Abstract

The utility model provides a novel inner strengthened triangular prism which has long length, high strength and good windproof performance. The novel inner strengthened triangular prism comprises a hollow triangular prism body formed by integrally connecting three arrises. An inner strengthened body integrally connected with the triangular prism body is arranged on the inner side of the triangular prism body. The inner strengthened body is a hollow triangle body. Top points of the triangle body are respectively connected with the arrises of the triangular prism. The novel inner strengthened triangular prism can be applied to advertising pictures with large layout, and has good effect, high utilization rate and wide market prospect.

Description

A kind of novel interior triangular prism of strengthening

Technical field

The utility model relates to a kind of device of three surface-turning advertising placard, relates in particular to a kind of novel interior triangular prism of strengthening.

Background technology

Existing three surface-turning advertising placard; Its space of a whole page is to be formed by some triangular prisms and registration; And drive the triangular prism upset through the gear train that the triangular prism lower end is provided with; Make three surface-turning advertising placard contrast single face billboard, have same area and can represent three different advertisement pictures, higher use value is arranged in prime locations such as the high market of rent now, squares.By the three surface-turning advertising placard space of a whole page that tens of triangular prisms rearrange, its front face area has tens square metres, particularly will receive tens tons pressure in the typhoon at strong wind.Because triangular prism is hollow structure; So the length of triangular prism can not be done oversizely, otherwise the easy flexural deformation of triangular prism, wind resistance is not enough; The phenomenon of collision each other takes place when causing the triangular prism upset; Damage three surface-turning advertising placard, even can cause triangular prism to drop, to passerby's life generation serious threat.

Moreover, receiving the influence of production technology level, the length of triangular prism can not be done oversizely, at this moment requires bigger advertisement picture for the space of a whole page, can't use, and is restricting the application of three surface-turning advertising placard.In order to address this problem, each three face turns over manufacturer and is devoted to study and three faces is turned over can be applied to the bigger advertisement picture of various space of a whole page requirements better.Occurred a kind of superelevation web member that is used for three surface-turning advertising placard on the market, this superelevation web member makes triangular prism pass through connecting method and forms more significantly advertisement picture of the space of a whole page as the strong point of upper and lower triangular prism.But this superelevation web member can make and form a gap between the upper and lower triangular prism, causes the advertisement picture middle part to form mark of break, influences the aesthetic feeling of view picture advertisement picture.In addition, also have the arris through the thickening triangular prism, perhaps in the inboard of triangular prism arris reinforcement longitudinally is set, but intensity is still lower, the polar moment of inertia in cross section is still less, receives the influence of strong wind, still can occur bending and deformation.

Summary of the invention

Therefore, in order to solve the problem of above-mentioned existence, the utility model provides that a kind of length is longer, intensity is higher, wind loading rating is strengthened triangular prism in better novel.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of novel interior triangular prism of strengthening, comprise the hollow triangular prism body that links to each other and form by three arris one, and said triangular prism body inboard is provided with the interior intensive aspect that links to each other with triangular prism body one.

Preferably, said interior intensive aspect is hollow triangle body, and each summit of triangle body links to each other with the arris of triangular prism respectively.

Through adopting preceding technical scheme, the beneficial effect of the utility model is following: the utility model is through being provided with a leg-of-mutton intensive aspect, because each summit of intensive aspect links to each other with triangular prism is inboard respectively in the triangular prism inboard; One-piece construction by aluminum alloy materials through extrusion modling; Be integrally formed structure, not only improved the triangular prism integral intensity, increased the polar moment of inertia in cross section; Improved bending strength, reduced flexural deformation, and wind resistance is stronger.The utility model is compared with original triangular prism, except intensity better, biggest advantage is that length can be done longlyer than original triangular prism; Can reach more than 8 meters or 8 meters; And can be not long because of length, and cause flexural deformation, be applied to the advertisement of the bigger space of a whole page; Better effects if, utilization factor are higher, have vast market prospect.

Description of drawings

Fig. 1 is the cross-sectional structure synoptic diagram of the utility model.

Embodiment

Combine accompanying drawing and embodiment that the utility model further is elaborated at present.

With reference to figure 1; The utility model embodiment discloses a kind of novel interior triangular prism of strengthening; Comprise the hollow triangular prism body that is linked to each other and formed by three arris 1 one, said triangular prism body inboard is provided with the interior intensive aspect 2 that links to each other with triangular prism body one, and said interior intensive aspect 2 is hollow triangle body; The thickness on each limit of triangle body is 1.4mm, and each summit of triangle body links to each other with arris 1 one of triangular prism respectively.The triangular prism of the utility model through extrusion modling, is integrally formed structure by aluminum alloy materials, in extrusion process, because the interior intensive aspect of the triangle that has built-in one to link to each other after triangular prism reaches certain-length, also is not easy to produce crooked phenomenon; When practice, triangular prism can be made more than 8 meters or 8 meters long, is applicable to the advertisement of the bigger space of a whole page, better effects if.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; Concrete this technical scheme method of realization and approach are a lot; The above only is the preferred implementation of the utility model, but the those skilled in the art should be understood that in the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.

Claims (2)

1. the novel interior triangular prism of strengthening comprises the hollow triangular prism body that is linked to each other and formed by three arris one, and it is characterized in that: said triangular prism body inboard is provided with the interior intensive aspect that links to each other with triangular prism body one.

2. the novel interior triangular prism of strengthening according to claim 1, it is characterized in that: intensive aspect is hollow triangle body in said, and each summit of triangle body links to each other with the arris of triangular prism respectively.
