[0018] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 8 The present invention provides a technical solution: Example 1: A prefabricated bathroom fixture with a modular assembly frame, comprising: a chassis outer frame 1 and a ceiling beam 3.

[0020] Specifically, a slotted square tube 11 is fixed on the upper surface of the outer frame 1 of the chassis. The slotted square tube 11 is located in the center of the upper surface of the outer frame 1 of the chassis, and the overall shape of the slotted square tube 11 is consistent with the overall shape of the outer frame 1 of the chassis, both being rectangular. At one corner of the outer frame 1 of the chassis, a right-angled groove is formed by inward contraction for the laying of water supply and drainage pipes. An assembled side wall 2 is set above the outer frame 1 of the chassis. The bottom of the assembled side wall 2 is provided with a slot corresponding to and adapted to the slotted square tube 11. The assembled side wall 2 is fixedly installed on the upper surface of the outer frame 1 of the chassis. Two adjacent assembled side walls 2 are fixedly spliced ​​by bolts, and a sealing strip is provided at the splice. The top of the assembled side wall 2 is fixed to the wall by corner brackets. After the assembled side wall 2 and the outer frame 1 of the chassis are assembled, a hollow three-dimensional structure is formed, which serves as the main structure of the bathroom. Secondly, the ceiling beam 3 is located above the middle of the outer frame 1 of the chassis. Both ends of the ceiling beam 3 are fixedly connected to the prefabricated side wall 2. A suspension clamp 4 is suspended below the ceiling beam 3. The suspension clamp 4 is perpendicular to the ceiling beam 3. The suspension clamp 4 is long and narrow, and both sides of the suspension clamp 4 are folded down 180 degrees and then bent down to form a symmetrical "J"-shaped clamping part 41. The two ends are in contact and pressing against each other. The structure of the suspension clamp 4 is as follows: Figure 5 and Figure 6 As shown, the suspension clamp 4 itself has a certain elastic deformation capability, and a buckle assembly 5 is provided below the suspension clamp 4; Furthermore, the buckle assembly 5 includes an aluminum alloy buckle plate 51, the two sides of which are folded upward to form symmetrical, inverted "J"-shaped hanging lock openings 52. The hanging lock openings 52 pass through two clamping parts 41 from bottom to top and are fastened to one clamping part 41, such as... Figure 6As shown, the side edges of two adjacent gusset plate assemblies 5 are attached to each other, and jointly pass from bottom to top between the two clamping portions 41. At this time, the two hanging locking notches 52 are symmetrical and exactly correspondingly fit with the two symmetrical clamping portions 41 respectively, so as to realize the hanging installation of the gusset plate assemblies 5. A waterproof layer 53 is fixed on the lower surface of the aluminum alloy gusset plate 51, and the waterproof layer 53 and the aluminum alloy gusset plate 51 are arranged in a staggered manner. A sealing gasket 56 is adhesively fixed at the exposed position of the upper surface of the waterproof layer 53. After the installation of a plurality of gusset plate assemblies 5 is completed, the joint between two adjacent aluminum alloy gusset plates 51 and the joint between two adjacent waterproof layers 53 can be staggered from each other. The aluminum alloy gusset plate 51 and the waterproof layer 53 each cover the joint of the other, and with the arrangement of the sealing gasket 56, the sealing performance of the entire bathroom suspended ceiling can be effectively improved, preventing electrical components and circuits in the suspended ceiling from being damaged by moisture.

[0021] For the installation of the waterproof layer 53, the present application is further provided with positioning holes 55 penetrating through both the aluminum alloy gusset plate 51 and the waterproof layer 53, and the two are fixed by bolts. A decorative layer 54 is fixed on the lower surface of the waterproof layer 53, and the waterproof layer 53 and the aluminum alloy gusset plate 51 can be kept relatively fixed, so as to avoid falling off. The decorative layer 54 can be used to decorate the lower surface of the waterproof layer 53 and cover the bolts, improving the aesthetic appearance.

[0022] To ensure the positional stability of the hanging fixtures 4, a plurality of ceiling cross beams 3 and a plurality of hanging fixtures 4 in the present application are both arranged at equal intervals, and a well-shaped distribution is formed between the plurality of ceiling cross beams 3 and the plurality of hanging fixtures 4, so as to adapt to the installation of the plurality of gusset plate assemblies 5 below. The ceiling cross beams 3 and the hanging fixtures 4 are kept suspended and fixed therebetween by hanging members 31, so that the position of the hanging fixtures 4 themselves can remain stable.

