Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a template top supporting device. Background Art

[0002] Building formwork is a temporary support structure, which is made according to the design requirements to shape the concrete structure and components according to the specified position and geometric size, maintain its correct position, and bear the deadweight of the building formwork and the external loads acting on it. The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up the construction progress and reduce engineering costs.

[0003] In the process of pouring concrete floor slabs, it is usually necessary to use a formwork as a base plate to support the weight of the concrete, so as to limit the flowing concrete to a certain area, and then remove the formwork after the concrete solidifies; scaffolding is usually used as a supporting structure for the formwork, but in the process of supporting the formwork, it is difficult to adjust the length of the steel pipes that constitute the scaffolding, thereby making it difficult to adjust the supporting height of the formwork during the process of using the scaffolding to support the formwork.

[0004] The utility model with patent number CN218292808U discloses a template top support device, including a support seat and an adjustment plate. Six card slots are opened on one side of the adjustment plate. A fixing mechanism matched with the card slots is provided on one side of the support seat. A No. 2 screw rod is rotatably connected to the top of the adjustment plate. An adjustment block is threadedly connected to the outer side of the No. 2 screw rod. Two limit plates are symmetrically slidably connected inside the adjustment block. The limit plate is fixedly connected to the adjustment plate. A support box is fixedly connected to the top of the adjustment block. Two No. 1 support plates are symmetrically slidably connected inside the support box. A No. 2 support plate is fixedly connected to the top of the No. 1 support plate. The No. 2 support plate is slidably connected to the support box. An adjustment mechanism is provided inside the support box. The No. 1 support plate is connected to the adjustment mechanism. When in use, the adjusting bolt is rotated, and the adjusting bolt drives the card block to leave the fixed card slot to adjust the height position of the adjustment plate. Then, the adjusting bolt is rotated to drive the card block to fix the adjustment plate with the card slot at a suitable height position. The worm is rotated by the No. 2 rotating block. The worm drives the No. 2 screw rod to rotate through the worm gear. The No. 2 screw rod adjusts the height position of the adjustment block. In this patent, the height of the No. 1 support plate and the No. 2 support plate can be roughly adjusted by connecting the fixing mechanism with the card slots of different heights, and the height of the No. 1 support plate and the No. 2 support plate can be finely adjusted by the No. 2 screw rod, so that templates of different heights can be supported. However, in the process of roughly adjusting the height of the No. 1 support plate and the No. 2 support plate, it is necessary to first separate the card block from the card slot by adjusting the bolt, and then move up or down the height of the adjustment plate. During the operation, one person is required to operate the separation and connection of the card block and the card slot, and the other person is required to move up or down. The adjustment plate requires two operators to work closely together, and it is difficult for one person to adjust the height of the entire formwork support device. At the same time, after the height of the adjustment plate is adjusted into place, when the card block is connected with the card slot, it is necessary to fine-tune the height of the adjustment plate so that the card slot and the card block are opposite, so that the card block can be inserted into the card slot to fix the position of the adjustment plate. This requires the staff responsible for moving the adjustment plate to slowly move up or down the adjustment plate, as well as the limit plate, turbine, worm gear, No. 1 support plate, No. 2 support plate, etc. connected to the adjustment plate. Due to the weight of each component, the operation is inconvenient. Utility Model Content
