Building scaffolding stairs easy to detach and install and erection method thereof

Abstract

The invention discloses building scaffolding stairs easy to detach and install. The stairs comprise a first cross beam, a second cross beam and two side beams, the first cross beam and the second cross beam are fixed at different stair platforms respectively, one end of each side beam is connected with the first cross beam, and the other end of each side beam is connected with the second cross beam; horizontal pedals are arranged between the side beams at equal intervals in the height direction, and the two ends of each pedal are installed on the side beams at the two sides through connecting pieces respectively; each connecting piece comprises a hinge pin and a pulling ring, each hinge pin is a polygonal column, one end of each hinge pin is inserted into an installing hole formed in the corresponding side beam and a locating hole formed in the side face of the corresponding pedal, and each installing hole and each locating hole are matched with the corresponding hinge pin. The invention further discloses an erection method of the building scaffolding stairs easy to detach and install. According to the stairs, the components of the stairs are movably connected, the detachment and installation are convenient and fast, the construction efficiency is improved greatly, the accessories can be utilized repeatedly, the materials are saved, and the construction cost is saved greatly.

Description

technical field [0001] The invention relates to the construction field of building scaffolding stairs, in particular to an easily disassembled building scaffolding staircase and a method for erecting the same. Background technique [0002] During scaffolding construction on a building construction site, it is usually necessary to erect scaffolding stairs. At present, there are various methods for erecting scaffolding stairs. The most common methods include: Method 1. Install two layers of oblique steel pipes on the two stair platforms. Each layer of oblique steel pipes is connected with horizontal steel pipes. Steel pipes form a stepping layer, and then lay plates on the stepping layer, reinforce them with beading or directly bind iron wires. This method of erection is slow and the work efficiency is low. Moreover, if iron wires are used for binding, the iron wires cannot be reused after removal, resulting in waste of materials; Method 2: Rent scaffolding stair components. ...

Steel pipes form a stepping layer, and then lay plates on the stepping layer, reinforce them with beading or directly bind iron wires. This method of erection is slow and the work efficiency is low. Moreover, if iron wires are used for binding, the iron wires cannot be reused after removal, resulting in waste of materials; Method 2: Rent scaffolding stair components. The steps are welded to the side beams of the stairs. There are hook grooves at both ends of the side beams that can quickly overlap the steel pipes at the two platforms of the stairs. The stair components of this method are suitable for standard-story buildings. If the height is different, the steps will not be completely level, and even cause discomfort when stepping on it; Method 3: Lay wooden springboards directly on the horizontal steel pipes of the two platforms of the stairs, and then nail wooden strips on the platforms. This kind of stairs tend to accumulate on the inclined platforms. Stucco is slippery when exposed to water, which poses a great safety hazard
