Detailed Description
The technical scheme of the invention is clearly and completely described in the following with reference to the accompanying drawings.
Referring to fig. 1, the inclined ladder for a construction scaffold according to the present invention includes side frame steps and fixing members. The side frame is composed of four parallel steel pipes serving as inclined straight rods, the four steel pipes are divided into two groups and are respectively positioned on two sides of the inclined ladder, the two steel pipes of each group are arranged up and down, the steel pipe positioned above is an upper inclined straight rod, the steel pipe positioned below is a lower inclined straight rod, and the two groups of steel pipes are the same in height. Evenly on every steel pipe through the several mounting with the steel pipe lock joint on the scaffold, the mounting is scaffold fastener in this embodiment, and mounting quantity is two on every steel pipe.
The pedal comprises two beams and a stepping structure which are parallel to each other. Wherein the crossbeam is the steel pipe, and the length of two crossbeams is longer than the width of inclined ladder, and the interval of two crossbeams is 240 mm. The stepping structure is a rectangular grid and consists of a twisted steel bar perpendicular to the cross beam and a twisted steel bar parallel to the cross beam. The threaded steel bars perpendicular to the cross beam are welded on the cross beam, and the threaded steel bars parallel to the cross beam are welded on the threaded steel bars perpendicular to the cross beam. The length of the rectangular grid is the width of the ramp, which in this embodiment is 240 mm. Because the length of the structure of marking time is shorter than the length of crossbeam, the both ends of crossbeam are the overhang, and the overhang of every crossbeam is fixed on the steel pipe as the side frame through the connecting piece, and the connecting piece of this embodiment is scaffold fastener.
In this embodiment, when the inclined ladder is installed for the construction scaffold, at first, the steel pipe that will regard as the side frame is fixed on the scaffold in the inclined ladder both sides with required inclination respectively through the mounting, and the mounting is the scaffold fastener. Two steel pipes at the same side of the inclined ladder are in a group, and the two steel pipes in each group are parallel to each other and are arranged up and down. Two groups of steel pipes on two sides of the channel are parallel to each other and are arranged at the same height. The scaffold fastener on every steel pipe has two, arranges according to the structure of scaffold. The pedal is a formed component and comprises two steel pipes which are longer than the width of the inclined ladder and are used as cross beams. One group is a twisted steel bar vertical to the beam, and two ends of the twisted steel bar are fixed on the beam through welding. The other group of the twisted steel bars parallel to the cross beam is welded on the twisted steel bars vertical to the cross beam, and the two groups of the twisted steel bars form a rectangular network, namely a stepping structure. The part of the stepping structure, which is longer than each cross beam, is a protruding end, the protruding end is buckled on a steel pipe serving as a side frame through a scaffold fastener, four corners of each pedal are respectively fixed on four steel pipes serving as the side frames, and the stepping structure is in a horizontal state. A plurality of pedals are uniformly arranged on each inclined ladder in parallel. A plurality of connected inclined ladders are arranged on one inclined ladder channel according to the requirement.

After the scaffold is adjusted by the inclined ladder, the original length may not meet the requirement, and the number of the inclined ladders can be increased or reduced according to the requirement.
When the construction scaffold is disassembled by the inclined ladder, firstly, the fastening piece for connecting the cross beam and the side frame is loosened, and the pedal is taken down from the side frame; and secondly, loosening the fastening piece on the cross beam and taking the fastening piece off the cross beam. And finally, loosening the fastening pieces of the side frame and the scaffold, and respectively taking down the four steel pipes of the side frame. The dismounting of the scaffold inclined ladder is completed.
When the construction scaffold is loaded and transported by the inclined ladder, the pedals and the side frames can be respectively piled together, so that the space of a transport tool is saved.
The side frame of the inclined ladder for the scaffold is buckled on the scaffold through the buckling pieces, so that the angle of the inclined ladder for the scaffold can be adjusted in situ, and the pedal is buckled on the side frame through the buckling pieces and can be adjusted to be horizontal after the angle of the inclined ladder is changed.
In the above embodiment, the number of the fasteners between the steel pipes as the side beams and the scaffold can be increased, and the number of the fasteners between the steel pipes of the side beams and the scaffold is increased, which means that the stress points of the scaffold inclined ladder for construction are increased, and the safety performance of the inclined ladder is improved by more stress points.
In an alternative embodiment, the pedal may be a separate component of the steel pipe as the cross beam, and the step structure is a rectangular grid structure in which ear hooks are formed at both ends of the steel bar perpendicular to the steel pipe as the cross beam. After the steel pipe as the cross beam is fastened to the steel pipe as the side frame, the rectangular lattice structure is fastened to the steel pipe as the cross beam by the ear hook.
In the above embodiment, the width of the rectangular grid may be replaced by any one of the widths of 240mm to 300 mm.
In the above embodiment, the rebar perpendicular to the cross beam may be welded to the cross beam instead of being fastened to the cross beam as the rebar perpendicular to the cross beam. In the above embodiment, the two ends of the rebar perpendicular to the steel pipe serving as the cross beam are provided with the ear hook portions, and the ear hook portions are welded to the steel pipe serving as the cross beam. The ear hook part enlarges the welding range of the cross beam and the twisted steel, and further ensures the stability of the connection of the stepping structure and the cross beam.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
