Abstract
The joining method includes anchoring the longitudinal stressed reinforcing bars and structural reinforcing bars with bonding agent at the lateral side of the original foundation (original bearing platform) and installing an anchor-bar type bearing platform to join the original foundation and underpinnings. Advantage: no influence on the building and worker's safety, good construction quality, low construction cost, and wide application range.
Description
The present invention relates to the reinforcing of building foundation.
For the pile foundation or the excessive sedimentation of single footing generation of control built construction thing, often adopt the pile underpinning mode that the basis is reinforced.In pile underpinning, need to adopt certain method of attachment that original structure and underpinned pile are coupled together, the part-structure load is delivered on the underpinned pile reliably.More general method of attachment at present is bag pillar cushion cap method of attachment and the method for attachment of bottom-supported type cushion cap.The method of attachment of bag pillar cushion cap is the new cushion cap of casting a parcel pillar and extend to the underpinned pile top on former basis (former cushion cap), the part-structure load is delivered on the underpinned pile by new cushion cap, it is many that this method consumes material, and be only limited to former basis (former cushion cap) apart from the enough situations of ground level.The method of attachment of bottom-supported type cushion cap is that (former cushion cap) casts the new cushion cap being close to bottom, former basis (former cushion cap) and extending to the underpinned pile top below the bottom surface on former basis, the part-structure load is passed on the underpinned pile by new cushion cap, and this method cutting depth is big, construction is dangerous, quality be cannot say for sure card, construction costs height.
The objective of the invention is for pile underpinning provides a kind of construction safety, saves material, quality is easy to guarantee, cushion cap method of attachment applied widely.
Technical program of the present invention lies in: (former cushion cap) side sticks with glue agent anchoring longitudinal stress reinforcing bar and distributing bar on former basis, anchor-rod type supporting table is set connects former basis (former cushion cap) and underpinned pile.
The invention has the advantages that: construction period does not influence building and constructor's safety, and construction quality guarantees that easily construction costs is low, and the scope of application is extensive.
Further specify the operation of operating principle of the present invention and enforcement below by accompanying drawing.
Accompanying drawing 1 structure principle chart.
The K of accompanying drawing 2 accompanying drawings 1 is to view.
Among the figure: post 1, former basis (former cushion cap) 2, former stake 3, underpinned pile 4, concrete 5, longitudinal stress reinforcing bar 6, distributing bar 7, distribution reinforcement 8, new and old concrete interface 9.
Operating principle of the present invention is: the entire infrastructure load acts on former basic 2 by post 1, wherein fractional load is by the tension effect of longitudinal stress reinforcing bar 6, the pressurized effect at new and old concrete interface 9 and the effect of being cut are delivered to new cushion cap (anchor-rod type supporting table), longitudinal stress reinforcing bar 6 had both worked to be subjected to curved main muscle, work to suppress new and old concrete interface 9 crackings again, guarantee the continuity at new and old concrete interface, thereby anchor-rod type supporting table can bear and resist the moment of flexure that produces because of load action, scissors and flush shear force, and with Load Transfer to underpinned pile 4.
Enforcement operation of the present invention is as follows: the former basic side earthwork of excavation earlier, cut underpinned pile 4 pile crowns, and bore anchor hole, bury underground and anchoring longitudinal stress reinforcing bar 6 and distributing bar 7, cutter hair concrete interface 9, colligation distribution reinforcement 8, the 9 batches of cement pastes in concrete interface water and smash concrete, maintenance.
In practice of construction, former basis can sublevel or sublevel not; Former stake and underpinned pile can be various types of stakes (then not having former stake if former basis is the single footing); Anchor-rod type supporting table can all be connected with former basis at two ends, but in this case, anchoring longitudinal stress reinforcing bar should place top, and the anchoring structure reinforcing bar should place the bottom.
Claims (1)
1, a kind of method for connecting anchor-rod type supporting table is characterized in that: stick with glue agent anchoring longitudinal stress reinforcing bar and distributing bar in former basis (former cushion cap) side, anchor-rod type supporting table is set connects former basis (former cushion cap) and underpinned pile.
