A method and structure for connecting assembled bathroom floor and room body

Abstract

A method for connecting an assembled bathroom floor to a bathroom structure includes providing a mounting frame to securely connect the bathroom structure to the outer edges of the mounting frame; placing the floor over the upper surface of the mounting frame, and then securing the floor's underside to the upper surface of the mounting frame. The mounting frame forms a relatively fixed structural connection between the floor and the bathroom structure, eliminating any fixed connection points on the upper surface of the floor. This effectively maintains the floor's seal and facilitates installation and removal. Adjustments are directly operated from an access panel outside the bathroom structure to secure the floor to the upper surface of the mounting frame, making it easy for installers to secure the floor even when space inside the bathroom is limited.

Description

Technical Field

[0001] The present invention relates to the field of bathrooms, and in particular to a method and structure for connecting an assembled bathroom floor and a room body. Background Art

[0002] Prefabricated toilets are easy to disassemble and move, have high space utilization, and occupy a small area. They are widely used in railway locomotives, aircraft, and outdoor integrated toilets. However, in railway locomotive applications, due to the limited space inside the locomotive carriage, existing prefabricated toilets are assembled by connecting the various components with bolts. This assembly method is time-consuming and very inconvenient. Moreover, after installation, inspection and maintenance are required, which is also very inconvenient. In particular, the floor structure of the interior of the toilet of railway locomotives in my country is complex. The floor must be fastened to the toilet bowl, floor drain, and interior wall with screws. This makes assembly and disassembly difficult and time-consuming, and maintenance is inconvenient, labor-intensive, and costly. It is also unsightly and can cause leakage and unusability due to improper assembly. Therefore, how to quickly and easily disassemble and repair prefabricated toilets in a limited space is closely related to the layout of the various components and the connection structure between them. By rationally designing the layout of the components and improving the connection structure, the internal space of the prefabricated toilet can be fully utilized and the efficiency of disassembly and maintenance can be improved. Furthermore, during use, prefabricated restrooms can experience leakage from the floor and interior of the restroom. Severe leakage can short-circuit related equipment below the prefabricated restroom, impacting the normal operation of the entire locomotive. In existing technology, the floor and the restroom are secured together using multiple bolts, making disassembly and maintenance very cumbersome. Furthermore, due to the presence of leaks between the bolts, the restroom, and the floor, leakage can be severe. Therefore, within the field, it is of great significance to develop a method and structure for connecting the prefabricated restroom floor and restroom that utilizes space efficiently, facilitates assembly and disassembly, and provides an integrated connection. Summary of the Invention

[0003] The purpose of the present invention is to address the shortcomings of the existing rail locomotives, such as the limited space inside, and the difficulty of conveniently and quickly disassembling and assembling conventional assembled toilets for inspection and maintenance. The present invention proposes a method and structure for connecting the floor of an assembled toilet to the body of the toilet that can adapt to the limited space inside a rail locomotive. The method and structure for connecting the floor of an assembled toilet to the body of the toilet can be quickly and conveniently disassembled and assembled in the limited space inside a rail locomotive.

[0004] To achieve the purpose of the present invention, the technical solution adopted by the present invention is as follows: a method for connecting an assembled bathroom floor to a room body is proposed, providing a mounting frame to fixedly connect the room body to the outer edge of the mounting frame; after the floor is covered on the upper surface of the mounting frame, the bottom surface of the floor is fixedly connected to the upper surface of the mounting frame.

[0005] Furthermore, the installation frame is divided into a movable beam and a fixed frame, and the room body and the outer edge of the fixed frame are fixedly connected; the movable beam and the fixed frame are fixedly connected before the floor is covered on the upper surface of the installation frame.

[0006] Furthermore, the relative position of the movable beam and the fixed frame can be adjusted. When the movable beam and the fixed frame are fixedly connected, the outer edge of the movable beam is first pressed against the house body and then fixedly connected to the fixed frame.

[0007] Furthermore, the lock has a fixed section, which is fixedly connected to the lower surface of the floor. The two ends of the fixed section are respectively connected to the adjustment part and the fixing part, and the adjustment part adjusts the fixing part to generate a vertical downward force on the floor.

