[0002] Traditional building formwork needs to be removed after concrete pouring, which is not only time-consuming and laborious, but also easy to cause waste of building materials. The non-removable formwork technology saves this process by integrating with the concrete in one piece, greatly improving the construction efficiency and saving materials.

[0003] In the prior art, the insulation non-removable formwork is generally fixed to the floor slab steel bars with fastening connecting pieces such as cross-slot countersunk self-drilling screws, protruding self-drilling nails, and sleeves. However, it is necessary to drill holes in the non-removable formwork first, which will cause damage to the non-removable formwork. And usually, the hardness of the insulation non-removable formwork is difficult to guarantee, and it cannot provide sufficient anchoring force. At the same time, during the process of tying steel bars, workers are prone to kick the fastening connecting pieces, which is likely to cause the fastening connecting pieces to loosen and fall off.

[0010] On the other hand, the utility model provides a floor insulation and non-removable formwork structure, including the insulation and non-removable formwork, characterized by further including the above-mentioned embedded connecting piece.

[0011] Preferably, at the embedded position of the embedded nut, the crack-resistant net in the insulation and non-removable formwork is locally reinforced by replacing the fiberglass net with a steel wire net.
