Description
Technical Field
The utility model relates to the technical field of building tools, in particular to a pedal for removing combined overhanging I-steel.
Background
In the construction process of a building, due to the necessity of protection of peripheral structures, overhanging scaffolds are often adopted to protect the structural safety in the construction process of the building such as houses and office buildings. Meanwhile, the overhanging scaffold is usually erected by taking I-steel as a supporting point.
In the prior art, super high-rise buildings are more and more, overhanging scaffolds of the building are often divided into a plurality of overhanging sections, and most of first overhanging layers are positioned on a conversion layer or a first standard layer. Meanwhile, with the sales and display requirements of residences, the overhanging scaffold can be dismantled on the middle floor according to actual requirements, and the dismantled top floor can meet construction requirements by means of re-overhanging I-steel.
In the dismantling process of the overhanging I-steel, the hidden safety hazards of dismantling are buried because the bottom is free of an operation platform.
In order to remove the I-steel of the first overhanging layer and the middle overhanging layer, the following methods are often adopted in the prior art:
when the I-steel of the first overhanging layer is dismounted, the outer frame is erected from the ground to the bottom of the overhanging layer, and then the I-steel is dismounted; when the I-steel of the middle overhanging layer is removed, the overhanging outer frame is erected from the next floor surface, and the overhanging structure is used as an operation platform.
The two operation methods have the problems of large engineering quantity, large consumption of manpower and material resources and long construction period.
Therefore, in order to solve the above-mentioned problems, the prior art, such as CN207332281U, is named a mobile operating platform for the removal of overhanging i-steel, comprising a support system and at least four i-steel fastening systems cooperating with the support system; the support system comprises 2 main beams, at least 3 secondary beams and 1 steel ballet; the two main beams are arranged at intervals in parallel, the secondary beams are also arranged at intervals in parallel, the main beams are mutually perpendicular to the secondary beams, a steel basketry is fixedly arranged at one end of each main beam, and an I-steel fastening system is arranged at the other end of each main beam; the I-steel fastening system comprises 1L-shaped round steel and 1 7-shaped round steel, wherein the L-shaped round steel and the 7-shaped round steel are in butt joint to form a square frame, one end of a fixing nut is welded with the 7-shaped round steel, the center of the fixing nut penetrates through the L-shaped round steel, and the fastening nut is used for fixing an operation platform and the I-steel. The operating platform reduces the cost of manpower and material resources and the safety risk of the overhanging I-steel dismantling and shortens the dismantling period.
However, the supporting system of the movable operating platform is formed by enclosing the main beam and the secondary beam into a rectangular supporting frame, a steel ballet used as a pedal is arranged on one side of the supporting system, and a hollow structure is arranged on the other side of the supporting system, so that the standing area of a worker is small, the walking space is small, and the danger of stepping on the ground is existed; when the I-steel fastening system fastens the I-steel, a spanner is needed to rotate a fastening nut so as to fasten the operation platform and the I-steel, and the operation is complex; in addition, the movable operating platform is not provided with a handle for manual support, so that the operation of removing workers is inconvenient, and certain potential safety hazards exist.

When the steel wire rope is detached, the I-shaped steel to be detached is bundled and firm by the steel wire rope, and the I-shaped steel with larger weight and external angle can be directly fixed on the tower crane lifting rope; for the I-steel with lighter weight and a window hole nearby, the steel wire rope can be fixed in the room after being bundled, and the I-steel is pulled into the room after the dismantling is waited to be completed. Thus, the risk of falling of the dismantled I-steel from the high altitude is prevented.
I-steel bolt removal is divided into two cases. The first is that the nut is indoor and the outside is the bolt head and the gasket. The I-steel can be lifted to the ground or pulled into the room only by detaching the nut indoors. The other case is that the nut is outside the room or a bolt in a pre-buried form is adopted. The demolition work is required outdoors, and a worker performs demolition work on the step in the present application. When the nut is inconvenient to detach outdoors, the locking nut can be detached firstly, then the fastening nut is clamped by the thin slice wrench, and then the bolt is screwed out from the room.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant points refer to the description of the method section.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present utility model is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
