Description
Technical field
The utility model belongs to field of engineering building, and in particular to grout sleeve reinforcement location fixator.
Background technology
Country carries forward vigorously building industrialization, and country strives that is to say 2025 with 10 years or so time, and assembled is made to build
It builds and accounts for the ratio of new building and reach 30%.The connection of assembled architecture is key technology, and half grouting interconnection technique is with most
For one of extensive interconnection technique, half grouting connection be typically upper end bar using straight thread, lower end bar by grouting material with
Grout sleeve is attached.It is generally used for precast shear wall, the connection of frame column main reinforcement.Sleeve grouting material is with cement for basic material
Material is equipped with the dry blend of fine aggregate and concrete admixture and other materials composition, has good flowing after adding water to stir
Property, the performances such as early strong, high-strength, microdilatancy, the dry mash being filled in sleeve and Ribbed Bar gap, referred to as " sleeve is in the milk
Material ".
It ensures that the connection of reinforcing bar and sleeve is reliable, need to ensure the bond stress between reinforcing bar and sleeve, ensure that bond stress has two
A key governing factor one reinforcing bar is hit exactly in sleeve, the second is the grouting in sleeve is full.Reinforcing bar is in the position of sleeve at present
It is concealed work, detection difficulty is big, and amount detection is more, and effect is again very crucial, and detection grout sleeve construction quality mainly has super
Acoustic wave detection, X-ray detection method and temperature detection method, but be all to detect the above problem from detection level, from sleeve and
It is improved with reinforcing bar sheet.The patent is hit exactly from the structurally guarantee reinforcing bar of sleeve and reinforcing bar in sleeve, is passed by the way that pressure is arranged
Sensor detects the full degree of mortar at bed joint of reinforcing bar in sleeve, can greatly ensure the quality of connection of grout sleeve, can build the life-cycle
The quality of cycle monitoring grout sleeve, to estimate the reliability of building.
The fixed device of grout sleeve reinforcement location, reinforcing bar is not utilized to be inserted directly into grout sleeve in grout sleeve at present
Whether operator checks reinforcing bar in grout sleeve center by minute surface.Since component quality is huge, the connection reinforcing bar of component needs
Centering quantity is more, big for the pinned task amount of grout sleeve reinforcing bar, the heavy workload of operator；Simultaneously because not attached
The guarantee of part, every bar connecting need to check with minute surface, heavy workload.If being unsatisfactory for requiring, reinforcement location need to be adjusted, still
The difficulty of concealed work, detection increases, and requires the professional personal integrity of operator very high.Using grout sleeve reinforcement location fixator
It can ensure that reinforcing bar is hit exactly in sleeve, reduce the workload that operator checks one by one, reduce the work of quality in site, secure supervisor
It measures, it is ensured that concealed work quality.
Utility model content
When the existing grout sleeve reinforcing bar of the utility model needle is in the milk, the fixed device of grout sleeve reinforcement location is not utilized,
Reinforcing bar is inserted directly into grout sleeve operator and whether checks reinforcing bar in grout sleeve center, heavy workload by minute surface, and examines
Survey difficulty is big, and subjective factor influences apparent problem, provides for the grout sleeve reinforcement location fixator in grout sleeve,
The fixer structure is simple, easy to install, can reduce operator and check the workload whether reinforcing bar hits exactly one by one, reduces live matter
Amount, the workload of secure supervisor, it is ensured that concealed work quality.
The utility model is achieved through the following technical solutions：Grout sleeve reinforcement location fixator, in grout sleeve
Fixed steel bars are set in grout sleeve.The fixator includes cushion block and lock strap, and described cushion block one end is provided with card hole, institute
It states the other end of the cushion block far from lock strap card hole to be fixedly connected with lock strap one end, one end fits of the lock strap far from cushion block are provided with
The buckle of card hole can be stretched into；Diameter on the outside of the cushion block corresponding to camber line is smaller 1~5mm than grout sleeve internal diameter；The lock strap
It is clamped that form perimeter longer 0~10mm than reinforcing bar circular section perimeter with cushion block.
The application method of the fixator is：When assembling architectural prefab preparation, the cushion block on fixator is touched and waits filling
It starches on fixed reinforcing bar, is then inserted into the card hole of the cushion block other end, makes solid by lock strap around reinforcing bar and by the buckle in lock strap
Determine device to be tightly attached on reinforcing bar.The angled fixator that is arranged is no less than 2 on every reinforcing bar in same grout sleeve.If being arranged
Fixator when being 2, the cushion block on 2 fixators is located at the both sides of reinforcing bar, and vertical range is not up and down for 2 fixators
More than 5 times bar diameters after so that reinforcing bar is arranged grout sleeve, ensure that reinforcing bar is located at grout sleeve volume center position.Grouting is covered
Jacket casing is located at outside the reinforcing bar for being arranged with fixator, then carries out grouting fixation.Since grout sleeve internal diameter is slightly larger than on the outside of cushion block
Diameter corresponding to camber line, therefore grout sleeve is arranged and can be set in by being arranged on the reinforcing bar of fixator.
Further, the corresponding central angle of the cushion block is 85~100 °, it is preferred that the corresponding central angle of cushion block is 90 °.
Further, the cushion block is the circular arc block of width 5mm, high 10mm.Preferably, the card hole is width 1mm, high 5mm
Square hole.
Further, the diameter of a circle corresponding to the cushion block medial surface is identical as reinforcing bar outer diameter, and cushion block is made to be pasted with reinforcing bar
It closes more closely.The cushion block medial surface is provided with the horizontal stripe or vertical stripe for increasing cushion block and reinforcing bar frictional force, makes grouting
In the process, relative displacement does not occur between fixator and reinforcing bar.
Further, the buckle is to be provided with the binding bands of multiple unidirectional sawtooth, be equipped in the card hole with
The reversed latch of unidirectional sawtooth can adjust the length that buckle stretches into card hole according to the tight ness rating that is bonded between fixator and reinforcing bar
Degree, makes fixator be fitted closely with reinforcing bar.
Further, the lock strap is snap lock band；When snap lock band unclamps, snap lock band is clamped to form week with cushion block
Long to be less than reinforcing bar circular section perimeter, when snap lock band stretches, snap lock band is clamped to form perimeter more than or equal to steel with cushion block
Muscle circular section perimeter.
The utility model compared with prior art, has the following advantages and advantageous effect：
(1) grout sleeve reinforcement location fixator provided by the utility model is small, at low cost, simple in structure, can
Directly be set on reinforcing bar, reinforcing bar made to be fixed on the center of grout sleeve, reduce operator's hand inspection reinforcing bar whether position
Workload in reinforced bar sleeve center, while can also reduce due to quality problems caused by reinforcing bar offset in filling process, really
Protect concealed work quality.
(2) the utility model can also use snap lock band, so that lock strap is fitted closely with reinforcing bar, while being applicable to difference
The reinforcing bar of diameter keeps its scope of application wider.
