Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a prefabricated wall connection structure, a wall assembly module, and a prefabricated bathroom. Background Technology

[0002] Prefabricated bathrooms include prefabricated modules such as main frame modules, ceiling modules, and wall assembly modules. Each prefabricated module is prefabricated in the factory and can be assembled after being transported to the construction site, which greatly shortens the construction time.

[0003] The wall assembly module includes a chassis module and multiple wall panels. During on-site construction, the wall panels need to be spliced ​​together first, and then hoisted onto the chassis module as a whole to connect the chassis module and the wall panels, forming an independent interior space. Existing detachable connection methods between the chassis module and wall panels generally involve inserting positioning posts and then fixing them with corner brackets. Specifically, positioning posts are installed at each corner of the top of the chassis module, and corresponding insertion holes are opened at each corner of the bottom of the wall panels. Multiple positioning posts are inserted one-to-one with multiple insertion holes. Corner brackets are installed at the corners where the chassis module connects to the wall panels (indoor or outdoor corners). The corner brackets are embedded into L-shaped slots corresponding to those in the chassis module and wall panels, and then fixed with bolts, ultimately completing the installation of the chassis module and multiple wall panels. See patents with authorization announcement numbers CN210396246U, CN218912378U, and CN111321803B for reference.

[0004] The installation and removal method of positioning post insertion and corner bracket fixing has the following problems: on the one hand, multiple insertion holes need to be precisely connected to multiple positioning posts, and the time to adjust the connection position of the wall panel during hoisting is relatively long; on the other hand, the corner bracket needs to be connected to the L-shaped slot or threaded hole at the corner of the wall panel, which takes a long time to install.

[0035] (III) Beneficial Effects

[0036] The beneficial effects of this utility model are:

[0037] By interleaving or staggering the first and second plug-in plates, the first plug-in plate can simultaneously abut against the front and rear end faces of the second plug-in plate, and the second plug-in plate can simultaneously abut against the front and rear end faces of the first plug-in plate, thereby achieving horizontal positioning of a pair of plug-in plates with high connection strength and alignment accuracy.

[0038] Compared to the hole-and-column interlocking method, the plate-type interlocking method has a larger clearance and is easier to insert. By arranging multiple prefabricated wall panel connection structures along the circumference of the wall panel, the interlocking plates on each side of the wall panel can work together to bear the force during vertical insertion. The second interlocking plate allows the wall panel to adapt to the installation position of the first interlocking plate for adjustment of the docking accuracy. During docking, only the first and second interlocking plates need to be roughly aligned, so the alignment adjustment of the wall panel assembly module is completed simultaneously during the insertion process of the prefabricated wall panel connection structure, which greatly reduces the installation time of the wall panel assembly module.

[0057] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0059] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0060] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; "connection" can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0061] See Figures 1 to 4 This utility model provides a prefabricated wall connection structure, including a first insertion plate 3 and a second insertion plate 4. The first insertion plate 3 includes a limiting plate 31 and wing plates 33 located on both sides of the limiting plate 31. The limiting plate 31 and the wing plates 33 are arranged in parallel and located on different planes to form a first insertion groove for the second insertion plate 4 to be inserted between the limiting plate 31 and the pair of wing plates 33. The second insertion plate 4 includes a T-shaped main plate 41 and sub-plates 43 located on both sides of the T-shaped main plate 41. The T-shaped main plate 41 and the sub-plates 43 are arranged in parallel and located on different planes to form a second insertion groove for the first insertion plate 3 to be inserted between the T-shaped main plate 41 and the pair of T-shaped main plates 41.

[0062] In this embodiment, during factory prefabrication, the first plug-in plate 3 is fixed to the side wall of the chassis module 1 by fasteners, and the second plug-in plate 4 is fixed to the side wall of the wall panel 2 by fasteners. During on-site construction, the wall panels 2 are first connected as a whole by tongue and groove joints, the whole is hoisted, and multiple first plug-in plates 3 and multiple second plug-in plates 4 are inserted and positioned one by one. Finally, the first plug-in plates 3 and second plug-in plates 4 are fixed by connectors. The prefabricated wall panel connection structure enables the rapid assembly and disassembly of the wall panel assembly module. Screws or bolts can be selected as fasteners and connectors.

