Description
Technical field
Patent of the present invention relates generally to reinforcing bar in a kind of concrete frame node（Antidetonation）Anchoring process belongs to building skill
Art field..
Background technology
According to the requirement of building structure construction specification and design, concrete and rebar can be effectively bonded together, and be played
Go out respective advantage, benefited for the mankind, reaches our research and use purpose.So reinforcing bar can with coagulation local soil type integrator,
It has to the anchorage length for having enough in concrete, and competence exertion goes out the effect of its tension, and otherwise concrete and rebar must
It will detach, can not work together, i.e., destroying occurs in component.
In engineering design, for frame middle layer end node, beam longitudinal reinforcement is in the anchoring at Column border node position, when adopting
With beam muscle 900When bending anchoring, it is desirable that the vertical muscle of beam stretches into straight anchor length in column and is not less than 0.4Lab (0.4LabE), this parameter is closed
It is to column cross-section size, the diameter of anchor bar and strength grade, concrete strength and reinforcing bar type etc..And in putting into practice, often
Appearance local location stretches into straight anchor length in column there are the vertical muscle of beam and is less than 0.4Lab (0.4LabE), the processing of usual such situation
Method is that muscle replacement will be indulged in beam is minor diameter, but this way often occurs that number of steel bars is excessive at bean column node, sometimes
The construction of concrete at bean column node can be seriously affected, on the other hand as what is replaced is the elongated muscle of beam, that is, there is taking for reinforcing bar
It connects, while many inconvenience is brought to construction, increase the workload of construction arrangement of reinforcement, and waste steel..
Invention content
The technical problem to be solved in the present invention overcomes existing defect, provides reinforcing bar in a kind of concrete frame node
（Antidetonation）Anchoring process, by using the method for pasting weldering dowel in main reinforcement side, anchoring overall length is La (LaE).This anchoring process,
The vertical muscle for improving beam stretches into straight anchor length in column and must not drop below 0.4Lab (0.4LabE) condition limitation defect；Additionally by
Using this anchoring process, the excessive phenomenon of number of steel bars at bean column node is avoided because of caused by Reinforcement Replacement, while also avoiding
Therefore the inconvenient phenomenon of construction caused by, reduces construction arrangement of reinforcement workload, and consumption construction site some extra reinforcing bars are short
Head, it is not only energy saving but also save trouble, and increase construction site and handle the flexibility of such anchoring matters, while can effectively solve background
The problems in technology.
In order to solve the above technical problem, the present invention provides the following technical solutions：
Mainly there is provided a kind of for reinforcing bar in concrete frame node by the present invention（Antidetonation）Anchoring process realizes this method
The need component and fitting that installation is complete or work include：It calculates and measures and cutting 5d (vertical muscle diameter) bar dowel, bar dowel and main reinforcement
Patch weldering calculates main reinforcement La(LaE) length with determine inflection point, bending main reinforcement（900）, installation and binding main reinforcement etc..The meter
It calculates and measures and cut long 5d (vertical muscle diameter) bar dowel, be to have to do a job in a kind of mechanism anchorage method, it is long
5d (vertical muscle diameter) bar dowel is the accessory of such anchorage style can utilize steel bar stress end using such anchorage style
Anchor head increases anchoring bearing capacity to the local squeezing action of concrete；The bar dowel head is welded with main reinforcement patch, is that will cut
Good bar dowel head is welded with main reinforcement, is a kind of way of mechanical anchor, in order to ensure certain anchoring bearing capacity, is needed
Control certain straight anchor length and welding quality；The calculating main reinforcement La(LaE) length with determine inflection point, be by La
(LaE) require to determine the total anchorage length of main reinforcement, by code requirement, when using mechanical anchor length, main reinforcement La(LaE) length
0.6 L can be foreshortened toab (0.6LabE), i.e. anchorage length correction factor ζa0.6 is can be taken as, and according to column cross-section size, column
The factors such as muscle diameter determine the inflection point of main reinforcement；The bending main reinforcement（900）, according to fixed inflection point, to main reinforcement reality
Apply 900Bending；The installation and binding main reinforcement, are that the main reinforcement that will have been bent is placed into corresponding position, and fixes.
As a preferred technical solution of the present invention, the calculating simultaneously measures and cuts 5d (vertical muscle diameter) bar dowel, leads to
It crosses and uses bar dowel head, take full advantage of the waste material of construction site, it is not only energy saving but also save trouble, change Fei Weibao, reduces investment outlay into
This.
As a preferred technical solution of the present invention, the bar dowel is welded with main reinforcement patch, is a kind of mechanical anchor side
Formula increases anchoring bearing capacity to the local squeezing action of concrete using steel bar stress end anchor head, therefore to control certain
Straight anchor length and welding quality.
As a preferred technical solution of the present invention, the calculating main reinforcement La(LaE) length with determine inflection point,
Use such mechanical anchor mode, main reinforcement La(LaE) length can foreshorten to 0.6 Lab (0.6LabE), i.e. anchorage length
Correction factor ζa0.6 is can be taken as, the flexibility that construction site handles such anchoring matters, and energy saving and province are not only increased
Thing.
As a preferred technical solution of the present invention, the bending main reinforcement（900）, it is to be more than 0.2L because existingab
(0.2LabE) length main reinforcement can not straight anchor in column, can only be handled by bent anchor, while also increasing such anchorage style
Safety stock.
Compared with prior art, using technical solutions according to the invention, it can reach following advantageous effect：
1, weldering mechanical anchor is pasted with unilateral side using such bent anchor and is combined mode, the vertical muscle for improving prior art central sill stretches into column
Interior straight anchor length must not drop below 0.4Lab (0.4LabE) condition limitation defect.
2, the bar dowel head that long 5d is welded using unilateral patch is improved waste material live in the prior art and is unable to fully close
Reason uses, and the defect that main reinforcement anchor type is single.
3, weldering mechanical anchor is pasted with unilateral side using such bent anchor and is combined mode, main reinforcement La(LaE) length can shorten
To 0.6 Lab (0.6LabE), between two kinds of anchorage styles in existing technology, improves and handle such anchoring thing in the prior art
The defect that suitable underaction, expense material are taken a lot of work again.
4, weldering mechanical anchor is pasted with unilateral side using such bent anchor and is combined mode, improve anchorage style peace in the prior art
Not high enough defect is laid in entirely.
