Description

Technical Field

[0001] The present invention relates to the technical field of integral bathroom, and in particular, the present invention relates to a barrier-free splicing structure and installation method for an assembled bathroom floor bottom box. Background Art

[0002] With the introduction of energy conservation and emission reduction policies, the technology of prefabricated interior decoration has rapidly emerged, and the application of prefabricated floor bottom boxes is also increasing. Limited by the production process of the bottom box and transportation conditions, it is impossible to produce a single bottom box with a large-size modulus. Therefore, in a relatively large space of a bathroom unit, the prefabricated floor is composed of two or more bottom boxes spliced together. How to achieve barrier-free combined splicing that meets the waterproof requirements between the bottom boxes is an urgent problem to be solved at present.

[0003] Generally, the structure of a bathroom floor bottom box is relatively simple, usually composed of a bottom plate plus a square frame. For example, Chinese Patent CN211341567U discloses a bathroom laying module and a bathroom floor. The bathroom laying module includes a waterproof bottom box, and the waterproof bottom box includes a bottom plate and a frame sealed and installed on the edge of the bottom plate; floor tiles are attached to the bottom plate; a side strip is closed and located between the floor tiles and the frame, the inner edge of the side strip abuts against the outer edge of the floor tile, and the outer edge of the side strip abuts against the inner surface of the frame. The bathroom floor includes a water retaining strip and two bathroom laying modules, the two frames abut against each other, the first end of the water retaining strip abuts against one side of one side strip facing away from the bottom plate, and the second end of the water retaining strip bypasses the side facing away from the bottom plate of the two abutting frames and then abuts against one side of the other side strip facing away from the bottom plate. The frame disclosed in this patent is enclosed by four rectangular profiles. For the bottom box frame composed of such a simple rectangular profile frame, when the bottom box is filled with waterproof adhesive, the bonding performance between the rectangular profile frame and the waterproof adhesive is not strong enough, and the frame of the bottom box is easily loosened when subjected to external force, resulting in a gap between the bottom box and the waterproof adhesive layer filled inside it, leading to a decline in the waterproof performance of the bottom box.

[0004] In addition, the splicing between two adjacent bathroom laying modules is realized through a water retaining strip. The water retaining strip is in a U shape and is buckled upside down on the splicing perimeter of two adjacent bathroom modules. Adhesive is coated on the concave surface of the U-shaped water retaining strip. When splicing with this inverted water retaining strip, the amount of adhesive filled inside it is not easy to control and the adhesive is prone to partial overflow, which brings inconvenience to the gluing operation. On the other hand, this splicing method focuses on the horizontal splicing of two adjacent bathroom modules and ignores the vertical splicing of two adjacent bathroom modules, resulting in relatively weak splicing strength in the vertical direction between two adjacent bathroom modules, poor integrity of the two adjacent bathroom modules after splicing, and poor overall structural stability. When subjected to external force, the overall structure is prone to looseness or deformation and dislocation. Summary of the Invention

[0059] An embodiment of the present invention provides a barrier-free splicing structure for an assembled bathroom floor bottom box, and the structure is as Figures 1 to 8 shown.

The vertical direction connecting member includes an L-shaped vertical connecting member 4 and a vertical direction clamping member 5. The first bottom box frame 1 includes a first vertical direction splicing frame 101 and a first horizontal direction splicing frame 102 connected in an L shape; the first horizontal direction splicing frame 102 has a first L-shaped splicing portion, and the first L-shaped splicing portion has a first splicing horizontal plate 1024; the second bottom box frame 2 includes a second vertical direction splicing frame 201 and a second horizontal direction splicing frame 202 connected in an L shape; the second horizontal direction splicing frame 202 has a second L-shaped splicing portion, and the second L-shaped splicing portion has a second splicing horizontal plate 2024. One end of the second splicing horizontal plate 2024 abuts against one end of the first splicing horizontal plate 1024; the horizontal direction connecting member 3 covers the first splicing horizontal plate 1024 and the second splicing horizontal plate 2024 and connects the first splicing horizontal plate 1024 and the second splicing horizontal plate 2024 into one body.