[0008] Furthermore, the adjustment portion is arranged opposite to the inspection surface and located at the edge of the lower surface of the mounting frame, so that the adjustment portion can be directly operated after the inspection surface is opened.

[0009] Furthermore, a vertical fixing portion is provided directly below the adjustment portion and opposite to the inspection surface. After the inspection surface is opened, the lock can be fixedly connected to the floor in a vertical direction through the vertical fixing portion.

[0010] An assembled bathroom floor and room body connection structure is also proposed, comprising a room body and a mounting frame, wherein the outer side of the mounting frame is fixedly connected to the room body, and the floor and cover are fixedly connected to the upper surface of the mounting frame.

[0011] Furthermore, the installation frame is a rectangular frame formed by splicing a fixed frame and a movable beam. The fixed frame is a door-shaped frame formed by splicing floor installation square tube 1, floor installation square tube 2 and floor installation square tube 3 in the first place. The movable beam is overlapped between floor installation square tube 1 and floor installation square tube 3 and is detachably connected to them.

[0012] Furthermore, the upper surfaces of square tube 1, floor mounting square tube 2, floor mounting square tube 3 and the movable beam are all inclined from the outer edge of the rectangular frame to the inner side to form inclined surface 1. The bottom of floor mounting square tube 3 is fixedly connected to the fixed inclined block, and inclined surface 2 of the fixed inclined block is symmetrical to inclined surface 1. The outer edge of the floor is folded inward to form an inclined side that matches inclined surface 1, and the floor is covered on inclined surface 1 formed on the upper surface of the rectangular frame through the inclined side.

[0013] Furthermore, a lock is fixedly connected to the bottom of the floor, and the lock has a fixed section, which is fixedly connected to the lower surface of the floor. The two ends of the fixed section are respectively connected to an adjustment part and a fixed part, and the adjustment part adjusts the fixed part to generate a vertical downward force on the floor.

[0014] The present invention has the following advantages:

[0015] 1. The floor forms a relatively fixed connection structure relationship with the room body through the installation frame, so that there is no fixed connection point on the upper surface of the floor, which well maintains the sealing of the floor and is very convenient for installation and disassembly.

[0016] 2. The floor and mounting frame are fixed together using a lock. Once the floor is attached to the mounting frame, applying a vertical downward force to the lock will cause the floor to move vertically downward, tightly attaching the floor to the mounting frame and achieving a secure connection between the two surfaces. The lock allows for a convenient and direct connection between the floor and mounting frame, eliminating the need for multiple screws on the floor. This connection method is quick and efficient.

[0017] 3. The floor is fixedly connected to the upper surface of the installation frame by directly operating the adjustment part in the external space of the room through the inspection surface, so that the installation operator can conveniently fix the floor when the internal space of the room is limited.

[0021] In order for those skilled in the art to fully implement the present invention, the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 3 As shown, a method for connecting an assembled bathroom floor to a room body is provided, wherein a mounting frame is provided to fix the room body (1) to the outer edge of the mounting frame; after the floor (89) is covered on the upper surface of the mounting frame, the bottom surface of the floor (89) is fixedly connected to the upper surface of the mounting frame. In this embodiment, the room body (1) and the outer edge of the mounting frame are first solid-melt welded, and the floor (89) is directly covered on the upper surface of the mounting frame. The upper surface of the mounting frame and the bottom surface of the floor (89) are fixedly connected. In this way, the floor (89) forms a relatively fixed connection structural relationship between the mounting frame and the room body (1), and there is no fixed connection point between the upper surface of the floor (89) and the room body (1) and the mounting frame. Compared with the prior art in which the floor (89) and the room body (1) are connected by multiple screws, the method provided in this embodiment makes the upper surface of the floor (89) free of any fixed connection point, thus maintaining the sealing of the floor (89) well and making installation and disassembly very convenient.

