Abstract
The utility model discloses a kind of joint of steel structure of high-intensitive Self-fastening, the joint of steel structure is by the steel matrix for being provided with inner hole, the pin shaft for being provided with centre bore to match with steel matrix inner hole and is fixed in centre bore and steel matrix and three parts of hard filler of pin shaft bottom junction form；The bottom of steel matrix is provided with the escape of high 5mm-8mm, pin shaft bottom is provided with and the consistent boss of withdrawing groove height, the bottom face of boss is provided with 110 ° -140 ° of wedge angle angle of conical ring, and the top of conical ring is located within the scope of the 1/3-2/3 of boss bottom face radius of circle.The steel construction of the utility model is suitable for that narrow space, bond strength are high, stability is good, Self-fastening, easy for installation.
Description
Technical field
The utility model relates to field of steel structure more particularly to a kind of joint of steel structure of high-intensitive Self-fastening.
Background technique
The welded connecting of steel construction can be directly connected to any orientation, angle and the shape of steel because having, and not cut
Weak member section, saving steel, simple structure is easily manufactured, and the rigidity of connection is big, good seal performance, preferably uses and is turned into automatically
The advantages that industry, high production efficiency and be widely used.Welded connecting is that the heat generated by electric arc makes welding rod and weldment part
Fusing condenses into weld seam through cooling, so that weldment be linked into an integrated entity.Steel in high-temperature soldering cooling procedure, near weld seam
Material because high temperature action forms heat affected area, due to non-uniform high temperature and it is cooling make structure generate residual stress and residual deformation and
Become fragile, has certain influence to the bearing capacity of steel construction, rigidity and service performance.
And in the case where certain extreme environments (such as operating space is small, strength of joint requires height), conventional any skill
Art all can not simple realization solidification.
And in the related patents applied at home at present, the prior art that do not welded specifically for narrow space, because
And need in the market it is a kind of suitable for narrow space, bond strength is high, stability is good, Self-fastening, steel construction easy for installation.
Summary of the invention
The utility model is intended to provide suitable for narrow space, bond strength is high, stability is good, Self-fastening, easy for installation
Steel construction.
To achieve the goals above, the utility model uses following technical scheme: a kind of steel construction of high intensity Self-fastening
Connector, the joint of steel structure is by being provided with the steel matrix of inner hole, the pin shaft for being provided with centre bore to match with steel matrix inner hole
And it is fixed in centre bore and three parts of hard filler of steel matrix and pin shaft bottom junction form；The bottom of steel matrix is set
It is equipped with the escape of high 5mm-8mm, pin shaft bottom is provided with to be provided with the consistent boss of withdrawing groove height, the bottom face of boss
The top of the conical ring that 110 ° -140 ° of wedge angle angle, conical ring is located within the scope of the 1/3-2/3 of boss bottom face radius of circle.
Compared with prior art, the utility model has the advantage that (1) for narrow space, due to not having
Enough operating spaces or (this mode is not suitable for small lot, paroxysmal welding with high-precision robot welding
It is required that) or disposable casting and forming, both modes have its limitation, and the utility model is by inserting carburizing after drilling
Pin shaft, then being vertically squeezed and deformed by pin shaft makes former cylindrical surface become the positive conical surface and the tangent acquisition anti-slip power of bottom hole escape,
Pass through centre-drilling hole again and fill out hard filler and solidify and stablize connector, forms welding structure, filler fills up rear pin shaft and loses change
Shape space can not become original shape again under extruding force to deviate from matrix, realize from solid lock.(2) the utility model can be with
It very simply realizes processing and installation, even only one air drill, also space can be drilled out using the drill bit of corresponding model, then adopted
It is inserted into mating pin shaft and is then compressed, reinjected the adhesive resin liquid solidification of normal temperature cure, simply implement.(3) this is practical new
Type selects (hardness when being tempered of not quenching is not high) after low-carbon alloy steel carburizing to be used as pin shaft especially datedly, reasonably avoids and quenches back
The defect that carburizing part hardness is high after fire, brittleness is big, while in a small range operation, it can directly pass through injection molten alloy steel
Liquid realizes the tempering of quenching of steel simultaneously.Therefore the steel construction of the utility model has high, steady suitable for narrow space, bond strength
Qualitative good, Self-fastening, characteristic easy for installation.
Detailed description of the invention
Fig. 1 is that the utility model installs structural schematic diagram before curing；
Fig. 2 is the structural schematic diagram after the utility model installation solidifies；
In figure: pin shaft 1, centre bore 2, steel matrix 3, escape 4, conical ring 5.
Specific embodiment
Embodiment 1:
A kind of joint of steel structure of high-intensitive Self-fastening as shown in Figure 1 and Figure 2, the joint of steel structure is by being provided with inner hole
Steel matrix 3, the pin shaft 1 for being provided with centre bore 2 to match with 3 inner hole of steel matrix and be fixed in centre bore 2 and steel matrix 3 with
Three parts of hard filler of 1 bottom junction of pin shaft form；The bottom of steel matrix 3 is provided with the escape 4 of high 8mm, pin shaft 1
Bottom, which is provided with, is provided with 110 ° -140 ° of wedge angle angle of conical ring 5 with the consistent boss of withdrawing groove height, the bottom face of boss,
The top of conical ring 5 is located at boss bottom face radius of circle at the 1/3 of the center of circle.
Embodiment 2:
The height and boss thickness of escape 4 are 5mm:
Embodiment 3:
It is whole consistent with embodiment 1, it is in place of difference:
140 ° of the wedge angle angle of conical ring 5；The top of conical ring 5 is located at boss bottom face radius of circle far from the 2/3 of the center of circle.
The foregoing description of the disclosed embodiments, only for can be realized professional and technical personnel in the field or use this
Utility model.Various modifications to these embodiments will be readily apparent to those skilled in the art, herein
Defined in General Principle can be real in other embodiments without departing from the spirit or scope of the present utility model
