Abstract
The utility model discloses an engineering folding bridge ladder, and relates to the building field, in particular to an engineering bridge ladder structure. The engineering folding bridge ladder comprises a plurality of sections of metal supports. Each section of metal support comprises two big-end-down guard bars and a pedal, the lower ends of every two guard bars are connected through one pedal, and every two adjacent pedals are connected through a hinge. A connecting rod is hinged to the opposite sides of the upper ends of every two adjacent guard bars, every two adjacent connecting rods are hinged through a connecting shaft, each connecting shaft is further connected with a telescopic shaft, and the other end of each telescopic shaft is connected with the corresponding hinge. The two sides of each section of metal support in the width direction are respectively and fixedly connected with a stiffener mounting groove. After the engineering folding bridge ladder is unfolded, metal bars or reinforcing steel bars of different lengths can be inserted into fixing grooves for fixing according to needs, the engineering folding bridge ladder can be used as a bridge or a ladder, for the reason that the folding bridge ladder is unfolded in the using process and is folded after being used, transferring is convenient, manual work and time are saved, and the ladder can also be placed and taken conveniently.
Description
Technical field
The utility model relates to building field, relates in particular to the structure of engineering bridge ladder.
Background technology
In prior art, often can use span more greatly or highly higher engineering construction in building operations and decorations, solution is done exactly crane span structure or sets up scaffold conventionally.So not only heavy also waste of method complex engineering material a large amount of manually also wasted the valuable time to processing accident simultaneously, is inconvenient to carry and be inconvenient to deposit wait factors all to having brought inconvenient in daily construction and having taken the space of lot of materials stacking.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of engineering volume bridge ladder is provided, make in daily work progress convenient, convenient when carrying and depositing.
The purpose of this utility model is achieved in that a kind of engineering volume bridge ladder, comprise some joint metallic supports, every joint metallic support comprises respectively two up-small and down-big guardrails and a pedal, the lower end of two guardrails connects by pedal, adjacent two pedals are connected through the hinge respectively, the upper end opposite sides of adjacent two guardrails bar that is articulated and connected respectively, and adjacent two connecting rods are hinged by connecting axle, on connecting axle, also connect telescopic shaft, the other end of telescopic shaft and corresponding chain connection; The both sides of described every joint metallic support width are fixedly connected with respectively bracing piece mounting groove.
Long 12 meters (can adjust as required the length and width of metal frame) of the utility model, consists of eight joint metallic supports, can in holddown groove, insert as required the metal bar of different length or reinforcing bar and be fixed and can be used as bridge or ladder uses after expansion.Metallic support, by chain connection, is looked for neutral gear to insert and mark time during ascend operation in support junction after only front end bracing piece mounting groove need being connected by bracing piece.Assist staff on-site high fall low, just like folding stair.For large span ater-casting, while shuttling back and forth between high-rise building or for the treatment of accident, be also suitable effectively.Volume bridge ladder is opened the used time, is finished volume and gathers into folds, and convenient transfer, has not only saved artificial, time and be also convenient to put and take.

The specific embodiment
As Figure 1-4, for engineering volume bridge ladder, comprise eight joint metallic supports 5, the both sides of every joint metallic support 5 widths are fixedly connected with respectively bracing piece mounting groove 6.Every joint metallic support 5 comprises respectively two up-small and down-big guardrail 5-1 and a pedal 5-2, the lower end of two guardrail 5-1 connects by pedal 5-2, adjacent two pedal 5-2 connect by hinge 4 respectively, the upper end opposite sides of adjacent two the guardrail 5-1 bar 1 that is articulated and connected respectively, adjacent two connecting rods 1 are hinged by connecting axle 2, on connecting axle 2, also connect telescopic shaft 3, the other end of telescopic shaft 3 is connected with corresponding hinge 4.After launching, with a longer bracing piece (metal bar or reinforcing bar), insert in bracing piece mounting groove 6, just form bridge-type, also increase the fastness while trampling simultaneously.
As shown in Figure 5, end is rolled up and folded, angulation, all the other expansion are also inserted in bracing piece mounting groove 6 with a shorter bracing piece (metal bar or reinforcing bar), just form folding stair.
