Embodiment 1

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

Embodiment 2

[0053] Embodiment 2: A stair prefabricated member, the general structure of which is the same as that of Embodiment 1, and the difference lies in the structure between the footboard 2 and the support table 13. In Embodiment 2, the footboard 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. At the same time, a connecting hole 14 is provided on the support table 13, the diameter of the connecting hole 14 is larger than that of the connecting column 23, and the gap when the connecting column 23 and the connecting hole 14 are coaxial is the same as the gap when the mounting sleeve 31 and the fixing hole 21 are coaxial fit, i.e. equal.

Embodiment 3

[0054] Embodiment 3: A stair prefabricated component, the general structure of which is the same as that of Embodiment 1, and the difference lies in the structure of the footboard 2 and the vertical plate 4. In the embodiment 3, the footboard 2 and the vertical plate 4 are paired It is formed by pouring once. Therefore, the vertical plate 4 and the footboard 2 form an L-shaped structure, and a fixed column 22 is provided on the side of the footboard 2 away from the vertical plate 4 on the side away from the vertical plate 4. The vertical plate 4 is far away from the vertical plate 4. A mounting hole 41 is provided on one side of the footboard 2 , and the structure of the positioning column is the same as that of the positioning column in the first embodiment.

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, and more particularly, to a prefabricated stair component and a construction method thereof. Background technique [0002] The staircase is the construction of the traffic between floors in the building. The Chinese patent with the announcement number CN206655409U discloses a prefabricated reinforced concrete slab stair member, which consists of an upper tread, a prefabricated stair body, a stair step, a lower tread, It is composed of water retaining edge, drip line and prefabricated stair anti-skid strip. When in use, directly hoist the whole to the designated position for placement, and then make subtle position adjustments, and finally fix it to complete the installation of the entire stair. [0003] In the actual practical process, since the stairs are generally composed of solid prefabricated components, their weight is relatively large, and a larger crane is required for ho...
