Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a small blockage of a deck plate used for building a floor of a building.

[0002]

[Prior art]

 In the conventional construction of buildings, in order to simplify the work and shorten the construction period, deck plates are laid on the beam-side formwork, and concrete is laid from the deck plates on the floor together with the beams. Is being built. The deck plate used in the construction of this floor has alternating peaks and valleys.When placing concrete from above the deck plates laid on the beam-side formwork, It is necessary to close the concrete so that concrete does not flow out from the end face opening.

Conventionally, as a small block for closing the end face opening of the mountain portion of the deck plate, Japanese Utility Model Publication No. 48-24978, Japanese Utility Model Publication No. 50-110013, Japanese Utility Model Publication No. 51-11892, and Japanese Utility Model Publication No. 52- JP-A-51692, JP-B-52-24354, JP-B-52-42578, JP-B-53-51043, JP-B2-111809, JP-A-3-5809, etc. There is. Most of these small blocks are to be inserted into the inside of the mountain end face opening of the deck plate and locked on both side edges or the upper edge or elastically held. The double-sided adhesive tape disclosed in Japanese Patent No. 5809 is attached to the inner surface of the bent upper edge only at the small edge block, and the double-sided adhesive tape is adhered to the upper surface of the mountain end face opening.

[0004] By the way, the above-mentioned conventional small edge insertion inserted inside the mountain end face opening portion of the deck plate requires much cutting and bending of the plate material, resulting in high manufacturing cost. Also, when concrete is poured, concrete enters the underside of the mountain part, so there was a risk that slag would leak and fall from the top of the beam-side formwork through the small block gap. Furthermore, the pouring of concrete swells the valley, which may move the edge block inserted inside the opening of the mountain end face. On the other hand, the small block that adheres to the upper surface of the mountain end face opening with double-sided adhesive tape cannot be firmly fixed, so there was a risk that the closed mountain end face opening would open when concrete was placed.

[0005]

[Problems to be solved by the device]

 Therefore, the present invention requires a small amount of processing, is inexpensive to manufacture, and prevents concrete from getting into the bottom side of the mountain portion of the deck plate when pouring concrete, and does not move by pouring concrete. It is intended to provide a small blockage of the deck plate so that it does not leak and fall from the side formwork.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, one of the small-sized block closures of the deck plate of the present invention is that an upper plate and a lower plate are alternately arranged in parallel, and the upper plate and the lower plate are connected by an inclined plate to form a mountain portion. Is a small block that closes the peak end face opening of the deck plate in which the peaks and the valleys are alternately continuous, and the small block is almost the same shape as the peak end face opening, and the left and right sides are slightly different from each other. A wider blocking plate, an upper insertion piece that is bent at the upper end of the closing plate and is inserted into the opening in contact with its inner upper surface, and a lower end of the closing plate in the same direction as the upper insertion piece. It is characterized in that it comprises a lower insertion piece that is bent and is inserted into the lower end of the mountain end face opening.

Another aspect of the present invention for closing the edge of the deck plate is that the upper plate and the lower plate are alternately parallel to each other, and the upper plate and the lower plate are bent in a dogleg shape in the middle. A small block that closes the peak end face opening of the deck plate in which the peaks and valleys are alternately connected and is connected by an inclined plate having the same height and wide width as the peak end face opening. A similar-shaped closing plate, an upper insertion piece that is bent at the upper end of the closing plate and is inserted into the opening of the mountain end face in contact with its inner upper surface, and the same direction as the upper insertion piece at the lower end of the closing plate. It is characterized in that it comprises a lower insertion piece which is bent and is inserted into the lower end of the mountain end face opening.

[0012] The two deck plates of the present invention configured as described above have a simple U-shape when viewed from the side, and therefore, the production is performed by one press punching of the plate material. It is simple and inexpensive because it can be bent on both the upper and lower sides. In addition, by inserting the upper insertion piece and the lower insertion piece into the upper and lower ends of the mountain end face opening of the deck plate, a closing plate wider than the mountain end face opening is locked to the mountain end face. The upper and lower inserts do not enter any more, and the closing plate is fixed by the spring effect of the upper and lower inserts, completely closing the peak end face opening. Therefore, when pouring concrete from above the deck plate to build a beam and floor, the concrete does not enter into the lower part of the mountain part of the deck plate, and from the beam side formwork where the deck plates are laid out. It prevents concrete slag from leaking and falling. Furthermore, the concrete is loaded into the valley from both sides of the mountain due to the pouring of concrete, and the opening on the end face of the mountain tends to deform. Since the piece is inserted to support the inclined plate, the deformation is suppressed, and the small block itself does not move, so that the sealing function can be achieved.

