Description
Technical field
This utility model relates to a kind of node for steel frame, and more specifically, this utility model relates to a kind of novel assembled steel framework cast steel node.
Technical background
Steel frame technique usually requires that and is rigidly connected between frame column and Vierendeel girder and requires that support and bean column node are hinged.But, in current steel-frame structure, the ability that conventional bean column node is not attached with support, it is necessary to connecting elements is additionally set, thus causing that processing and installation process are complicated, it is unfavorable for realizing fabricated construction.Traditional bean column node stiffening element then requires over through welding butt weld and completes to be connected with steel pipe column fixing and support connecting elements to also need to other welding with the connection of beam or post, often result in the attachment weld phenomenon that even cross close with bean column node weld seam, so that joint core region is subject to bigger welding heat affected, not only result in steel performance to degenerate, and also can affect, at the weld seam of rear welding, the Weld Performance formerly welded.
Utility model content
The purpose of this utility model overcomes above the deficiencies in the prior art exactly, and a kind of novel assembled steel framework cast steel node is provided for this, so that the node that connects of steel-frame structure reduces welding under the premise meeting node mechanical property and reduces welding heat affected, simplify construction technology, it is simple to the realization of fabricated construction simultaneously.
The technical solution of the utility model is:
A kind of assembled steel framework cast steel node, including the ring flat-plate being cast integrally and being provided with hollow, the uniform flange plate that is provided with of the outer periphery of described ring flat-plate, the inner side of described flange plate is provided with otic placode, and the edge of described ring flat-plate hollow is provided with prefabricated weld groove.
The flange plate quantity of the uniform setting of outer periphery of described ring flat-plate is 24.
The beneficial effects of the utility model are: can reduce steel-frame structure and connect being welded to connect of node, thus reducing the impact of sweating heat and simplifying construction technology, it is adaptable to many, tall steel frame and concrete-filled steel tubular frame structure, it is simple to the realization of fabricated construction.

Detailed description of the invention
In order to make advantage of the present utility model and feature be easier to be understood, below in conjunction with drawings and Examples, its technical scheme is described in detail.
Fig. 1 illustrates structure situation of the present utility model.
With reference to Fig. 1, assembled steel framework cast steel node of the present utility model, including being cast into one and having the ring flat-plate 1 of hollow, the outer periphery of described ring flat-plate 1 is uniform arranges flange plate 2, the inner side of described flange plate 2 is provided with otic placode 3, the prefabricated weld groove 1-1 in edge of described ring flat-plate 1 hollow position.
In of the present utility model setting: the flange plate 2 that outside described ring flat-plate 1, surrounding is uniform can be 24, it the embodiment shown in Fig. 1 is 4.
Fig. 2 illustrates this utility model one of the embodiment for steel frame, and labelling 7 therein is cast steel node.
With reference to Fig. 2, it is provided with the cast steel node 7 of two opposing installations in this embodiment, two described cast steel nodes 7 are sleeved on the upper side and lower side in the middle part of Steel Frame Column 5 with its ring flat-plate 1 respectively, and are connected with described Steel Frame Column 5 by described ring flat-plate 1 in not through welding butt welding mode by the prefabricated weld groove 1-1 on described ring flat-plate 1；In the present embodiment, the flange plate 2 that outside described ring flat-plate 1, surrounding is uniform is 4, therefore 4 flange plates 2 on each described cast steel node 7 are connected with the wing plate of 4 steel-frame beams 4 respectively；And 4 otic placodes 3 on each described cast steel node 7 are respectively articulated with 4 steel frames with otic placode and support 6.
Assembled steel framework cast steel node of the present utility model, flange plate 2 number needs of its described ring flat-plate 1 arranged outside is corresponding to the quantity of coupled described steel-frame beam 4.
Assembled steel framework cast steel node of the present utility model is casting, and its material property and processing and fabricating must meet the requirement of existing China Engineering Construction Standardization Association standard " cast steel node technical regulation ".
When assembled steel framework cast steel node of the present utility model is used to steel frame, its installation method is:
(1) first in processing factory, described cast steel node 7 is welded to connect with described Steel Frame Column 5, welding manner is: adopt the butt weld of not through welding along described prefabricated weld groove 1-1 welding, thus being greatly reduced welding heat affected, and eliminate seam inspection operation；
(2) to scene, described steel-frame beam 4 and steel frame being supported 6 again to be connected on described cast steel node 7, connection is characterized by:
When A) connecting described steel-frame beam 4, the flange plate 2 outside described cast steel node 7 upper ring plate 1 need to be made corresponding to the position of described steel-frame beam 4 wing plate, and then employing is welded to connect, bolt connects or the wing plate of described steel-frame beam 4 is connected by bolt-weldering Hybrid connections mode with described flange plate 2；
B), when the steel frame that connection is described supports 6, can adopt bolt or bearing pin that described steel frame supports 6 hinged with the otic placode 3 on described cast steel node 7.
This utility model is applicable to many, tall steel frame and concrete-filled steel tubular frame structure, application requiring, frame structure adopts square or square-section steel pipe column, the steel column of the square or square-section that shaped steel splices or round steel tubing string can also be adopted as structural column, and adopt the H profile steel Vierendeel girder 4 of rolling or the H-shaped steel-frame beam 4 being welded, it can be the pipe with otic placode as shown in Figure 2 that the steel frame hinged with the otic placode 3 on described cast steel node 7 supports 6, it can also be the round steel with otic placode, drag-line, square tube, the components such as H profile steel and cross steel, can also is that the steel plate being provided with bolt hole, the components such as angle steel.The former is hinged with the otic placode 3 on described cast steel node 7 by otic placode, and the latter is hinged with the otic placode 3 on described cast steel node 7 by its bolt hole.
When assembled steel framework cast steel node of the present utility model is used to concrete filled steel tube rod structure or the shaped steel splicing concrete column structure of concrete filled, without arranging stiffening element in its steel pipe, in order to steel pipe concrete filled casting and constructing.
