Abstract
The utility model provides a ladder-type bridge frame, comprising a plurality of ladder rolls and ladder sides arranged at two sides; the head end and the tail end of each ladder roll are connected with the ladder side at one side respectively; the connecting places of the ladder rolls and the ladder sides are provided with self-tapping screw holes; and the ladder sides are provided with holes corresponding to the self-tapping screw holes. Compared with the prior art, the ladder-type bridge frame is extremely simple and convenient for construction and can be completed by self-tapping screws only.
Description
Technical field
The utility model belongs to for the distribution technique field, specifically is a kind of ladder type crane span structure.
Background technology
In the prior art, the ladder type crane span structure is being used often aspect distribution.Traditional ladder type crane span structure is in the time of the assembling construction, because the dimensional requirement of the terraced limit assembling of terraced rod and both sides is relative higher, so there is constructional difficulties, connection fittings require problems such as many
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of new ladder type crane span structure, concrete technical scheme is as follows:
A kind of ladder type crane span structure comprises the terraced limit of a plurality of terraced rods and both sides, and the two ends end to end of each terraced rod connect the terraced limit of a side respectively.Described terraced rod and junction, terraced limit are provided with the tapping screw hole, and terraced limit is provided with the hole corresponding with the tapping screw hole.
The shape of cross section of described terraced rod is " mountain " font, and described tapping screw hole is on the both sides of " mountain " font.
Described tapping screw hole is located at inner edge on the both sides of " mountain " font of terraced rod.
The cross section in described tapping screw hole is " C " font.
Three limits of " mountain " font of described terraced rod cross section are provided with the limit vertical with described limit, constitute reinforcement.
Described terraced rod be aluminium section.
Three limits, reinforcement and the tapping screw hole of the cross section of described terraced rod " mountain " font are overall structures.
Also comprise guard shield, guard shield is connected with the terraced limit of both sides.
Compared with prior art, very easy when the utility model is used to construct, only need to finish with tapping screw.The hole wall in the reinforcement on the terraced in addition rod, " C " font tapping screw hole and the shape of cross section of terraced rod all help strengthening the intensity of terraced rod.Because terraced rod cross section adopts the structure of this programme, so terraced rod can adopt the make-up machine one-shot forming.
Description of drawings
Fig. 1 is the assembling schematic diagram of embodiment;
Fig. 2 is the terraced rod cross sectional representation of embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
A kind of ladder type crane span structure comprises the terraced limit 2,3 of a plurality of terraced rods 1 and both sides, and the two ends end to end of each terraced rod 1 connect the terraced limit 2 or 3 of a side respectively.Described terraced rod 1 is provided with tapping screw hole 6 with 2,3 junctions, terraced limit, and terraced limit 2 and 3 is provided with the hole corresponding with tapping screw hole 6.
The shape of cross section of described terraced rod 1 is " mountain " font, described tapping screw hole 6 on the both sides of " mountain " font, concrete inner edge on the both sides of " mountain " of terraced rod font.The cross section in described tapping screw hole 6 is " C " fonts.
Three limits of " mountain " font of described terraced rod 1 cross section are provided with the limit vertical with described limit 7, constitute reinforcement.
Described terraced rod 1 be aluminium section.
Three limits, reinforcement 7 and the tapping screw hole 6 of the cross section of described terraced rod 1 " mountain " font are overall structures.
Also comprise guard shield 4, guard shield 4 is connected with the terraced limit 2,3 of both sides.
