Abstract
The invention discloses an irregular self-stress tension integral structure which comprises three inclined and crossed compression rods, wherein ball nodes are fixedly installed at both ends of each compression rod; three transverse stay ropes are mutually connected between the ball nodes at the upper layer and the lower layer of the three inclined and crossed compression rods respectively; and three vertical stay ropes are connected between the ball nodes at the upper end and the lower end of each compression rod. The invention has more reasonable structure, reduces weight under the premise of ensuring that the integral strength is not changed and saves the manufacture cost.
Description
Technical field
The present invention relates to irregular self-stress tension integral structure.
Background technology
Irregular self-stress tension integral structure is one of research topic of forefront, structure field, current international space, and it is a kind of stable self equilibrium systems of being made up of discontinuous depression bar and continuous drag-line; This structure by from stress to improve structural stress state, improved supporting capacity, simultaneously, a large amount of uses of high strength wire rope are compared with widely used member structure in the construction now, have saved great deal of steel, remarkable in economical benefits has broad application prospects.
Summary of the invention
The purpose of this invention is to provide a kind of irregular self-stress tension integral structure, structure is more reasonable, is guaranteeing that cost of manufacture has been saved in weight saving under the constant situation of bulk strength.
Technical scheme of the present invention is as follows:
Irregular self-stress tension integral structure, include three depression bars that tilt to intersect, the two ends of depression bar are installed with ball node, interconnect three horizontal drag-lines respectively between the ball node of described three upper and lower layers of depression bar that tilt to intersect, be connected with three vertical drag-lines between the ball node of the upper and lower end of each depression bar.
Irregular self-stress tension integral structure of the present invention is assembled continuously by some monomer models, and each monomer model mainly is made up of depression bar, drag-line and node, and typical monomer model is made up of 3 depression bars, 9 drag-lines and 6 nodes.Depression bar is born pressure in model, the steel pipe of depression bar material selection routine is as Q235 or Q345; Drag-line is the tensional element in the model, adopts the 1*19 round-strand rope, and wire rope nominal tensile strength is 1570MPa; Node is selected the ball node form of space grid structure for use, and ball is the steel medicine ball, and material is the 45# steel.Suo Yuqiu is connected to a kind of self-stress pre-tighten cable-rod structure.The assembly unit employing between monomer model and the monomer model and the identical construction technology of assembly unit of monomer model self.
Structure of the present invention is more reasonable, is guaranteeing that cost of manufacture has been saved in weight saving under the constant situation of bulk strength.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, irregular self-stress tension integral structure, include three depression bars 1 that tilt to intersect, the two ends of depression bar 1 are installed with ball node 2, interconnect three horizontal drag-lines 3 respectively between the ball node 2 of three depression bar 1 upper and lower layers that tilt to intersect, be connected with three vertical drag-lines 4 between the ball node of the upper and lower end of each depression bar.
With the monomer model is example, and the mounting process process is as follows:
1, drag-line is connected with tensioning apparatus
When drag-line and tensioning apparatus are installed, must cleaning connection of thread dirt, tensioning apparatus and rope anchor head place slide key can not between tension can not be installed, cause tensioning apparatus to slide.
2, depression bar and ball node are installed
Depression bar and ball node are put according to each member spatial relationship after installing, and are convenient to next step process operations.
3, lower floor's drag-line is installed
During installation,, each jump stay fixed end and ball node are installed and fixed according to the drawing sign.
4, the upper strata drag-line is installed
Erect depression bar upper strata ball node to the installation site, be connected and fixed upper strata cable stretching end.
5, vertical drag-line is installed
Vertical drag-line is installed as the installation final step, connects each rope fixed end earlier, connects the tension side again, notes symmetrical construction during construction how much, and stretch-draw length is identical with lower floor rope bar installation.
6, preliminary stretch-draw
After installing, check drag-line and the ball node junction position that whether is not connected firmly, inspection finishes, carry out whole unit stretch-draw, adopt during stretch-draw to be how much symmetrical stretch-draw, the space coordinates of rope length and each node is measured on stretch-draw limit, limit, and stretch-draw first is 30% of final stretch-draw value.
7, drag-line length and ball node coordinate are checked
After the stretch-draw, rope length and each node coordinate are carried out immediately monitoring first, and record data.
8, two times tensioning
Repeating step 6,7 is stretched to final value of thrust.
Claims (1)
1. irregular self-stress tension integral structure, it is characterized in that: include three depression bars that tilt to intersect, the two ends of depression bar are installed with ball node, interconnect three horizontal drag-lines respectively between the ball node of described three upper and lower layers of depression bar that tilt to intersect, be connected with three vertical drag-lines between the ball node of the upper and lower end of each depression bar.
