Precast bay windows, precast stairs, integral sanitary ware, precast construction training base, the components produced by the factory are hoisted on site, connected and fixed by sleeve grouting, and then cast-in-situ to form an integral house.

It is mainly composed of tripod, step board, protective mesh and skirting board.

Wang Tao, party secretary and general manager of the green investment company of China Construction Third Bureau, introduced the positive exploration made by China Construction Third Bureau in the field of precast buildings.

The external protection system of the assembled standard floor of the hoisting external rack project adopts the external rack system, and each building is equipped with two floors for turnover.

Zhang Hong, deputy secretary of the Party group and deputy director of Hubei Provincial Department of housing and urban rural development, pointed out that Jingmen Beijing long garden community project has made a good demonstration in terms of general contracting (EPC) management of precast construction projects and quality and safety control of precast construction projects.

Fabricated solid model area cast solid model area cast building exterior wall adopts full concrete structure.

Phase II has 8 buildings and 15 units.

Cast in situ reinforced concrete structure is adopted for the first floor underground and 1-2 floors above the ground, and precast structure is adopted for the third-18 floors above the ground.

VR experience VR experience facilities are equipped with 14 experience contents for common injuries in the construction industry such as falling from height, object strike, electric shock, mechanical injury and collapse, so as to simulate the whole process of safety accidents with simulated scenes, so that workers can truly feel the effects of construction engineering safety accidents such as falling, vibration and shaking, Let workers “safely” experience the “unsafe” accident process and improve their awareness of self-protection.

Combined with the plastering free process of cast structure, the common quality problems such as hollowing and cracking of traditional plastering are effectively avoided.

Zhang Yuxuan, deputy director of the Jingmen Municipal Commission of housing and urban rural development, exchanged experiences on quality and safety management of precast buildings in Jingmen from three aspects: system construction, quality assurance, and mechanism innovation.

Project introduction: phase II of Beijing longhuayuan community is the first precast house return project in Western Hubei, with a planned total construction area of about 145700 square meters and 1076 houses can be provided.

In the production of precast wallboard components, the embedded parts of water and electricity pipelines and railings are embedded in advance to avoid secondary slotting.

The precast exterior wall is standardized in the factory, the accuracy error is controlled at millimeter level, and the surface is flat and smooth.

The Third Engineering Bureau of China Construction Corporation dares to be the first in the world and always strive for the first place..

The external walls, internal walls, laminated plates, laminated beams, stairs, balconies and air conditioning panels of the assembled shear wall structure system are precast in the factory and assembled on site.

Comprehensive electricity experience: comprehensive electricity experience, simulate human electric shock reaction, and improve the prevention awareness of on-site construction personnel.

Jingmen is one of the first batch of precast building demonstration cities in China and the only city selected in Hubei Province.

Zhao Jun, member of the Standing Committee of Jingmen Municipal Party committee, said in his speech that he would take this meeting as an opportunity to actively explore new methods, models and ways of quality and safety management of precast construction projects, so as to promote the development of precast buildings in Jingmen to a new level.

The use of tower crane for disassembly and installation eliminates the external scaffold system of traditional cast-in-situ construction of steel pipe, and greatly saves the use of engineering steel pipe.

Zhang Hong, deputy secretary of the Party group and deputy director of Hubei Provincial Department of housing and urban rural development, ye Bing, head of the provincial general station of quality and safety, Zhao Jun, member of the Standing Committee of Jingmen Municipal Party committee, Du zuopang, chairman of Jingmen urban control group, Zhang Yuxuan, deputy director of Jingmen Municipal Commission of housing and urban rural development, Wei Desheng, deputy general manager of China Construction Third Bureau, Wang Tao, Secretary of the Party committee and general manager of green investment company of China Construction Third Bureau, representatives of Hubei provincial and municipal housing and Urban Rural Development Commission and quality and safety system More than 500 people including representatives of industry enterprises attended the observation meeting.

Observe the highlights of the site and display the components in the display area.

He said that he would further accelerate the layout of precast factories, further strengthen industrial linkage, further enrich precast business units, and promote the development of precast construction business to a new level with higher positioning, greater efforts and more pragmatic measures.

He put forward three opinions on the development of precast construction business in the whole province: first, actively respond and vigorously promote precast construction; Second, pay close attention to management to ensure the quality of precast buildings; Third, strengthen measures to strictly prevent production safety accidents.

On November 21, Hubei lvtou Community Construction Safety Management Bureau held an on-site meeting for the second phase of the project in Jingmen, Hubei Province.

The precast components include precast exterior wall, precast staircase and precast balcony, with an assembly rate of 53%.

As a mode of expanding safety education and training, the safety experience hall in the safety experience area simulates different working environments, so that trainees can personally experience and perceive the safety risks in the construction environment, improve safety awareness, understand safety precautions and improve safety skills.

As the first assembly demonstration project in Jingmen City, the phase II project of Beijing longhuayuan community has played a leading role in the development of assembly buildings in Jingmen City and even Hubei Province.
