The making of top double flute steel and lower part double flute steel is carried out in material processing site while Bailey truss is set up, on
Portion's double flute steel and lower part double flute steel are made of two same size channel steels, and hole, channel steel and channel steel are reserved between two channel steels
Between using steel cushion block be welded to connect fixation, the steel cushion block of top double flute steel and lower part double flute steel be equipped with it is corresponding can
For the hole that sunpender passes through, after Bailey truss is set up, top double flute steel is hoisted to Bailey truss top, top double flute
It is welded and fixed between steel and Bailey truss top flange；
(3) sunpender is installed,
According to structural stress analysis, the high-strength bolt of appropriate diameter is chosen as sunpender, the length of sunpender is determined according to design
Degree, indicates the installation site of top double flute steel and lower part double flute steel on sunpender, and when installation, sunpender is between the double flute steel of top
Hole on steel cushion block passes through so that top double flute steel is placed in the installation marker location of sunpender, then by nut by sunpender with
Top double flute steel is fixed；
(4) lower part double flute steel is installed,
After the completion of hanger erection, safe steel cat ladder is installed from Bailey truss as easy operation platform, then carries out
Lower part double flute steel is transported to the lower part of Bailey truss by tower crane, using hawser so that sunpender is passed through by the installation of lower part double flute steel
Hole between the double flute steel of lower part on steel cushion block so that lower part double flute steel is placed in the installation marker location of sunpender, then passes through nut
Sunpender and lower part double flute steel are fixed；
(5) it is laid with distribution beam,
After all lower part double flute steel are installed in place, in lower part, the upside of double flute steel is laid with distribution beam；
(6) seating side guard rail,
On distribution beam top, scaffold is set up, and set up and go along with sb. to guard him, all go along with sb. to guard him is closed using Dense mesh screen, and is going along with sb. to guard him
Upper setting anti-drop net；
(7) laydown, template,
Cast-in-situ Beam position, laydown installation form are made in distribution beam.
In step (1), it is 3 meters long, 1.5 meters of height that Bailey truss, which uses 321 beret slices, beret slice sectional dimension,.
In step (2), the steel cushion block is laid along channel steel extending direction and arranges that spacing is 1m~1.5m.
In step (5), distribution beam is made up of the laying of I-steel, and the I-steel is welded and fixed with lower part double flute steel.
In step (6), sets up 1.2 meters high of skirt of facing and protect, steel pipe cat ladder is set up in scaffold, and be laid with step plate, foot
Hand cradle completely spreads bamboo fragrant plant piece, and one of anti-drop net vertically is being arranged every 10 meters as construction operation platform.
The present invention by using Bailey truss hoisting die construction technology solves that landing frame body can not be used due to a varied topography
The case where being.The Bailey truss that hoisting die construction is formed by connecting using beret slice by pin as upper support structure, adopt by substructure
With double flute steel.Up-down structure is attached using high-strength bolt as sunpender by bolt.Finally consolidate using steel plate as baffle plate is hung
It is scheduled on and constitutes stable Bailey truss on channel steel and hang mould support system.It is mainly characterized by reducing that lower support system, progress are fast, throw
Relatively small, guarantee construction quality is provided, is solved well because of the construction difficult problem with a varied topography that can not arrange landing support.Due to group
It is processed in factory floor at the accessory of Bailey truss, dimensional discrepancy very little, and itself has prodigious rigidity, is transported to construction
Scene, which carries out assembling, can become Bailey truss, and length is determined according to cast-in-place beam length.For this purpose, this hoisting die construction method safety
Reliably, easy for construction.
In conclusion the present invention is one can effectively solve that because with a varied topography, height is too high landing support can not be laid
A kind of Bailey truss hoisting die construction method, the present invention adapt to that all are with a varied topography, in large-span structure engineering.
