Description

Technical Field

[0001] This utility model relates to the field of steel support beam technology, specifically a prefabricated building support beam component. Background Technology

[0002] Steel structures are one of the main types of building structures, primarily composed of prefabricated components such as steel beams, steel columns, and steel trusses. They undergo rust removal and prevention processes including silanization, pure manganese phosphating, water washing and drying, and galvanizing. Due to their light weight and ease of construction, they are widely used in large factories, stadiums, and high-rise buildings. During the installation of prefabricated steel support beams, vertical and horizontal steel beams are typically connected using prefabricated base components. To secure these three components, multiple bolts or welding are generally used. However, connecting the vertical and horizontal steel beams to the base with multiple bolts requires multiple nuts. While this method enhances the connection between the vertical and horizontal steel beams and the base, it is cumbersome due to the need to operate multiple nuts. Furthermore, while welding ensures a good connection, it hinders disassembly. Therefore, we propose a prefabricated building support beam to address these issues. Utility Model Content

A fixing block adapted to the fixing slot II is slidably passed through the top of each limiting seat, and each fixing block is inserted into the corresponding fixing slot II. A spring is fixed to the top of each limiting seat, and the top of each spring is fixedly connected to the corresponding fixing block. A transmission assembly is provided on the base to simultaneously drive the four card plates and four fixing blocks to move.

[0008] Furthermore, the transmission assembly includes a lead screw rotatably connected to the base via a bearing, a movable plate threaded onto the surface of the lead screw, the movable plate sliding inside the base, and four connecting rods rotatably connected to the outer wall of the movable plate via pins.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an embodiment of this utility model discloses a prefabricated building support beam, including a base 1, a support seat 2 fixed to the top of the base 1, a vertical support beam 3 inserted into the top of the support seat 2, four fixing grooves 4 on the outer wall of the vertical support beam 3, and four through-holes on the outer wall of the support seat 2, each having a slidably connected card plate 5 adapted to the fixing groove 4, one end of each card plate 5 being inserted into the corresponding fixing groove 4. Four limiting seats 6 are fixed to the outer wall of the base 1, and two reinforcing plates 1 are fixed to the bottom of each limiting seat 6. 2. One side wall of the reinforcing plate 12 is fixedly connected to the base 1, which can provide auxiliary support for the limiting seat 6, making it more sturdy after being fixed to the base 1. A horizontal support beam 7 is inserted into the inside of each limiting seat 6. Two fixing slots 8 are opened on the top of each horizontal support beam 7. Fixing blocks 9 that are compatible with the fixing slots 8 slide through the top of the limiting seat 6. The fixing blocks 9 are respectively inserted into the corresponding fixing slots 8. A spring 10 is fixed to the top of each limiting seat 6, and the top of the spring 10 is respectively connected to the corresponding fixing block 9. A fixed connection is provided. The base 1 is equipped with a transmission assembly 11 that simultaneously drives four clamping plates 5 and four fixing blocks 9 to move. During the fabrication of this support beam prefabrication component, the vertical support beam 3 can be installed on the support base 2, followed by the installation of the four horizontal support beams 7 on the limiting seats 6. Then, the transmission assembly 11 is operated. When the transmission assembly 11 moves, it drives the clamping plates 5 to move. After the clamping plates 5 move, one end of each plate will be inserted into the fixing groove 4, thus completing the limiting and fixing of the vertical support beam 3. Furthermore, when the transmission assembly 11... When moving, the four fixed blocks 9 can be pushed to move. When the fixed blocks 9 move down, their bottom ends will be inserted into the fixed grooves 8 opened in the corresponding horizontal support beams 7. At this time, the horizontal support beams 7 can be limited and fixed. When disassembling, the transmission component 11 can be operated again. When the card plate 5 and the fixed blocks 9 release the restriction on the vertical support beams 3 and the horizontal support beams 7, the two can be separated from the base 1. The spring 10 is set so that it can automatically reset after the transmission component 11 releases the restriction on the fixed blocks 9.

[0024] like Figure 1 and Figure 2As shown, in some embodiments, the transmission assembly 11 includes a lead screw 1101 rotatably connected to the base 1 via bearings. A hexagonal rotating block 1107 is fixed to the top of the lead screw 1101. A hexagonal groove 1108 is provided on the top of the hexagonal rotating block 1107, which facilitates the use of different tools to drive the lead screw 1101 to rotate. A movable plate 1102 is threadedly connected to the surface of the lead screw 1101. The movable plate 1102 slides inside the base 1. Four connecting rods 1103 are rotatably connected to the outer wall of the movable plate 1102 via pins. The other end of each connecting rod 1103 is rotatably connected to a pressing block 1104 adapted to the fixed block 9 via pins. The fixed block 9 is respectively connected to the opposite... The corresponding pressing blocks 1104 are attached, and the bottom of the clamping plate 5 is fixedly connected to the corresponding pressing blocks 1104. In use, by rotating the screw 1101, the screw 1101 can drive the moving plate 1102 to move upward. After the moving plate 1102 moves upward, it can simultaneously drive the four pressing blocks 1104 to move towards the middle position with the cooperation of the four connecting rods 1103. After the pressing blocks 1104 move, they can drive the clamping plate 5 to move towards the middle. Therefore, the vertical support beam 3 can be limited and fixed. When the pressing blocks 1104 move, they can press the fixing block 9. After being pressed, the fixing block 9 will move down and insert into the inside of the fixing groove 8. Therefore, the horizontal support beam 7 can be limited and fixed.

[0025] like Figure 2 As shown, in some embodiments, four U-shaped guide rails 1105 are fixed on the outer wall of the base 1, and sliders 1106 adapted to the U-shaped guide rails 1105 are fixed on both sides of the extrusion block 1104, which can play an auxiliary supporting and guiding role for the extrusion block 1104, and at the same time make it more stable during movement.

[0026] like Figure 1 As shown, in some embodiments, the outer wall of the support base 2 is provided with a clearance groove 1109 to facilitate the rotation of the lead screw 1101, which serves to allow the operator to use tools to rotate the lead screw 1101.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
