Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of light steel keel frames, specifically to a plug-in type light steel keel frame. Background Technology
[0002] In the construction industry, the keel frame is a key material for supporting the shape and stabilizing the structure. Due to its characteristics, light steel keel has become a commonly used component for building keel frames. Multiple light steel keels can be spliced together to build a keel frame that meets the requirements. Currently, light steel keels with a U-shaped longitudinal section are widely used in actual construction. Their splicing method is relatively conventional. Construction workers will insert one end of one light steel keel directly into the end of another light steel keel and then tighten it with bolts.
[0003] However, after extensive practical observation, the inventors discovered that this splicing method has obvious drawbacks. In actual use, building structures are often affected by vertical stress. The light steel keel using the above splicing method has insufficient strength at the joints. Under stress, it is very easy for it to misalign with each other, which in turn affects the stability of the entire keel frame structure.
[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0007] A pair of light steel keels and a rectangular frame, wherein the rectangular frame is inserted between the light steel keels;
[0008] An internal support splicing assembly is disposed between the light steel keel and the rectangular frame;
[0009] A hoisting assembly, which is mounted on the rectangular frame;
[0010] The internal support splicing assembly includes several first springs, each of which is fixedly connected to the bottom surface of the rectangular frame. The lower end of each first spring is connected to a support plate, and several insertion holes are provided at both ends of the upper and lower surfaces of the light steel keel.
[0011] As a further technical solution, the upper surface of the rectangular frame and the lower surface of the support plate are provided with a number of insert blocks, all of which are inserted into the insertion holes.

[0012] As a further technical solution, the lower surface of the light steel keel is provided with a notch, the surface of the support plate is provided with a circular hole, the nut part of the support bolt is inserted into the circular hole, and a limiting layer is provided on the support bolt.
[0013] As a further technical solution, the hoisting assembly includes a connecting cavity, which is opened on the top of the rectangular frame. A docking hole is provided at the top of the connecting cavity, and a connecting frame is inserted into the connecting cavity. Several second springs are provided on the lower end face of the connecting frame.
[0014] As a further technical solution, a patch is provided at the lower end of the second spring, the patch is supported on the bottom surface of the connecting cavity, a rotating block is provided at the upper end of the connecting frame, a hanging rod is rotatably connected to the rotating block, and an expansion anchor is provided at the upper end of the hanging rod.
[0015] As a further technical solution, both ends of the top of the light steel keel are bent inward and extended, and the surface of the extended part of the top of the light steel keel is provided with several slots.
[0016] As a further technical solution, the connecting frame is T-shaped, and the shape and size of the horizontal part at the lower end of the connecting frame and the patch match the mating hole.

[0018] As a further technical solution, the rectangular frame and the support plate are matched with the internal dimensions of the light steel keel.
[0019] As a further technical solution, a pair of anti-detachment holes are provided at the top of the connecting cavity, and an anti-detachment block is provided on the bottom surface of the upper end of the connecting frame, with the anti-detachment block inserted into the anti-detachment hole.
[0020] The beneficial effects of the embodiments disclosed herein are as follows:
[0021] 1. The beneficial effect of the internal support splicing component in this disclosure is that the first spring and the support plate cooperate to flexibly adjust the position in the early stage of installation, which facilitates the insertion of the rectangular frame into the light steel keel. The design of the plug and the plug hole realizes precise positioning and preliminary splicing, ensuring the accuracy of the connection. The setting of the internal thread sleeve and the support bolt, after the preliminary installation is completed, replaces the first spring as the main support point, firmly splices the components together, greatly enhances the strength of the connection, effectively prevents the light steel keel from misaligning under stress, and improves the stability of the entire keel frame structure.
[0022] 2. The beneficial effects of the hoisting assembly in this disclosure are that the design of the connecting cavity, docking hole, and T-shaped connecting frame makes the installation of the connecting frame convenient and stable. The method of rotating 90° and offsetting it from the docking hole effectively prevents the connecting frame from falling off. The second spring and patch provide elastic support and cushioning, reducing the loosening of the connection caused by vibration or external force. The rotating block allows the hoisting rod to rotate flexibly, making it easy to adjust the angle according to the actual installation environment. The expansion anchor firmly fixes the keel frame to the support structure, ensuring the reliability of hoisting and meeting the installation needs of different building scenarios.

