Talking about the setting of building signs

May 21, 2023

The national industry standard, the safety technical specification of the G 1302001 construction construction fastener steel pipe scaffolding edited by the Chinese Academy of Building Sciences and the Provincial Construction Engineering Corporation, has completed the expert review and was approved by the Ministry of Housing and Urban-Rural Development. In order to reflect the technical and economic policies of the fastener-type steel pipe scaffold in the design and construction, we must ensure that the technology is advanced, economically reasonable, safe and applicable, and ensure quality. The focus is on the following 10 aspects.

1 Increased scope of fastener-type steel pipe scaffolding This specification applies to floor-standing single (original), double-row fastener steel pipe scaffolding (original), full house fastener steel pipe scaffolding for building construction engineering and municipal engineering (New), steel cantilevered fastener steel pipe scaffolding (new), full house fastener steel pipe support (new) design and construction.

2 Increase the height range of fastener steel pipe scaffolding. The height of fastener steel pipe scaffolding should meet the following requirements: steel cantilevered steel pipe scaffolding should not exceed 20m; 3 new full definition of full house scaffolding and full frame support frame Scaffolding: In the longitudinal and transverse directions, scaffolding consisting of not less than three rows of poles and horizontal poles, horizontal scissors, vertical scissors, fasteners, etc., referred to as full-scale scaffolding.

Full house fastener type steel pipe support frame: In the longitudinal and horizontal directions, the implementation of a permanent signage system with no less than three rows of vertical poles and 4 knots is a powerful means to strengthen the supervision and management of project quality. And implementation is the important task of the construction administrative department at all levels and the project quality supervision organization, and the responsibility of building the main body of each party. The setting of building signs has just been fully implemented, and its standard management is in the trial stage. In general, we must grasp the principle of “economic, beautiful, durable, and true” to set up. I think with the continuous implementation of this system, the permanent signage of the building and the horizontal support, the horizontal scissors support, the vertical scissors support, the fasteners and other bearing brackets, referred to as the full hall support frame.

4 For the adjustable bracket, the screw and the supporting plate of the adjustable bracket are welded firmly, the height of the welded joint is not less than 6mm; the length of the adjustable supporting screw and the nut is not less than 5, and the thickness of the nut is not less than The design value of the 3cm. adjustable support bearing capacity should not be less than 40kN, and the support plate thickness should not be less than 5mm. 5 The load on the support frame is specified. The standard value of the live load of the personnel and equipment on the support work layer Take 1.0kN/m2, the structural components and large equipment load are calculated according to the actual calculation. The standard value of steel self-weight is 78.5kN/m3; when the support frame is used for concrete structure construction, the load standard value should conform to the current industry standard G162 building construction template safety technical specification. Provisions.

6 It is clear that the calculation of the stability calculation part of the full-stand scaffold should meet the following requirements: When the full-scale scaffolding and its supporting system are sized with the same step, vertical length of the pole and horizontal distance of the pole, the bottom should be calculated. Rod section; when the step size of the full scaffolding and its supporting system erection size, the vertical length of the pole, and the horizontal distance of the pole change, in addition to calculating the bottom pole section, the maximum step or maximum pole length must be Check the calculation of the vertical section of the distance from the distance of the pole.

The calculated length of the full scaffolding pole shall be calculated as follows: where is the step size; M is the single-bar length factor considering the overall stability factor of the full-scale scaffolding, which shall be adopted according to Table 1; k is the additional factor for calculating the length, which shall be in accordance with the table. 2 adopted.

It will become an inseparable part of the building, not only the functions of supervision, identification, decoration, but also other useful functions and functions.
