Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of building materials and building construction, more particularly to the technical field of the fabricated prefabricated component with light weight and increased honeycomb core. BACKGROUND
[0002] In the cast-in-place main structure construction process, the floor generally adopts solid structure, and after the reinforcement binding is completed, the concrete is poured to form the reinforced concrete main structure floor. Due to the high density and heavy weight of the solid floor composed of reinforced concrete, the column and beam section need to be increased, resulting in a heavy self-weight of the entire building, affecting the bearing capacity of the building and increasing the engineering cost.
[0003] Especially in some large-span spaces, in order to increase the use space and reduce the floor self-weight, the conventional dense rib floor-cele design is adopted, and the use amount of concrete and other materials is reduced by setting the inner cavity. During the pouring of the floor, the pressure of the concrete on the honeycomb core is large, which easily causes the honeycomb core to crack, resulting in rework and affecting the construction quality. The ordinary honeycomb core is made of cement fiber board and GRC board to reduce the self-weight, but when it is very thin, the strength is not enough, which easily leads to damage. The cast-in-place assembly type can ensure the strength and span, but it leads to a heavy weight and is not convenient for transportation, resulting in increased cost.
[0004] If the honeycomb core is light in weight and high in strength, and can realize assembly type construction, it becomes an urgent problem to be solved. CONTENT OF THE UTILITY MODEL

[0014] The transverse reinforcing bars are located in the transverse position of the honeycomb core bottom plate and are made of steel bars (steel bar strength grade and specification, which can be determined according to the shape and size of the honeycomb core). Through the cooperation of longitudinal steel bars and transverse steel bars, a single-layer two-way reinforcing system is formed, which, in combination with fine stone concrete, realizes crack resistance and avoids cracking of the honeycomb bottom plate due to the thinness of the honeycomb core bottom plate, thereby affecting the final construction quality.
