段に落ちることになるという欠陥があつた。 Generally, the spacing holders at the bottom end of the formwork for fabric foundation concrete are placed on the top surface of the base concrete, so two outer regulating pieces and two inner regulating pieces are erected at each end of the holder body. However, the top surface of the base concrete is not necessarily flat, and as a result, a gap is formed between the spacing fixture and the bottom surface of the fabric foundation concrete formwork, and the fabric foundation concrete against the outer regulating piece of the spacing fixture is not flat. Point of action (contact point) at the bottom end of the formwork
The defect was that the spacer would move upwards, thus significantly reducing the strength of the spacer.

As shown in Publication No. 23832, the upper part of one of the outer regulating pieces of the spacing holder is bent inward in a dogleg shape to form an elastic locking protrusion in order to lock it to the formwork. The upper part of the other outer regulating piece is bent inward at right angles to prevent the spacing retainer from separating from the fabric foundation concrete formwork, or the outer regulating piece has a transparent locking hole and is attached to the fabric foundation concrete form. There was also a type in which the spacing holder was lifted by locking the lower end of a spring that was hooked to the top of the formwork. However, in the former, there is still a slight gap between the formwork and the spacing holder due to manufacturing and installation errors in the formwork or spacing holder, and in the latter, gaps are difficult to form, but when the structure is multiple There was a problem that manufacturing was difficult and the cost of the product was high.

ンクリートの打設状況の確認窓となる。 Hereinafter, an embodiment embodying the present invention will be explained with reference to Figs. 1 and 2. In the drawings, reference numeral 1 indicates the entire spacing retainer of the present invention, and the central part of the rectangular iron plate is shown along the longitudinal direction. The reinforcing protrusion 2 is formed by extrusion molding upward with a press, and both ends are bent upward to form outer regulating pieces 3, 3, and a position at a constant distance inward from the outer regulating pieces 3, 3 is the reference point. A substantially U-shaped cut is made in the reinforcing protrusion 2 and bent upward to form the inner regulating pieces 4, 4. The distance between the outer regulating pieces 3, 3 and the inner regulating pieces 4, 4 is set as formwork fitting portions 5, 5, and the distance therebetween is made equal to the thickness a of the formworks 6, 6, respectively. Note that the through hole formed after bending and raising the inner regulating pieces 4, 4 becomes a window for checking the concrete placement status when used as an upper spacer.

くぎ孔10が透設されている。 7 can be made of a thin (0.4 to 0.6 mm) strip-shaped iron plate, etc., which is welded to the upper part of the inner surface of the outer regulating pieces 3, 3 at its wide side 7a and provided in a horizontally elongated shape in the width direction of the outer regulating pieces 3. A locking piece having flexibility, the formwork 6,
6. Bend both sides 8 of the locking piece 7 inward in the lateral direction with your fingers, as shown in FIG. The narrow side 7b of the spacer 7, that is, the lower edge thereof, is engaged with the upper edge of the reinforcing rib 9, so that the entire spacing holder 1 can be engaged with the lower surface of the molds 6, 6. In addition,
A nail hole 10 for installing the spacing holder 1 at a predetermined position in the base concrete B is provided near the center of the spacing holder 1.
さて、本考案の間隔保持具は次のようにして使
用される。 Now, the spacer of the present invention is used in the following manner.
すなわち、まずベースコンクリートB上に適当
間隔に本考案の間隔保持具を並べ、その両側の嵌
合部5,5に対し型枠6,6の下端部を嵌合して

部8を第2図二点鎖線のように型枠6,6の補強
リブ9,9の上縁部直上にて内方へ折り曲げて型
枠6,6に間隔保持具1を係止する。 That is, first, the spacing holders of the present invention are arranged at appropriate intervals on the base concrete B, and the lower ends of the formworks 6, 6 are fitted into the fitting parts 5, 5 on both sides. The spacing between the formworks will be kept exactly constant. Thereafter, both sides 8 of the locking piece 7 are bent inward as shown by the two-dot chain line in FIG. Lock the holder 1.
場合によつては、型枠6,6の上部にもこの間
隔保持具1を下向きに使用することが可能であ
る。 Depending on the case, it is also possible to use this spacer 1 downwardly on the upper part of the formworks 6,6.
そして、コンクリートは両型枠6,6間に打設
されるので、下部に使用した間隔保持具1,1は
そのまま埋め殺される消耗品となつて、外側規制
片3,3を含む間隔保持具1,1の両側部が露出
するが、通常土中に埋設されるから何らさしつか
えない。又上部に使用される間隔保持具1は型枠
6,6の取り外し時に一諸に取り外される。 Since the concrete is cast between the formworks 6, 6, the spacing holders 1, 1 used at the bottom become consumable items that are buried as they are, and the spacing holders 1, 1 including the outer regulating pieces 3, 3 become consumables. Both sides of 1 and 1 are exposed, but this is not a problem since they are usually buried in the ground. Further, the spacer 1 used in the upper part is removed all at once when the formworks 6, 6 are removed.
さて、本考案実施例においては、外側規制片

