Abstract

The utility model relates to a shear beam for X bars in a building. The structure of the utility model is that upper and lower longitudinal bars and lacing bars are crossed and buckled to form an X-shaped plane frame structure, and cross points are welded and fixed by using transverse straight bars; the peripheries of the upper and the lower longitudinal bars are wound and fixed by using hoop bars. Both ends of the shear beam equivalent field-burning U-shaped slots whose interiors are welded with upper and lower connecting plates; the shear beam and shear force generation columns are welded through the connecting plates by using threaded rods; the end surface of the beam is provided with U-shaped clamp holes, and light material is added on a hollow position at the center of the beam. The shear beam has simple manufacturing process, and the steel degree and the shear stress resistant performance can be improved by more than three times; simultaneously, the cost is reduced, and the steel can be saved by more than 10%.

Description

" X " type muscle shear beam

The utility model relates to " X " type muscle shear beam in a kind of building

The present both at home and abroad extensively metallic framework technology of the reinforced concrete beam that adopts is all vertical muscle being arranged in parallel up and down of beam, will indulge muscle up and down by stirrup and encircle and be integral.This beam mainly is that stiffness is poor, and anti-shearing stress performance is poor, and ductility is lower, and reinforcing bar interts mutually with the concrete casting connection when beam is connected with post, makes the stressed complexity of node place concrete of Liang Yuzhu, destructible during earthquake.The utility model has designed a kind of " X " type muscle shearing fine strain of millet according to the weak point of metallic framework in the reinforced concrete structure high-rise building thing on the basis of CN95227571.6.

The purpose of this utility model is, on the basis of CN95227571.6, designed a kind of " X " type muscle shear beam, its vertical up and down muscle intersects to detain with lacing wire forms " X " type plane frame structure, weld with laterally straight muscle at each intersection button knot place simultaneously and fixed, twine with stirrup the periphery of vertical muscle up and down, at the two ends of fine strain of millet is equivalent cast-in-place U type groove, in U type groove, be welded with lower connecting plate, adopt dowel that shear beam and shear column are connected to integral body by junction plate, central hollow place shearing fine strain of millet adds light material, can prevent cold bridge, plays thermal insulation.But also weight reduction simultaneously.

Referring to accompanying drawing

Fig. 2 is the utility model bar construction figure

" X " described in the utility model type shear beam is to be intersected to buckle with lacing wire by vertical muscle up and down to tie shape Become " X " type plane frame structure, adopt laterally straight muscle to be welded and fixed at the place, crosspoint, about Stirrup compositions that be fastened adopted in the periphery of vertical muscle, and two ends that should " X " type shear beam are equivalent cast-in-place U-shaped groove (1) is welded with upper and lower type connecting plate (2) in U-shaped groove (1); The upper two ends of connecting plate (2) Have connecting hole (3), adopt the mode of dowel that shear beam and shear column are connected to integral body; Simultaneously Central hollow place in shear beam adds light material (4) can prevent cold bridge, plays the thermal insulation separation hotwork With, but simultaneously also weight reduction is provided with evenly distributed " U " type clamp hole (5) at the end face of beam.

Embodiment:

" X " described in the utility model type muscle shear beam, in manufacturing, at first the shear beam multi-disc is manufactured, to indulge muscle up and down ties with lacing wire intersection button, form " X " shape plane frame structure, and the mode of locating the employing welding in each crosspoint is fixed, according to actual needs, each plane framework is welded into whole shear beam with laterally straight muscle then, twines in the mode of spiral with stirrup again.Be welded into the periphery of whole shear beam, at the two ends of shear beam is that U type groove is now burnt in equivalence, in U type groove, be welded with lower connecting plate, two ends have the hole on the junction plate, the mode that adopts screw rod is connected and fixed the shear beam in the formation building and the framework of shear column with shear beam and shear column, central hollow place in shear beam adds light material and can prevent cold bridge simultaneously, play thermal insulation, but also weight reduction simultaneously, getting final product with concrete casting, is that the mode that adopts " U " type card to insert " U " type clamp hole on the beam-ends face is interconnected to integral body simultaneously between this beam and the spherical shell floor again.This shear beam manufacture technology is simple, and its stiffness, anti-shearing stress performance improve more than 2 times, reduce cost simultaneously, can save steel more than 10%.

Claims

1, a kind of " X " type muscle shear beam that is used to build thing, it is to be intersected to detain with lacing wire by vertical muscle up and down to tie, " X " type of formation plane frame structure, adopt laterally straight muscle welding fixing at the intersection point place, adopt the stirrup composition that is fastened in the periphery of vertical muscle up and down, it is characterized in that, the two ends of being somebody's turn to do " X " type shear beam are equivalent cast-in-place U type groove (1), in U type groove (1), be welded with upper and lower junction plate (2), junction plate (2) two ends are opened and are connected porose (3), adopt the mode of dowel that shear beam and shear column are connected to integral body; Central hollow place in shearing fine strain of millet adds light material (4) simultaneously; On the end face of beam, be provided with evenly distributed " U " type clamp hole (5).
