Description
Technical field
The utility model relates to reinforcing steel bar connecting device, in particular to a kind of reinforcing steel bar connecting device and its connection structure.
Background technique
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 be welded to connect, 2) embedded part bolt connection, 3) reinforced bar sleeve be in the milk
Connect three kinds of connection types.
1) built-in fitting welded connecting is that junction steel plate is preset at component connecting portion, 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 is easy to operate；Disadvantage: change because welding procedure reason makes junction steel plate performance that brittleness occur, cause
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 application range is small.
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 in the bolt hole for the pre-embedded steel slab that reserved bolt is inserted into preset component when installing by preset component with nut.Advantage is connection
Intensity is higher than weld strength, disadvantage: at 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 16 and Figure 17, grout sleeve includes sleeve and the installation of both ends open
Stock inlet 101 and grout outlet 102 in sleeve lateral wall.Sleeve is embedded in upper component 103, the embedded ribs of upper component
In 104 insertion sleeves, sleeve stock inlet and grout outlet are reserved in the outside of upper component.When installation, what lower member 105 was protruded
Dowel 106 is inserted into sleeve；After component installation positioning, the seam 107 of upper component and lower member is clogged, then
Grouting material is injected from slurry-feeding hole, makes reinforcing bar in conjunction with sleeve, plays connection function.
Advantage: so that reinforcing bar is in sealed environment and is solved anti-corrosion/durability by grouting after connection reinforcing bar insertion sleeve and ask
Topic, 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. are 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. at 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 it 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 using frictional force principle and effect
Reinforcing bar connection.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 be especially vertical member connection (be 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 there is also one for structure connection in the case where there is no problem for reinforced bar sleeve grouting quality of 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 mortar (the bonding/levelling of member bottom section when vertical prefabricated components installation
Layer) intensity be lower than prefabricated components concrete strength, cause stress point weak, influence the globality poor of concrete structure, antidetonation
The low problem of property.
As shown in figure 18, floor bar 109 can be arranged in the inside of existing precast floor slab 108.Existing one kind in the market
The floor bar 109 of type floor 108 will not expose, i.e., end is concordant；Having the floor bar 109 of a type can expose.The first kind
Floor 108 directly rides upon on girder steel 6 or wall, does not connect between two neighboring floor, so shock resistance is poor.Second class building
Although 108 floor bar 109 of plate can expose, as shown, being only by the dew of floor bar 109 in existing construction technology
Part is connect with post-cast strip concrete out.The floor bar 109 of two pieces of floors 108 is not attached.Therefore, formation is built
It builds node and equally exists the bad problem of shock resistance.
