Description
Technical field
This utility model relates to a kind of node, particularly relates to a kind of string and props up the stayed structure clamp device with upper chord
Node, belongs to field of steel structure.
Background technology
Suspended-dome structure is by the Reticulated Domes on top, prestressing force strop, the drag-line of bottom and contacts both
Strut forms, and has lightweight, and span is big, handsome in appearance, feature easily of constructing.Not only improve stablizing of single-layer latticed shell
Property, add span, and allow overall structure have certain initial stiffness.On in terms of construction, suspended-dome structure peso vault
Roof construction is easier to construction.The mechanics principle of suspended-dome structure is by strengthening tension in lower part integral part Shi Hanzhang
The rigidity of single-layer latticed shell, to improve structure tension performance, make structure become self equilibrium systems, therefore stretch-draw integral part
Pre-stress design is the key of such design, makes full use of the high-strength pulling-resisting of rope material, adjusts the internal force distribution of system, in reducing
Power amplitude, thus improve the bearing capacity of structure.This structure upper structure is that single-layer lattice shell is connected by solder sphere, and bottom string props up
Guy system is made up of strut, drag-line, and radial cable is reinforcing pull rod, and strut uses round steel pipe, upper end to use articulated with net shell rod member
Point, lower end is affixed with cord clip.So allowing upper chord prop up drag-line effectively be connected and fasten with bottom string by strut is one
Firm entirety, and do not make rope, strut, net mould component actual internal force size and distribution and different design, its connected mode
Just become is particularly important.
Utility model content
This utility model mainly solves the deficiencies in the prior art, it is provided that a kind of compact conformation is reasonable, and power transmission can
Leaning on, site operation is convenient, beneficially string prop up drag-line stretch-draw, the string of the security performance increasing structure props up stayed structure and top
The node of the clamp device of chord member.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
A kind of string props up the node of stayed structure and the clamp device of upper chord, including strut, upper chord and cross strength
Plate, the top of described strut is provided with flange semi-disc assembly, and described flange semi-disc assembly fixes with cross strength plate, institute
The upper chord stated is positioned mutually by cross strength plate, and the bottom of described strut is provided with cable wire hemisphere, in described cable wire hemisphere
It is provided with string and props up drag-line.
As preferably, described flange semi-disc assembly includes flange semi-disc and flange disk, described flange semicircle
Dish is located at the top of strut, is provided with welding lower semisphere, is provided with in welding in described flange disk in described flange semi-disc
Hemisphere, the bottom of described flange disk and the top of flange semi-disc fixes in laminating shape, described welding episphere and weldering
Connect lower semisphere in connecting distribution, bottom described welding lower semisphere and between flange semi-disc, be provided with plectane, described welding upper half
Ball is embedded in the bottom of cross strength plate, and the bottom of described upper chord is embedded in the top of cross strength plate.
As preferably, described flange disk is fixed by equally distributed bolt with flange semi-disc.
Welding episphere with weld lower semisphere and interlock formation arc transition, freely slidable.
Flange semi-disc is connected with upper flange disk by flange bolt, reach now without get angry according to, convenient fast
Prompt and have safety guarantee.
String props up drag-line and can slide in cable wire hemisphere in stretching process, can be connected with fastening after stretch-draw,
It is easy to construction.
Have the advantage that
(1), construction precision is high.Owing to strut top have employed two welding being articulated and connected of hemisphere, can simpler,
Accurate and effective carries out lower-chord panel point fastening, prevents the bias of drag-line, reduces the loss of stretching force.Thereby ensure that drag-line, perpendicular
To the prestressing force precision of strut etc..
(2), convenient and quick construction.The node of the clamp device that the string used props up stayed structure and upper chord passes through bolt
Connect, simple to operation, and construction precision is high, saves manpower and time.
(3), structure uses safety.Owing to using steel-casting to fasten, its bearing capacity is high, and can effectively prevent at lower edge
Local failure to securing member during cable tension, prevents securing member stress flexing, adds the safety of structure.
This utility model provides string to prop up the node of stayed structure and the clamp device of upper chord, compact conformation, is constructed into
This is low, and construction and installation are convenient, increases steel construction safety.
