Description

Technical Field

[0001] The invention relates to the technical field of building construction tools, and in particular to a ladder component for a segmented fixed steel lattice column. Background Art

[0002] With the continuous expansion of the scale of modern construction projects, more and more buildings tend to adopt large-space basement structures, which makes deep foundation pit projects more common and the application of support systems more mature. In areas with poor soil conditions, an internal support system combining steel lattice columns and concrete support beams is often adopted. When using this internal support system, soil will be trapped in the steel lattice columns and need to be manually cleaned. Usually, after the excavation of the earthwork is completed, the height of the steel lattice columns is relatively high. If workers directly climb the lattice columns to clean the soil, there will be a safety risk of soil falling and injuring their hands and feet. It is often necessary to use an operating frame to remove the soil in the high lattice columns. Due to the large number of steel lattice columns in the support system, the repeated erection and dismantling of the operating frame is inefficient and the implementation cost is high.

When in use, the two ends of the cross bar are clamped on the outer side of the lattice column angle steel, and the cross bar and the horizontal part together form a hook part.

[0019] The present invention will be further described below in conjunction with embodiments:

[0020] A ladder component for a segmented fixed steel lattice column comprises a hook part for hanging on the lattice column, the hook part is connected with a pedal 3 for climbers to step on and a gripper for climbers to hold.

[0021] Preferably, it comprises a "J"-shaped special-shaped rod 1, which comprises a raised portion 11 in the middle and horizontal portions 12 on both sides. When in use, the horizontal portion 12 is stuck on the inner side of the lattice column angle steel, and the end of the raised portion 11 away from the lattice column is a gripper.

[0022] The top of the raised portion 11 is fixedly connected to the pedal 3 , and the bottom of the raised portion 11 is fixedly connected to the crossbar 2 . When in use, both ends of the crossbar 2 are clamped on the outside of the lattice column angle steel, and the crossbar 2 and the horizontal portion 12 together form a hook portion.

[0023] Preferably, a plurality of “V”-shaped reinforcing rods 4 are provided at the bottom of the cross bar 2 , and two ends of the reinforcing rods 4 are fixedly connected to the cross bar 2 and the raised portion 11 , respectively.

[0024] Preferably, the reinforcing rod 4 includes a vertical section 41 arranged vertically and an inclined section 42 arranged obliquely, the bottom of the vertical section 41 is fixedly connected to the bottom of the inclined section 42, the top of the vertical section 41 is fixedly connected to the cross bar 2, the top of the inclined section 42 is fixedly connected to the bottom of the raised portion 11 and the connection point is located at one end of the raised portion 11 away from the lattice column.

[0025] Preferably, there are two reinforcing rods 4 , which are symmetrically arranged with respect to the symmetry axis of the raised portion 11 .

[0026] Preferably, the pedal 3 comprises a rectangular frame 31 , the frame 31 is fixedly connected to the raised portion 11 , and a metal grid 32 for support is fixedly disposed in the frame 31 .

[0027] When the present invention is used, the present invention is first tilted so that the two horizontal parts 12 of the special-shaped rod 1 extend into the inner side of the lattice column; the present invention is rotated to keep the raised part 11 of the special-shaped rod 1 in a horizontal state, and the present invention is placed at the bottom of the section of the lattice column. Even if the bottom of the special-shaped rod 1 abuts against the gusset plate at the bottom of the section of the lattice column, the hook part formed by the crossbar 2 and the horizontal part 12 can slide up and down along the angle steel support of the lattice column and be horizontally limited. The gusset plate provides longitudinal support for the special-shaped rod 1, and the vertical section 41 of the reinforcing rod 4 abuts against the side wall of the gusset plate to provide support for the outer side of the raised part 11, which plays a certain strengthening role. The present invention is easy to install. By hanging a number of the present inventions on the lattice column at intervals, a device that can provide an operating surface for both climbing and grasping can be formed, and it can be conveniently disassembled from top to bottom after use, and the repeated assembly and disassembly is efficient and cost-effective.
