Concrete composite board

Abstract

The invention discloses a concrete composite board which comprises a composite board body, and the composite board body comprises a connecting frame and a concrete filling body. The number of the connecting frames is two. A telescopic adjusting mechanism is arranged between the two connecting frames; and a permeation connecting mechanism is arranged at the tail end of the connecting frame. When a composite board body is connected and butted into a corresponding mounting position through the telescopic adjusting mechanism, the sliding convex column at the connecting frame is extruded to be linked with the cutter ends on the paired extrusion plates to vertically cut into the closed colloid on the corresponding side of the connecting frame; meanwhile, the resilience force of the driving spring is also released in a linkage manner, so that the extrusion plate drives the cutter end to cut a crack along the closed colloid, and meanwhile, the pressurizing sliding plate presses the closed colloid in a linkage manner in the transverse moving process of the extrusion plate; therefore, the quick-dry adhesive in the piston cavity can permeate into the gap at the splicing end of the composite board body from the crack on the sealing colloid.

Description

technical field [0001] The invention relates to the technical field of concrete composite panels, in particular to a concrete composite panel. Background technique [0002] Concrete composite slab is a kind of slab mainly composed of concrete materials and other materials, which rely on the characteristics of other mixed materials to enhance or expand some characteristics and functions of concrete itself, so as to apply to more scenarios. However, the shortcomings of general concrete composite panels are that: general concrete composite panels are manufactured according to the space to be installed or the size of the docking object during manufacture. Once the manufacture is completed, the size is fixed. When the butt end of the composite board is spliced ​​with the relevant butt parts or the installation position, it is still easy to produce small gap errors, and such errors are difficult to make up from the outside of the connection position, which will affect the connecti...

However, the shortcomings of general concrete composite panels are that: general concrete composite panels are manufactured according to the space to be installed or the size of the docking object during manufacture. Once the manufacture is completed, the size is fixed. When the butt end of the composite board is spliced ​​with the relevant butt parts or the installation position, it is still easy to produce a small gap error, and it is difficult to make up for such errors from the outside of the connection position, which will affect the connection accuracy
