Abstract
The invention discloses a steel ladder compartment for a pedestrian courtyard and a construction method, and relates to the technical field of a mine safety appliance. The steel ladder compartment comprises a ladder platform and a steel ladder, wherein the ladder platform is arranged on the wall of the courtyard; the steel ladder is arranged on the ladder platform; the ladder platform is composed of an anchor rod, a base plate, a cross beam and a steel rail; one end of the anchor rod is inserted into the wall; the base plate is welded at the other end of the anchor rod; the cross beam is welded on the base plate; the steel rail is paved and fixedly disposed on the cross beam; a ladder opening for placing the steel ladder is also reserved in the steel rail. The steel ladder compartment has the beneficial effects that reduction of destructive power of an impact wave is facilitated by the overall structure strength of the steel ladder compartment in a form of a grating structure, the steel ladder compartment is less in repair maintenance, and the material is corrosion resistant, good in safety, long in service life, and high in cost performance. In addition, a lot of eliminated rail scraps in the mine production process or tubular products of which the strength meets the requirements are adopted as main materials, so that the cost is greatly reduced.
Description
【Technical field】 [0001] The invention relates to a mine safety facility, which is a steel structure ladder room erected in a patio for pedestrians. 【Background technique】 [0002] In order to meet the needs of mine safety production operations, ladders are installed in the patio between adjacent production stages for operators to pass up and down, which is one of the most common forms of safety facilities. In the traditional ladder room, except some ladders are made of steel, the stepping platform is made of wood structure. This kind of ladder room is widely used by mining enterprises because of the light material selected and easy erection. With the progress and development of the times, this kind of wooden ladder room has exposed many shortcomings: the wood and its structural strength are low, and the patio ladder room serving the mining field is easily damaged by blasting operations, which increases the repair frequency and cost. The hidden dangers of operation safety a...
