What are the precautions for building a formwork installation
The interior of the formwork shall be cleaned
Sundries left in the formwork will cause defects such as slag inclusion in the concrete. If the aluminum formwork is used, which can be recycled many times, some concrete blocks will stick to the aluminum formwork after repeated casting. If it is used without cleaning, the concrete after casting will become bumpy. Therefore, the residual concrete blocks on the aluminum formwork shall be removed in time.
Make preparations for embedded parts and pre-buried holes
When supporting the building formwork, the embedded parts and pre-buried holes on the building formwork shall be fixed at the same time. The embedded parts and pre-buried holes shall not be left, the dimensions shall meet the requirements, and the installation shall be firm. At the same time, different formworks have different ways of installing embedded parts and pre-buried holes. Wooden boxes are nailed on the floor slab for the construction of wooden formworks to pre-buried floor holes. However, this method is not feasible in the construction of aluminum formwork, and it is difficult to fix the casing or pre-buried hole model on the aluminum formwork. As the assembly of aluminum formwork is a programmed assembly, it is not allowed to open holes on the formwork at will.the pre-embedding of the wire box and the wire pipe must be planned and designed in advance, and the position and direction must be accurate.
Pay attention to the selection and use of formwork release agents
When selecting the formwork release agents, select the release agents that do not affect the structure and hinder the construction of decoration works. At the same time, since the formwork release agent may pollute the joints between the reinforcement and the concrete, it may have an obvious adverse effect on the mechanical performance of the concrete structure. As a result, it shall be avoided polluting the reinforcement during brushing.it is also necessary to brush a sufficient amount of formwork releasing agents. If the formwork release agents are not brushed enough, a large amount of concrete will stick to the formwork. It should be noted that the formwork release agents may be washed away after rain, so it must be ensured that the release agents are brushed in place before casting.
Panel joints need to be tight
If the joint of the building formwork is not tight, it will lead to the leakage of the concrete. The leakage of concrete will result in the honeycomb surface of the concrete appearance and directly affect the quality of the concrete.no matter what materials of formwork are used, the joints shall be tight. It is worth noting that the aluminum formwork has few joints, high precision and good concrete surface effect after formwork removal. After the aluminum formwork is removed, the concrete surface quality is flat and smooth. There is no need to plaster, resulting in making construction more cost-effective.
The floor shall have enough support force
For a multi-layer cast-in-place structure, the upper building formwork must be supported on the lower concrete slabs. There are three points for attention. First, the lower concrete floor shall have sufficient bearing capacity, and support shall be added if necessary. Second, the columns of the upper and lower supports shall be aligned. Third, the base plate shall be laid under the column of the support.
Easy causes of aluminum formwork damage
Use a hammer to knock on the aluminum formwork when cleaning
Reason:
– Using poor quality roller oil or less oil makes the concrete stick more on the surface of the aluminum plate, workers use a hammer to clean the concrete.
– Workers use hammers during use
Consequent:
– The aluminum plate surface is concave, affecting the aluminum sheet structure, leading to irreparable and compensation (if any), especially at the corner of the aluminum formwork.
Solution:
– For the case of adhesive concrete: The contractor needs to strictly manage the oil rolling of workers.
– Good roller oils should be used to protect the formwork for a long time.
– Need to buy tools used to pry formwork to avoid using hammers.
– Do not use a hammer to knock directly on the aluminum surface during use.
Use a hammer to knock on the aluminum formwork plate when erecting:
Reason:
– The floor is run from 1-3cm, the last plate cannot enter.
Consequent:
– The aluminum plate surface is concave, affecting the aluminum formwork sheet structure, leading to irreparable and compensation (if any), especially at the corner of the aluminum sheet.
Solution:
– For the case of floor running: Do not use a hammer to knock on the surface of the aluminum formwork sheet.
The aluminum plate falls freely when removing the aluminum formwork
Reason:
– In the process of removing the formwork, the contractor does not use the method of spreading the net to protect the formwork (mainly beam and floor formwork).
Consequent:
– When removing the aluminum formwork panels, they overlap, causing it to be punctured, broken hip leading to irreparable damage and must be compensated (if any).
Solution:
– The Contractor should have a net or other measure to prevent the aluminum formwork from falling freely.
Cut steel on the floor by welding machine or rock wind
Reason:
– Cutting holes through the floor, steel beams, wrong floors…
Consequent:
– When cutting, welding or rock wind falls to cling to the surface of the aluminum formwork sheet, plus the water will be oxidized for a long time, it will be damaged by the aluminum formwork sheet, leading to irreparable and compensation (if yes).
Solution:
– Contractors should not cut steel with welding rods, wind and rocks.
– Take measures to cover the aluminum surface before cutting.
Drill holes to catch the bass reinforcement ME . box
Reason:
– The contractor for the ME subcontractor drilled the aluminum trunk plate too much to fix the ME box reinforced bass plate.
Consequent:
-Drilling a lot and the hole is too big will not be repaired and must be compensated (if any)
Solution:
– Coordinate with ME contractor to find a way to position the ME box without screws.
– If it is necessary to drill holes, you must find a way to mark and locate the aluminum formwork that has been drilled, so that the next floor does not have to generate additional holes.
Cut the formwork hole by welding machine or rock wind
Reason:
– High-transmission surveying unit, 10mmmm screw to reinforce ME box, floor vent gel box.
Consequent:
– Damaged plate cannot be repaired and must be compensated (if any)
Solution:
– Contractors should prohibit workers from modifying welding machines or rock wind to cut aluminum formwork.
– The high-level transmission floor vents need to have measures to position the plate so as not to cut or punch many holes.
The most traditional wood template, more common is the poplar wood template and pine template. These templates are relatively light and low cost, but the durability is not very good, and the reuse rate is very low
Steel template, as the name suggests, is of steel, with very strong strength, but it is overweighted, reusable and costly.
Plastic template, not afraid of water, low cost, durable, but the strength is not enough
