Introduction of shoring in construction

"Scaffolding" is a term used in the construction industry to refer specifically to the temporary support erected during the construction of a building, which is removed as the building is completed. Scaffolding is a working platform erected to ensure the smooth progress of each construction process. Different types of scaffolding are used for different purposes for different types of construction. ZEEMO scaffolding is one of the very high-quality scaffolding brands, containing many types of scaffolding. Scaffolding is widely used in construction and the following is a brief introduction to shoring in construction.

Characteristics of shoring in construction

Compared with general structures, shoring in construction has the following characteristics in its working conditions. First, the load variability subjected to is large. Second, the fastener connection nodes are semi-rigid, and the size of the node rigidity is related to the quality of fasteners and installation quality, and the node performance has a large variation. Third, the initial defects of the scaffolding structure and members, such as the initial bending of the bars, corrosion, erection size errors, load eccentricity, etc. are large. Fourth, the connection point with the wall, the constraint variation of the scaffold is large. The study of the above problems lacks systematic accumulation and statistical information and does not have the conditions for independent probability analysis, so the structural resistance is multiplied by an adjustment factor of less than 1 whose value is determined by calibration with the previously adopted safety factor. Therefore, the design method adopted in this specification is in essence semi-probabilistic and semi-empirical. The scaffolding meets the construction requirements specified in this code and is the basic condition for the design calculation.

Acceptance requirements of shoring in construction

Acceptance requirements for shoring in construction are as follows: First, the foundation treatment, method, and burial depth of scaffolding must be correct and reliable. Second, the layout of the shelf, the vertical bar, and the size of the horizontal bar spacing should meet the requirements. Third, the erection and assembly of the shelf, including the selection of the tool frame and the starting point should meet the requirements. Fourth, even the wall point or fixed part of the structure should be safe and reliable; the scissor brace and diagonal brace should meet the requirements. Fifth, for the scaffolding safety protection and safety insurance devices to be effective; fasteners and tie tightening degrees, should be in line with the provisions. Sixth, the scaffolding crane, wire rope, boom installation, etc. should be safe and reliable, scaffolding board laying should be in line with the provisions.

Precautions for shoring during construction

In the construction process, the precautions for construction shoring in construction are as follows. Missing sweeping rod, longitudinal and transverse junction is not connected, sweeping rod distance from the ground is too large or too small, etc.; scaffold plate is cracked, thickness is not enough, lap does not meet the specification requirements; there is no fall protection net between the inner riser and the wall after the removal of large template; scissor brace is not continuous in the plane; the open scaffold is not equipped with a diagonal brace; small horizontal bar spacing under the scaffold plate is too large; connecting wall pieces are not rigidly connected inside and outside; spacing of protective railing is greater than 600mm; fastener connection is not tight, fastener slippage, etc.

In recent years, the application of scaffolding has gradually become common. To ensure the quality of projects and construction safety, the company and product supervision department should keep pace with the times, make adequate risk analyses, improve inspection standards, and finally improve product quality and guarantee product safety for people to use.
