connected to the secondary plate and a second end extending toward the main plate as a connecting post. The connecting post passes through the connecting hole and contacts the two reset posts.

[0011] When the main board and the secondary board are subjected to external force, the connecting post transmits the force to the two reset posts, causing the two reset posts to move away from each other; and when the external force disappears, the two reset posts move closer to each other under the action of elasticity, causing the connecting post to return to its original position.

[0012] Preferably, an observation window is provided on the protective shell in the area corresponding to the reset post, and a transparent observation plate is provided inside the observation window; furthermore, a first spring is provided between the transparent observation plate and the reset post to provide elastic return force.

[0014] When the connecting post is subjected to force and moves along the axial direction of the compression sleeve, the end face of the connecting post presses the V-shaped inclined surface, thereby causing the two reset posts to move away from each other; and when the connecting post is not subjected to force, the two first springs provide elastic return force, thereby causing the two reset posts to move closer to each other, thereby causing the connecting post to return to its original position.

[0015] Preferably, the connecting portion includes:

[0016] An outer tube, one end of which is provided with a connecting plate, which is connected to the motherboard;

[0017] An extrusion disc is disposed at the other end of the outer sleeve and contacts the extrusion sleeve to bear the pressure applied by the connecting column after the connecting column passes through the extrusion sleeve due to force.

[0018] A second spring is disposed inside the outer sleeve and located between the connecting disc and the extrusion disc to counteract the pressure applied by the connecting column.

[0019] Preferably, positioning protrusions are provided on both sides of the docking portion, and positioning grooves are provided on the outer wall of the protective shell in areas corresponding to the positioning protrusions. The positioning grooves engage or disengage with the positioning protrusions to limit the relative position of the docking portion and the protective shell or to release the position limitation.

[0020] Preferably, elastic limiting parts are installed on both sides of the positioning groove, the two elastic limiting parts correspond to each other and can move elastically in a preset direction so that when the positioning protrusion is engaged with the positioning groove, they respectively abut against the two sides of the positioning protrusion.

[0021] The preset direction is perpendicular to the insertion direction of the positioning protrusion and the positioning groove.

[0022] Preferably, the elastic limiting portion includes:

[0023] A limiting post is inserted into a limiting hole in the side wall of the positioning groove; wherein, limiting holes are respectively opened on the two side walls of the positioning groove along the preset direction;

[0024] A third spring is connected between the limiting post and the inner bottom wall of the limiting hole to provide elastic force;

[0025] The limiting post has an inclined surface at one end located in the positioning groove, and the inclined surfaces of the two limiting posts together form a V-shaped inclined surface. A V-shaped protrusion is formed on the end face of the positioning protrusion, and the V-shaped protrusion is aligned with the V-shaped inclined surface.

[0026] Preferably, a plurality of connecting posts are formed on the end face of the docking portion, and each connecting post corresponds to a reset portion and a connecting portion, so that the plurality of connecting posts are respectively connected to the plurality of reset portions.

[0027] Preferably, it further includes:

[0028] An insulation sleeve is fitted over the outside of the main board, secondary board, and protective shell for insulation purposes.

[0029] A second aspect of the present invention provides a construction method for a prefabricated, resettable assembly structure, applied to the aforementioned resettable assembly structure, comprising:

[0030] S1: Transport multiple motherboards and multiple secondary boards to the installation location and perform quality inspection on all motherboards and secondary boards; wherein, the motherboard is equipped with a protective shell and a connecting part and a reset part disposed within the protective shell, and the secondary board is equipped with a docking part;

[0031] S2: After the quality inspection is completed, place one of the sub-boards vertically on the ground;

[0032] S3: Lift the motherboard, align the mating part with the protective shell, and insert the connecting post into the connecting hole of the reset part to complete the assembly of a set of motherboard and secondary board;

[0033] S4: Use an insulation sleeve to wrap a set of main boards and secondary boards after assembly for use in wall assembly;

[0034] S5: Repeat steps S2-S4 above to assemble and wrap multiple sets of motherboards and secondary boards one by one to complete the entire construction process.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] (1) In this embodiment of the invention, the protective shell provides installation space for the plug-in mechanism and serves as an auxiliary connection between the main board and the secondary board. The plug-in mechanism, as the core of the entire structure, plays the role of connection and reset. The plug-in mechanism includes a connecting part, a reset part, and a mating part. When the main board and the secondary board are subjected to external forces (e.g., vibration), the connecting post on the mating part transmits the force to the two reset posts of the reset part, causing the two reset posts to move away from each other. Furthermore, when the external force disappears, the two reset posts move closer to each other under the action of elasticity, thereby causing the connecting post to return to its original position, thus realizing the reset function.

[0037] (2) By opening an observation window in the area corresponding to the reset column on the protective shell and installing a transparent observation plate in the observation window, the compression of the first spring can be observed in real time, thereby judging the usage status of the extrusion plate, eliminating potential hazards in time, and ensuring the safety of the wall.

