The invention discloses a concrete prefabricated laminated slab which comprises a laminated concrete slab, a prestressed concrete slab and a reinforcing rod, the reinforcing rod is fixedly installed between the laminated concrete slab and the prestressed concrete slab, and a transverse steel bar is fixedly installed at the upper end of the prestressed concrete slab. The transverse steel bars penetrate through the reinforcing rods. When a pipeline is installed, the pipeline penetrates through the lower end of an arc-shaped plate, then a user rotates a second screw rod through an operation block, at the moment, a positioning rod moves downwards along a positioning groove, so that the second screw rod drives the arc-shaped plate to move downwards, and the arc-shaped plate is prevented from rotating when moving up and down through the positioning rod and the positioning groove; and the pipeline is fixed until the rubber pad at the lower end of the arc-shaped plate extrudes the position of the outer side wall of the pipeline, so that damage installation on the laminated plate is not needed during pipeline installation, the integrity of the laminated plate is guaranteed, and the service life of the laminated plate is prolonged.
本发明公开了一种混凝土预制叠合板，该叠合板包括叠合混凝土板、预应力混凝土板和加固杆，所述叠合混凝土板和预应力混凝土板之间位置固定安装设置有加固杆，所述预应力混凝土板上端位置固定安装设置有横向钢筋，所述横向钢筋穿过加固杆。本发明安装管道时，将管道穿过弧形板下端位置，然后使用者通过操作块转动第二螺杆，此时定位杆沿着定位槽向下移动，从而使得第二螺杆带动弧形板向下移动，并且通过定位杆与定位槽防止弧形板在上下移动时转动，直到弧形板下端橡胶垫挤压管道外侧壁位置，使得管道被固定，从而安装管道时无需在叠合板上进行破坏安装，保证叠合板的完整性，从而延长叠合板的使用寿命。
