[Action]

The scrap frame base of the present invention is such that the longitudinal reinforcing member integrally formed on the inner bearing portion of the ceramic porcelain plate is fitted to the vertical reinforcing bar of the opposing reinforcing net, and the ceramic porcelain plate is broken into the reinforcing bar net and the joint or potato joint is jointed. It is a very strong one in which concrete or mortar is placed and filled in the inside of a scrap frame mounted by an appropriate stacking method. According to the method of constructing a waste formwork foundation of the present invention, it is possible to efficiently and effectively remove formwork materials without taking steps such as dismantling and removal of formwork after concrete hardening, mortar finishing of the surface of cast concrete as in the conventional case. Can be used economically to build the desired foundation.

【Example】

The illustrated embodiment will be described in detail below. a is, for example, a horizontal rectangular ceramic porcelain plate having a height of 150 mm and a width of 300 mm, which is composed of an inner proof portion 1 and an outer decorative portion 2, and the inner proof portion 1 is provided with vertical stripes at an outer surface of about 150 mm. The fitting parts 3, 3 are integrally molded. The inner proof portion 1 and the outer decorative portion 2 are formed in a state in which the former is biased upward and the latter is biased downward along one diagonal line of the ceramic porcelain plate a. part 2, with is located below the upper end face 1 ₁ of the inner strength portion 1 a top end surface 2 ₁ a downward inclined surface, a bottom surface 2 ₂ protrudes from the lower end surface 1 ₂ of the inner strength portion 1 downward, second, the outer decorative portion at the left end surface 2 ₃ are made to protrude left outward of the left end surface 1 ₃ of the inner strength portion 1 of 2, the right end face 2 of the right end surface 1 ₄ of the inner strength portion 1 outside the decorative part 2 It is projected to the right outside of ₄ . Reference numeral b denotes a reinforcing bar net, which is a plurality of vertical bars 4 and horizontal bars 5 assembled by welding or the like so as to form a large number of sections having a required size, for example, a height of 300 mm and a width of 150 mm. The construction of the scrap frame foundation to be obtained is carried out as follows. A predetermined foundation main bar 6 is arranged and supported on the base 7, and the base 7
, The reinforcing bar nets b and b are placed opposite to each other with the main reinforcing bar 6 positioned between them, and the width-fixing bar 8 is hung between the required vertical bars 4 and 4 at an appropriate height, and the reinforcing bar nets b on both sides are Holds b firmly. Then, while fitting the ceramic porcelain plate a to the outer surface of the reinforcing bar nets b and b and the vertical bar fitting portions 3 and 3 to the vertical bars 4 and 4,
For example, a desired jointing method such as a broken joint or a potato joint shown in FIG. 4 is adopted for mounting. In this case, the inorganic adhesive 9 is applied to the upper end face 1 ₁ of the inner strength portion 1 of the lower ceramic ceramic plate a, it made to match the lower end surface 1 ₂ of the inner strength portion 1 of the upper ceramic ceramic plate a upper stage The ceramic ceramic plates a are stacked. Further, the vertical streak fitting portions 3, 3 of the ceramic porcelain plate a on which the horizontal streak 5 is to be located are notched 10 to the extent necessary to allow the horizontal streak 5 to pass through. Ceramic porcelain plate a where the width stop bar 8 is located
As for, the corresponding portions of the inner proof portion 1 and the vertical streak fitting portion 3 are cut out 11 in advance. By the above, since the scrap frame c made by mounting a large number of ceramic porcelain plates a on the rebar net b is established and formed on the base 7, after that, the concrete concrete or the mortar d is poured into the scrap frame c. Set and fill. As a result, the scrap frame c has a large number of ceramic porcelain plates a on the rebar nets b, b that are arranged opposite to each other with the basic main bar 6 positioned therebetween.
The vertical streak fitting portion 3 is fitted to the vertical streak 4 to be mounted, and the width stop streak 8 is provided at an appropriate height of the required vertical streak 4.
The hanging, moreover, it was applied an inorganic adhesive 9 between the lower end surface 1 ₂ of the upper end face 1 ₁ and the upper ceramic ceramic plate of the lower ceramic ceramic plate a, concrete or mortar into the interior of the捨型frame c It is possible to construct the desired scrap frame foundation in which d is poured and filled. In addition, when the vertical bar fitting portion 3 of the ceramic porcelain plate a is insufficiently fitted to the vertical bar 4 of the reinforcing bar net b due to a finishing error or a damage notch, etc., the vertical bar 4 is secured to the vertical bar 4 in order to secure it. FIG. 8 shows an example in which both sides of the wound wire-shaped presser 12 are inserted into the longitudinal pores 13 penetrating the inner force-bearing portion 1.

EFFECTS OF THE INVENTION As is clear from the above description, the scrap frame base of the present invention according to claims 1 to 4 is a reinforcing bar in which a vertical reinforcing member fitting portion integrally formed with the inner strength portion of a ceramic porcelain plate is provided in opposition. An extremely strong structure in which concrete or mortar is placed and filled into the inside of a scrap frame that is fitted to the longitudinal bars of the net and the ceramic porcelain plate is torn on the reinforcing bar net in an appropriate stacking method such as joints or potato joints. Is. Further, according to the method for constructing a scrap frame foundation of the present invention according to claims 5 to 7, it is not necessary to take each step such as dismantling and removing the mold after hardening of concrete and finishing mortar on the surface of the cast concrete as in the conventional case. In addition, by efficiently and efficiently using the formwork materials as a part of the foundation, the desired foundation can be constructed economically, and it is possible to sufficiently cope with the recent shortage of formwork carpenters and depletion of wood resources.