[0038] (3) The positioning groove and the positioning protrusion cooperate to position the main board and the secondary board, thereby improving the convenience of assembly. Furthermore, by providing an elastic limiting part in the positioning groove, the positioning protrusion can be abutted and limited to improve the reliability of the connection.

[0039] (4) Both reset posts have inclined surfaces, which together form a V-shaped inclined surface and cooperate with the connecting post to facilitate the transmission of force. In addition, the two elastic limiting parts in the positioning groove also form a V-shaped inclined surface and cooperate with the V-shaped protrusion on the end face of the positioning protrusion to improve the convenience of the positioning groove and the positioning protrusion insertion.

Detailed Implementation

[0052] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0053] like Figure 1 As shown in the figure, an assembly-type resettable combination structure provided by an embodiment of the present invention includes a main board 1, a secondary board 2, and a protective shell 3 connecting the main board and the secondary board. The protective shell is provided with a plug-in mechanism 4 so that the main board 1 and the secondary board 2 can be plugged into each other to complete the assembly. Wherein, after the main board 1 and the secondary board 2 are assembled, if the main board 1 and the secondary board 2 are slightly misaligned due to external forces, the plug-in mechanism 4 can realize an automatic reset function (described in detail below) to ensure the stability of the structure in use.

[0054] Specifically, in this embodiment, both the main board 1 and the secondary board 2 are prefabricated components, forming a rectangular slab structure that serves as the wall of the prefabricated building. In other embodiments, the specific shapes of the main board 1 and the secondary board 2 can be adjusted according to different engineering requirements to meet different usage needs, such as being adjusted to cylindrical, square, or other support structures.

[0055] In this embodiment, the protective shell 3 is an annular hollow shell, used to provide installation space for the insertion mechanism 4 and to assist in connecting the main board 1 and the secondary board 2. Specifically, as shown... Figure 1 As shown, the protective shell 3 is a rectangular hollow shell, with its upper end plugged into the main board 1 and its lower end plugged into the secondary board 2.

[0056] In this embodiment, the plug-in mechanism 4 is the core of the entire structure, serving the functions of connection and resetting. (Refer to...) Figures 2 to 5 As shown, the insertion mechanism 4 includes a connecting part 41, a resetting part 42, and a mating part 43. The first end of the connecting part 41 (i.e., Figure 3 The right end of the connector 41 is connected to the motherboard 1 to ensure the stability of the plug-in mechanism 4. The reset part 42 is located at the second end of the connector 41 (i.e., the right end of the connector 41). Figure 3 The left end of the mating part 43 is used to provide a reset function. The first end of the mating part 43 (i.e., the left end) Figure 4 The right end of the mating part 43 is connected to the secondary plate 2. The second end of the mating part 43 extends toward the main plate 1 to form a connecting post 431. The connecting post 431 is used to cooperate with the reset part 42 to achieve connection and reset together.

[0057] The structural composition of the plug-in mechanism 4 is described in detail below:

[0058] like Figure 3 As shown, in this embodiment, the connecting part 41 includes an outer tube 411, a pressing plate 412, a second spring 413, and a connecting plate 414. The outer tube 411 is cylindrical, and the connecting plate 414 is located at the right end of the outer tube 411 for connection to the main board 1. The pressing plate 412 is located at the left end of the outer tube 411 and contacts the pressing sleeve 421 of the reset part 42 to withstand pressure from the connecting post 431. The second spring 413 is located inside the outer tube 411 and between the connecting plate 414 and the pressing plate 412 to counteract the pressure applied by the connecting post 431.

[0059] It should be understood that in this embodiment, the connecting part 41 mainly serves to connect the main board 1. Under normal circumstances, the extrusion plate 412 does not directly contact the connecting post 431. However, when the main board 1 and the secondary board 2 are subjected to a large external force (e.g., vibration), the connecting post 431 will pass through the extrusion sleeve 421 of the reset part 42, thereby applying a force to the extrusion plate 412. At this time, the extrusion plate 412 bears the pressure applied by the connecting post 431, and is buffered by the second spring 413 to gradually offset the pressure.

[0060] like Figure 3As shown, the reset part 42 includes a compression sleeve 421 and two reset posts 422. The compression sleeve 421 is cylindrical in shape, and has a connecting hole 4211 along its axial direction and a reset hole 4212 along its radial direction, the reset holes 4212 communicating with the connecting hole 4211. Correspondingly, the two reset posts 422 are reciprocally movable within the reset holes 4212, moving closer to or further away from each other. Furthermore, one end of each reset post 422 located inside the compression sleeve has a bevel, and the bevels of the two reset posts correspond to each other, forming a V-shaped bevel. The connecting hole 4211 is used to connect with the connecting post 431, so that the connecting post 431 passes through the connecting hole 4211 and contacts the V-shaped bevel formed by the two reset posts 422.

[0061] Therefore, when the main board 1 and the secondary board 2 are subjected to external forces (e.g., vibration), the connecting post 431 transmits the force to the two reset posts 422, causing the two reset posts 422 to move away from each other. Furthermore, when the external force disappears, the two reset posts 422 move closer together under the action of elasticity, causing the connecting post 431 to return to its original position, thus achieving the reset function.

