Source: Notice on strengthening safety management of formwork support and scaffold engineering at construction site issued by Suzhou Municipal Bureau of housing and urban rural development (No.26 [2020] of Suzhou Municipal Bureau of housing and urban rural development) proposes: from January 1, 2021, All newly started housing construction and municipal infrastructure projects shall use socket type and disk buckle type steel pipe supports
.
The quality of all types of scaffold materials must meet the requirements of corresponding specifications and standards
.
Otherwise, once found, the qualification of applying for all kinds of excellent and advanced evaluation of the project will be cancelled, and the rectification will be stopped
.
Recently, Suzhou Municipal Bureau of housing and urban rural development has issued two relevant documents, one is the “Circular on the special inspection of the use of coil type steel pipe support components in municipal housing projects in 2021” and the other is the “notice on information collection of coil type steel pipe support components”
.
As for circular 1, there are 20 projects under construction inspected this time, and the construction units mainly have the following problems: some construction enterprises use the turnbuckle components of multiple production enterprises, which are not strictly divided by regions, and there is a phenomenon of mixing turnbuckle components of different leasing enterprises or production enterprises; Some construction enterprises did not collect all the quality assurance data of coil fastener components from multiple production enterprises, and only collected the quality assurance data of one production enterprise; Some construction enterprises did not post the sampling test report of coil fastener components on the construction site
.
2、 One project was praised and two projects were criticized: (1) publicized praise 1
.
Project name: new collaborative innovation industrial park high standard workshop, talent apartment and supporting housing project 1 # – 4 # – Project (2) publicized criticism 1
.
Project name: clothing factory reconstruction and expansion project 2
.
Project name: New Taicang rescue management station project of Civil Affairs Bureau 3
.
Next key work: 1 Strengthen the rectification of mixed use of turnbuckle components, and strengthen the handling of unclear identification of turnbuckle components
.
The construction unit and the supervision unit shall immediately organize personnel to sort out, and different manufacturers shall provide relevant quality assurance information respectively
.
For the coil buckle components that the leasing enterprise fails to provide quality assurance information, they shall be removed from the site
.
If the source cannot be explained or the supporting data are not provided, all the coil fastener components will be removed from the site
.
2
.
For the new projects started on June 20, the construction unit is strictly prohibited to lease the coil fastener components whose product identification does not meet the requirements
.
3
.
The supervision unit should use the supervision recorder to strengthen the examination of the information of multiple links of the coil buckle components
.
The unqualified coil buckle components are not allowed to enter the construction site
.
If the supervision unit fails to implement the relevant standard requirements or the implementation is not in place, credit points will be deducted
.

Attached two original texts: Circular of the Municipal Bureau of housing and urban rural development on the special inspection of the use of coil type steel pipe support components of municipal housing projects in 2021 (szjz [2021] No.15) all municipal and district housing and urban rural development bureaus (committees), planning and Construction Commission of Suzhou Industrial Park, all relevant units: in order to strengthen the quality management of coil type steel pipe support components at construction sites, From March 31 to April 2, 2021, the Municipal Bureau of housing and urban rural development organized and carried out a special inspection activity on the use of coil type steel pipe support components in municipal housing projects
.
The relevant information is reported as follows: 1
.
Overall situation: 20 projects under construction were inspected this time (2 in each region)
.
According to the “special checklist for the use of coil type steel pipe support components in Suzhou Municipal Housing Engineering”, the supervision, site management and quality assurance data of coil type steel pipe support components are mainly checked
.
In this inspection, 19 batches of coil fastener components (except for Taicang rescue management station project newly built by Taicang Civil Affairs Bureau) were randomly inspected, and a rectification notice was issued
.
2、 Main problems (1) construction units
.
Some construction enterprises use the turnbuckle components of several production enterprises, which are not strictly divided according to the region, and there is a phenomenon of mixing turnbuckle components of different leasing enterprises or production enterprises; Some construction enterprises did not collect all the quality assurance data of coil fastener components from multiple production enterprises, and only collected the quality assurance data of one production enterprise; Some construction enterprises did not post the sampling test report of coil fastener components on the construction site（ 2） Leasing enterprises
.
Some leasing enterprises provide the coil fastener components of multiple production enterprises, but only provide the quality assurance data of one production enterprise; Some leasing enterprises provide coil fastener components of different production enterprises without obvious identification; Some leasing enterprises do not provide or provide the main technical parameters and product instructions do not meet the requirements（ 3） Supervision enterprises
.
Some supervision enterprises do not use the supervision recorder or the supervision recorder does not record the entry acceptance, witness sampling, support erection and acceptance after completion of the coil fastener components; Some supervision enterprises did not strictly check the entry acceptance of coil fastener components, and did not carry out the acceptance in accordance with the documents and relevant specifications of the Municipal Bureau of housing and urban rural development（ 4） Testing institutions
.
The testing reports issued by some testing institutions lack the testing basis of GB / t228.1; The information of leasing enterprises is not stated in the testing reports issued by some testing institutions; The mechanical property testing basis of some testing institutions is inconsistent (welded steel pipe for general structure and low alloy high strength structural steel); The testing reports issued by some testing institutions lack the items such as the compressive strength of adjustable braces and bases, the size deviation of steel pipes and the mechanical properties of vertical steel pipes
.
3、 Project Name: new collaborative innovation industrial park high standard workshop, talent apartment and supporting housing project 1-4 project, construction unit: Jiangsu Huifeng construction and Installation Engineering Co., Ltd., project manager: Xu Bin; Supervision unit: Jiangsu Changcheng construction consulting Supervision Co., Ltd., director: Qu Xuefeng（ 2） Project Name: Reconstruction and expansion project of garment factory, construction unit: Zhangjiagang Houcheng construction and Installation Engineering Co., Ltd., project manager: Tang Yue; Supervision unit: Jiangsu Huatong Engineering Management Co., Ltd., director: Chen Jiming
.
The local safety supervision organization has been required to issue a rectification notice
.
Main problems: the content of the product certificate of coil fastener components does not meet the provisions of article 8.1.2 of JG / t503-2016, and there are many missing items; The manufacturer did not provide technical parameters and product instructions; The inspection items of type inspection report are lack of appearance quality and dimension measurement content; The supervision unit did not use the supervision recorder; The product model on the surface of coil fastener component is not identified according to Article 4.3.1 of JG / t503-2016; Two manufacturers of coil fastener components were used on site, but no relevant quality assurance data of Wuxi Xicheng special thin plate Co., Ltd
.
was found
.
Some horizontal bars used on site were made by the construction company, and coil fastener components from different manufacturers were mixed; The test report lacks the test basis of GB / t228.1, and does not contain information such as leasing enterprises
