Abstract

PROBLEM TO BE SOLVED: To complete concrete placing in foundation work at one time by stably holding a cantilever type garage by joining columns of the cantilever type garage by bolts to a shape steel foundation frame having horizontal level adjusters. SOLUTION: A foundation frame A is constituted in a rectangular shape by H shape steel 2 and 2 and C shape steel 3 and 3, and connecting parts 4 and 4 to join columns 1a and 1a of a cantilever type garage by bolts are arranged so that the center of gravity of the cantilever type garage is positioned on the foundation frame A, and a reinforcing welding wire net 6 is unfolded in the frame. First of all, a hole H in which the foundation frame A is embedded is excavated, and cobble stones (g) are laid, and the foundation frame A is arranged on it, and the columns 1a and 1a of the cantilever type garage are joined to the connecting parts 4 and 4 by bolts, and the cantilever type garage is erected, and a horizontal level of the foundation frame A is adjusted by horizontal level adjusters 5 arranged in the four corners of the foundation frame A, and concrete is placed. Therefore, the cantilever type garage is stably held only by the foundation frame A, and concrete placing can be completed at one time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of foundation work, and more particularly to a method of foundation work for a garage or the like, and more particularly, to a foundation work suitable for an unbalanced upper body such as a cantilevered garage. This is the method.

[0002]

2. Description of the Related Art Conventionally, when foundation work such as a cantilever type garage is performed, a hole is dug in a place where a pillar is to be erected, and a bar is laid. Cast concrete and embed anchor bolts to connect to columns. Cure for 3-4 days. Erect columns and adjust the horizontal level. Assemble the garage body. Concrete is cast in the foundation connection of pillars and in the soil. Cure for 3-4 days. (Refer to Fig. 1). However, this requires the assembler to go to the site twice, once () and second (). Further, since the curing of the concrete is performed twice, it takes 8 to 10 days to construct the concrete.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention is a method of foundation work in which concrete placement can be completed in a single operation.
An object of the present invention is to provide a method of foundation work in which the number of times required for the work is sufficient and the curing time for the concrete is one, so that the number of work days is greatly reduced.

[0004]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a base having a connecting portion with a column such as a cantilevered garage and a horizontal level adjusting device. This is a method of foundation work performed using a frame, and as a connecting portion, even if a cantilevered garage or the like is erected on the foundation frame as described in claim 2, the entire center of gravity is deviated from the foundation frame. In other words, the connecting portion may be arranged at a position where the garage main body can be held upright without embedding the base frame, and the horizontal level adjusting device may be a base frame as described in claim 3. By providing screw holes at the four corners and receiving the tip of the bolt penetrating downward through the screw hole with a plate, turning the bolt forward and reverse to finely move the four corners of the frame up and down and adjust the horizontal level of the base frame Is what you do. As a process sequence, a hole for embedding a foundation frame is dug as described in claim 4, the foundation frame is horizontally installed in the hole by a horizontal level adjustment device, and the main body pillar is connected to the connection portion to form a foundation. This is a method of foundation work in a cantilevered garage or the like, wherein concrete is cast after standing a cantilevered garage or the like on a frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing a cantilever type garage 1 erected by a conventional foundation construction method, where g is a grind, C1 is concrete poured in a first time, a is an anchor bolt, and C2 is a second time. It is concrete poured in.

FIG. 2 is a perspective view showing a standing portion of an upright cantilever garage 1 according to the foundation construction method of the present invention. It is a rectangular frame made of shaped steel members 3, 3. Connection portions 4, 4 are provided on the upper surfaces of the end portions of the left and right H-shaped ropes 2, 2, respectively, and provided at the lower end portions of the pillars 1a, 1a of the cantilever garage. The connection plates 1b and 1b are connected and fixed by bolting. Further, horizontal level adjusting devices 5 are arranged at the four corners of the base frame A, respectively. H is a hole for embedding the base frame A and has a depth of about 300.
mm, and grits g are laid inside. Further, a reinforcing wire mesh 6 is placed in the base frame.

FIG. 3 is a sectional view showing the cantilever type garage 1 erected according to the foundation construction method of the present invention. A grind g is laid on the bottom surface of the hole H, and a foundation frame A is placed thereon. The connecting portion 4 provided on the upper surface of the end of the shape rope 2 and the connection plate 1b attached to the lower end of the pillar 1a are fixed with bolts 7 to fix the cantilever type garage, and the H-shaped rope 2 A screw hole is provided in the short U-shaped steel 5b welded to the base plate, and the adjustment bolt 5a of the horizontal level adjustment device 5 in which the tip of the adjustment bolt 5a penetrating downward is abutted against the ground plate 5c is turned in the normal or reverse direction. The horizontal level is adjusted by slightly moving the frame A up and down. In addition,
Since the size of the base frame A is set so that the center of gravity of the entire garage is located on the base frame, in this state, even if the concrete is not struck, the base is self-supporting.

FIG. 4 is a cross-sectional view showing a state where concrete C3 has been struck after the horizontal level adjustment in FIG. Since the cantilever type garage 1 is self-supporting, the portion of the foundation frame and the portion between the soils can be cast simultaneously.

FIG. 5 is a schematic diagram showing the use of the foundation construction method of the present invention.
It is sectional drawing in the state where the cantilever type garage 1 'of another shape was set up, 1'a is a pillar and 1'c is a sub pillar. Although the cantilever type garage 1 'has four pillars but is located at a position closer to one side, it is preferable to use the foundation construction method of the present invention.

[0010]

According to the present invention, the method of foundation work in a cantilevered garage or the like is a conventional method in which an assembler would have to visit the site twice in two steps. Is completed once, greatly reducing the number of construction days. In addition, since the center of gravity of the garage main body is located on the base frame, the garage is self-supporting without any support, so the whole is stable and the embedding depth is shallower than before. can do.
