When removing the formwork, the originally designed floor is put in a short span (short span less than 2m) stress state, that is, the span of the floor formwork is kept within the span requirements specified in relevant specifications. In this way, the floor formwork and part of the support can be removed as long as the concrete strength reaches 50% of the design strength, while the columns, columns and adjustable supports remain in a supporting state.
[0003] Early dismantling formwork technology can be applied to the construction of floor slabs and beams of various types of public buildings, residential buildings, floor slabs and beams of frame structure buildings, and structural top plate formwork of municipal engineering projects such as bridges and culverts. In the process of connecting the early dismantling head with the aluminum formwork side frame, pin docking or bolt connection is generally adopted. However, relying on pins or bolts as connecting parts requires a greater supporting force, and pins and bolts are prone to loosening or even falling off when subjected to vibration. For this reason, it is necessary to provide an aluminum formwork early dismantling node structure, which adopts a high-strength and large-bearing-surface docking card for connection to improve the supporting strength, and at the same time cooperates with an anti-drop bolt structure to prevent rotation due to vibration, thereby preventing loosening and falling off.

At the same time, the stud 12 and the supporting leg 11 are used in coordination to support the supporting screw 2. The support height can be adjusted, so that the support height of the early removal head 1 to the aluminum mold side frame 3 and the aluminum film plate 4 can be adjusted. The front and rear sides of the aluminum mold side frame 3 are provided with aluminum film plates 4, and the front and rear sides of the early removal head 1 are provided with docking card plates 5. The front and rear sides of the early removal head 1 are provided with limited card grooves 6. A docking card shell 7 is welded on the side of the bottom of the aluminum mold side frame 3 close to the early removal head 1.
