Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and more specifically to a prefabricated bathroom installation structure. Background Art

[0002] Prefabricated decoration is a newly emerging form of decoration construction in recent years. As the name implies, it means that each component required for decoration is produced in the factory and then transported to the decoration site for combined installation, eliminating the operations such as measurement and cutting of each component at the traditional decoration site. The construction is simpler and more convenient, which can greatly improve the construction efficiency at the decoration site, and the construction site is cleaner and more beautiful, without generating too much decoration material waste. It is a more environmentally friendly form of decoration construction.

[0003] At present, prefabricated integral bathrooms all use an integrated bottom box as the base, and grooves or protrusions for clamping wall panels are provided at the edge of the bottom box, and then several wall panels are clamped on the bottom box to complete the overall installation of the prefabricated bathroom. For example, a waterproof bottom box structure for fixing wall panels disclosed in a Chinese patent with the application number CN202122216326.6, or as shown in a prefabricated bathroom installation structure disclosed in a Chinese patent with the application number CN202111238056.7.

[0004] It should be noted that in the prior art, when installing wall panels, only the clamping structure between the wall panels and the bottom box (for example, clamping the lower end of the wall panel in the bottom box) is used to position and support the wall panels, resulting in insufficient horizontal limit at the lap joint between the wall panels and the bottom box. Moreover, the wall panels are heavy and prone to the problem of wall panel tipping, and thus safety accidents are likely to occur, which is very dangerous. Summary of the Invention

[0005] The purpose of the present invention is to provide a prefabricated bathroom installation structure for the deficiencies of the prior art. By adding a vertical plug-in structure that is misaligned with the original connection structure, the clamping points between the wall panel and the bottom box are increased, the horizontal limiting effect of the bottom box on the wall panel is improved, and the possibility of the wall panel tipping is reduced.

[0006] The technical solution measures of the present invention are as follows:

[0007] A prefabricated bathroom installation structure, comprising:

[0008] A bottom box, the bottom box is provided with an upwardly open installation groove;

[0009] A wall panel, the bottom end of which is adaptively inserted into the installation groove;

[0010] The bottom box is provided with a clamping portion that is disposed on one side of the installation groove and protrudes upward;

[0011] A connecting piece is adaptively connected to one side of the wall panel, and the connecting piece is provided with an inserting groove which opens downwards and is adapted for the fitting of the clamping part.

[0012] In the above scheme, the bottom of the original wall panel is inserted into the installation groove of the bottom box, and on the basis of not changing the original structure of the wall panel, the connecting piece is additionally connected to the wall panel by means of, for example, screws, so that the wall panel and the connecting piece are formed into one body; at the same time, a clamping part which is inserted upward into the connecting piece is provided on the bottom box, and the clamping part is inserted upward into the connecting piece, so as to limit the plug-in position of the wall panel through the plug-in limit effect on the connecting piece, which is equivalent to limiting the wall panel through two staggered vertical plug-in structures, thereby enhancing the horizontal limiting effect of the bottom box on the wall panel and reducing the possibility of the wall panel tipping over.

[0013] As a further preferred solution, the connecting piece includes:

[0014] A fixing plate fixed to one side of the wall panel;

[0015] The transverse plate is arranged transversely and connected to the side of the fixing plate away from the wall plate, and the transverse plate is provided with a first plug-in plate and a second plug-in plate protruding downward, and the plug-in groove is formed between the first plug-in plate and the second plug-in plate.

[0016] As a further preferred solution, the transverse plate is further provided with a partition plate which is protruded downwards, and the partition plate is located at a distance on a side of the first plug-in board away from the second plug-in board;

[0017] A first connecting plate is connected between the first plug-in plate and the partition plate, and a second connecting plate is connected between the second plug-in plate and the fixing plate.

[0018] As a further preferred solution, the first connecting plate and / or the second connecting plate are connected to the upper end of the base box.

