Description

A kind of big top

The utility model belongs to a kind of large-scale tent, especially for the big top of acrobatics and circus performance.

Existing large-scale big top body frame adopts by two columns and the single portal frame that crossbeam constitutes, utilize artificial capstan winch that tarpaulin is pulled to a high position, be connected with radial reinforcing rib on the tarpaulin, hound is set in the paulin,, is beneficial to the performance of high empty class program in order to guarantee that enough volumes are arranged in the paulin, portal frame then need raise, strengthen the spacing of two columns, both increased the deadweight of shelf, also make lifting difficulty more.Also have a kind of body frame of big top to adopt four columns, hang an elongated top skeleton by four column tops, its shortcoming is to adopt semi girder, and is stressed bad.

The purpose of this utility model provides a kind of lifting of being convenient to, and support is firm, is beneficial to the big top of high empty class program performance.

The purpose of this utility model is achieved through the following technical solutions.The support of big top is made up of gantry body frame, bearing diagonal post, limit support column and top skeleton, two gantry body frames are parallel to each other the opposite and put, top therebetween is lifted with the top skeleton of elongated, the crossbeam of top skeleton and two gantry body frames is perpendicular, a plurality of bearing diagonal posts are tilting in the outer ring of gantry body frame, the vertically upright outer ring that is located at the bearing diagonal post of a plurality of limits support column.The tarpaulin of big top is to enclose the single piece that tarpaulin is connected in sequence by top cloth, the big top cloth of main body and limit, top cloth is sleeved on the skeleton of top, the big top cloth of main body is opened to stretch-draw all around, the periphery limit support column support that tarpaulin joins is enclosed on itself and limit, the middle part of its hypotenuse is overlapped on the bearing diagonal post, the limit is enclosed tarpaulin and is enclosed the outside that is contained in the limit support column, constitutes the enclosure wall of big top.The big top cloth of main body is passed in four stands of two gantry body frames, and its top and two crossbeams are exposed at the outside of tarpaulin.Between two gantry body frames, between each gantry body frame and the ground and all socket between limit support column and the ground, to guarantee the stability of two gantry body frames with wire rope.

The top skeleton is formed by connecting by a minute segment frames.

Big top of the present utility model compared with prior art major advantage is: 1) rational in infrastructure, space in the bigger paulin is arranged, and especially increased a performance clog-free height in the paulin, can guarantee that high empty class program performs smoothly; 2) support is firm, and stressed good, the heavy burden ability is strong, the safety when helping ensureing performance; 3) easy accessibility, maintainability is good.

In order to further specify the structure of the utility model big top, reach embodiment below with reference to accompanying drawings and specifically describe.

Fig. 1 is the front half sectional view of the utility model big top;

Fig. 2 is the side half sectional view of big top shown in Figure 1;

Fig. 3 is the vertical view of this big top;

Fig. 4 is the elevation of top skeleton;

Fig. 5 is the lateral view of top shown in Figure 4 skeleton;

Fig. 6 is the vertical view of top shown in Figure 4 skeleton.

Referring to Fig. 1 to Fig. 3, among the figure, 1 is gantry body frame, 2 is the bearing diagonal post, and 3 is the limit support column, and 4 is the top skeleton, 5 is top cloth, and 6 is the big top cloth of main body, and 7 for enclosing tarpaulin in the limit, 8 is body frame, and 9 is crossbeam, and 10 are the horizontal wire rope that draws of body frame, 11 are the lifting wire rope, 12 is body frame oblique rollering steel silk rope, and 13 is side column oblique rollering steel silk rope, and 14 are the pricker nail.The support of big top is the supporting member of tarpaulin, and it is made up of two gantry body frames 1, bearing diagonal post 2, limit support column 3 and top skeleton 4, and two gantry body frames 1 opposite that is parallel to each other is provided with, and the cross section in the space that is surrounded by its four stands 8 is square.The big top cloth 6 of main body is performance paulins, adopt round bottom, oval roof construction, its upper and lower limit is enclosed tarpaulin 7 with top cloth 5 and limit respectively and is connected, on the border at big top cloth 6 hypotenuses of main body 1/2 place, be laid with tilting bearing diagonal post 2 equably, be used to support tarpaulin 6, prevent that big top cloth 6 linings of main body are sagging.For easy to maintenance, the big top cloth 6 of main body can be sewed up by the multi-disc tarpaulin and form, and suture is (not shown) radially.The big top cloth of main body 6 and limit are enclosed on the circle at the periphery place that tarpaulin 7 joins and are provided with limit support column 3 equably, are used to support tarpaulin.The limit is enclosed tarpaulin 7 and is enclosed the outside that is contained in limit support column 3, forms enclosure wall, and the limit is enclosed tarpaulin 7 and set out the ABC of (not shown).The tarpaulin of this big top forms to the PVC of fabricbase material with twin shaft.The two ends of top skeleton 4 are lifted on two crossbeams 9 by two lifting wire rope 11 respectively, are positioned at two crossbeams, 9 middle belows and perpendicular with two crossbeams 9.The big top cloth 6 top linings of main body are passed in four stands 8 of two gantry body frames 1, and its top and crossbeam 9 all expose to tarpaulin.Tarpaulin outside at big top, socket the horizontal wire rope 10 that draws between the two ends of two crossbeams 9, respectively socket two body frame oblique rollering steel silk ropes 12 between the two ends of two crossbeams 9 and the ground, all socket side column oblique rollering steel silk rope 13 between the top of each limit support column 3 and the ground, the wire rope that links to each other with ground adopts pricker nail 14 to fix on the ground, make that the overall performance of this big top is good, solid and reliable.The stand 8 of gantry body frame 1 and crossbeam 9, top skeleton 4 all adopt frame construction, and the cross section of stand 8 frameworks is a square, and the cross section of crossbeam 9 frameworks is a rectangle, and this structure is convenient in framework inside relative assembly is set, as hanging apparatus.It is leg-of-mutton frame construction that bearing diagonal post 2 adopts cross section, also can adopt tubular structure, and limit support column 3 adopts tubular structure.

Referring to Fig. 4 to Fig. 6, among the figure, 15 is skeleton top, and 16 is the skeleton bottom, and 17 is the skeleton side.Top skeleton 4 is the supporting member of top cloth 5, is again the primary structure member of lifting program stage property, and it is the elongated structure that is vertically linked to each other and form by three segment frames, and this segmental structure helps maintenance and transportation.Top skeleton 4 adopts rational frame construction, the cross section on its skeleton top 15 is a triangle, the cross section of skeleton bottom 16 is the isosceles trapezoid of interior angle approximate right angle, because there is certain height skeleton side 17, the two sides that are sleeved on the top cloth 5 of 17 outsides, skeleton side offer the vent window (not shown), can improve the environment of performance, and rainwater can not flow into big top influence performance yet when rainy.
