Description
Technical field
The present invention relates to connecting structure of wall, more particularly to fastening piece type connection binding structure is stretched into outside a kind of sleeve.
Background technology
Currently, prefabricated concrete structure is built, the connection method of prefabricated components, especially vertical member（Prefabricated panel/
Column）Vertical bar connection mode mainly have：1）Built-in fitting is welded to connect, 2）Embedded part bolt connection, 3）Reinforced bar sleeve is in the milk
Connect three kinds of connection types.
1）It is that junction steel plate is preset at component connecting portion that built-in fitting, which is welded to connect, after prefabricated components installation is just, by structure
Adjacent pre-embedded steel slab is welded to connect integral mode and connects between part.
Advantage：Installation operation is simple；Disadvantage:Change because welding procedure reason makes junction steel plate performance that brittleness occur, causes
Steel plate poor toughness/easy to crack/bonding strength is low, structure connection integrity/air-tightness/shock resistance is poor, anti-corrosion/durability is poor；It is existing
Belonging to filtering technique, market is small using application range.
2）Embedded part bolt connection method is to reserve installation bolt by pre-embedded steel slab prepared screw-bolt hole, and in installation position,
It is fastened with nut in the bolt hole for the pre-embedded steel slab that reserved bolt is inserted into preset component when preset component installation.Advantage is connection
Intensity is higher than weld strength, disadvantage：It is of high cost, structure connection integrity/air-tightness/shock resistance is poor, anti-corrosion/durability is poor；City
Field application range is small.
3）Reinforced bar sleeve grouting connection：As shown in Figure 17 and Figure 18, grout sleeve includes sleeve and the installation of both ends open
Stock inlet 1031 in sleeve lateral wall and grout outlet 1032.Sleeve is embedded in upper component 1033, upper component it is pre-buried
In 1034 insertion sleeve of muscle, sleeve stock inlet and grout outlet are reserved in the outside of upper component.When installation, lower member 1035 is convex
In 1036 insertion sleeve of dowel gone out；After component installation positioning, the seam 1037 of upper component and lower member is filled out
Then plug injects grouting material from slurry-feeding hole, so that reinforcing bar is combined with sleeve, play connection function.
Advantage：Reinforcing bar is set to be solved in sealed environment by grouting after connection reinforcing bar insertion sleeve
Anti-corrosion/endurance issues, bonding strength are better than the above two ways welded and bolt.
Disadvantage：In practical application, reinforced bar sleeve grouting interconnection technique has the following problems to need to improve：1. being become by reinforcing bar
Gap is small etc. that factors influence constructing operation difficulty is big for shape, displacement, installation；2. spillage problem is easy to happen and can not quality inspection；3. behaviour
Make complex process, needs special equipment, tool, material, personnel；4. of high cost, quality is difficult to control；4. influencing grouting material quality
Factor it is more（Material, the ratio of mud, stirring, slip casting, spillage, personnel's operation, application time etc.）, quality control difficulty is big；5. by
It is to be bonded reinforcing bar and sleeve by grouting material in reinforced bar sleeve grouting interconnection technique, is realized with effect using frictional force principle
Bar connecting.So grouting material as connection medium, play the decisive role of quality of connection, it is necessary to be in the milk it is full, without leakage
Slurry, ungauged regions still, in actual application are especially vertical member connection（It is easy spillage and can not quality inspection）It is difficult to ensure that
Quality of connection, quality controllability are poor；The quality of quality of connection directly affects the bonding strength of reinforcing bar, forms invalid connection（Reinforcing bar
Core pulling phenomenon）, cause building safety hidden danger.
In addition, even if in the case where there is no problem for reinforced bar sleeve grouting quality of connection, there is also one for structure connection
Insurmountable technical problem：Vertical concrete prefabricated element structure connection integrity problem, that is, prefabricated components bottom with
Problem is stitched in the horizontal connection of the cast-in-place interlayer of superimposed sheet.Because of the mortar of member bottom section when vertical prefabricated components installation（Bonding/levelling
Layer）Intensity causes stress point weak, influences the globality poor of concrete structure, antidetonation with less than prefabricated components concrete strength
The low problem of property.
