3) all municipal and district housing construction bureaus (committees), planning and Construction Commission of Suzhou Industrial Park, and all relevant units: in order to firmly implement the relevant regulations and requirements for the full use of coiled steel pipe support components (hereinafter referred to as “coiled steel pipe components”) in construction sites and ensure the safety of construction site During the construction process, the coil type steel pipe support is safe and reliable, and the supervision system for the incoming inspection of coil type steel pipe support components is established
. 
The supervision unit shall include the site acceptance and use of the coil buckle components in the supervision content, and the supervision recorder shall record the site acceptance, witness sampling, support erection and acceptance after completion of the coil buckle components, so as to comprehensively and truly reflect the site management of the coil buckle components
.
1、 Inspection report shall be provided when the turnbuckle components enter the site
.
After entering the site, the construction unit shall timely entrust a qualified testing institution to carry out sampling test
.
At the same time, the construction unit shall not use the coil buckle components provided by the leasing enterprise again
.
4、 The housing construction departments and their engineering safety supervision institutions should strengthen the on-site supervision and inspection
.
Principle of sub region and sub unit
.
If the coil fastener type steel pipe support components that do not meet the quality requirements are used, they should be resolutely ordered to leave the site
.
3
.
After the construction unit and the construction (supervision) unit witness the sampling at the construction site, the samples are sent to the testing organization for testing, mainly including the strength of the connecting plate, the compressive strength of the adjustable brace and the base, the size deviation of the steel pipe, and the mechanical properties of the vertical steel pipe
.
Local housing construction departments and their engineering safety supervision institutions should take the supervision of coil fastener components as an important part of daily supervision and inspection and safety inspection
.
Put up on site the sampling test report of coil fastener components
.
Recently, Suzhou Municipal Bureau of housing and urban rural development has issued an official notice on the establishment of the supervision system for the entry inspection of coil type steel pipe support components
.
In principle, a project uses the turnbuckle components of a leasing enterprise or a production enterprise
.
Notice of Suzhou housing and Urban Rural Development Bureau on the establishment of supervision system for the entry inspection of coiled steel pipe support components (szjz [2021] No
.
The inspection situation should be recorded and the enterprises should be urged to rectify and implement the problems
.
Spot check
.
The turnbuckle components of different leasing enterprises and different production enterprises should be strictly differentiated according to the construction area or monomer, and the mix use of turnbuckle components is strictly prohibited
.
If the quality is not up to the standard, the construction units should be urged to entrust the third-party engineering quality inspection institutions to conduct re inspection The manufacturer or leasing enterprise of coil fastener components shall be notified, and the construction unit who uses them without authorization shall be punished according to the law and regulations, and recorded in the enterprise credit file as bad behavior
.

.
Supervision and inspection
.
Sampling survey of coil fastener components after entering the site
.
3
.
The construction unit shall conduct self inspection and self correction for the coil fastener components used in the construction site, and timely find and rectify the problems according to the specifications, standards and relevant requirements
.
The sampling test report of coil buckle components shall be posted at the eye-catching position of the construction project site office
.
Supervision records
.
2
.
If there is any doubt about the quality of the coil fastener components, the construction units should be urged to entrust the third-party engineering quality inspection institutions with corresponding qualifications to conduct re inspection
.
2、 On site sampling inspection of the mobilized coil fastener components 1
.
Self inspection and self correction
.
If the construction unit uses the leased coil fastener components, the leasing enterprise shall provide the product type inspection report or test report (the test items shall include the performance, appearance and process of the raw materials), in addition to the quality assurance data such as the product certificate, main technical parameters and product instructions provided by the production enterprise for the coil fastener components of different production enterprises and different batches of the same production enterprise Dimension deviation, component strength, etc.)
.
2
.
At present, the coil type scaffold has been widely used in all parts of the country, so it is very necessary to establish the supervision system for the entry detection of support components
.
Local housing and construction departments and their engineering safety supervision institutions should strengthen on-site sampling inspection, and conduct comprehensive sampling inspection on new projects using coil fastener components from September 1, 2020 to February 28, 2021
.
After summarizing the sampling inspection results of various places, report to our bureau before March 10 (see the attached table for the format)
.
The relevant matters are hereby notified as follows
.
3、 On site supervision of coil fastener components 1
.
Attachment: summary of spot check of coil fastener components used in engineering projects Suzhou housing and Urban Rural Development Bureau on January 292021 Luban Award for Construction Engineering.