[0063] The first plug-in plate 3 and the second plug-in plate 4 are both disposed on the outer wall of the wall assembly module. Multiple plug-in plates can be disposed on two parallel sides of the wall panel 2, or arranged circumferentially. This utility model constructs the prefabricated wall connection structure as a plate-type plug-in joint. By arranging the limiting plate 31 and the wing plate 33 parallel to each other and located on different planes, the gap between them forms the first plug-in groove. The second plug-in plate 4 is then inserted vertically into the first plug-in groove to complete the connection of the prefabricated wall connection structure. Similarly, by arranging the T-shaped main plate 41 and the secondary plate 43 parallel to each other and located on different planes, the gap between them forms the second plug-in groove. The first plug-in plate 3 is then inserted vertically into the second plug-in groove to further complete the connection of the prefabricated wall connection structure. By interleaving or staggering the first plug-in plate 3 and the second plug-in plate 4, the first plug-in plate 3 can simultaneously abut against the front and rear end faces of the second plug-in plate 4, and the second plug-in plate 4 can simultaneously abut against the front and rear end faces of the first plug-in plate 3, thereby achieving horizontal positioning of a pair of plug-in plates with high connection strength and alignment accuracy.

[0064] Compared to the hole-and-column interlocking method, the plate-type interlocking method has a larger clearance and is easier to insert. After arranging multiple prefabricated wall panel connection structures along the circumference of the wall panel 2, the interlocking plates on each side of the wall panel 2 can work together to bear the force during vertical insertion. The second interlocking plate 4 allows the wall panel 2 to adapt to the installation position of the first interlocking plate 3 to adjust the docking accuracy. During docking, it is only necessary to roughly align the first interlocking plate 3 and the second interlocking plate 4. This allows the alignment adjustment of the wall panel assembly module to be completed simultaneously during the insertion process of the prefabricated wall panel connection structure, which greatly reduces the installation time of the wall panel assembly module.

[0065] Furthermore, the first insertion plate 3 also includes a pair of first inclined plates 32 mirror-displayed on both sides of the limiting plate 31; one side of the first inclined plate 32 is connected to the limiting plate 31, and the other side is connected to the wing plate 33; a second insertion groove is formed between the end faces of the limiting plate 31 and the pair of first inclined plates 32 for the second insertion plate 4 to insert into. Specifically, the two sides of the first inclined plate 32 are correspondingly connected to the limiting plate 31 and the wing plate 33. Due to the certain inclination of the first inclined plate 32, a certain first gap is formed between the limiting plate 31 and the wing plate 33, and the second insertion plate 4 engages vertically with the first gap. Compared with the hole-and-post insertion method, the limiting margin of the first gap is larger, and the second insertion plate 4 is easier to engage into the first gap, improving the convenience of insertion. During the hoisting and lowering process, the first insertion plate 3 and the second insertion plate 4 self-adaptively engage, and then are fixed by connectors, which is convenient to operate and has a short docking time.

[0066] Secondly, the second connector plate 4 includes a pair of second inclined plates 42; the T-shaped main plate 41 includes a horizontal plate 411 and a vertical plate 412; the sub-plate 43 is disposed on one side of the vertical plate 412; one side of the second inclined plate 42 is connected to the vertical plate 412, and the other side is connected to the horizontal plate 411; the pair of second inclined plates 42 and the pair of sub-plates 43 are mirror images of each other on both sides of the vertical plate 412; a third connector slot is formed between the T-shaped main plate 41 and the pair of sub-plates 43 for the first connector plate 3 to be inserted; in the inserted state, the limiting plate 31 abuts against the front of the T-shaped main plate 41, and the wing plate 33 abuts against the back of the sub-plate 43. Similarly, the second inclined plate 42 has a certain inclination, so that a second gap is formed between the T-shaped main plate 41 and the sub-plate 43, and the first connector plate 3 is engaged with the second gap vertically. With the second connector plate 4 engaged between the first connector plate 3 and the wall panel 2, the second gap allows the first connector plate 3 to be engaged between the second connector plate 4 and the chassis module 1, improving the docking accuracy and the strength of the connection structure.

