Problems solved by technology

[0002] The prefabricated house includes multiple housing units, and the existing housing units are usually prefabricated PC components, which are then transported to the construction site, assembled on the construction site, and the joints are cast in-situ to form housing units, and then the housing units are combined As a prefabricated building, on the one hand, it affects the construction progress, and on the other hand, it cannot guarantee the strength and stability of the connection nodes; and the existing prefabricated houses, the assembly of different floors and the assembly between floors and foundations, have stability and strength. Poor problem; in addition, prefabricated houses usually include bedrooms, kitchens, bathrooms and living rooms. If each unit is a prefabricated structure, it cannot meet individual needs
[0003] Prefabricated concrete components play a very important role in improving the overall strength and stability of prefabricated houses. In the prior art, the combination of concrete and steel structures is usually used, but there are the following problems: the bearing capacity of existing steel structures is limited, and most The force is still partly borne by the concrete, which requires high concrete strength, which increases the cost of the component; the combination of the steel structure and the concrete is not strong, and the concrete and the steel structure are prone to peeling off, which affects the strength of the precast concrete component; in addition, the precast concrete component The connection mode or connection nodes between them affect the stability and strength of the overall structure of the house
The fast and convenient connection between the connection node and the prefabricated beam-column determines the production efficiency of the prefabricated house, but in the existing prefabricated house, the connection node between the beam-column is not firmly connected, and the construction method is complicated.
[0004] Prefabricated concrete slabs are prefabricated in factories and assembled on the existing construction site. Existing prefabricated concrete slabs usually include a concrete slab and a frame embedded in the concrete slab. The frame structure has problems of low strength or complicated processing operations, and prefabricated The board is inconvenient to be connected with other structures at the construction site, which reduces the construction efficiency

Embodiment 1

[0044] like figure 1 As shown, a prefabricated house based on prefabricated units includes kitchen 1, bedroom 2, bathroom 3 and living room 4. The kitchen 1, bedroom 2 and bathroom 3 all adopt prefabricated housing units, and the prefabricated housing units include prefabricated concrete Frame, the precast concrete frame includes a plurality of vertical precast concrete columns 5, the upper ends between adjacent precast concrete columns 5 are provided with horizontal precast concrete beams 6, the upper ends of the precast concrete beams 6 are provided with precast concrete floors 7, the precast concrete floors The 7th is provided with a stairway as required. The living room 4 includes a plurality of vertical positioning concrete columns 8 , and positioning concrete beams are arranged between the upper ends of the adjacent positioning concrete columns 8 .

[0045] The use method of this embodiment: the living room 4 usually has different requirements according to the area of ​...

Embodiment 2

[0047] This embodiment is basically the same as Embodiment 1, the difference is: as Figure 2-4 As shown, the upper and lower ends of the precast concrete column 5 are provided with a hollow square shell 9, each side wall of the square shell 9 is provided with through holes 10 and several connecting holes 11, the precast concrete column 5 and the precast concrete The ends of the beam 6 are provided with reserved exposed steel parts 12 and pre-embedded positioning steel plates 13 for positioning the reserved exposed steel parts 12. The reserved exposed steel parts 12 correspond to the connecting holes 11 of the corresponding side walls one by one. Both the concrete column 5 and the precast concrete beam 6 are pre-embedded with a shaft reinforcement cage 14. The shaft reinforcement cage 14 includes a main reinforcement 15 and a stirrup 16 set outside the main reinforcement 15. The part where the end of the main reinforcement 15 passes through the positioning steel plate 13 is res...

Embodiment 3

[0053] This embodiment is basically the same as Embodiment 2, the difference is: as Figure 5-9 As shown, the precast concrete column 5 is pre-embedded with column steel 20 along the axial direction, and the precast concrete beam 6 is pre-embedded with beam steel 21 along the axial direction. 20 and the side wall ends of the beam profile steel 21 are vertically welded and fixed with a connecting plate 22, the column profile steel 20 and the beam profile steel 21 can also be integrated with the connection plate 22, and the side wall ends of the column profile steel 20 and the beam profile steel 21 are vertically welded and fixed There is a connection plate 22, and the column steel 20 and the beam steel 21 can also be integrated with the connection plate 22. The outer side of the connection plate 22 is welded and fixed with a plurality of steel bar nodes 23, and the outer sides of the column steel 20 and the beam steel 21 are evenly spaced. A stirrup 16, the stirrup 16 is connec...
