Assembly type inner wall plate
The invention discloses an assembly type inner wall plate. The assembly type inner wall plate comprises at least two wall bodies which are mutually spliced in the vertical direction; at least one common reinforcing steel bar is arranged in each wall body; at least one prestressed reinforcing steel bar is arranged in each wall body; and the number of the common reinforcing steel bars and the number of the prestressed reinforcing steel bars of the adjacent wall bodies are the same. The common reinforcing steel bars of one wall body and the common reinforcing steel bars of the adjacent wall body are vertically and oppositely arranged and fixedly connected, and the prestressed reinforcing steel bars of one wall body and the prestressed reinforcing steel bars of the adjacent wall body are vertically and oppositely arranged and fixedly connected. The prestressed reinforcing steel bars are additionally arranged on the adjacent wall bodies, during use, the stress change amplitude caused by loading or unloading is relatively small, the fatigue resistance of the component can be improved, and the situation that cracks possibly occur at the joint of the adjacent wall bodies or the cracks appear later can be avoided; and common reinforcing steel bars and prestressed reinforcing steel bars are combined for use, so that the requirement of overall strength can be met, and therefore, the construction speed can be increased by reducing the number of the prestressed reinforcing steel bars on the premise of meeting the strength.
本发明公开了一种装配式内墙板，包括至少两块沿竖直方向相互拼接的墙体，墙体内设置有至少一条普通钢筋，墙体内设置有至少一条预应力钢筋，相邻墙体的普通钢筋、预应力钢筋的数量均相同，墙体的普通钢筋与相邻墙体的普通钢筋上下正对设置且固定连接，墙体的预应力钢筋与相邻墙体的预应力钢筋上下正对设置且固定连接。本发明在相邻墙体上增设预应力钢筋，在使用时，因加荷或卸荷所引起的应力变化幅度相对较小，可提高构件的耐疲劳性能，使得相邻墙体的连接处可能不出现裂缝或者裂缝较迟出现的情形，且将普通钢筋和预应力钢筋结合使用足以满足整体强度的需求，因此，在满足强度的前提下减少预应力钢筋的数量能提高施工速度。
