Description

Technical Field

[0001] The utility model belongs to the technical field of box construction, in particular to a concrete box system. Background Art

[0002] Containerized integrated buildings are constructed by breaking down individual buildings into boxes based on spatial structure, apartment layout, and functional zoning. These boxes are then prefabricated in a factory and transported to the construction site for installation. The resulting building entity meets safety, reliability, and relevant functional requirements. Compared to traditional construction methods, containerized integrated construction offers advantages such as high efficiency, resource conservation, environmental friendliness, and civilized construction.

[0003] Load-bearing walls and other main structures will be set between adjacent box units. The lateral force resisting wall structure has the characteristics of good overall performance, high rigidity and small lateral deformation under horizontal action. It is widely used in load-bearing walls. The box-type concrete box uses concrete wall formwork as the on-site concrete pouring formwork to make lateral force resisting walls, and uses beam formwork as the on-site concrete pouring formwork to make beam formwork, which greatly reduces the on-site formwork and internal decoration time, and minimizes the impact on surrounding residents.

[0004] However, wall formwork and beam formwork do not participate in the load-bearing process, so the thickness of the wall formwork and beam formwork will not be counted into the specified concrete thickness when pouring concrete, thus occupying a certain area of ​​the room. In addition, the steel bars of the wall formwork and beam formwork need to be tied on site, the formwork needs to be supported, the concrete needs to be poured, and workers of various professional trades need to construct in sequence, resulting in shortcomings such as a long construction period and more on-site operations. At the same time, there are also problems such as loss of materials such as formwork and a large amount of construction waste. Utility Model Content

[0055] The upper side slab 6 is a precast concrete composite slab with pre-embedded bottom reinforcement and upwardly projecting second angle frame bars 61, approximately 60 mm thick. Before the two concrete box layers are vertically spliced, the bottom reinforcement is mortised into the lateral force-resisting walls and beams. Concrete is then poured to embed the protruding second angle frame bars 61 and the bottom reinforcement, thus connecting the upper side slab 6 to the lateral force-resisting walls and beams. This forms a floor slab connected to the lateral force-resisting walls and beams. The final floor slab thickness is approximately 130 mm.

Cast all the boxes in the same concrete box layer that have been in place into a whole, then hoist the boxes in the upper box layer, and splice the upper boxes. When the upper box is in place, the first longitudinal force reinforcement 31 below is inserted into the corresponding grouting sleeve 32 in the first lateral force resisting wall 3 above, and the upper and lower connecting reinforcements 97 are inserted into the corresponding second lateral force resisting wall 9.

[0086] S7: Connect all the second longitudinal main reinforcements 94 and all the third longitudinal main reinforcements 98 corresponding to the upper and lower layers through the connecting sleeves 95.