[0023] Since there may be processing errors between the internal space of the house body (1), the external dimensions of the floor (89), and the dimensions of the installation frame, the installation frame is divided into a movable beam (3) and a fixed frame (2). The outer edges of the house body (1) and the fixed frame (2) are fixedly connected; before the floor (89) is covered on the upper surface of the installation frame, the movable beam (3) and the fixed frame (2) are fixedly connected. In this way, there is no fixed connection relationship between the house body (1) and the movable beam (3), and the movable beam (3) can adjust its relative position relationship with the fixed frame (2) according to the actual size of the floor (89) to adapt to the random processing errors of the floor (89).

[0024] Generally, the relative position of the movable beam (3) and the fixed frame (2) can be adjusted. When the movable beam (3) and the fixed frame (2) are fixedly connected, the outer edge of the movable beam (3) is first brought close to the room body (1) and then fixedly connected to the fixed frame (2). In this way, the room body (1) and the outer edge of the entire installation frame can be in close contact, and the floor (89) has good sealing performance after being covered on the installation frame. In order to further improve the sealing performance between the room body (1), the floor (89) and the installation frame, a sealing treatment can be performed between the floor (89) and the installation frame.

[0025] Since, in this embodiment, after the floor (89) is covered on the upper surface of the mounting frame, the fixed connection between the floor (89) and the mounting frame is carried out between the bottom surface of the floor (89) and the upper surface of the mounting frame, the floor (89) is fixedly connected to the upper surface of the mounting frame by the lock after the floor (89) is covered on the upper surface of the mounting frame. The lock is fixedly connected to the lower surface of the floor (89). The lock can generate a vertical downward force on the floor (89) so that the floor (89) is fixedly connected to the upper surface of the mounting frame. Since the lock itself is fixedly connected to the lower surface of the floor (89), after the floor (89) is covered on the upper surface of the mounting frame, as long as a vertical downward force is applied to the lock, the floor (89) can be driven to move vertically downward, thereby tightly covering the floor (89) on the upper surface of the mounting frame, thereby achieving a fixed connection between the floor (89) and the upper surface of the mounting frame. The floor (89) and the mounting frame can be conveniently and directly fixedly connected by the lock, without the need for multiple screws on the floor (89). This connection method is fast and efficient.

[0026] The lock has a fixed section (139), which is fixedly connected to the lower surface of the floor (89). The two ends of the fixed section (139) are respectively connected to the adjustment part (138) and the fixed part (145). The adjustment part (138) adjusts the fixed part (145) to generate a vertical downward force on the floor (89). In this embodiment, the adjustment part (138) can drive the fixed part (145) to move horizontally first. After the fixed part (145) moves horizontally to a certain position, a corresponding vertical guide limit component can be set in the horizontal movement direction. After the vertical guide limit component contacts the fixed part (145), the fixed part (145) starts to move vertically downward. Since the fixed section (139) and the floor (89) are fixedly connected, the floor (89) is driven to move vertically downward accordingly, thereby tightly covering the floor (89) on the upper surface of the installation frame.

[0027] Due to the large number of functional components of the assembled toilet, its vertical space layout is very cramped. It is very difficult to adjust the adjustment part (138) of the lock directly in the space below the floor (89) due to the limited operating space. Therefore, in this embodiment, an inspection surface (11) is provided on one of the connection surfaces where the installation frame is fixedly connected to the room body (1), so that the inspection surface (11) is directly opposite to the adjustment part (138). By opening the inspection surface (11) and operating the adjustment part (138), the fixing part (145) is adjusted to generate a vertical downward force on the floor (89). In this way, the installation operator can directly operate the adjustment part (138) in the external space of the room body (1) through the inspection surface (11) to fix the floor (89) to the upper surface of the installation frame, which greatly facilitates the installation operator's operation in fixing the floor (89). Preferably, the adjustment part (138) is arranged directly opposite to the inspection surface (11) and located at the edge of the lower surface of the installation frame, so that the adjustment part (138) can be directly operated after opening the inspection surface (11).

