The technical scheme for realizing the purpose is as follows: a steel springboard for a scaffold comprises a steel springboard panel, wherein two sides of the steel springboard panel in the width direction are bent downwards to form vertical side boards, the lower parts of the vertical side boards are bent inwards to form side boards horizontally, flange round holes and groove-shaped longitudinal reinforcing ribs are distributed on the steel springboard panel, end sealing boards are arranged at two ends of the steel springboard panel, the upper ends of the end sealing boards are bent to form hooks and baffles matched with small cross bars of the scaffold, the hooks are L-shaped cross-section hooks provided with hook horizontal boards and hook vertical boards, the distance between the inner side surfaces of the hook vertical boards of the L-shaped cross-section hooks and the outer side surfaces of the end sealing boards is the sum of the diameter of the small cross bars of the scaffold and the thickness of the hook vertical boards, the upper surfaces of hook horizontal boards of the L-shaped cross-section hooks are flush with the upper surfaces of the steel springboard panel, and the opposite sides of the hook horizontal boards of the L-shaped cross-section hooks are provided with baffle embedding gaps, the scaffold is characterized in that a hook embedding gap is arranged between the baffle and the hook, the upper surface of the baffle is flush with the upper surface of the steel springboard panel, one end edge of the baffle is flush with one side edge of the steel springboard panel, the width of the baffle is the sum of the radius of the small cross rod of the scaffold and the thickness of the vertical plate of the hook, and the hook and the baffle at the two ends of the steel springboard panel are symmetrically arranged by taking the center of the steel springboard panel as a symmetrical midpoint.

In the steel springboard for the scaffold, the two edges of the hook opposite to the baffle are respectively set to be oblique edges to form a trapezoidal hook embedding gap.

The utility model has the advantages that:

1. the L-shaped cross section hook integrally bent with the end sealing plate is adopted, and the problem of low connection strength of the welding hook is solved.

2. After the steel springboard is hung on the small cross bar of the scaffold and is installed, the horizontal plate of the hook is matched with the baffle to form a steel springboard end connection plane, so that the paved steel springboard pavement can form a complete flat surface.

3. The hooks and the baffles at the two ends of the steel springboard are symmetrically arranged by taking the center of the steel springboard panel as a symmetrical midpoint, so that the two ends of the steel springboard are not different from one another from head to tail, and the production and the installation of the steel springboard are facilitated.

4. After the installation of the steel gangway is completed, the hook vertical plate of the hook with the L-shaped section is clamped between the end sealing plate and the small cross rod of the scaffold, so that the stability and the safety of the installation of the steel gangway can be improved.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1, the steel springboard for the scaffold comprises a rectangular steel springboard panel 1, wherein vertical side plates 11 are respectively formed by bending downward two sides of the steel springboard panel 1 in the width direction, and side plates 12 are respectively formed by horizontally bending inward the lower parts of the vertical side plates 11. The steel springboard panel 1 is distributed with antiskid flange round holes 13 and groove-shaped longitudinal reinforcing ribs 14, and the grooves of the longitudinal reinforcing ribs 14 are trapezoidal grooves and are provided in two numbers. The two ends of the steel springboard panel 1 are respectively welded with the end sealing plates 2, and the upper ends of the two end sealing plates 2 are respectively bent outwards to form a hook 21 and a baffle 22 matched with the small cross rod of the scaffold. Couple 21 is for having the L shape cross-section couple of couple horizontal plate part and couple vertical plate part, the interval size of the couple vertical inboard side of L shape cross-section couple and 2 lateral surfaces of end shrouding is the external diameter size of scaffold frame little horizontal pole and the board thickness size sum of the couple vertical plate, flush above the couple horizontal plate of L shape cross-section couple and above the steel springboard panel 1, the couple horizontal plate of L shape cross-section couple is equipped with the breach that supplies the baffle 22 embedding of the steel springboard that links up with baffle 22 with the side of carrying on the back of the body, be equipped with the breach that supplies the couple 21 embedding of the steel springboard that links up between baffle 22 and the couple 21, the higher authority of baffle 22 flushes with the upper surface of steel springboard panel 1 and one side of this baffle 22 flushes with a side of steel springboard panel 1. The width dimension of the baffle plate 22 is the sum of the radius dimension of the small cross bar of the scaffold and the plate thickness dimension of the vertical plate of the hook. The hooks 21 and the baffles 22 at the two ends of the steel springboard panel 1 are symmetrically arranged by taking the center of the steel springboard panel 1 as a symmetrical midpoint.

As shown in FIG. 2, two longitudinally adjacent steel gangplank are respectively connected to the same scaffold small cross bar through respective hooks 21 and baffles 22 to complete the installation of the steel gangplank, and form the end connection plane of the two adjacent steel gangplank.
