Description

Technical Field

[0001] This utility model belongs to the technical field of cold-formed thin-walled steel prefabricated steel structure building, specifically relating to a connection structure between lightweight walls and lightweight floors. Background Technology

[0002] When connecting cold-formed thin-walled steel sections in prefabricated buildings to lightweight walls and floors, self-tapping screws are typically used as the primary connection method. However, this method presents several problems: 1. On-site workers need relevant professional construction experience, such as knowing the appropriate nailing intervals and number of nails. 2. Components using existing connection methods may be damaged during recycling. 3. The numerous, dense, and complex connection nodes result in a long on-site construction cycle. 4. Existing connection methods and connectors require a certain amount of open workspace for module-to-module connections, hindering maximum prefabrication and integration of modules.

[0003] In view of this, this solution was developed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a connection structure between a lightweight wall and a lightweight floor, which reduces damage to the light steel components, greatly enhances the shear and tensile strength, and reduces the loss of recycled components.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a connection structure between a lightweight wall and a lightweight floor, including a first floor beam, a second floor beam, a wall connecting frame, and connectors. The first floor beam is located between two second floor beams, and the length direction of the first floor beam is perpendicular to the length direction of the second floor beam. The wall connecting frame is attached to the second floor beam. One side of the column on the wall connection has a connecting groove. The connector includes a connecting plate and a rotating member. The connecting plate is L-shaped, one side of the connecting plate is attached to the bottom of the connecting groove, and the other side of the connecting plate is attached to the side of the connecting groove near the second floor beam. The rotating member passes through the connecting plate, the first floor beam, and the second floor beam for connection.

[0006] Furthermore, there are multiple connectors, which are spaced vertically apart.

[0007] Furthermore, the rotating component is a bolt, a threaded hole is formed on the surface of the connecting plate, a raised ring is formed at the inner edge of the threaded hole, and an internal thread that matches the threaded hole is formed on the inner circumferential surface of the raised ring.

[0008] Furthermore, the first floor beam has a first mounting groove, and the second floor beam has a second mounting groove. The second mounting groove faces the first floor beam, and both ends of the first floor beam extend into the second mounting groove. The upper and lower ends are connected by screws passing through the second floor beam and extending into the side wall of the first floor beam.

[0009] Furthermore, there are multiple first floor slab beams, which are spaced apart.

[0010] Furthermore, there are two rotating parts, and the connecting plate and the bottom of the connecting groove are connected by the rotating parts.

[0011] Furthermore, the wall connection frame includes multiple columns, a top beam, and a middle beam. The middle beam has multiple vertically penetrating clearance notches. Two columns are located at the two ends of the middle beam and can be detachably connected. The remaining columns extend from the clearance notches, and the upper ends of the multiple columns are detachably connected to the top beam.

[0012] Furthermore, the lower surface of the top beam has a third mounting groove, and the upper end of the column extends into the third mounting groove and the two are laterally detachably connected.

[0013] Furthermore, both ends of the central beam extend into the connecting groove and are laterally detachable and connectable.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In this invention, a second floor beam is placed between the first floor beam and the wall connecting frame, which acts as a shim. A connecting plate and a screw are installed in the connecting groove on the column of the wall connecting frame. The screw passes through the wall connecting frame, the second floor beam, and the first floor beam to achieve fixation. The connecting plate is L-shaped, with its two sides fitting against the bottom and side surfaces of the connecting groove, respectively. This arrangement provides the connector with a certain degree of seismic resistance. Furthermore, this design changes the traditional self-tapping screw connection of the light steel structure to a bolt connection more suitable for steel structures, reducing damage to the light steel components (first floor beam, second floor beam, wall connecting frame), greatly enhancing shear and tensile strength, reducing losses during the recycling of light steel components, improving work efficiency, and reducing errors.

[0017] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0018] like Figures 1-3 As shown, this embodiment provides a connection structure between a lightweight wall and a lightweight floor, including a first floor beam 1, a second floor beam 2, a wall connection frame 3, and a connector 4.

[0019] There are multiple first floor beams 1. Each first floor beam 1 has a first mounting groove, and each second floor beam 2 has a second mounting groove. The second mounting grooves face the first floor beam 1. The first floor beam 1 is located between the two second floor beams 2. The length direction of the first floor beam 1 is perpendicular to the length direction of the second floor beam 2. Both ends of the first floor beam 1 extend into the second mounting grooves, and the upper and lower ends are connected by screws passing through the second floor beams 2 and extending into the side wall of the first floor beam 1. In this solution, the connection is achieved by bolts 42 and nuts.

[0020] The wall connecting frame 3 is attached to the second floor beam 2. Specifically, the wall connecting frame 3 includes multiple columns 31, a top beam 32, and a middle beam 33. The columns 31 have connecting grooves on their sides, and the middle beam 33 has multiple vertical clearance notches. Two columns 31 are located at the two ends of the middle beam 33 and can be detachably connected. Specifically, the two ends of the middle beam 33 extend into the connecting grooves and are laterally connected by screws or bolts 42. The remaining columns 31 extend from the clearance notches, and the upper ends of the multiple columns 31 are detachably connected to the top beam 32. Specifically, the lower surface of the top beam 32 has a third mounting groove, and the upper ends of the columns 31 extend into the third mounting groove and are laterally connected by screws or bolts 42 and nuts.

[0021] The connector 4 includes a connecting plate 41 and two screws. The connecting plate 41 is L-shaped. One side of the connecting plate 41 is in contact with the bottom of the connecting groove, and the other side of the connecting plate 41 is in contact with the side of the connecting groove near the second floor beam 2. One screw passes through the connecting plate 41, the first floor beam 1, and the second floor beam 2 for connection, and the other screw passes through the other end of the connecting plate 41 for connection with the bottom of the connecting groove. Specifically, the screws include bolts 42. The surface of the connecting plate 41 has two threaded holes. One threaded hole is used to connect with the second floor beam 2, and the other threaded hole is used to connect with the bottom of the connecting groove. A convex ring 411 is formed at the inner edge of the threaded hole. The inner circumferential surface of the convex ring 411 has an internal thread that matches the threaded hole. The convex ring 411 is formed by stamping.

[0022] In this design, a second floor beam 2 is placed between the first floor beam 1 and the wall connecting frame 3, which acts as a shim. Then, a connecting plate 41 and a screw are installed in the connecting groove on the column 31 of the wall connecting frame 3. The screw passes through the wall connecting frame 3, the second floor beam 2, and the first floor beam 1 to achieve fixation. The connecting plate 41 is L-shaped and its two sides are respectively attached to the bottom and side surfaces of the connecting groove. This arrangement gives the connecting piece 4 a certain seismic resistance. Moreover, this design changes the self-tapping screw connection of the traditional light steel structure to a bolt 42 connection that is more in line with the steel structure, reducing damage to the light steel components (first floor beam 1, second floor beam 2, and wall connecting frame 3), greatly enhancing shear and tensile strength, reducing the loss of recycled light steel components, improving work efficiency, and reducing errors.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
