About Building Construction Safety Supervision Measures
Promote the progress of science skills to enhance the skills of building construction, continuous improvement in the quality of the project also found a lot of new questions. Work place safety supervision of construction process is ubiquitous question, making accidents continue to occur. Combined with the actual situation, we must continue to strengthen safety supervision measures, in order to actively improve the quality of the project, to ensure the construction operation is completed within the stipulated time, and create greater economic benefits for the construction units. In order to maintain the safety of construction projects in the construction process must strengthen supervision of work safety in construction.
1, the load-bearing frame aspect of supervision template
1.1 review the construction program for review of the construction program, we must do all aspects of the view, the primary material specification contains templates and support systems, joint method, internal structure, horizontal bar, etc., which are reviewed one by one according to the needs of the construction drawings.
Pole at the bottom of the upper support structure required to achieve the support load requirements; template pole construction to withstand the load, should remain two or more columns, add a column at the bottom of the needs of wood pallets, do not allow the use of brick and brittle materials bedding; with regard to maintaining the firm as a whole column, add device support pillar in the process and the level of demand scissors; after setting pole height 2m beyond the level of support the needs of two; the level of a full house template should be reinforced to support the pole set on four sides and center of every pole bracket Add a longitudinal cross-pole four-scissors; pole after every increase of 1.5m ~ 2m need to add a level of support; accurate accounting of the column spacing, the use of quasi-48 steel pipe from the need to control time within 1m?.
1.2 View formwork of steel, fasteners construction process, the choice of steel tubular support system must be based on the specific circumstances, some cases are not allowed to use such a structure, such as: formwork height greater than when 8m, span greater than 18m, total construction loads greater than 10kN / m2, concentrated line loads exceed 15kN / m, which must be adopted to stop fastening steel support system, you can choose the steel columns, steel brackets and other system instead. In the erection of the template used in load-bearing steel frame, fasteners shipped to the construction site in the future, should the material sample to see, when there is abnormal test should be timely rectification reinforcement.
1.3 Quality control erection erection quality directly affects the entire building construction science, construction should be timely and perfect before and after erection work. Quality control is usually adopted when the erection methods include: erection professional level view of the operator; see the erection can meet the engineering design requirements; View pole, sweeping bar, horizontal bar, scissors and other specific parts of the erection and the number and specification is not consistent, if found to need further review in accordance with the different drawings.
2, scaffolding safety supervision
When the erection of scaffolding erection aspects of demand combined with 2.1 specification developed by the construction program, a good erection after design work must be handed over to the unit responsible person in charge of marking signed and submitted to the responsible person in charge of the project to see the acceptance, when determining program eligibility to invest in the future specific operation. Scaffolding support system should be solid and reliable, if encountered some large areas of support bent, the special needs of developing construction design, construction specifications and reference erection operations. Erection early demand for specific materials stern view erection, erection of structural stability concerns, review the primary focus of the force components for steel, fasteners, etc., in order to ensure that the future structure of the carrying capacity of the construction and load size. Subject to safety skills sector construction units listed reinspection after erection work is completed before use.
Put into use after 2.2 use of scaffolding, the master node to stop longitudinal, transverse horizontal bar, sweeping bar, even the removal of the wall components, and good fastness to view their connection, be sure to set and connecting rods, and even wall pieces, support , openings and other internal structures truss construction specifications can be achieved. In addition, demand for water adhere to the foundation, many aspects of loose base, pole and other questions dangling. Good security measures and avoid overload occurs when using scaffolding. Settlement and vertical deviation degree beyond 24m height scaffolding pole should viewer is not within specifications.
2.3 After construction demolition aspect needs to be timely removal of scaffolding, demolition process should be conducted in a certain order, usually from top to bottom and gradually dismantled. Meanwhile, even the wall pieces, also needs to follow a common dismantle scaffolding, it can avoid the other after the removal of the scaffolding loose. Members were removed after throwing altitude stop demolition process should be set by the person monitoring the security warning area.
3, construction safety supervision machinery
3.1 crane crane prime viewing areas when it comes to building included: stopper, insurance device, torque limiter device attached to the wall with the track roadbed, track pliers and other contents of the folder structure. When viewing a demand to ensure that the crane torque limiter, since the integrity of the different travel limit switch devices used in weight limiters configured settings are not in a normal state, and to maintain the integrity of these components, with no free entry operation. When using a crane, the demand for environmental supervisors seek command operations and strengthen different aspects of view, to ensure that the crane can achieve operational requirements demand.
3.2 material hoist materials hoist prime viewing areas are: aircraft-manufacturing, the frame body stable, many aspects of rope, equipment inspection, aircraft and the like. Enhance the rope to stop the connection, tip and reel with strong demand for the roll should refer to the order; the lowest position when the job reaches the basket, keeping the rope reel up more than 3 laps; add hoist dock safety equipment needs, port dock floor railing and other related equipment; rack and rack attached to the wall of the body, such as construction, demand combined with rigid parts connected, and maintain the stability of structures, connect it to stop on the scaffold; strict accounting of wind cable hoist rope length , the material must use steel wire; when the hoist height of less than 20m, wind cable rope required beyond a group; hoist height when in 21m ~ 30m, required to go beyond the two groups; the hoist use process, should ensure that the material in evenly distributed within the basket, stand up long expected to make use of anti-rolling process method to avoid overloading.
4. Conclusion
In summary says, strengthen safety supervision in construction is not lack of jobs, which each link supervisors needs to be controlled, so you can ensure the smooth conduct of the construction process, the elimination of all kinds of accidents and adverse effects of the accident the probability is reduced to a reasonable level to ensure smooth implementation of the project.
