Abstract

(57) [Summary] [Purpose] To obtain a mold for a mortar pad that is extremely inexpensive to manufacture and that is extremely easy to store and transport. [Structure] A mold for a basic mortar pad, in which a mold body is formed of cardboard with a resin sheet adhered thereto so as to be foldable. Further, a fixed weight margin is provided on the lower edge portion of the mold body.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cardboard formwork, and more particularly to a formwork used to construct a liner-holding motor pad used for equipment installation.

[0002]

[Prior Art]

 Generally, for equipment installation, in order to obtain equipment installation accuracy, a steel plate liner is set on the bottom surface of the equipment and the thickness of the liner is adjusted to set the height and levelness of the equipment. .. In order to set the liner to the desired height, a metal pad is made on the foundation and the liner is set on it. In recent years, there has been a method of using a non-contracting agent grout for a mortar pad and pouring it into the inside of a mold, and a method of pouring the grout into the mold and then removing the mold after curing has been adopted.

Conventionally, a wooden frame or a steel plate has been used as the frame for pad molding by this type of pouring method. As shown in FIG. 3, for example, a wooden formwork 1 is manufactured, installed on the surface of a foundation 2, and filled with mortar 3 inside, and a leveling bolt 4 raised from the foundation 2 is used. It is filled up to the height of the liner 5 to be held.

[0004]

[Problems to be solved by the device]

 However, the molds are generally manufactured locally because the mold internal capacity is large, which is not only difficult to manufacture, but also the capacity is large after use, so handling is difficult. It became difficult and hindered transportation. Also, this type of formwork was expensive.

The present invention solves the above-mentioned conventional problems of large capacity made of wood or steel plate and high cost, can be manufactured at very low cost, and can be stored and transported extremely easily. It is an object of the present invention to provide a cardboard formwork.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a cardboard mold according to the present invention is a mold for a basic mortar pad, in which the mold body is made of cardboard with a resin sheet attached, and is foldable. The lower edge of the main body has a fixed weight allowance.

[0007]

[Action]

 According to the above configuration, the mold body is formed by the thick plate having the resin sheet attached to the surface thereof, and the adhesion to the mold can be effectively prevented when the mortar is filled. Then, a weight can be placed on the weight margin of the lower edge to hold the mold in place. Therefore, the mortar pad can be constructed in the shape formed by the cardboard formwork. Such a formwork can be folded so that it is not bulky when not in use, making it extremely easy to transport and store.

[0008]

【Example】

 Hereinafter, specific examples of the cardboard frame according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is an assembled perspective view and a perspective view showing a folded state of a cardboard frame according to an embodiment. As shown in the figure, the mold 10 of the embodiment has a mold body 14 formed in a rectangular cross section by a side plate made of cardboard 12, and has openings 15 formed at the top and bottom. A resin sheet such as a vinyl sheet 16 is adhered to the inner and outer surfaces of the mold body 14 made of the cardboard 12, so that the cardboard 12 is not directly contacted with the mortar to be filled. There is. In addition, at the lower edge of each side plate of the mold body 14, in the assembled state, a folding margin is formed that is folded back to support the mold body 14 and a weight allowance is formed so that a weight can be placed thereon. 18 is integrally provided.

The mold 10 as described above is erected on the foundation surface so as to surround the attachment part of the liner, and the folded state is held by the folded edge 18 at the lower edge. Then, a weight (not shown) is placed on the folded side 18 to support it and the inside is filled with mortar, whereby a mortar pad having a shape determined by the mold 10 can be constructed.

Then, after use, as shown in FIG. 1 (2), by folding it into a flat plate state, it can be easily stored and transported. Therefore, even when constructing a mortar pad with a large capacity, the cardboard formwork 10 used for this is a flat form for storage and transportation, but by expanding it, it becomes a formwork with a capacity according to the specifications. , The handling will be very good.

[0012]

[Effect of the device]

 As described above, according to the cardboard frame of the present invention, it is a frame for a basic mortar pad, in which the frame body is made of cardboard with a resin sheet attached, and is foldable. The lower edge of the main body has a fixed weight allowance, which makes it easy to price, mass-produces, and folds, which saves space for storage and transportation. ..
