With the development of Building technology, the case where vertical structure is constructed prior to horizontal structure, is more and more common, this is related to
To horizontal structure (such as:Floor girder and board) anchorage problem of the beam reinforced steel bar in vertical structure.So far, domestic construction master
Method to be used is that embedded bar method, pre-embedded steel slab welding, template burrow the pre-buried method of joint bar, embedded expansion bolt welding
And the chemical agent bar planting method that burrows.
These methods have certain problem urgently to be resolved hurrily.Embedded bar method after wall column concreting due to that will mix
Solidifying soil, which is chiseled to pick pre-buried reinforcement metal straightening to dig, has the intensity of wall, column certain damage, and it is strong that bending can also influence reinforcing bar
Degree；Pre-embedded steel slab welding on picking for wall column also due to dig the intensity that can also influence wall column, and the quality being welded to connect cannot
Ensure, the application of steel plate can also increase cost；The template pre-buried method of joint bar that burrows has a damage to template, pretty troublesome, application when form removal
Limit to very much；Embedded expansion bolt welding is since welding can influence working bolt performance, and expansion bolt cost is higher；And it burrows
Chemical agent bar planting method special-purpose adhesive higher price, and adhesive brittleness is larger, bearing capacity is relatively low.
