Abstract
A lower-chord panel point structure for truss beam, comprising: truss beam lower edge, and distinguish welding node plate at the external surface of described truss beam lower edge along different directions, described gusset plate is for connecting the truss beam connecting rod from different directions be connected with truss beam lower edge.The utility model beneficial effect: the truss beam lower-chord panel point structure that band of the present utility model is encorbelmented, can adapt to the connection of the web member of truss beam lower edge and Different Plane, ensures that truss beam is connected with the firm of cantilevered structure, improves the integrally-built stability of truss beam.
Description
Technical field
The utility model relates to truss beam technical field, particularly relates to a kind of lower-chord panel point structure of truss beam.
Background technology
The power distribution equipment that current transformer station commonly uses has GIS and HGIS.GIS is gas-insulated gas insulated metal enclosed swit chgear, and HGIS is the semi-enclosed combined electrical apparatus of gas-insulated.Both difference are that HGIS bus is arranged on outside combined electrical apparatus, and GIS bus is arranged within combined electrical apparatus.HGIS price is low, can bidirectional outlet, facilitate the later stage to extend, therefore HGIS uses more in engineering.But HGIS floor space is large, limit HGIS in the narrow and small and place of the harsh environmental conditions application of transformer station's area.
Adopt the scheme of hanging wire point of encorbelmenting outside truss beam can reduce the floor space of HGIS, but in implementation process, main exist following difficulty:
Truss beam cantilevered structure is greatly stressed, and joint structure is complicated, and main truss beam is when being connected with truss beam cantilevered structure, in order to ensure that truss beam is integrally-built stable, need to connect the web member from multiple Different Plane, technology realizes there is larger difficulty, and tie point is easily out of shape.
Further, for truss beam agent structure itself, when truss beam lower edge is connected with each support web member of truss beam, there is the situation that truss beam lower edge is connected with the web member of Different Plane equally, structural unstable problem can be faced equally.
Utility model content
The purpose of this utility model is exactly to solve the problem, and proposes a kind of lower-chord panel point structure of truss beam, and this structure can ensure that the connecting rod in each plane of truss beam is stable and connect, and improves the integrally-built stability of truss beam.
To achieve these goals, the utility model adopts following technical scheme:
A lower-chord panel point structure for truss beam, comprising: truss beam lower edge, and distinguish welding node plate at the external surface of described truss beam lower edge along different directions, described gusset plate is for connecting the truss beam connecting rod from different directions be connected with truss beam lower edge.
The truss beam connecting rod of described different directions and gusset plate distinguish prepared screw-bolt hole.
The cross section of described truss beam lower edge is circular or polygon.
The external surface of described truss beam lower edge at least connects the gusset plate of 4 different directions.
The beneficial effects of the utility model are:
Truss beam lower-chord panel point structure of the present utility model, can adapt to the connection of the web member of truss beam lower edge and Different Plane, ensures that truss beam is connected with the firm of cantilevered structure, improves the integrally-built stability of truss beam.
Accompanying drawing explanation
Fig. 1 is the lower-chord panel point structure level direction sectional view of the utility model truss beam;
Fig. 2 is the lower-chord panel point structure vertical direction sectional view of the utility model truss beam;
Wherein, 1 truss beam lower edge, 2 truss beam flat sided straight web members, 3 truss beam plane diagonal web members, 4 Cantilever Beams planes are flat bar of encorbelmenting tiltedly, 5 frame girder facade vertical web rod, 6 Cantilever Beams tapered plane diagonal web members, 7 gusset plates, 8 connecting bolts.
Detailed description of the invention:
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
A kind of lower-chord panel point structure of truss beam, as shown in Figure 1-2, comprise: truss beam lower edge 1, distinguish welding node plate 7 at the external surface of described truss beam lower edge 1 along different directions, described gusset plate 7 is for connecting the truss beam connecting rod of the different directions be connected with truss beam lower edge 1.The truss beam connecting rod of different directions and gusset plate 7 distinguish prepared screw-bolt hole.
Specific implementation process is as follows:
Truss beam lower edge 1 welds 4 pieces of gusset plates 74 Different Plane, as shown in Figure 2, difference prepared screw-bolt hole on gusset plate 7.Truss beam flat sided straight web member 2 and truss beam plane diagonal web member 3, Cantilever Beams plane tiltedly flat encorbelment bar 4, truss beam facade vertical web rod 5, Cantilever Beams tapered plane diagonal web member 6 respectively prepared screw-bolt hole be connected with gusset plate 7 with by bolt, form multidirectional stressed complex node with truss beam lower edge 1, the enforcement for truss beam provides strong support.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
