Abstract
The invention discloses a method for padding of a split bolt hole of a concrete shear wall. According to the method for padding of the split bolt hole of the concrete shear wall, a traditional uniform-section split bolt is replaced by a variable-section split bolt sleeve when a shear wall formwork is reinforced. The method for padding of the split bolt hole of the concrete shear wall comprises the following steps that the split bolt hole is formed in the concrete shear wall, a variable-section circular truncated cone rubber plug is placed and stuffed in the split bolt hole from the inner side of the concrete shear wall, a polyurethane foaming material which has the air hardening performance, resists seepage and preserves heat is injected into the split bolt hole, and an inner portion with the length of 15mm of the split bolt hole and an outer portion with the length of 15mm of the split bolt hole are reserved and padded with expanded mortar. According to the method for padding of the split bolt hole of the concrete shear wall, full-hole padding is guaranteed and padding is dense; the polyurethane foaming material which has the air hardening performance, resists seepage and preserves heat is used for padding, so that the padding quality is improved, and the seepage-proof and heat-preservation effect is good.
Description
Technical field
The present invention, for builing industry, is specifically related to the filling method in a kind of concrete shear force wall split bolt hole.
Background technology
The essential hole arranging when concrete shear force wall split bolt hole is concrete shear force wall formwork reinforcement, for the filling of concrete shear force wall split bolt hole, adopts the filling of expansion expansive mortar conventionally.Traditional split bolt hole, can not once clog, and filling need be clogged several times, not only will be in inboard to plug, but also to stop up in outside.Outside need to utilize outrigger while stopping up, and constructs very inconvenient, also dangerous.Traditional split bolt hole filling, adopts filling on one side, Yi Bian plug and pound, for this filling method, owing to restricted by operating personnel's accountability, probably cause two ends filling, middle empty phenomenon, can not guarantee the filling of full hole, make to clog leakiness, filling effect is lower, filling effect is undesirable, finally cause exterior wall leakage, heat insulation effect is bad, at this position, forms cold bridge.
Summary of the invention
For solving the technical problem of above-mentioned existence, the invention provides the filling method in a kind of concrete shear force wall split bolt hole, shear wall formwork adopts variable cross-section Split bolt sleeve while reinforcing, substitute traditional uniform section Split bolt sleeve, Split bolt sleeve can adopt PVC, UPVC, aluminium-plastic pipe or steel variable cross-section sleeve pipe.
The technical scheme that the present invention proposes is: the filling method in a kind of concrete shear force wall split bolt hole, and its concrete step is:
1) on concrete shear force wall, form split bolt hole: after shear force wall reinforcing steel bar colligation is good, shear wall formwork is installed, is placed variable cross-section Split bolt sleeve and split bolt bar, by split bolt compression device, template is reinforced, after formwork reinforcement is good, build shear wall concrete, after concrete setting, and not during sticking to mould, loosening split bolt, take out split bolt, stripping, just there is variable cross-section split bolt hole in concrete shear force wall;
2) place rubber stopper: adopt variable cross-section round platform post rubber stopper, from shear wall inboard, fill in split bolt hole, rubber stopper is shifted onto apart from 15 mm prescriptions of wall outer side surface layer and can be stopped, and this rubber stopper is as the external mold that injects anti-seepage heat preservation material;
3) filling split bolt hole: to the rigid anti-seepage heat preservation polyurethane foam material of injected gas in split bolt hole, injection polyurethane foam material can stop apart from shear wall inner surface 15 mm in the hole in;
4) filling both sides, split bolt hole: all reserved 15 mm places inside and outside adopting expansive mortar filling split bolt hole.
Make variable cross-section split bolt hole sleeve, Split bolt sleeve length is generally 200mm, 250mm, 300mm, 350mm, casing inner diameter: one end diameter is 30 mm, and the other end is 35mm, and steel sleeve wall thickness is 1mm, and other material wall thickness is 2.5 mm.
By the round table-like rubber stopper of variable cross-section, from the inboard plug of shear wall rubber stopper, be that one end diameter of section is 33 mm, other end diameter of section is 35 mm, and rubber stopper length is 30mm.
The invention has the beneficial effects as follows: the method is a kind of Novel seepage, is incubated efficient consent filling method, guarantee the filling of full hole, make to clog closely knit, adopt the polyurethane material of anti-seepage heat preservation to fill, improve filling quality, anti-seepage heat preservation is respond well.
