Background
The scaffold climbing net piece is an external scaffold which is erected at a certain height, attached to an engineering structure, can climb or descend layer by layer along with the engineering structure by virtue of self lifting equipment and devices and is provided with an anti-overturning and anti-falling device. In the building construction field, the various types of protection of wide use climb a net piece, and along with the utilization of climbing a net piece lasts to increase, climb a net piece and suffer each other's attention thereupon, the research and development of climbing a net piece is followed and is climbed the utilization of frame and necessary and change and improve. The climbing frame net piece can be divided into: steel sheet climbs a net piece, zinc-plated climbs a net piece, a plastic-sprayed plate climbs a net piece, aluminum plate climbs a net piece etc. divide into according to the hole type: round holes, rectangular holes, quincuncial holes, rhombic holes, triangular holes, hexagonal holes and the like. The climbing frame net piece is continuously improved, the weight of the climbing frame net piece is gradually reduced when the aperture ratio is increased, the structural design is more and more scientific and reasonable, and better economic benefit is obtained. However, the existing climbing frame net sheets are all modularized climbing frame net sheets, the arrangement of the climbing frame net sheets at special positions such as grouping seams, tower crane attachment arms and the like is always a key difficult point to be solved, a certain effect can be achieved by fixing the climbing frame net sheets by using iron wires after cutting, but the climbing frame net sheets are not beneficial to construction, faults are easy to occur in the using process, great potential safety hazards exist, and the popularization and the application of the climbing frame net sheets are limited.
At present, the mesh protection of the creeper at the position of the grouping seam, which is commonly used in the industry, is realized by fixing a keelless mesh through an iron wire, and the processing method of the prior art for the position of the grouping seam is generally as follows: two long edges of the keel-free net pieces cut from the large-size modular net pieces are connected with the modular net pieces on two sides of the grouping seams through iron wires respectively, so that the climbing frame is guaranteed to be in an externally closed state, and safety construction of workers is guaranteed.

Specifically, a first keel frame first side 2011, a first keel frame second side 2012, a first keel frame third side 2013 and a first keel frame fourth side 2014 are connected in a welding manner to form a first keel frame 201, a second keel frame first side 2021, a second keel frame second side 2022, a second keel frame third side 2023 and a second keel frame fourth side 2024 are connected in a welding manner to form a second keel frame 202, a third keel frame first side 2031, a third keel frame second side 2032, a third keel frame third side 2033 and a third keel frame fourth side 2034 are connected in a welding manner to form a third keel frame 203, the first side 2041 of the fourth keel frame, the second side 2042 of the fourth keel frame, the third side 2043 of the fourth keel frame and the fourth side 2044 of the fourth keel frame are connected by welding to form the fourth keel frame 204.
Preferably, the welding mode related to the invention is carbon dioxide gas shielded welding, the height of the welding seam is 1.2 times of that of the base metal, and the welding is firm.
When the third keel frame 203 to which the third mesh 103 is attached and the fourth keel frame 204 to which the fourth mesh 104 is attached are closed, namely, the third keel frame 203 for installing the third mesh sheet 103 is buckled on the first keel frame 201 for installing the first mesh sheet 101, the fourth keel frame 204 for installing the fourth mesh sheet 104 is buckled on the second keel frame 202 for installing the second mesh sheet 102, the lifting operation of the climbing frame body can be realized, after the lifting is finished, the third keel frame 203 for installing the third net piece 103 and the fourth keel frame 204 for installing the fourth net piece 104 are opened, by adjusting the third keel frame 203 for installing the third mesh 103 and the fourth keel frame 204 for installing the fourth mesh 104 to form a certain angle with the first keel frame 201 for installing the first mesh 101 and the second keel frame 202 for installing the second mesh 102, so as to realize the full sealing at the position of the grouping seam, thereby realizing the protection at the position of the grouping seam.
In summary, the invention has the following advantages:
(1) adopt the mode that can open and shut, the net piece that need not locate the group seam position when climbing frame support body and promoting is demolishd and is stacked, only needs to open the third keel frame 203 of installation third net piece 103 and the fourth keel frame 204 of installation fourth net piece 104, can accomplish the lift operation of support body, only need close once more after the lift is accomplished the third keel frame 203 of installation third net piece 103 and the fourth keel frame 204 of installation fourth net piece 104 can, it is convenient, safe, high-efficient to use.
(2) The plate-type hinge is adopted to replace a traditional pin shaft to serve as the turning center of the third keel frame 203 for installing the third mesh sheet 103 and the turning center of the fourth keel frame 204 for installing the fourth mesh sheet 104, so that the assembly is convenient, the traditional pin shaft is often difficult to insert due to hole alignment when being installed and dismantled, the subsequent installation progress is influenced, the uncertain factors of the traditional pin shaft are relatively large, and potential safety hazards exist.
(3) With first keel frame 201, second keel frame 202, third keel frame 203, fourth keel frame 204 through board-like hinge welding together, make this can open and shut climb a net piece and climb a support body and form a whole, improved the wholeness and the stability of climbing a support body to open and shut conveniently, can effectively avoid traditional packet seam position department net piece to need to demolish the potential safety hazard that high altitude construction such as stacking produced through the manual work.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
