Case sharing and teaching method of carbon emission calculation in demolition stage: this training adopts online method, with a total of 6 class hours and 2 lectures.

There are few original cast-in-situ operations on site, and the health does not disturb the residents.

Although they look very simple, accurate data are needed to ensure the success of splicing, so they also need to be extra careful in drawing*** * * * * * * carbon emission calculation – only dry goods: calculation method of building carbon emission 1 Key points, basis, boundary and regulations of building carbon emission calculation; 2.

From then on, we bid farewell to “gray”.

In the whole construction process, these small precast slabs are the most important.

The finished cast components are loaded on the road and transported to the site.

Through the reflection principle of the small dressing mirror, it is convenient to plug the reserved reinforcement in the lower layer into the hole of the upper cast column.

It is conducive to regulating the supply relationship, improving the listing speed of real estate, slowing down the current situation of insufficient market supply, and there is no need to queue up all night to buy a house.

The progress of precast buildings is about 30% faster than that of traditional methods.

How is the most important lifting step operated? The dressing mirror in the figure above is prepared for the hoisting of the cast column.

“Assembly” is not just “erection”.

It is conducive to accelerating the progress of the project, and the efficiency is return.

How are cast components produced? Taking the cast building board as an example, the production process is: steel formwork fabrication → reinforcement binding → concrete pouring → demoulding.

Holes shall be reserved during reinforcement binding.

The hoisting of cast composite beam and cast composite plate can also be pre assembled on site or build a cast exhibition area for the parts with great hoisting difficulty.

The construction process takes the precast frame structure as an example.

The precast components are precast in the factory, which can maximally improve the common quality problems such as wall cracking and leakage, and improve the overall safety grade, fire resistance and durability of the residence.

Hyaluronic acid, which is conducive to improving the construction quality of the construction industry, can make the construction products long-term and young.

It is conducive to improve the construction quality.

It is conducive to civilized construction and safety management.

There are a large number of workers on the traditional operation site.

Four popular calculation methods: the whole process of building carbon emission calculation 1 Calculation of carbon emission in the production and transportation of building materials; 2.

After the pre assembly of the girder of the frame structure and the hoisting of the exhibition area of the shear wall residence, bind the reinforcement of the cast-in-situ layer and prepare to pour the concrete of the cast-in-situ layer.

Concrete pouring and assembly line operation.

After the construction of the first floor, the columns of the upper floor are hoisted first, and then the main beam, secondary beam and floor slab are hoisted.

In order to ensure the smooth lifting, after the cast components are transported to the site, the stacking site needs to be reasonably arranged to facilitate the lifting.

Therefore, such “industrialized” and “industrialized” buildings have been widely used in Europe, America and Japan.

It is conducive to environmental protection and resource conservation.

When binding reinforcement, the hook shall be embedded in it.

After the indoor fine decoration is industrialized, express delivery can be received at home, which can be disassembled and installed quickly and well.

In order to increase the connection between the cast members and the cast-in-situ layer and ensure the reliability and safety of the structure, the surface of the cast members are left with keyways or roughened.

Then fill, and finally add sealing strip caulking glue.

********************************************************************************* What are the advantages of precast buildings? Why are these developed capitalist countries so keen on precast buildings? The reasons are as follows: 1.

What is a precast building? What are the advantages? How are precast buildings produced? How is the site constructed? Xiaobian takes you to understand.

In addition, the reuse rate of steel formwork can be improved, and garbage, loss and energy saving can be reduced by more than half.

4.

Compared with traditional construction methods, precast buildings can not only be faster and more convenient, but also save manpower and materials.

Now, a large number of site operations are moved to the factory, and only a small number of workers need to be left on the site, which greatly reduces the incidence of on-site safety accidents.

After the hoisting of precast components is completed, the reinforcement at the connection part shall be bound, and finally the joint and the cast-in-situ layer of beam and slab shall be poured.

Just like moving, we usually arrange the goods handling sequence to reasonably reduce the workload.

After demoulding, the finished cast plates and cast components are cast and temporarily stacked in the factory, which can be ready to be transported to the construction site.

After the popularization of the industry, the construction cost can be reduced and the house price can be effectively restrained.

6.

After the precast components are transported to the construction site, the reinforced concrete will be overlapped and poured, so the assembly room is very safe.

First of all, on the exterior wall, there is this lock type splicing method, and some are butted with reinforcement skeleton.

At present, the floor slab is usually in the form of 7 + 8 (70mm thick precast floor slab + 80mm thick cast-in-situ layer)..

There are various connection modes between cast components.

5.

Therefore, it is not unreasonable for the state to promote precast buildings.

The lower space is narrow and inconvenient to observe.

What is a precast building? Like Lego, a precast building precast some or all components in the factory and then transported to the construction site for assembly.

When constructing the interior wall, first install the skeleton, and then directly splice it, which is convenient and fast, and also convenient for subsequent demolition and modification.

What is the most technically demanding of the above steps? The answer is the hoisting of cast components.
