Abstract
The invention discloses a scaffolding ladder comprising a plurality of steps and two symmetric supports. The steps are connected between the two supports. A hook is disposed at the bottom of the upper end of each support. A hook part of each hook extends out of the corresponding support. A locking bar is arranged at an opening of each hook to close the opening of the hook. When the ladder composed of the steps, the supports and the hooks needs to be used, the whole ladder is moved to a specific position and is hooked to steel tubes of a scaffold for fixing the position through the hooks so as to prevent hook dropping. When the ladder is used, the openings of the hooks are closed by the locking bars; after using, the hooks are removed and the ladder is removed for next use; during use, the ladder is handy and simple and reusable; and the problem that the existing erected pedestrian path is troublesome to construct, material-consuming and labor-consuming is solved.
Description
Technical field
The present invention relates to cat ladder, particularly a kind of setting up at scaffold is convenient to the staff at the current cat ladder of operation layer up and down.
Background technology
In the existing building engineering, when the structure stair do not come into operation as yet, need set up the walkway between operation layer up and down, it adopts steel pipe and the lumps of wood to be erected at the outside of scaffold, and this walkway and frame hand frame are connected as a single entity, when the work items completion, the structure stair just build up and it need be removed, not only construct loaded down with trivial details, consumable material, consumption is artificial, and can not reuse, and influences programming.
Summary of the invention
The problem to be solved in the present invention provides a kind of scaffold cat ladder, can make the integrated cat ladder of typing, when the structure stair do not come into operation as yet, directly whole cat ladder is hung on the steel pipe of scaffold, also conveniently takes off and is moved to other places.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of scaffold cat ladder, comprise that several mark time and the support of two symmetries, described marking time is connected between two supports, described support upper end below is provided with hook, and the hook portion of hook is extended the described hook opening part of support and is provided with anti-drop rod and can seals the hook opening.By mark time, support and hook form cat ladder, when needing to use, whole cat ladder moved to formulates the position, the steel pipe that hooks scaffold with hook comes off for preventing hook, during use with settling position, seal the hook opening by mousing-hook, make make good use of after, take off hook, whole cat ladder is taken away to give over to uses next time, in use, convenient and simple, and can reuse saving of work and time.
As preferably, described hook is provided with a fastener, and described anti-drop rod one end is buckled on the described fastener, and the other end is hinged on the hook.When being hung up or take down, the scaffold cat ladder end of anti-drop rod need be threaded off from fastener.Anti-drop rod has guaranteed that the work safety of constructor when operation prevents that hook from causing the danger of breaking off relations under unfavorable conditions such as strong wind.
As preferably, described support is the framework of a parallelogram, and the material of its four edges is angle steel or square steel, and the adjacent frame side weld connects.Adopt the shape of parallelogram, make that when cat ladder tilted, the base kept level, be beneficial to stablizing when placing, also be convenient between support, arrange and mark time.
As preferably, the described 7-15 of having marked time and be distributed between the support.
As preferably, described marking time comprises that the junction plate of both sides, junction plate laterally are connected on the described support, connects at least two connecting rods between the junction plate.Junction plate and connecting rod have constituted marks time, simple in structure, is convenient to be connected with support.
As preferably, described connecting rod has three, and its material is angle steel or square steel.
As preferably, described hook is formed by the reinforcing bar bending, and the end of hook is welded on described support below.
After adopting technique scheme, the present invention has following advantage: by mark time, support and hook form cat ladder, when needing to use, whole cat ladder moved to formulates the position, hook the steel pipe of scaffold with settling position with hook, if make make good use of after, take off hook, whole cat ladder is taken away to give over to uses next time, in use, convenient and simple, and can reuse saving of work and time; The used material of cat ladder has angle steel, square steel and reinforcing bar, all can adopt the remaining leftover pieces in building site, is easy to make in the building site, connects and adopts welding manner, and is solid and reliable.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the partial enlarged drawing of Fig. 1;
The structural representation of Fig. 3 for marking time among the present invention.
The specific embodiment
As Figure 1-3, a kind of scaffold cat ladder comprises the support 2 of 1 and two symmetry of marking time, and described marking time 1 is connected between two supports 2, and described marking time 1 has 7-15 and be distributed between the support 2, and be preferred in the present embodiment 8.Below, described support 2 upper ends is provided with hook 3, and the hook portion of hook 3 is extended support 2, and the hook portion of described hook 3 is formed by the reinforcing bar bending, and the end of hook 3 is welded on described support 2 belows.Described hook is provided with a fastener 32, and described anti-drop rod 31 1 ends are buckled on the described fastener 32, and the other end is hinged on the hook 3.When being hung up or take down, the scaffold cat ladder end of anti-drop rod need be threaded off from fastener 32.Anti-drop rod 31 has guaranteed that the work safety of constructor when operation prevents that hook from causing the danger of breaking off relations under unfavorable conditions such as strong wind.Described hook 3 adopts the reinforcing bar bending to form, and is easy to make on-site.By mark time 1, support 2 and link up with 3 and form cat ladder, when needing to use, move whole cat ladder to the formulation position, with the hook 3 steel pipes that hook scaffold with settling position, if make make good use of after, take off hook, whole cat ladder taken away to give over to use next time, in use, convenient and simple, and can reuse.
Described support 2 is the framework of a parallelogram, adopt the shape of parallelogram, make when cat ladder tilts, its base keeps level, be beneficial to stablizing when placing, also be convenient between support 2, arrange and mark time, the material of four edges of support 2 is angle steel or square steel, the adjacent frame side weld connects, described 1 junction plate 11 that comprises both sides of marking time, and junction plate 11 laterally is connected on the described support 2, connect at least two connecting rods 12 between the junction plate 11, in the present embodiment, described connecting rod 12 is preferably three, and its material is angle steel or square steel.The used material of cat ladder has angle steel, square steel and reinforcing bar, all can adopt the remaining leftover pieces in building site, is easy to make in the building site, connects and adopts welding manner, and is solid and reliable.
