Description

[Detailed description of the device]

[Industrial applications]

The present invention relates to improvement of a separator in a reinforced concrete building or the like.

[Prior art and its problems]

Generally, as for the concrete temporary frame, as shown in FIG. 7, the wooden temporary frame panels P, P are the separators shown in FIGS. 8 and 9.
In order to support the concrete filled inside by the temporary frame panel P while maintaining a constant distance by C1 and C2, as shown in FIG. 10, a steel auxiliary angle I is bitten on the auxiliary bar F on the outside, The wedge D is inserted and fixed to the one-touch hardware A that engages with the head protruding from the wooden temporary frame panel P of the separator C, or the home tie (registered trademark B1) shown in FIG. 11 is attached to the head of the separator C2. The wedge D is screwed, and the wedge D is inserted and fixed in the metal fitting B2 engaged with the screw. However, in any case, after removing the temporary frame, since the head of the separator is protruding from the concrete surface, it is necessary to cut or bend the protruding member,
It takes time. Therefore, a method has been proposed in which a female screw is provided on at least one end of the separator and a tip drill is screwed onto the female screw. (Actual development number 58-44344). However, such a structure has a drawback that rainwater or the like easily enters the screw holes and easily rusts. Therefore, a cone member (Fig. 5) is interposed so that the screw holes can be filled with some member or material after concrete is placed. Although it has been proposed to fill the hole taken out with concrete, it is difficult to take out the cone member, and the embedding area is large, which causes the appearance to be significantly damaged.

[The purpose of the device]

The present invention has been made paying attention to the fact that a concrete washer is used as a separator washer, and the above drawback can be solved by embedding and fixing the washer together with the separator. Slightly shorter than P interval, female threads on both ends
A central anchor member 11 having 11a, 11a, and a concrete separator washer 13 that is in contact with both ends of the central anchor member 11 and is provided inside the temporary frame panels P, P, and at least one of which is a cement plate It consists of a pair of separate washers 13, 14 and a projecting member 12 having a male screw 12a screwed into the female screw 11a at the tip thereof and capable of inserting the separator washer 13, 14 therein. A separator that also serves as an anchor is characterized in that, when is removed from the central anchor member 11, a concrete separator washer 13 composed of the cement plate is embedded and fixed in a concrete surface.

[Action]

According to the present invention, in the case of a wall of exposed concrete, the concrete separator washer is integrally fixed to the concrete wall. Will be formed. Hereinafter, the present invention will be described in detail based on specific examples shown in the accompanying drawings.

【Example】

FIG. 1 is a partially cutaway perspective view showing the whole anchor / separator according to the present invention, and FIG. 2 is a sectional view thereof. (1) is a separator for reinforced concrete, which has a central anchor member 11 having female screws 11a, 11a at both ends, and a male screw 12a screwed with the female screw 11a at its tip, and a separator washer 13 inserted into the left protruding member. 12, normal washer 14
And a right side protruding member 12 which is inserted therethrough. As shown in FIGS. 3 to 5, the separator washer 13 is
A washer made of a cement plate, when removing the protruding member 12 from the central anchor member 11 after removing the temporary frame,
It is left on the concrete surface. As shown in FIG. 6, the separator (1) holds the wooden temporary frame panels P, P at a constant interval by the separator (1) and supports the concrete filled therein with the temporary frame panel P. A steel auxiliary angle I is bitten on the auxiliary bar F on the outer side thereof, and a deformed wedge (3) is attached to the fixed metal fitting (2) which engages with the head 12b of the protruding member 12 from the wooden temporary frame panel P of the separator (1). Insert and fix, after the concrete has set,
After removing the temporary frame, the protruding member 12 is attached to the central anchor member 11
Remove from. At this time, the recess 12c of the protruding member 12 may be removed by turning it with a spanner. As a result, only the anchor member 11 and the concrete washer 13 remain in the concrete, and the concrete washer 13 is exposed to the outside of the concrete outer wall.
11 is never exposed directly.

[Effect of device]

As is apparent from the above description, according to the present invention, the reinforced concrete separator (1) is provided at both ends with female screws 11 at both ends.
a central anchor member 11 having a and 11a, and a male screw 12a screwed to the female screw 11a at the tip, and a separator washer
Since the protruding member is made removable by forming the protruding member by inserting the pair of protruding members 12 into which 13 is inserted, it is not necessary to cut or bend the protruding member after removing the temporary frame as in the conventional case. In such a structure, the female screw end face is exposed to the outside, but since it is embedded in the concrete wall surface together with the concrete washer, it is possible to form a beautiful concrete wall surface by injecting concrete into the female screw through the concrete washer. , Enforcement becomes easy.
