The specific embodiment
Come the boat segmental that is used for of the present utility model is shelved the simple and easy cat ladder of construction and done further and elaborate below in conjunction with accompanying drawing and specific embodiment, but can not limit protection domain of the present utility model with this.
The purpose of this utility model be to provide a kind of when segmentation is shelved state and is built constructor's instrument of segmentation up and down, with solve segmentation in the past shelve adopt in the building course install that the fastness that the steel ladder produces is poor temporarily, the problem of installing/dismounting process complexity, repetition and waste manpower and materials.
Of the present utility model be used for boat segmental shelve construction simple and easy cat ladder overall structure as shown in Figure 1, to be that the utility model is a kind of be used for the structural representation that boat segmental is shelved the simple and easy cat ladder of construction to Fig. 1.As seen from the figure, the utility model is used for boat segmental and shelves the simple and easy cat ladder primary structure of construction and comprise support, platform and the ladder that is obliquely installed.
Described support 1 is built by perpendicular pillar 11 and lateral strut 12, connects the besieged city rectangular box in the bottom of support by four lateral struts, 12 head and the tail.
Four perpendicular pillars 11 are square the ground vertical fixing in an end of square frame, are fixed with a square platform 3 at four tops than long perpendicular pillar 11.The other end of side of this platform 3 and bottom square frame be fixed be obliquely installed ladder.As shown in Figure 2, to be that the utility model is a kind of be used for the elevation that boat segmental is shelved the simple and easy cat ladder of construction to Fig. 2.
Be fixed with many short perpendicular pillars 11 at frame bottom square frame and ladder middle part, be provided with lateral strut 12 at the middle part of adjacent perpendicular pillar 11, the crossover location of described perpendicular pillar 11 and lateral strut 12 fixes.And the annexation between perpendicular pillar 11 and lateral strut 12 and the ladder as shown in Figure 4, and Fig. 4 is that a kind of boat segmental that is used for of the utility model is shelved in the simple and easy cat ladder of construction link position enlarged drawing between ladder and support.
Above-mentioned ladder by ladder 6, mark time 2 and handrail 5 form.Marking time 2 is parallel to horizontal plane, and 2 the two ends of marking time are fixed into ladder 6 by four steel pipes, and vertical fixing has handrail 5 on the ladder 6 of every side.The specific requirement of ladder is:
The spacing of marking time on the ladder is 250mm;
Handrail height is 1020mm;
45 °～55 ° of the angles of inclined ladder.
For this simple and easy cat ladder can be free on ground grading the shift position, be convenient between different shelves, move and use, be provided with four rolling 7 at four jiaos of places of square frame of described frame bottom.
In order to protect the safety of constructor when the ladder up and down, described platform 3 is provided with guardrail 8.Guardrail 8 mainly is positioned at the corner location of platform 3, and wherein the guardrail of two close inclined ladders and the handrail of ladder link together.As shown in Figure 3, to be that the utility model is a kind of be used for the lateral view that boat segmental is shelved the simple and easy cat ladder of construction to Fig. 3.
Simple and easy cat ladder in use will be aspired for stability, safety, does not allow substantially to occur rocking unstable situation, for this reason, is provided with channel-section steel 4 between the parallel lateral strut 12 in mid-stent.Channel-section steel 4 plays the effect of straining the lateral strut 12 that is parallel to each other, and makes it can not occur rocking.
The joint intersection must cut and guarantee fit-up gap≤5mm between the pipe, fillet weld height 6mm, and the joint through welding is according to the removable simple and easy cat ladder of different height of lift making differing heights.
Of the present utility model be used for boat segmental shelve construction simple and easy cat ladder user mode as shown in Figure 5, to be that the utility model is a kind of be used for the user mode figure that boat segmental is shelved the simple and easy cat ladder of construction to Fig. 5.As seen from the figure, at first to produce simple and easy cat ladder, make that the height of segmentation is identical on height and the shelf of simple and easy cat ladder upper mounting plate according to the height of segmentation on the shelf, like this can so that the constructor use up and down.Requiring the spacing of marking time on the ladder is 250mm; Handrail height is 1020mm; 45 °～55 ° of the angles of inclined ladder.And the joint intersection must cut assurance fit-up gap≤5mm, fillet weld height 6mm, joint through welding between the assurance pipe.Above-mentioned purpose is to increase fastness and stability.
Crane segmentation is hung be pulled on the shelf after, cat ladder is pushed into shelf position, require ground smooth, roller rolls, and then can reduce the constructor pushes away required strength smoothly.The close shelf of cat ladder is also adjusted after the position, utilizes solid piece that roller is fixed, and makes cat ladder not removable.Then the constructor can realize the constructing operation in the segmentation by cat ladder segmentation up and down.After finishing, construction just simple and easy cat ladder can be pushed away shelf, shift position to next shelf place.
Undoubtedly, the foregoing description only is the application in practice of simple and easy cat ladder that boat segmental is shelved construction that is used for of the present utility model, and the boat segmental that is used for of the present utility model is shelved the simple and easy cat ladder of construction and can also be had other structural changes and parameter to set.Generally speaking, the boat segmental that is used for of the present utility model is shelved the variation that the protection domain of the simple and easy cat ladder of construction comprises that also other it will be apparent to those skilled in the art that and is substituted.
