Abstract
The utility model discloses a truss type keel for a stand seat. The truss type keel comprises a supporting frame, wherein the supporting frame is of a truss structure and comprises a first chord rod and a second chord rod. The first chord rod is slantly arranged and is parallel to the second chord rod, reinforcing pipes are arranged between the second chord rod and the first chord rod, the upper end of the second chord rod is connected with the first chord rod through a first connection rod, the lower end of the second chord rod is connected with the first chord rod through a second connection rod, a plurality of steps are arranged on the first chord rod, and the steps are formed by perpendicularly-arranged longitudinal pipes and horizontally-arranged transverse pipes. The truss type keel for the stand seat is simple in structure and easy to achieve, the supporting frame is of the truss structure, and the truss type keel for the stand seat is light in self weight, large in rigidity, reasonable in structure, high in bearing force, rapid and convenient to use, economical and practical.
Description
Technical field
The utility model relates to a kind of truss-like grandstand seat keel.
Background technology
At present, in daily life, often need in indoor or outdoor stadiums, hold some public activities, be typically provided with some fixing grandstands in these stadiums and watch activity for spectators.Seat on grandstand and the grandstand is supported by keel, existing grandstand seat keel, and its bracing frame is right-angle structure, is welded to connect step on it, and this kind structure exists weight large, and rigidity is little, the problem of low bearing capacity.
The utility model content
The purpose of this utility model is for the problems referred to above, and a kind of truss-like grandstand seat keel are provided, and large with keel weight to solve existing grandstand seat, rigidity is little, the problem of low bearing capacity.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of truss-like grandstand seat keel, comprise bracing frame, support frame as described above is trussed construction, it comprises the first chord member and the second chord member, described the first chord member is obliquely installed, and it parallels with the second chord member, be provided with reinforced pipe between described the second chord member and the first chord member, and the upper end of the second chord member links to each other with the first chord member by first connecting rod, its lower end links to each other with the first chord member by second connecting rod, be provided with a plurality of steps on described the first chord member, described step is made of vertically disposed longitudinal tubule (L tubule) and horizontally disposed transverse tube.
Further, support frame as described above is the parallel chord truss structure, and the two ends of its first chord member are welded to connect with first connecting rod, second connecting rod respectively, and the two ends of the second chord member are welded to connect with first connecting rod, second connecting rod respectively.
Further, described step is welded to connect on the first chord member.
Further, described step is three.
Further, vertically be provided with inner sleeve on the described first connecting rod, the longitudinal tubule (L tubule) internal diameter of the external diameter of described inner sleeve and step is complementary.
The beneficial effects of the utility model are, described truss-like grandstand seat is simple with keel structure, are easy to realize, its bracing frame adopts trussed construction, and are not only large from heavy and light, rigidity, and rational in infrastructure, bearing capacity is high, and is easy to use, quick, economical and practical.
Description of drawings
Fig. 1 is the structural representation that keel are used at the utility model truss-like grandstand seat.
Among the figure:
