High-toughness concrete and steel structure building floor slab
The invention discloses high-toughness concrete and a steel structure building floor slab. In a composite toughening agent of the high-toughness concrete, the main chain of a molecular chain of ethylene propylene diene monomer does not contain double bonds and only a small amount of side groups contain double bonds; styrene is added for grafting to form long-chain macromolecules, so good toughening effect is obtained; through combination with algal polysaccharides and reaction with urea, a polymer network structure is formed, so on the premise of ensuring hardness, the toughening effect is further improved; and the composite toughening agent is matched with quick lime and blast furnace slag, so the strength, moisture resistance and durability of the concrete can be improved, and the toughness, strength and service life of the concrete and the steel structure floor slab are improved. According to the invention, the edges of the floor slabs are provided with connecting blocks and connecting holes, connecting rods driven by gear and rack structures are arranged on connecting plates, and the connecting rods can be driven by gears and racks to be inserted into the connecting holes during floor slab installation and construction, so adjacent floor slabs are conveniently and quickly assembled and connected, and the installation and construction efficiency of the floor slabs is improved.
本发明公开了一种高韧性混凝土及钢结构建筑楼板，高韧性混凝土的复合增韧剂中，由于三元乙丙橡胶分子链主链不含双键，仅少量侧基含双键，一方面通过加入苯乙烯接枝形成长链大分子，增韧效果好，另一方面通过与海藻多糖结合，配合尿素反应形成高分子网状结构，在保证硬度的前提下，增韧效果进一步提高；复合增韧剂与生石灰、高炉矿渣配合，可提高混凝土的强度、防潮耐久性，从而提高混凝土及钢结构楼板的韧性、强度以及使用寿命；在楼板的边沿设置有连接块和连接孔，在连接板上设置有齿轮齿条结构驱动的连接杆，可在楼板安装施工时，通过齿轮齿条驱动连接杆插装于连接孔内，从而方便相邻楼板的快速拼装连接，提高楼板的安装施工效率。
