Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of scaffolding erection, and specifically to a construction method for erecting a scaffolding for high-rise masonry construction operations. Background Art
[0002] With the rapid development of urban architecture and the update of architectural design concepts, large-span commercial halls, hotel lobbies, sunken squares in commercial centers, and underground shopping malls attached to subway stations with storeys over 10 meters have gradually become the mainstream architectural forms and entered the public eye. To ensure the convenience and safety of masonry and plastering operations in these high-rise buildings, special operation scaffolding needs to be erected.
[0003] In traditional construction, to meet the safety specification with a height-width ratio not greater than 3, full hall scaffolding must be erected in such high-rise spaces, which not only leads to excessive resource investment but also severely restricts the working space of workers. Therefore, for the erection of scaffolding for high-rise wall masonry construction operations, it is designed to be intermittent, and the upper and lower passages are fully utilized and connected as a whole with the scaffolding as a support to meet the safety requirement of a height-width ratio not greater than 3. Compared with the traditional full hall support system, the segmented support system has the following advantages: 1. Less construction resource investment, green and environmental protection; 2. Reduced labor intensity, and the construction period can be saved; 3. Lower measure cost, which is beneficial to the turnover of construction resources; 4. Compared with the full hall erected operation scaffolding, the working space is wide, the upper and lower scaffolding passages are set more reasonably, and the construction is more convenient. It can effectively solve the problem of insufficient operation space for erecting scaffolding in halls with higher storeys, and is also more in line with green construction, achieving reduction of resource input and high efficiency of resource utilization. Summary of the Invention
[0004] In view of the above-mentioned prior art, the present invention proposes a construction method for erecting a scaffolding for high-rise masonry construction operations.
[0005] A construction method for erecting a scaffolding for high-rise masonry construction operations provided by the present invention includes the following steps: S1. Use a theodolite to measure and set 300 mm outside the building and wall sidelines as the sidelines for scaffolding erection; S2. Install the vertical poles, horizontal bars, diagonal bars, and walkway boards of the first row of the scaffolding close to the building to the required height. To ensure the required working space, no horizontal bar is set at 1.5 m above the walkway board of the first row close to the working edge; S3. After the first row of the scaffolding is completed to the required height, every third span of the second row of the scaffolding is erected for one span; S4. Erect the third to the nth row of the scaffolding and so on until the last row of the scaffolding is not more than 4 m, and there is no need to erect the next row of the scaffolding; S5. According to the requirements of on-site construction, a sufficient number of movable up and down passages shall be set up, and according to the requirements of convenient construction operations, the frames outside the second row shall be replaced with up and down passages, and the up and down passages shall be connected to the frames with steel pipe fasteners as lateral supports; S6. Monitor the displacement and settlement of the intermittent frame during its use.

DETAILED DESCRIPTION
[0013] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

In order to ensure the required space for operation, no horizontal pole is set at 1.5m on the walkway board 5 of the first row near the operation side; S3, after the first row of frames 8 is completed to the required height, the second row of frames 9 is erected every three spans, and the height is 2 / 3 of the height of the first row of frames; S4, erect the third row of frames 10, the height of which is 1 / 3 of the height of the first row of frames and is not greater than 4m; S5. According to the requirements of on-site construction, a sufficient number of movable up and down passages shall be set up, and according to the requirements of convenient construction operations, the frames outside the second row shall be replaced with up and down passages, and the up and down passages shall be connected to the frames with steel pipe fasteners as lateral supports; S6. Monitor the displacement and settlement of the intermittent frame during its use.
[0015] Among them, the horizontal and vertical spacings of the uprights 2 of the frame are both 1200mm, the diagonal rod 4 is set every three spans, the walkway board 5 is laid one layer every 2m from the ground, and at the same time, a 200mm high skirting board 6 is set at the laying place of the walkway board 5 as hard protection, the height of the sweeping rod is 500mm, and an adjustable base support 1 is set at the lower end of the frame. The length of the adjustable base support 1 inserted into the upright 2 is 150mm, and the gap between the upright 2 and the adjustable base support 1 is 2.5mm.
