New construction technology for modern buildings?

Building construction technology responds to the development and promotion of modern virtual mindfulness technology, resulting in virtual building construction technology. The traditional engineering project management organization mode, changes in the international environment and modern information and communication technology guide the emergence of virtual building construction technology. In the traditional engineering project management organization, it presents a kind of "pyramid" type organization, and the problems presented by this kind of organizational structure are mainly reflected in the following: the status of the project construction process of all parties involved in the project is unequal; all parties involved in the project only care about their own interests, thus ignoring the overall goal of the project; there are a large number of management interfaces and process interfaces, and the amount of coordination in the project construction process is large. Coordination in the project construction process; organizational structure of many levels, making the project control more difficult; only command and control, lack of coordination and cooperation atmosphere; slow decision-making process, the phenomenon of serious information silos; information transfer shortages, overloading, distortion, distortion and delay and so on. The following is the main content of the modern building construction new technology introduction brought by Zhongda Consulting for reference.

In terms of changes in the international environment, with the globalization of the world economy, large-scale construction enterprises have also expanded their business scope, is developing towards the world, which leads to more stimulating competition, and today's project management model and tools are increasingly unable to meet today's development needs, seeking a new type of project management model is necessary. In terms of modern information and communication technology, with the rapid development of information and communication technology, people's way of life and work has been affected to a certain extent, but also affects the mode of engineering project management. With the wide application of information and communication technology, it makes the system and mechanism of the construction industry change.

Large-scale engineering projects because of the involvement of the world, so the implementation of the project and mobilization of the inconvenience, making the increase in investment, construction progress is slow, construction quality is reduced, but in the full use of information and communication technology can be very good after the close integration of the projects, more convenient for communication and exchange. It is these external and internal factors and promote the impact of the virtual construction of this new project management model appeared, and will have a significant impact on the entire construction industry and project management level.

The overall planning of the construction project, the institutional design of the building, the allocation of construction organizations, construction products and quality analysis and so on can use virtual construction technology. Can well analyze and predict the problems encountered in the construction, pre-construction preventive measures can also be well dealt with, can be a good amount to solve the construction of the construction of man-made and environmental contingencies, can be scientifically project costs, data control, accurate construction technology, complete the construction unit in the decision-making system optimization and control, overall improve the competitiveness of the industry. The use of virtual building construction technology can establish a perfect model of the actual construction and construction effect, through the simulation of these models to imitate the building construction, the construction of building construction may occur in the prediction and analysis of the situation. Virtual building construction technology is used in a wide range of science and technology, there is a cross-section of this technology, the main processing tool for the computer application software, through the computer application software to analyze and process the building construction. Virtual building construction technology in the application of the process can be very good for the construction of building projects to improve the construction progress, so that the financial and material resources and a variety of building materials can be quickly mobilized and distributed, to a certain extent, to improve the safety of building construction.

High-performance concrete construction technology

High-performance concrete is a new type of concrete, is the use of high technology to significantly improve the performance of the usual concrete on the basis of the use of modern concrete technology production of concrete. The main index of high-performance concrete is durability, but according to different passages can be divided into workability, practicality, strength, volume stability and economy and so on. In order to achieve the above indicators, the concrete configuration process is carried out using a low water-to-cement ratio, based on the addition of a sufficient number of admixtures and high-efficiency admixtures, and the use of high-quality raw materials for production. Easy to pour, pounding, non-segregation, can maintain its own high strength, high toughness and volumetric stability for a long time, and its service life can be maintained for a long time in harsh environments. High-performance concrete is evolved from high-strength concrete, however, it also includes high-efficiency concrete. High-strength concrete is formed by vibro-pressurized molding, after reducing the water-cement ratio, strong vibro-pressurized molding, which can well reduce the porosity, but this kind of concrete is not suitable for on-site construction, so it has not been very widely promoted. In the subsequent is through the mixing of efficient water reducing agent configuration of high efficiency concrete, the emergence of this stage is guided by the emergence of efficient water reducing agent. The last use of mineral additives configuration of high-performance concrete is in the 1980s, the emergence of mineral additives and efficient water reducing agent can be a good combination, *** with the achievement of high-performance concrete. High-performance concrete because of low water consumption, good fluidity, high resistance to segregation, so it has a good filler, with good self-compacting; high-performance concrete has a high modulus of elasticity, low shrinkage and creep, low temperature deformation, so there is a high degree of volumetric stability; high-performance concrete has a great compressive strength, has been used in construction projects; water-cement ratio is low, so the heat of hydration is correspondingly reduced; High-performance concrete has high densification and impermeability, so there is a high resistance to chemical corrosion; high-performance concrete mixed with organic fibers, at high temperatures organic fibers can be melted and volatilized, through a certain reaction to improve the high temperature resistance of high-performance concrete. High-performance concrete work performance is very good, has a good durability, in the cost of high-strength concrete with the same level has a certain gap, per cubic meter of high-performance concrete can directly save thirty-two to sixty dollars or so. High-performance concrete can also save the material cost, about every cubic meter can save the material cost can reach about 40 yuan. Therefore, high-performance concrete has a certain economy, with the increasing use, can be used in modern building construction with good.

