Description

Technical Field

[0001] The invention relates to the technical field of splicing buildings, in particular to a mutual connection structure between an outer wall of a module house and a concrete floor. Background Art

[0002] As a new model of prefabricated building development, container houses play an important role in rapid construction. At present, the conventional practice is to assemble the enclosure wall panels after the ground is completed. The wall panels are directly located on the concrete floor. The connection node between the wall and the concrete floor will form a through seam. After the sealant is applied, there is often a certain risk of water seepage.

[0003] The bottom of the existing enclosure structure is located on the concrete floor, forming a horizontal seam, which poses a risk of water seepage into the interior. The commonly used method is to manually apply glue in the gap to achieve the purpose of waterproofing. This method is time-consuming and labor-intensive, and the quality cannot be guaranteed. Summary of the invention

[0004] The purpose of the present invention is to provide an interconnection structure between the outer wall of a modular house and a concrete floor, wherein an L-shaped angle iron is welded to a bottom steel beam in advance and extends indoors by a distance equal to the thickness of a retaining wall panel. After pouring the ground concrete, the retaining wall panel is directly seated on the L-shaped angle iron during installation. The horizontal gap formed in this way is below the concrete floor and is located on the L-shaped angle iron, thereby achieving an effective waterproof function from a structural point of view.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A mutual connection structure between the outer wall of a modular house and a concrete floor, comprising a steel beam, a concrete floor and a surrounding wall panel, wherein the top of the steel beam is fixedly connected with an L-shaped angle iron, the surrounding wall panel is located on the top of the L-shaped angle iron, the bottom of the L-shaped angle iron and one side of the steel beam are fixedly connected with a transverse sliding bar, the inner surfaces of two transverse sliding bars are slidably connected with a first sliding block, the inner surfaces of two first sliding blocks are rotatably connected with a first rotating block, and a bracing assembly for supporting the L-shaped angle iron is arranged between opposite sides of the two first rotating blocks;

[0007] The support assembly includes opposing threaded rods that are respectively located on two first rotating blocks and are threadedly arranged opposite to each other. The outer surfaces of the two opposing threaded rods are threadedly connected with tension nuts. The opposite sides of the two tension nuts are fixedly connected with fixing plates. A rotating cylinder is arranged between the outer surfaces of the two tension nuts.

[0008] As a further solution of the present invention: the top and the bottom of the rotating cylinder are both provided with limiting holes, and the inner surface of the limiting hole is matched with the outer surface of the tension nut.

[0009] As a further solution of the present invention: a connecting spring for tightening the tension nut is fixedly connected between opposite sides of the two fixing plates.

[0010] As a further solution of the present invention: a tightening assembly for tightening the enclosing wallboard is provided between the top of the steel beam and one side of the enclosing wallboard;

[0011] The tightening assembly includes two sliding rails located on the steel beam and the surrounding wall panel, the inner surfaces of the two sliding rails are slidably connected to the second sliding blocks, the inner surfaces of the two second sliding blocks are rotatably connected to the second rotating blocks, the opposite sides of the two second rotating blocks are fixedly connected to the tension threaded rods, the outer surfaces of the two tension threaded rods are fixedly connected to the connecting plates, and a plurality of sliding rods are arranged between the opposite sides of the two connecting plates.

[0012] As a further solution of the present invention: a plurality of sliding holes are provided on the outer surface of the connecting plate, and the inner surfaces of the sliding holes are slidably connected to the outer surface of the connecting plate.

[0013] Beneficial effects of the present invention:

[0014] (1) In the present invention, the L-shaped angle iron is welded to the bottom steel beam in advance and extends indoors by the thickness of the enclosure wall panel. After the ground concrete is poured, the enclosure wall panel is directly seated on the L-shaped angle iron during installation. The horizontal gap formed in this way is below the concrete floor and located on the L-shaped angle iron, which can achieve an effective waterproof function from a structural point of view.

[0015] (2) In the present invention, a first sliding block is provided on the L-shaped angle iron and the steel beam, and a first rotating block that can rotate in the first sliding block is utilized. When the rotating cylinder is rotated, the two opposing threaded rods are rotated, so that the two opposing threaded rods can move to a side that is relatively close to or relatively far away from each other, thereby supporting the portion of the L-shaped angle iron that extends beyond the steel beam, and a tightening assembly is provided between the steel beam and the enclosure wall panel. The sliding rail and the second sliding block in the tightening assembly are utilized in conjunction with the tightening nuts on the tensioning threaded rods. When the sliding rod is rotated, the two tensioning threaded rods can move to an opposite side, thereby tightening the tightening assembly, thereby preventing the enclosure wall panel from tilting and causing a gap to appear between the enclosure wall panel and the L-shaped angle iron, thereby further improving its practicality.

A connecting spring 76 for tightening the tensioning nuts 74 is fixedly connected between the opposite sides of the two fixing plates 75. The connecting spring 76 can prevent the two tensioning nuts 74 from falling into the interior of the rotating cylinder 72. By arranging a first sliding block 5 on the L-shaped angle iron 2 and the steel beam 1 and utilizing a first rotating block 6 that can rotate inside the first sliding block 5, when the rotating cylinder 72 is rotated, the two opposing threaded rods 71 ​​are rotated, thereby enabling the two opposing threaded rods 71 ​​to move to a side that is relatively close to or relatively far away from each other, thereby supporting the portion of the L-shaped angle iron 2 that extends beyond the steel beam 1.

[0026] A tightening assembly 8 for tightening the enclosing wall panel 4 is provided between the top of the steel beam 1 and one side of the enclosing wall panel 4;
