Restraining structure carries out first step constraint, and the region that two rectangle hoops 6 intersect is to 3 effect of contraction of middle part reinforcing bar, then, close to yin
Two middle part reinforcing bars 3 at angle, then second step constraint, the first triangle u stirrup 7 and reinforcement steel are carried out by the first triangle u stirrup 7
The combination of muscle 5, which is realized, constrains enhancing to the first step of interactive areas.Column limb 2 external reinforcing bars 4 by the second triangle u stirrup 8 with
The second step that stiffener 5 connects shape paired column limb 2 constrains enhancing, and two structures form enhancing restraining structure.First triangle
Stirrup 7 prevents stiffener 5 from deforming outward, prevents stiffener 5 to be deformed inward for the second triangle u stirrup 8, passes through above-mentioned two
A triangle u stirrup keeps the fixation of stiffener 5, and 5 stable structure of stiffener is meant that, stiffener 5 passes through first
Triangle u stirrup 7 effectively constrains two middle part reinforcing bars 3 close to inner corner trim.
As a result, whole bar construction is stablized, and is unlikely to deform, is adequately constrained concrete, realized to yin
The protection at angle realizes the enhancing of total bearing capacity.
By connection type as shown in Figure 1, whole concrete structure is dispersed into various triangular by reinforcing bar and stirrup
Structure is constrained, and raising of the bar construction to the restriction ability of concrete is improved by way of breaking the whole up into parts.
Embodiment 3:
It please refers to shown in Fig. 1-2, the present embodiment and the difference of embodiment 2 are, by the longitudinal pitch for controlling all kinds of stirrups
With diameter, carry out the realization of assurance function, and control concreting effect, and control materials cost.
