[0002] In the Modular Integrated Construction (MiC) construction project, concrete pouring is an important process of concrete MiC construction, which is directly related to the overall quality of the module. At present, in order to meet the needs of on-site assembly and connection between prefabricated MiC horizontal modules and improve the integrity and rigidity of the entire house, it is necessary to set a reserved groove at the top of the short-span beam column of the connected prefabricated horizontal module to embed the steel bars, and then pour concrete to complete the rigid connection of the two horizontal modules. However, since the reserved groove at the top of the beam column must pass through the beam-column node area, the transverse steel bars and stirrups of the beam and the longitudinal steel bars and stirrups of the column are arranged alternately. At present, in the concrete engineering construction, the grooves reserved at the top of the prefabricated beams and columns are made of fixed aluminum formwork or manually excavated later. In this construction method, the operation process of erecting and dismantling the formwork is relatively complicated, labor-intensive and time-consuming, and the turnover of the formwork is low, and the construction cost is high; in addition, the manual excavation of the grooves later is not only time-consuming and labor-intensive, but also increases the labor cost. Utility Model Content

[0004] The technical solution adopted by the utility model is: a foam molding structure with reserved grooves on the tops of beams and columns of a concrete prefabricated assembly house, comprising a concrete casting mold cavity for a unit module prefabricated assembly house surrounded by a beam mold, a column mold, a floor panel mold, a support rod, and an inclined support rod, wherein a steel cage and stirrups are pre-installed in the concrete casting mold cavity, and a long strip foam module is fixed in the concrete casting mold cavity on the tops of beams and columns of the spliced ​​unit module prefabricated assembly house, wherein the top of the long strip foam module is flush with the top of the concrete casting mold cavity on the tops of the beams and columns.

[0005] Furthermore, the elongated foam module comprises at least one spliced ​​foam brick cut out by a cutter and suitable for being placed in the mold cavity.

[0006] Furthermore, both sides and the bottom of the long strip foam module are surrounded by wire mesh, and the wire mesh is suspended on the steel cage.

[0007] Furthermore, the long strip foam module comprises a wire mesh slot bent into an open right-angle long slot and foaming glue sprayed in the wire mesh slot, and the wire mesh slot is suspended on the steel cage frame.

[0008] Furthermore, the elongated foam module comprises a combination of foamed glue and foam bricks.

[0009] Furthermore, the longitudinal section of the elongated foam module includes a rectangular surface or an arcuate surface, and the elongated foam module is provided with a space for avoiding gaps at the intersection and staggered positions of the steel bars at the top of the column.

[0010] Furthermore, the splicing method of the spliced ​​unit module prefabricated assembly house includes horizontal splicing and vertical splicing, and the long strip foam module includes a horizontal long strip foam module and a vertical long strip foam module.

[0011] Furthermore, the transversely elongated foam module or the longitudinally elongated foam module has a width of 50-150 mm, a height of 150-250 mm, and a length of 200-850 mm.

[0012] Furthermore, the beam mould, column mould and floor panel mould are made of aluminum alloy material.

[0013] The utility model sets a fixed long foam module in the concrete pouring mold cavity at the top of the beams and columns of the prefabricated assembly room, without the need for additional aluminum template design, thus reducing design time and saving costs, avoiding manual excavation after pouring, and saving manpower and material resources. When foam bricks are placed in the mold cavity, since the foam bricks are simple to make and convenient to construct, the factory can quickly prepare a large number of them after the size is determined. During construction, it is only necessary to arrange the foam bricks neatly in the mold cavity, which greatly reduces construction time and speeds up construction progress. When foam glue is sprayed in the wire mesh slot, construction is convenient, and the foam glue is easy and convenient to remove later, saving costs. BRIEF DESCRIPTION OF THE DRAWINGS
