Description

Overhang net scaffolding on the steel frame of a large power station boiler

technical field

The utility model relates to a scaffold, in particular to a scaffold erected on the steel frame of a large-scale power station boiler.

Background technique

In the installation process of the steel structure of large-scale power plant boilers, it is necessary to set up the external hanging net. The traditional pure scaffolding method is time-consuming and laborious to set up. The amount of shelf materials is large, the weight is heavy, and the space in the steel frame is occupied, which affects the equipment inside the steel frame. installation.

Contents of the invention

The utility model provides an overhanging mesh scaffolding on the steel frame of a large-scale power station boiler, which solves the technical problem that the overhanging beams of the existing steel frame occupy a large space in the steel frame.

The utility model solves the above technical problems through the following technical solutions:

An overhang net scaffold on the steel frame of a large-scale power plant boiler, including the left upper eaves of the I-shaped steel beam, the right upper eaves of the I-shaped steel beam, the left steel pipe sleeve, the right steel pipe sleeve, the left L-shaped clamping plate and the right L-shaped clamping plate, the left The outer surface of the pipe wall of the steel pipe sleeve is fixedly connected with a left L-shaped clamping plate, and the outer surface of the pipe wall of the right steel pipe sleeve is fixedly connected with a right L-shaped clamping plate. In the left card groove composed of L-shaped clamping plates; the outer surface of the pipe wall of the right steel pipe sleeve is fixedly connected with a right L-shaped clamping plate, and the right upper eaves of the I-shaped steel beam are clamped on the right steel pipe sleeve and the right L-shaped clamping plate. In the right draw-in slot, there is an external steel pipe connected between the left steel pipe sleeve and the right steel pipe sleeve.

A left top wire hole is arranged on the left steel pipe sleeve, and a left top wire is arranged in the left top wire hole. A right jacking wire is arranged in the jacking wire hole, and the right jacking wire is connected with the overhanging steel pipe; a diagonal brace is arranged between the overhanging steel pipe and the I-shaped steel beam.

The utility model has the functions of saving time, labor and materials for erection, ensures the normal use of the internal structure of the steel frame, meets the safety requirements of the external cantilever beam, and has good popularization value.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in detail:

An overhang net scaffold on the steel frame of a large-scale power plant boiler, including the left upper eaves of I-shaped steel beams 1, the right upper eaves of I-shaped steel beams 7, the left steel pipe sleeve 2, the right steel pipe sleeve 8, the left L-shaped clamping plate 3 and the right L Shape clamping plate 9, the left end of the upper top plate of I-shaped steel beam is the left upper eaves 1 of I-shaped steel beams, and the right end of the upper top plate of I-shaped steel beams is the right upper eaves 7 of I-shaped steel beams, the pipe wall of left steel pipe cover 2 A left L-shaped clamping plate 3 is fixedly connected on the outer surface, and a right L-shaped clamping plate 9 is fixedly connected on the outer surface of the pipe wall of the right steel pipe sleeve 8. In the left draw-in groove 4 that L-shaped clamping plate 3 forms; The pipe wall outer surface of right steel pipe sleeve 8 is fixedly connected with right L-shaped clamping plate 9, and the right upper eaves 2 of the I-shaped steel beam are clamped on the right steel pipe sleeve 8 and the right In the right draw-in groove 10 that L-shaped clamping plate 9 forms, between left steel pipe sleeve 2 and the right steel pipe sleeve 8, a steel pipe 11 for overhanging is connected.

The left top wire hole 5 is provided on the left steel pipe sleeve 2, the left top wire 6 is arranged in the left top wire hole 5, the left top wire 6 is top connected with the outer steel pipe 11, and the right steel pipe sleeve 8 is provided with The right top wire hole 12 is provided with a right top wire 13 in the right top wire hole 12, and the right top wire 13 is connected with the outer steel pipe 11; a diagonal brace is arranged between the outer steel pipe 11 and the I-shaped steel beam.

When the utility model is in use, the steel pipe kits are respectively clamped on both sides of the H-shaped steel upper wing plate of the steel frame, the scaffold steel pipe is inserted into the two sleeve pipes, and the screw bolts are tightened to lock. "The falling height specified in "can be adjusted arbitrarily. If the length of the overhang exceeds 2 meters, a diagonal support riser should be installed under the overhanging steel pipe to enhance its rigidity.
