[0038] As Figures 1 to 5 shown, the present embodiment provides an assembled house framework, which comprises a frame profile 1, a structural plate body 2, a connecting square tube 3 and a butt joint cross beam 4.

[0039] The top of the frame section 1 is provided with a square slot 101, and the inner side of the frame section 1 is provided with a horizontal beam sleeve slot 102 with an inner side opening, one end of the butt joint horizontal beam 4 can be vertically sleeved in the horizontal beam sleeve slot 102, and the upper side of the horizontal beam sleeve slot 102 is provided with a clearance slot 103;

[0040] The side of the structural plate body 2 is provided with a square recess 201;

[0041] The width of the square slot 101 and the square recess 201 is equal to that of the connecting square 3, and the depth is half of the thickness of the connecting square 3.

[0042] The square slot 101, the connecting square 3 and the square recess 201 can be butt jointed in sequence to realize the quick splicing between the frame section 1 and the structural plate body 2, and the two structural plate bodies 2 can also be butt jointed by vertically inserting the connecting square 3 into the square recess 201 to realize the building of the house wall plate.

[0043] The frame sections 1 on the two sides of the frame as the side frame are connected by the butt joint horizontal beam 4 to realize the building of the house base. The reverse buckling of the base structure on the top can also be used as the roof. The floor must be laid on the butt joint horizontal beam 4 on the bottom to form a plane to facilitate use and isolate the external ground. In order to ensure the connection stability, after the butt joint horizontal beam 4 is inserted into the horizontal beam sleeve slot 102, the locking bolt 401 can be inserted downward at the bottom of the clearance slot 103 to avoid the loosening of the frame section 1 under stress.

[0044] In addition, the clearance slot 103 can provide a layout channel for water and electricity pipelines.

[0045] The inner side of the square slot 101 and the square recess 201 is provided with a clamping protrusion 5. The protruding clamping protrusion 5 limits and clamps the connecting square 3 when it is inserted into the square slot 101 and the square recess 201 to form an interference fit, which can improve the connection stability and avoid structural loosening.

[0046] The outer side of the frame section 1 is provided with a joint slot 6, the joint slot 6 is fixedly sleeved with a positioning tab 7, and the two adjacent frame sections 1 are fixedly connected through the positioning tab 7. The joint slot 6 is arranged at both ends of the horizontal beam sleeve slot 102, and the positioning tab 7 is connected with the frame section 1 through a positioning bolt 701. Since the house is generally square, the two frame sections 1 need to be cut at a 45° inner bevel angle at the right angle. At this time, the L-shaped positioning tab 7 is sleeved into the joint slot 6 of the two end frame sections 1 to complete the positioning butt joint at the corner. The positioning bolt 701 can strengthen the butt joint stability of the connection point to avoid structural loosening. In addition, the design of integrating the joint slot 6 at both ends of the horizontal beam sleeve slot 102 helps to control the size of the frame section 1 and reduce the manufacturing cost of the parts.

[0047] The frame section 1 is provided with a keel slot 104, and the reinforcing keel 8 is connected in series in the keel slot 104, and a plurality of frame sections 1 can be connected in series on the reinforcing keel 8. When the frame section 1 needs higher strength or needs to be extended, the reinforcing keel 8 can be inserted, and various housing design schemes can be adapted.

[0048] The thickness of the frame section 1 is greater than the thickness of the structural plate body 2. When the structural plate body 2 is vertically fixed on the frame section 1 through the cooperation of the square bar clamping groove 101, the connecting square bar 3 and the square bar groove 201, the frame section 1 with a thickness greater than the structural plate body 2 can stably bear the weight of the structural plate body 2, and the structural stability is high.

[0049] The height of the frame section 1 is greater than the sum of the height of the butt joint cross beam 4 and the thickness of the structural plate body 2, and the cross beam sleeve groove 102 is arranged at the bottom of the inner side of the frame section 1. After the frame section 1 is installed at both ends of the butt joint cross beam 4, the structural plate body 2 can be clamped in the pit formed by the two frame sections 1 and the butt joint cross beam 4 in the middle as a floor. Since the structural plate body 2 as a floor is inlaid in the inner side of the frame section 1, the alignment of the structural plate body 2 is facilitated, and the installation is fast and stable.

[0050] The outer side of the frame section 1 is provided with a support arc surface 105 which is inwardly tapered from top to bottom. The support arc surface 105 can improve the impact resistance of the frame section 1, avoid deformation of the frame section 1 under stress, and improve the structural stability.

[0051] The outer side of the frame section 1 and the outer side of the adjacent structural plate body 2 are provided with a sealing strip (not shown in the figure). Since the joint is fixed by the connecting square bar 3, the sealing performance of the wall and the frame section 1 can be significantly improved after the sealing strip is applied on the outer side, and air and rain leakage can be avoided.

[0052] The above is a further detailed description of the present application in combination with a specific preferred embodiment, and the specific implementation of the present application cannot be limited to these descriptions. Any changes and modifications made within the scope of the present application should still be included in the scope of the present application.
