Abstract
The utility model discloses a tool-type combined steel ladder which comprises a protective barrier, a stand rod and a stair landing. The tool-type combined steel ladder is characterized by further comprising ladder beams, a flier and a fixing angle iron. The angle iron is of an arc shape, and is fixed with a plurality of layers of steel discs with different angels. The fixing angle iron is fixed with four ladder beams. The lower end of the flier is fixed with the four ladder beams, and the upper end of the flier is clamped into the steel discs of the fixing angle iron. The stand rod penetrates through the filer and is fixed with the flier through a nut. The lower end of the stand rod is fixed with a screw rod. A through hole in the middle of the flier is used for fixing the screw rod. The tool-type combined steel ladder is reasonable in structural design. The problems that setting up and dismantling of a common ladder stand take time and require a lot of labor, and subsequent construction follow-up is affected are effectively solved, and at the same time construction residual materials can be effectively utilized.
Description
Technical field
The utility model relates to a kind of tool-type combination steel ladder.
Background technology
In operation process, for making things convenient for about the personnel, all need set up cat ladder, because conventional cat ladder time-consuming taking a lot of work when setting up and dismantling, and material usage is larger, and economy, time are all unreasonable.
The utility model content
Technical problem to be solved in the utility model provides a kind of tool-type combination steel ladder, has solved the problems referred to above.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of tool-type combination steel ladder comprises guard rail and vertical rod and half space, it is characterized in that: also comprise terraced beam, step plate and fixing angle steel; Described fixedly angle steel is arc, the fixing multilayer steel disc of different angles on it, and described fixedly angle steel and four terraced beams are fixed; Step plate lower end and terraced beam are fixed, and step plate upper end sticks in the steel disc of fixing angle steel, and vertical rod is to wearing step plate and fixing with nut.
Perforation is used for fixing with this screw rod in the middle of the bottom standing screw of described vertical rod, step plate.
Described step plate is welded to form by reinforcing bar and angle steel.
Described step plate lower end is provided with the through hole fixing with terraced beam, and through hole is connected with micro screw on being fixed in terraced beam.
Described terraced beam is selected steel pipe, steel plate, channel-section steel or angle steel.
The bottom of described terraced beam, top or interlude perforation are for the Screw arbor with nut at both-ends of socket joint fixed ladder beam or spreading ladder beam.
Be welded and fixed the Screw arbor with nut at both-ends of step plate on the described terraced beam.
The utility model with respect to the beneficial effect of prior art is:
The utility model project organization is reasonable, and time-consuming taking a lot of work in the time of can effectively solving conventional cat ladder and set up and dismantle affects the problem of follow-up construction follow-up, also can take full advantage of the remaining material of building simultaneously.The terraced beam of the utility model design can be by being used for fixing or the terraced beam of spreading in terraced beam perforation, and mounting or dismounting are convenient; The fixedly angle steel of the utility model design utilizes angle steel to weld the steel disc of different angles, is used for adapting to the variation of scaffold size, adjusts the angle of step plate; The step plate of the utility model design utilizes the welding of reinforcing bar clout and angle steel, takes full advantage of the remaining material of building.

The specific embodiment
Shown in Fig. 1-5, a kind of tool-type combination steel ladder comprises guard rail and vertical rod 1 and half space 2, it is characterized in that: also comprise terraced beam 3, step plate 4 and fixing angle steel 5; Described fixedly angle steel 5 is arc, the fixing multilayer steel disc 6 of different angles on it, and the terraced beams of described fixedly angle steel 5 and four 3 are fixing; Step plate 4 lower ends with fix in terraced beam, step plate 4 upper ends stick in the steel disc 6 of fixing angle steel 5,1 pair of vertical rod is worn step plate 4 and is fixed with nut.Be welded with the steel disc of different angles on the angle steel, effect is fixing step plate, and simultaneously when the variation of support body height, step plate can change fixedly steel disc and adapt to angle and change.
The bottom standing screw 7 of described vertical rod 1, perforation is used for this screw rod 7 fixing in the middle of the step plate 4.
Described step plate 4 is welded to form by reinforcing bar and angle steel.
Described step plate 4 lower ends are provided with the through hole fixing with terraced beam 3, and through hole is connected with micro screw 8 on being fixed in terraced beam.
Described terraced beam 3 is selected steel pipe, steel plate, channel-section steel or angle steel.
The bottom of described terraced beam 3, top or interlude perforation are for the Screw arbor with nut at both-ends of socket joint fixed ladder beam 3 or spreading ladder beam 3.
Be welded and fixed the Screw arbor with nut at both-ends of step plate 4 on the described terraced beam 3.
