Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a space holder that holds a space between partitioning molds and the like when forming a cloth foundation.

[0002]

[Prior art]

 In general, when a step for entrances and exits and partition ventilation holes are provided on a cloth foundation for a house, a pair of partition forms are sandwiched between concrete forms that are arranged opposite to each other. Then, in order to fix the partition formwork, the top plate was fixed to the upper joint of the concrete formwork with wedge stoppers or floating prevention metal fittings.

[0003]

[Problems to be solved by the device]

 However, in the above technology, since the top plate of the partitioning formwork is only fixed to the upper joint of the concrete formwork by the wedge stopper and the lifting prevention metal fitting, a large pressure is applied to the lower part of the partitioning formwork. In that case, there was a problem that the partition formwork could be deformed. The present invention has been made to solve the above problems, and its purpose is to prevent the partition form from being deformed even when a large pressure is applied to the bottom of the partition form. The object is to provide a space holder for supporting the frame.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, a plurality of long tubular pipes are provided with through holes at predetermined positions, one of the pipes is inserted into the other, and a fixing pin is passed through the through hole to be polymerized. By adopting this configuration, a structure is adopted in which the pipes are connected and fixed.

[0005]

[Action]

 The operation will be described below based on the configuration of the present invention. First, at the time of forming the cloth foundation, by mounting the top plate on the upper shaft of the pair of facing concrete formwork, the pair of partitioning formwork is installed according to the step or the width of the partition ventilation hole between the concrete formwork. To wear. Then, fix the top plate of the partitioning formwork to the upper joint of the concrete formwork with wedge stoppers or floating prevention metal fittings, and then temporarily install the formwork spacing retainer of the present invention between the partitioning formworks. The partition formwork is supported and fixed by bringing the holding plate into contact with the lower part of the partition formwork. In this way, the partitioning formwork will not be deformed even if a large pressure is applied to the lower part of the partitioning formwork during concrete pouring.

【Example】

 An embodiment of a partitioning mold spacing holder embodying the present invention will be described below with reference to FIGS. 1 and 3 to 8.

The partitioning mold spacing holder 1 of this embodiment is composed of a long rectangular tubular square pipe 2, square pipe 3 and square pipe 4 having the same end faces and different sizes. A support plate 5 is welded and fixed to one ends of the pipe 2 and the square pipe 4. As shown in FIG. 3, the rectangular pipe 2 has a rectangular support plate 5 welded and fixed to the right end thereof. A through hole 7 is provided on the left end side. As shown in FIG. 4, the square pipe 3 has a smaller end surface than the square pipe 2 so that it can be inserted inside the square pipe 2, and four through holes 8a, 8b, 8c are formed at both ends and the central portion. , 8d are provided. The square pipe 3 is engraved with a marking 15 and an instruction line 17a at the center right portion, and a marking 16 and an instruction line 17b at the right end portion. As shown in FIG. 5, the square pipe 4 has a smaller end surface than the square pipe 3 so that it can be inserted inside the square pipe 3, and a supporting plate 5 is welded and fixed to the left end of the square pipe 4. . The square pipe 4 is provided with a through hole 9c at the right end and through holes 9a and 9b at the center right part. Further, the corner pipe 4 has markings 11 and 14, marking lines 18a and 18b at the left end, marking 12 and marking line 18c at the center right part, and marking 13 and marking line 18d at the right end. There is. The square pipe 3 is inserted inside the square pipe 2, and the square pipe 4 is inserted inside the square pipe 3, and the fixing pins 6 are inserted into the overlapping holes to fix the pipes. The fixing pin 6 is formed in a substantially U shape and is loosely inserted into the holes 10a of the projecting pieces 10 provided on the square pipe 2 and the square pipe 3, respectively.

Now, a method of adjusting the length of the partitioning frame interval holder 1 of this embodiment will be described below with reference to FIGS. 6 to 7. The partitioning frame interval holder 1 of this embodiment can be adjusted in length in 5 steps, and as the mark, the square pipe 3 and the square pipe 4 are engraved with the above-mentioned markings and indicator lines. . For example, as shown in FIG. 6, when making the length F, first insert the square pipe 3 into the square pipe 2, align the end face of the square pipe 2 with the indicator line 17a, and then set the square pipe 4 into the square pipe 3. , And the end face of the square pipe 3 is aligned with the indicator line 18b. At this position, the through hole 7, the through hole 8c and the through hole 9b are superposed, and by inserting the fixing pin 6, the square pipe 2, the square pipe 3 and the square pipe 4 are connected and fixed to each other. When making the length A shorter, by keeping the positions of the square pipes 2 and 3 unchanged and aligning the end face of the square pipe 3 with the indicator line 18a of the square pipe 4, the through hole 7, the through hole 8c, and the through hole 8c. 9a polymerizes. On the contrary, when making the length B a little longer, the positions of the square pipe 2 and the square pipe 3 remain the same, and if the end face of the square pipe 3 is aligned with the indicator line 18c of the square pipe 4, the through holes 7 and 8c are formed. The through holes 8a and the through holes 9b are polymerized. When the length is further shifted to C, the positions of the square pipes 2 and 3 are kept as they are, and if the end face of the square pipe 3 is aligned with the indicator line 18d of the square pipe 4, the through hole 7, the through hole 8c, and the through hole are formed. 8a and the through hole 9c are polymerized. In order to obtain the longest length D, as shown in FIG. 7, the end surface of the square pipe 2 is aligned with the indicator line 17b of the square pipe 3, and the end surface of the square pipe 3 is aligned with the indicator line 18d of the square pipe 4. Then, the through hole 7 and the through hole 8d and the through holes 8a and 9c are polymerized.

Next, a manner of use of the spacing member 1 of this embodiment will be described with reference to FIG. First, the pair of partitioning molds 21 is attached to the upper shaft of the pair of concrete molds 22 that are arranged to face each other, in accordance with the steps and the widths of the partition ventilation holes. Then, the top plate of the partitioning formwork is fixed to the upper shaft of the concrete formwork 22 with wedge stoppers or floating prevention metal fittings, and then the spacing holder 1 of this embodiment is placed between the partitioning formwork 21. Is inserted. The space holder 1 is adjusted to have an appropriate length so that the support plate 5 contacts the partitioning mold 21. In this state, the cloth foundation concrete 23 is poured and the pressure is applied to the partitioning mold 21. However, the partitioning mold 21 is not only deformed because the top plate is fixed not only by the wedge stoppers or the lifting prevention metal fittings but also by the interval holder 1 of this embodiment at the lower part.

Next, another embodiment of the present invention will be described with reference to FIG. Now, in the spacing member 19 of this another embodiment, the support plates 20 at both ends are bent, and a recess is formed in the central portion.

The spacing member 19 of this other embodiment is sandwiched between a pair of partitioning molds and can support the partitioning mold, as in the case of the first embodiment described above. In particular, when a handle is attached to the partition form, and the space holder of the first embodiment has a problem, the handle is housed in the recess of the support plate to securely support the partition form. It is possible.

The present invention is not limited to the configurations of the above-described embodiments, and the configurations of the respective parts can be arbitrarily modified and embodied without departing from the spirit of the invention.
