Description

Technical Field

[0001] This utility model relates to the field of modular building structure technology, and in particular to a concrete modular public toilet. Background Technology

[0002] Currently, outdoor public toilets, especially those built later or temporarily, mainly take the form of light steel structure prefabricated modular structures and precast concrete structures. While light steel structure toilets are lightweight and easy to assemble, they are prone to ground deformation and wall / roof corrosion after prolonged use, resulting in high maintenance costs. Furthermore, due to the limited thickness of the steel flooring, walking on light steel structure toilets often results in a strong hollow feeling accompanied by ground shaking, leading to a very poor user experience. Precast concrete structures effectively solve the shortcomings of light steel structures, but current concrete toilets generally require on-site foundation excavation, pipe laying, backfilling, and then tiling and finishing. This results in a large workload during assembly, requiring more workers and equipment, leading to higher construction costs and longer construction time. Utility Model Content

[0026] Example: See Figure 1 , Figure 2 as well as Figure 3 A modular concrete public toilet, comprising a base box, walls 1 and a roof 2.

[0027] The base box includes a concrete floor panel 3 and side panels 4 surrounding the floor panel 3. The floor panel 3 is located above the side panels 4 and is connected by several vertically arranged connecting steel bars 5. The lower end of each connecting steel bar 5 passes through the floor panel 3 and extends into the side panel 4, while its upper end extends upward to form a reinforcing bar. During factory prefabrication, anchoring holes are opened on the floor panel 3 and side panels 4 at the positions corresponding to the connecting steel bars. The connecting steel bars are inserted into the anchoring holes, which are then filled with concrete grout.

[0028] Several drainage holes are provided on the floor panel 3, and drainage branch pipes are installed in the drainage holes. In practice, a toilet mounting groove 6 is formed around the drainage hole corresponding to the toilet's installation position on the floor panel 3. During assembly, the toilet is installed in the toilet mounting groove 6, and the toilet's drain outlet is connected to the drainage branch pipe. A water supply hole is also provided on the floor panel 3 corresponding to each drainage hole, and a water supply branch pipe is pre-installed in each water supply hole, extending from the upper side of the floor panel 3. In practice, each water supply branch pipe is connected to an angle valve to facilitate connection to the toilet's water tank. To further improve the convenience of on-site installation, a connecting pipe is pre-embedded between the toilet installation groove 6 and the wall 1. One end of the connecting pipe is connected to the toilet installation groove 6, and the other end passes through the upper side of the floor panel 3. In this way, when installing the toilet, you only need to connect the toilet tank to the connecting pipe through the pipe, and then connect the toilet inlet to the connecting pipe to quickly complete the installation, without the need for subsequent decoration and construction, thus greatly improving the installation efficiency.

[0029] A main drainage pipe and a main water supply pipe are laid beneath the floor panel 3. The drainage branch pipes are connected to the main drainage pipe via connectors, and the main water supply pipe is connected to the branch water supply pipes via connectors. In practice, both the main drainage pipe and the main water supply pipe are fixedly connected to the underside of the floor panel 3 using pipe clamps. To improve the overall adaptability of the toilet, drainage pipe holes and water supply pipe holes are provided on the side panel 4. The free ends of the main drainage pipe and the main water supply pipe extend from the drainage pipe holes and the water supply pipe holes respectively, so as to facilitate connection with external water supply pipes and sewage pipes.

[0030] Both wall 1 and roof 2 are made of PC material. Roof 2 is detachably connected to wall 1, and adjacent walls 1 are also detachably connected. All four edges of roof 2 extend to the outer sides of the surrounding walls 1. During implementation, connecting ribs are pre-embedded in the upper part of wall 1, protruding from the upper side of wall 1. Connecting holes are provided on the lower side of roof 2 corresponding to the connecting ribs, through which the connecting ribs are inserted to connect with wall 1. To improve the stability of the entire toilet, the inner sides of adjacent walls 1 are connected by multiple L-shaped connectors distributed from top to bottom, with two plates of each L-shaped connector fixedly connected to the two walls 1 respectively. On the lower side of wall 1, corresponding to the position of the connecting ribs, insertion holes are pre-set. Wall 1 inserts the connecting ribs through these holes to connect with the base box. A sleeve is pre-set inside the insertion hole of wall 1. The diameter of the sleeve is larger than the diameter of the connecting rib, allowing for a clearance fit with the connecting rib. Adhesive is filled between the connecting rib and the sleeve. This effectively improves the connection stability between the wall 1 and the base box. A sealing gasket is provided between the lower side of the wall 1 and the floor panel 3.

[0031] Lifting holes 7 are provided at corresponding positions on the side panels 4 on both sides of the ground panel 3 to facilitate lifting during installation.

[0032] In the actual production process, the design is first carried out according to the needs, and then the various parts are processed in the factory and pre-assembled. After the assembly is completed, the interior of the toilet is decorated in the factory and then disassembled. After being transported to the site, only the ground needs to be leveled, and then the assembly and connection to the external water supply and sewage pipes can be carried out. There is no need for foundation excavation and other work, which can greatly improve the construction efficiency and reduce the construction cost.

[0033] The base box in this design uses a concrete structure, which offers excellent stability, effectively shielding and protecting pipes without any hollow areas, and also provides better durability. Furthermore, no foundation excavation is required during construction, making it more convenient and faster. The walls and roof are made of PC material, which is lighter, easier to assemble, easier to maintain, and lower in cost.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
