Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a formwork used when installing a ventilation hole plate in a cloth foundation under a foundation in construction.

[Prior Art] Conventionally, when mounting a ventilation hole plate in a cloth foundation, a space such as a wooden frame having a width suitable for the width of the ventilation hole plate is provided in advance in the process of forming the cloth foundation. After forming it, and then interposing a ventilation hole plate in the space, concrete is applied with a trowel or the like along the lower edge and both the left and right edges of the ventilation hole plate to complete.

[Problems to be solved by the device]

However, the work of forming a space in such a cloth foundation, and interposing a ventilation hole plate in the space and applying concrete to the periphery thereof is not only a very time-consuming work, but also the foundation after drying. It is technically difficult to apply concrete to concrete, and the bonding strength of the tissue is weak, and the ventilation hole plate is easy to come off due to vibration, impact, etc., and the finish is not good. there were.

[Means for Solving the Problem] The present invention is made to eliminate various disadvantages, and the ventilation hole plate can be mounted at the same time when the fabric foundation is completed. A formwork for mounting a vent plate is provided.

That is, the mounting formwork of the underfloor ventilation hole plate in the construction of the present invention comprises a front frame formed by continuously connecting the top plate and the left and right plates to the front plate while leaving the upper edge of the front plate, and a back frame. The top plate and the back frame formed by connecting the left and right plates in a row to the back plate are connected to the back plate, leaving the upper edge of the face plate, by hinges that are attached to the code parts of each top plate. A notch is provided in the sign part of the plate and each sign part of the left and right plates, and a stopper is rotatably interposed between the upper edge part of the front plate and the upper edge part of the back plate. And

〔Example〕

Hereinafter, an embodiment of a mounting form for an underfloor ventilation hole plate in a building of the present invention will be described in detail with reference to the drawings.

The formwork of the present invention, as shown in the figure, leaves the upper edge of the front plate 1 and the top plate 2, 3 and the left and right side plates 4, 5 on the front plate 1.
A front frame A formed by continuously connecting a main plate 3, a left side plate 4, and a right side plate 5 in an enclosing manner so as to incline inward, and the front plate 1 ′ except for the upper edge of the rear plate 1 ′. Top plate 2 ',
3'and left and right side plates 4 ', 5'include a base plate 3', a left side plate 4 ',
And a right side plate 5 ', and a back frame B formed by connecting them in an enclosing manner so as to incline inward, by hinges x, x, x straddled over the code portions of the respective top plates 2, 2'. While being connected, the main plate 3'side of the code portions of the main plate 3 and the main plate 3 ',
A notch F is provided on each of the left side plate 4'and the left side plate 4'on the left side plate 4'side, and on the right side plate 5'and the right side plate 5'on the right side plate 5'side, respectively. A stopper P is provided between the upper edge of the frame A and the upper edge of the rear frame B, and the base is rotatably pivoted inside the upper edge of the back plate 1'of the rear frame B. The stopper P is rotated to press the tip of the stopper P inside the upper edge of the front plate 1 in the front frame A, and the front frame A and the rear frame B are closed and sandwiched in the notch F. The ventilation hole plate 8 can be held.

In the figure, 6 is an L-shaped support arm with a vertical groove M that is vertically slidably mounted along a butterfly screw 7 screwed to the upper edge of the front plate 1 in the front frame A, and E is It is a U-shaped fastening fitting with a butterfly screw W. Moreover, H is a window hole provided as needed.

[Action]

According to the above-described form of the present invention, when mounting the ventilation hole plate in the cloth foundation using the present invention, first open the front frame A and the rear frame B of the present invention. , Then the back frame B
At the bottom plate 3'and the left and right side plates 4 ', 5', both ends and the lower end of the ventilation hole plate 8 are inserted into the notches F projecting slightly more than the bottom plate 3'and the left and right side plates 4 ', 5'. After closing the front frame A and the rear frame B at least, the stopper P provided between the upper edge of the front plate 1 and the upper edge of the rear plate 1'is rotated to rotate the stopper P. The front end of the front plate 1 is pressed against the inside of the upper edge of the front plate 1 to hold the ventilation hole plate 8 in the cutout portion F, and thereafter, as shown in FIG.
The above-mentioned mold 1 including the mold of the present invention by appropriately interposing between 10 and 10 '
When concrete is poured between 0 and 10 ', and when the concrete is dried and solidified, the left and right molds 10 and 10' are removed, and the front frame A and the rear frame B of the mold of the present invention are opened. As shown in FIG. 4, 8 is mounted by itself with its left and right ends and lower end embedded in the tissue of the base cloth.

〔effect〕

As described above, according to the present invention, the mold of the present invention, which holds the ventilation hole plate when forming the cloth foundation, is interposed between the left and right molds for forming the cloth foundation, and then concrete is poured and filled. After removing the cloth foundation forming mold after the concrete has dried to dryness, if the present invention mold is deployed, the ventilation hole plate is automatically fixed with both ends and the lower end embedded in the cloth foundation. The ventilation hole plate can be mounted on the cloth foundation easily and firmly and in good appearance without requiring the troublesome labor and technique as in the conventional case. Further, in the mold of the present invention, if a stopper provided between the upper edge of the front plate and the upper edge of the back plate is rotated and the tip of the stopper is pressed against the inside of the upper edge of the front plate. Since the ventilation hole plate is held in close contact with the front frame and the rear frame, it is possible to carry it while holding the ventilation hole plate in the formwork of the present invention.
The position of the ventilation hole plate does not shift when interposing it in the formwork for forming the cloth foundation, and it is easy to handle during work, and when the concrete is poured and filled, the concrete enters the formwork of the present invention. There is no fear of doing it.
