Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a formwork-free structural column structure. Background Technology

[0002] In building construction, the secondary structural concrete columns involve a large volume of work and largely determine their quality. The installation and removal of formwork for concrete components is often cumbersome, extending the construction period. To improve efficiency, existing technologies use specialized U-shaped hollow blocks for formwork-free construction of structural columns. This involves first tying the structural column reinforcement, then constructing the hollow blocks simultaneously with the wall blocks. Each wall section is poured after reaching a designated height. While this method improves efficiency and simplifies the process, it also presents challenges in practice: the blocks are aligned sequentially with concrete, resulting in a small contact area and potential for structural instability. Furthermore, relative displacement is common, and the lack of effective installation and positioning structures often affects the construction quality of the structural columns.

[0003] Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0004] The purpose of this invention is to provide a method that can both improve construction efficiency and effectively ensure...

[0005] Formwork-free column construction for secondary structural columns.

[0006] The technical solution adopted by this utility model to solve its technical problem is: to provide a formwork-free structural column structure, including a first U-shaped block and a second U-shaped block placed outside the structural column steel bars and with the opening facing the horizontal direction. The first U-shaped block and the second U-shaped block are arranged in a cyclic manner from bottom to top and cooperate with the toothed wall structure on both sides.

[0007] A connecting component is provided between the first U-shaped block and the second U-shaped block, and a fixing component is provided between the first U-shaped block and the vertical reinforcement of the structural column.

[0008] The connecting component includes rectangular mating grooves at the center of the parallel portions on both the upper and lower sides of the first U-shaped block, and rectangular mating blocks that mate with the mating grooves at the center of the parallel portions on both the upper and lower sides of the second U-shaped block. The two corners of the mating blocks on the side away from the second U-shaped block are rounded.

[0009] The inner wall of the docking groove is symmetrically provided with docking holes on both sides. Each docking hole is horizontally slidably connected with a plug rod. The outer end of the plug rod is arc-shaped. A spring is fixedly connected between the inner end of the plug rod and the inner wall of the docking hole. The outer walls of both sides of the docking block are provided with plug holes that cooperate with the ends of the plug rods.

[0010] The fixing component includes a mounting groove laterally opened at the center of the opposite side of the opening of the first U-shaped block. A bidirectional lead screw is rotatably connected between the two sides of the mounting groove. Sliding blocks are symmetrically arranged on both sides of the bidirectional lead screw and slidably connected to the inner side of the mounting groove. A fixing hook is fixedly connected to the inner outer wall of each sliding block. The fixing hook is engaged with the vertical rib.

[0011] The center of the bidirectional lead screw is coaxially sleeved with a worm gear, which meshes with a worm. The bottom end of the worm is rotatably connected to the bottom of the mounting groove. The top of the first U-shaped block has a groove corresponding to the worm. The top of the worm passes through to the bottom of the groove and is rotatably connected to the inside of the first U-shaped block.

[0012] The bottom of the worm gear is fixedly connected to a first turntable, and the outer side of the first turntable is provided with a first groove that mates with a Phillips screwdriver.

[0013] A metal positioning plate is provided at the bottom of the groove around the outside of the worm, and the metal positioning plate is welded to the worm.

[0014] A U-shaped frame is fixedly connected to the inner wall of the sliding block, a sliding plate is slidably connected to the inner side of the U-shaped frame, a connecting rod is fixedly connected to the front side of the sliding plate and is disposed on the outside of the U-shaped frame and slidably engaged with the U-shaped frame, and the fixing hook is fixedly connected to the outer end of the connecting rod.

[0015] A threaded rod is fixedly connected to the rear side of the sliding plate, and the thread passes through the sliding plate.

[0016] The outer side of the moving block is threadedly connected to the sliding block, and the outer end of the threaded rod is fixedly connected to a second turntable. The outer side wall of the second turntable is provided with a second rotating groove that mates with a Phillips screwdriver. When the fixing hook is fixedly connected to the vertical rib, the outer side of the second turntable is located inside the mounting groove.

[0017] The threaded rod and the sliding block are made of metal and are welded together.

[0018] In practical use, the following steps are taken: First, the first U-shaped block is fixed to the outside of the structural steel column. The bottom of the first U-shaped block, located at the bottommost side, does not require a butt groove. Then, the second U-shaped block is joined to the first U-shaped block with the openings facing the same direction. During the insertion of the butt block into the butt groove, the insert rod is pressed into the inside of the butt hole. When the bottom of the butt block contacts the bottom of the butt groove, the insertion hole corresponds precisely to the position of the insert rod. The end of the insert rod is inserted into the insertion hole, effectively connecting the first and second U-shaped blocks and fixing their relative positions. Then, the fixing components are operated. By rotating the second turntable with a screwdriver, the threaded rod rotates, pushing the sliding plate to extend the fixing hook forward to the front of the adjacent vertical reinforcement. Then, by rotating the first turntable with a screwdriver... The turntable drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the double-sided screw to rotate, thereby moving the two sliding blocks to align the two fixed hooks with the vertical reinforcement. The second turntable is then adjusted to retract the fixed hooks and stably attach them to the vertical reinforcement. The threaded rod is spot-welded to the outer contact part of the sliding block, and the first turntable is spot-welded to the metal positioning plate to fix the connection structure between the column fixed hooks and the vertical reinforcement. Construction proceeds sequentially upwards, with the opening direction changing left and right, so that the first U-shaped block is connected and fixed to the structural column reinforcement from both sides, increasing the overall stability. The top of the second U-shaped block at the very top does not have a butt joint but has a grouting port. The lower part is grouted in stages during construction, for example, grouting is done once when three U-shaped blocks are connected.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model can increase the connection stability of the upper and lower U-shaped blocks through the connecting components, thereby improving the construction quality of the structural column;

[0021] 2. This utility model uses a fixing component to connect and fix the U-shaped block to the structural column reinforcement from both sides, which further improves the stability and standardization of the overall structure, and ensures the construction quality of the structural column while improving construction efficiency.