[0036] like Figures 1-5 As shown, it illustrates a plug-in light steel keel frame according to an embodiment of the present disclosure, comprising:
[0037] A pair of light steel keels 1 and a rectangular frame 2, with the rectangular frame 2 inserted between the light steel keels 1;
[0038] The internal support splicing component 3 is installed between the light steel keel 1 and the rectangular frame 2;
[0039] Lifting assembly 4 is mounted on rectangular frame 2;
[0040] The internal support splicing component 3 includes several first springs 3-1, each of which is fixedly connected to the bottom surface of the rectangular frame 2. The lower end of each first spring 3-1 is connected to a support plate 3-2. Several insertion holes 3-3 are provided at both ends of the upper and lower surfaces of the light steel keel 1. Several insertion blocks 3-4 are provided on the upper surface of the rectangular frame 2 and the lower surface of the support plate 3-2. The insertion blocks 3-4 are inserted into the insertion holes 3-3. An internal threaded sleeve 3-5 is provided inside the rectangular frame 2. A support bolt 3-6 is screwed into the internal threaded sleeve 3-5. A notch 3-7 is provided on the lower surface of the light steel keel 1. A circular hole 3-8 is provided on the surface of the support plate 3-2. The nut part of the support bolt 3-6 is inserted into the circular hole 3-8. A limiting layer 3-9 is provided on the support bolt 3-6.
[0041] In some examples, to achieve a secure splicing effect for the light steel keel 1, an internal support splicing component 3 is designed. This component includes multiple first springs 3-1 fixed to the bottom of a rectangular frame 2. The rectangular frame 2 is inserted between two light steel keels 1, connecting them. The elasticity of the first springs 3-1 allows the support plate 3-2 to move up and down to a certain extent when under force. After compression, the rectangular frame 2 and the support plate 3-2 are inserted into the light steel keel 1. The support plate 3-2 will adhere to the inner bottom surface of the light steel keel 1 under certain pressure due to the elasticity of the first springs 3-1. Several insertion holes 3-3 are provided at both ends of the upper and lower surfaces of the light steel keel 1. Several insertion blocks 3-4 are provided on the upper surface of the rectangular frame 2 and the lower surface of the support plate 3-2. The insertion blocks 3-4 are inserted into the insertion holes. Inside hole 3-3, the mating structure of the insert block 3-4 and the insert hole 3-3 enables the positioning and splicing between the rectangular frame 2, the support plate 3-2 and the light steel keel 1, ensuring the stability of the connection and the accuracy of the installation position. The rectangular frame 2 is provided with an internal threaded sleeve 3-5, and a support bolt 3-6 is screwed into the internal threaded sleeve 3-5. The lower surface of the light steel keel 1 is provided with a notch 3-7, and the surface of the support plate 3-2 is provided with a circular hole 3-8. The nut part of the support bolt 3-6 is inserted into the circular hole 3-8. By rotating the support bolt 3-6 and moving it downward, the limiting plate on the support bolt 3-6 will press against the surface of the support plate 3-2, replacing the support point of the first spring 3-1 with the support bolt 3-6. In this state, the support plate 3-2 can no longer move, achieving the effect of splicing and fixing.
[0042] like Figures 1-5As shown, this embodiment proposes a hoisting assembly 4 including a connecting cavity 4-1, which is located on the top of the rectangular frame 2. A mating hole 4-2 is provided at the top of the connecting cavity 4-1. A connecting frame 4-3 is inserted into the connecting cavity 4-1. Several second springs 4-4 are provided on the lower end face of the connecting frame 4-3. A patch 4-5 is provided at the lower end of the second springs 4-4. The patch 4-5 is supported on the bottom surface of the connecting cavity 4-1. A rotating block 4-6 is provided on the upper end of the connecting frame 4-3. A lifting rod 4-7 is rotatably connected to the rotating block 4-6. An expansion anchor 4-8 is provided on the upper end of the lifting rod 4-7.
