DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete formworking apparatus and an embedded concrete used for the same, and more particularly to a concrete formworking apparatus which is suitable for constructing a concrete formwork in an inclined state.

[0002]

2. Description of the Related Art Conventionally, in the case of concrete casting, which is the most basic construction, a separator shaft and a separator shaft are provided between a pair of formwork facing each other at a predetermined interval. Concrete was cast in a state where the spacing between the molds was regulated by interposing embedded capacitors connected to both ends and the molds were fixedly supported. However, when a concrete formwork is installed in an inclined shape and an inclined surface is formed by casting concrete, a movable support fitting is used as described in Japanese Utility Model Publication No. 41-4427, or a taper con- trol is used.
No. 6950, which was used as described in JP-A-6950. Also, the concrete form was removed after the concrete casting and the outside of the separator shaft was cut off, but in order to cope with the inclination of the concrete form very much. In addition to the problem that the construction device tends to be complicated in structure, there remains a problem that post-processing for waterproofing the inside of the embedded concrete after removing the concrete formwork is troublesome.

Therefore, in the present invention, even when the concrete formwork is installed in an inclined manner, it has a simple structure which is easy to cope with as a construction apparatus, and also performs very post-processing for waterproofing after concrete construction. The present invention has been made with an object to provide an easy-to-use concrete formworking apparatus and an embedded concrete used for the apparatus.

[0004]

According to the concrete formworking apparatus of the present invention which can achieve the above object, as described in claim 1, one of the openings on the concrete form side is provided in the embedded concrete. The other side has a tapered hole formed wider than the other opening side, the other opening side is provided with a hemispheric washer, a separator shaft is inserted through the tapered hole and the hole of the hemispheric washer, and the separator shaft is made of concrete. The position can be adjusted within the tapered hole with the hole of the hemispheric washer as a base point in accordance with the degree of inclination of the formwork.

According to the present invention according to claim 1,
The embedded concrete must be inclined according to the state of inclination of the concrete formwork, but the tapered hole formed by the embedded concrete is formed wider on the one opening side closer to the concrete formwork side than on the other opening side. Therefore, by adjusting the position of the separator shaft in the tapered hole with the hole of the hemispheric washer as a base point, the embedded condenser can be easily adjusted to the inclined state.

Further, according to the concrete formwork apparatus of the present invention, a slope ruler member having an inclined surface corresponding to the inclined concrete formwork is embedded between the concrete formwork and the concrete side. Is characterized by being inserted and fixed to the separator shaft on the opposite side, and on the side opposite to the embedded concrete side across the concrete form, the inclination of the concrete form,
The above-mentioned gradient ruler member can easily respond. In particular, if the slope ruler members are prepared in advance corresponding to several inclination angles at which the concrete formwork is selected for construction, the responsiveness becomes better. By combining a plurality of, preferably two, members instead of one slope ruler member, it is possible to cope with various inclination angles.

Further, the concrete formwork apparatus of the present invention is characterized in that, as described in claim 3, a separator shaft which can be cut off after the work is applied at the position of the hemispheric washer is used, and the separator shaft is used. After cutting, the tapered hole remains in the embedded container, so it is possible to finish the waterproofing after removing the concrete formwork simply by inserting a water swellable stopper in this tapered hole. Becomes Further, as for the embedded concrete used in the concrete formwork construction apparatus of the present invention described above, as described in claim 4, the taper hole formed so that one opening side closer to the concrete formwork side is wider than the other opening side. A hemispheric washer is provided on the other opening side while being formed, and it is characterized in that it can be held on the separator shaft in an inclined state according to the degree of inclination of the concrete form, and the concrete mold is provided. When adjusting the position of the separator shaft in the tapered hole of the embedded capacitor in order to make the embedded capacitor correspond to the inclination of the frame, when the embedded shaft hits the narrow opening side due to contact with the separator shaft, it may break. The hemispheric washer can prevent this, and the separator shaft can be cut off at the hemispheric washer position. Hole position of the washer becomes the position adjusting base and ablation origin of separator shaft, hemispherical washer becomes possible to satisfactorily protect the embedded configuration, has helped prevent damage to the embedded configuration.

[0008]

Next, an embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 are cross-sectional views showing a state after concrete casting, and FIG. 3 is a cross-sectional view after removing a concrete formwork, showing a case of construction having a concrete inclined surface. A and A 'in FIG. 1 are concrete forms, in which at least one side of a construction surface for placing concrete is constructed as an inclined surface, and the concrete form A on the side to be constructed as an inclined surface is attached in an inclined manner. Can be In particular, the inclined side is shown enlarged in FIG. Reference numeral 10 denotes an embedded condenser, which is formed of mortar, concrete or synthetic resin, and has a tapered hole 13 formed so that one opening 11 side closer to the concrete formwork side is wider than the other opening 12 side. A hemispheric washer 14 is fitted or fixed to the other narrow opening 12 side.

Reference numeral 20 denotes a separator shaft which is inserted through the tapered hole 13 of the embedding condenser 10 and the hole 15 of the hemispheric washer 14. The separator shaft 20 has a tapered hole corresponding to the inclination of the concrete form A. The position of the embedding concrete 10 is held in the separator shaft 20 along the inclination of the concrete form A by adjusting the position with the hole 15 of the hemispheric washer 14 as a base point.

The separator shaft 20 is provided with the hemispheric washer 1.
A weakened portion formed with a protrusion 21 for preventing withdrawal so as to be positioned at the position of the hole 15 of No. 4 and having a small diameter so that it can be easily cut off from the embedded concrete 10 at the position of the hemispheric washer 14 after casting concrete. 22 is formed. Next, on the opposite side of the embedded concrete 10 across the inclined concrete form A, an inclined surface 31 corresponding to the inclination of the concrete form A is provided.
The slope ruler member 30 having the following structure is inserted through the separator shaft 20 and fixed with a nut 32, so that a configuration capable of immediately responding to the inclination of the concrete form A is adopted.

In addition, one of the inclined concrete form A
The other concrete form A 'facing the concrete form at an interval of concrete placement is set in an inclined state similarly to the concrete form A on the one side, and as shown in FIG. The vertical state is set as described above. In the case of the vertical state, the slope ruler member 30 is unnecessary outside the other concrete form A '.
As described above, after setting the concrete formworking apparatus to a state in which concrete can be poured, concrete C is poured. After the concrete is cast, the nut 31 of the separator shaft 20 is attached to the inclined concrete form A 'side. After removing the slope ruler member 30, the concrete form A is removed and dismantled, and the separator shaft 20 is weakened at the position of the hemispheric washer 14 as a weak portion 22.
Is cut from the inside of the embedding condenser 10 and the tapered hole 1 of the embedding condenser 10 is completely vacated by the resection.

On the other hand, the concrete form A 'which is not inclined is also dismantled and post-processed in the same manner except that the concrete form A' does not have the slope ruler member 30. The stopper 40 may be formed by mixing a water-swellable material, or may be formed by coating a water-swellable coating only on the surface or a necessary portion. As a result, a waterproof function is generated in the stopper insertion portion. As for the slope ruler member 30 used in the concrete formwork described above, not only one piece is used, but also a plurality of pieces, preferably about two pieces are combined so that the tilt angle can be changed, so that the tilt angle of the concrete formwork A is different. In this case, the angle adjustment on the side of the slope ruler member 30 becomes diversified, so that it becomes easy to carry out.
