If it hits, it will be weathered and not weather resistant, and the synthetic resin of the support body will repeatedly contract and expand due to cold and hot weather conditions, causing the edge between the concrete wall and the support to break, and the support body will be damaged. When the separator shrinks, a gap is created between the concrete wall and the support body, which causes rainwater to enter the concrete wall and cause the separator to rust, and the rust to come out onto the surface of the concrete wall. It was hot.

ａはセパレーター１０に一体的に嵌着する。 Next, its effect will be explained. After fitting the center hole of the support a into the end of the separator 10 from the other side and inserting the support a, the edge of the locking plate 9 of the support a comes into contact with the stopper 12 of the separator 10. When the support a is strongly pressed inward, the edge of the locking plate 9 is bent inward by the elasticity and the radial cuts 8, and the center hole of the locking plate 9 passes through the stopper 12 of the separator 10, and then the above-mentioned The mouth edge is restored by elasticity, and as shown in FIG. The support a is integrally fitted to the separator 10.

When the separator 10 is closed, the seat plate 6 of the support A is supported by hitting the stopper 12 of the separator 10, and the weir plate A is sandwiched and supported by the main body 1 of the support A and the tightening bolt 14 via the separator 10. After that, vertical flaps B are placed on the outer surface of the weir plate A.
on the outside, fit the tightening bolt 14 into the gap between the horizontal strips C and C, arrange the horizontal strips C and C, fit the washer 18 onto the screw 17 of the tightening bolt 14, and tighten the nut 1.
9 is screwed in, the main body 1 with the seat plate 6 of the support a and the washer 18 tighten and fix the weir plate A, the vertical and horizontal flaps B, C, and C together, and the weir plates A on both sides
The formwork is constructed by maintaining a predetermined spacing.

の１側外面を平らになしてその表面を仕上げる。 After the wall 21 is created by pouring concrete into the cavity formed by the weir plate A, the nuts 19, washers 18, horizontal strips C, C, vertical strips B, and tightening bolts 14 are sequentially installed. , remove the weir plate A and dismantle the formwork. Next, when the protruding tip of the separator 10 is repeatedly bent up and down, left and right, etc. by the first side recess 3 of the support a, the tip is broken off from the groove 13 and removed. Fill the recess 3 with mortar or plug it, and then close the main body 1.
Finish the surface by flattening the outer surface of one side.

１図乃至第６図における同一部分を示す。 Another embodiment of the present invention shown in FIGS. 7 to 10 is one in which the seat plate 6 and the locking plate 9 in the above embodiment are integrated. Alternatively, it is a cylindrical seat plate body made of synthetic resin or the like, and the seat plate 6' is located inside one end of the cylindrical body 23.
and an annular locking plate 9' is integrally formed inside the other end thereof, and the locking plate 9' is provided with a radial cut 8'. Therefore, the seat plate body 22 is placed on the stepped portion 4 of the main body 1.
The seat plate body 22 is buried and fixed in the recess 5 on the other side to form a support a'. Other symbols indicate the same parts in FIGS. 1 to 6.

的に堅牢に形成される。 The present invention consists of a weir plate support for a separator for concrete construction as described above, and even if the main body of the support is mortar, a seat plate made of metal, synthetic resin, etc. is placed in the middle part of the main body, and a seat plate made of metal, synthetic resin, etc. is placed on the other side. Because each locking plate made of metal, synthetic resin, etc. is installed, the mortar of the main body is hard to break due to the support of these seat plates and locking plates, and the support is strong and strong by preventing damage. is formed.

運搬、収納、作業上極めて便利である。 Furthermore, when the center hole of the support tool is fitted to the end of the separator from the other side and the support tool is pushed in, the locking plate of the support tool is actuated by elasticity and radial cuts, and the stopper of the separator engages the seat of the support tool. The support is fitted between the plate and the locking plate, and is integrally fitted to the separator. Therefore, the support can be easily and quickly attached to the separator with a single touch, and since the support will not fall off the separator, the separator with the support can be handled with confidence, making transportation, storage, and work easier. Extremely convenient.

とができて折り易い。 In addition, when the formwork is tightened and assembled, the seat plate made of metal, synthetic resin, etc. of the support comes into contact with the stopper of the separator, and the support is locked by the seat plate, while one of the mortar main bodies of the support Since the weir plate touches the side plane and the weir plate is supported by the main body, it is possible to prevent damage to the supports and the weir plate when assembling the formwork, and to ensure that the formwork is always assembled accurately and steadily. Since the main body and the weir plate are in surface contact, when concrete is poured, the concrete does not enter the recess on one side of the support, and the recess is kept as a space, so it is difficult to place the concrete after the formwork is dismantled. When the protruding end portion of the separator is broken off, the end portion can be bent significantly, making it easy to fold.

表面が風化されるおそれもない。 Moreover, since the main body of the support is made of mortar and its outer peripheral surface is cone-shaped with a small diameter on one side, the main body is of the same quality as the concrete wall and blends well with it and is integrated with it, and its anchoring effect is large and there is no risk of it slipping out. In addition, it adheres well to the concrete wall throughout the year and is retained, leaving no gaps between them, so rainwater can penetrate into the concrete wall, causing the separator to rust, and the rust to come out on the surface of the concrete wall. There is no risk that the exposed surface of the support body will be weathered.

の効果がある。 On the other hand, when filling mortar into the recess on one side of the main body of the support to close the recess after breaking off the protruding end of the separator, since the main body is mortar, the mortar packed into the recess will fit well into the main body. The installation of the filled mortar is ensured, and the center hole of the seat plate in the middle part of the main body of the support is just large enough for the screw at the end of the separator to pass through, so the seat plate and the separator are The stopper can be formed small and can be manufactured easily and inexpensively.
