It seems that the construction deepening design should be done carefully! ▲ The wallboard transported to the floor for installation ▲ The balcony wallboard installed ▲ The node of the anti-seismic column installed ▲ The hook of the hanging electrical pipe line is directly attached to the precast floor without casing or bridge.

It must be completed soon after the main mechanism is hoisted and capped.

Presumably, the effect must be very good.

▲ Precast members transported to the construction site ▲ The upper row of steel bars of the beam are bound together with the precast members in the factory.

What you know is exactly what you need…..

This project is a 50 story precast super high-rise residential building, which is a column seismic node.

There is no need to worry about the insulation falling off of exterior walls, and it is also easy to update after decades of use.

It can be seen that the sound insulation design is in place.

The hat is brand new, and the inside is also equipped with a disposable health guard, which is very hygienic and considerate! It is not like the black, sweaty and dusty safety helmet often seen on domestic construction sites.

How efficient it is! ▲ A group of five workers cooperate to install the precast beam ▲ The hole for electromechanical threading is reserved on the beam during factory prefabrication ▲ The embedded parts connected with the tower crane are also embedded in the prefabrication factory.

As a microcosm of the development of Japanese precast buildings, you can feel a lot after watching it.

See, eight screw holes of each embedded part are exactly the same.

This precast residence has a total of 50 floors.

The author also saw that each bolt and nut was marked with a diagonal line with a colored pen.

Such industrial production is really impressive! Let us understand the significance of vigorously promoting precast buildings in China! Clean and tidy construction site: just arrived at the construction site meeting room, I saw the safety helmet prepared by the host for the visitors.

When we visited, it had been installed and constructed to the 40th floor.

The interior walls, floor tiles and bathroom decoration have been completed in the factory ▲ The fixing method of the ground pipeline is made by using galvanized shaped supports, The transition block is carefully set at the place where the hose meets the return beam to prevent the deformation caused by gravity from affecting the smoothness in future long-term use.

▲ The formal staircase is cast steel structure, and the construction and installation are two floors faster than the floor structure, so that the construction personnel can pass up and down easily, which saves the temporary passage cost and is very safe.

Colorful lines distinguish different functions ▲ The toilet is also an integrated industrial product.

The following indoor wall installation, mechanical and electrical construction, and decoration construction are connected closely and orderly.

Can you imagine why? ▲ The thermal insulation is made indoors by spraying foam adhesive, which is much easier to construct than the common practice of pasting insulation boards on exterior walls in the north of China.

▲ For the installation of precast columns, the embedded parts for on-site installation and support have been reserved in the factory in advance.

▲ The external wall tiles have been completed in the factory along with the precast components, which is different from the common practice of external wall thermal insulation in China.

The host also prepared gloves and disposable socks for visitors.

At the End Comment Office, you can add the wrong or missing parts of the article, so that the next person who sees it will learn more.

The external wall tiles are directly pasted on the precast concrete components.

Isn’t it amazing? ▲ The node of the precast beam column component is made of on-site post cast concrete ▲ We just walked upstairs by the construction elevator and just saw that the precast beam on the ground car has been lifted up.

▲ Japan is an earthquake prone country, and its seismic technology is very advanced.

▲ The corridor wall concrete sill is embedded with installation holes and connecting iron pieces ▲ The embedded parts required for the wall under the beam are buried in the factory.

After the installation of the floor slab on the site, a layer of floor steel bars will be anchored into the post cast concrete slab.

▲ The drainage riser is wrapped with sound insulation cotton ▲ This is the construction model of the floor slab.