[0019] As a further preferred solution, the bottom box comprises:

[0020] substrate;

[0021] A top plate is disposed above the base plate at intervals;

[0022] A frame member, which covers the interval between the base plate and the top plate on one side, and is connected to one end of the base plate and one end of the top plate, so that the base plate, the top plate and the frame member together enclose a filling space, and the installation groove and the clamping portion are both provided on the frame member;

[0023] The foam glue is filled in the filling space to fix the base plate, the top plate and the frame member together.

[0024] Further as a preferred solution, the frame member includes:

[0025] A frame board, which is vertically arranged, and the upper end of the frame board forms the clamping portion;

[0026] A limiting board, which is spaced on one side of the frame board facing the filling space or on the side of the frame board facing away from the filling space, and is vertically arranged;

[0027] A storage board, which is horizontally arranged and is a connection structure between the frame board and the limiting board;

[0028] The frame board, the limiting board and the storage board jointly surround to form the installation groove.

[0029] Further as a preferred solution, the limiting board is placed on one side of the frame board facing the filling space, one end of the base plate is connected to the frame board, one end of the top plate is connected to the limiting board, and the storage board is located above the base plate.

[0031] And the bottom support plate is provided with a first reinforcing plate protruding upwards, and there is a space for accommodating the foaming glue between the upper end of the first reinforcing plate and the storage board.

[0032] Further as a preferred solution, the storage board is provided with a second reinforcing plate protruding downwards, and there is a space for accommodating the foaming glue between the lower end of the second reinforcing plate and the base plate.

[0033] Further as a preferred solution, a rib plate is provided at the angle between the frame board and the storage board. The rib plate is bent to form a vertical connecting portion vertically arranged and connected to the storage board, and a horizontal connecting portion horizontally arranged and connected to the frame board. The installation groove is formed between the vertical connecting portion and the limiting board.

[0034] The main beneficial effects of the above technical solutions are as follows:

[0035] By inserting the bottom end of the wall panel downward into the installation groove of the bottom box, and connecting a connecting piece on one side of the wall panel for the clamping portion of the bottom box to be inserted upward, the wall panel is limited by two vertically inserted structures arranged in a staggered manner, enhancing the horizontal limiting effect of the bottom box on the wall panel and reducing the possibility of the wall panel tipping over.

[0036] On the basis described above, for the bottom box with a multi-layer structure formed by stacking a substrate, foaming glue, and a top plate for the purpose of being lightweight, the structures of each layer are prone to shift when subjected to lateral forces, thereby resulting in a lower horizontal limiting ability for the wall panel. To address this problem, a border member that is simultaneously connected to the substrate, foaming glue, and top plate is specifically provided as the installation docking structure with the wall panel and the connecting member on the wall panel, which can better position and support the wall panel.

[0037] Further or more detailed beneficial effects will be described in combination with specific embodiments in the specific implementation manners. Brief Description of the Drawings

Specific Implementation Manners

[0048] The present invention will be specifically illustrated below in conjunction with embodiments:

[0049] Embodiment 1:

[0050] A bottom box, refer to Appendix Figure 1 to Appendix Figure 8 , which is used to be placed on the ground as the bottom structure for installing wall panel b to form a prefabricated bathroom.

[0051] As shown in Appendix Figure 2 , the bottom box a in this embodiment is a multi-layer structure formed by stacking a base plate a1, foaming glue a4, and a top plate a2 from bottom to top. Moreover, using waterproof foaming glue a4 as the bonding layer between the base plate a1 and the top plate a2 can not only reduce the weight of the bottom box but also has excellent waterproof effect.

[0052] At this time, a border needs to be set between the edge of the top plate a2 and the edge of the base plate a1 to prevent the foaming glue a4 from escaping between the top plate a2 and the base plate a1. However, the existing border is generally a strip-shaped plate and cannot perform clamping and positioning on the wall panel, resulting in the need to additionally set clamping members for the wall panel, increasing the complexity of the bottom box assembly.

[0053] Based on this, in this embodiment, the border structure is mainly improved and optimized.

