The construction technology process of shaped steel tripod support body is:
1 cast-in fixing bolt → 2 shaped steel tripods is installed → 3 channel-section steels and → 4 bar → 8 first step legers → little cross bar of 9 first steps → 10 second step legers → little cross bar of 11 second steps → 12 of laterally sweeping the floor, bar → 6 vertical rods → 7 of vertically sweeping the floor are installed are repeated 10,11 steps to design height → 13 wall-connecting pieces → 14 bridgings → 15 scaffold floors, flak jacket hurdle, foot guard plate → 16 safety nets.
The construction technology of shaped steel overhanging type steel pin hand frame system is:
1), built-in fitting construction: the girder steel anchor ring is buried underground in advance with the top board reinforcement construction, uses HPB235 Ф 18 reinforcement fabrications, and the terminal return certain distance of girder steel anchored end arranges the first road girder steel anchor ring, at girder steel wing plate welding vertical rod antiskid bar;
2), cantilever steel girder is installed: cantilever steel girder integral body is used i iron, evenly arranges by constant spacing, and the cloth position can't be spared in chance frame column, wall, ater-casting, and the frame column that staggers, wall are arranged cantilever steel girder apart from post, wall limit 100mm; Cantilever steel girder is met the shear wall structure position, keeps somewhere height * wide in the relevant position in advance and be the preformed hole of 220mm * 120mm before body of wall is built;
3), the shaped steel tripod is installed: the shaped 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 the butt joint spreading is adopted in vertical rod, vertical rod clasp is answered interlaced arrangement, in the joint of two adjacent vertical rods is not arranged on synchronously;
5), leger is installed: go up anti-200mm from the vertical rod bottom and begin adjacent leger and vertical rod are joined with cruciform fastening for falsework, the joint location of upper and lower cross bar is staggeredly arranged in different vertical rod advances;
6), little cross bar is installed: remove outside the host node, leger at two vertical host nodes adds little cross bar together, little cross bar to the length of choosing between 40mm～50mm, arrange near vertical rod, the host node place must arrange a little cross bar, with being fixed in the vertical rod with right-angle coupler with the little cross bar that sockets, the center to center distance of two right-angle couplers in host node place should be greater than 150mm;
7), wall-connecting piece is installed: vertical interval was two steps, level interval is three to stride, wall-connecting piece is anyhow to order arrangement, even layout, vertical with the structure facade with support body, an end that is 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 wall connecting rod stretches out the length of fastener should be greater than 100mm;
8), wire rope unloading:
The per pass beam of encorbelmenting establishes together 6 * 19(a), the unloading of Φ 17.5 wire rope; For the position of using the shaped steel tripod, the shaped steel tripod is added one 6 * 19(a), Φ 17.5 unloading wire rope, angle is 45 °～60 ° between unloading wire rope and the tripod, and the structure rotation angle position uses 6 * 19(a) Φ, 17.5 wire rope pocket vertical rod nodes that support body is unloaded, and the wire rope pocket is hung on the support body host node, each host node setting of horizontal plane together, every wire rope is joined 8 of saddle clips, and 6 are used for firmly, and 2 to be used for that safety is set curved;
9), support body is checked and accepted
When structure reinforcing bars colligation examination, template installation and concreting are finished, all burying underground of built-in fittings such as anchor ring carried out an acceptance inspection, wherein during the examination of girder steel location, answer the close inspection girder steel encorbelment and whether anchorage length meets standard and designing requirement, whether the position that checks hole to be provided is accurate, whether the welding that checks girder steel suspension ring and vertical rod antiskid bar firm, and the reply support body is is once checked and accepted after whenever having set up one wall-connecting piece, examination by after can continue to set up.
Wherein most wall-connecting pieces are taked the thick pillar form, meet the post position and arrange together, adopt following measures to guarantee the construction of wall-connecting piece according to the design that two steps three of wall-connecting piece stride:
(1) bury short steel pipes underground in beam, depth of burying 200mm exposes 100mm, uses Ф 48.3 * 3.6 steel pipes, cruciform fastening for falsework that support body and structure are rigidly connected, and wall-connecting piece uses two fasteners;
(2) meet the shear wall position and use Ф 25 reinforcing bars and short steel pipes or the welding of little cross bar, utilize shear wall through-wall bolt hole, Ф 25 reinforcing bars are passed in the air from through-wall bolt, the screw rod both sides add 100 * 100 * 8 iron plate pads, and both sides use double nut to tighten.
Points for attention for the installation of shaped steel tripod:
The shaped steel tripod uses 14# i iron and 10# i iron to be welded, and uses anchor to be connected with body of wall with high-strength chemical bolt.Must agree through design before tripod is installed, by design structural bearing capacity be veritified.Because during the support body construction, first floor structural frames trestle has been constructed and has been finished, therefore, before installing, anchor needs the accurate unwrapping wire of anchorage point, the reinforcing bar encrypted area that staggers so that bolt is planted in punching, and should be carried out each joint center of anchoring spiral shell to the distance of host node recently in advance and is not more than 1/3 of advance.
Points for attention for the wall-connecting piece installation:
Meet the shear wall position and use Ф 25 reinforcing bars and short steel pipes or the welding of little cross bar, utilize shear wall through-wall bolt hole, Ф 25 reinforcing bars are passed in the air from through-wall bolt, the screw rod both sides add 100 * 100 * 8 iron plate pads, and both sides use double nut to tighten; To order arrangement, even layout, vertical with the structure facade with support body, an end that is connected with support body is declivity slightly, must not upwarp anyhow for wall-connecting piece; Wall-connecting piece is as far as possible near host node (distance apart from host node is not more than 300mm).Wall connecting rod stretches out the length of fastener should be greater than 100mm.
Points for attention for the wire rope unloading:
Use the position of shaped steel tripod, the shaped steel tripod is added one 6 * 19(a), the unloading of Φ 17.5 wire rope, angle is 45 °～60 ° between unloading wire rope and the tripod.Girder steel wing tip welding Φ 32 antiskid bars; On 8 layers on structure, border, 29.4m place arranges wire rope the scaffold support body is unloaded, and the wire rope level interval is that 3m(draws a layout every one).The unloading wire rope is selected 6 * 19 Ф, 12.5 wire rope for use, adopt to embrace the connected mode of beam, utilizes the structure coupling beam to wear the beam bolt hole or reserves the Chuan Liang hole in unloading relevant position, wire rope place.
As shown in Figure 6: structure is delivered the position and is strengthened design, uses 6 * 19(a) Φ, 17.5 wire rope pocket vertical rod nodes that support body is unloaded, and the wire rope pocket is hung on the support body host node, and each host node setting of horizontal plane together.Every wire rope is joined 8 of saddle clips, and 6 are used for firmly, and 2 are used for arranging " safety is curved ".
