Description
Technical field
The utility model relates to servant's cat ladder on a kind of tool-type that is applied in the job site.
Background technology
People's cat ladder of job site is all built with scaffold usually, not only build, dismantle cumbersome, many steel pipes need be barricaded as stereochemical structure or dismantle this stereochemical structure, more time-consuming, and safety is not fine, can not prevent that dropped object from hurting sb.'s feelings.
Summary of the invention
The technical problems to be solved in the utility model provides servant's cat ladder on the job site tool-type that a kind of safeguard protection performance is good and dismounting is easy.
The technical scheme that the utility model adopted is: servant's cat ladder on the tool-type of a kind of job site comprises: pedestal, overlay one deck or multilayer cat ladder monomer on the described pedestal.The dismountable connection between described pedestal and the described cat ladder monomer of orlop and between the adjacent cat ladder monomer.By being fixed on the angle steel location on the pedestal, two inner surfaces of described angle steel all fit with the surface of orlop cat ladder monomer between described pedestal and the orlop cat ladder monomer; By being fixed on the described angle steel location of lower floor, two inner surfaces of described angle steel all fit with the surface of the cat ladder monomer on upper strata between the adjacent described cat ladder monomer.Described cat ladder monomer has the step that runs through its height, and two steps on the adjacent cat ladder monomer are connected by the platform on the cat ladder monomer and are spiral and rise.The sidepiece of described cat ladder monomer also has protective screening.
Because the employing of technique scheme the utlity model has following advantage: the first, just whole cat ladder assembling or dismounting can be taken and torn open conveniently, save time by installing or dismantle the step monomer; The second, locate accurate positioning, convenience, reliable between pedestal and the orlop cat ladder monomer and between the cat ladder monomer by angle steel; Three, the protective screening foreign matter that can prevent to fall is hurted sb.'s feelings, and can improve the safeguard protection performance of cat ladder.

Fig. 2 is the stereogram of embodiment two;
Wherein: 1, pedestal, 2, the cat ladder monomer, 20, framework, 21, platform, 22, step, 23, handrail, 24, protective screening, 25, the cross reinforcing rib, 26, the column reinforcing rib, 27, stiffener, 28, bolt assembly, 3, angle steel.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:
Embodiment one:
Referring to servant's cat ladder on the tool-type that is applied in the job site shown in Figure 1, comprising: pedestal 1, overlay four layers of cat ladder monomer 2 on the described pedestal 1.
Described pedestal 1, cat ladder monomer 2 are cubic.The height a of the height of described pedestal 1 and foundation ditch is suitable, and half of the height of described cat ladder monomer 2 and floor height b is suitable, and then the combination of two cat ladder monomers 2 is suitable with floor height b.This is a kind of actual mode of occupation, is not the qualification to the cat ladder height, according to the actual requirements, can also build the cat ladder monomer 2 of more multi-layered number.
Between described pedestal 1 and the described cat ladder monomer 2 of orlop and between the adjacent cat ladder monomer 2 by 28 dismountable connections of bolt assembly.
By being fixed on angle steel 3 location on 1 four jiaos of the pedestals, two inner surfaces of described angle steel 3 all fit with the surface of orlop cat ladder monomer 2 between described pedestal 1 and the orlop cat ladder monomer 2; Described angle steel 3 location on 2 four jiaos of the cat ladder monomers by being fixed on lower floor between the described cat ladder monomer 2, two inner surfaces of described angle steel 3 all fit with the surface of the cat ladder monomer 2 on upper strata.Thus, the position of cat ladder monomer 2 has well been located.
Described cat ladder monomer 2 has the step 22 that runs through its height, and described step 22 is positioned at a side of cat ladder monomer 2.Two steps 22 on the adjacent cat ladder monomer 2 are connected by the platform on the cat ladder monomer 2 21 and are the rising shape that spirals.
The sidepiece of described cat ladder monomer 2 has protective screening 24 (in Fig. 1, in order to make view succinct, the protective screening 24 of cat ladder monomer 2 left sides and rear side does not show).
Also be connected with stiffener 27 between described cat ladder monomer 2 and the fixed building, described stiffener 27 is microscler iron bar.
Cat ladder with said structure is taken into account easy accessibility, is located the advantage reliable, that security protection is high; and along with the propelling of engineering can change height easily: the pedestal 1 of promptly after the foundation ditch pouring is finished, can dismantling; build the nethermost two-layer cat ladder monomer 2 (utilizing tower crane to realize easily) of to dismantle after finishing when first floor, can better adapt to the height of building.And common scaffold is dismantled inconvenience because it has stereochemical structure, therefore can not change height along with the propelling of engineering.
Embodiment two:
Referring to pedestal shown in Figure 21 and orlop cat ladder monomer 2, cat ladder monomer 2 is roughly the same with the cat ladder monomer 2 among the embodiment one, and difference is: a side that is positioned on the described step 22 away from step monomer 2 side surfaces also is fixed with the handrail 23 that is used for safeguard protection; The side surface of described cat ladder monomer 2 also be fixed with reinforcing rib with the intensity that improves cat ladder monomer 2, that it can be built into is more high-rise, this reinforcing rib can be cross reinforcing rib 25 or the column reinforcing rib 26 that extends along cat ladder monomer 2 short transverses.
