Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated housing technology, specifically a prefabricated housing structure. Background Technology
[0002] Prefabricated modular housing, also known as integrated housing, is a type of housing built using industrialized production methods. It involves prefabricating some or all of the housing components in a factory, transporting them to the construction site, and assembling the components using reliable connection methods. This type of housing is called industrialized housing or prefabricated housing. Prefabricated concrete structure housing is a type of concrete structure that uses prefabricated concrete components as the main components, which are assembled, connected, and combined with some cast-in-place concrete to form a concrete structure.
[0003] Existing prefabricated houses are mostly placed directly on the foundation during assembly, without connections between walls. This makes the houses prone to cracking due to environmental factors during later use. Furthermore, due to construction requirements, pre-installed connectors cannot be properly aligned when arranging houses with height differences, hindering construction. To address these issues, we offer a prefabricated house structure solution. Utility Model Content

The fixing ports A6 and the pouring chamber A5 are arranged in a "T" shape. The side walls of assembled wall A1 and assembled wall B2 are fixedly connected to the fixing ports A6. The blocking plates A7 are inserted into the blocking plates A7. The inner wall of the blocking plates A8 is on the same horizontal plane as the left side wall of assembled wall A1 and the right side wall of assembled wall B2. The setting of the blocking plates A8 reduces the amount of work that workers need to do to grind the protruding parts of the wall later.
[0026] Both ends of the sidewall of the limiting block 3 are fixedly connected to screws A9 inside the pouring chamber A5. The outer surface of the screws A9 is fitted with a limiting plate 10 inside the fixing port A6. The limiting plate 10 is T-shaped and has a through hole that engages with the screws A9. The outer surface of the screws A9 is rotatably connected to a fastening nut A11 near the outer wall of the limiting plate 10. After the sidewall of the assembly wall A1 contacts the sidewall of the assembly wall B2, the screws A9 pass through the pouring chamber A5 and enter the fixing port A6. The height between the assembly wall A1 and the assembly wall B2 is adjusted according to the construction requirements. The limiting plate 10 is then fitted over the screws A9, and one end of the limiting plate 10 is inserted into the pouring chamber A5. The fastening nut A11 fixes the limiting plate 10 in the fixing port A6. At this time, the limiting block 3 is in close contact with the limiting groove 4.

Both the barrier plate A8 and the barrier plate B21 can be removed from the assembly wall A1 and the assembly wall B2. The screw B14 enters the fixing groove 16. The fastening nut B18 is adjusted according to the height difference between the assembly wall A1 and the assembly wall B2 until the fastening nut B18 is tightly attached to the side wall of the contact block 15. The barrier plate B21 is inserted into the locking block B20 to close the fixing port B19. At this time, concrete is poured into the pouring chamber A5 and the pouring chamber B12 respectively to fix the position between the assembly wall A1 and the assembly wall B2.
[0029] Working principle: When this prefabricated house structure is in use, after the side wall of prefabricated wall A1 contacts the side wall of prefabricated wall B2, the screw A9 passes through the pouring chamber A5 and enters the fixing port A6. The height between prefabricated wall A1 and prefabricated wall B2 is adjusted according to construction requirements. The limiting plate 10 is then placed over the screw A9, and one end of the limiting plate 10 is inserted into the pouring chamber A5. The fastening nut A11 is tightened to fix the limiting plate 10 in the fixing port A6. At this time, the limiting block 3 is in close contact with the limiting groove 4. The barrier plate A8 is then inserted... Insert the locking block A7 to close the fixing port A6. At the same time, the screw B14 enters the fixing groove 16. Adjust the fastening nut B18 according to the height difference between the assembled wall A1 and the assembled wall B2 until the fastening nut B18 is tightly against the side wall of the contact block 15. Insert the barrier plate B21 into the locking block B20 to close the fixing port B19.
