Description

Description: TECHNICAL FIELD [0001] The present invention relates to a separator mounting structure used when arranging a formwork.

[Background Art] The construction of concrete walls and columns is generally performed as follows. First, reinforcing bars for reinforcement are arranged in a vertical direction and a horizontal direction at predetermined positions, a formwork is assembled so as to surround the reinforcing bars, and the outside of the formwork is pressed by a fixed frame (flap material). Then, concrete is poured into the formwork and solidified, and then the fixed formwork and the formwork are removed to obtain concrete walls and columns whose insides are reinforced with reinforcing steel. The above fixed frames are connected to each other by rods called separators so that the fixed frames do not expand due to the concrete pressure when the concrete is poured into the fixed frames. That is, holes are provided in the mold frame and the fixed frame at positions opposite to each other, the separator is penetrated into the mold frame through the holes, and each end of the separator is fixed to the outer surface of the fixed frame.

[Problem to be Solved by the Invention] The work of penetrating the separator into the formwork is performed at a position where there is no reinforcing bar. Therefore, it is designed so that the holes of the formwork and the fixing frame that determine the penetration position of the separator and the reinforcing bar are displaced. However, in practice, a slight error may occur in the arrangement position of the reinforcing bars, and in that case, the separator may hit the reinforcing bars, and the separator cannot be penetrated. In that case, the work of changing the arrangement of the reinforcing bars must be performed, which is very time-consuming. In particular, since the Great Hanshin Earthquake, the arrangement density of reinforcing bars has become high, and the above problem has become serious. The present invention has been made in view of the above circumstances, and an object of the present invention is to facilitate the work of arranging a separator in a formwork, thereby improving work efficiency.

[Means for Solving the Problems] In order to achieve the above object, according to the present invention, a first plate body mounted on an outer surface of a mold, and the mold is fixed by being provided on the mold. A second plate body mounted on the outer surface of the fixed frame, and a connecting body that connects each of the plate bodies in a direction perpendicular to their surface direction, and the form frame and the fixed frame of each of the plate bodies; Each of the mounting surfaces is formed with a protruding circular fitting mounting portion whose center is coaxial with each other, and further, the separator is located at a position facing each other of the plate members and at a position deviating from the circular center position. Each of the insertion holes is provided, and the separator insertion hole is displaceable by being rotated in a state where each of the fitting attachment portions is fitted in the circular mounting opening of the mold frame and the fixed frame. Provided is a jig for mounting a separator, wherein the jig is mounted on a jig. By using the separator mounting jig of the above configuration at the mounting position, the mold frame, the separator insertion hole of the fixed frame for fixing it, can be displaced together, thereby adjusting the mounting position of the separator and separating the separator to a position without rebar. Can be inserted and arranged. In particular, since the fitting mounting portion protruding from the mounting surface side of each plate body is circular, and each of the separator insertion holes is provided at a position deviated from the center position of the circle, the separator mounting By rotating each plate body with the jig attached, displacement adjustment of the separator hole can be easily performed.

FIG. 1 is a front view of a jig for mounting a separator according to the present invention.
2 is a rear view, FIG. 3 is a plan view, FIG. 4 is a side view, FIG. 5 is a sectional view taken along line AA of FIG. 1, and FIG. 6 is a sectional view taken along line BB of FIG.
The jig 1 for attaching a separator is made of metal, and includes a pair of circular plates 2 and 3 arranged so as to face each other, and a connecting member 4 that connects the plates 2 and 3 to each other.
A circular annular projection 7 is provided integrally on the mounting surface of the front plate 2, and a circular projection 8 is provided integrally on the mounting surface of the rear plate 3. At positions facing each other, separator insertion holes 5 and 6 are provided at positions eccentric from the center. The connecting body 4 has a configuration in which L-shaped steels are combined. Next, a mounting configuration of the separator mounting jig 1 will be described with reference to a sectional view in use of FIG. 10 is a mold, 11 is the mold 10
It is a fixed frame arranged outside. The circular annular protrusion 7 on the front plate 2 mounting surface is in the opening 13 of the fixed frame 11, and the circular protrusion 8 on the rear plate 3 mounting surface is in the opening 15 of the face plate 14 of the mold 10. The jig 1 for attaching the separator is fitted by being fitted from the outside. The jig 1 for attaching the separator is similarly attached to the form frame 10 and the fixed frame 11 facing each other across the concrete molding space P. At that time, the separator insertion holes 5 and 6 of the separator mounting jig 1 on each side are relatively arranged, and both ends are inserted into the insertion holes 5 and 6 so that the separator 30 is provided so as to penetrate the concrete molding space P. ,And,
Both ends are fixed to the surface of the fixing frame 11 with screws 19. Next, the adjusting function of the separator mounting position of the separator mounting jig 1 will be described. In the jig 1 for mounting the separator, the circular annular projection 7 on the mounting surface of the plate 2 is located within the opening 13 of the fixed frame 11, and the circular projection 8 on the mounting surface of the rear plate 3 is positioned on the face plate 14 of the mold 10. The separator mounting jig 1 can be mounted on the surface of the fixed frame 11 at a desired rotation position. Now, if it was installed in the state shown in FIG.
The separator insertion holes 5 and 6 are located at the lowest position. On the other hand, when the horizontal reinforcing bar 20 in the space within the formwork is located as shown by the dotted line, the reinforcing bar 20 becomes an obstacle, and the separator 30 cannot be inserted and arranged. Then, the jig 1 for mounting the separator is rotated. Then, the separator mounting jig is rotated in the direction of the arrow so that the separator insertion holes 5 and 6 do not face both the horizontal reinforcing bars 20 and the vertical reinforcing bars 21, and displaced to the dotted line position. In this way, the mounting position of the separator 30 can be adjusted so as to avoid the reinforcing bar. As the plates 2 and 3 of the jig 1 for mounting the separator, for example, insertion holes 5 having a diameter of about 50 to 60 mm and a diameter of about 18 mm are used.
In this case, by rotating the jig 1 for mounting the separator, the mounting position of the separator 30 can be adjusted at a distance of up to about 40 mm in the vertical and horizontal directions. Conventionally, insertion holes are fixedly provided in a mold frame and a fixed frame, so if there is a reinforcing bar in that position, the insertion arrangement of the separator cannot be performed.

[Effects of the Invention] According to the present invention, when constructing a concrete wall or column, the work of arranging the separator in the formwork while avoiding the reinforcing bar can be easily performed, thereby improving the work efficiency. Is enhanced.