い。 Now, in the embodiment of the present invention, the flexible locking pieces 7, 7 are welded to the inner surfaces of the outer regulating pieces 3, 3 at their wide surfaces 8, 8. It can be bent inward and locked from any part in the middle just above the upper edges of the reinforcing ribs 9, 9 of the formworks 6, 6. Therefore, the unevenness of the upper surface of the base concrete B causes the formworks 6, Even if the installation position is crooked or there is a manufacturing error in the reinforcing ribs 9, 9, the spacer 1 can always be locked in a securely abutting state against the lower surface of the formworks 6, 6. Also,
Even when the reinforcing ribs 9, 9 are locked on the narrow surface 7b of the locking piece 7 and a bending moment is applied to the locking piece, the section modulus on the narrow side 7b of the same width is larger than the section modulus on the wide side 7a. Therefore, deformation is unlikely to occur.

鎖線で示すように内側へ折り曲げて係止する。 Figures 3 to 5 show a second embodiment, in which one of the pair of outer regulating pieces 3, 3' is approximately U-shaped so that it can be hooked to the lower end of the formwork. It is formed into a shape. In this embodiment, the formwork 6
The U-shaped outer regulating piece 3'
After locking, rotate in the direction of the arrow in Fig. 4 so that the lower ends of the forms 6, 6 are fitted into the formwork fitting parts 5, 5 as shown in Fig. 5, and then lock. Both sides 7a of the piece 7 are bent inward as shown by the two-dot chain line in the same figure so as to be above the reinforcing rib 9 and locked.
第6図及び第7図は第三の実施例を示し、両外
側規制片3の外側面にそれぞれ係止片7を幅方向
に設けたものである。 6 and 7 show a third embodiment, in which locking pieces 7 are provided on the outer surfaces of both outer regulating pieces 3, respectively, in the width direction.
第8図及び第9図は第四の実施例を示し、第一
の実施例の両係止片7の一方の側部8のみを内側
へ折り曲げるようにした点において異なつてい
る。 8 and 9 show a fourth embodiment, which differs from the first embodiment in that only one side 8 of both locking pieces 7 is bent inward.
ところで、前記係止片7を一方にのみ設ける場
合には、係止片7を設けた方の内側規制片4を省
略しても良い。すなわち、係止片7があれば内側
規制片4がなくても、同係止片7の先端部をさら

上下方向及び横方向の相対移動を防止することが
できるからである。 By the way, when the locking piece 7 is provided only on one side, the inner regulating piece 4 on which the locking piece 7 is provided may be omitted. That is, if the locking piece 7 is present, even if the inner regulating piece 4 is not present, the tip of the locking piece 7 can be further bent downward to grasp the upper edge of the reinforcing rib 9 of the formwork 6, thereby allowing the formwork to be secured. This is because relative movement of the spacer 6 and the spacer in the vertical and lateral directions can be prevented.
反対に係止片7を一方にのみ設ける場合には、
係止片7を設けない方の内側規制片4を省略する
と、型枠6と間隔保持具との横方向の相対移動が
生じるので、都合が悪い。 On the contrary, when the locking piece 7 is provided only on one side,
If the inner regulating piece 4 on which the locking piece 7 is not provided is omitted, it is inconvenient because a relative movement in the lateral direction between the formwork 6 and the spacer holder will occur.

ることができる効果がある。 In this way, the present invention provides an outer regulating piece by bending both ends of a strip-shaped plate upward, and a locking piece that is fixed in a horizontally elongated manner to the outer or inner surface of at least one of the pair of outer regulating pieces. When the locking piece is laterally protruded from the fixed part and the locking piece is bent laterally inward, the lower edge of the locking piece can lock the upper end of the lower edge of the formwork, making it possible to manufacture and install the formwork. Even if there is an error, the spacer can always be reliably locked in the correct position with respect to the same mold, and the structure can be simplified to reduce the cost of the product.
