These units are combined and joined to one another to form blocks and the blocks are connected to constitute a steel framed basement, whereby sufficient strength is provided without using reinforcing shape steels. As a result, fabrication and construction can be simplified, achieving thereby low cost.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a basement, which maximizes the characteristics of steel materials, reduces the amount of steel materials used and the amount of work involved in manufacturing, improves quality, and stabilizes the quality of construction. This is related to the technology that builds by improving the workability and significantly shortening the construction period.

[0002]

2. Description of the Related Art In the construction of a conventional steel basement, a ceiling steel, a wall panel, and a floor panel are reinforced with flat steel by a shaped steel, and the corner connection portions are pin-bonded to receive external force. The pressure board and external force are transmitted.

[0003]

However, in the method of constructing such a steel frame basement, the reinforcing steel of the outer panel,
The amount of steel material for beams and columns becomes large, and the amount of work required during production is large. Even if the units are unitized, there are many structural conditions such as the positions of columns and beam joints, external panels and columns, and the method of joining beams, which is complicated. Will turn into. The joint part of the external panel is also a horizontal joint between ceiling panel and wall panel, horizontal joint between wall panel and floor panel, and there are many joints such as vertical joints between ceiling panels, between wall panels, and between floor panels, so there is a risk of flooding. Also, at the construction site, after the foundation or pressure plate is made of reinforced concrete and sufficient strength is generated, the basement is assembled and the amount of assembly work is large, requiring a long construction period. The drainage of water will become indispensable.

The present invention has been made in view of the above problems, and an object thereof is to eliminate the problems of the above-described conventional method for constructing a basement.

[0005]

In order to achieve the above object, the present invention provides a corrugated steel sheet (8, 8) having a large cross-sectional performance such as a geometrical moment of inertia and an allowable compressive stress on the exterior, ceiling, wall, and floor.
The use of 9) made the reinforcing steel unnecessary.

[0006] In addition, by making the joint between the ceiling and the wall of the corner portion of the corrugated steel plate (8) and the wall and the floor rigidly, the external ceiling,
Since the wall and floor are integrated into a rigid frame structure to resist external force, beams and columns are no longer needed, so there is no column, so no foundation or pressure board is required.

Due to the above reasons, the amount of steel used and the amount of work during manufacturing can be reduced, and the unitization is also possible with the unit with an end opening (1), the unit with an intermediate opening (2), the intermediate unit (3), and the end. Since it is easy to manufacture the partial unit (4) by making it into a block and the number of joints can be minimized, it is possible to reduce the risk of flooding.

[0008] Further, the work amount at the construction site does not require a foundation or pressure plate, and the basement assembly is reduced by the connection of each block unit and the water stoppage treatment of the joint portion, which greatly shortens the construction period. As a result, there is a high possibility that there will be no need for work such as mountain retaining and drainage of seepage water.

[0009]

As described above, the corrugated steel sheet is used on the external ceiling, wall, and floor by flowing in the direction perpendicular to the girder direction of each block unit, and the large moment of inertia of area and the allowable maximum moment of area, which are the characteristics of the corrugated steel sheet, are used. By utilizing compressive stress and rigidly connecting the four corners of the ceiling-wall, wall-floor mating part, the external ceiling-wall-floor becomes an integral rigid frame structure that resists external forces, It is possible to reduce the maximum moment by creating an end moment at the end, and the side pressure that the end opening unit and the end unit receive on the wall on the end side goes directly to the corrugated steel plates on the ceiling, wall and floor of each unit. This makes it possible to reduce resistance by using continuous ribs, which eliminates the need for beams and columns, reduces the amount of material used, and reduces the amount of work during manufacturing.

In the construction work, excavation is performed to level the bottom of the basement, and the basement can be installed without a foundation or pressure plate, and the unit can be assembled on the end of the wife side. Units with end openings (1) that have openings in the ceiling in the ceiling (1) Units with intermediate openings that have openings in the ceiling (2) Intermediate units that have some openings in the middle (3) Wife side Since the end unit (4) used for the end of the is divided into blocks with the girder direction sliced, it is possible to tighten the connection flanges with bolts and from the inside of the basement. No extra work space in between, small amount of excavated soil is required, it is safe and economical, and the assembly place is small factory, if it is assembled in the factory, transported and installed,
It can be selected according to safety, economic efficiency, workability, and whether or not there is a construction period, such as assembling on the ground if the assembly conditions are set at the construction site and at the installation site if it is a large basement.

[0011]

Embodiments of the present invention will now be described with reference to the drawings. In FIG. 1, the basement has a doorway opening in the ceiling, which is also used as a block unit, at the end on the end side. A unit (1) with an end opening, a unit with an intermediate opening (2) that has an opening for a doorway in the ceiling, which is used in a state of being sandwiched in the middle portion, and an intermediate unit (3) that is used in a state of being sandwiched in the middle portion, At the end of the wife side, it is manufactured as an end unit (4) which is used. The details of the end unit will be explained with reference to FIGS. The steel plate (8) is made to flow and the four corners of the ceiling, wall and floor are rigidly joined (5) to form an integral rigid frame structure. Use and weld all around the receiving flange (15) Re continuous rib (7) prevents concentrators external force out with end reinforcement angle (16) Continuous Konaribu (1
0) and the end unit, and the connection of the units, the corrugated steel plate (8) is connected to the connection flange (6) welded all around the edge of the corrugated steel plate by sandwiching the water stop band and tightening the bolt. The outer joints other than the above are all welded all around and there is no gap of water infiltration. ) Is processed and transmitted to each unit, and after the above unit is manufactured, external and internal rust-proof treatment is applied to prevent corrosion. Insert one end unit or unit with end opening, attach a water stop to the connection flange, and bolt the connection flange of the intermediate unit or unit with intermediate opening to connect. The basement unit is assembled by finally connecting the end units or units with end openings in the same way, and the backfilling is performed so that earth pressure is evenly applied to the basement wall surface. Complete.

[0012]

As described above, the present invention eliminates the need for a reinforcing steel by using corrugated steel sheets having a large cross-sectional performance such as the second moment of area and the allowable compressive stress on the external ceiling, wall and floor. By rigidly connecting the ceiling and wall at the corners of the corrugated steel plate and the wall and floor at the corners, the external ceiling, wall and floor become an integral rigid frame structure that resists external forces, so beams and columns are also unnecessary. Since there is no pillar, no foundation or pressure board is required.

For the above reasons, it is possible to reduce the amount of steel used and the amount of work during manufacturing, and to unitize the unit, the unit with an end opening, the unit with an intermediate opening, the intermediate unit, and the end unit go straight in the girder direction. It is easy to make a block in the form of a slice, and the number of joints can be minimized, so the risk of water intrusion can be reduced, and the amount of work at the construction site does not require a foundation or pressure plate, and Assembly of the basement is also reduced by connecting blocks of each unit and stopping water treatment at the joint part, and the construction period can be shortened significantly, so there is a high possibility that there will be no need for mountain retaining or drainage of permeated water. You can build a basement at a cost.
