Wherein, the set-up mode of unloading wire rope is, per pass Cantilever Beams establishes 6 × 19(a together), Φ 17.5 steel wire rope unloading; For the position using shaped steel tripod, 6 × 19(a is together added to shaped steel tripod), Φ 17.5 unloads wire rope, between unloading wire rope and tripod, angle is 45 ° ~ 60 °, and structure rotation angle position uses 6 × 19(a) Φ 17.5 wire rope pocket vertical rod node unloads support body, and wire rope pocket is hung on support body host node, the each host node of horizontal plane arranges together, saddle clip 8 joined by every root wire rope, 6 for firm, 2 for arrange safety curved.
The construction technology process of section steel tripod support body is:
1 cast-in fixing bolt → 2 section steel tripod is installed → 3 channel-section steels and is installed little cross bar → 12 repetition of → 4 horizontal second step leger → 11, the first step little cross bar → 10, first step leger → 9, bar → 8 second step of sweeping the floor in longitudinal vertical rod → 7, bar → 6 of sweeping the floor 10,11 steps to bridging → 15, wall-connecting piece → 14, design height → 13 scaffold floor, flak jacket hurdle, foot guard plate → 16 safety net.
The construction technology of profile steel overhanging steel pipe scaffold system is:
1), built-in fitting construction: girder steel anchor ring to be constructed pre-plugged with roof steel bar, and use HPB235 Ф 18 reinforcement fabrication, the return certain distance of girder steel anchored end end arranges first girder steel anchor ring, and girder steel wing plate welds vertical rod antiskid bar;
2), cantilever steel girder is installed: cantilever steel girder entirety uses i iron, is evenly arranged by constant spacing, meets frame column, wall, ater-casting cannot even cloth position, the frame column that staggers, wall, arrange cantilever steel girder apart from post, wall limit 100mm; Cantilever steel girder meets shear wall structure position, before body of wall is built in relevant position high × wide preformed hole for 220mm × 120mm of indwelling in advance;
3), shaped steel tripod is installed: section steel tripod uses 14# i iron and 10# i iron to be welded, and uses anchor and high-strength chemical bolt and body of wall to connect;
4), vertical rod installs: vertical rod up and down on a vertical line, when vertical rod adopts docking spreading, vertical rod interlaced arrangement is answered to clasp, the joint of two adjacent vertical rods be not arranged on synchronous in;
5), leger is installed: connected with vertical rod cruciform fastening for falsework by adjacent leger from 200mm anti-on bottom of upright rod, the joint location of upper and lower cross bar is staggeredly arranged in different vertical rod advances;
6), little cross bar is installed: outside removing host node, the leger of two longitudinal host nodes adds little cross bar together, little cross bar to the length chosen between 40mm ~ 50mm, arrange near vertical rod, host node place must arrange a little cross bar, with being fixed in vertical rod with the little cross bar right-angle coupler socketed, the center to center distance of two right-angle couplers in host node place should not be greater than 150mm;
7), wall-connecting piece is installed: vertical interval is two steps, level interval be three across, wall-connecting piece arranges to order anyhow, be evenly arranged, vertical with structural facades with support body, the one end be connected with support body allows declivity slightly, must not upwarp, wall-connecting piece is not more than 300mm apart from the distance of host node, and the length that wall connecting rod stretches out fastener should be greater than 100mm;
8), steel wire rope unloading:
Per pass Cantilever Beams establishes 6 × 19(a together), Φ 17.5 steel wire rope unloading; For the position using shaped steel tripod, 6 × 19(a is together added to shaped steel tripod), Φ 17.5 unloads wire rope, between unloading wire rope and tripod, angle is 45 ° ~ 60 °, and structure rotation angle position uses 6 × 19(a) Φ 17.5 wire rope pocket vertical rod node unloads support body, and wire rope pocket is hung on support body host node, the each host node of horizontal plane arranges together, saddle clip 8 joined by every root wire rope, 6 for firm, 2 for arrange safety curved;
9), support body is checked and accepted
When structure reinforcing bars colligation examination, model sheetinstallat complete and complete with concreting, all burying underground of the built-in fittings such as anchor ring is carried out an acceptance inspection, wherein girder steel location examination time, answer close inspection girder steel encorbelment and whether anchorage length meets specification and designing requirement, check that whether the position of hole to be provided is accurate, check that whether the welding of girder steel suspension ring and vertical rod antiskid bar firm, and after often having set up one wall-connecting piece, tackle support body once check and accept, check and accept by after can continue to set up.
Wherein most wall-connecting piece takes thick pillar form, meets post position and arranges together, according to wall-connecting piece two step three across design adopt following measures to ensure the construction of wall-connecting piece:
(1) in beam, bury short steel pipes underground, depth of burying 200mm, expose 100mm, use Ф 48.3 × 3.6 steel pipe, cruciform fastening for falsework are rigidly connected to support body and structure, and wall-connecting piece uses two fastener;
(2) meeting shear wall position uses Ф 25 reinforcing bar to weld with short steel pipes or little cross bar, and utilize shear wall through-wall bolt hole, passed in the air by Ф 25 reinforcing bar from through-wall bolt, screw rod both sides add 100 × 100 × 8 iron plate pads, and both sides use double nut to tighten.
Points for attention for section steel tripod is installed:
Section steel tripod uses 14# i iron and 10# i iron to be welded, and uses anchor and high-strength chemical bolt and wall connecting.Tripod must be agreed to through design before installing, and is veritified structural bearing capacity by design.Due to support body construct time, initial layer structure frame column has been constructed complete, therefore, anchor needs the accurate unwrapping wire of anchorage point before installing, to stagger reinforcing bar encrypted area, so that bolt is planted in punching, and each connector center of anchoring spiral shell to the distance of nearest host node should be carried out in advance be not more than 1/3 of advance.
Points for attention for wall-connecting piece is installed:
Meeting shear wall position uses Ф 25 reinforcing bar to weld with short steel pipes or little cross bar, and utilize shear wall through-wall bolt hole, passed in the air by Ф 25 reinforcing bar from through-wall bolt, screw rod both sides add 100 × 100 × 8 iron plate pads, and both sides use double nut to tighten; Wall-connecting piece arranges to order anyhow, be evenly arranged, vertical with structural facades with support body, the one end be connected with support body can declivity slightly, must not upwarp; Wall-connecting piece is as far as possible near host node (distance apart from host node is not more than 300mm).The length that wall connecting rod stretches out fastener should be greater than 100mm.
Points for attention for steel wire rope unloading:
Use the position of section steel tripod, 6 × 19(a together added to section steel tripod), Φ 17.5 steel wire rope unloading, between unloading wire rope and tripod, angle is 45 ° ~ 60 °.Girder steel wing tip welding Φ 32 antiskid bar; On 8 layers, structure, border, 29.4m place arranges wire rope and unloads scaffold support body, and wire rope level interval is that 3m(draws a layout every one).6 × 19 Ф 12.5 wire rope selected by unloading wire rope, adopt the connected mode of embracing beam, utilize structure coupling beam to wear beam bolt hole or reserve Chuan Liang hole in unloading relevant position, wire rope place.
As shown in Figure 6: structure is delivered position and carried out reinforcement design, uses 6 × 19(a) Φ 17.5 wire rope pocket vertical rod node unloads support body, and wire rope pocket is hung on support body host node, and each host node of horizontal plane is arranged together.Saddle clip 8 joined by every root wire rope, 6 for firm, 2 for arranging " safety curved ".
