Description
Technical field
The present invention relates to the realm of building construction, more particularly to a kind of anchor structure and construction method.
Background technology
Traditional locks setting formula typically uses post stretching as shown in Figure 3, then carries out the reserved sleeve pipe of Bo plates foundation construction, treats Bo plates
After the completion of basis tensioning fixation is carried out to reserving the anchor pole in sleeve pipe.Concrete technology following 1）Cut former concrete face；2）Anchor plate, anchor
Muscle is welded with former raft plate；3）Post-stretching is carried out to anti-float anchor rod；4）Rock bolt, its advantage is can to ensure that single anchor rod is locked
Determine power.There is problem:Anchor hole is reserved in raft plate cannot be in the milk, and water produces corrosion to anchor pole in hole, influences its durability, increases
Plus plank thickness, the existing raft plate waterproof of destruction, therefore following shortcoming 1 can be brought）Larger is influenceed on operation, influence Bo plates basis steel
Muscle colligation；2）Waterproofing node intractability increases, and needs to carry out water-proofing treatment between Bo plates and sleeve pipe, locking rear sleeve need to pole stock it
Between water-proofing treatment；3）Keyed end durability cannot ensure；4）There is larger man's activity in technological operation；5）Material is cumbersome, is difficult
Control（Construction is combined using multiple material）.Therefore the application designs a kind of its matching operation method of new anchor structure.
The content of the invention
In order to solve above-mentioned problem, the present invention provides a kind of anchor structure and construction method, using built-in type, applies
Work process is constructed with Bo plates basic synchronization, and the same period pours, and with Bo slab muscle synchronous constructions, does not produce influence on operation, changes it
Construction node that is preceding complicated and should not controlling, reduces artificial construction error, is that, up to this purpose, the present invention provides a kind of anchoring knot
Pre-buried steel sleeve, anti-float anchor rod, prestress steel in structure, including pre-buried sealing off and covering anchorage pressure grouting pipe, supporting anchorage, anchor plate, base plate
Twisted wire and spiral reinforcement, the anti-float anchor rod are repaired below bed course in concrete grouting, and pre-buried steel sleeve is existing in the base plate
Sole plate top and concrete grouting are repaired between bed course, there is a pair of prestress wires in the base plate in pre-buried steel sleeve
With a pre-buried sealing off and covering anchorage pressure grouting pipe, pre-buried steel sleeve upper end has anchor plate in the base plate, and the anchor plate is on existing basis
On base plate top, the prestress wire upper end passes through anchor plate, there is supporting anchorage, the supporting anchorage on the anchor plate
Upper matcoveredn, the prestress wire upper end passes through anchor plate, the pre-buried sealing off and covering anchorage pressure grouting pipe to pass protective layer, institute
Stating existing sole plate top lower section has spiral reinforcement, and the spiral reinforcement is sleeved on pre-buried steel sleeve upper end in base plate.
Further improvement of the present invention, the prestress wire upper end is fixed by intermediate plate, sets intermediate plate control steel and twists
The connection of line and anchorage.
Further improvement of the present invention, pre-buried steel sleeve overcoat has outer seal ring in the base plate, pre-buried in the base plate
There is interior seal ring in steel sleeve, interior seal ring is that the seal ring inside service sleeve is added in above prestress wire or reinforcing bar
, prevent underground water from being creeped up by pole stock, the seal ring of outside is placed on outside service sleeve, the water for preventing base plate
Prolong service sleeve to creep up.
A kind of anchor structure construction method of the present invention, comprises the following steps that：
1）Any destruction is not being carried out to original construction raft plate, anchor plate is being installed at the top of anti-float anchor rod；
2）Supporting anchorage is installed on anchor plate；
3）By the supporting anchorage of stretching method tensioning fixation；
4）By pre-buried sealing off and covering anchorage pressure grouting pipe in pre-buried steel sleeve in base plate reserving hole channel in raft plate is carried out pressure recharge without
Shrinkage grouting filler；
5）Repair anchorage node raised, complete construction.
Further improvement of the present invention, step 5 is repaired anchorage node projection and is repaired using mortar, and reparation is mainly adopted
Use mortar.
A kind of anchor structure of the present invention and construction method, the new anchor type use built-in type, can be with Bo plates basis
Synchronous construction, the same period pours, and due to itself and Bo slab muscle synchronous constructions, does not produce influence on operation, anti-in sole plate construction
Increase the body of rod waterproofing node after water, water-swellable waterstop can effectively fill concrete and space, the application locking section are connected with the body of rod
Point is placed in Bo plates, is had a style of one's own with Bo plate cage bars, and optimizes bottom slab stress, and single anchor rod increases stirrup and Bo plates are matched somebody with somebody
Muscle is encrypted, and reduces concentrated stress, and whole construction uses assembled material, so that complicated before changing and applying of should not controlling
Work node, can integrally customize, and reduce artificial construction error.
