Description

Technical Field

[0001] The utility model belongs to the technical field of industrialized production of buildings, and in particular relates to a self-locking connection structure between columns for modular steel structures. Background Art

[0002] Modular steel structure refers to the construction of buildings in a modular assembly method based on industrialized construction production. The system usually prefabricates the entire room as the basic module unit in the factory, and can arrange and decorate the interior space of the room. It is then transported to the construction site and hoisted to reliably connect the module units to form the overall structure of the building. It has the advantages of energy saving and environmental protection, fast construction speed, and a high degree of industrialization.

[0003] In order to give full play to the advantages of rapid on-site installation of modular steel structures, the structural skeleton, maintenance wall panels and various pipelines in the basic modular units are prefabricated in the factory and then transported to the site for assembly. Adjacent units of existing modular steel structures are usually connected only at the corners of the modular units, and there is no connection between the parallel modular unit components. Compared with the "one column and multiple beams" connection form in traditional steel structures, the "four columns and eight beams" connection form will appear in modular buildings, resulting in the phenomenon of "column separation" between the four columns. There is no connection between the parallel modular unit components, and it is impossible to form a coordinated force. The overall structure has poor integrity, low bearing capacity, large steel consumption, and high cost, which seriously restricts the promotion and application of modular building steel structures in the construction market.

[0031] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figures 1 to 7 As shown, the utility model provides a self-locking connection structure between columns for modular steel structures, and the self-locking connection structure includes:

[0042] A further optimized solution is that the self-locking part includes two first slide grooves 411 opened on the bottom wall of the circular groove 49, the two first slide grooves 411 are horizontally and symmetrically arranged, the first slide grooves 411 and the diameter of the circular groove 49 are colinear, the two first slide grooves 411 are connected to the U-shaped groove 410, a sliding lock tongue 44 is slidably connected in the first slide groove 411, a small reset spring 46 is fixedly connected between the sliding lock tongue 44 and the bottom wall of the first slide groove 411, the side of the sliding lock tongue 44 away from the small reset spring 46 extends out of the first slide groove 411 and is clamped with the U-shaped connecting piece 3, the side of the sliding lock tongue 44 away from the first slide groove 411 is fixedly connected with a first lever, and the first lever is slidably connected in the rotating part.

[0043] After the sliding locking tongue 44 is engaged with the U-shaped connecting piece 3 , the small reset spring 46 is in a stretched state, the large reset spring 45 is in a compressed state, and the elastic force of the large reset spring 45 is much greater than that of the small reset spring 46 .

[0044] A further optimized solution is that the rotating part includes three third slide grooves 413 opened on the rotating wheel 47, the three third slide grooves 413 are arranged at equal intervals in the circumferential direction, the three third slide grooves 413 are slidingly connected to the two first levers and the second lever respectively, and a through groove is opened on the outer edge of the rotating wheel 47, the through groove is colinear with the diameter of the rotating wheel 47, and the through groove is connected to the third slide groove 413 slidingly connected to the second lever.

[0045] According to a further optimized solution, the limiting portion includes a screw hole provided on the top surface of the first connecting plate 41 , an unlocking bolt 42 is threadedly connected to the screw hole, and the bottom end of the unlocking bolt 42 passes through the screw hole and abuts against the slider 43 .

[0046] The unlocking bolt 42 is installed or removed by the wrench 5 .

[0047] A further optimized solution is that the first protrusions 32 are fixedly connected to the opposite sides of the U-shaped connecting member 3, and the second protrusions 33 are fixedly connected to the bottom end of the U-shaped connecting member 3. The first protrusions 32 and the second protrusions 33 are both slidably connected to the U-shaped groove 410. A limiting hole 31 is provided on the side wall of the first protrusion 32. The limiting hole 31 is correspondingly arranged to the first sliding groove 411, and the limiting hole 31 is clamped with the sliding lock tongue 44.

[0048] The working process of the utility model is as follows:

[0049] Reference Figure 5 to Figure 6 As described above, the U-shaped groove 410 is inserted into the first protrusion 32 of the U-shaped connector 3. As the installation proceeds, when the sliding lock tongue 44 contacts the first protrusion 32, the inclined surface of the sliding lock tongue 44 is pressed to move inward, and the first lever drives the rotating wheel 47 to rotate clockwise, while driving the slider 43 to move downward;

[0050] When the sliding lock tongue 44 is aligned with the limiting hole 31, due to the presence of the large return spring 45, the slider 43 is pushed upward and abuts against the bottom end of the unlocking bolt 42. At the same time, the slider 43 causes the second lever to drive the rotating wheel 47 to rotate counterclockwise, thereby driving the sliding lock tongue 44 to enter the limiting hole 31 to achieve the connection process. In the connection process, the utility model only needs to align the U-shaped groove 410 of the self-locking connection component 4 and insert it into the first protrusion 32, and no additional operation process is required.

[0051] When unlocking is required after the connection process is completed, refer to Figure 7 , use the wrench 5 to unscrew the unlocking bolt 42 on the top of the modular unit, the slider is no longer constrained by the unlocking bolt 42, and continues to move upward due to the action of the large reset spring 45, the slider 43 slides out of the through slot and out of the range of the rotating wheel 47, and the rotation of the rotating wheel 47 is only affected by the small reset spring 46. Since the small reset spring 46 is in a stretched state, the small reset spring drives the sliding lock tongue 44 to retract and disengage from the limiting hole 31, thereby achieving unlocking.

[0052] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0053] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
