[0002] Column hoops are essential tools for fixing column formwork during the construction of reinforced concrete columns. They are horizontal supports that connect the column formwork to the vertical ribs to form a whole. In order to avoid problems such as bulging, swelling, and slippage of the column formwork, we have designed a variable cross-section column hoop adjuster for building construction. It can be folded and stored to reduce the space occupied, and it can also be adjusted according to the size of the column cross-section, making it highly adaptable. Utility Model Content

Movable square steel is fitted onto the surfaces of the two side square tubes. A fastening assembly is provided between the side square tubes and the square steel. The fastening assembly includes a square hole in the square steel for the side square tubes to pass through. A T-slot is provided on the side square tube. Nuts are fixedly connected to both sides of the square steel. A screw is threaded into the inner cavity of the nut. One end of the screw extends into the inner cavity of the T-slot and is fixedly installed with an extrusion plate. Side extrusion rods are rotatably connected to the opposite sides of the two side square tubes via a rotating shaft. A pushing assembly is provided between the side extrusion rods and the side square tubes.

[0005] Preferably, the two side square tubes are arranged in an alternating vertical arrangement.

[0006] Preferably, the propulsion assembly includes a rotating block rotatably connected to the inside of the side extrusion rod via a rotating shaft, a short threaded column rotatably connected to one side of the rotating block, a threaded sleeve rotatably connected to the top of the side square tube, and the short threaded column threadedly connected to the inner cavity of the threaded sleeve.

[0007] Preferably, one end of the short threaded post is rotatably connected to a long threaded post via a rotating shaft, and the long threaded post is adapted to the threaded sleeve.

[0008] Preferably, an operating rod is fixedly installed at the end of the long threaded column.

[0009] The beneficial effects of this utility model are:

[0010] This invention involves unfolding the side square tubes to a 90-degree angle with the main square steel and fitting them onto the outside of the column template. Then, the square steel is fitted onto the surface of the two side square tubes, ensuring that the square steel and the main square steel are in contact with the column template beforehand. The fastening components are then used to lock the square steel in place. Finally, the pushing components are used to press the side extrusion rods against the column template, achieving four-way support and effectively preventing bulging, swelling, and slippage of the template. This design allows for folding and storage, reducing space occupation, and can be adjusted according to the size of the column cross-section, resulting in high adaptability.

[0017] In the following description, embodiments of the anti-expansion mold variable cross-section column hoop adjuster of this utility model for building engineering will be described with reference to the accompanying drawings.

[0018] Figure 1-5This invention illustrates an embodiment of a variable cross-section column hoop adjuster for anti-expansion formwork in building engineering. It includes a main square steel 1, with two lateral square tube fittings 2 rotatably connected to its front ends via pivots. The two lateral square tube fittings 2 are arranged in an alternating vertical configuration. Movable square steel 3 is fitted onto the surface of each lateral square tube fitting 2. A fastening assembly 4 is provided between the lateral square tube fittings 2 and the square steel 3. The fastening assembly 4 includes a square hole 41 in the square steel 3 for the lateral square tube fittings 2 to pass through. A T-slot 42 is provided on the lateral square tube fittings 2. Nuts 43 are fixedly connected to both sides of the square steel 3. Screws 44 are threaded into the inner cavity of the nuts 43, with one end of the screws 44 extending into the T-slots. An extrusion plate 45 is fixedly installed in the inner cavity of 42. The two side square tubes 2 are rotatably connected to the side extrusion rods 5 via a rotating shaft on opposite sides. A propulsion assembly 6 is provided between the side extrusion rods 5 and the side square tubes 2. The propulsion assembly 6 includes a rotating block 61 rotatably connected to the inner side of the side extrusion rods 5 via a rotating shaft. A short threaded column 62 is rotatably connected to one side of the rotating block 61. A threaded sleeve 63 is rotatably connected to the top of the side square tubes 2. The short threaded column 62 is threadedly connected to the inner cavity of the threaded sleeve 63. A long threaded column 64 is rotatably connected to one end of the short threaded column 62 via a rotating shaft. The long threaded column 64 is adapted to the threaded sleeve 63. An operating rod 65 is fixedly installed at the end of the long threaded column 64.

[0019] Working principle: In use, this utility model involves unfolding the side square tube 2 to a 90-degree angle with the main square steel 1 and fitting it onto the outside of the column template. Then, the square steel 3 is fitted onto the surfaces of the two side square tubes 2, causing the square steel 3 to adhere to the main square steel 1 on the column template. Rotating the screw 44 causes the nut 43 to move and rotate outwards, which in turn moves the extrusion plate 45 within the T-groove 42, causing the extrusion plate 45 to press against the inner wall of the T-groove 42, thus locking the square steel 3 in place. Finally, rotating the long threaded column 64 causes the long threaded column 64 to... A rod is formed with the short threaded column 62. Then, the operating rod 65 is operated to make the long threaded column 64 and the short threaded column 62 rotate. The long threaded column 64 and the short threaded column 62 will move and rotate due to the threaded sleeve 63. The short threaded column 62 will push the side extrusion rod 5 to rotate, so that the side extrusion rod 5 abuts against the cylindrical template, achieving four-way support and effectively preventing phenomena such as mold bulging, mold expansion, and mold running. During the rotation of the side extrusion rod 5, the threaded sleeve 63 will rotate at the top of the side square tube 2, ensuring that the long threaded column 64 and the short threaded column 62 can push the side extrusion rod 5 to move.

[0020] In summary, the anti-bulging formwork variable cross-section column clamp adjuster used in this construction project works by unfolding the side square tube 2 to a 90-degree angle with the main square steel 1 and fitting it onto the outside of the column formwork. Then, the square steel 3 is fitted onto the surface of the two side square tubes 2, ensuring that the square steel 3 and the main square steel 1 are in contact with the column formwork beforehand. The fastening component 4 is used to lock the square steel 3 in place, and then the pushing component 6 is used to make the side extrusion rod 5 press against the column formwork, achieving four-way support. This effectively prevents bulging, expansion, and slippage of the formwork. It can be folded and stored to reduce space occupation, and can also be adjusted according to the size of the column cross-section, achieving high adaptability.