[0067] The first insertion plate 3 is vertically inserted into the third insertion slot, and the second insertion plate 4 simultaneously completes its vertical insertion into the first insertion slot, achieving staggered insertion of the first insertion plate 3 and the second insertion plate 4. The second insertion plate 4 can simultaneously abut against the front plate (front face) and back plate (rear face) of the first insertion plate 3, achieving horizontal positioning of the second insertion plate 4 and the first insertion plate 3. Furthermore, the staggered insertion connection method allows the wall panel 2 to adaptively swing to a vertical state via the second insertion plate 4, with alignment adjustment and insertion completed simultaneously, resulting in high insertion and positioning efficiency.

[0068] The first, second, and third insertion slots work together to complete the vertical insertion process simultaneously. Figure 1 The left and right position adjustment shown can adaptively adjust the docking position between the wall panel 2 and the chassis module 1 after coordinating with multiple prefabricated wall connection structures, thereby improving docking accuracy and construction efficiency.

[0069] Furthermore, when the fastener is a screw, the screw head is positioned inside the through hole of the wing plate 33 so that the wing plate 33 and the sub-plate 43 abut against each other. Specifically, by placing the screw head inside the through hole of the wing plate 33, the screw head will not touch the sub-plate 43. This ensures that the wing plate 33 and the sub-plate 43 abut against each other, thus ensuring the vertical accuracy of the wall panel 2. On the other hand, it avoids stress concentration at the contact point between the screw head and the sub-plate 43, extending the service life of the first insertion plate 3 and the second insertion plate 4.

[0070] Secondly, the second inclined plate 42 abuts against the top of the wing plate 33; the vertical plate 412 abuts against the pair of first inclined plates 32. Specifically, during insertion, if the second insertion plate 4 deviates laterally during vertical movement, for example towards... Figure 2 When the left side deflects, the first inclined plate 32 limits its movement, pushing the vertical plate 412 to the right until it is positioned on the central axis of the pair of first inclined plates 32, automatically achieving left-right alignment adjustment. Multiple interlocking plates on each side work together to ensure that the central axis of the entire assembly (multiple wall panels 2 after tongue-and-groove splicing) coincides with the central axis of the chassis module 1 before the second inclined plate 42 abuts against the top of the wing plate 33. When the second inclined plate 42 abuts against the top of the wing plate 33, if the overall top surface is tilted at a certain angle, the second inclined plate 42 can slide on the top of the wing plate 33 until it abuts at the corner where the top of the wing plate 33 meets the bottom of the second inclined plate 42, ensuring the overall top surface is parallel to the horizontal plane. This eliminates or reduces the distance between the chassis module 1 and the overall assembly, improving the reliability of the wall panel assembly module.

[0071] See you again Figure 3 The inner side of the sub-plate 43 abuts against the first inclined plate 32. Similarly, the position of the sub-plate 43 in the left and right directions is adjusted by the first inclined plate 32. By adjusting the position of the sub-plate 43 in the left and right directions by a pair of first inclined plates 32, the overall docking position accuracy on the chassis module 1 is further improved before the top of the second inclined plate 42 abuts against the wing plate 33. In the plugged state, the first plug-in plate 3 is located in the projection plane of the second plug-in plate 4 on the side wall of the wall assembly module. It can be regarded as the first plug-in plate 3 being embedded in the second plug-in plate 4, so that the first plug-in plate 3 basically does not occupy additional installation space, improving the adaptability of the prefabricated wall connection structure to different installation conditions.

