【Brief Description】 According to Gao Jian, the steel structure house is to prefabricate the frame of the building according to the size in advance in the factory. After it becomes a "section steel", it is transported to the construction site, and finally assembled mechanically like building blocks. "After the steel beams and the steel frame were transported to the site, they were connected with high-strength bolts, and some parts needed to be welded again. To put it in vernacular, the skeleton of this building is not traditional reinforced concrete, but is composed of section steel."

According to Gao Jian, the steel structure house is to prefabricate the frame of the building according to the size in advance in the factory. After it becomes a "section steel", it is transported to the construction site, and finally assembled mechanically like building blocks. “After the steel beam and the steel frame are transported to the site, they are connected with high-strength bolts, and some parts need to be welded again. In the vernacular, the skeleton of this building is not traditional reinforced concrete, but is composed of section steel. ”

Gao Jian said that after the overall steel structure frame of the residential building is completed, the floor slab is still built by pouring concrete, while the outer retaining wall is built with ordinary hollow bricks.

Morning News (Reporter Guo Jinfeng) The 18-storey building has a "steel skeleton", and building a house is like "building blocks".

This is the first steel structure house just built in Shenyang, and 1008 residents will live here.

Yesterday, the reporter came to the third phase of the workers' new village park at No. 10 Zangong Street, Tiexi District.

Accompanied by engineer Guan Kai, the reporter visited this somewhat mysterious "steel building block castle".

Guan Kai opened the door of a room in Unit 2, Building 17, Phase 3 of Workers New Village, and what appeared to the reporter was a three-bedroom house, two of which were facing south, and the interior was ready for handover. .

“The area of ​​this house is about 82 square meters. ” Guan Kai came to a south-facing bedroom, pointed to a beam above the window and a column on the right side of the window, and said that only the beam and column in this house are steel structures, and the rest of the walls are normal brick-concrete structures .

Guan Kai further explained to the reporter: "It is different from ordinary houses that use reinforced concrete to bear the load. The load-bearing inside is square hollow steel, and the hollow is poured with concrete. ”

The usable area is 5% more than that of ordinary houses

1. The construction speed can be doubled

Referring to the advantages of steel structure housing, Gao Jian, chief engineer of the project construction unit Tiexi Urban Construction Development Co., Ltd., said that the first is that the construction period will be shortened.

Gao Jian said: “Because the steel beams and steel frames are prefabricated in advance, they can be assembled directly on the construction site. Compared with the reinforced concrete construction method of ordinary houses, the construction speed can be doubled. ”

Gao Jian said that with the increase in speed, the requirements for assembly workers have also increased accordingly. The workers responsible for assembling steel beams and steel frames at the construction site are all professional and skilled workers.

For the Northeast region, the speed of construction is inseparable from the temperature. Steel structure housing has also broken through this bottleneck.

“Concrete needs to be poured in ordinary residential buildings. If the temperature is low, the construction work cannot be completed; while the steel structure residential construction is mainly splicing work, which completely gets rid of the limitation of temperature. " said Gao Jian.

2. Can resist a magnitude 6 earthquake

According to Gao Jian, another major advantage of steel-structured houses is that they have excellent seismic performance.

“The flexibility of the brick-concrete structure of ordinary residential buildings is much lower than that of steel-structured buildings. At the time of design, the steel structure house can resist earthquakes of magnitude 7. If it is replaced by the series that people often say, it can resist earthquakes of magnitude 6. ”

At the same time, regarding the fire resistance of steel-structured houses, Gao Jian confidently said: "Before construction, we coated all steel surfaces with fire-resistant materials, and the fire safety of the houses can be fully guaranteed. ”

3. The usable area is larger than that of ordinary residences

In addition to the high safety factor, steel-structured houses also have an advantage that citizens can benefit from, that is, the indoor area is about 5% larger than that of ordinary houses.

When the steel structure house is built, the walls are much thinner than ordinary reinforced concrete houses because the skeleton is made of steel.

“The walls are thinner, but the thermal insulation performance will not be affected. ” Gao Jian said that thin walls will directly make the usable area of ​​the house larger than that of ordinary houses.

“The specific data has not been measured on the spot for the time being, but according to some previous data, the usable area of ​​steel structure residential buildings can be 4%~5% larger than that of ordinary residential buildings. " said Gao Jian.

Answers to the public

The question in my heart

1. When can residents move in?

It is expected that before the Spring Festival, the first batch of residents will be able to live in new houses

At present, the district demolition bureau is checking the relevant information of the demolition residents. After the public announcement, it will enter the allocation stage. It is expected that the first batch of residents will be able to live in new houses before the Spring Festival.

In the spring of next year, the third phase of the workers' new village will start the construction of the park. The sidewalks and curbs are made of high-grade paving materials such as granite, and an international standard plastic floor badminton court will also be built; stone tables and benches will be installed for residents to rest; installation A full set of fitness equipment, green coverage rate of more than 30%. According to "Shenyang Daily"

2. Will there be troubles when decorating?

The interior of the house is made of brick and concrete, which will not affect the decoration

Ms. Zhang, a citizen, said that she did not know much about steel structure houses and wanted to know if there would be any problems in the decoration of steel structure houses?

Gao Jian said that the steel structure of the residential building is limited to the skeleton part of the building, so there will be no problems in the decoration. "The walls in the house, like other ordinary houses, are all brick-concrete structures. For example, smashing walls, drilling holes, installing air conditioners, and similar tasks that require drilling holes in walls can be done normally, and you don't need to worry about this. ”

3. What is the cost of the steel structure house?

The cost per square meter is about 300 yuan higher than that of ordinary houses

Gao Jian said: “Compared with ordinary houses, if the houses are also 18 stories high, the direct construction cost per square meter of steel structure houses is about 300 yuan higher. However, since steel structure houses do not need to use a large amount of building materials such as cement, sand, and water, the advantages in saving building materials and energy are also higher than those of ordinary houses. ”
