Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a connection structure between cold-formed thin-walled steel composite walls. Background Technology
[0002] With the development of prefabricated buildings, thin-walled steel composite walls are increasingly being used in engineering construction. Current thin-walled steel composite walls mainly consist of two side columns, two thin steel plates, a joist between the two steel plates, and lightweight concrete filling. To facilitate faster assembly into houses, most current steel composite walls are mass-produced in factories. To improve the overall rigidity and strength of the wall, the side columns and joists are mostly formed using cold bending processes, making it impossible to form connecting components on the side columns. This results in secondary processing of the wall on-site when connecting wall panels, leading to lower efficiency in wall connection processing. Utility Model Content
[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a connection structure between cold-formed thin-walled steel composite walls, which can quickly realize the connection between walls, improve the connection efficiency, and ensure the strength and stability of the wall connection.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a connection structure between cold-formed thin-walled steel composite walls, including a first composite wall and a second composite wall, both of which include side columns; characterized in that: the side column includes two C-shaped steels, wherein the opening side of one C-shaped steel faces the inner side of the first composite wall or the second composite wall, and the opening side of the other C-shaped steel faces the outer side of the first composite wall or the second composite wall, and the base plates of the two C-shaped steels are welded and fixed; a U-shaped connector is provided in the outer-facing C-shaped steel of the side column of the first composite wall and the second composite wall, the base plate of the U-shaped connector is fixedly connected to the base plate of the C-shaped steel, and the free sides of the two side plates of the U-shaped connector extend out of the C-shaped steel; The two side plates of the U-shaped connector on the first composite wall have protruding teeth in opposite directions, and the two side plates of the U-shaped connector on the second composite wall have raised grooves in opposite directions. The two side plates of the U-shaped connector on the first composite wall extend into the U-shaped connector on the second composite wall, and the protruding teeth on the outer side of the two side plates of the U-shaped connector on the first composite wall are engaged in the grooves on the inner side of the two side plates of the U-shaped connector on the second composite wall, forming a one-way locking structure.
[0005] Furthermore, the U-shaped connector is connected to the base plate of the two C-shaped steels by self-tapping screws; and the two side plates of the U-shaped connector abut against the bent sections of the two wing plates of the C-shaped steel plates.
[0006] Furthermore, concrete is filled in the cavity formed by the two U-shaped connectors and the cavity formed by the U-shaped connectors, the outer side, and the inner side of the C-shaped steel.
[0007] Furthermore, the protruding teeth and the tooth grooves are formed by stamping the side plates of the U-shaped connector, and the side of the protruding teeth near the bottom plate of the U-shaped connector is a flat surface and the other side is an inclined surface. Correspondingly, the side of the tooth groove near the bottom plate of the U-shaped connector is an inclined surface and the other side is a flat surface.
[0008] Furthermore, both the protruding teeth and the grooves are located on the portion of the U-shaped connector that extends out of the C-shaped steel.
[0009] Furthermore, the length direction of the U-shaped connector is consistent with the length direction of the C-shaped steel, and its two ends are flush with the two ends of the C-shaped steel.
[0010] Furthermore, when the first composite wall and the second composite wall are arranged in an L-shape, the side plate of the U-shaped connector on the first composite wall near the inner side of the two composite walls bends and extends towards the second composite wall, and the protrusions on the side plate are located on the bent section; the side plates of the U-shaped connector on the first composite wall and the second composite wall near the outer side of the two composite walls are inclined in opposite directions; the two side plates of the U-shaped connector on the first composite wall extend into the U-shaped connector on the second composite wall and are connected by the engagement of the grooves and the protrusions.
[0011] Furthermore, it also includes a third composite wall, located on one side of the first and second composite walls, so that the first, second, and third composite walls are arranged in a T-shape. In this case, the two side plates of the U-shaped connector on the third composite wall are bent and extended in opposite directions, and the protrusions on the two side plates are located on the bent sections.

The other side plate of the U-shaped connector on the first and second composite walls is extended and connected by the engagement of the tooth groove and the protrusion.
[0012] Furthermore, it also includes a third composite wall and a fourth composite wall, which are located on both sides of the first and second composite walls, respectively, so that the first, second, third, and fourth composite walls are arranged in a cross shape.

[0023] Example 1: See Figure 1A connection structure between cold-formed thin-walled steel composite walls includes a first composite wall 1 and a second composite wall 2. Both the first composite wall 1 and the second composite wall 2 include two side columns 3, which are respectively located near the two sides of the first composite wall 1 and the second composite wall 2. In implementation, both the first composite wall 1 and the second composite wall 2 include two lightweight metal (such as light steel) side panels, with two side columns 3 vertically positioned between the side panels. The cavity formed by the side panels and the side columns 3 is filled with lightweight concrete. In this implementation, the side columns 3 include two C-shaped steel sections, each including a base plate and two wing plates. The free sides of the two wing plates are bent inwards towards the C-shaped steel sections and extend to form bent ends. One C-shaped steel has its opening facing the inside of either the first composite wall 1 or the second composite wall 2, while the other C-shaped steel has its opening facing the outside of either the first composite wall 1 or the second composite wall 2. The base plates of both C-shaped steels are welded and fixed. The flanges of both C-shaped steels are fixedly connected to the side panels using self-tapping screws. A U-shaped connector 4 is installed inside the outward-facing C-shaped steel of the side post 3 of the first composite wall 1 and the second composite wall 2. The base plate of the U-shaped connector 4 is fixedly connected to the base plate of the C-shaped steel, and the free sides of the two side plates of the U-shaped connector 4 extend out of the C-shaped steel. In practice, the length direction of the U-shaped connector 4 is consistent with the length direction of the C-shaped steel, and its two ends are flush with the two ends of the C-shaped steel. The base plate of the U-shaped connector 4 is connected to the base plates of the two C-shaped steels using self-tapping screws 5; this facilitates assembly and provides good stability. Furthermore, the two side plates of the U-shaped connector 4 abut against the bent sections of the two flanges of the C-shaped steel plate, thus restricting the position of the side plates of the U-shaped connector 4 and preventing large deformations. The cavities formed by the two U-shaped connectors 4 and the cavities formed by the U-shaped connectors 4 and their outer sides and the inner sides of the C-shaped steel are both filled with (lightweight) concrete. This results in a higher overall structural strength and better stability for the first composite wall 1 and the second composite wall 2. To facilitate the flow of the (lightweight) concrete, several through holes are vertically distributed on the portions of the U-shaped connectors 4 located inside the C-shaped steel. During implementation, a cover plate is also installed in the groove formed between the bent sections of the two C-shaped steels to seal the groove, thus ensuring a smooth surface after the first composite wall 1 and the second composite wall 2 are connected.