[0072] In addition, see Figure 5This utility model also provides a wall assembly module, which includes the above-mentioned prefabricated wall connection structure; the wall assembly module also includes a chassis module 1, a wall panel 2, multiple connectors and multiple fasteners; the top end of the chassis module 1 abuts against the bottom end of the wall panel 2; the first plug-in plate 3 is installed on the outer wall of the chassis module 1 by multiple fasteners; the second plug-in plate 4 is installed on the outer wall of the wall panel 2 by multiple fasteners; after the first plug-in plate 3 and the second plug-in plate 4 are vertically inserted, they are fixed by multiple connectors.

[0073] The connector passes sequentially through the first plug-in plate 3 and the second plug-in plate 4 before connecting to the wall panel 2, achieving a stable connection between the chassis module 1 and the wall panel 2. The installation or separation of the first plug-in plate 3 and the second plug-in plate 4, and consequently the installation or separation of the chassis module 1 and the wall panel 2, can be achieved simply by disassembling and assembling the connector. This method is convenient and efficient. Compared to the method of inserting positioning posts and then fixing them with corner brackets, the wall assembly module integrates the connector on the plug-in plate, which not only improves the connection strength between the first plug-in plate 3 and the second plug-in plate 4, but also optimizes the interior space (no need to create slots) and the alignment adjustment time (corner bracket slot alignment).

[0074] In addition, the fasteners do not need to be disassembled when the wall assembly module is disassembled. The fasteners, the first plug-in plate 3 and the chassis module 1 are assembled as a whole, and the fasteners, the second plug-in plate 4 and the wall panel 2 are also assembled as a whole.

[0075] like Figure 6 As shown, the wall assembly module also includes functional components and connecting blocks 5; the wall panel 2 has a universal interface 11 connecting to its outer wall; one end of the connecting block 5 connects to the functional component, and the other end plugs into the universal interface 11. Specifically, the universal interface 11 connects to the interior space. The universal interface 11 can be a slot inside a solid wall panel 2; or it can be a block connected to the inside of a hollow wall panel 2, with a slot inside the block. Functional components can be selected as coat hooks 7, folding handrails 8, emergency buttons 9, or alarms 10. The functional components are plugged into the universal interface 11 via the connecting blocks 5. The connecting blocks 5 are compatible with the universal interface 11. Different functional components can be equipped with the same type of connecting blocks 5, allowing them to be installed individually on the wall panel 2, meeting the needs of quick assembly and disassembly of various functional components.

[0076] Optionally, the docking block 5 is an adapter block 6, which is detachably connected to the functional component. By detachably connecting the docking block 5 to the functional component, the functional component or the adapter block 6 can be replaced accordingly after the functional component is damaged or the adapter block 6 is worn, thus reducing maintenance costs.

[0077] See Figure 7The folding handrail 8 includes a handrail 81 and a base 82; one end of the handrail 81 is rotatably connected to the base 82, and the other end is connected to the adapter block 6 or the docking block 5; in the folded state, the free end of the handrail 81 rests against the wall surface of the wall panel 2. Specifically, by setting the connecting end of the folding handrail 8 as a hinge structure, the folding handrail 8 can rotate around the base 82 and be folded against the wall panel 2 for storage, thus optimizing the indoor space occupied by the folding handrail 8 when it is not in use.

[0078] Furthermore, this utility model also provides a prefabricated bathroom, the wall assembly module including the wall assembly module as described above; the wall assembly module also includes a main frame module and a ceiling module; the top of the wall assembly module is connected to the ceiling module; the wall assembly module is built into the main frame module. During installation, the wall assembly module is installed inside the beam of the main frame module. Because the first plug-in plate 3 occupies little space, the prefabricated wall connection structure, after connection, has an overall plate-like structure with a thinner thickness. Therefore, the small-volume and thin-thickness prefabricated wall connection structure is highly adaptable to installation on the main frame module, improving the reliability of the prefabricated wall connection structure externally placed on the wall assembly module.

[0079] It should be understood that the above description of the specific embodiments of this utility model is only for illustrating the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of this utility model should be covered by the protection scope of this utility model.
