Description
Technical field
The utility model relates to the node structure in a kind of structural engineering, especially, relates to a kind of steel pipe column ring beam beam-column node structure.
Background technology
In structural engineering; Steel pipe column ring beam bean column node is constructed generally according to design shape, size; Beam main tendon is welded on the steel pipe column ring beam ring flat-plate all around; The steel hoop that increases gradually through the processing diameter is again installed around steel pipe column on lower ring plate on the steel pipe column ring beam, and carries out mechanical connection or welded closure processing.
See also Fig. 1 and Fig. 2, be respectively floor map and generalized section after existing steel pipe column ring beam bean column node construction is accomplished, the common job practices of this node structure does; According to design shape, size; Around steel pipe column 10 ring beam bean column nodes, beam main tendon 11 is welded on the steel pipe column ring beam ring flat-plate 12, the steel hoop 13 that increases gradually through the processing diameter is again installed around steel pipe column on lower ring plate on the steel pipe column ring beam as the anti-shear ring muscle; And carrying out mechanical connection or welded closure handles; Utilize lower ring plate reserving hole on the steel pipe column ring beam, wear sealing again after U type stirrup 14, waist muscle 15 and drag hook 16 colligations, adopt plintlet assembly unit typing round log mould at last; Face covers smooth thin veneer, and concreting is accomplished the construction of steel pipe column ring beam bean column node.
On the one hand, this steel pipe column ring beam beam-column node structure is high to the outer ring major diameter steel hoop requirement on machining accuracy around steel pipe column, and mechanical connection or be welded to connect the back and be prone to take place the sidewise buckling distortion is unfavorable for installation; On the other hand, this node structure reinforcement installation difficulty of construction is big, the formwork erection difficulty, and the phenomenons such as mould, spillage, dew muscle that when carrying out concreting, very easily rise have a strong impact on steel pipe column ring beam bean column node construction quality, influence construction speed simultaneously.
The utility model content
The main purpose of the utility model is to improve existing steel pipe column ring beam beam-column node structure; Avoid the higher major diameter steel hoop of machining accuracy; And overcome the difficult problem of annular formwork erection, and simplified the construction of node, improve construction quality and guaranteed construction speed.
Steel pipe column ring beam beam-column node structure after the utility model construction is accomplished is:
Comprise a steel pipe column; The last lower ring plate that is vertical setting with steel pipe column; And be welded on the complex root beam main tendon on the lower ring plate with steel pipe column is vertical setting equally, be provided with the plurality of rings steel hoop around said steel pipe column, said steel hoop be fixedly arranged on respectively said on the lower ring plate; The plural number stirrup wears and is fixed in the said lower ring plate of going up; And tied up plural drag hook and waist muscle on the said stirrup respectively, it is characterized in that: said steel hoop outer ring is provided with plural oblique haunch reinforcing bar, and said oblique haunch reinforcing bar is arranged between the adjacent beams.Preferably, on a ring flat-plate, the less steel hoop up and down of above-mentioned diameter is made as three circles, is equipped with two haunch reinforcing bars between the mutually perpendicular beam of adjacent twice.
Preferably, the length that anchors in the beam of said oblique haunch reinforcing bar meets the Lae length requirement.
Preferably, on a ring flat-plate, be made as three circles around the steel hoop of said steel pipe column, said oblique haunch reinforcing bar is made as two.
Preferably, be no more than 25mm around the less diameter of steel hoop up and down of steel pipe column diameter.
The beneficial effect of the utility model is: at steel pipe column ring beam bean column node place, replace around the high outer ring major diameter steel hoop of the requirement on machining accuracy of steel pipe column with the haunch reinforcing bar, avoid mechanical connection or be welded to connect the back sidewise buckling distortion takes place.Formwork erection is simple relatively, when carrying out concreting, is difficult for rising phenomenons such as mould, spillage, dew muscle, has guaranteed normal construction speed.

The specific embodiment
The following steel pipe column ring beam beam-column node structure of describing the utility model with reference to accompanying drawing 3-4 in detail.
After the construction of the utility model steel pipe column 20 ring beam beam-column node structures steel pipe column ring beam of the present invention bean column node is accomplished; Steel pipe column 20 ring beam beam-column node structures comprise the last lower ring plate 22 perpendicular to steel pipe column; Be welded in the complex root beam main tendon 21 on the lower ring plate 22, around steel pipe column and be fixedly arranged on the less plurality of rings of diameter on the lower ring plate 22 steel hoop 23 up and down, on a ring flat-plate; Wear the oblique haunch reinforcing bar 26 of complex root between the mutually perpendicular beam of adjacent twice; Steel hoop 23 is in the inside of haunch reinforcing bar 26, passes first stirrup 24 and first drag hook 25 of steel pipe column ring beam, beam-ends encrypted area second stirrup 29; The inner waist muscle 27 of ring beam and second drag hook 28 are the colligation relation with the above-mentioned stirrup 24 that passes the steel pipe column ring beam.
Preferably, on a ring flat-plate 22, the less steel hoop 23 of diameter is made as three circles, and the haunch reinforcing bar 26 that wears between the mutually perpendicular beam of adjacent twice is made as two, and is as shown in Figure 3.
Preferably, be no more than 25mm around less 23 diameters of steel hoop up and down of steel pipe column diameter among the present invention.
Such design scheme has replaced original major diameter steel hoop with haunch reinforcing bar 26, has avoided processing major diameter steel hoop, is convenient to install, and because of haunch reinforcing bar 26 is the straight shape of nature, before concreting, also need not to install annular template.
Though steel pipe column ring beam bean column node of the utility model and job practices are described with reference to current instantiation; But the technician in present technique field should be realized that; Above instance only is to be used for explaining the utility model, under the situation that does not break away from the utility model spirit, also can make in the scope of the variation of various equivalences and claims that modification all will drop on the utility model.