[0043] In some examples, a lifting assembly 4 is designed to achieve the lifting connection effect. This assembly includes a connecting cavity 4-1 located inside a rectangular frame 2. The connecting cavity 4-1 has a cylindrical structure with a mating hole 4-2 at its top. A connecting bracket 4-3 is inserted into the connecting cavity 4-1. During insertion, the bracket 4-3 passes through the mating hole 4-2 before entering the connecting cavity 4-1. After insertion, the connecting bracket 4-3 rotates 90° to offset its position from the mating hole 4-2, making it impossible to remove. The lower end face of the connecting bracket 4-3 has several second... Spring 4-4, the lower end of the second spring 4-4 is connected to a patch 4-5, the patch 4-5 is supported on the bottom surface of the connecting cavity 4-1. The second spring 4-4 uses its elasticity to form a supporting force between the patch 4-5 and the connecting frame 4-3 and support it in the connecting cavity 4-1. A rotating block 4-6 is set at the upper end of the connecting frame 4-3. A hanger 4-7 is rotatably connected to the rotating block 4-6, so that the hanger 4-7 can rotate during installation. The top of the hanger 4-7 is equipped with an expansion anchor 4-8, which can be tightly embedded into the wall to form a fixed structure through its expansion.
[0044] For example, such as Figure 1 As shown, both ends of the top of the light steel keel 1 are bent inward and extended, and several slots 5 are opened on the surface of the extended part of the top of the light steel keel 1.
[0045] In some examples, the strength of the top of the light steel keel 1 can be increased by bending it inward, and the splicing can be completed in conjunction with the structure. The bayonet 5 is provided to facilitate connection with other lifting components.
[0046] For example, such as Figure 5 As shown, the connector 4-3 has an overall T-shaped structure. The shape and size of the horizontal part at the lower end of the connector 4-3 and the patch 4-5 match the mating hole 4-2.
[0047] In some examples, the T-shaped structure allows the connecting bracket 4-3 to be rotated 90° to completely offset the position of the mating hole 4-2, making it easier to fix during installation.
[0048] For example, such as Figure 3As shown, the rectangular frame 2 has a hollow interior, and the internal threaded sleeve 3-5 is located in the center of the rectangular frame 2.
[0049] In some examples, the overall weight of the rectangular frame 2 is reduced by using a hollow structure, and the internal threaded sleeves 3-5 are used to ensure support strength.
[0050] For example, such as Figure 3 As shown, the rectangular frame 2 and the support plate 3-2 are matched with the internal dimensions of the light steel keel 1.
[0051] In some examples, by matching the dimensions, the rectangular frame 2 and the support plate 3-2 can form an internal bracing effect to resist deformation after insertion.
[0052] For example, such as Figure 5 As shown, a pair of anti-detachment holes 6 are provided at the top of the connecting cavity 4-1, and an anti-detachment block 7 is provided on the bottom surface of the upper end of the connecting frame 4-3. The anti-detachment block 7 is inserted into the anti-detachment hole 6.
[0053] In some examples, the connecting frame 4-3 and the rectangular frame 2 can be further fixed by the anti-detachment hole 6 and the anti-detachment block 7, which provides a better limiting effect for the connecting frame 4-3.
[0054] In actual use: Press the support plate 3-2 to retract the first spring 3-1, then insert the rectangular frame 2 and the support plate 3-2 between a pair of light steel keels 1. After releasing, the elastic force of the first spring 3-1 causes the insert block 3-4 to be inserted into the insertion hole 3-3. Rotate the support bolt 3-6 and insert its nut into the circular hole 3-8 of the support plate 3-2. Use the limiting layer 3-9 to push the support plate 3-2 downward to form a fixation. Fix the hanger 4-7 to the ceiling or other support structure through the expansion anchor bolt 4-8. Insert the connecting frame 4-3 into the docking hole 4-2 and into the connecting cavity 4-1. Then rotate it 90° to make it offset from the docking hole 4-2. The second spring 4-4 and the patch 4-5 provide support. Insert the anti-detachment block 7 into the anti-detachment hole 6 to complete the fixation. The hanger 4-7 rotates with the connecting frame 4-3 through the rotating block 4-6, which can be used to install the expansion anchor bolt 4-8.
