Abstract

The utility model relates to the field of buildings, and aims at providing a connecting mechanism for limiting a lower string cable of a string beam. The connecting mechanism comprises an upper string beam, a supporting rod, an inhaul cable, an angle brace and a roof purline, wherein the upper end of the supporting rod is hinged to the upper string beam, the lower end of the supporting rod is connected with the inhaul cable through a panel point device, the two ends of the stretched inhaul cable are fixedly connected with the two ends of the upper string beam respectively, and the inhaul cable forms a broken line which is in axial symmetry. The two ends of the angle brace are connected to the panel point device and the roof purline respectively. On the basis of keeping a planar structural system of the string beam, the connecting mechanism is simple, effectively guarantees outer stability performance of a structure plane, improves integral bearing force of a structure and expands the using range of an original planar string beam. Compared with a space string beam structure, the connecting mechanism is simple in engineering construction, higher in construction speed and lower in cost.

Description

A kind of for opening the spacing bindiny mechanism of string beam last quarter rope

Technical field

The utility model is about building field, and is particularly a kind of for opening the spacing bindiny mechanism of string beam last quarter rope.

Background technology

The tension string beam structure form of using always in the large span engineering is more with the space tension string beam structure at present, mainly contains unidirectional tension string beam structure, two-way tension string beam structure, multidirectional tension string beam structure and radiant type tension string beam structure.Unidirectional tension string beam structure has guaranteed out-of-plane stability owing to be provided with the space-load system that the longitudinal bracing rope forms, and is applicable to the roof structure of rectangle plane.Two-way tension string beam structure has formed vertical and horizontal space-load system because crossing plane is opened the string beam resiliency supported is provided mutually, and this structure is applicable to multiple plane roof structures such as rectangle, circle, ellipse.Multidirectional tension string beam structure is the space-load system that the plane tension string beam structure forms along a plurality of direction arranged crosswise, and this form of structure is applicable to the roof structure of circular and polygon plane.The radiant type tension string beam structure be by central authorities by the radial placement beam that winds up, the space-load system that strut is connected to form with the hoop rope is set under the beam, be applicable to the roof structure of circular flat or elliptic plane.

As seen, adopting unidirectional string beam longitudinal stability rope or two-way string beam to form the space tension string beam structure, can effectively to solve a string Liangping face stable outward, but the node place connects complex structure, and prestressing force applies and have relatively high expectations, and causes the construction technology difficulty, the cost height.

The utility model content

Main purpose of the present utility model is to overcome deficiency of the prior art, provides a kind of and can effectively guarantee structural plan external stability energy, simple in structure is used for opening the spacing bindiny mechanism of string beam last quarter rope.For solving the problems of the technologies described above, solution of the present utility model is:

Provide a kind of for opening the spacing bindiny mechanism of string beam last quarter rope, comprise the beam that winds up, also comprise strut, drag-line, angle brace and roof purline, the upper end of described strut is hinged with the beam that winds up, the lower end of strut is connected with drag-line by node apparatus, fixedly connected with the two ends of the beam that winds up respectively in drag-line two ends after the stretch-draw, drag-line forms axisymmetric broken line; Described angle brace two ends are connected to node apparatus and roof purline.

As further improvement, described node apparatus is a kind of clamping rope device, comprise first cord clip, second cord clip, junction plate and bolt, junction plate is welded on first cord clip, junction plate is provided with for the pin shaft hole that connects angle brace or strut, first cord clip and second cord clip are corresponding in opposite directions to be placed and formation anchor clamps inner chamber, and correspondence respectively is provided with at least two bolts hole on first folder rope and second folder rope, is bolted to connection first folder rope and second folder rope.

Compared with prior art, the beneficial effects of the utility model are:

Keeping opening on the basis of string Liangping face structural system, adopt simple bindiny mechanism, effectively guaranteed structural plan external stability energy, improved the structure total bearing capacity, improved the scope of application that the string beam is opened on plane in the past, and engineering construction is simpler than space tension string beam structure, and speed of application is faster, and cost is lower.
