Abstract
The utility model discloses a combined truss space dome which is formed by intercrossing a plurality of trusses; the trusses are intercrossed to form a round; adjacent trusses are connected by loop cables; reinforcement devices are arranged at intercrossed upper nodes and lower nodes of the trusses; the main body structure of each truss is a wooden structure; the reinforcement devices are metal structures; the reinforcement device with the metal structure is arranged at the node connected between each truss and the loop cable. The combined truss space dome has the beneficial effects that the structure is novel, the truss-cable dome combined space structural mode and the steel-wood structural material combined mode are adopted, the problems of large steel consumption amount and higher construction cost due to the full adoption of steel structures are solved, and the problem that the use is influenced as the nodes in the steel-wood combined structure are infirm is solved.
Description
Technical field
The utility model relates to a kind of space dome, particularly a kind of composite roof truss space dome.
Background technology
At present, long-span space roof structure has prestressed reinforced concrete construction roof system, greatly across steel structural roof, greatly across steel and wood composite structure roof system etc., though it is high to have intensity across steel structural roof greatly, anti-seismic performance is good, the advantages such as energy-conserving and environment-protective, but steel work steel using amount is large, cost is higher, using wooden construction as agent structure across steel and wood composite structure roof system greatly, steel work is interspersed in the stability that ensures agent structure among wooden construction as supplementary structure, rod part is connected with the node of steel structural rod piece and the processing of many rod part connected nodes is a large difficult point of steel and wood composite structure roof design.
Summary of the invention
The purpose of this utility model is in order to solve existing greatly large across steel structural roof steel using amount, a kind of composite roof truss space dome that cost provides compared with the problem of high and the bad processing of node that steel and wood composite structure roof system connects.
Composite roof truss described in the utility model space dome is intersected and is formed by several product truss, and number product truss intersects to be become one roundly, between adjacent truss, is connected by strop, and upper node and lower node place that number product truss intersects are provided with bracing means.
The agent structure of truss is wooden construction.
Bracing means is metal construction.
The Nodes that every product truss is connected with strop is provided with the bracing means of metal construction.
Design principle of the present utility model:
The agent structure of truss is wooden construction, and wooden rod node adopts hardware to reinforce, and specific design is: many rod part connected nodes adopt the tapered steel plate of double-layer circular, circular steel plate to fix, and with bolt connection, reduce roof system design of node difficulty; Rod part is as compressed member, tension wood rod member both sides add steel band, taking steel band as main tensional element, can reduce the sectional dimension of rod part, make full use of the advantage of wooden construction and steel structure material performance, for ensureing the globality of space structures, strop place steel band overlaps a segment length at Nodes, and roof system all adopts environment-friendly materials, be mainly applicable to China's Residential Buildings in Small Town, large span spatial structure building.
The beneficial effects of the utility model:
Novel structure, adopt truss-rope dome composite space form of structure and steel-wooden construction material complex form, thoroughly having solved is all the problem that steel work steel using amount is large, cost is higher, and has solved the insecure and problem that impact is used of Nodes in steel and wood composite structure.

Detailed description of the invention
Refer to shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4:
Composite roof truss described in the utility model space dome is intersected and is formed by four product truss 1, and four product truss 1 intersect to be become one roundly, between adjacent truss 1, is connected by strop 2, and upper node 3 and lower node 4 places that four product truss 1 intersect are provided with bracing means 5.
The agent structure of truss 1 is wooden construction.
Bracing means 5 is metal construction.
Node 6 places that every product truss 1 is connected with strop 2 are provided with the bracing means 7 of metal construction.
Design principle of the present utility model:
The agent structure of truss 1 is wooden construction, and wooden rod node adopts hardware to reinforce, and specific design is: many rod part connected nodes adopt the tapered steel plate of double-layer circular, circular steel plate to fix, and with bolt connection, reduce roof system design of node difficulty; Rod part is as compressed member, tension wood rod member both sides add steel band, taking steel band as main tensional element, can reduce the sectional dimension of rod part, make full use of the advantage of wooden construction and steel structure material performance, for ensureing the globality of space structures, strop 2 place's steel bands overlap a segment length at node 6 places, and roof system all adopts environment-friendly materials, be mainly applicable to China's Residential Buildings in Small Town, large span spatial structure building.
