Description
Technical field
The invention belongs to precast concrete technical field of construction, is in a row connected with complete more particularly, to one kind three and muscle
Grout sleeve and three and muscle connection method in a row.
Background technology
For mitigate architectural engineering, the field of civil engineering large span such as science of bridge building, heavy load concrete structure member from
Weight, generally requires to control the sectional dimension of the components such as beam, plate, column as far as possible, it may appear that reinforcing bar radical is too many on section in design
Too intensive situation, may cause concrete component construction to become complicated and be difficult to control with construction quality.
In actual design and work progress, civil engineers give the reinforcing bar configuration mode of " and muscle " solve by
The excessive position reinforcing bar radical of power excessively and it is excessively intensive and the problem of influence concrete pouring quality, world specification also has
Chapters and sections or provision on " and muscle ".
And muscle refers to bind 2,3 or more steel bar stresses, the cloth muscle in the form of tendon, wherein using more
It is two reinforcing bars and muscle (abbreviation：Double and muscle) and three reinforcing bars and muscle (abbreviation：Three pairs and muscle), three pairs simultaneously muscle can be with bunchy (i.e.
Arranged by triangle disposition) or be arranged in rows, as shown in Figure 1.
Assembled architecture refers to structural maintenance component needed for Prefabrication in the factory, building component, equipment system etc.,
The construction method of splicing installation is carried out after transporting to construction site.Assembled architecture is the needs of building industrialization, it is possible to achieve
Industrialization with standardized designs, factorial praluction, prefabricated construction, integration decoration and information system management etc. for main feature
The mode of production is built.All there is greater advantage in quality control, energy conservation and environmental protection, construction period and management etc..According to being adopted
Structural material point, assembled architecture can be divided into timber structure, steel construction and prefabricated concrete structure.Assembly concrete knot
Structure (Precast Concrete Structure) is assembled by precast concrete by reliable connection mode
Concrete structure, including assembled Integratde concrete struction, full assembling concrete structure etc..
Prefabricated assembled concrete structural bearing capacity, service life are suitable with traditional monolithic reinforced concrete structure, and have
There are short construction period, energy conservation and environmental protection, be more suitable for national conditions, there is preferable development potentiality in China.
The connection of reinforcing bar can be overlapped, welds or mechanically connected, wherein overlap joint is more generally by the way of.Work as concrete
Three and muscle in beam in a row using the overlap joint connection of binding when, every single should to stagger and gradually overlap, three and muscle is rows of takes
Spreading degree reply unit reinforcing bar is calculated and controlled respectively.When using mechanically connecting, the laterally minimum clear spacing of sleeve should carry out
Control, to ensure the pouring quality of concrete.
Limited be subject to execution conditions and assembly technology, the uses of the prefabricated components of prefabricated concrete structure causes prefabricated
The connection of reinforcing bar has expedited the emergence of many new modes between component, such as：Grout sleeve connection, extruding sleeve connection, slurry anchor overlap joint etc..
Reinforced bar sleeve grouting interconnection technique is mainly used for the bar connecting or reinforcing bar of pre-member in prefabricated concrete structure
The overall docking (Fig. 2) of cage, the so far existing history in more than 40 years.The performance of reinforced bar sleeve grouting connection is to assembly concrete knot
For structure, have the function that very important.From nineteen eighty-three, it is used as bar connecting main by ACI in report
After technology is included in, numerous scholars have carried out a series of research work to reinforced bar sleeve grouting interconnection technique in the world.It is related
Achievement is used by each mainstream specification including China's specification.
When in prefabricated concrete structure component because reinforcing bar radical is more and when introducing three and the rows of reinforcement manner of muscle, two
Between prefabricated components three and muscle it is in a row between connection become engineering circles one it is new the problem of, the connection of traditional prefabricated member reinforcing bar
Connection mode is directed to single steel bar, in traditional cast-in-place concrete three and muscle it is rows of overlap joint connection mode mixed in assembled
Simultaneously inconvenience, or even can not realize is used in Xtah Crude Clay structure.Although the connection mode of welding can be with high-altitude, scene etc. no
Ensureing the welding qualities of double muscle under sharp environment, there are many difficulties.

Steel, low-alloy high-tensile structural steel, structural alloy steel or other steel for being determined for compliance with requiring by joint geometry inspection carry out
Mechanical processing.Metal sleeve inner wall is equipped with shearing groove, forms shear connector, metal sleeve outer wall concrete outer with cylinder and metallic sheath
Interfacial failure is not susceptible in cylinder between grouting material and metal sleeve inner wall, interface connection is reliable.
5th, three and muscle anchorage length in a row it is smaller, i.e., three simultaneously the length be in a row inserted into metal sleeve of muscle it is smaller.Metallic sheath
Cylinder inner wall be equipped with shearing groove and use microdilatancy high strength grout, make grouting material and metal sleeve and three and muscle it is in a row between
Cohesive force, frictional force and mechanical snap power are relatively strong, thus only need less three and muscle anchorage length in a row and metallic sheath to length
Degree.
6th, using effect is good and practical value is high, economical and practical, can be rapidly completed three and muscle connection procedure in a row and connection
Reliably, while to three and muscle accuracy of alignment in a row relatively low, easy to operate, saving of work and time is required, construction efficiency is high, and switching performance can
Lean on, it is with good economic efficiency.By the optimization and restriction to metal sleeve Each part and size, connection method is applied
Work step is rationally designed suddenly, reaches that overall dimensions are small, occupy little space, to save material, simple process, dependable performance equivalent
Fruit.When carrying out three and muscle connection construction in a row using the present invention, it is not necessary to which large-scale or complicated mechanical equipment and equipment, is also not required to
It is equipped with special power supply, the close dry operation in construction site, energy conservation and environmental protection.To sum up, the present invention combines sleeve grouting connection peace treaty
The advantage of the methods of beam slurry anchor connection, solve in prefabricated concrete structure between prefabricated components three and muscle in a row connect it is tired
Difficulty, connecting arrangement is reliable, and processing and fabricating and construction is simple are easy, and comprehensive performance ratio is very high.
7th, widely applicable and popularizing application prospect is extensive, can apply to the prefabricated structure of the assembly concretes such as beam, plate, wall and column
The three simultaneously rows of connection of muscle between part.