[0060] The L-shaped vertical connecting member 4 is composed of a vertical connecting horizontal plate 401 and a first vertical connecting vertical plate 402; the lower side surface of the end of the first vertical direction splicing frame 101 and the lower side surface of the end of the second vertical direction splicing frame 201 abut against the upper side surface of the vertical connecting horizontal plate 401; the outer side surface of the end of the first vertical direction splicing frame 101 and the outer side surface of the end of the second vertical direction splicing frame 201 abut against the inner side surface of the first vertical connecting vertical plate 402. The vertical direction clamping member 5 includes a second vertical connecting vertical plate 501 and an L-shaped clamping plate 502, and a clamping groove 503 is formed between the second vertical connecting vertical plate 501 and the L-shaped clamping plate 502; the upper side surface of the end of the first vertical direction splicing frame 101, the upper side surface of the end of the second vertical direction splicing frame 201, and the upper side surface of the first vertical connecting vertical plate 402 are clamped into the clamping groove 503, and the inner side surface of the first vertical direction splicing frame 101 and the inner side surface of the second vertical direction splicing frame 201 abut against the outer side surface of the second vertical connecting vertical plate 501.

[0061] In the embodiment of the present invention, the inner side surface refers to the side surface located inside the bottom box frame, and the outer side surface refers to the side surface located outside the bottom box frame.

[0062] Preferably, the L-shaped clamping plate 502 is provided with a bending section approaching the second vertical connecting plate 501. The arrangement of this bending section enables the vertical clamping member 5 to limit the components clamped in its clamping groove 503, making the clamping more firm and not easily loosening or coming out.

[0063] The first bottom box frame 1 and the second bottom box frame 2 of the embodiments of the present invention are both in a rectangular structure. When two adjacent bottom boxes are spliced, the first vertical splicing frame 101 of the first bottom box frame 1 and the second vertical splicing frame 201 of the second bottom box frame 2 are connected into a whole by a vertical connecting member. Specifically, one end of the first vertical splicing frame 101 and one end of the second vertical splicing frame 201 are simultaneously clamped into the rectangular clamping groove formed by the L-shaped vertical connecting member 4 and the vertical clamping member 5. In addition, the first horizontal splicing frame 102 of the first bottom box frame 1 and the second horizontal splicing frame 202 of the second bottom box frame 2 are connected into a whole by a horizontal connecting member 3. Specifically, the horizontal connecting member 3 covers the first splicing cross plate 1024 and the second splicing cross plate 2024 and connects the first splicing cross plate 1024 and the second splicing cross plate 2024 into one body through an adhesive. During assembly, the polyurethane-based foaming glue is injected into the groove formed above the horizontal connecting member 3 to firmly bond the two adjacent bottom boxes into one body.

[0064] The barrier-free splicing structure of the sanitary ware prefabricated floor bottom box of the present invention splices two adjacent bottom boxes in the horizontal direction through the horizontal connecting member 3, and at the same time splices two adjacent bottom boxes in the vertical direction through the vertical connecting member. The barrier-free splicing structure of the sanitary ware prefabricated floor bottom box of the present invention realizes the synchronous splicing of two adjacent bottom boxes in the horizontal direction and the vertical direction. After splicing, the integrity of the bottom box structure is stronger, the overall structural stability is better, and the overall structure is not easily loosened or deformed and misaligned when subjected to external forces, and has better waterproof and sealing performance.

[0065] Preferably, the upper end surfaces of the first splicing cross plate 1024 and the second splicing cross plate 2024 are provided with a first clamping and limiting portion 103, and the lower end surface of the horizontal connecting member 3 is provided with a second clamping and limiting portion 301 that cooperates with the first clamping and limiting portion 103 for clamping. The overall connection between the horizontal connecting member 3 and the first splicing cross plate 1024 and the second splicing cross plate 2024 is realized through the clamping and limiting portion, and then the adhesive connection of the adhesive is supplemented to make the connection between them more stable and firm. More preferably, the first clamping and limiting portion 103 is serrated, and correspondingly, the second clamping and limiting portion 301 is also serrated.

