Description

Overhanging steel frame structure at windowsill

Technical Field

The utility model relates to an engineering construction field, concretely relates to steel frame construction that encorbelments of windowsill department.

Background

In the engineering construction field, in the attached lifting scaffold (climbing frame) and the actual implementation process of the overhanging scaffold, some special structure structures of the building often have conflicts with the erection of the scaffold. Taking a residential building as an example, the residential building is often designed to be provided with a bay window and an air conditioner plate, so that in the process of building a construction worker, building an external scaffold and installing a climbing frame, the steel section beam of the overhanging scaffold is difficult to place at the position, or the attachment floor structure of the climbing frame is difficult to have a reliable position. The traditional solutions are generally two, one is to change the construction sequence, and the upper bay window structure is constructed after being delayed, so that a space position is reserved for an attachment point of a section steel beam or a climbing frame of the overhanging scaffold; the other kind is that destroy the upper band luffer boards original structure, reserves out the cavity during construction, and the shaped steel roof beam of the scaffold of conveniently encorbelmenting penetrates the window that wafts. The two traditional solutions have certain defects, the construction sequence is changed, and the floating plate on the upper belt is easy to be constructed after being delayed, so that the floating plate structure is not firm, an unstable structure is formed, and the risk is caused to the safety of the structure; the mode of reserving the hole is easy to bring complicated steps to the installation and the dismantling construction of the cantilever scaffold section steel, and the construction efficiency is reduced.

The structural characteristics that have the bay window on with have the air-conditioning board down bring great drawback for the construction implementation, bring structural safety hidden danger for the bay plate structure simultaneously.

Detailed Description

Example (b):

in the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be mechanically coupled, directly coupled, or indirectly coupled through an intermediary, which may be referred to as communication between the two elements. The specific meaning of the above terms in the present invention can be understood as specific cases to those skilled in the art. The technical solution of the present invention is further described with reference to the accompanying drawings and embodiments.

Referring to fig. 1, the overhanging steel frame structure at the windowsill according to the present embodiment mainly includes a steel cantilever beam 1, an attachment support 2, a jig frame 3, and a first spacer 4.

The attachment support 2 is arranged at one end of the steel cantilever beam 1 and is used for being connected with a scaffold for installation so as to be beneficial to rigid consolidation with an external climbing frame or a rigid scaffold to form a stable structure; the jig frame 3 is used for being mounted on the floor surface 100 and used for lifting the steel cantilever beam 1, so that the steel cantilever beam 1 is higher than the upper ribbon bay window plate 201; so can be in order to effectively avoid taking waffle board 201 on, do not change the construction order of taking waffle board 201 on, guarantee to take waffle board 201's structure safety on. The first cushion block 4 is arranged in a gap between the steel cantilever beam 1 and the upper ribbon bay window plate 201 to increase the supporting point of the steel cantilever beam 1 and the contact area with a building structure, so that a soft stress conversion system is formed, and the steel cantilever beam and the building structure can work under better stress.

Preferably, as a preferred embodiment, the second cushion blocks 5 are disposed between the jig frame 3 and the floor 100 and between the jig frame 3 and the steel cantilever 1, so as to increase the contact area between the jig frame 3 and the floor 100 and between the steel cantilever 1 and the jig frame 3, form a soft stress conversion system, and work with better stress

In one embodiment, the jig frame 3 is mounted on the floor 100 by screws 6 to facilitate the mounting and dismounting of the jig frame 3; similarly, the steel cantilever beam 1 is also arranged on the jig frame through a screw 6. That is to say, the moulding bed 3 and the steel cantilever beam 1 are detachably arranged and are assembly members, can be quickly assembled and put into use, can be recycled, improves the work efficiency and reduces the economic cost

As another preferred embodiment, the overhanging steel frame structure at the windowsill further includes a long screw 7, and the long screw 7 connects the steel outrigger 1, the jig frame 3 and the floor 100, so that the whole structure is more stable and safe.

In one embodiment, the sill 200 is cast with foam concrete 202; the foam concrete 202 belongs to a light material, so that the self weight of the building structure is reduced, and the load of the part is favorably reduced. This steel outrigger 1 is the channel-section steel outrigger, and this first cushion 4 is the flitch cushion to do benefit to the timber in construction site.
