Description

[Detailed description of the invention] (Field of industrial application) The present invention is a decorative panel for concrete formwork, which has tiles, etc. attached to the surface and connecting reinforcing bars attached to the back via anchor reinforcing bars, and general This item relates to an auxiliary tool that is used by being attached to the connecting reinforcing bars on the back side of the decorative panel in order to connect the end of the separator to the connecting reinforcing bars on the back of the decorative panel when constructing a concrete casting space with concrete formwork. It is.

(Prior Art) As shown in FIG. 1, a decorative panel 4 for concrete formwork is known, which has a decorative tile 1 attached to its surface and a connecting reinforcing bar 3 attached to its back side via an anchor reinforcing bar 2. It is being This decorative panel 4 is used as an outer concrete form board when constructing the outer wall of a building, etc., and as shown in the figure, it is used as an inner concrete form 5 to form a concrete pouring space 6. In this case, the outer decorative panel 4 and the inner concrete formwork 5 must be connected by a separator 7 at a certain distance.

In this case, the separator 7 must be connected to the connecting reinforcing bars 3 in the decorative panel 4, but the conventional auxiliary tools used for this purpose are:
Recessed portions for fitting reinforcing bars are provided from one side of the opposite side plate portions of the U-shaped bent plate material, and a side edge of the recessed portion on the side of the connecting plate portion that connects the opposite side plate portions,
A claw part was formed to prevent the reinforcing bar from falling out, which was fitted into the recessed part.

(Problem to be solved by the invention) In the conventional auxiliary tool as described above, the claws for preventing the reinforcing bars from falling off cannot be easily elastically deformed, so the amount of protrusion of the claws must be set to a sufficient amount. Unless it is made smaller, the auxiliary tool cannot be easily fitted to the reinforcing bar. Therefore, the claws are less likely to catch on the reinforcing bars, and a sufficient retaining effect cannot be obtained. Furthermore, even if the claws have the effect of preventing the reinforcing bars from coming off, they cannot sufficiently press and fix the reinforcing bars, so the auxiliary tool fitted to the reinforcing bars moves in the longitudinal direction of the reinforcing bars, and the reinforcing bars do not come off easily. The auxiliary tool rotates around the separator, making it difficult to connect the separator to the auxiliary tool.

(Means for Solving the Problems) In order to solve the above-mentioned problems of the conventional art, the present invention aims to form recesses for fitting reinforcing bars from one side of the opposite side plate parts of the plate material bent in a U shape. are provided, respectively, and cut-and-raised tongue pieces projecting diagonally outward are formed on the connecting plate side of the recessed portion that connects the opposite side plate portions, and the tips of these tongue pieces are fitted into the recessed portion. The present invention proposes an auxiliary tool for supporting a decorative panel for concrete formwork, which is formed with a recess that fits and presses the joined reinforcing bars, and further includes a separator connection part on the connecting plate part.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

As shown in FIG. 2, the auxiliary tool 8 of the present invention is provided with recesses 11 for fitting reinforcing bars from one side 10 of opposite side plate parts 9a and 9b of the plate material bent into a U shape, respectively.
Cut and raised tongue pieces 13a and 13b are formed on the side of the connecting plate part 12 that connects the opposite side plate parts 9a and 9b of this recessed part 11, respectively, and project diagonally outward.
A recess 1 is provided at the tip of both tongue pieces 13a, 13b to fit and press a reinforcing bar (the connecting reinforcing bar 3 of the decorative panel 4 shown in FIG. 1) fitted in the recess 11.
4, and the connecting plate portion 12 is further provided with a screw hole 15 as a separator connection portion.

The pair of left and right tongue pieces 13a and 13b are formed with inclined side edges 16 that widen the entrance of the recessed part 11. Moreover, the recesses 14 of the tongue pieces 13a, 13b
A reinforcing bar positioning recess 17 is formed at the inner end of the recess 11 so as to face the recess 17 .

The auxiliary tool 8 configured as described above is shown in FIG.
As shown in FIGS. 3 and 4, the connecting reinforcing bars 3 of the decorative panel 4 are fitted into the recessed portions 11 from the lateral side. At this time, a pair of tongue pieces 13a are inclined diagonally outward,
13b is expanded outwardly against elasticity due to the push between the inclined side edge 16 and the reinforcing bar 3, allowing the reinforcing bar 3 to move relatively into the recessed part 11. When the reinforcing bar 3 reaches the inner end of the recess 11 and fits into the reinforcing bar positioning recess 17, the pair of tongue pieces 1
3a and 13b also return to a slightly elastic state, and the recess 14 at the tip thereof fits and presses the reinforcing bar 3, thereby fixing the auxiliary tool 8 to the reinforcing bar 3.

The auxiliary tool 8 fitted and fixed to the connecting reinforcing bars 3 of the decorative panel 4 has a screw end portion 7a of the separator 7.
is screwed into the screw hole 17 to connect the separator 7. The other end of the separator 7 is connected to the concrete formwork 5 by a conventionally known method.

(Operations and Effects of the Invention) According to the support aid for a decorative panel for concrete formwork of the present invention, which can be implemented and used as described above, reinforcing bars for anchors are attached to the back of the decorative panel that also serves as a concrete formwork. The separator can be easily connected to the connecting reinforcing bars that are attached through the reinforcing bars.In particular, cut-and-raised tongues that project diagonally outward are formed on the sides of the recesses for fitting the reinforcing bars, and these tongues Since a recess is formed at the tip of the tongue to fit and press the reinforcing bar fitted into the recess, the elastic displacement of the recess at the tip of the tongue to press against the reinforcing bar fitted into the recess can be facilitated. At the same time, the amount of elastic displacement can be increased, and even though it is easy to fit and attach the auxiliary tool to the reinforcing bars, it is possible to firmly position and fix the auxiliary tool to the fitted reinforcing bars. be. Therefore, the operation of connecting the separator to the auxiliary tool can be easily performed.

Moreover, according to the configuration of the present invention, no separate parts are required for pressing and fixing the reinforcing bars, and the structure can be simple and inexpensive.