[0066] Preferably, the first vertically spliced border 101 includes a border vertical plate 1011, a storage horizontal plate 1012, a first limiting vertical plate 1013, and a first Z-shaped reinforcing plate 1015. One end of the storage horizontal plate 1012 is vertically connected to the inner side surface of the border vertical plate 1011; the first limiting vertical plate 1013 is arranged parallel to the border vertical plate 1011; the other end of the storage horizontal plate 1012 is connected to the first limiting vertical plate 1013, and an upward-opening receiving groove 1014 is formed among the border vertical plate 1011, the storage horizontal plate 1012, and the first limiting vertical plate 1013, and the receiving groove 1014 is used for receiving the wall panel; the first Z-shaped reinforcing plate 1015 is connected to the inner side surface of the border vertical plate 1011, and the first Z-shaped reinforcing plate 1015 includes a first reinforcing horizontal plate 10151, a first reinforcing vertical plate 10152, and a second reinforcing horizontal plate 10153. The first reinforcing horizontal plate 10151 is arranged parallel to the storage horizontal plate 1012 and is located below the storage horizontal plate 1012. One end of the first reinforcing vertical plate 10152 is vertically connected to one end of the first reinforcing horizontal plate 10151. The second reinforcing horizontal plate 10153 is arranged parallel to the first reinforcing horizontal plate 10151; the other end of the first reinforcing vertical plate 10152 is vertically connected to one end of the second reinforcing horizontal plate 10153, and the other end of the second reinforcing horizontal plate 10153 is vertically connected to the border vertical plate 1011.

[0067] During use, after the bottom box border structure is formed, it is necessary to fill polyurethane-based foaming glue inside the border. While achieving adhesion to other structures, it realizes the waterproof sealing performance. Therefore, the firmness of the adhesion between the polyurethane-based foaming glue and the ground bottom box border structure is particularly important. Improving the firmness of the adhesion between the adhesive components can prevent the adhesive components from deforming under the influence of external forces and improve the waterproof sealing performance of the overall structure. The first reinforcing vertical plate 10152 of the first Z-shaped reinforcing plate 1015 can be adhesively bonded to the polyurethane-based foaming glue in the vertical direction, while the first reinforcing horizontal plate 10151 and the second reinforcing horizontal plate 10153 can be adhesively bonded to the polyurethane-based foaming glue in the horizontal direction. In this way, the firmness of the adhesion between the first vertically spliced border 101 and the polyurethane-based foaming glue in the horizontal and vertical directions can be improved simultaneously, preventing the formed bottom box border structure from being easily loosened when subjected to external forces and improving the waterproof performance of the bottom box.

[0068] In addition, since the lower side surface of the storage horizontal plate 1012, the outer surface of the first Z-shaped reinforcement plate 1015, and a part of the inner side surface of the frame vertical plate 1011 also need to be bonded to the polyurethane-based foaming adhesive, preferably, the lower side surface of the storage horizontal plate 1012, the outer surface of the first Z-shaped reinforcement plate 1015, and a part of the inner side surface of the frame vertical plate 1011 are designed into a non-planar structure. For example, the non-planar structure can be a plurality of continuous or discontinuous concave surfaces, and the concave surface can be an arc-shaped concave surface. In this way, compared with the planar structure, the non-planar structure design can increase the contact area between the lower side surface of the storage horizontal plate 1012, the outer surface of the first Z-shaped reinforcement plate 1015, and a part of the inner side surface of the frame vertical plate 1011 and the polyurethane-based foaming adhesive, thereby enhancing the bonding firmness between them. More preferably, the lower side surface of the storage horizontal plate 1012 and the outer surface of the first Z-shaped reinforcement plate 1015 are in a corrugated plate structure, and at least a part of the inner side surface of the frame vertical plate 1011 is also in a corrugated plate structure.

[0069] Preferably, the first limiting vertical plate 1013 is connected to the storage horizontal plate 1012 in a T shape. In this way, a receiving groove 1014 for receiving the wall panel is formed between the upper part of the first limiting vertical plate 1013, the storage horizontal plate 1012, and the frame vertical plate 1011. The protruding lower part of the first limiting vertical plate 1013 can be bonded to the adhesive, further improving the bonding firmness between the bottom box connector and the adhesive.

