Embodiment 1

[0046] Embodiment 1: A prefabricated component of a staircase, which is mainly used to facilitate the entire hoisting of the staircase. It separates the entire prefabricated component, including the load-bearing part 1 and the footboard 2 fixed on the load-bearing part 1. When hoisting, the load-bearing part 1 is hoisted first, and then the footboard 2 is installed. It is carried out separately to reduce the weight of the stairs, so that it can be installed with smaller and more flexible hoisting tools during hoisting, making hoisting more convenient. In addition, in many cases, the same building has the same height, but the stair positions are different, resulting in different widths of the designed stairs. At this time, the entire stair mold needs to be re-made, and this structure can allow the load-bearing part 1 to be directly produced. , and the pedal 2 can be produced separately, thereby reducing the difficulty of production.

[0047] At least two load-bearing parts 1 a...

Embodiment 2

[0053] Embodiment 2: A kind of stair prefabricated component, its general structure is identical with embodiment 1, and its difference is that the structure between pedal 2 and support platform 13 is different to some extent, in embodiment 2, in pedal 2 Connecting posts 23 are added at both ends, and the connecting posts 23 are arranged in pairs on both sides of the fixing hole 21 respectively. Simultaneously, the connecting hole 14 is set on the supporting platform 13, the diameter of the connecting hole 14 is greater than the diameter of the connecting column 23, and the gap between the connecting column 23 and the connecting hole 14 is the same as that of the mounting sleeve 31 and the fixing hole 21 when they are coaxial. Fit, that is, equal.

Embodiment 3

[0054] Embodiment 3: A prefabricated component of a staircase, its general structure is the same as that of Embodiment 1, the difference lies in the structure of the footrest 2 and the riser 4, in Embodiment 3, the footrest 2 and the riser 4 are in pairs The pouring is one-time forming, therefore, the riser 4 and the foot board 2 form an L-shaped structure, and on the side of the foot board 2 away from the riser 4, a fixed column 22 is set on the side away from the riser 4, and the riser 4 is far away from the riser 4. A mounting hole 41 is provided on one side of the pedal 2, and the structure of the positioning column is the same as that of the positioning column in Embodiment 1.

Abstract

The invention relates to the technical field of prefabricated parts and discloses a stair prefabricated part and a construction method thereof. The stair prefabricated par comprises bearing parts andtreads fixed on the bearing parts, wherein the number of the bearing parts is at least two, a plurality of steps are arranged on the bearing parts, the treads are fixed on the steps, each bearing partcomprises a supporting beam, a lap joint part and a supporting table, the lap joint parts, the supporting tables and the supporting beams are integrally arranged, the lap joint parts are arranged atthe two ends of the supporting beams, the supporting tables are arranged on the supporting beams to form the steps, and the treads are fixed on the supporting tables. The bearing parts and the treadsare separated, compared with the prior art, the treads can be effectively installed in a separated mode, so that the treads can be hoisted respectively in the hoisting process, hoisting equipment canadopt small equipment, the installation convenience is greatly improved, and in the installation process, due to the fact that the structure of the prefabricated part is split, fine adjustment can beconveniently carried out after installation of the component.

Description

technical field [0001] The invention relates to the technical field of prefabricated components, more specifically, it relates to a stair prefabricated component and a construction method thereof. Background technique [0002] Stairs are the construction of traffic between floors in a building. The Chinese patent with the notification number CN206655409U discloses a prefabricated reinforced concrete slab staircase component, which consists of an upper tread plate, a prefabricated stair main body, stair treads, a lower tread plate, It is composed of water retaining edge, drip line and prefabricated stair anti-slip strip. When in use, the whole is directly hoisted to the designated position for placement, then finely adjusted, and finally fixed to complete the installation of the entire staircase. [0003] In the actual practical process, because the stairs are generally composed of solid prefabricated components, their weight is relatively large, and a large crane is required...