[0028] The floor (89) is fixedly connected to the mounting frame under the adjustment and fixation of the lock, but the lock and the mounting frame are not fixedly connected in the vertical direction below the mounting frame inside the room (1). Therefore, after the floor (89) and the mounting frame are fixedly connected, the fixed section (139) is fixedly connected to the floor (89) in the vertical direction. In this embodiment, a vertical fixing portion (12) can be provided at the bottom of the fixed section (139), and the vertical fixing portion (12) is fixedly connected to the mounting point below the mounting frame and inside the room (1). In this way, the fixed section (139) is fixedly connected to the floor (89) in the vertical direction, further strengthening the stability of the connection between the floor (89) and the mounting frame and the room (1).

[0029] In order to further ensure the overall sealing and connection stability of the entire floor (89), after the floor (89) is covered on the upper surface of the mounting frame and before the floor (89) is fixedly connected to the upper surface of the mounting frame, the toilet (91) is integrally connected to the floor (89). In this embodiment, the connection between the toilet (91) and the floor (89) is fixed by solid solution welding, and the two can also be integrally formed.

[0030] By the above method, the room body (1) and the floor (89) are fixedly connected by the mounting frame, the floor (89) is fixedly connected to the mounting frame by the lock, the lock is operated by the inspection surface (11), and finally the lock is fixedly connected to the mounting point below the mounting frame by the vertical fixing portion (12). By adopting the above method, the room body (1) and the floor (89) and the mounting frame are finally fixedly connected as a whole, and there are no screw mounting holes on the upper surface of the floor (89) and between the toilet (91) and the floor (89), which well ensures the sealing of the floor (89) and the toilet (91). In addition, the fixed connection operation between the floor (89) and the mounting frame does not occupy the internal space of the room body (1), making the operation process convenient and efficient.

[0031] The following is an embodiment of an assembled bathroom floor and room body connection structure using the above method. The outer side of the mounting frame is fixedly connected to the room body (1), and the floor (89) and the cover are fixedly connected to the upper surface of the mounting frame. The outer shape of the mounting frame can be matched with the inner space outline of the room body (1). For example, if the inner space outline of the room body (1) is a rounded rectangle, since the mounting frame needs to be fixedly connected to the inner surface of the room body (1), the outer shape of the mounting frame is also matched to be a rounded rectangle.

[0032] In this embodiment, the installation frame is a rectangular frame formed by splicing a fixed frame (2) and a movable beam (3), wherein the fixed frame (2) is a door-shaped frame formed by splicing a first floor installation square tube (21), a second floor installation square tube (22), and a third floor installation square tube (23), and the movable beam (3) is overlapped between the first floor installation square tube (21) and the third floor installation square tube (23) and is detachably connected thereto. During installation, the outer edge of the door-shaped frame formed by splicing a first floor installation square tube (21), a second floor installation square tube (22), and a third floor installation square tube (23) is first fixedly connected to the inner surface of the room body (1), and the two are fixedly connected by solid-melt welding. During installation, the movable beam (3) is fixedly connected to the door-shaped frame opening after its outer side is brought into contact with the house body (1). The connection between the movable beam (3) and the door-shaped frame opening is detachable. When there is a certain deviation between the internal contour of the house body (1) and the external dimensions of the fixed frame (2), the internal contour of the house body (1) can be adapted by adjusting the connection position between the movable beam (3) and the door-shaped frame.

[0033] In this embodiment, the top ends of the floor mounting square tube 1 (21) and the floor mounting square tube 3 (23) are fixedly connected to the mounting lug 1 (24), and the movable beam (3) is fixedly connected to the mounting lug 1 (24). The mounting lug 1 (24) is vertically fixedly connected to the bottom of the top ends of the mounting square tube 1 (21) and the floor mounting square tube 3 (23), and a waist-shaped hole is opened in the mounting lug 1 (24) along the direction of the mounting square tube 1 (21) and the floor mounting square tube 3 (23). The movable beam (3) adjusts the connection position with the floor mounting square tube 1 (21) and the floor mounting square tube 3 (23) through the waist-shaped hole.

