Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete pouring formwork technology, and specifically relates to a standardized steel formwork structure. Background Technology
[0002] Prefabricated steel formwork is a type of formwork used for concrete pouring. Compared to wooden formwork, it has advantages such as high strength, good toughness, and a high number of reuses. Therefore, steel formwork is used for pouring concrete for structural forms such as beams and columns during building construction.
[0003] Chinese patent CN220685808U discloses a steel formwork reinforcement structure for bridge pier casting. By setting up snap-fit components, it enhances the connection between the external reinforcement plate and the base. Fixed slots and limiting protrusions are used to snap the external reinforcement plates together, forming a closed structure and preventing grout leakage during casting. However, in this design, only one pier can be cast at a time. The formwork cannot be used again until one pier is demolded, resulting in a long concrete casting construction cycle.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows: a fixed steel formwork structure, including a steel formwork box and a cover plate disposed on one side of the steel formwork box. The cover plate is connected to the steel formwork box via a rotating connection structure. A pouring port is provided on the cover plate, and a pouring hopper is provided at the pouring port. The steel formwork box contains an inner formwork, which is a topless cubic structure. A cross-shaped cross plate is provided inside the inner formwork, dividing the inner formwork into four pouring areas. The position of the pouring port is adapted to the pouring area. A rotating component is provided at the bottom of the inner formwork, which drives the inner formwork to rotate so that the second pouring area is automatically poured after the first pouring area is completed.
[0006] The aforementioned rotating connection structure includes a side plate, a first guide rail, a support member, a connecting column, a first through hole, and a sealing head;
[0007] The two side plates are respectively disposed on both sides of the back of the steel formwork box, and the side plates are provided with a first guide rail and a first through hole;

[0012] The aforementioned lifting assembly includes a sliding bottom plate and a top plate arranged in parallel, with the sliding bottom plate located at the bottom of the steel formwork box.
[0013] Two sets of cross arms are provided between the sliding base plate and the top plate. Each cross arm is formed by two support rods hinged together to form an X shape. One end of each set of cross arms on the same side is hinged to the sliding base plate and the top plate respectively. Rollers are provided at the other end of each set of cross arms on the other side. A crossbar is provided between the two sets of cross arms.
[0014] A cylinder is hinged to the sliding base plate, and the power end of the cylinder is hinged to the crossbar.
[0015] As mentioned above, the upper surface of the sliding base plate and the bottom surface of the top plate are both provided with second guide rails, and the rollers are matched and connected to the second guide rails.
[0016] As described above, the center of the top plate is a hollow installation area, and an installation plate is provided in the installation area. The installation plate is fixedly connected to the top plate, and a second through hole is provided in the center of the installation plate.
[0017] The aforementioned rotating assembly includes a motor mounted on a mounting plate and a bearing disposed within a second through hole. A drive shaft is mounted within the bearing, and a first gear is disposed on the top of the drive shaft. The first gear is located on the upper surface of the top plate.

[0019] This utility model features a rotating assembly inside the steel formwork box, with an inner formwork on the rotating assembly for concrete pouring. The inner formwork is divided into four pouring areas by a cross plate. After one pouring area is completed, the rotating assembly drives the inner formwork to rotate 90°, allowing the pouring port to be aligned with the second pouring area for pouring. This allows for the pouring of four columns at once, improving pouring efficiency.
[0020] When the cover of this utility model is opened, the two ends of the crossbar slide in the first guide rail, while the connecting column rotates in the first through hole. After it is fully opened, the support overlaps on the side plate, and the two ends of the crossbar abut against the top of the first guide rail, ensuring the stability of the cover opening.
[0021] This invention also includes a lifting component at the bottom of the rotating assembly. During demolding, the cross arm can be raised by a cylinder, thereby raising the top of the inner template to the outside of the steel template box, making it easier to remove the inner template and improving demolding efficiency.
