Description
Technical field
The present invention relates to the inside stirrup fixed structure of the bar-reinforced concrete member of the compression stress being subject to building construction pillar, shear wall, bridge pier, abutment etc., simplify the stirrup arrangement within bar-reinforced concrete member and improve application property, improve the ductility etc. of bar-reinforced concrete member to have the main muscle of the inside stirrup restraint bar-reinforced concrete member of regulation anchorage length, utilize the inside stirrup fixed structure of the bar-reinforced concrete member of stirrup fixation clamp or the fixing parts of stirrup.
Background technology
In general, the bar-reinforced concrete member of building construction and pillar, shear wall, bridge pier, abutment etc. is with the horizontally set stirrup around main muscle, thus fixing the main muscle of bar-reinforced concrete member and preventing frustrating of main muscle in the wrong, suppress the lateral displacement of the main muscle according to normal load, the brittle break preventing bar-reinforced concrete member to be subject to flash disruption by the plastic behavior of main muscle.
Fig. 1 is the plane graph of the layout presenting the inside stirrup connecting relative main muscle in the bar-reinforced concrete member of conventional art, Fig. 2 is the chart of the moment-curvature relation of the bar-reinforced concrete member presenting Fig. 1, and Fig. 3 is the plane graph arranging the internal stirrup of V-arrangement on the edge stirrup presenting and connecting relative main muscle in the bar-reinforced concrete member of conventional art.
In Fig. 1, bar-reinforced concrete member 100 makes main muscle 101 be arranged to square shape at predetermined intervals to direction anyhow, along main ribs 101 direction of principal axis and in main muscle outer periphery with the outside stirrup 102 of horizontally set, described outside stirrup 102 is internal is provided with internal stirrup 103 at predetermined intervals, fetters relative main muscle 101.
Described traditional bar-reinforced concrete member fetters main muscle because of outside stirrup with internal stirrup, frustrating of the main muscle of bar-reinforced concrete member can be suppressed in the wrong, according to inside and outside portion stirrup, the concrete within bar-reinforced concrete member suffers restraints, thus having the effect of the rigidity increasing bar-reinforced concrete member.
But, the inside stirrup of described traditional bar-reinforced concrete member is the form that its both ends retrain the main muscle of bar-reinforced concrete member with 90 degree or 135 degree of warpages, the both ends of described internal stirrup can produce, with the joggling part of 90 degree or 135 degree warpages, the phenomenon that fluffs when exceeding maximum endurance, as illustrated in Figure 2, reduce the bending moment of bar-reinforced concrete member, and to arrange internal stirrup after outside stirrup constraint bar-reinforced concrete member, therefore the construction of internal stirrup is less susceptible to.
In another embodiment of conventional art and Fig. 3, bar-reinforced concrete member 100 makes corner angle or the main muscle 111,112 of edge be arranged to square shape with direction anyhow, predetermined distance, along the main muscle 111,112 of described corner angle or edge direction of principal axis and with the outside stirrup 113 of horizontally set around main muscle
The edge main muscle 112 adjacent with corner angle main muscle 111 is provided with the inside stirrup 114 of the edge main muscle 112 relative with laterally constraint, the internal stirrup 115 of V-arrangement encases the outside of the main muscle 112 of edge, inside bar-reinforced concrete member prominent with V-arrangement, the both ends of the internal stirrup 115 of described V-arrangement are attached to described internal stirrup 114 by lashing wire, do not arrange with not interfering with or disturb each other mutually with the internal stirrup 115 of adjacent V-arrangement.
But, because described bar-reinforced concrete member arranges internal stirrup stirrup internal with V-arrangement after passing through the outside stirrup main muscle of constraint, constraint and the construction of internal stirrup and the internal stirrup of V-arrangement are less susceptible to.
Summary of the invention
(solving the technical problem that)
It is an object of the invention to, the inside stirrup fixed structure of a kind of bar-reinforced concrete member utilizing stirrup fixation clamp or the fixing parts of stirrup is provided, it is arranged on building construction and pillar, shear wall, bridge pier, the inside stirrup of the main muscle of the bar-reinforced concrete members such as abutment is formed by the internal stirrup of V-arrangement or U-shaped with regulation anchorage length, internal to V-arrangement or U-shaped stirrup is attached to main ribs as fixing means, bend and transversely deforming thus controlling frustrating of main ribs, adjacent V-arrangement or the internal stirrup of U-shaped are not set mutually with not interfering with or disturb each other and improve anchorage and the application property of the inside stirrup being attached to main muscle.