[0062] Reference Figure 1 and Figure 6 As shown, in this embodiment, an observation window 31 is provided on the protective shell 3 in the area corresponding to the reset post 422, and a transparent observation plate 423 is provided inside the observation window 31; furthermore, a first spring 424 is provided between the transparent observation plate 423 and the reset post 422 to provide elastic return force. Thus, when the connecting post 431 moves and squeezes the inclined surfaces of the two reset posts 422, the reset posts 422 will squeeze the first spring 424. The compression status of the first spring 424 can be observed through the transparent observation plate 423. If the first spring 424 remains in a compressed state for a long time without being subjected to other external forces, it indicates that the compression plate 412 has been damaged due to prolonged use and needs to be replaced to ensure the use of the wall.

[0063] like Figure 5 As shown, in this embodiment, the docking part 43 is a plate-shaped structure connected to the secondary plate 2, and positioning protrusions 432 are provided on both sides of the docking part 43. Correspondingly, positioning grooves 32 are provided on the protective shell 3 in the area corresponding to the positioning protrusions 432. The positioning grooves 32 and the positioning protrusions 432 engage or disengage to limit the relative position of the docking part 43 and the protective shell 3 or to release the position limitation. It can be understood that the mutual cooperation of the positioning grooves 32 and the positioning protrusions 432 can enable the main plate 1 and the secondary plate 2 to be installed and positioned, thereby improving the convenience of assembly.

[0064] like Figure 3 and Figure 7As shown, in this embodiment, preferably, elastic limiting portions 33 are installed on both side walls of the positioning groove 32, the two elastic limiting portions 33 correspond to each other, and can move along a preset direction (i.e.: Figure 7 The positioning protrusion 432 can move elastically in the left and right directions. When the positioning protrusion 432 is engaged with the positioning groove 32, it abuts against the two sides of the positioning protrusion 432 respectively, thereby limiting the positioning protrusion 432 to prevent it from dislodging from the positioning groove 32 and improving the stability of the installation.

[0065] Specifically, in this embodiment, the elastic limiting part 33 includes a limiting post 331 and a third spring 332. Limiting holes 321 are respectively formed on the two side walls of the positioning groove 32 in the left-right direction. The two limiting posts 331 are respectively inserted into the limiting holes 321 on the two side walls of the positioning groove 32. The third spring 332 is connected between the limiting post 331 and the inner bottom wall of the limiting hole 321 to provide elastic force.

[0066] Preferably, the end of the limiting post 331 located within the positioning groove 32 has an inclined surface, and the inclined surfaces of the two limiting posts together form a V-shaped inclined surface. A V-shaped protrusion 4321 is formed on the end face of the positioning protrusion 432, and the V-shaped protrusion is aligned with the V-shaped inclined surface. Thus, through the mutual cooperation of the V-shaped protrusion and the V-shaped inclined surface, it is easy for the positioning protrusion 432 to be inserted into the positioning groove 32, and the positioning protrusion 432 is abutted and limited.

[0067] In addition, refer to Figure 3 and Figure 5 As shown, in this embodiment, preferably, a plurality of connecting posts 431 are formed on the end face of the docking part 43, and each connecting post 431 corresponds to a reset part 42 and a connecting part 41, so that the plurality of connecting posts 431 are respectively connected to the plurality of reset parts 42, thereby improving the reliability of the connection.

[0068] like Figure 8 As shown, in this embodiment, the resettable assembly structure also includes a heat insulation sleeve 5. After the main board 1 and the secondary board 2 are assembled through the protective shell 3 and the plug-in mechanism 4, the heat insulation sleeve 5 is fitted onto the outside of the main board 1, the secondary board 2, and the protective shell 3 for heat insulation.

[0069] The construction process of a prefabricated resettable modular structure provided by an embodiment of the present invention is described in detail below:

[0070] S1: Transport multiple motherboards 1 and multiple secondary boards 2 to the installation location, and perform quality inspection on all motherboards 1 and secondary boards 2. Among them, the motherboards 1 are equipped with a protective shell 3 and a connecting part 41 and a reset part 42 disposed within the protective shell, and the secondary boards 2 are equipped with a docking part 43.

[0071] S2: After the quality inspection is completed, place a secondary board 2 vertically on the ground.

[0072] S3: Lift the main board 1, align the positioning protrusion 432 on the mating part 43 with the positioning groove 32 on the protective shell 3, until the connecting post 431 is inserted into the connecting hole 4211 of the reset part 42, and complete the assembly of a set of main board 1 and secondary board 2.

[0073] S4: Use an insulation sleeve 5 to wrap a set of main board 1 and secondary board 2 after assembly for use in assembling the wall.

[0074] S5: Repeat steps S2-S4 above to assemble and wrap multiple sets of motherboard 1 and secondary board 2 one by one to complete the entire construction process.
