Lower section of cornicing is suspended on, the speed of building of this suspension platform is improved, the protection face of setting ensure that user outstanding using this
Hang safety when platform.
Build above-mentioned steel structure the invention also discloses a kind of and cornice the method for exterior trim surface construction suspension platform, including it is as follows
Step：
1. production unit section；
The preparation method of unit section is：
First, according to cornice 1 length, prepare at least one truss, the length ratio of truss cornices 400 more than length ~
600mm, preferably 500mm；When truss is prepared, the lower boom of truss selects 120 × 60 × 4 galvanizing square tubes, top boom
And web member selects 60 × 40 × 4 galvanizing square tubes, top boom, lower boom and web member prepare truss by way of welding；
Then, according to cornice 1 width, the truss prepared is linked together, two neighboring truss shares a Pin, even
The truss formation unit section connect；According to shape of cornicing, unit section is in in-line or L-shaped, the length of the unit section of in-line
For 2900 ~ 3100mm, preferably 3000mm；The two-way length of the unit section of L-shaped is no more than 1500mm, passes through limiting unit section
Length, so as to facilitate the lifting to unit section and installation.For the quantity of unit section, it is ensured that the length of unit section
Sum is spent at least equal with the width corniced, so that unit section can be in the suspension platform skeleton formed below that cornices.
2. make upper cantilever and be connected the upper cantilever produced with cornicing；
First, length≤3500mm is chosen, the galvanizing square tube of model 120 × 60 × 4 prepares upper cantilever；For
The quantity for the upper cantilever prepared will ensure there is a upper cantilever above every truss structure；Upper cantilever 2, which is encorbelmented, 1 outer end of cornicing
Portion 500mm, so as to avoid because the encorbelment length that of upper cantilever not enough influence the suspension of construction panel.
Then, one external fixer is set per truss structure in the 1 outer end correspondence of cornicing, upper distance of cornicing is corniced outer end
At 2900 ~ 3100mm of portion, preferably 3000mm, correspondence sets two inner fixing devices per truss structure.Wherein external fixer and interior
Fixing device is and the 1 two connected channel-section steels 23 that cornice, lateral separation and the width phase of upper cantilever 2 between two channel-section steels 23
Deng, upper cantilever 2 is located between external fixer and two channel-section steels 23 of inner fixing device, realize upper cantilever 2 and cornice 1 company
Connect.The upper cantilever of setting facilitates the suspension of construction panel, relative to only by construction panel and 1 connection of cornicing, the upper of setting is hanged
Arm can disperse 1 pressure born that cornices, so as to ensure using safety.
3. panel suspension of constructing：
First, prepare suspension rod, intercepted length≤3000mm, the galvanizing square tube of model 120 × 60 × 4 as suspension rod,
Suspension rod is divided into outer suspension rod and interior suspension rod.
Then, at the two ends of suspension rod, two sections of length are respectively welded for 300mm, model 10#The connecting plate 16 of channel-section steel；In weldering
To ensure that the length of connecting plate 16 and the lap of suspension rod is not less than 150mm when connecing, so as to ensure connecting plate and suspension rod
Stable connection.
Finally, the outer end by the connecting plate 16 at the outer two ends of suspension rod 5 respectively with upper cantilever 2 and truss is connected；By interior suspension rod 6
Inner end of the connecting plate 16 at two ends respectively with cornice 1 and truss is connected.When connection, it is ensured that outer suspension rod 5 and interior suspension rod 6
Keep vertical state, and outer suspension rod 5 and interior suspension rod 6 with truss when be connected, and the lower boom of truss frame for connecting.
4. in unit section edge, protection face is set：
First, the middle part of every truss structure 1 is connected with cornicing by steel wire rope 10；
In order to realize the connection corniced with truss, cornicing and flower basket bolt is respectively provided with truss, steel wire rope is arranged in flower
In basket bolt, and fixed by rope cramp 21.After steel wire rope is connected, steel wire rope 10 is tensed using flower basket bolt 22, made
Obtain steel wire rope 10 and be in tensioning state, so that steel wire rope 10 bears pulling force, share the stress of suspension rod, improve the peace of this suspension platform
Quan Xing.
Then, in construction panel end, three level horizontal strokes are passed through between adjacent outer suspension rod and adjacent interior suspension rod
Bar 13 is connected, and the connected mode of wherein horizontal cross bar 13 and suspension rod is：Bolt connection, so that convenient dismounting；Simultaneously in construction surface
At the side of plate, interior suspension rod and outer suspension rod are connected also by three horizontal cross bars.
The distance between three horizontal cross bars and truss surface respectively 500 ~ 700mm, 1100 ~ 1300mm and 1700 ~
1900mm, so that horizontal cross bar fully can set vertical supporting for protection face.
Horizontal cross bar is made using 60 × 40 × 4 hot-galvanized steel square tubes, and its length is the spacing of two outer suspension rods.
Wherein, construction panel end and side are the edges of construction panel, are located at construction panel along the length direction that cornices
Edge for end face；Along cornice width be located at construction face plate edge be side.
Then, steel wire is set on the outside of horizontal cross bar, and steel wire includes protection steel wire rope, in construction panel end
Protection steel wire rope does diagonal drawknot again between two adjacent outer suspension rods or two adjacent interior suspension rods, and is done every two unit sections
One diagonal drawknot, so as to reduce cost；It is diagonal between outer suspension rod and interior suspension rod in the protection steel wire rope of construction panel sides
Drawknot.
Finally, fine mesh vertical net 15 is set between horizontal cross bar and steel wire, and fine mesh vertical net 15 is fixed on iron wire colligation
On steel wire.
