Description

Technical Field

[0001] The utility model belongs to the technical field of building components, in particular to an assembled integral bidirectional dense-ribbed composite floor slab. Background Art

[0002] The assembled integral two-way dense-rib composite floor is a new type of floor technology, which combines the advantages of assembly technology and cast-in-place concrete dense-rib hollow floor technology. It is connected by prefabricated dense-rib bottom plates in a reliable way and concrete is poured on site to form an integral assembled concrete structure.

[0003] The floor is cast by precast concrete base plate, precast cavity components and precast steel skeleton. The bottom structure of the base plate floor has a certain thickness and strength. As the foundation of the composite floor, these components form a series of cavities on the base plate, which helps to reduce the deadweight of the floor and increase the thermal insulation and sound insulation performance of the floor. Precast steel skeleton: The steel skeleton is an important part of the floor structure. It provides skeleton support for the floor and works with the base plate and cavity components to ensure the overall stability of the floor.

[0004] When the floor is in use, the extended steel bars can provide a certain support to the floor. The frame at the bottom of the floor is a plane structure. The floor body has a large mass, and the frame reinforcement is generally composed of mutually perpendicular ribs. The force is concentrated on the connection points of the ribs, resulting in poor load-bearing effect, which affects the use effect. Therefore, an assembled integral bidirectional dense-rib composite floor is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the shortcomings of the prior art, the frame of the base plate is a plane structure. When in use, the mass of the floor slab body is relatively large, and the composed frame ribs are generally composed of mutually perpendicular ribs. The force is concentrated on the connection points of the ribs, the bearing effect is poor, and the use effect is affected. The utility model proposes an assembled integral bidirectional dense-rib composite floor slab. By arranging a truncated cone frame between the upper and lower groups of bearing nets, the bearing force of the entire floor slab can be better dispersed. The different dispersion angles can improve the bearing strength of the floor slab and reduce the overall mass. During pouring, the hollow structure is a trumpet-mouth structure with a small upper part and a large lower part, which is easier to demould, and multiple circular hollow structures are more beautiful.

[0006] The technical solution adopted by the utility model to solve the technical problem is an assembled integral bidirectional dense-rib composite floor, comprising: a plate body and a longitudinal rib beam, wherein the longitudinal rib beam and the transverse rib beam are arranged in a cross-shaped structure;

[0007] The plate body is located in the intersection of the longitudinal rib beam and the transverse rib beam, and two adjacent side edges of the plate body are respectively fixed to the side edge of the longitudinal rib beam and the side edge of the transverse rib beam;

[0008] A trumpet-shaped hollow top is provided at the bottom of the plate body, and a ring-shaped bracket is formed by pouring concrete on the hollow top;

[0009] The annular support comprises a first annular stirrup and a second annular stirrup, wherein the first annular stirrup is located below the second annular stirrup, and the axes of the first annular stirrup and the second annular stirrup are in the same straight line;

[0010] Connecting bars are arranged in an annular array between the first annular stirrups and the second annular stirrups, and a truncated cone frame is provided, which can better achieve the dispersion of the bearing force of the entire floor slab. Different dispersion angles can improve the bearing strength of the floor slab and reduce the overall mass.

[0011] Preferably, rib longitudinal ribs are disposed transversely through the interior of the transverse ribs, and rib longitudinal ribs are also disposed transversely through the interior of the longitudinal ribs.

[0012] Preferably, gate-type rib stirrups are provided on the top side surfaces of the longitudinal ribs and the transverse ribs, and both ends of the rib stirrups are respectively cast inside the longitudinal ribs and the transverse ribs, so as to achieve integral forming.

[0013] Preferably, the longitudinal ribs and the second transverse ribs are cross-arranged on the periphery of the first annular stirrups, and the first annular stirrups are respectively bound to the first longitudinal ribs and the second transverse ribs at their close points by tying wires, the first transverse ribs and the second longitudinal ribs are cross-arranged, and the second longitudinal ribs and the first transverse ribs are arranged above the second annular stirrups, and the second annular stirrups are respectively bound to the second longitudinal ribs and the first transverse ribs at their close points by tying wires.

[0014] Preferably, the second longitudinal ribs and the second transverse ribs are connected and bound by second upper and lower connecting stirrups, and the first transverse ribs and the second transverse ribs are connected and bound by first upper and lower connecting stirrups.

[0015] Preferably, the intersection of the second longitudinal rib and the first transverse rib is bound by a wire tie, and the intersection of the first longitudinal rib and the second transverse rib is bound by a wire tie to ensure the stable connection of the overall frame.

[0016] The utility model is beneficial in that:

[0017] The utility model forms an upper load-bearing net by the intersection of the second longitudinal rib and the first transverse rib, and forms a bottom load-bearing net by the intersection of the first longitudinal rib and the second transverse rib, so as to realize the lifting of the truncated cone frame composed of the first annular hoop reinforcement, the second annular hoop reinforcement and the connecting ribs. The truncated cone frame is arranged between the upper and lower groups of load-bearing nets, which can better realize the dispersion of the bearing force of the whole floor slab. The different dispersion angles can improve the bearing strength of the floor slab and reduce the overall quality. During casting, the hollow structure is a trumpet-mouth structure with a small top and a large bottom, which is more convenient for demoulding.
