[0005]

1 to 3 show an embodiment of a method for constructing a basement according to the present invention. In the drawings, reference numeral 1 indicates a predetermined thickness on an excavated ground surface excavated to a predetermined depth. Concrete foundation (hereinafter referred to as "foundation 1"), 2 are installed on this foundation 1, steel floor panels that make up the floor part of the basement, 3 are erected on the foundation 1, and are the pillars of the basement. The steel columns 4 are bridged over the upper ends of the steel columns 3, and the steel beams that make up the steel frame of the basement with the steel columns 3 are erected around the steel floor panel 2 to form the outer wall of the basement. The constituent steel wall panels, and the reference numeral 6 are provided on the upper end of the foundation 1,
An anchor bolt for fixing the steel column 3 to the foundation 1.

Each of the steel frame columns 3 and the steel frame beams 4 is made of H-section steel or the like. Further, each of the steel floor panel 2 and the steel wall panel 5 is configured by framing a plurality of shaped steels 7 in a rectangular frame shape and welding a steel plate 8 to one side surface thereof.

Further, the steel floor panels 2 are connected to each other and installed on the foundation 1, the steel wall panels 5 are connected to each other, and the steel floor panels 2 and the steel columns 3 or the steel beams 4 are connected to each other. It is installed around the steel floor panel 2 while being fixed.

The anchor bolt 6 continuously penetrates the anchor bolt insertion hole 8a formed in the steel plate 8 of the steel floor panel 5 and the anchor bolt insertion hole 9a of the base plate 9 attached to the lower end of the steel column 3. There is. Further, the steel nut 3 is firmly fixed onto the foundation 1 by screwing the anchor nut 10 into the male screw portion 6a at the tip of the anchor bolt 6.

The anchor bolt through hole 8a formed in the steel plate 8 of the steel floor panel 2 is fitted with a washer 11 after the anchor bolt 6 is inserted, and the washer 11 and the periphery of the anchor bolt through hole 8a are welded. This ensures that it is waterproof.

Further, the level of the steel frame column 3 is adjusted by filling a level adjusting mortar 12 around the anchor bolt 6 to a predetermined height.

With such a structure, the construction method of the basement according to the present invention will be described step by step.

(1) First, the ground is dug down to a predetermined depth, and the foundation 1 is formed on the excavated bottom surface.

In this case, the anchor bolt 6 is projected at a predetermined position before the concrete is poured.

(2) Next, when the concrete of the foundation 1 develops a sufficient strength, leveling mortar 13 is applied on the foundation 1 to a predetermined thickness to adjust the level, and then the steel floor is placed thereon. Install panel 2. In this case, at the protruding portion of the anchor bolt 6, the anchor bolt insertion hole 8a of the steel floor panel 2 is formed.
The anchor bolt 6 is further projected, and a sufficient waterproof treatment is performed by interposing a sealing material (not shown) at the joint between the steel floor panels 5 and 5.

Further, a washer 11 is attached to the anchor bolt 6, and the washer 11 and the anchor bolt through hole 8a.
The periphery of the anchor bolt 6 is also waterproofed by welding the periphery thereof.

(3) Next, the steel column 3 is erected on the protruding portion of the anchor bolt 6, and the anchor bolt 6 is passed through the anchor hole 9a of the anchor plate 9.

Then, the level adjustment mortar 12 is filled in a predetermined thickness around the anchor bolt 6 to level the steel column 3, and when the leveling is completed, the anchor nut 6 is attached to the male screw portion 6a of the anchor bolt 6. The steel pillar 3 is firmly fixed onto the foundation 1 by screwing.

(4) Next, around the steel floor panel 2, while connecting the steel wall panels 5 to each other, the steel floor panel 2
And, it is installed while being fixed to the steel column 3 or the steel beam 4.

In this case, a joint portion between the adjacent steel wall panels 5 and 5 and a joint portion between the steel wall panel 5 and the steel floor panel 2 are joined together by interposing a sealant (not shown). The waterproof treatment of shall be surely performed.

[0020]

According to the present invention, which has the structure described above, it is extremely easy to assemble the steel frame of the basement and assemble the steel floor panel and the steel wall panel by the above steps. There is.

Particularly, when building a steel column, a steel floor panel is installed on a concrete foundation, and anchor bolts protruding from the anchor bolt insertion hole formed in the steel floor panel are provided. To fix the steel column by screwing an anchor nut onto the male thread of the anchor bolt, and by filling the periphery of the anchor bolt with level adjustment mortar to adjust the level of the steel column. The anchor bolt insertion holes formed in the floor panel are completely closed after inserting the anchor bolts for waterproofing, so it is possible to erected steel pillars securely and easily, and to simplify basement construction There is an effect that it can be quickly converted into a structure.