[0009]

[Embodiment of device]

 An embodiment of the small block closing of the deck plate of the present invention will be described with reference to the drawings. First, the deck plate to be used will be described with reference to FIG. 1. In the deck plate 1, upper plate 2 and lower plate 3 are alternately arranged in parallel, and the upper plate 2 and the lower plate 3 are in the middle. It is connected by an inclined plate 5 having a jaw 4 bent in a dogleg shape, and peaks 6 and valleys 7 are alternately continuous. As shown in FIG. 2, the edge block of the present invention for closing the end surface opening 8 of the mountain portion 6 of the deck plate 1 has the same height as the end surface opening 8 of the mountain portion 6 of the deck plate 1 and has a wide width and similar shape. The closing plate 9, that is, the closing plate 9 in which a dogleg-shaped jaw 10 is formed in the middle of the left and right end edges, and the end face opening 8 of the mountain portion 6 which is bent at the upper end of the closing plate 9 An upper insertion piece 11 that is inserted in contact with the inner upper surface and a lower insertion piece that is bent at the lower end of the closing plate 9 in the same direction as the upper insertion piece 11 and that is inserted at the lower end of the end face opening 8 of the mountain portion 6. It is composed of a piece 12. Since the edge block 13 of the embodiment having such a structure has a simple U-shape when viewed from the side, its manufacture is performed by using the plate material 14 shown in FIG. As shown in FIG. 4, it is sufficient to form the upper insertion piece 11 and the lower insertion piece 12 on both upper and lower sides by bending once. Therefore, it can be manufactured easily and inexpensively.

In addition, the edge block 13 of the embodiment is a deck plate in which the upper insertion piece 11 and the lower insertion piece 12 are laid side by side on a horizontal tree 16 at the opening edge of the beam-side frame 15 as shown in FIG.

Therefore, when concrete is poured from above the deck plate 1 to build a floor together with the beams, the concrete does not enter below the mountain portion 6 of the deck plate 1, and the beam side formwork in which the deck plates 1 are laid side by side. 15 It is possible to prevent concrete slag from leaking and dropping from above.

Further, when concrete is poured, a concrete load of the valley portion 7 is applied from both sides of the mountain portion 6 and the end face opening portion 8 of the mountain portion 6 is about to be deformed. However, the end face opening portion 8 of the mountain portion 6 is deformed. The upper insert piece 11 and the lower insert piece 12 are inserted into the upper and lower ends of the inclined plate 5 to support the upper and lower ends of the inclined plate 5 so that deformation is suppressed, and the forehead blocker 13 itself does not move, and the sealing function is achieved. You can Moreover, when the end portion of the deck plate 1 is laid inside the beam-side formwork 15 and the bottom insertion piece 12 of the fore edge blocker 13 is laid side by side, the concrete of the beam portion leaks from the open end surface of the mountain portion 6. Can be prevented.

The edge block 13 of the above-described embodiment has a mountain portion 6 of the deck plate 1 having a jaw 4 bent in a dogleg shape in the middle of the inclined plate 5 connecting the upper plate 2 and the lower plate 3. The end face opening 8 is closed, and the end face opening corresponds to claim 2, but as shown in FIG. 6, the end face opening of the mountain portion 6 of the deck plate 1'without the jaw 4 on the tilting plate 5 is shown. The closing plate 9 ′ of the edge block 13 ′ corresponding to the claim 1 for closing 8 has substantially the same shape as the end face opening 8 of the mountain portion 6, and the left and right sides are slightly wider than the end face opening 8 of the mountain portion 6. Has become.

[Effect of device]

 As can be seen from the above description, the fore-edge closing of the deck plate of the present invention is extremely simple in structure, requires little processing, and can be easily manufactured at low cost. Also, by inserting the upper insert piece and the lower insert piece into the upper and lower ends of the end face openings of the mountain portions of the deck plates laid on the beam-side formwork, the closing plate is locked to the end faces of the mountain portions. Since the end face opening is completely blocked by the concrete, when pouring concrete from above the deck plate to build the floor with the beams, the concrete does not enter the bottom side of the deck plate mountain, and the concrete slag is removed. Leakage and fall from the beam-side formwork are prevented. In addition, the upper and lower inserts are inserted at the upper and lower ends of the opening on the end face of the mountain to support the inclined plate, so deformation is suppressed and the small block itself does not move, achieving the sealing function. be able to. Moreover, the lower plugging piece of the small block can prevent the concrete of the beam from leaking from the open end face of the mountain when the end of the deck plate is laid inside the beam-side formwork.
