Is it safe to cast in place partition construction, duplex compartment cast in place?

Cast-in-place reinforcement process.

The new technology of planting reinforcement is to use high-strength chemical adhesives to make steel bars, screws, etc. and concrete produce a holding force, so as to achieve the reserved effect steps: positioning--- drilling--- dust removal--- glue injection--- implanting steel bars--- curing steel bolt anchoring method.

1.Before the construction preparation, the design and construction drawings should be carefully read, and the structural surface must be cleaned up, and the drilling position of the reinforcement anchorage point should be marked according to the design drawings and the drilling position should be marked by the person in charge of the site.

2.The drilling hole clarifies the bolt anchorage position, hole diameter and anchorage depth according to the requirements of the design drawings.

3.Hole cleaning. 1）.

After the drilling is completed, the dust is cleaned up within the radius of the hole within the meter range, and the hole is cleaned with an air pump and a brush, and this process should be done to three blows and two brushes, that is, three blows and two brushes, and after the brushing is completed, the inner wall of the hole is cleaned and dried with cotton silk dipped in acetone, so that the hole is finally clean and dry; In case of humidity, it is necessary to use a heating rod to dry it.

2）.If it is a water borehole: wash the mud in the hole with clean water, wipe the hole with cotton silk, and then carry out the next process after the hole is dried.

3）.Use clean cotton silk to tightly seal and plug the cleaned holes to prevent dust and foreign objects from falling in.

4）.The person in charge of the site inspects the hole cleaning work, and asks the general contractor and the supervisor to accept and make a record of the hidden inspection.

4.Rebar cleanup.

1）.Mark the corresponding position at the end of the steel bar to indicate the length range of rust removal and cleaning; This length range is required to be greater than the required anchorage depth of 50mm.

2）.Start the grinder and use a wire brush to polish the surface of the steel bar within the length of the derusting and cleaning until it has a metallic luster.

3）.Put the derusted and cleaned steel bars in a dry place and stack them neatly.

4）.Use cotton silk dipped in acetone to wipe the surface of the steel bar within the length of the rust removal cleaning.

5）.Put all the processed steel bars neatly and report to the person in charge of the site for inspection.

5.Rebar embedding.

1）.Preparation of glue for reinforcement anchorage. (Please refer to the corresponding product description for the specific ratio and use method, or follow the requirements of the person in charge of the site) Requirements: Prepare in proportion and stir evenly.

2）.If it is a blind hole steel bar embedded: the anchoring can be injected into the hole with glue 2 3; Slowly insert the treated steel bar into the hole while rotating in the same direction until it reaches the bottom of the hole.

At this time, if there is no anchoring glue overflowing from the hole, it means that the amount of glue injection is not enough, and the steel bar must be pulled out, re-injected, and re-inserted until the glue can overflow out of the hole.

3）.If it is a through-hole steel bar embedded: first insert the treated steel bar into the hole, and the two ends of the hole are blocked with epoxy mortar, and when plugging, the glue injection hole must be left at one end, and the air outlet hole must be left at the other end; After the epoxy mortar is solidified, high-pressure glue injection can be carried out.

Load the prepared anchoring glue into the gluing cartridge and install the gluing nozzle; Inject the anchoring glue into the hole through the glue injection hole until the glue overflows from the air outlet at the other end; Then, use epoxy mortar or other materials to seal the injection hole and the air outlet.

In the decoration of duplex houses, residences with higher floor heights than normal floors, and buildings that need to add compartments, the construction methods that need to add compartments are: reinforced concrete cast-in-situ floor slabs, cast-in-situ or laid steel plates for steel structure foundation skeletons, and steel structure partitions plus multi-layer boards or wooden boards.

Advantages of cast-in-place floor slabs:

1.Compared with cast-in-place floor slabs and prefabricated floor slabs and steel structure partitions, they can enhance the integrity of the house, good seismic resistance, durability, stiffness, and have greater bearing capacity, and also have certain advantages in heat insulation, sound insulation, waterproofing, etc.

2.Practice has proved that cast-in-place floor slabs can adapt to building planes of various shapes, and it is relatively more convenient to leave holes, openings or set embedded parts.

3.The reason why people like this cast-in-place method is also that: the thickness of the separator made is moderate, the upper and lower parts are completed at one time, and the concealed projects involved such as water and electricity pipelines can be pre-embedded, and there is no need to slotte to destroy the building structure in the later stage, and the stability is relatively good.