[0034] The upper surfaces of the floor mounting square tube 1 (21), the floor mounting square tube 2 (22), the floor mounting square tube 3 (23) and the movable beam (3) are all inclined from the outer edge of the rectangular frame to the inner side to form the inclined surface 1 (25). The bottom of the floor mounting square tube 3 (23) is fixedly connected to the fixed inclined block (5). The inclined surface 2 (51) of the fixed inclined block (5) is symmetrical with the inclined surface 1 (25). The outer edge of the floor (89) is folded inward to form an inclined side (26) matching the inclined surface 1 (25). The floor (89) is covered on the inclined surface 1 (25) formed on the upper surface of the rectangular frame through the inclined side (26). The inclined surface 1 (25) on the upper surface of the rectangular frame and the oblique side (26) of the floor (89) are in contact with each other. After the floor (89) is covered on the upper surface of the rectangular frame, when a vertical downward force is applied to the floor (89), the floor (89) and the upper surface of the rectangular frame can be more tightly connected through the mutual contact between the inclined surface 1 (25) and the oblique side (26) of the floor (89).

[0035] In order to apply a vertical downward force to the floor (89), the bottom of the floor (89) is also fixedly connected to a lock (13), wherein the lock (13) has a fixed section (139), and the fixed section (139) is fixedly connected to the lower surface of the floor (89). The two ends of the fixed section (139) are respectively connected to an adjusting portion (138) and a fixing portion (145), and the fixing portion (145) is adjusted by the adjusting portion (138) to generate a vertical downward force on the floor (89).

[0036] In this embodiment, the fixing section (139) and the bottom of the floor (89) are fixedly connected. When a vertical downward force is applied to the floor (89) through the adjusting portion (138) and the fixing portion (145), the fixing section (139) drives the floor (89) to move vertically downward, thereby fixing the floor (89) to the upper surface of the rectangular frame.

[0037] The adjusting portion (138) is a push-pull screw rod that passes through the interior of the fixed section (139), and the fixed portion (145) is a locking bevel block connected to one end of the push-pull screw rod. The locking bevel block has an inclined surface that matches the second inclined surface (51) of the fixed bevel block (5). By rotating the push-pull screw rod, the locking bevel block can be driven to move toward the fixed bevel block (5). Through the mutual contact between the second inclined surface (51) and the locking bevel block, the fixed section (139) generates a vertical downward force on the floor (89). In this embodiment, the adjustment end of the push-pull screw is arranged below the floor mounting square tube (21). The locking bevel block can be moved toward the fixed bevel block (5) by turning the push-pull screw with a screwdriver. The adjustment end of the push-pull screw can be directly operated outside the room (1) through the opened inspection surface (11), without occupying the limited internal space of the room (1). Moreover, the floor (89) can be directly fixed to the upper surface of the rectangular frame by adjusting the push-pull screw. The operation process is efficient and convenient, and avoids the tedious operation of fixing the floor (89) with multiple screws.

[0038] In this embodiment, the lock (13) has two groups, and the two fixed sections (139) penetrate the entire lower surface of the floor (89) and are fixedly connected thereto. A reinforcing rib (92) is also fixedly connected between the two fixed sections (139), and the reinforcing rib (92) is also fixedly connected to the lower surface of the floor (89). In this way, when the two fixed sections (139) move vertically downward, the vertical downward force received by the floor (89) can be more uniform through the reinforcing rib (92) to prevent deformation. At the same time, the fixed sections (139) and the reinforcing rib (92) also play a supporting role for the floor (89).

[0039] The floor (89) is fixedly connected to the mounting frame under the adjustment and fixation of the lock, but the lock and the mounting frame are not fixedly connected in the vertical direction inside the room body (1) and below the mounting frame. In this embodiment, the fixing section (139) is fixedly connected to the second mounting lug (4) near the first floor mounting square tube (21), and the second mounting lug (4) is used to fix the rectangular frame to the fixed position below by bolts.

[0040] Obviously, the above-described embodiments merely represent several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent. It should be noted that a person of ordinary skill in the art can make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be based on the appended claims.
