Abstract
The invention mainly discloses an equal-strength connecting joint and an equal-strength connecting method for components and plates made of different materials. The equal-strength connecting joint comprises a low-strength material component, a high-strength material component, transition sections and reinforcement plates. The components can be circular or box-shaped components, and internal reinforcement weld seams are welded via the transition sections, so that the circular components and cast steel can be connected with one another. The reinforcement plates are welded on the inner walls of the box-shaped components in advance, so that the components and the cast steel can be connected with one another in an equal-strength manner. The equal-strength connecting joint and the equal-strength connecting method have the advantages that steel materials which have different thicknesses and are made of the different materials can be connected with one another in an equal-strength manner, accordingly, the stress performance of the steel materials can be sufficiently played, and the safety of structures can be guaranteed; the equal-strength connecting joint is clear and definite in force transferring path, simple in structure, convenient to operate and high in efficiency.
Description
The present invention is application number is " 201310320790.7 ", themes as the division of " strong ties node and the method thereof such as a kind of unlike material component sheet material ".
Technical field
The present invention relates to construction steel structure technical field, be specifically related to a kind of strong ties methods such as unlike material component sheet material.
Background technology
Along with the development of national economy, green steel building progressively increases, and the material capability of steel also progressively improves, and carries out study and use to high-strength steel, as the Q420 high-strength steel that Beijing New Poly Building uses, and the Q460 high-strength steel used in the Bird's Nest of National Stadium.Due to increasing of steel type, in one structure according to diverse location stress performance situation, the situation of different thickness of slab and different performance material steel is adopted also progressively to increase, to realize the economy of construction cost.Meanwhile, complicated and changeable along with form of structure, in complex node position in order to ensure presentation quality and the stress performance of node, the application of integrated poured cast steel node also gets more and more.
But, because steel material performance is different, if need to realize the strong ties such as steel between the two, will inevitably be that low-intensity material steel are thick, the steel of high strength material are thin, when steel adopt melt-through weld to dock, will form Weld Performance is low-intensity material, and throat depth can only with the thin plate of high strength material, so weak spot will be formed at position while welding, thus reduce the stress performance of structure, and this problem is not often designed person's ignorance, brings larger hidden danger to structural safety.
Summary of the invention
The present invention obtains object and is to provide strong ties node and the methods thereof such as a kind of unlike material component sheet material, by increase weld seam realize different-thickness, unlike material steel etc. strong ties, give full play to the stress performance of steel, ensure the safety of structure.Force path in the present invention is clear and definite, simple structure, and easy to operate, efficiency is higher.
In order to achieve the above object, the present invention is achieved through the following technical solutions:
The strong ties nodes such as a kind of unlike material component sheet material, comprise low strong material members, high-strength material members, stiffening plate, changeover portion; Stiffening plate is formed inside high-strength material members, stiffening plate is the contract oralia pouring into a mould machine-shaping with low strong material members one, low strong material members welds the changeover portion that a section highly exceedes stiffening plate, high-strength material members is welded on changeover portion, and stiffening plate is identical with low strong material members with the integral thickness of high-strength material members.
Described low strong material members is integrated poured shaping steel-casting.
Described changeover portion is the individual member that high-strength material members is made.
For above-mentioned different schemes, the present invention adopts with the following method:
A kind of strong ties methods such as unlike material component sheet material, projection contract mouth is processed at the port inner ring position of low strong material members, form stiffening plate, changeover portion is fitted in stiffening plate, be connected by the port of butt weld with low strong material members, utilize changeover portion port space, by stiffening plate inside fillet weld seam and changeover portion, finally utilize backing plate to adopt melt-through weld to dock changeover portion and high-strength material members.
Described changeover portion is the individual member that high-strength material members is made.
After adopting such scheme, the present invention has many beneficial effects:
The present invention, by the strengthening action of stiffening plate, compensate for different-thickness, unlike material steel etc. when docking by force, due to the impact of material and thickness of slab, forms weak spot in docking melt-through weld position.Make component internal force pass through docking melt-through weld and fillet weld jointly transmit, ensure that structural safety.Joint structure is succinct, does not affect outward appearance, and power transmission is directly, clearly, easy to process.
Accompanying drawing explanation
Fig. 1 is present pre-ferred embodiments generalized section;
Fig. 2 is the concrete schematic diagram of connection of present pre-ferred embodiments.
Detailed description of the invention
What the present invention mainly solved is by low strong material members 1(such as steel-casting), with high-strength material members 2(such as common iron component) connectivity problem.
Composition graphs 1,2, in the present embodiment, low strong material members adopts pipe steel-casting 1, when docking with high-strength material members 2, waits strong ties in order to satisfied, first builds to add to form a circle projection contract mouth man-hour at low strong material members inner ring position, as stiffening plate 6.The port of stiffening plate 6 and pipe steel-casting 1 forms a breach.This breach places a changeover portion 4, is first connected with pipe steel-casting 1 port by changeover portion 4 by butt weld 3, then by changeover portion 4 port space, welding inner side Strengthening corner weld seam 5, realizes the connection between changeover portion 4 and stiffening plate 6.Finally the backing plate 7 being a little welded in medial surface is utilized to adopt melt-through weld to dock changeover portion 4 and high-strength material members 2.Wherein changeover portion 4 is identical with high-strength material members 2 material.
Above-described embodiment only illustrates inventive concept of the present invention for explaining, but not the restriction to rights protection of the present invention, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should fall into protection scope of the present invention.
