Problems solved by technology

[0004] However, the above patents still have the following technical problems: (1) cavities are formed between the slabs, which reduces the integrity of the slabs, thereby greatly reducing the seismic performance of the slabs; (1) cavities are formed between the slabs, resulting in waterproofing The anti-seepage performance is poor, which makes the water and electricity pipelines more prone to corrosion and damage; (3) The cement fiber board is directly installed on the upper flange of the steel beam and the upper surface of the concrete column, and the connection strength is low and the reliability is low
