Description

Dismountable large-span prestressed integral tension awning
Technical field
This utility model relates to a kind of long span building canopy structure.
Background technology
The stock ground of present stage national environmental protection policy requirements air storage, coal yard etc. must be closed, and part big city incity steel mill and power plant face environmental protection pressure and are likely to resettlement reconstruction, in period before strange land rebuilds, its stock ground also should be closed, and realizes the architectural structure system of super-span while being therefore badly in need of a kind of detachable certain reconstruction.
For the exploitation of outdoor coal yard and mining site, the outdoor archaeology place of large area etc. all needs a kind of large span detachable and can the building rebuild of strange land.Conventional large-span steel adopts the rigid structure such as steel truss, Elements of Space Grid Truss, is connected by welding, does not have the probability that dismounting is rebuild with strange land as permanent structure.The temporary building of the most of little span of building that existing detachable strange land rebuilds or tent, span is little, use narrow range, dismounting inconvenience.
Utility model content
This utility model provides a kind of dismountable large-span prestressed integral tension awning, solve existing long span building canopy structure and not there is dismounting and the technical problem of strange land reconstruction probability, and super-span cannot be realized, dismantle the technical problem inconvenient, cost is high.
This utility model solves its technical problem and be the technical scheme is that
This dismountable large-span prestressed integral tension awning, pin connector between the integral tension cable truss unit being arranged in parallel including two more than Pin, adjacent two Pin integral tension cable truss cell nodes, and it is laid on the film between valley cable and the notochord of integral tension cable truss unit;
Described integral tension cable truss unit is by one group of notochord, two groups of valley cables, sub-truss, oblique cord outside end, interior oblique cord, end batter post, horizontal brace composition on batter post, the triangle space formed between described one group of notochord and two groups of valley cables is connected by sub-truss, integral tension cable truss unit two ends are respectively arranged with on two end batter posts and a batter post horizontal brace and connect and form inverted triangle, the base angle that one group of notochord end downwardly extends with above-mentioned inverted triangle is connected, two drift angles that two groups of valley cable ends upwardly extend with above-mentioned inverted triangle are connected, two drift angles of above-mentioned inverted triangle inwardly and are connected to interior oblique cord between notochord end, two drift angles of above-mentioned inverted triangle are to being externally connected with outside end oblique cord;
Described pin connector is made up of two semispherical joints, two cord clip nodes, bearing pin and connecting plate, and described semispherical joint is made up of hemisphere and the hemisphere otic placode that is connected on hemisphere, and cord clip node is made up of cord clip, train wheel bridge, lower plate and cord clip otic placode;The described connecting plate left and right sides is connected by the cord clip otic placode of two the cord clip node sides in bearing pin and left and right respectively, and the cord clip otic placode of cord clip node opposite side is connected with the hemisphere otic placode on semispherical joint by bearing pin again;
It is fixing that sub-truss end on described integral tension cable truss unit is welded on the hemisphere of semispherical joint, and valley cable (12) is arranged on cord clip, and is fixed by the bolt-locking on train wheel bridge and lower plate.
The triangular truss that described sub-truss is space spindle-shaped truss or single pole connects into.
Described notochord, valley cable, end batter post are all articulated and connected with basis.
Described notochord or valley cable are by the Suo Zucheng of more than two.
Outside described notochord, valley cable, end, oblique cord and interior oblique cord are high strength steel drag-line, high-strength chemical fiber rope or carbon fiber rope.
