Japanese Patent Laid-Open No. 10-60910

  However, the above publication has a problem that the base metal to be laid on the ground surface must be selected from two or more kinds of metal fittings that are long or short. In addition, there was a problem that there was no concept or composition of changing the thickness of the flat foundation to large or small.

In the present invention, a horizontally long base metal fitting is provided with a fitting portion of an outer mold on one end in the longitudinal direction, and spaced apart at three places on the other side in the longitudinal direction of the base metal fitting, such as the outer side , the middle and the inner side. Protrusion brackets are provided with a support bracket, and the support brackets are cylindrical and are formed in several lengths, and either the outer, middle or inner support bracket is selected to be either long or short. And insert and attach to the upper end of the support bracket by selecting one from several types of hanging metal fittings, each of which includes an attachment portion and a fitting portion of the inner mold, and the depth of the fitting portion is reduced. By selecting and fitting one of several types of inner molds that are long and short to the fitting part of the hanging metal fitting, the interval between the outer mold form and the inner mold form can be increased and decreased, By increasing and decreasing the height of the opening of each, large and small kinds of concrete flat foundation and vertical foundation each Making it possible to pouring at a thickness thin, it was so as to solve the problem.

  In the present invention, it is possible to make the interval between the inner and outer molds widen up and down in several stages by laying with one kind of base bracket, and to make the vertical foundation width thicker and thinner in multiple stages. This produces an effect that it can be easily placed. In addition, the height of the opening under the inner mold can be easily increased and decreased, so that the upper and lower thicknesses of the flat foundation can be changed and placed in multiple stages. Since there is only one type of base metal fitting, there is an effect that it is possible to remarkably reduce the burden of storing the metal fitting for constructing the simple foundation and transporting it to the site. There is an effect that it is easy to install the base metal fitting and to erect the inner and outer molds. By bolting the column metal fittings, there is an effect that it stands upright and does not incline at all.

  According to the present invention, a fitting portion is provided on one side of one type of horizontally long base metal fitting so that the outer frame is fitted upright, and a bolt hole for erecting the column metal fitting is placed on the other side of the base metal fitting at intervals. A plurality of mounting brackets are attached to the upper ends of the support brackets, and the support brackets are attached in parallel to the outer mold frames that are fitted upright and are fitted upright. Select one of a plurality of bolt holes provided on the bracket and make it stand upright by bolting, and fit the inner mold frame on the fitting part of the hanging metal fitting to be attached to the upper end of the column bracket and make it stand upright parallel to the outer mold frame The width between the inner and outer molds is changed to a wide and narrow width by changing the bolting position of the column bracket, and the height of the opening under the inner mold is raised and lowered, so that the flat foundation and vertical foundation made of ready-mixed concrete It is possible to place each of them with large and small thicknesses and thicknesses. In the bracket of the basic strokes 設用.

  The horizontally long base metal fitting 1 is formed of a single type, and is provided with a fitting portion 2 for fitting the outer mold frame a formed by folding or the like upright on one side end in the longitudinal direction. Bolt holes 3a, 3b, 3c for bolting up the column metal fittings 4 at three places, etc., spaced inside, are provided on the horizontal ground A that has been compacted to construct a foundation as shown in FIG. The base metal fittings 1 are cross-laid at regular intervals along the construction line, and the lower end of the base metal fittings 1 is fitted on the outer fitting portions 2 of the base metal fittings 1 so that the outer frame a is upright. Reference numeral 1a denotes a V-groove for alignment, and reference numerals 1b and 1b denote blind holes such as nails N for fixing upright.

  Cylindrical support brackets 4 are formed of two types of long and short lengths, and bolts 5 are provided downward at the center under each bottom plate 4a by welding or caulking, etc. The bolt 5 is selected from one of the bolt holes 3a, 3b, 3c provided in each base metal 1, and the bolt 5 is fixed and fixed upright. The support bracket 4 is fixed in an upright state by tightening the bolts 5, and does not particularly spread and tilt with the outer mold frame. Two kinds of hanging metal fittings 6 having a depth of the fitting portion 6a are formed at the upper end of the support metal fitting 4, and one of them is selected and a rectangular tube shaped attachment portion 6b is attached and fixed. b is fitted to the fitting portion 6a to stand upright. The upper ends of the inner and outer molds a and b are horizontally aligned, and the bridge member 7 is placed and fixed, and the separator 9 is clamped between the through holes 8a and 8b provided in the middle. Since the column metal fitting 4 does not need to be aligned with the horizontally long base metal fitting 1 due to the cylindrical shape, the bolt 5 can be sufficiently tightened and fixed. Further, the attaching portion 6 b of the hanging metal fitting 6 is easily fixed by the inner middle portion of the four sides of the rectangular tube coming into contact with the four points on the outer periphery of the support metal fitting 4. Moreover, since the support bracket 4 can be rotated by the cylindrical shape of the hanging bracket 6, the fitting of the inner mold frame b can be easily advanced.