[0054] Specifically, as shown in Appendix Figure 1 , the base plate a1 is placed at the bottom and used to be placed on the assembly ground, and the top plate a2 is spaced above the base plate a1. A border member a3 preferably made of metal profile is also provided. It laterally covers the spaced space between the base plate a1 and the top plate a2 on one side (such as the left side in Appendix Figure 1 ), and at the same time is connected to one end of the base plate a1 and one end of the top plate a2, so that the base plate a1, the top plate a2, and the border member a3 jointly enclose a filling space x, and the border member a3 is provided with an upward-opening installation groove a301 for clamping and positioning the wall panel b. The foaming glue a4 is filled in the filling space x to integrally fix the base plate a1, the top plate a2, and the border member a3 to form the bottom box a.

[0055] In this way, when installing the wall panel b, for example, as shown in Appendix Figure 4 , its bottom can be directly inserted into the installation groove a301, broadening the function of the border member a3, realizing the dual functions of a single part, and eliminating the need to additionally set clamping members for clamping and positioning the wall panel b on the bottom box a, reducing the complexity of the bottom box a assembly.

[0056] Among them, in actual use, the number of the border members a3 is determined according to the number of side edges of the bottom box that need to be inserted into the wall panel b. For example, the bottom box is generally a square structure with four side edges, so the base plate a1 and the top plate a2 are also adapted to be square structures. At this time, generally all four side edges need to be inserted into the wall panel b. Therefore, the number of the border members a3 is preferably four, and each border member a3 is respectively connected to one side.

[0057] Meanwhile, considering the high-humidity usage environment that is prone to occur in prefabricated bathrooms, it is easy to have water seepage in the bottom box, and there is a high demand for heat preservation; the foaming glue a4 is preferably a polyurethane foaming glue, which has good heat preservation performance, and the thermal conductivity is about 0.025, which is a good material for building heat preservation; it has good waterproof performance, the foam holes are closed, and the closing rate can reach 95%, and rainwater will not seep through the space; it has good bonding performance and can bond very firmly with materials such as wood, metal, masonry, and glass to ensure the stability of the overall structure of the bottom box.

[0058] Furthermore, the border member a3 in this embodiment is mainly composed of a border plate a302, a limiting plate a303, and a storage plate a304.

[0059] Specifically, as shown in the appendix Figure 3 The border plate a302 is arranged vertically; the limiting plates a303 are spaced on one side of the border plate a302 facing the filling space x or on the side of the border plate a302 facing away from the filling space x, and are arranged vertically; the storage plate a304 is arranged horizontally and is a connecting structure between the border plate a302 and the limiting plate a303; and the border plate a302, the limiting plate a303, and the storage plate a304 jointly surround to form an installation groove a301.

[0060] Among them, the limiting plate a303 can be spaced on the side of the border plate a302 facing away from the filling space x, that is, it is equivalent to that one side surface of the border plate a302 needs to be connected to the base plate a1, the top plate a2, and the foaming glue a4 at the same time. The limiting plate a303 and the storage plate a304 are both connected to the other side surface of the border plate a302 and are in a suspended state. It should be noted that at this time, when the wall panel b is inserted into the installation groove a301, it will exert a downward pressure on the storage plate a304 to drive the storage plate a304 to bend and drive the border member a3 to turn outwards, resulting in a risk that the border member a3 is easily separated from the base plate a1, the top plate a2, and the foaming glue a4.

[0061] Therefore, in order to reduce the above risks, in this embodiment, it is preferred that the limiting plate a303 is placed on the side of the border plate a302 facing the filling space x, one end of the base plate a1 is connected to the border plate a302, one end of the top plate a2 is connected to the limiting plate a303, and the storage plate a304 is located above the base plate a1, as shown in the appendix Figure 2 shown.

[0062] At this time, a part of the filling space x is also formed between the storage plate a304 and the base plate a1, and the foaming adhesive a4 will fill this part, making the storage plate a304 in a non-suspended state. In this way, when the wall panel b is inserted into the installation groove a301, this part of the foaming adhesive a4 and the base plate a1 at the bottom will provide upward support for the storage plate a304, reducing the possibility of the storage plate a304 being bent, and being able to provide a more stable bottom support for the inserted wall panel b.

