Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a decorative construction scaffold for an indoor multi-story cross staircase structure and its construction method. Background Technology

[0002] In the case of indoor staircases (such as...) Figure 1 (As shown) During high-altitude decoration construction, suspended platforms or full-span scaffolding are often used. The indoor stairwell contains four vertically arranged staircases, each connecting to the upper and lower floors of its respective floor. The upper and lower floors of adjacent staircases intersect in the vertical projection plane. The intersection areas of these multi-story staircases are far from the floor slabs, creating many blind spots during suspended platform construction. Furthermore, because the two staircases between the four floors completely overlap vertically, it is impossible to erect scaffolding above them. Using construction machinery is also difficult due to space constraints and the considerable height, making it hard to fully deploy and complete the construction. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a construction scaffolding and construction method for interior multi-story cross staircase structures are provided to solve the problem of the inability to erect full-span scaffolding for interior multi-story cross staircase decoration construction.

[0004] To achieve the above objectives, a decoration construction scaffolding for an indoor multi-story cross staircase structure is provided, comprising:

[0005] The indoor multi-level intersecting staircase includes two rows of staircases in the vertical direction, each row of staircases including multiple overlapping staircases in the same direction in the vertical direction. The staircases in the same direction of the two rows of staircases are arranged alternately, and the staircases in the same direction of the two rows of staircases are intersecting in the vertical projection plane. The decoration construction scaffolding includes:

[0006] Two full-span scaffolding structures are erected on the floor of the stairwell, and the two full-span scaffolding structures are respectively set on opposite sides of a row of stairs;

[0007] Multiple supports, each support comprising a support plate and multiple pads, one side of the support plate resting on the first step of a staircase in the same direction of the staircase, the bottom of the support plate being connected to two pads, the two pads resting on the two steps below the first step, the multiple supports being continuously arranged along the slope direction of each staircase in the same direction.

[0008] The double-row scaffolding consists of two uprights positioned corresponding to each other in the width direction, which are erected on a support plate of a support. The top of the double-row scaffolding is covered with footboards, which are positioned directly below the upper floor of the same-direction staircase of the first floor. The double-row scaffolding is connected to the two full-span scaffolding structures.

[0009] Furthermore, guardrails are provided on opposite sides of the scaffold plank.

[0010] Furthermore, another staircase in the same direction passes through the double-row scaffolding, and the uprights at the point where the double-row scaffolding passes through are erected on the other staircase in the same direction.

[0011] Furthermore, the length of the support plate is adapted to the length of the first-level step plate.

[0012] Furthermore, the width of the support plate is adapted to be three times the width of the first step plate.

[0013] This invention provides a construction method for decorative scaffolding of an indoor multi-story cross staircase structure, comprising the following steps:

[0014] Two full-span scaffolding structures are erected on the floor of the stairwell, with the two full-span scaffolding structures respectively set on opposite sides of a staircase;

[0015] Multiple supports are continuously installed along the slope direction of each floor of the same-direction staircase, such that one side of the support plate of the support rests on the first step of the same-direction staircase of the staircase, and the two pads connected to the bottom of the support plate rest on the two steps below the first step.

[0016] Double-row scaffolding is erected on the plurality of supports, and the double-row scaffolding is connected to the two full-span scaffoldings, such that two uprights of the double-row scaffolding with corresponding positions in the width direction are erected on the support plate of one support.

[0017] Scaffold boards are laid on top of the double-row scaffolding, such that the scaffold boards are positioned directly below the upper floor of the same-direction staircase of the first floor.

[0018] The beneficial effects of this invention are that the interior multi-story cross staircase decoration construction scaffolding of this invention, through the use of a combination of supporting plates and pads for the supports, ensures that the force of the scaffolding on the steel structure staircase can be evenly distributed to each step, preventing damage to the staircase due to excessive local stress. This invention fully utilizes the convenient and free combination and erection characteristics of steel pipe scaffolding, erecting full-span scaffolding on both sides of the multi-story cross staircase and connecting them with steel pipe couplers to ensure the stability of the double-row scaffolding structure. While meeting the decoration construction requirements of a four-story cross staircase, it also ensures the safety of workers on the scaffolding. Attached Figure Description

The double-row scaffolding includes two rows of uprights and horizontal bars connecting the two rows of uprights. Two uprights 32, positioned correspondingly in the width direction of the double-row scaffolding 3, are erected on a support plate 21 of a support 2. Scaffold boards 31 are laid on the top of the double-row scaffolding 3. The scaffold boards 31 are positioned directly below the floor of the same-direction staircase above the current floor. The double-row scaffolding 3 is connected to two full-span scaffolding units 1.

[0043] S2. Multiple supports 2 are continuously installed along the slope direction of each floor of the same-direction staircase, such that one side of the support plate 21 of the support 2 rests on the first step of the same-direction staircase of a row of stairs 41, and the two pads 22 connected to the bottom of the support plate 21 rest on the two steps below the first step.

[0044] S3. Erect double-row scaffolding 3 on multiple supports 2, and connect the double-row scaffolding 3 to two full-span scaffolding 1, so that the two uprights 32 with corresponding positions in the width direction of the double-row scaffolding 3 are erected on the support plate 21 of one support 2.

[0045] S4. Lay scaffold boards 31 on the top of the double-row scaffold 3, so that the scaffold boards 31 are positioned directly below the upper floor of the same-direction staircase.

[0046] First, erect full-span scaffolding on both sides of a single staircase 41, then erect double-row scaffolding. During the erection of the double-row scaffolding, use steel pipes and couplers to secure the double-row scaffolding to the full-span scaffolding to ensure its stability.
