Abstract
The utility model belongs to double steel pipe concrete beam column node in the frame core section of thick bamboo structure system of civil structure engineering field, including the outer steel pipe of steel core concrete column, interior steel pipe, hoop stiffener, concrete water smashes the hole, bolt hole, semi -girder upper limbs component and semi -girder low limbs component submit in on the outer steel pipe, interior steel pipe is arranged in in the outer steel pipe, semi -girder upper limbs component, semi -girder low limbs component extend to through horizontal stiffener level respectively interior steel pipe, and with outer steel pipe, interior steel pipe and hoop stiffener weld along the girth, it has the concrete to water to smash the hole to open on each horizontal hoop stiffener, the edge girth welds in the crossing plane of semi -girder upper limbs component, semi -girder low limbs component and outer steel pipe, and it is more reasonable that horizontal hoop stiffener enables the atress of semi -girder upper limbs component, semi -girder low limbs component.
Description
Technical field
The utility model relates to civil structure engineering field, espespecially in Frame-Shear wall system, and a kind of special bean column node when frame column adopts steel core concrete column.
Background technology
Along with super highrise building application increasingly extensive, Frame-Shear wall system is applied in the middle of design of building structures continually, Core Walls Structure generally adopts concrete structure, adopt the Frame-Shear wall of profile steel concrete column, especially more difficult in the node area construction having semi-girder component to cross in beam column node area, construction quality is more difficult to get guarantee; Adopt the Frame-Shear wall of steel core concrete column, construction quality easily ensures, can improve the compressive strength of post inner concrete outside post with inner side steel pipe, but under the effect of semi-girder component pulling force, steel pipe column post jamb easily and post inner concrete depart from, post inner concrete is also easily by drawing crack.
Summary of the invention
The utility model patent is a kind of two steel tube concrete beam and column node, and this device can reach bean column node and effectively be rigidly connected, and occurs the situation loosening landing when solving beam-to-column joint.
The utility model patent is a kind of two steel tube concrete beam and column node, comprise the outer steel pipe of steel core concrete column, interior steel pipe, ring stiffener, casting and compacting of concrete hole, bolt hole, semi-girder upper limbs component and semi-girder lower limb component, it is characterized in that, described semi-girder upper limbs component and semi-girder lower limb component intersect on outer steel pipe, interior steel pipe is placed in described outer steel pipe, described semi-girder upper limbs component, semi-girder lower limb component extends horizontally to described interior steel pipe respectively by ring stiffener, and with described outer steel pipe, interior steel pipe and ring stiffener weld along girth, described each ring stiffener has casting and compacting of concrete hole, described semi-girder upper limbs component, weld along girth in the plane that semi-girder lower limb component is crossing with outer steel pipe, ring stiffener can make semi-girder upper limbs component, semi-girder lower limb component stressed more reasonable.
As improvement, interior steel pipe is connected by ring stiffener with outer steel pipe.
As improvement, semi-girder upper limbs component, semi-girder lower limb component extend to described interior steel pipe respectively by lateral stiffening plate level.
As improvement, ring stiffener has 4 casting and compacting of concrete holes.
The beneficial effects of the utility model make steel pipe inner concrete stressed relatively more even, and most of concrete in tension is converted into pressurized, and stress form becomes more reasonable, and node is reliably safer.
Four. accompanying drawing explanation
Fig. 1 is structure graphics of the present utility model.
Fig. 2 is plan view of the present utility model.
(1) interior steel pipe in Fig. 1, (2) outer steel pipe, (3) casting and compacting of concrete hole, (4) bolt hole, (5) semi-girder upper limbs component, (6) ring stiffener, (7) semi-girder lower limb component.
Five. detailed description of the invention
Be illustrated in figure 1 the bean column node that semi-girder upper limbs component 5, semi-girder lower limb component 7 and hoop stiffening rib 6 intersect at the outer steel pipe 2 of steel core concrete column, hoop stiffening rib 6 is identical with the root absolute altitude of semi-girder lower limb component 7 with the end absolute altitude of lower flange of girder listrium, hoop stiffening rib 6 is identical with the elevation of top of the high same semi-girder upper limbs component 5 of the top mark of top flange plate, the present embodiment is only a kind of signal, as horizontal ring stiffener should according to various situation, be arranged in plane that semi-girder upper limbs component, semi-girder lower limb component and upper and lower frange plate and outer steel pipe collide.
Making and the assembled step of the utility model embodiment are as follows: by outer steel pipe 2 as on moulding bed, interior steel pipe 1 is positioned, overlap outside in steel pipe 2, ring stiffener 6 welds along girth with outer steel pipe 2 and interior steel pipe 1 respectively, semi-girder upper limbs component 5 welds with outer steel pipe 2 transmission being carried out power by hoop stiffening rib 6, semi-girder lower limb component 7 welds with outer steel pipe 2 transmission being carried out power by hoop stiffening rib 6, concrete is undertaken being filled between two steel pipes by the casting and compacting of concrete hole on hoop stiffening rib, make stressed evenly.Above the scheme that the utility model embodiment provides is introduced in detail, for one of ordinary skill in the art, according to the thought of the utility model embodiment, all will change in specific embodiments and applications.
As improvement, interior steel pipe (1) is connected by ring stiffener (6) with outer steel pipe (2).
As improvement, semi-girder upper limbs component (5), semi-girder lower limb component (7) extend horizontally to described interior steel pipe (1) respectively by ring stiffener (6).
As improvement, ring stiffener has 4 casting and compacting of concrete holes.
