The upper surface of the lower plate is connected to the leveling plate through the retaining bars, the bite plate is bite-engaged on the upper surface of the leveling plate, the upper plate is connected to one surface of the bite plate, and rivets are installed on the upper surface of the upper plate; the surface of the lower plate is vertically provided with keel bars that penetrate through to the surface of the upper plate, reinforcement bars are welded on the surface of the keel bars, and the retaining bars are connected to one side of the reinforcement bars through the connecting bars. The bite plate of the utility model, the arrangement of the plate and the keel reinforcement, combines the hard earthquake-resistant structure with the fiber structure to achieve stable earthquake resistance, realizes soft expansion of the hard earthquake resistance of the existing structure, and achieves stable earthquake-resistant effect with the pouring of geopolymer cement. In the existing technology, although a certain splicing effect of the composite plate can be achieved during use, the defect is that the existing cement composite plates are prone to cracking at the joints after splicing, which affects the overall use effect. In view of this, we propose a concrete composite plate with hidden joints to solve the above problem. Utility Model Content
[0004] The utility model aims to solve the problems existing in the background technology and propose a concrete composite board with hidden joints.

[0006] When using the concrete composite slab with hidden seams in this solution, the two panels can be spliced together by joining the snaps and then connecting the through holes with bolts to effectively fix the panels on both sides together. This can hide the connection gap and effectively optimize the stiffness and use effect of the panels after connection.
[0007] Preferably, the buckle is L-shaped, and the surface of one side of the buckle is provided with through holes distributed in a linear array, and the through holes pass through one side of the groove. The L-shaped design can facilitate the connection and fixation of the two sides of the two plates, and the connection seam can be effectively hidden after the two sides are connected by the buckles.
[0008] Preferably, grooves 1 are provided on both sides of the surface of the plate body, and connecting rods are provided inside the grooves 1. The provision of the connecting rods can facilitate the hoisting of the plate body by a hoisting machine, and facilitate the fixing of the steel cable in place.
[0009] Preferably, bolts are provided inside the second groove, and after the two plates are connected, the bolts can be inserted into the through holes, so that the plates on both sides are effectively fixed.
[0010] Preferably, the plate body is provided with steel bars distributed in a linear array inside, and the design of the steel bars can increase the rigidity of the plate body and make it less likely to break.
[0011] Preferably, the buckles can be snapped together, and after the snapping together, the planes on both sides of the plate body are on the same horizontal plane. After the buckles are docked, it can be ensured that the plates are connected in one plane, which can reduce subsequent finishing and polishing.
