Description
Technical Field
The invention relates to the technical field of building steel structures, in particular to a steel structure building stair with a switchable charging surface.
Background
In the prior art, a stair with the application number of '201720925181.8' and an inclined plane type capable of being mutually converted consists of a frame, an eccentric shaft, a conversion table surface belt and the like; the frame is formed by oppositely fixedly welding a pair of angle irons through a front steel plate and a rear steel plate; the front vertical surface of the angle iron is provided with a pair of through holes and a plurality of pairs of pin grooves, and the tail part of the angle iron is provided with a transverse long hole; a conversion table belt formed by connecting a panel, a vertical plate and a tail end vertical plate in series is arranged in the frame, and in order to prevent the conversion table belt from generating a thrust dead point, the conversion table belt is adjusted by an eccentric shaft below the conversion table belt. When the inclined-plane type stairs are needed, the tail part of the tail end vertical plate can be moved out from the strip hole, and the tail end vertical plate is pulled down to be placed in a horizontal state; when the stair is needed, the tail end vertical plate is pushed upwards, and the tail part of the tail end vertical plate is inserted into the strip hole.
However, the stair with steps and inclined planes capable of being switched with each other still has the following obvious defects in the using process: 1. the top end panel, the vertical plate, the panel and the tail end vertical plate are rotatably connected in series through the pin shaft to form a conversion table belt, and the conversion table belt is arranged in the frame through the association of the top end connecting pin and the through hole, so that the whole structure needs to be operated when the whole structure is switched into a step type or an inclined plane type due to the conversion table belt formed by the series connection, instead of switching each part respectively, the operation is very troublesome, and once any part is broken or damaged, the whole conversion table belt cannot be used due to the series connection; 2. if the inclined floor slab is needed, people can move the tail part of the tail end vertical plate out of the strip hole of the frame and pull the tail end vertical plate downwards to be placed in a horizontal state; if need the stair of step, people will push up the tail end riser, inject the afterbody of tail end riser in the rectangular downthehole of frame after finishing, so, when switching, need control the tail end riser of end, tail end riser top still establishes ties there is other structure for need consume bigger power during the switching, very troublesome.
