Embodiment 1

[0047] refer to figure 1 and figure 2 , is an anti-seismic floor slab of a steel structure for construction disclosed by the present invention, which is arranged on a steel beam 1. The steel beam 1 includes a main beam 11 and a connecting beam 12, and the connecting beam 12 is connected between adjacent and parallel main beams 11 , the connecting beam 12 is perpendicular to the main beam 11, the main beam 11 is a main beam 11 of I-shaped steel structure, the steel beam 1 is provided with a concrete filling layer 13, and the lower plates of two adjacent main beams 11 are provided with a floor deck 2 , the floor deck 2 is located below the concrete filling layer 13, and the embossing on the surface of the floor deck 2 makes the bonding between the floor deck 2 and the concrete filling layer 13 intimate, so that the floor has a strong bearing capacity; the upper part of the floor deck 2 is set There are connecting components, which are embedded in the concrete filling layer 13 ...

Embodiment 2

[0053] A method for manufacturing a steel structure anti-seismic floor slab for a building. The specific method is: S1: Open two rows of evenly distributed positioning holes 21 at positions close to both ends of the floor deck 2, and each row of positioning holes 21 is parallel to the main beam 11 .

[0054] S2: According to the size of the rectangular interval divided by the main beam 11 by the connecting beam 12, the horizontal bars 31 and the longitudinal bars 32 are fixedly connected to form a reinforcement mesh 3, so that the horizontal bars 31 of the upper and lower reinforcement meshes 3 correspond to the vertical bars up and down , welding a plurality of connecting bars 4 between the upper and lower two steel meshes 3, the upper end of the connecting bars 4 exceeds the height of the steel mesh 3.

[0055] S3: Prefabricated connection assembly, weld the two ends of the transverse rib 31 to the elastic member 71, so that the deformation direction of the elastic member 71...

Abstract

The invention relates to a steel structure anti-seismic floor for building and a manufacturing method thereof, wherein the steel structure anti-seismic floor for building is arranged on the steel beam; the steel beam comprises main beams and a connecting beam, and the lower floor of two adjacent main beams is provided with a floor slab; a connecting assembly is arranged between the two main beams,and the connecting assembly comprises two layers of steel mesh arranged horizontally above and below, and connecting ribs are connected between the two steel meshes, wherein the steel meshes comprisetransverse ribs and longitudinal ribs; the transverse ribs are perpendicular to the main beams, and the two ends of the transverse ribs are fixedly connected with abutting ribs; the transverse ribs are provided with an anti-seismic assembly, wherein the anti-seismic assembly comprises an elastic member and a positioning reinforcing bar; the elastic member is fixedly connected between the abuttingribs and the transverse ribs, and the positioning reinforcing bar is fixedly connected to the end of the elastic member, away from the transverse ribs; the abutting ribs are fixedly connected to theposition of the positioning reinforcing bar near the upper and lower ends; the steel beam is provided with a concrete filling layer, and the connecting assembly is embedded inside the concrete fillinglayer. The steel structure anti-seismic floor for building has the advantages of improving the integrity between the floor slab and the steel beam and the earthquake resistance of the floor.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a steel structure anti-seismic floor plate for construction and a manufacturing method thereof. Background technique [0002] The steel structure is a structure mainly made of steel (steel plate and section steel). Compared with the traditional concrete structure and masonry structure, it has stable performance, light weight, high strength, and short construction period. It has been widely used in my country's modernization construction . [0003] In traditional floor construction, wooden boards are mostly used as the pouring formwork of the floor, and some simple structural treatment is done at the connection between the floor and the steel beam. [0004] Once vibration or shaking occurs, it is very easy to cause the fixed connection between the floor slab and the steel beam to break, making the integrity between the floor slab and the steel beam and the seismic...
