2) do detachable connection location through the corner platform that is fixed on the steel framework between adjacent tool formula cat ladder monomer, accurate positioning, convenient, reliable;
3) the protective screening foreign matter injury human body that can prevent to fall has improved the safeguard protection performance of tool-type cat ladder;
4) the helper door can play the further restriction idler effect in the construction cat ladder of coming in and going out.
Description of drawings
Fig. 1 is applied to the perspective view in the construction for the utility model tool-type cat ladder;
Fig. 2 is the utility model tool-type cat ladder side structure sketch map;
Fig. 3 is the syndeton sketch map of the utility model steel framework.
The specific embodiment
For the benefit of to the understanding of the utility model structure, be that example is specifically explained below in conjunction with the preferred embodiment of accompanying drawing 1-3 the utility model.
As shown in Figure 1; The utility model construction is cubic with tool-type cat ladder 10; It comprises a steel framework 11; Be connected in tool-type cat ladder monomer 12 and corner platform 13 in the said steel framework 11, said tool-type cat ladder monomer 12 and corner platform 13 are separated out six elementary layers from bottom to top successively with said steel framework 11, are connected with a corner platform 13 on said each elementary layer; And connect through said tool-type cat ladder monomer 12 between the corner platform 13 of adjacent cells layer, so 12 of said tool-type cat ladder monomers are done detachable connection location and are the spiral rising through corner platform 13.
In conjunction with Fig. 1, shown in Figure 3; Two-layer steel framework 11 better connects in order to make up and down; Adjacent steel pipe 21 in the said steel framework 11 interconnects through a splicing sleeve 211; Said splicing sleeve 211 lower ends adopt welding manners to be connected fixing (because lower floor's steel pipe 21 exposes short about 3cm, noting welding quality during welding) with said lower floor steel pipe 21, and said upper strata steel pipe 21 and said splicing sleeve 211 upper ends are provided with the (not shown) of boring a hole at opposite position; Utilize a Φ 8cm screw rod 212 to be arranged in this perforation; Thereby and step up fastening upper strata, said screw rod 212 two ends steel pipe 21 and splicing sleeve 211 upper ends through two nuts 213, the adjacent steel pipe 21 of each steel framework 11 cross side also is to adopt aforesaid way to be fastenedly connected each other equally, guarantees thereby make the resistance to overturning of said steel framework 11 have significantly.On the said steel framework 11 of each elementary layer, also be provided with a plurality of cross one another reinforcing diagonal braces 15, be used for the fastening steel framework 11 of side direction, further increase the safety and firmness performance of tool-type cat ladder 10.
In conjunction with Fig. 1, shown in Figure 2, said tool-type cat ladder monomer 12 is made up of the support body 14 that is set up in 13 on said corner platform and some step plates 141 of being connected in 14 of said support bodys.Said step plate 141 can adopt common plank or bamboo splint, and its thickness is greater than 5cm, and width is greater than 30cm, and the outstanding high jump degree of step plate 141 both sides is not less than 30cm, and is fixed by bolts on the support component 14.Said support body 14 is assembled by complex root reinforced bar support beam; The two ends of support body 14 are set up in respectively on the adjacent corner platform 13; Thereby tool-type cat ladder monomer 12 is connected with said adjacent corner platform 13, also is fixed with the handrail 142 of the safeguard protection that is used for pedestrian's stair activity in said support body 14 1 sides.
In order to limit in the said tool-type cat ladder 10 of freely coming in and going out of construction period idler, the utility model also is equipped with helper door 20 in elementary layer one side of said steel framework 11 bottoms.Around the said steel framework 11 steel wire protective screening (in order to make view succinct, the steel wire protective screening is not shown among Fig. 1) is arranged, the foreign matter that prevents to fall injures human body, has improved the safeguard protection performance of tool-type cat ladder 10.
The utility model forms lower channel use in the People's Bank of China when mainly supplying bridge bent cap (pier cap) or the construction of bridge top, be applicable to height lower channel in the People's Bank of China at positions such as the bridge pier bent cap within 3m～20m scope, cast-in-place superstructure.The utility model can be built the elementary layer of more steel frameworks 11 according to actual needs, and adopts field machining.
For further increasing understanding, below explain to its preparation method to the utility model tool-type cat ladder 10 structures.
1) with the ground (not shown) grinding compacting of tool-type cat ladder 10, and build the thick C25 concrete of 10cm, make its height suitable with the foundation ditch height of ground, every side is slightly than tool-type cat ladder 10 wide 50cm;
2) blanking steel pipe 21 in said ground; Said steel pipe 21 adopts said splicing sleeve to interconnect formation one steel framework 11 in a manner described; Every 3m highly is that an elementary layer marks off six elementary layers with steel framework 11; (should note steel framework 11 accuracies of gauge and steel pipe 21 mutual verticality this moment, accurately reaches the stability of whole assembling tool formula cat ladder 10 with the connection that guarantees upper and lower elementary layer);
3) connect a corner platform 13 at the adjacent cells interlayer, tool-type cat ladder monomer 12 is in 13 location of adjacent corners platform simultaneously;
4) set up a cross one another reinforcing diagonal brace 15 in steel framework 11 side locations of each elementary layer;
5) treat that 15 welding of said reinforcing diagonal brace are accomplished after, welded wire fabric is made the usefulness of protection around steel framework 11.
When dismounting, only need get final product according to the reverse order dismounting; So the utility model is taken into account easy accessibility; The location is reliable, the advantage that the safeguard protection performance is good, and along with the propelling of engineering can change height easily: promptly after the elementary layer of first steel framework 11 is built completion; Hang said tool-type cat ladder monomer 12 and corner platform 13 and connect the location from bottom to top successively through the crane liter, so the novel height that can better adapt to building of this use.
