Abstract
The invention discloses a portable steel structure ladder which comprises a steel section with U-shaped or H-shaped cross section, wherein the steel section comprises two side wings, the side wings are provided with insertion holes facing each other, a cross bar is inserted in the insertion holes, and positioning steps and handles are arranged on one side of the cross bar. Preferably, an accommodating groove is formed in the cross bar, positioning steel balls are arranged inside the accommodating groove and engaged with the insertion holes, and springs are arranged at the lower part of the positioning steel balls. The portable steel structure ladder has the advantages of providing convenience for operators to climb to a high place and being safer.
Description
Technical field
The present invention relates to the steel work technical field, especially relate to a kind of portable steel ladder.
Background technology
The characteristics such as the installation that steel building has is convenient are used widely it.But steel building need to regularly carry out preservative treatment, thereby needs personnel's operation of climbing.For this reason, the operator is many carries out work by stay cord with self being hung in the eminence mode.Obviously, such mode is comparatively dangerous.
Summary of the invention
The purpose of this invention is to provide a kind of portable steel ladder, the person climbs operation and safer characteristics that it has the convenient operation.
The technical solution adopted in the present invention is: portable steel ladder comprise that cross section is the shaped steel of " U " shape or " H " shape, and this shaped steel comprises 2 flanks, described flank is provided with the jack of mutual correspondence, be inserted with cross bar in this jack, simultaneously, a side of this cross bar is provided with positioning step and handle.
Described cross bar is provided with holding tank, is provided with the positioning ball that matches with jack in this holding tank, and this positioning ball bottom is provided with spring.
The present invention is compared with existing technology the advantage that has: the convenient operation person operation of climbing, and safer.Portable steel ladder of the present invention is inserted in some cross bars in the jack in use, even shaped steel forms cat ladder, convenient operation the person climb.Owing to avoid using stay cord that self is sling, thereby safer.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is the front view (broken section) of embodiments of the invention;
Fig. 2 is the A section enlarged drawing (analysing and observe) of Fig. 1.
Among the figure: 10, shaped steel, 11, flank, 111, jack; 20, cross bar, 21, positioning step, 22, handle, 23, positioning ball, 24, holding tank, 25, spring.
The specific embodiment
Embodiment, see illustrated in figures 1 and 2: portable steel ladder comprise that cross section is the shaped steel 10 of " U " shape or " H " shape, and this shaped steel 10 comprises 2 flanks 11.Among the present invention, this flank 11 is provided with the jack 111 of mutual correspondence.That is, the jack 111 on these 2 flanks 11 arranges in pairs.Simultaneously, be inserted with cross bar 20 in this jack 111, and a side of this cross bar 20 is provided with positioning step 21 and handle 22.Like this, cross bar 20 inserts in the jacks 111, can make shaped steel 10 form cat ladders, and when not using cat ladder, cross bar 20 is extracted get final product.Wherein, this positioning step 21 is used for making cross bar 20 be unlikely to pass from the other end of jack 111, and shakes hands 22 to be convenient to the user and to insert or extract cross bar 20.
Optimize, this cross bar 20 is provided with holding tank 24, is provided with the positioning ball 23 that matches with jack 111 in this holding tank 24, and these positioning ball 23 bottoms are provided with spring 25.Certainly, to refer to its top be spherical getting final product for so-called positioning ball 23.That is, after this cross bar 20 inserted and puts in place, positioning ball 23 ejected, and made the cross bar 20 can self falling, thereby this cat ladder is safer.
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes manual of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
