Abstract
The utility model relates to a coincidental joint of a net shell roof, comprising members and a joint. The utility model is characterized in that the members of the net shell members of different directions pass through the joint by crossing and coincidence at a concurrent place, a U-shaped fastening compacted by a steel plate is arranged and connected at crossing points, the four fastenings of each crossing point are in # shape and are connected by bolts. In the utility model, because the members are not cut and broken at the time of passing the joint, in the net shell, force is mainly directly transferred by the members at the joint, with brief force transfer and reasonable stress, and the fastenings only transfer the difference of internal force on the two sides of the members, therefore, the utility model has the advantages of small internal force of the fastenings, material saving, simple structure and convenient production, processing and installation, being suitable for the net shell joint and a flat plate net frame joint.
Description
The utility model belongs to Structural Engineering system in space in the building structure, is specially adapted to the node of rack and latticed shell structure.
Traditional rack and net shell node mostly are welded spherical node and bolted spherical node.Though these joint form experiences are ripe and safe and reliable, node must be born the whole internal force that transmit rack or net shell, thereby gusset material is wasteful, and each node place rod member must cut off, consumption man-hour, consumption material, the fabrication and installation workload is big, the processing technology complexity.Particularly because the needs of single-layer lattice shell resistance to overturning, careless slightly to net shell installation and processing required precision height, the accumulated error of every rod member will cause the bigger error of whole net shell, thereby increases the secondary stress of net shell and reduce the degree of safety of structure.
The purpose of this utility model is the superimposed node of a kind of grid shell roof of design, and its rod member does not need during by node to cut off, easy construction, stressed rationally.
The superimposed node of a kind of grid shell roof of the present utility model, form by rod member, node, it is characterized in that: the net shell rod member of different directions passes through node in crossing place rod member cross lamination, the place is provided with the fastener that is pressed into " U " type by steel plate in the crosspoint, and four fasteners in each crosspoint are " well " word and connect with bolt.
The superimposed node of a kind of grid shell roof of the present utility model, because all rod members of net shell do not cut off during by node, the rod member of different directions crosses up and down at the node place, tens meters loaded down with trivial details processing that long rod member repeatedly blocks had so both been avoided, can make rod member in the direct power transmission in node place again, node place and rod member etc. are strong; The rod member cross lamination is passed through node, connect rod member up and down with " U " type fastener, the main internal force in node both sides is transmitted at the node place by rod member, node " U " type fastener only transmits the internal force difference of node both sides and because the superimposed node reaction forces that causes of rod member, so just reduced node reaction forces greatly, therefore node " U " type fastener has not been main Force transmission parts, thereby can save gusset material in a large number.
The superimposed node of a kind of grid shell roof of the present utility model is applicable to net shell node and flat plate framed structure node.
Be described further below in conjunction with the superimposed node of drawings and Examples a kind of grid shell roof.
Fig. 1 is a kind of superimposed node schematic diagram of grid shell roof
Fig. 2 is a kind of superimposed node sectional drawing of grid shell roof
As seen from the figure, a kind of superimposed node of grid shell roof, form by rod member, node, it is characterized in that: the net shell rod member 1 of different directions passes through node in crossing place rod member cross lamination, the place is provided with the fastener 2 that is pressed into " U " type by steel plate in the crosspoint, and four fasteners in each crosspoint are " well " word and connect with bolt.Steel plate thickness is 12 millimeters, and connecting bolt is 16 millimeters of diameters.
