This is the load-bearing wall, non load-bearing exterior wall and non load-bearing exterior wall.

In fact, the core purpose of these policies, including those of all provinces, is a target requirement.

Another key is to increase the thickness.

All schools and hospitals adopt precast buildings.

You can’t miss these wonderful moments…

Precast concrete exterior walls and interior walls are difficult to apply, because the key is that the equipment investment is large, the production efficiency is low, the comprehensive cost is high, and the market is difficult to accept.

we are very willing, that is, the production equipment and technology are very simple, Therefore, the cost is very low, which is much lower than that of cast-in-situ.

Combined with the situation of Shandong, the solid waste related to construction in Shandong is mainly coal gangue.

We have made great adjustment and innovation in the installation process.

Overall, more than 50% must be met.

Virtually, 3 cm more concrete is used.

One is qualified.

The other is the reinforced truss floor slab.

After arriving in China, Our buildings are mainly high-rise buildings, including the county.

Now the houses developed are 20 or 30 storeys.

After the assembly rate reaches 50 points, it is qualified.

On December 27, 2022, the 2021 national solid waste recycling and comprehensive utilization technology conference with the theme of “recycling leads the future and regeneration helps double carbon” was held in Jinan.

The so-called horizontal construction is the precast stairs, air-conditioning panels, balconies, etc.

The building assembly rate scores.

There are only one star, two star and three-star, which can be selected.

The current target requirement is affordable housing invested by the government.

We have adopted the improved gypsum inner partition wall board.

It is very simple to hang it directly.

At present, in view of the development of precast buildings in our country, how to solve the precast building system? We have encountered the bottleneck problem in our development.

There are many precast component factories in the country.

What’s the problem now? Today, I want to focus on the precast construction.

Precast laminated plates have to be used.

After the laminated slab, it is 13 cm.

This wall board is different from the original wall board.

The 25% concept is to build 100 buildings.

This set of technical system is introduced from abroad.

To the 30th floor, it is equivalent to 90 cm concrete, so the cost is very high.

For the first floor, 3 cm concrete is nothing.

The last one is the decoration technical system, the whole decoration, the integrated kitchen and the integrated toilet, which are now very mature.

The guest’s speech received a warm response.

After talking about the technical system, let’s see how to achieve 50 points, meet the qualification, and then construct the evaluation standard.

The second is the inner wall, which we call the inner partition wall.

When using groove connection, we can either add a seal to solve the problem of sound insulation and cracking.

After we apply the technology, the green one must be used, and the yellow one is optional.

Coal gangue began to be popularized and applied more than 20 years ago.

Now it has been used up and can’t be found..

We all know that foreign buildings are mainly small villas, that is, two floors and three floors, so it is very applicable to them.

Put the thermal insulation plate in the reinforced grid frame and pour on both sides.

Today, this platform launched part of the speech of researcher sun zenggui, former president of Shandong construction and Development Research Institute, for the readers.

It is difficult to ensure the safety of this large board.

We must take out 25 buildings to build precast buildings, so the market is very huge.

Fixing Socket Waved End Nail Plate

At present, more than 25% of social investment projects will reach more than 40% by 2025, which is the time to obtain land, We must promise how many precast buildings to build.

Now it is mainly sintered porous brick.

More than 300 people from 200 units attended the conference, and more than 20 mainstream media reported on the scene.

Let’s review.

One is the problem of thick pouring belt, 30 cm post pouring belt must be left between the two, pipeline installation and so on.

They must be built horizontally to reach 20 points, so they are slightly better than internal and external wall panels.

In this way, the cost is relatively low.

Just choose two here, which completes the national standard of precast buildings.

1 Engineering Co., Ltd.

The conference was co sponsored by the National Institute of building materials industry technology information, the national building materials industry technology supervision and research center and the industrial technology basic public service platform of the Ministry of industry and information technology, and undertaken by China Power Construction Group Shandong Electric Power Construction No.

The development of precast buildings is supported by strong policies.

To vigorously develop precast buildings, the state has issued a series of policies.

How to solve it, we have studied the technical system suitable for the development of precast buildings.

The normal floor slab is generally 10 cm now.

Our load-bearing exterior wall should have two plates, one is in line with the thermal insulation formwork, and the other is the steel wire grid frame, which is poured together with the concrete, which is the quality problem of external wall thermal insulation hollowing, cracking, falling off and fire.

There are a lot of solid waste utilization related to construction.

At the same time, the conference also held the Establishment Ceremony of the “solid waste treatment (industrial application) technology research center” to build a “five in one” comprehensive service platform for industry, University, research and application of scientific and technological innovation, achievement promotion and application, standard formulation, inspection and testing, and talent training, so that more excellent innovative achievements can “blossom” on the platform.

What is mandatory is to be qualified.

Because when the stairs are cast-in-situ, the utilization of formwork is very high, and the reinforcement is very complex.

Second, the evaluation standard of precast buildings has been issued by the state and all provinces.

Now it is mainly divided into four levels.

After that, the green one is 43 points and the yellow one is 3 + 5.

Let’s talk about the prospect analysis of high value-added utilization of solid waste.

I think this is one, Here, according to different structural forms and different functional requirements, the technical combination is different.

In this way, they also have to be used when they are applied, but there are also many problems.
