Description

Technical Field

[0001] The present invention relates to the field of building technology, and particularly to an energy-saving and environment-friendly prefabricated building house. Background Art

[0002] Prefabricated buildings usually use precast components for on-site assembly, without casting walls on-site, which can save a large amount of on-site construction costs. The docking structure between wall panels of existing prefabricated buildings is not easy to install, and a relatively high hoisting space is required for the docking installation between wall panels. For example, the Chinese invention patent publication number is CN119466136A, and the patent name is an energy-saving prefabricated building, which specifically discloses that one side edge of a unit wall 4 is fixedly connected with a connecting ear 14, and the other side edge of the unit wall 4 is provided with an ear slot 15, and the ear slot 15 is adapted to the connecting ear 14. The corner 3 is a right angle. One side edge of the corner 3 is provided with an ear slot 15, and the other side edge is fixedly connected with a connecting ear 14. The corner 3 is connected to the connecting ear 14 on the unit wall 4 through the ear slot 15, and the corner 3 is connected to the ear slot 15 on another unit wall 4 through the connecting ear 14. In this technical solution, when installing between adjacent unit walls and between the corner and the unit wall, it is necessary to vertically displace the unit wall by at least the height of two unit walls to achieve installation. When using a hoisting device to hoist the unit wall, the hoisting height requirement is relatively high, and during construction, if the wall is hoisted to a relatively high height, the stability is poor. During the assembly operation, it is necessary to adjust the accuracy and stability of the wall hoisting position in real time, and the hoisting operation is relatively complex, which will directly affect the efficiency of wall assembly. Therefore, there is a problem of relatively low assembly efficiency in existing prefabricated buildings. Summary of the Invention

[0003] The purpose of the present invention is to provide an energy-saving and environment-friendly prefabricated building house to solve at least one of the above problems existing in the prior art.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] An energy-saving and environment-friendly prefabricated building house includes a bottom unit, multi-layer units, and a roof. A bottom plate is provided between the bottom unit and the multi-layer units. The bottom unit includes a first wall panel and a second wall panel. The two first wall panels are arranged opposite to each other, and the two second wall panels are arranged opposite to each other. Both sides of the lower end of the first wall panel are respectively provided with first L-shaped limiting parts bent upward, and both sides of the lower end of the second wall panel are respectively provided with first L-shaped notch parts docked with the first L-shaped limiting parts. The first L-shaped notch parts are docked with the corresponding first L-shaped limiting parts. Both sides of the upper end of the second wall panel are respectively provided with first positioning blocks extending radially towards the first wall panel. First positioning holes are provided at the four corner positions of the bottom plate. The first positioning blocks are docked and matched with the first positioning holes. Limiting ribs are symmetrically arranged on the upper end surface of the bottom plate;

[0006] The multi-layer unit includes a third wall panel and a fourth wall panel. The two third wall panels are arranged oppositely, and the two fourth wall panels are arranged oppositely. A limiting groove is provided at the lower end of the third wall panel, and the limiting groove is in butt joint and cooperation with a limiting rib. Second L-shaped limiting parts that are bent upward are respectively provided on both sides of the lower end of the third wall panel. Second L-shaped notch parts that are in butt joint with the second L-shaped limiting parts are respectively provided on both sides of the lower end of the fourth wall panel. The second L-shaped notch parts are in butt joint with the corresponding second L-shaped limiting parts. Second positioning blocks that radially extend towards the third wall panel are respectively provided on both sides of the upper end of the fourth wall panel. The roof includes a top cover and a connecting frame. Second positioning holes are provided at the four corner positions of the connecting frame. The second positioning blocks are in butt joint and cooperation with the second positioning holes. The top cover is arranged at the upper end of the connecting frame.

Also, since the four corner positions of the bottom plate are provided with first positioning holes, and the first positioning blocks are docked and matched with the first positioning holes, the first positioning blocks can also limit the bottom plate, thereby making the connection of the structure of this layer more stable; since the upper end surface of the bottom plate is symmetrically provided with limiting ridges, when installing the second-layer structure, the third wall panel is installed first. The lower end of the third wall panel is provided with a limiting groove, and the limiting groove is docked and matched with the limiting ridges, which can realize the rapid positioning of the third wall panel. Since the two sides of the lower end of the third wall panel are respectively provided with second L-shaped limiting parts bent upward, and the two sides of the lower end of the fourth wall panel are respectively provided with second L-shaped notch parts docked with the second L-shaped limiting parts, when the second L-shaped notch parts are docked with the corresponding second L-shaped limiting parts, during the preliminary installation and positioning of the third wall panel and the fourth wall panel, only the fourth wall panel needs to be slightly lifted to achieve the docking of the second L-shaped notch parts and the second L-shaped limiting parts, and the assembly of the third wall and the fourth wall can be efficiently realized; since the two sides of the upper end of the fourth wall panel are respectively provided with second positioning blocks extending radially towards the third wall panel, the second positioning blocks can limit the upper end of the third wall panel. Also, since the four corner positions of the connecting frame are provided with second positioning holes, and the second positioning blocks are docked and matched with the second positioning holes, the second positioning blocks can also limit the connecting frame, thereby making the connection of the top-layer structure more stable; finally, the roof is installed on the top-layer structure. In summary, for each layer structure of this technical solution, the positioning and installation of adjacent wall panels can be realized only by slightly lifting the adjacent wall panels, and its installation difficulty is greatly reduced and the installation efficiency can be improved.

[0008] Further, in order to ensure the flatness of the building appearance, when the first L-shaped notch part is docked with the first L-shaped limiting part, the two ends of the second wall panel are flush with the outer side surface of the first wall panel.

A plurality of connection holes are vertically provided on the side panel, and the connection holes are fixedly connected to the second wall through bolts.

[0013] Furthermore, in order to improve the reliability of the connection between the L-shaped reinforcing plate and the wall, the connection holes and the mounting holes are arranged in a staggered manner.