[0063] To further improve the vertical support for the frame member a3, and thus ensure that the frame member a3 can provide a more stable limit support for the wall panel b. As shown in the appendix Figure 3 As shown, a bottom support plate a305 protruding towards the inside of the filling space x is provided on one side of the frame plate a302. The lower end surface of the bottom support plate a305 is connected to the upper end surface of the base plate a1, making the base plate a1 directly serve as the bottom support structure of the frame member a3, and at the same time increasing the connection area between the frame member a3 and the base plate a1, and between the frame member a3 and the foaming adhesive a4, so as to improve the stability of the fixed connection of the frame member a3.

[0064] Furthermore, considering that the frame member a3 as shown in the appendix Figure 2 is prone to lateral detachment when subjected to lateral forces. In this embodiment, as shown in the appendix Figure 3 As shown, a first reinforcing plate a3051 protruding upwards is provided on the bottom support plate a305, and a space for accommodating the foaming adhesive a4 is left between the upper end of the first reinforcing plate a3051 and the storage plate a304. On the one hand, it further increases the bonding area between the frame member a3 and the foaming adhesive a4, improving the stability of the bonding of the frame member a3; on the other hand, it makes a part of the frame member a3 vertically inserted into the foaming adhesive a4, enabling the foaming adhesive a4 to better limit the frame member a3 in the horizontal direction and preventing the frame member a3 from laterally detaching.

[0065] Similarly, as shown in the appendix Figure 3 As shown, a second reinforcing plate a3041 protruding downwards is provided on the storage plate a304, and a space for accommodating the foaming adhesive a4 is left between the lower end of the second reinforcing plate a3041 and the base plate a1.

[0066] Furthermore, as shown in the appendix Figure 3 As shown, a top support plate a306 protruding towards the inside of the filling space x is provided on one side of the limit plate a303. The upper end surface of the top support plate a306 is connected to the lower end surface of the top plate a2, making the top support plate a306 serve as the bottom limit support structure when installing the top plate a2, facilitating the installation of the top plate a2. At the same time, it can prevent the top plate a2 from moving down under its own gravity during the non-filling or filling of the foaming adhesive a4, resulting in the compression of the filling space x, so as to maintain the stability of the filling space x and avoid affecting the subsequent filling process of the foaming adhesive a4.

[0067] It should be noted that when the bottom box a is placed and the wall panel b is installed, generally, the wall panel b is pushed from the middle of the bottom box a towards the edge of the bottom box a until it reaches the installation groove a301. Then, the bottom of the wall panel b is inserted into the installation groove a301 and the wall panel b is pushed outwards to make the wall panel b in a vertical state. At this time, the wall panel b is prone to the risk of tipping outwards.

[0068] Based on this, as shown in the appended Figure 1 , appended Figure 2 , appended Figure 3 and appended Figure 4 In this embodiment, the upper end of the border plate a302 is higher than the top plate a2, and the upper end of the limiting plate a303 is lower than the top plate a2. In this way, according to the installation trajectory of the wall panel b, the limiting plate a303 lower than the top plate a2 will not hinder the movement of the wall panel b, enabling the wall panel b to smoothly move to the position of the installation groove a301 and insert its bottom into the installation groove a301; the border plate a302 higher than the top plate a2 forms a limiting structure to prevent the inserted wall panel b from tipping outwards, for example, to the left and tip over as shown in appended Figure 4 . Moreover, the higher the height of the border plate a302, the better the hindering effect.

[0069] Of course, the higher the height of the border plate a302, the more prone it is to be bent under force. Based on this, as shown in appended Figure 3 In this embodiment, a rib plate a307 is provided at the angle between the border plate a302 and the storage plate a304 to strengthen the anti-bending ability of the border plate a302 through the rib plate a307.

[0070] Specifically, as shown in appended Figure 3 , the rib plate a307 is bent to form a vertical connecting portion a3071 arranged vertically and connected to the storage plate a304, and a horizontal connecting portion a3072 arranged horizontally and connected to the border plate a302. An installation groove a301 is formed between the vertical connecting portion a3071 and the limiting plate a303.

