Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Examples

As shown in fig. 1 to 5, steel bar truss floor carrier plate, including fire prevention floor carrier plate combination 1, still include steel bar truss 4 and

concrete floor

6, 1 inside pre-buried reinforcing bar net 2 and a plurality of support 3 of fire prevention floor carrier plate combination, steel bar truss 4 comprises a plurality of steel bar welding, concrete floor 6's inside pre-buried reinforcing bar net two 5 that have, steel bar truss 4's upper end and reinforcing bar net two 5 are through pricking silk fixed connection, steel bar truss 4's lower extreme is through pricking silk and 3 fixed connection of support.

In this embodiment, the first reinforcing mesh 2 and the second reinforcing mesh 5 are formed by a plurality of reinforcing bars which are crisscrossed and are in a net shape, and crisscrossed reinforcing bar intersections are fixedly connected by binding wires.

In this embodiment, support 3 is the V font, and the both ends of support 3 are pre-buried inside fire prevention building carrier plate combination 1, the tip end of support 3 exposes to 1 outsides of fire prevention building carrier plate combination.

In this embodiment, the steel bar truss 4 is formed by welding a plurality of bent steel bars, and the bent steel bars are in a sine wave shape.
