Technical Field
[0001] This utility model relates to the field of external structure technology, specifically to an assembled prefabricated external structure. Background Technology
[0002] In architecture, an external structure refers to a structure attached to the exterior of a building to provide additional functionality or aesthetic effects. Examples include external balconies, awnings, and curtain wall systems. External structures can also serve as placement areas for air conditioner outdoor units, and are commonly used in daily life.
[0003] To enhance the decorative effect and meet the overall facade requirements in special areas such as air conditioning units, existing construction methods typically require a large number of special irregular-shaped formwork castings and decorative components to be assembled on-site. The process is quite complicated, the on-site casting and assembly process is time-consuming, the construction cycle is often difficult to control, resulting in extended construction period. Moreover, there is a lot of material waste during on-site processing and installation, making it difficult to effectively control costs. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated external structure that features advantages such as improved construction efficiency and cost control through prefabricated assembly. It solves the problems that traditional construction methods often require on-site casting and assembly of a large number of special irregular-shaped templates and decorative components, which are complex, time-consuming, and difficult to control, leading to extended construction periods. Furthermore, the on-site processing and installation process results in significant material waste and difficulty in effectively controlling costs.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated assembly structure, including a U-shaped frame, a connecting mechanism on the back of the U-shaped frame, a rear fixing plate placed on the back of the U-shaped frame, and at least two first placement strips on the upper surface of the fixing plate;
[0006] The connecting mechanism includes two first precast concrete slabs, four reinforcing bars, two interlocking rectangular blocks, a second precast concrete slab, a hoisting hole, two interlocking slots, and at least two second placement strips. The two first precast concrete slabs are fixed to the left and right sides of the back of the U-shaped frame with bolts. The four reinforcing bars are all located inside the left and right first precast concrete slabs. The two interlocking rectangular blocks are all located on opposite sides of the left and right first precast concrete slabs. The two interlocking slots are all opened on the left and right sides of the lower surface of the second precast concrete slab. The interlocking rectangular blocks are fixed inside the interlocking slots with concrete mortar.
[0007] By adopting this technical solution, construction efficiency can be improved and construction costs can be controlled through the connecting mechanism.
[0008] Furthermore, at least two of the second placement strips are disposed on the upper surface of the second precast concrete slab, and the lifting holes are opened on the upper surface of the second precast concrete slab.
[0009] By adopting this technical solution, the second placement strip is integrally formed by casting the concrete structure and the second precast concrete slab.
[0010] Furthermore, the upper and lower sides of the front of the U-shaped frame are fixed with connecting frames by bolts, and the air conditioning panel body is rotatably connected to the outside of the connecting frames. Fixing plates are fixed on the left and right sides of the lower side of the air conditioning panel body on the upper and lower sides, and the fixing plates are fixed to the front of the U-shaped frame by bolts.
[0011] By adopting this technical solution, the U-shaped frame can be made of metal, serving both a supporting and fixing function, as well as enhancing aesthetics.
[0012] Furthermore, the hoisting hole is located on the longitudinal centerline of the second precast concrete slab.
[0013] By adopting this technical solution, the second precast concrete slab can be easily hoisted through the hoisting hole.
[0014] Furthermore, the interlocking slots on the left and right sides are symmetrically distributed on the left and right sides of the longitudinal central axis of the first precast concrete slab.
[0015] By adopting this technical solution, the mating slots on the left and right sides can be slidably inserted into the outer side of the mating rectangular blocks on the left and right sides.
[0016] Furthermore, no fewer than two of the second placement strips are evenly distributed on the upper surface of the second precast concrete slab.
[0017] By adopting this technical solution, the outdoor unit of the air conditioner can be placed on the upper surface of at least two second placement strips, which facilitates drainage.
[0018] Furthermore, the fixing plate is a third precast concrete slab, and at least two of the first placement strips are evenly distributed on the upper surface of the fixing plate.
[0019] By adopting this technical solution, fixing the plate as a third precast concrete slab can improve construction efficiency.
[0020] Furthermore, the first placement strip and the fixing plate are designed to be cast as a single unit.
[0021] By adopting this technical solution, the outdoor unit of the air conditioner can be placed on the upper surface of no less than two first placement strips, which also facilitates drainage.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] During construction, this prefabricated external structure involves creating four holes on the outer side of the building to align with the back reinforcement bars of the left and right first precast concrete slabs. After drilling, the four reinforcement bars are inserted into these holes. Concrete mortar is applied to the outer side of the four reinforcement bars to secure one end inside the hole. This process ensures the left and right first precast concrete slabs remain balanced, allowing them to be fixed to the building's exterior wall. A U-shaped frame is then bolted to the front of the left and right first precast concrete slabs. A second precast concrete slab is placed between the opposite sides of the first precast concrete slabs, with the left and right interlocking slots inserted into the outer sides of the left and right interlocking rectangular blocks. Concrete mortar is used to fix the left and right interlocking rectangular blocks inside the interlocking slots. Two connecting frames are then fixed to the upper and lower sides of the front of the U-shaped frame. Finally, four fixing plates are used to bolt the upper and lower air conditioning panels to the front of the U-shaped frame. This prefabricated assembly method improves construction efficiency and controls construction costs. Attached Figure Description
