[0022] Comprehensive Ward Building of the Affiliated Hospital of Xuzhou Medical College:

[0023] The construction area of ​​the ward complex building of the Affiliated Hospital of Xuzhou Medical College is 106939m2 2 , frame tube structure, three floors underground, twenty-two floors above ground. The construction started on April 2, 2009. The clearance of the pipe well in the bathroom is 350mm×550mm. There is one Φ160PVC drainage pipe, one Φ110PVC drainage pipe and one Φ80 water supply pipe in the pipe well. The construction surface of the pipe well is narrow, so we use GRC After the board, this construction problem was solved, which greatly accelerated the progress of the project.

[0024] The above construction method is compared with the original masonry, and the benefit analysis is carried out. The results are as follows:

[0025] Compared with aerated concrete masonry: the cost of aerated concrete block is: the area of ​​each toilet pipe well is 11.6m2 2 . per m 2 ...

[0028] Xuzhou Xinglong Building and Underground Garage Project

[0029] Construction area of ​​Xuzhou Xinglong Building and underground garage project is 42350m2 2 , frame structure, with one basement floor and sixteen floors above ground. The construction started on April 8, 2006 and was completed on November 26, 2007. The pipe well in the bathroom of this project is designed with a clearance size of 450mm×650mm, three drainage pipes in the pipe well, and the construction surface is narrow. We are using GRC panels. After the construction method, the construction problem was solved, the economic benefit was improved, and the project progress was accelerated.

[0033] Building 8, Jinxiu Jiayuan, Xuzhou City

[0034] Building No. 8, Jinxiu Jiayuan, Xuzhou City, has a construction area of ​​68,260m 2 , frame tube structure, two floors underground, 16 floors above ground in Block A, and 22 floors in Block B. Started on May 18, 2003 and completed on September 28, 2006, it is an office building. The pipe well in the bathroom of this project is designed with a clearance size of 350mm×650mm, and there are four drainage pipes in the pipe well. The original design was an aerated concrete block wall, and the construction surface was narrow. After joint research with the designer, the owner and the supervisor, we adopted the GRC board. After the implementation of this construction method, the construction problem was solved, the economic benefit was improved, and the project progress was accelerated.

Abstract

The invention mainly discloses a narrow conduit shaft wall light pre-dressing method. In the invention, the conventional on-site building block built conduit shaft wall is changed into prefabricated light glass-fiber reinforced composite (GRC) porous slat assembled wall; for avoiding a difficult conduit shaft internal wall dressing process step, prefabricated light GRC porous panels are dressed according to design requirements before installation, then welded and assembled with a main structural embedded part (or expansion bolt) on site and finally a special tool is used for jointing; and thus, design requirements are met.

Description

technical field [0001] The invention relates to a construction method for the well wall of a building pipeline well, in particular to a lightweight pre-painting method for the well wall of a narrow and small pipeline well by using GRC light porous slats as the well wall and simplifying the construction steps. Background technique [0002] With the rapid growth of the national economy, the increasing image of urban civilization and the needs of people's lives, the design standards of architectural engineering have also been continuously improved, especially for the interior decoration of public buildings, and the requirements for various parts have become more stringent, specific, detailed and civilized. For this reason, many difficulties and inconveniences have been brought to the construction. [0003] As we all know, in order to expand the usable area of ​​the house, the design of the pipe well is generally very narrow. It is suitable for plastering, whitewashing and whi...
