Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home supply system, and more particularly, to a home supply system having a logistics server which allows a communication terminal of a user such as a person who wishes to acquire a house or a client to access in an Internet environment. It is about the system.

[0002]

2. Description of the Related Art In general, the process of designing and constructing a house includes:
A designer, a builder (a construction company or a construction company) and a service provider such as a financial institution contact the customer or the client, that is, the user individually, and proceed in a form of providing business or service. Coordinating between these service providers and overall control of the design and construction process. Also, the construction company
Information exchange with designers and financial institutions, ordering of materials to material manufacturers, quality control and delivery date management, construction management of site works, and reports to regulatory agencies, etc., and report necessary report items to the owner.

With the rapid spread of information communication networks such as the Internet, real estate sales and housing construction orders have been made on the Internet, thereby realizing a home sales system for promoting sales of homes and the like. According to this type of home sales system, home buyers and the like can relatively easily obtain various types of information from homepages on the Internet. For this reason, this type of home sales system will greatly contribute to revitalizing the distribution of existing or ready-made homes such as used homes and built-for-sale homes.

[0004]

However, in order to design and construct a new house according to an individual custom design, it is necessary to design, estimate, finance, procure materials as described above.
It is necessary to go through each process such as on-site construction and quality control. In such a process, the owner himself manages each process as a whole, or the whole management is entrusted collectively to a home sales company etc. Method must be adopted.

[0005] For example, when the owner himself manages instructions or information transmission to a designer, a builder, a financial institution, or the like, usually, a large amount of time is required for communication and communication between concerned parties due to lack of specialized knowledge. In addition to the necessity, unclear information may be mixed, and it is practically extremely difficult to perform the entire design and construction process well.

On the other hand, when all management is outsourced to a home sales company or a real estate sales company, it is difficult to ensure transparency throughout the entire process from material procurement to quality management, and at the same time, from design and design supervision to construction management. Since the entire quality control process is under the control of the home sales company, etc., the request of the owner is not sufficiently reflected in the construction, or the information on the construction site is not sufficiently transmitted to the owner, and the information is provided to the owner. There is a concern about the adverse effects such as shortage. In addition, when all the work is outsourced to a home sales company, restrictions on the material acquisition and distribution routes are likely to occur, which not only increases the uncertainty of the material price, but also relies on special imported materials. It is difficult to construct a damaged house.

The inventor of the present invention has conducted research on brick houses adapted to the circumstances unique to Japan for many years. As a result, the dry brick construction method (DUP method (Distribute
d Unbond Pre-stress Method), but when such a special construction method is spread in Japan, imported bricks of good quality and appropriate quantity suitable for dry brick construction method should be installed at each housing construction site at the appropriate time. Need to supply. However, considering the site scale of each housing construction site,
Determining the required number and quality of bricks at each site or small construction company and ordering from the brick production area, or importing the appropriate quantity of bricks according to the construction period at the site, is technically expensive. In practice, there is a great deal of difficulty in practice. Further, even if each construction site or small-scale construction shop can purchase a large amount of bricks at a time, it is extremely difficult in practice to store a large amount of bricks for a long period of time.

On the other hand, a system in which a trading company or an import agency imports a large amount of foreign bricks and transports the bricks to various construction sites in Japan, like the conventional supply system of imported construction materials, is applied to the dry brick method. In such a case, it is necessary to adopt a method of storing a large amount of bricks imported in a lump in a domestic warehouse or the like, and transporting the bricks appropriately to each construction site according to the order. However, in this case, not only the cost of procurement and import, but also the cost of domestic storage and domestic transportation will be added to the product price, so from the original purpose of spreading inexpensive dry brick houses to the country. With deviating results.

The present invention has been made in view of the above problems, and has as its object to perform all processes such as planning, design, construction, material procurement, fund procurement, design supervision, construction management, quality inspection, and the like. By centrally managing and building a housing supply system that allows users to easily obtain construction and design information, the burden on the owner is reduced, the transparency of the housing construction work is ensured, and the inventory of materials is reduced. An object of the present invention is to enable material distribution with no material and high degree of freedom in material selection.

The present invention also provides foreign bricks suitable for use in the dry brick method at low cost, and at the appropriate quantity and at the appropriate time to the construction site, thereby realizing a dry brick house in a realistic manner.
