[0005] Furthermore, some of the locks are frustum-shaped rubber columns, the end of the lock with a larger diameter is fixed to the sealing strip, and the aluminum alloy template is provided with a plurality of circular holes corresponding to the positions of the locks, and the diameter of the circular holes is smaller than the maximum diameter of the lock.
[0006] Furthermore, the sealing strip is a rubber strip, and the sealing strip is integrally formed with the lock buckle.
[0007] Furthermore, the lock buckle is 50 mm high, the diameter of the end face where the lock buckle is connected to the sealing strip is 13 mm, the diameter of the end face of the lock buckle away from the sealing strip is 7 mm, and the diameter of the circular hole on the aluminum alloy template is 10 mm.
[0008] Furthermore, the spacing between the centers of the plurality of lock buckles is 100 mm.
[0009] Furthermore, the thickness of the sealing strip is 3 mm.
[0010] The beneficial effects of this solution are as follows: (1) The sealing strip is detachably connected to the aluminum alloy formwork through a lock, and the steel truss floor deck is placed on the rubber strip. The steel truss floor deck is tightly fitted to the rubber strip through the deadweight of the steel truss floor deck and the deadweight of the concrete after pouring, thereby achieving the purpose of preventing leakage.
[0011] (2) The protrusion on the sealing strip corresponds to the lowest point of the cross section of the steel truss floor deck, so that the contact between the steel truss floor deck and the sealing strip is closer and the leakage prevention effect is better.
[0012] (3) When the concrete pouring of this layer is completed and reaches the demolding strength, the aluminum alloy formwork and rubber strips are removed and used for the next layer of structure, thus achieving reuse. BRIEF DESCRIPTION OF THE DRAWINGS