Three, new materials driven by green energy-saving technology

With the beginning of the pursuit of land can live differently, with the development of science and technology and the improvement of people's living standards, people in the choice of buildings more the pursuit of warm and comfortable. Environmental health of the living environment, so some architects in the structure of the building design will be based on the green environmental protection as the basis for the design. In the construction process after the completion of the design, the part that plays a leading role is the new building materials, but the new building materials in the price will be different from the traditional building materials, so in the project cost management needs to be careful when choosing the new building materials, reasonable selection of new building materials and reasonable use of new building materials. Nowadays, the continuous emergence of green energy-saving materials, green environmental protection materials and intelligent materials drives the development of construction projects in the direction of green environmental protection, energy saving and intelligence. New building materials have a high resource utilization rate, and most of them have high performance but are relatively low in weight, which can promote the development of construction engineering. In terms of energy saving, the promotion of new building energy-saving technologies presents a cyclic structure, which is manifested as follows: the research of new building energy-saving technologies leads to the evaluation of new building energy-saving technologies, the evaluation is used to select new building energy-saving technologies, and the selection of new technologies is used to promote new building energy-saving technologies after the selection of new technologies; the promotion is followed by the application of new building energy-saving technologies, and the application encourages the users to evaluate and provide feedback on new building energy-saving technologies, and these evaluations provide feedback to the users. After the application, users are encouraged to evaluate and feedback on the new building energy-saving technologies, and these evaluations and feedbacks can influence the research on the new building energy-saving technologies, so that in the continuous cycle, the new building energy-saving technologies that are most suitable for the public can be selected.

In today's world, there have been many types of robots involved in the actual construction of the building to go, these robots in the tunnel development, steel welding, painting inside the building, part of the structure of the building lifting and so on have been widely used. China's construction robots because of the late start, most of the construction robots are still in the primary stage, mainly in the construction of internal painting and a few steel welding, and the number of use is relatively small, in addition to the corresponding backwardness of the technology, and the large number of laborers in our country is also inseparable.

2 ecological biomimetic technology ecological biomimetic technology is the new direction of development of the corresponding technical field, nature is superior, so everything in nature has its own unique characteristics, so we can simulate the existence of a variety of creatures in the natural world, simulation, after the selection of a favorable part of the application. In the construction project, the reasonable use of ecological bionic technology can reduce the pollution caused by building construction in some aspects, so that the construction environment can be civilized in the process of building construction; the application of ecological bionic technology can also make the building to meet the requirements of the coordination of the natural environment; can be very good to improve the indoor living environment of the residents to ensure that the green environmental protection, to reduce the pollution in the process of construction to protect the building itself and the surrounding environment, and to create a new environment. The building itself and the surrounding environment to create a harmonious construction operation.

3 marine technology where we live although it becomes the earth, the earth's water area missing accounted for seventy-one percent of the total surface area of the earth, with the continuous development of the world's population, the per capita land is also decreasing, and the utilization rate of land resources is also getting lower and lower, in the face of these problems, people turn their attention to the sea, began to embark on the development of marine resources. Various marine industrial bases and living habitats will also appear more widely in the ocean, showing a denser distribution. With the continuous development of marine resources, marine cities are able to appear in the seabed as human living environments. Through the development of the space of the ocean and the continuous construction of marine architectural and engineering facilities, the scope of the development of the marine space can be the surface of the sea, the middle of the sea and the bottom of the seabed, and it can also be the sea and the seashore, and so on. In addition to the residential area, numerous recreational facilities can be developed, because the composition of the sea and the earth is different, and the fun brought is also different; in addition to the recreational facilities can also be developed transportation facilities, the submarine technology is widely used in undersea transportation; it can also be developed numerous storage facilities and military bases and so on. Marine construction facilities is a very development potential of the subject, very according to the nature of the ocean research and development of construction technology suitable for the operation of the sea, the development of the ocean to lay a good foundation.
