[0025] The steel member 1 is fixedly connected with a leakage-proof sealing strip 22 on the two sides and outside the inserting plate 2; by arranging the leakage-proof sealing strip 22, the contact between the steel member 1 and the wood mold plate 3 is more close, and the possibility of slurry leakage is prevented.
[0026] The steel member 1 is provided with a rib 23 at the inside corner, for reinforcing the steel member 1 at the inside corner.
[0027] Working principle: During on-site construction, steel component 1 is customized according to the thickness of the formwork used, and pre-embedded reinforcing bars 14 are pre-embedded during the construction of the bottom and top slabs. When erecting the formwork, steel component 1 is erected first and tightened using inclined support steel pipes 6. Then, through the installation of insertion plates 2 and insertion slots 4, the steel component 1 and the wooden formwork 3 can be spliced. Through the cooperation of screws 8, fixing plates 9, nuts 10, connecting plates 11, clamping plates 12, clamping slots 13, and the fixing mechanism, screws 8 can be inserted between the wooden formwork 3 and the steel component 1 and the transverse support steel pipes 5, and clamping plates 12 on the fixing plate 9 can be inserted into the clamping slots 13 on the connecting plate 11. At this time, one end of the limiting rod 19 is connected to the clamping plate 12. The inclined surfaces of the two parts come into contact, causing the limiting rod 19 to move the movable plate 16 within the cavity 15. At this time, the spring 21 on the movable rod 17 contracts and undergoes elastic deformation. When the limiting rod 19 is aligned with the limiting hole 20, the spring 21 returns to its elastic deformation, allowing the limiting rod 19 to insert into the limiting hole 20, thus completing the fixation of the fixing plate 9. Subsequently, tightening the nut 10 facilitates the connection and reinforcement between the steel component 1, the wooden formwork 3, the transverse support steel pipe 5, and the timber 7. The operation is simple, and the transverse support steel pipe 5 is reinforced with fasteners at the external corners. The anti-leakage sealing strip 22 ensures a tighter contact between the steel component 1 and the wooden formwork 3, preventing possible grout leakage. During concrete pouring, the internal and external corners should be fully vibrated to prevent quality problems caused by insufficient vibration. The steel component 1 in this utility model is made of alloy steel, which can increase the load-bearing capacity of the wooden formwork 3 system and prevent collapse accidents.
