Abstract
The utility model discloses an attached lifting scaffold bottom truss. The attached lifting scaffold bottom truss comprises vertical rods and diagonal web members; the plurality of vertical rods are vertically arranged in a mode of being divided into an internal layer and an external layer; the truss also comprises an upper horizontal walking channel plate and a lower horizontal walking channel plate; the upper horizontal walking channel plate and the lower horizontal walking channel plate are connected with the vertical rods through fastening parts; the two internal layer vertical rods, the two external layer opposite vertical rods, the upper horizontal walking channel plate and the lower horizontal walking channel plate form into a unit cuboid framework; the plurality of diagonal web chambers are arranged between the internal layer vertical rods and the external layer vertical rods of the unit cuboid framework; upper ends and lower ends of the diagonal web chambers are fixedly connected with the upper horizontal walking channel plate and the lower horizontal walking channel plate. The attached lifting scaffold bottom truss is firm in structure and a channel base plate is not required to be arranged additionally.
Description
Technical field
The utility model belongs to the supporting member technical field of scaffold.
Background technology
Attached lift scaffold in building operations, refers to and sets up certain altitude and be attached in engineering structures, relies on jacking equipment and the device of self, can successively climb or decline with engineering structures, has the external scaffolding of overturn-preventing, anti-falling function.
Existing attachment type raise scaffold mainly consists of bottom truss, main frame, guide rail, attachment support and falling proof device etc., and main frame is arranged on truss upper end, bottom.Bottom truss is divided into inside and outside two, every is the rectangular frame consisting of fastener or other securing members cross bar (pipe) and vertical rod (pipe), between inside and outside two, by vertical pole (pipe), also connect into upper and lower rectangle frame, in rectangular frame, be fastened with the diagonal web member (pipe) for stiffening frame.At the construction field (site), set up after the erection truss of bottom, need in the lower rectangle frame of bottom truss, lay limp, be used as walking passage.
The shortcoming of existing attaching scaffold is: 1. the link area of vertical pole is less, be subject to load after unit pressure large, vertical pole link is prone to fracture, the phenomenon such as loosening; 2. need to lay in addition walkway board, install comparatively loaded down with trivial details.
Utility model content
The utility model is intended to provide a kind of sound construction, simultaneously without the attachment type raise scaffold bottom truss of laying separately walkway board.
The purpose of this utility model can reach by following measures: attachment type raise scaffold bottom truss, comprise vertical rod, diagonal web member, some vertical rods divide inside and outside two-layer vertical arrangement, the upper and lower walkway board that also comprises horizontal parallel, upper and lower walkway board is connected with vertical rod by securing member, two vertical rods of internal layer, outer relative two vertical rods, upper walkway board and lower walkway board Component units cuboid framework; Described some diagonal web members are between the internal layer vertical rod of unit cuboid framework and between outer vertical rod, and the upper and lower end of diagonal web member is affixed with upper and lower walkway board respectively.
Technique scheme difference with the prior art is: unit cuboid framework consists of vertical rod, diagonal web member and walkway board, compare with traditional vertical pole, the load that vertical rod, diagonal web member apply can be delivered on whole walkway board, because the area of walkway board is larger, the unit load of walkway board is less, makes whole bottom trussed construction more firm; In addition, lower walkway board can be used as channel base plate, has saved the process of another paving channel base plate.The utility model, by making traditional rod (pipe) and being connected of bar (pipe) being connected of bar (pipe) and plate into, has reduced installation difficulty, and makes bottom truss more firm.
Further, between the internal layer vertical rod of described unit cuboid framework and be respectively arranged with the diagonal web member of two mirror image symmetries between outer vertical rod, the structure of the unit's of making cuboid framework is more firm.
Further, the upper and lower end of described diagonal web member is homalocephalus, and upper and lower walkway board is provided with some bolts hole, and the homalocephalus of diagonal web member and walkway board are affixed by bolt; The lower end of the same layer diagonal web member of unit cuboid framework is mutually close, and upper end mutually away from, make lower walkway board and diagonal web member form equilateral triangle structure, increase the bearing strength of bottom truss.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model attachment type raise scaffold bottom truss embodiment.
The specific embodiment
As shown in Figure 1: attachment type raise scaffold bottom truss, the walkway board that comprises vertical rod 1, diagonal web member 3 and steel, walkway board comprises upper walkway board 21, the lower walkway board 22 of horizontal parallel, some vertical rods 1 are divided into inside and outside two-layer vertical arrangement, at upper walkway board 21, lower walkway board 22, by flange, are connected with vertical rod 1.
Two vertical rods 1 of internal layer and outer two piece vertical rods 1 relative to them and upper walkway board 21, lower walkway board 22 Component units cuboid frameworks, several unit cuboid frameworks form whole bottom truss.
Two diagonal web members 3 are all installed between the internal layer vertical rod 1 of each unit cuboid frame and between outer vertical rod 1, on upper walkway board 21, lower walkway board 22, have some bolts hole, the upper and lower end of diagonal web member 3 is homalocephalus, and upper and lower homalocephalus is connected with upper walkway board 21, lower walkway board 22 bolts respectively.In each unit cuboid framework, two diagonal web members 3 that are positioned at same layer (internal layer or skin) are mirror image symmetry, the lower end of two diagonal web members 3 mutually close, upper end mutually away from.
The foregoing is only the detailed description of the utility model preferred embodiment, be not used for limiting the utility model, the embodiment of all similar variations of doing according to creation spirit of the present utility model, all should be contained among the utility model protection domain.
Claims (3)