[0023] For the hanging installation of the hanging fixtures 4, the hanging member 31 in the present application is configured as a "C" shape with a downward opening. The hanging member 31 is buckled on the outer side of the ceiling cross beam 3 and fixed by bolts. The hanging member 31 can be buckled onto the ceiling cross beam 3 from top to bottom. The overall height dimension of the hanging member 31 is larger than the height dimension of the ceiling cross beam 3, so that the lower end of the hanging member 31 can extend below the ceiling cross beam 3. The lower end of the hanging member 31 is configured as a symmetrical, horizontal "C"-shaped hanging hook 32 and buckled on the outer side of the hanging fixture 4. The hanging hook 32 is mainly used to cooperate with the hanging fixture 4 to perform hanging installation and fixation of the hanging fixture 4. Since the hanging fixture 4 itself has a certain elastic deformation capability, a large friction force can be generated between the folded portion of the hanging fixture 4 and the hanging hook 32, so as to avoid relative sliding between the hanging fixture 4 and the hanging member 31. In addition, according to actual requirements, bolts or screws may be further provided between the hanging fixture 4 and the ceiling cross beam 3 for locking and positioning, which will not be elaborated here.

[0024] In order to improve the stability of the ceiling beam 3, the present application is further provided with suspension rods 6 above both ends of the ceiling beam 3. The upper ends of the suspension rods 6 are anchored to the wall top, the lower ends of the suspension rods 6 are provided with suspension frames 61, and the suspension frames 61 are sleeved on the outer side of the ceiling beam 3 and fixed by bolts. The suspension rods 6 are mainly used for suspending both ends of the ceiling beam 3 to improve the installation stability of the ceiling beam 3. The relative position between the suspension frame 61 and the ceiling beam 3 is adjustable, so as to optimize the force distribution of the hanging points between the suspension rods 6 and the ceiling beam 3.

[0025] In order to adjust the height position of the ceiling beam 3, the present application is further provided with a square-shaped hollow frame 62 fixed on the upper surface of the suspension frame 61. The lower end of the suspension rod 6 movably penetrates through the top plate of the hollow frame 62, and is threadedly sleeved with two adjusting nuts 63. The two adjusting nuts 63 are respectively pressed against the upper and lower surfaces of the top plate of the hollow frame 62. The arrangement of the hollow frame 62 and the adjusting nuts 63 can be used to adjust the distance between the lower end of the suspension rod 6 and the suspension frame 61, so as to adjust the height position of the ceiling beam 3 according to the actual height position of the wall top.

[0026] For supplementary description of the chassis outer frame 1, the present application is further provided with a polyurethane chassis 12 fixed inside the chassis outer frame 1, which corresponds to and fits the chassis outer frame 1. The polyurethane chassis 12 and the chassis outer frame 1 are reinforced and fixed by reinforcing angle irons 14. Floor tiles 13 are attached to the upper surface of the polyurethane chassis 12, and a gap is reserved between the edge of the floor tile 13 and the chassis outer frame 1. The floor tiles 13 and the polyurethane chassis 12 form the floor of the bathroom, and grout is filled between adjacent floor tiles 13.

[0027] For supplementary description of the structure of the prefabricated side wall 2, the prefabricated side wall 2 of the present application includes a double-layer keel frame 21, which is used to improve the overall thickness and strength of the prefabricated side wall 2. A gap is reserved between the two layers of keel frames 21, cushion blocks are padded between the two layers of keel frames 21, and they are fixedly connected by screws. Polyurethane wall panels 22 are fixed on both side surfaces of the prefabricated side wall 2. A bathroom wall tile 23 is attached to the surface of one polyurethane wall panel 22, and the lower end of the bathroom wall tile 23 is inserted into the gap between the floor tile 13 and the chassis outer frame 1. The bathroom wall tile 23 is located on the inner side surface of the entire prefabricated side wall 2, that is, the inner space of the bathroom. The edge of the floor tile 13 and the lower part of the bathroom wall tile 23 form a paving method of "floor pressing wall", which makes the construction more convenient. The surface of the other polyurethane wall panel 22 is fixed with an outer facing layer 25, and the arrangement of the outer facing layer 25 is used to improve the aesthetics.

[0028] To reinforce the corner, this application also includes a water supply pipe 24 installed between the two layers of the keel frame 21 to facilitate the supply of water to the bathroom interior. A corner profile 26 is installed between two adjacent prefabricated side walls 2 at the corner. A continuous square tube 27 is embedded between the corner profile 26 and the keel frame 21, and the continuous square tube 27 is used to lock and fix the keel frame 21 and the corner profile 26 together with self-tapping screws 28. The corner profile 26 is used to reinforce the two adjacent prefabricated side walls 2 at the corner. Furthermore, as... Figure 8 As shown, at the inside corner, two adjacent bathroom wall tiles 23 are pressed together in one direction to form a joint, and the joint is filled with sealant; in contrast, at the outside corner, splicing can be achieved by existing known begonia corners or 45-degree bevel cuts, which will not be elaborated here.
