Detailed description of the invention
Below in conjunction with a kind of large diameter steel pipe suspension column construction method that has adopted the utility model structure and accompanying drawing, the utility model is described in further detail.
When concrete enforcement: a kind of Large-diameter Steel tubing string suspension column construction that has adopted the utility model structure, comprises the following steps:
A, after foundation ditch acceptance(check), in foundation ditch, pour into a mould the base concrete bed course of C30;
B, above foundation ditch bed course colligation bottom reinforcement bars net sheet and sidewall reinforced mesh;
C, four crab-bolts of installation;
Above-mentioned steps a and step b self are ripe prior art, do not describe in detail at this, and the method is made the place of improving and contributing to prior art, be:
Described crab-bolt is M36 crab-bolt, crab-bolt adopts pre-buried location ring flat-plate to position while installation, and the vertical rod stent support of the pre-buried front employing steel tubular structure of location ring flat-plate positions installation, and described location ring flat-plate adopts width 100mm, the doughnut-shaped steel plate of thickness 10mm, to guarantee crab-bolt installation accuracy; On doughnut-shaped steel plate, be provided with four crab-bolt installing holes along orthogonal two diametric(al)s.Time prepared by doughnut-shaped steel plate, first setting-out blanking, afterwards according to first unwrapping wire on steel plate strip (being doughnut-shaped steel plate) of the relative position of crab-bolt, find out the relative position (both relative positions of every post crab-bolt) of anchor hole, then be placed on platen hole (being crab-bolt installing hole), the diameter in hole, than the large 1mm of crab-bolt diameter, is beneficial to crab-bolt and installs.
Wherein, the concrete steps of pre-buried location ring flat-plate comprise: crab-bolt is installed front on foundation ditch bed course, adopt total powerstation unwrapping wire (drawing criss-cross basic axis), first determine four crab-bolt positions according to drawing, four points that then intersect along the tangent line of place circle four crab-bolts are defined as vertical rod installation site; When colligation bottom reinforcement bars net sheet, avoid vertical rod installation site, and bore the fixing hole of φ 16mm and dark 20mm downwards four vertical rod installation sites, adopt the fixing reinforcing bar of φ 16mm squeeze into straight down in fixing hole and leave the welding section protruding upward outside fixing hole, on the welding section of fixing reinforcing bar top, be welded and fixed straight up the vertical rod of tube material; After vertical rod is fixing, first penetrate three-layer network sheet muscle (reinforced mesh), then first adopt steel tube fastener to connect in vertical rod upper end two 1# supporting steel pipe and 2# supporting steel pipes that level is relative are set, adjust 1# supporting steel pipe and 2# supporting steel pipe planeness and highly make its upper surface for direct supporting and location ring flat-plate by Mobile steel tube clamps, two layers of mesh sheet muscle (penetrating go up most two layers of three-layer network sheet muscle) in colligation below 1# supporting steel pipe and 2# supporting steel pipe again, upper two layers of mesh sheet muscle is by fixed to 1# supporting steel pipe and 2# supporting steel pipe and four vertical rods; Two levels are set relatively and 3# supporting steel pipe and the 4# supporting steel pipe vertical with 1# supporting steel pipe by connecting in the vertical rod of steel tube fastener below upper two layers of mesh sheet muscle again, after then colligation three-layer network sheet muscle (basecoat of the three-layer network sheet muscle penetrating) makes 3# supporting steel pipe and 4# supporting steel pipe and vertical rod fixed; Then doughnut-shaped steel plate is supported and is arranged on 1# supporting steel pipe and 2# supporting steel pipe upper surface, and make four crab-bolt installing holes on doughnut-shaped steel plate and four crab-bolt position consistency (before and after welding, carry out position measurement check guarantee crab-bolt position of mounting hole and place top surface plane positional precision accurate), to between doughnut-shaped steel plate and 1# supporting steel pipe and 2# supporting steel pipe, be welded and fixed, simultaneously by the reinforcing bar of vertical diameter 20mm, doughnut-shaped steel plate and 3# supporting steel pipe and 4# supporting steel pipe are welded and fixed; Then in the crab-bolt installing hole of doughnut-shaped steel plate, install crab-bolt, check after crab-bolt positioning precision meets code requirement and complete suspension column bottom concreting, construction that steel pipe column lifting is fixed and be in the milk in suspension column bottom.