[0071] Embodiment 2: Based on the bottom box a in Embodiment 1, an assembled bathroom installation structure is formed. The assembled bathroom installation structure includes the bottom box a and a plurality of wall panels b whose bottoms are inserted into the installation groove a301 of the bottom box a. The number of the wall panels b is set according to actual needs, and the wall panels b are fixed by means of splicing, snap connection or screw connection.

[0072] At this time, as shown directly in appended Figure 4 , the bottom of the wall panel b is inserted into the installation groove a301 of the bottom box a to form an assembled bathroom installation structure, but there is a problem that the horizontal limit of the bottom box a for the wall panel b is insufficient, resulting in the wall panel b being prone to tipping.

[0073] Based on this, as shown in the appendedFigure 5 As shown, in this embodiment, a clamping portion is provided on the bottom box a, which is placed on one side of the mounting groove a301 and protrudes upward. For this embodiment, the clamping portion is the upper end of the frame plate a302 in the first embodiment. Of course, for the bottom box a that is not provided with a frame member a3, the clamping portion can be any protruding structure provided on the bottom box a.

[0074] At the same time, a connector c, preferably a metal profile, is adaptively connected to one side of the wall panel b. The connector c is provided with an insertion groove c203 which opens downwards and is adapted for the clamping part to be inserted into.

[0075] In this way, as attached Figure 7 , Attachment Figure 8 As shown, when the wall panel b is installed, its bottom is inserted downward into the installation groove a301, and the upper end of the frame plate a302 in the bottom box a is inserted upward into the insertion groove c203 of the connecting member c fixed to the wall panel b; this is equivalent to limiting the wall panel b by two upper and lower plug-in structures arranged in an offset manner, thereby enhancing the horizontal limiting effect of the bottom box a on the wall panel b and reducing the possibility of the wall panel b tipping over.

[0076] It should be additionally explained that in this embodiment, the connecting member c is not inserted into the base box a, but the upper end of the frame plate a302 of the base box a is inserted upward into the connecting member c for setting. This is to enable the frame plate a302 or other similar structured clamping parts to serve as a support column structure equivalent to that inserted into the wall panel b, and the upper end of this support column can be close to the center of gravity of the wall panel b in the height direction, so as to better limit the horizontal position of the wall panel b and prevent it from tipping over.

[0077] Furthermore, as attached Figure 6 As shown, the connecting member c mainly includes a fixing plate c1 and a transverse plate c2.

[0078] Specifically, as attached Figure 5 and attached Figure 6 As shown, the fixing plate c1 is arranged vertically and fixed to one side of the wall panel b by screws; the horizontal plate c2 is arranged horizontally and connected to the side of the fixing plate c1 away from the wall panel b, and the horizontal plate c2 is provided with a first plug-in plate c201 and a second plug-in plate c202 protruding downward, and an insertion groove c203 is formed between the first plug-in plate c201 and the second plug-in plate c202.

[0079] As attached Figure 6As shown, a partition plate c204 is also convexly provided downward on the horizontal plate c2. The partition plate c204 is spaced on the side of the first plug-in plate c201 away from the second plug-in plate c202. A first connecting plate c205 is connected between the first plug-in plate c201 and the partition plate c204, and a second connecting plate c206 is connected between the second plug-in plate c202 and the fixing plate c1. To strengthen the structural strength of the first plug-in plate c201 and the second plug-in plate c202 and reduce the possibility of bending of the first plug-in plate c201 and the second plug-in plate c202.

[0080] Meanwhile, the first connecting plate c205 and / or the second connecting plate c206 are connected to the upper end of the bottom box a to serve as a vertical limiting structure when the wall panel b is installed, to prevent the lower end of the wall panel b from being over-inserted into the installation groove a301, and to increase the area where the bottom box a fits and supports the component structure formed by the wall panel b and the connector c, so as to improve the support stability of the wall panel b. For example, as shown in the attached Figure 8 figure, after the wall panel b is installed, the lower end face of the second connecting plate c206 is connected to the upper end face of the horizontal connecting part a3072.

[0081] The above are only the preferred embodiments of the present invention and do not limit the scope of the present invention. In addition, in the embodiments of the present invention, the terms "vertical", "horizontal", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product is usually placed during use.
