Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.A kind of vertical fragmentation Assembled rotary cat ladder, is formed as shown in figures 1 to 6, and comprise cat ladder support unit 1 and foot-operated step unit 2, foot-operated step unit 2 is positioned at cat ladder support unit 1; Cat ladder support unit 1 comprises head tree 3, head tree 3 is connected with structural framing 4, and head tree 3 top is provided with alignment pin 5; Foot-operated step unit 2 comprises and somely turns to platform 6, and adjacent two pieces turn to be connected with between two pieces of cat ladder margin plates, 7, two pieces of cat ladder margin plates 7 between platform 6 and are connected with some ladder rungs 8; The described top of the edge of platform 6 and cat ladder margin plate 7 that turns to is provided with hand rail 9.
Described cat ladder support unit 1 can by the head tree 3 of alignment pin 5 socket connection last layer cat ladder support unit 1; Described structural framing 4 connection turns to platform 6, turns to platform 6 edge to be provided with baseboard 10.
Described main pillar 3 adopts the thick walled steel tube of more than Ф 100mm, the structural framing 4 channel-section steel welding that thickness is not less than 100mm combines, platform 6 is turned to be not less than the checkered steel plate of 4mm for thickness, the baseboard 10 being highly not less than 200mm is installed, mainly in order to prevent the wisp of underfooting from falling from high altitude turning to the bottom of the edge of platform 6 and hand rail 9.
During installation, as long as be erected on the structural framing 4 of cat ladder support unit 1 by the foot-operated step unit 2 made, one deck vertical fragmentation Assembled rotary cat ladder can be completed; When needs arrange multilayer vertical fragmentation Assembled rotary cat ladder, the bottom of one deck vertical fragmentation Assembled rotary cat ladder head tree 3 is plugged on the alignment pin 5 at another layer of vertical fragmentation Assembled rotary cat ladder head tree 3 top.
Due to field ground out-of-flatness, very large difficulty is caused to installation first floor steel inclined ladder, in order to better levelling fixing, the steel plate of 400mm × 400mm × 20mm is utilized to make basis, at the diagonal center of steel plate, utilize Φ 108 × 4mm, the high steel pipe manufacturing alignment pin for 500mm, bottom utilizes the i iron of 150mm to support.According to the real size of the pillar of steel inclined ladder, utilize the reinforcing bar of φ 28 to accomplish fluently earth anchor on the ground at the scene, the degree of depth is about 1000mm, supports in order to be welded and fixed foundation slab.The adjustment process of foundation slab needs survey crew cooperation to execute.
Four main pillars 3 adopt the steel pipe of Φ 114 × 4mm, synthesize the structural framing 4 of 3460mm × 2600mm × 2400mm by the channel-section steel soldering group that 100mm is thick.The length being arranged on the main column upper section of cat ladder is that the alignment pin 5 of 600mm adopts Φ 108 × 4mm steel pipe manufacturing; When upper and lower layer cat ladder combination, can by alignment pin 5 be enclosed within inside the main pillar 3 in upper strata, exposed length is 300mm.Single-unit cat ladder turns to platform 6, adopts channel-section steel and head tree 3 to be welded into frame construction, is of a size of 800mm × 2400mm, lays the checkered steel plate that 4mm is thick above; Bottom is provided with the baseboard 10 being not less than 200mm, adopts the steel plate that 4mm is thick to make.Cat ladder margin plate 7 adopts 260mm × 4000mm × 10mm steel plate to make, and the degree of climbing that inclines is 35 °.Ladder rung 8 adopts the checkered steel plate of 260mm × 1100mm to make.Hand rail 9 adopts Φ 20mm carbon steel tube to make, and is highly not less than 1200mm, is installed on and turns to platform 6 and cat ladder margin plate 7 edge.On hand rail 9 crosspiece adopt Ф 20mm carbon steel tube.