[0070] Preferably, the second vertically spliced frame 201 has the same structure as the first vertically spliced frame 101.

[0071] Preferably, the first horizontal direction splicing frame 102 includes a second limiting vertical plate 1021, an L-shaped connecting plate 1022, and a second Z-shaped reinforcing plate 1023. The L-shaped connecting plate 1022 includes a connecting horizontal plate 10221 and a connecting vertical plate 10222. The upper end of the connecting vertical plate 10222 is vertically connected to one end of the connecting horizontal plate 10221; the other end of the connecting horizontal plate 10221 is vertically connected to the second limiting vertical plate 1021, and the upper end surface of the second limiting vertical plate 1021 is higher than the upper end surface of the connecting horizontal plate 10221; the connecting vertical plate 10222 is arranged in parallel with the second limiting vertical plate 1021; one end of the first splicing horizontal plate 1024 is vertically connected to the lower end of the connecting vertical plate 10222; the first splicing horizontal plate 1024 and the connecting horizontal plate 10221 are respectively located on both sides of the connecting vertical plate 10222; the second Z-shaped reinforcing plate 1023 is connected to the inner side surface of the connecting vertical plate 10222. The second Z-shaped reinforcing plate 1023 includes a third reinforcing horizontal plate 10231, a second reinforcing vertical plate 10232, and a fourth reinforcing horizontal plate 10233. The third reinforcing horizontal plate 10231 is arranged in parallel with the connecting horizontal plate 10221. One end of the second reinforcing vertical plate 10232 is vertically connected to one end of the third reinforcing horizontal plate 10231. The fourth reinforcing horizontal plate 10233 is arranged in parallel with the third reinforcing horizontal plate 10231; the other end of the second reinforcing vertical plate 10232 is vertically connected to one end of the fourth reinforcing horizontal plate 10233; the other end of the fourth reinforcing horizontal plate 10233 is vertically connected to the connecting vertical plate 10222.

[0072] During use, after the bottom box frame structure is formed, it is necessary to fill the inside of the frame with polyurethane foam glue to achieve waterproof sealing performance while bonding with other structures. Therefore, the firmness of the bonding between the polyurethane foam glue and the ground bottom box frame structure is particularly important. Improving the firmness of the bonding between the bonding components can prevent the bonding components from deforming under the influence of external forces and improve the waterproof sealing performance of the overall structure. The second reinforcing vertical plate 10232 of the second Z-shaped reinforcing plate 1023 can be bonded to the polyurethane foam glue in the vertical direction, while the third reinforcing horizontal plate 10231 and the fourth reinforcing horizontal plate 10233 can be bonded to the polyurethane foam glue in the horizontal direction. The setting of the second Z-shaped reinforcing plate 1023 can significantly improve the firmness of the bonding between the bottom box frame structure and the polyurethane foam glue filled therein.

[0073] In addition, the lower side surface of the connecting horizontal plate 10221, a part of the inner side surface of the connecting vertical plate 10222, and the outer surface of the second Z-shaped reinforcing plate 1023 also need to be bonded to the polyurethane foam glue. The lower side surface of the connecting horizontal plate 10221, a part of the inner side surface of the connecting vertical plate 10222, and the outer surface of the second Z-shaped reinforcing plate 1023 are also designed into a non-planar structure. Preferably, the non-planar structure is a corrugated plate structure, which can increase the contact area between them and the polyurethane foam glue, thereby improving the bonding firmness.

[0074] Preferably, the second horizontally spliced border 202 has the same structure as the first horizontally spliced border 102.

[0075] Preferably, the second limiting vertical plate 1021 and the connecting horizontal plate 10221 are vertically connected in a T shape. In this way, the protruding lower part of the second limiting vertical plate 1021 can be bonded to the adhesive, further enhancing the firmness of the bonding between the bottom box border structure and the adhesive.

[0076] The embodiment of the present invention also provides an installation method for a barrier-free splicing structure of a bathroom prefabricated floor bottom box, including the following steps:
