Description
Technical field
The utility model is related to construction engineering technical fields, more particularly to a kind of special-shaped grout sleeve of bar connecting.
Background technology
In existing prefabricated assembled concrete structural construction field, the side of grout injection in generally use grout sleeve
Formula connects the reinforcing bar of precast concrete.
Grout sleeve is broadly divided into half grout sleeve and full grout sleeve, and one end of half grout sleeve has and bar connecting
Internal thread, the other end of half grout sleeve has the grouting channel of grafting reinforcing bar.Full grouting connector both ends all have grafting steel
The grouting channel of muscle.Grout sleeve relies on the cohesive force and cement mortar and reinforcing bar cross rib of cement mortar and reinforcing bar and sleeve
Reach Bar Anchorage connection effect with the mechanical snap power at sleeve lining cross rib position.In order to provide enough cohesive actions and
Mechanical snap is acted on to prevent reinforcing bar from being extracted from cement slurry, needs the sleeve of enough length sleeves, sufficient amount and height
Inner wall cross rib meets Bar Anchorage connection request.When reinforcing steel bar bear and entrance high-stress state, cement slurry and reinforcing bar and set
The meeting of the bonding progressive failure of cylinder is simultaneously transferred to the power transmitted is bonded in reinforcing bar cross rib and sleeve lining cross rib, reinforcing bar cross rib and set
Cylinder inner wall cross rib subject huge Local bearing capacity, when cross rib negligible amounts, height it is relatively low lead to bearing area deficiency when, meeting
Form the damage -form that cement slurry is extracted with reinforcing bar from grout sleeve.
In the prior art, reinforced bar sleeve can be divided into casting grout sleeve and machining two class of grout sleeve.This two class is in the milk
