Description
技术领域technical field
本实用新型涉及一种复合夹层承载板，具体是一种波纹腹板混凝土复合夹层承载板，属于建筑结构工程领域。The utility model relates to a composite sandwich bearing plate, in particular to a corrugated web concrete composite sandwich bearing plate, which belongs to the field of building structure engineering.
背景技术Background technique
目前，建筑行业和制造产业随着经济的崛起而快速的发展，人们对建筑或制造中所需的承载构件相应的也要求越来越高。而传统建筑行业中，一般承载板为钢筋混凝土板，其自重比较大，且需要现场绑扎钢筋、支模浇筑和养护等，从而导致施工工序繁琐。对于钢结构的承载板，其用钢量大、成本高，同时由于钢板的面外抗弯刚度弱，当承受较大的压力载荷时，钢结构承载板的挠度也会变大，容易发生面外弯曲屈服破坏。At present, the construction industry and manufacturing industry are developing rapidly with the rise of the economy, and people have higher and higher requirements for the load-bearing components required in construction or manufacturing. In the traditional construction industry, the general load-bearing slab is a reinforced concrete slab, which has a relatively large weight, and requires on-site tying of steel bars, formwork pouring and maintenance, etc., resulting in cumbersome construction procedures. For the load-bearing plate of the steel structure, the amount of steel used is large and the cost is high. At the same time, due to the weak out-of-plane bending stiffness of the steel plate, the deflection of the steel structure load-bearing plate will also increase when it bears a large pressure load, which is prone to surface failure. The outer bend yields to failure.
在建筑结构、海洋平台结构、桥梁结构以及船舶或列车制造业中，一般使用金属波纹芯夹层板，但其夹心部分一般只是沿某一方向特定排列，从而导致金属波纹芯夹板在夹心布置方向上夹层板刚度大，而垂直于夹心方向上，夹层板刚度弱，尤其是抗剪强度一般都非常小。当此种夹层板承载板承载较大时，夹层板刚度较弱的方向容易发生剪切破坏，从而导致承载板瞬间失去承载能力，使得结构垮塌，造成重大的人员伤亡和财产损失。In building structures, offshore platform structures, bridge structures, and ship or train manufacturing industries, metal corrugated core sandwich panels are generally used, but the sandwich parts are generally only arranged in a certain direction, resulting in metal corrugated core plywood in the sandwich arrangement direction. The sandwich panel has high rigidity, but in the direction perpendicular to the sandwich core, the sandwich panel has weak stiffness, especially the shear strength is generally very small. When the bearing plate of this kind of sandwich plate bears a large load, shear failure is likely to occur in the direction of weaker stiffness of the sandwich plate, which will cause the bearing plate to lose its bearing capacity instantaneously, causing the structure to collapse, causing heavy casualties and property losses.
