In the process of building construction, the edge guardrail is one of the important facilities to ensure the safety of workers. However, due to various reasons, some construction sites have problems such as non-standard installation and improper use of edge guardrails, which bring great safety hazards to construction operations. This article will introduce in detail the precautions for the installation and use of edge guardrails at construction sites to ensure construction safety.
First, the type and selection of border guardrails.
The edge guardrail is mainly divided into two types: fixed and mobile. Fixed guardrails are usually made of steel pipes, reinforced concrete and other materials, which have good stability but poor mobility; The mobile guardrail is made of lightweight materials, which are easy to move and adjust, and are suitable for different construction environments and needs. When choosing the edge guardrail, it should be comprehensively considered according to the actual situation of the construction site, the construction safety requirements and the operation habits of the construction personnel to ensure that the selected guardrail can meet the actual needs.
Second, the installation of the border guardrail.
1.Basic production.
Before installing the edge guardrail, the foundation should be made. The foundation should be flat and solid, and have a certain bearing capacity, which can withstand the weight of the guardrail and various loads during the construction process. The foundation is generally poured with concrete, and the size and depth of the foundation are determined according to the specifications of the guardrail.
2.Mounting fixtures.
For the fixed edge guardrail, it should be installed and fixed according to the design requirements. Normally, embedded parts, expansion bolts, etc. are used to fix the guardrail on the wall or column. During the installation process, attention should be paid to adjusting the position and height of the guardrail to ensure its stability and safety.
3.The connection is fixed.
The various columns and beams of the edge guardrail should be fixed with reliable connections to ensure the stability and strength of the overall structure. Commonly used connection methods are welding, bolt connection, etc. In the process of connection, attention should be paid to ensure the quality of the connection and avoid loosening or breakage.
Third, the use of border guardrails.
1.Check before use.
Border guardrails should be inspected before they are used. The inspection content includes: the appearance quality of the guardrail, the structural integrity, the firmness of the connection, etc. If there is damage or safety hazards, it should be repaired or replaced in time.
2.Regular maintenance.
In order to ensure the service life and safety of the border guardrail, it should be maintained regularly. Maintenance includes: removing dirt and rust, checking whether the connection is loose or damaged, and dealing with it in time if necessary. At the same time, the guardrail should be adjusted or reinforced as necessary according to the actual situation.
3.Use it correctly.
When using the edge guardrail, the construction workers should strictly abide by the relevant safety operation procedures and use the guardrail correctly. During use, care should be taken to avoid excessive impact or load on the guardrail, so as not to cause damage or collapse accidents. At the same time, construction personnel should strengthen their awareness of self-protection and wear safety belts and other protective equipment when using guardrails.
4. Other precautions.
1.In different construction stages, the edge guardrail should be adjusted or moved accordingly according to the actual situation. When dismantling the guardrail, it should be carried out in accordance with the prescribed procedures to avoid sudden removal or forcible dragging, so as to avoid accidental injury.
2.For mobile guardrails, attention should be paid to maintaining stability and balance during use, and avoiding tipping or tumbling. At the same time, care should be taken to avoid excessive bending or twisting of the mobile guardrail to avoid structural damage or instability.
3.During the construction process, attention should be paid to keeping the construction site clean and hygienic. Temporarily stacked construction materials, equipment and other items should be placed reasonably to avoid excessive pressure or impact on the border guardrail. At the same time, care should be taken to avoid dangerous operations or placing dangerous goods near the guardrail to avoid accidental injury.
