Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an auxiliary plate for attaching a floor sleeve, which is used when attaching a floor sleeve to a deck plate.

[Prior Art] In order to form through holes for piping and wiring in a concrete floor formed using a deck plate, a sleeve is attached to the deck plate in advance before concrete is poured. It is.

When attaching the sleeve to this deck plate, the deck plate has a shape with alternating peaks and valleys, and depending on the piping and wiring design, the sleeve may not necessarily be attached to the flat surface of the peaks or valleys. There are many cases in which it straddles peaks and valleys. Conventionally, when installing the sleeve in such a case, the opening end of the sleeve on the installation side is adjusted to match the shape of the peaks and valleys at the location where the through hole for piping and wiring is to be formed at the work site. Means such as processing by cutting or the like and attaching the opening end in close contact with the above-mentioned ridges and troughs has been adopted.

[Problems to be Solved by the Invention] According to the means for attaching the sleeve to the deck plate as described above, by processing the mounting side opening end of the sleeve to match the shape of the peaks and valleys of the deck plate, It is possible to prevent the concrete poured on the deck plate from entering the sleeve attached to the deck plate, but as mentioned above, the opening end of the sleeve on the installation side must be processed by the worker at the work site. Therefore, it is an extremely difficult task to process the mounting side open end of the sleeve so that it matches the shape of the deck plate at the position where the sleeve is to be mounted. Furthermore, the task of securely attaching such a sleeve to the deck plate is extremely troublesome, which makes the task of forming a concrete floor with through holes for piping and wiring extremely troublesome. There is a problem.

[Means for solving the problem] In view of the above-mentioned points, this invention has been developed in such a way that when the through hole for piping or wiring straddles the peaks and valleys of the deck plate, the surface of the peaks and valleys to which this sleeve is attached is A floor sleeve installation supplement designed to make installation work easier by eliminating the need for machining the installation opening end of the sleeve by making it flat, and to prevent poured concrete from penetrating into the sleeve. This invention provides an auxiliary plate, and this invention includes an upright side blocking plate formed in the same cross-sectional shape as the peaks and valleys of the deck plate, and an upright side blocking plate that is extended to the mountain side of this upright side blocking plate. It is characterized by comprising an upper shielding plate that spans the upper surfaces of adjacent peaks when the side shielding plates are fitted into the grooves formed by the peaks and valleys of the deck plate.

[Function] When the upright side shielding plate of the auxiliary plate according to this invention is fitted into the groove formed in the valley of the deck plate, the vertical side of the groove is closed by the upright side shielding plate. is blocked, and when the upright side blocking plate is fitted into the groove, the upper blocking plate extending to the mountain side of the upright side blocking plate straddles the top surface of the adjacent mountain, This upper shielding plate forms a flat surface between the upper surfaces of adjacent peaks. Therefore, if the sleeve to be attached to the deck plate spans one valley, prepare two auxiliary plates and fit the upright side shielding plates of the two auxiliary plates into the grooves of the deck plate to fix it. When the sleeve is attached to the deck plate so that the opening end of the sleeve is in contact with the flat surface formed by the upper surface of the adjacent peaks and the upper shielding plate that straddles these, the sleeve is attached to the deck plate. Concrete is prevented from entering the sleeve between the opening end on the installation side and the top surface of the mountain and the upper shielding plate, and the groove located below the sleeve is located at the upright side of the two auxiliary plates. Since the sleeve is closed off by the shielding plate, concrete is prevented from entering the sleeve from this groove.

[Example] Hereinafter, this invention will be described in detail based on an example shown in the drawings, but this invention is not limited to the example.

In the drawing, 1 is an auxiliary plate main body for attaching a floor sleeve, and this auxiliary plate main body 1
The upright side shielding plate 6 is formed to have the same cross-sectional shape as the groove 5 formed by the peaks 3 and valleys 4 of the deck plate 2, and on the mountain side of the upright side shielding plate 6,
It consists of an upper shielding plate 7 extending at right angles to this shielding plate 6, and this upper shielding plate 7 is formed when the upright side shielding plate 6 is fitted into the groove 5 of the deck plate 2. It is formed in such a size that its lower surface abuts and straddles the upper surfaces of the adjacent peaks 5, 5 with the concave groove 5 in between.
Although the upper shielding plate 7 has a trapezoidal shape in the embodiment, it is not limited to this shape. Reference numeral 8 denotes a fixing piece extending perpendicularly to the valley side of the upright side shielding plate 6, and when the blocking plate 6 is fitted into the groove 5, the lower surface of this fixing piece 8 aligns with the valley 4. It is designed to come into contact with the surface of the 9 is a hole.

Therefore, when the upright side shielding plate 6 of the auxiliary plate main body 1 for attaching a floor sleeve according to this invention is fitted into the groove 5 of the deck plate 2, both ends of the upright side shielding plate 6 are connected to the groove 5. The upper shielding plate 7 also straddles the upper surfaces of the adjacent peaks 5, 5 by contacting both side walls of the groove 5 and the valley sides thereof and the surfaces of the valley 4 to block the sides of the concave groove 5. The upper part of the groove 5 is closed to form a flat surface between the upper surfaces of the ridges 5, 5.

Auxiliary plate main body 1 for installing the floor sleeve
To explain an example of attaching the sleeve 10 to the deck plate 2 using the auxiliary plate body 1,
Prepare two grooves 5 as shown in Fig. 5.
The respective upright side shielding plates 6 are fitted and fixed. In this way, the sleeve 10 is attached to the flat surface formed on the upper surface between the peaks 5, 5 by the upper shielding plates 7 of the two auxiliary plate bodies 1 fixed to the deck plate 2. Since the mounting surface of the deck plate 10 is formed into a flat surface by the upper shielding plate 7 of the auxiliary plate 1, when the sleeve 10 is mounted, some processing is applied to the mounting side opening end of the sleeve 10. It can be installed without any trouble. In addition, since the concave groove in contact with the opening end on the installation side of the sleeve 10 is blocked by the upright side blocking plate 6 and the upper blocking plate 7, it will not be blocked when concrete is poured on the deck plate 2. Concrete is prevented from entering the groove and the sleeve 10.

[Effects of the invention] As described above, the auxiliary plate for attaching a floor sleeve according to the invention includes an upright side shielding plate formed in the same cross-sectional shape as the peaks and valleys of the deck plate;
The upper shield is extended to the upper side of the upright side shielding plate, and when the upright side shielding plate is fitted into the groove formed by the peaks and valleys of the deck plate, the upper shield extends over the top surface of the adjacent peaks. By fitting and fixing the auxiliary plate for installing the floor sleeve into the concave groove of the deck plate to which the sleeve is to be attached, the upper side of the deck plate can be fixed. Since a flat surface can be formed by the upper shielding plate, the sleeve can be attached to this flat surface, and therefore the sleeve can be attached without any processing required on the mounting opening end of the sleeve as in the conventional case. It can be easily attached to the deck plate, improving work efficiency.
Furthermore, the upright side shielding plate and upper shielding plate can reliably prevent poured concrete from entering the sleeve, making it extremely convenient as an auxiliary plate for installing floor sleeves. Furthermore, since the structure is simple, it is easy to manufacture and can be obtained at low cost.