[0024] The U-shaped connector 4 on the first composite wall 1 has two side plates with protruding teeth 6 in opposite directions. The U-shaped connector 4 on the second composite wall 2 has two side plates with raised grooves in opposite directions. The two side plates of the U-shaped connector 4 on the first composite wall 1 extend into the U-shaped connector 4 on the second composite wall 2, and the protruding teeth 6 on the outer side of the two side plates of the U-shaped connector 4 on the first composite wall 1 engage with the grooves on the inner side of the two side plates of the U-shaped connector 4 on the second composite wall 2, forming a one-way locking structure. The protruding teeth 6 and the grooves are both located on the portion of the U-shaped connector 4 extending beyond the C-shaped steel to ensure that the connection between the two U-shaped connectors 4 is not affected by the C-shaped steel. In implementation, the U-shaped connector 4 is cold-bent / stamped / die-cast from a metal plate (steel plate, aluminum alloy plate, etc.), resulting in higher overall strength and a certain degree of elasticity, facilitating assembly and connection between them. In one implementation, the protruding teeth 6 and the toothed grooves are stamped from the side plates of the U-shaped connector 4. The protruding teeth 6 have a flat surface on one side near the bottom plate of the U-shaped connector 4 and an inclined surface on the other. Correspondingly, the toothed grooves have an inclined surface on one side near the bottom plate of the U-shaped connector 4 and a flat surface on the other. Thus, the protruding teeth 6 and toothed grooves on the two U-shaped connectors 4 cooperate to form a unidirectional ratchet structure, ensuring stability. That is, when the two composite walls approach each other, the protruding teeth 6 and toothed grooves on the two composite walls can gradually mate together, but due to the restriction of the protruding teeth 6 and toothed grooves, the two composite walls cannot move in a direction away from each other.
[0025] In this embodiment, see Figure 2 The first composite wall 1 and the second composite wall 2 are arranged in a straight line. The two side plates of the U-shaped connector 4 on the first composite wall 1 extend into the two side plates of the U-shaped connector 4 on the second composite wall 2 and are connected by the engagement of the protruding teeth 6 and the tooth groove.
[0026] Example 2, see Figure 3 Unlike Embodiment 1, when the first composite wall 1 and the second composite wall 2 are arranged in an L-shape, the side plate of the U-shaped connector 4 on the first composite wall 1, near the inner side of the two composite wall bodies, bends and extends towards the second composite wall 2, with the protruding teeth 6 on this side plate located on the bent section. The side plates of the U-shaped connector 4 on the first composite wall 1 and the second composite wall 2, near the outer side of the two composite wall bodies, are inclined in opposite directions. The two side plates of the U-shaped connector 4 on the second composite wall 2 are fitted onto the outer side plates of the two side plates of the U-shaped connector 4 on the first composite wall 1, and are connected by the engagement of the teeth and protruding teeth 6.
[0027] Example 3, see Figure 4Based on Embodiment 1, a third composite wall 7 is also included, located on one side of the first composite wall 1 and the second composite wall 2, so that the first composite wall 1, the second composite wall 2, and the third composite wall 7 are arranged in a T-shape. The two side plates of the U-shaped connector 4 on the third composite wall 7 are bent and extended in opposite directions, and the protrusions 6 on the two side plates are located on the bent sections. One side plate of the U-shaped connector 4 on the first composite wall 1 and the second composite wall 2 is located outside the side plate of the U-shaped connector 4 on the third composite wall 7, and is connected to the protrusions 6 through a groove. The other side plate of the U-shaped connector 4 on the first composite wall 1 and the second composite wall 2 is extended and connected to the protrusions 6 through a groove.
[0028] Example 4, see Figure 5 Based on Embodiment 1, the system further includes a third composite wall 7 and a fourth composite wall 8. The third composite wall 7 and the fourth composite wall 8 are located on opposite sides of the first composite wall 1 and the second composite wall 2, forming a cross-shaped distribution of the first composite wall 1, the second composite wall 2, the third composite wall 7, and the fourth composite wall 8. The side plates of the U-shaped connectors 4 on the third composite wall 7 and the fourth composite wall 8 are bent and extended in opposite directions, with the protruding teeth 6 on the side plates of both U-shaped connectors 4 located on the bent sections. The side plates of the U-shaped connectors 4 on the first composite wall 1 and the second composite wall 2 are located outside the side plates of the U-shaped connectors 4 on the third composite wall 7 and the fourth composite wall 8, respectively, and are connected by the engagement of the grooves and the protruding teeth 6.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
