The present invention relates to a kind of strong ties methods such as steel-casting, include the following steps：（1）, reinforce grommet processing：Reinforcing symmetrical grooving at the top of grommet, slot should not penetrate through bottom, and reinforcing grommet bottom should continuous, closing；（2）, to reinforce grommet group vertical：After the completion of steel member is stood with reinforcement grommet group, reinforcing using fillet weld full weld at grommet fluting；（3）, butting grooves processing：Steel member carries out retaining wall on slope together with reinforcement grommet, to increase steel member butting grooves size；（4）, the strong welds such as scene：Steel member is attached with after the completion of the positioning of steel-casting in-site installation using the strong butt weld such as full penetration.The present invention both ensure that the bearing capacity of weld seam at docking was not less than the bearing capacity of component itself, in turn avoid the stress concentration caused by thickness change is excessive.
Description
Technical field
The invention belongs to construction engineering technical fields, and in particular to a kind of strong ties method such as steel-casting.
Background technology
Conventional sheet welding node can not be often used with increasingly complexity, the steel construction complex node of building structure moulding
To realize.And steel-casting is widely used in above-mentioned big because of its good moulding flexibility, connection convenience, carrying adaptability
Type complex steel structure position of joints.The node of welding, curve form can not be spliced using conventional sheet and proximate matter by being mainly used in
Extreme irregular node, welding capacity be big and the node excessively concentrated, the node that cannot be met the requirements using general proximate matter bearing capacity.
But since the intensity of welding structure cast steel material is less than low-alloy high-tensile structural steel, simultaneously because design rule
The difference of provisioning request causes steel-casting wall thickness to be higher than low-alloy structural steel member.Steel-casting wall thickness is often low-alloy structural steel structure
1.5 ~ 3 times of part wall thickness, and the same low-intensity material of Weld Performance, the same thin plate of weld size, if therefore not taking corresponding etc. strong
Connection method necessarily causes junction weld seam low bearing capacity in component bearing capacity itself, wall thickness change is excessive causes stress concentration.
In the strong ties node such as conventional steel-casting, needs that a changeover portion is arranged, not only increased construction complexity, but also can not keep away
Junction stress concentration caused by exempting from wall thickness mutation.It is therefore desirable to the equal strong ties to steel-casting and low-alloy structural steel member
Method is studied, and proposes a kind of technical solution of innovation.Thus this case generates.
Invention content
The purpose of the present invention is to provide a kind of strong ties method such as steel-casting, this technical solution both ensure that and welded at docking
The bearing capacity of seam is not less than the bearing capacity of component itself, in turn avoids the stress concentration caused by thickness change is excessive.
To achieve the above object, the technical solution that the present invention specifically provides is：A kind of strong ties methods such as steel-casting, it is special
Sign is, includes the following steps：
（1）, reinforce grommet processing：Reinforcing symmetrical grooving at the top of grommet, slot should not penetrate through bottom, and reinforcing grommet bottom should connect
Continuous, closing；
（2）, to reinforce grommet group vertical：After the completion of steel member is stood with reinforcement grommet group, reinforcing sowing using fillet welding at grommet fluting
Weldering；
（3）, butting grooves processing：Steel member carries out retaining wall on slope together with reinforcement grommet, to increase steel member butting grooves
Size；
（4）, the strong welds such as scene：After the completion of steel member is positioned with steel-casting in-site installation, using the strong butt weld such as full penetration
It is attached.
Further, the reinforcement grommet outer diameter should be less than steel member internal diameter.
Further, the steel-casting wall thickness should be greater than steel member.
Further, the sum of the steel member wall thickness and reinforcing line ring wall thickness are not more than steel-casting wall thickness.
Compared with the strong ties constructions such as existing conventional steel-casting, the present invention has the following advantages：
（1）Reinforce grommet simple structure, convenient processing and manufacture；
（2）Changeover portion need not be set, on-site construction processes are reduced；
（3）Reinforce grommet bottom is continuous, closing, and polish flat, is conducive to the guarantee of welding quality；
（4）Reinforce grommet and increase steel member groove size, to form taper weld seam, so that section is eased up transition, be conducive to subtract
Few stress concentration.

Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, with reference to a preferred embodiment of the present invention
Attached drawing further explains in detail technical solution provided by the invention work.
A kind of steel-casting strong ties method of such as Fig. 1 ~ shown in Fig. 4 and its node are one of present pre-ferred embodiments.
The component being mainly concerned with has：Steel-casting 1, reinforces the strong butt welding such as grommet 3, increased butting grooves 4, full penetration at steel member 2
Seam 5 and reinforcement grommet fluting 6.
The steel-casting 1 should be welding structure steel-casting；The steel member 2 should be low-alloy high-tensile structural steel structure
Part；Reinforce 3 material of grommet with steel member material；2 wall thickness of steel-casting should be greater than steel member；The steel-casting 1 and steel
2 section form of component can be round, box；2 wall thickness of steel member is not more than steel-casting 1 with the sum of 3 wall thickness of grommet is reinforced
Wall thickness；
The reinforcement grommet 3 fluting size and quantity answer the bearing capacity calculation of reinforcement as needed to determine；
The increased butting grooves 4 should polish flat, and reduce the generation of defect in welding process；
