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.

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

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

Graphic analysis of the whole process of precast building from production to construction # what is precast building? What are the advantages? How are precast buildings produced? How is the site constructed? Xiaobian takes you to understand.

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

It is conducive to accelerating the progress of the project.

Prefabrication rate = total volume of cast members ÷ total concrete volume..

It is conducive to improve the construction quality.

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.

It is conducive to environmental protection and resource conservation.

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.

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

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

02.

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

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.

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

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.

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

There are various connection modes between cast components.

Construction process} take the precast frame structure as an example.

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

Efficiency is return.

They all have their own unique ID number to facilitate seating.

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

What is a precast building? Just like Toledo, a precast building prefabricates some or all components in the factory and then transports them to the construction site for assembly.

03.

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

Precast buildings have two important indicators, the proportion of assembly area and prefabrication rate.

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

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

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.

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.

Hyaluronic acid, which is beneficial to improve the construction quality and the construction industry, can make the construction products lasting and young forever.

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

Concrete pouring and assembly line operation.

Walls, slabs, stairs and other cast components have their own unique numbers.

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

05.

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

Assembly rate = implemented assembly area ÷ total floor area.

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.

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

“Assembly” is not just “erection”.

Cost control cost control and design management are the finishing point of the implementation process of precast buildings.

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.

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.

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

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

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.

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.

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

The lower space is narrow and inconvenient to observe.

Taking the connection node of primary and secondary beams as an example, this paper shows the diversity of connection methods between cast components: the connection edge node of primary and secondary beams – the connection middle node of primary and secondary beams with reserved notches on the main beam – the connection node of primary and secondary beams with reserved post cast sections on the main beam – how can so many components with corbel on the main beam not make mistakes? That is to number the assembled components! In order to ensure that workers will not make mistakes, reduce construction errors and speed up the progress of the project, each component is provided with an ID card.

How are cast components produced? Take the process of demoulding → fabrication of steel formwork → assembly of steel slab as an example.

It is conducive to civilized construction and safety management.
