Detailed Implementation
[0029] The present application will be further described below with reference to specific embodiments and accompanying drawings.
[0030] Example
[0031] refer to Figures 1-3 As shown, a prefabricated assembly stacked box includes an upper box cover 1 and a lower box body 2. The downward-facing opening of the upper box cover 1 is provided with a connector 3 or a slot 4, and the upward-facing opening of the lower box body 2 is provided with a slot 4 or a connector 3. The upper box cover 1 and the lower box body 2 are assembled into a complete and closed stacked box by splicing and matching the connector 3 and the slot 4. That is, the stacked box is composed of two pieces, upper and lower, which are connected by pre-reserved slots on the side walls of the upper box cover and the lower box body to form a whole.
[0032] Both the upper cover 1 and the lower box 2 are precast reinforced concrete structures. The upper cover 1 and the lower box 2 have a cuboid outline, and the assembled box also has a cuboid outline. The cuboid structure of the assembled box is suitable for most scenarios. The height of the upper cover 1 is 1 / 4 to 5 / 12 of the height of the assembled box, and the height of the lower box 2 is 7 / 12 to 3 / 4 of the height of the assembled box. That is, the upper cover 1 is the smaller structure, and the lower box 2 is the larger structure.
[0033] The upper cover 1 includes a precast reinforced concrete top plate 12 and an upper cover side wall 13, which enclose a certain space, thus forming a downward-facing opening. The lower box body 2 includes a precast reinforced concrete bottom plate 14 and a lower box side wall 15, which enclose a certain space, thus forming an upward-facing opening. The height of the box body can be adjusted by adjusting the height of the side wall plates during prefabrication.
[0034] The socket 3 has a rectangular cross-section, and the socket 4 has a rectangular cross-section. The two form a matching socket structure to achieve mutual alignment between the upper and lower parts, so as to ensure the accuracy of the splicing. In addition, a concave-convex water-stop structure is formed at the splicing position, which can improve the sealing of the stacked box and ensure the overall waterproof effect.
[0035] The socket 3 is annular and located at the outer edge of the upper box cover 1, and the slot 4 is annular and located at the outer edge of the lower box body 2. Then, the rectangular annular socket 3 is inserted into the rectangular annular slot 4 to assemble the stacked box on-site, achieving stable splicing and preventing slippage. Similarly, the socket 3 can also be located on the lower box body 2, and the corresponding slot 4 is located on the upper box cover 1.
[0036] On the four side surfaces of the top of the upper box cover 1, there are upper cover shear teeth 5, and on the four side surfaces of the bottom of the lower box body 2, there are lower box shear teeth 8. There are several shear teeth, which are evenly arranged at the same height along the side surface. The shear teeth adopt a groove with a serrated structure to better connect the box body with the cast-in-place structure to form an integral whole.
[0037] On the top surface of the top of the upper box cover 1, there are upper cover lifting rings 6, and on the side surface of the bottom of the lower box body 2, there are lower box lifting rings 9. There are four lifting rings on the top surface or side surface respectively. The lifting rings are made of round steel and are embedded into the precast components to meet the bearing requirements during hoisting, improving construction efficiency and safety.
[0038] On the top of the upper box cover 1, there are upper cover embedded bars 7 extending out of the top surface, and on the bottom of the lower box body 2, there are lower box embedded bars 10 extending out of the side surface. The upper cover embedded bars 7 and the lower box embedded bars 10 are both L-shaped structures, and at least three columns of embedded steel bars are arranged. The embedded steel bars are tied to the floor steel bars to form an integral stress structure through concrete pouring, improving the shear resistance performance.
[0039] Inside the lower box body 2, there are stiffeners 11 that support along the transverse, longitudinal, and vertical directions. The horizontal cross-section of the stiffener 11 is in a grid shape, and the vertical cross-section of the stiffener 11 is in a shape like the Chinese character '艹'. The stiffening rib plates are evenly arranged to improve the overall stiffness and bearing capacity of the box body. On the lower box bottom plate 14 of the lower box body 2, drain holes are reserved for draining the accumulated water during construction.
[0040] The working process of this application:
[0041] (1) Fabrication of the lower box body: It is formed by concrete pouring, with internal stiffeners, shear teeth and continuous grooves are provided around.
[0042] (2) Fabrication of the upper box cover: Similarly, it is precast with concrete, shear teeth are set and bent steel bars are embedded, and continuous protrusions are provided on the bottom surface.
[0043] (3) Splicing and installation: After placing the lower box body in place through the lifting rings, slowly lower the upper box cover and align it with the groove, so that the continuous protrusions are accurately fitted with the continuous grooves.
[0044] (4) Overall pouring: Connect the shear teeth and the embedded bent steel bars with the adjacent beam and slab steel bars, and then comprehensively pour after the box body forms an integral structure with the entire floor slab, improving the overall stiffness and shear bearing capacity. [[ID=二十八]] [[ID=二十九]]
[0045] This embodiment, through reasonable structural design, achieves significant improvements in shear force transfer, load-bearing capacity, and ease of hoisting of prefabricated stacked boxes, meeting the needs of modern prefabricated buildings for efficient, safe, and economical structural components, and has broad application prospects.
[0046] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.
[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