  Thus, when the bolt 5 is fixed upright by using the outer bolt hole 3a provided in the base metal fitting 1 at the position where the bolt 5 is fixed, the width W between the outer mold frame a and the inner mold frame b is maximized. The width and thickness of the vertical foundation B to be laid out and placed in concrete are set to the maximum thickness. When the column metal fitting 4 is fixed upright with the bolt 5 in the inner bolt hole 3c, the width W is narrowed to minimize the width thickness. In this way, by selecting one from the outer, inner and inner bolt holes, the vertical foundation B can be driven with a thickness such as three steps. Note that the vertical height of the vertical foundation is a separated surface below the pressing grooves 7a, 7b, and 7c of the bridge member 7. Select one of the two types of support brackets 4 to be held upright with bolts 5 and select one of the two types to increase or decrease the depth of the fitting portion 6a of the hanging bracket 6, and select one of the four types to increase or decrease the longitudinal length. By selecting one of the inner molds b, the vertical height of the opening C between the lower end of the inner mold b and the ground A can be raised and lowered, and the vertical thickness of the flat foundation D to be placed is increased or decreased. It can be changed in four stages. In short, according to the design dimensions of a simple foundation for placing concrete (for example, any combination of 135 mm, 150 mm, 180 mm width of the vertical foundation and 150 mm, 180 mm, 200 mm, 220 mm, etc.) Select one each from the vertical brackets 4, the inner frame b, and the hanging brackets 6, and select the bolt holes 3 to make the column brackets 4 fastened with bolts 5 to make the space between the inner and outer molds wider. In addition, the height of the opening C below the inner mold frame b is raised and lowered to adjust the thickness of each of the openings, and the placement is performed. By increasing the number of bolt holes in the base metal fitting 1 and changing the length of the support metal fittings 4, the hanging metal fittings 6, and the inner mold frame b, it is possible to place various combinations of widths and thicknesses. Become.

  As described above, the inner and outer molds a and b are vertically installed including bolts and installed in parallel. Then, as shown in FIG. 3, the ready-mixed concrete is poured into the inner and outer molds a and b. A vertical foundation B having a vertical height (about 80 to 90% of the inner and outer molds) is placed, and a flat foundation D integrally connected to the vertical foundation B is formed on the lower end of the inner mold b. It is cast. The flat punching foundation D can be driven in a uniform thickness as a whole by forming a clear base gauge at the lower end of the inner mold b. Since the column metal fittings 4 are fixed upright by bolting, the inner mold frame b does not expand or incline due to the input pressure of the ready-mixed concrete at all. After the concrete is solidified, the bolts 9a of the bridge member 7 and the separator 9 are removed, and the inner and outer molds a and b are removed. The base metal fitting 1 and the post metal fitting 4 are embedded, and the inner and outer mold frames a and b can be reused.

  As shown in FIG. 6, the horizontally long base metal fitting 11 is provided with a fitting portion 12 of the outer mold frame a formed by folding on one side in the longitudinal direction, and the interval between the outer side, the middle and the inner side on the other side is set. The pillar metal piece 14 is formed of one type in which the upright portions 13a, 13b, and 13c of the column metal fittings 14 are provided at three places, and the column metal fittings 14 formed in a cylindrical shape with a cross-sectional angle C are leg pieces 14a and 14b protruding from the lower ends. In the upper half of the back surface of the support bracket 14, a latch hole 14 c for latching the latch 15 as an attachment portion of the inner frame b is provided in four stages, such as upper and lower. The support bracket 14 has the leg pieces 4a, 4b to be inserted upright by selecting one of the insertion portions 13a, 13b, 13c of the base bracket 1, and the hanging bracket 15 selects one of the retaining holes 14c. Thus, the latching claw 15a is latched and the inner mold b is fitted to stand upright.

  By selecting one of the upright portions 13a, 13b, and 13c of the base metal fitting 1 so that the column metal fitting 14 is upright, the width between the outer mold frame a and the inner mold frame b is increased or decreased, that is, the thickness of the vertical foundation B, that is, the width The thickness is reduced, and the opening C between the lower end of the inner mold frame b and the ground A is formed by raising and lowering the position of the latching hole 14c for latching the latch 15 with one kind of support bracket 14. This is the same as the previous example except that the thickness of the flat foundation D to be cast can be changed in four levels in the vertical direction.

  In the present invention, the width of the vertical foundation and the thickness of the flat foundation are made several stages by laying one type of base metal fittings on the ground surface, and by selecting pillar metal fittings, hanging metal fittings and inner molds with different vertical lengths. It can be widely used for constructing a simple foundation that can be cast thick and thin.
