Abstract
The utility model relates to a net shell node, in particular to a backstay cable net shell node and is applied to the field of construction steel structures. The backstay cable net shell node comprises a node ball, wherein a guide pipe penetrates through the node ball; a prestressed inhaul backstay cable is arranged in the guide pipe; and the tail of the prestressed inhaul backstay cable is arranged on an outer wall of the node ball. The backstay cable net shell node is simple in structure, accurate in structural assembling and positioning, reasonable and effective in structural force transfer, reliable in structural performance and relatively low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of net shell node, relates in particular to a kind of rope and draws net shell node, is applicable to the construction steel structure field.
Background technology
At present prior art in recent years, along with the raising of architectural design level and the development of process equipment and constructional materials, the research of the theory and technology of prestressed steel structure has also obtained deep development.For satisfying the architectural image requirement, various prestressed steel structures have also obtained utilization in a plurality of engineering reality, and have obtained good social benefit and economic benefit.Simultaneously, also adopted various supporting with it joint form.
The utility model content
The utility model mainly is to solve the deficiency that exists in the prior art; Provide a kind of simple in structure; And this node is different from general prestressed node, but drag-line is directly penetrated the bolted node sphere of main structure, thereby guarantees that power transmission is clear and definite more, effectively rope draws net shell node.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of rope draws net shell node, comprises bolted node sphere, is installed with guide pipe in the described bolted node sphere, is provided with prestressed cable in the described guide pipe, and the afterbody of described prestressed cable is located at the outer wall of bolted node sphere.
The perforation at the bolted node sphere place is so that drag-line directly penetrates (locus and angle coding according to drag-line utilize numerical control device accurately to bore a hole).Prestressed cable is passed bolted node sphere, and control the specification that penetrates angle and guide pipe well, satisfying the required minimum gauge requirement of power transmission, and guide pipe and bolted node sphere are welded.Processing needs use the numerical control device blanking during bolted node sphere in factory, guarantees the size and the angle of position, hole on the bolted node sphere, the assembly unit completion at the scene of guide pipe and bolted node sphere, situations such as the dislocation that occurs when avoiding causing on-site consolidation because of error, mistake seam.
As preferably, the outer wall of described bolted node sphere is provided with the drag-line bracing frame, and described guide pipe and drag-line bracing frame fix, and the afterbody of described prestressed cable and drag-line bracing frame fix, and the head of described guide pipe is provided with steady position cover.
As preferably, be provided with ribbed stiffener in the described bolted node sphere, described ribbed stiffener is located at the outer wall of guide pipe.
The utility model provides a kind of rope to draw net shell node, and is simple in structure, structure assembly unit accurate positioning, and the structure power transmission is rationally effective, and structural performance is reliable, and manufacturing cost is relatively low.
