Description

Technical Field

[0001] This utility model relates to the field of building engineering, and more specifically, to a high-strength support device for precast floor slabs in building construction. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities. In order to facilitate installation and construction, support columns are needed for auxiliary reinforcement.

[0003] The utility model patent with authorization announcement number CN221567940U relates to the field of building engineering technology and discloses a multifunctional support device for building engineering, including a support column. The top of the support column is threaded with mounting bolts around its perimeter, and a centering plate is fixedly connected to its bottom perimeter. A sliding component is installed at the bottom of the support column. Through the arrangement of a support base, side plates, pulleys, positioning bolts, adjusting handwheels, limiting plates, limiting holes, and slide rails, the pulleys are installed inside the limiting plates. The slide rails facilitate the pulleys' movement along the inner wall of the limiting plates, allowing the support base and support column to slide during movement. Turning the adjusting handwheel causes the positioning bolts to extend and retract, inserting one end of the positioning bolt into the inner wall of the limiting hole to position the support base. After the support components of the building engineering are fixedly installed, the position of the device can be adjusted, avoiding manual disassembly and reassembly, saving time and effort, and achieving optimal performance.

[0004] In the above-disclosed structure, the limiting mechanism is connected by a support column. However, the side connection and positioning can easily cause interference, affecting the convenience and accuracy of sliding adjustment and alignment. In addition, the lack of a pad to adjust the gap results in insufficient stability. Furthermore, it cannot be locked with the assistance of locking screws, and the height cannot be adjusted for alignment. These issues need to be addressed. Summary of the Invention

[0026] Please see Figure 1 , Figure 3 and Figure 4 A high-strength support device for precast floor slabs in building construction includes a fixed base 1. The fixed base 1 has a combination groove 11 inside, with an opening groove 12 on one side. Positioning holes 13 are provided on both sides of the opening groove 12. A positioning block 14 is slidably installed inside the combination groove 11, allowing it to be slidably installed into the combination groove 11 and thus connected to the fixed base 1. This allows for positioning onto the building frame, facilitating construction. Alignment holes 15 are provided on both sides of the positioning block 14, with positioning screws 16 threaded inside the alignment holes 15. One end of the positioning screw 16 is rotatably installed inside the positioning hole 13. Installing the positioning screw 16 from the top position allows for fixed installation without obstructing the view, and it can be pulled out for adjustment of the positioning block 14's position, avoiding interference and providing convenience and efficiency. A support column 17 is fixedly welded to the upper surface of the positioning block 14. The device has an internal adjusting threaded hole 18, and an adjusting threaded rod 2 is installed inside the adjusting threaded hole 18. One end of the adjusting threaded rod 2 is fixedly connected to a support plate 21. The height is adjusted by adjusting the thread of the adjusting threaded rod 2, thereby aligning the support plate 21 onto the building frame. This facilitates positioning and installation, providing high adaptability and safety. The surface of the support plate 21 has mounting holes 22. The support plate 21 is located at the upper end of the support column 17. A pad 25 is connected to the upper surface of the positioning block 14. One side of the pad 25 has a snap-fit ​​groove 26, which snaps into the outer surface of the support column 17. The pad 25 is tightly connected to the inner side of the combination groove 11. During connection, the snap-fit ​​groove 26 can be snapped onto the support column 17, thereby connecting to the positioning block 14. This provides auxiliary support for the positioning block, eliminating the gap with the combination groove 11, ensuring the stability of the positioning screw 16, preventing loosening, and facilitating combined use.

[0027] Please see Figure 1 and Figure 2 Both ends of the fixed base 1 are connected with bottom bolts 27. The bottom bolts 27 are symmetrically distributed at both ends of the inner part of the combination groove 11. The lower surface of the positioning block 14 is provided with a clearance groove 28. The clearance groove 28 is sleeved on the outer surface of the bottom bolt 27. By connecting the bottom plate bolts and combining the clearance groove, the fixed base can be connected and fixed without interfering with the combination installation of the positioning block. It has high adaptability and is easy to adjust and use. The clearance groove 28 can avoid the bottom bolt 27 without interference, making it easy for the positioning block 14 to slide into the combination groove 11 and then adjust its position for fixing. The bottom bolt 27 can first fix the fixed base 1 to the support position, which is conducive to supporting and reinforcing the building components.

[0028] Please see Figure 2 and Figure 5 The upper end of the support column 17 is provided with a countersunk hole 23. A locking screw 24 is threaded onto one side of the countersunk hole 23. A rotating head 3 is rotatably mounted on one end of the locking screw 24. The rotating head 3 is located inside the countersunk hole 23. A semi-circular ring 31 is fixedly connected to one end of the rotating head 3. The semi-circular ring 31 is slidably connected inside the countersunk hole 23. A locking thread 32 is provided on the inner surface of the semi-circular ring 31. The locking thread 32 is tightly connected to the outer surface of the adjusting thread rod 2. The semi-circular ring is installed by the locking screw, and the locking thread can be used to tighten the screw. The thread adjustment is tightened and reinforced without damaging the threads of the adjusting thread rod. It facilitates clamping and limiting, prevents loosening, improves safety, and is convenient and stable. After the adjusting thread rod 2 is positioned, the locking screw 24 can be rotated to push the semi-circular ring 31 to slide inside the countersunk hole 23. It can be pressed against the surface of the adjusting thread rod 2, and then the locking thread 32 engages with the thread surface of the adjusting thread rod 2. This can help limit the movement, prevent loosening, and prevent the threads from being squeezed and damaged, thus improving safety and stability and facilitating combined use.