4.Cast-in-place floor slabs are permanent and generally have a service life of 70 years.

This way of constructing the compartment itself has proven to be safe.

Properties of cast-in-place floor slabs:

The duplex cast-in-situ floor slab partition is equivalent to the secondary structure construction on the original building structure, so all the processes of cast-in-situ must be carried out in accordance with the requirements of the process specifications and the drawings, and it is absolutely impossible to cut corners, which is necessary to ensure safety.

In the duplex compartment to take the way of implanting steel bars, in order not to destroy as much as possible, the load-bearing structure of the original cast-in-place ring beam starts, and the steel bars are implanted on the ring beam of the original building for cast-in-situ, or there is a considerable part of the load-bearing, which is built on the ring beam, so the firmness of the in-situ casting of the partition in this way is quite good. In the early stage, the configuration of steel pipes, laying slabs and steel bars, etc., in fact, the final maintenance is still very important. If the maintenance fails, or the concrete solidification time is not enough, if the mold is removed in advance, the most intuitive load-bearing performance of the concrete is reduced, that is, many cracks appear; Therefore, the later maintenance should not be ignored.

If the house does not meet the requirements, you can choose to build a steel structure to build a partition, after all, compared with safety, poor sound insulation is also acceptable. Finally, the cast-in-place compartment is related to the load-bearing of the house, and it is important to find an experienced master.

It is also relatively safe, because the current process and materials are relatively safe, and the process has been improving.

The duplex compartment is cast-in-situ safe, and has now passed the acceptance of the relevant state departments. This way of building a house can not only save costs, but also be safer and more secure than the traditional way of building a house.

Duplex partitions are safe to be cast in situ because they can only be poured after the house has been built to maintain the stability of the walls.

I think it's still relatively safe, because this kind of technology is still relatively advanced at the moment.

Detailed steps of cast-in-place partition construction.

Now the cast-in-place construction process can often be seen in more and more house construction, and the most critical link to do cast-in-place partition is planting reinforcement. Let's take a look at the construction steps of the cast-in-place compartment with side noise:

1. Slotting: Before slotting, the height and dust width of the wall slotting should be measured, and there should be no burrs in the trough;

2. Installation of the formwork: In the process of installing the formwork, there should be more supporting steel bars, and the surface should be smooth and uneven;

3. Groove drilling: between 12cm-14cm of the required distance of groove drilling, remember to rinse with water after the drilling is completed, and then punch into the planting glue;

4. Rebar binding: In the process of rebar binding, the wiring should be considered to pave the way for the wiring of the wire line in the future;

5. Pouring concrete: choose cement with quality assurance, try not to use sea sand, you can choose Yellow River sand. It is necessary to ensure that the thickness of cast-in-place concrete shall not be less than 10cm;

6. Compacted concrete: use flat plate vibration to make the surface smooth and flat.

7. Watering and maintenance: When the temperature reaches more than 20, it is required to water and maintain every day, and then dismantle the formwork after a week; If the temperature is low, you can water it once every two days, and then remove the formwork after half a month.

Therefore, over the years, Baoshi Construction has won a good reputation in the industry with excellent professional and technical force and excellent construction personnel! We have achieved results in various medium-sized communities in Fuzhou, and many of them are under construction for housing renovation.

Safe. Normally, the use of cast-in-situ floor slabs in duplex buildings is also relatively safe, and now the house built by the developer must meet the standards in all aspects, and will be accepted before delivery, and only the house that passes the acceptance can be delivered normally. Duplex buildings are generally relatively high, but also belong to the two-storey building, the general height of the house is required to reach more than five meters, between the two floors will be directly installed a staircase, up and down the stairs is also more convenient.

Duplex buildings are generally made of double-layer two-way steel bars, so that the load-bearing capacity is relatively strong.

1. The corner fixing should be done by planting reinforcement, and the main beam should not be easily damaged.

2. The steel bar must be made of national standard ribbed steel and bundled into a net with two or four layers at an interval of 150-200mm

3. Select qualified cement products and river sand. (Cement 425 600 mark, river sand, mountain stone, the ratio is 1:2:3 Stir well, and shake with a special vibrator.) Adopt rebar planting).

4. The post-maintenance of the floor slab should be sufficient. (It is recommended not less than half a month) 5. When the span is too large, a professional civil engineer must be asked to calculate it to avoid danger caused by excessive weight.

6. The reinforcement should be reasonable. As long as the design of concrete floor reinforcement is reasonable, even if there are major changes, I hope it can help you, thank you.
